================================================================================

(1)  Represents the maximum  amount of common stock,  par value $1.00 per share,
     of Orion Capital Corporation  ("Orion"),  issuable upon consummation of the
     exchange offer for outstanding  shares of common stock, par value $1.00 per
     share (the "Shares"),  of Guaranty  National  Corporation  ("Guaranty") not
     owned by Orion and its  wholly-owned  subsidiaries  (the "Tender  Shares"),
     based  on the  maximum  Exchange  Ratio  (as  defined  in the  Prospectus).
     According to Guaranty's Quarterly Report on Form 10-Q for the quarter ended
     June 30,  1997,  as of August 4,  1997,  there were issued and  outstanding
     15,038,433 Shares. Excluding the Shares owned by Orion and its wholly-owned
     subsidiaries,  based on the foregoing and assuming that no Shares have been
     issued since August 4, 1997,  the maximum  number of Shares  subject to the
     Offer (as defined in the Prospectus) would be 479,809.  However, the actual
     maximum  number of Tender  Shares will depend on the facts as they exist on
     the Expiration Date (as defined in the Prospectus).

(2)  Pursuant to Rules 457(f) and 457(c) under the  Securities  Act of 1933,  as
     amended,  and solely for the purpose of calculating the  registration  fee,
     the  registration fee has been computed on the basis of the market value of
     shares  of Orion  Common  Stock on the  basis of the  average  high and low
     prices  per  share of such  stock  as  represented  on the New  York  Stock
     Exchange  Composite  Tape on  September  19,  1997.  The fee is  $6,333.84,
     calculated  as  1/33  of one  percent  of the  Proposed  Maximum  Aggregate
     Offering Price.

Orion Capital Corporation, a Delaware corporation ("Orion"), hereby offers, upon
the terms and  subject to the  conditions  set forth  herein and in the  related
Letter of Transmittal  (collectively,  the "Offer"),  to exchange  $27.20 net in
cash and $6.80 in shares of common  stock,  par value $1.00 per share,  of Orion
("Orion  Common  Stock"),  subject to adjustment as described  herein,  for each
outstanding  share of common stock,  par value $1.00 per share (each,  a "Share"
and collectively,  the "Shares"), of Guaranty National Corporation ("Guaranty"),
a company  incorporated  under the laws of Colorado,  other than Shares owned by
Orion and its wholly-owned subsidiaries, including (unless and until Orion shall
declare that the Rights Condition (as defined below) has been invoked by it) the
associated  stock  purchase  rights  (each,  a  "Right"  and  collectively,  the
"Rights")  issued  pursuant to the  Shareholder  Rights  Agreement,  dated as of
November  20,  1991,  between  Guaranty and  ChaseMellon  Shareholder  Services,
L.L.C., as Rights Agent (the "Rights  Agreement"),  validly tendered on or prior
to the Expiration Date and not properly withdrawn. The exact number of shares of
Orion  Common  Stock to be delivered  for each Share will be  determined  on the
Expiration  Date as more  fully  described  below.  See "The  Offer --  Exchange
Ratio." As of September 18, 1997, Orion and its wholly-owned  subsidiaries owned
approximately 81% of the outstanding  Shares as of August 4, 1997 as reported in
Guaranty's  Quarterly  Report on Form 10-Q for the period  ended June 30,  1997.
Unless  the  context  otherwise  requires  or unless  and until the  Rights  are
redeemed,  all  references to Shares shall include the  associated  Rights.  All
references herein to Rights shall include all benefits that may inure to holders
of the Rights pursuant to the Rights  Agreement.  Each Share validly tendered on
or prior to the Expiration  Date and not properly  withdrawn will be entitled to
receive $27.20 net in cash and that number of shares of Orion Common Stock equal
to the Exchange Ratio (as defined below) (together, the "Offer Consideration").

         THESE   SECURITIES  HAVE  NOT  BEEN  APPROVED  OR  DISAPPROVED  BY  THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES  COMMISSION,  NOR HAS
THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PRELIMINARY PROSPECTUS. ANY REPRESENTATION
TO THE CONTRARY IS A CRIMINAL OFFENSE.

                      The Dealer Manager for the Offer is:

               Donaldson, Lufkin & Jenrette Securities Corporation
                                 277 Park Avenue
                            New York, New York 10172
                The date of this Prospectus is ________ __, 1997.

         The term  "Exchange  Ratio" means the quotient  (rounded to the nearest
1/100,000) determined by dividing $6.80 by the average of the high and low sales
prices of Orion Common Stock (as reported on the New York Stock  Exchange,  Inc.
(the "NYSE")  Composite  Transactions  reporting system as published in The Wall
Street Journal or, if not published therein,  in another  authoritative  source)
(the "Orion Average Price") on each of the ten  consecutive  trading days ending
with the fifth trading day immediately  preceding the Expiration Date,  provided
that the  Exchange  Ratio shall not be greater than .1650 shares of Orion Common


                                       6
<PAGE>

Stock and shall not be less than  .1420  shares of Orion  Common  Stock for each
Share.  See "The  Offer--The  Exchange  Ratio." Orion Common Stock is listed for
trading under the symbol "OC" on the NYSE.  On September  19, 1997,  the closing
price of Orion Common Stock on the NYSE was $44.00. Based on such closing price,
the  Exchange  Ratio would be .1545 shares of Orion Common Stock for each Share.
The  Exchange  Ratio  will  change as the  market  price of Orion  Common  Stock
changes;  changes in the market  price of the Shares  after the date hereof will
not affect the Exchange  Ratio.  A press release will be issued  announcing  the
actual  Exchange  Ratio prior to the opening of the fourth  trading day prior to
the  Expiration  Date (as it may be  extended  from time to time).  If the Orion
Average  Price should be greater  than $51.25 or less than $37.88,  Orion may in
its sole  discretion  refuse to accept Shares  tendered for  exchange.  See "The
Offer -- the Exchange Ratio."

         ORION'S  OBLIGATION  TO  EXCHANGE  THE OFFER  CONSIDERATION  FOR SHARES
PURSUANT TO THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS,  THE SATISFACTION
OR,  WHERE  APPLICABLE,  WAIVER OF THE  FOLLOWING  CONDITIONS:  (i) THERE  BEING
VALIDLY  TENDERED AND NOT  WITHDRAWN  PRIOR TO THE  EXPIRATION  DATE A NUMBER OF
SHARES WHICH, EXCLUDING SHARES OWNED BY ORION AND ITS WHOLLY-OWNED  SUBSIDIARIES
AFFILIATES (THE "TENDER  SHARES"),  WILL CONSTITUTE AT LEAST 50.01% OF THE TOTAL
NUMBER OF  OUTSTANDING  TENDER SHARES AS OF THE DATE THE SHARES ARE ACCEPTED FOR
EXCHANGE BY ORION  PURSUANT TO THE OFFER (THE "MINIMUM SHARE  CONDITION"),  (ii)
ORION BEING  SATISFIED IN ITS SOLE DISCRETION THAT THE RIGHTS ARE INVALID OR ARE
NOT APPLICABLE TO THE  ACQUISITION OF SHARES BY ORION PURSUANT TO THE OFFER (THE
"RIGHTS PLAN  CONDITION"),  (iii) THE ORION AVERAGE PRICE NOT BEING GREATER THAN
$51.25 OR LESS THAN $37.88 (THE "ORION AVERAGE PRICE  CONDITION"),  AND (iv) ALL
REGULATORY  APPROVALS  REQUIRED TO CONSUMMATE THE OFFER HAVING BEEN OBTAINED AND
REMAINING IN FULL FORCE AND EFFECT,  ALL  STATUTORY  WAITING  PERIODS IN RESPECT
THEREOF  HAVING  EXPIRED  AND NO SUCH  APPROVAL  CONTAINING  ANY  CONDITIONS  OR
RESTRICTIONS  WHICH THE ORION BOARD OF DIRECTORS (THE "ORION BOARD")  DETERMINES
WILL OR COULD BE  EXPECTED  MATERIALLY  TO IMPAIR THE  STRATEGIC  AND  FINANCIAL
BENEFITS   EXPECTED  TO  RESULT  FROM  THE  OFFER  (THE   "REGULATORY   APPROVAL
CONDITION").  THE MINIMUM SHARE CONDITION,  THE RIGHTS PLAN CONDITION, THE ORION
AVERAGE  PRICE  CONDITION,  THE  REGULATORY  APPROVAL  CONDITION  AND THE  OTHER
CONDITIONS  SET FORTH UNDER THE CAPTION "THE  OFFER--CERTAIN  CONDITIONS  OF THE
OFFER" SHALL BE REFERRED TO COLLECTIVELY AS THE "OFFER CONDITIONS."

         Orion  reserves  the right to extend the Offer from time to time in its
sole  discretion  beyond the Expiration Date in order,  among other reasons,  to
permit the conditions to the Offer to be satisfied.  Capitalized  terms used but
not defined above are defined hereinafter.

                                    IMPORTANT

         Any Guaranty  shareholder  desiring to tender all or any portion of his
or her Shares and the associated  Rights should either (a) complete and sign the
Letter of  Transmittal  or a  facsimile  copy  thereof  in  accordance  with the
instructions  in the Letter of  Transmittal,  and mail or deliver  the Letter of
Transmittal or such  facsimile and any other required  documents to State Street
Bank  and  Trust  Company  (the   "Exchange   Agent")  and  either  deliver  the
certificates for such Shares and, if separate,  certificates for the Rights,  to
the  Exchange  Agent along with the Letter of  Transmittal,  deliver such Shares
(and Rights, if applicable)  pursuant to the procedures for book-entry  transfer
set forth herein (in the case of Rights,  only if such procedures are available)
or comply with the guaranteed delivery procedures set forth below or (b) request
his or her broker,  dealer,  commercial  bank, trust company or other nominee to
effect the transaction for such Guaranty  shareholder.  Any Guaranty shareholder
having  Shares and, if  applicable,  Rights  registered in the name of a broker,
dealer, commercial bank, trust company or other nominee is urged to contact such
broker,  dealer,  commercial  bank,  trust company or other nominee if he or she
desires to tender such Shares and, if applicable, Rights.

         Guaranty  shareholders  will be  required  to tender one Right for each
Share  tendered  in order to effect a valid  tender of Shares,  unless and until
Orion declares that the Rights Plan Condition is satisfied. Unless and until the
Guaranty  Distribution  Date (as defined herein) occurs, a tender of Shares will
constitute a tender of the associated Rights.

         Any  Guaranty  shareholder  that  desires  to  tender  Shares  and,  if
applicable,  Rights,  and whose certificates for such Shares and, if applicable,
Rights are not  immediately  available or who cannot comply with the  procedures
for  book-entry  transfer on a timely  basis or who cannot  deliver all required
documents to the Exchange  Agent prior to the  Expiration  Date, may tender such
Shares and, if  applicable,  Rights,  by following the procedure for  guaranteed
delivery.

         Questions  and  requests  for   assistance   may  be  directed  to  the
Information  Agent or to the Dealer  Manager at their  respective  addresses and
telephone  numbers set forth on the back cover of this Prospectus.  Requests for
additional  copies  of this  Prospectus  and the  Letter of  Transmittal  may be
directed  to the  Information  Agent or to the  Dealer  Manager  or to  brokers,
dealers, commercial banks or trust companies.

         All statements made in this  Prospectus that do not reflect  historical
information are  "forward-looking  statements" within the meaning of the Private
Securities  Litigation  Reform  Act of 1995.  Such  forward  looking  statements
involve known and unknown risks,  uncertainties and other factors that may cause
the actual results,  performance or  achievements of Orion and its  consolidated
subsidiaries  (including  Guaranty) to be materially  different  from any future
results,   performance   or   achievements,   expressed   or   implied   by  the


                                       8

forward-looking statements. Such risks, uncertainties and other factors include,
among other things, (i) general economic and business  condition;  (ii) interest
rate  and  financial  market  changes;  (iii)  competition  and  the  regulatory
environment  in which Orion and such  consolidated  subsidiaries  operate;  (iv)
claims  frequency;  (v) claims  severity;  (vi)  medical cost  inflation;  (vii)
increases in the cost of property  repair;  (viii) the number of new and renewal
policy applications submitted to Orion and such consolidated subsidiaries;  (ix)

factors over which Orion and such  consolidated  subsidiaries  have little or no
control.  Orion  disclaims any obligation to update or to announce  publicly the
impact of any such  factors or revisions to any  forward-looking  statements  to
reflect future events or developments.

                               PROSPECTUS SUMMARY

         THE INFORMATION BELOW IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND FINANCIAL  STATEMENTS  APPEARING  ELSEWHERE IN THIS  PROSPECTUS,
INCLUDING THE DOCUMENTS  INCORPORATED IN THIS PROSPECTUS BY REFERENCE.  GUARANTY
SHAREHOLDERS  ARE URGED TO READ THIS  PROSPECTUS AND THE ANNEXES HERETO (SETTING
FORTH CERTAIN INFORMATION ABOUT OFFICERS AND DIRECTORS OF ORION AND GUARANTY AND
THEIR   OWNERSHIP  OF  ORION  COMMON  STOCK  AND  SHARES),   AND  THE  DOCUMENTS
INCORPORATED HEREIN BY REFERENCE, IN THEIR ENTIRETY. AS USED IN THIS PROSPECTUS,
THE TERMS "ORION" AND  "GUARANTY"  REFER TO SUCH ENTITY AND,  UNLESS THE CONTEXT
OTHERWISE REQUIRES,  ITS SUBSIDIARIES.  ON JUNE 5, 1997 ORION DECLARED A 2-FOR-1
SPLIT OF ITS COMMON STOCK PAYABLE ON JULY 7, 1997 TO  SHAREHOLDERS  OF RECORD ON
JUNE 23, 1997.  ALL ORION  COMMON  STOCK AND PER COMMON SHARE DATA  PRESENTED IN
THIS PROSPECTUS HAS BEEN RESTATED TO GIVE EFFECT TO THIS STOCK SPLIT.

THE COMPANIES

         ORION.  Orion is a property and  casualty  insurance  holding  company.
Orion's  insurance  subsidiaries and affiliates are authorized to underwrite and
sell most types of property and casualty insurance. Orion's insurance businesses
are concentrated in niche insurance markets, particularly workers' compensation,
professional liability,  nonstandard automobile insurance and underwriting ocean
marine, inland marine and property insurance through underwriting pools. For the
five-year  period  ended  December  31,  1996,  Orion's  return on  equity  from
operating earnings (earnings after taxes,  excluding the effects of the adoption
of  new  accounting  principles,  extraordinary  items  and  after-tax  realized
investment  gains)  averaged  14.25% per year.  The  combined  ratio for Orion's
insurance  operations,  computed on the basis of generally  accepted  accounting
principles,  has steadily improved from 105.4% in 1992 to 99.8% in 1996. For the
first six  months of 1997,  the  annualized  return  on  equity  from  operating
earnings was 13.13%, and the combined ratio was 100.0%.  From 1991 until July of
1996 Orion maintained an ownership interest in Guaranty of approximately 49%. In
July of 1996 Orion  completed a public  tender offer for  Guaranty  Common Stock
increasing its ownership  interest to approximately  81%, which percentage Orion
maintains at the present time.  Orion's principal  executive offices are located
at 9 Farm Springs Road,  Farmington,  Connecticut 06032 and the telephone number
at such location is (860) 674-6600.

         GUARANTY.  Guaranty is a holding  company whose  principal  business is
conducted  through  wholly-owned  subsidiaries.  Guaranty  and its  subsidiaries
principally  underwrite  and sell  specialty  property  and  casualty  insurance
coverages  which are not readily  available in  traditional  insurance  markets.
Personal and commercial  automobile insurance accounted for approximately 84% of
Guaranty's net premiums written during 1996. Its personal lines unit principally
writes nonstandard  automobile  insurance for individuals who do not qualify for
preferred  or  standard  insurance  because of their  payment  history,  driving
records, ages, vehicle types, or other factors,  including market conditions for
standard risks. Guaranty also markets collateral protection business. Guaranty's
commercial  lines unit  principally  writes  nonstandard  commercial  automobile
coverage.  However,  approximately  29% of the total commercial lines unit's net
premiums written consist of standard commercial coverage.  Typical risks include


                                       17
<PAGE>

local and intermediate trucking,  garages, used car dealers,  public and private
livery,  and artisan  contractors.  Other  commercial  lines  coverages  include
property, general liability, umbrella and excess insurance, standard multi-peril
packages and other coverages. Guaranty's principal executive offices are located
at 9800 South Meridian Boulevard,  Englewood,  Colorado 80112, and its telephone
number is (303) 754-8400.

RISK FACTORS

         In addition to the other  information in this  Prospectus,  a number of
factors  should be  considered  by  Guaranty  shareholders,  including,  without
limitation,  the  effects  of full  integration  of the  operation  of Orion and
Guaranty,  underwriting risks, volatility of the insurance industry,  inflation,
competition and governmental regulation,  all of which may have an impact on the
performance of Orion after the Offer has been consummated.

See "Risk Factors."

SPECIAL FACTORS

         BACKGROUND OF THE OFFER.  Orion has owned a substantial equity interest
in Guaranty  since 1984,  and from 1988 through 1991 Guaranty was a wholly-owned
subsidiary  of Orion.  In 1996,  Orion  increased  its  ownership of Shares from
slightly  less than 50% of the  outstanding  Shares to  approximately  81%. As a
result,  Guaranty is now included in the consolidated tax return of Orion.  With
its  increased  ownership,  senior  management  of Orion  assumed a more  active
participation   with  senior  management  of  Guaranty  in  the  development  of
Guaranty's strategic plans.

         Early in 1997, senior management of Orion concluded that while Guaranty
is well  positioned  to  compete in the market  for  nonstandard  personal  auto
insurance,  its  strategic  growth  plans will  require  capital  beyond what is
presently on hand and expected to be generated from operations.

         REASONS FOR THE OFFER. Orion believes it can provide to Guaranty,  as a
wholly-owned subsidiary,  access to capital in amounts and on terms that may not
be available to Guaranty as a separate,  independent  entity.  In order to place
Guaranty  in a  position  to carry  out its  strategic  plans  on a  timely  and
adequately-financed basis, and to protect the significant investment which Orion
presently  has in Guaranty,  Orion has  determined to seek to acquire the Shares
which  it  does  not  presently  own.  To the  extent  that  any  Shares  remain
outstanding  following  completion  of the  present  Offer,  Orion  will seek to
acquire them either in a merger,  or in a subsequent  tender offer on such terms
and conditions as may seem  appropriate at the time,  which terms and conditions
may be the same as or different from the terms and conditions of this Offer.

         Orion also believes that Guaranty  shareholders who tender their Shares
for  exchange  pursuant  to the  Offer  will have the  opportunity  to retain an
indirect  equity  interest  in  the  business  of  Guaranty,  as a  wholly-owned
subsidiary of Orion,  through their equity ownership of Orion, a larger,  better
capitalized  company. See "Special Factors -- Reasons for the Offer; Purpose and
Structure of the Transaction; Plans After the Offer; Effects of the Offer."



                                       18
<PAGE>

         FAIRNESS  OF THE OFFER.  Orion  believes  that the Offer is fair to the
unaffiliated holders of Shares to whom it is directed.  For a description of the
factors considered by Orion, see "Special Factors -- Fairness of the Offer."

THE OFFER

         Pursuant to the terms of the Offer, Orion hereby offers, upon the terms
and subject to the  conditions  set forth  herein and in the  related  Letter of

collectively the "Shares"), of Guaranty, other than Shares owned by Orion or its
wholly-owned subsidiaries, including the associated stock purchase rights.

         PROCEDURES  FOR  TENDERING  SHARES.  Tendering  holders of Shares  must
complete and sign a Letter of  Transmittal in accordance  with the  instructions
contained  therein  and forward the same by mail,  facsimile  or hand  delivery,
together with any other required  documents,  to the Exchange Agent, either with
the Shares to be tendered or in  compliance  with the specified  procedures  for
guaranteed delivery of Shares. Certain brokers, dealers, commercial banks, trust
companies and other  nominees may also effect  tenders by  book-entry  transfer.
Holders of Shares registered in the name of a broker,  dealer,  commercial bank,
trust company or other nominee are urged to contact such person promptly if they
wish to tender  Shares  pursuant  to the  Offer.  See "The Offer -- Terms of the
Offer."

Street  Bank and Trust  Company  (the  "Exchange  Agent").  The  addresses,  and
telephone and facsimile numbers, of the Exchange Agent are set forth on the back

         HOLDERS OF SHARES ARE URGED TO OBTAIN  CURRENT  MARKET  QUOTATIONS  FOR

DESCRIPTION OF ORION COMMON STOCK

         The holders of outstanding shares of Orion Common Stock are entitled to
receive dividends out of assets legally available  therefor at such times and in
such  amounts  as the  Orion  Board  may  from  time  to  time  determine.  Each
shareholder is entitled to one vote for each share of Orion Common Stock held on
all  matters  submitted  to a vote of  shareholders.  Cumulative  voting for the
election  of  directors  is  not  provided  for  in  the  Orion  Certificate  of
Incorporation,  which means that the  holders of a majority of the shares  voted
can elect all of the  directors  then  standing for  election.  The Orion Common
Stock is not entitled to  preemptive  rights and is not subject to conversion or
redemption.  Upon  liquidation,  dissolution or winding up of Orion,  the assets
legally  available for  distribution to shareholders are  distributable  ratably
among the  holders  of the Orion  Common  Stock  outstanding  at that time after


                                       20
<PAGE>

payment of other claims of  creditors.  Each  outstanding  share of Orion Common
Stock is,  and all shares of Orion  Common  Stock to be issued in the Offer will
be, fully paid and nonassessable.

COMPARATIVE RIGHTS OF SHAREHOLDERS

         There are differences  between the rights of Guaranty  shareholders and
the  rights  of  Orion   shareholders   resulting  from,  among  other  matters,
differences  between the  governing  instruments  of Guaranty  and Orion.  For a
discussion of certain  differences  between the rights of Guaranty  shareholders
and the rights of Orion shareholders, see "Comparative Rights of Shareholders."

                             SELECTED FINANCIAL DATA

                            ORION CAPITAL CORPORATION

         The  summary  below  should be read in  connection  with the  financial
information  included in Orion's  10-K for the year ended  December 31, 1996 and
Quarterly  Reports on Form 10-Q for the periods ended March 31 and June 30, 1997
incorporated by reference into this Prospectus.  Interim  unaudited data for the
six months ended June 30, 1997 and 1996 reflect, in the opinion of management of
Orion,  all  adjustments  (consisting  only  of  normal  recurring  adjustments)
necessary for a fair presentation of such data. Results for the six months ended
June 30, 1997 are not  necessarily  indicative  of results which may be expected
for any other interim period or for the year as a whole.

         In November 1991,  Orion reduced its ownership of Guaranty from 100% to
49.3%.  Orion owned  slightly less than 50% of Guaranty from November 1991 until
Orion increased its ownership to 81% in July 1996. For the six months ended June
30, 1997 and 1996, and the year ended December 31, 1996, Guaranty is included in
the financial statements of Orion on a consolidated basis with recorded minority
interest.  For all other periods  presented,  Orion's  investment in Guaranty is
accounted for using the equity method.

         All Orion  Common Stock and per common  share data  presented  has been
restated to give effect to the 2-for-1 stock split of its Common Stock  declared
on June 5,  1997,  and the  5-for-4  stock  split of its Common  Stock  declared
October 15, 1993.

