                              COLUMBUS ENERGY CORP.
            400,000 Shares of Series A 7% Convertible Preferred Stock

     Columbus   Energy  Corp.   ("Columbus"   or  the  "Company")  has  filed  a
Registration  Statement  covering  400,000 shares of its authorized  Series A 7%
Convertible   Preferred  Stock  (the  "Preferred  Stock").   The  offering  (the
"Offering") is being made by the distribution of subscription  rights ("Rights")
to   purchase   Preferred   Stock  to   Columbus   shareholders   of  record  on
______________,  19__.  One Right  will be issued  for each  share of  Columbus'
common stock,  no par value ("Common  Stock") held of record.  Eight Rights plus
$25 in cash (the  "Offering  Price")  will be required to purchase  one share of
Preferred Stock, or, in the alternative, shareholders who purchase round lots of
100 shares of Preferred Stock may substitute in lieu of cash up to 100 shares of
Common  Stock and  receive a credit of $12.50 for each share of Common  Stock so
relinquished (up to a maximum credit of $1,250) toward the $2,500 purchase price
per round lot of Preferred Stock. Those holders of Rights who fully subscribe to
their primary  subscription  will be allowed to oversubscribe in accordance with
an oversubscription privilege. See "Subscription Offer."

     The Rights  expire at 4:00 P.M.  Eastern  Standard  Time on  _____________,
19____,   subject  to   extension   by   Columbus  to  a  date  not  later  than
_______________, 19__. See "Subscription Expiration Date" and "Purchase and Sale
of Rights."  There are no minimum  amounts which must be subscribed  for in this
Offering.

     The Offering  Price of the Preferred  Stock was set by Columbus  based upon
its $25 per share redemption value, the dividend rate of 7%, its  convertibility
into shares of Common Stock,  and the current  market price of the Common Stock.
On August 31,  1996,  the book value of Columbus was  $14,690,633,  or $4.76 per
share. The Offering Price may or may not have any correlation to the fair market
value of the Company or the trading  price for the Preferred  Stock  immediately
after the Offering. See "Risk Factors - Establishment of Offering Price."

     The Rights are transferable and are expected to trade on the American Stock
Exchange.  The  Preferred  Stock is  expected  to trade  on the  American  Stock
Exchange if the  requirements of the exchange are met; in the  alternative,  the
Preferred Stock will trade on the  over-the-counter  market. See "Risk Factors -
No Assurance of a Public Market."

     All of the proceeds  from the sale of the  Preferred  Stock will be paid to
Columbus. The expenses of the Offering are estimated to be $_____________.

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

Summary of the Rights Offering

General             The Offering is being made by means of the  distribution  of
                    subscription   rights   ("Rights")  as  a  dividend  to  the
                    shareholders of Columbus. Eight Rights plus $25 in cash (the
                    "Offering Price"), entitles the holder to purchase one share
                    of Preferred Stock, or, in the alternative, shareholders who
                    purchase  round  lots of 100 shares of  Preferred  Stock may

                    subscription.  There are no  minimum  amounts  which must be

Purpose of the Rights
   Offering         To reduce  bank  debt,  to add to  working  capital,  and to
                    create a  trading  market  for the  Preferred  Stock so that
                    additional  authorized  shares of Preferred  Stock not being
                    issued as a part of the Offering may be issued in connection
                    with possible  acquisitions or to raise  additional  working
                    capital.

Establishment of Offering
   Price            The  Offering  Price  of  the  Preferred  Stock  was  set by
                    Columbus based upon its $25 per share redemption  value, the
                    dividend  rate of 7%,  its  convertibility  into  shares  of
                    Common  Stock,  and the current  market  price of the Common
                    Stock.  On August 31,  1996,  the book value of Columbus was
                    $14,690,633,  or $4.76 per share.  The Offering Price may or
                    may not have any correlation to the fair market value of the
                    Company  or  the  trading  price  for  the  Preferred  Stock
                    immediately   after  the  Offering.   See  "Risk  Factors  -
                    Establishment of Offering Price."

Terms of Series A 7% Convertible 
   Preferred Stock  Each share of  Preferred  Stock  entitles  its holder to one
                    vote  on  all  matters  for  which  a  shareholder  vote  is
                    required.  No cumulative voting is permitted in the election
                    of  directors.   Dividends  will  accrue  on  the  Series  A
                    Preferred  Stock at the rate of 7% per annum of the $25 face
                    value per share.  Accrued  dividends  will be payable  semi-
                    annually when, as and if declared by the Board of Directors,
                    or at such other times as the Board of Directors determines.
                    In  addition,  the  Company  may pay  dividends  only to the
                    extent  that it has  legally  available  funds to do so. The
                    Board  expects  that it will  have  funds  available  to pay
                    dividends   on  the  Series  A   Preferred   Stock  for  the
                    foreseeable  future.  Dividends  not paid on the  applicable
                    dividend payment date will cumulate.  Each share of Series A
                    Preferred  Stock is  convertible  into  Common  Stock at the
                    option of the holder commencing 60 days after the issue date
                    of the Series A Preferred Stock, at the rate of _____ shares
                    of Common  Stock for each share of Series A Preferred  Stock
                    converted. The Series A Preferred Stock is redeemable at the
                    option of the  Company  at a premium  of 110% of face  value
                    through  November  30,  1999,  at 105% of  face  value  from
                    December 1, 1999  through  November  30,  2005,  and at face
                    value  thereafter.  The  Company is  required  to redeem the
                    Series A Preferred  Stock at the  foregoing  prices upon the
                    occurrence of certain  specified events deemed to constitute
                    a change of control of the Company. Upon any dissolution and
                    winding up of the Company, the Series A Preferred Stock will
                    be entitled  to a  liquidation  preference  of $25 per share
                    plus accrued and unpaid dividends, if any. Holders of shares
                    of Series A  Preferred  Stock will not be  entitled to share
                    with the Common Stock in any other or further  distributions
                    in a liquidation of the Company,  if any such  distributions
                    were available. See "Description of Capital Stock."

Use of Proceeds     Columbus  expects  to use the net  cash  proceeds  from  the
                    Offering  first to  reduce  bank  debt and then to  increase
                    working  capital  required for future capital  expenditures.
                    Expected capital  expenditures include development of proved
                    undeveloped  reserves,  existing  drilling projects (such as
                    the  Company's  12.5%  participation  in  the  drilling  and
                    completion  of several  dual lateral oil wells in the Austin
                    Chalk  formation  on  its  leaseholds  in  Louisiana),   and
                    exploration costs. See "Management's Discussion and Analysis
                    of  Financial  Condition  and  Results of  Operations-Recent
                    Activities."

Trading Market      There is no presently  established  market for the Preferred
                    Stock being  offered  pursuant to the  Offering.  Final AMEX
                    listing   approval  is  subject  to  satisfaction  of  share
                    distribution  requirements  (as  to  which  there  can be no
                    assurance),  which  includes the  requirement  that at least
                    100,000  shares be owned by  non-affiliates.  It is expected
                    that the Preferred Stock will trade on the  over-the-counter
                    market if the AMEX  distribution  requirements  are not met.

                                  RISK FACTORS

     The securities  offered by this  Prospectus  involve a high degree of risk.
Each holder of Rights should  carefully  read the entire  Prospectus  but should
give special consideration to the risk factors described below.

     This Prospectus contains  forward-looking  statements within the meaning of
Section 27A of the Securities Act of 1933. Such  forward-looking  statements may
be found in this Section and under  "Prospectus  Summary," "Use of Proceeds" and
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations."  Actual  events or  results  could  differ  materially  from  those
including, without limitation, the risk factors set forth below and elsewhere in
this  Prospectus.  In  addition  to the  other  information  contained  in  this
Prospectus,  the risk factors  below should be  considered  when  evaluating  an
investment in the shares of Preferred Stock offered.

Fluctuation in Prices of Oil and Natural Gas

     The  Company's  revenues and  earnings  are  dependent to a large degree on
prevailing  prices  for oil and  natural  gas and the  replacement  of  produced
reserves which are economic at those prices.  For the past twenty years, oil and
natural gas prices have been  volatile  and are expected to continue to be so in
the future.  Currently, more than 55% of the Company's revenues are derived from
the  production  and sale of natural gas, which in turn causes cash flow and net
earnings to be more  affected by the  volatility  of natural gas prices than oil
prices.  See  "Management's  Discussion and Analysis of Financial  Condition and
Results of Operations."

Drilling Risks

     The  Company's  oil and  natural gas  operations  are subject to all of the
business risks typically associated with drilling for oil and natural gas. These
risks often include the expenditure of large amounts of money for identification
and acquisition of prospective  leasehold acreage with no assurance that oil and
natural gas will be found in commercial quantities when a well is drilled.

Operating Hazards and Uninsured Risks

     The oil and gas business involves numerous operating risks, including fire,
explosion, pipe failure, casing collapse,  abnormally pressured formations,  and
environmental  hazards such as oil spills,  natural gas leaks, and discharges of
toxic gases.  The occurrence of any of these events with respect to any property
operated  or owned (in whole or in part) by the  Company  could  have a material
adverse  effect  on the  Company's  financial  condition.  The  Company  and the
operators of its  properties  maintain  insurance in accordance  with  customary
industry  practices and in amounts that  management  believes to be  reasonable.
However,  insurance  coverage  is not always  economically  feasible  and cannot
always be obtained,  without  significant  exclusions,  in amounts sufficient to
cover all types of operational risks. The occurrence of a significant event that
is not fully  insured  could have a  material  adverse  effect on the  Company's
financial condition.

                                        8
<PAGE>

Competition

     The oil and  natural  gas  industry  is  highly  competitive.  The  Company
competes with others for property  acquisitions and for opportunities jointly to
explore or to develop and produce oil and natural gas. The Company's competitors
include  major  companies  and  other  independent  energy  concerns,  including
individual  operators.  Many of these  competitors  have  substantially  greater
financial and other resources than the Company.

Potential Adverse Impact of Environmental and Other Governmental Regulation

     Oil and  natural  gas  operations  are  subject to various  regulation  and
legislation of the federal and state governments,  including environmental laws.
To date,  the Company has not had to expend  significant  resources  in order to
satisfy  environmental  laws  and  regulations  presently  in  effect.  However,
compliance  costs under any new laws and regulations that might be enacted could
become  material.  Additional  matters that are, or have been from time to time,
subject to governmental  regulation include land tenure,  royalties,  production
rates, spacing,  completion procedures,  water injection,  unitization,  and the
maximum price at which products could be sold.

Potential Adverse Effects of Weather on Results of Operations

     The results of operations of Columbus can be adversely  affected by weather
conditions,  which  can  also  bring  about  lower  energy  usage  or  increased
availability of alternative energy sources, which in turn reduces the demand for
and prices for natural gas and oil produced by the Company.

Uncertainty of Estimates of Oil and Gas Reserves and Future Net Revenues

     The  Company's  recent  annual  report  on Form 10-K for  fiscal  year 1995
contained  estimates  of the  Company's  oil and  natural gas  reserves  and the
discounted  future net revenues to be realized from those reserves,  as prepared
by independent petroleum engineers,  for fiscal years 1995, 1994 and 1993. There
are numerous  uncertainties  inherent in estimating quantities of proved oil and
natural gas reserves, including many factors beyond the control the Company. The
estimates  in Form 10-K utilize  assumptions  that the  Securities  and Exchange
Commission ("SEC") requires all public companies, including Columbus, to follow,
such as using  constant oil and gas prices with no escalation  allowed except as
specifically  provided for by contract.  Such estimates are inherently imprecise
indications of future net revenues.  Actual future production,  revenues, taxes,
operating expenses,  development  expenditures and quantities of recoverable oil
and natural gas  reserves  might vary  substantially  from those  estimates  and
assumptions.  Any  significant  variance in such  assumptions  could  materially
affect the estimated quantity and value of reserves set forth in such estimates.
In addition,  the  Company's  reserves  might be subject to revision  based upon
future  production  results,  future  exploitation and development  successes or
failures, actual prices received and other unpredictable factors.

No Assurance of a Public Market

     There  is  presently  no  trading  market  for  the  Preferred  Stock.  The
establishment  of a liquid  trading  market for the Preferred  Stock will depend
upon a sufficient  number of shares being sold in the Offering to a sufficiently
large  number of holders  who are not  affiliates,  as to which  there can be no
assurance.  There also is no  assurance  as to the price at which any  purchaser
would be able to resell Preferred Stock following the Offering.

     The Company has requested  approval for listing the Preferred  Stock on the
AMEX  but can  give no  assurance  that  the  Preferred  Stock  will  meet  AMEX
distribution requirements. The principal requirement applicable to the Preferred
Stock (in light of the fact that the Common Stock already is listed on the AMEX)
is that  100,000  shares must be owned by  non-affiliates.  (Other AMEX  listing
requirements  include that the Preferred  Stock have an aggregate  public market
value of  $2,000,000  and a trading  price of at least $10 per share,  which the
Company expects will be satisfied.)

     The  market  price  for the  Preferred  Stock  will be  influenced  by many
factors,  including  interest  rates,  the  market  price of the  Common  Stock,
investor  perceptions  of the value of the assets of the Company,  the Company's
ability to pay dividends on the Preferred Stock, and general economic and market
conditions.

Establishment of Offering Price and Conversion Rate

     In  determining  the  Offering  Price,  Columbus  took  into  consideration
primarily the liquidation preference assigned to the shares. To a lesser degree,
Columbus  considered the 7% dividend rate and the fact that the conversion price
into shares of Common Stock would exceed the market price of those shares on the
offering date by 25% or more. There is no assurance that the Offering Price will
bear any  correlation to the fair market value of the Preferred  Stock or to the
trading price of the Preferred Stock immediately after the Offering. The rate at
which the  Preferred  Stock may be converted  into Common  Stock was  determined
based on the  ratio of the Face  Value  of the  Preferred  Stock to the  current
market value of the Common Stock.

Control by Affiliates

     Harry  A.  Trueblood,  Jr.,  who  currently  has  beneficial  ownership  of
approximately  25% of the  Common  Stock,  intends  to  subscribe  fully  in the
Offering (and may oversubscribe).  Other directors and officers of Columbus have
stated their intention to subscribe at varying levels.

Potential Dilution of Earnings Due to Offering

     The Offering may have a short-term  dilutive  effect on the  calculation of
earnings per share of Common  Stock,  which could have an adverse  impact on the
market  price  of the  Common  Stock  and  the  Preferred  Stock.  If all of the
Preferred Stock offered is sold, the Company will have almost $10 million of net
proceeds  from the Offering.  Dividends on the Preferred  Stock will accrue from
the issue date at the rate of 7%. Some of the proceeds from the Offering will be
used to reduce bank debt (and  therefore  will reduce  interest  charges),  some
shares  of Common  Stock  may be  redeemed  as a part of the  Offering,  and the
Company may have interest income from the short-term investment of proceeds from
the Offering. However, the overall impact of the issuance of the Preferred Stock
initially  may be to reduce  earnings per share of Common  Stock.  This dilutive
effect  will be reduced or  eliminated  to the extent  that  Columbus is able to
invest the proceeds of the  Offering  (as well as other  sources of capital) and
obtain a return that exceeds the 7% dividend rate on the Preferred  Stock (as to
which there can be no assurance).

Uncertainty Regarding Future Dividend Policies

     Historically,  Columbus has paid no cash dividends on its Common Stock. The
future  payments of  Preferred  Stock  dividends  will be dependent on Columbus'
results of operations, financial condition, needs for working capital, and other
factors,  and  may be  subject  to  restrictions,  if  any,  contained  in  debt
instruments  in effect from time to time. In addition,  the payment of Dividends
on the  Preferred  Stock is subject to the  discretion of the Board of Directors
and to  limitations  imposed by Colorado  corporate  law.  See  "Description  of
Capital Stock-Series A 7% Preferred Stock."


                                   THE COMPANY

     Columbus  Energy  Corp.  ("Columbus")  was  incorporated  under the laws of
Colorado  on October 7, 1982.  Columbus  engages in the  production  and sale of
crude  oil,  condensate  and  natural  gas,  as  well  as  the  acquisition  and
development of leaseholds  and other  interests in oil and gas  properties,  and
also acts as  manager  and  operator  of oil and gas  properties  for itself and
others.  It also  engages  in the  business  of  compression,  transmission  and
marketing  of natural gas  through its  wholly-owned  subsidiary,  Columbus  Gas
Services,  Inc.  ("CGSI"),  a  Delaware  corporation.  The  term  "Company"  and
"Columbus" as used in this Prospectus include Columbus'  subsidiaries unless the
context otherwise indicates.

     The Company  currently  has 33  employees,  including  a  technical  staff,
comprised of four petroleum engineers and one landman.  The administrative staff
provides  support  required  for  accounting  and  data  processing,   including
disbursement of monthly oil and gas revenues,  joint interest billing functions,
and accounts payable.

     On  February  24,  1995,  Columbus  completed  a  rights  offering  to  its
shareholders  to  purchase  one  share  of  common  stock  of  its  wholly-owned
subsidiary, CEC Resources Ltd., an Alberta, Canada corporation, at U.S. $3.25 in
cash plus two subscription  rights.  One right was distributed as a dividend for
each share of Common  Stock held of record on January 27,  1995.  All  1,500,000
shares of Resources' common stock were sold in the rights offering,  yielding an
aggregate of $4,875,000 to Columbus.

     The Rights expire at 4:00 P.M.,  Eastern  Standard Time, on  _____________,
1997,  unless  extended by  Columbus to a date not later than  ________________,
1997 (such date or  extended  date,  as the case may be, is  referred  to as the
"Expiration Date"). See "Purchase and Sale of Rights" below.

Subscription Privileges

     Holders of Rights may purchase one share of Preferred  Stock for each eight
Rights plus the payment of $25 in cash.  In the  alternative,  shareholders  who
purchase  round lots of 100 shares of Preferred  Stock may substitute in lieu of
cash up to 100  shares of Common  Stock and  receive a credit of $12.50 for each
share of Common Stock so relinquished  (up to a maximum credit of $1,250) toward
the $2,500 purchase price of a round lot.

     Odd lot holders of Common  Stock (less than 100 shares) who wish to acquire
one round lot of 100 shares of Preferred Stock may tender all of their shares of
Common Stock as partial  payment  based on a $12.50 per share credit  toward the
$2,500 total  purchase price along with the required  balance in cash.  Such odd
lot  holders  must  instruct  the  Subscription   Agent  to  acquire  sufficient
Additional Rights (not to exceed a total of 799 Rights) for their account which,
when added to their tendered  Rights,  will equal the 800 Rights  required.  Any
holder  of Rights  who has fully  exercised  the  basic  subscription  privilege
associated  with the ownership of the holder's  Rights (the "Basic  Subscription
Privilege") may also subscribe at the Offering Price for any number of shares of
Preferred  Stock  not  subscribed  for  by  other  Columbus   shareholders  (the
"Oversubscription  Privilege").  No Rights are  required to  participate  in the
Oversubscription Privilege.

     The Company is unable to estimate the number of shares of  Preferred  Stock
that will be available  for the  Oversubscription  Privilege,  because it cannot
predict  the  level of  subscription  under the  Basic  Subscription  Privilege.
However,  as of December 31, 1996,  there were 3,163,868  shares of Common Stock
outstanding;  if all  3,163,868  Rights  distributed  were utilized in the Basic
Subscription Privilege,  there would still would be a modest number of shares of
Preferred Stock available for the Oversubscription Privilege.

                                       14
<PAGE>

     The only  shares of  Preferred  Stock  available  for the  Oversubscription
Privilege  are those  shares  not  required  to satisfy  the Basic  Subscription
Privilege  (the  "Additional  Preferred  Stock").  If the  number  of  shares of
Preferred  Stock so available  is not  sufficient  to satisfy all  subscriptions
received  pursuant to the  Oversubscription  Privilege,  the  available  pool of
unsubscribed  shares will be allotted pro rata,  subject to the  elimination  of
fractional  shares,  among  those  holders  who  exercise  the  Oversubscription
Privilege, in proportion to the number of shares of Preferred Stock purchased by
them pursuant to the Basic Subscription  Privilege.  An oversubscription must be
accompanied  by a cash deposit equal to 20% of the total  purchase  price of the
shares of Preferred Stock to which the holder proposes to oversubscribe.  To the
extent that an oversubscription  is accepted,  the balance of the Offering Price
must be paid in cash  (and/or  Common  Stock) upon notice from the  Subscription
Agent as to such  amount  due.  No shares of Common  Stock  should be  initially
tendered toward the 20% partial payment deposit for  oversubscribed  shares. See
"Method  of  Subscription."  The  Subscription  Agent will  promptly  refund the
initial cash deposit to those holders who utilize the Oversubscription Privilege
to the extent that the shares of  Additional  Preferred  Stock are not available
for  allotment to the holders.  No interest  will be paid on deposits  which are
refunded.

     Rights  may be  bought  and  sold  through  usual  investment  and  trading
channels.  It is expected  that the Rights will be traded on the AMEX and on the
over-the-counter  market,  but that trading on the AMEX will be  discontinued at
the close of  business  one day prior to the  Expiration  Date,  after which the
Rights  may  continue  to be traded  on the  over-the-counter  market  until the
Expiration Date.

     For the convenience of Certificate holders, the Subscription Agent will, on
request and without  charge,  handle orders to buy (not  exceeding 799 Rights on
any one  subscription)  or sell  Rights  (not  exceeding  799  Rights on any one
subscription) for the account of any Certificate holder, in order to assist such
holder in rounding out his  subscription  for 100 shares of  Preferred  Stock or
disposing of fewer than 799 Rights.  Columbus will pay the Subscription  Agent's
service charge on such purchases and sales. The Subscription Agent may match the
orders of buyers and sellers of Rights to the extent both are available. Charges
or credits upon purchase and sale of Rights,  including matched orders, each day
will equate to the average price paid or received by the  Subscription  Agent in
the open market for the Rights  purchased  or sold.  Holders will receive a bill
for the costs of Rights purchased or a check for the proceeds of Rights sold.

Method of Subscription

     The Rights may be exercised by completing and signing the subscription form
on the  reverse of the Rights  Certificate  and mailing it or  delivering  it to
Harris Trust Company of New York (the "Subscription Agent").  Subscriptions must
be  accompanied  with  payment  in full in cash  for the  number  of  shares  of
Preferred Stock subscribed for pursuant to the Basic  Subscription  Privilege or
cash plus the  tendered  shares of Common  Stock  proposed to be used as partial
payment  for the round  lots of  Preferred  Stock.  Not more than 100  shares of
Common Stock may be used toward the purchase of each round lot  subscribed.  For
those  wishing  to  oversubscribe,  a cash  deposit  equal  to 20% of the  total
purchase  price of the number of shares of Preferred  Stock being  subscribed to
pursuant  to  the   Oversubscription   Privilege   should  accompany  the  Basic
Subscription Rights Certificate.  The balance, if any, of the purchase price for
oversubscribed shares must be paid for in cash, or in cash plus shares of Common
Stock  tendered  (not to exceed 100 per round lot) toward the purchase  price at
the same  $12.50  per  share  credit  permitted  under  the  Basic  Subscription
Privilege,  and must be paid within five  business days after notice is given by
the Subscription Agent. All payments must be made by check, bank draft or postal
express  money  order,  payable  in United  States  dollars  to the order of the
Subscription Agent.

Late Delivery of Certificates

     Subscriptions will be accepted without delivery of the Rights  Certificates
if, prior to the Expiration  Date, the  Subscription  Agent receives  payment as
specified  above in respect  to the total  number of shares of  Preferred  Stock
subscribed  for upon the exercise of Rights  (including the 20% cash deposit for
Preferred  Stock  proposed  to be  purchased  pursuant  to the  Oversubscription
Privilege),  together with a letter or telegram from a bank or trust company,  a
member of the New York Stock Exchange,  or another national securities exchange,
stating the number of Rights  represented by the subscriber's  Certificate,  the
number of shares of Preferred Stock  subscribed for, and the name of subscriber,
and  guaranteeing  that such  Certificate  will be received at the office of the
Subscription  Agent no later than 4:00 P.M.  Eastern  Standard time,  within two
business days  thereafter.  Any such  subscription  will be accepted  subject to
withholding  delivery of certificates for Preferred Stock until the Subscription
Agent's receipt of the applicable duly exercised Certificate or Certificates.

Delivery of Shares

     The  Preferred  Stock  subscribed  for  pursuant to the Basic  Subscription
Privilege will be mailed as soon as practicable by the Subscription  Agent. If a
Certificate   holder   subscribes   for   Preferred   Stock   pursuant   to  the
Oversubscription  Privilege,  shares of Preferred  Stock issued  pursuant to the
Basic Subscription  Privilege and the Oversubscription  Privilege will be mailed
as soon as  practical  after the  Subscription  Agent has  determined  the total
number of shares of Additional Preferred Stock are allocable to the holder. If a
holder who has subscribed for Preferred  Stock pursuant to the  Oversubscription
Privilege  wishes  to  receive  the  Preferred  Stock  issuable  under the Basic
Subscription  Privilege  prior to the  determination  of the number of shares to
which the holder is entitled under the  Oversubscription  Privilege,  the holder
may obtain such shares by making a written request to the Subscription Agent.

     All expenses in connection with the  distribution of the Shares,  including
fees and expenses of the Company's  Subscription Agent, counsel and accountants,
filing fees and printing expenses, will be borne by the Company.


               FEDERAL INCOME TAX MATTERS RELATING TO THE OFFERING

     In the opinion of Coopers & Lybrand L. L. P., tax advisors to Columbus, the
Federal income tax consequences of this Offering under the Internal Revenue Code
of 1986 will be as described below.

Receipt of the Rights

     Generally, a corporation may make a distribution of its stock, or rights to
acquire its stock,  to its  shareholders in respect of the  corporation's  stock
without the shareholder including the distribution in gross income. However, the
distribution  of convertible  preferred  stock, or rights to acquire such stock,
will be  deemed  taxable  to the  recipient  unless it is  established  that the
distribution  does  not  result  in  a  disproportionate  distribution.  Such  a
distribution  is defined as one which results in the receipt of property by some
shareholders  and an  increase  in the  proportionate  interest in the assets or
profits of the corporation by other shareholders.

     Treasury  Regulations  further provide that the distribution of convertible
preferred  stock,  or rights to acquire  such  stock,  will  likely  result in a
disproportionate  distribution when both of the following  conditions exist: (a)
the conversion  right must be exercised within a relatively short period of time
after the  distribution  of the stock;  and (b)  considering  the dividend rate,
redemption   provisions,   marketability  of  the  convertible  stock,  and  the
conversion  price, it may be anticipated  that some  shareholders  will exercise
their  conversion  rights  and some will  not.  If the  conversion  right may be
exercised over a period of years and the dividend rate is consistent with market
conditions at the time of the distribution of the stock or the rights to acquire
the stock, it is unlikely a disproportionate distribution will occur.

     Distribution of the Rights will be proportionate to the existing  ownership
of Common Stock,  and the Preferred  Stock remains  convertible at the option of
the holder for an indefinite period. Based on the foregoing, the distribution of
the Rights  should not be  considered  disproportionate  for federal  income tax
purposes and Columbus  shareholders  need not include  amounts in respect of the
distribution in gross income.

                                       17
<PAGE>

     Because the  distribution of the Rights to existing  Columbus  shareholders
will not be included in gross income,  the Rights,  and ultimately the Preferred
Stock,  may be  considered to be Section 306 Stock.  Should a shareholder  later
dispose of the Section 306 Stock, or the rights to acquire such stock, in a sale
or exchange,  all or a portion of the amount realized on the disposition will be
treated as ordinary gain.  This treatment is limited to the fair market value of
the  underlying  Rights at the date of  distribution.  The  amount  realized  on
disposition  in excess of the ordinary  income plus the  adjusted  basis will be
treated as capital gain as long as the Right or the Preferred Stock is a capital
asset to the holder.  Should a shareholder sell all the  shareholder's  Columbus
capital  stock  including the Rights in a single  transaction,  then Section 306
would not apply.

     If it is  established  that Columbus  does not have current or  accumulated
earnings or profits for the taxable year of the distribution, neither the Rights
nor  the  Preferred  Stock  will  be  treated  as  Section  306  Stock.  Such  a
determination  can not be made until the end of the fiscal year on November  30,
1997.  Preferred Stock acquired  through the exercise of Rights purchased on the
open  market by  existing  shareholders  or  investors  will not be  subject  to
classification as Section 306 Stock.

     In general,  the tax basis of the Rights received by Columbus  shareholders
will be derived  from an  allocation  of the tax basis of Common  Stock  already
held.  Such  allocation  is in  proportion to the relative fair market values of
that  stock  and that of the  Rights  on the date of  distribution.  If the fair
market value of the Rights on the date of  distribution  is less than 15% of the
fair market  value of the  previously  held Common  Stock on that date,  the tax
basis of the Rights will be zero  unless the  shareholder  makes an  irrevocable
election to allocate a portion of the basis of the previously  held Common Stock
to the Rights.  Such an allocation would be accomplished as described above. The
election is made by attaching a statement to the  shareholder's  federal  income
tax return for the taxable  year in which the Rights are received and will apply
to all Rights received in the Offering.

     Existing  shareholders  receiving Rights in the distribution  will assume a
holding  period for those  Rights  based upon the holding  period for the Common
Stock previously held.

     Taxpayers,  including existing  shareholders,  acquiring Rights in the open
market will have a tax basis in those Rights equal to the  purchase  price.  The
holding period for Rights  acquired on the open market will begin on the date of
purchase.

Sale or Exchange of the Rights

     If a Columbus  shareholder sells or otherwise  disposes of Rights otherwise
considered  to be Section 306 Stock,  the proceeds  received  will be treated as
ordinary  income to the extent of the fair market value of the Rights on the day
of  distribution.  Any excess of the amount  received  over the tax basis of the
Rights plus the amount  treated as ordinary  income will be  considered  as gain
from the sale of a capital asset  assuming the Rights are a capital asset in the
hands of the holder.

     No loss is recognized upon the sale or disposition of Rights  considered to
be Section  306  Stock.  Such  disallowed  loss is added to the tax basis of the
Columbus common stock otherwise held.

                                       18
<PAGE>

     If an  existing  shareholder  sells all of their  Rights  considered  to be
Section  306 Stock,  and in the same  transaction  completely  terminates  their
interest  in Columbus by selling all of the  Columbus  common  stock  previously
held,  capital  gain or loss will be  recognized  assuming  the  Rights  and the
Columbus common stock are considered as capital assets in their hands. Ownership
of Columbus  Common Stock and Rights by related  parties must be  considered  to
determine complete termination of ownership.

