                                 PROXY STATEMENT


                         Annual Meeting of Stockholders
                    To Be Held on Tuesday, February 28, 2006
                              --------------------



                               GENERAL INFORMATION

         This Proxy Statement is being furnished to the stockholders of
Headwaters Incorporated ("Headwaters"), in connection with the solicitation of
proxies on behalf of the Board of Directors of Headwaters (the "Board") for use
at Headwaters' Annual Meeting of Stockholders and any and all adjournments or
continuations thereof (the "Meeting"), to be held Tuesday, February 28, 2006,
starting at 2:00 p.m., Mountain Standard Time, at the Country Inn & Suites,
10499 South Jordan Gateway, South Jordan, Utah 84095, for the purposes set forth
in the accompanying Notice of Annual Meeting of Stockholders (the "Notice").
These materials will be first mailed to stockholders on or about January 25,
2006.


                            PURPOSE OF ANNUAL MEETING

         At the Meeting, stockholders will be asked: (1) to elect two Class III
directors of Headwaters to serve until the 2009 annual meeting, or until their
successors are duly elected and qualified; (2) to ratify the selection by the
Board of Directors of Ernst & Young LLP as independent auditors of Headwaters
for the fiscal year ending September 30, 2006; and (3) to transact such other
business as may properly come before the Meeting and any and all adjournments or
postponements thereof.

         The Board recommends a vote "FOR" each of the proposals. The Board
knows of no other matters that are likely to be brought before the Meeting. If
any other matters properly come before the Meeting, however, the person named in
the enclosed proxy, or his duly appointed substitute acting at the Meeting, will
be authorized to vote or otherwise act thereon in accordance with his judgment
on such matters.


                     QUORUM, VOTING RIGHTS AND OTHER MATTERS

         Headwaters' Common Stock, $.001 par value (the "Common Stock"), will be
entitled to vote at the Meeting. Only stockholders of record at the close of
business on Wednesday, January 11, 2006 (the "Record Date"), will be entitled to
notice of, and to vote at, the Meeting. As of the Record Date, there were
42,051,096 shares of Common Stock outstanding. Holders of Common Stock as of the
Record Date are entitled to one vote for each share held for each of the
proposals.

         The presence, in person or by proxy, of the holders of a majority of
the shares of the Common Stock entitled to vote is necessary to constitute a
quorum at the Meeting. Under Delaware law, an abstaining vote and a broker
"non-vote" are counted as present and are, therefore, included for purposes of
determining whether a quorum of shares is present at a Meeting. Broker
"non-votes" are not included in the tabulation of the voting results on the
election of directors or issues requiring approval of a majority of the shares
present or represented by proxy and entitled to vote at the Meeting and,
therefore, do not have an effect on the outcome of Proposals 1 or 2. A broker
"non-vote" occurs when a nominee holding shares for a beneficial owner does not
vote on a particular proposal because the nominee does not have the
discretionary voting instructions with respect to that item and has not received
instructions from the beneficial owner. Shares held by brokers who do not have
discretionary authority to vote on a particular matter and have not received
voting instructions from their customers are not counted or deemed to be present
or represented for purposes of determining whether stockholders have approved
that matter.

                                       1


         With respect to Proposal 1, a plurality of the votes duly cast is
required for the election of directors (i.e., the nominees receiving the
greatest number of votes will be elected). Abstentions are not counted for
purposes of the election of directors.

         With respect to Proposal 2 and any other matters (other than the
election of directors) on which stockholders of Headwaters are entitled to vote,
the affirmative vote of the holders of a majority of the stockholders' shares
present in person or represented by proxy at the meeting and entitled to vote,
is required. For the purpose of determining whether the stockholders have
approved matters other than the election of directors, abstentions are treated
as shares present or represented and voting, so abstaining has the same effect
as a negative vote. If stockholders hold their shares through a broker, bank or
other nominee and do not instruct them how to vote, the broker may have
authority to vote the shares.

         All shares of Common Stock represented by properly executed proxies
will, unless such proxies have previously been revoked, be voted in accordance
with the instructions indicated in such proxies. If no such instructions are
indicated, such shares will be voted in favor of (i.e., "FOR") the items listed
in the Notice.

         Any stockholder executing a proxy has the power to revoke such proxy at
any time prior to its exercise. A proxy may be revoked prior to exercise by (i)
filing with Headwaters a written revocation of the proxy, (ii) appearing at the
Meeting and casting a vote contrary to that indicated on the proxy, or (iii)
submitting a duly executed proxy bearing a later date.

         The cost of preparing, printing, assembling and mailing this Proxy
Statement and other material furnished to stockholders in connection with the
solicitation of proxies will be borne by Headwaters. In addition to the mail
solicitation of proxies, officers, directors, employees and agents of Headwaters
may solicit proxies by written communication, telephone or personal call. Such
persons are to receive no special compensation for any solicitation activities.
Headwaters will reimburse banks, brokers and other persons holding Common Stock
for their expenses in forwarding proxy solicitation materials to beneficial
owners of Common Stock.

         All stockholders who receive proxy materials will receive instructions
for voting by mail, telephone, or by using the internet.

granted during fiscal 2005 to the Named Executives.

- ------------------

(1)      All of these SARs vested at grant date and, with the exception of Mr.
         Benson's award, require a payment by grantees of $2.00 per SAR, payable
         over a 52-month period. The maximum gain that may be received for each
         of these SARs is limited to the fair market value of one share of
         Headwaters' common stock at the date of grant, or $31.97 per share.
(2)      These SARs vest over five years, with 20% vesting on May 1, 2005 and
         80% vesting from March 31, 2007 through March 31, 2010. These SARs are
         exercisable based on the achievement of performance criteria related to
         the economic growth or economic value added ("EVA") of Headwaters
         during the five-year period.
(3)      The percentages reflected in the table above were computed based on the
         total number of SARs and options granted in fiscal 2005, or 3,227,320.
(4)      The exercise prices shown equal the fair market value on the date of
         grant, which fair market value was determined by the closing price of
         the Common Stock as reported by the New York Stock Exchange.
(5)      The fair value of each SAR grant was determined using the
         Black-Scholes-Merton option pricing model (B-S-M model) and the
         following assumptions: expected stock price volatility of 30%,
         risk-free interest rates ranging from 3.8% to 4.25%, weighted average
         expected lives (beyond vest date) ranging from 3.5 years to 5 years and
         no dividend yield. For those SARs with an appreciation cap, a 24%
         reduction in value from the B-S-M output was used. For those SARs for
         which a payment is required, a $0.30 reduction in value from the B-S-M
         output was used. The B-S-M model was developed for use in estimating
         the fair value of traded options that have no vesting restrictions and
         are fully transferable. In addition, option valuation models require
         the input of certain subjective assumptions, including expected stock
         price volatility. Because Headwaters' stock options and SARs have
         characteristics significantly different from those of traded options,
         and because changes in the subjective input assumptions can materially
         affect their fair value, in management's opinion, the existing models
         do not necessarily provide a reliable measure of the fair value of
         stock options or other stock-based compensation.