         The  summary  below  should be read in  connection  with the  financial

management of Guaranty,  all adjustments  (consisting  only of normal  recurring
adjustments) necessary for a fair presentation of such data. Results for the six
months ended June 30, 1997 are not  necessarily  indicative of results which may
be expected for any other interim period or for the year as a whole.

                                  RISK FACTORS

         EACH GUARANTY  SHAREHOLDER  SHOULD CAREFULLY  CONSIDER AND EVALUATE THE
FOLLOWING FACTORS:

UNCERTAINTIES RELATING TO EFFECTS OF THE OFFER

         INTEGRATION OF OPERATIONS.  Orion and Guaranty have already  achieved a
significant  level of  cooperation  and Orion  expects that causing  Guaranty to
become  a  wholly-owned   subsidiary   will  result  in  additional   beneficial
synergistic  effects.  See "Special Factors -- Reasons for the Offer." Achieving
those  anticipated  benefits  will depend in  significant  part,  however,  upon
whether  the  efficiencies  expected  are  achieved in a timely,  efficient  and
effective  manner,  and there can be no  assurance  that  this will  occur.  The
further  integration  of the operations of two  organizations  could require the
dedication  of management  resources  which may  temporarily  distract them from
attention to the day-to-day  business of the combined  company.  The process may
cause an interruption  of, or a loss of momentum in, the activities of either or
both of the  companies'  businesses  and may  materially  adversely  affect  the
revenue and results of operations of the combined company,  at least in the near
term. In addition,  the further  process of combining the companies could have a
material  adverse  effect on employee  morale and on the ability of the combined
company  to  retain  key  management,  underwriting,  and  sales  and  marketing
personnel who are critical to both companies' future  operations.  The potential
loss of key  employees  could  result in a  material  loss of  business  to both
companies, although Orion does not believe that will be the case.

         TRANSACTION   COSTS.   Orion   estimates  that  it  will  incur  direct
transaction  costs of approximately  $_______  associated with the Offer.  These
amounts are preliminary  estimates only and therefore  subject to change.  These
expenses  include  fees  for  financial  advisors,  legal  counsel,  independent
auditors and printing charges. Orion expects that Guaranty will also incur costs
of this sort.  There can be no assurance  that Orion and Guaranty will not incur
additional  charges in subsequent  quarters to reflect costs associated with the
Offer. See "The Offer -- Fees and Expenses."

RISKS RELATING TO ORION AND GUARANTY

         UNDERWRITING  RISKS.  Orion and its  subsidiaries  other than  Guaranty
provide a broader  range of property  and casualty  insurance  than is presently
offered by Guaranty.  Their  profitability  is,  therefore,  more susceptible to
losses caused by a wider range of risks, such as earthquakes, windstorms, floods
and other severe  weather  conditions  or natural  disasters.  In recent  years,
natural  disasters such as hurricanes,  earthquakes in California and Japan, and
windstorms  in Europe have  resulted in  significant  losses to the property and
casualty insurance  industry.  Orion's results of operations and cash flows have
not been materially and adversely  affected by such natural  disasters but there
can be no  assurances  that future  natural  disasters  will not have a material
adverse effect on Orion's or Guaranty's results of operations.

         FLUCTUATION AND UNCERTAINTY OF PROPERTY AND CASUALTY INSURANCE INDUSTRY
RESULTS.  The  results of  companies  in the  property  and  casualty  insurance
industry  historically  have  been  subject  to  significant   fluctuations  and


                                       26
<PAGE>

uncertainties.  The industry's  profitability  can be affected  significantly by
volatile and unpredictable  developments  (including  catastrophes);  changes in
reserves  resulting from the general claims and legal  environments as different
types of claims  arise and  judicial  interpretations  relating  to the scope of
insurers' liability develop; fluctuations in interest rates and other changes in
the  investment  environment  which  affect  returns on  invested  capital;  and
inflationary  pressures that affect the size of losses.  The demand for property
and casualty  insurance  can also vary  significantly,  generally  rising as the
overall  level of  economic  activity  increases  and  falling as such  activity
decreases.  The property and casualty insurance  industry  historically has been
cyclical,  and  the  industry  as a  whole  has,  since  the  late  1980s,  been
characterized  by aggressive  premium rate  competition,  which has from time to
time resulted in lower underwriting profitability. Orion's results of operations
are subject to being adversely affected by these fluctuations and uncertainties.

         UNCERTAINTY  REGARDING  ADEQUACY OF LOSS  RESERVES.  Orion and Guaranty
establish  loss reserves to make  reasonable  and  sufficient  provision for the
estimated  ultimate  liability  for losses  and loss  adjustment  expenses  with
respect  to  reported  and  unreported  claims  incurred  as of the  end of each
accounting period.  Reserves do not represent an exact calculation of liability,
but instead represent estimates,  generally involving actuarial projections at a
given  time,  of what  Orion and  Guaranty,  respectively  expect  the  ultimate
settlement and  administration  of claims will cost based on assessment of facts
and  circumstances  then known,  estimates of future trends in claims  severity,
frequency, judicial theories of liability and other factors. These variables are
affected  by both  internal  and  external  events,  such as  changes  in claims
handling  procedures,   economic  inflation,  judicial  trends  and  legislative
changes.  Many of these items are not directly  quantifiable,  particularly on a
prospective basis. Additionally, there may be significant reporting lags between
the  occurrence of an insured event and the time it is actually  reported to the
insurer.  Reserve estimates are continually refined in a regular ongoing process
as  experience  develops and claims are reported  and  settled.  Adjustments  to
reserves are reflected in the results of operations in the periods in which such
estimates  are  changed.  Because  establishment  of reserves  is an  inherently
uncertain  process  involving  estimates  of  future  losses,  there  can  be no
certainty  that currently  established  reserves will prove adequate in light of
subsequent  actual  experience.  The inherent  uncertainties  of estimating loss
reserves  are  generally  greater  for  casualty  coverages  than  for  property
coverages,  due  primarily to the longer period of time that  typically  elapses
before a  definitive  determination  of  ultimate  loss  can be  made,  changing
theories  of legal  liability  involving  certain  types of claims and  changing
political climates.

         REINSURANCE   CONSIDERATIONS.   Orion's  and  Guaranty's  property  and
casualty  insurance  business is partially  dependent upon their ability to cede
significant  amounts  of the risk  insured  by Orion or  Guaranty.  The  amount,
availability and cost of reinsurance protection are subject to prevailing market
conditions beyond the control of Orion or Guaranty,  and may affect the level of
business and  profitability  of Orion or  Guaranty.  Orion and Guaranty are also
subject to credit risk with respect to the reinsurers to which business has been
ceded, since the ceding of risk to reinsurers does not relieve the participating
insurers or reinsurers under the facilities of their liability to their insureds
or reinsureds. No assurances can be given as to Orion's or Guaranty's ability to
maintain their current reinsurance  protection  facilities,  which generally are
subject to annual  renewal.  If Orion or Guaranty  were unable to maintain  such


                                       27
<PAGE>

facilities upon their expiration,  either its net exposures would increase,  or,
if it were unwilling to bear such increase in net  exposures,  Orion or Guaranty
would be required to reduce the level of its underwriting commitments.

         COMPETITION.  The insurance  business is generally highly  competitive.
Orion and Guaranty face competition from domestic and foreign insurers,  some of
whom are larger and have greater financial,  marketing and management  resources
than Orion and Guaranty.  Both Orion's and Guaranty's  profitability is affected
by many other  factors,  including rate  competition,  severity and frequency of
claims, interest rates, state regulations, court decisions, the judicial climate
and general business  conditions,  all of which are outside the control of Orion
and Guaranty.

         REGULATION   AND   LICENSING.   Orion  and   Guaranty  are  subject  to
governmental  regulation in each of the states in which each conducts  business.
Such  regulation  is vested in state  agencies,  which have  broad  supervisory,
regulatory and administrative powers to deal with all aspects of the business of
Orion and Guaranty,  including licenses,  rates, policy forms, capital adequacy,
payment of dividends,  security  deposits,  methods of accounting,  investments,
form and  content of  financial  statements,  reserves  for unpaid loss and loss
adjustment expenses,  reinsurance,  standards of solvency, periodic examinations
and annual and other report filings. A change in such laws and regulations could
adversely  affect the revenues and expenses of Orion and  Guaranty.  In general,
state  agencies are primarily  concerned  with the  protection of  policyholders
rather than shareholders.  In recent years state legislatures have considered or
enacted laws that alter and, in many cases, increase state authority to regulate
insurance  companies and insurance  holding company  systems.  In addition,  the
National  Association of Insurance  Commissioners  ("NAIC") and state  insurance
regulators,  as part of the  NAIC's  state  insurance  department  accreditation
program,  have re-examined existing laws and regulations,  specifically focusing
on insurance company  investments,  issues relating to the solvency of insurance
companies,  licensing and market  conduct  issues,  interpretations  of existing
laws,  the  development  of  new  laws,  and  the  definition  of  extraordinary
dividends.  In addition,  Congress and certain  federal  agencies have conducted
investigations of the current condition of the insurance  industry in the United
States to  determine  whether  to impose  federal  regulation  of  insurers  and
reinsurers.  From time to time,  Congress  and certain  states  have  considered
various  legislative  proposals which would provide for governmental  earthquake
insurance  coverage.  Legislation  has also from time to time been introduced in
Congress that could result in the federal government's assuming some role in the
regulation of the insurance  industry,  but none is currently  pending.  Neither
Orion nor Guaranty  knows at this time the extent to which such federal or state
legislative or regulatory  initiatives will be adopted,  and no assurance can be
given  that  they  would  not have a  material  adverse  effect  on  Orion's  or
Guaranty's  business.  The  operations of Orion,  Guaranty and their  respective
affiliates are also subject to state  insurance laws and  regulations  requiring
the  licensing  of  insurance  agents,  brokers,   reinsurance   intermediaries,
reinsurance  underwriting  managers,  and managing general agents and regulating
certain  aspects of their  business.  These laws and  regulations  are  intended
primarily for the protection of  policyholders,  rather than shareholders of the
licensed  entities,  and may  include  requirements  for certain  provisions  in
contracts  entered  into  between  Orion,   Guaranty  and  various  insurers  or
reinsurers,  certain record keeping and reporting requirements,  advertising and


                                       28
<PAGE>

business practice rules, and other matters. The businesses of Orion and Guaranty
depend on obtaining and  maintaining  licenses and  approvals  pursuant to which
they operate, as well as compliance with pertinent regulations.  There can be no
assurance  that Orion or  Guaranty  will be able to obtain or  continue,  at any
time,  all such  required  licenses,  approvals or complying  contracts.  In all
jurisdictions,  the applicable  laws and regulations are subject to amendment or
interpretation by regulatory authorities,  and the possibility exists that Orion
or Guaranty may be precluded or  temporarily  suspended from carrying on some or
all of its  activities in a given  jurisdiction.  Such  preclusion or suspension
could have a materially adverse effect on the business and results of operations
of Orion and Guaranty.

         HOLDING  COMPANY  STRUCTURE AND DIVIDENDS.  Both Orion and Guaranty are
defined,  for purposes of state laws, as "insurance  holding companies" and each
is dependent upon the ability of its insurance  subsidiaries to pay dividends to
it (or to the  intermediate  parents  within their  respective  holding  company
structures)  to meet  their  obligations  and cover  their  expenses.  Insurance
companies are limited by law to the payment of dividends out of surplus earnings
above a specified  level,  generally the greater of ten percent of the insurer's
surplus as regards its policyholders or the prior year's net income (in the case
of Colorado,  statutory  net income does not include  realized  capital  gains).
Dividends  in excess  of those  thresholds  are  "extraordinary  dividends"  and
subject to prior regulatory approval.

         FACTORS  AFFECTING  MARKET PRICE OF ORION COMMON STOCK;  FIXED EXCHANGE
RATIO.  Since the market price of Orion Common Stock is subject to  fluctuation,
the market  value of the shares of Orion Common Stock that the holders of Shares
will receive in the Offer may  increase or decrease  before and after the Offer.
The  Exchange  Ratio in the  Offer is fixed at that  number  of  shares of Orion
Common  Stock (not to be less than .1420 or to exceed  .1650) which have a value
determined  as set forth  herein of $6.80 and will not be adjusted  based on any
subsequent  increase or decrease in the price of the Guaranty Shares.  There can
be no assurance that before or after the  consummation  of the Offer,  shares of
Orion  Common  Stock will  continue to trade at prices at or above the prices at
which such  shares have  traded in the past.  The prices at which  Orion  Common
Stock trades after the Offer may be influenced by many factors including,  among
others, the liquidity of the market for Orion Common Stock,  investor and market
analyst perceptions of Orion and the industry in which it operates, the combined
operating  results of Orion and Guaranty,  Orion's dividend policy,  and general
economic and market conditions.

FORWARD-LOOKING STATEMENTS

         This Prospectus contains certain forward-looking  statements within the
meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act
and are subject to the safe harbors created thereby.  These  statements  include
the plans and objectives of management for future  operations,  including  plans
and objectives  relating to the development of Orion's  business in the domestic
and  Canadian  property  and  casualty  markets  and  the  future  operation  of
Guaranty's  business as a provider of specialty  property and casualty insurance
products and services,  principally involving  automobiles.  All forward-looking
statements involve risks and uncertainty,  including,  without limitation, risks
relating to dependence on material contracts,  ability to cede reinsurance risk,
adequacy of loss reserves,  dependence upon key personnel,  ability to integrate


                                       29
<PAGE>

the operations of Orion and Guaranty and achieve expected synergies,  regulatory
and  licensing  requirements,  uncertainties  arising  out of the  trend  toward
consolidation in Guaranty's lines of business and general market  conditions and
competition. The forward-looking statements included herein are based on current
expectations  that involve numerous risks and uncertainties as set forth herein,
the failure of any one of which could materially adversely affect the operations
of Orion and Guaranty.  Orion's and  Guaranty's  plans and  objectives  are also
based on the assumptions  that  competitive  conditions  within the property and
casualty  and  automobile  insurance  business  will not  change  materially  or
adversely  and that  there will be no  material  adverse  change in Orion's  and
Guaranty's operations or business. Assumptions relating to the foregoing involve
judgments with respect, among other things, to future economic,  competitive and
market conditions and future business  decisions,  all of which are difficult or
impossible  to predict  accurately  and many of which are beyond the  control of
Orion and Guaranty.  Although  Orion and Guaranty  believe that the  assumptions
underlying the forward-looking statements are reasonable, any of the assumptions
could  be  inaccurate  and  there  can,  therefore,  be no  assurance  that  the
forward-looking  statements  included  in  this  Prospectus  will  prove  to  be
accurate.   In  light  of  the   significant   uncertainties   inherent  in  the
forward-looking  statements  included herein,  the inclusion of such information
should not be  regarded  as a  representation  by Orion,  Guaranty  or any other
person that the objectives and plans of Orion and Guaranty will be achieved.

FUTURE DIVIDENDS ON ORION STOCK

         Orion declared cash dividends to its  shareholders of $.38 per share in
1994,  $.43 per  share in 1995 and  $.515  per  share in 1996.  Declaration  and
payment of cash dividends has been dependent on Orion's earnings levels, capital
requirements,  financial  condition,  loan covenants,  and other related factors
deemed  relevant  by the Orion  Board.  Orion has  increased  its  common  stock
dividend fourteen times in the last eighteen years.

         Guaranty  declared cash dividends to its shareholders of $.50 per share
each year from 1994 through 1996.  Declaration and payment of cash dividends has
been  dependent  on  its  earnings  levels,   capital  requirements,   financial
condition, loan covenants and other related factors deemed relevant by its Board
of Directors.

                                 SPECIAL FACTORS

BACKGROUND OF THE OFFER

         Since  August  1984,  Orion has had,  directly or through  wholly-owned
subsidiaries,  a substantial  ownership interest in Guaranty.  In November 1988,
Orion,  through wholly-owned  subsidiaries,  increased its ownership of Guaranty
from 49.7% to 100%.  On November 20,  1991,  Orion sold  6,250,000  Shares in an
initial  public  offering  at a net  price  per share of  $13.60,  reducing  its
ownership interest to 49.3% of the then outstanding Shares. Since then, Guaranty
has operated as an independent publicly-traded company.

         On July 18, 1995,  Guaranty  acquired  all the capital  stock of Viking
Insurance  Holdings,  Inc.  ("Viking") for a total consideration of $102,700,000
(subject to certain adjustments). Guaranty financed the acquisition of Viking by
selling  1,550,000 Shares in a European  offering pursuant to Regulation S under
the  Securities  Act,  and  utilizing  a portion  of a new  $110,000,000  credit
facility  from a group of  lending  banks.  At that  time,  certain  of  Orion's
wholly-owned subsidiaries held $20,896,000 of Guaranty's subordinated promissory
notes due 2003 (the "2003  Notes")  which had been issued in November  1991.  To
facilitate Guaranty's  acquisition of Viking, the entire principal amount of the
2003 Notes was  converted  in July and  October  1995 into  1,326,128  Shares at
$15.76 per share,  the same net price  received by Guaranty in its  Regulation S
offering.  The  conversion  of the 2003  Notes  restored  Orion to its  previous
ownership level in Guaranty of slightly less than 50% of the outstanding  Shares
following  the  increase  in the  number of  Shares  resulting  from  Guaranty's
Regulation  S  offering.   From  November   1995  through  March  1996,   Design
Professionals Insurance Company, a wholly-owned subsidiary of Orion, acquired an
additional 80,000 Shares in open market purchases.

         In December 1995 and February 1996, representatives of companies in the
insurance  industry  expressed an interest to the late Mr. Alan R. Gruber,  then
the Chairman and Chief  Executive  Officer of Orion, in acquiring from Orion its
Shares in connection with a possible  acquisition of Guaranty.  In each of these
cases, such companies  subsequently indicated that their managements had decided
to  pursue  other  opportunities.  No price  was  discussed  in any case for the
Shares,  and no offer was made.  In March 1996,  a financial  intermediary  told
Orion that he had proposed to a  third-party  entity the possible  purchase from
Orion of its Shares in  connection  with a possible  purchase of  Guaranty.  The
financial  intermediary  was not retained by Orion to effect such a  transaction
and Orion has no  information to the effect that he was retained to do so by the
third party.  Orion had no further contact and received no offer  concerning the
proposal.

         On May 8, 1996, Orion and certain of its wholly-owned subsidiaries (the
"Subsidiaries")  commenced a tender offer for up to 4,600,000  Shares (the "1996
Tender Offer"), a number which would bring Orion's ownership to more than 80% of
the outstanding Shares and allow Orion to file a consolidated federal income tax
return which includes  Guaranty.  Prior to consummation of the 1996 Tender Offer
and in  connection  with it,  a 1991  Shareholder  Agreement  among  Orion,  its
Subsidiaries and Guaranty was amended (as amended, the "Shareholder Agreement").
Orion  and the  Subsidiaries  agreed  not to  purchase,  prior to July 1,  1999,
additional  Shares (if after giving  effect to such purchase they would own more
than 81% of the  outstanding  Shares) other than pursuant to an offer  involving


                                       31
<PAGE>

consideration  equal to at least  $18.50  per Share and made for all  Shares not
held by them,  such offer to be conditioned  upon the  acceptance  thereof by at
least a majority  of the Shares then  outstanding  and not held by Orion and its
Subsidiaries.  On July 2, 1996, Orion and the Subsidiaries  completed the Tender
Offer for 4,600,000 Shares.

         On July 2, 1996, Orion also signed a Memorandum of  Understanding  with
respect to the settlement and dismissal of three lawsuits which had been brought
as a result of the 1996 Tender Offer. Pursuant to the terms of the Memorandum of
Understanding,  all pending  litigation was to be terminated and Orion confirmed
the  undertaking  with respect to the purchase of  additional  Shares  described
above, which it had made while the 1996 Tender Offer was pending.

         On July 17, 1996, Orion purchased,  for $14.50 per Share, an additional
120,000 Shares,  which together with Shares  purchased in the 1996 Tender Offer,
increased Orion's aggregate  ownership of Shares to approximately  81.0%.  Since
July 17, 1996, Orion and its subsidiaries have not purchased any Shares.

         Orion  and  its  Subsidiaries,  beneficially  own,  in  the  aggregate,
12,129,942 Shares. Set forth below is the number of Shares held by Orion and its
Subsidiaries, respectively, as of the date of this Prospectus:

*    Based on the number of shares  reported  by  Guaranty in its June 1997 Form
     10-Q to be outstanding as of August 4, 1997.

         Although  each of  Orion's  Subsidiaries  has  sole  power  to vote and
dispose of its Shares and makes its own investment decisions, Orion is deemed by
its direct or indirect voting control of the  Subsidiaries to be able ultimately
to direct the  acquisition,  voting and  disposition  of the Shares  held by its
Subsidiaries.

         By mid-1997,  senior management of Orion determined that if Guaranty is
to be a significant factor in the nonstandard personal auto insurance market, it
would be desirable for it to expand its base of business. That conclusion was in
part based on the consolidation of the nonstandard auto insurance  business that
was taking place during the first and second  quarters of 1997.  To some extent,
Guaranty itself has the capital capacity to expand its business base by internal


                                       32
<PAGE>

and external growth but certain  strategic  alternatives  being considered by it
will likely require additional capital if they are to be accomplished. Orion has
concluded that such additional capital support can be more efficiently furnished
if Guaranty were to become a wholly-owned subsidiary of Orion.

         In June, 1997, during a discussion of Guaranty's strategic alternatives
among W. Marston Becker, Chairman and Chief Executive Officer of Orion, James R.
Pouliot,  President  and Chief  Executive  Officer of  Guaranty,  and Michael L.
Pautler,  Senior  Vice  President  of Finance and  Treasurer  of  Guaranty,  the
possible advantage of a closer consolidation was raised but not discussed in any
detail.

         On July 8, 1997, an Executive  Committee  meeting of the Orion Board of
Directors was held to explore the various  aspects of the potential  acquisition
by Orion of the Shares it does not own. The Executive  Committee  authorized Mr.
Becker to open a dialogue  with  Guaranty  to discuss  the  potential  of such a
transaction. On that same day, Mr. Becker telephoned Mr. Pouliot to continue the
discussion of the strategic  alternatives of Guaranty.  During that meeting, Mr.
Becker  expressed  the view that  consideration  might be given to having  Orion
acquire the remaining interest in Guaranty,  not already owned by Orion, through
a merger or similar transaction. Based on the closing sales price of $23.9375 of
Shares on July 8, 1997,  Mr.  Becker  suggested a possible  price of $26.00.  He
further  suggested  that a merger in which stock of Orion would be exchanged for
the  Shares not  already  owned by Orion on an agreed  ratio  seemed to Orion to
produce  the most  favorable  after-tax  result to  individual  shareholders  of
Guaranty (noting that certain institutional shareholders might be less concerned
with the form of  consideration).  He further  stated  that among the holders of
Shares, there were a significant number of holders who were also shareholders of
Orion,  concluding  that since those  persons  had  already  chosen to invest in
Orion,  they presumably would be well disposed to continuing their investment in
Guaranty on an  indirect  basis by  increasing  their  holdings of Orion  Common
Stock.  He  suggested  that before any  discussions  took place  concerning  the
desirability of a merger of Guaranty, the financial adviser of Orion meet with a
designated  financial  adviser to Guaranty to discuss the relative  valuation of
the two entities.  He further  suggested that any financial  adviser retained by
Guaranty  report to the directors of Guaranty who are not employees or directors
of Orion.  Subsequently,  Orion was informed that Guaranty had retained the firm
of Salomon Brothers Inc ("Salomon") to represent Guaranty in such discussions.

