[ * ] The original Section 4.2 of the Master Agreement shall be renumbered as Section 4.3, and a new Section 4.2 shall be added to the Master Agreement as follows: 4.2 For certain [ * ] purchases of [ * ] by R-R from TIMET, TIMET will [ * ]the [ * ] for such purchases by an [ * ], determined in accordance with the following provisions. (a) In the event R-R [ * ] from TIMET [ * ] of [ * ] and [ * ], TIMET will [ * ] the applicable [ * ] for such product(s) identified in the [ * ] by an amount (the [ * ]) determined by the formula described in Sections 4.2(b) through 4.2(d). (b) The [ * ] used to determine the [ * ] is the difference between: (i) the [ * ] of [ * ] plus [ * ] products purchased by R-R from TIMET in a [ * ] (rounded to the nearest [ * ]), and (ii) [ * ]. Provided, however, that the maximum [ * ] in any [ * ] shall be [ * ], subject to the limitations and qualifications contained in Section 2.12 of the Common Terms. (c) The [ * ] used to calculate the magnitude of the [ * ] applicable to R-R's [ * ] purchase of such [ * ] is [ * ] determined as follows. The maximum [ * ] in any [ * ] shall be limited to [ * ] per [ * ]. Because the maximum [ * ] per [ * ] is limited to [ * ], the [ * ] value for each [ * ] of [ * ] is [ * ]. (d) The [ * ] determined in accordance with Section 4.2(c) for each [ * ] is then multiplied by the [ * ]. The resulting product is the 2 percentage (the [ * ]) by which the price paid by R-R to TIMET in such [ * ] for all relevant products comprising the [ * ] will be [ * ]. The amount of this [ * ] (the [ * ]) will be [ * ]. (e) In the event the [ * ] of [ * ] and [ * ] together purchased by R-R from TIMET shall exceed [ * ] in any [ * ], the Parties agree to negotiate in good faith to determine the appropriate adjustments to be made to the [ * ] formula. The Parties acknowledge that an [ * ] TIMET production of [ * ] and [ * ] in excess of [ * ] may require an [ * ] of [ * ] by TIMET, and that TIMET will be entitled to [ * ] the [ * ] of such [ * ] that would have been [ * ] to be[ * ] to R-R under this provision had the [ * ] in that [ * ] not exceeded [ * ]. (f) TIMET will use its best efforts to account for and reconcile the [ * ] purchased during each [ * ] (either directly by R-R or indirectly by other Purchasers under the Master Agreement) by [ * ] of the [ * ] following.

For operations where TIMET identifies process capabilities of [ * ], TIMET and R-R shall cooperate to undertake immediate improvement plans with mutually agreed, targeted time-scales. For operations where TIMET identifies process capabilities of [ * ], TIMET and R-R shall cooperate to undertake proposals for [ * ] capability improvement in [ * ], added value to the process. The Parties shall work together to improve capabilities, in such of the above referenced areas in which they reach mutual agreement and cooperation as to improvements, by a [ * ] in the [ * ], after which time [ * ] improvement [ * ] shall be established as an ongoing function of the Customer Value Task Force. 4 (b) [ * ] for [ * ] Improvements. Specifically designated representatives of TIMET and of R-R, including representatives from [ * ] and any others to be designated by R-R, will work together in an effort to achieve targeted improvements in the [ * ] levels of [ * ]. The Parties will, through their meetings and discussions, mutually agree upon selected improvements that will ultimately be pursued. The Parties presently anticipate that the initial improvements will be targeted at the [ * ] in the [ * ] in the [ * ]. The Parties will initially [ * ] an improvement [ * ]. TIMET will contribute to the [ * ] improvements by a variety of possible means that may include, among other things, [ * ] refinement, modification to the [ * ] processing [ * ], and refinement to [ * ] cycles. Consistent with other confidentiality commitments that each of the Parties may have, the Parties agree to cooperate to the fullest possible extent in the exchange of information, knowledge and expertise (including both internally managed technology programmes and external research and development activities) in working toward these [ * ] improvements with respect to the following goals: (i) minimizing the [ * ] throughout the total manufacturing sequence from [ * ] to [ * ], (ii) achieving [ * ] improvements, and (iii) developing an enhanced understanding of [ * ] sequences. (c) [ * ] for [ * ]. TIMET will provide R-R with its best estimate of a datum point for the [ * ] scales for both [ * ] introduction and for [ * ] (specifically, from the [ * ] in TIMET's processing through delivery of [ * ] to R-R's nominated machinist) [ * ]. The Parties will work toward an [ * ] in each of these [ * ] over a [ * ] period, representing a [ * ] net, aggregate reduction of [ * ] in these [ * ] over such [ * ] period. The Parties understand and acknowledge that [ * ] in [ * ] for [ * ] necessarily involve commercial entities that are not party to this Master Agreement. Therefore, the Parties each agree to work with such other entities as are identified from time to time, in an effort to better facilitate achieving the [ * ], but acknowledge that such [ * ] cannot be [ * ]. TIMET further agrees to work toward providing the most rapid possible [ * ] given the existing circumstances to specific project activities and to short-notice changes required or requested by R-R, with a [ * ] of [ * ] an [ * ] level of TIMET [ * ] to R-R's [ * ]. The Parties agree to work together at all times to ensure that TIMET's [ * ] are harmonised with R-R's [ * ] and [ * ]. 