WHEREAS, Novolyte and Ferro entered into that certain Asset Purchase Agreement
dated September 29, 2008 (the “Purchase Agreement”).

WHEREAS, Novolyte and Ferro now desire to amend the Purchase Agreement as set
forth herein.

NOW, THEREFORE, Novolyte and Ferro hereby agree as follows:

1. Definitions. Except as otherwise defined herein, all capitalized terms used
herein shall have the meanings ascribed to them in the Purchase Agreement.

2. Amendment to Section 2.6. Section 2.6 of the Purchase Agreement is hereby
amended by deleting such Section in its entirety and substituting in lieu
thereof the following:

“2.6 Purchase Price. For purposes of this Purchase Agreement, the term “Purchase
Price” means –

(A) Fifty Two Million Dollars ($52,000,000) (the “Closing Purchase Price”), plus

(B) Eight Million Dollars ($8,000,000) (the “Suzhou Equity Interest Purchase
Price”), representing the purchase price for the Suzhou Equity Interest, plus or
minus

(C) The amount of the adjustment determined in accordance with Section 2.7 (the
“Adjustment”).

3. Amendment to Section 5.2. The third sentence of Section 5.2 of the Purchase
Agreement is hereby amended by deleting such sentence and substituting in lieu
thereof the following:

“Except with regards to the Suzhou Equity Interest, the transfer of which is
governed by the Suzhou Equity Interest Transfer Agreement, title to the Acquired
Assets will be deemed to have transferred as of Closing, and revenues, expenses
and other pro-ratable items will be deemed to have been transferred as of
11:59 p.m. on the Closing Date (the “Closing Time”). Closing Working Capital
shall be determined as of the Closing Time but without giving effect to the
transactions consummated at the Closing.”

4. Amendment to Section 6.5(B). Section 6.5(B) of the Purchase Agreement is
hereby amended by deleting such Section in its entirety and substituting in lieu
thereof the following:

(B) Additional Agreements if Suzhou Equity Transfer Is Not Consummated. If the
Suzhou Equity Transfer is not consummated pursuant to the terms of the Suzhou
Equity Transfer Agreement, on or prior to June 30, 2009, then Ferro shall
continue to operate the Suzhou business for the benefit of Novolyte pursuant to
the terms of the Management and Transition Services Agreement and at such time
as shall be mutually determined by Novolyte and Ferro, Ferro shall sell,
transfer and convey to Novolyte or its assignee all of the Tangible Personal
Property located at the Suzhou Location on an AS-IS basis (the “Suzhou Personal
Property”) for a price equal to $8 million (the “Suzhou Personal Property
Price”) minus the aggregate cost to Novolyte of (1) transporting the Suzhou
Personal Property to a location determined by Novolyte, and (2) purchasing or
establishing an operational business at such location having the same production
capabilities as the Suzhou business (items (1) and (2) hereof are collectively,
the “New Establishment Costs”); provided, however, in no event will the amount
paid to Ferro be less than $3.5 million and provided further, that the parties
shall cause such funds to be released from the Escrow Agent on or before
December 31, 2009. For the avoidance of doubt, Ferro may not (a) sell the Suzhou
Personal Property to any third party, or (b) use the Suzhou Personal Property
for any purpose other than pursuant to this Section 6.5(B), and Ferro Suzhou
shall remain subject to the provisions of Section 6.5(A). For the avoidance of
doubt, if the Suzhou Equity Closing has not occurred by June 30, 2009 and has
not otherwise been extended pursuant to the terms of the Suzhou Equity Transfer
Agreement, Novolyte shall be entitled to receive $4.5 million out of the Escrow
Funds on June 30, 2009 and Ferro shall be entitled to receive $3.5 million out
of the Escrow Funds by December 31, 2009.

5. Conditions to Novolyte’s Obligations. Novolyte agrees that all conditions to
Novolyte’s obligations to consummate the transactions consummated by the
Purchase Agreement have been satisfied or waived, including the requirement that
Ferro obtain lien releases related to certain IBM computers; provided that
nothing herein shall relieve Ferro or Novolyte from responsibility pursuant to
the terms of the Purchase Agreement or Other Agreement for any breach of any
representation or warranty contained in the Purchase Agreement or any Other
Agreement.

6. Filing of Lien Releases. Novolyte agrees that as long as Ferro instructs its
agents to file the releases of liens related to the Acquired Assets on the
Closing Date that any delay in such filings shall not be any basis for a breach
by Ferro of the Purchase Agreement.

7. Effect. Except as specifically set forth herein, the Purchase Agreement shall
continue in full force and effect.

8. Counterparts. This First Amendment may be executed and delivered by Novolyte
and Ferro in separate counterparts, with the same effect as though all such
parties had executed and delivered the same copy hereof.

9. Governing Law. This First Amendment shall be governed by, and construed in
accordance with, the internal laws, and not the law of conflicts, of the State
of Ohio.
