                                 PROXY STATEMENT

This proxy statement is furnished in connection with the solicitation by the
board of directors of UnionBancorp, Inc. of proxies to be voted at the annual
meeting of stockholders to be held at the Starved Rock Lodge and Conference
Center located in Utica, Illinois, on Tuesday, April 27, 2004, at 10:00 a.m.,
local time, or at any adjournments or postponements of the meeting.

UnionBancorp, a Delaware corporation, is a regional financial services company
based in Ottawa, Illinois which has three bank subsidiaries and one non-bank
subsidiary. Our banks serve communities throughout Central, Northern and Western
Illinois through twenty-five locations. UnionFinancial Services & Trust Company,
our non-bank subsidiary, is an insurance/brokerage agency and trust company.

The proxy statement and the accompanying notice of meeting and proxy are first
being mailed to holders of shares of our common stock, par value $1.00 per
share, on or about March 24, 2004. Our 2003 annual report, including financial
statements, is enclosed.

Voting Rights and Proxy Information

The board of directors has fixed the close of business on March 1, 2004, as the
record date for the determination of stockholders entitled to notice of, and to
vote at, the annual meeting. Our transfer books will not be closed between the
record date and the date of the annual meeting. The board of directors hopes
that all stockholders can be represented at the annual meeting. Whether or not
you expect to be present, please sign and return your proxy in the enclosed
self-addressed, stamped envelope. Stockholders giving proxies retain the right
to revoke them at any time before they are voted by written notice of revocation
to the Secretary of UnionBancorp, and stockholders present at the meeting may
revoke their proxy and vote in person.

On March 1, 2004, we had 4,034,500 issued and outstanding shares of common
stock. For the election of directors, and for all other matters to be voted upon
at the annual meeting, each share of common stock is entitled to one vote. A
majority of the outstanding shares of the common stock must be present in person
or represented by proxy to constitute a quorum for purposes of the annual
meeting. Abstentions and broker non-votes will be counted for purposes of
determining a quorum. Directors will be elected by a plurality of the votes
present in person or represented by proxy at the meeting and entitled to vote.
In all other matters, the affirmative vote of the majority of shares of common
stock present in person or represented by proxy at the annual meeting and
entitled to vote on the subject matter shall be required to constitute
stockholder approval. Abstentions will be treated as votes against a proposal
and broker non-votes will have no effect on the vote.

                                       1.


                         I.       ELECTION OF DIRECTORS

We have a staggered board of directors, divided into three classes. One class is
elected annually to serve for three years. At the annual meeting, our
stockholders will be entitled to elect three Class III directors for terms of
three years or until their successors are elected and qualified. Each of the
nominees for election as Class III directors are incumbent directors. Our board
of directors has determined that each of Messrs. Breipohl, Doty, McDonnell,
Reinhardt, Shinkle, Sullivan and Trainor are independent as independence is
defined in the National Association of Securities Dealers' listing standards, as
those standards have been modified or supplemented.

The proxy provides instructions for voting for all director nominees or for
withholding authority to vote for one or more director nominees. Unless
instructed to the contrary, the persons acting under the proxy which we are
soliciting will vote for the nominees listed below. In the event, however, that
any nominee shall be unable to serve, which is not now contemplated, the proxy
holders reserve the right to vote at the annual meeting for a substitute
nominee.

Information About Directors and Nominees

Set forth below is information, current as of March 1, 2004, concerning the
nominees for election and for the other directors whose terms of office will
continue after the meeting, including the age, year first elected a director and
business experience of each during the previous five years. Unless otherwise
indicated, each person has held the positions shown for at least five years. The
three nominees, if elected at the annual meeting, will serve as Class III
directors for three-year terms, expiring in 2007. We recommend that you vote
your shares FOR all three nominees.

All of our directors will hold office for the terms indicated, or until their
respective successors are duly elected and qualified. There are no arrangements
or understandings between UnionBancorp and any person pursuant to which any
director has been selected. No member of the board of directors is related to
any other member of the board of directors.

Board Committees and Meetings

Our board of directors generally meets on a quarterly basis. The board of
directors met seven times during 2003. During 2003, all directors attended at
least 75 percent of the meetings of the board and the committees on which they
served. Our board of directors has standing executive, audit and compensation
committees.

