                                EXPLANATORY NOTE

   Gold Banc Corporation, Inc. (the "Registrant") hereby amends its
Registration Statement on Form S-4 (File No. 333-65539) (the "Form S-4"), by
filing this Post-Effective Amendment No. 2 on Form S-3 to the Form S-4 relating
to 3,920,292 shares of the Registrant's common stock, par value $1.00. All
shares covered hereby were received by the former stockholders of Citizens
Bancorporation, Inc. (the "Selling Stockholders") in connection with the merger
of Citizens with and into a wholly-owned subsidiary of the Registrant. Such
shares were previously registered on the Form S-4 and are being transferred to
this Post-Effective Amendment No. 2 on Form S-3 to the Form S-4 pursuant to the
provisions of Rule 401(e) and the procedure described therein. All filing fees
payable in connection with the registration of these securities were previously
paid by the Registrant in connection with the filing of the Form S-4.

   This Registration Statement contains two forms of prospectus. One prospectus
will be used in connection with an underwritten offering of 751,045 shares
(plus up to 112,655 shares covered by the underwriter's over-allotment option)
by certain Selling Stockholders (the "Underwritten Prospectus") and one to be
used in connection with a non-underwritten offering of up to 3,056,592 shares
from time to time by the remaining Selling Stockholders (the "Non-Underwritten
Prospectus"). The Underwritten Prospectus and the Non-Underwritten Prospectus
will be identical in all respects except that they will contain different front
and back cover pages and different information appearing under the following
headings:

  . Prospectus Summary--The Offering;

  . Selling Stockholders;

  . Underwriting (replaced by Plan of Distribution in the Non-Underwritten
    Prospectus); and

  . Legal Matters.

   The Underwritten Prospectus is included herein and is followed by those
pages to be used in the Non-Underwritten Prospectus which differ from those in
the Underwritten Prospectus. Each of the pages for the Non-Underwritten
Prospectus included herein are labeled "Alternate Page for Non-Underwritten
Prospectus."

                               PROSPECTUS SUMMARY

   This summary does not contain all of the information that may be important
to you. You should carefully read this prospectus, and all other information
that is incorporated by reference into this prospectus, in its entirety before
you decide to invest in our common stock.

                          Gold Banc Corporation, Inc.

Overview

   We provide a full-range of community banking and related financial services
at 28 locations in Kansas, Oklahoma and Missouri. As a multi-bank holding
company, we own nine commercial banks, one federal savings bank, an investment
advisory company, a trust company, a computer services business and an
insurance agency. Since December 1978, we have grown internally and through
acquisitions from a one bank holding company with $2.9 million in total assets
to a bank holding company with ten banks and four non-bank subsidiaries, with
$1.1 billion in total assets at March 31, 1999. A significant amount of our
growth occurred in 1998, during which we acquired 6 banks operating in 13
locations with $514.7 million in total assets. Our growth has been based on a
community banking strategy, which we believe our customers value because it
combines a focus on local communities with the breadth in product and service
offerings of a larger bank.

Community Banking Strategy

   Our strategy is to build responsive community banking offices with local
decision making authority. To implement this strategy, each of our subsidiary
banks maintains its own distinct local identity, complete with local decision
makers who are empowered, with certain limitations, to make credit decisions.

   We view each subsidiary bank president as the head of a financial services
center, where a primary focus is serving small to medium-sized businesses and
their owner-operators. These customers value one-stop shopping which we offer
through our bank subsidiaries. More than 80 percent of our loans in Johnson
County, Kansas and Tulsa, Oklahoma (our two largest markets) are provided to
local businesses. Each subsidiary bank maintains a local board of directors
that helps support the vital role our subsidiary banks play in identifying and
fulfilling the different needs of locally owned businesses in their respective
communities.

   One of our goals is to create a more efficient organization within the
framework of our community banking philosophy. While each of our subsidiary
banks operates separately, we are centralizing certain management and
administrative functions, including data processing, human resources and
regulatory administration, in order to take advantage of economies of scale.
Following our acquisition of CompuNet Engineering, Inc. in the first quarter of
1999, CompuNet will administer our consolidated back office operations,
including the operation of our data and call centers for all of our subsidiary
banks. We also provide direction for our subsidiary banks in areas of budget,
asset/liability and investment portfolio management and credit review. We feel
centralizing these functions, which involve little contact with our customers,
will allow us to run our business more efficiently, help lower our operating
expenses and enable our bank employees to focus on customer service and
community involvement.

Geographic Growth into Metropolitan Areas

   While we continue to operate in select county seat towns, our market
strategy increasingly focuses on larger growing suburbs and cities and on
serving the thousands of small-to-medium-sized businesses and their owner
operators located in these communities that are responsible for driving much of
this growth. Reflective

                                       3
<PAGE>

of our increasing focus on vibrant metropolitan markets, as of December 31,
1998, approximately 58 percent of our assets were deployed in four markets
which support a large base of small-to-medium sized businesses:

  . Johnson County, Kansas;

  . Tulsa, Oklahoma;

  . Pittsburg, Kansas; and

  . St. Joseph, Missouri.

