                                    AGREEMENT

         NOW, THEREFORE, in consideration of the foregoing and for other good
and valuable consideration the receipt and sufficiency of which are hereby
acknowledged, the parties, intending to be legally bound, hereby agree as
follows:

                                    ARTICLE 1
                                   DEFINITIONS

         1.1. "Coal Technology" means Covol's proprietary method of reclaiming
and utilizing discarded and newly formed coal fines and other by-products of
coal mining to produce a solid proprietary product in the form of briquettes,
extrusions, pellets or otherwise.

         The definition of "Coal Technology" also includes Covol's proprietary
inventions (patented and unpatented), trade secrets, know-how, working
prototypes, manufacturing information, improvements and other intellectual
property relating to Covol's proprietary method of reclaiming discarded coal
fines and other by-products of coal mining to produce Covol's solid proprietary
product. Some of Covol's inventions relating to the "Coal Technology" (as well
as other technologies which are not the subject of this Agreement) are
disclosed, described and claimed in United States Patent No. 5,453,103, which
issued on the 26th day of September, 1995 (the "`103 Patent"). Some of Covol's
inventions relating to the "Coal Technology" (as well as other technologies
which are not the subject of this Agreement) are disclosed, described and
claimed in the United States Patent No. 5,599,361 issued on the 4th day of
February, 1997 (the "361 Patent"). In Article III of the License Agreement,
CoBon received an exclusive license with respect to "Coal Technology."

         The definition of "Coal Technology" also includes the binding
technology and patented process for manufacturing a solid synthetic fuel that
qualifies and is eligible for Internal Revenue Code Section 29 tax credits. When
used at a qualified facility in conjunction with Covol's patented manufacturing
process, the binding technology produces a Qualified Fuel from coal fines in the
context of a full scale or less demanding manufacturing application. Consistent
with the requirements of Internal Revenue Code Section 29, the "Coal Technology"
employs a unique substrate to chemically change and bond the coal fines, thereby
creating a Qualified Fuel. The detectable bonding between the coal fines is the
result of the binder's ability to create an actual chemical change to the coal
fines and is more than a simple physical mixture of polymer, coal fines and
other additives.

                                       2
<PAGE>

         The definition of "Coal Technology" does not cover any other technology
or application of technology, including but not limited to Covol's proprietary
"Coke Breeze Technology," "Revert Technology" and "Iron Recovery Technology".

         1.2 "Binder" means Covol's unique substrates that chemically change and
bond coal fines, and which have been patented by Covol.

         1.3 "Qualified Fuels" means solid synthetic fuel produced at the
Facility that qualifies and is eligible for Internal Revenue Code Section 29 tax
credits.

                                    ARTICLE 2

Central City, Pennsylvania (the "Facility"). This Sublicense shall also be
available for use by Central City in connection with its development of
additional sites, subject to the written approval of CoBon, which approval will
not be unreasonably withheld. Central City shall not use any technology other
than the Coal Technology for the production of Qualified Fuel at the Facility,
except as provided in Section 5.1.

         2.2. Retained Ownership. Covol shall retain all right, title, interest
and ownership in and to the Coal Technology, including all inventions described
and claimed in the `103 Patent and the `361 Patent, all present and future

license to use the trademarks and trade names used by Covol in connection with
the Coal Technology. The authorized use by Central City of any of the trademarks
sublicensed hereby shall be in accordance with Covol's written standards which
shall govern the manner of use and the nature and quality of the products in
connection with which they may be used. CoBon will furnish to Central City a
copy of any such applicable standards upon receipt thereof by CoBon.

         2.5. Compliance Certification. At Central City's request, CoBon shall
use its best efforts to coordinate and schedule Covol (at least annually) to

City's proper use of the Coal Technology and Binder for Section 29 tax credit
qualification. Pursuant to the audit fee schedule, attached as Exhibit B hereto,
Central City shall reimburse Covol for its reasonable costs in performing the
audits. Central City shall also reimburse CoBon for its reasonable costs and for
the reasonable value of its time in performing its obligations, if any, under
this Section 2.5.

                                    ARTICLE 3
                         REPRESENTATIONS AND WARRANTIES

         3.1. Covol Representations and Warranties. Covol hereby represents and

                                    ARTICLE 4
                           ROYALTIES, FEES AND PAYMENT

         4.1. Royalties, Fees and Payments.

                  Central City shall pay, as consideration for its use of the
Coal Technology, an Initial Royalty Fee (as hereinafter defined) and an Earned
Royalty Fee (as hereinafter defined).

         4.2. Initial Royalty Fee.

                  A. Initial Royalty Fee. The term "Initial Royalty Fee" shall
mean a sum equal to the product of (a) $**** per ton of Qualified Fuels,
multiplied by (b) the first 650,000 tons of Qualified Fuels produced at the
Facility; provided, however, that the Initial Royalty Fee shall not exceed
$****.

