                                 PROSPECTUS SUMMARY

      THIS SUMMARY HIGHLIGHTS THE KEY INFORMATION CONTAINED IN THIS PROSPECTUS.
BECAUSE IT IS A SUMMARY, IT DOES NOT CONTAIN ALL OF THE INFORMATION YOU SHOULD
CONSIDER BEFORE MAKING YOUR INVESTMENT DECISION. YOU SHOULD READ THE ENTIRE
PROSPECTUS CAREFULLY, INCLUDING THE SECTION TITLED "RISK FACTORS" AND THE
FINANCIAL STATEMENTS AND THE NOTES RELATING TO THOSE STATEMENTS.


                               BROOKE CORPORATION

BACKGROUND

      Brooke Corporation was incorporated in the State of Kansas in January 1986
under the name Brooke Financial Services, Inc., and in June 1987, we changed our
name to Brooke Corporation. Our principal executive offices are located at, and
our mailing address is, 10895 Grandview Drive, Suite 250, Overland Park, Kansas
66210. Our telephone number is (913) 661-0123.

OUR COMPANY

      We are an insurance agency with more than one hundred fifty (150)
franchise agents locations in thirteen states. We provide processing services,
supplier access and marketing assistance to our franchise agents through a
"master agent" program that we pioneered. Most of our revenues are derived from
the sale of property and casualty insurance policies. We also generate a
significant amount of revenues from consulting with our franchise agents and
facilitating agency acquisitions by our franchise agents. In the future, we plan
to sell financial services other than insurance, because we believe that our
franchise agents, as independent business owners, distribute financial services
less expensively than employed sales representatives since they are willing to
defer some compensation until their agency business is sold. Accordingly, we
have developed processing, lending and legal standards that we believe increase
the value and liquidity of a franchise agent's business.

THE OFFERING

      This offering includes 100,000 shares of our common stock which includes:

         o  90,000 shares of our common stock issuable upon conversion of
            100,000 shares of our Series 2002 convertible preferred stock, par
            value $25.00 per share, that are currently outstanding ("2002
            preferred stock") at a conversion ratio of one shares of our common
            stock for each one share of our 2002 $25 convertible preferred
            stock.

         o  10,000 shares of our common stock issuable upon conversion of 10,000
            shares of our Series 2002A convertible preferred stock, par value
            $25.00 per share, that are currently outstanding ("2002A preferred
            stock") at a conversion ratio of one shares of our common stock for
            each one share of our 2002A preferred stock.


                                      3

<Page>

We are not offering any shares of our preferred stock in this prospectus.

USE OF PROCEEDS

      We have previously received $2,500,000 in proceeds from the sale of our
2002 preferred stock and our 2002A preferred stock. We have invested the
proceeds from the sale of our 2002 preferred stock and 2002A preferred stock in
our wholly owned subsidiary, Brooke Credit Corporation, which has used or will
use the proceeds to repurchase some of the loans previously made by the
subsidiary and sold to participating lenders or retain some of the loans that it
expects to make in the future. We will not receive any additional proceeds from
the conversion of the convertible preferred stock into shares of our common
stock. See "USE OF PROCEEDS."

DESCRIPTION OF OUR AUTHORIZED AND OUTSTANDING CAPITAL STOCK

      Our authorized capital consists of 9,500,000 shares of common stock, par
value $1.00 per share, and 500,000 shares of our preferred stock, which are
issued with the rights, designations and preferences as set forth from time to
time by our board of directors. As of February 13, 2002, we had 692,968 shares
of common stock and 110,781 shares of convertible preferred stock issued and
outstanding. See "DESCRIPTION OF SECURITIES."

RISK FACTORS

      Your investment in the common stock offered by this prospectus involves a
high degree of risk. You should carefully review the risks described in this
prospectus. See "RISK FACTORS" for a discussion of the risks associated with
investing in the common stock.

                                 RISK FACTORS


      Your investment in our common stock involves a high degree of risk. In
addition to the other information in this prospectus, you should carefully
consider the following factors in evaluating our business and us before
purchasing the common stock. If any of the following risks or uncertainties
actually occurs, our business, financial condition and operating results would
likely suffer. In that event, you could lose all or part of the money you paid
to buy our common stock or our convertible preferred stock.

INTERNET SALES MAY ADVERSELY IMPACT INDEPENDENT PROPERTY AND CASUALTY INSURANCE
AGENTS AND RESULT IN A DECLINE IN THE DEMAND FOR OUR SERVICES.

      One of the primary markets for our services is independent property and
casualty insurance agents. The popularity of Internet sales may adversely impact
independent property and casualty insurance agents and result in a general
decline in the demand for our services. In addition, the recent enactment of the
Financial Services Modernization Act allows highly capitalized competitors, such
as banks, to offer certain insurance services, which are competitive with our
products.

OUR PROCESSING CENTER MAY BE INSUFFICIENT TO ACCOMMODATE EXPECTED GROWTH.

      Our processing services are primarily completed at a processing center
located in Phillipsburg, Kansas. The processing center's management, facilities,
and labor force may be insufficient to accommodate our expected growth. Also,
although we have safeguards for emergencies, we do not have back-up facilities
to process information if the processing center in Phillipsburg, Kansas is not
functioning. The occurrence of a major catastrophic event or other system
failure at our processing center in Phillipsburg, Kansas could interrupt
document processing or result in the loss of stored data.

OUR RELIANCE ON THE INTERNET COULD HAVE A MATERIAL ADVERSE AFFECT ON OUR
OPERATIONS AND OUR ABILITY TO MEET CUSTOMER EXPECTATIONS.

      We rely heavily on the internet in conducting our operations. A main
component of our master agent program is providing agency personnel access to
agency documents over the internet. This service requires efficient operation of
internet connections from agencies and agency personnel to our system. These
connections, in turn, depend on efficient operation of web browsers, internet
service providers and internet backbone service providers, all of which have
experienced periodic operational problems or outages in the past. Any system
delays, failures or loss of data, whatever the cause, could reduce customer
satisfaction with our services and products. Moreover, despite the
implementation of security measures, our computer system may be vulnerable to
computer viruses, program errors, attacks by third parties or similar disruptive
problems. These events could have a material adverse effect on our operations
and our ability to meet customer expectations.


