In addition, the member of the Grace Group retaining such Delayed GCP Asset or such Delayed GCP Liability shall, insofar as reasonably possible and to the extent permitted by applicable Law, treat such Delayed GCP Asset or Delayed GCP Liability in the ordinary course of business in accordance with past practice and take such other actions as may be reasonably requested by the member of the GCP Group to which such Delayed GCP Asset is to be transferred or assigned, or which will assume such Delayed GCP Liability, as the case may be, in order to place such member of the GCP Group in a substantially similar position as if such Delayed GCP Asset or Delayed GCP Liability had been transferred, assigned or assumed as contemplated hereby and so that all the benefits and burdens relating to such Delayed GCP Asset or Delayed GCP Liability, as the case may be, including use, risk of loss, potential for gain, and dominion, control and command over such Delayed GCP Asset or Delayed GCP Liability, as the case may be, and all costs and expenses related thereto, shall inure from and after the Effective Time to the GCP Group.

(d)    Transfer of Delayed GCP Assets and Delayed GCP Liabilities. If and when the Approval or Notification, the absence of which caused the deferral of transfer or assignment of any Delayed GCP Asset or the deferral of assumption of any Delayed GCP Liability pursuant to Section 2.4(b), is obtained or made, and, if and when any other legal impediments for the transfer or assignment of any Delayed GCP Asset or the assumption of any Delayed GCP Liability have been removed, the transfer or assignment of the applicable Delayed GCP Asset or the assumption of the applicable Delayed GCP Liability, as the case may be, shall be effected in accordance with the terms of this Agreement, the Restructuring Steps Memorandum and/or the applicable Ancillary Agreement.

(e)    Costs for Delayed GCP Assets and Delayed GCP Liabilities. Any member of the Grace Group retaining a Delayed GCP Asset or Delayed GCP Liability due to the deferral of the transfer or assignment of such Delayed GCP Asset or the deferral of the assumption of such Delayed GCP Liability, as the case may be, shall not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced (or otherwise made available) by GCP or the member of the GCP Group entitled to the Delayed GCP Asset or Delayed GCP Liability, other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by GCP or the member of the GCP Group entitled to such Delayed GCP Asset or Delayed GCP Liability.

(f)    Approvals and Notifications for Grace Assets. To the extent that the transfer or assignment of any Grace Asset or the assumption of any Grace Liability requires any Approvals or Notifications, the Parties shall use their commercially reasonable efforts to obtain or make such Approvals or Notifications as soon as reasonably practicable; provided, however, that, except to the extent expressly provided in this Agreement or any of the Ancillary Agreements or as otherwise agreed between Grace and GCP, neither Grace nor GCP shall be obligated to contribute capital or pay any consideration in any form (including providing any letter of credit, guaranty or other financial accommodation) to any Person in order to obtain or make such Approvals or Notifications.

(g)    Delayed Grace Transfers. If and to the extent that the valid, complete and perfected transfer or assignment to the Grace Group of any Grace Asset or assumption by the Grace Group of any Grace Liability would be a violation of applicable Law or require any Approval or Notifications in connection with the Separation or the Distribution that has not been obtained or made by the Effective Time then, unless the Parties mutually shall otherwise determine, the transfer or assignment to the Grace Group of such Grace Assets or the assumption by the Grace Group of such Grace Liabilities, as the case may be, shall be automatically deemed deferred and any such purported transfer, assignment or assumption shall be null and void until such time as all legal impediments are removed or such Approval or Notification has been obtained or made. Notwithstanding the foregoing, any such Grace Assets or Grace Liabilities shall continue to constitute Grace Assets and Grace Liabilities for all other purposes of this Agreement.

(h)    Treatment of Delayed Grace Assets and Delayed Grace Liabilities. If any transfer or assignment of any Grace Asset or any assumption of any Grace Liability intended to be transferred, assigned or assumed hereunder, as the case may be, is not consummated on or prior to the Effective Time whether as a result of the provisions of Section 2.4(g) or for any other reason (any such Grace Asset, a “Delayed Grace Asset” and any such Grace Liability, a “Delayed Grace Liability”), then, insofar as reasonably possible and subject to applicable Law, the member of the GCP Group retaining such Delayed Grace Asset or such Delayed Grace Liability, as the case may be, shall thereafter hold such Delayed Grace Asset or Delayed Grace Liability, as the case may be, for the use and benefit of the member of the Grace Group entitled thereto (at the expense of the member of the Grace Group entitled thereto). In addition, the member of the GCP Group retaining such Delayed Grace Asset or such Delayed Grace Liability shall, insofar as reasonably possible and to the extent permitted by applicable Law, treat such Delayed Grace Asset or Delayed Grace Liability in the ordinary course of business in accordance with past practice and shall take such other actions as may be reasonably requested by the member of the Grace Group to which such Delayed Grace Asset is to be transferred or assigned, or which will assume such Delayed Grace Liability, as the case may be, in order to place such member of the Grace Group in a substantially similar position as if such Delayed Grace Asset or Delayed Grace Liability had been transferred, assigned or assumed as contemplated hereby and so that all the benefits and burdens relating to such Delayed Grace Asset or Delayed Grace Liability, as the case may be, including use, risk of loss, potential for gain, and dominion, control and command over such Delayed GCP Asset or Delayed GCP Liability, as the case may be, and all costs and expenses related thereto, shall inure from and after the Effective Time to the Grace Group.

(i)    Transfer of Delayed Grace Assets and Delayed Grace Liabilities. If and when the Approval or Notification, the absence of which caused the deferral of transfer or assignment of any Delayed Grace Asset or the deferral of assumption of any Delayed Grace Liability, is obtained or made, and, if and when any other legal impediments for the transfer or assignment of any Delayed Grace Asset or the assumption of any Delayed Grace Liability have been removed, the transfer or assignment of the applicable Delayed Grace Asset or the assumption of the applicable Delayed Grace Liability, as the case may be, shall be effected in accordance with the terms of this Agreement, the Restructuring Steps Memorandum, and/or the applicable Ancillary Agreement.

(j)    Costs for Delayed Grace Assets and Delayed Grace Liabilities. Any member of the GCP Group retaining an Delayed Grace Asset or Delayed Grace Liability due to the deferral of the transfer or assignment of such Delayed Grace Asset or the deferral of the assumption of such Delayed Grace Liability, as the case may be, shall not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced (or otherwise made available) by Grace or the member of the Grace Group entitled to the Delayed Grace Asset or Delayed Grace Liability, other than reasonable out-of-pocket expenses, attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by Grace or the member of the Grace Group entitled to such Delayed Grace Asset or Delayed Grace Liability.

2.6    Release of Guarantees. In furtherance of, and not in limitation of, the obligations set forth in Section 2.5:

(a)    On or prior to the Effective Time or as soon as practicable thereafter, each of Grace and GCP shall, at the request of the other Party and with the reasonable cooperation of such other Party and the applicable member(s) of such other Party’s Group, use commercially reasonable efforts to (i) have any member(s) of the Grace Group removed as guarantor of or obligor for any GCP Liability to the extent that they relate to GCP Liabilities, including the removal of any Security Interest on or in any Grace Asset that may serve as collateral or security for any such GCP Liability, and (ii) have any member(s) of the GCP Group removed as guarantor of or obligor for any Grace Liability to the extent that they relate to Grace Liabilities, including the removal of any Security Interest on or in any GCP Asset that may serve as collateral or security for any such Grace Liability.

(i)    any member of the Grace Group, GCP shall execute a guarantee agreement in the form of the existing guarantee or such other form as is agreed by the relevant parties to such guarantee agreement, which agreement shall include the removal of any Security Interest on or in any Grace Asset that may serve as collateral or security for any such Grace Liability, except to the extent that such existing guarantee contains representations, covenants or other terms or provisions either (i) with which GCP would be reasonably unable to comply or (ii) which GCP would not reasonably be able to avoid breaching; and

(ii)    any member of the GCP Group, Grace shall execute a guarantee agreement in the form of the existing guarantee or such other form as is agreed by the relevant parties to such guarantee agreement, which agreement shall include the removal of any Security Interest on or in any GCP Asset that may serve as collateral or security for any such GCP Liability, except to the extent that such existing guarantee contains representations, covenants or other terms or provisions either (i) with which Grace would be reasonably unable to comply or (ii) which Grace would not reasonably be able to avoid breaching.

2.7    Termination of Agreements.

(a)    Except as set forth in Section 2.7(b), in furtherance of the releases and other provisions of Section 4.1, GCP, on its own behalf and each member of the GCP Group, on the one hand, and Grace, on its own behalf and each member of the Grace Group, on the other hand, hereby terminate any and all agreements, arrangements, commitments or understandings, whether or not in writing, between or among GCP and/or any member of the GCP Group, on the one hand, and Grace and/or any member of the Grace Group, on the other hand, effective as of the Effective Time. No such terminated agreement, arrangement, commitment or understanding (including any provision thereof which purports to survive termination) shall be of any further force or effect after the Effective Time. Each Party shall, at the reasonable request of the other Party, take, or cause to be taken, such other actions as may be necessary to effect the foregoing.