         During  the  months  of July  and  August  1997,  Salomon  and  Orion's
financial adviser,  Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"),
conducted  due  diligence   reviews  at  Guaranty  and  Orion  and  had  several
conversations  concerning  valuation  principles  which  might be  relevant to a
merger of Guaranty into a subsidiary of Orion.  No agreement was reached by them
as to  the  valuation  of  the  Shares  not  already  owned  by  Orion  and  its
Subsidiaries or even as to a mutually-agreed  range of values. Orion was advised
that  further  due  diligence  and  analysis  would be  required  by  Guaranty's
financial adviser.

         On September 2, 1997, an Executive Committee meeting of the Orion Board
of Directors was held to discuss the status of the discussions between Orion and


                                       33
<PAGE>

Guaranty.  The Executive Committee authorized Mr. Becker to send a letter to the
Guaranty  Board of Directors to propose a meeting to discuss the potential for a
transaction.

         On  September  4,  1997,  Mr.  Becker  sent a  letter  to the  Board of
Directors  of  Guaranty  and  requested  that a special  meeting of the Board of
Directors  of  Guaranty  be held  following  a regular  meeting  of the Board of
Directors of Orion which was to be held in Colorado on September 12. The purpose
of the meeting was to discuss with the entire Guaranty Board why Mr. Becker felt
the  combination of the two companies was  strategically  important for Guaranty
and the results, from his perspective,  of the discussions which had taken place
since July between the companies' financial advisers.  In the letter, Mr. Becker
stated he would be  prepared  to suggest to the Orion  Board of  Directors  that
Orion acquire, most likely through a merger, the remaining Shares it did not own
for a value of $30.25 per share (partially cash and partially stock).

         On September 12, 1997,  separate meetings of the Boards of Directors of
Orion and of Guaranty  were held at the  headquarters  of Guaranty in Englewood,
Colorado.  At the Orion meeting, the Board of Directors authorized Mr. Becker to
discuss  with the Board of Directors of Guaranty the work which had been done by
its financial advisers.  Anticipating that the financial adviser of Guaranty had
informed the independent directors of Guaranty of its conclusions concerning its
valuation of the Shares not already owned by Orion and its Subsidiaries, Orion's
Board of  Directors  authorized  the  Executive  Committee of the Orion Board to
formulate  an offer to  Guaranty  if it  appeared  that  there  was  substantial
agreement with the  recommendations to Guaranty's  independent  directors by its
financial adviser.

         At the meeting on  September  12 of the  Guaranty  Board of  Directors,
Orion was informed that the  independent  directors of Guaranty had not formally
met with their  financial  adviser and had not reached any  conclusion as to the
value  of  the  Shares  not  already  owned  by  Orion  and  its   Subsidiaries.
Nonetheless,  Mr. Becker presented to the Guaranty Board of Directors data which
had been  developed  by  Orion  and its  financial  adviser  as to the  value of
Guaranty and as to the form of transaction and form of consideration which Orion
believed  would  be  most  advantageous  to the  shareholders  of  Guaranty.  He
indicated  to the Board of Guaranty  that he would be  prepared  to  recommend a
price of $30.25 per Share  (partially cash and partially stock) to Orion's Board
of Directors  and was informed that the  independent  directors of Guaranty were
not at that time in a position to consider an offer without  further advice from
Guaranty's financial adviser.  Orion was informed that the independent directors
of Guaranty would organize themselves to evaluate the proposal.

         On September  15, 1997,  one of the  independent  directors of Guaranty
telephoned  Mr. Becker and informed him that the  independent  directors had met
with their  financial  adviser and discussed  with their  financial  adviser its
evaluation  study. He further stated that the financial adviser wished to review
the results of  Guaranty's  operations  since the  adviser's  last  meeting with
senior management. Finally, he suggested the desirability of additional meetings
involving Mr. Becker and one or more of Guaranty's independent directors.



                                       34
<PAGE>

         On September 16, 1997,  Mr. Becker was asked,  as Chairman of Guaranty,
to  convene a  meeting  of its  Executive  Committee  at which  the  independent
directors could be formally designated as a special committee.  That meeting was
called  and a Special  Committee  was  appointed  with  Dennis  J.  Lacey as its
Chairman;  the other  director-members  are Tucker H. Adams, M. Ann Padilla, and
Richard R. Thomas.  Mr. Becker was then asked, as the Chairman of Orion, to meet
with Mr.  Lacey,  and the legal and  financial  advisers  of both  Orion and the
independent directors, to discuss further a potential transaction and to attempt
to reach  agreement on value.  That meeting took place on September 17, 1997, in
Englewood, Colorado.

         At the September 17 meeting,  a representative of Guaranty's  financial
adviser presented an analysis of its valuation  approach but noted that his firm
was not yet in a  position  to  render  an  opinion  as to the  fairness  of any
particular  price. The  representatives  of Orion  concluded,  based on exhibits
prepared  by  and  remarks  made  by  Guaranty's  advisers,   that  a  price  of
approximately  $34.00  was a fair  price  upon  which to base an  offer  for the
Shares. The Special Committee suggested a price of $36.00, but at the conclusion
of discussions, Mr. Becker proposed an offer of $34.00 per Share, payable 80% in
cash and 20% in Orion Common Stock with a formula designed to adjust for changes
in excess of approximately 7 1/2% in the closing market price on September 17 of
Orion Common Stock,  subsequent to September 17 and prior to the exchange  date,
and with  provision for  termination  rights if the market price of Orion Common
Stock should rise or fall by approximately 15% or more. Orion's advisers further
recommended  that this  transaction  be  accomplished  by a tender offer for all
Shares not owned by Orion, followed by a merger in which any Shares not properly
tendered could be acquired.

         During the evening of September 17, Mr. Lacey telephoned Mr. Becker and
informed  him  that  the  Special  Committee  was  not in a  position  to make a
recommendation  concerning  the  offer  which  had  been  extended.  Mr.  Becker
indicated to him that Orion's opinion was that the discussion process would best
be served by making a specific  proposal  containing those elements which seemed
to Orion to be fair to the  shareholders  of Guaranty and to recognize fully the
value of the  outstanding  Shares  not owned by Orion and its  Subsidiaries.  On
September  18, Orion issued a press  release  announcing  that it would make the
Offer directly to the shareholders of Guaranty so that each Guaranty shareholder
could make his or her own judgment as to whether to accept Orion's Offer.

     GUARANTY BOARD  COMPOSITION;  ORION  NOMINEES.  Messrs.  W. Marston Becker,
Chairman and Chief  Executive  Officer of Orion,  Vincent T. Papa,  Chairman and
Chief Executive  Officer of Wm. H. McGee & Co., Inc., a wholly-owned  subsidiary
of Orion,  and  William J.  Shepherd,  a director of Orion,  currently  serve as
Orion's  designated  directors  on  Guaranty's  Board.  Mr.  Robert B.  Sanborn,
formerly the  President of Orion and formerly an Orion  designee on the Guaranty
Board,  and now a senior  consultant of Orion, was asked by Guaranty to continue
as a director of Guaranty  following his  retirement as President of Orion.  Mr.
Sanborn is currently a director of Orion but is not an Orion-designated director
of Guaranty.  Mr. Sanborn receives the regular fees and other benefits  provided
to all  non-employee  directors  of Guaranty.  Mr.  Roger B. Ware  resigned as a
member of Orion's Board of Directors as of September  11, 1997. He  subsequently
advised  Orion  that his  reason was to avoid any  appearance  of a conflict  of
interest  during the Board  discussions  scheduled  for  September  12. Mr. Ware


                                       35
<PAGE>

continues  as a  director  of  Guaranty  and is,  according  to the  1997  Proxy
Statement of  Guaranty,  the  beneficial  owner of 92,071  Shares.  Mr. Ware was
formerly the President and Chief Executive Officer of Guaranty.  Messrs. Sanborn
and Shepherd are two of the four members of Guaranty's  Compensation  Committee.
Mr.  Shepherd  is the  Chairman  of  both  Orion's  Compensation  Committee  and
Guaranty's Compensation Committee.

         The  Shareholders  Agreement  provides  that so long  as  Orion  or its
subsidiaries  beneficially  own  in the  aggregate  30% or  more  of the  voting
securities of Guaranty, Orion will continue to have the right to designate three
nominees to  Guaranty's  Board (one of whom will be the  Chairman of the Board),
and so  long  as  Orion  or its  subsidiaries  beneficially  own  20% or more of
Guaranty's  voting  securities,  Orion  will  have the  right to  designate  two
nominees.  Orion may also require that Guaranty's Compensation Committee include
Orion's nominees to Guaranty's Board.  None of Orion's nominees,  other than Mr.
Shepherd, receives any compensation from Guaranty, including any retainer fee or
attendance fee for his services,  except for travel  expenses in connection with
attendance at directors' meetings.

         Orion's  nominees  intend,  in all  deliberations of the Guaranty Board
with  respect  to the  Offer,  to be guided by the  advice of legal  counsel  to
Guaranty as to when and to what extent they should be present at and participate
in  Board   discussions.   They  intend,   however,   that  all   decisions  and
recommendations of the Guaranty Board with respect to the Offer be made or taken
by action of directors of Guaranty who are not officers or directors of Orion.

         The Guaranty  Board has 6 members who are not  designees of or officers
or  directors of Orion.  They are Messrs.  Lacey,  Pouliot,  Thomas and Ware and
Messes. Adams and Padilla.

FAIRNESS OF THE OFFER

         Orion  believes that the Offer is fair to the  unaffiliated  holders of
Shares  to whom it is  directed.  In  concluding  that the Offer is fair to such
shareholders of Guaranty,  Orion has considered,  among other matters,  (i) that
the $34.00 per Share price  represents  a premium of 4.6% over the closing  sale
price of $32.50 per Share as reported by the NYSE on September 17 1997, the date
prior to the issuance of the press release announcing Orion's intent to make the
Offer (the "Press Release Date"), a 17.7% premium over the closing sale price of
$28.875 on September 10, one week prior to the Press  Release Date,  and a 19.6%
premium over the closing sale price of $28.4375 on August 18, one month prior to
the Press  Release  Date;  (ii) that the $34.00  per Share  price  represents  a
premium of 40.2% over the closing sale price of $24.25 on July 7, 1997,  the day
prior to the  commencement of discussions  with Guaranty;  (iii) that the $34.00
per Share price  represents  a multiple of 1.97x  Guaranty's  net book value per
share of $17.27  as of June 30,  1997 and a  multiple  of 2.27x  Guaranty's  net
tangible  book value per share of $15.01 as of June 30,  1997 (Orion has made no
analysis of the  liquidation  value of Guaranty and  therefore  has no basis for
expressing  an  opinion  as to the  comparison  of the  Offer  Consideration  to
liquidation  value);  (iv) historical market prices of the Shares since Guaranty
became a public company, including the average daily closing stock price for the
12 months ended June 30, 1997 of $17.34;  (v) Orion's  evaluation of competitive
trends and other  conditions  in the markets in which  Guaranty  operates;  (vi)


                                       36
<PAGE>

Orion's  knowledge of the business,  historical  results of  operations  and the
properties,  assets  and  earnings  of  Guaranty  and its recent  financial  and
operating performance;  (vii) the $18.50 per Share purchase price that Orion and
its  wholly-owned  subsidiaries  paid in July 1996 to purchase  up to  4,600,000
shares of Guaranty  pursuant to the 1996 Tender  Offer and the $14.50  price per
Share  paid by Orion  for an  additional  120,000  Shares  on July  17,  1996 in
open-market  purchases;  (viii) the plans of  Guaranty  to expand  its  business
through internal growth and acquisition and the ability of Guaranty to carry out
its plans with assets on hand and cash expected to be generated from operations,
and (ix) the fact that Orion already  beneficially owns approximately 81% of the
outstanding  Shares,  making any  "control"  premium  for the  non-Orion  Shares
inapplicable.

         The foregoing  discussion of the information and factors  considered by
Orion is not intended to be  exhaustive.  In view of the wide variety of factors
considered in connection with the  determination of the Offer  Consideration and
the  evaluation of the fairness of the Offer,  Orion did not find it practicable
to, and did not, quantify or otherwise attempt to assign relative weights to the
foregoing  factors or determine  that any factor was of  particular  importance.
Rather,  Orion  viewed  its  position  as  being  based on the  totality  of the
information presented to and considered by it. On balance, however, Orion viewed
the factors set forth in items (i) through (iii),  (v), (vi), (viii) and (ix) as
very influential to its decision and the remainder of lesser significance.

         Orion has not  obtained,  or sought to obtain,  any report,  opinion or
appraisal from an outside party,  including,  without limitation,  an investment
banker's  opinion as to the  fairness  of the Offer to  unaffiliated  holders of
Shares.  Orion's  Board of  Directors  has received a report from DLJ on various
techniques  that  might be  utilized  to  assist  in  determining  the price and
structure of a possible transaction.

REASONS FOR THE OFFER; PURPOSE AND STRUCTURE OF THE
TRANSACTION; PLANS AFTER THE OFFER; EFFECTS OF THE OFFER

         Orion   believes  it  can  provide  to  Guaranty,   as  a  wholly-owned
subsidiary,  access to capital in amounts and on terms that may not be available
to Guaranty as an independent  entity.  In order to place Guaranty in a position
to carry out a variety  of  potential  strategic  alternatives  on a timely  and
adequately-financed basis, and to protect the significant investment which Orion
presently  has in Guaranty,  Orion has  determined to seek to acquire the Shares
which  it  does  not  presently  own.  To the  extent  that  any  Shares  remain
outstanding  following  completion  of the  present  Offer,  Orion  will seek to
acquire such Shares  either in a merger or in a subsequent  tender offer on such
terms  and  conditions  as may seem  appropriate  at the time,  which  terms and
conditions  may be the same as or different from the terms and conditions of the
Offer.

         Orion presently  intends,  as soon as practicable after consummation of
the Offer, to seek to have Guaranty effect a merger with and into a wholly-owned
subsidiary  of Orion.  If Orion,  together with its  wholly-owned  subsidiaries,
following consummation of the Offer, owns 90% or more of the outstanding Shares,
Orion may be able to effect such a merger of Guaranty without the consent of the
Board of Directors or shareholders of Guaranty  pursuant to Section 7-111-104 of
the Colorado  Business  Corporation  Act. In the event that Orion obtains all of


                                       37
<PAGE>

the Tender  Shares  pursuant to the Offer and/or a merger or  otherwise,  former
holders  of the  Shares  would as a  result  acquire  approximately  1.6% of the
outstanding  shares  of Orion  Common  Stock,  based  on the  number  of  shares
outstanding on September 1, 1997. Orion believes that Guaranty  shareholders who
tender their Shares  pursuant to the Offer would have the  opportunity to retain
an indirect  equity  interest in the  business of  Guaranty,  as a  wholly-owned
subsidiary of Orion,  through their equity ownership of Orion, a larger,  better
capitalized company.  Orion understands that directors and executive officers of
Orion who beneficially own Shares will tender them for exchange  pursuant to the
Offer.

         For information  about certain  possible effects of the Offer, see "The
Offer -- Effect of the Offer on the  Market  for the  Shares;  Quotation  on the
NYSE;  Registration  Under the Exchange  Act," "-- Margin  Regulations"  and "--
Certain Legal Matters."

         Except as set forth above in this Prospectus, Orion has no present plan
or proposals which relate to or would result in (i) an  extraordinary  corporate
transaction,  such as a merger, reorganization or liquidation of Guaranty or any
of its  subsidiaries,  (ii) a sale or transfer of a material amount of assets of
Guaranty or any of it  subsidiaries,  (iii) any material  changes in  Guaranty's
corporate  structure,  business or  composition  of its management or personnel;
(iv) any material change in the present capitalization,  dividend rate or policy
or indebtedness of Guaranty, (v) any change in the present board of directors of
Guaranty,  including,  but not  limited  to, any plan or  proposal to change the
number or term of existing directors,  to fill any existing vacancy on the board
or to change any term of the employment contract of any executive officer;  (vi)
a class  of  equity  securities  of  Guaranty  being  delisted  from a  national
securities  exchange or ceasing to be authorized to be quoted on an inter-dealer
quotation  system of a registered  national  securities  association or becoming
eligible for  termination or  registration  pursuant to Section  12(g)(4) of the
Exchange Act or the suspension of Guaranty's obligation to file reports pursuant
to Section 15(d) of the Exchange Act.

                                    THE OFFER

THE EXCHANGE RATIO

         The term  "Exchange  Ratio" means the quotient  (rounded to the nearest
1/100,000) determined by dividing $6.80 by the average of the high and low sales
prices  of Orion  Common  Stock  (as  reported  on NYSE  Composite  Transactions
reporting  system as published in The Wall Street  Journal or, if not  published
therein, in another authoritative source) (the "Orion Average Price") on each of
the ten  consecutive  trading days ending with the fifth trading day immediately
preceding the Expiration  Date. The Exchange Ratio will be adjusted if the Orion
Average  Price  deviates  by more than  approximately  7.5% from  $44.5625,  the
closing  price of Orion Common Stock on September 17, 1997. If the Orion Average
Price is greater  than  $47.90,  the dollar  value of Orion  Common  Stock to be
received  pursuant to the Offer will  increase  from $6.80 to a maximum of $7.28
should the Average  Orion Price rise to $51.25.  If the Orion  Average  Price is


                                       38
<PAGE>

less than $41.22 the dollar value of Orion Common Stock to be received  pursuant
to the Offer will  decrease to a minimum of $6.25 should the Orion Average Price
fall to $37.88. If the Orion Average Price should be greater than $51.25 or less
than $37.88,  Orion may in its sole discretion  refuse to accept Shares tendered
for exchange.  On September 19, 1997, the closing price of Orion Common Stock on
the NYSE was  $44.00.  If that price  were to be the Orion  Average  Price,  the
Exchange Ratio would be 0.1545 Shares of Orion Common Stock for each Share.  The
Exchange  Ratio  will  change  as the  market  price of the Orion  Common  Stock
changes. The actual Orion Average Price and Exchange Ratio will be calculated as
of the fifth trading day immediately  prior to the Expiration Date, as described
above and a press release will be issued  announcing  the actual  Exchange Ratio
prior to the opening of the fourth trading day prior to the Expiration  Date (as
it may be extended from time to time).

TERMS OF THE OFFER

         GENERAL;  EXPIRATION  DATE.  Orion  hereby  offers,  upon the terms and
subject  to the  conditions  set  forth  herein  and in the  related  Letter  of
Transmittal,  to exchange the Offer  Consideration  for each  outstanding  Share
(other  than those  owned by Orion or its  wholly-owned  subsidiaries),  validly
tendered prior to the Expiration Date (as hereinafter  defined) and not properly
withdrawn.  The Offer  Consideration  is  $27.20  net in cash  and,  subject  to
adjustment  as set  forth  herein,  $6.80  of  Orion  Common  Stock  per  Share,
calculated  at the  Exchange  Ratio.  The term  "Expiration  Date"  means  12:00
Midnight, New York City time, on ______, 1997, unless and until Orion shall have
extended the period of time for which the Offer is open, in which event the term
"Expiration  Date" shall mean the latest time and date on which the Offer, as so
extended by Orion, shall expire. See "-- The Exchange Ratio" above. On September
19, 1997,  the closing  price of Orion  Common Stock on the NYSE was $44.00.  If
that price were to be the Orion  Average  Price,  the  Exchange  Ratio  would be
0.1545  shares of Orion  Common  Stock for each Share.  A press  release will be
issued  announcing the actual  Exchange Ratio prior to the opening of the fourth
trading day prior to the  Expiration  Date (as it may be  extended  from time to
time). Cash will be paid in lieu of fractional shares of Orion Common Stock; see
"-- Cash in Lieu of Fractional Shares of Orion Common Stock."

         Tendering  shareholders  will not be  obligated  to pay any  charges or
expenses of the Exchange Agent.  Except as set forth in the  Instructions to the
Letter of Transmittal,  any transfer taxes on the exchange of Shares pursuant to
the Offer will be paid by or on behalf of Orion.

         Orion's  obligation  to  exchange  the Offer  Consideration  for Shares
pursuant to the Offer is subject to the Minimum Share Condition, the Rights Plan
Condition,  the  Regulatory  Approval  Condition  and the  Orion  Average  Price
Condition (in each case as defined on the cover page of this Prospectus) and the
other conditions set forth below under "-Certain Conditions of the Offer."

         According to  Guaranty's  Quarterly  Report on Form 10-Q for the period
ended  June 30,  1997,  as of August  4,  1997,  there  were  15,038,433  Shares
outstanding. Orion, directly or through wholly-owned beneficiaries, beneficially
owns 12,129,942 Shares or approximately 81% of the outstanding  Shares as of the
date of this Prospectus.

         Orion  expressly  reserves the right, in its sole  discretion,  for any
reason,  at any time or from time to time,  and regardless of whether or not any


                                       39
<PAGE>

of the  events set forth in "--  Certain  Conditions  of the  Offer"  shall have
occurred or shall have been determined by Orion to have occurred,  to extend the
period of time during  which the Offer is open by giving oral or written  notice
of such  extension  to the  Exchange  Agent and by making a public  announcement
thereof.  During any such  extension,  all  Shares  previously  tendered  may be
withdrawn as set forth below under "--Withdrawal  Rights" below. There can be no
assurance  that Orion will  exercise  its right to extend the Offer.  Subject to
applicable  rules of the SEC, Orion  expressly  reserves the right,  in its sole
discretion,  at any time or from time to time,  and regardless of whether or not
any of the events set forth in "-- Certain  Conditions  of the Offer" shall have
occurred or shall have been determined by Orion to have occurred, to increase or
decrease the price per Share  payable in the Offer or to make any other  changes
in the terms and  conditions  of the Offer by giving  written or oral  notice of
such  amendment  to the  Exchange  Agent.  The rights  reserved to Orion in this
paragraph are in addition to Orion's  right to terminate  the Offer  pursuant to
"--Certain  Conditions  of the  Offer."  If  Orion  shall  decide,  in its  sole
discretion,  to increase or decrease the  consideration  offered in the Offer to
holders  of  Shares  and,  at the  time  that  notice  of such  change  is first
published, sent or given to holders of Shares in the manner specified below, the
Offer is scheduled to expire at any time earlier than the expiration of a period
ending on the tenth business day from, and including,  the date that such notice
is first so published,  sent or given,  then the Offer will be extended at least
until the  expiration  of such period of ten  business  days.  If,  prior to the
Expiration  Date, Orion shall increase the  consideration  offered to holders of
Shares pursuant to the Offer, such increased  consideration shall be paid to all
holders  whose  Shares are  accepted  for  exchange  pursuant to the Offer.  For
purposes  of the Offer,  a  "business  day" means any day other than a Saturday,
Sunday or federal  holiday,  and  consists  of the time  period  from 12:01 a.m.
through 12:00 midnight, New York City time.

         The SEC has announced that under its  interpretation  of Rules 14d-4(c)
and 14d-6(d)  under the  Exchange Act material  changes in the terms of a tender
offer or  information  concerning  the tender  offer may require that the tender
offer be  extended  for a  sufficient  period of time to allow  shareholders  to
consider  such material  changes or  information  in deciding  whether or not to
tender,  withdraw or hold their  shares.  Orion  confirms  that if Orion makes a
material  change  in the terms of the Offer or the  information  concerning  the
Offer, or if it waives a material  condition to the Offer, Orion will extend the
Offer and disseminate  additional  tender offer materials to the extent required
by Rules 14d-4(c) and 14d-6(d)  promulgated  under the Exchange Act. The minimum
period during which an offer must remain open following  material changes in the
terms of the offer or information  concerning the offer,  other than a change in
price or a change in percentage of securities sought, will depend upon the facts
and  circumstances,   including  the  relative   materiality  of  the  terms  or
information  changed.  With respect to a change in price or change in percentage
of securities sought, a minimum ten business day period is generally required to
allow for adequate dissemination to shareholders and investor response.

