ARTICLE II
PURCHASE AND SALE

2.1. Purchase and Sale.

(a) Buyer and Sellers hereby agree that at the Closing, and
upon all of the terms and subject to all of the conditions of this Agreement,
Sellers shall sell, convey, transfer and assign to Buyer, and Buyer shall
purchase and accept from Sellers, all of the Assets, free and clear of all
Liens.

(b) Buyer and Sellers hereby agree that at the Closing, and
upon all of the terms and subject to all of the conditions of this Agreement,
Sellers shall assign to Buyer the Contracts and all rights arising thereunder.

2.2. Payment of the Initial Purchase Consideration; Holdback Amount.

(a) In consideration of Sellers' sale, conveyance, transfer,
delivery and assignment of the Assets and Contracts, at the Closing, Buyer shall
(i) pay to the Sellers Nine Million Six Hundred Eighty-Five Thousand Dollars
($9,685,000.00) (the "Initial Purchase Consideration") and (ii) hold in a
non-segregated account the amount of Three Hundred Fifteen Thousand Dollars
($315,000.00) (the "Holdback Amount"), which amount shall be disbursed in
accordance with Section 2.2(b) hereof. The Initial Purchase Consideration and
the Surplus (as defined below), if any (collectively, the "Purchase
Consideration"), shall be paid to the Sellers by wire transfer in readily
available funds to First Security Bank; Salt Lake City, Utah; 18A 124 000012;
for the account of Covol Technologies, Inc.; Acct. #0600019939.

(b) At the time of Sellers' delivery of the Assets to the
Site, Buyer shall inspect the Assets and notify Sellers, in writing, of any
missing equipment or damage to the Assets. Upon completion of the assembly of
the Facility (including any required repairs), Buyer shall present Seller with a
notice (the "Holdback Claim Notice") stating the costs of such repairs (the
"Holdback Claim"). The amount of the Holdback Claim shall be applied by Buyer
against the Holdback Amount by notice by Buyer to Sellers. If the amount of the
Holdback Claim made by Buyer is less than the Holdback Amount (the difference
being referred to herein as a "Surplus"), Buyer shall pay an amount equal to the
Surplus to Sellers within five days of the determination of the amount of the
Surplus. If the amount of the Holdback Claim made by Buyer is greater than the
Holdback Amount (the difference being referred to herein as a

"Deficiency"), Sellers shall pay to Buyer the amount of such Deficiency within
five days of the determination of the amount of the Deficiency. Alternatively,
if the payment of the Deficiency is not paid by Sellers to Buyer within five
days of the determination of the amount of the Deficiency, Buyer shall have the
right to set-off the amount of the Deficiency against any royalty payments that
Buyer may become obligated to pay to Covol pursuant to Section 3 of the License
and Binder Purchase Agreement.

(c) Notwithstanding the foregoing, if Sellers notify Buyer of
their disagreement with the Holdback Claim Notice within seven business days of
receiving such notice, a committee consisting of two officers designated by
Buyer and two officers designated by Sellers shall meet and attempt in good
faith to resolve such dispute. If such committee does not resolve the dispute
within seven business days following their initial meeting, then a single third
party engineer (the "Third Party Engineer") shall be designated to consider and
decide the issues raised by such dispute, unless both parties determine that
further discussions by the committee are merited. The selection of such Third
Party Engineer shall be made from the list of engineers set forth in Schedule
2.2 attached hereto. In selecting the Third Party Engineer, each party (starting
with Sellers for the first dispute and alternating between Sellers and Buyer for
each dispute thereafter) shall alternate in deleting one name from the list of
engineers until only one such engineer shall remain, which remaining engineer
shall be the Third Party Engineer. The Third Party Engineer shall be designated
from such list not later than the third business day following the expiration of
the second seven business day period described above and such designation shall
become effective on the third business day following such designation. In the
event that the Third Party Engineer so designated does not or is unable to serve
as such, the selection process shall be commenced again until a replacement
Third Party Engineer is so designated. Within ten business days of the
effectiveness of the designation of a Third Party Engineer, each of the Buyer
and Sellers shall submit to the Third Party Engineer a notice (a "Position
Notice") setting forth in detail such party's position in respect of the issues
in dispute. Such Position Notice shall include supporting documentation, if
appropriate.

(d) The Third Party Engineer shall complete all proceedings
and issue its decision with regard to the issues in dispute, which decision
shall be binding on the parties, as promptly as reasonably possible, but in any
event within ten business days of the date on which both Position Notices are
submitted, unless the Third Party Engineer reasonably determines that additional
time is required in order to give adequate consideration to the issues raised.
In such case, the Third Party Engineer shall state in writing his reasons for
believing that additional time is needed and shall specify the additional period
required, which period shall not exceed ten days without the Buyer's and
Sellers' agreement.

2.3. Deliveries at Closing.

(a) By Sellers to Buyer. At the Closing, in addition to the
Assets, Sellers shall deliver the following items to Buyer, each properly

Sellers' Counsel, (vi) Sellers' Closing Certificate, (vii) the Acknowledgment

applicable to Buyer, (iv) Buyer's Closing Certificate and (v) a certificate of
the corporate secretary (or equivalent official) of Buyer as to such matters as

2.4. Allocation of Purchase Price.

On the Closing Date, or at a later time agreed to by the parties, not
to exceed 30 days following the Closing Date, the purchase price shall be
allocated among the Assets and Contracts in accordance with Exhibit F attached
hereto. Such allocation shall be intended to comply with the requirements of
Section 1060 of the Code, and no party shall take any position inconsistent with
such allocation for income tax purposes, except that Buyer's cost for the Assets
and Contracts may differ from the amount so allocated to the extent necessary to
reflect Buyer's capitalized acquisition costs other than the amount realized by
Sellers.

2.5. No Assumption of Liabilities.

Buyer does not and will not assume any liability or obligation of any
kind of Sellers, or any obligation relating to the use of the Assets or
performance by Sellers under the Contracts prior to the Effective Time, whether

unknown, or otherwise.

2.6. Sales Tax Exemption.

To the extent applicable, at the Closing, Buyer will deliver to Sellers
appropriate and customary sales tax exemption certificates relating to the
transfer of the Assets and the assignment of the Contracts contemplated hereby.

liability, contingent or otherwise, for brokers or finders fees created by

provided, however, that Section 5-1401 of the New York General Obligations Law
shall apply to this Agreement. Each of the parties hereto, in respect of itself
and its properties, agree to be subject to (and hereby irrevocably submits to)
the nonexclusive jurisdiction of the United States federal court for the
Southern District of New York or New York state court sitting in the Borough of
Manhattan, New York, in respect of any suit, action or proceeding arising out of
or relating to this Agreement or the transactions contemplated herein, and
irrevocably agrees that all claims in respect of any such suit, action or
proceeding may be heard and determined in any such court. Each of the parties
hereto irrevocably waives, to the fullest extent it may effectively do so under
applicable Law, any objection to the laying of the venue of any such suit,
action or proceeding brought in any such court and any claim that any such suit,
action or proceeding brought in any such court has been brought in an
inconvenient forum. Either party hereto may make service on the other party by

sending or delivering a copy of the process to the party to be served at the
address and in the manner provided for the giving of notices in Section 10.5
hereof. Nothing in this Section, however, shall affect the right of any party to
bring any action or proceeding arising out of or relating to this Agreement in
any other court or to serve legal process in any other manner permitted by law
or in equity.

10.4. Assignment.

assigned, by operation of law or otherwise, without the prior written consent of
the other party provided, however, that Buyer may assign this Agreement to an
Affiliate of Buyer without the consent of Sellers.