The executive committee is comprised of Messrs. McDonnell (Chair), Sullivan,
Trainor and Yaeger. The executive committee meets on an as needed basis and
exercises the power of the board of directors between board meetings. This
committee met two times in 2003.

                                       3.


The audit committee recommends independent auditors to the board, reviews the
results of the auditors' services, reviews with management and the internal
auditor the systems of internal control and internal audit reports and seeks to
assure that our books and records are kept in accordance with applicable
accounting principles and standards. The audit committee charter, which sets
forth the duties and responsibilities of the committee, is attached as an
appendix to this proxy statement. The members of the audit committee are Messrs.
Reinhardt (Chair), Breipohl and Doty. During 2003, the audit committee met three
times.

The compensation committee establishes compensation and benefits for the chief
executive officer and reviews and recommends compensation and benefits for the
other executive officers and employees of UnionBancorp and our subsidiaries. The
committee also administers and oversees our stock-based incentive compensation
plans. The members of the compensation committee are Messrs. Shinkle (Chair),
McDonnell, Sullivan and Dewey R. Yaeger (ex officio). The compensation committee
met four times in 2003.

Nominating Committee

Our board of directors has a nominating committee which consists of three
directors. Messrs. McDonnell (Chair), Shinkle and Sullivan are the current
members of this committee. The nominating committee identifies individuals to
become board members and selects, or recommends for the board's selection,
director nominees to be presented for shareholder approval at the annual meeting
of shareholders or to fill any vacancies. During 2003, the nominating committee,
as currently comprised, held no meetings because it was not formed until March
18, 2004. Prior to the formation of the formal nominating committee, the
executive committee or entire board served the functions of the nominating
committee. The board met on December 18, 2003, and nominated the current
nominees for re-election at this year's annual meeting.

Our board of directors has adopted a written charter for the nominating
committee, a copy of which is attached as an appendix to this proxy statement.
Each of the members of our nominating committee is independent as independence
is defined in the National Association of Securities Dealers' listing standards,
as those standards have been modified or supplemented.

The nominating committee's policy is to consider director candidates recommended
by shareholders. Such recommendations must be made pursuant to timely notice in
writing to:

                               UnionBancorp, Inc.
                              321 West Main Street
                             Ottawa, Illinois 61350
                         Attention: Nominating Committee

The nominating committee has not established specific, minimum qualifications
for recommended nominees or specific qualities or skills for one or more of our
directors to possess. The nominating committee uses a subjective process for
identifying and evaluating nominees for director, based on the information
available to, and the subjective judgments of, the members of the nominating
committee and our then current needs, although the committee does not believe
there would be any difference in the manner in which it evaluates nominees based
on whether the nominee is recommended by a shareholder. Historically, nominees
have been existing directors or business associates of our directors or
officers.

                                       4.


Code of Ethics

The Company has adopted a Code of Ethics that applies to all of our employees,
officers and directors, including our principal executive officer, principal
financial officer, principal accounting officer or controller, or persons
performing similar functions. Our Code of Ethics contains written standards that
we believe are reasonably designed to deter wrongdoing and to promote:

         o    Honest and ethical conduct, including the ethical handling of
              actual or apparent conflicts of interest between personal and
              professional relationships;
         o    Full, fair, accurate, timely, and understandable disclosure in
              reports and documents that we file with, or submit to, the
              Securities and Exchange Commissions and in other public
              communications we make;
         o    Compliance with applicable governmental laws, rules and
              regulations;
         o    The prompt internal reporting of violations of the code to an
              appropriate person or persons named in the code; and
         o    Accountability for adherence to the code.

This Code of Ethics is attached to our Annual Report on Form 10-K for the fiscal
year ended December 31, 2003 as Exhibit 14. We will provide to any person
without charge, upon request, a copy of our Code of Ethics. Requests for a copy
of our Code of Ethics should be made to our secretary at 321 West Main Street,
Ottawa, Illinois 61350.