Aggregated Option/SAR Exercises in Fiscal 2005 and Fiscal Year-End
Option/SAR Values

         The following table summarizes for the Named Executives the number of
stock options exercised during fiscal 2005, the aggregate dollar value realized
upon exercise, the total number of unexercised options and SARs held at
September 30, 2005 and the aggregate dollar value of in-the-money unexercised
options and SARs held at September 30, 2005. Value realized upon exercise is the
difference between the fair market value of the underlying stock on the exercise
date (based upon the average of the high and low prices of Common Stock as
reported by the Nasdaq National Market for exercises prior to April 6, 2005, or
the New York Stock Exchange for exercises on or subsequent to April 6, 2005) and
the exercise price of the option. Options and SARs are in-the-money if the fair
market value of the underlying securities exceeds the exercise price of the
option or SAR. The value of unexercised, in-the-money options and SARs at
September 30, 2005 is the aggregate amount of the difference between their
exercise price and $37.40 per share, the fair market value of the underlying
stock on September 30, 2005, based on the closing price of the Common Stock on
that date. The underlying options and SARs have not been and may never be
exercised. The actual gains, if any, on exercise will depend on the value of the
Common Stock on the actual date of exercise. There can be no assurance that
these values will be realized.

Kirk A. Benson ...........         25,000                   March 2010

         In August 2005, in connection with the negotiation of Mr. Benson's
employment agreement with Headwaters, the Compensation Committee approved the
issuance of up to 25,000 shares of Common Stock to Mr. Benson, which shares will
vest in March 2010 if the market value of a share of Headwaters' Common Stock
meets or exceeds stipulated thresholds. The entire 25,000 shares would be issued
if the stock price is at least $60.00 as of March 31, 2010. The fair value of
this "contingent performance stock" was $975,000 and was estimated by an
independent valuation firm by calculating the probabilities that Headwaters'
common stock would reach the various market value thresholds.

Acceleration of Vesting of Options in Fiscal 2005

         In May 2005, the Compensation Committee of the Board of Directors
("Compensation Committee") approved the acceleration of vesting of options for
the purchase of approximately 1,059,000 shares of Common Stock for 138 officers,
directors and employees which were not fully vested as of the date of
acceleration (prior to acceleration, there were in total unvested outstanding
options to purchase approximately 1,291,000 shares). Options for which vesting
was accelerated consisted of all options with an exercise price equal to or
greater than $21.29 per share and all but 172,000 of the options accelerated
were "in the money" at the date of acceleration. Of the options accelerated,

                                       6


options to purchase a total of 188,098 shares of common stock were held by the
Named Executives, as follows: Mr. Benson - 60,000, Mr. Stewart - 32,523, Mr.
Hatfield - 20,270, Mr. Frailey - 31,306, and Mr. Lewis - 43,999. Compensation
expense totaling approximately $1,500,000 was recognized related to the
acceleration of vesting of options held by the Named Executives.

Stock Option and Stock Incentive Plans

         1995 Stock Option Plan. A total of 2,400,000 shares of Common Stock are
reserved for issuance under the 1995 Stock Option Plan (the "1995 Plan"). A
committee of Headwaters' Board of Directors (the "Committee"), or in its
absence, the Board, administers and interprets the 1995 Plan. This Committee was
authorized to grant options under the terms of the 1995 Plan to eligible
employees and consultants and to grant options and other awards outside the 1995
Plan to eligible employees, officers, directors, and consultants of Headwaters.
The 1995 Plan expired in 2005 and awards can no longer be granted. The 1995 Plan
provided for the granting of both incentive stock options ("ISOs") and
nonstatutory stock options ("NSOs"). Terms of options granted under the 1995
Plan, including vesting requirements, were determined by the Committee. Options
granted under the 1995 Plan vested over periods ranging from zero to ten years,
expire not later than ten years from the date of grant and are not transferable
other than by will or by the laws of descent and distribution. ISO grants were
required to meet the requirements of the Internal Revenue Code and could be made
only to employees of Headwaters.

         2002 Stock Incentive Plan. In April 2002, the Board of Directors
adopted the 2002 Stock Incentive Plan (the "2002 Plan"). The number of shares
reserved under the 2002 Plan is currently 850,000. NSOs, restricted stock, SARs
and stock units may be granted under the 2002 Plan. ISOs may not be granted
under the 2002 Plan. Employees, directors and consultants of Headwaters are
eligible for awards under the 2002 Plan, which expires ten years after adoption
unless terminated earlier by the Board. The administration of the 2002 Plan is
generally consistent with the administration of the 1995 Plan.

         2003 Stock Incentive Plan. In January 2003, the Board of Directors
adopted the 2003 Stock Incentive Plan (the "2003 Plan"). The 2003 Plan was
approved by Headwaters' stockholders at the 2003 annual meeting. In January
2004, the Board of Directors approved Amendment No. 1 to the 2003 Plan, which
increased the number of shares available for award grants to 2,500,000.
Amendment No. 1 to the 2003 Plan was approved by Headwaters' stockholders at the
2004 annual meeting. ISOs, NSOs, restricted stock, SARs and stock units may be
granted under the 2003 Plan. Employees, directors and consultants of Headwaters
are eligible for awards under the 2003 Plan, which expires ten years after
adoption unless terminated earlier by the Board. The administration of the 2003
Plan is generally consistent with the administration of the 1995 and 2002 Plans.

         Long Term Incentive Compensation Plan. In January 2005, the Board of
Directors adopted the Long Term Incentive Compensation Plan (the "LTIP"). The
LTIP was approved by Headwaters' stockholders at the 2005 annual meeting. The
total number of shares of Common Stock available for issuance pursuant to awards
over the entire term of the LTIP (through March 1, 2015) is 1,500,000. The LTIP
authorizes the grant of several types of awards, including ISOs, NSOs, SARs,
restricted stock and restricted stock unit awards, performance stock and
performance unit awards, unrestricted stock awards, cash awards and other
performance awards. Most awards under the LTIP are subject to a minimum service
vesting requirement of at least three years. There are also annual limits on
certain types of awards and on the number of awards that can be granted to a
single participant in any calendar year. The administration of the LTIP is the
responsibility of the Compensation Committee.

