The Amendment has been incorporated herein by reference to provide information regarding its terms and is not intended to modify or supplement any factual disclosures about Arch, Merger Sub or ICG in any public reports filed with the U.S. Securities and Exchange Commission (the “SEC”). In particular, the assertions embodied in the representations, warranties and covenants contained in the Merger Agreement, as amended, were made only for the purposes of such agreement, were solely for the benefit of the parties to the Merger Agreement, and may be subject to limitations agreed upon by the contracting parties, including being qualified by information in confidential disclosure schedules provided by ICG to Arch in connection with the signing of the Merger Agreement. These disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Merger Agreement. Moreover, the representations and warranties in the Merger Agreement were used for the purpose of allocating risk between Arch, Merger Sub and ICG, rather than establishing matters of fact. Accordingly, the representations and warranties in the Merger Agreement may not constitute the actual state of facts about Arch, Merger Sub or ICG. The representations and warranties set forth in the Merger Agreement may also be subject to a contractual standard of materiality different from that generally applicable to investors under federal securities laws.

In connection with the transactions described in Item 83.01 ~~Other~~below, ~~Events~~the Company entered into a Second Supplemental Indenture dated as of June 15, 2011 (the “2012 Notes Second Supplemental Indenture”) with The Bank of New York Mellon Trust Company, N.A., as trustee, related to the Indenture dated as of July 31, 2007 (the “2012 Notes Original Indenture”), as amended and supplemented by the First Supplemental Indenture dated as of December 3, 2009 (the “2012 Notes First Supplemental Indenture” and, together with the 2012 Notes Original Indenture, and the 2012 Notes Second Supplemental Indenture, the “2012 Notes Indenture”), relating to the Company’s outstanding 9.00% Convertible Senior Notes due 2012 (the “2012 Notes”).

Item 2.04		Triggering Events That Accelerate or Increase a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement.

Make-Whole Fundamental Change Relating to 4.00% Convertible Senior Notes

Upon the consummation of the Merger, a make-whole fundamental change relating to the 2017 Notes occurred and the conversion rate applicable to 2017 Notes that are surrendered for conversion during the period (the “2017 Notes Make-Whole Conversion Period”) from, and including, June 15, 2011, the effective date of the make-whole fundamental change relating to the Merger, to, and including, the 2017 Notes Fundamental Change Repurchase Date (as defined below), was increased by 7.0006 shares of Common Stock per $1,000 principal amount of 2017 Notes. Accordingly, upon surrender of 2017 Notes for conversion following the Merger in connection with the make-whole fundamental change resulting from the Merger, the Company’s conversion obligation during the 2017 Notes Make-Whole Conversion Period will be calculated based solely on the Merger Consideration (as defined below in Item 3.01) received by the Company’s stockholders in the Merger and shall be deemed to be an amount equal to, per $1,000 principal amount of converted 2017 Notes, the applicable conversion rate of 179.0880 shares of Common Stock per $1,000 principal amount of 2017 Notes, multiplied by the Merger Consideration (as defined below). Based on the above, holders of 2017 Notes surrendered for conversion during the 2017 Notes Make-Whole Conversion Period will be entitled to receive, at settlement, $2,614.6848 in cash for each $1,000 principal amount of 2017 Notes surrendered for conversion.

In addition, the consummation of the Offer described below under Item 3.01 constituted a “Fundamental Change” under the 2017 Notes Indenture. As a result, holders of 2017 Notes will have the right to require the Company to repurchase all or a portion of such holder’s 2017 Notes, at a price, payable in cash, equal to 100% of the principal amount of the 2017 Notes (or portions thereof) to be so repurchased on a date selected by the Company (the “2017 Notes Fundamental Change Repurchase Date”), which shall be no later than 35 days, nor earlier than 20 days, after the date the applicable fundamental change notice is mailed. The fundamental change notice relating to the 2017 Notes is required to be mailed by the Company no later than July 13, 2011. Accordingly, the 2017 Notes Fundamental Change Repurchase Date relating to the consummation of the Offer, which will be

Plaintiffs seek relief that includes, inter alia, an injunction prohibiting the proposed transaction, an accounting, and costs and disbursements of the action, including attorneys’ fees and experts’ fees.

The fundamental change notice relating to the 2012 Notes is required to be mailed by the Company no later than July 13, 2011.

~~Innisfree~~ Holders ~~M&A~~of 2012 Notes surrendered for conversion as and when permitted by the 2012 Notes ~~Incorporated~~Indenture after the expiration of the 2012 Notes Make-Whole Conversion Period will be entitled to receive, at settlement, $2,391.67856 in cash for each $1,000 principal amount of 2012 Notes surrendered for conversion.

