                        2000 EMPLOYEE STOCK PURCHASE PLAN

SECTION 1         Purpose Of The Plan.

         The Plan was adopted by the Board on May 25, 2000, effective as of June
1, 2000. The purpose of the Plan is to provide Eligible Employees with an
opportunity to increase their proprietary interest in the success of the Company
by purchasing Stock in the Company on favorable terms and to pay for such
purchases through payroll deductions. The Plan is intended to qualify under
section 423 of the Code.

SECTION 2         Definitions.

         (a) "Board" means the Board of Directors of the Company, as constituted
from time to time.

         (b) "Code" means the Internal Revenue Code of 1986, as amended.

         (c) "Committee" means a committee of the Board, as described in Section
3.

         (d) "Company" means Headwaters Incorporated, a Delaware Corporation
(formerly Covol Technologies, Inc.).

         (e) "Compensation" means (i) the total compensation paid in cash to a
Participant by a Participating Company, including salaries, wages, bonuses,
incentive compensation, commissions, overtime pay and shift premiums, plus (ii)
any pre-tax contributions made by the Participant under section 401(k) or 125 of
the Code. "Compensation" shall exclude all non-cash items, moving or relocation
allowances, cost-of-living equalization payments, car allowances, tuition
reimbursements, imputed income attributable to cars or life insurance, severance
pay, fringe benefits, contributions or benefits received under employee benefit
plans, income attributable to the exercise of stock options, and similar items.
The Committee shall determine whether a particular item is included in
Compensation.

         (f) "Corporate Reorganization" means:

                  (i) The consummation of a merger or consolidation of the
         Company with or into another entity, or any other corporate
         reorganization; or

                  (ii) The sale, transfer or other disposition of all or
         substantially all of the Company's assets or the complete liquidation
         or dissolution of the Company.

         (g) "Eligible Employee" means any Employee of a Participating Company
who meets both of the following requirements:

                                      -1-
<PAGE>

                  (i) His or her customary employment is for more than five
         months per calendar year and for more than 20 hours per week; and

                  (ii) He or she has been an Employee of a Participating Company
         for not less than three consecutive months.

         The foregoing notwithstanding, Employees employed on the Plan's
effective date do not have to satisfy the service requirements specified above.

         The foregoing notwithstanding, an individual shall not be considered an
Eligible Employee if his or her participation in the Plan is prohibited by the
law of any country which has jurisdiction over him or her or if he or she is
subject to a collective bargaining agreement that does not provide for
participation in the Plan.

         (h) "Employee" means an individual paid from W-2 Payroll of the Company
or a Subsidiary. If, during any period, the Company (or Subsidiary, as
applicable) has not treated an individual as an Employee and, for that reason,
has not paid such individual in a manner which results in the issuance of a Form
W-2 and withheld taxes with respect to him or her, then that individual shall
not be eligible to participate in the Plan for that period, even if any person,
court of law or government agency determines, retroactively, that such
individual is or was a common-law employee during all or any portion of that
period. "W-2 Payroll" means whatever mechanism or procedure that the Company or
a Subsidiary uses to pay any individual which results in the issuance of Form
W-2 to the individual. "W-2 Payroll" does not include any mechanism or procedure
which results in the issuance of any form other than a Form W-2 to an
individual, including, but not limited to, any Form 1099 which may be issued to
an independent contractor, an agency employee or a consultant. Whether a
mechanism or procedure qualifies as a "W-2 Payroll" shall be determined in the
absolute discretion of the Company (or Subsidiary, as applicable), and the
Company's or Subsidiary's determination shall be conclusive and binding on all
persons.

         (i) "Exchange Act" means the Securities Exchange Act of 1934, as
amended.

         (j) "Fair Market Value" with respect to a Share, shall mean the market
price of one Share of Stock, determined by the Committee as follows:

                  (i) If the Stock was traded over-the-counter on the date in
         question but was not traded on The Nasdaq Stock Market, then the Fair
         Market Value shall be equal to the last transaction price quoted for
         such date by the OTC Bulletin Board or, if not so quoted, shall be
         equal to the mean between the last reported representative bid and
         asked prices quoted for such date by the principal automated
         inter-dealer quotation system on which the Stock is quoted or, if the
         Stock is not quoted on any such system, by the "Pink Sheets" published
         by the National Quotation Bureau, Inc.;

                  (ii) If the Stock was traded on The Nasdaq Stock Market, then
         the Fair Market Value shall be equal to the last reported sale price
         quoted for such date by The Nasdaq Stock Market;

                                      -2-
<PAGE>

                  (iii) If the Stock was traded on a United States stock
         exchange on the date in question, then the Fair Market Value shall be
         equal to the closing price reported for such date by the applicable
         composite-transactions report; and

                  (iv) If none of the foregoing provisions is applicable, then
         the Fair Market Value shall be determined by the Committee in good
         faith on such basis as it deems appropriate.