         Other Options. In addition to options granted under the above-described
plans, Headwaters has periodically granted options for the purchase of Common
Stock to employees, officers, directors and consultants outside those plans that
were not qualified as ISOs for tax purposes. There were 307,000 such option
grants during fiscal 2004, all of which were granted to employees of one of the
companies acquired by Headwaters in 2004.

         No Loans for Option Exercises. It is the policy of Headwaters to not
make loans to employees for the purpose of paying for the exercise of stock
options.

         Stockholder Approval of Equity Compensation Plans. The following table
presents information as of September 30, 2005 about Headwaters' Common Stock
that may be issued upon the exercise of options, SARs and other equity-based
awards granted to employees, consultants or members of the Board of Directors
under all of Headwaters' existing equity compensation plans and individual
arrangements. As described above, Headwaters has four primary stock option and
stock incentive plans under which options and other awards have been granted.
Headwaters has also issued options not covered by any plan. The 1995 Plan, the

                                       7


2003 Plan and the LTIP have been approved by stockholders. The 2002 Plan has not
been approved by stockholders. The amounts included in the caption "not approved
by stockholders" in the table below represent amounts applicable under (i) the
2002 Plan plus (ii) all stock options granted outside of any plan.

2000 Employee Stock Purchase Plan

         The Board approved the 2000 Employee Stock Purchase Plan ("ESPP") in
May 2000 to provide eligible employees with an opportunity to increase their
proprietary interest in Headwaters by purchasing Common Stock on favorable terms
and to pay for such purchases through payroll deductions. The Board has
subsequently amended the ESPP, most recently in May 2005. The ESPP was approved
by stockholders in September 2000.

         Substantially all employees of Headwaters are eligible to participate
in the ESPP after three months of employment. Non-employee directors are not
eligible. A total of 500,000 shares of common stock were initially reserved for
issuance under the Plan, and approximately 240,000 shares remain available for
future issuance as of September 30, 2005. Under the ESPP, employees purchase
shares of stock directly from Headwaters, which shares are made available from
treasury shares which have been repurchased on the open market. The ESPP is
intended to comply with Section 423 of the Internal Revenue Code, but is not
subject to the requirements of ERISA. Employees purchase stock through payroll
deductions of 1% to 10% of cash compensation, subject to certain limitations.
The stock is purchased in a series of quarterly offerings. The cost per share to
the employee is 85% of the fair market value at the end of each offering period.

         Participation in the ESPP is voluntary and each eligible employee will
make his or her own election whether and to what extent to participate in the
ESPP. It is therefore not possible to determine the benefits or amounts that
will be received in the future by individual employees or groups of employees,
including the Named Executives.

Incentive Bonus Plan

         The Board approved the Short Term Incentive Bonus Plan ("IBP") in
January 2005, the specifics of which are approved annually by the Compensation
Committee, the administrator of the plan. The IBP provides for annual cash
bonuses to be paid if Headwaters accomplishes certain financial goals and if
participating employees meet individual goals. Headwaters' financial goals are
based upon an economic value added concept ("EVA") that attempts to more closely
align with a company's share price performance than other measurements of
performance. The IBP was approved by stockholders in March 2005.

         Under the terms of the IBP, annual cash awards can be earned by
participants selected by the Compensation Committee who are employed at the end
of the fiscal year, provided Headwaters' and the participant's individual goals
are met or exceeded. Participants in the IBP are selected based on their roles
and responsibilities at Headwaters. The amount of the cash awards is dependent
on several factors, the most important of which is the EVA multiplier, or a
factor determined by how much Headwaters' performance meets or exceeds a
financial threshold ("EVA target") established by the Compensation Committee for
each fiscal year. No awards are earned if the minimum EVA target is not
achieved. EVA profit, which varies from traditional accrual accounting earnings,
is determined each fiscal year and is then compared to the EVA target, which
determines the EVA multiplier. EVA profit is defined as net income, plus
interest expense, plus or minus economic adjustments, minus the cost of capital.

         A portion of annual cash awards "earned" by certain management
personnel are "banked," meaning that the full amount of the awards is not
actually earned and paid unless the EVA target is achieved in each of the two
succeeding fiscal years. This banking mechanism helps motivate management and
employees to achieve long-term sustainable stockholder value and discourages
short-term performance at the expense of long-term stockholder value creation.
The bonus amounts for 2003 in the Summary Compensation Table represent the cash
awards paid to the Named Executives for fiscal 2003, and include 50% of the

                                       8


banked amounts from fiscal 2001 and fiscal 2002, which were earned in 2003. The
bonus amounts for 2004 in the Summary Compensation Table represent the cash
awards paid to the Named Executives for fiscal 2004, and include 50% of the
banked amounts from fiscal 2002 and fiscal 2003, which were earned in 2004. The
bonus amounts for 2005 in the Summary Compensation Table represent the cash
awards paid to the Named Executives for fiscal 2005, and include 50% of the
banked amounts from fiscal 2003 and fiscal 2004, which were earned in 2005.

         The total bonus amounts for fiscal 2003, 2004 and 2005 for all officers
and employees under all bonus plans of Headwaters or its acquired subsidiaries,
and including discretionary bonus payments approved by the Compensation
Committee, was $5,005,737, $14,051,890, and $20,268,361, respectively.

Deferred Compensation Plan

         In November 2004, Headwaters' Board of Directors approved a
nonqualified Deferred Compensation Plan ("DCP") for certain designated officers
and employees, which became effective on January 1, 2005. The DCP is a deferred
compensation plan that is not qualified under Section 401(a) of the Internal
Revenue Code and that is limited to a select group of management employees and
highly compensated employees of Headwaters and its subsidiaries. All of the
Named Executives are eligible to participate in the DCP. Participants in the DCP
can annually elect to defer up to 50% of base salary and up to 100% of incentive
compensation into the Plan. Participant deferrals are matched by Headwaters at a
rate of 50% of the first six percent of salary or incentive compensation
deferred less any match made through the Headwaters 401(k) Savings and
Investment Plan. Matching contributions are fully vested after three years of
service. Participants direct the investment of deferred compensation and the
company match, selecting from a series of investment options that are similar to
the Headwaters 401(k) Plan. The DCP is funded through a "rabbi trust" and
trust-owned life insurance on Plan participants. The Plan is intended to meet
all applicable regulatory requirements, including Section 409A of the Internal
Revenue Code.

