NOW THEREFORE, in consideration of the mutual promises and covenants contained herein,

the Parties hereby agree as follows:

ARTICLE 1

EXCLUSIVITY

1.1

Basic Agreement. During the Exclusivity Period (as defined in Section 1.5 hereof): (A)

Mattson agrees that MesoCoat shall have an exclusive right to incorporate in MesoCoat Products and sell

(as so incorporated but not independent of a MesoCoat Product except as a spare part for a Vortek Lamp

previously incorporated in a MesoCoat Product) the Vortek Lamp in the market for wear reducing and

corrosion resistant coatings, claddings & related surface treatments (the “Market”) under the conditions

set forth herein; (B) MesoCoat shall purchase Vortek Lamps in accordance with the terms hereof and,

upon its signature, with the terms of the Supply Agreement, and MesoCoat Products shall incorporate no

other lamps having functionality comparable to the Vortek Lamp; (C) Mattson shall not manufacture,

make, have made or sell for or to any unrelated third party (other than customers of MesoCoat) the Vortek

Lamp or any product with functionality similar to the Vortek Lamp for inclusion in any product with a use

falling within the Market or otherwise comparable to that of the MesoCoat Products; and (D) Mesocoat

will not develop or cause or permit to be developed, either by MesoCoat alone or with or through another

party or parties, any product with a similar functionality to the Vortek Lamp. Notwithstanding the

preceding sentence, if MesoCoat and Mattson shall not have agreed to an extension of the term of the

Supply Agreement during the last two years of term of the Supply Agreement, MesoCoat may develop or

contract with others to develop products with similar functionality to the Vortek Lamp upon written notice

to Mattson, which event the Exclusivity Period shall expire upon such notice. In no event will MesoCoat

sell or cause to be sold (or otherwise transferred in any way) to any customer or end-user a lamp so

developed prior to the end of the Exclusivity Period. For purposes of this Agreement, lamps ***.and which

are not *** shall not be considered to be similar to the Vortek Lamp and the prohibitions upon Mattson

and MesoCoat under this Agreement accordingly shall not apply to ***.

1.1

Manufacturing Rights. During this same Exclusivity Period, Mattson will have the sole

and exclusive right to manufacture (or cause to be manufactured) at ▇▇▇▇▇▇▇’▇ sole cost and expense each

Vortek Lamp and all components thereof. MesoCoat will not, and will not knowingly cause or permit any

third party to, manufacture Vortek Lamps or any components thereof.

1.2

Manufacturing Rights. During this same Exclusivity Period, Mattson will have the sole

and exclusive right to manufacture (or cause to be manufactured) at ▇▇▇▇▇▇▇’▇ sole cost and expense each

Vortek Lamp and all components thereof. MesoCoat will not, and will not knowingly cause or permit any

third party to, manufacture Vortek Lamps or any components thereof.

Exchange Commission. Confidential treatment has been requested with respect to the omitted

portions

1.3

License. During the Exclusivity Period, Mattson hereby grants an exclusive license to

MesoCoat to purchase Vortek Lamps and incorporate them in MesoCoat Products, which license may be

sublicensed to MesoCoat’s customers, but solely to the extent necessary to enable use (and not sale or

distribution) by any such customer of the MesoCoat Product purchased by it; provided, however, that

neither MesoCoat nor any of its customers shall have any right to manufacture a Vortek Lamp or any

component thereof. Except as set forth above, MesoCoat shall not seek to develop itself or otherwise create

(or have developed or otherwise created) any improvement or other derivative of a Vortek Lamp or any

portion thereof at any tiem before or after the end of the Exclusivity Period. If, notwithstanding the

foregoing, MesoCoat shall so develop or create any improvement or other derivative of a Vortek Lamp

during the Exclusivity Period, it shall be owned exclusively by Mattson and will not be licensed for sale

hereunder. During the Agreement Term, MesoCoat shall have the exclusive right to market, sell, and/or

distribute Vortek Lamps in the Market, in the form incorporated in MesoCoat Products or as spare parts

therefor, but not without being so incorporated (except for spare parts for Vortek Lamps previously

incorporated in MesoCoat Products)). Except as set forth in this Section, Mattson grants no license

hereunder to MesoCoat or any customer of MesoCoat to any know-how, trade secret, patent or copyright

included in Mattson Separate Intellectual Property.