     Shareholders  or investors who sell Rights acquired on the open market that
are not considered to be Section 306 Stock,  will recognize capital gain or loss
on a sale or exchange of the Rights  assuming  the Rights are capital  assets in
their hands and assuming that basis has been allocated to the Rights.

Expiration of Unexercised Rights

     Existing  shareholders  who  receive  Rights in the  distribution  that are
considered to be Section 306 stock will not  recognize a loss on the  expiration
of those Rights. Such loss will be added to the tax basis of any Columbus common
stock retained.

     Existing  shareholders  or investors  who hold Rights not  considered to be
Section  306 Stock will  recognize  a capital  loss on the  expiration  of those
Rights assuming the Rights are capital assets in their hands.

Exercise of Rights

     No gain or loss will be  recognized by existing  shareholders  or investors
upon the exercise of the Rights.  Preferred Stock acquired  through the exercise
of Rights  considered to be Section 306 Stock will also be considered as Section
306 Stock.  The tax basis of the  Rights,  the cash  paid,  and the basis of any
Common Stock surrendered in the exercise for the Preferred Stock will become the
tax basis of the Preferred  Stock in the hands of the  shareholder.  The holding
period will commence as of the date of the exercise.

Conversion of Series A Preferred Stock to Common Stock

     Shareholders  do not  generally  recognize  taxable  gain or loss  upon the
conversion  of preferred  stock to common stock of the same  corporation  if the
conversion  is  accomplished  pursuant  to a  plan  of  reorganization.  If  the
Preferred  Stock being  converted  is  considered  to be Section 306 Stock,  the
Common Stock received will not be Section 306 Stock. However, if the exercise of
the Rights was accomplished in part with Columbus Common Stock, the Common Stock
received upon  conversion  will be Section 306 Stock.  The tax basis and holding
period of the Preferred  Stock  converted to Common Stock will carry over to the
Common Stock received regardless of whether it is Section 306 Stock.

                                       19
<PAGE>

Redemption of the Preferred Stock

     Redemption  of the Preferred  Stock may result in gain being  recognized by
the  shareholder.  To the extent the  Preferred  Stock is treated as Section 306
Stock, the amount realized equal to the lower of Columbus'  earnings and profits
or the fair  market  value of the  Rights  at the date of  distribution  will be
treated as a dividend.  To the extent the amount realized exceeds such value, or
to the extent  shareholders are holding  Preferred Stock which is not considered
Section  306  Stock,  the amount  realized  on  redemption  will be treated as a
dividend or as proceeds from a sale or exchange.  Such determination can only be
made at the time the plan for redemption is contemplated.

     The  above  discussion  of  the  Federal  income  tax  consequences  may be
challenged  by  the  Internal  Revenue  Service.   Should  any  challenge  prove
successful, the income tax consequences could be materially different from those
discussed  above.  The above  interpretation  is only a general  summary  of the
Federal  income  tax  consequences  of the  Offering  and does not  address  any
foreign,  state or local income tax consequences.  The discussion  concerns only
the Federal income tax impact to Columbus  shareholders  and  subsequent  Rights
purchasers,   and  not  any  Federal  tax  impact  to  Columbus.  Each  Columbus
shareholder  and  subsequent  Rights  purchaser  should  consult  his or her own
personal income tax advisor as to the Federal,  foreign,  state and local income
tax impact of the Offering.

                          DESCRIPTION OF CAPITAL STOCK

     The Company is authorized to issue 20,000,000 shares of Common Stock and up
to 5,000,000 shares of preferred stock, no par value  ("Preferred  Stock").  The
summary of certain  provisions of the Company's Amended and Restated Articles of
Incorporation  and Bylaws set forth below does not purport to be complete and is
subject to, and  qualified in its entirety by reference  to, all  provisions  of
such Amended and Restated  Articles of Incorporation  (including the Certificate
of Designation creating the Series A Preferred Stock) and Bylaws.  Copies of the
Amended and Restated  Articles of  Incorporation  (excluding the  Certificate of
Designation)  and Bylaws are incorporated  into this Prospectus by reference.  A
copy of the  Certificate  of  Designation is attached as Exhibit B at the end of
this Prospectus.

Common Stock

     Each share of Common Stock has one vote (subject to the class voting rights
of  holders of the Series A  Preferred  Stock and of any other then  outstanding
Preferred Stock).  The holders of Common Stock are entitled to receive dividends
when and as declared by the Board of Directors  out of funds  legally  available
for such payments. The terms of the Series A Preferred Stock prohibit payment of
dividends on the Common Stock if the Company has not paid all accrued  dividends
on the Series A  Preferred  Stock.  Holders of Common  Stock have no  preemptive
rights to purchase  additional  shares.  Subject to the  preferential  rights of
holders of any then outstanding Preferred Stock, the holders of Common Stock are
entitled  to  share  ratably  in  the  assets  of  the  Company   available  for
distribution  to  stockholders  in  the  event  of  the  Company's  liquidation,
dissolution or winding up.

     The  holders  of  Common  Stock  have no  cumulative  voting  rights in the
election  of  directors.   The  Company's   Amended  and  Restated  Articles  of
Incorporation  also  provides  that the Board of  Directors  be divided into two
classes of approximately equal size, with one class to be elected for a two-year
term at each annual meeting of shareholders.

                                       20

Preferred Stock

     The preferred  stock of the Company is issuable,  from time to time, in one
or more series, with such designations, preferences and relative, participating,
optional or other special  rights,  qualifications,  limitations or restrictions
thereof  as shall  be  stated  and  expressed  in a  resolution  or  resolutions
providing for the issue of such series  adopted by the Board of  Directors.  All
shares of any one series of  preferred  stock are  required to be  identical  in
every  particular,  and all series are required to rank equally and be identical
in all respects,  except  insofar as they may vary with respect to matters which
the Board is expressly authorized by the Company's Amended and Restated Articles
of Incorporation to determine in the resolution or resolutions providing for the
issue of any series of preferred stock. No assurance can be given that the terms
of any series of preferred stock will not materially limit or qualify the rights
of the holders of Common  Stock.  No shares of preferred  stock have been issued
prior to the Offering.

Series A 7% Convertible Preferred Stock

     Up to 400,000 shares of Series A 7% Convertible  Preferred Stock ("Series A
Preferred Stock") will be issued to shareholders of the Company who exercise the
Rights.  Shares of Series A  Preferred  Stock will be issued,  to the extent the
Rights have been  exercised,  promptly after the  expiration  date of the Rights
(the "Issue Date").  The Board may issue up to an aggregate of 2,000,000  shares
of Series A  Preferred  Stock at such time or times as it  chooses,  without the
necessity  for a vote of or  consent by the  holders  of the Series A  Preferred
Stock or holders of Common Stock.  Application  has been made for listing of the
Series A Preferred  Stock on the  American  Stock  Exchange.  The summary of the
terms of the  Series A  Preferred  Stock set  forth  below is  qualified  in its
entirety by  reference to the  Certificate  of  Designation  which the Board has
filed with the  Colorado  Secretary  of State to create  the Series A  Preferred
Stock,  The  certificate,  which is  attached to this  Prospectus  as Exhibit B,
should be reviewed in its entirety  before any decision is made to acquire or to
exercise the Rights.

     Dividends.  Holders of shares of Series A Preferred  Stock will be entitled
to  receive,  when,  as and if  declared  by the Board out of legally  available
funds,  cumulative  dividends from the date of initial issuance of the shares of
Series A Preferred  Stock upon expiration of the Rights at the rate of 7% of the
$25.00  face  value per share,  and no more,  payable  semi-annually.  Dividends
declared  on Series A  Preferred  Stock  will be  payable  semi-annually  on the
fifteenth  days of March and  September,  commencing  _________________________,
1997,  or at such other times and for such  interim  periods,  if any, as may be
determined by Board. Dividends on shares of Series A Preferred Stock will accrue
on a daily  basis  (without  interest or  compounding)  whether or not there are
unrestricted  funds  legally  available  for the payment of such  dividends  and
whether or not such dividends are earned or declared.  Accrued dividends will be
paid only when,  as, and if  declared  by the Board,  which the Board may in its
discretion decline to do. In addition, applicable law prohibits the payment of

                                       21
<PAGE>

dividends to the extent that a corporation would thereafter be unable to pay its
debts as they  become due in the  ordinary  course of  business or to the extent
that the corporation's  total assets would be less than total  liabilities.  The
Company had assets in excess of  liabilities  in the amount of $14,690,000 as of
August 31, 1996,  and the Company  currently  expects that it will have adequate
financial resources to pay, and will be legally capable of paying,  dividends in
the ordinary course on the Series A Preferred Stock for the foreseeable  future.
There can be no assurance,  however, that adverse trends in operating results or
other  unforeseeable  events will not result in insufficient  legally  available
funds to permit payment of dividends or that the Board will not conclude,  based
on  unforeseeable  circumstances,  that funds otherwise  available for dividends
would  better be  applied  for other  corporate  purposes.  Accrued  and  unpaid
dividends may, subject to the foregoing limitations, be paid at any time and, to
the extent so paid,  will be paid without  interest or other amounts  reflecting
the time value of money.

     Liquidation  Preference.  Each  share of Series A  Preferred  Stock will be
entitled to receive a distribution  upon any  liquidation  and winding up of the
Company  (before  any  distribution  is made to holders  of Common  Stock) in an
amount  equal to (i) $25 plus (ii) any  accrued  but  unpaid  dividends.  To the
extent  assets of the  Company  are  insufficient  to pay the full  preferential
amount to which  holders of the Series A Preferred  Stock would be entitled upon
any  liquidation  and  winding up of the  Company,  amounts  available  for such
distribution  would be paid pro rata to holders of the Series A Preferred  Stock
based  on the  number  of  shares  held by each of  them.  After  receiving  the
foregoing  preferential amount, holders of Series A Preferred Stock would not be
entitled to  participate  with  holders of Common  Stock in any other or further
distribution upon a liquidation and winding up of the Company.

     Certain  Limitations on Dividends and  Redemptions of Junior Stock. So long
as any shares of Series A Preferred Stock are outstanding, (i) no dividends will
be paid or declared in cash or otherwise, and no other distribution may be made,
on any stock of the Company ranking junior to the Series A Preferred Stock as to
dividend  rights,  payments on redemption and payments of amounts  distributable
upon the dissolution, liquidation or winding up of the Company ("Junior Stock"),
and (ii) no shares of any Junior Stock may be purchased,  redeemed, or otherwise
acquired by the Company or any subsidiary, and no funds may be set aside or made
available  for any sinking  fund for the  purchase or  redemption  of any Junior
Stock,  unless:  (a) all accrued dividends on all outstanding shares of Series A
Preferred  Stock have been paid, or declared and set aside for payment,  for all
dividend  periods  terminating  on or  prior to the  date of such  Junior  Stock
dividend or distribution  payment,  and (b) the Company is not in default on any
of its  obligations  to  redeem  any  Series  A  Preferred  Stock.  There  is no
prohibition  of payment of  dividends  on any Junior  Stock  solely in shares of
Junior Stock or warrants,  rights or options exercisable for or convertible into
Junior Stock or the redemption,  purchase or other  acquisition of Junior Stock,
solely in exchange for, or through the application of the proceeds from the sale
of,  shares of Junior Stock or warrants,  rights or options  exercisable  for or
convertible into Junior Stock.

     Conversion  Privilege.  Each  share of  Series A  Preferred  Stock  will be
convertible, in whole or in part, at the option of the holder, at any time after
the 60th day after the Issue Date, unless previously  redeemed,  into ___ shares
of Common  Stock of the  Company  (the  "Conversion  Rate").  Except as provided
below,  upon any conversion of shares of Series A Preferred Stock into shares of
Common  Stock,  the Company  will not make any payment or  allowance  for unpaid
dividends,  whether or not in arrears, on converted shares of Series A Preferred
Stock or for previously  declared  dividends or  distributions  on the shares of
Common  Stock  issued  upon  such  conversion.  Holders  of  shares  of Series A
Preferred  Stock at the close of  business  on a record  date for any payment of
declared  dividends  will be entitled to receive  the  dividend  payable on such
shares of Series A Preferred Stock on the  corresponding  dividend  payment date
notwithstanding  the effective  conversion of such shares  following such record
date and prior to the corresponding  dividend payment date.  However,  shares of
Series A Preferred Stock  surrendered for conversion after the close of business
on a record date for any payment of dividends and before the opening of business
on the next succeeding  dividend  payment date must be accompanied by payment in
cash of an amount  equal to the  dividend  on such  shares  attributable  to the
current  dividend  period  which  is to be paid on such  dividend  payment  date
(unless such shares of Series A Preferred  Stock are subject to  redemption on a
redemption  date  falling  between  such record date and such  dividend  payment
date).  A holder of shares of Series A Preferred  Stock called for redemption on
any dividend  payment date will (if such holder is the registered  holder on the
applicable record date) receive the dividend on such shares payable on that date
and will be able to convert such shares after the record date for such  dividend
without paying an amount equal to such dividend to the Company upon  conversion.
The right to convert  shares of Series A Preferred  Stock called for  redemption
will terminate  immediately  before the close of business on the tenth day prior
to related redemption date. See "Optional Redemption" below.

     Conversion  Adjustments.  The Conversion Rate is subject to adjustment upon
the  occurrence  of certain  events  involving  the Company  including,  (i) the
payment by the Company of dividends on outstanding shares of its Common Stock in
shares of capital stock;  (ii)  subdivisions  or  combinations  of Common Stock;
(iii) the issuance by the Company of capital  stock in  reclassification  of its
outstanding  shares of Common  Stock;  (iv) the  issuance  by the Company to all
holders of Common Stock of rights or warrants  entitling them to purchase shares
of Common  Stock at a price per share less than the current  market price of the
Common  Stock;  (v)  distributions  by the  Company to all  holders of shares of
Common  Stock of assets,  evidences  of  indebtedness  or  securities;  and (vi)
mergers or consolidations  of the Company,  sales of all or substantially all of
the Company's assets, and reclassifications of or changes in the Common Stock.

     Mandatory  Redemption.  Each  share of  Series A  Preferred  Stock  (if not
earlier  converted or redeemed)  will be subject to mandatory  redemption by the
Company  (i)  within 60 days after a Change in Control  (as  defined  below) has
occurred, if the Board has not by resolution given its approval of the Change in
Control  prior to its  occurrence,  and (ii)  within two years after a Change in
Control has  occurred,  if the Board has approved the Change in Control prior to
its occurrence,  at the redemption  price then in effect.  A "Change in Control"
means that any  person  other than  Harry A.  Trueblood,  Jr.,  or his estate or
heirs, together with such person's affiliates, controls, by direct or beneficial
ownership (or both), over 50% of the voting power of the capital stock necessary
to elect a majority of the Board.

                                       23

     Optional Redemption.  Shares of Series A Preferred Stock are not redeemable
prior to six months after the Issue Date (the "Initial Redemption Date"), except
under the mandatory redemption  provisions  applicable to a change of control of
the Company that is not approved by the Board. At any time and from time to time
on or after the Initial  Redemption  Date,  the  Company  will have the right to
redeem, in whole or in part, the outstanding  shares of Series A Preferred Stock
at the following per share redemption  prices,  together with accrued but unpaid
dividends (whether or not earned or declared) to the date fixed for redemption:

  Period                                        Redemption Price Per Share

  Issue Date through November 30, 1999:         110% of face value, plus accrued
                                                and unpaid dividends

  December 1, 1999 through                      105% of face value, plus accrued
  November 30, 2005:                            and unpaid dividends

  After November 30, 2005:                      Face value, plus accrued and 
                                                unpaid dividends


If fewer than all the  outstanding  shares of Series A Preferred Stock are to be
redeemed as of any date,  the shares of Series A Preferred  Stock to be redeemed
will be selected by the Company  from  outstanding  shares of Series A Preferred
Stock  pro  rata  (as  nearly  as may  be  practicable)  among  all  holders  of
outstanding shares of Series A Preferred Stock.  Dividends on shares of Series A
Preferred Stock selected for redemption  will cease to accrue,  and the right of
the  holders of such  shares to  convert  such  shares  into  Common  Stock will
terminate  immediately prior to the close of business on tenth day preceding the
related Redemption Date.

     General  Voting Rights.  The holders of Series A Preferred  Stock will have
the right to one vote for each share of Series A  Preferred  Stock held by them,
will be  entitled to notice of any  meeting of  shareholders  of the Company and
will be entitled to vote  together with holders of the Common Stock with respect
to any matter upon which holders of Common Stock are entitled to vote.

     Right  to Elect  Directors  Upon  Dividend  Defaults.  At any time  accrued
dividends  payable on the shares of Series A Preferred  Stock are in arrears and
unpaid in an  aggregate  amount equal to or exceeding  the  aggregate  amount of
dividends payable on such shares for four or more semi-annual  dividend periods,
the holders of the shares of Series A Preferred  Stock,  voting  separately as a
class,  will  have the  right to vote for the  election  of two  directors  (the
"Preferred Stock  Directors") to the Board,  such directors to be in addition to
the number of directors  constituting the Board immediately prior to the accrual
of such right. The right of the holders of shares of Series A Preferred Stock to
vote for the  election of two  Preferred  Stock  Directors  will,  when  vested,
continue  until all  dividends  in arrears  on the shares of Series A  Preferred
Stock have been paid in full and, when so paid,  such right will cease,  subject
always to the same  provisions  for the  vesting of such right in the holders of
the shares of Series A Preferred Stock in the case of further dividend defaults.
The  Preferred  Stock  Directors  will be  elected  by a  majority  of the votes
actually cast by the holders of Series A Preferred  Stock,  and will serve until
such person's resignation or until the Company cures the dividend default.

                                       24

     Class Voting on Additional  Specified Matters. For so long as any shares of
Series A Preferred Stock remain outstanding, the affirmative vote of the holders
at least two-thirds of such outstanding  shares (voting  separately as a class),
given in person or by proxy at an annual  meeting or special  meeting called for
such  purpose,  will be  necessary  before the Company  may (i) amend,  alter or
repeal any of the provisions of its Articles of Incorporation so as to adversely
affect the powers,  preferences or rights of the holders of the shares of Series
A Preferred  Stock then  outstanding or reduce the minimum time required for any
notice to which holders of shares of Series A Preferred  Stock then  outstanding
may be entitled;  or (ii) authorize or issue any capital stock which ranks prior
to, or on a parity  with,  the Series A Preferred  Stock as to dividend  rights,
rights of  redemption  or rights on  liquidation  (except  for the  issuance  of
additional  shares of Series A Preferred  Stock which were  authorized as of the
Issue Date). In order to avoid doubt,  the  Certificate of Designation  provides
that any such amendment,  alteration or repeal that would  authorize,  create or
increase the authorized  amount of any additional shares of Junior Stock or that
would decrease (but not below the number of shares then  outstanding) the number
of authorized shares of Series A Preferred Stock will be deemed not to adversely
affect such powers, preferences or rights and will not be subject to approval by
the holders of shares of Series A Preferred Stock.  Anything in the foregoing to
the contrary notwithstanding,  no consent of the holders of the shares of Series
A  Preferred  Stock  will be  required  if,  at or prior to the time  when  such
amendment,  alteration  or repeal is to take  effect,  provision is made for the
redemption of all shares of Series A Preferred Stock at the time outstanding.

     Transfer Agent and Registrar.  Harris Trust Company of New York will act as
transfer agent and registrar for the Series A Preferred  Stock and will also act
as agent in respect of any  redemption  or  conversion of the shares of Series A
Preferred Stock.

     Shares Nonassessable;  No Preemptive Rights; Retired Shares. Upon issuance,
the shares of Series A  Preferred  Stock  will be fully paid and  nonassessable.
Holders of shares of Series A Preferred  Stock will have no  preemptive  rights.
Shares of Series A Preferred  Stock  redeemed by the Company will be retired and
resume the status of authorized and unissued shares,  without  designation as to
series,  until such  shares  are once more  designated  as part of a  particular
series of preferred stock by the Board.



                                 USE OF PROCEEDS

     The net proceeds from the Offering are estimated to be $__________ assuming
a full  exercise of Rights and payment in cash only.  The net proceeds  from the
Offering would be  $____________ if the maximum number of shares of Common Stock
are tendered as partial payment for the Preferred  Stock.  The net proceeds will
be used by Columbus to reduce (but not  terminate  the existing  line of credit)
most of Columbus'  bank debt (which was  $1,900,000 as of December 31, 1996) and
the  remainder,  if any,  for future  capital  expenditures.  See  "Management's
Discussion  and Analysis of Financial  Condition and Results of Operation" for a
description  of the  terms of such  bank  debt.  Expected  capital  expenditures
include development of proved undeveloped  reserves,  existing drilling projects
(such as the Company's  12.5%  participation  in the drilling and  completion of
several dual lateral oil wells in the Austin Chalk  formation on its  leaseholds
in Louisiana),  exploration costs, and possible property acquisitions that might
become  available.  See  "Management's  Discussion  and  Analysis  of  Financial
Condition and Results of Operations-Recent Activities."

     All  proceeds  from the  Offering  will be held in trust  by  Harris  Trust
Company of New York, the  Subscription  Agent,  until completion of the Offering
and delivery of the Preferred Stock.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The discussion and analysis below  addresses  changes that have occurred in
Columbus'  financial condition and its results of operations during a three-year
period from fiscal years 1993 through 1995 and for the nine-month periods ending
August 31, 1996, and 1995. Also, reference is made to the information  appearing
under  "Selected  Financial  Data,"  as  well as to the  Consolidated  Financial
Statements  and related  notes which appear  elsewhere in this  Prospectus.  The
Company's fiscal year ends on November 30, and all references in this section of
this  Prospectus  to years refer to fiscal  years  unless the context  otherwise
indicates.

     The information  below contains several  forward-looking  statements within
the meaning of the Private Securities Litigation Reform Act of 1995 (the "Reform
Act").  These  statements  involve  inherent   uncertainties,   including  price
volatility, development,  operational and implementation risks, as well as other
factors  that may cause the  actual  financial  performance  of  Columbus  to be
materially different from predicted financial performance. See "Risk Factors."

     The  analysis of economic and  operational  trends from the results of 1993
through 1995 is difficult for two reasons.  First,  the Company in February 1995
divested  itself of its  wholly-owned  Canadian  subsidiary,  CEC Resources Ltd.
("Resources"),   by  means  of  a  subscription  rights  offering  to  Columbus'
shareholders.  The deletion of financial  performance  information  of Resources
from the Company's financial statements as a result of the rights offering makes
it difficult to compare results in 1996 and 1995 to results in prior years.

     Secondly,  the Company  elected to adopt early as of the  beginning  of the
fourth  quarter of 1995  Statement of  Financial  Accounting  Standards  No. 121
("SFAS-121"),  "Accounting  for the  Impairment  of  Long-Lived  Assets  and for
Long-Lived  Assets to be Disposed Of." SFAS-121 requires that an impairment loss
be  recognized  when the  carrying  amount  of an asset  exceeds  the sum of the
undiscounted  estimated  future  cash flow of the asset.  The  Company  reviewed
impairment of oil and gas properties using expected prices and year end provided
reserves which had been significantly  reduced.  Four areas in Texas,  Oklahoma,
New Mexico and North Dakota  indicated that impairment  losses were greater than
previously   estimated  and  that  it  was  prudent  to  elect  early  adoption.
Accordingly,   a  non-cash  loss  of  $3,055,000   ($2,260,000  after  tax)  was
recognized, which was equal to the difference between the carrying value and the
fair value of each asset group. As a result of the adoption of SFAS-121,  future
amortization  and  depletion  expenses  are  expected  to  be  lower  since  the
properties' total carrying value was significantly reduced.

     A non-cash  impairment  loss of $165,000  was  recognized  during the first
quarter of 1996  because a  development  well  drilled in Oklahoma  proved to be
uneconomic and its costs exceeded the remaining cash flows from other  producing
properties in the field.

Liquidity and Capital Resources

     Columbus'  financial  condition  and  operating  results have  continued to
improve in 1996.  As of the end of the first nine months of 1996,  shareholders'
equity was  $14,690,000,  compared to  shareholders'  equity of  $13,186,000  at
November 30, 1995,  despite the Company's  repurchase of 86,100 shares of Common
Stock.  Management believes that existing positive working capital of $1,221,000
and net proceeds  from the Offering,  combined  with the  Company's  anticipated
future cash flow,  should be sufficient to fully fund all expenditures  required
to  develop  the   Company's   existing   undeveloped   reserves  and  to  allow
participation in a modest exploratory  drilling program.  As of the date of this
Prospectus,  the Company also has approximately  $_________  available under its
$7,000,000  borrowing  base  pursuant  to the line of credit with  Norwest  Bank
Denver, N.A. Although the Company may borrow funds up to its available borrowing
base for any corporate  purpose,  management of the Company has designated  bank
debt as the  source  of funds for  acquisitions  of oil and gas  properties  and
entities.

     To  date,  the  Company's  1996  development  program  has been  much  more
rewarding  than that of 1995.  Effective  as of  November  1, 1995,  the Company
completed an acquisition of additional  working  interests in producing  natural
gas wells in several fields near Laredo in Webb and Zapata Counties,  Texas at a
cost of $2.63 million.  The Company completed a second acquisition in the Laredo
area at a cost of $500,000,  effective June 1, 1996.  The Company  utilized bank
borrowings  for both  acquisitions.  Subsequent  drilling  successes  and higher
prices  have  combined  to  make  these  added  working  interests   substantial
contributors to 1996 results.

     For the nine months of 1996, revenues increased by 21% compared to the nine
months of 1995,  due to higher oil and natural gas production and higher prices.
Net  income  of  $1,539,000,  or $0.50  per  share,  for 1996 was a  significant
improvement  over the $501,000 of net income,  or $0.16 per share,  for the nine
months of 1995.  Proved  developed  and  undeveloped  natural  gas and crude oil
reserves as of August 31, 1996,  benefitted  from higher prices,  which restored
some reserves and reduced  depletion  expense for the third quarter of 1996 both
from a BOE unit basis and from a percentage of sales standpoint.

     Management has long believed that the best measure of a company's cash flow
is determined  before any  consideration  is given to working capital changes or
deduction of  exploration  expenses.  This is known as  discretionary  cash flow
("DCF").  Columbus'  DCF for the  first  nine  months  of 1996  was  $4,791,000,
compared to $3,205,000 in 1995 (which included  $362,000 of DCF  attributable to
Resources).  The improvements resulted from higher prices (despite reductions in
revenues  from  swaps,  which are  discussed  more  fully  below)  and  improved
production of both crude oil and natural gas.

     Management  continues its objection to the Financial  Accounting  Standards
Board Statement No. 95 requirement  that operating cash flow be determined after
consideration  of working capital  changes.  Management will continue to reflect
its opinion on this matter in all public  filings and  reports,  because FASB 95
ignores  entirely  the  significant  impact on working  capital of the timing of
income  received  for, or expenses  incurred on behalf of, third party owners in
wells.  FASB 95 has a  particularly  significant  impact  on  Columbus,  because
Columbus  serves as an  operator  but holds a fairly  small  interest in several
properties that have significant levels of expense generating activity.

                                       31

     Sales volume of natural gas averaged 7,412 Mcfd during the third quarter of
1996,  which was up 42% from the  average of 5,221 Mcfd in the third  quarter of
1995; oil sales were 614 barrels per day in the third quarter of 1996,  compared
to 627 in the third quarter of 1995.  Management's stated goal for 1996 had been
to surpass a former  record  level of 2,200 BOE per day by the third  quarter of
1996. The Company has not accomplished this objective for several reasons,  with
the most  significant  being a delay  in  developing  its  Williston  Basin  oil
reserves.  While  production  in  August  1996  approximated  1,874 BOE per day,
several  completed gas wells were either  connected late in the month or will be
completed during the fourth quarter.  It should be noted that production for the
third quarter of both 1996 and 1995 was solely from U.S. operations.

     Columbus'   swaps  of  natural  gas  and  crude  oil  (a  type  of  hedging
transaction)  are  discussed  in  Note 9 to the  financial  statements  in  this
Prospectus.

     The  divestiture  of Resources  resulted in the loss of the Company's  most
profitable source of income from operation and management services. However, the
Company  has been  able to  reduce  operating  expenses,  with the  result  that
U.S.-only  operation and management  services have been  profitable  despite the
divesture of Resources.

     Columbus had  outstanding  borrowings  of $3,200,000 as of August 31, 1996,
against its line of credit with Norwest Bank Denver,  N.A., of which  $2,700,000
had been  borrowed  in  December  1995 and  $500,000  in June 1996 for  property
acquisitions (as discussed above). The credit agreement was amended as of August
30, 1996,  to reduce the LIBOR  interest  rate from LIBOR,  plus 1 3/4% to LIBOR
plus 1 1/2%, and to extend the revolving period of the loan from July 1 1997, to
July 1,  1999 and the  maturity  of the term  loan  from July 1, 2000 to July 1,
2003. This loan is  collateralized  by Columbus' oil and gas properties.  At the
end of the third quarter of 1996, the ratio of bank debt to shareholders' equity
was  0.22,  and the  ratio  of bank  debt to total  assets  was  0.15.  The debt
outstanding  at the end of the third  quarter of 1996 used a LIBOR  option at an
average  interest rate of 7.35%.  From  September  through  December  1996,  the
outstanding debt was further reduced by $1,300,000, to $1,900,000.

     During the first nine months of 1996, capital expenditures  incurred on oil
and gas properties  totaled $5,849,000  (including  acquisitions of $2,981,000).
These  expenditures  were primarily  directed  toward  development  drilling and
recompletions  in the South Texas and Gulf Coast areas and to prospect  costs in
the new Louisiana AMI discussed below.

     Columbus  continued its Common Stock  repurchase  program  during the first
nine months of 1996. It acquired an additional  86,100 shares during this period
out of a 300,000-share repurchase program authorized in February 1995. The Board
authorized purchases to a maximum price of $8.75 and required that all purchases
be made  from  available  cash and not with bank  borrowings.  The  Company  has
acquired  284,000 shares out of the 300,000 shares  originally  authorized under
the repurchase  program.  The Company has suspended its Common Stock  repurchase
program pending completion of the Offering.