Employment Contracts and Termination of Employment and Change in Control
Arrangements

         Kirk A. Benson. In August 2005, Headwaters and Mr. Benson entered into
an employment agreement covering Mr. Benson's "at will" employment for the
5-year period commencing April 1, 2005 through March 31, 2010. The agreement
calls for payment of a gross annual salary of $600,000 for the 12-month period
ending March 31, 2006, $650,000 for the 12-month period ending March 31, 2007,
$700,000 for the 12-month period ending March 31, 2008, $750,000 for the
12-month period ending March 31, 2009, and $800,000 for the 12-month period
ending March 31, 2010. The employment agreement further provides for
participation in Headwaters' IBP and LTIP, the grant of 25,000 shares of
contingent performance stock previously described, severance pay, and other
standard benefits such as vacation, participation in Headwaters' employee
benefit plans and reimbursement for certain stipulated fees and expenses and
necessary and reasonable business expenses.

         Upon termination of his employment, Headwaters and Mr. Benson will
enter into a consulting agreement requiring no more than 20% of Mr. Benson's
time for a three-year period, for which Mr. Benson will receive remuneration
totaling $500,000. If Headwaters terminates Mr. Benson's employment without
cause or if Mr. Benson resigns all of his positions with Headwaters for good
reason, as defined in his employment agreement (including as a result of certain
change in control circumstances), he is entitled to termination benefits equal
to 300% of his annual base salary in effect when his employment terminates. In
the event of such termination, i) all of Mr. Benson's outstanding options, SARs
and restricted stock shall immediately become fully vested and exercisable, ii)
Mr. Benson will be paid a prorated bonus calculated under the provisions of the
fiscal year's IBP arrangements then in effect, and iii) Mr. Benson will be paid
for any "banked" amounts under the provisions of previous fiscal years' IBP
arrangements.

         Steven G. Stewart. Effective May 1998, Headwaters and Mr. Stewart
entered into an employment agreement covering a continuous three-year period,
unless terminated by Headwaters for cause or disability, or by Mr. Stewart for
good cause or without good reason provided 90 days prior written notice is
given. In October 2005, Headwaters and Mr. Stewart entered into an employment
transition agreement that superseded the terms of the employment agreement. The
employment transition agreement provides for Mr. Stewart's continued employment
with Headwaters in the position of Treasurer through March 31, 2006 and as an
employee through March 31, 2009. According to the terms of the agreement, Mr.
Stewart receives compensation as follows: during the period October 1, 2005
through March 31, 2006 at the rate of $24,300 per month; during the period April
1, 2006 through September 30, 2006 at the rate of $15,000 per month; and during
the period October 1, 2006 through March 31, 2009 at the rate of $10,000 per
month. In addition, the agreement calls for i) a bonus payment for fiscal 2006
at the rate of 50% of what would otherwise be paid under terms of Headwaters'
IBP; ii) a severance payment of $583,000 called for by the original employment
agreement; iii) a cash payment of $400,000 in lieu of participation in the

                                       9


long-term incentive compensation awarded to executive officers in 2005; and iv)
the grant of 6,500 shares of restricted stock, which vest over a two-year period
ending November 2007, provided Mr. Stewart remains employed during that period.

         Michael S. Lewis. In connection with the purchase of Eldorado Stone in
June 2004, Headwaters entered into an employment agreement with Mr. Lewis. The
employment agreement has an initial three-year term and subsequently remains in
effect for one-year periods unless terminated by notice by either party. The
agreement calls for an initial annual salary of $225,000, with an increase to
$250,000 in October 2004. Thereafter Mr. Lewis' salary is to be reviewed
annually and increased at the same time other executives' salaries are
increased. Mr. Lewis' current annual salary is $259,459. In addition, the
agreement calls for i) Mr. Lewis' participation in Headwaters' bonus plan; ii)
the grant of options to purchase 30,000 shares of Common Stock, which grant was
made in June 2004; iii) the grant of 3,267 shares of restricted stock, vesting
through March 2009, which grant was also made in June 2004; iv) payment of
"stay-put" bonuses of $300,000 on September 30, 2005 and $350,000 on September
30, 2006, provided that Mr. Lewis is still employed on those dates; and v) other
standard benefits such as vacation, a car allowance, participation in
Headwaters' employee benefit plans and reimbursement for necessary and
reasonable business expenses. Upon termination of employment by Mr. Lewis for
good reason, as defined, or upon termination by Headwaters without cause,
Headwaters has agreed to pay Mr. Lewis a severance allowance at his then current
annual salary for a period of 18 months plus i) the full amount of the bonus
under the IBP which would otherwise have been paid during the severance period,
and ii) a prorated amount of the stay-put bonus, if applicable.

         Scott K. Sorensen. In connection with Mr. Sorensen's appointment as
Chief Financial Officer on October 1, 2005, Headwaters provided Mr. Sorensen an
Offer of Employment and the parties entered into an Executive Severance
Agreement. The significant terms of Mr. Sorensen's employment arrangements
pursuant to these two agreements include an annual salary of $290,000,
participation in Headwaters' IBP and other benefit plans available to
Headwaters' executives and employees, a grant of 100,000 SARs under terms of
Headwaters' 2003 Plan and LTIP (which grant was made in September 2005), and
under certain circumstances, and only if termination occurs within 12 months of
employment, severance pay equal to salary earned during the period of
employment, not to exceed 12 months of salary.

independent directors periodically meet in executive session, without
management, as part of the agenda for Board meetings. Mr. Herickhoff, an
independent director and Vice Chairman of the Board, chairs all executive
session meetings of directors.

         o        E-mailing to the Audit Committee at
                  headwaters-hotline@blackbearventures.com, or

                                       11

         The Corporate Secretary will forward any communications related to
Headwaters' accounting, internal accounting controls, or auditing matters to the

Board and Committee Meetings

         The Board held a total of six meetings during fiscal 2005. All
directors attended all of the meetings, except for one director who attended
five meetings. Headwaters encourages but does not require Board member
attendance at the Headwaters' annual meeting. Two directors attended the 2005
annual meeting.

          The Board currently has three committees, a Nominating and Corporate
Governance Committee, an Audit Committee, and a Compensation Committee. The
Nominating and Corporate Governance Committee currently consists of Mr.
Dickinson, as chair, Mr. Garn, and Mr. Herickhoff. The Nominating and Corporate
Governance Committee held four meetings in fiscal 2005. The Audit Committee
currently consists of Mr. Christensen, as chair, Mr. Fisher, Mr. Garn, and Mr.
Malquist. The Audit Committee held nine meetings in fiscal 2005. The
Compensation Committee currently consists of Mr. Herickhoff, as chair, Mr.
Fisher and Mr. Malquist. The Compensation Committee held six meetings in fiscal
2005. Each director attended at least 75% of all applicable committee meetings.