Shareholder Communications with the Board

Our board of directors has a process for shareholders to send communications to
the board of directors, its nominating committee or its audit committee,
including complaints regarding accounting, internal accounting controls, or
auditing matters. Communications can be sent to the board of directors, its
nominating committee or its audit committee or specific directors either by
regular mail to the attention of the board of directors, its nominating
committee, its audit committee or specific directors, at our principal executive
offices at 321 West Main Street, Ottawa, Illinois 61350. All of these
communications will be reviewed by our secretary (1) to filter out
communications that our secretary deems are not appropriate for our directors,
such as spam and communications offering to buy or sell products or services,
and (2) to sort and relay the remainder to the appropriate directors. We
encourage all of our directors to attend the annual meeting of shareholders, if
possible. All of our directors attended the 2003 annual meeting of shareholders.

Compensation of Directors

Each of our directors was paid a fee of $1,000 for each board meeting attended
and $250 for each committee meeting attended. In addition, each director was
paid an annual retainer of $2,500. Each of our directors may also receive an
annual grant of options to purchase shares of common stock under the
UnionBancorp, Inc. 2003 Stock Option Plan. The UnionBancorp, Inc. 2003 Stock
Option Plan provides for annual formula grants to each of our directors of
options to purchase shares of common stock with an exercise price of not less
than 100% of the then current market price of the common stock on the date of
the grant. Such options become exercisable over five years. During 2003, each
non-employee director was granted options to purchase 2,500 shares of common
stock at a price of $23.29 per share.

                                       5.


Existing Equity Compensation Plans

Section 16(a) Beneficial Ownership Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires that our executive
officers, directors and persons who own more than 10% of our common stock file
reports of ownership and changes in ownership with the Securities and Exchange
Commission. They are also required to furnish us with copies of all Section
16(a) forms they file. Based solely on our review of the copies of such forms,
and, if appropriate, representations made to us by any reporting person
concerning whether a Form 5 was required to be filed for 2003, we are not aware
that any of our directors, executive officers or 10% stockholders failed to
comply with the filing requirements of Section 16(a) during 2003, except each of
the directors failed to file a Form 4 in connection with options granted to them
by the Company on December 18, 2003. In addition, two directors (Shinkle and
Sullivan) each failed to file three Form 4's reporting one transaction per
report in connection with the purchase of Company common stock through a
broker-maintained dividend reinvestment plan. Mr. Shinkle also failed to file
one Form 4 in connection with a single purchase transaction in 1998.

Employment Agreements and Other Arrangements

We are not a party to any employment agreements with our executive officers,
except for the following:

An employment agreement was entered into on August 22, 2001 with Paul R.
Tingley, president and chief executive officer of UnionFinancial Services &
Trust Company. The employment agreement with Mr. Tingley provides that beginning
January 2002, UnionBancorp, Inc. will pay Mr. Tingley a minimum of $10,000
monthly. Mr. Tingley's total compensation, including bonuses, is valued at
$150,000 annually. Mr. Tingley is entitled to other customary employee benefits
provided by UnionBancorp. Mr. Tingley's employment agreement was to terminate on
August 22, 2004. Effective February 27, 2004, Mr. Tingley resigned from
UnionFinancial Services & Trust Company. Mr. Tingley entered into an amended
agreement with UnionBancorp, whereby Mr. Tingley would continue to receive
$10,000 monthly through the termination of his contract but would not be
eligible for bonuses during this period. Mr. Tingley will continue to receive
customary employee benefits through the expiration of the agreement on August
22, 2004.

                                       10.


Effective September 3, 2003, Mr. Grako resigned as president and chief executive
officer of UnionBancorp. In recognition of his service, the board approved a
severance package for Mr. Grako which included monthly payments of $5,000 for a
period of 18 consecutive months commencing October 31, 2003 and ending March 31,
2005. In addition, the Company shall continue in effect the bank owned life
insurance policy (BOLI) on Mr. Grako which provides a death benefit of $600,000
to Mr. Grako's beneficiary. This policy had a present value of approximately
$86,000.

On November 3, 2003, the Company entered into change of control agreements with
three of its executives, Rick R. Clary, Everett J. Solon and Kurt R. Stevenson.
The agreements provide that if, within two years after a change in control
occurs, the executive's employment is terminated without "good cause," then the
executive shall receive a cash payment equal to two times the executive's
salary.