~~Banks~~ Pursuant to the Merger Agreement and ~~brokers~~upon ~~may~~the ~~call~~terms ~~collect~~and conditions thereof, on May 16, 2011, Merger Sub commenced a tender offer (~~212~~the “Offer”) ~~750-5833~~ to acquire all of the outstanding shares of the Company’s Common Stock (the “Shares”), for $14.60 per share in cash, without interest and subject to applicable withholding taxes (the “Offer Price” or the “Merger Consideration”).

~~Arch~~ On ~~Coal~~June 14, ~~Inc~~2011, Parent announced the completion of the Offer which expired at 8:00 a.m., New York City time, on June 14, 2011. According to Computershare Trust Company, N.A., the depositary for the Offer, as of the Offer expiration, a total of approximately 188,388,837 Shares (including 16,672,951 Shares subject to guaranteed delivery procedures) were validly tendered and not

properly withdrawn, representing approximately 92.3% of the Shares then outstanding on a non-fully diluted basis and approximately 89.5% Shares on a fully diluted basis (as determined pursuant to the Merger Agreement). On June 14, 2011, Parent announced that Merger Sub had accepted for payment in accordance with the terms of the Offer all Shares that were validly tendered and not withdrawn prior to the expiration of the Offer.

Also on June 14, 2011, pursuant to the terms of the Merger Agreement, Merger Sub exercised its top-up option (the “Top-Up Option”) to purchase directly from the Company an aggregate number of additional shares of Common Stock that, when added to the number of Shares already owned immediately prior to the exercise of such option (which for these purposes does not include Shares that were tendered subject to guaranteed delivery procedures), results in Merger Sub, Parent and Parent’s wholly owned subsidiaries owning one Share more than 90% of the then outstanding Shares. Pursuant to the exercise of the Top-Up Option, Merger Sub purchased directly from the Company a total of 120,441,395 newly issued shares of Common Stock (the “Top-Up Option Shares”) at the Offer Price. Such Top-Up Option Shares, combined with the Shares already owned by Merger Sub, Parent and Parent’s wholly owned subsidiaries, represented one Share more than 90% of the then outstanding Shares. Merger Sub paid the purchase price for the Top-Up Option Shares in cash in the amount of $1,204,413.95 and the remainder by delivery of a promissory note.

Following the exercise of the Top-Up Option, Merger Sub effected a “short form” merger under Delaware law of Merger Sub with and into the Company, as further described below, without the need for a meeting of the Company’s stockholders.

Effective as of 12:01 a.m., New York City time, on June 15, 2011, Merger Sub was merged with and into the Company pursuant to the terms of the Merger Agreement, with the Company continuing as the surviving corporation and as a wholly owned subsidiary of Parent. At the effective time of the Merger, each remaining issued and outstanding Share not tendered in the Offer (other than any Shares held by Parent, the Company (in its treasury) or any of their wholly owned subsidiaries, including Merger Sub) was converted into the right to (a) receive the Merger Consideration or (b) seek appraisal of such Shares under Delaware law.

On June 15, 2011, in connection with the Merger, the Company notified the New York Stock Exchange (the “NYSE”) of its intent to remove its Common Stock from listing on the NYSE and requested that the NYSE file a delisting application with the Securities and Exchange Commission (“SEC”) to delist and deregister its common stock. On June 16, 2011, the NYSE filed with the SEC a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on Form 25 to delist and deregister the Common Stock. The Company intends to file with the SEC a certification on Form 15 under the Exchange Act, requesting the deregistration of the Common Stock and the suspension of the Company’s reporting obligations under Sections 13 and 15(d) of the Exchange Act.


Item 3.02		Unregistered Sales of Equity Securities.

The disclosure under Item 3.01 is incorporated herein by reference. The Top-Up Option Shares were issued without registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon the exemption from registration set forth in Section 4(2) of the Securities Act for transactions not involving a public offering.


Item 3.03		Material Modification to Rights of Security Holders.

At the effective time of the Merger, each remaining issued and outstanding Share not tendered in the Offer (other than any Shares held by Parent, the Company (in its treasury), or any of their wholly owned subsidiaries, including Merger Sub) was converted into the right to (i) receive the Merger Consideration or (ii) seek appraisal of such Shares under Delaware law.

On June 14, 2011, in connection with the Merger, the Company provided notice of redemption to the holders of the Company’s outstanding 9.125% Senior Secured Second-Priority Notes due 2018 (the “2018 Notes”), and deposited with the trustee of the 2018 Notes, sufficient funds to pay those holders the redemption price and all accrued and unpaid interest with respect to the 2018 Notes (the “2018 Notes Deposited Funds”). Upon receipt of the 2018 Notes Deposited Funds, the trustee issued an acknowledgement that all of the Company’s obligations pursuant to the indenture governing the 2018 Notes were satisfied and discharged.

The disclosure under Item 1.01 is incorporated herein by reference.