Results of Operations

     Generally,  revenues and expenses for the first nine months of 1996 are not
comparable to the first nine months of 1995 because of the Company's divestiture
of Resources as of February 24, 1995.  Likewise,  revenues and expenses for 1995
are not  comparable to revenues and expenses for 1994.  Excluding the operations
of Canada from the first nine months of 1995, the Company's  revenues  increased
by 35% in the first nine months of 1996 and  operating  income  increased  167%,
compared to the first nine months of 1995,  due  primarily to increased  oil and
gas production and improved  prices.  Excluding the operations of Resources from
1995 and 1994,  the Company's  revenues  decreased by 15% in 1995, and operating
income  decreased 51%  (excluding  consideration  of the impairment  loss),  due
primarily  to  declining  crude oil and natural gas prices and higher  depletion
expense.  Interest and  litigation  expenses  decreased in 1995,  but a $141,000
retirement and separation accrual offset this reduction.

     The Company had its highest ever  revenues in 1994,  but  operating  income
decreased 9% from  results in 1993,  which itself had been a record year for the
Company.  Litigation  expenses in 1994 were mostly related to lawsuits that have
now been settled.  Interest  expense rose in 1994 because of increased  interest
rates and amounts  borrowed  compared to 1993.  Net earnings in 1995 (before the
impairment  charges) were at their lowest level since 1991. Net earnings in 1994
declined from net earnings in 1993,  because of increased  exploration  expense,
litigation expense, interest expense,  depreciation and depletion charges, and a
higher  effective  tax rate.  Net earnings in 1993 were at a record high for the
Company,  even before the cumulative effect of an accounting change,  because of
increased gas  production at better prices and because the collapse in crude oil
prices occurred in the last half of the year.

Oil and Gas Operations

     The discussion of the Company's oil and gas operations  below is based upon
production and average prices for the United States and Canada.

     The changes in the  components  of oil and gas revenues  during the periods
presented are summarized as follows:

                                                Production
                              Price Change    Quantity Change     Revenue Change

     Natural gas revenues for the first nine months of 1996 were 56% higher than
the similar period in 1995 because of improved prices and the effect of property
acquisitions  and  newly  developed  wells.  Average  prices  rose  27% in 1996,
compared  with the first nine  months of 1995.  Increased  demand  and  severely
depleted storage levels following an extended winter heating season  contributed
to this  price  improvement.  Revenues  in the  first  nine  months of 1996 were
reduced by $282,000  ($0.14 per Mcf) from  natural gas swaps,  while the Company
had  $284,000  ($0.17 Mcf) of revenue  gains from natural gas swaps in the first
nine months of fiscal 1995.

     Oil  revenues for the first nine months of fiscal 1996 were up 23% over the
similar  period in 1995 as a result of an 11% increase in average  prices and an
11%  sales  volume  increase.  Crude  oil  production  improved  because  of the
commencement  of  production  from two new Jackson  sand oil wells in the Sralla
Road field in 1996, which was sufficient to overcome normal  production  decline
elsewhere.  Oil  revenues  and average  prices for the first nine months of 1996
have been reduced by $165,000  ($.91 per barrel) due to the Company's  crude oil
swap for 1996. The Company did not participate in any crude oil swaps in 1995.

     Natural gas revenues and production  for 1995  decreased  compared to 1994,
primarily as a result of lower prices and declining gas production in the Sralla
Road field and the fields  near  Laredo,  Texas.  Occurrence  of a  reversionary
working  interest  reduction in the Company's  most  productive  gas well in the
Laredo area  accounted for about one-half of the reduced gas production and more
than offset new production  from  additional  connections in Texas and Oklahoma.
Average  prices for  natural  gas  decreased  11%  compared to 1994 but began to
increase toward the end of 1995. Average prices in the spot market are currently
quite high due to cold early winter weather.

<PAGE>

     Oil revenues in the U.S. for 1995 were up 8% from 1994 as a result of a 10%
increase in the average price  received.  Crude oil prices  continued to dictate
deferral of any full scale  development  program for  undeveloped  oil  reserves
located in the  Williston  Basin.  However,  a moderate  amount of drilling  was
planned  for 1996 as a result of the 1996  crude oil swap,  which  affords  some
protection from previous drastic downturns in prices,  which had halted drilling
plans before drilling had commenced.

     U.S. natural gas revenues and production for 1994 were significantly higher
than 1993 as a result of new gas well  completions  in Texas and Oklahoma.  Even
with the  inclusion  of the revenue  gains from the 1994  natural gas swap,  the
average price realized in 1994 still decreased 12% compared to 1993. The Company
experienced normal decline in oil production in 1994, but a few wells, which had
been made  uneconomic  by oil prices  and whose  production  had been  curtailed
awaiting  improvement  in oil prices,  were  returned to  production  during the
fourth quarter of 1994.  Also, the flooding of a river near Houston in late 1994
which  required  shutting-in  several  wells  was  primarily  responsible  for a
reduction  in oil  production  of 77 barrels of oil per day compared to the 1994
average and also resulted in a reduction in gas production of 2,100 Mcfd for the
fourth quarter of 1994, compared to the third quarter of 1994.

     In the  U.S.,  natural  gas  revenues  and  production  for 1993  increased
significantly over 1992 because of a higher level of new gas well completions in
the Sralla Road field near Houston and in the Laredo,  Texas area.  Also,  daily
allowables  increased  as of April  1993 from 700 Mcfd to 1,300 Mcfd for each of
the Jackson sand gas wells in the Sralla Road field.  Average natural gas prices
also improved in 1993 compared to 1992.

     U.S. oil  revenues for 1993 were down 11% from 1992,  primarily as a result
of a 10%  decrease in oil prices and because  the  initial  incentive  discovery
allowable in 1991 for the Vicksburg formation of 340 barrels per day was reduced
to 215 barrels per day per well  beginning on October 1, 1993. Oil production in
the Williston Basin that had been generated from several  recompletions  in 1992
also declined in 1993 from initial  production  rates,  and new oil wells in the
Williston  Basin  that  had  been  planned  for  1993  were   postponed.   Water
encroachment  in one of the Vicksburg  wells in the Sralla Road field caused its
oil productivity to fall below its allowable.

     U.S. oil prices have  fluctuated  with the same wide swings  experienced in
world crude oil prices during recent years.  In 1993,  crude oil prices declined
gradually  throughout the year until the fourth quarter when a dramatic collapse
occurred. In 1994, oil prices experienced a very slow recovery, with the average
price for the year  being  about  13%  below  1993.  In 1995,  crude oil  prices
declined in  mid-year  months but  recovered  by  year-end,  so that the average
annual prices were higher than 1994.

     No  comparisons  of oil and gas revenues and operations in Canada from 1995
to 1994 are made because of the Company's  divestiture  of Resources in February
1995. Natural gas revenues increased by 5% in 1994 compared to 1993;  production
increased by 11%,  while average  prices  decreased by 5%.  Beginning in mid-May
1994, several wells that were completed,  or were recompleted in new formations,
were  connected  to the Carbon  gas  processing  plant,  which was  expanded  in
November  1994.  Additional gas from new East Carbon wells was added in November
and December of 1994,  which positively  affected 1995 revenues.  The production
decline of the Ghost Pine 14-34 well  flattened  and  provided  29% of net lease
level  cash  flow.  Revenues  from oil and plant  liquids  declined  14% in 1994
because of a 14% decrease in prices from 1993. Natural gas revenues increased in
1993, as prices improved over 1992, and production  volumes decreased by only 2%
as a result of an expanded  1993  development  program  and the  addition of one
well's  production  because  of the  occurrence  of a 33%  reversionary  working
interest.  Oil and liquids prices and  production  volumes were down 7% for 1993
compared to 1992.

     On a BOE basis,  lease  operating  expenses in the U.S.  for the first nine
months of 1996 were  slightly  higher  than the  similar  period in 1995  ($2.85
compared  to  $2.73  in  1995),   and  total  lease   operating   expenses  were
substantially  higher because of additional wells,  several expensive workovers,
and the effect of property  acquisitions in 1996. Operating costs in the U.S. as
a  percentage  of revenues  have  decreased  to 19% for the first nine months of
1996,  compared to 27% for the first nine months of 1995,  primarily as a result
of higher product prices in 1996.

     Lease operating expenses in the U.S. increased 19% in 1995 compared to 1994
because of several extensive  workovers that were performed in an effort to make
some wells more  economic.  Lease  operating  costs on a BOE basis for 1995 were
$2.78,  compared  to  $1.93  for  1994.  Lease  operating  expenses  in the U.S.
decreased 7% in 1994 compared to 1993,  because  there were fewer  workovers and
because  several  oil wells  with high  operating  costs were shut in due to low
crude oil  prices.  Also,  most well  additions  in 1994 were gas  wells,  which
usually have lower operating costs.  Lease operating expenses were up 9% in 1993
compared  to 1992,  as new  lease  operating  expense  for U.S.  gas wells had a
relatively small percentage  increase  compared to added revenues.  Accordingly,
operating  costs in the U.S.  increased  as a  percentage  of revenues to 22% in
1995, compared to 15% in 1994 and 16% in 1993.

     The Company's operating costs in Canada in 1994 declined from 1993, both in
amount and as a percentage  of revenues,  primarily  because  several more older
wells with relatively  higher  operating  costs were  supplemented by new wells.
Fees paid for both processing and  compression  were lower as a result of a 1994
litigation settlement agreement with the operator of the Carbon field and plant.
The settlement also reduced operating expenses on an ongoing basis.

     Production  and property taxes have  approximated  9% to 10% of revenues in
1996, 1995 and 1994. Production and property taxes were higher in 1993 (10.3% of
revenues),  primarily because gas production in Texas was relatively higher than
oil  production.  (Texas  imposes  higher  taxes on gas  production  than on oil
production.)  However,  gas production  taxes in Texas were offset  partially by
tight sands tax exemptions in the B. R. Cox field.  In the U.S.,  production and
property taxes are not always directly  proportionate to revenues,  because some
local  jurisdictions  base such taxes upon  reserve  evaluations,  as opposed to
actual  revenues or  production.  Production  and property  taxes in Canada have
previously averaged approximately 5% to 6% of oil and gas revenues.

Operating and Management Services

     This  segment of the  Company's  business is comprised  of  operations  and
services conducted on behalf of third parties and includes compressor rentals.

     Profit from operating and management  services for U.S.  operations for the
first nine months of 1996 was aided by savings from staff reductions made at the
beginning of the fourth  quarter of 1995.  There was a $172,000  profit for U.S.
operating and management services during the first nine months of 1996, compared
to a $121,000 profit for the equivalent period in 1995.

     Prior to the  Company's  divestiture  of  Resources,  the Company  received
operating  service  revenue in Canada from its share of  processing  fees at the
Carbon area liquid extraction plant.  Those revenues also included fees from the
processing of Resources'  own gas, but no profit was generated from that portion
of revenues  since it was offset by a  commensurate  increase in Columbus'  well
operating expenses.

     Operating and management  services U.S.  revenue has increased during 1994,
1995 and the  first  nine  months  of 1996.  Until  divested  in 1995,  Canadian
operations had contributed  greater  operating  margins.  In 1995, U.S. revenues
improved  because of additional  billings for operator  services  related to 3-D
seismic testing  program and because of adjustments  resulting from past audits.
These factors  contributed  to a $199,000  profit in 1995 for the U.S.  segment,
compared to a $197,000  profit in 1994.  In the B.R. Cox field in October  1993,
the operator of record  engaged the Company to serve as contract  operator of 15
existing wells.  This increased U.S.  service  revenues  sufficiently in 1994 to
generate a small profit.

     The  settlement of Resources'  lawsuit  against the former  operator of the
Carbon gas processing plant is discussed in Note 10 to the financial statements.
The Company had not accrued prior  receivables in the amount of CDN$210,000  due
to the  litigation  but  accrued  them in the  third  quarter  of 1994  when the
settlement was reached.  As a part of the  settlement,  operating and management
services   expenses  were  also  reduced  by  CDN$167,000   for  prior  operator
overcharges,  and revenues were increased by CDN$43,000 for adjustments to plant
processing  fees. The Company agreed to royalty  adjustments of CDN$38,000 which
had been  claimed  by the  former  operator,  but this had no new  effect as the
royalty  adjustments had previously been accrued as a payable.  Costs associated
with the legal  expenses  for this  settlement  were  included as an  operations
expense.

     In Canada, the operating and management services segment showed a profit of
$559,000 in 1994 and  $561,000 in 1993,  primarily  due to third party gas plant
processing fees.

     Specific  amounts of  reimbursed  revenues from  operating  and  management
services received from formerly operated partnerships are disclosed in Note 7 of
the Notes to the Financial Statements.

Interest Income

     Interest income is earned primarily from short-term investments whose rates
fluctuate  with changes in commercial  paper rates and the prime rate.  Interest
income  decreased  in the first nine  months of 1996 to  $107,000,  compared  to
$128,000 in the first nine months of 1995,  primarily  as a result of a decrease
in the amount of investments and lower short-term  interest rates. This increase
in  interest  income was  primarily  the result of an  increase in the amount of
investments  early in the year (after the  divestiture  of Resources) and higher
short-term interest rates. The increase in interest income in 1994 was primarily
the result of higher short-term interest rates.

General and Administrative Expenses

     General and  administrative  expenses are those expenses that relate to the
direct  costs of the Company and that do not  originate  from the  operation  of
properties or the providing of services.  Corporate  expense  represents a major
part of this category, although other nonbillable expenses are included.

     The Company's general and administrative  expenses in the first nine months
of 1996  compared to the first nine months of 1995 were lower  because of salary
and staff reductions made in August 1995 and because  incentive  bonuses totaled
only  $83,000  for the first nine  months of 1996 (all  non-cash),  compared  to
$110,000 for the similar  period in 1995.  The Company's  U.S.  expenses in 1995
were 6% higher than in 1994; employee salary and staff reductions were offset by
higher  compensation  from cashless stock option  exercises,  increased fees for
regular listing on the American Stock  Exchange,  shareholder and stock transfer
expense,  professional  services (which included the fees of a second  petroleum
engineering  firm),  and a higher matching  contribution to the Company's 401(k)
Plan.  Expenses  for 1994 were  higher  than 1993  because  of  employee  salary
increases plus  incentive  bonuses of $111,000 that were awarded to all officers
(including the Chief Executive  Officer) based on achievements of the Company in
1993. Also, employees had higher medical claims under the Company's self-insured
plan, and the Company made a higher  matching  contribution  to its 401(k) Plan.
Employee benefit costs were lower in total for 1993 compared to 1992 because the
ESOP was  terminated  in 1993,  but  expenses  related to the  exercise of stock
options (which is a non-cash charge) were higher in 1993 than in 1992.

Depreciation, Depletion and Amortization

     Depreciation,  depletion  and  amortization  of  oil  and  gas  assets  are
calculated  based upon the units of  production  compared to proved  reserves of
each field. The expense is not only directly related to the level of production,
but also is  dependent  upon  past  costs to find,  develop  and  recover  those
reserves.  Depreciation  and  amortization  of  office  equipment  and  computer
software are also included in the total charge in 1995 and 1994.

                                       38
<PAGE>

     During  1993  and  1992,  depletion  expense  for oil  and  gas  properties
increased in approximate  proportion to the increase in production.  During 1995
and 1994,  depletion  expense for oil and gas  properties  increased  by greater
percentages   than   the   increase   in   production.   Contributing   to   the
disproportionately  higher depletion expense were lower gas and crude oil prices
during 1995 and 1994,  which tended to reduce  estimated  reserves,  shorten the
estimated  reserve  life,  and  change  the  economic  limits of  certain of the
Company's  properties;  these factors  resulted in a higher  depletion  rate for
those affected properties. The carrying values of certain oil and gas properties
after the impairment  loss that occurred with the adoption of SFAS 121 effective
September 1, 1995 were  reduced.  This helped  reduce  depletion  expense in the
fourth  quarter of 1995.  The depletion rate increased in 1993 compared to 1992,
due in part to production  increases in the Zenith field waterflood (which had a
high per unit depletable cost basis), and by the payment of anticipated costs to
develop certain proved undeveloped reserves in the Sralla Road field.

     For the first nine months of 1996, the depletion  rate for U.S.  operations
was $3.89 per BOE,  compared to $4.31 for the similar  period in 1995. For 1995,
the depletion  and  depreciation  rate for the Company  (both  Canadian and U.S.
operations)  was $3.83 per BOE,  compared to $2.78 per BOE for 1994 and $2.73 in
1993.  These amounts are still below the industry average  primarily  because of
historically low finding costs. However, if the relatively lower depletion rates
of Canadian gas properties are excluded, then the depletion charge in 1995 would
have been $4.21 per BOE.

     During 1994,  the Company wrote down U.S. oil and gas  properties  that had
been fully  depleted  in  previous  years by  $17,342,000,  as a charge  against
accumulated depreciation, depletion, and amortization. There was no gain or loss
to the Company since the properties had been fully depleted.

Exploration Expense

     In general,  exploration expense includes the cost of Company-wide  efforts
to acquire and explore new  prospective  areas.  Until Resources was divested in
February 1995, the Company's  exploration expense was primarily  attributable to
geological  consulting  work provided in Canada plus limited  seismic expense in
Canada and the U.S.. The successful efforts method of accounting for oil and gas
properties requires that the cost of drilling unsuccessful exploratory wells and
other exploratory costs be currently expensed.

     During 1996, an exploratory  well drilled in Oklahoma  proved  non-economic
and $77,000 was expensed. During the first quarter of 1995, seismic survey costs
of $46,000 were incurred in Canada and  expensed.  Also,  undeveloped  leasehold
costs in North Dakota were impaired by $69,000 in 1995. All of these contributed
to an  exploration  expense of  $245,000  for 1995.  In 1994,  two  unsuccessful
exploratory  wells  were  drilled  at a net  cost to the  Company  of  $307,000,
including one in Saskatchewan,  Canada,  and one in Harris County,  Texas, about
two miles west of the Sralla Road field;  the Texas well also condemned  certain
leaseholds,  while the Company allowed other leases to expire and together these
resulted in an additional  charge of $202,000.  In 1993, an exploratory  well in
Canada found non-commercial hydrocarbon shows and was plugged and abandoned at a
net cost of $49,000 plus a total of $24,000 of undeveloped  leasehold costs were
impaired and expensed.  These  exploration  expenses have reduced  reported cash
flow from  operations,  in  addition  to net  earnings,  even  though  they were
discretionary  expenses;  however those expenses were added back for purposes of
calculating DCF.

Loss on Asset Disposition

     During 1993,  the Company sold its  marginally  profitable  gas  properties
located in Mississippi  and recognized a loss on disposition of $228,000  (since
these  properties  were  all  in  one  successful   efforts   accounting  pool).
Interestingly, these were the first properties owned by the Company and were the
source of the  Company's  name  (because of their  location on the  Columbus Air
Force Base).

Interest Expense

     Interest expense varies in direct proportion to the amount of bank debt and
the level of bank interest  rates.  The average bank interest rate paid for U.S.
debt in 1995, 1994 and 1993 was 7.9%, 5.9%, and 5.3%, respectively,  compared to
7.3% for the first nine months of 1996.

Income Taxes

     The Company adopted  Statement of Financial  Accounting  Standards No. 109,
"Accounting for Income Taxes" ("SFAS 109"),  effective at the beginning of 1993,
which was one year earlier than mandated.  The Company's  income tax position is
somewhat  complex.  Resources'  income was consolidated  with the Company's U.S.
income, until Columbus'  divestiture of Resources in 1995. Also, the utilization
of net operating loss  carryforwards  by the Company has been complicated by two
"change of ownership"  transactions  under  Section 382 of the Internal  Revenue
Code, one of which occurred on October 1, 1987 and the other on August 25, 1993.
Furthermore, a quasi-reorganization occurred on December 1, 1987, which requires
that  benefits from net operating  loss  carryforwards  or any other tax credits
that arose prior to the  quasi-reorganization  be credited to additional paid-in
capital  rather  than to income;  only post  quasi-reorganization  tax  benefits
realized can be credited to income.

     As a result of the use of net operating loss  carryforwards,  the Company's
Federal income tax  obligations  have been limited to the  "alternative  minimum
tax," and, in general,  the Company has had a current Federal income tax rate of
less than 2% of pre-tax  earnings.  Beginning in 1997, the Company  expects that
the only  operating loss  carryforwards  available will be from periods prior to
the first  Section 382  ownership  change;  utilization  of those  benefits  are
presently  limited to  approximately  $904,000 per year,  so that the  Company's
current  Federal tax provision and liability may increase in 1996 and thereafter
unless an active drilling program is maintained.  In addition,  the Company pays
state  income  taxes and,  until the  divestiture  of  Resources  in 1995,  paid
Canadian taxes on Resources' income.

     As of November 30, 1993, certain  carryforward tax benefits were considered
to be  realizable on a "more likely than not" basis,  and the related  valuation
allowance  was reduced  (including a reduction in the post  quasi-reorganization
valuation  allowance of $339,000).  This reduced the 1993  effective tax rate by
8%. The  disqualifying  disposition  of  incentive  stock  options  exercised by
employees  during 1993 allowed the Company to take a tax  deduction of $165,000,
but that amount had to be added to additional  paid-in capital and was not shown
as a book tax benefit.

                                       40
<PAGE>

     As  of  November  30,  1994,  additional  carryforward  tax  benefits  were
considered realizable and the post quasi-reorganization  valuation allowance was
reduced by $303,000.  A deduction of $29,000 for  disqualifying  dispositions of
incentive stock options was taken and was added to additional  paid-in  capital,
along with $182,000 for the reduction in the pre quasi-reorganization  valuation
allowance.  The 1994  effective  income  tax rate  increased  because  of higher
Canadian  deferred  taxes.  No tax credit for U.S. income taxes was available to
offset the effect of payment of Canadian taxes.

     During 1995, the U.S. net deferred tax asset was reduced to $638,000, which
is comprised of a $1,290,000 current deferred tax asset and a $652,000 long-term
tax liability.  The deferred tax asset increased by an estimated $537,000 during
1995.  The valuation  allowance was increased by a net of $96,000,  even after a
reduction of $233,000 for the Canadian deferred taxes of Resources. No provision
was  required  for  Canadian  deferred  taxes  following  the  divestiture.  The
estimated effective tax rate for 1995 is a 26% book tax benefit.

     During the first nine months of 1996,  the U.S.  net deferred tax asset was
reduced to a net liability of $165,000,  which is comprised of a $96,000 current
deferred  tax  asset and a  $261,000  long-term  tax  liability.  The  estimated
utilization of deferred tax assets was  $1,080,000  during the first nine months
of 1996, and the valuation allowance has remained unchanged for such period. The
estimated effective tax rate for the first nine months of 1996 was 38%. See also
Note 6 to the  consolidated  financial  statements for a further  explanation of
income taxes.

Other Income/Expense

     During 1993, other expense included a loss on the exchange rate of the U.S.
dollar compared to the Canadian dollar.

Canadian Exchange Rates

     Until the  divestiture of Resources by the Company in 1995, the fluctuation
in the Canadian dollar affected the consolidated oil and gas revenues, expenses,
and average  sales  price per unit of  Resources  (which  were  reported in U.S.
dollars).  Such  currency  fluctuations,  in turn,  affected  cash  flow and net
earnings reported by the Company during such periods.

Effects of Changing Prices

     The United States economy  experienced  considerable  inflation  during the
late 1970's and early 1980's but in recent  years has been fairly  stable and at
low levels. The Company,  along with most other U.S. business  enterprises,  was
then  and  will be  affected  by any  recurrence  of such  economic  conditions.
Recently, inflation has had a minimal effect on the Company.

                                       41
<PAGE>

     In recent years,  oil and natural gas prices have  fluctuated  widely.  The
Company's  results of operations  and cash flow are affected by changing oil and
gas prices. Oil and gas prices have been significantly  influenced by regulation
by various governmental  agencies,  by the world economy, and by world politics.
Operating  expenses  have  been  relatively  stable  but,  when  analyzed  as  a
percentage  of  revenues,  may be  distorted  to a degree since they appear as a
larger  percentage of revenues when lower product prices  prevail.  Drilling and
equipment  costs  have  risen  in the last  several  years.  Competition  in the
industry  can  significantly  affect the cost of acquiring  leases,  although in
recent years  competition  has lessened as more  operators  have  withdrawn from
active exploration  programs.  Inflation,  as well as a recessionary period, can
cause  significant  swings in the  interest  rates that the Company pays on bank
borrowings.  These factors are  anticipated  to continue to affect the Company's
operations, both positively and negatively, for the foreseeable future.

Recent Activities

                           Recent Drilling Activities

     Subsequent to the end of the third  quarter of 1996,  one 78% owned natural
gas well (the Wiggins Unit #1) was completed in the upthrown  fault block of the
Sralla Road oil field,  which has extended the productive  limits of its gas cap
by almost one mile southwest.  The well had similar  thickness (about 6 feet) to
other Jackson sand wells in the area, but the zone appeared to be more porous on
logs which has contributed to the well's  capability of producing natural gas at
rates several times its state-assigned  allowable of about 1,400 Mcfd.  However,
even at this  restricted  flow  rate,  it  contributed  over a 10%  increase  in
Columbus' daily gas production  following its connection in early November 1996.
In  addition,  the  Wiggins  Unit #1 has been  yielding  approximately  35 to 40
barrels of condensate per Mcf of gas production.

     The aforementioned well represented the only operated drilling activity for
the fourth quarter of 1996. Several previously proposed 1996 development program
wells had to be deferred,  primarily  because of the recent increased demand for
drilling rigs resulting from escalating  product prices.  The Company was also a
2%  participant in a completed  non-operated  gas well in the Laredo area during
the fourth quarter of 1996. Columbus was the operator in an unsuccessful attempt
at a  recompletion  of a  behind-the-casing  gas zone in a B. R. Cox field which
produced uneconomic rates of gas with water.

                                       42
<PAGE>

     The Company  completed a 3-D seismic program early in the fourth quarter of
1996,  which was aimed at  locating  the best  structural  well site at which to
drill a new 90%-owned  12,400 foot Red River oil producer in the Southeast Froid
field in Montana.  This twin well will  replace an  existing  well that has been
pumping  for about ten years from a depth of about 7,600 feet due to a collapsed
section  of the 5 1/2 inch  production  casing  at about  8,000  feet.  However,
Columbus was unable to contract  for a large  drilling rig required to drill the
well during the fourth  quarter and  postponed  that project until January 1997.
This  replacement  well should drain the remaining Red River oil reserves in the
field much more quickly,  while assuring that the Company can hold a substantial
leasehold block with continued economic production for several more years. Also,
management  expects to use the cased well bore of the present  well to produce a
different oil zone,  which will require cutting a window  immediately  above the
collapsed  interval and then drilling  about 2,000 feet in a  side-tracked  hole
down  to  the  Winnipegosis  formation,  which  previously  produced  oil  in  a
structurally lower well. While conducting this 3-D seismic program,  the Company
encountered several leads which tended to support old 2-D seismic data which had
previously  indicated  the possible  existence of two or more separate Red River
structures  on this  acreage  block.  Based upon this data,  Columbus  has added
several hundred  additional acres of new leases and has scheduled a supplemental
3-D seismic  program for March 1997.  At present,  Columbus  holds a 90% working
interest  in  about  2,000  acres  of  leaseholds  immediately  surrounding  the
Southeast  Froid field and covers  potential new  structures.  Encouraged by the
current oil price levels,  Columbus expects that the Williston Basin in general,
and this Southeast Froid field area in particular,  will be a significant source
of future  additions  to daily oil  production  during  1997.  At $1 million per
completed Red River oil producer and $600,000 for a 12,000-foot dry hole,  these
prospects will command a substantial  part of the Company's  drilling budget for
at  least  the  next  year  or  more.  Also,  Columbus  expects  to  drill a few
short-radius  laterals from its existing cased Mission  Canyon  producers in the
Williston Basin during 1997 based upon the reported successes by other operators
who have utilized this new technology.

     The Company's fourth quarter oil prices have increased  substantially  over
the average  price of $18.91 per barrel  realized for the third quarter of 1996,
with recent prices  approximating  $23.00 per barrel. Also, this improvement has
carried over into the first quarter of fiscal 1997 with oil prices  occasionally
surpassing  $24.00.  Natural gas prices,  which  averaged  $2.12 per Mcf for the
third  quarter,  fell  off to only  $1.85  in  September,  but  rose to $2.29 in
October,  and appear to have  averaged  almost  $3.00 per Mcf  during  November.
During December,  natural gas prices reached levels of about $4.50 per Mcf for a
portion of the month,  which suggests that natural gas revenues for 1997's first
quarter may be the highest ever for a fiscal quarter.

     Notwithstanding the previously  mentioned recent shortage of drilling rigs,
the  Company's  1996  drilling  program  activity  resulted in its largest gross
participation in wells since 1993, when Resources'  Canadian  drilling  activity
was  included  in the  count,  and the most  ever  when  U.S.-only  activity  is
considered.  The Company  participated in a total of two (0.675 net) exploratory
wells,  both of which proved to be dry holes. One of the dry holes had initially
indicated it might be a gas discovery,  but after being acidized to increase its
gas rate, the well began to produce at uneconomic  water  production  levels.  A
total of 22 development wells (6.55 net) were drilled during 1996,  resulting in
two (1.01 net) oil producers, 14 (2.60 net) natural gas producers, and six (2.95
net) dry holes.

                         Update on New Area of Interest

     Columbus   added  an  entirely  new  area  of  interest  in  late  1995  in
mid-Louisiana  when it joined with three co-venturers to promote the acquisition
of leaseholds and the drilling of deep (15,500 feet vertical depth) wells,  with
single and dual horizontal extensions therefrom. The co-venturers formed a three
township  Area of Mutual  Interest  ("AMI") in the deep Austin  Chalk trend in a
known productive area prior to the time that the activity level began to heat up
in the area as a result of the  successful  completion  of several  high  volume
producers  in fields to the  northwest  of the AMI  extending  west to the Texas
border. The Company has previously  emphasized the potential  importance of this
area,  initially in its annual  report on Form 10-K for the year ended  November
30, 1995, and thereafter in each of its regular  quarterly  shareholder  reports
(as well as a Special  Interim  Report  dated  September  27, 1996  specifically
devoted to the Company's involvement in the area).

