EXHIBIT 10.20
 TERMS OF INCENTIVE STOCK OPTION GRANTS
 1.
    
    Generally.This document sets forth the terms and conditions under which incentive stock
options (the ISO Options) are granted under paragraph 4(a) of the 2006 Long-Term Incentive
Plan (the Plan), which was approved by Ferro Corporation shareholders on November 3, 2006.
The ISO Option grants to which these terms apply are intended to qualify as incentive stock
options under Section 422 of the Internal Revenue Code of 1986, as amended. (The recipient of
an ISO Option grant is called the ISO Optionee below. The term Ferro below includes Ferro
Corporation and its subsidiary and affiliated companies.)2.
    
    Precedence of the Plan.The terms of this document are in all events subject to the terms
and conditions of the Plan. If there is any inconsistency between this document and the Plan,
then the Plan, and not this document, will govern. The Governance, Nomination and
Compensation Committee of the Board of Directors (or such other committee as the Board may
from time to time designate) (the Committee) administers awards under the Plan and has the
authority to determine the terms and conditions, not inconsistent with the provisions of the
Plan, of any Award granted under this Plan. In this capacity, the Committee also has the
authority to construe and interpret the provisions of the Plan and all awards under the Plan
and to establish, amend, and rescind rules and regulations for the administration of the Plan,
all of which will be binding on the ISO Optionee.3.
    
    Basic Option Terms.The name of the ISO Optionee, the date of the ISO Option grant, the
aggregate number of shares of Ferro Common Stock that may be purchased under the ISO Option,
the option exercise price, and the expiration date of the ISO Option (i.e., last date on which
such ISO Option may be exercised) are set forth separately in a grant letter from Ferro to the
ISO Optionee which refers expressly to this document.4.
    
    Normal Exercise.Except as otherwise provided below, ISO Options will become exercisable
only if and after the ISO Optionee has remained employed by Ferro for one year from the date
of the ISO Option grant, whereupon such rights shall become exercisable to the extent of 25%
of the aggregate number of shares granted, which percentage shall increase to 50% after two
years, 75% after three years and to 100% after four years of employment.5.
    
    Retirement.If an ISO Optionee retires from his or her employment with Ferro under a Ferro
retirement plan or policy (including early retirement) before an ISO Option has been exercised
or expired, then the ISO Option will become 100% exercisable when the ISO Optionee retires and
the ISO Optionee will then be entitled to exercise the ISO Option at any time on or before
such ISO Option expires.6.
    
    Disability.If an ISO Optionees employment terminates due to the ISO Optionees total and
permanent disability before an ISO Option has been exercised or expired, then the ISO Option
will become 100% exercisable when the ISO Optionees employment terminates and the ISO
Optionee will then be entitled to exercise the ISO Option at any time on or before such ISO
Option expires.7.
    
    Death.If an ISO Optionee dies before an ISO Option has been exercised or expired, then the
person who is entitled by will or the applicable laws of descent and distribution may exercise
the option rights (a) in full in the case of an ISO Optionee who was employed by Ferro at the
time of his or her death or (b) in the case of an ISO Optionee not so employed, to the extent
that the ISO Optionee was entitled to exercise the same immediately before his or her death.8.
    
    Change of Control.If a Change of Control occurs before an ISO Option has been exercised
or expired, then the ISO Option will become 100% exercisable immediately upon the Change of
Control provided thatthe ISO Optionee is then employed by Ferro. (For purposes of this
document, the term Change of Control has the meaning given to that term in paragraph 9 of
the Plan.)

    Other Termination of Employment.If the ISO Optionees employment with Ferro terminates
before an ISO Option has been exercised or expired for any reason other than those stated in
clauses 5-8 above, the ISO Optionee may exercise the option rights at any time within the
three-month period after his or her termination of employment (but before the expiration of
the ISO Option) to the extent he or she was entitled to exercise the same immediately before
the termination of employment.10.
    
    Liquidation, Dissolution and Merger.If at any time before an ISO Option is exercised or
expires Ferro is liquidated or dissolved, or becomes a party to a plan of merger or
consolidation with respect to which Ferro is not the surviving corporation, then the following
will apply:
 A.
    
    Ferro will give the ISO Optionee at least 30 days prior written notice that
such event will occur.B.
    
    If the ISO Optionee is then employed by Ferro, then the ISO Option will
immediately become 100% exercisable provided thatthe ISO Optionee exercises the ISO
Option before it expires and within 30 days after the notice.C.
    
    If the ISO Optionee is not then employed by Ferro, then the ISO Option will be
exercisable to the extent it was exercisable on the date of such notice provided that
the ISO Optionee exercises the ISO Option before it expires and within 30 days after
the notice.
  11.
    
    Exercise.An ISO Option may be exercised by delivering to Ferro at the office of its
Treasurer a written notice signed by the person entitled to exercise the option, of the
election to exercise the option and stating the number of shares to be purchased, together
will full payment of the option exercise price of the shares then to be purchased. Payment of
the option exercise price may be made, at the election of the ISO Optionee, (a) in cash, (b)
in Ferro Common Stock, or (c) in any combination of cash and Ferro Common Stock. Shares of
Ferro Common Stock used in payment of the purchase price will be valued at their closing price
on the New York Stock Exchange on the trading day immediately preceding the date of exercise.
Upon the proper exercise of an ISO Option, Ferro will issue the appropriate number of shares
of Ferro Common Stock in the name of the person exercising the ISO Option and deliver to him
or her a certificate or certificates for the shares purchased. The ISO Optionee will either
pay in cash, within the time period specified by Ferro, the amount (if any) required to be
withheld for Federal, state or local tax purposes on account of the exercise of an ISO Option
or to make arrangements to satisfy such withholding requirements in a manner satisfactory to
Ferro.12.
    
    Legal Restrictions on Exercise.No ISO Option will be exercisable if and to the extent such
exercise would violate:
 A.
    
    Any applicable state securities law;B.
    
    Any applicable registration or other requirements under the Securities Act of
1933, as amended (the 1933 Act) the Securities Exchange Act of 1934, as amended, or
the listing requirements of any stock exchange; orC.
    
    Any applicable legal requirement of any other government authority.