                                      5

<Page>

WE HAVE GUARANTEED THE REPAYMENT OF BONDS ISSUED BY OUR SUBSIDIARY WHICH MAY
ADVERSELY AFFECT US IF OUR SUBSIDIARY INCURS SIGNIFICANT LOAN LOSSES OR ITS
ABILITY TO REPAY ITS BONDS IS OTHERWISE IMPAIRED.

      We have guaranteed the repayment of bonds issued by our finance company
subsidiary. If the finance company incurs significant loan losses or its ability
to repay the bonds is otherwise impaired, then our financial condition may be
adversely affected. In some instances, our finance company subsidiary has sold
loans to investors with full recourse which may cause an adverse financial
effect on us in the event it is required to repurchase loans of poor quality.

WE HAVE GUARANTEED SOME PAYMENTS TO AGENCY SELLERS, WHICH MAY ADVERSELY
AFFECT US.

      In connection with our activities of matching agency purchasers and
sellers, we sometimes guarantee payments to agency sellers, which may cause an
adverse financial effect on us in the event such a purchaser defaults on its
obligations to such a seller.

THE COLLATERAL FOR OUR LOANS TO AGENTS FOR THE PURPOSE OF ACQUIRING INSURANCE
AGENCIES MAY BE ADVERSELY AFFECTED BY A REDUCTION IN THE VALUE OF THE INSURANCE
AGENCY'S ASSETS.

      Through one of our subsidiaries, we make loans to agents primarily for the
purpose of insurance agency acquisition which are secured by, among other
things, insurance agency assets. Insurance agency assets in some cases are
intangible, and the value of these assets may rapidly deteriorate if borrowers
do not adequately serve their policyholders or if the policies offered are not
competitively priced. Reduction in the value of the insurance agency's assets
would result in a reduction of the value of our secured interest. This could
result in these loans being under secured which could adversely affect us in the
event of default on these loans.

WE MAY COLLECT LESS INTEREST THAN WE PAY FOR FUNDING SOME LOANS IF THROUGH OUR
SUBSIDIARY, WE REPURCHASE LOANS SOLD TO LOAN PARTICIPANTS OR MAKE ADDITIONAL
VARIABLE RATE LOANS, AND MARKET INTEREST RATES DECREASE.

      The interest rate on most of our existing loans varies annually according
to an outside index that is not controlled by us. Although most of our existing
loans have been sold to loan participants, if we repurchase these variable rate
loans or make additional variable rate loans and market interest rates decrease,
then we may collect less interest than we pay on our bonds or other funding
sources.

WE ARE DEPENDENT ON THIRD PARTIES, PARTICULARLY PROPERTY AND CASUALTY
INSURANCE COMPANIES, TO SUPPLY THE PRODUCTS SOLD BY OUR AGENTS.

      We are dependent on others, particularly property and casualty insurance
companies, to supply the products sold by our agents. A majority of our products
are supplied by five property and casualty insurance companies. Our contracts
with these suppliers can be terminated by the suppliers without cause upon
advance written notice. The loss of any one of these companies, for any reason,
would adversely affect our financial condition. While we believe we maintain
strong relationships with these companies, we can give no assurance that these
companies will not impose conditions to our relationship, such as lower
commission rates, larger premium volume requirements, or loss ratios that we
will not be able to satisfy.


                                       6

<Page>

TERMINATION OF OUR PROFESSIONAL LIABILITY INSURANCE POLICY MAY ADVERSELY
IMPACT OUR COMPANY'S FINANCIAL PROSPECTS AND OUR ABILITY TO CONTINUE OUR
RELATIONSHIPS WITH INSURANCE COMPANIES.

      Many of our insurance company contracts are contingent upon us maintaining
our professional liability insurance. Although we have an excellent claims
history and believe we have a good relationship with our professional liability
insurance carrier, if our professional liability insurance policy is terminated,
it is unlikely that we can continue our relationships with insurance companies
and therefore, the loss of our professional liability insurance policy may
adversely impact our financial prospects.

WE ARE IN A HIGHLY COMPETITIVE MARKET WHICH COULD RESULT IN REDUCED
PROFITABILITY.

      Our agents face significant competition. The popularity of internet sales
and passage of the Financial Services Modernization Act has increased the number
of potential competitors. If our prediction that agent distribution will become
more widespread is accurate, then we will face greater competition for the
services we provide to our agents. Many of our potential competitors have
greater financial resources and market acceptance.

WE ARE DEPENDENT ON KEY PERSONNEL.

      We are dependent upon the continued services of senior management,
particularly the services of Robert D. Orr, Leland G. Orr and Michael Hess. The
loss of the services of any of these key personnel, by termination, death or
disability, could have a material adverse effect on us.

WE ARE UNDER COMMON CONTROL WITH OUR AFFILIATED COMPANIES WHICH COULD RESULT IN
CONFLICTS OF INTEREST.

      Through their ownership in Brooke Holdings, Inc., Robert D. Orr, Leland G.
Orr and Michael Hess control all aspects of Brooke Corporation and, even if all
shares of our preferred stock are converted into shares of common stock, those
individuals will still be in a position to elect all of our directors. A common
management group directs the activities of the companies in the affiliated
group. As a result of these affiliated relationships, conflicts of interests may
exist or may arise in the future. In addition, some of our business transactions
with our affiliates were not negotiated through independent arms-length
negotiations. We can give no assurance that any conflicts which arise will be
resolved in our best interests. In addition, we can give no assurance that there
are not now, or may in the future, be unrelated businesses that might be able to
provide similar services to us in a more efficient, competent and less costly
manner, or that our affiliates will be able to continue to provide services to
us. In the event that one of our affiliates is not able to perform its services,
we can give no assurance that a suitable replacement can be located without
incurring substantial expense, or that any replacement will provide an
acceptable quality of services to us.