     Management believes that this prospect area has the potential to add rather
quickly the most sizable new oil reserves of any of its core areas.  This AMI is
located in St. Landry and Avoyelles  Parishes,  and the  leaseholds are known to
overlie a 250-foot  zone of  geo-pressured,  fractured  Austin  Chalk  which has
received substantial  publicity recently in trade publications.  There have been
several dual lateral wells along the trend that were drilled  horizontally  from
bore hole  vertical  depths  ranging  from  14,000 to 17,000  feet and that were
completed  as high  capacity  natural  gas/condensate  and crude oil  producers.
Initial  reported  capacity rates have ranged from 2,000 to 6,000 barrels of oil
or condensate per day, along with 2.5 to 25 Mmcfd for some of those wells. A few
uneconomic  wells have also been completed along the trend, but those appear not
to have dampened the  enthusiasm of the various major  participants  in this new
play.

     The Company and its three  individual  co-venturers had proposed to promote
several  companies to  participate in the drilling of two wells on its initially
assembled block of issued and option leases  amounting to  approximately  24,000
acres, but in the spring of 1996, a large independent operator,  Belco Oil & Gas
Corporation  ("Belco"),  agreed to acquire a 75% working interest in that block.
Belco also agreed to the previously  designated three township AMI and undertook
to acquire  substantial  additional  acreage  for all  accounts.  Because of the
intervening  rise in  acreage  bonuses  along the trend  following  the  initial
assemblage, the co-venturers (including Columbus for 6.25%) realized a profit on
the base acreage block. The co-venturers were to also be carried by Belco for an
after-payout  25%  participation  in a new well drilled from the  grassroots  to
approximately  15,000 feet vertical depth with dual laterals of about 4,000 feet
in length.  Belco also  undertook  to meet the group's  farmout  obligations  to
re-enter and drill a single  lateral hole from a previously  abandoned  vertical
cased  wellbore  within the AMI. This farmout  originally  was taken in order to
have a cased vertical well to test new drilling  technology and drilling  fluids
that the co-venturers planned to utilize based on the assumption that they would
maintain  operatorship  instead of yielding  same to Belco.  Columbus has had no
direct  participation rights or expenses in the re-entry well farmout obligation
following Belco's assumption of the obligation.

     Belco did complete  that farmout  re-entry well in August 1996 and has made
one press release  regarding its initial test results,  which stated that it had
an  initial  flow  rate of 2,500  BOPD and 2.7  Mmcfd  from a single  3,900-foot
lateral hole, which was drilled  horizontally from a 15,333 foot vertical depth.
This test was conducted  through a 1/2 inch choke with a flowing tubing pressure
of 1,000 psi.

                                       44
<PAGE>

     As  previously  indicated  in its  Special  Interim  Report  in  September,
management reported that Belco had subsequently  acquired additional  leaseholds
within the AMI that had brought  the total to more than  44,000  gross acres and
39,700 net acres. At that date,  Columbus owned varying  interests from 6.25% to
12.5% under all issued leases and had a 6.25% interest in  approximately  14,000
acres of leasehold  options.  The leasehold  options are  exercisable in 6-month
intervals,  in minimum  segments  of 2,000  acres of new  leases,  each having a
5-year term.  Assuming all of those  leasehold  segments are exercised  over the
next three years,  Columbus and its co-venturers will not only have a fully paid
up 25% participation in those newly issued leases but also will realize a profit
in excess of $300,000 each.

     As set forth in the  September  report to  shareholders,  Columbus'  12.50%
working  interest in the recently  added 16,000 gross acres within the AMI could
be reduced by 3.125% (to 9.375%) if one of the coventurers  exercised his option
to acquire that interest at cost before October 28. The  co-venturer in fact did
exercise the option; however, on November 29, 1996, the Company paid $275,000 in
cash and  issued  30,000  shares  of its  Common  Stock to  acquire  all of that
co-venturers'  interest in the AMI. This transaction  brought Columbus' interest
up to a uniform 12.50% throughout the assembled 44,000 acre block plus the 6,000
acres of additionally  acquired leaseholds.  The 6,000 additional acres have yet
to be  identified  or assigned  by Belco.  The  transaction  also  included  the
purchase of the  co-venturer's 15% working interest in an existing vertical well
bore  completion  in the Austin Chalk and his  overriding  royalty  interests of
approximately  1.3% and 1.6% in two existing  Austin  Chalk  single  lateral oil
wells,  which the  co-venturer  owned  prior to the  formation  of the AMI.  The
co-venturer  retained his right to receive up to $300,000 of the profit due upon
Belco's exercise of the remaining leasehold options.

     Columbus had expected that Belco would have long since  commenced  drilling
the carried- interest grassroots dual lateral well. However, delays in receiving
approval from government regulatory agencies for the surface location forced the
deferral of contract  arrangements  for a drilling  rig. In order to shorten the
timetable  for  commencement  of  drilling  operations,  the  co-venturers  have
recently  negotiated an amendment to Belco's original agreement which called for
the  co-venturers  to have a 25% carried  working  interest after payout in that
grassroots well. The new arrangement permits spreading that undertaking over two
wells by allowing  for a portion to be  satisfied by utilizing a well bore owned
by all parties which already has casing in place almost to the top of the Austin
Chalk. This Morrow #1-23 well is located in Section 23 of Township 2 South Range
4 East around which a  1,960-acre  rectangular  unit is being  created such that
acceptable  length  dual  laterals  of about  4,000  feet each can be drilled by
Belco. The Company and its co-venturers will be responsible for paying their 25%
(12.5% to Columbus)  share of the cost of  re-entering  the existing  cased well
bore, analyzing the integrity of the existing casing and adding a liner into the
top of the Austin Chalk,  if required.  Thereafter,  Belco, at its sole expense,
will drill the two dual lateral holes from this wellbore,  run slotted liners in
each, add  production  equipment in the vertical hole, and complete with surface
equipment as appropriate.  Belco,  Columbus and its co-venturers will each share
in the initial  revenues from this first well. The  co-venturers  will receive a
percentage  of their 25% of the revenue  stream that is in  proportion  to their
respective costs paid compared to total expenditures  incurred by all parties in
re-entering and placing the well on production.  Following  recovery by Belco of
its  disproportionate  share of the total costs,  the full 25% working  interest
revenues  will  flow to  Columbus  and its  co-venturers  (instead  of the lower
percentage of revenues during the payout period).

                                       45
<PAGE>

     The second  grassroots  well site,  assuming it is  drilled,  will have its
vertical  wellbore  located on the  section  line  between  Section 20 and 29 of
Township 2 South,  Range 5 East and  another  1,960- acre unit is to be declared
for this well.  The same cost and  percentage of revenue  sharing  approach will
apply to this second  grassroots well, except in this well the roles essentially
are  reversed.  That  is,  Belco  will  be  responsible  for  paying  all of the
expenditures  necessary  to  drill  and case  the  well to a  vertical  depth of
approximately 15,000 feet in preparation for the drilling of dual lateral holes.
At that point,  the Company and its  co-venturers  will pay 25% of the  expenses
(one-half of which will be borne by Columbus)  required to drill two laterals of
approximately  4,000 feet, run slotted liners,  and install downhole  production
equipment and surface facilities required to place the well on production.  Once
again,  Columbus and its co-venturers  will realize a percentage of their 25% of
revenue   stream  which  equals  a  fraction,   determined  by  their  share  of
expenditures  as the numerator and the total of all  expenditures by all parties
as the denominator.  When Belco has fully recovered its disproportionate  costs,
then once  again the full 25%  revenue  stream  will  flow to  Columbus  and its
co-venturers.

     Assuming one or both of the wells are  successfully  completed (as to which
there can be no  assurance),  the  length of the  payout  period for each of the
wells will be dependent upon the total costs incurred and the initial completion
rates achieved,  as well as the rate of production decline  thereafter.  Initial
completion  rates  will be  determined  by the  extent of the  natural  vertical
fractures  encountered in the lateral portions of the well bores.  These in turn
will also have a significant  effect on the subsequent  rate of decline plus the
eventual oil and natural gas  reserves  recovered  from each well bore.  Without
actual drilling,  what will be encountered while drilling the laterals cannot be
forecasted  with any  accuracy  whatsoever.  Therefore  the Company is unable to
forecast the payout period for either of the two wells or to state whether there
will even be a payout.  However,  based on the  performance of a few wells which
have recently been  completed in this same Austin Chalk interval along the trend
to the  northwest of the AMI,  payouts as short as three to six months have been
experienced  but  apparently  a few of the wells may never  recover  all  costs.
Management  expects that the success of these first two wells will be determined
not only by the  degree of  fracturing  encountered  but also on the  ability of
Belco to  complete  the wells  without  excessive  costs.  If  Columbus  is only
moderately successful and participates in the 25 or so possible locations on its
leasehold  interest  which could be drilled over the next five years,  then this
new core area has the  potential  to  significantly  increase  Columbus'  proved
developed crude oil reserves.

     Management is confident that leaseholds are located "on trend," since there
have been numerous  wells that have already been drilled within this AMI through
the Austin Chalk on the way to the deeper high  pressure  Tuscaloosa  formation.
Logs from those wells have  exhibited a fairly  uniform  interval in prospective
zone of the fractured  Austin Chalk having about 250 feet in thickness.  Several
of those wells  encountered  such severe  fracturing in that same interval while
drilling  the Austin  Chalk that the wells were later  completed  in the zone in
vertical  well bores.  These  completions  occurred  several  years ago,  before
present horizontal drilling  technology was available.  Some of those cased well
bores are located on leases in which  Columbus  holds a 12.50%  interest,  which
could  contribute to future cost savings by allowing the drilling of one or more
laterals from such cased well bores.

                                       46
<PAGE>

     Current  plans are for Belco to build  location  and  begin  operations  by
re-entering  the Morrow well in Section 23 during  January  1997.  Management is
hopeful  that the delays in  obtaining  approval of the surface  location of the
second  well will  have been  overcome  so that  drilling  at that well site can
commence shortly thereafter.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
         Columbus Energy Corp.

         We  have  audited  the  accompanying  consolidated  balance  sheets  of
Columbus Energy Corp. and subsidiaries as of November 30, 1995 and 1994, and the
related  consolidated  statements of operations,  stockholders'  equity and cash
flows for each of the three years in the period ended  November 30, 1995.  These
consolidated  financial  statements  are  the  responsibility  of the  Company's
management.  Our  responsibility is to express an opinion on these  consolidated
financial statements based on our audits.

         We conducted our audits in accordance with generally  accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance about whether the  consolidated  financial  statements are
free of material  misstatement.  An audit includes  examining,  on a test basis,
evidence  supporting the amounts and disclosures in the  consolidated  financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
consolidated  financial  statement  presentation.  We  believe  that our  audits
provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Columbus Energy Corp. and subsidiaries as of November 30, 1995 and 1994, and the
consolidated  results of their  operations  and their cash flows for each of the
three years in the period ended November 30, 1995, in conformity  with generally
accepted accounting principles.

         As  explained  in  Note 2 to  the  consolidated  financial  statements,
effective  September 1, 1995,  the Company  changed its method of accounting for
the  impairment  of  long-lived  assets  and  as  explained  in  Note  6 to  the
consolidated  financial  statements,  effective  December  1, 1992,  the Company
changed its method of accounting for income taxes.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
               (Information with respect to the nine months ended
                     August 31, 1996 and 1995 is unaudited)

(1) FORMATION AND OPERATIONS OF THE COMPANY

     Columbus  Energy  Corp.   ("Columbus")   was  incorporated  as  a  Colorado
corporation  on October 7, 1982 primarily to explore for,  develop,  acquire and
produce  oil and  gas  reserves.  Columbus'  wholly-owned  subsidiaries  are CEC
Resources Ltd. ("Resources") and Columbus Gas Services, Inc. ("CGSI"). Resources
activity  was only  included  through  February 24, 1995 when it was divested by
Columbus by a rights offering to its shareholders (see below).  Columbus and its
subsidiaries  are referred to in these Notes to the Financial  Statements as the
"Company".

     As of June 1, 1985,  Consolidated  Oil & Gas, Inc.  formed a master limited
partnership,  Consolidated  Energy Partners L.P. (the  "Partnership"  or "CPS").
Under the terms of the  Partnership  agreement,  Columbus  was made the managing
general  partner and as such had all  management  authority  with respect to the
operations of CPS.  Consolidated  served as an associate general partner of CPS.
Columbus  owned  1%  and  also  served  as  the  managing   general  partner  of
Consolidated  Operating  Partners L.P. ("COP") which was 99% owned by CPS as its
sole limited  partner.  During 1989, the oil and gas properties of COP were sold
and both CPS and COP were dissolved effective November 30, 1989 (see Note 4).

     On February 24, 1995,  Columbus completed a rights offering to the Columbus
shareholders  to purchase  one share of  Resources  at  U.S.$3.25  cash plus two
subscription rights. One right was distributed as a dividend for each share held
of record on January 27, 1995.  All 1,500,000  shares of Resources  common stock
were subscribed (and  oversubscribed)  yielding an aggregate of $4,875,000.  The
total value  assigned to the rights on its books was  $582,000  for the dividend
portion of the  purchase of  Resources  shares.  A deduction of $126,000 for the
costs of the offering was recorded.  No gain or loss can be recognized  for book
purposes in a spin-off.  The combination of the cash offering price of $3.25 per
share  plus the  value of the  rights  dividend  assigned  was equal to the U.S.
historical  book cost of Columbus'  investment  in  Resources.  No taxes are due
Revenue  Canada as a result of this  divestiture of common stock because the tax
basis exceeds the proceeds received upon disposition.

(2) ACCOUNTING POLICIES

     The consolidated  financial statements of the Company have been prepared in
accordance with generally accepted accounting  principles and require the use of
managements' estimates. The following is a summary of the significant accounting
policies followed by the Company.

                                      F-11

                              COLUMBUS ENERGY CORP.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (continued)
               (Information with respect to the nine months ended
                     August 31, 1996 and 1995 is unaudited)

     Consolidation

     The accompanying  consolidated financial statements include the accounts of
Columbus and its wholly-owned subsidiaries,  CGSI and Resources through February
24,  1995.  All  significant  intercompany  balances  have  been  eliminated  in
consolidation.

     Cash Equivalents

     For purposes of the  statement  of cash flows,  the Company  considers  all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash  equivalents.  Hedging  activities  are  included  in cash  flow from
operations in the cash flow statements.

     Oil and Gas Properties

     The Company  follows the successful  efforts  method of  accounting.  Lease
acquisition  and development  costs  (tangible and intangible) for  expenditures
relating to proved oil and gas  properties  are  capitalized.  Delay and surface
rentals are charged to expense in the year incurred.  Dry hole costs incurred on
exploratory  operations are expensed.  Dry hole costs associated with developing
proved fields are  capitalized.  Expenditures  for additions,  betterments,  and
renewals are  capitalized.  Geological and  geophysical  costs are expensed when
incurred.

     Upon sale or  retirement  of proved  properties,  the cost  thereof and the
accumulated depreciation or depletion are removed from the accounts and any gain
or  loss  is  credited  or  charged  to  income  if  significant.   Abandonment,
restoration,  dismantlement  costs and salvage  value are taken into  account in
determining  depletion  rates.  These  costs are  generally  about  equal to the
proceeds from equipment salvage upon abandonment of such properties. Maintenance
and repairs are charged to operating expenses.

     Provision for  depreciation  and depletion of capitalized  exploration  and
development costs are computed on the unit-of-production  method based on proved
developed  reserves of oil and gas, as estimated by  petroleum  engineers,  on a
property by property basis. Prior to September 1, 1995, an additional  valuation
provision  was  made if  total  capitalized  costs  of oil  and gas  properites,
excluding  unproved  properties,  exceeded  (1) the present  value of future net
revenues from estimated production of proved oil and gas reserves using constant
prices  discounted  at 10% less (2) income tax  effects  related to  differences
between book and tax basis of the properties.  Unproved  properties are assessed
periodically to determine whether they are impaired.  When impairment  occurs, a
loss is recognized by providing a valuation allowance.  When leases for unproved
properties expire, any remaining cost is expensed.  Depreciation of other assets
are provided on the straight line method over their estimated useful lives.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (continued)
               (Information with respect to the nine months ended
                     August 31, 1996 and 1995 is unaudited)

     The Company uses crude oil and natural gas hedges to manage price exposure.
Realized  gains and losses on the hedges are  recognized in oil and gas sales as
settlement occurs.

     The Company follows the entitlements method of accounting for gas balancing
of gas  production.  The Company's gas imbalances are immaterial at November 30,
1995 and 1994.

     Effective for the fourth  quarter  beginning  September 1, 1995 the Company
adopted Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of  Long-Lived  Assets and for  Long-Lived  Assets to be Disposed Of"
("SFAS 121").  This  statement  prescribes  the accounting for the impairment of
long-lived  assets,  such as oil  and  gas  properties.  An  impairment  loss is
reported as a component of income from continuing  operations.  Adoption of this
statement resulted in an impairment loss (non-cash charge) of $3,055,000 for the
fourth quarter 1995 and was recognized as impairment  expense to the oil and gas
business segment.  The Company reviewed the impairment of oil and gas properties
for each successful efforts pool. The B. R. Cox field in Texas and the Oklahoma,
New Mexico and North Dakota property pools were determined to be impaired and an
impairment loss equal to the difference  between the carrying value and the fair
value of the pool was  recognized.  Fair value was  estimated to be a discounted
present  value  of  expected  future  net  cash  flows  with   appropriate  risk
consideration over the economic life of the reserves.

     Quasi-reorganization

     In fiscal 1988, the Board of Directors adopted a corporate resolution which
approved  a  quasi-reorganization  effective  December  1, 1987 and  transferred
$13,441,000 from additional paid-in capital to offset the accumulated deficit.

     Other Property and Equipment

     Gains and losses from  retirement or  replacement  of other  properties and
equipment  are included in income.  Betterments  and  renewals are  capitalized.
Maintenance and repairs are charged to operating expenses.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (continued)
               (Information with respect to the nine months ended
                     August 31, 1996 and 1995 is unaudited)

     Income Taxes

     The Company files a  consolidated  income tax return with CGSI.  Resources,
its Canadian  subsidiary,  was also included in the consolidated U.S. income tax
return  through  February 24, 1995 before  terminating  with  completion  of the
divestiture.  Resources  was also subject to tax under  applicable  Canadian tax
law.  Columbus and its  consolidated  subsidiary  have executed a tax allocation
agreement  which  provides for an  allocation  and payment of U.S.  income taxes
based upon each Company's separate tax liability calculation.

     Foreign Currency Translation

     Canadian assets and liabilities were translated into U.S. dollars using the
exchange  rate in  effect at year  end.  Canadian  revenues  and  expenses  were
translated using average exchange rates for each period.  Adjustments  resulting
from  these   translations   were   accumulated  in  a  separate   component  of
stockholders'  equity.  Foreign  currency  transaction  gains or  losses,  which
primarily  represented  exchange gains or losses resulting from the denomination
of current intercompany balances into U.S. dollars, were included in determining
net income for prior period.  Such gains or losses are not  significant  for the
periods presented.

     Operating and Management Services

     The  Company  recognizes  revenue for  operating  and  management  services
provided  to other  companies  and  non-operating  interest  owners in which the
Company has no economic interest. The Company receives overhead fees, management
fees and revenues related to gas marketing, compression and gathering.

     The cost of providing such services is expensed and shown as "operating and
management services" cost.

     Earnings Per Share

     Earnings per share are computed using the weighted average number of common
shares outstanding. Stock options are included as common stock equivalents, when
dilutive, using the treasury stock method. Historical amounts have been adjusted
for the 10% stock dividend distributions, in 1995 and 1994.

Accounting for Stock-Based Compensation

     The Financial  Accounting  Standards Board issued  Statement No. 123 on the
"Accounting  for  Stock-Based  Compensation".   This  statement  prescribes  the
accounting and reporting standards for stock-based  employee  compensation plans
and is effective for the Company's 1997 fiscal year unless adopted earlier.  The
Company has not decided if it will adopt this  standard or simply make pro forma
disclosures as the alternative provided by the standard.

Unaudited Interm Periods

     The financial statements contain all adjustments (consisting only of normal
recurring  accruals)  which,  in the opinion of  management,  are  necessary  to
present fairly the financial  position of the Company at August 31, 1996 and the
results of its  operations  and cash flows for the nine months  ended August 31,
1996 and 1995.  The  results  of  operations  for such  interm  periods  are not
necessarily indicative of results to be expected for the full year.

(3) OIL AND GAS PRODUCING ACTIVITIES

     The following tables set forth the capitalized costs related to oil and gas
producing  activities,  costs  incurred  in oil  and gas  property  acquisition,
exploration and development activities,  and results of operations for producing

     For the years ended  November 30, 1995,  1994 and 1993, the Company had the
following customers who purchased production equal to more than 10% of its total
revenues. The following table shows the amounts purchased by each customer.

                     1995                 1994                1993

Customer A    $2,027     27.9%     $1,755      13.4%   $ 2,881      25.9%
Customer B     2,635     36.2       4,072      31.0      2,740      24.6

     In the Company's  judgment,  termination  by any purchaser  under which its
present sales are made would not have a material impact upon its ability to sell
its production to another purchaser at similar prices.

(4) INVESTMENT IN PARTNERSHIP

     Columbus  was  formerly  the  managing  general  partner  of CPS,  and also
operated almost all oil and gas properties owned by its subsidiary  partnership,
COP. When these  partnerships  were  dissolved  effective  November 30, 1989, no
partners  received  a cash  distribution  from  their  investment  in CPS as the
proceeds from the sale of the properties  were less than the bank debt and other
partnership liabilities.

     Columbus,  as managing  general  partner of COP,  and  Columbus as managing
general  partner and  Consolidated  as associate  general  partner of CPS had an
obligation to pay for the respective  partnership's costs incurred.  Included in
other current  liabilities  as of November 30, 1994 and 1995 and August 31, 1996
is $122,000,  $16,000 and $-0-,  respectively,  which represented remaining cash
available to pay any valid claims that might  become  payable  related to either
liquidation  or prior  operations.  During 1995,  a settlement  was reached with
Jicarilla Apache Tribe relative to their claims for additional  royalty owed for
the period 1985  through  1992 from gas wells on their  leaseholds  in which COP
owned varying interests and Columbus was operator. COP's share of the settlement
was $95,000 which was paid from the available $122,000 on hand.

(5) LONG-TERM DEBT

     The Company has a Credit Agreement  ("Agreement") with Norwest Bank Denver,
N.A.  ("Bank")  having a borrowing  base which has been recently  reduced at the
request  of   Columbus   to   $7,000,000,   which  is  subject  to   semi-annual
redetermination  for any  increase  or  decrease.  On January 5, 1996 the Credit
Agreement was amended to extend the revolving period and maturity date. The loan
now  revolves  until  July 1,  1997  and  then in its  entirety  converts  to an
amortizing term loan which matures July 1, 2000. The credit is collateralized by
a first lien on U.S. oil and gas  properties.  The interest rate options are the
Bank's prime rate or LIBOR plus 1 3/4%. In addition,  a commitment fee of 1/4 of
1% of the average unused portion of the credit is payable quarterly.  As amended
and restated on October 23, 1996 the Agreement  extended the revolving period to
July 1,  1999 and the  maturity  date to July 1,  2003  and  reduced  the  LIBOR
interest rate to LIBOR plus 1 1/2%.

     At November 30, 1995 outstanding borrowings on the revolving line of credit
were  $1,600,000 and the unused  borrowing base available was $5,400,000 and the
$1,600,000 bore interest at LIBOR rates of 5.82% plus 1 3/4%.

     The Agreement as amended provides that certain  financial  covenants be met
which  include a minimum  net worth of  $8,300,000  plus 50% of  cumulative  net
income after  November 30, 1991, a quarterly  calculation  of a current ratio of
not less than 1.0:1.0 and a ratio of funded debt to  consolidated  net worth not
greater than 1.25:1.00.  Columbus has complied with these  covenants.  Under the
terms of the  Agreement,  Columbus is permitted to declare and pay a dividend in
cash so long as no default has occurred or a mandatory  prepayment  of principal
is pending.

     The scheduled payments of long-term debt are as follows (in thousands):
                                      At 11/30/95          At 8/31/96

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (continued)

                     August 31, 1996 and 1995 is unaudited)

     The Company files a consolidated  income tax return with its subsidiary and
has executed a tax  allocation  agreement  which  provides for an allocation and
payment of U.S.  income taxes based upon each  company's  separate tax liability
calculation.

     The net operating loss  carryforwards and percentage  depletion  deductions
are for U.S.  tax purposes  only.  For Canadian  income tax  purposes,  when the
annual  taxable  income  of  Resources   exceeded  its  available  Canadian  tax
allowances and deductions for that year,  current income taxes were provided and
a tax liability  recorded.  Canadian  taxes were  currently  payable in 1994 and
1993.  Consolidated  U.S.  income  taxes are payable  only when  taxable  income
exceeds available U.S. net operating loss carryforwards and other credits.

     Pursuant  to  provisions  enacted  as part of the Tax  Reform  Act of 1986,
utilization  of these  corporate  tax  carryforwards  in any one taxable year is
limited  if a  corporation  experiences  a 50%  change  of  ownership.  Columbus
experienced such a change of ownership in October, 1987 effectively limiting the
utilization  of  pre-change  ownership  net  operating  losses to  approximately
$900,000  in each  subsequent  year.  Subsequent  additional  ownership  changes
accumulated  to more  than 50% by  August  25,  1993  thereby  causing  a second
ownership  change to occur.  This  second  change  limited  the  utilization  of
post-1987  net  operating  losses to  $1,300,528 in 1993 and $848,137 in 1994 so
that Columbus was not able to utilize the remaining post-1987 net operating loss
carryforwards of approximately $593,000 until fiscal 1995 or later.

     The Company adopted  Statement of Financial  Accounting  Standards No. 109,
"Accounting for Income Taxes" ("SFAS 109") effective  December 1, 1992. SFAS 109
requires the asset and  liability  approach be used to account for income taxes.
Under this method,  deferred tax liabilities and assets are determined  based on
the temporary  differences  between financial  statement and tax basis of assets
and  liabilities  using  enacted  rates in  effect  for the  year in  which  the
differences  are  expected  to  reverse.  U.S.  tax assets  (net of a  valuation
allowance)  primarily result from net operating loss  carryforwards,  percentage
depletion and certain accrued but unpaid employee  benefits.  U.S.  deferred tax
liabilities   result  from  the  recognition  of  depreciation,   depletion  and
amortization  in different  periods for  financial  reporting  and tax purposes.
Canadian  deferred tax assets  consisted of the tax  attributes of  carryforward
costs that had expended but not yet utilized as tax  deductions  while  deferred
tax liabilities resulted from temporary differences in amortization of costs.

     Because of the Company's previous 1987 quasi-organization,  the adoption of
SFAS 109 requires the Company to report the effect of its net deferred tax asset
arising prior to December 1, 1987 as an increase in stockholders'  equity rather
than  as an  increase  to net  earnings.  The net  deferred  tax  asset  arising
subsequent to the  quasi-reorganization  was a credit to income and was reported
separately as a "cumulative  effect of change in method of accounting for income
taxes".

     The   cumulative    effect   (benefit)   of   $992,000   related   to   the
post-quasi-reorganization net deferred tax asset resulting from adoption of SFAS
109 was recognized in the first quarter of 1993. The cumulative effect (benefit)
of $125,000 related to the pre-  quasi-reorganization net deferred tax asset was
credited to additional paid-in capital in stockholders' equity. In addition, the
cumulative effect (benefit) of $102,000 related to foreign currency  translation
adjustment  was  credited to that  account in  stockholders'  equity.  The total
benefit of $1,219,000 was recorded as a deferred tax asset.

     During fiscal 1995, certain U.S. tax assets (shown in the table below) were
utilized.  Projected taxable income caused the Company to increase the valuation
allowance during the year by $96,000 which increased from the net loss.

deferred tax assets and liabilities and changes were as follows (in thousands):

     For U.S.  Alternative  Minimum Tax purposes  the Company had net  operating
loss  carryforwards  of  approximately  $8,500,000 as of November 30, 1995.  The
Company also has percentage  depletion  carryforwards of $2,300,000 which do not

     The Canadian  carryforwards  were utilized to the extent possible to reduce
Canadian  taxable  income.  U.S.  taxable  income,   which  included  Canada  in
consolidation  until the sale of  Resources  shares on February  24,  1995,  was
reduced by the Canadian taxes paid using a foreign tax deduction or as a foreign
tax credit. Therefore, the consolidated tax benefit realized was insignificant.

     Realization  of the future  tax  benefits  is  dependent  on the  Company's
ability to generate  taxable income within the carryfor ward period.  Based upon
the proved  reserves as of November  30, 1995 as well as  contemplated  drilling
activities,  but excluding  revenues from any possible future increase in proved
reserves, management believes that taxable income during the carryforward period
will be  sufficient  to partially  utilize the NOL's before they expire.  Of the
total  valuation  allowance of  $1,737,000  as of November 30, 1995,  $1,407,000
relates  to  pre-quasi-reorganization  tax assets  and the  balance of  $330,000
relates to post-quasi-  reorganization tax assets. In future periods,  reduction
of the  pre-quasi-reorganization  portion  of the  valuation  allowance  will be
credited   to   additional   paid-in   capital  and   reduction   of  the  post-
quasi-reorganization  portion of the  valuation  allowance  will be  credited to
income.

     Estimates of future  taxable  income are subject to  continuing  review and
change because oil and gas prices  fluctuate,  proved  reserves are developed or
new reserves added as a result of future drilling activities,  and operation and
management services revenue and expenses vary. A minimum level of $11,000,000 of
future  taxable  income will be necessary to enable the Company to fully utilize
the net operating  loss  carryforwards  and realize the gross  deferred U.S. tax
assets of  $4,032,000.  This level of income can be achieved  using the value of
proved reserves reported in the year end November 30, 1995 standardized  measure
of net cash flows but this does not give total assurance that sufficient taxable
income  will be  generated  for  total  utilization  because  of the  volatility
inherent  in the oil and gas  industry  which  makes  it  difficult  to  project
earnings in future  years due to the  factors  mentioned  above.  There is a net
deferred  tax asset of  $638,000  calculated  as of  November  30,  1995,  after
deducting the valuation  allowance.  The valuation allowance was increased a net
$96,000 even after a reduction of $233,000 which  originally had been the amount
provided for the Canadian  deferred taxes and was no longer needed following the
divestiture.

(7) RELATED PARTY TRANSACTIONS

     Columbus,   as   managing   general   partner,   previously   had   certain
responsibilities to CPS and COP.  Additionally,  Columbus is contingently liable
for any debts and obligations of COP, excluding the non-recourse  long-term debt
to the bank, even though there has been a dissolution of CPS and COP. This would
only occur after liquidation proceeds available have been exhausted. Columbus is
not aware of any such debts or obligations of COP that it may be liable for that
would exceed the amount available therefor.