                  B. Payment of Initial Royalty Fee. The Initial Royalty Fee
shall be payable as follows:

                           1. Covol Initial Royalty Fee. Central City shall pay
to CoBon, as CoBon's payment to Covol pursuant to the License Agreement, a sum
equal to the product of (A) $**** per ton of Qualified Fuels, multiplied by (B)
the tons of Qualified Fuels actually produced at the Facility from 12:00 a.m. on
December 14, 1999, through the earlier to occur of (i) 11:59 p.m. of the last
day of the month in which an IRS Ruling (as defined below) is received by or on
behalf of Central City (the "IRS Ruling Month"), or (ii) the date on which the
Facility produces the 650,000th ton of Qualified Fuels, assuming that December
14, 1999 was the date that the Facility commenced the production of Qualified
Fuels (the "Maximum Tonnage Date"). Notwithstanding the foregoing provisions of
this paragraph, to the extent that Central City has paid any of the fees
described in the immediately foregoing sentence with respect to Qualified Fuels
produced at the Facility from December 14, 1999 until the date hereof, Central
City shall not be obligated to pay such fees to CoBon. The term "IRS Ruling"
shall mean a private letter ruling from the IRS with respect to the availability
of tax credits under Section 29 of the Internal Revenue Code (the "Code") for
the Qualified Fuel produced by the Facility (the "Tax Credits").

                           2. CoBon Initial Royalty Fee. Central City shall pay
to CoBon a sum equal to the product of (A) $**** per ton of Qualified Fuels,
multiplied by (B) the tons of Qualified Fuels actually produced at the Facility
from 12:00 a.m. on December 14, 1999 through the earlier to occur of (i) 11:59
p.m. of the last day of the IRS Ruling Month, or (ii) the Maximum Tonnage Date.
Payment of the CoBon Initial Royalty Fee shall accrue and be deferred until an
IRS Ruling. CoBon's Initial Royalty Fee shall be payable as follows:

                                    (a) Favorable Ruling. If the IRS Ruling
received by Central City is favorable (a "Favorable Ruling"), as determined by
Central City in its sole discretion, then, within thirty (30) days after the end
of the IRS Ruling Month:

                                       8
<PAGE>

                                             (1) if the end of the IRS Ruling
Month is subsequent to the Maximum Tonnage Date, Central City shall pay to CoBon
the sum of $**** (which is the product of $**** per ton of Qualified Fuels
multiplied by 650,000 tons of Qualified Fuels); or

                                             (2) if the end of the IRS Ruling
Month is prior to the Maximum Tonnage Date, Central City shall pay CoBon a sum
equal to the product of (A) $**** per ton of Qualified Fuels, multiplied by (B)
the tons of Qualified Fuels actually produced at the Facility from 12:00 a.m. on
December 14, 1999 through 11:59 p.m. of the last day of the IRS Ruling Month.

                                    (b) Unfavorable Ruling; Cessation of
Production. If the IRS Ruling received by Central City is unfavorable or, for
any reason, other than the failure of Central City to diligently seek a ruling,
no IRS Ruling is received on or prior to June 7, 2002, as determined by Central
City in its sole discretion (collectively, an "Unfavorable Ruling"), and the
Facility ceases production of Qualified Fuel as a result of such Unfavorable
Ruling, then Central City shall not be required to pay to CoBon any of the
Initial Royalty Fee as required pursuant to Section 4.2(B)(1) and Section
4.2(B)(2) and any such payments made pursuant to those referenced sections shall
immediately cease. However, if notwithstanding the Unfavorable Ruling, Central
City, in its sole discretion, seeks to obtain the benefit of the Tax Credits, if
any, acquired prior to such cessation of production, Central City shall pay
CoBon, within thirty (30) days of the time that Central City reasonably
determines that such Tax Credits are not subject to challenge or reversal, a sum
equal to product of (A) $**** per ton of Qualified Fuels, multiplied by (B) the
tons of Qualified Fuels actually produced at the Facility from 12:00 a.m. on
December 14, 1999 through the earlier to occur of (i) the Maximum Tonnage Date,
or (ii) 11:59 p.m. of the last day of the IRS Ruling Month, for which Tax
Credits were allowed.

                                    (c) Unfavorable Ruling; Notice; Agreement to
Negotiate. If an Unfavorable Ruling is received or deemed received then Central
City shall promptly give notice thereof to CoBon and thereafter Central City and
CoBon may enter into negotiations to determine the terms and conditions on which
Central City may continue the use of the Coal Technology without triggering the
provisions of Section 4.2(B)(2)(d); provided, however, that neither Central City
nor CoBon shall be obligated to modify the terms and conditions on which Central
City may continue the use of the Coal Technology.

                                    (d) Unfavorable Ruling; Continuation of
Production. If an Unfavorable Ruling is received or deemed received and the
Facility does not cease production of Qualified Fuel, then a lump sum payment
shall be made in accordance with either Section 4.2(B)(2)(a)(1) or Section
4.2(B)(2)(a)(2), as applicable.

                  C. Payment of Initial Royalty Fees Prior to Maximum Tonnage
Date but after IRS Ruling. If either an Unfavorable Ruling or a Favorable Ruling
is received prior to the Maximum Tonnage Date and Central City continues
production of Qualified Fuel, then Central City shall pay CoBon, in accordance
with the terms hereof and subject to Section 4.2(A), $**** per ton of Qualified
Fuel actually produced at the Facility from 12:00 a.m. on the first day
following the end of the IRS Ruling Month through the earlier to occur of (i)
the Maximum Tonnage Date, or (ii) the date upon which Central City terminates
production at the Facility, such payments to be made in arrears within fifteen
(15) days following the end of each calendar month, based on production during
such previous calendar month.