(b)    The provisions of Section 2.7(a) shall not apply to any of the following agreements, arrangements, commitments or understandings (or to any of the provisions thereof): (i) this Agreement and the Ancillary Agreements (and each other agreement or instrument expressly contemplated by this Agreement or any Ancillary Agreement to be entered into by any of the Parties or any of the members of their respective Groups or to be continued from and after the Effective Time), (ii) any agreements, arrangements, commitments or understandings listed or described on Schedule 2.7(b)(ii), (iii) any agreements, arrangements, commitments or understandings to which any Third Party is a party, including any Shared Contracts, (iv) any intercompany accounts payable or accounts receivable accrued as of the Effective Time that are reflected in the books and records of the Parties or otherwise documented in writing in accordance with past practices, which shall be settled in the manner contemplated by Section 2.7(c), and (v) any agreements, arrangements, commitments or understandings to which any non-wholly owned Subsidiary of Grace or GCP, as the case may be, is a party (it being understood that directors’ qualifying shares or similar interests will be disregarded for purposes of determining whether a Subsidiary is wholly owned).

(c)    All of the intercompany accounts receivable and accounts payable between any member of the Grace Group, on the one hand, and any member of the GCP Group, on the other hand, outstanding prior to the effective time of the Internal Distribution or the Effective Time, respectively, shall, prior to the effective time of the Internal Distribution or the Effective Time, respectively, be repaid, settled or otherwise eliminated by means of cash payments, a dividend, capital contribution, a combination of the foregoing, or otherwise as determined by Grace in its sole and absolute discretion.

(a)    Subject to applicable Law and without limiting the generality of the obligations set forth in Section 2.1, unless the Parties otherwise agree or the benefits of any contract, agreement, arrangement, commitment or understanding described in this Section 2.8 are expressly conveyed to the applicable Party pursuant to this Agreement or an Ancillary Agreement, any contract or agreement, a portion of which is a GCP Asset, but the remainder of which is a Grace Asset (any such contract or agreement, a “Shared Contract”), shall be assigned in relevant part to the applicable member(s) of the applicable Group, if so assignable, or appropriately amended prior to, on or after the Effective Time, so that each Party or the member of its Group shall, as of the Effective Time, be entitled to the rights and benefits, and shall assume the related portion of any Liabilities, inuring to its respective businesses; provided, however, that (i) in no event shall any member of any Group be required to assign (or amend) any Shared Contract in its entirety or to assign a portion of any Shared Contract which is not assignable (or cannot be amended) by its terms (including any terms imposing consents or conditions on an assignment where such consents or conditions have not been obtained or fulfilled) and (ii) if any Shared Contract cannot be so partially assigned by its terms or otherwise, or cannot be amended or if such assignment or amendment would impair the benefit the parties thereto derive from such Shared Contract, then the Parties shall, and shall cause each of the members of their respective Groups to, take such other reasonable and permissible actions (including by providing prompt notice to the other Party with respect to any relevant claim of

Liability or other relevant matters arising in connection with a Shared Contract so as to allow such other Party the ability to exercise any applicable rights under such Shared Contract) to cause a member of the GCP Group or the Grace Group, as the case may be, to receive the rights and benefits of that portion of each Shared Contract that relates to the GCP Business or the Grace Business, as the case may be (in each case, to the extent so related), as if such Shared Contract had been assigned to (or amended to allow) a member of the applicable Group pursuant to this Section 2.8, and to bear the burden of the corresponding Liabilities (including any Liabilities that may arise by reason of such arrangement), as if such Liabilities had been assumed by a member of the applicable Group pursuant to this Section 2.8.

(b)    Each of Grace and GCP shall, and shall cause the members of its Group to, (i) treat for all Tax purposes the portion of each Shared Contract inuring to its respective businesses as Assets owned by, and/or Liabilities of, as applicable, such Party, or the members of its Group, as applicable, not later than the effective time of the Internal Distribution, and (ii) neither report nor take any Tax position (on a Tax Return or otherwise) inconsistent with such treatment (unless required by applicable Law).

(c)    Nothing in this Section 2.8 shall require any member of any Group to make any non-de minimis payment (except to the extent advanced, assumed or agreed in advance to be reimbursed by any member of the other Group), incur any non-de minimis obligation or grant any non-de minimis concession for the benefit of any member of any other Group in order to effect any transaction contemplated by this Section 2.8.

2.9    Bank Accounts; Cash Balances.

(a)    Each of Grace and GCP agree to take, or cause the applicable members of its Group to take, at or before the effective time of the Internal Distribution, all actions necessary to amend all contracts or agreements governing each bank and brokerage account owned by GCP or any other member of the GCP Group (collectively, the “GCP Accounts”) and all contracts or agreements governing each bank or brokerage account owned by Grace or any other member of the Grace Group (collectively, the “Grace Accounts”) so that each such GCP Account and Grace Account, if currently linked (whether by automatic withdrawal, automatic deposit or any other authorization to transfer funds from or to, hereinafter “Linked”) to any Grace Account or GCP Account, respectively, is de-Linked from such Grace Account or GCP Account, respectively.

(b)    It is intended that, following consummation of the actions contemplated by Section 2.9(a), there will be in place a cash management process pursuant to which the GCP Accounts will be managed and funds collected will be transferred into one (1) or more accounts maintained by GCP or a member of the GCP Group.

(c)    It is intended that, following consummation of the actions contemplated by Section 2.9(a), there will continue to be in place a cash management process pursuant to which the Grace Accounts will be managed and funds collected will be transferred into one (1) or more accounts maintained by Grace or a member of the Grace Group.

(d)    With respect to any outstanding checks issued or payments initiated by Grace, GCP, or any of the members of their respective Groups prior to the Effective Time, such outstanding checks and payments shall be honored following the Effective Time by the Person or Group owning the account on which the check is drawn or from which the payment was initiated, respectively.

(e)    As between Grace and GCP (and the members of their respective Groups), all payments made and reimbursements received at or after the effective time of the Internal Distribution by either Party (or member of its Group) that relate to a business, Asset or Liability of the other Party (or member of its Group), shall be held by such Party in trust for the use and benefit of the Party entitled thereto and, promptly following receipt by such Party of any such payment or reimbursement, such Party shall pay over, or shall cause the applicable member of its Group to pay over to the other Party the amount of such payment or reimbursement without right of set-off.

In lieu of any such fractional shares, each Record Holder that, but for the provisions of this Section 3.4(c), would be entitled to receive a fractional share interest of a GCP Share pursuant to the Distribution, shall be paid cash, without any interest thereon, as hereinafter provided. As soon as practicable after the Effective Time, Grace shall direct the Agent to determine the number of whole and fractional GCP Shares allocable to each Record Holder, to aggregate all such fractional shares into whole shares, and to sell the whole shares obtained thereby in the open market at the then-prevailing prices on behalf of the Record Holders that otherwise would be entitled to receive fractional share interests (with the Agent, in its sole and absolute discretion, determining when, how and through which broker-dealer and at what price to make such sales), and to cause to be distributed to each such Record Holder, in lieu of any fractional share, such Record Holder’s or owner’s ratable share of the total proceeds of such sale, after deducting any Taxes required to be withheld and applicable transfer Taxes, and after deducting the costs and expenses of such sale and distribution, including brokers fees and commissions. None of Grace, GCP or the Agent will be required to guarantee any minimum sale price for the fractional GCP Shares sold in accordance with this Section 3.4(c). Neither Grace nor GCP will be required to pay any interest on the proceeds from the sale of fractional shares. Neither the Agent nor the broker-dealers through which the aggregated fractional shares are sold shall be Affiliates of Grace or GCP. Solely for purposes of computing fractional share interests pursuant to this Section 3.4(c) and Section 3.4(d), the beneficial owner of Grace Shares held of record in the name of a nominee in any nominee account shall be treated as the Record Holder with respect to such shares.

(d)    Any GCP Shares or cash in lieu of fractional shares with respect to GCP Shares that remain unclaimed by any Record Holder one hundred and eighty (180) days after the Distribution Date shall be delivered to GCP, and GCP shall hold such GCP Shares for the account of such Record Holder, and the Parties agree that all obligations to provide such GCP Shares and cash, if any, in lieu of fractional share interests shall be obligations of GCP, subject in each case to applicable escheat or other abandoned property Laws, and Grace shall have no Liability with respect thereto.

(e)    Until the GCP Shares are duly transferred in accordance with this Section 3.4 and applicable Law, from and after the Effective Time, GCP will regard the Persons entitled to receive such GCP Shares as record holders of GCP Shares in accordance with the terms of the Distribution without requiring any action on the part of such Persons. GCP agrees that, subject to any transfers of such shares, from and after the Effective Time (i) each such holder will be entitled to receive all dividends payable on, and exercise voting rights and all other rights and privileges with respect to, the GCP Shares then held by such holder and (ii) each such holder will be entitled, without any action on the part of such holder, to receive evidence of ownership of the GCP Shares then held by such holder.

4.1    Release of Pre-Distribution Claims.

(a)    GCP Release of Grace. Except as provided in Sections 4.1(c) and 4.1(d), effective as of the Effective Time, GCP does hereby, for itself and each other member of the GCP Group and their respective successors and assigns, and, to the extent permitted by Law, all Persons who at any time prior to the Effective Time have been stockholders, directors, officers, agents or employees of any member of the GCP Group (in each case, in their respective capacities as such), remise, release and forever discharge (i) Grace and the members of the Grace Group, and their respective successors and assigns, and (ii) all Persons who at any time prior to the Effective Time have been stockholders, directors, officers, agents or employees of any member of the Grace Group (in each case, in their respective capacities as such), and their respective heirs, executors, administrators, successors and assigns , in each case from (A) all GCP Liabilities, (B) all Liabilities arising from or in connection with the transactions and all other activities to implement the Separation and the Distribution and (C) all Liabilities arising from or in connection with actions, inactions, events, omissions, conditions, facts or circumstances occurring or existing prior to the Effective Time (whether or not such Liabilities cease being contingent, mature, become known, are asserted or foreseen, or accrue, in each case before, at or after the Effective Time), in each case to the extent relating to, arising out of or resulting from the GCP Business, the GCP Assets or the GCP Liabilities.