   We believe that a recent wave of acquisitions of local banks in these
communities by larger, more regional competitors and the conversion of these
bank franchises to branch locations of much larger entities which has resulted
in the elimination of local decision making have caused a number of customers
of these locations to become dissatisfied. This has created an opportunity for
us to attract and retain loan customers whose businesses require flexibility
and responsiveness in lending decisions and a more personalized banking
relationship.

Growth into Non-Bank Services

   In addition to our growth in assets, deposits and geographic locations, we
have also expanded our product and service offerings. We provide more than
traditional deposit accounts and loans. Since the beginning of 1998, we have
added three non-bank businesses to further our objective of becoming a complete
financial services provider for small-to-medium sized businesses and their
owner operators and other customers. We now offer:

  . Investment management and retail brokerage services through Midwest
    Capital Management, Inc.;

  . Business and personal insurance through Gold Banc Financial Services,
    Inc.; and

  . Trust services and employee benefit accounts, including 401(k) plans,
    through The Trust Company.

   In addition, through our acquisition of CompuNet, we now offer certain
technology services to financial institutions and other businesses. CompuNet
designs, implements, integrates and administers local and wide area computer
networks and also provides such technology services as Y2K compliance support,
Internet solutions and video conferencing.

Growth into New Technology

   We continue to employ new technologies to serve and retain customers.
Through the use of two-way videoconferencing, our bank customers have the
opportunity to visit one-on-one with our non-bank professionals while in the
familiar convenience of their own local bank. During the second quarter of 1999
we expect to premier our Internet banking system which, in addition to our
Interactive Voice Response telephone system, allows our bank customers
convenient 24-hour remote access to their account information. We believe these
services are important to certain of our banking customers, including small-
business owners, and provide an opportunity to strengthen and develop
relationships with these customers.

Growth through Acquisitions

   In addition to internal growth, we will continue to look for opportunities
to grow through acquisitions of community banks or non-bank providers of
financial services located in:


  . metropolitan areas and county seat towns in the Midwest (primarily in
    Kansas, Oklahoma and Missouri, but also in other contiguous states), and

  . other metropolitan areas outside the Midwest where we believe our
    strategy and operating philosophy can be successful.

We believe that there will continue to be owners of small community banks that
will be interested in selling their banks to an organization such as ours that
has strong capital, a broad array of products and services,

                                       4
<PAGE>

management talent, and a commitment to retaining the local identities of its
subsidiaries. Other reasons that banks may continue to be willing to sell are a
lack of liquidity in the stock of the company and an increasing cost associated
with upgrading technology and maintaining compliance with bank regulations. We
will continue to look to acquire banks with strong existing management teams so
that our strategies can be implemented within the existing management
structures, boards of directors and bank charters that are in place at these
banks. Consistent with our growth strategy, we are regularly analyzing
acquisition opportunities and negotiating potential acquisitions. Currently, we
have not entered into any definitive agreements.

Recent Developments

   On May 17, 1999, GBCI Capital Trust II, a Delaware business trust, issued
$35,000,000 of 9.12% preferred securities in a public offering lead-managed by
the underwriter. On June 3, 1999, the underwriters for this offering exercised
an option to purchase an additional $2,550,000 of 9.12% preferred securities to
cover over allotments. The trust invested the proceeds of the offering in our
9.12% junior subordinated deferrable interest debentures. We will use the net
proceeds from the issuance of our debentures to finance growth, repay
approximately $11.0 million of corporate indebtedness and for general corporate
purposes.

   Our principal executive office is located at 11301 Nall Avenue, Leawood,
Kansas 66211, and our telephone number is (913) 451-8050.

information has been restated to include acquisitions accounted for as poolings
of interests and per share information has been restated to reflect a two-for-
one stock split of our common stock in 1998. You should read this selected
consolidated financial information in conjunction with our consolidated
financial statements and notes that appear in our Annual Report on Form 10-K
for 1998 and our Quarterly Report on Form 10-Q for the quarter ended March 31,
1999 that are incorporated by reference into this prospectus. See
"Incorporation of Certain Documents by Reference." Financial data for the three
months ended March 31, 1999 and 1998, are unaudited. In the opinion of our
management, all adjustments (consisting only of normal recurring accruals)
necessary for a fair presentation have been included. The data for the three
months ended March 31, 1999, are not necessarily indicative of what our results
of operations will be for the year ending December 31, 1999, or for any other
period.

   respectively. Additionally, the return on average assets and return on
   average equity ratios are shown on a proforma basis to reflect an
   adjustment for income taxes on Citizens' earnings for 1998 and 1997.
   Returns on average assets for 1998 and 1997 on an actual basis were 1.22%
   and 1.35%, respectively. Returns on an average equity for 1998 and 1997 on
   an actual basis were 15.14% and 15.56%, respectively. For the quarter ended
   March 31, 1998, adjusting for income taxes on Citizens' earnings, actual
   earnings and earnings per share were $2,811 and $0.17, respectively. Return
   on average assets and return on average equity for the first quarter of
   1998, adjusting for income taxes on Citizens' earnings, were 1.29% and
   15.25%, respectively.
(2) Prior to the second quarter of 1997, we had not paid cash dividends on
    shares of our common stock. The dividends paid and dividend payout ratio
    do not reflect a restatement of dividends paid prior to 1998 by entities
    we acquired in pooling of interests transactions in 1998.

