1.6     Payment
for Inventory.

(a) Nano is purchasing the inventory described in Schedule A-1 (the Purchased Inventory)
for $2,014,000, subject to adjustment after Closing pursuant to Section 1.6(c)
hereof (the Purchased Inventory
Purchase Price). Nano shall pay for the Purchased Inventory in
the manner described in this Section. Within ten (10) days after the end of the
month in which Nano receives payment on the sale by Nano of each Automated
Interferometer System that includes Purchased Inventory, Nano shall pay to Zygo
an amount equal to the price paid to Nano by Nanos customer for such entire
system (adding back the dollar amount of any set-offs or other types of
credits, or reductions to the purchase price actually applied, for amounts Nano
may otherwise owe to such customer) but reducing such by the cost of the Head
included in the Automated Interferometer System (which will be paid for in
accordance with the Supply Agreement), to be applied toward the Purchased
Inventory Purchase Price, until the total Purchased Inventory Purchase Price
has been paid in full, and thereafter to the Demo Equipment Purchase Price (as
defined below) until such amount has been paid in full. For example, if Nano
sells an Automated Interferometer System for $1,200,000 that includes any
Purchased Inventory, and the outstanding balance of the Purchased Inventory
Purchase Price exceeds $1,200,000 at the time of such sale, then Nano shall pay
to Zygo the amount of $1,200,000 less the cost of the Head included in such
System (which will be paid for in accordance with the Supply Agreement) within
ten (10) days after the end of the month in which Nano receives payment from
Nanos customer, and such amount shall be applied toward the outstanding
balance of the Purchased Inventory Purchase Price.

(b) Nano hereby agrees that, from and after the Closing Date until such time as
the Purchased Inventory Purchase Price and the Demo Equipment Purchase Price
have been paid in full (or, in the case of subsection (b)(v) below, until 30
days following the calendar quarter during which the last of such outstanding
amounts shall have been paid in full):

(i)
in the production of any Automated Interferometer System, Nano shall first
utilize the Purchased Inventory prior to utilizing alternatively available
inventory

(ii) Nano shall not use Purchased Inventory for any purpose other than the
production of such systems or in connection with providing warranty service or
other service with respect to Automated Interferometer Systems sold by Zygo or by
Nano;

(iii) Nano shall sell the Automated Interferometer System for cash consideration
(including a check or money order) and shall set pricing based on its standard
practices for ordinary course arms-length third party transactions (Standard
Prices);

(iv) Nano shall make diligent efforts, consistent with its historical practice,
to collect payment for all sales of its Automated Interferometer Systems as to
which all or any portion of such payment shall be paid to Zygo pursuant to the
provisions of Sections 1.6 and/or 1.7 hereof; and

- 4 -

---



(v) No later than 30 days following each calendar quarter, Nano will provide
Zygo with a statement of its sales of Automated Interferometer Systems,
certified by Nanos Chief Financial Officer. Upon reasonable notice, and at
Zygos cost and expense, Nano will permit Zygo and its representatives to audit
Nanos books and records as they pertain to sales of Automated Interferometer
Systems; provided that if an audit reveals discrepancy of greater than the
lesser of (x) $50,000 or (y) five (5) times aggregate dollar sales, then the
cost and expense of such audit shall be borne by Nano.

(c) No later than fifteen (15) business days after the Closing Date, Zygo shall
perform a physical inventory on the Purchased Inventory in accordance with
generally accepted accounting principles applied consistently with Zygos past
practices. Nano, or their respective representatives, shall observe the taking
of the inventory at its sole cost and expense. Disputes between Zygo and Nano
with respect to the merchandise inventory shall be resolved by Zygo and Nano at
the time the physical inventory is being taken. The results of the inventory
shall conclusively be deemed to be the Purchased Inventory for purposes of this
Agreement. As part of this inventory, Zygo shall determine the book value of
the Purchased Inventory as of the Closing Date, in accordance with generally
accepted accounting principles applied consistently with Zygos past practices.
The determination of the book value of the Purchased Inventory as of the
Closing Date pursuant to this Section 1.6(c), shall, for all purposes of this
Agreement, be the Purchased Inventory Purchase Price. All work sheets used in
determining the foregoing shall be signed by Zygo and Nano or their respective
representatives.