1.4

Minimum Sales. During the Exclusivity Period, MesoCoat agrees to use its best efforts

to sell MesoCoat Products incorporating Vortek Lamps in the Market. If MesoCoat fails to purchase from

Mattson (including full payment of any deposits and other amounts required to be paid in the year in

question) for use in MesoCoat Products in the Market at least the number of Vortek Lamps set forth in the

below table during the year set forth next to that number in the aggregate from the date hereof until the end

of each year mentioned in the table below, the exclusivity period hereunder (the “Exclusivity Period”)

will end on the last day of that year; provided, however, that the Exclusivity Period shall be extended, and

the beginning and end of each succeeding year below shall be extended, in each case for the length of time

during which Mattson is unable to produce and deliver the Vortek Lamps in the quantities ordered.

1.5

Rights upon Termination. Upon termination of the Exclusivity Period, and without

limiting the generality of the other provisions of this Section, MesoCoat shall retain the non-exclusive right

to purchase, market, sell, and distribute Vortek Lamps incorporated in MesoCoat Products or as spare parts

therefor (but not otherwise), but shall no longer have the sole and exclusive right to market, sell, and

distribute Vortek Lamps or spare parts in the Market. Notwithstanding the above Mattson agrees not to sell

the custom lamphead design as configured for and funded by MesoCoat to any other party; provided,

however, that MesoCoat acknowledges that this Mattson agreement only concerns the precise manner that

the lamphead is configured, and not the purpose of that configuration. By way of illustration rather than

limitation of the foregoing, Mattson agrees not to sell the lamphead design as configured for MesoCoat for

use inside a pipe, but may sell a Vortek Lamp for use inside a pipe if configured differently, it being

understood that this sentence does not ▇▇▇▇▇ ▇▇▇▇▇▇▇ a license or any other rights to use intellectual

property of MesoCoat or any other party. MesoCoat agrees that Mattson owns and shall own all

intellectual property rights in each Vortek Lamp design as configured for and funded by MesoCoat as part

of the Development, it being understood that Mattson shall not acquire ownership of any MesoCoat

Separate Intellectual Property.

1.6

Exclusivity Fee. For the exclusive rights that Mattson grants MesoCoat hereunder, as

limited hereby, MesoCoat will pay Mattson an Exclusivity Fee of two million US Dollars (US$

2,000,000). The Exclusivity Fee will be due and payable in five equal installments, without interest, with

the first installment of US$400,000 due and payable *** after the first Vortek Lamp has successfully

operated incorporated in a MesoCoat Product, and the other installments of $US400,000 each due and

payable on or before the last day of each *** beginning on such initial payment; provided that the due date

of an installment shall be extended by the length of any delay in excess of standard lead times in the

delivery of Vortek Lamps to MesoCoat during the *** prior to such due date. Accordingly, the last such

installment will be due and payable on *** of such initial payment date, unless so extended. Any default in

the timely payment of an installment of this Exclusivity Fee which is not cured within *** of written

notice hereof, shall, without notice or opportunity to cure, terminate the Exclusivity Period.

1.7

Intellectual Property. Mattson and MesoCoat agree that:

(a) Any intellectual property associated with the Vortek Lamp, created as part of

the Development, and whether funded by MesoCoat or not, shall remain the property of

Mattson.

(b) Intellectual property created developed or owned by either party before the

commencement of the Development or concurrently with, but not as a part of the

Development, will remain the sole intellectual property of that party (“Separate

Intellectual Property”). The parties agree that the pipe transport system which moves

the lamphead relative to the pipe, the lamp support structure which houses the lamp, and

the air knife and extraction system, are Separate Intellectual Property of MesoCoat.