         The SEC has stated that in its view an offer  should  remain open for a
minimum  of five  business  days  from  the  date a  material  change  is  first
published,  sent or given to shareholders to whom the offer is made, and that if
material  changes  are made with  respect to  information  that  approaches  the
significance  of price and share  levels,  a minimum of ten business days may be
required to allow for adequate dissemination and investor response.



                                       40
<PAGE>

         Orion  does not expect  this to be the case,  but should for any reason
the Rights be deemed to be  exercisable,  and the Rights Plan  Condition  not be
invoked by Orion, Guaranty shareholders will be required to tender one Right for
each Share  tendered to effect a valid  tender of such  Shares.  See "-- Certain
Conditions of the Offer" and "-- Certain Legal Matters -- (f) Guaranty's Charter
Documents; The Shareholder Agreement; the Rights Plan and Other Matters."

         Subject  to the  applicable  rules and  regulations  of the SEC,  Orion
expressly reserves the right, in its sole discretion,  at any time, or from time
to time,  (i) to  delay  acceptance  for  payment  or  payment  for any  Shares,
regardless of whether such Shares were theretofore  accepted for payment,  or to
terminate  the Offer and not accept for  exchange or exchange for any Shares not
theretofore  accepted for exchange or exchanged  for, upon the occurrence of any
of the events specified in "--Certain Conditions of the Offer" by giving oral or
written  notice of such delay in  acceptance  or payment or  termination  to the
Exchange  Agent  and  (ii) at any  time,  or from  time to time,  to  waive  any
condition  (except the Minimum Share  Condition) or otherwise amend the Offer in
any  respect.  Any  extension  of the Offer,  delay in  acceptance  or  payment,
termination  or  amendment  of  the  Offer  will  be  followed  as  promptly  as
practicable by public announcement  thereof, such announcement in the case of an
extension to be issued no later than 9:00 A.M.,  New York City time, on the next
business day after the previously  scheduled Expiration Date, in accordance with
the public  announcement  requirements  of Rule 14d-4(c)  promulgated  under the
Exchange Act.  Without limiting the manner in which Orion may choose to make any
public  announcement,  Orion shall have no  obligation,  and currently  does not
intend,  except  as  required  by  law,  to  publish,   advertise  or  otherwise
communicate any such public  announcement other than by issuing a release to the
Dow Jones News Service and making any appropriate filing with the SEC.

         Orion  reserves the right to transfer or assign,  in whole or from time
to time in part, to one or more of the its  wholly-owned  subsidiaries the right
to  purchase  Shares  tendered  pursuant to the Offer,  but no such  transfer or
assignment  will relieve Orion of its  obligations  under the Offer or prejudice
the  rights  of  tendering  shareholders,  upon the  terms  and  subject  to the
conditions of the Offer,  to exchange  Shares validly  tendered and accepted for
exchange pursuant to the Offer for shares of Orion Common Stock.

         A request is being made of  Guaranty  pursuant  to Rule 14d-5 under the
Exchange Act for the use of its shareholder lists and security position listings
for the purpose of communications  with Guaranty  shareholders and disseminating
the Offer to holders of Shares.  A final  Prospectus  and the related  Letter of
Transmittal  and other  relevant  materials  will be mailed to record holders of
Shares on [the date of this Prospectus] and will be furnished to brokers,  banks
and similar persons whose names,  or the names of whose nominees,  appear on the
shareholder  lists or,  if  applicable,  who are  listed  as  participants  in a
clearing  agency's  security  position  listing for  subsequent  transmittal  to
beneficial owners of Shares.

         ACCEPTANCE  FOR PAYMENT  AND  PAYMENT  FOR  SHARES.  Upon the terms and
subject to the conditions of the Offer,  including,  if the Offer is extended or
amended, the terms and conditions of any such extension or amendment, Orion will
accept for exchange (and thereby  purchase)  Shares (and Rights,  if applicable)
validly  tendered and not properly  withdrawn in accordance  with the provisions


                                       41
<PAGE>

set forth below under "--  Withdrawal  Rights" below  (including  Shares validly
tendered and not withdrawn  during any  extension of the Offer,  if the Offer is
extended,  upon the terms and subject to the conditions of such  extension),  as
promptly as practicable  after the Expiration  Date. THE OFFER IS CONDITIONED ON
THE MINIMUM NUMBER OF SHARES BEING TENDERED.  See "-- Certain  Conditions of the
Offer." Orion expressly reserves the right to delay acceptance for payment of or
payment  for  Shares in order to comply in whole or in part with any  applicable
law or  regulation  as set forth in "--  Certain  Conditions  of the  Offer" and
referred to as the  Regulatory  Approval  Condition but intends either to extend
the  Expiration  Date,  or to terminate  the Offer if it should  appear that the
Regulatory Approval Condition will delay for more than five (5) days the payment
for shares accepted for payment.  See "-- Certain  Conditions of the Offer." The
reservation by Orion of the right to delay acceptance for payment or payment for
Shares  is  subject  to the  provisions  of  applicable  law  under  Rule  14e-1
promulgated  under the Exchange  Act,  which  require that the purchaser pay the
consideration  offered  or  return  the  shares  deposited  by or on  behalf  of
shareholders promptly after termination or withdrawal of the Offer.

         In all cases,  exchange of Shares (and Rights, if applicable)  tendered
and accepted  for exchange  pursuant to the Offer will be made only after timely
receipt  by the  Exchange  Agent of  certificates  for  such  Share,  or  timely
confirmation (a "Book-Entry Confirmation") of book-entry transfer of such Shares
into the Exchange Agent's account at The Depository Trust Company ("DTC") or The
Philadelphia  Depository Trust Company ("PDTC") (sometimes  hereinafter referred
to  individually  as a "Book-Entry  Transfer  Facility" and  collectively as the
"Book-Entry  Transfer  Facilities")  pursuant  to the  procedure  set  forth  in
"Procedures  for Accepting the Offer and Tendering  Shares," and, in either such
case,  timely  receipt by the Exchange  Agent of a properly  completed  and duly
executed  Letter  of  Transmittal  (or  facsimile  thereof)  with  any  required
signature  guarantees or Agent's  Message (as defined under "--  Procedures  for
Accepting the Offer and Tendering Shares") and any other required documents.

         For purposes of the Offer,  Orion shall be deemed to have  accepted for
exchange Shares (and Rights,  if applicable)  validly tendered and not withdrawn
when, as and if Orion gives oral or written  notice to the Exchange Agent of its
acceptance of the tender of such Shares for exchange. Upon the terms and subject
to the conditions of the Offer,  delivery of the Offer Consideration and cash in
lieu of fractional  shares of Orion Common  Stock,  will in all cases be made by
the Exchange  Agent,  which will act as an agent for the tendering  shareholders
for the purpose of receiving from Orion and transmitting such Orion Common Stock
and cash to tendering shareholders. Under no circumstances will interest be paid
on the purchase price by Orion by reason of any delay in making such payment.

         If any tendered  Shares are not  accepted for exchange  pursuant to the
Offer for any reason,  or if certificates  submitted  represent more Shares than
are  tendered,  certificates  for such Shares not  exchanged or tendered will be
returned without expense to the tendering shareholder (or, in the case of Shares
delivered  by  book-entry  transfer  into  the  Exchange  Agent's  account  at a
Book-Entry  Transfer  Facility  pursuant  to the  procedures  set  forth  in "--
Procedures  for Accepting  the Offer and Tendering  Shares," such Shares will be
credited to an account  maintained  at such  Book-Entry  Transfer  Facility)  as
promptly as practicable following the expiration or termination of the Offer. If
for any reason  whatsoever  (whether before or after the acceptance for exchange


                                       42
<PAGE>

of Shares),  acceptance for exchange or exchange of any Shares tendered pursuant
to the Offer is delayed,  or Orion is unable to accept for  exchange or exchange
Shares tendered pursuant to the Offer, then, without prejudice to Orion's rights
under  "--  Certain   Conditions   of  the  Offer,"  the  Exchange   Agent  may,
nevertheless,  to the extent  permitted by law, retain tendered Shares on behalf
of Orion and such  Shares may not be  withdrawn  except to the  extent  that the
tendering  shareholders  are entitled to  withdrawal  rights as described  below
under "--  Withdrawal  Rights."  The  ability of Orion to delay the  exchange or
exchange  for the Shares which Orion has accepted for payment is limited by Rule
14e-1 under the Exchange Act referred to above.

         CASH  IN  LIEU  OF  FRACTIONAL   SHARES  OF  ORION  COMMON  STOCK.   No
certificates representing fractional shares of Orion Common Stock will be issued
pursuant to the Offer.  In lieu thereof,  each tendering  shareholder  who would
otherwise be entitled to a  fractional  share of Orion Common Stock will receive
cash in an amount equal to such fraction  (expressed as a decimal and rounded to
the nearest  0.01 of a share) times the average of the high and low sales prices
for shares of Orion  Common  Stock on the NYSE  Composite  Tape on the date such
Guaranty shareholder's Shares are accepted for exchange by Orion.

         PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES.  For Shares to
be validly  tendered  pursuant  to the  Offer,  a  properly  completed  and duly
executed  Letter  of  Transmittal  (or  facsimile  thereof)  with  any  required
signature  guarantees  or  Agent's  Message  (as  defined  below)  and any other
documents required by the Letter of Transmittal must be received by the Exchange
Agent  at any  one  of its  addresses  set  forth  on the  back  cover  of  this
Prospectus, and either (i) the certificates for such Shares must be delivered to
the Exchange  Agent along with the Letter of  Transmittal or such Shares must be
delivered pursuant to the procedure for book-entry  transfer set forth below and
a Book-Entry  Confirmation  must be received by the Exchange Agent, in each case
prior to the Expiration Date, or (ii) the tendering shareholder must comply with
the guaranteed  delivery  procedure set forth below. The term "Agent's  Message"
means a message transmitted by a Book-Entry Transfer Facility to and received by
the Exchange Agent and forming a part of a Book-Entry Confirmation, which states
that such Book-Entry  Transfer  Facility has received an express  acknowledgment
from the participant in such Book-Entry  Transfer Facility  tendering the Shares
which are the subject of such Book-Entry Confirmation, that such participant has
received  and agrees to be bound by the terms of the Letter of  Transmittal  and
that Orion may enforce such agreement against such participant.

         The  Exchange  Agent will make a request to  establish  an account with
respect to the Shares at each of the Book-Entry Transfer Facilities for purposes
of the Offer within two business days after the date of this Prospectus, and any
financial   institution  that  is  a  participant  in  the  Book-Entry  Transfer
Facilities' systems may make book-entry delivery of the Shares by causing DTC or
PDTC,  as the case may be, to transfer  such Shares  into the  Exchange  Agent's
account at such Book-Entry  Transfer Facility in accordance with such Book-Entry
Transfer Facility's procedure for such transfer.  However,  although delivery of
Shares may be effected  through a Book-Entry  Transfer  Facility,  the Letter of
Transmittal (or facsimile thereof) with any required signature guarantees, or an
Agent's Message in connection with a book-entry transfer, and any other required
documents  must, in any case, be transmitted to, and received by, Exchange Agent
at one of its  addresses  set forth on the back cover of this  Prospectus or the


                                       43
<PAGE>

guaranteed  delivery  procedure set forth below must be complied with,  prior to
the Expiration Date.  Delivery of documents to a Book-Entry Transfer Facility in
accordance  with  the  Book-Entry  Transfer   Facility's   procedures  does  not
constitute delivery to the Exchange Agent.

         Except as  otherwise  provided  below,  signatures  on all  Letters  of
Transmittal must be guaranteed by a financial institution (including most banks,
savings and loan  associations  and brokerage  houses) which is a participant in
the Securities  Transfer  Association's  approved medallion program (such as the
Securities  Transfer  Agents  Medallion  Program,  the New York  Stock  Exchange
Medallion  Signature  Program or the Stock Exchange  Medallion Program (each, an
"Eligible  Institution").  Signatures  on  Letters  of  Transmittal  need not be
guaranteed  if the Shares  tendered  thereby are  tendered  (i) by a  registered
holder of Shares who has not completed either the box entitled  "Special Payment
Instructions" or the box entitled "Special Delivery  Instructions" on the Letter
of  Transmittal  or  (ii)  for  the  account  of an  Eligible  Institution.  See
Instructions  1 and 5 of the  Letter of  Transmittal.  If the  certificates  for
Shares are  registered  in the name of a person or persons other than the signer
of the Letter of Transmittal, or if exchange is to be made or unpurchased Shares
are to be issued to a person other than the registered  holder or holders,  then
the certificates must be endorsed or accompanied by appropriate stock powers, in
either  case  signed  exactly as the name or names of the  registered  holder or
holders appear on the  certificates,  with the signatures on the certificates or
stock  powers  guaranteed  as  provided  in the  instructions  to the  Letter of
Transmittal. See Instructions 1 and 5 of the Letter of Transmittal.

         THE METHOD OF DELIVERY  OF SHARES,  THE LETTER OF  TRANSMITTAL  AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING  SHAREHOLDER
AND,  EXCEPT AS OTHERWISE  PROVIDED IN THE LETTER OF  TRANSMITTAL,  THE DELIVERY
WILL BE DEEMED  MADE ONLY WHEN  ACTUALLY  RECEIVED  BY THE  EXCHANGE  AGENT.  IF
DELIVERY IS BY MAIL,  REGISTERED  MAIL WITH RETURN RECEIPT  REQUESTED,  PROPERLY
INSURED,  IS  RECOMMENDED.  IN ALL CASES,  SUFFICIENT  TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.

         If a  shareholder  desires to tender  Shares  pursuant to the Offer and
such   shareholder's   certificates  are  not  immediately   available  or  such
shareholder  is  unable to  deliver  all  documents  required  by the  Letter of
Transmittal  to the  Exchange  Agent  prior  to the  Expiration  Date,  or  such
shareholder  cannot  complete the procedure for book-entry  transfer on a timely
basis,  such  Shares,  nevertheless,  may be  tendered  if all of the  following
conditions are met:

          (i)  such tender is made by or through an Eligible Institution;

          (ii) properly   completed  and  duly  executed  Notice  of  Guaranteed
               Delivery,  substantially  in the form provided by Orion herewith,
               is received by the Exchange  Agent as provided below prior to the
               Expiration Date; and

          (iii)the  certificates  for all  tendered  Shares in  proper  form for
               transfer (or a Book-Entry Confirmation), together with a properly
               completed and duly executed  Letter of Transmittal  (or facsimile
               thereof),  with any required signature guarantees (or in the case
               of a book-entry transfer, an Agent's Message) are received by the


                                       44
<PAGE>

               Exchange  Agent  within three NYSE trading days after the date of
               execution of such Notice of Guaranteed Delivery.

         The  Notice  of  Guaranteed  Delivery  may  be  delivered  by  hand  or
transmitted by telegram,  telex,  facsimile transmission or mail to the Exchange
Agent and must  include a guarantee by an Eligible  Institution  in the form set
forth in such  Notice  of  Guaranteed  Delivery  and a  representation  that the
shareholder on whose behalf the tender is being made is deemed to own the Shares
being tendered within the meaning of Rule 10b-4 under the Exchange Act.

         Notwithstanding  any other provision  hereof,  in all cases payment for
Shares  tendered and accepted for payment (and thus  purchased)  pursuant to the
Offer  will  be  made  only  after  timely  receipt  by the  Exchange  Agent  of
certificates  for  such  Shares  (or  a  Book-Entry  Confirmation),  a  properly
completed and duly executed Letter of Transmittal (or facsimile thereof) and any
other documents required by the Letter of Transmittal.  Accordingly, payment may
be made to  tendering  shareholders  at  different  times if  Shares  and  these
documents are delivered at different times.

         TO PREVENT  BACK-UP  FEDERAL  INCOME TAX  WITHHOLDING  WITH  RESPECT TO
PAYMENT OF THE CASH CONSIDERATION  RECEIVED FOR SHARES PURCHASED PURSUANT TO THE
OFFER, A SHAREHOLDER  MUST PROVIDE THE EXCHANGE AGENT WITH HIS CORRECT  TAXPAYER
IDENTIFICATION  NUMBER AND  CERTIFY  THAT HE IS NOT  SUBJECT TO BACK-UP  FEDERAL
INCOME TAX  WITHHOLDING BY COMPLETING  THE  SUBSTITUTE  FORM W-9 INCLUDED IN THE
LETTER OF  TRANSMITTAL.  CERTAIN  SHAREHOLDERS  (INCLUDING,  AMONG  OTHERS,  ALL
CORPORATION  AND CERTAIN  FOREIGN  INDIVIDUALS)  ARE NOT SUBJECT TO THESE BACKUP
WITHHOLDING  OR REPORTING  REQUIREMENTS.  IN ORDER FOR A FOREIGN  INDIVIDUAL  TO
QUALIFY AS AN EXEMPT  RECIPIENT,  THE SHAREHOLDER MUST SUBMIT A FORM W-8, SIGNED
UNDER PENALTIES OF PERJURY,  ATTESTING TO THAT INDIVIDUAL'S  EXEMPT STATUS.  SEE
INSTRUCTION 8 OF THE LETTER OF TRANSMITTAL.

         By executing a Letter of  Transmittal  as set forth above,  a tendering
shareholder irrevocably appoints designees of Orion as his attorneys-in-fact and
proxies,  each with full power of  substitution,  in the manner set forth in the
Letter of  Transmittal,  to the full  extent of such  shareholder's  rights with
respect to the Shares  tendered by such  shareholder and accepted for payment by
Orion  (and any  associated  Rights and all other  Shares  and other  securities
issued or issuable in respect thereof on or after the date of this  Prospectus).
All such proxies  shall be  considered  coupled with an interest in the tendered
Shares.  Such  appointment  will be effective when, and only to the extent that,
Orion  accepts  such Shares for  payment,  which will be no earlier than       ,
1997. Upon such acceptance for payment,  all prior proxies given with respect to
such Shares and other securities will, without further action, be revoked and no
subsequent proxies may be given (and if given will not be deemed effective). The
designees of Orion will be empowered, among other things, to exercise all voting
and other rights of such shareholder with respect to Shares and other securities
accepted for payment as they, in their sole  discretion,  may deem proper at any
annual,  special or adjourned  meeting of  Guaranty's  shareholders,  by written
consent or  otherwise.  Orion  reserves the right to require  that, in order for
Shares to be deemed validly  tendered,  immediately upon Orion's  acceptance for


                                       45
<PAGE>

payment of such  Shares,  Orion must be able to  exercise  full voting and other
rights  with  respect  to such  Shares  and other  securities  issued in respect
thereof.

         All questions as to the validity,  form, eligibility (including time of
receipt) and acceptance  for payment of any tender of Shares  pursuant to any of
the  procedures  described  above  will be  determined  by  Orion,  in its  sole
discretion,  which determination shall be final and binding.  Orion reserves the
absolute  right to reject any or all tenders of any Shares  determined by it not
to be in proper  form or if the  acceptance  for  payment of or payment for such
Shares may, in the opinion of Orion's counsel, be unlawful.  Orion also reserves
the right to waive any defect or  irregularity in any tender with respect to any
particular Shares of any particular  shareholder,  and Orion's interpretation of
the terms and conditions of the Offer  (including the Letter of Transmittal  and
the Instructions  thereto) will be final and binding.  None of Orion, the Dealer
Manager,  the Exchange Agent, the Information Agent, or any other person will be
under any duty to give  notification  of any  defects or  irregularities  in the
tender of any Shares or will incur any  liability  for  failure to give any such
notification.

         It is a violation of Rule 14e-4 promulgated under the Exchange Act, for
a person,  directly or  indirectly,  to tender Shares for his or her own account
unless the person so tendering (i) has a net long  position  equal to or greater
than the number of Shares tendered or other securities  immediately  convertible
into, or  exercisable  or  exchangeable  for such number of Shares and (ii) will
cause such Shares to be  delivered  in  accordance  with the terms of the Offer.
Rule 14e-4 provides a similar restriction  applicable to the tender or guarantee
of a tender on behalf of another person.

         A tender of Shares  pursuant to any of the procedures  described  above
will constitute a binding agreement between the tendering  shareholder and Orion
upon the terms  and  subject  to the  conditions  of the  Offer,  including  the
tendering shareholder's  acceptance of the terms and conditions of the Offer, as
well as the tendering  shareholder's  representation  and warranty that (i) such
shareholder  has a net long  position in the Shares  being  tendered  within the
meaning of Rule 14e-4 under the  Exchange Act and (ii) the tender of such Shares
complies with Rule 14e-4.

         WITHDRAWAL  RIGHTS.  Except as  otherwise  provided  below,  tenders of
Shares (and if applicable,  Rights) made pursuant to the Offer are  irrevocable.
Upon the terms and  subject  to the  conditions  of the Offer,  Shares  tendered
pursuant to the Offer may be withdrawn at any time prior to the Expiration  Date
and,  unless  theretofore  accepted for exchange and  exchanged by Orion for the
Offer  Consideration  pursuant to the Offer,  may also be  withdrawn at any time
after               , 1997.

         For  withdrawal to be effective,  a written,  telegraphic  or facsimile
transmission  notice of withdrawal must be timely received by the Exchange Agent
at one of its addresses set forth on the back cover of this Prospectus. Any such
notice of withdrawal must specify the name of the person who tendered the Shares
to be  withdrawn,  the  number  of Shares  to be  withdrawn  and the name of the
registered  holder,  if different  from that of the person having  tendered such
Shares.  If certificates for Shares have been delivered or otherwise  identified
to the Exchange Agent, then, prior to the physical release of such certificates,
the  withdrawing  shareholder  also must submit to the Exchange Agent the serial


                                       46
<PAGE>

numbers  shown  on the  particular  certificates  evidencing  the  Shares  to be
withdrawn,  and the signature on the notice of withdrawal  must be guaranteed by
an Eligible  Institution,  except in the case of Shares tendered for the account
of an  Eligible  Institution.  If Shares  have been  delivered  pursuant  to the
procedure for book-entry  transfer set forth under "Procedures for Accepting the
Offer and Tendering  Shares," any notice of withdrawal must specify the name and
account  number of the account at a Book Entry  Facility to be credited with the
withdrawn Shares.

         Any Shares (or Rights, if applicable) properly withdrawn will be deemed
not to be validly tendered for purposes of the Offer. However,  withdrawn Shares
(or  Rights,  if  applicable)  may  be  re-tendered,  by  following  any  of the
procedures  described under "-- Procedures for Accepting the Offer and Tendering
Shares" at any subsequent time prior to the Expiration Date.

         A  withdrawal  of Shares  shall also  constitute  a  withdrawal  of the
associated Rights.  Rights may not be withdrawn unless the associated Shares are
also withdrawn.

On          ,  1997, the last full trading day prior to the  commencement of the
Offer,  the closing  sales price  reported by the NYSE was  $         per Share.
GUARANTY  SHAREHOLDERS  ARE URGED TO OBTAIN  CURRENT  MARKET  QUOTATIONS FOR THE
SHARES.