Compensation Committee Interlocks and Insider Participation

During 2003, the members of the compensation committee were Messrs. Shinkle
(Chair), McDonnell, Sullivan and Yaeger (ex officio). None of these individuals
was an officer or employee of UnionBancorp or any of our subsidiaries during
2003, and none of these individuals is a former officer or employee of
UnionBancorp or any of our subsidiaries, except for Mr. Yaeger who is president
and chief executive officer. Mr. Yaeger did not participate in any decisions
pertaining to his compensation.

Board Compensation Committee Report on Executive Compensation

The incorporation by reference of this proxy statement into any document filed
with the Securities and Exchange Commission by UnionBancorp shall not be deemed
to include the following report unless the report is specifically stated to be
incorporated by reference into such document.

The compensation committee of our board of directors is comprised of three
independent directors and is responsible for providing oversight to ensure that
the company's compensation incentives are competitive and that they are aligned
to allow company goals to be successfully achieved. In determining compensation,
the following factors are generally taken into consideration:

         o        the performance of the executive officers in achieving our
                  short and long-term goals;

         o        payment of compensation commensurate with the ability and
                  expertise of the executive officers; and

         o        payment of compensation that is competitive with similar
                  companies.

The committee considers the foregoing factors, as well as others, in determining
compensation. There is no assigned weight given to any of these factors.

Additionally, the compensation committee considers various benefits, such as our
employee stock ownership plan, 401(k) plan and the stock option plan, together
with perquisites in determining compensation. The committee believes that the
benefits provided through the stock-based plans more closely tie the
compensation of the officers to the interests of the stockholders and provide
significant additional performance incentives for the officers which directly
benefit the stockholders through an increase in the stock value.

                                       11.


Annually, the compensation committee evaluates four primary areas of performance
in determining the chief executive officer's level of compensation. These areas
are:

         o        long-range strategic planning and implementation;

         o        our financial performance;

         o        our compliance with regulatory requirements and relations with
                  regulatory agencies; and

         o        the individual's effectiveness of managing relationships with
                  stockholders and the board of directors.

When evaluating our financial performance, the committee considers
profitability, asset growth, asset quality and risk management. The primary
evaluation criteria are considered to be essential to our long-term viability
and are given equal weight in the evaluation. Finally, the committee reviewed
compensation packages of peer institutions, as well as compensation surveys
provided by independent third parties, to ensure that the chief executive
officer's compensation is competitive and commensurate with his level of
performance.

                             Compensation Committee:
                             John A. Shinkle (Chair)
                               Dennis J. McDonnell
                                Scott C. Sullivan
                          Dewey R. Yaeger (ex officio)


                                       12.

                          TRANSACTIONS WITH MANAGEMENT

Several of our directors and executive officers (including their affiliates,
families and companies in which they are principal owners, officers or
directors) were loan customers of, and had other transactions with, us and our
subsidiaries in the ordinary course of business. These loans and lines of credit
were made in the ordinary course of business on substantially the same terms,
including interest rates and collateral, as those prevailing at the time for
transactions with other persons and did not involve more than the normal risk of
collectibility or present other unfavorable features. During 2003, we paid
approximately $135,907 to the law firm of Myers, Berry, O'Conor & Kuzma, Ltd.
for legal services. Richard J. Berry, a director of UnionBancorp, is a principal
of that firm.

                             AUDIT COMMITTEE REPORT

The incorporation by reference of this proxy statement into any document filed
with the Securities and Exchange Commission by UnionBancorp shall not be deemed
to include the following report unless the report is specifically stated to be
incorporated by reference into such document.

The audit committee assists the board in carrying out its oversight
responsibilities for our financial reporting process, audit process and internal
controls. The audit committee also reviews the audited financial statements and
recommends to the board that they be included in our annual report on Form 10-K.
The committee is comprised solely of independent directors.

The audit committee has reviewed and discussed our audited financial statements
for the fiscal year ended December 31, 2003 with our management and Crowe,
Chizek and Company LLC, our independent auditors. The committee has also
discussed with Crowe Chizek the matters required to be discussed by SAS 61
(Codification for Statements on Auditing Standards) as well as having received
and discussed the written disclosures and the letter from Crowe Chizek required
by Independence Standards Board Statement No. 1 (Independence Discussions with
Audit Committees). Based on the review and discussions with management and Crowe
Chizek, the committee has recommended to the board that the audited financial
statements be included in our annual report on Form 10-K for the fiscal year
ending December 31, 2003 for filing with the Securities and Exchange Commission.