(b)    Grace Release of GCP. Except as provided in Sections 4.1(c) and 4.1(d), effective as of the Effective Time, Grace does hereby, for itself and each other member of the Grace Group and their respective successors and assigns, and, to the extent permitted by Law, all Persons who at any time prior to the Effective Time have been stockholders, directors, officers, agents or employees of any member of the Grace Group (in each case, in their respective capacities as such), remise, release and forever discharge GCP and the members of the GCP Group and their respective successors and assigns, from (i) all Grace Liabilities, (ii) all Liabilities arising from or in connection with the transactions and all other activities to implement the Separation and the Distribution and (iii) all Liabilities arising from or in connection with actions, inactions, events, omissions, conditions, facts or circumstances occurring or existing prior to the Effective Time (whether or not such Liabilities cease being contingent, mature, become known, are asserted or foreseen, or accrue, in each case before, at or after the Effective Time), in each case to the extent relating to, arising out of or resulting from the Grace Business, the Grace Assets or the Grace Liabilities.

(c)    Obligations Not Affected. Nothing contained in Section 4.1(a) or 4.1(b) shall impair any right of any Person to enforce this Agreement, any Ancillary Agreement or any agreement, arrangement, commitment or understanding that is specified in Section 2.7(b) (or the applicable Schedules thereto) as not to terminate as of the Effective Time, in each case in accordance with its terms. Nothing contained in Section 4.1(a) or 4.1(b) shall release any Person from:

(i)    any Liability provided in or resulting from any agreement among any members of the Grace Group or the GCP Group that is specified in Section 2.7(b) (or the applicable Schedules thereto) as not to terminate as of the Effective Time, or any other Liability specified in Section 2.7(b) as not to terminate as of the Effective Time;

(ii)    any Liability, contingent or otherwise, assumed, transferred, assigned or allocated to the Group of which such Person is a member in accordance with, or any other Liability of any member of any Group under, this Agreement or any Ancillary Agreement;

(iii)    any Liability for the sale, lease, construction or receipt of goods, property or services purchased, obtained or used in the ordinary course of business by a member of one Group from a member of the other Group prior to the Effective Time;

(iv)    any Liability that the Parties may have with respect to indemnification or contribution pursuant to this Agreement, any Ancillary Agreement or otherwise for claims brought against the Parties by Third Parties, which Liability shall be governed by the provisions of this Article IV and Article V and, if applicable, the appropriate provisions of the Ancillary Agreements; or

(v)    any Liability the release of which would result in the release of any Person other than a Person released pursuant to this Section 4.1.

In addition, nothing contained in Section 4.1(a) shall release any member of the Grace Group from honoring its existing obligations to indemnify any director, officer or employee of GCP who was a director, officer or employee of any member of the Grace Group on or prior to the Effective Time, to the extent such director, officer or employee becomes a named defendant in any Action with respect to which such director, officer or employee was entitled to such indemnification pursuant to such existing obligations; it being understood that, if the underlying obligation giving rise to such Action is a GCP Liability, GCP shall indemnify Grace for such Liability (including Grace’s costs to indemnify the director, officer or employee) in accordance with the provisions set forth in this Article IV.

(d)    No Claims. GCP shall not make, and shall not permit any member of the GCP Group to make, any claim or demand, or commence any Action asserting any claim or demand, including any claim of contribution or any indemnification, against Grace or any other member of the Grace Group, or any other Person released pursuant to Section 4.1(a), with respect to any Liabilities released pursuant to Section 4.1(a). Grace shall not make, and shall not permit any other member of the Grace Group to make, any claim or demand, or commence any Action asserting any claim or demand, including any claim of contribution or any indemnification against GCP or any other member of the GCP Group, or any other Person released pursuant to Section 4.1(b), with respect to any Liabilities released pursuant to Section 4.1(b).

(e)    Execution of Further Releases. At any time at or after the Effective Time, at the request of either Party, the other Party shall cause each other member of its respective Group to execute and deliver releases reflecting the applicable provisions of this Section 4.1.

4.2    Indemnification by GCP. Except as otherwise specifically set forth in this Agreement or in any Ancillary Agreement, to the fullest extent permitted by Law, GCP shall, and shall cause the other members of the GCP Group to, indemnify, defend and hold harmless Grace,

each member of the Grace Group and each of their respective past, present and future directors, officers, employees and agents, in each case in their respective capacities as such, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “Grace Indemnitees”), from and against any and all Liabilities of the Grace Indemnitees relating to, arising out of or resulting from, directly or indirectly, any of the following items (without duplication):

(a)    any GCP Liability;

(b)    any failure of GCP, any other member of the GCP Group or any other Person to pay, perform or otherwise promptly discharge any GCP Liabilities in accordance with their terms, whether prior to, on or after the Effective Time;

(c)    any breach by GCP or any other member of the GCP Group of this Agreement or any of the Ancillary Agreements;

(d)    except to the extent it relates to a Grace Liability, any guarantee, indemnification or contribution obligation, surety bond or other credit support agreement, arrangement, commitment or understanding for the benefit of any member of the GCP Group by any member of the Grace Group that survives following the Distribution; and

(e)    any untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, with respect to all information contained in the Form 10, the Information Statement (as amended or supplemented if GCP shall have furnished any amendments or supplements thereto) or any other Disclosure Document, other than the matters described in clause (e) of Section 4.3.

4.3    Indemnification by Grace. Except as otherwise specifically set forth in this Agreement or in any Ancillary Agreement, to the fullest extent permitted by Law, from and after the Effective Time Grace shall, and shall cause the other members of the Grace Group to, indemnify, defend and hold harmless GCP, each member of the GCP Group and each of their respective past, present and future directors, officers, employees or agents, in each case in their respective capacities as such, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “GCP Indemnitees”), from and against any and all Liabilities of the GCP Indemnitees relating to, arising out of or resulting from, directly or indirectly, any of the following items (without duplication):

(a)    any Grace Liability;

(b)    any failure of Grace, any other member of the Grace Group or any other Person to pay, perform or otherwise promptly discharge any Grace Liabilities in accordance with their terms, whether prior to, on or after the Effective Time;

(c)    any breach by Grace or any other member of the Grace Group of this Agreement or any of the Ancillary Agreements;

(d)    except to the extent it relates to a GCP Liability, any guarantee, indemnification or contribution obligation, surety bond or other credit support agreement, arrangement, commitment or understanding for the benefit of any member of the Grace Group by any member of the GCP Group that survives following the Distribution; and

(e)    any untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, with respect to statements made explicitly in Grace’s name in the Form 10, the Information Statement (as amended or supplemented if GCP shall have furnished any amendments or supplements thereto) or any other Disclosure Document; it being agreed that the statements set forth on Schedule 4.3(e) shall be the only statements made explicitly in Grace’s name in the Form 10, the Information Statement or any other Disclosure Document.

4.4    Indemnification Obligations Net of Insurance Proceeds and Other Amounts.

(a)    The Parties intend that any Liability subject to indemnification, contribution or reimbursement pursuant to this Article IV or Article V will be net of Insurance Proceeds or other amounts actually recovered (net of any out-of-pocket costs or expenses incurred in the collection thereof) from any Person by or on behalf of the Indemnitee in respect of any indemnifiable Liability. Accordingly, the amount which either Party (an “Indemnifying Party”) is required to pay to any Person entitled to indemnification or contribution hereunder (an “Indemnitee”) will be reduced by any Insurance Proceeds or other amounts actually recovered (net of any out-of-pocket costs or expenses incurred in the collection thereof) from any Person by or on behalf of the Indemnitee in respect of the related Liability. If an Indemnitee receives a payment (an “Indemnity Payment”) required by this Agreement from an Indemnifying Party in respect of any Liability and subsequently receives Insurance Proceeds or any other amounts in respect of the related Liability, then the Indemnitee will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Insurance Proceeds or such other amounts (net of any out-of-pocket costs or expenses incurred in the collection thereof) had been received, realized or recovered before the Indemnity Payment was made.

(b)    The Parties agree that it is their intent that an insurer that would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto or, solely by virtue of any provision contained in this Agreement or any Ancillary Agreement, otherwise have any of its rights or obligations altered with respect thereto, it being understood that no insurer or any other Third Party shall be entitled to a “windfall” (i.e., a benefit they would not be entitled to receive in the absence of the indemnification provisions) by virtue of the indemnification and contribution provisions hereof. Each Party shall, and shall cause the other members of its Group to, use commercially reasonable efforts (taking into account the probability of success on the merits and the cost of expending such efforts, including attorneys’ fees and expenses) to collect or recover any Insurance Proceeds that may be collectible or recoverable respecting the Liabilities for which indemnification or contribution may be available

under this Article IV. Notwithstanding the foregoing, an Indemnifying Party may not delay making any indemnification payment required under the terms of this Agreement, or otherwise satisfying any indemnification obligation, pending the outcome of any Action to collect or recover Insurance Proceeds, and an Indemnitee need not attempt to collect any Insurance Proceeds prior to making a claim for indemnification or contribution or receiving any Indemnity Payment otherwise owed to it under this Agreement or any Ancillary Agreement.