                                  RISK FACTORS

   You should carefully consider the following risk factors before purchasing
the common stock offered by this prospectus. This prospectus contains forward-
looking statements that involve risk and uncertainties. You can identify these
forward-looking statements because they may include terms such as "believes,"
"anticipates," "intends," "expects," or similar expressions, and may include
discussions of future strategy. We caution you not to rely unduly on any
forward-looking statements in this prospectus. Our actual results could differ
materially from the forward-looking statements. The risk factors described
below could cause or contribute to these differences and apply to all forward-
looking statements wherever they appear in this prospectus. However, there
could be other factors not listed below that may affect us. We may not update
these risk factors or publicly announce revisions to forward-looking statements
contained in this prospectus.

We depend primarily on any dividends we may receive from our subsidiaries to
pay dividends on our common stock, if any.

   We are a separate legal entity from our subsidiaries and do not have
significant operations of our own. We depend primarily on any dividends we
receive from our subsidiaries, which may be limited by statute and regulations,
and our cash and liquid investments, to pay dividends on our common stock, if
any. Even if our subsidiaries are able to generate sufficient earnings to pay
dividends to us, there is no assurance that their respective Boards of
Directors might not decide to retain a greater portion of their earnings to
maintain existing capital or achieve additional capital necessary in light of
the financial condition, asset quality or regulatory requirements of the
subsidiaries and other business considerations.

   We currently have two subsidiaries that have an aggregate liquidation amount
of $63.75 million of trust preferred securities outstanding. The subsidiaries
invested the proceeds from the sale of the trust preferred securities in a like
amount of our junior subordinated deferrable interest debentures. We have the
right to defer interest payments on the debentures. If we defer interest
payments on the debentures, we will be prohibited, subject to certain
exceptions, from declaring or paying cash dividends on our common stock or our
debt securities that rank equally with the debentures, until we pay all
deferred amounts on the debentures.

It may be difficult for us to maintain our rapid growth.

   We have completed several acquisitions in the past few years that have
significantly enhanced our rate of growth. We cannot be certain that we will
continue to sustain this rate of growth or grow at all. Competition for
suitable acquisition candidates is intense. We are targeting acquisition
candidates, particularly in the metropolitan and suburban areas, that a variety
of larger financial institutions are also interested in acquiring. We have
reviewed potential acquisition candidates and held preliminary discussions with
several of these candidates. We cannot assure you that any of these discussions
will be successful. As a result, we may not be successful in identifying
acquisition candidates or be able to acquire banks and businesses on terms we
feel are favorable.

   The rural market areas we now serve afford limited, if any, opportunities
for growth. We believe future growth in our earnings will depend, in addition
to acquisitions, on our growth in the metropolitan and suburban market areas
where we have branches. The financial institutions in these metropolitan and
suburban areas also compete intensely for assets and deposits. This competition
may adversely affect our ability to grow our asset and deposit base profitably.

We may experience difficulties in managing our growth.

   As part of our general strategy, we may continue to acquire banks and
businesses that we believe provide a strategic fit with our business. To the
extent that we do grow, we cannot assure you that we will be able to

                                       8
<PAGE>

adequately and profitably manage such growth. Acquiring other banks and
businesses will involve risks commonly associated with acquisitions, including:

  . potential exposure to liabilities of banks and businesses we acquire;

  . difficulty and expense of integrating the operations and personnel of
    banks and businesses we acquire;

  . potential disruption to our business;

  . potential diversion of our management's time and attention;

  . impairment of relationships with and the possible loss of key employees
    and customers of the banks and businesses we acquire; and

  . incurrence of amortization expense if we account for an acquisition as a
    purchase and dilution to our stockholders if we use our common stock as
    consideration for the acquisition.

The loss of certain key personnel could adversely affect our operations.

   Our success depends in large part on the retention of a limited number of
key persons, including:

  . Michael W. Gullion, our Chairman and Chief Executive Officer;

  . Malcolm M. Aslin, our President and Chief Operating Officer;

  . Keith E. Bouchey, our Executive Vice President, Chief Financial Officer
    and Corporate Secretary; and

  . Joseph F. Smith, our Executive Vice President and Chief Technology
    Officer.

   We will likely undergo a difficult transition period if we lose the services
of any or all of these individuals. In recognition of this risk, we own and are
the beneficiary of an insurance policy on the life of Mr. Gullion providing
death benefits of $1.5 million and have entered into employment agreements with
Messrs. Gullion, Aslin, Bouchey and Smith.