1.8

Publicity and Attribution. Neither party shall make any press release or other public

disclosure or announcement related to the sale of the Vortek Lamps by Mattson to MesoCoat, or to the

nature of the exclusivity provided by this Agreement, without the prior written approval of the other party.

The parties shall not mention or graphically or otherwise portray any portion of the other party’s products

in any manner on its web site or in any marketing brochures or other sales or marketing materials without

the prior written approval of the other party. Any such mention or portrayal by MesoCoat, after such

approval, shall include the following language or alternative language to be approved by Matttson

identifying the Vortek Lamp as ▇▇▇▇▇▇▇’▇ proprietary product: “▇▇▇▇▇▇▇ Technology, Inc. is the exclusive

supplier to MesoCoat of Vortek Lamps and spare parts.”

ARTICLE 2

SALE OF VORTEK LAMPS

2.1

Supply Agreement. Except to the extent explicitly in conflict with a clause herein, in

which case that clause will apply, the Supply Agreement will apply to sales of Vortek Lamps hereunder.

Sections 2.2 through 2.3 hereof are hereby deemed to take priority over any conflicting provision of the

Supply Agreement. The parties agree to enter into the Supply Agreement (a) with a term of ***; (b) with

base pricing *** per lamphead and *** per service module; (c) with pricing of *** per set of electrodes,

*** for a new quartz tube, and *** for a recleaned quartz tube; (d) with a retipping fee of *** per tip; (e)

with a warranty of *** on Vortek Lamps and *** months on spare parts, in each case excluding

consumables; (f) with an obligation on the part of Mattson to continue to support and provide spare parts to

MesoCoat for MesoCoat’s installed base of Vortek Lamps following the termination of the Supply

Agreement provided that MesoCoat does not sell arc lamps outside of the Market and (g) on other

commercially reasonable terms and conditions as promptly as practicable after the date of this Agreement.

2.2

Payment Terms. MesoCoat shall pay a deposit of 50% of the price of the Vortek

Lamp(s) ordered at the time of each order, and 40% of the price within five business days after shipment of

the Vortek Lamp to MesoCoat. The final 10% of the price of each Vortek Lamp shall be due and payable

immediately upon its acceptance by MesoCoat. Notwithstanding the foregoing, MesoCoat shall make

payment for the first two Vortek Lamps sold hereunder, 25% at the time of order, 25% on delivery and the

remaining 50%, on successful commissioning of the first Vortek Lamp, expected to be within 90 days of

delivery. When MesoCoat shall pay a 50% deposit on Vortek Lamps as aforesaid, Mattson will deliver

those Vortek lamps within six months after the deposit is paid, and will pay a penalty of 2% of the price

per week for every week’s delay after the end of such six-month period.

2.3

Volume Discounts. Initial Price List prices, and any subsequent Mattson Price List

prices for Vortek Lamps, shall be discounted by the percentage set forth in the following table for the

number of Vortek Lamps ordered, delivered and paid for by MesoCoat in any calendar year. These

discounts will only be granted to the extent that a MesoCoat purchase order for the number of Vortek

Lamps is issued and accepted, but will be adjusted upon acceptance of subsequent purchase orders for

delivery and payment in the same calendar year. By way of illustration and not limitation of the foregoing,

if MesoCoat’s first purchase order in a calendar year is for *** Vortek Lamps, they will be priced at a

volume discount of ***. If MesoCoat then issues a purchase order for *** more Vortek Lamps to be

delivered paid for in that same year, all *** Vortek Lamps will be sold to MesoCoat at a discount of ***,

with Mattson making appropriate adjustments in its invoice for the second order of Vortek Lamps.

THIS AGREEMENT AND THE TRANSACTIONS AND ACTIONS CONDUCTED HEREUNDER,

INCLUDING WITHOUT LIMITATION ANY APPLICABLE IMPLIED WARRANTIES OF

MERCHANTABILITY, FITNESS FOR PARTICULAR PURPOSE AND/OR NON-INFRINGEMENT.