4.5    Procedures for Indemnification of Third-Party Claims.

(a)    Notice of Claims. If, at or following the Effective Time, an Indemnitee shall receive notice or otherwise learn of the assertion by a Person (including any Governmental Authority) who is not a member of the Grace Group or the GCP Group of any claim or of the commencement by any such Person of any Action (collectively, a “Third-Party Claim”) with respect to which an Indemnifying Party may be obligated to provide indemnification to such Indemnitee pursuant to Section 4.2 or 4.3, or any other Section of this Agreement or any Ancillary Agreement, such Indemnitee shall give such Indemnifying Party written notice thereof as soon as practicable, but in any event within fourteen (14) days (or sooner if the nature of the Third-Party Claim so requires) after becoming aware of such Third-Party Claim. Any such notice shall describe the Third-Party Claim in reasonable detail, including the facts and circumstances giving rise to such claim for indemnification, and include copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third-Party Claim. Notwithstanding the foregoing, the failure of an Indemnitee to provide notice in accordance with this Section 4.5(a) shall not relieve an Indemnifying Party of its indemnification obligations under this Agreement, except to the extent to which the Indemnifying Party is actually prejudiced by the Indemnitee’s failure to provide notice in accordance with this Section 4.5(a).

(b)    Control of Defense. An Indemnifying Party may elect to defend (and seek to settle or compromise), at its own expense and with its own counsel, any Third-Party Claim; provided that, prior to the Indemnifying Party assuming and controlling defense of such Third-Party Claim, it shall first confirm to the Indemnitee in writing that, assuming the facts presented to the Indemnifying Party by the Indemnitee being true, the Indemnifying Party shall indemnify the Indemnitee for any such Liabilities to the extent resulting from, or arising out of, such Third-Party-Claim. Notwithstanding the foregoing, if the Indemnifying Party assumes such defense and, in the course of defending such Third-Party Claim, (i) the Indemnifying Party discovers that the facts presented at the time the Indemnifying Party acknowledged its indemnification obligation in respect of such Third-Party Claim were not true in all material respects and (ii) such untruth provides a reasonable basis for asserting that the Indemnifying Party does not have an indemnification obligation in respect of such Third-Party Claim, then (A) the Indemnifying Party shall not be bound by such acknowledgment, (B) the Indemnifying Party shall promptly thereafter provide the Indemnitee written notice of its assertion that it does not have an indemnification obligation in respect of such Third-Party Claim and (C) the Indemnitee shall have the right to assume the defense of such Third-Party Claim. Within thirty (30) days after the receipt of a notice from an Indemnitee in accordance with Section 4.5(a) (or sooner, if the nature of the Third-Party Claim so requires), the Indemnifying Party shall provide written notice to the Indemnitee indicating whether the Indemnifying Party shall assume responsibility for defending

the Third-Party Claim. If an Indemnifying Party elects not to assume responsibility for defending any Third-Party Claim or fails to notify an Indemnitee of its election within thirty (30) days after receipt of the notice from an Indemnitee as provided in Section 4.5(a), then the Indemnitee that is the subject of such Third-Party Claim shall be entitled to continue to conduct and control the defense of such Third-Party Claim.

(c)    Allocation of Defense Costs. If an Indemnifying Party has elected to assume the defense of a Third-Party Claim, then such Indemnifying Party shall be solely liable for all fees and expenses incurred by it in connection with the defense of such Third-Party Claim and shall not be entitled to seek any indemnification or reimbursement from the Indemnitee for any such fees or expenses incurred by the Indemnifying Party during the course of the defense of such Third-Party Claim by such Indemnifying Party, regardless of any subsequent decision by the Indemnifying Party to reject or otherwise abandon its assumption of such defense. If an Indemnifying Party elects not to assume responsibility for defending any Third-Party Claim or fails to notify an Indemnitee of its election within thirty (30) days after receipt of a notice from an Indemnitee as provided in Section 4.5(a), and the Indemnitee conducts and controls the defense of such Third-Party Claim and the Indemnifying Party has an indemnification obligation with respect to such Third-Party Claim, then the Indemnifying Party shall be liable for all reasonable fees and expenses incurred by the Indemnitee in connection with the defense of such Third-Party Claim.

(d)    Right to Monitor and Participate. An Indemnitee that does not conduct and control the defense of any Third-Party Claim, or an Indemnifying Party that has failed to elect to defend any Third-Party Claim as contemplated hereby, nevertheless shall have the right to employ separate counsel (including local counsel as necessary) of its own choosing to monitor and participate in (but not control) the defense of any Third-Party Claim for which it is a potential Indemnitee or Indemnifying Party, but the fees and expenses of such counsel shall be at the expense of such Indemnitee or Indemnifying Party, as the case may be, and the provisions of Section 4.5(c) shall not apply to such fees and expenses. Notwithstanding the foregoing, but subject to Sections 6.7 and 6.8, such Party shall cooperate with the Party entitled to conduct and control the defense of such Third-Party Claim in such defense and make available to the controlling Party, at the non-controlling Party’s expense, all witnesses, information and materials in such Party’s possession or under such Party’s control relating thereto as are reasonably required by the controlling Party. In addition to the foregoing, if any Indemnitee shall in good faith determine that such Indemnitee and the Indemnifying Party have actual or potential differing defenses or conflicts of interest between them that make joint representation inappropriate, then the Indemnitee shall have the right to employ separate counsel (including local counsel as necessary) and to participate in (but not control) the defense, compromise, or settlement thereof, and the Indemnifying Party shall bear the reasonable fees and expenses of such counsel for all Indemnitees.

(e)    No Settlement. Neither Party may settle or compromise any Third-Party Claim for which either Party is seeking to be indemnified hereunder without the prior written consent of the other Party, which consent may not be unreasonably withheld, unless such settlement or compromise is solely for monetary damages, does not involve any finding or

determination of wrongdoing or violation of Law by the other Party or another member of its Group and provides for a full, unconditional and irrevocable release of the other Party and the other members of its Group from all Liability in connection with the Third-Party Claim. The Parties hereby agree that if a Party presents the other Party with a written notice containing a proposal to settle or compromise a Third-Party Claim for which either Party is seeking to be indemnified hereunder and the Party receiving such proposal does not respond in any manner to the Party presenting such proposal within thirty (30) days (or within any such shorter time period that may be required by applicable Law or court order) of receipt of such proposal, then the Party receiving such proposal shall be deemed to have consented to the terms of such proposal.

(f)    Tax Sharing Agreement Governs. The above provisions of this Section 4.5 and the provisions of Section 4.6 do not apply to Taxes (Taxes being governed by the Tax Sharing Agreement). In the case of any conflict or inconsistency between this Agreement and the Tax Sharing Agreement in relation to any matters addressed by the Tax Sharing Agreement, the Tax Sharing Agreement shall prevail.

4.6    Additional Matters.

(a)    Timing of Payments. Indemnification or contribution payments in respect of any Liabilities for which an Indemnitee is entitled to indemnification or contribution under this Article IV shall be paid reasonably promptly (but in any event within thirty (30) days of the final determination of the indemnification or contribution amount to which the Indemnitee is entitled under this Article IV) by the Indemnifying Party to the Indemnitee as such Liabilities are incurred upon demand by the Indemnitee, including reasonably satisfactory documentation setting forth the basis for the amount of such indemnification or contribution payment, including documentation with respect to calculations made and consideration of any Insurance Proceeds that actually reduce the amount of such Liabilities. The indemnity and contribution provisions contained in this Article IV shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Indemnitee and (ii) the knowledge by the Indemnitee of Liabilities for which it might be entitled to indemnification hereunder.

(b)    Notice of Direct Claims. Any claim for indemnification or contribution under this Agreement or any Ancillary Agreement that does not result from a Third-Party Claim shall be asserted by written notice given by the Indemnitee to the applicable Indemnifying Party; provided, that the failure by an Indemnitee to so assert any such claim shall not prejudice the ability of the Indemnitee to do so at a later time except to the extent (if any) that the Indemnifying Party is prejudiced thereby. Such Indemnifying Party shall have a period of thirty (30) days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such thirty (30)-day period, such specified claim shall be conclusively deemed a Liability of the Indemnifying Party under this Section 4.6(b) or, in the case of any written notice in which the amount of the claim (or any portion thereof) is estimated, on such later date when the amount of the claim (or such portion thereof) becomes finally determined. If such Indemnifying Party does not respond within such thirty (30)-day period or rejects such claim in whole or in part, such Indemnitee shall, subject to the provisions of Article VII, be free to pursue such remedies as may be available to such Indemnifying Party as

contemplated by this Agreement and the Ancillary Agreements, as applicable, without prejudice to its continuing rights to pursue indemnification or contribution hereunder.

(c)    Pursuit of Claims Against Third Parties. If (i) a Party incurs any Liability arising out of this Agreement or any Ancillary Agreement, (ii) an adequate legal or equitable remedy is not available for any reason against the other Party to satisfy the Liability incurred by the incurring Party and (iii) a legal or equitable remedy may be available to the other Party against a Third Party for such Liability, then the other Party shall use its commercially reasonable efforts to cooperate with the incurring Party, at the incurring Party’s expense, to permit the incurring Party to obtain the benefits of such legal or equitable remedy against the Third Party.

(d)    Subrogation. In the event of payment by or on behalf of any Indemnifying Party to any Indemnitee in connection with any Third-Party Claim, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnitee as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third-Party Claim against any claimant or plaintiff asserting such Third-Party Claim or against any other Person. Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right, defense or claim.

(e)    Substitution. In the event of an Action in which the Indemnifying Party is not a named defendant, if either the Indemnitee or Indemnifying Party shall so request, the Parties shall endeavor to substitute the Indemnifying Party for the named defendant. If such substitution or addition cannot be achieved for any reason or is not requested, the named defendant shall allow the Indemnifying Party to manage the Action as set forth in Section 4.5 and this Section 4.6, and the Indemnifying Party shall fully indemnify the named defendant against all costs of defending the Action (including court costs, sanctions imposed by a court, attorneys’ fees, experts fees and all other external expenses), the costs of any judgment or settlement and the cost of any interest or penalties relating to any judgment or settlement.

