As previously disclosed in a Current Report on Form 8-K filed on May 18, 2012 with the Securities and Exchange Commission (the “SEC”), on May 16, 2012, Hicks Acquisition Company II, Inc. (“HACII”) entered into an Equity Purchase Agreement (the “Equity Purchase Agreement”) with HH-HACII, L.P. (the “Sponsor”), Appleton Papers Inc. (“Appleton”) and Paperweight Development Corp. (“PDC”) and a Cross Purchase Agreement with PDC, pursuant to which, through a series of transactions, Appleton will become, subject to stockholder approval and other closing conditions, a non-wholly-owned subsidiary of HACII (the “Transaction”). On June 20, 2012, HACII entered into Amendment No. 1 to Equity Purchase Agreement (the “Amendment”) with the Sponsor, Appleton and PDC, which amends the Equity Purchase Agreement to (i) allow HACII to seek approval to amend the terms of HACII’s outstanding warrants (“Warrants”) to purchase shares of common stock of HACII (“Common Stock”), (ii) increase the amount of cash that must remain in the trust account established in connection with HACII’s initial public offering in order to satisfy a closing condition and (iii) give HACII the flexibility to seek approval of a charter amendment to extend HACII’s dissolution deadline by 60 days, if HACII so desires, to pursue the Transaction.

The Amendment permits HACII to seek the approval of the holders of 65% of its outstanding publicly-held Warrants to amend the warrant agreement that governs the Warrants to (i) make each Warrant (including the 15,000,000 Warrants issued in HACII’s initial public offering (the “Public Warrants”) and the 6,666,667 warrants purchased by the Sponsor (the “Sponsor Warrants”)) exercisable for one-half of one share of Common Stock (rather than one full share) at an exercise price of $6.00 per half-share (the “Warrant Adjustment”), (ii) allow each holder of Public Warrants to elect, for each such outstanding Public Warrant (in exchange for the reduction of shares for which the Public Warrants are exercisable), either (x) the right to receive $0.625 in cash or (y) the right to exercise the existing warrant for an additional 0.0879 of a share of Common Stock (the “Public Earnout Shares”), at an exercise price of $0.0001, in the event the last sales price of shares of Common Stock equals or exceeds $12.00 per share for 20 trading days out of 30 consecutive trading days on or prior to the fifth anniversary of the closing of the Transaction, subject to a limitation that the holders of no more than 4,550,626 Public Warrants may receive the Public Earnout Shares and (iii) cause the Sponsor to receive (in exchange for the reduction of shares for which the Sponsor Warrants are exercisable) an additional 0.0879 of a share of Common Stock per Sponsor Warrant (the “Sponsor Earnout Shares”), subject to forfeiture by the Sponsor in the event the last sales price of shares of Common Stock does not equal or exceed $12.00 per share for 20 trading days out of 30 consecutive trading days on or prior to the fifth anniversary of the closing of the Transaction (collectively, the “Warrant Amendment Proposal”). The Sponsor Earnout Shares are effectively the same as the Public Earnout Shares, as the economic value of both the Sponsor Earnout Shares and the Public Earnout Shares are triggered by the same target stock price. The effect of the Warrant Adjustment will be to reduce the number of shares of Common Stock issuable upon exercise of the Warrants by half (excluding the Public Earnout Shares).

In addition, the Amendment (i) amends a closing condition that previously required there to be at least $75.0 million in cash held in trust, after giving effect to any redemptions and permitted repurchases of Common Stock in connection with the stockholder vote to approve the Transaction, to increase such amount to $82.0 million and (ii) gives HACII the ability to seek to amend its charter (with approval of holders of 65% of HACII’s outstanding Common Stock) to extend HACII’s dissolution deadline by 60 days, if HACII so desires, for purposes of consummating the Transaction.
