Notes to Claims and Distribution Summary – Section 6.2 (c) Report

June 30, 2012

Pursuant to Section 2.3(a) of the GUC Trust Agreement, the GUC Trust was required to distribute, within thirty (30) days of the “GUC Trust Funding Date,” as such term is defined in the GUC Trust Agreement, any New GM Securities that would have been distributed on the next quarterly distribution date to holders of Resolved Allowed General Unsecured Claims and holders of Units as of the GUC Trust Funding Date (the “Section 2.3(a) Distribution”). The GUC Trust Funding Date was December 15, 2011 and, as such, the record date for the Section 2.3(a) Distribution was December 15, 2011. The Section 2.3(a) Distribution took place on or about January 13, 2012, and consisted solely of a distribution to holders of Resolved Allowed General Unsecured Claims, and holders of Allowed General Unsecured Claims who previously failed to fulfill informational requirements for distribution established in accordance with the GUC Trust Agreement, but successfully fulfilled such information requirements for the Section 2.3(a) Distribution. Because the amount of Excess GUC Trust Distributable Assets did not exceed the Distribution Threshold, no distribution to holders of Units was made in connection with the Section 2.3(a) Distribution.

The fourth quarter distribution was scheduled to take place on or as promptly as practicable following January 1, 2012, based upon the GUC Trust’s books and records as of December 31, 2011. However, as no Disputed General Unsecured Claims were allowed between the GUC Trust Funding Date and the December 31, 2011 record date for the fourth quarter distribution, no distribution was required to be made to holders of Resolved Allowed General Unsecured Claims. In addition, as the amount of Excess GUC Trust Distributable Assets did not exceed the Distribution Threshold, no distribution to holders of Units was required. As such, no quarterly distribution (other than the Section 2.3(a) Distribution referenced herein) was made during January 2012.

The fifth quarter distribution consisted solely of a distribution to holders of Resolved Allowed General Unsecured Claims, and holders of Allowed General Unsecured Claims who previously failed to fulfill informational requirements for distribution established in accordance with the GUC Trust Agreement, but successfully fulfilled such information requirements for the fifth quarter distribution. Because the amount of Excess GUC Trust Distributable Assets did not exceed the Distribution Threshold, no distribution to holders of Units was made in connection with the fifth quarter distribution.

The sixth quarter distribution is expected to take place in early August, 2012, and is expected to consist solely of a distribution to holders of Resolved Allowed General Unsecured Claims, and holders of Allowed General Unsecured Claims who previously failed to fulfill informational requirements for distribution established in accordance with the GUC Trust Agreement, but successfully fulfilled such information requirements for the fifth quarter distribution. Because the amount of Excess GUC Trust Distributable Assets did not exceed the Distribution Threshold, no distribution to holders of Units is anticipated in connection with the sixth quarter distribution.

Notes to Claims and Distribution Summary – Section 6.2 (c) Report

June 30, 2012

Units are issued at a ratio of one Unit for each $1,000 in amount of allowed general unsecured claim (such that if all Disputed General Unsecured Claims as of June 30, 2012 were subsequently allowed, the GUC Trust would issue approximately 35.98 million Units (inclusive of all Units previously distributed)).

Units in respect of general unsecured claims allowed as of the Initial Distribution were not issued (at that time, as evidenced on the GUC Trust’s books and records) until after the Effective Date. Hence, for purposes of this presentation only, Units outstanding as of the Effective Date is deemed to be zero. The 30,036,943 Units outstanding as of June 30, 2012 correlate to the $30,036,882,240 in allowed claims as of March 31, 2012. The Number of Units outstanding as of June 30, 2012 does not directly correspond to allowed claims as of March 31, 2012 on a 1 to 1,000 basis because 65 additional Units were issued due to rounding.

As of December 29, 2011, the GUC Trust Administrator reserved from distribution, in accordance with Sections 6.1(b), 6.1(c), and 6.1(d) of the GUC Trust Agreement and with the approval of the GUC Trust Monitor, Excess GUC Trust Distributable Assets consisting of 1,204,792 shares of New GM Common Stock and 1,095,265 warrants of each class of warrant in the aggregate (collectively the “Reserved Securities”) for the purposes of funding accrued and projected expenses of the GUC Trust, including Reporting and Transfer Costs.

Notes to Claims and Distribution Summary – Section 6.2 (c) Report

June 30, 2012

On March 8, 2012, the Bankruptcy Court entered an order (the “Liquidation Order”) authorizing the GUC Trust Administrator to liquidate a portion of the Reserved Securities, the proceeds of which (net of any applicable costs, fees, expenses and taxes payable in respect thereof) would approximate (x) $17,866,537 to satisfy GUC Trust administrative fees, costs and expenses incurred in 2011 and estimated for 2012 (“GUC Trust Administrative Costs”), and (y) $8,648,781 to satisfy Reporting and Transfer Costs incurred by the GUC Trust in 2011 and which could arise in 2012 (“GUC Trust Reporting Costs”). In addition, the Liquidation Order authorized the GUC Trust Administrator to liquidate New GM Securities which would generate proceeds approximating $13,714,000 (the “Avoidance Action Trust Cash”) to satisfy fees, costs and expenses of the Avoidance Action Trust estimated for 2012, 2013 and 2014 (the “Avoidance Action Trust Administrative Costs”). The Liquidation Order further provided that, following the receipt of a favorable ruling from the Internal Revenue Service (the “Favorable IRS Ruling”), the GUC Trust would be permitted to transfer the Avoidance Action Trust Cash to the Avoidance Action Trust.