4.7    Right of Contribution.

(a)    Contribution. If any right of indemnification contained in Section 4.2 or Section 4.3 is held unenforceable or is unavailable for any reason, or is insufficient to hold harmless an Indemnitee in respect of any Liability for which such Indemnitee is entitled to indemnification hereunder, then the Indemnifying Party shall contribute to the amounts paid or payable by the Indemnitees as a result of such Liability (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the members of its Group, on the one hand, and the Indemnitees entitled to contribution, on the other hand, as well as any other relevant equitable considerations.

(b)    Allocation of Relative Fault. Solely for purposes of determining relative fault pursuant to this Section 4.7, (i) any fault associated with the business conducted with the Delayed GCP Assets or Delayed GCP Liabilities (except for the gross negligence or intentional misconduct of a member of the Grace Group) or with the ownership, operation or activities prior

to the Effective Time of the GCP Business, the GCP Sold and Discontinued Businesses or a Legacy Sold and Discontinued Business constituting a GCP Asset shall be deemed to be the fault of GCP and the other members of the GCP Group, and no such fault shall be deemed to be the fault of Grace or any other member of the Grace Group, and (ii) any fault associated with the business conducted with Delayed Grace Assets or Delayed Grace Liabilities (except for the gross negligence or intentional misconduct of a member of the GCP Group) or with the ownership, operation or activities prior to the Effective Time of the Grace Business, the Grace Sold and Discontinued Businesses or a Legacy Sold and Discontinued Business constituting a Grace Asset shall be deemed to be the fault of Grace and the other members of the Grace Group, and no such fault shall be deemed to be the fault of GCP or any other member of the GCP Group.

4.8    Covenant Not to Sue or Assert Defense. Each Party hereby covenants and agrees that none of it, the other members of such Party’s Group or any Person claiming through it shall bring suit or otherwise assert any claim against any Indemnitee, or assert a defense against any claim asserted by any Indemnitee, before any court, arbitrator, mediator or administrative agency anywhere in the world, alleging that (a) the assumption or retention of any GCP Liabilities by GCP or a member of the GCP Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason; (b) the assumption or retention of any Grace Liabilities by Grace or a member of the Grace Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason or (c) the provisions of this Article IV are void or unenforceable for any reason.

4.9    Remedies Cumulative. The remedies provided in this Article IV shall be cumulative and, subject to the provisions of Article VIII, shall not preclude assertion by any Indemnitee of any other rights or the seeking of any and all other remedies against any Indemnifying Party.

4.10    Survival of Indemnities. The rights and obligations of each of Grace and GCP and their respective Indemnitees under this Article IV shall survive (a) the sale or other transfer by either Party or any member of its Group of any assets or businesses or the assignment by it of any liabilities or (b) any merger, consolidation, business combination, sale of all or substantially all of its Assets, restructuring, recapitalization, reorganization or similar transaction involving either Party or any of the other members of its Group.

4.11    Real Property Transfer Documents. Notwithstanding anything to the contrary in any of the Transfer Documents entered into in connection with the transfer of Real Property, no warranty or any other provision contained therein shall act to increase either Party’s Liability beyond as set forth in this Agreement.

5.1    Insurance Matters.

(a)    Grace and GCP agree to cooperate in good faith to provide for an orderly transition of insurance coverage from the date hereof through the Effective Time. In no event shall any member of the Grace Group or any Grace Indemnitee have Liability or obligation whatsoever to any member of the GCP Group in the event that any insurance policy or other contract or policy of insurance shall be terminated or otherwise cease to be in effect for any reason, shall be unavailable or inadequate to cover any Liability of any member of the GCP Group for any reason whatsoever or shall not be renewed or extended beyond the current expiration date.

(b)    From and after the Effective Time, with respect to any losses, damages and Liability incurred by any member of the GCP Group prior to the Effective Time, Grace will provide GCP with access to, and GCP may, upon ten (10) days’ prior written notice to Grace, make claims under, Grace’s insurance policies in place immediately prior to the Effective Time and Grace’s historical policies of insurance, but solely to the extent that such policies provided coverage for members of the GCP Group prior to the Effective Time; provided that such access to, and the right to make claims under, such insurance policies, shall be subject to the terms and conditions of such insurance policies, including but not limited to any limits on coverage or scope, and any deductibles, self-insured retentions, retrospectively rated insurance plans and other fees and expenses, and shall be subject to the following additional conditions:

(i)    GCP shall report any claim to Grace as promptly as practicable, and in any event in sufficient time so that such claim may be made in accordance with the policies’ terms and conditions;

(ii)    GCP and the other members of the GCP Group shall be responsible for making payments directly to insurers where possible, and shall indemnify, hold harmless and reimburse Grace and the members of the Grace Group for any deductibles, self-insured retention, retrospective premium payments, and fees and expenses incurred by any member of the Grace Group to the extent resulting from any access to, or any claims made by GCP or any other members of the GCP Group under, any insurance provided pursuant to this Section 5.1(b), including claims previously reported and any indemnity payments, settlements, judgments, legal fees and allocated claims expenses and claim handling fees, whether such claims are made by a member of the GCP Group, employees or Third Parties; and

(iii)    GCP shall exclusively bear (and no member of the Grace Group shall have any obligation to repay or reimburse any member of the GCP Group for) and shall be liable for all uninsured, uncovered, unavailable or uncollectible amounts of all such claims made by any member of the GCP Group under the policies as provided for in this Section 5.1(b). In the event an insurance policy aggregate is exhausted, or believed likely to be exhausted, due to noticed claims, the GCP Group, on the one hand, and the Grace Group, on the other hand, shall be responsible for their pro rata portion of the reinstatement premium, if any, based upon the losses of such Group submitted to Grace’s insurance carrier(s) (including any submissions prior to the Effective Time). To the extent that the Grace Group or the GCP Group is allocated more than its pro rata portion

of such premium due to the timing of losses submitted to Grace’s insurance carrier(s), the other party shall promptly pay the first party an amount so that each Group has been properly allocated its pro rata portion of the reinstatement premium. Subject to the following sentence, Grace may elect not to reinstate the policy aggregate. In the event that Grace elects not to reinstate the policy aggregate, it shall provide prompt written notice to GCP, and GCP may direct Grace in writing to, and Grace shall, in such case, reinstate the policy aggregate; provided that GCP shall be responsible for all reinstatement premiums and other costs associated with such reinstatement.

(c)    Except as provided in Section 5.1(b), from and after the Effective Time, no member of the GCP Group shall have any rights to or under any of the insurance policies of any member of the Grace Group. At the Effective Time, the members of the GCP Group shall have in effect all insurance programs required to comply with the GCP Group’s contractual obligations and such other insurance policies required by Law or as reasonably necessary or appropriate for companies operating a businesses similar to GCP’s. Such insurance programs may include general liability, commercial auto liability, workers’ compensation, employer’s liability, product liability, property, cargo, employee dishonesty/crime, directors’ and officers’ liability and fiduciary liability.

(d)    No member of the GCP Group, in connection with making a claim under any insurance policy of any member of the Grace Group pursuant to this Section 5.1, shall take any action that would be reasonably likely to (i) have an adverse impact on the then-current relationship between any member of the Grace Group, on the one hand, and the applicable insurance company, on the other hand; (ii) result in the applicable insurance company terminating or reducing coverage, or increasing the amount of any premium owed by any member of the Grace Group under the applicable insurance policy or (iii) otherwise compromise, jeopardize or interfere with the rights of any member of the Grace Group under the applicable insurance policy, provided that, for avoidance of doubt that this Section 5.1(d) shall not preclude or otherwise restrict any member of the GCP Group from reporting claims to insurers in the ordinary course of business.

(e)    All payments and reimbursements by GCP pursuant to this Section 5.1 will be made within fifteen (15) days after GCP’s receipt of an invoice therefor from Grace. In the event that GCP makes payments to insurance companies directly, then GCP shall make payments in compliance with the requirements and policies and procedures with respect to insurance payments in effect prior to the Effective Time. If Grace incurs costs to enforce GCP’s obligations herein, GCP agrees to indemnify and hold harmless Grace for such enforcement costs, including reasonable attorneys’ fees pursuant to Section 4.6. Grace shall retain the exclusive right to control its insurance policies and programs, including the right to exhaust, settle, release, commute, buy-back or otherwise resolve disputes with respect to any of its insurance policies and programs and to amend, modify or waive any rights under any such insurance policies and programs, notwithstanding whether any such policies or programs apply to any GCP Liabilities and/or claims GCP has made or could make in the future. No member of the GCP Group shall, without the prior consent of Grace or otherwise as expressly permitted under this Agreement, erode, exhaust, settle, release, commute, buyback or otherwise resolve

disputes with Grace’s insurers with respect to any of Grace’s insurance policies and programs, or amend, modify or waive any rights under any such insurance policies and programs. GCP shall cooperate with Grace and share such information as is reasonably necessary in order to permit Grace to manage and conduct its insurance matters as it deems appropriate. No member of the Grace Group shall have any obligation to secure extended reporting for any claims under any Liability policies of any member of the Grace Group for any acts or omissions by any member of the GCP Group incurred prior to the Effective Time.

(f)    This Agreement shall not be considered as an attempted assignment of any policy of insurance or as a contract of insurance and shall not be construed to waive any right or remedy of any member of the Grace Group in respect of any insurance policy or any other contract or policy of insurance.