     Certain direct and indirect  general and  administrative  costs incurred by
CPS and COP were  paid  for by  Columbus  and  reimbursed  by CPS and  COP.  The
following  table  sets  forth   reimbursements   (included  with  operating  and
management services revenue) received for each period from COP.

     On October 28,  1992,  the Board of  Directors  approved an Employee  Stock
Purchase  Plan  ("Plan")  to begin  January 1, 1993,  which was  approved by the
shareholders  at the 1993  annual  meeting.  Under  the Plan a total of  220,000
shares were reserved from  authorized  unissued common stock from which payments
by  participants  into the Plan will be  utilized  to  purchase  shares  and the
Company will contribute an amount of shares  equivalent to 25% of those payments
with vesting to occur  semi-annually  which will be issued out of the  Company's
treasury  stock.  For the  fiscal  1995 and 1994  years a total of  $17,000  and
$24,000 match, respectively, was accrued as expense by the Company. The price of
the shares  will be the average  trading  price  during each six month  purchase
period or the ending  price,  whichever is less.  During  fiscal 1994 a total of
14,298 shares were  purchased  (2,875 shares from treasury stock for the Company
contribution of 25%) at an average cost of $9.43 per share. During fiscal 1995 a
total of 13,532 shares were purchased  (2,719 shares from treasury stock for the
Company  contribution of 25%) at an average cost of $8.01 per share. During nine
months  ended  August 31, 1996 a total of 12,394  shares were  purchased  (2,492
shares from treasury  stock for the Company  contribution  of 25%) at an average
cost of $5.74 per share.

     The Company  previously had an Employee Stock Ownership Plan ("ESOP"),  for
Columbus and its domestic subsidiaries from 1987 until its termination effective
November  30,  1992.  At November  30, 1992 upon  termination  of the ESOP,  the
outstanding  ESOP loan balance of $394,104  was paid and 76,229  shares not paid
for or allocated to the ESOP  participants were returned to Columbus as treasury
stock  (reduced by 21,870 shares in 1993 after final  Internal  Revenue  Service
determination).

     During 1993 the Board of Directors  authorized  purchase from the market up
to  350,000  shares  of  common  stock  (375,000  shares  after  stock  dividend
adjustment)  to be held as  treasury  stock.  A total  of  249,200  shares  were
purchased  during  fiscal  1993 at an average  cost of $9.18 per  share.  During
fiscal 1994 an  additional  80,500  shares were  purchased at an average cost of
$9.32 per share.  This was  followed by 45,300  shares  purchased  during  first
quarter 1995 at an average cost of $8.56 per share.

     Another 300,000-share repurchase authorization was approved by the Board in
February  1995,  restricted to a maximum  purchase  price of $8.75 per share.  A
total of 197,900 shares were purchased  during fiscal 1995 at an average cost of
$7.29 per share and 86,100  shares were  purchased  during the nine months ended
August 31, 1996 at an average cost of $6.73 per share.

(9) COMMITMENTS AND CONTINGENT LIABILITIES

     The  Company's   Articles  of   Incorporation   and  By-Laws   provide  for
indemnification of its officers,  directors, agents and employees to the maximum
extent  authorized  by the Colorado  Corporation  Code,  as amended or as may be
amended,  revised or  superseded.  In  addition,  the Company  has entered  into
individual indemnification  agreements with its officers and directors,  present
and past,  which  agreements  more  fully  describe  such  indemnification.  The
indemnification  rights provided under these  agreements had been invoked by the
officer/director  defendants  who had  been  named in the  Adversary  Proceeding
described in Note 10 below and in "Item 3 - Legal Proceedings".

     Lease - In June 1991,  Columbus  executed a lease for office  space for its
present  building  which  provides  for  monthly   payments  of  $11,123,   plus
inflationary adjustments to an annual base operating expense, for a period of 60
months from October 1991 through  October 1996. The total rent expense for 1995,
1994 and 1993 was approximately  $126,000,  $129,000 and $158,000  respectively.
Columbus has renewed the lease for an  additional  two years  through  September
1998 at a base rate of $13,536 per month. Future rental payments, without regard
to operating cost adjustments, required under this lease as of November 30, 1995
are  $138,000,  $162,000  and  $135,000  for fiscal  years 1996,  1997 and 1998,
respectively.

     Columbus  is  self-insured  for  medical  and  dental  claims  of its U. S.
employees and  dependents as well as any former  employees or dependents who are
eligible and elect coverage under COBRA rules. Columbus pays a premium to obtain
both  individual and aggregate  stop-loss  insurance  coverage.  A liability for
claims  incurred  before year end but not yet paid is included in other  current
liabilities.

     During 1994,  Columbus  hedged natural gas prices by selling  100,000 Mmbtu
per month for the twelve  month  period from May 1994  through  April 1995 at an
average  daily  price of $2.12 per Mmbtu.  The "swap" was  matched  against  the
calendar  monthly average price on the NYMEX and settled monthly  resulting in a
gain of $204,600  for the period from May  through  November  1994 and a gain of
$283,900  during fiscal 1995 before its expiration in April 1995. The gains were
included in oil and gas sales revenues.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (continued)

                     August 31, 1996 and 1995 is unaudited)

     The Company has entered into two new swaps of natural gas prices by selling
60,000 Mmbtu per month for the period from April 1996 through  November  1996 at
$1.74 per Mmbtu  while the second  swap is for the same  period and  quantity at
$1.88 per Mmbtu. These amounts  represented  approximately 65% of Columbus' then
gas  production.  To partially  protect itself against  possible  escalating gas
prices in October  and  November  1996,  the  Company  purchased  NYMEX  futures
contracts  for two months for 60,000  Mmbtu of natural gas at $1.805 and $1.875,
respectively.  These options would limit the Company's  potential loss for those
two months to the  difference  between those prices and the $1.74 Mmbtu price of
the original swap.

     Columbus  also  entered  into a swap of crude oil prices by selling  10,000
barrels per month for the twelve month period from January 1996 through December
1996 at an average  daily price of $17.25 per barrel with a cap of $19.50 on the
upside  should crude oil futures soar as a result of some world  calamity.  This
amount  represents  approximately  50% of its current  monthly  production.  The
difference  between the hedge price and the actual  daily  closing  price on the
NYMEX and is settled monthly.  Based upon recent futures prices of crude oil the
Company  may  recognize  a loss in the early  months  but may show a gain in the
latter months.

     The  Company's  natural  gas and crude oil swaps are  considered  financial
instruments  with  off-balance  sheet risk  which  were in the normal  course of
business to reduce its  exposure to  fluctuations  in the price of crude oil and
natural gas. Those instruments  involve, to varying degrees,  elements of market
and credit risk in excess of the amount  recognized  in the balance  sheets.  As
calculated  as of February 5, 1996,  the Company had 1996  natural gas and crude
oil swaps with a notional value of  approximately  $3,808,000 and a market value
of approximately  $3,686,000.  The market value changes  constantly and over the
term of the contracts  could result in a gain for the Company.  Should the price
of crude oil and natural  gas  futures be above the swap price each month,  then
the Company  would be exposed to losses but has capped that exposure in the case
of crude oil.

     Recently,  Columbus  entered into an additional swap of crude oil prices by
selling a strip of 10,000  barrels  per month for the twelve  month  period from
November,  1996 through  October,  1997 at an average  daily price of $21.17 per
barrel.  Also,  Columbus  entered  into a swap of natural  gas prices by selling
60,000  Mmbtu per month for the period from March 1997  through  October 1997 at
$2.20 per Mmbtu.

     As calculated as of January 3, 1997,  the Company had natural gas and crude
oil swaps subsequent to August 31, 1996 as follows:

                            Notional      Market or Settled

     Beginning November 1, 1994,  Resources entered into a twelve month firm gas
sales  agreement  which  required  it to deliver 2.5 Mmcf per day of natural gas
from the  Carbon  plant  to a  pipeline  company.  Based  upon the  terms of the
agreement, the average price for the term averaged CDN$1.73 per Mcf. The Company
recognized  revenue each month as  production  was sold based upon the fixed and
variable prices received until the February divestiture of Resources.

(10) LITIGATION

     On April 21, 1993,  Columbus was served with a complaint and discovery in a
lawsuit styled Michael Mattalino, Bruce L. Davis, and Maris E. Penn vs. Columbus
Energy Corp., Case No. H-93-1083,  in the United States District Court, Southern
District of Texas. The plaintiffs  alleged that in June 1987 Columbus had agreed
to assign to them  overrides in "all leases  acquired and wells  drilled" in the
original Ulrich Field Extension  Prospect acreage,  which prospect area included
only a portion  of the  Sralla  Road field near  Houston,  Texas.  They  further
asserted  that they were  entitled to overrides  under any acreage that Columbus
might acquire within an originally  agreed upon working  interest Area of Mutual
Interest ("AMI") covering almost 70 square miles and that Columbus had failed to
assign to them these additional overrides under additional acquired acreage. The
plaintiffs  prayer was for  specific  performance,  an  accounting  and punitive
damages.  Columbus  denied their  allegations and claimed they had been assigned
all overrides to which they were entitled  under the prospect.  A second lawsuit
was filed by Mattalino,  et al in the summer of 1994 which was also dismissed by
a settlement  agreement  executed in September  1994.  Provisions  of settlement
required  Columbus  to pay  $450,000  to the  plaintiffs  and  assign  them a 3%
overriding  royalty interest  ("ORRI")  effective  October 1, 1994 under certain
leases on which  there were gas wells  which had not been  previously  assigned.
Columbus is to withhold 50% of all revenues  generated by those newly created 3%
ORRI  interests  until it has recouped  $300,000  (which is  considered to be an
advance ORRI  payment) of the  $450,000.  The  settlement  costs and  recoupment
amounts have been and are being shared  proportionately  with the other  working
interest  owners in the  properties.  Columbus'  share of the entire  settlement
amount was $227,618  with the  non-recoverable  portion being  $75,873.  It also
reserved an amount of $100,000 for possible  future  non-recovery  plus interest
for its portion of the advance as a litigation expense.

     In February  1994,  (as further  amended June 1994), a lawsuit was filed in
State District Court in Webb County,  Texas styled Rancho Blanco  Corporation v.
Columbus  Energy  Corporation,  et al,  Case No.  C-94-99154,  which  sought and
obtained  a  temporary  injunction  to stop the  Zachry  No. 26 well from  being
produced from the Lobo No. 1 formation.  Rancho Blanco Corp.  ("RBC") was both a
non-consenting 50% working interest owner and a 100% royalty owner in this well.
RBC  claimed  the  hole was  sidetracked  into  the  same  reservoir  in which a
jointly-owned  well was  already  producing  which  constituted  a breach of the
operating agreement  contract.  It sought damages as well as removal of Columbus
as operator for this breach.  Columbus'  working  interest was only 0.44% in the
Zachry  #26 but it did serve as  operator  of and owned an  interest  in several
other wells on the Zachry Ranch.

     During  September  1994,  RBC and  Columbus  and all of the  other  working
interest  owner  defendants  entered  into  mediation  proceedings  which led to
settlement  of all disputes  between the parties.  Columbus  agreed to resign as
operator  of the nine wells which it operated on the ranch for which it received
$50,000  compensation.  The  Zachry 26 well  would be  allowed  to  produce  and
defendants  assigned a 10% working interest in the well free of cost to RBC plus
$10,000 and agreed to assign RBC a $50,000  production payment out of production
from any new wells drilled using  Zachry's 3-D seismic  payable out of a 15% net
revenue  interest.  These amounts are  insignificant  to Columbus' 0.44% working
interest.

     On October 14, 1993,  Columbus was served with a complaint and discovery in
a  lawsuit  styled  Porter  Farrell  II vs.  Columbus  Energy  Corp.,  Cause No.
H-93-3153,  in the United States District Court,  Southern District of Texas. By
second amended petition served on or about January 20, 1994, Porter Farrell,  II
added a failure  to  develop  claim of an area of mutual  interest  to his first
claims.  Farrell added yet a second lawsuit on September 26, 1994 assigned Cause
No. H-94-3303 but both cases were consolidated  under the first cause number for
purposes  of  discovery  and  trial.  The case had been  scheduled  for  Federal
District  Court in Houston in May, 1995 but on April 12, 1995  Columbus'  motion
for summary judgment was granted and the lawsuit was dismissed.  Subsequently on
May 10,  1995 the  plaintiff  filed a Notice of Appeal  of this  finding  by the
Federal  District  Court Judge to the United States Court of Appeals for the 5th
Circuit of New Orleans. On January 4, 1996 the plaintiff withdrew the appeal and
on January 10, 1996 an Entry of Dismissal was issued.

(11) DEFINED CONTRIBUTION PENSION PLAN

     The Company has a qualified defined  contribution  401(k) plan covering all
employees.  The Company matches, at its discretion, a portion of a participant's
voluntary  contribution  up to a certain  maximum  amount  of the  participant's
compensation.  The Company's  contribution  expense was approximately  $101,000,
$77,000,  and $58,000 in the fiscal years 1995, 1994 and 1993,  respectively and
$75,000  and  $87,000  for the nine  months  ended  August  31,  1996 and  1995,
respectively.

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS - (continued)
               (Information with respect to the nine months ended
                     August 31, 1996 and 1995 is unaudited)

     Columbus as operator of jointly owned oil and gas properties, sells oil and
gas production to relatively large U.S. oil and gas purchasers (see Note 3), and
pays  vendors  for  oil  and  gas  services.  The  risk  of  non-payment  by the
purchasers,  counter parties to the crude oil and natural gas swap agreements or
joint owners is considered minimal.  The Company does not obtain collateral from
its oil and gas purchasers for sales to them.  Joint  interest  receivables  are
subject to collection under the terms of operating agreements which provide lien
rights to the operator.

                           GLOSSARY OF INDUSTRY TERMS

     "AMI" is an area of mutual interest.

     "Bbl" is a barrel of 42 U.S.  gallons  and  represents  the basic  unit for
measuring the production of oil and condensate.

     "BOE" is barrels of oil equivalent  resulting when natural gas is converted
to oil on the  basis of its  equivalent  heating  value of six Mcf of gas to one
barrel of oil and NGL is  converted  to oil on the basis of one barrel of NGL to
one barrel of oil.

     "Btu" (British  Thermal Unit) is the quantity of heat required to raise the
temperature of one pound of water one degree Fahrenheit.

     "Developed Acreage" is acreage spaced or assignable to Productive Wells.

     "Development Drilling" is the drilling within the proved area of an oil and
gas reservoir to the depth of a stratigraphic horizon known to be productive.

     "Development  Well" is a well  drilled  within the proved area of an oil or
gas reservoir to the depth of a stratigraphic horizon known to be productive.

     "Exploratory  Well" is a well  drilled to find and produce oil or gas in an
unproved  area,  to find a new  reservoir  in a  field  previously  found  to be
productive of oil and gas in another reservoir, or to extend a known reservoir.

     "Farmout"  is a  transaction  in which the  owner of the  lease or  Working
Interest  agrees to assign an  interest  in  certain  specified  acreage  to the
assignee,  retaining some interest,  such as an overriding royalty interest,  an
oil and gas payment  offset  acreage or other type of  interest,  subject to the
drilling of one or more specified  wells or other  performance as a condition of
the assignment.

     "Gross  Acre(s)  or Gross  Well(s)"  is an  acre(s)  or  well(s) in which a
Working  Interest is owned  without  regard as to whether that  interest is less
than 100%.

     "MBbl" is a thousand  barrels,  a unit for  measuring  oil and  natural gas

                                       A-1
<PAGE>

     "Mmcf" is one million cubic feet of natural gas.

     "Net  Acre or Net  Well"  is  deemed  to exist  when the sum of  fractional
ownership  Working Interests in Gross Acres or Gross Wells equal one. The number
of Net Acres or Net Wells is the sum of the fractional  Working  Interests owned
in Gross Acres or Gross Wells expressed as whole numbers and fractions thereof.

     "NGL" is natural gas liquids,  including  condensate,  propane,  butane and
pentanes plus.

     "Net Lease Level Cash Flow " is revenue generated from Proved Reserves less
all taxes associated with production and lease operating expenses.

     "Productive"  wells  include all wells which are capable of  production  in
commercial  quantities,  including  wells  which have been  drilled to depth and
determined to be capable of such production upon completion and shut-in wells.

     "Proved  Acreage" is the part of a property to which Proved  Reserves  have
been specifically attributed.

     "Proved  Developed  Non-Producing  Reserves" are Proved Developed  Reserves
which exist  behind the casing of existing  wells,  or at minor depths below the
present  bottom of such wells,  which are expected to be produced  through these
wells in the  predictable  future,  where the  costs of making  such oil and gas
available for  production  should be relatively  small compared to the cost of a
new well.

     "Proved Developed  Producing  Reserves" are Proved Developed Reserves which
are expected to be produced from  existing  completion  intervals)  now open for
production in existing wells with existing equipment and operating methods.

     "Proved Developed  Reserves" are Proved Reserves that can be expected to be
recovered through existing wells with existing  equipment and operating methods.
Additional oil and gas expected to be obtained  through the application of fluid
injection or other improved  recovery  techniques for  supplementing the natural
forces and  mechanisms  of primary  recovery are  included as "Proved  Developed
Reserves"  only after  testing by a pilot  project or after the  operation of an
installed  program has confirmed  through  production  response  that  increased
recovery will be achieved.

     "Proved Reserves" are those estimated  quantities of crude oil, natural gas
and natural gas liquids which  geological and engineering  data demonstrate with
reasonable  certainty to be  recoverable  in future years from known  reservoirs
under existing economic and operating  conditions,  i.e., prices and costs as of
the date the  estimate  is made.  Prices  include  consideration  of  changes in
existing prices provided only by contractual  arrangements,  but not escalations
based upon future conditions.

                                       A-2

     Reservoirs are considered proved if economic  producibility is supported by
either actual production or conclusive  formation tests. The area of a reservoir
considered  proved includes (a) that portion  delineated by drilling and defined
by gas-oil and/or oil-water contacts,  if any, and (b) the immediately adjoining
portions not yet drilled,  but which can be  reasonably  judged as  economically
productive on the basis of available  geological  and  engineering  data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

     Reserves that can be produced  economically through application of improved
recovery  techniques  (such as fluid  injection)  are  included in the  "proved"
classification  when successful testing by a pilot project,  or the operation of
an installed  program in the  reservoir,  provides  support for the  engineering
analysis on which the project or program was based.

     Estimates of Proved Reserves do not include the following: (a) oil that may
become  available  from  known  reservoirs  but  is  classified   separately  as
"indicated  additional  reserves";  (b) crude oil,  natural  gas and natural gas
liquids,  the  recovery  of which is  subject  to  reasonable  doubt  because of
uncertainty as to geology,  reservoir  characteristics or economic factors;  (c)
crude oil,  natural  gas and natural  gas  liquids  that may occur in  undrilled
prospects;  and (d) crude oil,  natural gas and natural gas liquids  that may be
recovered from oil shales, coal, gilsonite and other such sources.

     "Proved  Undeveloped  Reserves" are Proved Reserves that are expected to be
recovered  from new wells drilled to known  reservoirs on undrilled  acreage for
which the existence of  recoverability  of such  Reserves can be estimated  with
reasonable   certainty,   or  from  existing  wells  where  a  relatively  major
expenditure is required to establish  production.  Reserves on undrilled acreage
are limited to those  drilling units that offset  productive  units and that are
reasonably certain of production when drilled.

     "Reserves" are that portion of the identified resources from which a usable
mineral and energy  commodity can be economically  and legally  extracted at the
time of determination.

     "Take or Pay" is a requirement  that the gas purchaser  take, or failing to
take,   pay  for  the  minimum   annual   contract   volume  of  gas  which  the
producer-seller  has  available  for  delivery.  Under such clause the purchaser
usually has the right to take the gas paid for (but  undelivered)  in succeeding
years.

     "Undeveloped  Acreage"  are those  lease acres on which wells have not been
drilled or completed to a point that would permit the  production  of commercial
quantities of oil and gas,  regardless of whether such acreage  contains  Proved
Reserves.

     "Working  interest" is an operating interest in an oil and gas leasehold or
mineral  estate,  the owner of which has the right to share in production of any
hydrocarbons  covered by the leasehold or mineral estate and has a proportionate
interest in any well  located on the land  covered by the  leasehold  or mineral
estate  and all  equipment  located  there  or used  exclusively  in  connection
therewith,  subject  to the  payment of a  proportionate  share of all costs and
expenses to be paid by the lessee in connection with development of any wells or
with exploration for oil and gas on the leasehold or mineral estate.

                     SERIES A 7% CONVERTIBLE PREFERRED STOCK


                      Pursuant to Section 7-106-102 of the
                        Colorado Business Corporation Act


First:

     The name of the Company is Columbus Energy Corp.

Second:

     Columbus Energy Corp., a Colorado corporation (the "Company"),  through the
undersigned, the President and the Secretary,  respectively, hereby certify that
pursuant to  authority  granted to and vested in the Board of  Directors  of the
Company (the "Board") by the provisions of the Articles of  Incorporation of the
Company,  the  Board  duly  adopted,  as of  October  24,  1996,  the  following
resolutions, which resolutions are still in full force and effect and are not in
conflict with any of the provisions of the Company's  Articles of Incorporation,
as amended,  or the Company's  bylaws,  as amended,  designating a series of the
Preferred Stock of the Company:

     1. Designation and Number.

     A series of Preferred Stock is hereby established and designated the Series
A 7% Convertible  Preferred  Stock (the "Series A Preferred  Stock").  Shares of
Series A Preferred  Stock are  sometimes  herein  referred to as  "Shares."  The
number of shares which constitute the Series A Preferred Stock is 2,000,000, and
each share will have a face value of $25.00 (the "Face Value").

     2. Dividends.

     (a) The holders of shares of the Series A Preferred  Stock are  entitled to
receive,  when, as and if declared by the Board out of the assets of the Company
legally available for the payment of dividends, cumulative dividends at the rate
of 7% of the face  value  ($1.75  per  share  per  year),  and no more,  payable
semi-annually  on the  fifteenth  day of March and  September  in each year (the
"Dividend  Payment  Date(s)").  Such dividends are  cumulative  from the date of
original issue of the Series A Preferred Stock (the "Issue Date").

     (b) Any dividends  declared on the Series A Preferred Stock will be paid to
holders of record of shares of the Series A  Preferred  Stock as they  appear on
the  stock  register  of the  Company  or its  agent as of a  record  date to be
selected  by the  Board,  but in any event not to exceed 45 days  preceding  the
Dividend Payment Date (the "Record Date").

                                       B-1
<PAGE>

     (c) For purposes of determining the amount of dividends "accrued" (i) as of
the  first  Dividend  Payment  Date  and as of any date  that is not a  Dividend
Payment Date,  such amount will be calculated on the basis of the rate per annum
specified  above for actual days elapsed from the Issue Date (in the case of the
first  Dividend  Payment Date and any date prior to the first  Dividend  Payment
Date) or the last  preceding  Dividend  Payment  Date (in the case of any  other
date), to but excluding the date as of which such  determination  is being made,
based on a 365-day year.

     (d)  Dividends  on the shares of Series A Preferred  Stock will accrue on a
daily  basis  (without  interest  or  compounding)  whether  or  not  there  are
unrestricted  funds  legally  available  for the payment of such  dividends  and
whether or not such dividends are declared. No interest, or sum of money in lieu
of interest,  will be payable in respect of any dividend  payment or payments on
the Series A  Preferred  Stock that may be in arrears.  Dividends  will cease to
accrue in  respect  of shares of Series A  Preferred  Stock on the date of their
redemption or conversion.

     (e) Accrued and unpaid dividends for any past Dividend Period (that is, the
period  beginning  after  any  Dividend  Payment  Date  and  ending  on the next
succeeding  Dividend  Payment Date) or Dividend Periods may be declared and paid
at any time, without reference to any Dividend Payment Date to holders of record
on  such  date,  not  exceeding  45  days  preceding  the  payment  date of such
dividends, as may be fixed by the Board.

     (f) Any  dividend  payment  made on the shares of Series A Preferred  Stock
will first be credited against the earliest accrued but unpaid dividend due with
respect to the shares of Series A Preferred Stock.

     (g) All  dividends  paid with  respect to the shares of Series A  Preferred
Stock will be paid pro rata to the holders entitled to such dividends.

     3. Optional Redemption by the Company.

     (a) The Series A Preferred Stock is redeemable, in whole or in part, at the
election of the Company, at any time after _________________,  199__ (six months
after the Issue Date) as follows:

After November 30, 2005:                         Face Value

If fewer than all of the Series A Preferred  Stock are to be redeemed,  then the
shares of Series A Preferred  Stock to be redeemed will be chosen by the Company
pro rata (as nearly as may be  practicable)  among all  holders  of  outstanding
shares of Series A  Preferred  Stock.  If  shares  of Series A  Preferred  Stock
evidenced  by a  certificate  selected  for partial  redemption  are  thereafter
converted in part  pursuant to  paragraph 6, the shares so converted  (as far as
may be practicable) will be deemed to be the shares selected for redemption. The
Company  will not be required to register a transfer of (i) any shares of Series
A Preferred  Stock within five  business  days next  preceding  any selection of
shares of Series A Preferred Stock to be redeemed,  or (ii) any shares of Series
A Preferred Stock called for redemption.

     (b) The Company will provide notice of any redemption of shares of Series A
Preferred  Stock to holders of record of Series A Preferred  Stock not less than
30 nor more  than 60 days  prior to the date  fixed  for such  redemption.  Such
notice (a  "Redemption  Notice")  will be  provided  by  mailing  notice of such
redemption first class,  postage prepaid,  to each holder of record of shares of
Series A Preferred  Stock,  at such holder's  address as it appears on the stock
register of the  Company,  except that neither a failure to give such notice nor
any defect in such  notice will affect the  validity of the  proceeding  for the
redemption of any shares of Series A Preferred Stock to be redeemed except as to
the holders to whom the  Company has failed to give such notice or whose  notice
was defective.  In addition to any information required by law or the applicable
rules of the American Stock Exchange or any other national  securities  exchange
on which the shares of Series A  Preferred  Stock are  listed,  each  Redemption
Notice will state,  as  appropriate,  the following  (and may contain such other
information as the Company deems advisable):

          (i) the date specified for redemption of the Series A Preferred  Stock
     (the "Redemption Date ");

          (ii) that all outstanding shares of Series A Preferred Stock are to be
     redeemed  or,  in the  case of a call  for  redemption  of  fewer  than all
     outstanding  shares of Series A Preferred  Stock, the number of shares held
     by such holder to be redeemed;

          (iii) the applicable redemption price specified in paragraph 3(a) (the
     "Redemption Price");

                                       B-3
<PAGE>

          (iv) the place or places  where  certificates  for Series A  Preferred
     Stock to be redeemed are to be surrendered for redemption;

          (v) that  dividends  on the shares of Series A  Preferred  Stock to be
     redeemed will cease to accrue on the  Redemption  Date (except as otherwise
     provided in this Certificate of Designation); and

          (vi) the then current Conversion Rate (as defined below) and the place
     or  places  where   certificates  for  Series  A  Preferred  Stock  may  be
     surrendered for conversion  pursuant to paragraph 6, and will further state
     that the conversion privilege will terminate immediately prior to the close
     of business on the tenth day preceding the Redemption Date.

     (c) If the  Redemption  Notice with respect to shares of Series A Preferred
Stock to be redeemed  pursuant to this  paragraph  has been timely  given by the
Company,  and if, on or before the applicable  Redemption  Date, the Company has
set apart so as to be available  for such  purpose and only such  purpose  funds
sufficient  to pay in full the  aggregate  Redemption  Price for such  shares of
Series A Preferred Stock on such Redemption Date, then effective as of the close
of business on such  Redemption  Date,  such shares of Series A Preferred  Stock
will no longer be deemed outstanding  (notwithstanding  that any certificate for
such shares has not been surrendered for  cancellation),  dividends with respect
to the shares so called for  redemption  will cease to accrue on the  Redemption
Date (provided  that holders of shares of Series A Preferred  Stock at the close
of business on a Record  Date for any payment of  dividends  will be entitled to
receive  the  dividend  payable  on such  shares on the  corresponding  Dividend
Payment Date notwithstanding the redemption of such shares following such Record
Date and prior to such Dividend  Payment  Date),  and all rights with respect to
the shares so called for redemption will  immediately  after such date cease and
terminate,  except the right of such holders, upon the surrender of certificates
evidencing  the  shares of Series A  Preferred  Stock so  redeemed,  to  receive
payment in cash in the amount of the Redemption Price for such shares. Any funds
so set apart which remain  unclaimed at the end of one year after the Redemption
Date will be released to the Company,  after which time the holders of shares of
Series A Preferred  Stock called for  redemption  on such  Redemption  Date that
remain  outstanding after such one-year period will look only to the Company for
the payment of the Redemption Price for such shares, without interest, unless an
applicable escheat or abandoned property law otherwise  requires.  If any shares
of Series A Preferred  Stock so called for redemption are converted  pursuant to
paragraph 6, between the date such funds are set apart and the close of business
on the Redemption  Date,  then the funds so set apart for the redemption of such
shares so converted will be promptly released to the Company.