         In all cases, the determination of Fair Market Value by the Committee
shall be conclusive and binding on all persons.

         (k) "Offering Period" means a calendar quarter period with respect to
which the right to purchase Stock may be granted under the Plan, as determined
pursuant to Section 4(a).

         (l) "Participant" means an Eligible Employee who elects to participate
in the Plan, as provided in Section 4(b).

         (m) "Participating Company" means (i) the Company and (ii) each present
or future Subsidiary designated by the Committee as a Participating Company.

         (n) "Plan" means this Headwaters Incorporated 2000 Employee Stock
Purchase Plan, as it may be amended from time to time.

         (o) "Plan Account" means the account established for each Participant
pursuant to Section 8(a).

         (p) "Purchase Price" means the price at which Participants may purchase
Stock under the Plan, as determined pursuant to Section 8(b).

         (q) "Stock" means the Common Stock of the Company.

         (r) "Subsidiary" means any corporation (other than the Company) in an
unbroken chain of corporations beginning with the Company, if each of the
corporations other than the last corporation in the unbroken chain owns stock
possessing 50% or more of the total combined voting power of all classes of
stock in one of the other corporations in such chain.

SECTION 3         Administration Of The Plan.

         (a) Committee Composition. The Plan shall be administered by the
Committee. The Committee shall consist exclusively of one or more directors of
the Company, who shall be appointed by the Board.

         (b) Committee Responsibilities. The Committee shall interpret the Plan
and make all other policy decisions relating to the operation of the Plan. The
Committee may adopt such rules, guidelines and forms as it deems appropriate to
implement the Plan. The Committee's determinations under the Plan shall be final
and binding on all persons.

                                      -3-

SECTION 4         Enrollment And Participation.

         (a) Offering Periods. While the Plan is in effect, one Offering Period
shall commence in each calendar quarter. The Offering Periods shall consist of
the quarterly periods commencing on the first day of each calendar quarter and
ending on the last day of each calendar quarter.

         (b) Enrollment. Any individual who, on the day preceding the first day
of an Offering Period, qualifies as an Eligible Employee may elect to become a
Participant in the Plan for such Offering Period by executing the enrollment
form prescribed for this purpose by the Committee. The enrollment form shall be
filed with the Company at the prescribed location not later than 15 days prior
to the commencement of such Offering Period.

         (c) Duration of Participation. Once enrolled in the Plan, a Participant
shall continue to participate in the Plan until he or she ceases to be an
Eligible Employee, withdraws from the Plan under Section 6(a) or reaches the end
of the Offering Period in which his or her employee contributions were
discontinued under Section 5(d) or 9(b). A Participant who discontinued employee
contributions under Section 5(d) or withdrew from the Plan under Section 6(a)
may again become a Participant, if he or she then is an Eligible Employee, by
following the procedure described in Subsection (b) above. A Participant whose
employee contributions were discontinued automatically under Section 9(b) shall
automatically resume participation at the beginning of the first Offering Period
beginning in the next calendar year, if he or she then is an Eligible Employee.

SECTION 5         Employee Contributions.

         (a) Frequency of Payroll Deductions. A Participant may purchase shares
of Stock under the Plan solely by means of payroll deductions. Payroll
deductions, as designated by the Participant pursuant to Subsection (b) below,
shall occur on each payday during participation in the Plan.

         (b) Amount of Payroll Deductions. An Eligible Employee shall designate
on the enrollment form the portion of his or her Compensation that he or she
elects to have withheld for the purchase of Stock. Such portion shall be a whole
percentage of the Eligible Employee's Compensation, but not less than 1% and not
more than 10%.

         (c) Changing Withholding Rate. A Participant may change the rate of
withholding once every six months. If a Participant wishes to change the rate of
payroll withholding, he or she may do so by filing the prescribed form with the
Company at the time specified. The new withholding rate shall be effective as of
the first day of the January or July next following the date such form has been
timely received by the Company. The new withholding rate shall be a whole
percentage of the Eligible Employee's Compensation, but not less than 1% and not
more than 10%.

         (d) Discontinuing Payroll Deductions. If a Participant wishes to
discontinue employee contributions entirely, he or she may do so by filing the
prescribed form with the Company at the prescribed location at any time. Payroll
withholding shall cease as soon as reasonably practicable after such form has
been received by the Company. (In addition, employee contributions may be
discontinued automatically pursuant to Section 9(b).) A Participant who has
discontinued

                                      -4-
<PAGE>

employee contributions may resume such contributions by filing a new enrollment
form with the Company at the prescribed location. Payroll withholding shall
resume effective as of the first day of the January or July next following the
date such form has been timely received by the Company.