(g)    GCP does hereby, for itself and each other member of the GCP Group, agree that no member of the Grace Group shall have any Liability whatsoever as a result of the insurance policies and practices of the members of the Grace Group as in effect at any time, including as a result of the level or scope of any such insurance, the creditworthiness of any insurance carrier, the terms and conditions of any policy, the adequacy or timeliness of any notice to any insurance carrier with respect to any claim or potential claim or otherwise.

5.2    Late Payments. Except as expressly provided to the contrary in this Agreement or in any Ancillary Agreement, any amount not paid when due pursuant to this Agreement or any Ancillary Agreement (and any amounts billed or otherwise invoiced or demanded and properly payable that are not paid within thirty (30) days of such bill, invoice or other demand) shall accrue interest at a rate per annum equal to Prime Rate plus two (2%) percent.

5.3    Treatment of Payments for Tax Purposes. For all tax purposes, the Parties agree to treat (i) any payment required by this Agreement (other than payments with respect to interest accruing after the Effective Time) as either a contribution by Grace Conn to GCP or a distribution by GCP to Grace or Grace Conn, as the case may be, occurring immediately prior to the effective time of the Internal Spin or the Effective Time or as a payment of an assumed or retained Liability, as the case may be, in each case, as determined by Grace, in its sole discretion, and (ii) any payment of interest as taxable or deductible, as the case may be, to the Party entitled under this Agreement to retain such payment or required under this Agreement to make such payment, in either case except as otherwise required by applicable Law.

5.4    Inducement. GCP acknowledges and agrees that Grace’s willingness to cause, effect and consummate the Separation and the Distribution has been conditioned upon and induced by GCP’s covenants and agreements in this Agreement and the Ancillary Agreements, including the assumption by members of the GCP Group of the GCP Liabilities to be assumed by them pursuant to the Separation and the provisions of this Agreement and GCP’s covenants and agreements contained in Article IV.

5.5    Post-Effective Time Conduct. The Parties acknowledge that, after the Effective Time, each Party shall be independent of the other Party, with responsibility for its own

actions and inactions and its own Liabilities relating to, arising out of or resulting from the conduct of its business, operations and activities following the Effective Time, except as may otherwise be provided in any Ancillary Agreement, and each Party shall (except as otherwise provided in Article IV) use commercially reasonable efforts to prevent such Liabilities from being inappropriately borne by the other Party.

6.1    Agreement for Exchange of Information.

(a)    Subject to Section 6.9 and any other applicable confidentiality obligations, each of Grace and GCP, on behalf of itself and each member of its Group, agrees to use commercially reasonable efforts to provide or make available, or cause to be provided or made available, to the other Party and the other members of such other Party’s Group, at any time before, on or after the Effective Time, as soon as reasonably practicable after written request therefor from the other Party or its Group members, any information (or a copy thereof) in the possession or under the control of such first Party or its Group members to the extent that (i) such information relates to the GCP Business, or any GCP Asset or GCP Liability, if a member of the GCP Group is the requesting Party, or to the Grace Business, or any Grace Asset or Grace Liability, if a member of the Grace Group is the requesting Party, (ii) such information is required by the requesting Party to comply with its obligations under this Agreement or any Ancillary Agreement or (iii) such information is required by the requesting Party to comply with any obligation imposed by any Governmental Authority; provided, however, that, in the event that the Party to whom the request has been made determines that any such provision of information could be detrimental to the Party providing the information, violate any Law or agreement, or waive any privilege available under applicable Law, including any attorney-client privilege, then the Parties shall use commercially reasonable efforts to permit compliance with such obligations to the extent and in a manner that avoids any such harm or consequence.  The Party providing information pursuant to this Section 6.1 shall only be obligated to provide such information in the form, condition and format in which it then exists, and in no event shall such Party be required to perform any improvement, modification, conversion, updating or reformatting of any such information, and nothing in this Section 6.1 shall expand the obligations of a Party under Section 6.4.

(i)    Without limiting the generality of the foregoing, until the first GCP fiscal year end occurring after the Effective Time (and for a reasonable period of time afterwards as required for each Party to prepare consolidated financial statements or complete a financial statement audit for the fiscal year during which the Distribution Date occurs), each Party shall use its commercially reasonable efforts to cooperate with the other Party’s information requests to enable (i) the other Party to meet its timetable for dissemination of its earnings releases, financial statements and management’s assessment of the effectiveness of its disclosure controls and procedures and its internal control over financial reporting in accordance with Items 307 and 308, respectively, of Regulation S-K promulgated under the Exchange Act and (ii) the other Party’s accountants to timely complete their review of the quarterly financial statements and

audit of the annual financial statements, including, to the extent applicable to such Party, its auditor’s audit of its internal control over financial reporting and management’s assessment thereof in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, the SEC’s and Public Company Accounting Oversight Board’s rules and auditing standards thereunder and any other applicable Laws.

6.2    Ownership of Information. The provision of any information pursuant to Section 6.1 or Section 6.7 shall not affect the ownership of such information (which shall be determined solely in accordance with the terms of this Agreement and the Ancillary Agreements), or constitute a grant of rights in or to any such information.

6.3    Compensation for Providing Information. The Party requesting information agrees to reimburse the other Party for the reasonable costs, if any, of creating, gathering, copying, transporting and otherwise complying with the request with respect to such information (including any reasonable costs and expenses incurred in any review of information for purposes of protecting Privileged Information of the providing Party or in connection with the restoration of backup media for purposes of providing the requested information). Except as may be otherwise specifically provided elsewhere in this Agreement, any Ancillary Agreement or any other agreement between the Parties, such costs shall be computed in accordance with the providing Party’s standard methodology and procedures.

6.4    Record Retention. To facilitate the possible exchange of information pursuant to this Article VI and other provisions of this Agreement after the Effective Time, the Parties agree to use their commercially reasonable efforts, which shall be no less rigorous than those used for retention of such Party’s own information, to retain all information in their respective possession or control at the Effective Time in accordance with the policies of Grace as in effect at the Effective Time or such other policies as may be adopted by Grace after the Effective Time (provided, in the case of GCP, that Grace notifies GCP of any such change); provided, however, that in the case of any information relating to Taxes, such retention period shall be extended to the expiration of the applicable statute of limitations (giving effect to any extensions thereof). Notwithstanding the foregoing, Section 9.01 of the Tax Sharing Agreement will govern the retention of Tax related records, and Section 9.01 of the Employee Matters Agreement will govern the retention of employment and benefits related records.

6.5    Limitations of Liability. Neither Party shall have any Liability to the other Party in the event that any information exchanged or provided pursuant to this Agreement is found to be inaccurate in the absence of gross negligence or willful misconduct by the Party providing such information. Neither Party shall have any Liability to the other Party if any information is destroyed after commercially reasonable efforts by such first Party to comply with the provisions of Section 6.4.

6.6    Other Agreements Providing for Exchange of Information.

(a)    The rights and obligations granted under this Article VI are subject to any specific limitations, qualifications or additional provisions on the sharing, exchange, retention or confidential treatment of information set forth in any Ancillary Agreement.

(b)    Any party that receives, pursuant to a request for information in accordance with this Article VI, Tangible Information that is not relevant to its request shall (i) return it to the providing Party or, at the providing Party’s request, destroy such Tangible Information and (ii) deliver to the providing Party written confirmation that such Tangible Information was returned or destroyed, as the case may be, which confirmation shall be signed by an authorized representative of the requesting Party.

6.7    Production of Witnesses; Records; Cooperation.

(a)    After the Effective Time, except in the case of an adversarial Action or Dispute between Grace and GCP, or any members of their respective Groups, each Party shall use its commercially reasonable efforts to make available to the other Party, upon written request, the former, current and future directors, officers, employees, other personnel and agents of the members of its respective Group as witnesses and any books, records or other documents within its control or which it otherwise has the ability to make available without undue burden, to the extent that any such person (giving consideration to business demands of such directors, officers, employees, other personnel and agents) or books, records or other documents may reasonably be required in connection with any Action in which the requesting Party (or other member of its Group) may from time to time be involved, regardless of whether such Action is a matter with respect to which indemnification may be sought hereunder. The requesting Party shall bear all costs and expenses in connection therewith.

(b)    Without limiting the foregoing, the Parties shall cooperate and consult to the extent reasonably necessary with respect to any Actions.

(c)    Without limiting any provision of this Section 6.7 and subject to the terms of the Cross License Agreement, each of the Parties agrees to cooperate, and to cause each member of its respective Group to cooperate, with each other in the defense of any infringement or similar claim with respect any Intellectual Property and shall not claim to acknowledge, or permit any member of its respective Group to claim to acknowledge, the validity or infringing use of any Intellectual Property of a Third Party in a manner that would hamper or undermine the defense of such infringement or similar claim.

(d)    The obligation of the Parties to provide witnesses pursuant to this Section 6.7 is intended to be interpreted in a manner so as to facilitate cooperation and shall include the obligation to provide as witnesses inventors and other officers without regard to whether the witness or the employer of the witness could assert a possible business conflict (subject to the exception set forth in the first sentence of Section 6.7(a)).

6.8    Privileged Matters.

(a)    The Parties recognize that legal and other professional services that have been and will be provided prior to the Effective Time have been and will be rendered for the collective benefit of each of the respective members of the Grace Group and the GCP Group, and that each of the respective members of the Grace Group and the GCP Group should be deemed to be the client with respect to such services for the purposes of asserting all privileges which may

be asserted under applicable Law in connection therewith. The Parties recognize that legal and other professional services will be provided following the Effective Time, which services will be rendered solely for the benefit of the Grace Group or the GCP Group, as the case may be.