   We also place great value on the experience of the presidents of our
subsidiaries and the branches of our subsidiaries and on their relationships
with the communities they serve. The loss of these key persons could negatively
impact the affected banking locations. There is no assurance we will be able to
retain our current key personnel or attract additional qualified key persons as
needed.

Changes in the local economic conditions could adversely affect our loan
portfolio.

   Our success depends to a certain extent upon the general economic conditions
of the local markets that we serve. Unlike larger banks that are more
geographically diversified, we provide banking and financial services to
customers in those markets in Kansas, Oklahoma and Missouri, including a number
of rural markets, where our subsidiary banks operate. Our commercial, real
estate and construction loans, and the ability of the borrowers to repay these
loans and the value of the collateral securing these loans, are impacted by the
local economic conditions. In the rural markets we serve, the predominant
economic sector is agriculture. Changes in the agricultural economy may have an
impact on our results of operations and financial condition. We cannot assure
you that favorable economic conditions will exist in such markets.

Our allowance for loan losses may not be adequate to cover actual loan losses.

   As a lender, we are exposed to the risk that our customers will be unable to
repay their loans according to their terms and that any collateral securing the
payment of their loans may not be sufficient to assure repayment. Credit losses
are inherent in the lending business and could have a material adverse effect
on our operating results. Our credit risk with respect to our real estate and
construction loan portfolio relates principally to the general creditworthiness
of individuals and the value of real estate serving as security for the
repayment of loans. Our credit risk with respect to our commercial and consumer
installment loan portfolio relates principally to the general creditworthiness
of businesses and individuals within our local markets.

                                       9
<PAGE>

   We make various assumptions and judgments about the collectability of our
loan portfolio and provide an allowance for potential losses based on a number
of factors. If our assumptions are wrong, our allowance for loan losses may not
be sufficient to cover our loan losses. We may have to increase the allowance
in the future. Material additions to our allowance for loan losses would
decrease our net income.

We may be unable to manage interest rate risks that could reduce our net
interest income.

   Like other financial institutions, our results of operations are impacted
principally by net interest income which is the difference between interest
earned on loans and investments and interest expense paid on deposits and other
borrowings. We cannot predict or control changes in interest rates. Regional
and local economic conditions and the policies of regulatory authorities,
including monetary policies of the Federal Reserve, affect interest income and
interest expense. While we continually take measures intended to manage the
risks from changes in market interest rates, changes in interest rates can
still have a material adverse effect on our profitability.

We cannot predict how changes in technology will impact our business.

   The financial services market, including banking services, is increasingly
affected by advances in technology, including developments in:

  . telecommunications;

  . data processing;

  . automation;

  . Internet-based banking;

  . telebanking; and

  . debit cards and so-called "smart cards."

   Our ability to compete successfully in the future will depend on whether we
can anticipate and respond to technological changes. To develop these and other
new technologies we will likely have to make additional capital investments.
Although we continually invest in new technology, we cannot assure you that we
will have sufficient resources or access to the necessary proprietary
technology to remain competitive in the future.

The banking business is highly competitive.

   We operate in a competitive environment. In the metropolitan and suburban
areas in which we compete, other commercial banks, savings and loan
associations, credit unions, finance companies, mutual funds, insurance
companies, and brokerage and investment banking firms and other financial
intermediaries offer similar services. We also face competition in our rural
markets. Many of these competitors have substantially greater resources and
lending limits and may offer certain services our subsidiary banks and
businesses do not currently provide. In addition, some of the nonbank
competitors are not subject to the same extensive regulations that govern our
subsidiary banks and businesses. Our profitability depends upon the ability of
our subsidiaries to compete in our primary market areas.

Our operations may be adversely affected if we, or certain persons with whom we
do business, fail to adequately address the Year 2000 issue.

   Certain of our older computer programs identify years with two digits
instead of four. If not remedied, this is likely to cause problems because
these programs may recognize the year 2000 as the year 1900. As with other
financial institutions, we engage in a significant amount of business and
reporting activity that depends on accurate date information, such as
calculation of interest and other calculations pertaining to loans, deposits,
assets and investments. As a result, Year 2000 problems could result in a
system failure or miscalculations that disrupt our operations. We continue to
address these issues as they relate to our subsidiaries and corporate systems
and are in the implementation phase of our preparations for the year change
from 1999 to 2000.

                                       10
<PAGE>

   The process of remediating, the costs of remediating or failing to remediate
Year 2000 issues may be more burdensome than we anticipate. In addition, it is
possible that Year 2000 issues could have a material adverse affect on:

  . our service providers and their ability to provide us services, including
    Bankline MidAmerica, Inc. which provides a data processing system that
    most of our subsidiary banks have converted to or are scheduled to
    convert to before December 31, 1999, and

  . our customers, their businesses, and their ability to repay loans.

