 General Terms of your
Stock Option. Your stock option gives you the right to purchase shares of common stock of Cabot at the per share exercise price, and subject to the vesting provisions, set forth above. This stock option is not intended to constitute an
incentive stock option pursuant to Section 422 of the Internal Revenue Code. 
 Vesting and Duration of your Stock Option. As
indicated in the table above, a portion of your award will vest, and becomes exercisable, on the [                    ] anniversaries of the
date of grant. Your stock option may become exercisable prior to the scheduled vesting dates under certain circumstances, such as a change in control, merger or other similar corporate transaction involving the Company, as explained in the
Prospectus for the 2009 Plan. After your stock option vests, it is generally exercisable, in whole or in part, at any time prior to its expiration date. Your stock option generally has a
            -year term. The conditions under which your award may expire before its scheduled expiration date, such as if your employment with Cabot ends, are explained below. In
addition, the exercise of your stock option may involve the sale of Cabot stock, and accordingly, there may be limitations on when you can exercise your stock option under Cabot’s Policy on Transactions in Securities, a copy of which is
being provided to you with the Prospectus for the 2009 Plan. 







 Circumstances that may lead to the termination of your stock option before the scheduled expiration date.
If your employment with Cabot ends and you continue to hold unexercised stock options, the following rules will apply: 
  

	 	•	 	 Any unvested options will be forfeited (unless your employment terminates because of your death or disability). 


  

	 	•	 	 Any vested stock options outstanding immediately prior to the cessation of your employment, to the extent exercisable, will remain exercisable for
three months after the date on which your employment ended or until the stated expiration date, if earlier. 


  

	 	•	 	 If your employment ceases because of your death or disability, any outstanding unvested stock options will become exercisable in full and all
outstanding stock options will remain exercisable for three years or until the stated expiration date, if earlier. 


  

	 	•	 	 If your employment ceases because of actions which cast such discredit on you as to justify immediate termination of your stock option, the
Administrator of the 2009 Plan has authority to terminate your stock option. 


 Exercising your Stock Option. You may
exercise your stock option by delivering to the Company a signed, written notice of exercise, in the form provided by Cabot, accompanied by payment of the exercise price for the number of shares of Cabot’s common stock for which you are
exercising your stock option, and any other payment required (such as applicable withholding taxes). If the completed notice of exercise and required payments are not delivered simultaneously, the exercise date will be the date that the last item is
received. We will deliver to you shares of Cabot common stock as soon as practicable following your proper exercise of your option. Any exercise must be for a minimum of 100 shares of Cabot stock (or the remaining total number of shares issuable
upon exercise of a particular stock option, if fewer). 
 Payment of the Exercise Price. You may pay for the shares you are purchasing
upon the exercise of your stock option in the following ways: 
  

	 	•	 	 your personal check, bank check or draft, a money order payable to the order of Cabot or by wire transfer of funds; 


  

	 	•	 	 a check, payable to the order of the Company from a brokerage firm handling the transaction on your behalf (a cashless exercise);



  

	 	•	 	 by delivery to the Company of shares of Cabot common stock held by you for at least six months having a market value (at the close of business on the
last business day preceding the date on which your completed and signed notice of exercise is sent or hand delivered to Cabot) equal in amount to the exercise price of the option being exercised, provided that (a) this method of payment is then
permitted by applicable law and (b) the shares used to pay the exercise price are not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirement (a stock swap); 


  

	 	•	 	 by any combination of the above permitted forms of payment.

 You may choose to exercise your stock option in a cashless exercise through a broker. A cashless exercise
involves a sale of Cabot stock in the market, with the proceeds applied to the stock option exercise price and any withholding taxes due, eliminating the use of your own funds. Because a cashless exercise involves the sale of Cabot stock in
the market, it must be completed in accordance with Cabot’s Policy on Transactions in Securities. Please review the restrictions on trading contained in the Policy before making arrangements for a cashless exercise. Please note that the
trading restrictions in Cabot’s Policy on Transactions in Securities do not apply to transactions with the Company, such as the exercise of a stock option with your own funds or the surrender of shares in payment of the exercise price or in
satisfaction of any tax withholding obligations, provided you do not sell the shares acquired while in possession of material nonpublic information or, if applicable to you, during a corporate blackout period. 
 Tax consequences of your Stock Option. The tax consequences of your stock option award are described in the Tax Information attached to this
award agreement. Employees in the U.S. must pay to Cabot any applicable withholding taxes due upon the exercise of their stock option at the time of exercise. The shares issuable upon exercise of your stock option will be valued for withholding tax
purposes at the closing price of Cabot’s common stock as reported on the New York Stock Exchange Composite Transactions on the exercise date. U.S. participants may pay these withholding taxes using the same methods of payment of the exercise
price. 
 No Employment Commitment; Rights as a Stockholder. The grant of this stock option does not confer any right to continued
employment or service with Cabot. Further, you have no rights as a stockholder with respect to the shares subject to this option until the proper exercise of the option and the issuance of the shares with respect to which the option has been
exercised. 
 Provisions of the 2009 Plan. The terms specified in this award agreement are governed by the terms of Cabot’s
2009 Long-Term Incentive Plan (the “2009 Plan”), a copy of which has been provided to you. Information about the 2009 Plan is also included in the Prospectus for the 2009 Plan, a copy of which has also been provided to you. The
Compensation Committee of Cabot’s Board of Directors has the exclusive authority to interpret this award and the 2009 Plan. Any interpretation of the award by the Committee and any decision made by it with respect to the award are final and
binding on all persons. To the extent that there is a conflict between the terms of this award agreement and the 2009 Plan, the 2009 Plan shall govern.

of any other jurisdiction.