         4.3. Earned Royalty Fee.

                  A. Earned Royalty Fee. The earned royalty fee (the "Earned
Royalty Fee") shall be in an amount equal to the sum of (x) the product of (1)
$**** per ton of Qualified Fuel, multiplied by (2) the tons of Qualified Fuels
produced at the Facility in excess of 250,000 tons, up to 650,000 tons, during
any calendar year, plus (y) the product of (1) $**** per ton of Qualified Fuel
multiplied by (2) the tons of Qualified Fuel produced at the Facility in excess
of 650,000 tons, during any calendar year. The Earned Royalty Fee shall be
payable as provided in this Agreement notwithstanding any use by Central City of
an alternative binder under Section 5.1. Central City and CoBon agree that
production of Qualified Fuels commenced on December 14, 1999. Payment of the
Earned Royalty Fee shall be calculated on an annual basis, notwithstanding the
provisions of Section 4.3(B)(1) and Section 4.4 below which require payment

                                       9
<PAGE>

based on the production of Qualified Fuels during a calendar quarter, and
therefore Central City and CoBon shall make adjustments to the calendar quarter
payments to ensure that the amounts paid to CoBon reflect payment of the Earned
Royalty Fee on an annual basis.

                  B. Payment of Earned Royalty Fees. Until an IRS Ruling is
received, all the Earned Royalty Fees shall accrue but shall not be payable by
Central City (such accrued Earned Royalty Fees, the "Accrued Earned Royalty
Fees"). After an IRS Ruling is received, then:

                           1. Favorable Ruling. If a Favorable Ruling is
received, then Central City shall be obligated to pay to CoBon (a) all Accrued
Earned Royalty Fees, such fees to be paid within ten (10) days of the date of
the Favorable Ruling; and (b) all Earned Royalty Fees based on the production of
Qualified Fuels after the IRS Ruling, such fees to be made in arrears within
fifteen (15) days following the end of each such calendar quarter, based on
production during such previous calendar quarter, until this Agreement is
terminated pursuant to Article 6.

                           2. Unfavorable Ruling; Cessation of Production. If an
Unfavorable Ruling is received and the Facility ceases production of Qualified
Fuel as a result of such Unfavorable Ruling, and

                                    (a) if Central City does not obtain the
benefit of any Tax Credits, Central City shall not make any payments of any
nature to CoBon, including the Accrued Earned Royalty Fee; or

                                    (b) if, notwithstanding the Unfavorable
Ruling, Central City, in its sole discretion, does seek to obtain the benefit of
the Tax Credits, if any, acquired prior to such cessation of production, within
ten (10) days of the time that Central City reasonably determines that such Tax
Credits are not subject to challenge or reversal, Central City shall pay CoBon,
the Accrued Earned Royalty Fees for which Tax Credits were allowed, or in the
event of a Final Determination (as defined below), a sum equal to (a) the

                                       10
<PAGE>

product of (i) the Accrued Earned Royalty Fees that would have been payable to
CoBon if a Favorable Ruling had been received, multiplied by (ii) a fraction,
the numerator of which is the amount of Tax Credits allowed to Central City
pursuant to a Final Determination with respect to the Tax Credits claimed by
Central City, minus any interest and penalties (including substantial
understatement penalties and any penalties for underpayment of estimated taxes
to the extent attributable to Tax Credits claimed by Central City), and the
denominator of which is the amount of Tax Credits claimed by Central City, (b)
plus interest accrued at 9% per annum commencing on the date that the Accrued
Earned Royalty Fees described above were due.

                           3. Unfavorable Ruling; Continuation of Production. If
a Unfavorable Ruling is received or deemed received and the Facility does not
cease production of Qualified Fuel, then a lump sum payment shall be made in
accordance with Section 4.3(B)(1).

         4.4      Tax Event

                  A. Definitions. For purposes of this Section 4.4 the following
terms shall have the following meanings:

                           1. "Tax Event" means: (i) the issuance of any
information document request related to Tax Credits or any other reasonable
indication of an intention by the IRS or any related governmental authority to
examine or disallow any portion of the Tax Credits taken by Central City for
production of Qualified Fuel; (ii) Central City becoming aware that the IRS has
questioned whether the Facility was placed in service as required by Section 29
of the Code or questioned or otherwise implicated the proprietary process
licensed hereunder; (iii) Central City becoming aware that the IRS has or may
question the production capacity of the Facility; or (iv) Central City otherwise
has reason to believe that it is more likely than not that the IRS will disallow
all or a portion of the Tax Credits. A Tax Event arising hereunder shall cease
on the earlier of (A) a Final Determination, (B) when Central City and CoBon
agree that the tax issue giving rise to the Tax Event has been resolved, or (C)
solely with respect to a Tax Event arising under clause (iv) above, the issuance
of a revenue agent's report subsequent to the Tax Event arising under clause
(iv) above which does not propose to disallow any Tax Credits taken by Central
City, or Central City determines, in its sole discretion, that the IRS does not
intend to examine, review, or adjust all or a portion of the Tax Credits.

                           2. "Final Determination" means: (i) unless an
adjustment is proposed with respect to any such Tax Credits, the expiration of
the applicable statute of limitations for the relevant tax period and taxpayer;
(ii) unless an administrative appeal or suit for refund is initiated by Central
City, the date ninety (90) days after the issuance of a notice of deficiency;
(iii) unless judicial proceedings are initiated by Central City, a final
decision with respect to the proposed adjustment by an IRS appeals officer, as
evidenced by the issuance of a 90-day letter, 870-AD or like notice and the
expiration of the period for initiating judicial proceedings; (iv) unless
appealed by Central City, a final decision with respect to the proposed
adjustment by the United States Tax Court, Court of Federal Claims or the
appropriate Federal District Court and the expiration of the period for filing

                                       11
<PAGE>

an appeal of such decision; (v) a final decision of a United States Court of
Appeals with respect to the proposed adjustment, unless a petition for
certiorari to the United States Supreme Court has been applied for and is
pending or has been granted with respect to such decision; (vi) denial of
certiorari by or final decision of the United States Supreme Court; or (vii) the
settlement of a proposed adjustment as evidenced by a closing agreement.