   The cumulative effect of such problems, if they occur, could adversely
effect our operations. For a more detailed discussion of our Year 2000
initiatives see the disclosures under "Year 2000 Initiatives" in our annual
report on Form 10-K for the year ended December 31, 1998 and under "Year 2000"
in our quarterly report on Form 10-Q for the quarter ended March 31, 1999,
which have been incorporated by reference into this prospectus.

We are subject to extensive regulation.

   The banking industry is heavily regulated under both federal and state law.
These regulations are primarily intended to protect depositors and the Federal
Deposit Insurance Corporation, not our creditors or stockholders. Our nonbank
subsidiaries are also subject to the supervision of the Federal Reserve Board,
in addition to other regulatory and self-regulatory agencies including the
Securities and Exchange Commission, the National Association of Securities
Dealers, and state securities and insurance regulators. Regulations affecting
banks and financial services businesses are undergoing continuous change, and
the ultimate effect of such changes cannot be predicted. Regulations and laws
may be modified at any time, and new legislation may be enacted that affects
us, our subsidiary banks or our nonbank subsidiaries. We cannot assure you that
such modifications or new laws will not adversely affect us.

Certain provisions of our articles of incorporation and bylaws and Kansas law
may discourage takeover attempts that you may deem to be in your best
interests.

   Certain provisions of our articles of incorporation and bylaws, certain
powers of our Board of Directors and certain sections of the corporate law of
Kansas may discourage takeover attempts not first approved by our Board of
Directors, including takeovers that certain stockholders may deem to be in
their best interests. These provisions and powers of our Board of Directors
could:

  . delay or prevent the removal of incumbent directors or the assumption of
    control by stockholders, even if such removal or assumption of control
    would be beneficial to stockholders; and

  . discourage or make more difficult a merger, tender offer or proxy
    contest, even if such events would be beneficial in the short term, to
    the interests of stockholders.

   In addition, our Board of Directors has authority to issue up to 50,000,000
shares of preferred stock in one or more series and to fix preferences, rights
and limitations of any such series without stockholder approval. This ability
to issue preferred stock could have the effect of discouraging unsolicited
acquisition proposals or making it more difficult for a third party to gain
control of us, or otherwise could adversely affect the market price of our
common stock.

Our subsidiary banks may be forced to pay for any losses the Federal Deposit
Insurance Corporation incurs if it provides assistance to any of our other
subsidiary banks.

   Federal law contains a "cross guarantee" provision that could require any of
our insured subsidiary banks to pay for losses incurred by the Federal Deposit
Insurance Corporation if it provides assistance to another of our insured
subsidiary banks or in the event a subsidiary bank fails. If another of our
subsidiary banks is assessed for any assistance the Federal Deposit Insurance
Corporation may provide, such assessment could materially effect that
subsidiary bank's financial condition as well as ours.

                              SELLING STOCKHOLDERS

Background

   The shares of common stock being offered by this prospectus were acquired by
some of the former stockholders of Citizens Bancorporation, Inc. pursuant to
the merger of Citizens into one of our wholly-owned subsidiaries. The sale of
the common stock by the selling stockholders is restricted by Rule 145
promulgated under the Securities Act, and these shares cannot be transferred
unless (a) the sale is registered under the Securities Act or (b) the transfer
is made in accordance with Rule 145 or another exemption from registration
under the Securities Act.

Registration Rights Agreement

   As part of the merger of Citizens into our wholly-owned subsidiary, we
entered into a registration rights agreement with the former stockholders of
Citizens. The material provisions of the registration rights agreement are
described below. A copy of the registration rights agreement has been
incorporated by reference as an exhibit to the registration statement.

   To facilitate resales of the shares held by the former stockholders of
Citizens, we agreed to file the Securities Act registration statement of which
this prospectus is a part. We have agreed to use reasonable efforts to keep the
registration statement continuously effective for a period ending with the
earlier of (a) the sale of all of the shares held by the former Citizens
stockholders, or (b) December 10, 1999.

   We will pay all expenses in the performance of our registration obligations
under the registration rights agreement, including all registration, filing and
qualification fees, printing expenses, and fees and disbursements of our
attorneys. The selling stockholders are responsible for:

  . any fees and expenses in excess of $1,500 (per amendment or supplement)
    in order to amend or supplement the registration statement or this
    prospectus to reflect donees or pledgees,

  . any underwriting fees, discounts or commissions relating to the sale of
    the shares,

  . expenses for any road shows or similar sales efforts, and

  . any fees or disbursements for the selling stockholders' attorneys.

   The registration rights agreement contains customary indemnification
provisions by which we are obligated to indemnify and hold harmless the selling
stockholders, and the selling stockholders are obligated under certain
circumstances to indemnify and hold us and certain related parties harmless, in
each case in connection with liabilities relating to the registration of the
shares.

   The following table sets forth the names of the selling stockholders, the
shares of common stock being offered by the selling stockholders by this
prospectus, and the number of shares of common stock the selling stockholders
will beneficially own after the consummation of this offering. All information
with respect to the beneficial ownership has been furnished by the selling
stockholders.

