Exhibit CRevised Section 1.04 of the Master Agreement

1.04    Balance Sheet Adjustment.

(a)Estimate Statement. No less than 10 Business Days prior to the Closing Date, each of Oracle and Watson will provide to each other (in each case, with a copy to Iris) a statement (each individually, an “Estimate Statement”) with such Parent’s good faith estimate of the Closing Working Capital of Oracle and Closing Working Capital of Sky, respectively (the “Estimated Oracle Closing Working Capital” and the “Estimated Sky Closing Working Capital,” respectively). Each Estimate Statement will be prepared by such Parent on an unaudited basis, and all calculations thereon will utilize the same presentation format, apply the same accounting principles, practices, methodologies and policies as are utilized in the Financial Statements of Oracle or Sky, as the case may be (the “Accounting Principles”), and will be adjusted for any mutually agreed and commercially reasonable adjustments (with the Parties agreeing to negotiate in good faith) related to material differences between the Parents’ Accounting Principles (which may include changes to Schedule 1.04.1 and Schedule 1.04.2). Following the delivery of the Estimate Statements, the Parties will work together, including making arrangements for the relevant Parent (or a Subsidiary thereof, including the applicable Shareholder) (such Person, the “Retaining Person”) to retain the benefits and burdens of ownership with respect to an identified dollar amount of receivables or payables (and this may include retaining ownership of such receivables or payables for Tax purposes or otherwise), to ensure that the working capital balances as estimated above that are to be contributed as part of the Contemplated Transactions equal relative contributions of 44% Oracle, 44% Watson, and 12% Iris. Any receivable or payable balance retained by a Retaining Person pursuant to this Section 1.04(a) shall be treated as never having been transferred to Newco (whether directly or indirectly via a Contributed Subsidiary) and, to the extent that Sky comes to hold (directly or indirectly) nominal title to any such receivable or payable, Sky shall be deemed to have acted as the agent of the Retaining Person with respect to such receivable or payable and therefore shall not report the taxable income associated with such receivable or deduct the amount of such payable but instead shall provide to the Parent information to permit the Retaining Person to report such amount on its own tax return. Any amounts received or paid by Sky with respect to such receivables or payables shall be first allocated by Sky to the retained amounts until amounts to be received have been collected and transferred to the applicable Retaining Person or all amounts required to be paid have been paid by Sky, as the case may be.

(b)Final Statement. No later than 60 days after the Closing Date, Oracle and Watson will cause to be prepared and delivered to each other Parent a statement of the Closing Working Capital of Oracle and Closing Working Capital of Sky, respectively (each, a “Final Statement,” and such Closing Working Capital amounts, as finally determined pursuant to this Section 1.04, with respect to Oracle, the “Final Oracle

Closing Working Capital”, with respect to Sky, the “Final Sky Closing Working Capital” and, each individually, a “Final Closing Working Capital Amount”). Each Final Statement will be prepared by such Parent on an unaudited basis and apply the applicable Accounting Principles and adjustments, if any, agreed under Section 1.04(a). If either Oracle, on the one hand, or Watson and Iris, on the other hand, disagree with the other side’s (it being understood that references to “side” in this Section 1.04 will be deemed to be to Oracle, on the one hand, or Watson and Iris, on the other hand) calculation of any of the items in such other side’s Final Statement as delivered, the disagreeing side may, within 60 days after delivery of such Final Statement by the other side, deliver a written notice to such other Parent(s) that specifies in reasonable detail the items or amounts disputed, the basis therefor and the value proposed to be assigned to such items or amounts (an “Objection Notice”). A side will be deemed to have agreed with all items and amounts for which no Objection Notice is delivered within such 60-day period. If an Objection Notice is delivered by either side, the Parents will, during the 60 days following delivery of the Objection Notice, promptly begin discussions in an attempt to agree on a calculation of the disputed Closing Working Capital amount. For purposes of complying with the terms set forth in this Section 1.04, each Parent will cooperate with and make available to the other Parents and their representatives as promptly as practicable in consideration of the time requirements set forth in this Section 1.04 all information, records, data and working papers, and will permit access to its facilities and personnel, as may reasonably be requested in connection with the preparation and analysis of the calculations of a Closing Working Capital amount, including with respect to any valuations or calculations to be performed in connection therewith. The Parents will jointly prepare a statement as to those items or amounts in dispute that they have agreed to and the resolution thereof. If the Parents are unable to agree upon any calculation of a Closing Working Capital amount, then Section 1.04(c) will apply.

(c)Dispute.

(i)If the Parents are unable to agree upon the calculation of any Closing Working Capital amount within the 60-day period following the delivery of an Objection Notice by a Parent, then the Parents jointly will engage a mutually acceptable accounting firm of nationally recognized reputation (the “Accounting Firm”) to resolve those items or amounts that remain in dispute. Promptly, but in no event later than 60 days following its engagement, the Accounting Firm will determine, based solely on written submissions by Oracle, on the one hand, and Watson and Iris, on the other hand, only those issues in dispute and will render a written report as to the resolution of the dispute and the resulting computation of the disputed Closing Working Capital amount. In resolving any disputed item, the Accounting Firm will consider only those items or amounts in the applicable Final Statement as to which the Parents continue to disagree, and the Accounting Firm will be bound by the provisions of this Section 1.04 and must assign a value to each such item equal to the value for such item claimed by Oracle, on the one hand, or Watson and Iris, on the other

hand. The Parents will bear the fees and expenses of the Accounting Firm in the following proportions: 44% for Oracle, 44% for Watson, and 12% for Iris.