1.7
Payment for Demo Equipment. Nano is purchasing the Demo equipment
described inSchedule A-1 (the Demo Equipment) for $1,583,224.66, which the
parties hereby agree is the net book value (NBV) thereof as of the Closing Date
(the Demo Equipment
Purchase Price). Nano shall pay for such equipment in the
manner described in this Section. After the outstanding balance of the
Purchased Inventory Purchase Price shall have been reduced to zero pursuant to
Section 1.6 of this Agreement, then within ten (10) days after the end of
the month in which Nano receives payment on the sale by Nano of each Automated
Interferometer System, Nano shall pay to Zygo an amount equal to the price paid
to Nano by Nanos customer for such system, to be applied toward the price of
the Demo Equipment, until the Demo Equipment Purchase Price shall have been
paid in full. For example, if, after the Purchased Inventory Purchase Price
shall have been reduced to zero pursuant to Section 1.6 of this Agreement,
Nano sells an Automated Interferometer System for $1,200,000 and the
outstanding balance of the Demo Equipment Purchase Price exceeds $1,200,000 at
the time of such sale, then Nano shall pay to Zygo the amount of $1,200,000
within ten (10) days after the end of the month in which Nano receives payment
of $1,200,000 from Nanos customer, and such $1,200,000 shall be applied toward
the outstanding balance of the Demo Equipment Purchase Price.

1.8
Acceleration. Notwithstanding the provisions of Section 1.6 and 1.7
to the contrary, if, prior to the date on which Nano shall have paid to Zygo in
full the outstanding

- 5 -

balance of the
Purchased Inventory Purchase Price and the Demo Equipment Purchase Price, [*].

1.9
Full Payment of Acquired Assets. Notwithstanding the provisions of
Sections 1.6 and 1.7 above or any other provision of this Agreement, full payment
by Nano to Zygo for the Purchased Inventory Purchase Price and Demo Equipment
Purchase Price shall be completed (paid in full) no later than ten (10)
business days after the first anniversary of the Closing.

within 20 days after receipt by the Indemnified Party of notice of such Third
Party Action, and shall describe in reasonable detail (to the extent known by

assume control
of the defense of such Third Party Action with counsel reasonably satisfactory
to the Indemnified Party; provided that the Indemnifying Party may not assume
control of the defense of Third Party Action involving criminal liability or in
which equitable relief is sought against the Indemnified Party. If the

summons, complaint or other pleading which may have been served on such party and
any written claim, demand, invoice, billing or other document evidencing or

respect to such Third Party Action. The Indemnifying Party shall not agree to
any settlement of, or the entry of any judgment arising from, any Third Party
Action without the prior written consent of the Indemnified Party, which shall
not be unreasonably withheld, conditioned or delayed. The Indemnified Party
shall not agree to any settlement of, or the entry of any judgment arising
from, any such Third Party Action without the prior written consent of the
Indemnifying Party, which shall not be unreasonably withheld, conditioned or
delayed.

In connection with any arbitration proceeding pursuant to this Agreement, each
party shall bear its own costs and expenses, except that the fees and costs of
the AAA and

- 15 -

the
Arbitrator, the costs and expenses of obtaining the facility where the
arbitration hearing is held, and such other costs and expenses as the
Arbitrator may determine to be directly related to the conduct of the
arbitration and appropriately borne jointly by the parties (which shall not
include any partys attorneys fees or costs, witness fees (if any), costs of
investigation and similar expenses) shall be shared equally by the Indemnified
Party and the Indemnifying Party.

5.5
Survival of Representations and Warranties. All representations and
warranties that are covered by the indemnification agreements in Section 5.1(a)
and Section 5.2(a) shall (a) survive the Closing and (b) shall expire on the
date 18 months following the Closing Date, except that the representations and
warranties set forth in Sections 2.1, 2.2, 3.1 and 3.2 shall survive the
Closing. If an Indemnified Party delivers to an Indemnifying Party, before
expiration of a representation or warranty, either a Claim Notice based upon a
breach of such representation or warranty, or an Expected Claim Notice based
upon a breach of such representation or warranty, then the applicable
representation or warranty shall survive until, but only for purposes of, the
resolution of the matter covered by such notice. If the legal proceeding or
written claim with respect to which an Expected Claim Notice has been given is
definitively withdrawn or resolved in favor of the Indemnified Party, the
Indemnified Party shall promptly so notify the Indemnifying Party. The rights
to indemnification set forth in this Article V shall not be affected by (x) any
investigation conducted by or on behalf of an Indemnified Party or any
knowledge acquired (or capable of being acquired) by an Indemnified Party,
whether before or after the Closing Date, with respect to the inaccuracy or
noncompliance with any representation, warranty, covenant or obligation which
is the subject of indemnification hereunder or (y) any waiver by an Indemnified
Party of any closing condition relating to the accuracy of any representations
and warranties or the performance of or compliance with agreements and
covenants.

which it would otherwise be liable under this Article V exceed [*]. Thereafter Zygo will be

contrary contained in this Agreement, in no event shall Zygo be liable for any
consequential, indirect, punitive, individual or special damages of any nature,
or any damage or claim for lost profits.

5.7
Treatment of Indemnity Payments. Any payments made to an Indemnified
Party pursuant to this Article V shall be treated as an adjustment to the
consideration paid hereunder for tax purposes.