5 (d) [ * ] for [ * ] Improvements. In the interests of [ * ] reduction through increased [ * ] utilisation, the Parties agree to cooperate in establishing a programme of work through which they will jointly develop one or more means directed at achieving a [ * ] of [ * ] improvement from the [ * ] stages of [ * ]. To this end, the Parties shall work together supporting and linking appropriate resources to achieve the following [ * ]: (i) to develop the consistent [ * ] of [ * ] that should optimally be specified for the safe manufacture of each [ * ], (ii) to develop proposals for the [ * ] with respect to both existing [ * ] and existing [ * ], and (iii) to develop fundamental and radical proposals for the achievement of [ * ] in [ * ]. The Parties agree to cooperate to work toward timely and cost-effective initiation of trial work that may be required prior to undertaking the steps necessary for testing and validation of proposed new initiatives. The Parties shall undertake such work in light of their due consideration for the [ * ] of [ * ] for safe [ * ] in the specified [ * ] environment. Where R-R and TIMET are jointly successful in [ * ] the [ * ] of [ * ], the amount of the [ * ] will be [ * ] by R-R and TIMET. (e) [ * ] Relating to Rolls-Royce Quality Renaissance. TIMET agrees to work together with R-R in implementing Rolls-Royce Quality Renaissance [ * ], with a [ * ] of achieving reductions in customer related incidents. In furtherance of these targets, the Parties shall each cooperate to: (i) Reduce by a [ * ] of one-half the rate of [ * ] during every [ * ] period. (ii) Work together to establish a mutual understanding of the appropriate methodology for defining [ * ] and an acceptable mechanism for evaluating and measuring [ * ] in the relevant contexts. Thereafter, the Parties agree to work together and each to use all commercially reasonable efforts toward the goal of reducing the [ * ], in both [ * ] and in [ * ], by a [ * ] factor of [ * ] during every [ * ] period. (iii)Reduce by a [ * ] of [ * ] the [ * ] of [ * ] and [ * ] during every [ * ] period. (f) [ * ] for Research and Development Activities. TIMET and R-R will each continue to [ * ] both internal and external research and development ("R&D") work at appropriate "Centres of Excellence" to include the appropriate [ * ], in order to work toward improving the Parties' understanding of the effects of [ * ] and [ * ] in [ * ] and [ * ], in the interests of [ * ]and [ * ]. Consistent with each Party's other confidentiality limitations and its necessity of protecting its proprietary technologies, and 6 providing that TIMET is not precluded from using the results of its R&D activities in manufacturing conducted outside the scope of any agreements with R-R, the Parties each agree, to the greatest extent possible, to make available to the other Party the results of such research and development work where such results could enhance the [ * ] and [ * ]. The Parties commit to undertake regular reviews of each of their R&D activities and to dedicate some portion of each of their total R&D activities in support of mutually agreed upon and mutually defined areas [ * ]. In addition to regular R&D activity reviews, the Parties commit to at least an [ * ] review of progress against the agreed upon R&D [ * ]. (g) Other [ * ] Initiatives. TIMET will use all commercially reasonable efforts to pursue such additional initiatives pertaining to [ * ] as have previously been or may in the future be discussed, and as are mutually agreed to by the Parties.

(i) Shared Understandings. The Parties will work together toward a [ * ] of achieving both shorter and longer term generic improvements to [ * ], and to this end will each continue to participate in Customer Value Initiatives and other regular forums to assist in achieving these [ * ]. The Parties commit to expanding the scope of the Customer Value Task Force as may be reasonably necessary to accomplish such exchanges. The Parties understand and acknowledge that all of the [ * ] and [ * ] identified in this Section 6.7 do not represent [ * ] for [ * ] of any specified [ * ], but, rather, represent their mutual [ * ]. The Parties further acknowledge that in the course of developing and implementing any new technical or production improvement [ * ], temporary [ * ] or [ * ] may inevitably result and, therefore, it may be necessary, from time to time, for the Parties to cooperate in agreeing upon such [ * ] as a part of the ultimate achievement of the [ * ]. 5.