                  B. Earned Royalty Fee Tax Event Adjustment. Notwithstanding
any other provision contained in this Agreement to the contrary, if Central City
knows or is able to reasonably conclude that a Tax Event has or will occur, then
Central City shall immediately notify CoBon of such Tax Event (the "Tax Event
Notice") and thereafter Central City shall not be obligated to make any payments
of Earned Royalty Fees, except as follows:

                           1. If there is no longer an extant Tax Event, Central
City shall deliver to CoBon the Earned Royalty Fees that would have been payable
to CoBon after the Tax Event Notice if the Tax Event had not occurred.

                           2. Upon a Final Determination that Tax Credits are
being disallowed in whole or in part with respect to specified calendar
quarters, Central City shall deliver to CoBon an amount (the "Adjusted Earned
Royalty Fees") equal to the sum of (I) the product of (a) the Earned Royalty
Fees that would have been payable to CoBon pursuant to Section 4.3 if a Tax
Event had not occurred for such specified calendar quarters, multiplied by (b) a
fraction, the numerator of which is the amount of Tax Credits allowed to Central
City pursuant to the Final Determination minus any interest and penalties
(including substantial understatement penalties and any penalties for
underpayment of estimated taxes to the extent attributable to Tax Credits
claimed by Central City), and the denominator of which is the amount of Tax
Credits claimed by Central City, plus (II) interest at 9% per annum commencing
on the date that the Earned Royalty Fees described in clause (I) was due.

         4.5 Payment in Arrears. All payments due under Article 4, except for
any lump sum payment due thereunder (including the Accrued Earned Royalty Fees)
which shall be paid in accordance with the terms set forth above, shall be paid
in arrears based on production of Qualified Fuels at the Facility during (a)
with respect to the Initial Royalty Fee, such previous calendar month and shall
be made within fifteen (15) days following the end of each such calendar month,
and (b) with respect to the Earned Royalty Fee, such previous calendar quarter
and shall be made within fifteen (15) days following the end of each such
calendar quarter.

                           BINDER PURCHASE AND SUPPLY

         5.1. Agreement to Purchase and Sell Binder. During the term of this
Agreement, except as specifically set forth herein, Central City shall purchase
from Covol, and Covol shall supply to Central City, all of Central City's
requirements for Binder for use in the manufacture of Qualified Fuel at the
Facility . Covol shall have the right to delegate its obligation to supply
Binder to Central City pursuant to this Section 5.1 and notwithstanding such
delegation, Covol shall be liable at all times for its failure, or its
delegate's failure, to supply Binder in the quantities required by Central City.
Central City and Covol agree that the Binder to be purchased and sold under this
Agreement may include any proprietary Covol binder now or hereafter available.
Covol agrees that Central City may purchase binders from an alternative
supplier, but otherwise continue to use the Coal Technology, if (a) Covol cannot
satisfy Central City's volume requirements for Binder or (b) Central City is
required when utilizing the Coal Technology to use more than the equivalent of
two dry pounds of Binder per ton of coal feedstock in order to produce Qualified
Fuel, such determination to be made by Combustion Resources, LLC, or such other
nationally-recognized laboratory, selected by Central City and Covol by the
following process: First, the laboratory shall prepare synthetic fuel test
samples from representative samples of Central City's coal feedstock and Covol's
Binder at the rate of two dry pounds of Binder per ton of coal feedstock.
Second, utilizing generally accepted, Qualified Fuel testing procedures and
protocols, the laboratory shall determine whether a significant chemical change
has occurred such that a Qualified Fuel is produced. In any case, upon Central
City's request, Covol shall provide Central City with such support and technical
assistance in the use and proper application of Binder using the Coal Technology
to produce a marketable Qualified Fuel at the facility utilizing a rate of two
dry pounds of Binder per ton of coal feedstock. In the event that Central City
elects to purchase an alternative binder, Central City shall provide Covol with
written notice of such intent. Within ten (10) days of receipt of such notice,
Covol may give notice to Central City that (a) Covol is able to satisfy Central
City's requirement for Binder in accordance with this Section 5.1, together with
evidence reasonably satisfactory to Central City or (b) is willing to provide
more than the equivalent of two dry pounds of Binder per feedstock at a price
not greater than the Binder Price (defined below) of two dry pounds of Binder.
If Covol provides notice of its intention to cure its performance under this
Section 5.1 and such cure is effected within twenty (20) days after Covol's
receipt of notice from Central City, then Central City's obligation to purchase
Binder from Covol under this Section 5.1 will be reinstated, subject to the
terms and conditions set forth herein; provided, however, that Covol may not
provide such notice and obtain such reinstatement more than once in any twelve
month period or more than three times during the term of this Agreement.