                                       7

<Page>

WE COULD BE ADVERSELY AFFECTED IF WE FAIL TO COMPLY WITH GOVERNMENT REGULATIONS.

      Our activities are subject to comprehensive regulation in the various
states in which we do business. Our success will depend in part upon our ability
to satisfy such regulations and to obtain and maintain all required licenses and
permits.

      Although we believe that we are currently in compliance with statutes and
regulations applicable to our business, there can be no assurance that we will
be able to maintain compliance without incurring significant expense. Our
failure to comply with any current or subsequently enacted statutes and
regulations could have a material adverse effect on us. Furthermore, the
adoption of additional statutes and regulations, changes in the interpretation
and enforcement of current statutes and regulations, or the expansion of our
business into jurisdictions that have adopted more stringent regulatory
requirements than those in which we currently conduct business could have a
material adverse effect on us.

WE HAVE NO RESTRICTION ON OUR ABILITY TO INCUR ADDITIONAL DEBT.

      We are not restricted in our ability to incur debt. Any of our debt would
be senior in right of payment to our preferred stock and our common stock.
Further, we do not have any limitation on the amount or percentage of
indebtedness that we may incur. In addition, because we intend to expand our
business, we may require additional capital or other funds for the expansion of
our operations. We may obtain these funds through the sale of debt securities on
terms we cannot now predict.

WE MAY BE UNABLE TO MEET OUR ONGOING NEEDS FOR ADDITIONAL CAPITAL

      We cannot accurately predict how much money we will need to implement our
strategic business plan or to continue operations. Our future capital
requirements, the likelihood that we can obtain money and the terms of any
financing will be influenced by many different factors, including:

          o   our revenues;

          o   the status of competitors in the marketplace;

          o   our performance in the marketplace;

          o   our overall financial condition;

          o   our business prospects; and

          o   the perception of our growth potential by the public, including
              potential lenders.

      If we cannot obtain adequate financing or if the terms on which we are
able to acquire financing are unfavorable, our business and financial condition
could be negatively affected.


                                       8
<Page>

NO MARKET EXISTS FOR OUR COMMON STOCK

      No public market exists to trade the common stock offered by this
prospectus and we do not intend to have the common stock listed on any
national securities exchange or quoted through the NASDAQ automated quotation
system. We cannot assure you that there will be a market to sell the common
stock, or the price at which you would be able to sell your common stock. The
price that you would be able to obtain depends on many factors, including our
operating results and the market for similar securities.

STATE BLUE SKY LAWS MAY PREVENT SALES OF COMMON STOCK

      Before we or you can sell any common stock to a purchaser, state
securities laws require that the securities be registered or qualified for
sale in the state where the purchaser resides, or else fall within an
exemption from registration. We will not knowingly sell the common stock to
purchasers in jurisdictions in which the common stock is not registered or
otherwise qualified for sale or exempt. However, there is a risk that
purchasers may buy the common stock in the after-market or may move to
jurisdictions in which the common stock are not registered, qualified, or
exempt. We cannot guarantee that any purchaser will be able to effect any
required registration or qualification.

THIS OFFERING AND THE SALE OR EXERCISE OF OUR EXISTING SECURITIES COULD CAUSE
DILUTION OF EXISTING HOLDERS OF THE COMMON STOCK BY DECREASING THE PRICE OF
OUR COMMON STOCK

      The market price of the common stock could be adversely affected by
sales of substantial amounts of common stock in the public market after this
offering, by the perception that those types of sales could occur or by the
fact or perception of events which would have a dilutive effect on the market
for the common stock.

WE COULD ISSUE PREFERRED  STOCK THAT COULD ADVERSELY  EFFECT THE RIGHTS OF
THE COMMON STOCK HOLDERS

      Our articles of incorporation gives our board of directors the authority
to issue preferred stock without approval of our stockholders. We may issue
preferred stock to finance our operations. We may authorize the issuance of our
preferred stock in one or more series. In addition, we may set several of the
terms of the preferred stock, including:

      o   dividend and liquidation preferences,

      o   voting rights,

      o   conversion privileges,

      o   redemption terms, and

      o   other privileges and rights of the shares of each authorized series of
          preferred stock.

      The issuance of large blocks of preferred stock could have a dilutive
effect on our existing shareholders and it can negatively impact our existing
stockholders' liquidation


                                       9

preferences. In addition, while we include preferred stock in our
capitalization to improve our financial flexibility, we could possibly issue
or preferred stock to third parties as a method of discouraging, delaying or
preventing a change in control in our present management or we could issue
preferred stock that has disproportionate voting rights.

      Our board of directors could use its authority to issue preferred stock
without action by the holders of the common stock to discourage attempts by
others to obtain control of our company through a merger, tender offer, proxy
or consent solicitation, or otherwise, by making such attempts more difficult
to achieve and more costly. Our board of directors also may issue preferred
stock with voting rights that could adversely affect the voting power of the
then-existing holders of common stock.

                                USE OF PROCEEDS

      We previously received $2,500,000 in proceeds from the sale of 90,000
shares of our 2002 preferred stock and 10,000 shares of our 2002A preferred
stock to investors. We have invested the proceeds from the sale of our 2002
preferred stock and 2002A preferred stock in our wholly owned subsidiary,
Brooke Credit Corporation, which has used or will use the proceeds to
repurchase some of the loans previously made by the subsidiary and sold to
participating lenders or retain some of the loans that it expects to make in
the future. We will not receive any additional proceeds from the conversion
of the convertible preferred stock into shares of our common stock.

                           DESCRIPTION OF THE COMPANY

BACKGROUND

      Brooke Corporation was incorporated in the State of Kansas in January 1986
under the name Brooke Financial Services, Inc., and in June 1987, we changed our
name to Brooke Corporation. Our principal executive offices are located at, and
our mailing address is, 10895 Grandview Drive, Suite 250, Overland Park, Kansas
66210. Our telephone number is (913) 661-0123. We are controlled by Brooke
Holdings, Inc., which owns 511,701 shares of our common stock representing
approximately 73.84% of our outstanding common stock as of February 4, 2002.