                                Audit Committee:
                           I.J. Reinhardt, Jr. (Chair)
                               Walter E. Breipohl
                                 Robert J. Doty


Audit Committee Financial Expert

While the board of directors endorses the effectiveness of our audit committee,
its membership does not include a director who qualifies for designation as an
"audit committee financial expert" - a new concept under federal regulation that
contemplates such designation only when an audit committee member satisfies all
five qualification requirements, such as experience (or "experience actively
supervising" others engaged in), preparing, auditing, analyzing or evaluating
financial statements presenting a level of accounting complexity comparable to
what is encountered in connection with our Company's financial statements.

                                       15.


                  STOCKHOLDER PROPOSALS FOR 2005 ANNUAL MEETING

For inclusion in our proxy statement and form of proxy relating to the 2005
annual meeting of stockholders, stockholder proposals must be received by us on
or before November 24, 2004. In order to be presented at such meeting, notice of
the proposal must be received by UnionBancorp on or before March 28, 2005, and
must otherwise comply with our bylaws.

                        "HOUSEHOLDING" OF PROXY MATERIALS

In December of 2000, the Securities and Exchange Commission adopted new rules
that permit companies and intermediaries (e.g., brokers) to satisfy the delivery
requirements for proxy statements, prospectuses and annual reports with respect
to two or more security holders sharing the same address by delivering a single
copy of proxy statements, prospectuses and annual reports, as the case may be,
addressed to those security holders. This process, which is commonly referred to
as "householding," potentially means extra convenience for security holders and
cost savings for companies.

This year, a number of brokers with accountholders who are UnionBancorp
stockholders will be "householding" our proxy materials. As indicated in the
notice previously provided by these brokers to UnionBancorp stockholders, a
single proxy statement and annual report will be delivered to multiple
stockholders sharing an address unless contrary instructions have been received
from an affected stockholder. Once you have received notice from your broker or
the Company that they will be "householding" communications to your address,
"householding" will continue until you are notified otherwise or until you
revoke your consent. If, at any time, you no longer wish to participate in
"householding" and would prefer to receive a separate proxy statement and annual
report, please notify your broker, direct your written request to UnionBancorp,
Inc., Investor Relations, 321 West Main Street, Ottawa, IL 61350 or contact
Investor Relations at (815) 431-2720.

Stockholders who currently receive multiple copies of the proxy statement and
annual report at their address and would like to request "householding" of their
communications should contact their broker or, if a stockholder is a direct
holder of UnionBancorp shares, they should submit a written request to
Computershare Investor Services, the Company's transfer agent, at 2 North
LaSalle Street, Chicago, IL 60602.

                                  OTHER MATTERS

We do not intend to present any other business at the meeting and know of no
other matters which will be presented. However, if any other matters come before
the meeting, it is the intention of the persons named in the accompanying proxy
to vote in accordance with their best judgment on those matters. A
representative of our independent auditors, Crowe, Chizek and Company, LLC, is
expected to attend the annual meeting and will be available to respond to
appropriate questions and to make a statement if he or she so desires.

Your proxy is solicited by the board of directors, and we will pay the cost of
solicitation. In addition to soliciting proxies by use of the mail, officers,
directors and regular employees of UnionBancorp or our subsidiaries, acting on
our behalf, may solicit proxies by telephone, telegraph or personal interview.
We will, at our expense, upon the receipt of a request from brokers and other
custodians, nominees and fiduciaries, forward proxy soliciting material to the
beneficial owners of shares held of record by such persons.

                                       16.


                           FAILURE TO INDICATE CHOICE

If any stockholder fails to indicate a choice with respect to any of the
proposals on the proxy for the annual meeting, the shares of such stockholder
shall be voted FOR the nominees listed under proposal 1.