Nominating and Corporate Governance Committee Report

         The Nominating and Corporate Governance Committee provides assistance
to the Board in overseeing corporate governance, evaluates and selects director
nominees of the Company to be considered for election at the annual meeting of
stockholders and takes such other actions within the scope of its charter as the
committee deems necessary or appropriate. A copy of the committee's current
charter is attached to this proxy statement as Appendix A.

         The Nominating and Corporate Governance Committee has responsibility
for identifying and evaluating new nominees to the Board. In evaluating director
nominees, the committee will, as described in the committee's charter, consider
various criteria, including relevant industry experience, general business
experience, relevant financial experience, and compliance with independence and
other qualifications necessary to comply with any applicable tax and securities
laws and the rules and regulations of the New York Stock Exchange. In addition,
directors must have time available to devote to Board activities and to enhance
their knowledge of Headwaters' business. Headwaters therefore seeks to attract
and retain highly qualified directors who have sufficient time to devote to
their substantial responsibilities and duties to Headwaters and its
stockholders.

         In accordance with company's Corporate Governance Guidelines, the Board
is comprised of three tiers of members with staggered three-year terms. One tier
of members is elected each year by Headwaters' stockholders at the annual
meeting. Between annual meetings of stockholders, the Board may elect directors
to serve until the next annual meeting. Nominees for directorship will be
selected by the Nominating and Corporate Governance Committee, in accordance
with the policies and principles in its charter, and nominated by the Board for
stockholder elections. To date, Headwaters has not engaged third parties to
identify or evaluate or assist in identifying potential director nominees,
although Headwaters may do so in the future.

         To date, Headwaters has not received any recommendations from
stockholders requesting the Board or any of its committees to consider a nominee
for inclusion among the Board's slate of nominees in Headwaters' proxy statement
for its annual meeting. However, Headwaters' stockholders may recommend director
nominees, and the committee will consider nominees recommended by stockholders.
A stockholder wishing to submit such a recommendation should send a letter to
the Corporate Secretary at Headwaters' principal executive offices in accordance
with the provisions of Headwaters' Bylaws and the provisions set forth herein
under the heading "Stockholder Proposals." The mailing envelope must contain a
clear notation indicating that the enclosed letter is a "Director Nominee
Recommendation." The letter must identify the author as a stockholder and
provide a brief summary of the nominee's qualifications, including such
information about the nominee as would have been required to be included in a

                                       12


proxy statement filed pursuant to the rules of the SEC had such nominee been
nominated by the Board, as well as contact information for both the nominee and
the stockholder. Nominees should at a minimum have relevant business and
financial experience and must be able to read and understand fundamental
financial statements. Headwaters anticipates that nominees recommended by
stockholders will be evaluated in the same manner as nominees recommended by
anyone else, although, the committee may prefer nominees who are personally
known to the existing directors and whose reputations are highly regarded. The
committee will consider all relevant qualifications as well as the needs of
Headwaters in terms of compliance with New York Stock Exchange listing standards
and SEC rules.

         All of the nominees for directors being voted upon at the Meeting are
directors standing for reelection.

         The Nominating and Corporate Governance Committee assisted the Board
and each of its committees in conducting self-evaluations of their functioning

Audit Committee Report

         The Audit Committee oversees Headwaters' financial reporting process on
behalf of the Board. Headwaters' management has the primary responsibility for
the financial statements, for maintaining effective internal control over
financial reporting, and for assessing the effectiveness of internal control
over financial reporting. In fulfilling its oversight responsibilities, the
committee reviewed and discussed the audited consolidated financial statements
with Headwaters' management, including a discussion of the quality, not just the
acceptability, of the accounting principles used; the reasonableness of
significant judgments made; and the clarity of the disclosures in the financial
statements.

         The Audit Committee reviewed with Ernst & Young LLP, Headwaters'
auditor, which is responsible for expressing an opinion on the conformity of the
consolidated financial statements with U.S. generally accepted accounting
principles, its judgments as to the quality, not just the acceptability, of
Headwaters' accounting principles and such other matters as are required to be
discussed with the committee by Statement on Auditing Standards No. 61, other
standards of the Public Company Accounting Oversight Board, rules of the
Securities and Exchange Commission and other applicable regulations. In
addition, the committee has discussed with Ernst & Young the firm's independence
from Headwaters, including the matters in the letter from Ernst & Young required
by Independence Standards Board Standard No. 1, and considered the compatibility
of non-audit services with Ernst & Young's independence.

         The Audit Committee also reviewed management's report on its assessment
of the effectiveness of Headwaters' internal control over financial reporting
and Ernst & Young's report on management's assessment and the effectiveness of
Headwaters' internal control over financial reporting.

         The Audit Committee discussed with Headwaters' internal auditors and
Ernst & Young the overall scope and plans for their respective audits. The
committee regularly meets with the internal auditors and Ernst & Young, with and
without management present, to discuss the results of their examinations; their
evaluations of Headwaters' internal control, including internal control over
financial reporting; and the overall quality of Headwaters' financial reporting.

         In reliance on the reviews and discussions referred to above, the Audit
Committee recommended to the Board, and the Board approved, that the audited
consolidated financial statements and management's assessment of the
effectiveness of Headwaters' internal control over financial reporting, together
with Ernst & Young's reports thereon, be included in Headwaters' Annual Report
on Form 10-K for the fiscal year ended September 30, 2005 filed with the
Securities and Exchange Commission. The committee and the Board also have
recommended, subject to stockholder approval, the selection of Ernst & Young LLP
to audit Headwaters' 2006 consolidated financial statements.

         The Audit Committee acts pursuant to a written charter that was
approved by the Board of Directors, a current copy of which is attached to this
proxy statement as Appendix B.

Compensation Committee Report on Executive Compensation

         The Board amended the Compensation Committee charter in March 2005, a
current copy of which is attached to this proxy statement as Appendix C. The
Compensation Committee reviews and makes recommendations to the Board of
Directors concerning the overall compensation for Headwaters' officers and other
key executives, including the Named Executives. The committee also oversees the
granting of stock options, restricted stock, SARs, other equity-based
compensation and the payment of incentive bonuses to all executives and
employees of Headwaters. Future compensation polices will be dependent on
Headwaters' performance and cash flow and employee performance.

         Headwaters seeks to compensate executives at competitive levels,
considering current compensation surveys and practices for companies in similar
industries and development patterns, the growth of Headwaters, each executive's
individual contribution to meeting Headwaters' goals and objectives, and overall
business conditions, as part of the total benefit package for employees.