OUR COMPANY

      We are an insurance agency with more than one hundred fifty (150)
franchise agents locations in thirteen states. We provide processing services,
supplier access and marketing assistance to our franchise agents through a
"master agent" program that we pioneered. Most of our revenues are derived from
the sale of property and casualty insurance policies. We also generate a
significant amount of revenues from consulting with our franchise agents and
facilitating agency acquisitions by our franchise agents. In the future, we plan
to sell financial


                                       10

<Page>

services other than insurance, because we believe that our franchise agents,
as independent business owners, distribute financial services less
expensively than employed sales representatives since they are willing to
defer some compensation until their agency business is sold. Accordingly, we
have developed processing, lending and legal standards that we believe
increase the value and liquidity of a franchise agent's business.

      We are engaged in the business of selling insurance and financial
services through independent agents and brokers. Virtually all of our current
revenues are derived from the sale of property and casualty insurance
policies, although we intend to increasingly sell other insurance and
financial services, including life and health insurance, credit services,
investment services and other related financial services.

      We provide third-party administration (processing) to independent
insurance agents and bank insurance agents using the "master agent" program
pioneered by us. The basic premise of our master agent program is the concept
that agents must outsource administrative activities to a master agent that
can generate sufficient economies of scale to reduce administrative expenses
and increase agent productivity. As such, we have developed detailed
processing standards for third-party processing by a master agent.
Administrative and processing services provided by us to the agents under the
master agent program include, but are not limited to, accounting, data
maintenance and payment services.

      In connection with the master agent program, we prepare, reconcile and
distribute monthly statements to each of our franchise agents. Such monthly
statements list all credits and debits and represent a comprehensive
reconciliation of our commissions, receipts from agent's customers, checks
issued to an agent's customer and vendors, and pass-through or journal
entries for amounts due in our capacity as master agent.

      The master agent program also promotes agency efficiency through data
maintenance services. All customer account documents are provided to us for
imaging or other electronic storage. Agents are then provided passwords so
documents associated with an agency may be viewed by such agency's personnel
from any location via the internet.

      In addition, we provide marketing assistance to our network of agents
through brand name development. By participating in the master agent program,
agents gain the power of a common brand name through us. We believe that
associating products and services with a trusted brand name can result in
additional sales, much as additional sales can result from a product
endorsement. Although a trusted brand name may attract an internet customer,
because of the complexity of many insurance products and financial services,
the assistance of a local agent to provide individualized customer support is
often required. We believe that agents with a trusted brand name, local
agency presence and master agent support are well-positioned in
business-to-business internet sales of insurance and financial services.

      Another aspect of the master agent program that is advantageous to the
agents is our purchasing power. By consolidating purchasing activities, we
believe that a master agent is able to negotiate better commissions and has
access to more insurance companies.


                                     11

      Through our subsidiary, Brooke Credit Corporation, we also provide
loans to independent insurance agents for acquisition of insurance agencies,
matches agency buyers with sellers, inspects agency assets for prospective
agency purchasers and generally assists agents with increasing agency value
and liquidity. We believe that independent insurance agents, as small
business owners, distribute financial services less expensively because they
are more motivated and willing to defer some of their compensation until the
agency business is sold. Therefore, as part of the effort to make agents more
efficient, we attempt to make ownership more attractive by facilitating
ownership transfers through development of detailed legal standards,
increasing credit availability by developing agency lending standards, and
making ownership value easier to measure with standards for appraisals for
insurance agencies.

BUSINESS STRATEGY

      We believe that independent insurance agencies represent an
increasingly popular means for distributing certain financial services and
that our master agent concept will become increasingly important to the
future success of independent insurance agents. As such, we expect the demand
for our processing, marketing and lending services to grow rapidly.

      During the second calendar quarter of 2001, we introduced a specialty
program to provide prospective agency buyers with assistance in inspecting
agency assets to be purchased and assistance with agency cash flow
management, marketing, and operations during the first year following an
acquisition. During the first quarter of 2002, we intend to introduce another
specialty program primarily designed to assist agency sellers in finding
agency buyers, or


                                      13

<Page>

alternatively, assisting agency buyers find agencies to purchase. Finally, in
the first quarter of 2002, we intend to acquire a bank in order to commence
the distribution of bank products and services through our franchise agents.
We are using our existing management and staff to deliver these products;
however, as product demand increases, additional management and staff may be
required. We do not expect to develop any other new products during 2002,
because demand for existing products and the products added during the first
quarter is anticipated to fully utilize our management and staff. However, we
still expect to revise or enhance our existing products upon receipt of agent
comments and suggestions that we believe are beneficial to our operations.

operations during the first year following an acquisition. We are using our
existing management and staff to deliver this product; however, as product

and suggestions deemed beneficial to our operations.

SERVICES AND PRODUCTS

      We have two product lines, the first of which is the master agent
program, which was developed exclusively by us and to which we believe is
unique to the industry. Our secondary line of products is specialty programs,
such as our agency lending program and insurance programs for industry
niches, which are offered through various subsidiaries.

      Document management and commissions accounting are an agency's primary
administrative functions and may be outsourced to our processing center as
part of the services offered through the master agent program. Documents and
accounting information are presented to the agents by the processing center
through the processing center's web site at WWW.BROOKEPROCESSING.COM (the
contents of which are not incorporated by reference into this prospectus).
The master agent program also provides for development of a national brand
name for agents and consolidation of agent's purchasing power with insurance
companies and other financial services suppliers.

      Our secondary product line is specialty programs, the most successful
of which is the lending program, but also includes insurance programs for
various industry niches, which are offered through various subsidiaries.