                                       B-4
<PAGE>

     (d) At its election, the Company on or prior to any Redemption Date (but no
more  than 90 days  prior  to such  Redemption  Date)  may  deposit  immediately
available funds  sufficient to pay the aggregate  Redemption Price of the shares
of Series A Preferred  Stock called for redemption on such date in trust for its
holders with any bank or trust  company  organized  under the laws of the United
States of America or any of its states  having  capital,  undivided  profits and
surplus  aggregating  at  least  $50  million  (the  "Redemption  Agent"),  with
irrevocable instructions and authority to the Redemption Agent, on behalf and at
the expense of the Company, to mail the Redemption Notice as soon as practicable
after  receipt of such  irrevocable  instructions  (or to complete  such mailing
previously  commenced,  if it has not already been completed) and to pay, on and
after  such  Redemption  Date,  the  Redemption  Price of the shares of Series A
Preferred Stock to be redeemed to their respective holders upon the surrender of
their certificates.  A deposit made in compliance with the immediately preceding
sentence  shall be deemed to constitute  full payment for the shares of Series A
Preferred  Stock to be  redeemed  and from and  after  the later of the close of
business on the date of such deposit (although prior to such Redemption Date) or
the date the Redemption Notice is mailed, the shares of Series A Preferred Stock
to be redeemed shall no longer be deemed outstanding and the holders of Series A
Preferred Stock shall cease to be  stockholders  with respect to such shares and
will have no rights  with  respect  to such  shares  except (x) the right of the
holders of Series A Preferred  Stock to receive the  Redemption  Price,  without
interest,  for shares of Series A Preferred  Stock to be redeemed upon surrender
of their  certificates  and (y) the right to convert  such shares in  accordance
with  paragraph  6 prior to the close of business on the tenth day prior to such
Redemption Date. Any interest accrued on funds so deposited shall be paid by the
Redemption  Agent to the Company from time to time. Any funds deposited with the
Redemption  Agent  which  remain  unclaimed  at the end of one  year  after  the
Redemption Date shall be returned by the Redemption Agent to the Company,  after
which  return  the  holders  of shares of Class A  Preferred  Stock  called  for
redemption on such Redemption Date that remain  outstanding  after such one-year
period  shall look only to the Company for the payment of the  Redemption  Price
for such shares,  without  interest,  unless an applicable  escheat or abandoned
property  law  otherwise  requires.  If any shares of Series A  Preferred  Stock
called for redemption on such Redemption Date are converted,  in accordance with
paragraph 6, between the date such funds are so  deposited  with the  Redemption
Agent and the close of business on the tenth day prior to the  Redemption  Date,
then  the  funds  (including  cash  for any  adjustment  in  lieu of  delivering
fractional  shares) so deposited for the  redemption of such shares so converted
shall be promptly returned by the Redemption Agent to the Company.

     (e) Each holder of shares of Series A Preferred  Stock to be redeemed  will
surrender the certificates evidencing such shares (properly endorsed or assigned
to the  Company  in blank and with  signatures  guaranteed,  if the  Company  so
requires  and the  Redemption  Notice so  states)  to the  Company  at the place
designated  in the  Redemption  Notice  for such  redemption  and will upon such
surrender be entitled to receive the  consideration for such shares specified in
the Redemption  Notice in an aggregate  amount equal to the Redemption Price for
such  shares.  If fewer  than all of the  shares  of  Series A  Preferred  Stock
represented by any such surrendered certificate are called for redemption, a new
certificate  will be issued  at the  expense  of the  Company  representing  the
unredeemed shares.

     4. Mandatory Redemption by the Company.

     (a) The issued and outstanding Series A Preferred Stock will be redeemed at
the then  applicable  Redemption  Price,  (i)  within 60 days  after a Change in
Control  (as defined  below) has  occurred,  if the Board has not by  resolution
given its approval of the Change in Control  prior to its  occurrence,  and (ii)
within two years  after a Change in Control  has  occurred,  if the Board has by
resolution  given its approval of the Change in Control prior to its  occurrence
(in either such case,  a  "Mandatory  Redemption  Date").  The Board will Give a
Redemption  Notice to all holders of the Series A Preferred Stock within 15 days
after it learns  that a Change in Control  has  occurred.  A "Change in Control"
means that any Person (as defined below), other than Harry A. Trueblood, Jr., or
his estate or heirs,  together with such Person's Affiliates (as defined below),
controls,  by direct or beneficial  ownership (or both),  over 50% of the voting
power of the  capital  stock  necessary  to elect a  majority  of the  Board.  A
"Person"  means  an  individual,  corporation,  partnership,  limited  liability
company, trust or other entity of any nature.  "Affiliate" has the meaning given
to such term in Rule 144 of the Securities and Exchange  Commission  promulgated
under the Securities Act of 1933.

     (b) The Company will redeem on the Mandatory  Redemption Date all shares of
Series A Preferred Stock remaining outstanding at the Redemption Price. If funds
of the  Company  legally  available  for  redemption  of shares of the  Series A
Preferred Stock are  insufficient to redeem the total number of shares of Series
A Preferred Stock remaining outstanding, those funds which are legally available
will be used to  redeem  the  maximum  possible  number  of  shares  of Series A
Preferred  Stock.  At any time and from time to time  thereafter when additional
funds of the Company are legally  available  for such  purpose,  such funds will
immediately be used to redeem the shares of Series A Preferred  Stock which were
required to be redeemed  that the Company  failed to redeem until the balance of
such shares has been redeemed.  The selection of shares to be redeemed  pursuant
to  the  two  immediately  preceding  sentences  will  be  made,  as  nearly  as
practicable, on a pro rata basis as among the different classes or series and as
among the holders of shares of a particular class or series.

     (c) Each holder of shares of Series A Preferred  Stock to be redeemed  will
surrender the certificates evidencing such shares (properly endorsed or assigned
to the  Company  in blank and with  signatures  guaranteed,  if the  Company  so
requires  and the  Redemption  Notice so  states)  to the  Company  at the place
designated  in the  Redemption  Notice  for such  redemption  and will upon such
surrender be entitled to receive the  consideration for such shares specified in
the Redemption  Notice in an aggregate  amount equal to the Redemption Price for
such shares.

     5. Limitations on Dividends and Redemptions.

     (a) As long as any shares of Series A Preferred Stock are  outstanding,  no
dividends  will be paid or declared  in cash or  otherwise  on Junior  Stock (as
defined  below),  nor will any other  distribution  be made on any Junior Stock,
unless (i) all accrued dividends on the Series A Preferred Stock have been paid,
or declared and set aside for payment,  for all dividend periods  terminating on
or prior to the date of such Junior Stock dividend or  distribution  payment and
(ii) the  Company  is not in  default  on any of its  obligations  to redeem any
Series A Preferred  Stock.  "Junior  Stock" means each class or series of common
stock of the  Company,  and any other  class or series of  capital  stock of the
Company  to be  created  to the  extent  that it ranks  junior  to the  Series A
Preferred  Stock as to  dividend  rights,  rights  of  redemption  or  rights on
liquidation, as the case may be.

                                       B-6
<PAGE>

     (b) As long as any shares of Series A Preferred Stock are  outstanding,  no
shares of any Junior Stock may be purchased,  redeemed, or otherwise acquired by
the  Company,  and no funds may be set aside or made  available  for any sinking
fund for the  purchase,  redemption  or other  acquisition  of any Junior Stock,
unless all accrued  dividends on all Series A Preferred Stock have been paid, or
declared and set aside for payment for all dividend  periods  terminating  on or
prior to the date of such purchase,  redemption or acquisition,  and the Company
is not in default  on any of its  obligations  to redeem any Series A  Preferred
Stock.

     (c) Subject to the provisions of subparagraphs (a) and (b) above, dividends
or distributions may be declared and paid on the shares of any from time to time
and any Junior Stock may be  purchased,  redeemed or  otherwise  acquired by the
Company from time to time.  In the event of the  declaration  and payment of any
such  dividends  or  distributions,  the  holders of such  Junior  Stock will be
entitled,  to the exclusion of holders of shares of Series A Preferred Stock, to
share  in  such  dividends  and  distributions  according  to  their  respective
interests.

     (d) Nothing  contained  in this  paragraph  will prevent (i) the payment of
dividends or the making of distributions on any Junior Stock solely in shares of
Junior Stock (together with a cash adjustment for fractional shares, if any), or
the redemption, purchase or other acquisition of Junior Stock solely in exchange
for (together with a cash adjustment for fractional  shares, if any), or through
the application of the proceeds from the sale of, shares of Junior Stock, or the
conversion of Series A Preferred Stock for shares of common stock of the Company
(together with a cash adjustment for fractional  shares, if any) pursuant to the
provisions of paragraph 6.

     (e) The provisions of  subparagraphs  (a) and (b) of this paragraph are for
the sole benefit of the holders of the Series A Preferred Stock and accordingly,
at any time when the holders of shares of Series A  Preferred  Stock have waived
(as provided in paragraph 16) in whole or in part the benefit of the  provisions
of subparagraphs (a) and (b) (either generally or in the specific instance), and
(ii) the holders of shares of Series A Preferred  Stock have waived (as provided
in paragraph  16) in whole or in part the benefit of the  provisions of (a), (b)
or (d) (either generally or in the specific instance), then such provisions will
not (to the extent  waived,  in the case of any  partial  waiver)  restrict  the
payment of  dividends  or the  making of  distributions  on, or the  redemption,
purchase or other  acquisition of any shares of, Series A Preferred Stock or any
Junior Stock.

     6. Conversion at Option of Holder.

     (a) Subject to the  provisions  of this  paragraph,  each share of Series A
Preferred  Stock is  convertible,  in whole or from time to time in part, at the
option  of the  holder,  at any time from and after the 60th day after the Issue
Date and prior to the close of business on the tenth day prior to any Redemption
Date, unless previously redeemed, at the rate of [____________] shares of common
stock,  $.20 par value, of the Company ("Common Stock") for each Share converted
(the "Conversion Rate"). The right to convert shares of Series A Preferred Stock
called for redemption will terminate  immediately prior to the close of business
on the tenth day prior to the related Redemption Date.

                                       B-7
<PAGE>

     (b) In order to convert shares of Series A Preferred Stock, the holder must
surrender the certificates  evidencing the shares of Series A Preferred Stock to
be converted at the principal office of the Company or its agent,  duly endorsed
to the  Company or in blank (or  accompanied  by duly  executed  instruments  of
transfer  to  the  Company  or  in  blank)  with  signatures   guaranteed  (such
endorsements  or  instruments  of  transfer  to be in form  satisfactory  to the
Company),  together with written  notice of conversion  specifying the number of
shares of Series A Preferred  Stock to be converted and  specifying  the name or
names (with addresses) in which the certificate or certificates representing the
Common Stock deliverable on such conversion are to be registered,  and otherwise
in accordance with conversion procedures established by the Company. Each notice
of conversion  will be  irrevocable,  and each conversion will be deemed to have
been  effected  immediately  prior to the  close of  business  on the date  (the
"Conversion  Date") on which all of the  requirements  for such conversions have
been  satisfied.  If any transfer is involved in the issuance or delivery of any
certificate or certificates for shares of Common Stock in a name other than that
of the registered  holder of the shares of Series A Preferred Stock  surrendered
for conversion, such holder will also deliver to the Company a sum sufficient to
pay  all  taxes,  if any,  payable  in  respect  of such  transfer  or  evidence
satisfactory  to the Company that such taxes have been paid.  Except as provided
in the immediately preceding sentence,  the Company will pay any issue, stamp or
other similar tax in respect of such issuance or delivery.

     (c) As promptly as practicable  after the Conversion Date, the Company,  in
accordance with the provisions of this paragraph, will issue and deliver at said
office or agency to the  holder  of the  shares of Series A  Preferred  Stock so
surrendered  for  conversion,  or on his or her written  order, a certificate or
certificates  for the  number  of full  shares  of Common  Stock  issuable  upon
conversion of such shares in accordance  with the provisions of this  paragraph,
and any fractional interest will be settled in accordance with paragraph 10.

     (d) The person in whose name the  certificate for shares of Common Stock is
issued upon such  conversion will be treated for all purposes as the stockholder
of record of such  shares of  Common  Stock as of the close of  business  on the
Conversion  Date;  provided,  however,  that no  surrender of Series A Preferred
Stock on any date when the stock  transfer  books of the  Company are closed for
any purpose will be effective to  constitute  the person or persons  entitled to
received  the shares of Common Stock  deliverable  upon such  conversion  as the
record  holder(s)  of such  shares of Series A Common  Stock on such  date,  but
surrender  will be  effective  (assuming  all other  requirements  for the valid
conversion  of such shares have been  satisfied)  to  constitute  such person or
persons as the record  holder(s) of such shares of Common Stock for all purposes
as of the  opening of business  on the next  succeeding  day on which such stock
transfer books are open. Upon conversion of shares of Series A Preferred  Stock,
the rights of the holder of such shares, as a holder of such shares, will cease.

                                       B-8
<PAGE>

     (e) Holders of shares of Series A Preferred  Stock at the close of business
on a Record  Date for any  payment of  declared  dividends  will be  entitled to
receive  the  dividend  payable  on such  shares on the  corresponding  Dividend
Payment Date  notwithstanding the effective  conversion of such shares following
such Record Date and prior to the corresponding  Dividend Payment Date. However,
shares of Series A Preferred Stock surrendered for conversion after the close of
business on a Record Date for any payment of dividends and before the opening of
business on the next  succeeding  Dividend  Payment Date must be  accompanied by
payment in cash of an amount equal to the dividend  thereon  attributable to the
current  Dividend  Period  which  is to be paid on such  Dividend  Payment  Date
(unless such shares are subject to redemption on a Redemption  Date between such
Record  Date and such  Dividend  Payment  Date).  A holder of shares of Series A
Preferred Stock called for redemption on any Dividend Payment Date will (if such
holder is the  registered  holder on the  applicable  Record  Date)  receive the
dividend  on such shares  payable on that date and will be able to convert  such
shares after the Record Date for such dividend without paying an amount equal to
such dividend to the Company upon conversion. Except as provided above, upon any
conversion of shares of Series A Preferred Stock pursuant to this paragraph, the
Company will make no payment or allowance for unpaid  dividends,  whether or not
in arrears,  on  converted  shares of Series A Preferred  Stock and will make no
payment or allowance for previously  declared  dividends or distributions on the
shares of Common Stock issued upon such conversion.

     (f) If the shares of Series A Preferred Stock  represented by a certificate
surrendered for conversion are converted in part only, the Company will cause to
be  issued  and  delivered  to the  registered  holder,  without  charge,  a new
certificate or certificates representing the aggregate the number of unconverted
shares.

     7. Conversion Rate Adjustments.

     (a) If the  Company  at any  time or from  time to  time,  (1)  declares  a
dividend on the Common Stock payable in shares of its capital  stock  (including
Common Stock),  (2) subdivides the  outstanding  Common Stock,  (3) combines the
outstanding  Common  Stock into a smaller  number of  shares,  or (4) issues any
shares of its capital stock in a reclassification of the Common Stock (including
any such  reclassification in connection with a consolidation or merger in which
the  Company is the  surviving  Person),  then in each such case,  the number of
shares of Common  Stock into which the Series A Preferred  Stock will convert at
the time of the record date for such dividend or of the  effective  date of such
subdivision, combination or reclassification,  and the number and kind of shares
of Common Stock issuable on such dates will be proportionately adjusted so that,
in connection with a conversion of the Series A Preferred Stock after such date,
the  holder of the Series A  Preferred  Stock will be  entitled  to receive  the
aggregate  number and kind of shares of capital stock which,  if the  conversion
had occurred  immediately  prior to such date,  the holder would have owned upon
such  conversion  and would  have been  entitled  to  receive  by virtue of such
dividend, subdivision, combination or reclassification. Any such adjustment will
become  effective  immediately  after the record  date of such  dividend  or the
effective  date of  such  subdivision,  combination  or  reclassification.  Such
adjustment will be made successively  whenever any event listed above occurs. If
a dividend is declared  and such  dividend is not paid,  the number of shares of
Common  Stock into  which the Series A  Preferred  Stock  will  convert  will be
adjusted  to that  number  of shares of Common  Stock  into  which the  Series A
Preferred Stock would convert immediately prior to such record date.

                                       B-9
<PAGE>

     (b) In case this Company  shall issue any rights or warrants to all holders
of shares of Common Stock  entitling them (for a period  expiring within 45 days
after the record date for the determination of stockholders  entitled to receive
such rights or warrants) to subscribe for or purchase  shares of Common Stock or
securities   convertible  into  or  exchangeable  for  shares  of  Common  stock
("Convertible  Securities")  at a price per share of Common  Stock (or having an
initial  exercise price or conversion price per share of Common Stock) less than
the then  current  market  price  per share of Common  Stock (as  determined  in
accordance  with the  provisions of Section 7(d) below) on such record date, the
number of shares of Common  Stock  into which each  Share  shall  thereafter  be
convertible  shall be determined by  multiplying  the number of shares of Common
Stock into which such Share was  theretofore  convertible  immediately  prior to
such  record date by a fraction  of which the  numerator  shall be the number of
shares  of Common  Stock  outstanding  on such  record  date plus the  number of
additional  shares of Common Stock offered for subscription or purchase (or into
which the Convertible  Securities so offered are initially  convertible)  and of
which the denominator  shall be the number of shares of Common Stock outstanding
on such  record  date  plus the  number of  shares  of  Common  Stock  which the
aggregate  offering  price of the total  number  of  shares  of Common  Stock so
offered  (or  the  aggregate  initial   conversion  or  exercise  price  of  the
Convertible  Securities so offered)  would  purchase at the then current  market
price per share of Common Stock (as determined in accordance with the provisions
of Section  5(d)  below) on such  record  date.  Such  adjustment  shall be made
successively  whenever  any such rights or warrants  are issued and shall become
effective   immediately   after  the  record  date  for  the   determination  of
stockholders  entitled to receive such rights or warrants. In the event that all
of the shares of Common Stock (or all of the Convertible  Securities) subject to
such rights or warrants have not been issued when such rights or warrants expire
(or, in the case of rights or warrants to purchase Convertible  Securities which
have been exercised,  all of the shares of Common Stock issuable upon conversion
of such  Convertible  Securities have not been issued prior to the expiration of
the conversion  right  thereof),  then the  Conversion  Rate shall be readjusted
retroactively  to be the  Conversion  Rate which would then be in effect had the
adjustment  upon the issuance of such rights or warrants  been made on the basis
of the  actual  number of shares of  Common  Stock (or  Convertible  Securities)
issued upon the exercise of such rights or warrants (or the  conversion  of such
Convertible  Securities);  but such subsequent  adjustment  shall not affect the
number of shares of Common Stock issued upon the  conversion  of any Share prior
to the date such subsequent adjustment is made.

     (c) In case the Company shall distribute to all holders of shares of Common
Stock (including any such distribution made in connection with a merger in which
the Company is the continuing corporation,  other than a merger to which Section
7(e) is applicable)  any  securities,  evidences of its  indebtedness  or assets
(other than cash  dividends out of earnings or Capital Stock in respect of which
an  adjustment is made pursuant to Section 7(a) hereof) or rights or warrants to
purchase shares of Common Stock or securities  convertible into shares of Common
Stock  (excluding  those  referred to in Section 7(b) above),  then in each such
case the number of shares of Common Stock into which each Share shall thereafter
be convertible shall be determined by multiplying the number of shares of Common
Stock into which such Share was theretofore convertible immediately prior to the
record  date for the  determination  of  stockholders  entitled  to receive  the
distribution  by a fraction  of which the  numerator  shall be the then  current
market  price per  share of Common  Stock  (as  determined  accordance  with the
provisions  of  Section  7(d)  below)  on such  record  date  and of  which  the
denominator  shall be such  current  market price per share of Common Stock less
the  fair  market  value on such  record  date (as  determined  by the  Board of
Directors of the Corporation,  whose  determination  shall be conclusive) of the
portion of the  securities,  assets or evidences of  indebtedness  or rights and
warrants so to be  distributed  applicable  to one share of Common  Stock.  Such
adjustment shall be made successively whenever any such distribution is made and
shall become effective  immediately  after the record date for the determination
of stockholders entitled to receive such distribution.

                                      B-10
<PAGE>

     (d) The current market price per share of Common Stock at any date shall be
deemed to be the average of the daily closing prices for a share of Common Stock
for the ten  consecutive  trading days before the day in  question.  The closing
price for each day shall be the last reported sale price regular way or, in case
no such  reported  sale takes  place on such day,  the  average of the  reported
closing bid and asked prices regular way, in either case on the composite  tape,
or if the shares of Common Stock are not quoted on the  composite  tape,  on the
principal  United States  securities  exchange  registered  under the Securities
Exchange Act of 1934, as amended (the  "Exchange  Act"),  on which the shares of
Common  Stock are listed or admitted  to  trading,  or if they are not listed or
admitted to trading on any such  exchange,  the last reported sale price (or the
average of the quoted  closing  bid and asked  prices if there were no  reported
sales) as reported by the National  Association of Securities  Dealers Automated
Quotation System ("NASDAQ") or any comparable  system, or if the Common Stock is
not quoted on NASDAQ or any  comparable  system,  the average of the closing bid
and asked  prices as  furnished  by any member of the  National  Association  of
Securities  Dealers,  Inc.  selected  from time to time by the  Company for that
purpose or, in the absence of such quotations,  such other method of determining
market value as the Board of Directors shall from time to time deem to be fair.

     (e) In case of any  reclassification  or change in the Common  Stock (other
than any reclassification or change referred to in Section 7(a) and other than a
change in par value) or in case of any  consolidation  of the  Company  with any
other  corporation  or any merger of the Company into another  corporation or of
another  corporation  into the Company (other than a merger in which the Company
is the continuing  corporation and which does not result in any reclassification
or change (other than a change in par value or any reclassification or change to
which Section 7(a) is applicable) in the outstanding  Common Stock),  or in case
of any sale or transfer to another corporation or entity (other than by mortgage
or  pledge)  of all or  substantially  all of the  properties  and assets of the
Company,  the Company (or its successor in such  consolidation or merger) or the
purchaser of such properties and assets shall make appropriate provision so that
the holder of a Share shall have the right thereafter to convert such Share into
the kind and  amount of shares of stock and other  securities  and  property  (a
"Successor  Interest") that such holder would have owned  immediately after such
reclassification, change, consolidation, merger, sale or transfer if such holder
had converted  such Share into Common Stock  immediately  prior to the effective
date of such reclassification,  change, consolidation,  merger, sale or transfer
(assuming for this purpose (to the extent applicable) that such holder failed to
exercise  any rights of election and received per share of Common Stock the kind
and amount of shares of stock and other  securities  and  property  received per
share by a plurality of the non-electing  shares), and the holders of the Series
A Preferred Stock shall have no other conversion  rights under these provisions;
provided, that effective provision shall be made, in the Articles or Certificate
of  Incorporation  of the resulting or surviving  corporation or otherwise or in
any contracts of sale or transfer,  so that the  provisions set forth herein for
the  protection of the conversion  rights of the Series A Preferred  Stock shall
thereafter be made applicable,  as nearly as reasonably may be to any such other
shares of stock and other securities and property deliverable upon conversion of
the  Series  A  Preferred  Stock  remaining  outstanding  or  other  convertible
preferred  stock or other  Convertible  Securities  received  by the  holders of
Series A Preferred Stock in place thereof; and provided,  further, that any such
resulting  or surviving  corporation  or purchaser  shall  expressly  assume the
obligation  to deliver,  upon the  exercise of the  conversion  privilege,  such
shares,  securities  or property as the holders of the Series A Preferred  Stock
remaining outstanding, or other convertible preferred stock or other convertible
securities  received  by the  holders in place  thereof,  shall be  entitled  to
receive  pursuant  to the  provisions  hereof,  and to make  provisions  for the
protection of the conversion rights as above provided.

     (f) No adjustment to the Conversion Rate will be made if the amount of such
adjustment  would  result in a change in the  Conversion  Rate per share of less
than $.01, but in such case any adjustment  that would  otherwise be required to
be made will be  carried  forward  and will be made at the time of and  together
with the next  subsequent  adjustment,  which,  together with any  adjustment so
carried  forward,  would result in a change in the  Conversion  Rate of at least
$.01 per share.

     8. Notice of Adjustments.

     Whenever  the  Conversion   Rate  is  adjusted  as  provided  for  by  this
Certificate, the Company will:

     (a)  compute  the  adjusted   Conversion   Rate  in  accordance  with  this
Certificate  and  prepare a  certificate  signed by an  officer  of the  Company
setting  forth the  adjusted  Conversion  Rate,  the  method of  calculation  in
reasonable  detail and the facts  requiring such  adjustment and upon which such
adjustment is based,  which  certificate  will be conclusive,  final and binding
evidence of the correctness of the adjustment  (absent manifest error), and file
such  certificate  with the transfer  agent for the shares of Series A Preferred
Stock and the Common Stock; and

     (b) mail a notice  to the  holders  of the  outstanding  shares of Series A
Preferred  Stock stating that the Conversion  Rate has been adjusted,  the facts
requiring such  adjustment  and upon which such  adjustment is based and setting
forth the adjusted Conversion Rate,.

     9. Actions in Respect of Common Stock.

     The Company will take such reasonable action which may be necessary, in the
opinion of the Company's counsel,  in order that (a) the Company may validly and
legally  deliver  fully paid and  nonassessable  shares of Common Stock upon any
surrender of shares of Series A Preferred  Stock for  redemption  or  conversion
pursuant to paragraphs 3, 4 and 6, (b) the delivery of shares of Common Stock in
accordance with this paragraph is exempt from the  registration or qualification
requirements of the Securities Act and applicable  state  securities laws or, if
no such exemption is available,  that the offer and conversion of such shares of
Common Stock have been duly registered or qualified under the Securities Act and
applicable  state securities laws, (c) the shares of Common Stock delivered upon
such  conversion  are listed for trading on the  American  Stock  Exchange or on
another national securities exchange (upon official notice of issuance), and (d)
the shares of Common Stock delivered upon such conversion are free of preemptive
rights and any liens or adverse  claims.  The Company has agreed to at all times
reserve and keep available, free from preemptive rights, out of the aggregate of
its authorized but unissued Common Stock and its issued Common Stock held in its
treasury,  for the purpose of  effecting  any  conversion  of shares of Series A
Preferred  Stock at the option of the holder  pursuant to  paragraph 6, the full
number of shares of Common Stock  deliverable  upon the  conversion  of all then
outstanding  shares of Series A Preferred  Stock (assuming for this purpose that
all of the  outstanding  shares of Series A Preferred Stock are held by a single
holder).

     10. No Fractional Shares of Common Stock.

     No  fractional  shares of  Common  Stock or scrip  will be issued  upon the
conversion of Series A Preferred Stock for Common Stock. In lieu of the issuance
of a fraction of a share of Common Stock or scrip,  the Company will pay instead
an amount in cash (rounded to the nearest whole cent) equal to the same fraction
of the closing  price of a share of Common Stock on the trading day  immediately
preceding the Conversion Date, the Dividend Payment Date or the Redemption Date,
as the case may be.

     11. Payment of Taxes.

     The Company  will pay any and all  documentary,  stamp or similar  transfer
taxes  payable in respect of the delivery of shares of Common Stock  pursuant to
paragraph  6, but the  Company  will not be required to pay any tax which may be
payable in respect of any  registration of transfer  involved in the delivery of
shares of Common Stock upon a conversion  of shares of Series A Preferred  Stock
pursuant to  paragraph 6 in a name other than that of the  registered  holder of
such shares of Series A Preferred Stock.

     12. No Preemptive Rights.

     The holders of shares of Series A Preferred  Stock will have no  preemptive
rights,  including preemptive rights with respect to any shares of capital stock
or other  securities  of the  Company  convertible  into or  carrying  rights or
options to purchase any such shares.

     13. Voting Rights.

     (a) The holders of Series A Preferred Stock will have the right to one vote
for each share of Series A Preferred Stock held by them, and will be entitled to
notice of any  meeting of  shareholders  of the  Company and will be entitled to
vote  together  with holders of the Common Stock with respect to any matter upon
which holders of Common Stock are entitled to vote.

                                      B-13

     (b) At any  time  accrued  dividends  payable  on the  shares  of  Series A
Preferred  Stock are in arrears and unpaid in an  aggregate  amount  equal to or
exceeding the aggregate  amount of dividends  payable on such shares for four or
more Dividend Periods (whether or not consecutive)(a  "Dividend  Default"),  the
holders of the shares of Series A Preferred Stock, voting separately as a class,
will have the right to vote for the election of two  directors  (the  "Preferred
Stock  Directors") to the Board,  such directors to be in addition to the number
of directors  constituting  the Board  immediately  prior to the accrual of such
right.  Such right of the holders of shares of Series A Preferred  Stock to vote
for the election of two Preferred Stock  Directors  will, when vested,  continue
until all  dividends  in arrears on the shares of Series A Preferred  Stock have
been paid in full and, when so paid,  such right will cease,  subject  always to
the same  provisions  for the vesting of such right in the holders of the shares
of  Series A  Preferred  Stock in the case of  further  Dividend  Defaults.  The
Preferred  Stock  Directors  will be elected by a majority of the votes actually
cast by the holders of Series A Preferred Stock.

     (c) At any time when the holders of shares of the Series A Preferred  Stock
are entitled to elect two Preferred Stock Directors,  the Company will, upon the
written  request (a  "Request") of the holders of record of not less than 10% of
the outstanding  shares of Series A Preferred  Stock,  call a special meeting of
holders of the Series A Preferred  Stock for the  election of the two  Preferred
Stock Directors.  Notice of the special meeting will be given in accordance with
the requirements of Colorado law, and such meeting will be held not more that 60
days after the Company's  receipt of the Request.  The Preferred Stock Directors
will be nominated  by the persons who submit the  Request,  and will serve until
the earlier of (i) such person's  resignation or (ii) the cure by the Company of
any  Dividend  Default.  The Company will not be obligated to call more than one
special  meeting of  shareholders  for the purpose of electing  Preferred  Stock
Directors  in any twelve month period  during the  continuation  of any Dividend
Default.  No person may be nominated or may serve as a Preferred  Stock Director
unless such person meets all  requirements for serving on the Board as set forth
in any applicable law.

     (d) If,  prior  to the  end of the  term of any  Preferred  Stock  Director
elected as provided above, a vacancy in the office of such director occurs, such
vacancy  will  be  filled  for the  unexpired  term  by the  appointment  by the
remaining  Preferred  Stock Director of a new director for the unexpired term of
such former  Preferred  Stock  Director.  If both Preferred  Stock  Directors so
elected by the holders of shares of Series A Preferred  Stock cease, at the same
time, to serve as directors before their terms expire, the holders of the shares
of Series A Preferred  Stock may, at a special  meeting of the holders called as
provided in subparagraph (c) above, nominate and elect successors to hold office
for the unexpired terms of such Preferred Stock Directors.

