earliest to occur of the following dates:
 a.
    
    Term of SAR. The SAR terminates eight (8) years from the Date of Grant, or upon
the liquidation of the Company, if earlier. If you have not fully exercised the SAR prior to

the SAR. The SAR will also expire and be forfeited at such times and in such circumstances
as otherwise provided in this Certificate or under the Plan.
 b.
    
    Termination on Death. If you incur a Termination of Service (as defined in the
Plan) on account of your death, or if you die within ninety (90) days after you cease to be
so employed on account of a termination identified in Paragraph 2(f), the vested portion of
the SAR shall terminate unless exercised within the earlier of: (i) the three (3) year period
after you incur such Termination of Service, or (ii) the term of the SAR. Any unvested
portion of the SAR will terminate and be forfeited on the date you incur the Termination of

SAR will terminate and be forfeited on the date in which you incur the Termination of
Service.

    Termination on Retirement. If you incur a Termination of Service on account of
your Retirement (as defined in the Plan), any vested portion of the SAR shall terminate
unless exercised within the earlier of (i) the three (3) year period after you incur such
Termination of Service, or (ii) the term of the SAR. Any unvested portion of the SAR will
terminate and be forfeited on the date in which you incur the Termination of Service.
 e.
    
    Termination for Cause. If you incur a Termination Service on account of a
termination for Cause (as defined in the Plan), the SAR will immediately terminate on the
date of such Termination of Service and you will forfeit all Shares underlying any exercised
portion of the SAR for which the Company has not delivered certificates, and the Company
shall refund to you the price equal to the lesser of (i) the Exercise Price Per Share you
paid for such Shares or (ii) the Fair Market Value (as defined in the Plan) of the Shares on
the date of such Termination of Service.
 f.
    
    Termination for Any Other Reason. If you incur a Termination of Service for any
reason other than as identified in this Paragraph 2, any vested portion of the SAR shall
terminate unless exercised by you or a transferee under Paragraph 6, if applicable, within

term of the SAR. Any unvested portion of the SAR will terminate and be forfeited on the date
you incur the Termination of Service.
 3.
    
    Exercising the SAR; Payment Upon Exercise.
 a.
    
    Notice. When you want to exercise any portion of the SAR, you must give written
notice to ICG, or its designee, of your intent to exercise the SAR and specify the number of
Shares as to which the SAR is to be exercised.
 b.
    
    Payment with Respect to the SAR. Upon exercise, ICG shall deliver to you a number
of shares of ICG common stock (the Common Stock) that will be determined by dividing the
Value of the Stock Appreciation (as defined below), by the Fair Market Value of a share of
Common Stock on the date of exercise. Only whole shares of Common Stock will be delivered to
you pursuant to the exercise of the SAR, and, to the extent that a fractional share of Common
Stock would result, the cash value of such fractional share will be paid to you in lieu of a
fractional share. All shares of Common Stock will be issued under the Plan. For purposes of
this Paragraph 3(b), the Value of the Stock Appreciation shall mean the amount that results
from multiplying (i) the number of Shares as to which the SAR is to be exercised, by (ii) the
difference between the Fair Market Value of a Share on the date of exercise and the Base
Amount.
 c.
    
    Cancellation of Shares. Upon exercise of the SAR, the Shares covered by such
exercise shall be cancelled and you shall cease to have any further right to exercise the SAR
with respect to such Shares under this Certificate.
 d.
    
    Limitation on Exercise. This SAR may not be exercised when the Base Amount is
equal to, or greater than, the Fair Market Value of a Share.
 e.
    
    The obligation of ICG to deliver shares of Common Stock upon exercise of the SAR shall be
subject to all applicable laws, rules and regulations and such approvals by governmental
agencies as may be deemed appropriate by the Committee, including such actions as ICGs
counsel shall deem necessary or appropriate to comply with relevant securities laws and
regulations. You understand that you are responsible for the income tax consequences of your
exercise of the SAR and the sale of any shares of Common Stock received by you upon exercise
of the SAR. ICG may require that you (or the person exercising the SAR pursuant to a
transfer in accordance with Paragraph 5 below) represent that any shares of Common Stock that
you receive will be held by you for your own account and not with a view to or for sale in
connection with any distribution of the shares, or such other representation as the Committee
deems appropriate. All obligations of ICG under this Certificate shall be subject to the
rights of ICG as set forth in the Plan to withhold amounts required to be withheld for any
taxes, if applicable. Subject to Committee approval, you may elect to satisfy any tax
withholding obligation of the Company with respect to the SAR by having shares of Common
Stock that you receive upon exercise of the SAR withheld up to an amount that does not exceed
the minimum applicable withholding tax rate for federal (including FICA), state and local tax
liabilities.
 4
    
    Change of Control. The provisions of the Plan applicable to a Change of Control (as
defined in the Plan) shall apply to the SAR, and, in the event of a Change of Control, the
Committee may take such actions as it deems appropriate pursuant to the Plan.
 5.
    
    Transferability of the SAR. Only you may exercise the SAR during your lifetime.
After your death, the SAR shall be exercisable (subject to the limitations specified in the
Plan) solely by your legal representatives, or by the person who acquires the right to
exercise the SAR by will or by the laws of descent and distribution, to the extent that the
SAR is exercisable pursuant to this Certificate.

event of the levy of any attachment, execution or similar process upon the rights or interests
hereby conferred, ICG may terminate the SAR by notice to you, and the SAR and all rights

amended or modified except by a written agreement executed by you, or your legal
representative, as applicable, and by ICG, or by its successors or legal representative, as

    The failure of you or ICG to insist upon strict compliance with any provision of this
Certificate or the Plan, or to assert any right that you or ICG, respectively, may have under
this Certificate or the Plan, shall not be deemed to be a waiver of such provision or right
or any other provision or right of this Certificate or the Plan.
 e.
    
    Nothing in this Certificate shall confer on you the right to continue in the employment or
service of the Company, its parent or subsidiaries, or interfere in any way with the right of
the Company, its parent or subsidiaries, and its stockholders to terminate your employment or
service at any time.
 f.
    
    Notwithstanding anything in this Agreement to the contrary, to the extent that this SAR is
deemed to be deferred compensation subject to the requirements of section 409A of the Code,
and the requirements of section 409A of the Code are not met with respect to this SAR, ICG
may amend this Certificate, without your consent, so that this SAR will comply with the
requirements of section 409A of the Code. Amendment of this Certificate to comply with
section 409A of the Code will not result in you being entitled to receive any enhanced