                                  UNDERWRITING

   Under the terms and conditions set forth in the underwriting agreement among
us, the selling stockholders, and Advest, Inc., Advest has agreed to purchase
from the selling stockholders and the selling stockholders have agreed to sell
to Advest, the number of shares of common stock set forth below:

</TABLE>

   The underwriting agreement provides that the obligations of Advest are
subject to approval of certain matters by its counsel and to various other
conditions. Advest is committed to purchase and pay for all such shares of
common stock being sold pursuant to the underwriting agreement, if any shares
of common stock are purchased.

   Advest has advised us and the selling stockholders that they propose to
offer the shares of common stock directly to the public initially at the
offering price set forth on the cover page of this prospectus and to certain
selected dealers at such price less a concession not to exceed $        per
share. Advest may allow, and such selected dealers may reallow, a concession
not in excess of $        per share to certain other dealers. After the public
offering of the shares, the public offering price, concession and reallowance
to dealers may be changed by Advest. The common stock is offered and subject to
receipt and acceptance by Advest, and to certain other conditions, including
the right to reject orders in whole or in part.

   The selling stockholders have granted to the underwriter an option,
exercisable not later than 30 days after the date of the underwriting
agreement, to purchase up to an additional 112,655 shares of common stock at
the public offering price less discounts. To the extent that the underwriter
exercises this option, the selling stockholders will be obligated, pursuant to
the option, to sell these shares of common stock to the underwriter. The
underwriter may exercise this option only to cover over-allotments made in
connection with the sale of the shares of common stock offered by this
prospectus. If purchased, the underwriter will offer these additional shares of
common stock on the same terms as those on which the 112,655 shares of common
stock are being offered.

   Subject to certain limitations, we along with the selling stockholders and
Advest have agreed to indemnify each other against certain liabilities
including liabilities under the Securities Act, or to contribute to payments
that we, the selling stockholders, or Advest may be required to make in respect
of these liabilities.

   The foregoing is a summary of the principal terms of the underwriting
agreement and does not purport to be complete. Reference is made to a copy of
the underwriting agreement that was filed as an exhibit to the registration
statement of which this prospectus is a part.

   Advest has been engaged in the ordinary course of business, and may in the
future be engaged, to perform investment banking and other advisory-related
services for us, our affiliates, and certain stockholders of ours. Advest, Inc.
also served as managing underwriter in our public offering of common stock in
1996 and trust preferred securities in 1997, and advised us in certain of our
acquisition transactions. Advest, Inc. also served as managing underwriter for
our trust preferred securities offering completed on May 17, 1999.

   In connection with the offering of the common stock, Advest and any selling
group members and their respective affiliates may engage in transactions
effected in accordance with Rule 104 of the Securities and Exchange
Commission's Regulation M that are intended to stabilize, maintain, or
otherwise affect the market price of the common stock. Such transactions may
include stabilizing transactions in which they bid for, and purchase, shares of
the common stock at a level above that which might otherwise prevail in the
open market for the purpose of preventing or retarding a decline in the market
price of the common stock. Advest also may

                                       15
<PAGE>

bid for, and purchase, shares of common stock to reduce a short position
incurred to reclaim any selling concessions otherwise accruing or allowed to a
selling group member in connection with the offering if the common stock
originally sold by such selling group member is repurchased by Advest and
therefore has not been effectively placed by such selling group member. Any of
the foregoing transactions may result in the maintenance of a price for the
common stock at a level above that which might otherwise prevail in the open
market. Neither we nor Advest makes any representation or prediction as to the
direction or magnitude of any effect that the transactions described above may
have on the price of our common stock. Advest is not required to engage in any
of the foregoing transactions and, if commenced, such transactions may be
discontinued at any time without notice.

                                 LEGAL MATTERS

   The validity of the shares of common stock offered by this prospectus has
been passed upon for us by Blackwell Sanders Peper Martin LLP, Kansas City,
Missouri. Certain legal matters in connection with the shares will be passed
upon for Advest by Arnold & Porter, Washington, D.C. Certain legal matters will
be passed upon for the selling stockholders by Crowe & Dunlevy, a Professional
Corporation, Oklahoma City, Oklahoma. Arnold & Porter will rely as to certain
matters of Kansas law on the opinion of Blackwell Sanders Peper Martin LLP.

management talent, and a commitment to retaining the local identities of its
subsidiaries. Other reasons that banks may continue to be willing to sell are a
lack of liquidity in the stock of the company and an increasing cost associated
with upgrading technology and maintaining compliance with bank regulations. We
will continue to look to acquire banks with strong existing management teams so
that our strategies can be implemented within the existing management
structures, boards of directors and bank charters that are in place at these
banks.