      We, through our subsidiary Brooke Credit Corporation, originate loans
to agents primarily for the purpose of insurance agency acquisition. Such
loans are secured by, among other things, insurance agency assets. Our
lending program features standardized legal documentation and established
standards for credit approval and ongoing credit review.


                                       14

<Page>

      The origination of agency acquisition loans to agents is expected to
increase demand for our master agent services. We believe that many
traditional lenders are reluctant to lend money for acquisition of an
insurance agency because the primary collateral for such loans, insurance
commissions, could be jeopardized in the event of a borrower default. To
protect itself from such a risk, we require all borrowers to enroll in the
master agent program. Under the master agent program, we are listed as the
agent-of-record for policies written by an agent. Thus, in the event that the
agent/borrower defaults on its obligations under the agency acquisition loan,
we continue to collect payments and service the defaulted agent's accounts.
This arrangement minimizes the impact of an agent/borrower's default and
protects the collateral pledged under the terms of the agency acquisition
loan.

      In addition to our lending program, we, through our wholly-owned
subsidiaries, The American Agency, Inc., The American Heritage, Inc., and
Interstate Insurance Group, L.L.C., sell insurance programs and "targeted
market" policies through our network of agents and through agents not
affiliated with us. In connection with such specialty programs, agents offer
insurance coverage to targeted classes of business which may not be obtained
from standard markets at all or which cannot be obtained from standard
markets on a favorable basis. These target classes of business include
limousine companies and meat processors. Although specialty programs may be
offered through any duly licensed agent, it is typical for specialty programs
to be "cross sold" to agents that purchase the master agent services. In
addition, we offer our buyers' assistance specialty program through The
American Heritage, Inc. to assist prospective agency buyers with their
inspection of assets to be acquired and to assist new owners with agency cash
flow management, marketing, and operations during the first year following an
acquisition. We intend to offer our agency listing specialty program through
The American Agency, Inc. to assist prospective agency sellers in finding
agency buyers and prospective agency buyers in finding agencies to purchase.
Finally, we intend to offer bank products and services of an indirect wholly
owned bank subsidiary through its franchise agents.

      A typical transaction occurs when an insurance policy is sold by one of
our agents and the premium is paid by the customer directly to an insurance
company. On a periodic (usually monthly) basis, insurance companies pay
commissions to us for the sale of insurance policies which we record as
commission income. We then pay a share of sales commissions to our agents
which we record as commission expense.

     We are solely responsible for payment to insurance companies of premiums
collected from customers for the sale of insurance policies even if its
agents mishandle premium collection. Accordingly, we are the recipient and
owner of all commissions paid by insurance companies resulting from the sale
of insurance policies by our agents. Our agents have an exclusive contractual
relationship with us and generally do not have any contractual relationship
with the insurance companies. As such, payment of a share of sales
commissions to the agents is our obligation and is not an obligation of any
insurance company. Furthermore, for income tax purposes, we are required to
record all commissions received from insurance companies as income and
correspondingly report to the appropriate tax authorities all commissions
expense paid to agents.

      Commission expenses as a percentage of commission income has increased
from 55% in 1998 to 64% in 1999 to 70% in 2000 and to 75% for the first nine
months of 2001, primarily as a


                                       15

<Page>

result of the following: (i) we have gradually increased the share of sales
commissions paid to agents during the last several years, and it is our plan
to pay an increasing share of sales commissions to our agents as we grow and
marginal expenses decrease from economies of scale; and (ii), our commissions
from the sale of policies by The American Agency, Inc. have decreased as a
result of the discontinuance of one of The American Agency Inc.'s specialty
insurance programs. The ratio of commission expense to commission income for
insurance programs or "targeted market" insurance policies is generally less
than from the sale of other insurance policies.

      The typical transaction outlined above provides for the billing and
collection of premiums directly by insurance companies because our agents are
required to use direct insurance company billing when available. However, in
those instances where direct company billing is not available, we are
responsible to the insurance company for billing and collecting the full
premium from customers. We then remit to insurance companies the amount of
the customer's premiums, net of sales commissions, when we are billed by
insurance companies. As a result, we record an account receivable for the
amount owed by the customer to us and simultaneously record a payable for the
amount owed by us to the related insurance company.

      Customer receivables are included in the balance sheet category for
accounts and notes receivable. This category also includes receivables from
insurance companies for commissions on direct company billed policies, profit
sharing commissions and certain notes receivables held by our finance company
subsidiary. Customer receivables result when we assume responsibility for the
billing and collection of premiums that is typically the responsibility of
the insurance companies. To accommodate customers when direct company billing
is not available, we sometimes permit flexible premium payments by not
requiring full premium payment prior to policy delivery. This resembles the
premium payment flexibility offered by insurance companies when premiums are
direct company billed. The consequences of providing this flexibility include
collection risk and reduced cash balances from payment of premiums to
insurance companies prior to premium collection from customers.

CUSTOMERS

      Our customers are independent insurance agents and bank insurance
agents. We currently sell our products and services through over 150 agencies
that employ or retain over 375 agents in the States of Arizona, Colorado,
Florida, Illinois, Iowa, Kansas, Louisiana, Missouri, Nebraska, Nevada,
Oklahoma, Texas, and Utah.

      It has been our experience that independent insurance agents are more
willing to sell their agency businesses. Brooke Credit Corporation's lending
program is a source of credit for prospective purchasers of agency
businesses. The relative success of our agency lending program is
attributable to the loan collateral enhancements and protections provided by
our master agent concept. As such, we expect that as the demand for agency
acquisition loans from independent insurance agents increases, the demand for
our master agent services will increase as well.

      Although a significant number of our current customers are bank insurance
agents, such agents represent a relatively small portion of our overall
commissions because they are generally


                                       16

<Page>

agents from small banks in small communities. With the passage of the
Financial Services Modernization Act, larger banks in larger communities are
now authorized to sell insurance. We anticipate that larger banks will engage
in the business of selling insurance, which, in turn, we believe will lead to
a greater demand for the services offered under our master agent program. By
outsourcing agency administration to a master agent and with the purchasing
power provided by a master agent, we believe that bank insurance agents can
immediately take advantage of the expanded insurance powers available under
the Financial Services Modernization Act.