         Headwaters' compensation practices include long-term incentives such as
stock option, restricted stock and SAR grants as well as a bonus plan. The
committee believes that an incentive bonus program that closely links bonus
compensation to the creation of stockholder value as measured under the EVA
concept is in the best interests of Headwaters and its stockholders since the
committee believes that EVA-based plans are one of the best indicators of actual
stockholder value creation. Accordingly, the Board adopted a formal EVA-based
incentive bonus plan in fiscal 2000. The Board determined that such a plan was
the best way to motivate Headwaters' management and employees to continuously
seek to meet and exceed performance goals. The incentive bonus plan is deemed to
be a significant part of the total compensation package for the Named
Executives.

         The current employment agreement for Mr. Benson was approved by the
Compensation Committee in August 2005. The Compensation Committee recommended
the fiscal 2005 cash compensation, cash bonus and grant of SARs and contingent
performance stock to Mr. Benson based on Mr. Benson's ability to meet
Headwaters' objectives.

         Section 162(m) of the Code limits Headwaters' tax deduction of certain
compensation in excess of $1 million paid to certain executive officers named in
the proxy unless the compensation is performance-based. Compensation
attributable to equity-based compensation granted under the 1995 Plan and the
2003 Plan is treated as performance-based compensation if (1) the awards are
granted by the Compensation Committee; (2) the Plans restrict the number of
shares for which awards may be granted to an executive during a specified
period; and (3) the awards have an exercise price at least equal to the fair
market value of a share of Common Stock on the date of grant. Grants of
restricted stock under the 2003 Plan and awards under the 2002 Plan are not
considered performance-based compensation.

         While the tax impact of any compensation arrangement is one factor to
be considered, such impact is evaluated in light of the Compensation Committee's
overall compensation philosophy. The Compensation Committee intends to establish
executive officer compensation programs which will maximize Headwaters' tax
deductions, if the Compensation Committee determines that such actions are
consistent with its philosophy and in the best interests of Headwaters and its
stockholders. From time to time, the committee may award compensation that is
not fully tax deductible if the committee determines that such award is
consistent with its philosophy and in the best interests of Headwaters and its
stockholders.

                                       14


         The Compensation Committee strives to ensure that Headwaters'
compensation plan attracts, retains and rewards both staff and management
personnel while continuing to operate in the best interests of Headwaters and
its stockholders.

Compensation Committee Interlocks and Insider Participation

         No interlocking relationship exists between the Board of Directors or
Compensation Committee and the Board of Directors or Compensation Committee of
any other entity, nor has any interlocking relationship existed in the past.

Compensation of Directors

         Headwaters' directors hold office until the end of their respective
terms or until their successors have been duly elected and qualified.
Headwaters' executive officers are appointed by the Board of Directors and serve
at the discretion of the Board.

         All outside directors are entitled to base annual cash compensation of
$50,000, which is paid quarterly. The following additional annual compensation
is also paid quarterly: Vice Chair of the Board, $15,000; Chair of the Audit
Committee, $15,000; and all other committee chairs, $10,000. The outside
directors also receive options for the purchase of Common Stock which normally
vest at the rate of 12,000 shares each year. However, in 2005, due to the
acceleration of vesting of options held by any optionee with an exercise price
equal to or greater than $21.29 per share, 144,000 options held by directors
vested in fiscal 2005 that would otherwise have vested in fiscal 2006, 2007 and
2008. Directors receive reimbursement for out-of-pocket expenses. The cash
compensation and options described in this section do not apply to directors who
are salaried employees of Headwaters.

         In January and March 2003, Messrs. Christensen, Dickinson, and Malquist
were each granted options to purchase a total of 36,000 shares of Common Stock
at exercise prices equal to the closing price of the Common Stock on the grant
dates. These options vested ratably in December 2003, 2004 and 2005 and were
granted under the 1995 Plan, the 2002 Plan, and the 2003 Plan. In 2004, Messrs.
Herickhoff, Fisher, Garn, and Weller were each granted options to purchase a
total of 36,000 shares of Common Stock at exercise prices equal to the closing
price of the Common Stock on the grant date. These options, which were granted
under the 2003 Plan, were originally set to vest ratably in December 2005, 2006
and 2007, but due to the acceleration of vesting described above, were vested in
May 2005.

Stockholder Return Performance Graph

         The following graph shows a comparison of the cumulative total
stockholder return, calculated on a dividend reinvestment basis, for September
30, 2000 through September 30, 2005, on Headwaters' Common Stock with (1) the
New York Stock Exchange Composite Index, (2) the Nasdaq Composite Index - U.S.,
(3) the Standard & Poors - 500 Energy Sector Index, and (4) the Standard & Poors
- - 500 Building Products Index. The comparison assumes $100 was invested on
September 30, 2000. Headwaters' Common Stock traded on the Nasdaq National
Market until April 6, 2005, at which time it began trading on the New York Stock
Exchange. Accordingly, indices for both the Nasdaq National Market and the New
York Stock Exchange are presented.

         Please note that historic stock price performance shown on the graph is
not necessarily indicative of future price performance. Headwaters has not paid
dividends on its Common Stock.

                        TRANSACTIONS WITH RELATED PARTIES

         Employment and Related Agreements. As of September 30, 2005, Headwaters
had employment agreements with Messrs. Benson, Stewart, Lewis and Sorensen which
provide for significant benefits. See "Employment Contracts and Termination of
Employment and Change in Control Arrangements." As of September 30, 2005,
Headwaters and its subsidiaries have also entered into employment agreements
with 22 other officers and employees. The agreements have original terms ranging
up to five years, many of which are renewable by Headwaters, often for one-year
terms. Including the Named Executives, the agreements provide for annual
salaries as of September 30, 2005 which range from approximately $69,000 to
$600,000 annually per person. Assuming all agreements set to expire in 2006 are
renewed, the annual commitment under all employment agreements combined would
approximate $4,345,000. The aggregate commitment as of September 30, 2005,
assuming no renewals, is approximately $6,590,000. Most agreements provide for
termination benefits, which vary widely from agreement to agreement.

         Insurance Benefits. Headwaters purchases certain insurance benefits for
its employees from various insurance companies where Wansutter Employee Benefits
LLC acts as broker. Mr. Weller, a director, is a principal of Wansutter Employee
Benefits LLC. Commissions paid to that company by providers of insurance
services to Headwaters totaled approximately $120,000 in fiscal 2003, $130,000
in fiscal 2004 and $196,000 in fiscal 2005.