                               UNIONBANCORP, INC.
                             AUDIT COMMITTEE CHARTER


I.       PURPOSE

The purpose of the Audit Committee is to assist the Board of Directors:

         o        In its oversight of the Company's accounting and financial
                  reporting principles and policies and internal accounting and
                  disclosure controls and procedures;
         o        In its oversight and supervision of the Company's internal
                  audit function;
         o        In its oversight of the certification of the Company's
                  quarterly and annual financial statements and assessment of
                  internal disclosure controls by the Company's Chief Executive
                  Officer (CEO) and Chief Financial Officer (CFO);
         o        In its oversight of the Company's consolidated financial
                  statements and the independent external audit thereof,
                  including the appointing, compensating, overseeing (including
                  resolving any disagreements between management and the
                  independent external auditor regarding financial reporting),
                  evaluating and, where deemed appropriate, replacing the
                  registered independent external auditors (or appointing the
                  registered independent external auditors to be proposed for
                  shareholder ratifications in any proxy statement); and
         o        In evaluating the independence of the external auditors.

     The function of the Audit Committee is oversight. The management of the
     Company is responsible for the preparation, presentation and integrity of
     the Company's consolidated financial statements. Management is responsible
     for maintaining appropriate accounting and financial reporting principles
     and policies and internal accounting and disclosure controls and procedures
     designed to assure compliance with accounting standards and applicable laws
     and regulations.

     In fulfilling their responsibilities hereunder, it is recognized that
     members of the Audit Committee are not full-time employees of the Company
     and are not, and do not represent themselves to be, accountants or auditors
     by profession or experts in the fields of accounting or auditing. As such,
     it is not the duty or responsibility of the Audit Committee or its members
     to conduct "field work" or other types of auditing or accounting reviews or
     procedures or to set auditor independence standards. Each member of the
     Audit Committee shall be entitled to rely on:

              A.  The integrity of those persons and organizations within and
                  outside the Company from which it receives information,
              B.  The accuracy of the financial and other information provided
                  to the Audit Committee by such persons or organizations absent
                  actual knowledge to the contrary (which shall be promptly
                  reported to the Board of Directors), and representations made
                  by management as to any information technology, internal audit
                  and other non-audit services provided by the independent
                  external auditors to the Company.

     The independent external auditors are responsible for planning and carrying
     out a proper audit of the Company's annual consolidated financial
     statements and reviews of the Company's quarterly consolidated financial
     statements prior to the filing of each quarterly report on Form 10-Q, and
     other procedures.

                                       22.


                                                                       EXHIBIT B


     The independent external auditors for the Company are accountable to the
     Audit Committee. The Audit Committee has the authority and responsibility
     to select and evaluate the independent external auditors. The Audit
     Committee shall pre-approve all audit and non-audit services proposed to be
     provided by the Company's external auditors in compliance with section 202
     of the "Public Company Accounting Reform and Investor Protection Act of
     2002". The independent external auditors shall submit to the Company
     annually a formal written statement delineating all relationships between
     the independent external auditors and the Company ("Statement as to
     Independence"), addressing each non-audit service provided to the Company.
     The Audit Committee shall be responsible for considering whether any
     services provided by the external auditor would cause the external auditor
     to not be independent of the Company.

II.      COMPOSITION

The Audit Committee shall be comprised of at least three independent members of
the Board of Directors, each of whom shall have no relationship to the Company,
or to the executive officers of the Company or its subsidiaries or affiliates.

services performed for the Company other than compensation received for Board of
Directors and committee fees, and shall not be an affiliate of the Company or
any of its subsidiaries, as defined by the Securities and Exchange Commission

                      accounting estimates, accruals and reserves;
              C.  Experience with internal accounting controls; and

                                                                       EXHIBIT B


III.     MEETINGS

circumstances dictate. At least annually, the Audit Committee should meet
separately with the internal auditor and the independent external auditor,

privately.

Company's independent counsel, or independent external auditors to attend a
meeting of the Audit Committee or to meet with any members of or consultants to,
the Audit Committee.

                      disclosures included in the Company's periodic and annual
                      filings with the SEC, and consider whether the financial
                      statements and related disclosures accurately and
                      appropriately reflect their knowledge of the financial
                      condition of the Company and its results of operations.