INSURANCE MARKET

      Although our revenues are comprised primarily of the sales commission
portion of insurance premiums, most industry analysis is based on premiums.
Based on typical sales commission rates, we have estimated our gross
annualized premiums to be approximately $175 million to approximately $200
million for the year 2001. According to the Insurance Information Institute,
insurance premiums in the United States totaled approximately $735 billion in
2001, which was 8.5% more than in 1999. Premiums in the property and casualty
sector totaled approximately $299.6 billion and life and health premiums
totaled approximately $435.4 billion. Our agents sell insurance to both
personal and commercial customers; however, as a group, the agents sell more
commercial insurance than personal insurance.

COMPETITION

      We are unaware of any direct competitors in the United States for the
master agent services that are offered to independent insurance agents and
bank insurance agents. Although we are aware of other insurance companies
that offer similar services to agents, to the best of our knowledge, such
services do not allow agents exclusive agency ownership and/or require that
such agents sell exclusively for one insurance company. Also, insurance
companies sometimes offer assistance to agents' policyholders that have
purchased policies from their specific insurance company. However, there does
not appear to be a service, such as our master agent program, that attempts
to provide a comprehensive solution to the efficiency problems encountered by
independent insurance agents and bank insurance agents.

      We have more competition for the sale of its specialty programs,
especially insurance programs, than we do for the sale of our master agent
services. Many independent insurance agents and brokers are developing
insurance programs for specific market niches. However, those that purchase
our master agent services are a receptive audience for our specialty programs
which we believe gives us a significant advantage within our master agent
organization.

      The competition for agency loans comes primarily from banks and other
traditional lenders, many of which are larger and have larger resources than
us. However, we are not aware of any lenders that have developed the
comprehensive legal and lending standards that are required to protect and
preserve the intangible assets that serve as collateral for insurance agency
loans. Additionally, as previously noted, the master agent program is
critical to collateral preservation and we believe that the entire package of
services offered under the master agent program are not currently available
from others.


                                       17

SALES AND MARKETING

      Most of our marketing activities are currently conducted from our
Kansas City, Kansas, Dallas, Texas or Denver, Colorado, area regional
offices. We opened an additional regional office in Nashville, Tennessee in
the fourth quarter of 2000.

      Our regional managers market the master agent program to independent
insurance agents using a description of "franchise agents" because, as a part
of the master agent program, independent insurance agents use a common trade
name and share many other characteristics of a franchise relationship.
Accordingly, we disclose information relating to the master agent program to
prospective agents using the Uniform Franchise Offering Circular format.

      The services offered under our master agent program are also marketed
to bank insurance agents; however, bank insurance agents typically use a
trade name associated with the sponsoring bank instead of the common trade
name used by franchise agents. Therefore, the term "bank agents" is used to
differentiate franchise agents from bank agents. Unlike franchise agents, the
services offered under the master agent program to bank agents are limited to
insurance, as most bank agents also want to sell the banking, investment or
lending services of the sponsoring bank.

      Those agents selling our specialty programs are identified as "broker
agents." Broker agents provide expertise in a specific industry niche to
other agents, typically franchise or bank agents that purchase our master
agent services. Additional revenues are created when our franchise agents or
bank agents purchase expertise from our broker agents. For example, our
agency lending program requires enrollment in the master agent program and,
as a result, is the largest source of master agent program sales.

      In the spirit of multilevel sales organizations, we encourage our
franchise, bank and broker agents to recruit subagents to purchase the
services offered under the master agent program and specialty programs.
Franchise agents can build a sales organization of smaller subagents and,
because of growth and size bonuses, receive a larger share of commissions
from us. Correspondingly, bank agents can use the master agent's services to
recruit other banks as subagents.

EMPLOYEES

      We currently employ a total of approximately 141 employees of which a
significant number are part time and temporary employees employed by the
processing center. On a full-time equivalency basis (those employees who
regularly work 37.5 hours or more per week), we employ approximately 70
individuals.

SUPPLIERS

      We have agency relationships with a large number of insurance
companies. We have direct agency relationships with five of the six leading
writers of commercial insurance in the United States (based on 1998
premiums). Our largest suppliers include Safeco Insurance Company, Allied
Insurance Company, Employers Mutual Companies, Columbia Insurance Company and
Allstate Insurance Company.

GOVERNMENT REGULATION

      Our insurance activities are generally regulated by the insurance
departments of individual states. We must maintain valid insurance agency
licenses in most of the states in which we transact our insurance and
financial services business. Periodically, agency insurance licenses must be
renewed by and license fees must be remitted to the individual states.

      Our lending programs are targeted to businesses and are generally
unregulated. Although we do not typically make consumer loans, our finance
company subsidiary is licensed as a consumer finance company by the States of
Kansas and Nebraska. Our franchising activities are also regulated, to a
certain extent, by the Federal Trade Commission and state regulators. Our
banking activities will be regulated by the Federal Reserve and the Kansas
Banking Department. As a reporting company, our reporting activities are
regulated by the Securities and Exchange Commission. Offering of our
securities are subject to regulations promulgated by the Office of the
Securities Commissioner of the State of Kansas. We believe that we are
currently in compliance with all state and federal regulations to which we
are subject.

                       DETERMINATION OF THE OFFERING PRICE

      There is no established public market for the shares of common stock
being registered pursuant to this prospectus. The 2002 preferred stock and
the 2002A convertible preferred stock have been sold from time to time by us,
and at those times, we set the rate at which shares of our preferred stock
could be converted into shares of our common stock based on multiple factors.
The conversion prices do not necessarily bear any relationship to our assets,
book value, or other investment criteria, and you should not be consider it
an indication of the actual value of our securities. If a public market for
our shares were to develop or if we were to merge with another company, the
public market price or the merger price for our shares could be substantially
less than the conversion price.