         During 1994  Guaranty  repurchased  459,200  Shares,  of which  139,600
Shares were purchased from  subsidiaries of Orion. The average  repurchase price
of  Shares  repurchased  was  $14.45.  To  Orion's   knowledge,   no  additional
repurchases  of Shares have been made by Guaranty  since  December 31, 1994.  In
view of applicable  regulations  under the Exchange Act,  Orion expects that any
repurchase program would be suspended during the Offer.

EFFECT  OF THE  OFFER ON THE  MARKET  FOR THE  SHARES;  QUOTATION  ON THE  NYSE;
REGISTRATION UNDER THE EXCHANGE ACT.

         The  purchase of Shares by Orion  pursuant to the Offer will reduce the
number of Shares that might  otherwise  trade publicly and, if the Minimum Share
Condition  is  satisfied,  would  substantially  reduce the number of holders of
Shares and will adversely affect the liquidity,  and possibly,  the market value
of the remaining Shares held by the public.

         The  Shares  are  listed  and  principally  traded on the NYSE.  If the
Minimum Share Condition is satisfied,  following  consummation of the Offer, the
Shares would likely no longer meet the  requirements  of the NYSE for  continued
listing.  For example,  according to the NYSE's published  guidelines,  the NYSE
would consider delisting the Shares if, among other things, the number of record
holders of at least 100 or more Shares  should fall below  1,200,  the number of
publicly  held  Shares  (exclusive  of holdings of  officers,  directors,  their
immediate  families  and  other  concentrated  holdings  of 10% or  more  ("NYSE
Excluded  Holdings")) should fall below 600,000 or the aggregate market value of
publicly held Shares  (exclusive of NYSE  Excluded  Holdings)  should fall below
$5,000,000.

         According  to the 1996 Annual  Report on Form 10-K of  Guaranty,  there
were  approximately  2,400  holders of Shares as of February 28,  1997.  If as a
result of the purchase of Shares pursuant to the Offer or otherwise,  the Shares
no longer meet the requirements of the NYSE for continued listing and/or trading
and such  trading of the  Shares  were  discontinued,  the market for the Shares
could be adversely affected.

         In the  event all  outstanding  Tender  Shares  are  exchanged  or upon
consummation  of any subsequent  merger,  Orion intends to seek delisting of the
shares for trading on the NYSE. In the event that the Shares should no longer be
listed or  traded  on the NYSE,  it is  possible  that the  Shares  may trade on
another national securities exchange or in the over-the-counter  market and that
price quotations would be reported by such exchange, through the NASDAQ or other
sources.  Orion does not presently intend to request or support such initiatives
if delisting occurs.

         In  the  event  that  a  merger  is  effected  between  Guaranty  and a
wholly-owned  subsidiary of Orion following the  consummation of the Offer,  the
Shares would be delisted by the NYSE and deregistered under the Exchange Act.



                                       48
<PAGE>

         The  Shares are  currently  registered  under the  Exchange  Act.  Such
registration  may be  terminated  if the Shares  are not  listed on a  "national
securities  exchange"  and there are fewer  than 300  record  holders of Shares.
Termination  of  registration  of  the  Shares  under  the  Exchange  Act  would
substantially reduce the information required to be furnished by Guaranty to its
shareholders and the SEC and would make certain  provisions of the Exchange Act,
such as the  short-swing  profit  recovery  provisions  of Section 16(b) and the
requirements of furnishing a proxy  statement in connection  with  shareholders'
meetings  pursuant to Section 14(a),  no longer  applicable to Guaranty.  If the
Shares should no longer be registered  under the Exchange Act, the  requirements
of  Rule  13e-3  under  the  Exchange  Act  with  respect  to  "going   private"
transactions would no longer be applicable to Guaranty. Furthermore, the ability
of  "affiliates"  of Guaranty and persons  holding  "restricted  securities"  of
Guaranty to dispose of such securities  pursuant to Rule 144  promulgated  under
the Securities Act may be impaired or eliminated.

         In the event that all of the Tender  Shares are  exchanged  pursuant to
the Offer, or upon consummation of any subsequent merger,  Orion intends to seek
to have Guaranty's shares deregistered under the Exchange Act.

MARGIN REGULATIONS

         The Shares are currently  "margin  securities" under the regulations of
the Board of  Governors  of the Federal  Reserve  System (the  "Federal  Reserve
Board"),  which have the effect,  among  other  things,  of allowing  brokers to
extend  credit on the  collateral  of such  Shares  for the  purpose  of buying,
carrying or trading in securities ("Purpose Loans").  Following  consummation of
the  Offer,  the  Shares  might no longer  constitute  "margin  securities"  for
purposes of the Federal Reserve Board's margin  regulations and,  therefore,  no
longer be able to be used as collateral  for Purpose  Loans made by brokers.  In
addition,  if  registration  of the  Shares  under the  Exchange  Act  should be
terminated, the Shares would no longer constitute "margin securities."

DIVIDENDS AND OTHER DISTRIBUTIONS

         Except for any action taken by Guaranty which shall have been expressly
approved in writing by Orion:

         If, on or after September 18, 1997,  Guaranty should declare or pay any
dividend on the Shares or other distribution except for the Regular Dividend (as
defined below) (including, without limitation, the issuance of additional Shares
pursuant to the Rights,  a stock dividend or stock split,  the issuance of other
securities,  or the issuance of rights for the purchase of any securities)  with
respect to the Shares that is payable or distributable to shareholders of record
on a date  prior  to the  transfer  to the  name  of  Orion  or its  nominee  or
transferee on Guaranty's stock transfer records of the Shares purchased pursuant
to the Offer,  then,  without prejudice to Orion's rights as set forth under "--
Certain Conditions of the Offer," (i) the Offer  Consideration per Share payable
by Orion, pursuant to the Offer shall be reduced to the extent any such dividend
or distribution is payable in cash and (ii) any non-cash dividend,  distribution
or right including the Rights shall be remitted by the tendering  shareholder to
the  Exchange  Agent  for the  account  of  Orion,  accompanied  by  appropriate
documentation of transfer.  Pending such  remittance,  and subject to applicable


                                       49
<PAGE>

law,  Orion shall be entitled to all rights and  privileges as owner of any such
non-cash  dividend,  distribution  or right and may withhold the entire purchase
price or  deduct  from the  purchase  price  the  amount  or value  thereof,  as
determined by Orion in its sole discretion. Guaranty has, since January 1, 1995,
declared regular quarterly dividends at the rate of $0.125 per share. If, during
the third quarter or fourth quarter of 1997 Guaranty  declares a dividend of not
more than $0.125 per share (the  "Regular  Dividend"),  Orion does not intend to
adjust  the Offer  Consideration  should  the  record  date for  payment of such
Regular  Dividend be a date prior to Orion's  acceptance for payment and payment
for Shares tendered pursuant to the Offer.

         If, on or after September 18, 1997, Guaranty should (i) split,  combine
or  otherwise  change the Shares or its  capitalization,  (ii) issue or sell any
additional  securities of Guaranty or cause  pursuant to the Rights or otherwise
an increase in the number of outstanding securities of Guaranty or (iii) acquire
currently  outstanding  Shares or  otherwise  cause a reduction in the number of
outstanding  Shares,  or shall  disclose  that it has taken such  action,  then,
without prejudice to Orion's rights under "-- Certain  Conditions of the Offer,"
Orion,  in  its  sole  discretion,  may  make  such  adjustments  in  the  Offer
Consideration and other terms of the Offer (including,  without limitation,  the
number and type of securities to be purchased) as it deems appropriate.

CERTAIN CONDITIONS OF THE OFFER

         Notwithstanding  any other  provision of the Offer,  and in addition to
(and not in limitation  of) Orion's rights to amend the Offer at any time in its
sole discretion, Orion will not be required to accept for exchange, or exchange,
any Shares tendered,  and may terminate,  extend or amend the Offer, or, subject
to  the   provisions  of  applicable  law  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,  may delay
the acceptance for exchange or the exchange of Shares tendered,  if, at any time
on or after  September 18, 1997,  and at or prior to the time of payment for any
such Shares  (whether  or not any Shares  have  theretofore  been  accepted  for
exchange or exchanged for pursuant to the Offer),  any of the  following  events
shall occur,  which in the sole judgment of Orion, in any case and regardless of
the  circumstances  giving rise to any such  condition  (including any action or
inaction by Orion or any of its subsidiaries or affiliates) makes it inadvisable
to proceed with the Offer or with acceptance for exchange or exchange of Shares.

         THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS,  THERE BEING VALIDLY
TENDERED  AND NOT  WITHDRAWN  PRIOR TO THE  EXPIRATION  DATE A NUMBER  OF SHARES
WHICH, EXCLUDING SHARES OWNED BY ORION AND ITS WHOLLY-OWNED  SUBSIDIARIES,  WILL
CONSTITUTE AT LEAST 50.01% OF THE TOTAL NUMBER OF  OUTSTANDING  SHARES AS OF THE
DATE THE SHARES ARE ACCEPTED FOR EXCHANGE BY ORION PURSUANT TO THE OFFER.  Based
on the  foregoing,  Orion  expects that this Minimum  Share  Condition  would be
satisfied  if at least an aggregate  of      Shares  expected to be  outstanding
immediately prior to the consummation of the Offer are validly tendered pursuant
to the Offer and not withdrawn. Orion does not intend, without the approval of a
majority of the  independent  directors of Guaranty,  to waive the Minimum Share
Condition.



                                       50
<PAGE>

         If the Rights shall have become exercisable or for any reason Orion and
its  subsidiaries  shall not be deemed to be "Exempt  Persons" (the "Rights Plan
Condition") (see "-- Certain Legal Matters -- (e) Guaranty's  Charter Documents;
The Shareholder Agreement;  The Rights Plan and Other Matters"),  then Orion may
in its sole discretion refuse to accept Shares tendered for exchange.

         If the Orion  Average  Price shall be greater  than $51.25 or less than
$37.88  (the  "Orion  Average  Price  Condition"),  then  Orion  may in its sole
discretion refuse to accept Shares tendered for exchange.

         The  Offer is  conditioned  on the  requirement  that the  Registration
Statement shall have become effective under the Securities Act and no stop order
suspending  the  effectiveness  of the  Registration  Statement  shall have been
issued  and no  proceedings  for that  purpose  shall  have  been  initiated  or
threatened  by the SEC,  and that the Shares  which  shall be issued to Guaranty
shareholders  in the Offer shall have been  authorized  for listing on the NYSE,
subject only to official notice of issuance.  In addition,  as described  below,
the Offer is conditioned on all regulatory  approvals required to consummate the
Offer having been obtained and remaining in full force and effect, all statutory
waiting  periods  in  respect  thereof  having  expired  and  no  such  approval
containing  any  conditions or  restrictions  which the Orion Board of Directors
determines  will or could be expected  materially  to impair the  strategic  and
financial  benefits expected to result from the offer (the "Regulatory  Approval
Condition").

         In addition, the Offer is conditioned upon none of the following events
having occurred.

         (a) any change shall have  occurred or be  threatened  in the business,
operations  or  financial  condition of Guaranty or any of its  subsidiaries  or
affiliates  which  is or  which  Orion in its  sole  discretion  believes  to be
materially adverse to Guaranty and its subsidiaries taken as a whole;

         (b) there shall have been threatened,  instituted or pending any action
or   proceeding   by  or  before  any  court  or   governmental   regulatory  or
administrative  agency,  authority or tribunal,  domestic or foreign,  which (i)
seeks to  challenge  the  acquisition  by Orion of the Shares,  or to  restrain,
prohibit or delay the making or  consummation  of the Offer,  (ii) seeks to make
the purchase of, or payment for, some or all of the Shares pursuant to the Offer
illegal,  (iii) seeks to impose material limitations on the ability of Orion (or
any of its affiliates) effectively to acquire or hold, or requires any of Orion,
or Guaranty, or any of their respective affiliates or subsidiaries to dispose of
or hold  separate,  any material  portion of the assets or the business of Orion
and its affiliates taken as a whole or Guaranty and its subsidiaries  taken as a
whole, (iv) seeks to impose material limitations on the ability of Orion (or its
affiliates)  to  exercise  full  rights of  ownership  of the Shares  purchased,
including,  but not  limited to, the right to vote the Shares  purchased  on all
matters properly  presented to the shareholders of Guaranty or (v) may result in
a  material  diminution  in the  benefits  expected  to be derived by Orion as a
result of the  transactions  contemplated  by the Offer (see "--  Certain  Legal
Matters");

         (c) there  shall  have been  proposed,  sought,  promulgated,  enacted,
entered,  enforced or deemed  applicable to the Offer, by any state,  federal or


                                       51
<PAGE>

foreign  government  or  governmental  authority  or by any  domestic or foreign
court, any statute, rule, regulation,  judgment,  order or injunction,  that, in
the sole judgment of Orion, might, directly or indirectly,  result in any of the
consequences referred to in clauses (i) through (v) of (b) above;

         (d) Orion or  Guaranty  shall  otherwise  have  failed to  receive  any
governmental  or third party  consents and  approvals,  which,  if not received,
would in the aggregate  have or be reasonably  anticipated  to have a materially
adverse effect on Orion or Guaranty or any of their respective subsidiaries,  or
Orion shall have  determined in good faith that  consummation of the Offer would
cause a breach of or constitute  (with or without due notice or lapse of time or
both) a  default  (or give  rise to any right of  termination,  cancellation  or
acceleration)  under agreements or other  obligations of Orion or Guaranty which
would individually or in the aggregate have or be reasonably anticipated to have
a  materially  adverse  effect on Orion or Guaranty  or any of their  respective
subsidiaries;

         (e) there shall have occurred (i) any general suspension of trading in,
or limitation on prices for,  securities on any national  securities exchange or
in the  over-the-counter  market in the United States, (ii) the declaration of a
banking  moratorium  or any  suspension  of  payments in respect of banks in the
United  States,  (iii) a material  adverse  change in United States or any other
currency  exchange  rates or a suspension  of, or a  limitation  on, the markets
therefor,   (iv)  the  commencement  of  a  war,  armed   hostilities  or  other
international or national calamity  directly or indirectly  involving the United
States,  (v) any  limitation  (whether  or not  mandatory)  by any  governmental
authority  on, or any other event which,  in the sole  judgment of Orion,  might
affect the extension of credit by banks or other lending  institutions,  or (vi)
in the case of any of the foregoing  existing at the time of the commencement of
the Offer,  in the sole judgment of Orion, a material  acceleration or worsening
thereof;

         (f) unless Orion shall have  consented  in writing,  Guaranty or any of
its  subsidiaries  shall  have,  on or after  September  18,  1997,  (i) issued,
distributed, pledged or sold, or authorized, proposed or announced the issuance,
distribution,  pledge or sale of (A) any  shares of  capital  stock  (including,
without limitation, the Shares), or securities convertible into any such shares,
or any rights,  warrants,  or options to acquire any such shares or  convertible
securities,  other than Shares  issued or sold upon the exercise (in  accordance
with, and without amendment or waiver of, the present terms thereof) of employee
stock options  outstanding on September 18, 1997 or (B) any other  securities in
respect  of,  in lieu of,  or in  substitution  for  Shares  (ii)  purchased  or
otherwise acquired, or proposed or offered to purchase or otherwise acquire, any

proposed or  announced  its  intention  to  authorize,  recommend or propose any
transaction  which  could  adversely  affect  the  value  of the  Shares,  (vii)
proposed,  adopted or authorized any amendment to its articles of  incorporation
or by-laws or similar organizational documents or Orion shall have learned about
any such proposal or amendment which shall not have been previously disclosed or

         (g)  Guaranty or any of its  subsidiaries  shall have  entered into any
employment,  severance or similar agreement, arrangement or plan with any of its
employees  other than in the  ordinary  course of  business  or entered  into or
amended any  agreements,  arrangements  or plans so as to provide for  increased
benefits to the employee as a result of or in connection  with the  transactions

         (h) a tender or  exchange  offer for some  portion or all of the Shares
shall have been publicly  proposed to be made or shall have been made by another
person  (including  Guaranty or any of its  subsidiaries or  affiliates),  or it
shall have been  publicly  disclosed  or Orion shall have  learned  that (i) any
person or "group" (as defined in Section  13(d) (3) of the  Exchange  Act) shall
have  acquired  or  proposed  to acquire  more than 5% of any class or series of
capital stock of Guaranty  (including the Shares) or shall have been granted any
option or right to acquire more than 5% of any class or series of capital  stock
of  Guaranty  (including  the  Shares),  other than  acquisitions  for bona fide
arbitrage  positions and other than  acquisitions  by persons or groups who have
publicly disclosed such ownership on or prior to September 18, 1997, or (ii) any
such person or group who has publicly  disclosed any such ownership of more than
5% of any class or series of capital  stock of Guaranty  (including  the Shares)

(including the Shares) or shall have been granted any option or right to acquire
more than 2% of any class or series of capital stock of Guaranty  (including the
Shares); or

         The foregoing  conditions  are for the sole benefit of Orion and may be
asserted  by  Orion  regardless  of the  circumstances  giving  rise to any such
condition and may (with the exception of the Minimum Share  Condition) be waived
by  Orion,  in whole or in part,  at any time and from  time to time in its sole
discretion.  The failure by Orion at any time to exercise their rights under any
of the foregoing  conditions shall not be deemed a waiver of any such rights and
each such right  shall be deemed an ongoing  right  which may be asserted at any
time or from time to time.  Any  determination  by Orion  concerning  the events
described in the foregoing  conditions will be final and binding on all parties,
including tendering shareholders.

CERTAIN LEGAL MATTERS

         Based upon Orion's examination of publicly available  information filed
by Guaranty with the SEC and other publicly  available  information with respect
to Guaranty , except as  otherwise  set forth in this  Prospectus,  Orion is not
aware of any license or  regulatory  permit which  appears to be material to the


                                       53
<PAGE>

business of Guaranty and its  subsidiaries  that might be adversely  affected by
the acquisition of Shares pursuant to the Offer, or, except as disclosed herein,
of any  approval or other  action  (other than an  informational  filing) by any
state,  federal or foreign  governmental or  administrative or regulatory agency
that would be required for the acquisition of the Shares as contemplated herein.
Should any such  license,  permit,  approval or other action be required,  it is
presently  contemplated that the same would be sought, except as described below
under "State Takeover  Statutes." While Orion does not currently intend to delay
the acceptance for payment of, or payment for, Shares pending the outcome of any
such  matters,  there can be no  assurance  that any license,  permit,  consent,
approval  or other  action,  if needed,  would be obtained  without  substantial
conditions or that adverse  consequences might not result to Guaranty's business
or that certain parts of Guaranty's business might not have to be disposed of or
held separate or other  substantial  conditions  complied with in the event that
such license, permit or approval is not obtained or any such other action is not
taken.  Orion's  obligation  under the Offer to accept for exchange and exchange
Shares is subject to certain  conditions,  including  conditions relating to the
legal matters discussed herein and, if certain types of adverse action are taken
with respect to the matters  discussed below,  Orion could decline to accept for
exchange any Shares tendered. See "-- Certain Conditions of the Offer."

          Orion  understands  that on September  18, 1997, an  action  was filed
in the Denver  District  Court,  City and County of Denver,  Colorado,  entitled
EUGENIA  GLADSTONE  VOGEL  V.  GUARANTY  NATIONAL  CORPORATION;   ORION  CAPITAL
CORPORATION;  TUCKER HART ADAMS; W. MARSTON BECKER;  VINCENT T. PAPA;  DENNIS J.
LACEY; M. ANN PADILLA; JAMES R. POULIOT; ROBERT B. SANBORN;  WILLIAM J. SHEPERD;
RICHARD R. THOMAS;  AND ROGER B. WARE. The action challenges the fairness of the
Offer and seeks an unspecified amount of damages,  attorneys fees and injunctive
relief.  Orion believes the complaint to be without merit and intends to contest
it.

         (a) STATE INSURANCE APPROVALS. Guaranty is an insurance holding company
whose insurance  company  subsidiaries and affiliates are domiciled in Colorado,
Wisconsin,  California,  Oklahoma and Texas.  Orion is deemed to be the ultimate
parent of those insurance  company  subsidiaries  and affiliates.  The Insurance
Holding  Company  System  Act of some of those  states  requires  the  filing of
information  with the insurance  commissioner in order to obtain approval of the
acquisition of additional voting securities of a domestic insurer  (including an
insurance  holding  company).  In connection  with the 1996 Tender Offer,  Orion
obtained  all  approvals  necessary  to  consummate  the Offer and to accept any
Shares properly tendered for exchange.

         (b) STATE TAKEOVER  STATUTES.  A number of states have adopted laws and
regulations  that  purport  to be  applicable  to  offers to  acquire  shares of
corporations  that are  incorporated or have  substantial  assets,  shareholders
and/or a principal place of business in such states. In Edgar v. MITE Corp., the
U.S.  Supreme  Court held that the Illinois  Business  Takeover  Statute,  which
involved state  securities laws which made the takeover of certain  corporations
more  difficult,  imposed a substantial  burden on  interstate  commerce and was
therefore unconstitutional.  However, in 1987 the U.S. Supreme Court held in CTS
Corp. v. Dynamics Corp. of America,  that, at least under certain circumstances,
the U.S.  Constitution  permits a state,  as a matter of  corporate  law and, in
particular,   those  laws  concerning  corporate  governance,  to  disqualify  a
potential  acquiror from voting on the affairs of a target  corporation  without


                                       54
<PAGE>

prior approval of the remaining shareholders.  Subsequently, a number of Federal
courts ruled that various state takeover statutes were unconstitutional  insofar
as they apply to corporations incorporated outside the state of enactment. Orion
believes  that no such statute  purporting to be applicable to offers to acquire
shares of a corporation has been enacted or is in effect in Colorado,  the state
of incorporation of Guaranty.

         Guaranty and certain of its subsidiaries directly or indirectly conduct
business in a number of other states throughout the United States, some of which
have enacted takeover laws and  regulations.  Orion does not know whether any of
these laws  will,  by its  terms,  apply to the  Offer.  The Offer is being made
without  compliance  by Orion with any such  state  takeover  statutes  that may
purport to apply to the Offer. Should any governmental  official or other person
seek to apply any such statute or regulation to the Offer,  Orion will take such
action as then appears desirable, and presently anticipate, that it will contest
the  applicability  or validity of any such statute or regulation in appropriate
court  proceedings.  If it is asserted that one or more state takeover  statutes
are applicable to the Offer,  and an  appropriate  court does not determine that
such statutes are  inapplicable or invalid as applied to the Offer,  Orion might
be unable to accept for  exchange or exchange  shares of Orion  Common Stock for
Shares tendered  pursuant to the Offer, or be delayed in accepting or exchanging
Shares  pursuant  to the Offer.  In such case,  Orion will not be  obligated  to
accept for  exchange or exchange  shares of Orion  Common  Stock for Shares.  In
addition,  Orion may  terminate  the  Offer if it  becomes  subject  to an order
preventing it from purchasing Shares or limiting its ability to exercise control
of Guaranty. See "-- Conditions to the Offer."

         (c) ANTITRUST.  Under the Hart-Scott-Rodino  Antitrust Improvements Act
of 1976,  as amended  (the "HSR  Act"),  and the rules  promulgated  thereunder,
certain  acquisition  transactions may not be consummated unless information has
been  furnished to the Federal  Trade  Commission  (the "FTC") and the Antitrust
Division of the Department of Justice (the "Antitrust  Division") and applicable
waiting period requirements have been satisfied. Pursuant to the requirements of
the HSR Act in  connection  with the 1996 Tender  Offer,  on May 8, 1996,  Orion
filed a  Notification  and Report Form with respect to the  acquisition  of more
than 50% of the equity of the Company with the FTC and the  Antitrust  Division.
All waiting  periods under the HSR Act were  satisfied and no further  action is
required  by  Orion  with  respect  to the  Offer.  See,  however,  "--  Certain
Conditions of the Offer."