(b)    The Parties agree as follows:

(i)    Grace shall be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any Privileged Information that relates solely to the Grace Business, the Grace Sold and Discontinued Businesses and the Legacy Sold and Discontinued Businesses that constitute Grace Assets and not to the GCP Business, the GCP Sold and Discontinued Businesses or the Legacy Sold and Discontinued Businesses that constitute GCP Assets, whether or not the Privileged Information is in the possession or under the control of any member of the Grace Group or any member of the GCP Group. Grace shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any Privileged Information that relates solely to any Grace Liabilities resulting from any Actions that are now pending or may be asserted in the future, whether or not the Privileged Information is in the possession or under the control of any member of the Grace Group or any member of the GCP Group; and

(ii)    GCP shall be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any Privileged Information that relates solely to the GCP Business the GCP Sold and Discontinued Businesses and the Legacy Sold and Discontinued Businesses that constitute GCP Assets and not to the Grace Business the Grace Sold and Discontinued Businesses or the Legacy Sold and Discontinued Businesses that constitute Grace Assets, whether or not the Privileged Information is in the possession or under the control of any member of the GCP Group or any member of the Grace Group. GCP shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any Privileged Information that relates solely to any GCP Liabilities resulting from any Actions that are now pending or may be asserted in the future, whether or not the privileged Information is in the possession or under the control of any member of the GCP Group or any member of the Grace Group.

(iii)    If the Parties do not agree as to whether certain information is Privileged Information, then such information shall be treated as Privileged Information, and the Party that believes that such information is Privileged Information shall be entitled to control the assertion or waiver of all privileges and immunities in connection with any such information unless the Parties otherwise agree.  The Parties shall use the procedures set forth in Article VII to resolve any disputes as to whether any information relates (A) solely to the Grace Business, the Grace Sold and Discontinued Businesses or the Legacy Sold and Discontinued Businesses that constitute Grace Assets, (B) solely to the GCP Business, the GCP Sold and Discontinued Businesses or the Legacy Sold and Discontinued Businesses that constitute GCP Assets or (C) to both.

(c)    Subject to the remaining provisions of this Section 6.8, the Parties agree that they shall have a shared privilege or immunity with respect to all privileges and immunities not allocated pursuant to Section 6.8(b) and all privileges and immunities relating to any Actions or other matters that involve both Parties (or one or more members of their respective Groups) and in respect of which both Parties have Liabilities under this Agreement, and that no such shared privilege or immunity may be waived by either Party without the consent of the other Party.

(d)    If any Dispute arises between the Parties or any members of their respective Group regarding whether a privilege or immunity should be waived to protect or advance the interests of either Party and/or any member of their respective Group, each Party agrees that it shall (i) negotiate with the other Party in good faith, (ii) endeavor to minimize any prejudice to the rights of the other Party and (iii) not unreasonably withhold consent to any request for waiver by the other Party.  Further, each Party specifically agrees that it shall not withhold its consent to the waiver of a privilege or immunity for any purpose except in good faith to protect its own legitimate interests.

(e)    In the event of any adversarial Action or Dispute between Grace and GCP, or any members of their respective Groups, either Party may waive a privilege in which the other Party or member of such other Party’s Group has a shared privilege, without obtaining consent pursuant to Section 6.8(c), provided that such waiver of a shared privilege shall be effective only as to the use of information with respect to the Action or Dispute between the Parties and/or the applicable members of their respective Groups, and shall not operate as a waiver of the shared privilege with respect to any Third Party.

(f)    Upon receipt by either Party, or by any other member of its respective Group, of any subpoena, discovery or other request that may reasonably be expected to result in the production or disclosure of Privileged Information subject to a shared privilege or immunity or as to which the other Party has the sole right hereunder to assert a privilege or immunity, or if either Party obtains knowledge that any of its, or any member of its respective Group’s, current or former directors, officers, agents or employees have received any subpoena, discovery or other requests that may reasonably be expected to result in the production or disclosure of such Privileged Information, such Party shall promptly notify the other Party of the existence of the request (which notice shall be delivered to such other Party no later than ten (10) business days following the receipt of any such subpoena, discovery or other request) and shall provide the other Party a reasonable opportunity to review the Privileged Information and to assert any rights it or they may have under this Section 6.8 or otherwise, to prevent the production or disclosure of such Privileged Information.

(g)    Any furnishing of, or access or transfer of, any information pursuant to this Agreement is made in reliance on the agreement of Grace and GCP set forth in this Section 6.8 and in Section 6.9 to maintain the confidentiality of Privileged Information and to assert and maintain all applicable privileges and immunities. The Parties agree that their respective rights to any access to information, witnesses and other Persons, the furnishing of notices and documents and other cooperative efforts between the Parties contemplated by this

Agreement, and the transfer of Privileged Information between the Parties and members of their respective Groups pursuant to this Agreement, shall not be deemed a waiver of any privilege that has been or may be asserted under this Agreement or otherwise.

(h)    In connection with any matter contemplated by Section 6.7 or this Section 6.8, the Parties agree to, and to cause the applicable other members of their Group to, use commercially reasonable efforts to maintain their respective separate and joint privileges and immunities, including by executing joint defense and/or common interest agreements where necessary or useful for this purpose.

6.9    Confidentiality.

(a)    Confidentiality. Subject to Section 6.10, from and after the Effective Time until the five-year anniversary of the Effective Time, each of Grace and GCP, on behalf of itself and each other member of its respective Group, agrees to hold, and to cause its respective Representatives to hold, in strict confidence, with at least the same degree of care that applies to Grace’s confidential and proprietary information pursuant to policies in effect as of the Effective Time, all confidential and proprietary information concerning any member of the other Party’s Group or their respective businesses that is either in its possession (including confidential and proprietary information in its possession prior to the date hereof) or furnished by any member of such Party’s Group or their respective Representatives at any time pursuant to this Agreement, any Ancillary Agreement or otherwise, and shall not use any such confidential and proprietary information other than for such purposes as shall be expressly permitted hereunder or thereunder, except, in each case, to the extent that such confidential and proprietary information has been (i) in the public domain or generally available to the public, other than as a result of a disclosure by any member of such first Party’s Group or any of their respective Representatives in violation of this Agreement, (ii) later lawfully acquired from other sources by such first Party (or any other member of such Party’s Group) which sources are not themselves bound by a confidentiality obligation or other contractual, legal or fiduciary obligation of confidentiality with respect to such confidential and proprietary information or (iii) independently developed or generated without reference to or use of any proprietary or confidential information of any member of such first Party’s Group. If any confidential and proprietary information of one Party or any other member of its Group is disclosed to any member of the other Party’s Group in connection with providing services to any member of such first Party’s Group under this Agreement or any Ancillary Agreement, then such disclosed confidential and proprietary information shall be used only as required to perform such services.

(b)    No Release; Return or Destruction. Each Party agrees not to release or disclose, or permit to be released or disclosed, any information addressed in Section 6.9(a) to any other Person, except its Representatives who need to know such information in their capacities as such (who shall be advised of their obligations hereunder with respect to such information), and except in compliance with Section 6.10. Without limiting the foregoing, when any such information is no longer needed for the purposes contemplated by this Agreement or any Ancillary Agreement, each Party will promptly after request of the other Party either return to the other Party all such information in a tangible form (including all copies thereof and all notes,

extracts or summaries based thereon) or notify the other Party in writing that it has destroyed such information (and such copies thereof and such notes, extracts or summaries based thereon).

(c)    Third-Party Information; Privacy or Data Protection Laws. Each Party acknowledges that it and members of its Group may presently have and, following the Effective Time, may gain access to or possession of confidential or proprietary information of, or personal information relating to, Third Parties (i) that was received under confidentiality or non-disclosure agreements entered into between such Third Parties, on the one hand, and a member of the other Party’s Group, on the other hand, prior to the Effective Time or (ii) that, as between the two Parties, was originally collected by a member of the other Party’s Group and that may be subject to and protected by privacy, data protection or other applicable Laws. Each Party agrees that it shall hold, protect and use, and shall cause the other members of its Group and its and their respective Representatives to hold, protect and use, in strict confidence the confidential and proprietary information of, or personal information relating to, Third Parties in accordance with privacy, data protection or other applicable Laws and the terms of any agreements that were either entered into before the Effective Time or affirmative commitments or representations that were made before the Effective Time by, between or among the members of the other Party’s Group, on the one hand, and such Third Parties, on the other hand.

6.10    Protective Arrangements. In the event that a Party or any other member of its Group either determines on the advice of its counsel that it is required to disclose any information pursuant to applicable Law or receives any request or demand under lawful process or from any Governmental Authority to disclose or provide information of any member of the other Party’s Group that is subject to the confidentiality provisions hereof, such Party shall notify the other Party (to the extent legally permitted) as promptly as practicable under the circumstances prior to disclosing or providing such information and shall cooperate, at the expense of the other Party, in seeking any appropriate protective order requested by the other Party. In the event that such other Party fails to receive such appropriate protective order in a timely manner and the Party receiving the request or demand reasonably determines that its failure to disclose or provide such information shall actually prejudice the Party receiving the request or demand, then the Party that received such request or demand may thereafter disclose or provide information to the extent required by such Law (as so advised by its counsel) or by lawful process or such Governmental Authority, and the disclosing Party shall promptly provide the other Party with a copy of the information so disclosed, in the same form and format so disclosed, together with a list of all Persons to whom such information was disclosed, in each case to the extent legally permitted.