         Eldorado Stone Product. Eldorado Stone purchases product from an entity
located in Mexico in which Mr. Lewis has a minority ownership interest. Costs
incurred for materials purchased from this entity were approximately $2,712,000
in fiscal 2004 and $11,826,000 in fiscal 2005.

         SCP. Headwaters acquired SCP in 2004 and agreed to pay an earn-out to
the sellers if certain earnings targets were exceeded during the 12 months ended
December 31, 2005 (the "earn-out period"). The additional earn-out consideration
will be the product of 5.7 times the amount that earnings before interest,
taxes, depreciation and amortization ("EBITDA") of SCP exceeds $5,500,000 during
the earn-out period. Headwaters currently expects earn-out consideration in the
range of approximately $10,000,000 to $12,500,000 could be paid. Mr. Lents, an
executive officer of Headwaters, owned approximately 30% of SCP prior to the
acquisition and was one of the sellers. Also, a majority of SCP's transportation
needs are provided by a company, two of the principals of which are related to
Mr. Whisnant, an officer of SCP. Costs incurred were approximately $970,000 in
fiscal 2004 and $4,904,000 in fiscal 2005.

         Incentive Agreements with ISG Principals. In January 2003, Headwaters
executed incentive agreements with Messrs. Creamer, Everest and Deju, former
stockholders and officers of ISG, all of whom were officers of either Headwaters
or ISG following the ISG acquisition. The maximum payments would have been
required if there had been a change in control prior to October 2004, or if the
officers remained employed through September 2004 and the average stock price
for any calendar quarter reached $25 per share or more. During fiscal 2004,
Headwaters recorded an expense for $1,500,000 related to this obligation, which
was paid in fiscal 2005. No other payments were made related to these agreements
nor are there any future obligations.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires
Headwaters' officers and directors, and persons who own more than 10% of a
registered class of Headwaters' equity securities, to file reports of ownership
and changes in ownership with the SEC. Officers, directors, and greater than 10%
stockholders are required by SEC regulations to furnish Headwaters with copies
of all Section 16(a) forms they file. Based solely on a review of the copies of
such forms furnished to Headwaters between October 1, 2004 and September 30,
2005, on year-end reports furnished to Headwaters after September 30, 2005, and
on representations that no other reports were required, Headwaters believes that
during the 2005 fiscal year all applicable 16(a) filing requirements were met,
except that Craig R. Hickman filed one Form 4 after the due date for such Form
4.

      PROPOSAL NO. 2 - RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

services rendered for the fiscal years ended September 30, 2004 and September

subsidiaries including the audit of management's assessment and E&Y's assessment
of internal control over financial reporting, plus the costs of quarterly
reviews, SEC filings requiring the consents of Headwaters' independent auditor,
and comfort letters provided to underwriters. Audit-related fees in 2004
consisted primarily of due diligence procedures for a proposed acquisition. Tax
fees consisted primarily of the costs of federal and state income tax filings
for Headwaters and its subsidiaries, a state and local tax planning study,
consultations on the tax treatment of certain acquisition-related transaction
costs and consultations regarding legal entity structures and related potential
asset transfers. All other fees consisted primarily of an annual subscription to
E&Y's online accounting research library. The Audit Committee approved 100% of
the audit fees, the audit-related fees, the tax fees, and all other fees for
2004 and 2005.

services, and non-routine SEC filing reviews, as well as the fees for all large
projects that are expected to cost more than $50,000. The Audit Committee is
informed of and approves all services provided. In addition, it has pre-approved
$100,000 for items that relate to routine accounting consultations related to
items such as new accounting pronouncements, routine SEC filings requiring
consents, and routine tax consultations. Upon performance of such services, the
Audit Committee is informed of and approves the matters to which such
consultations relate. Upon approval by the Audit Committee, the amount is added
back to the pre-approved $100,000.

         In the event that the stockholders do not ratify the appointment of
E&Y, the adverse vote will be considered a directive to the Audit Committee and
the Board to select other auditors for the next fiscal year. A representative of
E&Y is expected to attend the Meeting and will have an opportunity to make a
statement if he or she desires to do so and to respond to appropriate questions.

                             AUDIT COMMITTEE CHARTER

                                  March 9, 2005


Purpose and Composition

         This Charter governs the operations of the Audit Committee. The Audit
Committee shall be comprised of three or more directors as determined by the
Board of Directors and shall meet the qualification requirements of the New York
Stock Exchange listing standards.

         The members of the Audit Committee shall be elected by the Board of
Directors annually and shall serve until their successors are duly elected and
qualified. Unless a Chair is elected by the full Board of Directors, the members
of the Audit Committee may designate a Chair by majority vote of the full Audit
Committee membership.

Statement of Policy

         The Audit Committee shall provide assistance to the Board of Directors
in overseeing the integrity of the Corporation's financial statements,
disclosure controls and procedures, the systems of internal accounting and
financial controls, the Corporation's compliance with legal and regulatory
requirements, the qualifications and independence of the independent auditors,
the performance of the Corporation's internal audit functions and independent
auditors, and the quarterly reviews and annual independent audit of the
Corporation's financial statements.

         The independent auditor for the Corporation is ultimately accountable
to the Audit Committee and the Board of Directors. The Audit Committee and the
Board shall have the ultimate authority and responsibility to select, evaluate
and, where appropriate, replace the independent auditor.

Annual Performance Evaluation

         The Audit Committee shall conduct an annual self-evaluation of the
Audit Committee's performance.

Responsibility and Processes

         The primary responsibility of the Audit Committee is to oversee the
Corporation's financial reporting process on behalf of the Board of Directors
and report the results of its activities to the Board of Directors. It is not
the duty of the Audit Committee to plan or conduct audits, to determine that the
Corporation's financial statements are complete and accurate and are in
accordance with generally accepted accounting principles or to assure compliance
with laws. These are the responsibilities of management, the internal auditor,
and the independent auditor.

         The following shall be the principal recurring processes of the Audit
Committee in carrying out its oversight responsibilities. The processes are set
forth as a guide with the understanding that the Audit Committee may alter or
supplement them as appropriate.

         1. Annually, the Audit Committee shall recommend to the Board of
Directors the selection of the Corporation's independent auditor, subject to
stockholder ratification of the selection, if such ratification is required or
sought.

         2. The Audit Committee shall discuss with the internal auditors and
independent auditor the overall scope and plans for their respective audit
examinations. The Audit Committee shall be responsible for the compensation,
retention, and oversight of the work of the independent auditor (including

                                      B-1


resolution of any disagreements between management and the auditor regarding
financial reporting) for the purpose of preparing or issuing an audit report or
performing other audit, review, or attest services for the Corporation.