         (d) MERGERS AND BUSINESS COMBINATIONS. As described under "The Offer --
Reasons for the Offer,"  Orion  reserves the right,  to the extent  permitted by
applicable  law,  to acquire  additional  Shares  following  the  expiration  or
termination of the Offer.  Such  acquisitions may be made through a tender offer
or exchange offer, or otherwise, on such terms and at such prices as Orion shall
determine.  Orion also  reserves the right to dispose of any or all Shares which
it owns. The  acquisition  of Shares by Orion may be subject to compliance  with
the requirements of Rule 13e-3 promulgated under the Exchange Act, which applies
to certain "going-private" transactions. If Orion were to consummate a merger or
similar business  combination,  or seek to undertake certain other actions,  the
shareholders of Guaranty might have the right to dissent therefrom and to obtain
payment for the fair value of their  Shares in  accordance  with  Colorado  law.
Statutory  appraisal rights are not available under Colorado law with respect to
the Offer.



                                       55
<PAGE>

         Guaranty  is a  Colorado  corporation  and is  governed  by the laws of
Colorado.  Several  decisions by courts of states other than  Colorado have held
that, in certain instances, a controlling  shareholder of a corporation involved
in a merger has a fiduciary  duty to the other  shareholders  that requires that
the merger be fair to such other  shareholders.  In determining whether a merger
is fair to  minority  shareholders,  such courts  have  considered,  among other
things,  the type and amount of consideration to be received by the shareholders
and whether there were fair dealings  among the parties.  In the leading case in
this area, the Delaware Supreme Court indicated in Weinberger v. UOP, Inc. that,
in most cases,  the remedy  available in a merger that is found not to be "fair"
to minority shareholders is the right to appraisal or a damages remedy.

         Pursuant to Section 7-111-104 of the Colorado Business Corporation Act,
after Orion has obtained 90% ownership of Guaranty,  if Orion were to consummate
a merger  with  Guaranty,  Orion  would be able to  effect a  short-form  merger
without  the vote of the board of  directors  or  minority  shareholders  of the
Guaranty voting on the transaction.

         (e) GUARANTY'S CHARTER DOCUMENTS; THE SHAREHOLDER AGREEMENT; THE RIGHTS
PLAN AND OTHER MATTERS.  Guaranty's  Articles of  Incorporation,  as amended and
restated,  authorize  Guaranty's  Board of  Directors  to set the terms of,  and
provide for the issuance of, one or more series of preferred  stock  without the
vote of  Guaranty's  existing  shareholders.  In the  event  that  the  Board of
Directors of Guaranty  authorizes  the  issuance by Guaranty of preferred  stock
upon  terms  that  would  render  consummation  of the  Offer  impracticable  or
undesirable  to Orion,  Orion will have no  obligation to accept for exchange or
exchange  any  Shares  pursuant  to  the  Offer.  Pursuant  to  the  Shareholder
Agreement, three members of the present Board of Directors of Guaranty have been
nominated by Orion.  Guaranty's Board of Directors  consists of ten members.  As
indicated  under "Special  Factors -- Background of the Offer," Orion  undertook
during the 1996 Tender Offer that no  repurchase of its own shares would be made
by Guaranty  without the approval of a majority of directors of Guaranty who are
not employees or directors of Orion.

         In November  1991,  the Board of  Directors  of Guaranty  approved  the
adoption of a Shareholder Rights Agreement and in connection  therewith declared
a dividend  distribution of one Right for each outstanding Share until such time
as separate Right certificates are distributed (the "Distribution  Date") or the
Rights are  redeemed  or expire.  When  exercisable,  each Right will  entitle a
holder to purchase from Guaranty a unit  consisting  of one  one-hundredth  of a
share of a new series of Guaranty's  preferred  stock at a purchase price of $60
per  share.   The  Rights  become   exercisable  ten  days  following  a  public
announcement  that a person or group of acquirers (other than "Exempt  Persons")
has  acquired or obtained the rights to acquire  beneficial  ownership of 20% or
more of Guaranty's common stock or ten business days following announcement of a
tender offer or exchange offer that could result in beneficial  ownership of 20%
or more of Guaranty's common stock. Prior to consummation of such a transaction,
each holder of a Right is entitled to purchase shares of Guaranty's common stock
having a value equal to two times the exercise price of the Right.  Guaranty has
the right to redeem the Rights at $.01 per Right  prior to the time they  become
exercisable. The Rights will expire on December 30, 2001. In accordance with the


                                       56
<PAGE>

form of Rights Agreement included in Guaranty's Current Report on Form 8-K filed
with the SEC on December 19, 1991,  Orion believes that it and its  subsidiaries
are  "Exempt  Persons" as defined in the Rights  Agreement,  that at the present
time the Rights are not  exercisable,  that the Rights Plan is applicable to the
Offer and that the Offer should not result in the Rights becoming exercisable.

FEES AND EXPENSES

         Orion  has  retained  State  Street  Bank and Trust  Company  to act as
Exchange  Agent in connection  with the Offer.  The Exchange  Agent will receive
reasonable  and  customary  compensation  for its  services.  D.F. King has been
retained  by Orion  as  Information  Agent in  connection  with the  Offer.  The
Information  Agent may  contact  holders  of Shares by mail,  telephone,  telex,
telegraph  and personal  interview  and may request  brokers,  dealers and other
nominee  shareholders  to forward  material  relating to the Offer to beneficial
owners.  Reasonable and customary  compensation  will be paid for such services.
DLJ is acting as Dealer  Manager and financial  adviser in  connection  with the
Offer.  Orion has agreed to pay DLJ a fee of $            for such services.  In
1996 DLJ acted in a similar  capacity in  connection  with the 1996 Tender Offer
and in July 1995, DLJ acted as co-manager for Orion's  $100,000,000  Senior Note
offering. In 1996-1997, DLJ has advised Orion in various transactions, including
acting as lead manager in  connection  with issuance by Orion of $125 million of
trust  preferred  securities.  Orion has agreed to reimburse the Exchange Agent,
the  Dealer  Manager  and the  Information  Agent for  reasonable  out-of-pocket
expenses and to indemnify each of them against certain liabilities and expenses,
including,  in the case of the Dealer  Manager and  Information  Agent,  certain
liabilities under the federal securities laws.

         It is estimated that the expenses  incurred by Orion in connection with
the Offer will be  approximately  as set forth below (if all of the Shares other
than those held by Orion's wholly-owned subsidiaries are purchased):

        Filing Fees................................................    $
        Printing and mailing fees..................................    $
        Accounting and legal fees..................................    $
        Dealer Manager fee.........................................    $
        Exchange Agent fees........................................    $
        Miscellaneous..............................................    $_____
                                                                       $

         Except as set forth herein,  Orion will not pay any fees or commissions
to  any  broker  or  dealer  or to any  other  person  in  connection  with  the
solicitation  of tenders of Shares  pursuant  to the  Offer.  Brokers,  dealers,
commercial  banks and trust  companies will be reimbursed for customary  mailing
and  handling  expenses  incurred  by  them  in  forwarding  material  to  their
customers.  Except as set forth in this  Prospectus,  no  persons  or classes of
persons have been employed or retained or are to be  compensated  by Orion or by
any person,  to make  solicitations  or  recommendations  in connection with the
Offer,  and no officer,  employee or class of employees  or  corporate  asset of
Guaranty has been or is proposed to be employed, availed or utilized by Orion in
connection with the Offer.



                                       57

SOURCE AND AMOUNT OF FUNDS -- FINANCING OF THE OFFER

         The Offer  Consideration  consists  in part of Orion  Common  Stock and
$27.20 net in cash per Share and an immaterial amount of cash to be paid in lieu
of fractional  shares of Orion Common Stock.  Such aggregate amount in cash will
be paid from Orion's available cash and short-term investments.

MISCELLANEOUS

         The Offer is not being made to, nor will tenders be accepted  from,  or
on behalf of, holders of Shares in any  jurisdiction  in which the making of the
Offer or the acceptance  thereof would not be in compliance with the securities,
blue  sky or  other  laws of  such  jurisdiction.  However,  Orion  may,  at its
discretion, take such action as they may deem necessary to make the Offer in any
such   jurisdiction   and  extend  the  Offer  to  holders  of  Shares  in  such
jurisdiction.  In those jurisdictions whose securities laws require the Offer to
be made by a licensed broker or dealer,  the Offer shall be deemed to be made on
behalf  of  Orion,  if at all,  only  by the  Dealer  Manager  or by one or more
registered brokers or dealers licensed under the laws of such jurisdictions.

         As indicated under  "Available  Information,"  Orion will file with the
SEC a transaction  statement on Schedule  13E-3 and a tender offer  statement on
Schedule  14D-1,  together with exhibits,  pursuant to Rule 13e-3 and Rule 14d-3
respectively  of the  General  Rules and  Regulations  under the  Exchange  Act,
furnishing  certain  additional  information  with respect to the Offer, and may
file  amendments  thereto.  Such  Schedule  14D-1  and any  amendments  thereto,
including exhibits, may be examined at, and copies may be obtained from, the SEC
(but  not the  regional  offices  of the  SEC) in the  manner  set  forth  under
"Available Information."

                       CERTAIN FEDERAL INCOME TAX MATTERS

         Orion has been advised by its counsel that tendering  shareholders  who
exchange  their  Shares for the Offer  Consideration  pursuant to the Offer will
recognize gain or loss on the exchange  measured by the  difference  between the
cash plus the fair market value  (determined on the date of the exchange) of the
Orion Common Stock  received and the holder's  basis in the Shares.  Any gain or
loss will be a long-term  capital gain or loss if the holder has held the Shares
for more than one year,  provided that any gain will be a "mid-term gain" if the
holder has held the Shares for more than one year but not more than 18 months.

         The  shareholders of Guaranty should be aware that this discussion does
not deal with all  Federal  income tax  considerations  that may be  relevant to
particular shareholders of Guaranty in light of their particular  circumstances,
such as shareholders who are dealers in securities, shareholders who are subject
to the  alternative  minimum  tax  provisions  of  the  Code,  foreign  persons,
tax-exempt   entities,   insurance   companies,   financial   institutions   and
shareholders  who  acquired  their  shares  in  compensatory  transactions.   In
addition,  the following discussion does not address the tax consequences of the
Offer  under  foreign,  state,  or  local  tax laws or the tax  consequences  of
transactions  effectuated  prior  to or  after  the  Offer,  including,  without
limitation,  transactions  in which shares of Guaranty Common Stock are acquired


                                       58
<PAGE>

or in which  shares of Orion  Common  Stock  are  disposed,  and the  discussion
assumes  that the  Shares  are  capital  assets  in the  hands  of the  holders.
Accordingly,  SHAREHOLDERS  OF  GUARANTY  ARE  URGED TO  CONSULT  THEIR  OWN TAX
ADVISORS  AS  TO  THE  SPECIFIC  CONSEQUENCES  OF  THE  OFFER  AND  ANY  RELATED
TRANSACTIONS,  INCLUDING THE APPLICABLE  FEDERAL,  STATE, LOCAL, AND FOREIGN TAX
CONSEQUENCES  TO THEM  OF THE  OFFER  AND  ANY  RELATED  TRANSACTIONS  IN  THEIR
PARTICULAR CIRCUMSTANCES.

                  CERTAIN RELATIONSHIPS; RELATED TRANSACTIONS;
                          INTERESTS OF CERTAIN PERSONS

         As indicated  elsewhere in this Prospectus,  Orion and its subsidiaries
have entered into several  agreements  with Guaranty and its  subsidiaries.  See
"Special  Factors --  Background  of the Offer" and "--  Reasons  for the Offer;
Purpose and Structure of the  Transaction;  Plans After the Offer."  Pursuant to
the Shareholder Agreement between Orion and Guaranty,  Messrs.  Becker, Papa and
Shepherd,  directors of Orion, have been nominated as directors of Guaranty, and
the Shareholder  Agreement also provides that Orion has the right on up to three
occasions to require  Guaranty to register under the Securities Act Shares owned
by Orion and its  wholly-owned  subsidiaries,  which  right  expires in November
1997. "Special Factors -- Background of the Offer -- Guaranty Board Composition;
Orion  Nominees."  In  addition,  Guaranty has agreed to use its best efforts to
include such Shares in any underwritten  public offering of its Shares under the
Securities  Act and to pay  all  expenses  in  connection  with  the  first  two
registrations.  In 1994 the Shareholder  Agreement was amended to provide for an
increase in the maximum number of directors,  including directors independent of
management, and in March 1995 was amended to increase the number of directors to
eleven.

         Most state  insurance  codes  require  transactions  between a licensed
insurance  company and its affiliates to be fair and reasonable.  In the case of
certain material  transactions,  an insurance company must obtain prior approval
of the transaction from the appropriate state insurance department.  Reinsurance
agreements,  tax  sharing  agreements,   loans,  guarantees,   sales  and  other
transactions of a material size, as well as management  service and cost sharing
agreement  must  similarly  be  approved.  In the  ordinary  course of business,
Guaranty's  insurance  subsidiaries  reinsure certain risk with other companies.
Such  arrangements  serve to limit their  maximum  loss on large  risks.  To the
extent that any reinsuring company is unable to meet its obligations, Guaranty's
insurance  subsidiaries  would not be relieved of their  liabilities.  For 1994,
Guaranty National  Insurance  Company ("GNIC") and Landmark  American  Insurance
Company ("LAIC"), wholly-owned subsidiaries of Guaranty, were parties to an 100%
reinsurance agreement with an Orion subsidiary. Premiums written and ceded under
this  agreement  are  included  in premiums  written as  reported in  Guaranty's
financial   statements  and  were  $643,000  for  1994.   Guaranty's   insurance
subsidiaries  were paid  $14,000 in fees and  reimbursed  $1,000 for expenses in
conjunction with this reinsurance agreement.  Also during 1994, GNIC was a party
to reinsurance  agreements with Orion insurance  subsidiaries  pursuant to which
GNIC  assumed  business  written  through  affiliates  totaling  $30,921,000  in
premium.  GNIC  paid to  Orion's  insurance  subsidiaries  $666,000  in fees and
reimbursed   $774,000  of  actual   expenses   incurred  by  Orion's   insurance
subsidiaries in conjunction with this reinsurance agreement.  For 1995, GNIC and


                                       59
<PAGE>

LAIC  were  parties  to a 100%  reinsurance  agreement  with an Orion  insurance
subsidiary.  Premiums  written and ceded under this  agreement  are  included in
premiums  written  as  reported  in  Guaranty's  financial  statements  and were
$152,000 for 1995.  Insurance  subsidiaries of Guaranty were paid $5,000 fees in
conjunction with this reinsurance agreement.  Also during 1995, GNIC was a party
to reinsurance  agreements with Orion insurance  subsidiaries  pursuant to which
GNIC  assumed  business  written  through  affiliates   totaling  $9,495,000  in
premiums.  GNIC paid to the Orion  insurance  subsidiaries  $160,000 in fees and
reimbursed   $178,000  of  actual   expenses   incurred  by  Orion's   insurance
subsidiaries in conjunction with this reinsurance agreement.  For 1996, GNIC and
LAIC  were  parties  to a 100%  reinsurance  agreement  with an Orion  insurance
subsidiary.  Premiums  written and ceded under this  agreement  are  included in
premiums written as reported in Guaranty's financial statements and were $15,000
for  1996.  Insurance  subsidiaries  of  Guaranty  were  paid  $1,000 in fees in
conjunction with this reinsurance agreement.  Also during 1996, GNIC was a party
to reinsurance  agreements with Orion insurance  subsidiaries  pursuant to which
GNIC  assumed  business  written  through  affiliates  totaling  $15,673,000  in
premiums.  GNIC paid to the Orion  insurance  subsidiaries  $298,000 in fees and
reimbursed   $309,000  of  actual   expenses   incurred  by  Orion's   insurance
subsidiaries in conjunction with this reinsurance agreement.

         A subsidiary  of Orion is an agent for Guaranty  pursuant to Guaranty's
standard agency contract. During 1995, this agency produced $411,000 in premiums
and was paid  $72,000 in  commissions  and during  1996,  produced  $436,000  in
premiums and was paid $85,000 in commissions.  Guaranty and Orion expect similar
premium  production and  commissions in 1997.  During 1994, this agency produced
$516,000 in premiums and was paid $90,000 in commissions.

         During  1995,   Guaranty's  2003  Notes  in  the  principal  amount  of
$20,896,000, were converted by Orion's subsidiaries into 1,326,128 Shares. Total
interest paid by Guaranty on the 2003 Notes in 1995 to Orion's  subsidiaries was
$1,122,000.  See "The  Offer  --  Background  of the  Offer."  Also in 1995,  in
connection  with  the  Viking  Holdings  acquisition  financing,  Orion  made  a
commitment  for a  $21,000,000  bridge loan to Guaranty.  The loan was not drawn
down,  but  Guaranty  paid a  $210,000  commitment  fee to Orion at the time the
commitment was executed.

         Guaranty and Orion have entered into an investment management agreement
pursuant to which the investment  portfolio of Guaranty  (other than  short-term
investments  and a portion  of  equity  securities)  is  managed  by  investment
managers of Orion under the direction and supervision of Guaranty and subject to
Guaranty's  investment policies.  For its investment  management services,  fees
were paid to Orion at a rate of $550,000  per year from 1993  through July 1995,
at which time they were  increased to a rate of $650,000 per year in recognition
of the  additional  investment  balances  resulting  from  the  Viking  Holdings
acquisition.  Orion received $650,000 in fees from Guaranty under this agreement
in 1996. The agreement  continues in effect for annual periods unless terminated
by either party upon 90 days prior written notice.

         During 1990, GNIC entered into a loan participation  agreement pursuant
to which DPIC borrowed approximately $9 million from affiliates. The loan, which


                                       60
<PAGE>

was secured by a  leasehold  deed of trust on an office  building  in  Monterey,
California  owned and  primarily  occupied by DPIC,  matured in  November  1995.
GNIC's  proportionate shares of this loan was $3,700,000 or 41.4%. GNIC received
quarterly interest payments at a rate of 11% per year.  Interest earned for 1994
was  $407,000  and for  1995 was  $355,000,  and in  November  1995 the loan was
repaid.

         Effective July 2, 1996,  Guaranty was included in Orion's  consolidated
federal income tax return and is covered by income tax sharing  agreements under
which Guaranty  computes its current  federal income tax liability on a separate
return basis and pays Orion any taxes due on this basis.

         Except as described above or in "Securities Ownership" and elsewhere in
this Prospectus,  neither Orion, nor any direct or indirect  subsidiary of Orion
nor,  to the best  knowledge  of  Orion,  any of the  persons  listed in Annex I
hereto,  has any contract,  arrangement,  understanding or relationship with any
other person with respect to any  securities  of  Guaranty,  including,  but not
limited to, contracts, arrangements,  understandings or relationships concerning
the  transfer  or  voting of such  securities,  joint  ventures,  loan or option
arrangements, puts or calls, guaranties of loans, guaranties against loss or the
giving or withholding of proxies, consents or authorizations.

         Except as set forth in this  Prospectus,  since January 1, 1994,  there
have been no transactions  that would be required to be reported under the rules
of the SEC between Orion or, to the best knowledge of Orion,  any of the persons
listed  in  Annex I  hereto,  and  Guaranty  or any of its  executive  officers,
directors or affiliates.

         Except as described  above or in "Special  Factors -- Background of the
Offer " and "Securities Ownership" or as set forth elsewhere in this Prospectus,
since  January  4,  1995,  there have been no other  contacts,  negotiations  or
transactions  between Orion or any of its subsidiaries or, to the best knowledge
of Orion,  any of the  persons  listed in Annex I hereto,  and  Guaranty  or its
directors,  executive  officers  or  affiliates,  or between any  affiliates  of
Guaranty,  or  between  Guaranty  or any of its  affiliates  and any  person not
affiliated  with  Guaranty  and  who  would  have  a  direct  interest  therein,
concerning  a merger,  consolidation  or  acquisition,  a tender  offer or other
acquisition of securities of Guaranty,  an election of directors of Guaranty, or
a sale or other transfer of a material amount of assets.

         Except  as set forth  herein,  Orion  knows of no member of  Guaranty's
management  or Board of Directors  who has  interests in the Offer which are not
identical to those of other holders of the Shares.

         As indicated  under  "Available  Information,"  Orion is subject to the
information filing requirements of the Exchange Act and in accordance  therewith
files reports,  proxy statements and other  information with the SEC relating to
its  business,  financial  condition  and  other  matters.  Information,  as  of
particular dates, concerning Orion's directors and officers, their remuneration,
options  granted to them,  the principal  holders of Orion's  securities and any
material  interest of such  persons in  transactions  with Orion is disclosed in

                   SELECTED BUSINESS AND FINANCIAL INFORMATION
                              WITH RESPECT TO ORION

BUSINESS OF ORION

         OVERVIEW.  Orion is an insurance  holding company.  It has the ability,
through its subsidiaries and investments in other insurance companies,  to write
almost all types of property and casualty  insurance  nation-wide and throughout
Canada.  However,  it does not sell all types of insurance.  Its  operations are
highly  specialized.  Orion  underwrites  and  sells the  following  specialized
insurance products and services:

- -    workers compensation products and related services through EBI companies;

- -    professional  liability coverage for architects,  engineers,  environmental
     consultants, lawyers and accountants through DPIC Companies;

- -    special  property and  casualty  insurance  programs  tailored to the risks
     associated with selected types of businesses through Connecticut Specialty;

- -    nonstandard automobile insurance for individuals and businesses, as well as
     other  property  insurance  through  its  approximately  81%  ownership  of
     Guaranty and its subsidiaries; and

- -    underwriting  management of insurance pools focusing on ocean cargo, inland
     marine and commercial  property  coverage  through Wm. H. McGee & Co., Inc.
     ("McGee").

         At the present time Orion owns approximately 81% of Guaranty.  Guaranty
and its subsidiaries sell specialty  property and casualty  insurance  coverages
which are not readily available in traditional insurance markets. Orion includes
Guaranty in its consolidated federal income return. However, Guaranty remains an
independent  public  company with its common stock listed on the NYSE.  Three of
Guaranty's ten member board of directors also serve on Orion's board.

         In 1995,  Orion purchased McGee, an insurance  underwriting  management
firm.  McGee  underwrites  ocean cargo,  inland marine and  commercial  property
insurance on behalf of the group of insurance companies it represents, including
two of Orion's  subsidiaries,  Security  Insurance  Company of Hartford  and The
Connecticut  Indemnity  Company.  McGee has been in business for over 109 years,
and has  represented  subsidiaries  of Orion for over 100 years.  McGee provides
practically all services related to the insurance business which it underwrites.
For example,  it issues  policies on behalf of its pool members,  settles claims
and places  reinsurance.  McGee  oversees an insurance pool in the United States
and one in Canada.  Orion's rate of  participation  in McGee's U.S. pool in 1996


                                       62
<PAGE>

was 37% and has increased to 52% in 1997. Orion's  participation rate in McGee's
Canadian pool in 1996 was approximately 49%, which increased to 60.5% in 1997.

         In November 1996, Orion exited the assumed reinsurance business when it
sold the ongoing operations of its subsidiary, Security Reinsurance Company. The
purchaser was Hartford Fire  Insurance  Company acting for Hart Re, the Hartford
Insurance  Group's  reinsurance  operation.  As a result of the  sale,  Security
Reinsurance  Company  discontinued  writing  business  and  became  an  inactive
company.  Orion kept the reserves of approximately  $108 million with respect to
this  operation's  outstanding  business  and it will manage the  settlement  of
claims arising out of that business.

