ADDITIONAL DISCLOSURE
 
The following additional disclosure supplements disclosure contained in the joint proxy statement/prospectus that was declared effective on May 23, 2011 and was mailed on or about May 27, 2011 to stockholders of Holly Corporation (“Holly”) and shareholders of Frontier Oil Corporation (“Frontier”) in connection with the Agreement and Plan of Merger, dated as of February 21, 2011, by and among Holly, North Acquisition, Inc. and Frontier.  The additional disclosure is incorporated by reference into, and should be read in conjunction with, the joint proxy statement/prospectus, which should be read in its entirety. Unless otherwise defined below, terms used below shall have the meanings set forth in the joint proxy statement/prospectus.
 

 
LITIGATION RELATING TO THE MERGER
 
As previously disclosed in the joint proxy statement/prospectus under the heading “—Litigation Related to the Merger,” twelve substantially similar shareholder lawsuits styled as class actions were filed by alleged Frontier shareholders challenging the merger and naming as defendants Frontier, its board of directors and, in certain instances, Holly and Merger Sub as aiders and abettors. To date, such shareholder actions have been filed in Harris County, Texas, Laramie County, Wyoming, the U.S. District Court for the Northern District of Texas, and the U.S. District Court for the Southern District of Texas. On March 25, 2011, the lawsuits pending in the District Court of Harris County, Texas, were consolidated under the style In re: Frontier Oil Corp., Cause No. 2011-11451.

These lawsuits generally allege that (1) the consideration to be received by Frontier’s shareholders in the merger is inadequate, (2) the Frontier directors breached their fiduciary duties by, among other things, approving the merger at an inadequate price under circumstances involving certain alleged conflicts of interest, (3) the merger agreement includes preclusive deal protection provisions, and (4) Frontier, and in some cases Holly and Merger Sub, aided and abetted Frontier’s board of directors in breaching its fiduciary duties to Frontier’s shareholders.  In addition to these claims, the three lawsuits filed in the U.S. District Court for the Northern District of Texas and the U.S. District Court for the Southern District of Texas allege that the defendants violated Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 by making untrue statements of material fact and omitting to state material facts necessary to make the statements that were made not misleading in the joint proxy statement/prospectus. The shareholder actions seek various remedies, including enjoining the transaction from being consummated in accordance with its agreed-upon terms, compensatory damages, and costs and disbursements relating to the lawsuits.

On June 17, 2011, the defendants reached an agreement-in-principle with the plaintiffs in: In re: Frontier Oil Corp., to settle the eight consolidated class action lawsuits pending in Harris County, Texas.  No agreement has been reached with plaintiffs in the other cases who may attempt to continue to pursue their claims. In connection with the proposed settlement, certain additional disclosures are being made to Frontier’s shareholders, which are contained in this supplement to the joint proxy statement/prospectus. The parties contemplate that the agreement-in-principle will be documented by the parties, that the written agreement will contain customary provisions and further agree that approval of the settlement must, and will, be sought from the court following notice to the shareholders of Frontier and consummation of the merger. In connection with the approval of the settlement, a hearing will be scheduled at which the court will consider the fairness, reasonableness and adequacy of the settlement which, if finally approved by the court, will resolve all of the claims that were or could have been brought in the actions being settled and the other actions, including all claims relating to the merger, the merger agreement and any disclosures made in connection therewith. The parties contemplate that the settlement will provide individual shareholders with the right to opt out of the settlement before the hearing and, if the number of shares held by individual shareholders who opt out reaches a certain percentage, the settlement will further provide defendants with the right to withdraw from the settlement.  In addition, in connection with the settlement, the parties contemplate that plaintiff’s counsel will petition the court for an award of attorneys’ fees and expenses to be paid by the defendants. We cannot be certain that the parties will ultimately enter into a written settlement agreement or that the court will approve the settlement even if the parties were to enter into such an agreement. If the court does not approve the settlement or if sufficient individual shareholders opt out and defendants elect to withdraw from the settlement, the proposed settlement as contemplated by the agreement-in-principle may be modified or terminated.

The settlement will not affect the amount of merger consideration to be paid in the merger.

Background of the Merger (beginning on page 35)

The following shall be added as the last sentence of the paragraph beginning, “Beginning in late December 2010…” on page 37:

Mr. Jennings and the other board members believed that it was in the interests of Frontier shareholders to structure any potential transaction with Holly as a stock transaction and a true merger of equals in light of the benefits of providing Frontier shareholders a continuing equity interest in the combined company, the comparable levels of complexity and performance of the two companies over time, the objective of conserving cash and maintaining prudent debt levels for the combined company, and the desire to combine the strengths of both companies.

The following shall be substituted for the first sentence of the paragraph beginning, “On December 9, 2010, Mr. Clifton …” on page 36:

On December 9, 2010, Mr. Clifton met with Mr. Jennings in Dallas. At this meeting, Messrs. Clifton and Jennings discussed their views regarding the potential strategic and financial benefits of a merger between Holly and Frontier, based solely on publicly available information. In addition, they discussed their views on the industry’s prospects, including continuing volatility in crack spreads and the industry trend toward greater  scale and complexity of operations.  They also discussed the economy as a whole and the potential benefits of a business combination in terms of size and diversification.

The following shall be substituted for the paragraph beginning, “On December 17, 2010, Messrs. Clifton and Jennings …” on page 37:

On December 17, 2010, Messrs. Clifton and Jennings had a follow-up meeting in Dallas to continue discussions. Each outlined his views on what roles their respective executive management teams might have in the combined company and agreed on the need for management continuity in connection with integrating the two companies. In general terms, they discussed ways to combine the skills of each of  the various executive officers of Holly and Frontier to benefit the combined company going forward, including what their own roles might be and the roles of other executive officers.  They discussed the benefits of having a separate executive chairman and chief executive officer who would combine leadership of Holly and Frontier and provide continuity of management for the combined company. Both agreed that a business combination between the two companies remained a mutually desirable prospect as a merger of equals at market, such as a 30-day average closing price of the common stock of the two companies. Mr. Jennings noted financing-related benefits that might come from a stronger combined balance sheet and ability to access more trade credit with suppliers.

The following shall be substituted for the paragraph beginning, “On February 4, 2011, the Frontier board of directors …” on page 39:

On February 4, 2011, the Frontier board of directors held a special meeting in Houston, together with members of Frontier’s management and legal and financial advisors. Mr. Jennings provided an overview of the potential transaction, to be structured as a merger of equals, and the progress of the transaction to date. Andrews Kurth advised the board regarding its fiduciary duties in connection with considering a possible business combination, and the importance of board review and deliberations. Andrews Kurth also presented an overview of the draft merger agreement as proposed by Holly, which had been previously distributed to the board. The board discussed the terms to be negotiated in the merger agreement, including the non-solicitation provisions and size of the break-up fee, and while no specific terms or amounts were discussed, the board noted that those provisions should be reciprocal and customary. Frontier’s financial advisors discussed with the board certain financial aspects relating to the potential merger.

The following shall be added as the last sentence of the paragraph beginning, “On January 14, 2011…” on page 38:

The merger was viewed at all times by both Holly and Frontier as a merger of equals.  Accordingly, during the course of negotiations, Holly and Frontier discussed that the exchange ratio would largely be based on the relative trading prices of the common stock of Holly and Frontier, including the current trading price, the five-day average closing price, and the 30-day average closing price, all of which would necessarily be constantly changing as the parties negotiated the merger agreement.