                  2.  Accuracy of Financial Reports. The Audit Committee shall
                      require management to make all material correcting
                      adjustments to the Company's quarterly and annual
                      consolidated financial statements to be filed with the
                      SEC, that are identified by the independent external
                      auditor as being required by generally accepted accounting
                      principles ("GAAP") or the rules of the SEC.

                      quarterly basis, the Audit Committee shall inquire of
                      management as to whether they have complied with the SEC's
                      disclosure requirements regarding the Company's
                      requirement to disclose, in quarterly and annual SEC
                      filings, all material off-balance-sheet transactions,
                      arrangements, obligations (including contingent
                      obligations) and other relationships of the Company with
                      unconsolidated entities or other persons, that have a
                      material current or future effect on financial condition,
                      changes in financial condition, results of operations,

                      a quarterly basis, the Audit Committee shall inquire of
                      management as to whether they have complied with the SEC's

                      the Company's requirement to only disclose in SEC filings,
                      or in any public disclosures or press or other release,

                      untrue statement of a material fact or omit to state a
                      material fact necessary in order to make the pro forma
                      financial information, in light of the circumstances under
                      which it is presented, not misleading; and to reconcile
                      the pro forma financial information with the financial
                      condition and results of operations of the Company under
                      GAAP.

                                                                       EXHIBIT B

                      purchases and sales and stock issued due to exercises of
                      stock options. Also, the Audit Committee shall determine
                      that management has put in place procedures to report to
                      the SEC, within ten (10) business days, for any new
                      directors, officers or 10% stockholders of the Company,

                      and annual financial statements and disclosures, required
                      to be reported to the SEC, are accurate and complete. This

                      followed by management to comply with quarterly and annual

                                       25.


                                                                       EXHIBIT B


              B.  Independent External Auditor:

                  The Audit Committee is responsible for the appointment and/or
                  discharge of the Company's independent external auditor and
                  the Company's independent external auditor shall report
                  directly to the Audit Committee. The Audit Committee should
                  also pre-approve the compensation of the external auditor, and
                  evaluate the external auditor's independence. The Audit
                  Committee shall also pre-approve all permissible non-audit
                  services and fees to be provided by the Company's independent
                  external auditor. The pre-approval of audit and non-audit
                  services and fees of the independent external auditor may be
                  documented by a member of the Audit Committee signing annual
                  or periodic engagement letters that define in general terms
                  the type of services to be provided and the range of fees that
                  are considered acceptable for such services, or as otherwise
                  documented in the minutes of the Audit Committee meetings. The
                  actual compensation paid to the independent external auditor,
                  for all such pre-approved services and fees, are to be
                  reported to the Audit Committee by management on at least a
                  quarterly basis.

              C.  Internal and External Audit Plans:

                  The Audit Committee should review the annual audit plans of
                  the internal auditor and the independent external auditor,
                  including the degree of coordination of the respective plans.

                  The Audit Committee should inquire of the internal auditor and
                  independent external auditor as to the extent to which the
                  planned audit scope can be relied upon to detect material
                  misstatements in the consolidated financial statements and
                  other public disclosures, weaknesses in internal accounting
                  and disclosure controls, and fraud. Additionally, the Audit
                  Committee should inquire regarding the audit plans of the
                  internal auditor and independent external auditor regarding
                  electronic data processing and controls to ensure that such
                  plans address the related impact on financial risk and
                  internal controls.

              D.  External Audit Results:

                  The Audit Committee should review with management the results
                  of the independent external auditor's quarterly financial
                  statement reviews, and review with management and the
                  independent external auditor the results of the annual
                  financial statement audit. The Audit Committee should also
                  review with management and the independent external auditor
                  their assessment of the quality of the Company's accounting
                  principles, the adequacy of internal accounting and disclosure
                  controls and the resolution of identified significant
                  deficiencies or material weaknesses and reportable conditions
                  in internal accounting and disclosure controls. The Audit
                  Committee should also review compliance with laws and
                  regulations and other audit reports deemed significant by the
                  Committee. Based on this review, the Audit Committee shall
                  make its recommendation to the Board of Directors as to the
                  inclusion of the audited consolidated financial statements in
                  the Company's annual report on Form 10-K.

              E.  Annual Proxy Statement Disclosure:

                  The Audit Committee should report audit activities to the
                  Board of Directors and issue an annual report to be included
                  in the Company's proxy statement (including appropriate

                                       26.


                                                                       EXHIBIT B


                  oversight conclusions) for submission to the shareholders. In
                  addition, the Audit Committee should re-approve the Audit
                  Committee Charter, annually, with a copy of the charter filed
                  with the SEC every three (3) years, and after any amendments.