         5.2. Binder Price and Payment. The price of Binder purchased by Central
City (the "Binder Price") shall be comprised of the Cost Basis and the Profit
Basis. "Cost Basis" shall mean Covol's direct and actual costs (including, but
not limited to material, labor and transportation costs) of manufacturing and
delivering Binder, plus a reasonable allocation of overhead, provided that until
December 31, 2003, in no event shall such cost exceed $**** per ton of Qualified

                                       13
<PAGE>

Fuel manufactured by Central City at the Facility. Covol shall provide Central
City with supporting documentation sufficient to allow Central City to verify
such calculation. "Profit Basis" shall mean the product of **** ($****) per ton
of Qualified Fuel manufactured by Central City at the Facility. The Cost Basis
of the Binder Price shall be paid within thirty (30) days after Central City's
receipt of an invoice. The Profit Basis of the Binder Price shall be paid in
arrears based on production of Qualified Fuels at the Facility during such
previous calendar month and shall be made within fifteen (15) days following the
end of each such calendar month. Central City will only be required to pay for
Binder actually purchased from Covol under this Agreement.

         5.3. Binder Certification. In connection with Covol's sale and delivery
of Binder, Covol certifies, and shall provide Central City with further written
certification upon request, that the Binder quality and chemical makeup is
consistent with the quality and makeup of Binder described on the attached
Exhibit D, and as set forth in that certain Letter Agreement by and between
Covol and CoBon dated November 11, 1999 (a copy of which is attached hereto as
Exhibit C). Such formulation certification shall be based upon independent,
random sample testing conducted at the time of Binder production.

         5.4. Representations and Warranties. Covol hereby acknowledges that
Central City has, and is entitled to, rely on all its representations and
warranties contained in the License Agreement (as amended to date) with respect
to, and relating to, the Binder, and hereby reaffirms such representations and
warranties.

                                    ARTICLE 6
                              TERM AND TERMINATION

         6.1. Term. This Agreement shall expire on December 31, 2007, unless a
Congressional extension of applicable Section 29 tax credit legislation is
enacted, in which case the term of this Agreement shall, upon written agreement
of the parties hereto, be extended by an equal period of time.

         6.2. Termination. Unless earlier terminated by CoBon or Central City
upon thirty (30) days' advance written notice for cause (including but not
limited to an Event of Default hereunder), this Agreement shall terminate upon
the expiration date set forth in Section 6.1. Upon termination of this
Agreement, all rights granted hereunder and obligations to the parties shall
immediately cease; however, termination shall not relieve either party of its
obligations accrued during the Term of this Agreement which have not been
fulfilled.

                              EMPLOYMENT AGREEMENT

                  THIS AGREEMENT is entered into as of October 25, 2002, by and
between KIRK A. BENSON (the "Employee") and HEADWATERS INCORPORATED, a Delaware
corporation (the "Company").

         1. Duties and Scope of Employment.

         (a) Position. For the term of his employment under this Agreement (the
"Employment"), the Company agrees to employ the Employee in the position of
Chairman and Chief Executive Officer. The Employee shall report to the Company's
Board of Directors (the "Board").

         (b) Obligations to the Company. During his Employment, the Employee
shall devote his full business efforts and time to the Company. During his
Employment, without the prior written approval of the Board, the Employee shall
not render services in any capacity to any other person or entity and shall not
act as a sole proprietor or partner of any other person or entity or as a
shareholder owning more than five percent of the stock of any other corporation;
provided that the Employee may devote a reasonable amount of time to charitable,
educational, civic and political activities. The Employee shall comply with the
Company's policies and rules, as they may be in effect from time to time during
his Employment.

         (c) No Conflicting Obligations. The Employee represents and warrants to
the Company that he is under no obligations or commitments, whether contractual
or otherwise, that are inconsistent with his obligations under this Agreement.
The Employee represents and warrants that he will not use or disclose, in
connection with his Employment, any trade secrets or other proprietary
information or intellectual property in which the Employee or any other person
has any right, title or interest and that his Employment will not infringe or
violate the rights of any other person.

         2. Cash and Incentive Compensation.

         (a) Salary. The Company shall pay the Employee as compensation for his
services a base salary at a gross annual rate of not less than (i) $400,000 for
the 12-month period ending April 24, 2003, (ii) $450,000 for the 12-month period
ending April 24, 2004, and (iii) $500,000 for the 12-month period ending April
24, 2005. Such salary shall be payable in accordance with the Company's standard
payroll procedures. (The annual compensation specified in this Subsection (a),
together with any increases in such compensation that the Company may grant from
time to time, is referred to in this Agreement as "Base Salary.")

         (b) Incentive Bonuses. The Employee shall be eligible to be considered
for an annual incentive bonus. Such bonus shall be awarded based on objective or
subjective criteria established in advance by the Board or the Compensation
Committee of the Board. The determinations of the Board or its Compensation
Committee with respect to such bonus shall be final and binding. The foregoing
notwithstanding, as long as the Company's Incentive Bonus Plan, as approved by
the Board on November 10, 2001 (the "2001 Incentive Plan") remains applicable,
the Employee's "bonus percent" within the meaning of such Plan shall not be less
than 110%. If the Company replaces the 2001 Incentive Plan with a new program,
the Employee's opportunity to earn a bonus under the new program shall at least

                                       1
<PAGE>

be equivalent to the opportunity that he enjoyed under the 2001 Incentive Plan.
Upon termination of Employment for any reason, the Employee shall be eligible to
receive a prorated bonus for the year of termination and any previously withheld
or "banked" bonuses, subject in each case to the generally applicable terms and
conditions of the 2001 Incentive Plan (or its successor) and to the
determinations of the Board or its Compensation Committee; provided, however, if
the Employee retires from Employment after having attained age 57 and has not
been terminated for Cause, then previously withheld or "banked" bonuses shall be
immediately paid to the Employee notwithstanding the terms of the 2001 Incentive
Plan (or its successor).