SECTION 6         Withdrawal From The Plan.

         (a) Withdrawal. A Participant may elect to withdraw from the Plan by
filing the prescribed form with the Company at the prescribed location at any
time before the last day of an Offering Period. As soon as reasonably
practicable thereafter, payroll deductions shall cease and the entire amount
credited to the Participant's Plan Account shall be refunded to him or her in
cash, without interest. No partial withdrawals shall be permitted.

         (b) Re-enrollment After Withdrawal. A former Participant who has
withdrawn from the Plan shall not be a Participant until he or she re-enrolls in
the Plan under Section 4(c). Re-enrollment shall be effective as of the first
day of the January or July next following the date the enrollment form has been
timely received by the Company.

SECTION 7         Change In Employment Status.

         (a) Termination of Employment. Termination of employment as an Eligible
Employee for any reason, including death, shall be treated as an automatic
withdrawal from the Plan under Section 6(a). (A transfer from one Participating
Company to another shall not be treated as a termination of employment.)

         (b) Leave of Absence. For purposes of the Plan, employment shall not be
deemed to terminate when the Participant goes on a military leave, a sick leave
or another bona fide leave of absence, if the leave was approved by the Company
in writing. Employment, however, shall be deemed to terminate 90 days after the
Participant goes on a leave, unless a contract or statute guarantees his or her
right to return to work. Employment shall be deemed to terminate in any event
when the approved leave ends, unless the Participant immediately returns to
work.

         (c) Death. In the event of the Participant's death, the amount credited
to his or her Plan Account shall be paid to a beneficiary designated by him or
her for this purpose on the prescribed form or, if none, to the Participant's
estate. Such form shall be valid only if it was filed with the Company at the
prescribed location before the Participant's death.

SECTION 8         Plan Accounts And Purchase Of Shares.

         (a) Plan Accounts. The Company shall maintain a Plan Account on its
books in the name of each Participant. Whenever an amount is deducted from the
Participant's Compensation under the Plan, such amount shall be credited to the
Participant's Plan Account. Amounts credited to Plan Accounts shall not be trust
funds and may be commingled with the Company's general assets and applied to
general corporate purposes. No interest shall be credited to Plan Accounts.

         (b) Purchase Price. The Purchase Price for each share of Stock
purchased at the close of an Offering Period shall be the lower of :

                                      -5-
<PAGE>

                  (i) 85% of the Fair Market Value of such share on the last
         trading day in such Offering Period; or

                  (ii) 85% of the Fair Market Value of such share on the last
         trading day before the commencement of such Offering Period.

         (c) Number of Shares Purchased. As of the last day of each Offering
Period, each Participant shall be deemed to have elected to purchase the number
of shares of Stock calculated in accordance with this Subsection (c), unless the
Participant has previously elected to withdraw from the Plan in accordance with
Section 6(a). The amount then in the Participant's Plan Account shall be divided
by the Purchase Price, and the number of shares that results shall be purchased
from the Company with the funds in the Participant's Plan Account. The foregoing
notwithstanding, no Participant shall purchase more than the amounts of Stock
set forth in Sections 9(b) and 14(a). The Committee may determine with respect
to all Participants that any fractional share, as calculated under this
Subsection (c), shall be (i) rounded down to the next lower whole share or (ii)
credited as a fractional share.

         (d) Available Shares Insufficient. In the event that the aggregate
number of shares that all Participants elect to purchase during an Offering
Period exceeds the maximum number of shares remaining available for issuance
under Section 14(a), then the number of shares to which each Participant is
entitled shall be determined by multiplying the number of shares available for
issuance by a fraction, the numerator of which is the number of shares that such
Participant has elected to purchase and the denominator of which is the number
of shares that all Participants have elected to purchase.

         (e) Issuance of Stock. Certificates representing the shares of Stock
purchased by a Participant under the Plan shall be issued to him or her as soon
as reasonably practicable after the close of the applicable Offering Period,
except that the Committee may determine that such shares shall be held for each
Participant's benefit by a broker designated by the Committee (unless the
Participant has elected that certificates be issued to him or her). Shares may
be registered in the name of the Participant or jointly in the name of the
Participant and his or her spouse as joint tenants with right of survivorship or
as community property.

         (f) Unused Cash Balances. Any amount remaining in the Participant's
Plan Account that represents the Purchase Price for a fractional share shall be
carried over in the Participant's Plan Account to the next Offering Period. Any
amount remaining in the Participant's Plan Account that represents the Purchase
Price for whole shares that could not be purchased by reason of Subsection (c)
above, Section 9(b) or Section 14(a) shall be refunded to the Participant in
cash, without interest.

         (g) Stockholder Approval. The Company's stockholders must approve the
adoption of the Plan within twelve months after the Plan is adopted by the Board
of Directors of the Company.