6.11    Name Change Obligation. GCP hereby covenants and agrees that as soon as reasonably practicable, and in no event later than eighteen (18) months, following the Effective Time, or such longer period as may be required by applicable Law, GCP shall, and shall cause each applicable member of the GCP Group to (i) change its legal name to a name that does not include the word “Grace”, nor uses the Grace Name and Grace Marks, and (ii) take such actions as may be necessary to cause any GCP Permits held by each such entity to refer to such new legal name and to eliminate the word “Grace” and any references to the Grace Name and Grace Marks.

7.1    Good-Faith Negotiation. Subject to Section 7.4, either Party seeking resolution of any dispute, controversy or claim arising out of or relating to this Agreement or Ancillary Agreement (including regarding whether any Assets are GCP Assets, any Liabilities are GCP Liabilities or the validity, interpretation, breach or termination of this Agreement or any Ancillary Agreement) (a “Dispute”), shall provide written notice thereof to the other Party (the “Initial Notice”), and within thirty (30) days of the delivery of the Initial Notice, the Parties shall attempt in good faith to negotiate a resolution of the Dispute. The negotiations shall be conducted by executives who hold, at a minimum, the title of vice president and who have authority to settle the Dispute. All such negotiations shall be confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence. If the Parties are unable for any reason to resolve a Dispute within thirty (30) days after the delivery of such notice or if a Party reasonably concludes that the other Party is not willing to negotiate as contemplated by this Section 7.1, the Dispute shall be submitted to mediation in accordance with Section 7.2.

7.2    Mediation. Any Dispute not resolved pursuant to Section 7.1 shall, at the written request of a Party (a “Mediation Request”), be submitted to nonbinding mediation in accordance with the then current International Institute for Conflict Prevention and Resolution (“CPR”) Mediation Procedure, except as modified herein. The mediation shall be held in (i) New York, New York or (ii) such other place as the Parties may mutually agree in writing. The Parties shall have twenty (20) days from receipt by a Party of a Mediation Request to agree on a mediator. If no mediator has been agreed upon by the Parties within twenty (20) days of receipt by a Party of a Mediation Request, then a Party may request (on written notice to the other Party), that CPR appoint a mediator in accordance with the CPR Mediation Procedure. All mediation pursuant to this clause shall be confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence, and no oral or documentary representations made by the Parties during such mediation shall be admissible for any purpose in any subsequent proceedings. No Party shall disclose or permit the disclosure of any information about the evidence adduced or the documents produced by the other Party in the mediation proceedings or about the existence, contents or results of the mediation without the prior written consent of such other Party, except in the course of a judicial or regulatory proceeding or as may be required by Law or requested by a Governmental Authority or securities exchange. Before making any disclosure permitted by the preceding sentence, the Party intending to make such disclosure shall, to the extent reasonably practicable, give the other Party reasonable written notice of the intended disclosure and afford the other party a reasonable opportunity to protect its interests. If the Dispute has not been resolved within sixty (60) days of the appointment of a mediator, or within ninety (90) days after receipt by a Party of a Mediation Request (whichever occurs sooner), or within such longer period as the Parties may agree to in writing, then the Dispute shall be submitted to binding arbitration in accordance with Section 7.3.

7.3    Arbitration.

(a)    In the event that a Dispute has not been resolved within sixty (60) days of the appointment of a mediator in accordance with Section 7.2, or within ninety (90) days after receipt by a Party of a Mediation Request (whichever occurs sooner), or within such longer period as the Parties may agree to in writing, then such Dispute shall, upon the written request of a Party (the “Arbitration Request”) be submitted to be finally resolved by binding arbitration pursuant to the CPR Arbitration Procedure. The arbitration shall be held in the same location as the mediation pursuant to Section 7.2. Unless otherwise agreed by the Parties in writing, any Dispute to be decided pursuant to this Section 7.3 will be decided (i) before a sole arbitrator if the amount in dispute, inclusive of all claims and counterclaims, totals less than $2 million, or (ii) by a panel of three (3) arbitrators if the amount in dispute, inclusive of all claims and counterclaims, totals $2 million or more.

(b)    If the arbitration will be before a panel of three (3) arbitrators, the arbitrators will be chosen as follows: (i) within fifteen (15) days from the date of the receipt of the Arbitration Request, each Party will name an arbitrator; and (ii) the two (2) Party-appointed arbitrators will thereafter, within thirty (30) days from the date on which the second of the two (2) arbitrators was named, name a third, independent arbitrator who will act as chairperson of the arbitral tribunal. In the event that either Party fails to name an arbitrator within fifteen (15) days from the date of receipt of the Arbitration Request, then upon written application by either Party, that arbitrator shall be appointed pursuant to the CPR Arbitration Procedure. In the event that the two (2) Party-appointed arbitrators fail to appoint the third, then the third, independent arbitrator will be appointed pursuant to the CPR Arbitration Procedure. If the arbitration will be before a sole independent arbitrator, then the sole independent arbitrator will be appointed by agreement of the Parties within fifteen (15) days of the date of receipt of the Arbitration Request. If the Parties cannot agree on a sole independent arbitrator, then upon written application by either Party, the sole independent arbitrator will be appointed pursuant to the CPR Arbitration Procedure.

(c)    The arbitrator(s) will have the right to award, on an interim basis, or include in the final award, any relief which it (or they) deem(s) proper in the circumstances, including money damages (with interest on unpaid amounts from the due date), injunctive relief (including specific performance) and attorneys’ fees and costs; provided that the arbitrator(s) will not award any relief not specifically requested by the Parties and, in any event, will not award any indirect, punitive, exemplary, remote, consequential, speculative or similar damages in excess of compensatory damages of the other arising in connection with the transactions contemplated hereby (other than any such Liability with respect to a Third-Party Claim). Upon selection of the arbitrator(s) following any grant of interim relief by a special arbitrator or court pursuant to Section 7.4, the arbitrator(s) may affirm or disaffirm that relief, and the Parties will seek modification or rescission of the order entered by the court as necessary to accord with the decision of the arbitrator(s). The award of the arbitrator(s) shall be final and binding on the Parties, and may be enforced in any court of competent jurisdiction. The initiation of mediation or arbitration pursuant to this Article VII will toll the applicable statute of limitations for the duration of any such proceedings.

7.4    Litigation and Unilateral Commencement of Arbitration. Notwithstanding the foregoing provisions of this Article VII, (a) a Party may seek preliminary provisional or injunctive judicial relief with respect to a Dispute without first complying with the procedures set forth in Section 7.1, Section 7.2 and Section 7.3 if such action is reasonably necessary to avoid irreparable damage and (b) either Party may initiate arbitration before the expiration of the periods specified in Section 7.2 and Section 7.3 if (i) such Party has submitted a Mediation Request or Arbitration Request, as applicable, and the other Party has failed, within the applicable periods set forth in Section 7.3, to agree upon a date for the first mediation session to take place within thirty (30) days after the appointment of such mediator or such longer period as the Parties may agree to in writing or (ii) the other Party has failed to comply with Section 7.3 in good faith with respect to commencement and engagement in arbitration. In such event, the first Party may commence and prosecute such arbitration unilaterally in accordance with the CPR Arbitration Procedure.

7.5    Conduct During Dispute Resolution Process. Unless otherwise agreed in writing, the Parties shall, and shall cause the other members of their respective Group to, continue to honor all commitments under this Agreement and each Ancillary Agreement to the extent required by such agreements during the course of dispute resolution pursuant to the provisions of this Article VII, unless such commitments are the specific subject of the Dispute at issue.

8.1    Further Assurances.

(a)    In addition to the actions specifically provided for elsewhere in this Agreement, each of the Parties shall use its reasonable best efforts, prior to, on and after the Effective Time, to take, or cause to be taken, all actions, and to do, or cause to be done, all things, reasonably necessary, proper or advisable under applicable Laws, regulations and agreements to consummate and make effective the transactions contemplated by this Agreement and the Ancillary Agreements.

(c)    On or prior to the Effective Time, Grace and GCP in their respective capacities as direct and indirect stockholders of the members of their Groups, shall each ratify any actions which are reasonably necessary or desirable to be taken by Grace, GCP or any of the members of their respective Groups, as the case may be, to effectuate the transactions contemplated by this Agreement and the Ancillary Agreements.

(d)    Grace and GCP, on their own behalf and on behalf of each of the members of their respective Groups, waive (and agree not to assert against any of the others) any claim or demand that any of them may have against any of the others for any Liabilities or other claims relating to or arising out of (i) the failure of any member of the GCP Group, on the one hand, or of any member of the Grace Group, on the other hand, to provide any notification or disclosure required under any state Environmental Law in connection with the Separation, the Distribution or the other transactions contemplated by this Agreement, including the transfer by any member of any Group to any member of the other Group of ownership or operational control of any Assets not previously owned or operated by such transferee or (ii) any inadequate, incorrect or incomplete notification or disclosure under any such state Environmental Law by the applicable transferor.

Each Party expressly adopts and confirms each such facsimile, stamp or mechanical signature (regardless of whether delivered in person, by mail, by courier, by facsimile or by email in portable document format (PDF)) made in its respective name as if it were a manual signature delivered in person, agrees that it will not assert that any such signature or delivery is not adequate to bind such Party to the same extent as if it were signed manually and delivered in person and agrees that, at the reasonable request of the other Parties at any time, it will as promptly as reasonably practicable cause this Agreement and each such Ancillary Agreement to be manually executed (any such execution to be as of the date of the initial date thereof) and delivered in person, by mail or by courier.

10.13    Waivers of Default. Waiver by a Party of any default by any other Party of any provision of this Agreement or any Ancillary Agreement shall not be deemed a waiver by the waiving Party of any subsequent or other default, nor shall it prejudice the rights of the other Party.