         Orion has also  invested in Intercargo  Corporation  a publicly  traded
insurance  holding  company.  Orion  owns  approximately  24.8%  of  its  stock.
Intercargo subsidiaries are insurance companies that specialize in international
trade  and  transportation  coverages.  Intercargo  operates  as an  independent
company and Orion nominates one member of its  seven-member  board of directors.
Orion has agreed with  Intercargo  that,  until  December 31, 1998,  it will not
increase its ownership above 35% without Intercargo's approval.

         Orion owns  insurance  companies,  brokerage  companies  and  insurance
management  and service  companies.  Those  companies  have licenses to transact
business  nationwide  and in all Canadian  provinces.  In general Orion does not
sell  its  insurance  products  directly  to its  policyholders.  Orion  obtains
substantially all its business through independent insurance agents and brokers.
Orion has  approximately  3,250 employees,  including 1,030 Guaranty  employees.
Substantially  all its  employees  work in its  insurance  or  insurance-related
operations.

         Orion was incorporated in the State of Delaware in 1960, and all of its
wholly-owned   insurance   subsidiaries   are   incorporated  in  the  State  of
Connecticut.  Guaranty has insurance  subsidiaries which are incorporated in the
states of California, Colorado, Oklahoma, Texas and Wisconsin. Orion's principal
executive  offices are located at 9 Farm Springs Road,  Farmington,  Connecticut
06032 and the telephone number is (860) 674-6600.

         For a more detailed description of the business of Orion,  reference is
made to "Item 1. Business" in the Orion 1996 10-K, which is incorporated  herein
by reference.

         PROPERTIES OF ORION.  For a detailed  description  of the properties of
Orion reference is made to "Item 2. Properties" in the Orion 1996 10-K, which is
incorporated herein by reference.

         GOVERNMENT REGULATION. The operations of Orion and its subsidiaries and
affiliates  are subject to state  insurance laws and  regulations  requiring the
licensing of insurance agents, brokers, reinsurance intermediaries,  reinsurance
underwriting  managers,  and  managing  general  agents and  regulating  certain
aspects of their business. These laws and regulations are intended primarily for
the  protection  of  policyholders,  rather than  shareholders  of the  licensed
entities,  and may include  requirements  for certain  provisions  in  contracts
entered into between Orion and various  insurers or  reinsurers,  certain record


                                       63
<PAGE>

keeping and reporting requirements, advertising and business practice rules, and
other matters.  Orion's business  depends on obtaining and maintaining  licenses
and  approvals  pursuant  to  which  it  operates,  as well as  compliance  with
pertinent  regulations.  There can be no assurance given that Orion has all such
required  licenses,  approvals  or complying  contracts  or that such  licenses,
approvals or complying  contracts  can always be obtained or  continued.  In all
jurisdictions,  the applicable  laws and regulations are subject to amendment or
interpretation by regulatory authorities. Generally, such authorities are vested
with  relatively  broad  discretion  to grant,  renew and  revoke  licenses  and
approvals,  and to implement regulations.  Licenses may be denied or revoked for
various  reasons,  including the violation of regulations,  conviction of crimes
and  the  like.  In  some  instances,  Orion  follows  practices  based  on  its
interpretations,  or those that it  believes  may be  generally  followed by the
industry,  which  may be  different  from the  requirements  or  interpretations
promulgated  from  time to  time by  regulatory  authorities.  Accordingly,  the
possibility  exists that Orion may be precluded or  temporarily  suspended  from
carrying on some or all of its  activities  or  otherwise  penalized  in a given
jurisdiction.  Such  preclusion  or suspension  could have a materially  adverse
effect on the business and results of operations of Orion.

backgrounds  of the  executive  officers  and  directors  of  Orion  as  well as
information regarding executive  compensation,  security ownership of management

10, 11, 12 and 13 of the 1996 10-K, which are incorporated herein by reference.

GUARANTY  SHAREHOLDERS  ARE URGED TO OBTAIN  CURRENT  MARKET  QUOTATIONS FOR THE
SHARES OF ORION COMMON STOCK.

         Orion declared cash dividends to its  shareholders of $.43 per share in
1995 and $.515 per share in 1996.  Declaration and payment of cash dividends has
been  dependent on Orion's  earnings  levels,  capital  requirements,  financial
condition,  loan  covenants,  and other related  factors deemed  relevant by the
Orion Board. In 1997,  Orion has declared and paid dividends to its shareholders
as follows:  $0.14 per share  (paid on April 1, 1997),  $0.16 per share (paid on
July 1, 1997) and $0.16 per share (to be paid on October 1, 1997).

                   SELECTED BUSINESS AND FINANCIAL INFORMATION
                            WITH RESPECT TO GUARANTY

BUSINESS OF GUARANTY

         GENERAL.   Guaranty  and  its  subsidiaries   ("Guaranty")  principally
underwrite and sell specialty  property and casualty  insurance  coverages which
are not  readily  available  in  traditional  insurance  markets.  Personal  and
commercial  automobile insurance accounted for approximately 84% of Guaranty net
premiums   written  during  1996.   Guaranty's   personal  lines  business  unit
principally writes nonstandard  automobile  insurance for individuals who do not
qualify for preferred or standard  insurance  because of their payment  history,
driving record, age, vehicle type, or other factors, including market conditions
for standard  risks.  Guaranty  also  markets  collateral  protection  business.
Guaranty's  commercial  lines unit  principally  writes  nonstandard  commercial
automobile  coverage.  However,  approximately 29% of the total commercial lines
unit net premiums  written  consists of standard  commercial  coverage.  Typical
risks include local and intermediate trucking, garages, used car dealers, public
and private livery,  and artisan  contractors.  Other commercial lines coverages
include property,  general  liability,  umbrella and excess insurance,  standard
multi-peril packages and other coverages.

         Nonstandard  risks  generally  involve  a  potential  for  poor  claims
experience  because of increased risk exposure.  Premium levels for  nonstandard
risks are substantially higher than for preferred or standard risks. In personal
lines,  Guaranty's loss exposure is limited by the fact that nonstandard drivers
typically  purchase low liability limits,  often at a state's statutory minimum.
The  nonstandard  insurance  industry  is also  characterized  by the  insurer's
ability to minimize its exposure to  unprofitable  business by effecting  timely
changes in premium rates and policy terms in response to changing loss and other
experiences.  In those states where prior approval for rate changes is required,
Guaranty has generally gained approval in a timely manner.  Guaranty also writes
business  in states  where  prior  approval to  effectuate  rate  changes is not
required.  Generally,  nonstandard risks written by Guaranty require specialized
underwriting, claims management, and other skills and experience.

         Guaranty  historically  has focused its  operations in the  nonstandard
markets where it expects that its expertise and market position will allow it to
generate an  underwriting  profit.  An  indicator  of  underwriting  profit is a
generally accepted  accounting  principles  ("GAAP") combined ratio of less than
100%. During 1996, Guaranty's GAAP combined ratio was 100.1%, and in four of the
last six years Guaranty has achieved a GAAP combined ratio of less than 100%.

         In July 1995,  Guaranty  acquired Viking Insurance Company of Wisconsin
("Viking"),   which  is  a  property  and  casualty  insurance  company  writing
non-standard personal automobile  insurance.  The Viking acquisition has enabled
Guaranty to change its business mix, expand its personal lines business into new
territories,  strengthen  personal  lines market share in existing  states,  and
provide   flexibility  in  marketing   Guaranty's   personal   lines   products.
Additionally,  Viking controls Viking County Mutual Insurance Company ("VCM"), a


                                       66
<PAGE>

Texas mutual organization. As a result, Guaranty and its affiliates receive 100%
reinsurance services in the state of Texas from VCM.

         In 1995, the personal lines business was written through two divisions:
the  Guaranty  division  and  Viking.   However,  in  1996  Guaranty  management
integrated the Guaranty and Viking  personal  lines  divisions into one personal
lines business unit. As a result,  personal lines  information will no longer be
delineated by division.

         The  personal  lines  business  unit  provides   nonstandard   personal
automobile coverage, primarily in the state of California and the Rocky Mountain
and Pacific Northwest regions. This coverage is sold through approximately 8,900
independent agents located in 28 states. In addition, this unit markets business
through three general agents.

         Overall,  Guaranty seeks to distinguish  itself from its personal lines
competitors by providing a superior,  highly  automated and responsive  level of
service  to its  agents and  insureds.  In  addition  to high  quality  service,
Guaranty's  personal  lines  business unit provides ease of payment for insureds
through low monthly installments.

         Prior to 1996,  the commercial  lines business was written  through the
commercial  standard,  commercial  general and commercial  specialty  divisions.
However,  during 1996,  Guaranty's management evaluated the commercial specialty
and general divisions and decided that  reorganizing  these two divisions into a
contracts  and  brokerage  division and a separate  programs  department,  would
enable  Guaranty to operate more  efficiently and to better serve its respective
markets. The commercial standard division will, however,  remain separate.  As a
result of this reorganization  decision, the financial results of the commercial
lines unit will be discussed in total.

         The nonstandard  commercial lines business  primarily offers commercial
coverages for transportation risks, regional programs, specialized coverages for
small to  medium-sized  businesses  and umbrella  coverages for a broad range of
organizations.  This  nonstandard  commercial  business  is  written  through 69
general agents and various brokers  throughout the United States except for some
Northeastern  states.  These general  agents  specialize in particular  types of
risks and/or  geographic  locations.  Guaranty's  objective for its  nonstandard
commercial business is to maintain long-term,  mutually profitable relationships
with a small  number of select  general  agents who follow  strict  underwriting
guidelines.

         Colorado Casualty Insurance Company ("CCIC"),  an insurance  subsidiary
of Guaranty,  writes primarily standard  commercial lines business.  CCIC writes
small, standard commercial package policies. The standard commercial business is
primarily  written in the Rocky Mountain  region,  but has recently  expanded to
states outside of the Rocky Mountain  region,  mainly in the Southeast Region of
the  United  States.  CCIC has been  successful  in  serving  a niche  market of
approximately  600 small to medium  retail  agents.  In addition,  CCIC utilizes
seven general agents as branch offices.  The standard  business produced by CCIC
complements the nonstandard focus of the commercial lines unit.



                                       67
<PAGE>

         Guaranty  also  writes  collateral  protection   insurance,   primarily
insuring  automobiles  pledged as security  for loans for which the borrower has
not maintained physical damage coverage as required by the lender. This business
is written through 34 general agents across the country and in the  Commonwealth
of Puerto Rico.

         Personal lines,  commercial lines and collateral protection represented
48%, 37%, and 15%,  respectively,  of Guaranty's  gross premiums  written during
1996.

         Guaranty and Orion  concluded by early 1997 that the  nonstandard  auto
insurance business would soon undergo a consolidation and that future success in
that business  would  benefit from a broader base and range of  operations  than
Guaranty's.  Accordingly, Guaranty's and Orion's senior management began to plan
for the strategic  growth of Guaranty,  both internally and by  acquisition.  At
various  times,  Guaranty  has made,  and  currently  has  under  consideration,
proposals  to  acquire  additional  business  or  lines  of  business.   In  the
discussions of Guaranty's  strategic  alternatives,  it has recognized  that the
cost of  acquisitions,  together  with the cost of  infrastructure  and  systems
improvements  needed to support Guaranty's  strategic plans, might be beyond the
capital-raising capability of Guaranty unaided by support from Orion.

         A.M. Best Company  currently  rates  Guaranty and its  subsidiaries  "A
(Excellent)" and Viking and its affiliate  "A-(Excellent)" A.M. Best ratings are
based upon factors of concern to  policyholders,  agents and  reinsurers and are
not primarily directed toward the protection of investors.

         PROPERTIES.  Guaranty's operations are principally located in a 150,000
square  foot  facility  located in  Englewood,  Colorado,  a 64,000  square foot
building located in Madison,  Wisconsin, a 23,000 square foot building in Salem,
Oregon and a 35,000  square foot  facility in  Freeport,  Illinois.  All four of
these  facilities are owned by Guaranty,  are currently  adequate for Guaranty's
needs and are anticipated to remain adequate for future needs.

     certain  partners  of N&B in their own  personal  securities  accounts  and
     55,000 shares held by the Neuberger & Berman Profit Sharing Retirement Plan
     ("N&B Plan") for the benefit of the N&B Plan's participants who are current
     and former N&B employees and partners.  N&B disclaims  beneficial ownership
     of such shares owned directly by N&B partners and the N&B Plan.

(2)  Southeastern  Asset  Management,  Inc.  ("Southeastern")  reported  in  its
     initial Schedule 13G, filed with the SEC on February 10, 1997, that it held
     an aggregate of 860,000  shares of Orion Common Stock in its  discretionary
     and non-discretionary  accounts, with sole voting power over 670,800 shares
     of Common Stock,  shared voting power over 165,000 shares,  no voting power
     as to 25,000 shares,  sole dispositive power over 695,800 shares and shared
     dispositive power over 165,000 of such shares.  Southeastern  reported none
     of the  shares  are  owned  by it and  that it holds  such  shares  for its
     investment advisory clients.

(3)  Includes 106,251 shares which represent the group's proportionate  interest
     in shares held by the Trustee under Orion's  Savings and Retirement Plan as
     of December 31, 1996,  259,315 shares which the group has rights to acquire
     as of June 30, 1997 pursuant to the  Performance  Incentive Plan and 28,178
     shares of Restricted  Stock held  pursuant to the terms of the  Performance
     Incentive  Plan. As of December 31, 1996, the Savings and Retirement  Plan,
     as a whole,  held 804,119 shares  (5.84%) of Orion Common Stock.  Shares of


                                       70
<PAGE>

     Orion Common Stock held by the Savings and Retirement  Plan Trustee will be
     voted in accordance with the instructions of the employee for whose account
     the shares are held. If no such instructions are received,  the Savings and
     Retirement  Plan Trustee will vote such shares in the same proportion as it
     votes   shares  for  which  it  does   receive   instructions   from  other
     participating employees.

         Except as described  above,  in "Special  Factors --  Background of the
Offer," or as set forth  elsewhere  in this  Prospectus  and in Annex II hereto,
neither Orion,  nor to the best knowledge of Orion, any of the persons listed in
Annex I hereto or any associate or majority-owned  subsidiary of Orion or any of
the  persons so listed,  beneficially  owns or has a right to acquire any of the
Shares,  and neither Orion nor to the best knowledge of the Orion, any executive
officer,  director or  majority-owned  subsidiary of any of the  foregoing,  has
effected any transaction in the Shares during the past 60 days.

                       DESCRIPTION OF ORION CAPITAL STOCK

GENERAL

         The authorized  capital stock of Orion consists of 50,000,000 shares of
Common Stock and 5,000,000  shares of preferred  stock,  of which 125,000 shares
have  been  designated  as  Series B  Junior  Participating  Preferred  Stock in
connection with Orion's Shareholders Rights Plan (see below). As of September 1,
1997, there were issued and outstanding  27,537,155 shares of Orion Common Stock
and options to purchase 1,015,666 shares of Orion Common Stock.

         The holders of outstanding shares of Orion Common Stock are entitled to
receive dividends out of assets legally available  therefor at such times and in
such  amounts  as the  Orion  Board  may  from  time  to  time  determine.  Each
shareholder is entitled to one vote for each share of Orion Common Stock held on
all  matters  submitted  to a vote of  shareholders.  Cumulative  voting for the
election  of  directors  is  not  provided  for  in  the  Orion  Certificate  of
Incorporation,  which means that the  holders of a majority of the shares  voted
can elect all of the directors then standing for election. Orion Common Stock is
not  entitled  to  preemptive  rights  and  is  not  subject  to  conversion  or
redemption.  Upon  liquidation,  dissolution or winding up of Orion,  the assets
legally  available for  distribution to shareholders are  distributable  ratably
among the holders of Orion Common Stock  outstanding  at that time after payment
of other claims of creditors.  Each outstanding  share of Orion Common Stock is,
and all shares of Orion  Common  Stock to be issued in the Offer will be,  fully
paid and nonassessable.

RESALE OF ORION COMMON STOCK

         The shares of Common  Stock of Orion  offered by this  Prospectus  have
been registered under the Securities Act, thereby allowing Guaranty shareholders
who are not  "affiliates"  of Guaranty or Orion (as defined under the Securities
Act, but generally  including  directors,  certain executive officers and 10% or
more  shareholders  of  Guaranty  or Orion) to trade  them  freely  and  without
restriction.

DELAWARE'S ANTITAKEOVER LAW

         Orion is  subject to the  provisions  of  Section  203 of the  Delaware
General  Corporation  Law (the  "DGCL")  ("Section  203")  regulating  corporate
takeovers.  Section 203 prevents certain Delaware corporations,  including those
whose  securities  are  traded  on  the  NYSE,  from  engaging,   under  certain
circumstances,  in a "business  combination" (which includes a merger or sale of
more than 10% of the corporation's assets) with any "interested  shareholder" (a
shareholder who owns 15% or more of the corporation's outstanding voting shares)
for three years following the date that such  shareholder  became an "interested
shareholder." See "Comparison of the Rights of Holders of Orion Common Stock and
Guaranty  Common Stock -- Antitakeover  Provisions." A Delaware  corporation may
"opt out" of Section 203 with an express  provision in its original  certificate
of  incorporation or in a bylaws'  amendment  approved by at least a majority of
the  outstanding  voting shares.  Orion has not "opted out" of the provisions of
Section 203.

SHAREHOLDERS RIGHTS PLAN

         Under the Orion  Shareholders  Rights Plan adopted as of September  16,
1996 (the "Plan"),  each holder of a Right is entitled to buy one hundredth of a
share of Junior Participating Preferred Stock. The rights will be exercisable if
an acquiror gains a 15% or greater beneficial ownership interest in Orion Common
Stock by either a purchase,  a tender offer or an exchange offer. If an acquiror
gains such 15% or greater beneficial  ownership other than on fair and favorable
terms to all stockholders, each Right not owned by such acquiror will enable the
holder to purchase,  at an initial  exercise  price as provided  under the Plan,
Orion Common Stock (or other consideration in some circumstances) having a value
of twice the Right's exercise price. In addition,  if, following the acquisition
of 15% or more of Orion  Common  Stock,  Orion is  involved in a merger or other
business  combination   transaction  in  which  common  shares  are  changed  or
converted,  or Orion  sells 50% or more of its  assets,  each Right that has not
previously  been exercised  will entitle its holder to purchase,  at the Right's
then current exercise price,  common shares of such other company having a value
of twice the Right's exercise price.  Orion will generally be entitled to redeem
the Rights at $.01 per Right at any time until, unless otherwise  extended,  the
10th day following public announcement that 15% or more of its outstanding Orion
Common Stock is to be acquired by any person.

TRANSFER AGENT AND REGISTRAR

         The Transfer  Agent and Registrar for Orion Common Stock is ChaseMellon
Shareholder Services, L.L.C.

LISTING

         Orion Common Stock is listed on the NYSE under the trading symbol "OC."
The obligation of Orion to consummate the Offer is subject to the condition that
the Orion Common Stock to be issued to Guaranty  shareholders in connection with
the Offer,  shall have been  approved  for listing on the NYSE,  subject only to
official notice of issuance. That approval was obtained on              , 1997.

                       COMPARISON OF THE RIGHTS OF HOLDERS
                 OF ORION COMMON STOCK AND GUARANTY COMMON STOCK

         The following  summary compares certain rights of the holders of Shares
to the  rights of the  holders of Orion  Common  Stock.  The rights of  Guaranty
shareholders are governed  principally by the Colorado Business  Corporation Act
(the "CBCA"),  the Guaranty Charter and the Guaranty By-Laws.  Upon consummation
of the Offer,  such  shareholders  will become holders of Orion Common Stock and
their rights will be governed principally by the DGCL, the Orion Charter and the
Orion By-Laws.

         The  statements  set forth under this heading with respect to the CBCA,
the DGCL, the Guaranty Articles of Incorporation (the "Guaranty  Charter"),  the
Guaranty By-Laws,  the Orion Restated  Certificate of Incorporation  (the "Orion
Charter"), and the Orion By-Laws (copies of which have been filed as Exhibits to
the  Registration  Statement)  are  brief  summaries  and do not  purport  to be


                                       73
<PAGE>

complete;  such  statements are subject to the detailed  provisions of the CBCA,
the DGCL, the Guaranty Charter, the Guaranty By-laws, the Orion Charter, and the
Orion Bylaws.

DIVIDEND RIGHTS

         The rights of Guaranty shareholders and Orion shareholders with respect
to the receipt of dividends are  substantially  the same.  See  "Description  of
Orion Capital Stock -- General."

         Under  the  CBCA,  a  corporation   may  make  a  distribution  to  its
shareholders  unless,  after  giving  effect  to  such  distribution,   (i)  the
corporation  would not be able to pay its debts as they  become due in the usual
course of business,  or (ii) the  corporation's  total assets would be less than
the sum of its total  liabilities  plus  (unless the  articles of  incorporation
permit otherwise) the amount that would be needed, if the corporation were to be
dissolved at the time of the  distribution,  to satisfy the preferential  rights
upon dissolution of shareholders whose preferential rights are superior to those
receiving the distribution.

         Under the DGCL, a corporation may pay dividends out of surplus (defined
as the  excess,  if any,  of net assets  over  capital)  or, if no such  surplus
exists,  out of its net profits for the fiscal year in which such  dividends are
declared and/or for its preceding  fiscal year,  provided that dividends may not
be paid out of net profits if the capital of such  corporation  is less than the
aggregate amount of capital  represented by the outstanding stock of all classes
having a preference upon the distribution of assets.

VOTING RIGHTS

         Each share of  Guaranty  Common  Stock and each  share of Orion  Common
Stock entitles holders thereof to one vote on each matter submitted to a vote of
such  holders.  Neither the holders of Shares nor the holders of shares of Orion
Common Stock have cumulative voting rights in the election of directors.

         Under the CBCA, directors are elected by a plurality of the votes cast.
Pursuant to the  Guaranty  By-laws,  other  matters  submitted  to a vote of the
Guaranty shareholders require for approval the affirmative vote of a majority of
the shares  represented  at the  meeting  and  entitled  to vote on the  subject
matter.  However,  the  transitional  provisions of the CBCA impose a two-thirds
voting requirement on certain actions, including actions to approve an amendment
to the  Guaranty  Articles of  Incorporation  and actions to approve a merger or
plan of share exchange.  See "--Amendment to Charter Document" and "Approvals of
Mergers and Asset Sales." For information regarding the comparable voting rights
of the holders of Orion Common Stock, see "Description of Orion Stock--General."

DIRECTORS

         NUMBER AND ELECTION OF DIRECTORS;  REMOVAL. Under both the CBCA and the
DGCL,  the charter  document,  and the by-laws of a corporation  may specify the
number of directors.  The Guaranty By-Laws provide that the Guaranty Board shall
consist of not fewer than three nor more than eleven directors, each serving for


                                       74
<PAGE>

a term of one year, with the Guaranty shareholders and the Guaranty Board having
the authority to determine the exact number of directors.  Any vacancy occurring
in the  Guaranty  Board or  newly  created  directorship  may be  filled  by the
affirmative vote of the remaining  directors.  The Guaranty By-Laws also provide
that  directors  may be removed  from office as provided by the CBCA.  Under the
CBCA, the shareholders may remove a director under limited  circumstances either
with or without cause.