              F.  Independent External Auditor Communication With the Audit
                  Committee:

                  It is the independent external auditor's responsibility, as
                  required by generally accepted auditing standards, to make
                  certain communications to the Audit Committee on at least an
                  annual basis. Such matters include the independent external
                  auditor's responsibility under generally accepted auditing
                  standards, matters pertaining to the external auditor's
                  independence, selection of or changes in significant
                  accounting principles, management's judgments and significant
                  accounting estimates, significant audit adjustments posted or
                  uncorrected, the external auditors responsibility and
                  consideration of other information that accompanies the
                  audited consolidated financial statements, any disagreements
                  with management, any difficulties encountered during the
                  audit, any consequential illegal acts or irregularities, any
                  major issues discussed with management prior to retention of
                  the external auditors as auditors of the Company for the
                  current fiscal year, or instances of management consultation
                  with other accountants regarding significant accounting or
                  auditing matters, and any management advisory services and
                  fees provided by the independent external auditor.

              G.  Communication of Concerns of the Audit Committee With the
                  Independent External Auditor:

                  The Audit Committee shall be responsible for informing the
                  independent external auditor of any serious concerns regarding
                  to the accuracy and integrity of the Company's financial
                  reporting, any serious concerns regarding the honesty and
                  integrity of the Company's management, and any serious
                  concerns regarding the adequacy of the Company's internal
                  accounting and disclosure controls. In fulfilling these
                  responsibilities the Audit Committee is aware that it is
                  illegal for an officer or director of the Company to mislead
                  or lie to the independent external auditor.

              H.  Internal Audit Supervision:

                  The Audit Committee should review the appointment and
                  replacement of the outsourced internal audit service provider.
                  The outsourced internal audit service provider shall report
                  directly to the chairman of the audit committee, with
                  administrative oversight provided by the Risk Assessment
                  Officer of the Company. At least annually, the Audit Committee
                  should evaluate the effectiveness of the internal audit
                  function and consider the need to make changes to ensure that
                  the internal audit objectives are be met.

                  The Audit Committee should review and approve the annual
                  internal audit plans, monitor the completion of these plans,
                  and approve any changes to the annual plans. The Audit
                  Committee should review the periodic reports of internal audit
                  division activities, including the opinion of the outsourced
                  internal audit service provider regarding the adequacy of the
                  Company's internal accounting and disclosure control
                  structure. The Audit Committee should meet with the outsourced
                  internal audit service provider to discuss the status of
                  completion of the annual internal audit plans and the periodic
                  internal audit reports and to consider the need for further
                  audit follow-up and investigation.

                                       27.


                                                                       EXHIBIT B

                  2.  The confidential, anonymous submission by employees of the
                      Company of concerns regarding questionable accounting or
                      auditing matters. The Audit Committee shall also establish
                      procedures to ensure that no retaliation will be allowed
                      to occur against anyone who reports potential fraud or a
                      complaint in good faith.

              J.  Compliance Supervision:

                  The Audit Committee should review and approve the annual
                  internal compliance plans, monitor the completion of these
                  plans, and approve any changes to the annual plans. The Audit
                  Committee should review the periodic reports of compliance
                  activities, including the opinion of the Risk Assessment
                  Officer regarding the adequacy of the Company's compliance
                  structure. The Audit Committee should meet with the Risk

                  reports and to consider the need for further follow-up and
                  investigation.

              K.  New Accounting Pronouncements:

                  approach taken towards evaluating the internal control
                  structure, should be explained to the Audit Committee by
                  financial management, the internal auditor or the independent
                  external auditor.

              L.  Continuing Education for the Audit Committee:

                  The Audit Committee shall establish a program of regular
                  continuing education for all Audit Committee members to ensure
                  that they are properly equipped to fulfill their
                  responsibilities.

              M.  Legal Counsel:

                  The Audit Committee should meet regularly with the Company's
                  general in-house legal counsel and outside legal counsel, when
                  appropriate, to discuss legal matters that have a significant
                  impact on the Company's consolidated financial statements. An
                  assessment of the Company's legal liability should be reviewed
                  for any pending or threatened litigation, including
                  establishment of any appropriate reserves or financial
                  disclosures until the matter is adjudicated. The Audit

                  prior permission of the Board of Directors or its management
                  at the expense of the Company.

                                       28.