(ii)Each Parent will cooperate with the Accounting Firm in its valuation process and will share any relevant materials it has regarding valuation with the Accounting Firm and the other Parents, and each Parent will cooperate in good faith to cause the Accounting Firm to deliver to the Parents within 60 Business Day of its engagement the Accounting Firm’s determination of the value of each disputed item in the computation of Closing Working Capital. The values determined in accordance with this Section 1.04(c) will be final and binding for the purposes of this Agreement.

(d)Adjustment Payments.

(i)If the Final Oracle Closing Working Capital, as finally determined pursuant to this Section 1.04, is greater than the Estimated Oracle Closing Working Capital (as adjusted by Section 1.04(a)), then Sky will, within 5 Business Days after such final determination, pay to Oracle Mills the amount of such excess by the wire transfer of immediately available funds to the bank account designated in writing by Oracle. Any amounts paid pursuant to this Section 1.04(d)(i) shall deemed to have been paid from the collection of receivables that shall have been deemed to have been retained by the applicable Shareholder, and not from the proceeds of any borrowing by Newco or any Subsidiary of Newco.

(ii)If the Final Oracle Closing Working Capital, as finally determined pursuant to this Section 1.04, is less than the Estimated Oracle Closing Working Capital as adjusted by Section 1.04(a), then Oracle will, within 5 Business Days after such final determination, cause Oracle Mills to pay to Sky the amount of such shortfall by the wire transfer of immediately available funds to the bank account designated in writing by Sky.

(iii)If Watson’s proportionate share of Final Sky Closing Working Capital, as finally determined pursuant to this Section 1.04, is greater than Watson’s proportionate share of the Estimated Sky Closing Working Capital (as adjusted by Section 1.04(a)), then Sky will, within 5 Business Days after such final determination, pay to Watson the amount of such excess by the wire transfer of immediately available funds to the bank account designated in writing by Watson. Any amounts paid pursuant to this Section 1.04(d)(iii) shall deemed to have been paid from the collection of receivables that shall have been deemed to have been retained by the applicable Shareholder, and not from the proceeds of any borrowing by Newco or any Subsidiary of Newco. For purposes of this Section 1.04(d), Watson’s “proportionate share” of any amount will be determined by reference to Watson’s respective ownership interest in Sky and Sky Canada immediately prior to the Closing.

(iv)If Watson’s proportionate share of the Final Sky Closing Working Capital, as finally determined pursuant to this Section 1.04, is less than Watson’s proportionate share of the Estimated Sky Closing Working Capital (as adjusted by Section 1.04(a)), then Watson will, within 5 Business Days after such final determination, pay to Sky the amount of such shortfall by the wire transfer of immediately available funds to the bank account designated in writing by Sky.

(v)If Iris’ proportionate share of Final Sky Closing Working Capital, as finally determined pursuant to this Section 1.04, is greater than Iris’ proportionate share of the Estimated Sky Closing Working Capital (as adjusted by Section 1.04(a)), then Sky will, within 5 Business Days after such final determination, pay to Iris the amount of such excess by the wire transfer of immediately available funds to the bank account designated in writing by Iris. Any amounts paid pursuant to this Section 1.04(d)(v) shall deemed to have been paid from the collection of receivables that shall have been deemed to have been retained by the applicable Shareholder, and not from the proceeds of any borrowing by Newco or any Subsidiary of Newco. For purposes of this Section 1.04(d), Iris’ “proportionate share” of any amount will be determined by reference to Iris’ respective ownership interest in Sky and Sky Canada immediately prior to the Closing.

(vi)If Iris’ proportionate share of the Final Sky Closing Working Capital, as finally determined pursuant to this Section 1.04, is less than Iris’ proportionate share of the Estimated Sky Closing Working Capital (as adjusted by Section 1.04(a)), then Iris will, within 5 Business Days after such final determination, pay to Sky the amount of such shortfall by the wire transfer of immediately available funds to the bank account designated in writing by Sky.

(vii)Tax Treatment of Adjustment Payments. Notwithstanding anything to the contrary set forth in this Agreement, (i) any payment made by a Parent or its Subsidiary pursuant to Section 1.04(d) shall not be treated as a separate contribution to Newco (or its Subsidiaries), but shall be considered part of the Conveyances or contributions described in Section 5.08(ii) through 5.08(vi) and shall have been included in the contributing Shareholder’s initial Capital Account, and (ii) the amount of any adjustment in Section 1.04(d) that is treated as a return of excess contributions shall have been netted against the relevant Shareholder’s initial contribution of Closing Working Capital for purposes of determining that Shareholder’s initial Capital Account pursuant to the applicable sections of the Alliance Agreement. Consistent with the provisions of the preceding sentence and of Section 1.04(a), if excess Closing Working Capital is returned to a Parent or its Subsidiary (because the Parent or Subsidiary transferred excess Closing Working Capital to Newco), such excess amount shall be treated as having been erroneously transferred to Newco (or its Subsidiaries) as part of the assets or liabilities held by a Contributed Subsidiary, and Sky shall be deemed to have acted as the agent of such Parent or its Subsidiary with

respect to such excess amount and therefore shall not report the taxable income associated with such Closing Working Capital but instead shall provide to the Parent information to permit such Parent or its Subsidiary to report such amount on its own tax return.