                            DESCRIPTION OF SECURITIES

      Our authorized capital stock consists of 10,000,000 shares, which shall
consist of 9,500,000 shares of our common stock, par value $1.00 per share,
and a total of 500,000 shares of our preferred stock. As of February 13,
2002, we had 692,968 shares of common stock and 110,781 shares of convertible
preferred stock issued and outstanding, including 110,000 shares of preferred
stock which, if converted into shares of common stock would total 110,000
shares of common stock. Overall, we would have a total of 802,968 shares of
common stock issued and outstanding if all of our outstanding convertible
securities are exercised and converted into common stock.

COMMON STOCK

      Each share of common stock is entitled to one vote on each matter
submitted to a vote of the stockholders and is equal to each other share with
respect to voting, liquidation and dividend rights. Holders of the common
stock are entitled to receive the dividends, if any, as may be declared by
the Board of Directors out of assets legally available for dividend
distributions and to receive net assets in liquidation after payment of all
amounts due to creditors and any


                                       19

<Page>

liquidation preference due to preferred stockholders. The common stock does
not have cumulative voting rights in the election of directors.

      Common stockholders were paid dividends in the amount of $.06 per share
for the periods ending March 31, 2001, June 30, 2001 and September 30, 2001.

      There is no market for the common stock offered by this prospectus, the
common stock is not listed on a securities exchange.

      As of February 4, 2002, there were 209 holders of record of our 692,968
outstanding shares of common stock. Based upon information provided to us by
persons holding securities for the benefit of others, it is estimated that we
have in excess of 200 beneficial owners of our common stock as of February 4,
2002.

PREFERRED STOCK

      For a complete description of the terms and conditions of each series
of our preferred stock, please refer to our Articles of Incorporation, which
is filed as an exhibit to the registration statement. The descriptions of the
series of our preferred stock in this prospectus that follow are qualified in
their entirety by reference to that exhibit.

      Our board of directors has the authority to issue up to 500,000 shares
of our preferred stock. Our board of directors may issue our preferred stock
in one or more series and fix the relative rights of those series without any
further vote or action by the holders of our common stock or our preferred
stock. Our board of directors has designated (a) 1,000 shares as convertible
preferred stock, par value $75.00 per share (the "original preferred stock");
(b) 100,000 shares as Series 2002 convertible preferred stock, par value
$25.00 per share (the "2002 preferred stock"); (c) 10,000 shares as Series
2002A convertible preferred stock, par value $25.00 per share (the "2002A
preferred stock"); and (d) 40,000 shares as Series 2002B convertible
preferred stock, par value $32.00 per share (the "2002B preferred stock").
The remaining 349,000 shares of preferred stock remain undesignated, for
which the designations, preferences, conversion rights, and cumulative,
relative, participating, optional or other rights, including voting rights,
qualifications, limitations or restrictions thereof, may be determined by our
board of directors on some future date without any further authorization by
our shareholders.

      As of February 4, 2002, we had 781 shares of our original preferred
stock, 100,000 shares of our 2002 preferred stock, 10,000 shares of our 2002A
preferred stock and no shares of our 2002B preferred stock outstanding.
Currently there exists no public market for our preferred stock and no
assurances can be given that a public market will develop in the future.

ORIGINAL PREFERRED STOCK

      VOTING RIGHTS; CONSENT

      The original preferred stock has no voting rights. However, we must
obtain the consent of a majority of the outstanding shares of original
preferred stock before we can (a) create or authorize any shares or series of
shares ranking prior to or on a parity with the original preferred stock; or
(b) amend, alter or repeal any of the express terms of the original preferred
stock.

      DIVIDENDS

      The holders of original preferred stock are entitled to receive a
quarterly non-cumulative cash dividend of 9% per annum, out of funds at the
time legally available for payments of dividends under the General Business
Corporation Act of Kansas. Original preferred stockholders were paid
dividends in the amount of $1.6875 per share for the periods ending March 31,
2001, June 30, 2001, September 30, 2001 and December 31, 2001.

      CONVERSION INTO COMMON STOCK

      Each share of original preferred stock is convertible by the holder
into shares of our common stock, and each share of original preferred stock
shall be exchanged for 13 shares of our common stock, which occurs upon
delivery of written notice by the holder of the original preferred stock to
us of such conversion.

      ANTI-DILUTION PROVISIONS

      We are required to adjust the conversion ratio described in
"--Conversion into Common Stock" to avoid dilution caused by any of the
following events:

         o  we issue our common stock for a price per share less than the
            current fair market value

         o  we issue rights or options to purchase our common stock or issuance
            of securities convertible into shares of our common stock where the
            exercise or conversion price is less then the fair market value of
            such shares

         o  stock dividends

         o  stock splits

      REDEMPTION

      We may redeem each share of the original preferred stock at our option at
a redemption price of $75.00 per share if we deliver to the holders of the
original preferred stock 30 days prior written notice. Holders of the original
preferred stock may still convert their shares to shares of our common stock
prior to the end of the 30-day period.

      LIQUIDATION OR DISSOLUTION

      If we are liquidated or dissolved, the holders of the original
preferred stock are entitled to a liquidation preference of $75.00 per share
before any amounts shall be paid to the holders of the 2002 preferred stock,
our 2002A preferred stock, our 2002B preferred stock, our preferred stock
that is currently undesignated and our common stock. The only payment to the
original preferred stock is the liquidation preference, as the remaining
assets are divided between our other securityholders.

2002 PREFERRED STOCK

      VOTING RIGHTS; CONSENT

      The 2002 preferred stock has no voting rights. However, we must obtain
the consent of a majority of the outstanding shares of the 2002 preferred
stock before we can (a) create or authorize any shares or series of shares
ranking prior to or on a parity with the 2002 preferred stock; or (b) amend,
alter or repeal any of the express terms of the 2002 preferred stock.