Following the entry of the Liquidation Order and prior to March 31, 2012, the GUC Trust Administrator sold the following New GM Securities in accordance with the Liquidation Order: (i) 351,001 shares of New GM Common Stock and 319,092 warrants of each class of warrant for the aggregate proceeds of $17,868,184 in respect of the GUC Trust Administrative Costs; (ii) 169,912 shares of New GM Common Stock and 154,465 warrants of each class of warrant for the aggregate proceeds of $8,649,578 in respect of the GUC Trust Reporting Costs; and (iii) 269,422 shares of New GM Common Stock and 244,929 warrants of each class of warrant for the aggregate proceeds of $13,715,264 in respect of Avoidance Action Trust Administrative Costs. On April 24, 2012 the GUC Trust received the Favorable IRS Ruling, and on May 14, 2012 the GUC Trust transferred the Avoidance Action Trust Cash to the Avoidance Action Trust.

As of March 31, 2012, the GUC Trust Administrator reserved from distribution, in accordance with Sections 6.1(b), 6.1(c), and 6.1(e) of the GUC Trust Agreement and with the approval of the GUC Trust Monitor, additional Excess GUC Trust Distributable Assets primarily to address a contingent tax liability that would be incurred by the GUC Trust in the event that the value of the New GM Securities increases from the GUC Trust Funding Date to the time such New GM Securities are distributed, liquidated or otherwise disposed of by the GUC Trust (the “Taxes on Distribution Reserve”). On March 31, 2012, there was such a contingent tax liability estimated at approximately $108.6 million, as further described in Notes 2 and 3 of the Notes to the Financial Statements. As such, as of March 31, 2012, the aggregate Reserved Securities consisted of 2,688,527 shares of New GM Common Stock and 2,444,116 warrants of each class of warrants, which reflects both the Taxes on Distribution Reserve as well as New GM Securities reserved for the purposes of funding GUC Trust Administrative Costs and GUC Trust Reporting Costs projected for 2013 and 2014.

During the quarter ended June 30, 2012, additional Reserve Securities consisting of 637,438 additional shares of New GM Common Stock, 579,489 additional warrants of each class of warrants were set aside to fund projected GUC Trust Administrative Costs and GUC Trust Reporting Costs, primarily as a result of increases to reserves for expected costs of liquidation and the decrease in the fair market value of New GM Securities during the period. In addition, the GUC Trust Administrator reevaluates, on a quarterly basis, the amounts of New GM Securities included in the Taxes on Distribution Reserve. As a result of such review for the quarter ended June 30, 2012, the GUC Trust Administrator determined that it was necessary to include 2,069,306 additional shares of New GM Common Stock and 1,881,187 additional warrants of each class of warrants in the Taxes on Distribution Reserve. This increase was a result of a change in the calculation of securities to be set aside. The revised calculation uses the highest market price for the securities since December 15, 2011 (the date the New GM Securities were transferred to the Trust from MLC) in calculating the potential taxes on future gains from the disposition of New GM Securities rather than the market price for the securities at quarter end. For additional information, see the disclosure in the Form 8-K of the GUC Trust filed with the SEC on June 27, 2012.

As a result of such increases, as of June 30, 2012, the aggregate amounts of Reserved Securities consisted of 5,395,271 shares of New GM Common Stock and 4,904,792 warrants of each class of warrants, which reflects both the Taxes on Distribution Reserve as well as New GM Securities reserved for the purposes of funding GUC Trust Administrative Costs and GUC Trust Reporting Costs projected for 2013 and 2014.

June 30, 2012

Pursuant to Section 12.1 of the Plan, Law Debenture Trust Company of New York, in its capacity as claimant and as chair of the Official Committee of Unsecured Creditors of Motors Liquidation Company had requested a private letter ruling from the Internal Revenue Service (the “IRS”) which, if granted, would have eliminated the contingent tax liability to the extent arising from the distribution of New GM Securities. On May 7, 2012, the IRS informed representatives of the Official Committee of Unsecured Creditors of Motors Liquidation Company that it had made a final adverse determination with respect to the issuance of such private letter ruling, and that a favorable private letter ruling would not be forthcoming.

A copy of the Liquidation Order is available at the Motors Liquidation Company GUC Trust website at https://www.mlcguctrust.com/.

As described in footnote (1) above, no distributions to holders of Units were made in connection with the Section 2.3(a) Distribution (as defined in footnote (1) above), the fourth quarter distribution, or the fifth quarter distribution, as the amount of Excess GUC Trust Distributable Assets did not exceed the Distribution Threshold. Undistributed Excess GUC Trust Distributable Assets are reported in section H as Excess GUC Trust Distributable Assets reserved for distribution to holders of Units and will be held by the GUC Trust until the next calendar quarter for which the amount of Excess GUC Trust Distributable Assets exceeds the Distribution Threshold.