         Guaranty has contractually  agreed with Orion that Orion shall have the
right to nominate three  directors so long as it owns at least 30% of the Shares
and at least two  directors  so long as it owns at least 20% of the  Shares  See
"The Offer -- Background of the Offer."

         The Orion Charter  provides that the number of directors shall be fixed
and may be altered as provided in the by-laws. The By-laws of Orion provide that
there  shall be not  fewer  than 5 nor more  than 14  directors,  with the exact
number to be fixed by the  Board of  Directors.  Any  vacancy  or newly  created
directorship  may be  filled  by  the  affirmative  vote  of a  majority  of the
remaining directors. Directors may be removed from office as provided under DGCL
which provides that the affirmative  vote of a majority of the  shareholders may
remove directors under certain circumstances.

         FIDUCIARY  DUTIES OF DIRECTORS.  Under the CBCA, a director is required
to perform his or her duties as a director,  including the duties as a member of
any committee of the board of directors  upon which such director may serve,  in
good faith,  with the care that an ordinarily  prudent person in a like position
would use under similar  circumstances and in a manner such director  reasonably
believes to be in the best interests of the corporation.

         Under the DGCL,  the business and affairs of a corporation  are managed
by or under the direction of its board of directors. In exercising their powers,
directors  are  charged  with  fiduciary  duty to protect the  interests  of the
corporation and to act in the best interests of its shareholders. In recognition
of  the  managerial   prerogatives  granted  to  the  directors  of  a  Delaware
corporation,  Delaware law presumes  that, in making a business  decision,  such
directors are  disinterested  and act on an informed basis, in good faith and in
the  honest  belief  that the  action  taken was in the best  interests  of such
corporation, which presumption is known as the "business judgment rule." A party
challenging the propriety of a decision of a board of directors bears the burden
of rebutting the  applicability of the presumption of the business judgment rule
by demonstrating that, in reaching their decision, the directors breached one or
more  of  their  fiduciary  duties-good  faith,  loyalty  and due  care.  If the
presumption is not rebutted,  the business judgment rule attaches to protect the
directors  and  their  decisions,  and  their  business  judgments  will  not be
second-guessed.  Where, however, the presumption is rebutted, the directors bear
the burden of  demonstrating  the entire  fairness of the relevant  transaction.
Notwithstanding  the foregoing,  Delaware courts subject  directors'  conduct to
enhanced  scrutiny in respect of defensive actions taken in response to a threat
to corporate  control and approval of a transaction  resulting in a sale of such
control.

LIMITATIONS ON LIABILITY OF DIRECTORS

         Both the CBCA and the DGCL permit a  corporation  to limit the personal
liability of its  directors,  with  specified  exceptions.  Under the CBCA,  the
articles of  incorporation  may provide that a director  shall not be liable for


                                       75
<PAGE>

monetary damages for breach of fiduciary duty as a director,  provided, however,
that  such  limitation  of  liability  shall  not  apply  to any  breach  of the
director's  duty of loyalty to the corporation or to its  shareholders,  acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, the payment of unlawful  distributions  to shareholders as set
forth  in  Section  7-108-403  of the CBCA or any  transaction  from  which  the
director  directly or  indirectly  derived an  improper  personal  benefit.  The
Guaranty Charter  eliminates  director liability to the fullest extent permitted
by the CBCA.

         The DGCL  permits a  corporation  to include in its charter a provision
limiting or  eliminating  the liability of its directors to such  corporation or
its  shareholders  for monetary damages arising from a breach of fiduciary duty,
except  for:  (i) a breach  of the duty of  loyalty  to the  corporation  or its
shareholders,  (ii)  acts  or  omissions  not in good  faith  or  which  involve
intentional  misconduct or a knowing  violation of law, (iii) a declaration of a
dividend  or the  authorization  of the  repurchase  or  redemption  of stock in
violation of the DGCL or (iv) any transaction from which the director derived an
improper personal benefit.  The Orion Charter  eliminates  director liability to
the fullest extent permitted by the DGCL.

CALL OF SPECIAL MEETINGS

         Under the CBCA, a special meeting of shareholders  may be called by (i)
the board of directors or the persons  authorized by the bylaws or resolution of
the  board of  directors  to call such  meeting  or (ii) the  written  demand of
holders of 10% of the outstanding shares of a corporation entitled to be cast on
any issue proposed to be considered at the meeting. The Guaranty By-laws provide
that special meetings of Guaranty's  shareholders may be called by the President
or the  Secretary  upon the request  (which  shall state the purpose or purposes
therefor) of a majority of the Board of Directors or the holders of one-tenth or
more of the number of shares of outstanding  stock of Guaranty  entitled to vote
at the meeting.

         The DGCL permits  special  meetings of shareholders to be called by the
board of  directors  and such  other  persons,  including  shareholders,  as the
certificate of  incorporation  or bylaws may provide.  The DGCL does not require
that shareholders be given the right to call special meetings.

         Special meetings of shareholders of Orion may be called by the Chairman
of the Board or the Secretary at the written  request of a majority of the Board
of  Directors  or at the  written  request of the  holders by a majority  of the
entire capital stock of Orion issued and outstanding and entitled to vote.

ACTION BY SHAREHOLDERS WITHOUT A MEETING

         Under  the  CBCA,   unless  the  articles  of   incorporation  of  such
corporation provide otherwise, any action that may be taken by shareholders at a
meeting may be taken without a meeting with the unanimous written consent of all
shareholders  entitled to vote thereat. The Guaranty Charter does not modify the
CBCA.



                                       76
<PAGE>

         The DGCL  permits  the  shareholders  of a  corporation  to  consent in
writing to any action without a meeting, unless the certificate of incorporation
of such  corporation  provides  otherwise,  provided  such  consent is signed by
shareholders  having at least the minimum  number of votes required to authorize
such action at a meeting of  shareholders  at which all shares  entitled to vote
thereon were present and voted.  The Orion Charter  permits  shareholders to act
without a meeting.

SHAREHOLDER PROPOSALS

         Both Guaranty and Orion are subject to the rules and regulations of the
SEC regarding shareholder proposals. Guaranty's governing documents do not limit
the  ability of its  shareholders  to bring other  business  before a meeting of
shareholders.  However,  Orion's  By-Laws  require that there be furnished to it
written  notice with  respect to the  nomination  of a person for  election as a
director (other than a person nominated at the direction of the Board),  as well
as the  submission  of a  proposal  (other  than  a  proposal  submitted  at the
direction  of the Board),  at a meeting of  shareholders.  In order for any such
nomination  or  submission  to  be  proper,  the  notice  must  contain  certain
information concerning the nominating or proposing shareholder,  and the nominee
or the  proposal,  as the case may be, and must be  furnished to Orion not later
than by a date specified in accordance with the By-Laws.

AMENDMENT TO CHARTER DOCUMENT

         To  approve  a  charter  amendment  proposed  by the  Board,  the  CBCA
requires, unless the articles of incorporation, the By-Laws or any action by the
board of  directors  requires  a  greater  vote,  that the votes  cast  favoring
approval exceed the votes cast against such proposal or, in cases in which class
voting is  required,  such  approval by each class.  However,  for  corporations
incorporated prior to June 30, 1994,  Section  7-117-101(7) of the CBCA provides
that  unless  the  articles  of  incorporation  of such  corporation  contain  a
provision  establishing  the vote of the  shareholders  required  to  amend  the
articles of incorporation, such amendment shall be approved by each voting group
entitled to vote  separately  on the  amendment by  two-thirds  of all the votes
entitled  to be cast  on the  amendment  by  that  voting  group.  Guaranty  was
incorporated  prior to June 30, 1994,  and the Guaranty  Charter is silent as to
the required vote for approving an amendment to the Guaranty Charter.  Thus, the
two-thirds voting requirement is applicable to Guaranty.

         Under the DGCL  charter  amendments  may  generally  be approved by the
Board of Directors and the affirmative  vote of the holders of a majority of the
outstanding  shares of voting stock entitled to vote thereon.  The Orion Charter
provides  that it cannot be  amended  so as to alter the  powers  preference  or
special  rights of the Series B Junior  Participating  Preferred  Stock so as to
affect them adversely  without the affirmative vote of a majority of the holders
of such  stock  voting  separately  as a class.  If the  amendment  to the Orion
Charter did not affect the Series B Junior  Participating  Stock adversely,  the
holders  of a  majority  of the  outstanding  series  of voting  stock  would be
adequate to approve the amendment.



                                       77
<PAGE>

AMENDMENT AND REPEAL OF BY-LAWS

         With certain exceptions  relating to quorum or voting  requirements for
directors  or  shareholders,  the CBCA  provides  that  either  the Board or the
shareholders  may amend the By-Laws.  The Guaranty By-Laws provide that they may
be altered,  amended or repealed  and new bylaws may be adopted by a majority of
the Guaranty  Board  present at any meeting of the Board of Directors at which a
quorum is present.

         Under  the  DGCL,  holders  of a  majority  of the  voting  power  of a
corporation and, when provided in the Charter, the directors of the corporation,
have the power to adopt,  amend and repeal the  By-Laws  of a  corporation.  The
Orion Charter grants the Orion Board of Directors such power.

APPROVAL OF MERGERS AND ASSET SALES

         In  addition  to  Board  approval,  the  CBCA  requires  that  mergers,
consolidations,  dissolutions, and dispositions of all or substantially all of a
corporation's assets be approved,  by each voting group entitled to vote, voting
separately on such action, by a majority of all the votes entitled to be cast on
such proposal by that voting group unless the articles or the By-Laws  specify a
different  proportion.  The  Guaranty  Charter  does  not  specify  a  different
proportion.  However,  for  corporations  incorporated  prior to June 30,  1994,
Section   7-117-101(8)  of  the  CBCA  provides  that  unless  the  articles  of
incorporation of such corporation  contain a provision  establishing the vote of
the  shareholders  required  to  approve  a plan of  merger  or a plan of  share
exchange,  such plan of merger or plan of share  exchange  shall be  approved by
each voting group  entitled to vote  separately on the plan by two-thirds of all
the votes  entitled to be cast on the plan by that voting  group.  Guaranty  was
incorporated  prior to June 30, 1994,  and the Guaranty  Charter is silent as to
the  required  vote for  approving  a plan of merger or plan of share  exchange.
Thus, the two-thirds voting requirement is applicable to Guaranty.

         Under the DGCL,  unless  required  by  its-charter  (the Orion  Charter
contains no such  requirement),  no vote of the  shareholders  of a  constituent
corporation  surviving a merger is  necessary  to authorize a merger if: (i) the
agreement of merger does not amend the charter of such constituent  corporation;
(ii) each share of stock of such constituent  corporation  outstanding  prior to
such merger is to be an identical outstanding or treasury share of the surviving
corporation  after such  merger;  (iii)  either no shares of common stock of the
surviving corporation and no shares,  securities or obligations convertible into
such common stock are to be issued under such agreement of merger, or the number
of shares of common stock issued or  initially  issuable  does not exceed 20% of
the  number  thereof  outstanding  immediately  prior to such  merger;  and (iv)
certain other  conditions are satisfied.  In addition,  the DGCL provides that a
parent  corporation that is the record holder of at least 90% of the outstanding
shares of each class of stock of a  subsidiary  may merge such  subsidiary  into
such parent corporation  without the approval of such subsidiary's  shareholders
or  board  of  directors.  Whenever  the  approval  of  the  shareholders  of  a
corporation  is required for an agreement  of merger or  consolidation  or for a
sale,  lease  or  exchange  of all or  substantially  all  of its  assets,  such
agreement,  sale,  lease or exchange must be approved by the affirmative vote of


                                       78
<PAGE>

the holders of a majority of outstanding shares of such corporation  entitled to
vote thereon.

DISSENTERS' RIGHTS

         Pursuant to Section 7-113-102 of the CBCA,  dissenting  shareholders of
publicly  traded  companies are generally  not entitled to  dissenters'  rights.
However,  when the acquired  corporation  itself is a party to a merger or share
exchange transaction and the shareholders are receiving cash, other than cash in
lieu of fractional shares, shareholders are entitled to dissenters' rights.

         The DGCL  provides  for  appraisal  rights  only in the case of certain
mergers or consolidations  and not (unless the certificate of incorporation of a
corporation so provides,  which the Orion Charter does not) in the case of other
mergers,  a sale or  transfer  of all or  substantially  all of its assets or an
amendment to its charter.  Moreover,  the DGCL does not provide appraisal rights
in  connection  with a  merger  or  consolidation  (unless  the  certificate  of
incorporation  so provides,  which the Orion Charter does not) to the holders of
shares of a constituent corporation listed on a national securities exchange (or
designated as a national market system  security by the National  Association of
Securities  Dealers,  Inc.) or held of record by more than  2,000  shareholders,
unless the applicable agreement of merger or consolidation  requires the holders
of such shares to receive,  in exchange for such shares, any property other than
shares of stock of the  resulting or surviving  corporation,  shares of stock of
any other corporation listed on a national securities exchange (or designated as
described  above) or held of record by more than 2,000 holders,  cash in lieu of
fractional  shares or any  combination of the foregoing.  In addition,  the DGCL
denies appraisal  rights to the  shareholders of the surviving  corporation in a
merger  if  such  merger  did  not  require  for its  approval  the  vote of the
shareholders of such surviving corporation.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The CBCA provides that a corporation may indemnify,  against  liability
incurred in a proceeding,  a person made a party to the  proceeding  because the
person is or was a director if: (i) the person  conducted  himself or herself in
good faith and  reasonably  believed  (a) in the case of conduct in an  official
capacity with the corporation,  that his or her conduct was in the corporation's
best  interests  and (b) in all other  cases,  that his or her  conduct  was not
opposed  to the  corporation's  best  interests,  and  (ii)  in the  case of any
criminal  proceeding,  the person had no reasonable  cause to believe his or her
conduct was unlawful. A Colorado corporation may not indemnify a director (i) in
connection  with a proceeding by or in the right of the corporation in which the
director was adjudged liable to the corporation,  or (ii) in connection with any
other  proceeding  charging  that the  director  derived  an  improper  personal
benefit,  whether or not  involving  action in an  official  capacity,  in which
proceeding the director was adjudged  liable on the basis that he or she derived
an improper personal  benefit.  The Guaranty By-Laws provide that Guaranty shall
indemnify to the full extent  authorized or permitted by law, any person who was
or is a party or is threatened to be made a party to any threatened,  pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative  by reason of the fact that he is or was a director  or officer of


                                       79
<PAGE>

Guaranty or is or was serving at the  request of Guaranty in any  capacity  with
any other corporation, partnership, joint venture, trust or other enterprise.

         Section  145 of the DGCL  generally  provides  that a  corporation  may
indemnify  its  officers  and  directors  who were or are a party to any action,
suit, or proceeding  by reason of the fact that he was a director,  officer,  or
employee of the corporation by, among other things,  a majority vote of a quorum
consisting  of  directors  who  were  not  parties  to  such  action,  suit,  or
proceeding; provided that such officers and directors acted in good faith and in
a manner they reasonably  believed to be in or not opposed to the best interests
of the corporation.  The Orion Charter provides for  indemnification of officers
and directors to the fullest extent permitted by Delaware law. The Orion Charter
also  provides  that Orion may  indemnify  employees  and agents of Orion to the
fullest extent then permitted by Delaware law.

         Additionally, under the DGCL, advancement of expenses is permitted, but
a person receiving such advances must undertake to repay those expenses if it is
ultimately  determined  that he or she is not entitled to  indemnification.  The
Orion  By-Laws  provide  that Orion may pay  expenses  incurred  in  defending a
proceeding in advance of the final disposition of such proceeding upon the terms
and  conditions  authorized  by the Orion Board upon receipt of the  undertaking
described above.

ANTITAKEOVER PROVISIONS

         There   are  no   limitations   under   the  CBCA   with   respect   to
interested-shareholder  business combinations; nor are there any restrictions in
Guaranty  Charter  or  By-Laws  with  respect  to  such   interested-shareholder
transactions.  However,  Guaranty has adopted the Shareholder Rights Plan, which
may have certain  antitakeover  effects.  See "The Offer - Certain Conditions of
the Offer."

         Section 203 of the DGCL  prohibits  a  corporation  from  engaging in a
"business combination" (as hereinafter defined) with an "interested shareholder"
(defined generally to mean a person who, together with his affiliates,  owns, or
if the person is an affiliate of the  corporation  did own within the last three
years,  15% or more of the  outstanding  voting stock of the corporation ) for a
period of three  years  after the date of the  transaction  in which the  person
became an interested  shareholder,  unless (i) prior to the date of the business
combination  of the  transaction in which the  shareholder  became an interested
shareholder,  the board of  directors  of the  corporation  approved  either the
business  combination  or the  transaction  which  resulted  in the  shareholder
becoming  an  interested   shareholder;   (ii)  as  a  result  of  the  business
combination,  the interested  shareholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced or (iii) on
or  subsequent to the date of the business  combination,  the board of directors
and the holders of at least 66 2/3 of the outstanding  voting stock not owned by
the interested shareholder approve the business combination.  The DGCL defines a
"business  combination"  generally  as: (i) a merger or  consolidation  with the
interested   shareholder  or  with  an  other   corporation  if  the  merger  or
consolidation  is caused  by the  interested  shareholder,  (ii) a sale or other


                                       80
<PAGE>

disposition  to or with an  interested  shareholder  of assets with an aggregate
value of all assets of the  corporation or the aggregate  market value of all of
the outstanding  stock of the corporation;  (iii) with certain  exceptions,  any
transaction  resulting  in the  issuance or transfer by the  corporation  or any
majority- owned subsidiary of any stock of the corporation or such subsidiary to
the interested shareholder;  (iv) any transaction involving the corporation or a
majority-owned  subsidiary  that has the effect of increasing the  proportionate
share  of the  stock of the  corporation  or any  such  subsidiary  owned by the
interested shareholder;  or (v) any receipt by the interested shareholder of the
benefit of any loans or other financial  benefits provided by the corporation or
any majority-owned subsidiary.

RIGHTS OF INSPECTION

         Under  both the CBCA  and the  DGCL,  every  shareholder,  upon  proper
written  demand  stating  the  purpose  thereof  and  subject to  certain  other
restrictions,  may  inspect  the  corporate  books and  records  as long as such
inspection is for a proper purpose and during normal business hours.  Under both
statutes,  a "proper purpose" is any purpose  reasonably related to the interest
of the inspecting person as a shareholder.

LIQUIDATION RIGHTS

         The rights of the holders of Guaranty Common Stock upon the liquidation
or  dissolution of Guaranty are  substantially  the same as the holders of Orion
Common Stock upon the liquidation or dissolution of Orion.  See  "Description of
Orion Common Stock -- General."

                                  LEGAL MATTERS

         The  validity of the Orion  Common Stock to be issued in the Offer will
be passed upon for Orion by Donovan Leisure Newton & Irvine.

                                     EXPERTS

         The  consolidated   financial  statements  and  the  related  financial
statement  schedules  incorporated  in this Prospectus by reference from Orion's
Annual  Report  on Form  10-K for the year  ended  December  31,  1996 have been
audited  by  Deloitte & Touche  LLP,  independent  auditors,  as stated in their
report, which is incorporated herein by reference, and have been so incorporated
in reliance  upon the report of such firm given upon their  authority as experts
in accounting and auditing.

         With respect to the unaudited  interim  financial  information of Orion
which is  incorporated  herein by reference,  Deloitte & Touche LLP have applied
limited  procedures in accordance  with  professional  standards for a review of
such  information.  However,  as stated in their  reports  included  in  Orion's
Quarterly  Reports on Form 10-Q and incorporated by reference  herein,  they did
not  audit  and  they  do not  express  an  opinion  on that  interim  financial
information.  Accordingly,  the  degree of  reliance  on their  reports  on such
information  should be restricted  in light of the limited  nature of the review
procedures  applied.  Deloitte  & Touche LLP are not  subject  to the  liability
provisions of Section 11 of the  Securities Act of 1933 for their reports on the
unaudited interim financial  information because those reports are not "reports"

or a "part" of the registration statement prepared or certified by an accountant
within the meaning of Sections 7 and 11 of the Securities Act of 1933.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Orion is a Delaware  corporation.  Reference  is made to Section 145 of
the  Delaware  General  Corporation  Law as to  indemnification  by Orion of its
officers  and  directors.  The  general  effect  of  such  law is to  empower  a
corporation  to  indemnify  any of its officers and  directors  against  certain
expenses  (including  attorneys'  fees),  judgments,  fines and amounts  paid in
settlement  actually and reasonably  incurred by the person to be indemnified in
connection with certain actions,  suits or proceedings  (threatened,  pending or
completed) if the person to be  indemnified  acted in good faith and in a manner
he  reasonably  believed to be in, or not opposed to, the best  interests of the
corporation  and,  with respect to any  criminal  action or  proceeding,  had no
reasonable cause to believe his conduct was unlawful.

         Article  VII of  Orion's  Restated  Certificate  of  Incorporation,  as
amended  and  Article  IX of  Orion's  By-Laws,  as  amended,  provide  for  the
indemnification  of  Orion's  officers  and  directors  in  accordance  with the
Delaware  General  Corporation  Law, and  include,  as permitted by the Delaware
General Corporation Law, certain limitations on the potential personal liability
of members of Orion's  Board of Directors  for  monetary  damages as a result of
actions taken in their capacity as Board members.

         Orion has entered  into  indemnification  agreements  (approved  by its
shareholders)  with each of its directors and senior officers which, among other
things,  contractually  confirm the indemnity  provided  under Orion's  Restated
Certificate of Incorporation,  its By-Laws and the Delaware General  Corporation
Law.

         The directors  and officers of Orion are covered by insurance  policies
indemnifying them against certain  liabilities  arising under the Securities Act
which might be incurred by them in such capacities.

         The Trust Agreement limits the liability to the Trust and certain other
persons,  and provides for  indemnification  by the Trust or Orion, of Trustees,
their officers, directors and employees and certain other persons.

ITEM 22.  UNDERTAKINGS.

         The  undersigned  registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities  Act of 1933, as amended,  each
filing of Orion's  annual  report  pursuant to section 13(a) or section 15(d) of
the Securities  Exchange Act of 1934 (and, where  applicable,  each filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of 1934),  that is  incorporated  by reference in this
Registration  Statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (2) That prior to any public  reoffering of the  securities  registered
hereunder  through  use of a  prospectus  which  is a part of this  registration
statement,  by any person or party who is deemed to be an underwriter within the
meaning  of  Rule  145(c),  the  registrant   undertakes  that  such  reoffering
prospectus will contain the  information  called for by Form S-4 with respect to
reofferings  by  persons  who may be deemed  underwriters,  in  addition  to the
information called for by the other items of Form S-4.

         (3) That every  prospectus  (i) that is filed pursuant to paragraph (2)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Act and is used in  connection  with an  offering of  securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective,  and that, for
purposes of determining  any liability  under the  Securities Act of 1933,  each
such post-effective amendment shall be deemed to be a new registration statement

                                       II-3
<PAGE>

relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

         The undersigned registrant hereby undertakes to respond to requests for
information  that is incorporated  by reference into the Prospectus  pursuant to
Items 4, 10(b), 11 or 13 of this Form S-4, within one business day of receipt of
such request,  and to send the  incorporated  documents by  first-class  mail or
other equally  prompt means.  This includes  information  contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

         The undersigned  registrant  hereby  undertakes to supply by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the registration statement when it became effective.

undersigned  registrant certifies that it has reasonable grounds to believe that
it meets all of the requirements for filing on Form S-4 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned,  thereunto