         3. The Audit Committee shall ensure that the independent auditor
submits annually a formal written statement delineating all relationships
between the independent auditor and the Corporation. The Audit Committee is
responsible for engaging in a dialogue with the independent auditor with respect
to such disclosed relationships that may impact the objectivity and independence
of the independent auditor and recommending that the Board of Directors take
appropriate action to satisfy itself of the independent auditor's independence.

         4. The Audit Committee shall establish policies and procedures for the
engagement of the independent auditor to provide non-audit services, and
consider whether the independent auditor's performance of non-audit services is
compatible with the independent auditor's independence.

         5. The Audit Committee shall at least annually obtain and review a
report by the independent auditor describing: the firm's internal
quality-control procedures; any material issues raised by the most recent
internal quality-control review, or peer review, of the firm, or by any inquiry
or investigation by governmental or professional authorities, within the
preceding five years, respecting one or more independent audits carried out by
the firm, and any steps taken to deal with any such issues.

         6. The Audit Committee should review the auditor's qualifications,
performance, and independence. This evaluation should include the review and
evaluation of the lead partner of the independent auditor. In making its
evaluation, the Audit Committee should take into account the opinions of
management and the Corporation's internal auditors. In addition to assuring the
regular rotation of the lead audit partner as required by law, the Audit
Committee should further consider whether, in order to assure continuing auditor
independence, there should be regular rotation of the audit firm itself. The
Audit Committee should present its conclusions with respect to the independent
auditor to the Board of Directors of the Corporation.

         7. The Audit Committee shall discuss with management, the internal
auditors, and the independent auditor the adequacy and effectiveness of the
Corporation's internal controls, accounting and financial records, and the
system for monitoring and managing business risk and legal compliance. Further,
the Audit Committee shall meet separately with the independent auditor, with and
without management present, to discuss the results of their examinations.

         8. The Audit Committee shall review and discuss with management, the
internal auditors, and the independent auditor the Corporation's interim
financial results to be included in the Corporation's quarterly reports filed
with the Securities and Exchange Commission, and the matters required to be
discussed by Statement on Auditing Standards No. 61 (Communications with Audit
Committees), as it may be modified or supplemented.

         9. The Audit Committee shall review with management, the internal
auditors, and the independent auditor the financial statements, including
reviewing the Corporation's specific disclosures under "Management's Discussion
and Analysis of Financial Condition and Results of Operations," to be included
in the Corporation's Annual Report on Form 10-K (or the annual report to
shareholders if distributed prior to the filing of Form 10-K), as well as the
auditor's judgment about the quality, not just acceptability, of the
Corporation's accounting principles as applied in its financial reporting. The
review shall also include a discussion of the reasonableness of judgments and
estimates made in the preparation of the financial statements that may be viewed
as critical, as well as the clarity of financial statement disclosures. In
addition, the Audit Committee shall discuss the results of the annual audit and
any other matters required to be communicated to the Audit Committee by the
independent auditor under generally accepted auditing standards, including the
matters required to be discussed by Statement on Auditing Standards No. 61
(Communications with Audit Committees), as it may be modified or supplemented.

         10. Based on its review and discussions of items 3 and 8, the Audit
Committee shall recommend to the Board of Directors whether the financial
statements, including the Corporation's specific disclosures under "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
should be included in the Annual Report on Form 10-K (or the annual report to
shareholders if distributed prior to the filing of Form 10-K).

                                      B-2


         11. As a whole, or through the Chair, the Audit Committee shall review
the impact on the financial statements of significant events, transactions, or
changes in accounting principles or estimates which potentially affect the
quality of the financial reporting with management and the independent auditor
prior to the filing of the Corporation's Reports on Form 10-Q or 10-K, or as
soon as practicable if the communications cannot be made prior to its filing.

         12. Management and the independent auditor shall discuss with the Audit
Committee significant changes to the Corporation's auditing and accounting
principles, policies, controls, procedures and practices proposed or
contemplated by the independent auditor or management.

         13. The Audit Committee shall review and reassess this Charter annually
and recommend any appropriate changes to the Board of Directors.

         14. The Audit Committee shall discuss the Corporation's earnings press
releases, as well as financial information and earnings guidance provided to
analysts and ratings agencies.

         15. The Audit Committee shall discuss guidelines and policies with
respect to risk assessment and risk management, including the Corporation's
major financial risk exposures and the steps management has taken to monitor and
control such exposures.

         16. The Audit Committee shall meet separately, periodically, with
management, with internal auditors (or other personnel responsible for the
internal audit function) and with independent auditors.

         17. The Audit Committee shall set clear hiring policies for employees
or former employees of the independent auditors.

         18. The Audit Committee shall establish procedures for the receipt,
retention, and treatment of complaints received by the Corporation regarding
accounting, internal accounting controls, or auditing matters. The Audit
Committee shall also establish procedures for the confidential, anonymous
submission by employees of the Corporation of concerns regarding questionable
accounting or auditing matters.

          19. The Corporation shall provide for appropriate funding, as
determined by the Audit Committee, for payment of compensation to the
independent auditor, compensation to any advisors employed by the Audit
Committee, and ordinary administrative expenses of the Audit Committee that are
necessary or appropriate in carrying out its duties.

         20. The Audit Committee shall review with the independent auditor any
audit problems or difficulties, and management's response. The scope of review
should include any restrictions on the scope of the independent auditor's
activities or access to requested information, and any significant disagreement
that is brought to its attention, after inquiry, among management and the
independent auditor or internal auditor in connection with the preparation of
the Corporation's financial statements. The Audit Committee should encourage
both management and the independent auditor to communicate openly with the Audit
Committee regarding such disagreements. In addition, the Audit Committee shall
review with management and the independent auditor any pending or threatened
action by regulators or government agencies and any employee complaints or
published reports that raise material issues regarding the Corporation's
financial statements or accounting policies. The Audit Committee may request any
officer or employee of the Corporation or the Corporation's outside counsel or
independent auditor to attend a meeting of the Audit Committee or to meet with
any members of, or consultants to, the Audit Committee. The Audit Committee
shall also have the resources and authority appropriate to discharge its
responsibilities, including the authority to engage outside auditors for special
audits, reviews and other procedures and to retain special counsel and other
experts or consultants.

         1. The Audit Committee shall prepare or cause the preparation of the
report required by the rules of the Securities and Exchange Commission for
inclusion in the Corporation's annual proxy statement.

                                      B-3

Audit Committee Charter to the full Board of Directors for approval.

         3. The Audit Committee shall maintain minutes of its meetings and
regularly report its activities to the Board of Directors.