Recent Developments

   On May 17, 1999, GBCI Capital Trust II, a Delaware business trust, issued
$35,000,000 of 9.12% preferred securities in a public offering lead-managed by
the underwriter. The underwriters in this offering have an option to purchase
an additional $5,250,000 of 9.12% preferred securities to cover over
allotments. The trust invested the proceeds of the offering in our 9.12% junior
subordinated deferrable interest debentures. We will use the net proceeds from
the issuance of our debentures to finance growth, repay approximately $11.0
million of corporate indebtedness and for general corporate purposes.

   Our principal executive office is located at 11301 Nall Avenue, Leawood,
Kansas 66211, and our telephone number is (913) 451-8050.

                              SELLING STOCKHOLDERS

Background

   The shares of common stock being offered by this prospectus were acquired by
some of the former stockholders of Citizens Bancorporation, Inc. pursuant to
the merger of Citizens into one of our wholly-owned subsidiaries. The sale of
the common stock by the selling stockholders is restricted by Rule 145
promulgated under the Securities Act, and these shares cannot be transferred
unless (a) the sale is registered under the Securities Act or (b) the transfer
is made in accordance with Rule 145 or another exemption from registration
under the Securities Act.

Registration Rights Agreement

   As part of the merger of Citizens into our wholly-owned subsidiary, we
entered into a registration rights agreement with the former stockholders of
Citizens. The material provisions of the registration rights agreement are
described below. A copy of the registration rights agreement has been
incorporated by reference as an exhibit to the registration statement.

   To facilitate resales of the shares by the former stockholders of Citizens,
we agreed to file the Securities Act registration statement of which this
prospectus is a part. We have agreed to use reasonable efforts to keep the
registration statement continuously effective for a period ending with the
earlier of (a) the sale of all of the shares held by the former Citizens
stockholders, or (b) December 10, 1999.

   We will pay all expenses in the performance of our registration obligations
under the registration rights agreement, including all registration, filing and
qualification fees, printing expenses, and fees and disbursements of our
attorneys. The selling stockholders are responsible for:

  . any fees and expenses in excess of $1,500 (per amendment or supplement)
    in order to amend or supplement the registration statement or this
    prospectus to reflect donees or pledgees,

  . any underwriting fees, discounts or commissions relating to the sale of
    the shares,

  . expenses for any road shows or similar sales efforts, and

  . any fees or disbursements for the selling stockholders' attorneys.

   The registration rights agreement contains customary indemnification
provisions by which we are obligated to indemnify and hold harmless the selling
stockholders, and the selling stockholders are obligated under certain
circumstances to indemnify and hold us and certain related parties harmless, in
each case in connection with liabilities relating to the registration of the
shares.

   The following table sets forth the names of the selling stockholders, the
shares of common stock being offered by the selling stockholders by this
prospectus, and the number of shares of common stock the selling stockholders
will beneficially own after the consummation of this offering. All information
with respect to the beneficial ownership has been furnished by the selling
stockholders.

                [ALTERNATE PAGE FOR NON-UNDERWRITTEN PROSPECTUS]

                              PLAN OF DISTRIBUTION

   The selling stockholders or their respective pledgees, donees, transferees
or other successors in interest may, from time to time, sell all or a portion
of the shares on the Nasdaq National Market, in privately negotiated
transactions or otherwise. Shares may be sold at fixed prices that may be
changed, at market prices prevailing at the time of sale, at prices related to
such market prices or negotiated prices. The shares may be sold by the selling
stockholders by one or more of the following methods, without limitation:

  . block trades in which the broker or dealer so engaged will attempt to
    sell the shares as agent but may position and resell a portion of the
    block as principal to facilitate the transaction;

  . purchases by a broker or dealer as principal and resale by such broker or
    dealer for its account pursuant to this prospectus;

  . ordinary brokerage transactions and transactions in which the broker
    solicits purchasers;

  . privately negotiated transactions;

  . short sales;

  . through the writing of options on the shares; and

  . a combination of any such methods of sale.

   In effecting sales, brokers and dealers engaged by the selling stockholders
may arrange for other brokers or dealers to participate. Broker-dealers may
agree with the selling stockholders to sell a specified number of such shares
at a stipulated price per share. To the extent such broker-dealer is unable to
do so acting as agent for a selling stockholder, it may agree to purchase as
principal any unsold shares at the stipulated price. Broker-dealers who acquire
shares as principals may thereafter resell such shares from time to time in
transactions in the Nasdaq National Market at prices and on terms then
prevailing at the time of sale, at prices related to the then-current market
price or in negotiated transactions. Broker-dealers may use block transactions
and sales to and through broker-dealers, including transactions of the nature
described above. The selling stockholders may also sell the shares in
accordance with Rule 145 under the Securities Act rather than pursuant to this
prospectus.

   From time to time, one or more of the selling stockholders may pledge,
hypothecate or grant a security interest in some of all of the shares owned by
them. The pledgees, secured parties or persons to whom such securities have
been hypothecated will, upon foreclosure in the event of default, be deemed to
be selling stockholders. The number of a selling stockholder's shares offered
under this prospectus will decrease as and when it takes such actions. The plan
of distribution for such selling stockholder's shares will otherwise remain
unchanged. In addition, a selling stockholder may, from time to time, sell
short our common stock and in such instances, this prospectus may be delivered
in connection with such short sales and the shares offered under this
prospectus may be used to cover such short sales.