SECTION 9         Limitations On Stock Ownership.

         (a) Five Percent Limit. Any other provision of the Plan
notwithstanding, no Participant shall be granted a right to purchase Stock under
the Plan if such Participant, immediately after

                                      -6-
<PAGE>

his or her election to purchase such Stock, would own stock possessing more than
5% of the total combined voting power or value of all classes of stock of the
Company or Subsidiary of the Company. For purposes of this Subsection (a), the
following rules shall apply:

                  (i) Ownership of stock shall be determined after applying the
         attribution rules of section 424(d) of the Code; and

                  (ii) Each Participant shall be deemed to own any stock that he
         or she has a right or option to purchase under this or any other plan.

         (b) Dollar Limit. Any other provision of the Plan notwithstanding, no
Participant shall purchase Stock with a Fair Market Value in excess of the
following limit:

                  (i) In the case of Stock purchased during an Offering Period
         that commenced in the current calendar year, the limit shall be equal
         to (A) $25,000 minus (B) the Fair Market Value of the Stock that the
         Participant previously purchased in the current calendar year (under
         this Plan and all other employee stock purchase plans of the Company or
         Subsidiary of the Company).

                  (ii) Any other provision of the Plan notwithstanding, no
         Participant shall purchase Stock with a Fair Market Value in excess of
         $25,000 per calendar year (under this Plan and all other employee stock
         purchase plans of the Company or any Subsidiary of the Company).

         For purposes of this Subsection (b), the Fair Market Value of Stock
shall be determined in each case as of the beginning of the Offering Period in
which such Stock is purchased. Employee stock purchase plans not described in
section 423 of the Code shall be disregarded. If a Participant is precluded by
this Subsection (b) from purchasing additional Stock under the Plan, then his or
her employee contributions shall automatically be discontinued and shall resume
at the beginning of the earliest Offering Period ending in the next calendar
year (if he or she then is an Eligible Employee).

SECTION 10        Rights Not Transferable.

         The rights of any Participant under the Plan, or any Participant's
interest in any Stock or moneys to which he or she may be entitled under the
Plan, shall not be transferable by voluntary or involuntary assignment or by
operation of law, or in any other manner other than by beneficiary designation
or the laws of descent and distribution. If a Participant in any manner attempts
to transfer, assign or otherwise encumber his or her rights or interest under
the Plan, other than by beneficiary designation or the laws of descent and
distribution, then such act shall be treated as an election by the Participant
to withdraw from the Plan under Section 6(a).

SECTION 11        No Rights As An Employee

         Nothing in the Plan or in any right granted under the Plan shall confer
upon the Participant any right to continue in the employ of a Participating
Company for any period of specific duration or interfere with or otherwise
restrict in any way the rights of the Participating

                                      -7-
<PAGE>

Companies or of the Participant, which rights are hereby expressly reserved by
each, to terminate his or her employment at any time and for any reason, with or
without cause.

SECTION 12        No Rights As A Stockholder.

         A Participant shall have no rights as a stockholder with respect to any
shares of Stock that he or she may have a right to purchase under the Plan until
such shares have been purchased on the last day of the applicable Offering
Period.

SECTION 13        Securities Law Requirements.

         Shares of Stock shall not be issued under the Plan unless the issuance
and delivery of such shares comply with (or are exempt from) all applicable
requirements of law, including (without limitation) the Securities Act of 1933,
as amended, the rules and regulations promulgated thereunder, state securities
laws and regulations, and the regulations of any stock exchange or other
securities market on which the Company's securities may then be traded.

SECTION 14        Stock Offered Under The Plan.

         (a) Authorized Shares. The aggregate number of shares of Stock
available for purchase under the Plan shall be 500,000, subject to adjustment
pursuant to this Section 14. The Company may either use authorized but unissued
stock, treasury stock, or stock purchased on the open market in order to fulfill
its obligations under the Plan.

         (b) Antidilution Adjustments. The aggregate number of shares of Stock
offered under the Plan and the price of shares that any Participant has elected
to purchase shall be adjusted proportionately by the Committee for any increase
or decrease in the number of outstanding shares of Stock resulting from a
subdivision or consolidation of shares or the payment of a stock dividend, any
other increase or decrease in such shares effected without receipt or payment of
consideration by the Company, the distribution of the shares of a Subsidiary to
the Company's stockholders or a similar event.

         (c) Reorganizations. Any other provision of the Plan notwithstanding,
immediately prior to the effective time of a Corporate Reorganization, the
Offering Period then in progress shall terminate and shares shall be purchased
pursuant to Section 8, unless the Plan is assumed by the surviving corporation
or its parent corporation pursuant to the plan of merger or consolidation. The
Plan shall in no event be construed to restrict in any way the Company's right
to undertake a dissolution, liquidation, merger, consolidation or other