                                      B-14
<PAGE>

     (e)  For as  long  as  any  shares  of  Series  A  Preferred  Stock  remain
outstanding,  the  affirmative  vote of the holders at least  two-thirds of such
outstanding Shares (voting  separately as a class),  given in person or by proxy
at an annual  meeting  or  special  meeting  called  for such  purpose,  will be
necessary  before  the  Company  may  (i)  amend,  alter  or  repeal  any of the
provisions  of its  Articles  of  Incorporation  so as to  adversely  affect the
powers, preferences or rights of the holders of the shares of Series A Preferred
Stock then  outstanding  or reduce the minimum  time  required for any notice to
which  holders of shares of Series A  Preferred  Stock then  outstanding  may be
entitled;  or (ii) authorize or issue any capital stock which ranks prior to, or
on a parity with, the Series A Preferred Stock as to dividend rights,  rights of
redemption  or rights of  liquidation  (except for the  issuance  of  additional
shares of Series A Preferred  Stock which were authorized as of the Issue Date).
In order to avoid doubt,  any such  amendment,  alteration  or repeal that would
authorize,  create or increase the authorized amount of any additional shares of
Junior  Stock or that would  decrease  (but not below the number of shares  then
outstanding)  the number of authorized  shares of Preferred Stock will be deemed
not to  adversely  affect  such  powers,  preferences  or rights and will not be
subject  to  approval  by the  holders  of shares of Series A  Preferred  Stock.
Anything in the  foregoing  to the contrary  notwithstanding,  no consent of the
holders of the shares of Series A  Preferred  Stock will be  required  if, at or
prior to the time when such  amendment,  alteration or repeal is to take effect,
provision is made for the  redemption of all shares of Series A Preferred  Stock
at the time outstanding.

     (f) Except as otherwise set forth in this  paragraph or as required by law,
the  holders  of  Series  A  Preferred   Stock  will  not  have  any   relative,
participating,  optional or other  special  voting  rights and  powers,  and the
consent  or vote of such  holders  will not be  required  for the  taking of any
corporate action by the Company or the Board.

     14. Liquidation Rights.

     (a) In the event of any  liquidation,  dissolution,  or  winding  up of the
affairs of the Company, whether voluntary or involuntary,  the holders of shares
of Series A Preferred  Stock then  outstanding,  after  payment or provision for
payment of the debts and other  liabilities of the Company,  will be entitled to
be paid out of the  assets of the  Company  available  for  distribution  to its
stockholders  (i) an amount per share of Series A Preferred  Stock in cash equal
to the Face  Value of such  share  plus  (ii) an amount  equal to all  dividends
accrued but unpaid on such Share, whether or not such unpaid dividends have been
declared or there are any funds of the Company legally available for the payment
of  dividends  (the  "Liquidation  Preference").  If the  assets of the  Company
available  for  distribution  to the holders of the shares of Series A Preferred
Stock  upon   dissolution,   liquidation  or  winding  up  of  the  Company  are
insufficient to pay in full the Liquidation Preference payable to the holders of
outstanding  shares of Series A Preferred Stock, the holders of shares of Series
A  Preferred  Stock  will  share  ratably  in such  distribution  of  assets  in
proportion to the amount which would have been payable on such  distribution  if
the  amounts to which the  holders of  outstanding  shares of Series A Preferred
Stock were otherwise  entitled had been paid in full. Except as provided in this
subparagraph,  holders of Series A  Preferred  Stock will not be entitled to any
other or further  distribution in the event of the  liquidation,  dissolution or
winding up of the affairs of the Company.

              (b) For the purposes of this paragraph, none of the following will
be deemed to be a voluntary or involuntary  liquidation,  dissolution or winding
up of the Company:

                                      B-15
<PAGE>

          (i) the sale, lease,  transfer or exchange of all or substantially all
     of the assets of the Company; or

          (ii) the consolidation or merger of the Company with one or more other
     Persons   (whether  or  not  the  Company  is  the  Person  surviving  such
     consolidation or merger) or the  consummation of a statutory  binding share
     exchange involving the Company.

     15. Waiver.

     Any provision of this Certificate of Designation  which, for the benefit of
the holders of Series A Preferred Stock, prohibits,  limits or restricts actions
by the Company may be waived in whole or in part, or the  application  of all or
any part of such  provision in any particular  circumstance  or generally may be
waived,  in each case with the consent of the holders of at least  two-thirds of
the number of shares of Series A  Preferred  Stock then  outstanding,  either in
writing or by vote at a meeting  called for such purpose at which the holders of
Series A Preferred Stock vote as a separate class.

     16. Shareholder Reports.

     The  Company  will  provide to holders of Shares the  quarterly  and annual
reports to  shareholders,  proxy statements and other reports as are provided to
holders of Common Stock, such reports to be provided to holders of Shares at the
same time that they are provided to holders of Common Stock.

     17. Status of Redeemed or Converted Shares.

     All shares of Series A Preferred Stock redeemed or converted by the Company
will be retired and will not he reissued as Series A Preferred Stock.

     18. Exclusion of Other Rights.

     Except  as may  otherwise  be  required  by law,  the  shares  of  Series A
Preferred  Stock will not have any  designations,  preferences,  limitations  or
relative rights other than those  specifically  set forth in this Certificate of
Designation.

     19. Unclaimed Dividends.

     Any and  all  right,  title,  interest  and  claim  in or to any  dividends
declared by the Company,  which are  unclaimed  for a period of four years after
the close of business on the payment  date,  will be and be deemed  extinguished
and abandoned;  and such unclaimed dividends in the possession of the Company or
other agents or depositories,  will at such time become the absolute property of
the Company, free and clear of any and all claims of any persons whatsoever.

Item 15. Indemnification of Directors and Officers

     Section  7-109-102 of the  Colorado  Business  Corporation  Act (the "Act")
provides,  generally,  that a corporation may indemnify a person made a party to
any  threatened,  pending,  or completed  action,  suit, or proceeding,  whether
civil, criminal, administrative, or investigative and whether formal or informal
(a "Proceeding"),  because the person is or was a director of the corporation or
an individual  who,  while serving as a director of the  corporation,  is or was
serving at the corporation's request as a director,  officer,  partner, trustee,
employee or fiduciary or agent of another  corporation or other entity or of any
employee  benefit plan (a  "Director"),  against any  obligation  incurred  with
respect to a Proceeding to pay a judgment, settlement,  penalty, fine (including
an excise tax assessed  with respect to an employee  benefit plan) or reasonable
expenses incurred in the Proceeding if he conducted himself in good faith and he
reasonably  believed,  in the case of conduct in an official  capacity  with the
corporation,  his conduct was in the  corporation's  best  interests and, in all
other  cases,  his conduct was at least not  opposed to the  corporation's  best
interest  and,  with respect to any criminal  proceedings,  he had no reasonable
cause to believe that his conduct was unlawful; provided, however, a corporation
may not  indemnify a Director in  connection  with any  Proceeding  by or in the
right of the  corporation  in which  the  Director  was  adjudged  liable to the
corporation  or, in connection with any other  Proceeding  charging the Director
derived an improper  personal  benefit,  whether or not involving  actions in an
official  capacity,  in which  Proceeding  the Director was judged liable on the
basis  that  he  derived  an  improper  personal  benefit.  Any  indemnification
permitted in connection  with a Proceeding by or in the right of the corporation
is limited to reasonable  expenses  incurred in connection with such Proceeding.
Under Section 7-109-107 of the Act, unless otherwise provided in the Articles of
Incorporation,  a corporation may indemnify an officer, employee,  fiduciary, or
agent of the  corporation  to the same extent as to a Director and may indemnify
an  officer,  employee,  fiduciary,  or agent who is not a Director to a greater
extent,  if not  inconsistent  with  public  policy and if  provided  for by its
bylaws, general or specific action of its board of directors or shareholders, or
contract.

                                      II-1
<PAGE>

     Section  7-108-402  of the Act  provides,  generally,  that the Articles of
Incorporation  may contain a provision  eliminating  or  limiting  the  personal
liability  of a director to the  corporation  or its  shareholders  for monetary
damages  for  breach  of  fiduciary  duty as a  director;  except  that any such
provision  may not  eliminate  or limit the  liability of a director (i) for any
breach of the director's 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) acts specified in ss.  7-108-403,  or (iv)
any transaction from which a director directly or indirectly derived an improper
personal  benefit.  Such  provision  may  eliminate or limit the  liability of a
director  for any act or  omission  occurring  prior to the  date on which  such
provision becomes effective.

     Article VI of the Company's  Amended and Restated Articles of Incorporation
(the "Articles"), provides as follows:

     1.        A director of the Corporation  shall not be personally  liable to
          the Corporation or its stockholders for monetary damages for breach of
          fiduciary duty as a director,  except for liability (i) for any breach
          of the director's loyalty to the Corporation or its stockholders, (ii)
          for acts or omissions not in good faith or which  involve  intentional
          misconduct or a knowing  violation of law, (iii) under Section 7-5-114
          of the Colorado  Corporation  Code, or (iv) for any  transaction  from
          which the  director  derived any  improper  personal  benefit.  If the
          Colorado   Corporation   Code  is  amended   after   approval  by  the
          stockholders  of this article to authorize  corporate  action  further
          eliminating or limiting the personal liability of directors,  then the
          liability  of a director of the  Corporation  shall be  eliminated  or
          limited to the fullest  extent  permitted by the Colorado  Corporation
          Code, as amended.

               Any repeal or  modification  of the  foregoing  paragraph  by the
          stockholders of the Corporation  shall not adversely  affect any right
          or protection of a director of the Corporation existing at the time of
          such repeal or modification.

     2.        A.  Right to  Indemnification.  Each  person who was or is made a
          party or is threatened to be made a party to or is otherwise  involved
          any   action,   suit   or   proceeding,   whether   civil,   criminal,
          administrative  or  investigative  (hereinafter  a  "proceeding"),  by
          reason  of the  fact  that  he or she is or was a  director,  officer,
          employee  or  agent of the  Corporation  or is or was  serving  at the
          
                                      II-2
<PAGE>

          request  of  the  Corporation  as  a  director,   officer  of  another
          corporation  or  of a  partnership,  joint  venture,  trust  or  other
          enterprise,  including  service with respect to employee benefit plans
          (hereinafter an "indemnitee"), whether the basis of such proceeding is
          alleged  action  in  an  official  capacity  as a  director,  officer,
          employee  or  agent  or in  any  other  capacity  while  serving  as a
          director,  officer,  employee or agent,  shall be indemnified and held
          harmless by the  Corporation to the fullest  extent  authorized by the
          Colorado  Corporation  Code,  as the same exists or may  hereafter  be
          amended  (but, in the case of any such  amendment,  only to the extent
          that  such  amendment  permits  the  Corporation  to  provide  broader
          indemnification  rights than such law  permitted  the  Corporation  to
          provide prior to such amendment),  against all expense,  liability and
          loss (including attorneys' fees, judgments,  fines, ERISA excise taxes
          or penalties and amounts paid in settlement),  reasonably  incurred or
          suffered  by  such   indemnitee  in  connection   therewith  and  such
          indemnification  shall  continue as to an indemnitee who has ceased to
          be a  director,  officer,  employee  or agent and  shall  inure to the
          benefit  of  the  indemnitee's   heirs  or  personal   representative;
          provided,  however,  that except as provided in subparagraph B. hereof
          with respect to proceedings to enforce rights to indemnification,  the
          Corporation  shall  indemnify any such indemnitee in connection with a
          proceeding (or part thereof) initiated by such indemnitee only if such
          proceeding  (or part thereof) was authorized by the Board of Directors
          of the  Corporation.  The right to  indemnification  conferred in this
          paragraph shall be a contract right . . .

               B.  Right  of   Indemnitee  to  Bring  Suit.  If  a  claim  under
          subparagraph  A  of  this  paragraph  is  not  paid  in  full  by  the
          Corporation  within sixty days after a written claim has been received
          by the  Corporation,  except in the case of a claim for an advancement
          of expenses, in which case the applicable period shall be twenty days,
          the  indemnitee  may at any time  thereafter  bring suit  against  the
          Corporation  to recover the unpaid amount of the claim.  If successful
          in  whole  or in part in any  such  suit or in a suit  brought  by the
          Corporation  to recover an  advancement  of  expenses  pursuant to the
          terms of an undertaking,  the indemnitee  shall be entitled to be paid

                                      II-3
<PAGE>

          also the expense of  prosecuting  or defending  such suit.  In (i) any
          suit brought by the  indemnitee to enforce a right to  indemnification
          hereunder  (but not in a suit brought by the  indemnitee  to enforce a
          right to an  advancement  of  expenses) it shall be a defense that the
          indemnitee has not met the applicable standard of conduct set forth in
          the Colorado Corporation Code, and (ii) any suit by the Corporation to
          recover  an  advancement  of  expenses  pursuant  to the  terms  of an
          undertaking the Corporation shall be entitled to recover such expenses
          upon a  final  adjudication  that,  the  indemnitee  has  not  met the
          applicable  standard of conduct set forth in the Colorado  Corporation
          Code.  Neither the failure of the Corporation  (including its Board of
          Directors,  independent  legal counsel,  or its  stockholders) to have
          made a  determination  prior to the  commencement  of such  suit  that
          indemnification  of the  indemnitee  is  proper  in the  circumstances
          because the indemnitee has met the applicable  standard of conduct set
          forth in the Colorado Corporation Code, nor an actual determination by
          the Corporation  (including its Board of Directors,  independent legal
          counsel,  or its  stockholders)  that the  indemnitee has not met such
          applicable  standard of conduct,  shall create a presumption  that the
          indemnitee has not met the  applicable  standard of conduct or, in the
          case of such a suit  brought by the  indemnitee,  be a defense to such
          suit.  In any  suit  brought  by the  indemnitee  to  enforce  a right
          hereunder, or by the Corporation to recover an advancement of expenses
          pursuant to the terms of an  undertaking,  the burden of proving  that
          the   indemnitee  is  not  entitled  to  be  indemnified  or  to  such
          advancement of expenses under this paragraph or otherwise  shall be on
          the Corporation.

               C.  Non-Exclusivity of Rights. The rights to indemnification  and
          to the  advancement of expenses  conferred in this paragraph shall not
          be exclusive of any other right which any person may have or hereafter
          acquire under any statute, this Certificate of Incorporation,  by-law,
          agreement,  vote of stockholders or  disinterested  directors and does
          not restrict the Corporation's  right to limit the personal  liability
          of a director to the Corporation or to its  shareholders  for monetary
          damages for breach of fiduciary duty as a director,  or any other acts
          which are consistent  with the provisions of the Colorado  Corporation
          Code as the same exists or may hereafter be amended.

                                      II-4
<PAGE>

     The Company has entered into  indemnification  agreements  with each person
who  is a  director  of  the  Company  (each  director,  an  "indemnitee").  The
indemnification  agreements  provide  for  indemnification  against  any and all
damages,  judgments,  settlements and costs, costs of investigation and costs of
defense of legal actions, claims, or proceedings and appeals therefrom and costs
of attachment or similar bonds which indemnitee becomes legally obligated to pay
because of any claim or claims  made  against  indemnitee  because of any act or
omission  or neglect or breach of duty,  including  any actual or alleged  error
misstatement or misleading  statement,  which he commits or suffers while acting
in his capacity as a director of the Company or of certain  subsidiaries  of the
Company and solely because of his being a director;  and for the  advancement or
reimbursement  of  reasonable  expenses  (including   attorneys'  fees)  if  the
indemnitee  furnishes the Company a written affirmation of his good faith belief
he has met the standard of conduct permitting  indemnification  under applicable
law,  the  director  furnishes  the Company a written  undertaking  to repay the
advance if it is determined  he did not meet such  standard of conduct,  and the
Company  determines that the facts then known to those making the  determination
will not preclude  indemnification  under Colorado law provided that the Company
shall not have  determined  that the  director  would not be  permitted to be so
indemnified under applicable law.

     In addition,  the  indemnification  agreement  provides that if the Company
determines that the director is not permitted to be indemnified, the director is
not required to reimburse the Company until a final  judicial  determination  is
made with respect  thereto as to which all rights of appeal  therefrom have been
exhausted or lapsed and the Company is not obligated to indemnify or advance any
additional  amounts to the director  (unless there has been a determination by a
court of competent  jurisdiction  that the director  would be permitted to be so
indemnified under applicable law). The  indemnification  agreements also entitle
the director to be paid the expense of  prosecuting a claim against a company to
collect an indemnity  claim or  advancement  of expenses  from the Company.  The
Company is not liable to make any payment  under the  indemnification  agreement
(i) to the extent  payment is actually  made to the director  under an insurance
policy;  (ii) to the extent the director is entitled to indemnity and/or payment
under an insurance  policy;  (iii) to the extent the director is  indemnified by
the Company otherwise than pursuant to the  indemnification  agreement;  (iv) to
the extent such  indemnity is  prohibited  under  Colorado  law, the Amended and
Restated  Articles  of  Incorporation  or  other  applicable  law;  (v)  for  an
accounting  of  profits  made  from  the  purchase  or sale by the  director  of
securities of the Company  within the meaning of Section 16(b) of the Securities
Exchange Act of 1934 and amendments  thereto or similar  provisions of any state
statutory  law or common  law;  or (vi) if a court  holds  that such  payment is
prohibited by applicable law or is against public policy.

     The  Company  may  purchase  liability   insurance  policies  covering  its
directors and officers.

Item 17. Undertakings

     The undersigned Registrant hereby undertakes:

          1. To file, during any period in which offers or sales are being made,
     a post- effective amendment to this Registration Statement:

               (i) To include any Prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

               (ii) To reflect  in the  Prospectus  any facts or events  arising
          after the effective  date of the  Registration  Statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the Registration Statement;

               (iii) To include any  material  information  with  respect to the
          plan of  distribution  not  previously  disclosed in the  Registration
          Statement  or  any  material   change  to  such   information  in  the
          Registration Statement;

          2.  That,  for the  purpose of  determining  any  liability  under the
     Securities Act of 1933, each such post-effective  amendment 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.

          3. To remove from registration by means of a post-effective  amendment
     any  of  the  securities  being  registered  which  remain  unsold  at  the
     termination of the offering.

          4.  That,  for  purposes  of  determining   any  liability  under  the
     Securities  Act of 1933,  each  filing of the  Registrant'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 the 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.

     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.

Exhibit 4(e)


                                January _, 1997
Dear Shareholder:

     Your subscription certificate (the "Certificate")  representing your rights
to purchase  Series A 7%  Convertible  Preferred  Stock  ("Preferred  Stock") of
Columbus  Energy  Corp.  ("Columbus")  is contained  in this  envelope's  window
address.  Enclosed with this letter is a Prospectus  dated January _, 1997 and a
return envelope to be used for subscription exercise purposes.

     We encourage  you to read  carefully  the enclosed  Prospectus  for details
concerning the Company and the offering  before making a decision  regarding the
disposition of the enclosed Certificate.

     The  Certificate  should be in an amount of rights  equal to the  number of
Columbus shares owned by you of record as of the close of business on January -.
1997.  These rights will permit you to purchase one share of Preferred Stock for
$25.00 per share for each eight rights submitted by you when accompanied by your
check equal to the total amount required for the shares being acquired after the
appropriate  section on the reverse side of the Certificate has been filled out,
or in the alternative,  those  shareholders who are purchasing round lots of 100
shares of Preferred  Stock,  may  substitute in lieu of cash up to 100 shares of
Columbus'  common  stock and  receive a credit of $12.50 for each  common  share
relinquished  (up to a maximum of $1,250) toward the $2,500  purchase price each
round lot being acquired.  Also, should you desire to round up to th nearest 100
shares of Preferred Stock (which  requires  exactly 800 rights but you have less
than that  number),  you may so indicate  this to Harris  Trust of New York (the
"Subscription  Agent") who will buy rights for you (free of  commission)  not to
exceed 799 rights. Likewise, the Subscription Agent is authorized to sell rights
for you (free of commission) up to a total not to exceed 799 rights.

     A holder of a Certificate  is also entitled to  oversubscribe,  at the same
price,  and without  submitting  additional  rights,  for  unlimited  additional
shares.  This  oversubscription  will be subject to allotment  out of the shares
offered,  but not  subscribed  for,  under the primary  subscription  privilege,
provided  the holder has fully  exercised  his primary  subscription  privilege.
Subscription must be accompanied by payment of the full  subscription  price for
the primary subscription; however, only 20% of the purchase price, in cash only,
need be  enclosed  toward the  payment  for the shares  being  subscribed  by th
oversubscription  privilege.  You will be billed for the balance  should  shares
available  for  oversubscription  exceed 20% of the amount being  oversubscribed
which may be paid for in cash,  or a  combination  of cash and  common  stock as
permitted by the Primary Subscription.  If no oversubscription  shares or to the
extent that less than 20% of the amount being oversubscribed are available, such
payment will be refunded by the Subscription  Agent. No interest will be paid on
the refunded portion.

     In order to subscribe, you should execute the enclosed Certificate and mail
it  in  the  enclosed  envelope,  or  deliver  it,  with  full  payment  of  the
subscription price for all shares subscribed for, to Harris Trust Company of New
York, Wall Street Station, P. 0. Box 1010, New York, NY 10268-1010 so it will be
receive by the Subscription Agent prior to 4:00 p.m. E.S.T. on February -, 1997,
the expiration  date,  unless the offering has been extended  after  appropriate
public notice.  All Certificates not received by the Subscription  Agent by 4:00
p.m. E.S.T.,  February _, 1997, or the extended period, will expire and be of no
value.  Therefore, if you do not desire to exercise your rights, you should make
arrangements  to sell same  through  the  Subscription  Agent,  if less than 799
rights,  or through your broker if more. The rights are expected to trade on the
American  Stock  Exchange  throughout  the  offering  period  assuming  a market
develops and is sustained, but there can be no assurance this will occur.
<PAGE>

     It prior to the  expiration  date the  Subscription  Agent has received the
subscription price together with an undertaking in writing or by telegram from a
bank or trust company,  member firm of the New York or American Stock  Exchanges
or  other  national  securities  exchange,   that  duly  executed   Certificates
(specifying serial numbers thereof) have been or promptly will be transmitted to
the Subscription  Agent, such subscription will be accepted but Certificates for
the Preferred Stock  subscribed for will not be delivered until after receipt of
the Certificate.

     If you have any  questions,  they  should  be  addressed,  as  Promptly  as
possible, to Columbus or to the Subscription Agent at 212-701-7624.

Forwarding Agent,  Harris Trust Company of New York, 77 Water Street, 4th Floor,
New York,  NY 10005,  together  with payment by cash or by check,  bank draft or
money  order  payable  to the Rights  Agent of an amount in lawful  money of the

exercised  subscription  certificates  (specifying  serial numbers thereof) have
been or promptly will be  transmitted  to the Company or its Agents,  the Rights
Agent  shall  accept  such  subscription,  and  shall  deliver  certificates  so
subscribed only after receipt of the subscription agreements.  The Company shall
pay all federal and state  transfer  taxes,  if any,  required to be paid on the
issuance of Rights or of Preferred Stock upon exercise of Rights.
<PAGE>

     Once a  Registered  Holder  has  delivered  or  mailed a  completed  Rights
Certificate, the exercise of the Rights represented thereby is not revocable for
any reason.

     The Rights Agent shall issue the Rights  Shares after actual  collection of
the check,  draft or money order  tendered in the amount of the  Purchase  Price
therefor as soon as  practicable  following the  Expiration  Date subject to the
Oversubscription   Privilege.  No  subscriber  for  Rights  Shares  shall  be  a
shareholder  with respect to such Shares and no Rights Shares shall be deemed to
be outstanding until such Shares are issued in accordance herewith.

     All  monies  received  from  persons  who  exercise  the   Oversubscription
Privilege  by the  Rights  Agent  shall be held in trust  by the  Rights  Agent,
separate  and apart from  monies  received  from  persons  exercising  the basic
Subscription  Privilege.  The Rights  Agent  shall  have no duty to invest  such
monies and no  interest  shall be due or paid on monies  held in Trust.  As soon
after the  Expiration  Date as  practical,  the Rights  Agent  shall send to all
persons  whose  Oversubscription  Privilege  exercise has not been  accepted all
monies tendered by such persons.

     The Company shall not be obligated to issue any fractional  share interests
in  Rights  Shares  or to make  payment  in cash or scrip  for  such  fractional
interests,  which shall be of not value whatsoever. In the event that payment is
submitted in an amount less than that  required to purchase the number of Shares
subscribed,  only the number of whole Shares for which payment was received will
be  issued.  If a holder of Rights  subscribes  for fewer than all of the Shares
represented by his Rights Certificate, the Rights Agent shall issue a new Rights
Certificate  representing the balance of the unsubscribed  Rights Shares, to the
extent that there is sufficient time to do so prior to the Expiration Date.
<PAGE>

     Upon  request by a holder of record on the Record Date who holds Shares for
beneficial  owners,  the Rights Agent shall deliver Rights  Certificates  on the
same basis as if such  beneficial  owners  were  holders of record on the Record
Date.

     The Rights  Agent  shall hold all  payments  made in exercise of Rights for
investment,   transfer  or  other  action  in  accordance   with  the  Company's
instructions from time to time.

     All questions as to the validity,  form,  eligibility  (including  times of
receipt and matters  pertaining to beneficial  ownership)  and the acceptance of
subscriptions and the Purchase Price for Rights Shares will be determined by the
Company,  which  determinations  will be  final  and  binding.  No  alternative,
conditional or contingent  subscriptions will be accepted.  The Company reserves
the absolute right to reject any or all subscriptions not properly  submitted or
the  acceptance  of which would,  in the opinion of the  Company's  counsel,  be
unlawful.  The Company also  reserves the right to waive any  irregularities  or
conditions, and the Company's interpretations of the terms and conditions of the
offering  of the  Rights  shall be final  and  binding.  Any  irregularities  in
connection  with  subscriptions  must be cured  within  such time as the Company
shall determine,  unless waived.  Subscriptions  will not be deemed to have been
made until such irregularities have been cured or waived. The Rights Agent shall
promptly notify the Company of any irregularities in any subscriptions  received
by the Rights Agent. Rights  Certificates  received by the Rights Agent that are
not properly submitted and as to which the irregularities have not been cured or
waived  shall be returned by the Rights Agent to the  appropriate  holder of the
Rights,  to the extent there is sufficient time to do so prior to the Expiration
Date;  and funds  submitted  with such  Rights  Certificates  shall be  returned
without interest by the Rights Agent to such holder.
<PAGE>

     The Rights Agent is hereby  authorized and directed to accept  instructions
with  respect to the  performance  of its duties  hereunder  from an  authorized
officer of the Company, or such officer's designee, and to apply to such officer
or designee  for  written  instructions  in  connection  with its duties,  which
written  instructions shall be promptly provided to the Rights Agent. The Rights
Agent  shall not be liable for any action  taken or suffered by it in good faith
in accordance with the advice or  instructions of any authorized  officer of the
Company or such officer's designee.

     5.  Purchase and Sale of Rights.  The Rights  Agent  shall,  on request and
without charge to the registered holder, handle orders to buy (not exceeding 799
Rights on any one  subscription) or sell Rights (not exceeding 799 Rights on any
one  subscription)  for the account of any Registered  Holder in order to assist
such holder in rounding out his  subscription  for 100 shares of Preferred Stock
or disposing  of his Rights.  The Company  will pay the Rights  Agent's  service
charge on such  purchases  and  sales.  The  Rights  Agent may match  buying and
selling orders in the execution of such orders subject to the Rights Agent being
able to find purchasers or sellers. Charges or credits upon purchase and sale of
Rights,  including matched orders, on each day will be at the average price paid
or received by the Rights  Agent in the open market for the Rights  purchased or
sold. The Rights Agent will bill the Registered  Holders for the costs of Rights
purchased or mail a check for the proceeds due from the Rights sold.

     6. Loss or Mutilation.  Upon receipt by the Company and the Rights Agent of
evidence  satisfactory  to  them  of the  ownership  of  and  the  loss,  theft,
destruction  or mutilation of any Rights  Certificate  and (in the case of loss,
theft or  destruction)  of indemnity  satisfactory  to them, and (in the case of
mutilation) upon surrender and cancellation of the mutilated Rights Certificate,
the  Rights  Agent  shall  deliver  in lieu  thereof  a new  Rights  Certificate
representing  an equal aggregate  number of Rights.  Applicants for a substitute
Rights Certificate shall also comply with such other reasonable  regulations and
pay such reasonable charges as the Rights Agent may prescribe.

     7.  Liability of the Rights  Agent.  The Rights Agent shall not, by issuing
and delivering Rights  Certificates or by any other act hereunder,  be deemed to
make any  representations  as to the validity or value or  authorization  of the
Rights Certificates or the Rights represented thereby or of the Rights Shares or
other  property  delivered  upon  exercise  of any Rights or whether  the Rights
Shares are duly authorized, fully paid and nonassessable. The Rights Agent shall
not (a) be liable for any recital or statement of fact  contained  herein or for
any  action  taken,  suffered  or  omitted  by  it in  reliance  on  any  Rights
Certificate or other  document or instrument  believed by it in good faith to be
genuine and to have been signed or presented by the proper party or parties; (b)
be responsible  for any failure on the part of the Company to comply with any of
its  covenants  and  obligations  contained  in this  Agreement or in the Rights
Certificates;  or (c) be liable to any act or omission in  connection  with this
Agreement except for its own negligence or willful misconduct.
<PAGE>

     8.  Indemnification.  The Company  agrees to indemnity the Rights Agent and
save it harmless from and against any and all losses,  expenses and liabilities,
including,  without limitation,  judgments, costs and counsel fees, for anything
done or omitted by the Rights  Agent in the  execution  of its duties  hereunder
except  losses,  expenses  and  liabilities  arising  as a result of the  Rights

     Section 1.5.  Calculations and Determinations.  All interest accruing under
the Loan  Documents  shall be  calculated  on the basis of actual  days  elapsed
(including  the first day but  excluding the last) and a year of: (a) 365 or 366
days, as appropriate, with respect to Prime Rate Advances, and (b) 360 days with
respect to LIBOR Advances.  Unless otherwise expressly provided herein or unless
Lender otherwise  consents,  all financial  statements and reports  furnished to
Lender   hereunder  shall  be  prepared  and  all  financial   computations  and
determinations pursuant hereto shall be made in accordance with GAAP.

     Section 1.6.  Accounting  Principles.  Where the character or amount of any
asset or liability or item of income or expense is required to be  determined or
other  accounting  computation  is required to be made for the  purposes of this
Agreement,  this  shall be done in  accordance  with  GAAP,  except  where  such
principles are inconsistent  with the requirements of this Agreement.  If one or
more changes in GAAP after the date of this Agreement are required to be applied
to existing  transactions,  and a violation  of one or more of the terms of this
Agreement  shall have  occurred  which  would not have  occurred if no change in
accounting principles had taken place:

          (a) The parties agree that such  violation  shall not be considered to
     constitute an Event of Default for a period of 90 days;

          (b) The  parties  agree in such  event to  negotiate  in good faith to
     attempt to draft an amendment of this Agreement which shall  approximate to
     the extent possible the economic effect of the original financial covenants
     after taking into account such change or changes in GAAP; and

          (c) If the parties are unable to negotiate such an amendment within 90
     days,  Borrower shall have the option of (a) prepaying the Loan in full, or
     (b) submitting the drafting of such an amendment to binding arbitration. If
     Borrower does not exercise  either such option within said period,  then as
     used in this  Agreement  GAAP shall mean such  principles  in effect at the
     time of determination.