   To the extent required under the Securities Act the aggregate amount of
selling stockholders' shares of our common stock being offered and the terms of
the offering, the names of any such agents, brokers, dealers or underwriters
and any applicable commission with respect to a particular offer will be set
forth in an accompanying prospectus supplement. Any underwriters, dealers,
brokers or agents participating in the distribution of our common stock may
receive compensation in the form of underwriting discounts, concessions,
commissions or fees from a selling stockholder and/or purchasers of selling
stockholders' shares of common stock, for whom they may act (which compensation
as to a particular broker-dealer might be in excess of customary commissions).

   The selling stockholders and any broker-dealers or agents that participate
with the selling stockholders in sales of the shares may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with such
sales. In such event, any commissions received by such broker-dealers or agents
and any profit on the resale of the shares purchased by them may be deemed to
be an underwriting commission or discount under the Securities Act.

<PAGE>

                [ALTERNATE PAGE FOR NON-UNDERWRITTEN PROSPECTUS]

   A selling stockholder may enter into hedging transactions with broker-
dealers and the broker-dealers may engage in short sales of the common stock in
the course of hedging the positions they assume with such selling stockholder,
including in connection with distributions of the common stock by such broker-
dealers. A selling stockholder may enter into option or other transactions with
broker-dealers that involve the delivery of the shares offered hereby to the
broker-dealers, who may then resell or otherwise transfer such shares. A
selling stockholder may also loan or pledge the shares offered hereby to a
broker-dealer and the broker-dealer may sell the shares offered hereby so
loaned or upon a default may sell or otherwise transfer the pledged shares
offered hereby.

   The selling stockholders and any other persons participating in the sale or
distribution of the shares will be subject to applicable provisions of the
Securities Exchange Act and the rules and regulations thereunder, which
provisions may limit the timing of purchases and sales of any of the shares by
the selling stockholders or any other such person. The foregoing may affect the
marketability of the shares.

   In order to comply with the securities laws of certain states, if
applicable, the shares offered by this prospectus may be sold in such
jurisdictions only through registered or licensed brokers or dealers. In
addition, in certain states the shares may not be sold unless they have been
registered or qualified for sale or an exemption from registration or
qualification requirements is available and is complied with.

   We will make copies of this prospectus available to the selling stockholders
and have informed the selling stockholders that they must deliver a copy of
this prospectus to each purchaser of the shares prior to or at the time of any
sale. We have agreed with the selling stockholders to keep this prospectus
effective until the earlier of (i) the sale of all of the shares or (ii)
December 10, 1999.

                                 LEGAL MATTERS

   The legality of the shares offered pursuant to the offering will be passed
upon for us by Blackwell Sanders Peper Martin LLP, Kansas City, Missouri.

Item 15. Indemnification of Directors and Officers.

   Gold Banc Corporation, Inc.'s (the "Company") Restated Articles of
Incorporation, as amended, and Amended and Restated Bylaws require it to
indemnify its directors and officers and advisory directors against
liabilities, fines, penalties, settlements, claims and reasonable expenses
incurred by them in connection with any proceeding to which they may be made a
party by reason of their service in those capacities to the fullest extent
permitted by the Kansas General Corporation Code ("KGCC"). The KGCC permits a
corporation to indemnify its present and former directors and officers if
ordered to do so by a court or after a determination by its independent
counsel, stockholders or a majority of its disinterested directors that the
person to be indemnified acted in good faith and in a manner such person
reasonably believed to be in or not opposed to the best interests of the
corporation.

   Pursuant to express authority conferred in the Company's Amended and
Restated Bylaws, the Company maintains a policy of insurance, under which the
insurer will, subject to certain conditions, defend the directors and officers
of the Company against and indemnify them from any liabilities in capacities as
such.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or controlling persons pursuant to the
foregoing provisions, the Company has been informed that in the opinion of the
SEC such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

Item 17. Undertakings.

   (a) 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
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
proceedings) 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.

   (b) The undersigned Registrant hereby undertakes to, for purposes of
determining any liability under the Securities Act, treat the information
omitted from the form of prospectus filed as part of this registration
statement in reliance upon Rule 430A and contained in a form of prospectus
filed by the Registrant under Rule 424(b)(1), or (4) or 497(h) under the
Securities Act as part of this registration statement as of the time the SEC
declared it effective.

   (c) The undersigned Registrant hereby undertakes to, for purposes of
determining any liability under the Securities Act, treat each post-effective
amendment that contains a form of prospectus as a new registration statement
for the securities offered in the registration statement, and that offering of
the securities at that time as the initial bona fide offering of those
securities.

   (d) 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
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

                                      II-2
<PAGE>

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.

   (e) The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made
  of securities registered hereby, 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; and

       (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;

  Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