         (c) Stock Option Grants.

         (i) February 2003 Grant. Subject to availability under a stock
incentive plan of the Company that is approved by the stockholders, on or
promptly after the date of the next regular annual meeting of the Company's
stockholders, the Company shall grant the Employee a stock option covering a
number of shares of the Company's Common Stock equal to the greater of (A)
164,000 or (B) the number that, when combined with the option covering 61,000
shares that was granted to the Employee on June 10, 2002, will have a value
equal to the value of a hypothetical option covering 225,000 shares granted to
the Employee on June 10, 2002. For purposes of the preceding sentence, the value
of options shall be determined by the same methodology and assumptions used for
purposes of footnote disclosure in the Company's financial statements for the
year ending September 30, 2002. The option granted under this Paragraph (i)
shall become exercisable in three equal installments on March 31, 2003, March
31, 2004, and March 31, 2005, provided that the Employee's Employment continues
until the date in question.

         (ii) April 2003 Grant. Subject to availability under a stock incentive
plan of the Company approved by the stockholders, on or promptly after April 24,
2003, the Company shall grant the Employee a stock option covering 137,500
shares of the Company's Common Stock. The option granted under this Paragraph
(ii) shall become exercisable in three equal installments on April 24, 2004,
April 24, 2005, and April 24, 2006, provided that the Employee's Employment
continues until the date in question.

         (iii) April 2004 Grant. Subject to availability under a stock incentive
plan of the Company approved by the stockholders, on or promptly after April 24,
2004, the Company shall grant the Employee a stock option covering 137,500
shares of the Company's Common Stock. The option granted under this Paragraph
(iii) shall become exercisable in three equal installments on April 24, 2005,
April 24, 2006, and April 24, 2007, provided that the Employee's Employment
continues until the date in question.

         (iv) Other Option Terms. The exercise price per share of each option
granted under this Subsection (d) shall be equal to the fair market value per
share of the Company's Common Stock on the date of grant. The term of each such
option shall be 10 years, provided that each such option may expire earlier if
the Employee's Employment terminates, but not less than (A) 3 months after the
termination of his Employment for any reason other than death or disability; (B)
12 months after termination of his Employment because of death; and (C) 6 months
after termination of his Employment because of his total and permanent
disability. All share numbers set forth in this Subsection (d) shall
automatically be adjusted to reflect stock splits, stock dividends, reverse
stock splits, and similar events.

                                       2
<PAGE>

         (v) Substitution of Other Equity Grants. In lieu of all or part of the
stock options described in Paragraphs (i), (ii) and (iii) above, the Company may
grant the Employee equity in the Company in other forms, provided that (A) the
equity grants in other forms have a value not less than the value of such
options and (B) the Employee consents in writing to the substitution of other
equity grants for such options.

         (d) Reimbursement of Legal Fees. The Company shall reimburse the
Employee for the reasonable cost of retaining counsel to assist him in the
preparation and negotiation of this Agreement in an amount not to exceed $5,000.

         3. Vacation and Employee Benefits. During his Employment, the Employee
shall be eligible for paid vacations in accordance with the Company's vacation
policy, as it may be amended from time to time. The Employee shall be eligible
to participate in the employee benefit plans maintained by the Company, subject
in each case to the generally applicable terms and conditions of the plan in
question and to the determinations of any person or committee administering such
plan. The Employee shall also be entitled to any other perquisites that the
Company makes available to its executive officers.

         4. Business Expenses. During his Employment, the Employee shall be
authorized to incur necessary and reasonable travel, entertainment and other
business expenses in connection with his duties hereunder. The Company shall
reimburse the Employee for such expenses upon presentation of an itemized
account and appropriate supporting documentation, all in accordance with the
Company's generally applicable policies.

         5. Term of Employment.

         (a) Termination of Employment. The Company may terminate the Employee's
Employment at any time and for any reason (or no reason), and with or without
Cause, by giving the Employee notice in writing. The Employee may terminate his
Employment by giving the Company notice in writing. The Employee's Employment
shall terminate automatically in the event of his death. The termination of the
Employee's Employment shall not limit or otherwise affect his obligations under
Section 7.

         (b) Employment at Will. The Employee's Employment with the Company
shall be "at will," meaning that either the Employee or the Company shall be
entitled to terminate the Employee's Employment at any time and for any reason,
with or without Cause. Any contrary representations that may have been made to
the Employee shall be superseded by this Agreement. This Agreement shall
constitute the full and complete agreement between the Employee and the Company
on the "at will" nature of the Employee's Employment, which may only be changed
in an express written agreement signed by the Employee and a duly authorized
officer of the Company.

         (c) Rights Upon Termination. Except as expressly provided in Section 6,
upon the termination of the Employee's Employment, the Employee shall only be
entitled to the compensation, benefits and expense reimbursements that the
Employee has earned under this Agreement before the effective date of the
termination. The payments under this Agreement shall fully discharge all
responsibilities of the Company to the Employee.

         6. Termination Benefits.

         (a) General Release. Any other provision of this Agreement
notwithstanding, Subsections (b), (c) and (d) below shall not apply unless the
Employee (i) has executed a mutual release of all claims and (ii) has returned
all property of the Company in the Employee's possession.