5.2

LIMITATION ON LIABILITY. SUBJECT TO AND WITHOUT MITIGATION OF

THE PARTIES’ OBLIGATIONS UNDER SECTION 5.3, EXCEPT IN THE EVENT OF WILLFUL

Indemnification by Mattson. Except for those matters resulting from the willful

misconduct of MesoCoat, Mattson shall indemnify, defend and hold MesoCoat, its shareholders, officers,

directors, affiliates, agents, employees and their respective successors and assigns harmless from and

against any and all losses, claims, damages, liens, losses, or liabilities, costs, expenses, penalties,

assessments, and judgments (including reasonable attorneys’ fees and interest) (“Losses”) incurred in

connection with, arising out of, resulting from or incident to any claim that the Vortek Lamp infringes a

third party’s intellectual property rights; provided, however, that Mattson will have no obligation for

indemnification hereunder to the extent a claim is based upon the combination or use of any of the Vortek

Lamp with intellectual property developed solely or licensed by MesoCoat, if such infringement would

have been avoided in the absence of such combination or use.

5.4

Indemnification by MesoCoat. Except for those matters resulting from the willful

misconduct of Mattson, MesoCoat shall indemnify, defend and hold Mattson, its shareholders, officers,

directors, affiliates, agents, employees and their respective successors and assigns harmless from and

against any and all Losses incurred in connection with, arising out of, resulting from or incident to any

manufacturing equipment and other high-tech products and in particular without limitation owns patents,

trade secrets and other technology referred to as the Vortek™ plasma lamp (the “Vortek Lamp”).

MesoCoat intends to develop a high energy plasma arc lamp in a configuration suitable for heating

applied coatings and modifying surfaces developing this process capability using the Vortek Lamp, and to

market this capability (the “System”) to a variety of industrial uses requiring improved protection of

surfaces against wear and corrosion. MesoCoat intends to commit significant amounts of capital with

which to open up and develop the market for this System (the “Market”). The Market will be defined in

the Development Agreement.

Mattson intends to develop for MesoCoat and assembly using the Vortek Lamp that MesoCoat can

incorporate in the System, and to become a strategic supplier of Vortek Lamp technology to MesoCoat

and its customers.

Relationship of Parties

In return for the opportunity to participate in the Market which MesoCoat has committed significant

amounts of capital to develop, Mattson intends to grant MesoCoat exclusive rights to supply and use of

the Lamp incorporated in the System for the fields comprising the Market and at pricing levels that

recognize this relationship, as may be defined in the Development Agreement.

In order to maintain exclusivity, MesoCoat intends to invest/expend a minimum of $2M over 18 months

in the System and Market development. The Market fields are only intended to remain exclusive if and to

the extent that MesoCoat markets products in such field no later than two years after the effective date of

the Development Agreement on such field. MesoCoat’s exclusivity thereafter will be subject to its

accomplishing minimum sales goals for each field in the Market as may be defined in the Development

Agreement.

MesoCoat intends that the new configurations and/or improvements of the Vortek Lamp developed under

the Development Agreement be available for use by Mattson in areas other than the Market.

MesoCoat intends to reserve its rights in the Development Agreement to pursue other lamp technologies

and alternative solutions to the Vortek Lamp, as well as source outside suppliers for necessary support

equipment other than components of the System supplied by Mattson. If MesoCoat sources alternative

competitive technologies in place of the Vortek ▇▇▇ the MesoCoat’s rights may be terminated and would

in any event on longer be exclusive.

MesoCoat intends that Mattson be the sole supplier to MesoCoat and its customers of the Vortek Lamp

assembly and its component parts incorporated in the System. Unrelated third party suppliers have reverse

engineered or otherwise copied Mattson components and equipment and the parties intend that

Development Agreement will protect Mattson from such third party suppliers.