      DIVIDENDS

      The holders of the 2002 preferred stock are entitled to receive a
quarterly cumulative cash dividend of 10% per annum, out of funds at the time
legally available for payments of dividends under the General Business
Corporation Act of Kansas. The dividend payment is made after any dividend is
paid to the original preferred stock for the current fiscal year. Holders of
2002 preferred stock were paid dividends in the amount of $.625 per share for
the periods ending March 31, 2001, June 30, 2001, September 30, 2001 and
December 31, 2001.

      SUBORDINATION

      The rights of the holders of the 2002 preferred stock are subordinate
to the rights of the holders of the original preferred stock except to the
extent that holders of the 2002 preferred stock are entitled to cumulative
dividends and the holders of original preferred stock are not entitled to
cumulative dividends.

      CONVERSION INTO COMMON STOCK

      On or prior to April 1, 2002, each one share of the 2002 preferred
stock is convertible by the holder into one share of our common stock, which
occurs upon delivery of written notice by the holder of the 2002 preferred
stock to us of such conversion.

      ANTI-DILUTION PROVISIONS

      On or prior to April 1, 2002, we are required to adjust the conversion
ratio described in "--Conversion into Common Stock" to avoid dilution caused
by any of the following events:

         o  we issue our common stock for a price per share less than the
            current fair market value

         o  we issue rights or options to purchase our common stock or issuance
            of securities convertible into shares of our common stock where the
            exercise or conversion price is less then the fair market value of
            such shares

         o  stock dividends

         o  stock splits

      REDEMPTION

      We may redeem each share of the 2002 preferred stock at our option at a
redemption price of $27.50 per share on any dividend payment date.

      LIQUIDATION OR DISSOLUTION

      If we are liquidated or dissolved, the holders of the 2002 preferred
stock are entitled to a liquidation preference of $25.00 per share after
amounts are paid to the holders of our original preferred stock and before
any amounts shall be paid to the holders of our 2002A preferred stock, our
2002B preferred stock, our preferred stock that is currently undesignated and
our common stock. The only payment to the 2002 preferred stock is the
liquidation preference, as the remaining assets are divided between our other
securityholders.

2002A PREFERRED STOCK

      Our 2002A preferred stock has all of the same rights as our 2002
preferred stock set forth above under "Preferred Stock--2002 Preferred
Stock," except that the rights of the holders of the Series 2002A preferred
stock subordinate to both the original preferred stock and the 2002 preferred
stock, including in payment of dividends and upon liquidation or dissolution.

                              PLAN OF DISTRIBUTION

      We previously sold the 2002 preferred stock and the 2002A preferred
stock in intra-state offerings registered with the Office of the Kansas
Securities Commission in transactions exempt from registration under the
Securities Act of 1933, as amended. The shares of common stock offered in
this prospectus are issuable upon conversion of the shares of the 2002
preferred stock and 2002A preferred stock.

      No underwriter, broker, dealer or agent has been engaged by us in
connection with the distribution of the common stock upon conversion of
preferred stock.

      Any common stock covered by this prospectus which qualifies for sale
based on Rule 144 under the Securities Act of 1933, as amended may be sold
under Rule 144 rather than based on this prospectus. There is no assurance
that the holders of the common stock will sell any or all of the common
stock. The holders of the common stock may transfer, devise or gift common
stock by other means not described herein.

                                  LEGAL MATTERS

      Matters relating to the legality of the securities to be offered by
this prospectus will be passed upon for us by the law firm of Kutak Rock LLP,
Denver, Colorado.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Section 17-6305 of the Kansas General Corporate Law provides generally
and in pertinent part that a Kansas corporation may indemnify its directors,
officers, employees or agents against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably
incurred by them in connection with any civil suit or action, except actions
by or in the right of the corporation, or any administrative or investigative
proceeding if, in connection with the matters in issue, they acted in good
faith and in a manner they reasonably believed to be in, or not opposed to,
the best interests of the corporation, and in connection with any criminal
suit or proceeding, if in connection with the matters in issue, they had no
reasonable cause to believe their conduct was unlawful. Section 17-6305
further provides that in connection with the defense or settlement of any
action by or in the right of the corporation, a Kansas corporation may
indemnify its directors, officers, and employees against expenses actually
and reasonably incurred by them in connection with the defense or settlement
of the action or suit if they acted in good faith and in a manner they
reasonably believed to be in, or not opposed to, the best interests of the
corporation.

      Article VIII of the Amendment and Restatement to the Articles of
Incorporation of the registrant requires the registrant to indemnify its
directors, officers, employees and agents to the maximum extent and in
accordance with the provisions of the Kansas General Corporation Law.

ITEM 17.  UNDERTAKINGS
      (a) The undersigned registrant will:

            (i) File, during any period in which it offers or sells securities,
      a post-effective amendment to this registration statement to:

                  (1) include any prospectus required by section 10(a)(3) of
            the Securities Act of 1933, as amended (the "Securities Act");

                  (2) reflect in the prospectus any facts or events which,
            individually or together, represent a fundamental change in the
            information in the registration statement; and notwithstanding the
            forgoing, any increase or decrease in volume of securities offered
            (if the total dollar value of securities offered


                                      II-2

<Page>

            (if the total dollar value of securities offered would not exceed
            that which was registered) and any deviation from the low or high
            end of the estimated maximum offering range may be reflected in the
            form of prospects filed with the Commission pursuant to Rule 424(b)
            if, in the aggregate, the changes in the volume and price represent
            no more than a 20% change in the maximum aggregate offering price
            set forth in the "Calculation of Registration Fee" table in the
            effective registration statement;

                  (3) include any additional or changed  material  information
            on the plan of distribution.

            (ii) For determining liability under the Securities Act, treat each
      post-effective amendment as a new registration statement of the securities
      offered, and the offering of the securities at that time to be the initial
      bona fide offering.

            (iii) File a post-effective amendment to remove from registration
      any of the securities that remain unsold at the end of the offering.

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

      (c) Insofar as indemnification for liabilities arising under the
Securities Act 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
Securities 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
Securities Act and will be governed by the final adjudication of such issue.