     Section 2.1.  The Loan.  (a) Subject to the other terms and  conditions  of
this  Agreement,  Lender  agrees to: (i) make  Advances to Borrower from time to
time  requested  upon written notice to Lender from Borrower no later than noon,
Denver time, at least one Business Day prior to any Prime Rate  Advance,  and no
later than noon,  Denver time,  at least three  Business Days prior to any LIBOR
Advance,  and (ii) issue  Letters  of Credit  from time to time  requested  upon
written notice to Lender from Borrower no later than five days prior to the date
of issuance of such Letter of Credit.

          (b) Each  request by Borrower  for an Advance  shall be in the form of
     Exhibit B attached hereto and made a part hereof.  Each request by Borrower
     for the  issuance  of a Letter of Credit  shall be in the form of Exhibit C
     attached  hereto and made a part  hereof,  and shall be  accompanied  by an
     application  for  issuance of a letter of credit on Lender's  then-standard
     form, duly executed by Borrower.

          (c) Lender shall not have any obligation to: make an Advance after the
     Commitment  Expiration  Date  (except  an Advance  made for the  purpose of
     repaying a prior Advance and thereby:  (A)  beginning a new LIBOR  Interest
     Period,  (B)  converting a prior LIBOR Advance to a Prime Rate Advance,  or
     (C)  converting a prior Prime Rate Advance to a LIBOR Advance) , (ii) issue
     or renew a Letter of Credit which does not expire  prior to the  Commitment
     Expiration  Date, (iii) make a LIBOR Advance as to which the LIBOR interest
     Period  does not  expire  prior to the  Maturity  Date,  (iv)  make a LIBOR
     Advance  at any  time  when  three  or more  prior  LIBOR  Advances  remain
     outstanding,  (v) make a Prime Rate Advance in an amount less than $50,000,
     (vi) make a LIBOR Advance in an amount less than $500,000, or (vii) make an
     Advance or issue a Letter of Credit which would cause the aggregate  amount
     of all Advances  outstanding  hereunder plus the face amount of all Letters
     of Credit outstanding hereunder to exceed the Commitment Amount.

          (d) Each payment by Lender under a Letter of Credit shall be deemed to
     be a Prime Rate Advance  bearing  interest  from the date of such  payment,
     shall be entitled to all  benefits of the Security  Documents  and shall be
     subject  to all terms of this  Agreement  and any and all other  applicable
     Loan Documents.

          (e) Within the limitation of the Commitment  Amount and subject to the
     other terms and provisions hereof,  Borrower may borrow, repay and reborrow
     hereunder.  The  Advances  and Letters of Credit  described  above shall be
     herein  collectively  referred to as the "Loan".  Borrower hereby expressly
     requests and irrevocably authorizes Lender to make the Loan.

     Section 2.2. The Note.  (a) Borrower's  obligation to repay the Loan,  with
interest  thereon,  shall be evidenced by the Note.  In the event any  provision
contained in the Note  conflicts with a provision  contained in this  Agreement,
the provisions of this Agreement shall control.

          (b)(i)  Except as provided in (ii) below:  (A)  interest on each Prime
     Rate Advance shall accrue at a  fluctuating  annual rate equal to the Prime
     Rate, and (B) interest on each LIBOR Advance shall accrue at a fixed annual
     rate equal to LIBOR  (Adjusted) with respect to such LIBOR Advance plus one
     and three-quarters  percentage points per annum;  provided that interest on
     each LIBOR  Advance made on or after  September  23, 1996 shall accrue at a
     fixed  annual  rate equal to LIBOR  (Adjusted)  with  respect to such LIBOR
     Advance  plus one and  one-half  percentage  points  per  annum.  (ii) With
     respect to any  amount  payable  hereunder  or under the Note or any of the
     other Loan Documents, which is not paid when due, whether upon maturity, by
     acceleration or otherwise,  interest thereon shall accrue from the due date
     until the date of payment at a fixed annual rate equal to the Prime Rate as
     of the due date plus five percentage points per annum.

          (c) Interest on Prime Rate  Advances  shall be payable  monthly on the
     first Business Day of each calendar month, commencing November 1, 1996, and
     ending on the  Maturity  Date.  Interest  on each  LIBOR  Advance  shall be
     payable  on the last  day of the  LIBOR  Interest  Period  for  such  LIBOR
     Advance.  All accrued and unpaid interest will be due and payable not later
     than the Maturity Date.

     Section  2.3.  Mandatory  Principal  Payments.  (a)  Borrower  shall make a
principal  payment on each Principal Payment Date, each such payment to be in an
amount equal to the Minimum Principal  Payment;  provided that any such payments
shall be in addition to any  amounts  payable by Borrower  pursuant to the other
provisions of this Section 2.3.

          (b) If for any reason the aggregate  outstanding  principal balance of
     all Advances plus the aggregate face amount of all  outstanding  Letters of
     Credit shall exceed the Commitment  Amount,  Borrower shall, not later than
     30 days after written notice thereof from Lender:  (i)  immediately pay the
     excess to  Lender  in a lump sum;  and/or  (ii)  commence  (and  thereafter
     continue) an  amortization  schedule under which Borrower repays the excess
     in six  equal  monthly  principal  installments  on the  first  day of each
     calendar month,  which amounts shall be in addition to the monthly interest
     payments and any other  principal  payments  otherwise  due,  such that the
     entire  excess is paid within six months;  and/or (iii) execute and deliver
     to  Lender  additional   mortgages,   supplements  to  mortgages  or  other
     instruments  satisfactory in form and substance  satisfactory to Lender, by
     which Borrower  mortgages,  pledges or hypothecates to Lender, or creates a
     security interest in for the benefit of Lender,  sufficient  additional Oil
     and  Gas  Interests  to  induce  Lender  to make a  redetermination  of the
     Borrowing Base such that the Commitment Amount is increased to an amount no
     less than the aggregate  outstanding principal balance of all Advances plus
     the aggregate face amount of all outstanding Letters of Credit.

                                      -12-
<PAGE>

          (c) The outstanding  principal balance of all Advances,  together with
     all unpaid fees and  expenses,  shall be due and payable not later than the
     Maturity Date.

     Section 2.4. Voluntary Prepayments. Borrower shall have the right to prepay
any or all Advances at any time, in whole or in part, without penalty or premium
(except as otherwise described in Section 3.5 below) ; provided that, during the
Revolving  Period,   Borrower  shall  not  at  any  time  reduce  the  aggregate
outstanding principal amount of all Advances to less than $10,000.

     Section 2.5.  Termination of  Commitment.  Borrower shall have the right at
any time and from time to time,  upon not less than three  Business  Days' prior
written or telegraphic  notice to Lender, to terminate the Commitment.  Upon any
termination of the Commitment,  Borrower shall, at the time of such termination,
prepay the Note in full. Any such prepayment shall be without penalty or premium
(except as otherwise described in Section 3.5 below).

     Section 2.6.  Payments to Lender.  Borrower will pay to Lender each payment
which  Borrower owes under the Loan  Documents not later than 1:00 p.m.,  Denver
time,  an the due date,  in lawful money of the United  States of America and in
immediately available funds. Any payment received after such time will be deemed
to have been made on the next  following  Business Day.  Should any such payment
become due and payable on a day other than a Business  Day, the maturity of such
payment shall be extended to the next succeeding  Business Day, and, in the case
of a payment of principal  or past due  interest,  interest  shall accrue and be
payable  thereon for the period of such  extension.  Each  payment  under a Loan
Document  shall be due and  payable  at the  place  provided  therein  or, if no
specific place of payment is provided,  shall be due and payable at the place of
payment of the Note.  When Lender  collects or receives  money on account of the
Obligations owing to it, Lender may apply such money as it elects to the various
Obligations then due and payable.

     Section 2.7. Use of Proceeds.  In no event shall the Loan  proceeds be used
directly  or  indirectly  for the  purpose,  whether  immediate,  incidental  or
ultimate, of purchasing, acquiring or carrying any "margin stock" or any "margin
securities"  (as  such  terms  are  defined  respectively  in  Regulation  U and
Regulation  G  promulgated  by the Board of  Governors  of the  Federal  Reserve
System) or to extend credit to others  directly or indirectly for the purpose of
purchasing  or carrying  any such margin  stock or margin  securities.  Borrower
represents and warrants to Lender that Borrower is not engaged  principally,  or
as one of Borrower's important  activities,  in the business of extending credit
to others for the purpose of  purchasing or carrying such margin stock or margin
securities.  Borrower  will use the Loan  proceeds  solely for  general  working
capital purposes of Borrower and CGSI in their U.S.  operations,  acquisition of
oil and gas properties and related assets and the issuance of standby letters of
credit in connection with the U.S. operations of Borrower and CGSI.

     Section  2.8.  Borrowing  Base  Procedures.  The  Borrowing  Base  will  be
re-determined annually by Lender, effective as of April I of each year until the
occurrence of the Maturity Date (and Lender shall redetermine the Borrowing Base
not more than one additional time in each annual period from April 1 through the
succeeding  March 31 at the  request of Lender and not more than one  additional
time in each such  annual  period at the  request of  Borrower),  based upon the
engineering  reports submitted by Borrower pursuant to Sections  6.1(b)(vii) and
6.1(b)(viii)  below and upon such  other  information  and data as Lender  deems
relevant.  Lender shall advise Borrower of each redetermination of the Borrowing
Base by Lender by providing to Borrower a Borrowing Base Notice by approximately
10 days prior to the effective date of any such re-determination;  provided that
if, due to any failure by Borrower to submit in a timely manner any  engineering
report or other information  required to be submitted by Borrower  hereunder or,
if requested in writing by Lender, any additional  information or data needed in
connection  with a  redetermination  of the  Borrowing  Base or due to any other
reason  beyond the control of Lender,  Lender does not provide a Borrowing  Base
Notice at the time  described  above,  then,  unless  Lender gives notice to the
contrary to  Borrower,  the  Borrowing  Base from the  previous  period shall be
carried  over  into the new  period  until a  Borrowing  Base  Notice is sent to
Borrower by Lender and the remainder of the procedures described in this Section
2.8 have been  completed.  Borrower  shall have the right,  by giving  notice to
Lender within five  Business  Days after its receipt of a Borrowing  Base Notice
for a Borrowing  Base  Period,  to elect to have a Reduced  Borrowing  Base take
effect for such Borrowing  Base Period;  provided that if Borrower has elected a
Reduced  Borrowing Base for a Borrowing  Base Period,  Borrower may, at any time
prior to the end of such  Borrowing  Base Period,  by giving five Business Days'
prior written  notice to Lender,  elect to increase the Borrowing  Base for that
Borrowing  Base  Period to an amount  not  greater  than the  amount  originally
included  by Lender in its  Borrowing  Base  Notice;  provided  further  that if
Borrower so elects to increase the  Borrowing  Base,  then all  commitment  fees
payable with respect to such Borrowing Base Period pursuant to Section 3.4 below
shall be calculated (or, as to any fees paid with respect to such Borrowing Base
Period prior to such election, adjusted as of the date upon which any commitment
fee is next payable) as if the increased  Borrowing  Base had been in effect for
the entire Borrowing Base Period.

     Section 3.1. The Security.  The Obligations will be secured by the Security
Documents listed in the Security Schedule and any additional  Security Documents
hereafter delivered by Borrower and accepted by Lender.

     Section 3.2.  Perfection  and  Protection of Security  Interests and Liens.
Borrower  will from time to time  deliver  to Lender any  financing  statements,
continuation  statements,  extension  agreements and other  documents,  properly

substance  reasonably  satisfactory to Lender,  which Lender may request for the
purpose of perfecting,  confirming or protecting Lender's Liens and other rights
in the Borrowing Base Properties.

     Section  3.3.  Bank  Accounts  and Offset.  To secure the  repayment of the
Obligations, Borrower hereby grants to Lender a security interest, a lien, and a
right of offset, each of which shall be upon and against (a) any and all moneys,
securities  or other  property  (and the proceeds  therefrom) of Borrower now or
hereafter held or received by or in transit to Lender from or for the account of
Borrower, whether for safekeeping, custody, pledge, transmission,  collection or
otherwise  (b)  any  and all  deposits  (general  or  special,  time or  demand,
provisional  or final) of Borrower  with Lender,  and (c) any other  credits and
claims of  Borrower  at any time  existing  against  Lender,  including  without
limitation  claims under  certificates  of deposit;  provided that the foregoing
shall not apply to amounts which  Borrower is holding as trustee for the benefit
of third parties. Upon the occurrence of any Event of Default,  Lender is hereby
authorized to foreclose upon,  offset,  appropriate,  and apply, at any time and
from time to time,  without  notice to Borrower,  any and all items  hereinabove
referred to against the  obligations  (whether or not such  Obligations are then
due and payable).

     Section 3.4. Fees.  (a) Borrower shall pay to Lender,  within 30 days after
the end of the period from the date of this Agreement  through December 31, 1996
and  of  each  subsequent  calendar  quarter  during  the  Revolving  Period,  a
commitment fee in an amount equal to: (i)  one-quarter of one percent per annum,
times (ii) the excess of the  Commitment  Amount  over the sum of the  aggregate
outstanding  principal  balance  of all  Advances  plus the face  amount  of all
outstanding  Letters  of Credit,  commuted  on a daily  basis for such  calendar
quarter or other period for which such commitment fee is being paid.

          (b) Borrower shall pay to Lender with respect to each Letter of Credit
     a fee in an amount equal to the greater of: (i) one percent per annum times
     the face amount of such Letter of Credit, or (ii) $500.00,  which fee shall
     be payable at the time of issuance  (and again at the time of any  renewal)
     of such Letter of Credit.

     Section 3.5. Special LIBOR Provisions. (a) If Lender shall determine (which
determination shall, upon notice thereof to Borrower,  be conclusive and binding
on Borrower  and  Lender)  that the  introduction  of or any change in or in the
interpretation  of any law  makes  it  unlawful,  or any  central  bank or other
governmental authority asserts that it is unlawful, for Lender to make, continue
or maintain any Advance as, or to convert any Advance into, a LIBOR Advance, the
obligations  of Lender to make,  continue,  maintain or convert any such Advance
shall, upon such determination, forthwith be suspended until Lender shall notify
Borrower that the circumstances causing such suspension no longer exist, and all
LIBOR Advances shall  automatically  convert into Prime Rate Advances at the end
of the then-current  LIBOR Interest  Periods with respect thereto or sooner,  if
required by such law or assertion.

          (b) If Lender shall determine that:

               (i) U.S.  Dollar  deposits  in the  relevant  amount  and for the
          relevant  LIBOR  Interest  Period are not  available  to Lender in its
          relevant market; or

               (ii) By  reason  of  circumstances  affecting  Lender's  relevant
          market, adequate means do not exist for ascertaining the interest rate
          applicable hereunder to LIBOR Advances;

then,  upon notice from Lender to  Borrower,  the  obligations  of Lender  under
Section  2.1 to make or  continue  any LIBOR  Advance  or to  convert  any prior
Advance into a LIBOR  Advance  shall  forthwith be suspended  until Lender shall
notify Borrower that the circumstances causing such suspension no longer exist.

                                      -16-

          (c) Borrower,  agrees to reimburse Lender for any increase in the cost
     to Lender  of, or any  reduction  in the  amount of any sum  receivable  by
     Lender in respect of, making, continuing,  converting or maintaining (or of
     its obligation to make,  continue,  convert or maintain) any LIBOR Advance.
     Lender shall promptly  notify  Borrower in writing of the occurrence of any
     such  event,  such  notice to state,  in  reasonable  detail,  the  reasons
     therefor and the additional  amount required fully to compensate Lender for
     such  increased cost or reduced  amount.  Such  additional  amount shall be
     payable by Borrower to Lender  within  five days of  Borrower's  receipt of
     such notice,  and such notice shall,  in the absence of manifest  error, be
     conclusive and binding on Borrower.

          (d) In the event Lender shall incur any loss or expense (including any
     loss or expense  incurred by reason of the  liquidation or  reemployment of
     deposits  or other funds  acquired by Lender to make,  continue or maintain
     any portion of the principal  amount of any LIBOR Advance or to convert any
     portion of the principal  amount of any prior Advance into a LIBOR Advance)
     as a result of:

               (i) Any  conversion  or repayment or  prepayment of the principal
          amount of any LIBOR  Advance on a date other than the  scheduled  last
          day of the LIBOR Interest Period applicable thereto;

               (ii) Any Advance not being made as a LIBOR Advance; or

               (iii) Any prior  Advance  not being  continued  as, or  converted
          into, a LIBOR Advance in accordance with the Advance request therefor;

then, upon the written notice of Lender to Borrower, Borrower shall, within five
days of its receipt  thereof,  pay Lender such amount as will (in the reasonable
determination of Lender) reimburse Lender for such loss or expense. Such written
notice (which shall include  calculations  in reasonable  detail) shall,  in the
absence of manifest error, be conclusive and binding on Borrower.

     Section  3.6.   Increased   Capital  Costs.   If  any  change  in,  or  the
introduction,  adoption,  effectiveness,  interpretation,   reinterpretation  or
phase-in of, any law or regulation,  directive,  guideline,  decision or request
(whether or not having the force of law) of any court,  central bank,  regulator
or other  governmental  authority  affects or would affect the amount of capital
required  or  expected  to be  maintained  by Lender or any  Person  controlling
Lender,  and Lender  determines (in its sole and absolute  discretion)  that the
rate or return on its or such  controlling  Person's capital as a consequence of
the Loan is reduced  to a level  below  that  which  Lender or such  controlling
Person could have  achieved  but for the  occurrence  of any such  circumstance,
then,  in any such case  upon  notice  from time to time by Lender to  Borrower,
Borrower  hereby  agrees  to  pay  immediately  to  Lender  additional   amounts
sufficient to compensate Lender or such controlling Person for such reduction in
rate of return.  A statement  to  Borrower  by Lender as to any such  additional
amount or amounts (including  calculations  thereof in reasonable detail) shall,
in the absence of manifest  error,  be  conclusive  and binding on Borrower.  In
determining such amount,  Lender may use any method of averaging and attribution
that it (in its sole and absolute discretion) shall deem applicable.

                                      -17-

     Section 3.7. Taxes.  All payments by Borrower of principal of, and interest
on,  the Loan and all other  amounts  payable  hereunder  shall be made free and
clear of and without deduction for any present or future income,  excise,  stamp
or franchise taxes and other taxes, fees, duties,  withholdings or other charges
of  any  nature  whatsoever  imposed  by any  taxing  authority,  but  excluding
franchise  taxes and taxes  imposed on or  measured  by  Lender's  net income or
receipts (such  nonexcluded  items being called "Taxes") . In the event that any
withholding  or deduction  from any payment to be made by Borrower  hereunder is
required  in  respect  of any Taxes  pursuant  to any  applicable  law,  rule or
regulation, Borrower will:

          (a) Pay directly to the relevant authority the full amount required to
     be so withheld or deducted;

          (b)  Promptly   forward  to  Lender  an  official   receipt  or  other
     documentation  satisfactory  to  Lender  evidencing  such  payment  to such
     authority; and

          (c) Pay Lender such  additional  amount or amounts as may be necessary
     to ensure  that the net amount  actually  received by Lender will equal the
     full amount Lender would have received had no such withholding or deduction
     been required.

Moreover,  if any Taxes are directly asserted against Lender with respect to any
payment  received by Lender  hereunder,  Lender may pay such Taxes and  Borrower
will promptly pay such additional amounts (including any penalties,  interest or
expenses) as may be  necessary  in order that the net amount  received by Lender
after the payment of such Taxes (including any Taxes on such additional  amount)
shall  equal the  amount  Lender  would  have  received  had not such Taxes been
asserted.

     If  Borrower  fails to pay any  Taxes  when due to the  appropriate  taxing
authority  or fail to remit to Lender the  required  receipts or other  required
documentary  evidence,  Borrower shall indemnify,  save and hold harmless Lender
from and against any  incremental  Taxes,  interest or penalties that may become
payable by Lender as a result of any such failure.

                                      -38-

Upon the  occurrence  of an Event of Default  described  in  subsection  (f)(i),
(f)(ii) or (f)(iii) of this section,  all of the obligations  shall thereupon be
immediately due and payable,  without presentment,  demand,  protest,  notice of
protest,  declaration or notice of acceleration  or intention to accelerate,  or
any other notice or declaration  of any kind, all of which are hereby  expressly
waived by Borrower and Guarantor.  During the  continuance of any other Event of
Default,  Lender at any time and from time to time (unless all Events of Default
have  theretofore  been  remedied)  may  declare  any or all of the  Obligations
immediately  due and  payable,  and all  such  obligations  shall  thereupon  be
immediately  due and  payable.  The term  "Grace  Period,"  as used  herein with
respect to an Event of Default for which a Grace Period is  expressly  provided,
means the period beginning on the date of the related Default and ending: (x) in
the case of a Default  described in section 7. 1 (a) above,  five  Business Days
after the occurrence of the Default;  (y) in the case of any Default (other than
a Default described in Section 7.1(a)) as to which Borrower does not give notice
of such Default to Lender as required in Section 6.1(d) prior to Lender's giving
notice  thereof to  Borrower  or  exercising  any of its rights or  remedies  in
connection  therewith,  15 days after written notice of such Default (a "Default
Notice")  is given  by  Lender  to  Borrower;  and (z) in the case of any  other
Default for which a Grace Period is expressly provided,  30 days after a Default
Notice is given by Lender to Borrower.

     Section 7.2.  Remedies.  If any Default or Event of Default shall occur and
be  continuing,  the  obligation of Lender to make Advances under this Agreement
shall  terminate  immediately.  if any Event of Default shall occur,  Lender may
protect and  enforce  its rights  under the Loan  Documents  by any  appropriate
proceedings,  including  proceedings for specific performance of any covenant or
agreement contained in any Loan Document,  and Lender may enforce the payment of
any Obligations due or enforce any other legal or equitable  right.  All rights,
remedies  and powers  conferred  upon Lender under the Loan  Document;  shall be
deemed  cumulative  and not  exclusive of any other  rights,  remedies or powers
available under the Loan Documents or at law or in equity.

     Section 7.3.  Indemnity.  Borrower  hereby agrees to indemnify,  defend and
hold  harmless  Lender and its  agents,  affiliates,  officers,  directors,  and
employees from and against any and all claims, losses, demands,  actions, causes
of action, and liabilities  whatsoever  (including without limitation reasonable
attorney's  fees and  expenses,  and costs and expenses  reasonably  incurred in
investigating,  preparing or defending against any litigation or claim,  action,
suit, proceeding or demand of any kind or character) arising out of or resulting
from:  (a) the Loan Documents  (including  without  limitation  the  enforcement
thereof),  except  to the  extent  such  claims,  losses,  and  liabilities  are
proximately caused by Lender's gross negligence or willful  misconduct,  and (b)
the  contamination  of any of the  Borrowing  Base  Properties  by any hazardous
substance or environmental pollutant in violation of any federal, state or local
environmental  statute,   rule,  regulation  or  ordinance,   including  without
limitation violation of the Comprehensive  Environmental Response,  Compensation
and Liability Act, as amended from time to time, or of the Resource Conservation
and Recovery Act, as amended from time to time.

                                  Miscellaneous

     Section  8.1.  Waiver  and  Amendment.  No  failure  or delay by  Lender in
exercising  any right,  power or remedy  which it may have under any of the Loan
Documents  shall  operate as a waiver  thereof or of any other  right,  power or
remedy,  nor shall any single or partial  exercise  by Lender of any such right,
power or remedy preclude any other or further  exercise  thereof or of any other
right,  power or remedy.  No waiver of any provision of any Loan Document and no
consent  to any  departure  therefrom  shall ever be  effective  unless it is in
writing and signed by Lender, and then such waiver or consent shall be effective
only in the specific  instances  and for the purposes for which given and to the
extent specified in such writing. No notice to or demand on any obligated Person
shall in any case of itself entitle any Obligated Person to any other or further
notice or demand in similar or other circumstances. This Agreement and the other
Loan Documents set forth the entire  understanding  between the parties  hereto,
and no modification or amendment of or supplement to this Agreement or the other
Loan  Documents  shall be valid or  effective  unless the same is in writing and
signed by the party against whom it is sought to be enforced.

     Section  8.2.  Survival  of  Agreements;  Cumulative  Nature.  All  of  the
Obligated Persons' various representations, warranties, covenants and agreements
in the Loan Documents shall survive the execution and delivery of this Agreement
and the other Loan Documents and the performance  hereof and thereof,  including
without  limitation  the making or granting of the Loan and the  delivery of the
Note and the other Loan  Documents,  and shall further  survive until all of the
obligations  are  paid in full to  Lender  and all of  Lender's  obligations  to
Borrower  are  terminated.  All  statements  and  agreements  contained  in  any
certificate  or other  instrument  delivered by any  obligated  Person to Lender
under  any Loan  Document  shall be deemed  representations  and  warranties  by
Borrower to Lender  and/or  agreements  and  covenants  of  Borrower  under this
Agreement. The representations,  warranties, and covenants made by the obligated
Persons in the Loan Documents, and the rights, powers, and privileges granted to
Lender in the Loan  Documents,  are  cumulative,  and no Loan Document  shall be
construed in the context of another to diminish,  nullify,  or otherwise  reduce
the benefit to Lender of any such  representation,  warranty,  covenant,  right,
power or privilege.  In particular and without limitation,  no exception set out
in this Agreement to any  representation,  warranty or covenant herein contained
shall apply to any similar representation, warranty or covenant contained in any
other Loan Document, and each such similar representation,  warranty at covenant
shall be subject only to those exceptions which are expressly made applicable to
it by the terms of the various Loan Documents.

first  attempted  delivery  at the  address  and in the manner  provided  herein
(provided that the notifying  party promptly  takes  reasonable  steps to effect
actual delivery if the first  attempted  delivery is  unsuccessful),  or, in the
case of telegram  or telex,  upon  receipt.  All such  notices to any  Obligated
Person  may,  at the  option of Lender in each  particular  instance,  be either
addressed and delivered to such  Obligated  Person or addressed and delivered to
Borrower.

     Section  8.4.  Joint  and  Several  Liability;  Parties  in  Interest.  All
Obligations  which are owed by two or more Obligated  Persons shall be joint and
several, and not merely joint, obligations. All grants, covenants and agreements
contained  in the Loan  Documents  shall  bind and inure to the  benefit  of the
parties thereto and their respective successors and assigns; provided,  however,
that no  Obligated  Person may assign or transfer  any of its rights or delegate

     Section 8.5.  Governing Law. The Loan Documents  shall be deemed  contracts
and  instruments  made  under  the laws of the  State of  Colorado  and shall be
construed and enforced in accordance  with and governed by the laws of the State
of  Colorado  and the laws of the United  States of  America,  except (a) to the
extent  that the law of  another  jurisdiction  is  expressly  elected in a Loan
Document,  and (b) with respect to specific  Liens,  or the perfection  thereof,
evidenced by Security  Documents covering real or personal property which by the
laws  applicable  thereto are required to be construed under the laws of another
jurisdiction.   Borrower  hereby  irrevocably  submits  itself  and  each  other
Obligated  Person to the  nonexclusive  jurisdiction  of the  state and  federal
courts of the State of Colorado.

     Section 8.6.  Limitation  on  Interest.  Lender and the  Obligated  Persons
intend to contract in strict  compliance with applicable  usury law from time to
time in effect.  In  furtherance  thereof such persons  stipulate and agree that
none of the terms and provisions  contained in the Loan Documents  shall ever be
construed to create a contract to pay, for the use,  forbearance or detention of
money,  interest in excess of the maximum  amount of  interest  permitted  to be
charged by  applicable  law from time to time in effect.  Neither any  Obligated
Person  nor any  present  or  future  guarantors,  endorsers,  or other  Persons
hereafter becoming liable for payment of any Obligation shall ever be liable for
unearned  interest  thereon or shall ever be required to pay interest thereon in
excess of the maximum amount that may be lawfully  charged under  applicable law
from time to time in effect,  and the  provisions  of this section shall control
over all other  provisions  of the Loan  Documents  which may be in  conflict or
apparent conflict herewith. Lender expressly disavows any intention to charge or
collect excessive unearned interest or finance charges in the event the maturity
of any  obligation  is  accelerated.  If (a) the maturity of any  Obligation  is
accelerated  for any reason,  (b) any  Obligation is prepaid and as a result any
amounts held to constitute  interest are determined to be in excess of the legal
maximum,  or (c)  Lender  or any other  holder of any or all of the  obligations
shall otherwise collect moneys which are determined to constitute interest which
would  otherwise  increase the interest on any or all of the  Obligations  to an
amount in excess of that  permitted  to be  charged  by  applicable  law then in
effect,  then all such sums determined to constitute  interest in excess of such
legal limit  shall,  without  penalty,  be  promptly  applied to reduce the then
outstanding  principal  of the  related  obligations  or,  at  Lender's  option,
promptly   returned  to  Borrower   or  the  other  payor   thereof   upon  such
determination.

     Section 8.7.  Severability.  If any term or provision of any Loan  Document
shall  be  determined  to be  illegal  or  unenforceable  all  other  terms  and
provisions of the Loan Documents shall  nevertheless  remain effective and shall
be enforced to the fullest extent permitted by applicable law.

     Section 8.8. Counterparts. This Agreement may be separately executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed  shall be deemed to  constitute  one and the same
Agreement.

     Section  8.9.  Conflicts.  To the  extent of any  irreconcilable  conflicts
between the  provisions of this  Agreement and the provisions of any of the Loan
Documents, the provisions of this Agreement shall prevail.

     Section 8.10.  Entire  Agreement.  This  Agreement,  the Note, the Security
Documents and the other Loan  Documents from time to time executed in connection
herewith  state the entire  agreement  between the parties  with  respect to the
subject matter hereof. Upon the repayment of any and all amounts due under or in
connection  with the Prior Credit  Agreement,  the terms and  provisions of this
Agreement shall supersede the terms and provisions of the Prior Credit Agreement
in their entirety.

     IN WITNESS WHEREOF, this Agreement is executed as of the date first written
above.