         (b) Severance Pay. If the Company terminates the Employee's Employment
for any reason other than Cause, or if the Employee resigns all of his positions
with the Company for Good Reason, then the Company shall immediately make a lump
sum severance payment to the Employee in an amount equal to 300% of his annual
Base Salary (at the rate in effect when his Employment terminates).

         (c) Option Acceleration. If Subsection (b) above applies, all options
to purchase shares of the Company's stock that the Employee then holds shall
immediately become fully vested and exercisable.

         (d) Health Insurance. If Subsection (b) above applies, and if the
Employee elects continuation health insurance coverage under the Consolidated
Omnibus Budget Reconciliation Act ("COBRA") following the termination of his
Employment, then the Company shall pay the monthly premium under COBRA for the
Employee and his dependents until the earliest of (i) the date that is 18 months
after the Employee's termination of his Employment, (ii) the expiration of the
Employee's continuation coverage under COBRA or (iii) the date when the Employee
receives substantially equivalent health insurance coverage in connection with
new employment or self-employment ("replacement coverage"). To the extent that
the Employee is not receiving replacement coverage after the expiration of the
COBRA continuation period, then the Company shall reimburse the Employee, on a
monthly basis, for the cost of obtaining such coverage on an individual basis
for up to an additional 18 months and in an amount not to exceed the cost of the
last monthly COBRA premium paid by the Company on the Employee's behalf.

         (e) Definition of "Cause." For all purposes under this Agreement,
"Cause" shall mean:

                  (i) An unauthorized use or disclosure by the Employee of the
         Company's confidential information or trade secrets, which use or
         disclosure causes material harm to the Company;

                  (ii) A willful act by the Employee which constitutes gross
         misconduct or fraud and which is materially injurious to the Company;

                  (iii) The Employee's conviction of, or plea of "guilty" or "no
         contest" to, a felony under the laws of the United States or any state
         thereof; or

                  (iv) A willful failure by the Employee to substantially
         perform his duties under this Agreement, other than a failure resulting
         from the Employee's complete or partial incapacity due to physical or
         mental illness.

The foregoing shall not be deemed an exclusive list of all acts or omissions
that the Company may consider as grounds for the termination of the Employee's
Employment with Cause. No act, or failure to act, by the Employee shall be
considered "willful" unless committed without good faith and without a
reasonable belief that the act or omission was in the Company's best interest.

                                       4

         (f) Definition of "Good Reason." For all purposes under this Agreement,
"Good Reason" shall mean that the Employee has not been terminated for Cause and
elects to resign after one or more of the following events:

                  (i) The reduction of the Employee's Base Salary;

                  (ii) The diminution or reduction of Employee's title,
         authority, duties or responsibilities, including (without limitation)
         the Employee's removal from his position as the Company's Chief
         Executive Officer;

                  (iii) The Employee, at any time after the Company has been
         subject to a Change in Control (as defined in Section 7), is assigned
         to any position other than the position of Chief Executive Officer of a
         corporation whose equity securities are regularly traded on a national
         securities exchange or the Nasdaq National Market;

                  (iv) The relocation of the Employee's principal place of
         employment by more than 25 miles from its present location; or

                  (v) Any breach by the Company of any material provision of
         this Agreement.

         7. Change in Control.

         (a) Option Acceleration. If the Company is subject to a Change in
Control, all options to purchase shares of the Company's stock that the Employee
then holds shall immediately become fully vested and exercisable.

         (b) Definition of "Change in Control." For all purposes under this
Agreement, "Change in Control" shall mean:

                  (i) The consummation of a merger or consolidation of the
         Company with or into another entity or any other corporate
         reorganization, if persons who were not stockholders of the Company
         immediately prior to such merger, consolidation or other reorganization
         own immediately after such merger, consolidation or other
         reorganization 50% or more of the voting power of the outstanding
         securities of each of (A) the continuing or surviving entity and (B)
         any direct or indirect parent corporation of such continuing or
         surviving entity;

                  (ii) The sale, transfer or other disposition of all or
         substantially all of the Company's assets;

                  (iii) A change in the composition of the Board, as a result of
         which fewer than 50% of the incumbent directors are directors who
         either:

                           (A) Had been directors of the Company on the date 24
                  months prior to the date of such change in the composition of
                  the Board (the "Original Directors"); or

                                       5
<PAGE>

                           (B) Were appointed to the Board, or nominated for
                  election to the Board, with the affirmative votes of at least
                  a majority of the aggregate of (I) the Original Directors who
                  were in office at the time of their appointment or nomination
                  and (II) the directors whose appointment or nomination was
                  previously approved in a manner consistent with this
                  Subparagraph (B); or

                  (iv) Any transaction as a result of which any person is the
         "beneficial owner" (as defined in Rule 13d-3 under the Securities
         Exchange Act of 1934), directly or indirectly, of securities of the
         Company representing at least 50% of the total voting power represented
         by the Company's then outstanding voting securities. For purposes of
         this Paragraph (iv), the term "person" shall have the same meaning as
         when used in sections 13(d) and 14(d) of the Securities Exchange Act of
         1934 but shall exclude (A) a trustee or other fiduciary holding
         securities under an employee benefit plan of the Company or of a parent
         or subsidiary of the Company and (B) a corporation owned directly or
         indirectly by the stockholders of the Company in substantially the same
         proportions as their ownership of the common stock of the Company.

A transaction shall not constitute a Change in Control if its sole purpose is to
change the state of the Company's incorporation or to create a holding company
that will be owned in substantially the same proportions by the persons who held
the Company's securities immediately before such transaction.

         8. Successors.

         (a) Company's Successors. This Agreement shall be binding upon any
successor (whether direct or indirect and whether by purchase, lease, merger,
consolidation, liquidation or otherwise) to all or substantially all of the
Company's business and/or assets. For all purposes under this Agreement, the
term "Company" shall include any successor to the Company's business and/or
assets which becomes bound by this Agreement.

         (b) Employee's Successors. This Agreement and all rights of the
Employee hereunder shall inure to the benefit of, and be enforceable by, the
Employee's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

                                       6

         9. Arbitration.

         (a) Scope of Arbitration Requirement. The parties hereby waive their
rights to a trial before a judge or jury and agree to arbitrate before a neutral
arbitrator any and all claims or disputes arising out of this Agreement and any
and all claims arising from or relating to the Employee's Employment, including
(but not limited to) claims against any current or former employee, director or
agent of the Company, claims of wrongful termination, retaliation,
discrimination, harassment, breach of contract, breach of the covenant of good
faith and fair dealing, defamation, invasion of privacy, fraud,
misrepresentation, constructive discharge or failure to provide a leave of
absence, or claims regarding commissions, stock options or bonuses, infliction
of emotional distress or unfair business practices.

         (b) Procedure. The arbitrator's decision shall be written and shall
include the findings of fact and law that support the decision. The arbitrator's
decision shall be final and binding on both parties, except to the extent
applicable law allows for judicial review of arbitration awards. The arbitrator
may award any remedies that would otherwise be available to the parties if they
were to bring the dispute in court. The arbitration shall be conducted in
accordance with the National Rules for the Resolution of Employment Disputes of
the American Arbitration Association; provided, however that the arbitrator
shall allow the discovery that the arbitrator deems necessary for the parties to
vindicate their respective claims or defenses. The arbitration shall take place
in Salt Lake County, Utah, or, at the Employee's option, the county in which the
Employee primarily worked with the Company at the time when the arbitrable
dispute or claim first arose.

         (c) Costs. The parties shall share the costs of arbitration equally.
Both the Company and the Employee shall be responsible for their own attorneys'
fees, and the arbitrator may not award attorneys' fees unless a statute or
contract at issue specifically authorizes such an award.

         (d) Applicability. This Section 9 shall not apply to (i) workers'
compensation or unemployment insurance claims or (ii) claims concerning the
validity, infringement or enforceability of any trade secret, patent right,
copyright or any other trade secret or intellectual property held or sought by
either the Employee or the Company.

         10. Miscellaneous Provisions.

         (a) Notice. Notices and all other communications contemplated by this
Agreement shall be in writing and shall be deemed to have been duly given when
personally delivered or when mailed by U.S. registered or certified mail, return
receipt requested and postage prepaid. In the case of the Employee, mailed
notices shall be addressed to him at the home address that he most recently
communicated to the Company in writing. In the case of the Company, mailed
notices shall be addressed to its corporate headquarters, and all notices shall
be directed to the attention of its Secretary.

         (b) Modifications and Waivers. No provision of this Agreement shall be
modified, waived or discharged unless the modification, waiver or discharge is
agreed to in writing and signed by the Employee and by an authorized officer of
the Company (other than the Employee). No waiver by either party of any breach
of, or of compliance with, any condition or provision of this Agreement by the
other party shall be considered a waiver of any other condition or provision or
of the same condition or provision at another time.

         (c) Whole Agreement. No other agreements, representations or
understandings (whether oral or written and whether express or implied) that are
not expressly set forth in this Agreement have been made or entered into by
either party with respect to the subject matter hereof. This Agreement contains
the entire understanding of the parties with respect to the subject matter
hereof.

         (d) Withholding Taxes. All payments made under this Agreement shall be
subject to reduction to reflect taxes or other charges required to be withheld
by law.

         (e) Choice of Law and Severability. This Agreement shall be interpreted
in accordance with the laws of the State of Utah (except their provisions
governing the choice of law). If any provision of this Agreement becomes or is
deemed invalid, illegal or unenforceable in any applicable jurisdiction by
reason of the scope, extent or duration of its coverage, then such provision
shall be deemed amended to the minimum extent necessary to conform to applicable
law so as to be valid and enforceable or, if such provision cannot be so amended
without materially altering the intention of the parties, then such provision
shall be stricken and the remainder of this Agreement shall continue in full
force and effect. If any provision of this Agreement is rendered illegal by any
present or future statute, law, ordinance or regulation (collectively the
"Law"), then such provision shall be curtailed or limited only to the minimum
extent necessary to bring such provision into compliance with the Law. All the
other terms and provisions of this Agreement shall continue in full force and
effect without impairment or limitation.

         (f) No Assignment. This Agreement and all rights and obligations of the
Employee hereunder are personal to the Employee and may not be transferred or
assigned by the Employee at any time. The Company may assign its rights under
this Agreement to any entity that assumes the Company's obligations hereunder in
connection with any sale or transfer of all or a substantial portion of the
Company's assets to such entity.

         (g) Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         IN WITNESS WHEREOF, each of the parties has executed this Agreement, in
the case of the Company by its duly authorized officer, as of the day and year
first above written.
