         On May 20, 2003, the Company issued the following press release:

              JOINT NEWS
              RELEASE

              FOR IMMEDIATE RELEASE

              FRONTIER OIL AND HOLLY CORPORATION ANNOUNCE TERMINATION OF THE
              HART-SCOTT-RODINO WAITING PERIOD FOR PENDING MERGER

                  Dallas, Texas, May 20, 2003 - Frontier Oil Corporation (NYSE -
              FTO) and Holly Corporation (AMEX - HOC) announced today that the
              waiting period under the Hart-Scott-Rodino Antitrust Improvements
              Act has expired, satisfying one of the conditions to the
              completion of the pending merger of Frontier and Holly. In
              addition, the Federal Trade Commission approved Holly's pending
              acquisition from ConocoPhillips of the Woods Cross refinery and
              related assets located near Salt Lake City, Utah. The Woods Cross
              refinery acquisition is expected to close on June 1, 2003, which
              will satisfy another condition to the completion of the pending
              merger of Frontier and Holly.

                  Completion of the pending merger of the two companies remains
              subject to, among other things, both companies receiving
              stockholder approval. Front Range Himalaya Corporation, which will
              be the parent company and renamed "Frontier Oil Corporation" after
              the merger, has filed a Form S-4 Registration Statement (which
              includes the joint



              preliminary proxy statement of Frontier and Holly) relating to the
              proposed merger with the Securities and Exchange Commission.

                  Frontier, headquartered in Houston, Texas, operates a 110,000
              bpd refinery located in El Dorado, Kansas and a 46,000 bpd
              refinery located in Cheyenne, Wyoming. Holly, headquartered in
              Dallas, Texas, operates a 60,000 bpd refinery located in Artesia,
              New Mexico that is being expanded to 75,000 bpd and a 7,500 bpd
              refinery in Great Falls, Montana. Holly also operates
              approximately 2,000 miles of crude oil and refined product
              pipelines in the west Texas and New Mexico region, Permian Basin
              crude gathering operations and refined product terminals.

              Investor Notices

                  This press release includes "forward-looking statements" as
              defined by the Securities and Exchange Commission. Such statements
              are those concerning the contemplated transaction and strategic
              plans, expectations and objectives for future operations. All
              statements, other than statements of historical facts, included in
              this press release that address activities, events or developments
              that the companies expect, believe or anticipate will or may occur
              in the future are forward-looking statements. This includes
              completion of the proposed transaction, realization of expected
              synergies from the transaction, future financial performance,
              future equity issuance and other matters. These statements are
              based on certain assumptions made by the companies based on their
              experience and perception of historical trends, current
              conditions, expected future developments and other factors they
              believe are appropriate in the circumstances. Such statements are
              subject to a number of assumptions, risks and uncertainties, many
              of which are beyond the control of the companies. Investors are
              cautioned that any such statements are not guarantees of future
              performance and that actual results or developments may differ
              materially from those projected in the forward-looking statements.



                  Frontier and Holly have filed a preliminary joint proxy
              statement/prospectus and other documents regarding the proposed
              merger described in this press release with the Securities and
              Exchange Commission as part of a Registration Statement on Form
              S-4 filed by Front Range Himalaya Corporation. Investors and
              security holders are urged to read the preliminary joint proxy
              statement/prospectus included in such Registration Statement
              because it contains important information about Frontier and Holly
              and the proposed transaction. A definitive joint proxy
              statement/prospectus will be sent to security holders of Frontier
              and Holly seeking their approval of the transaction. Investors and
              security holders may obtain a free copy of the definitive joint
              proxy statement/prospectus (when available) and other documents
              filed by Frontier and Holly with the SEC at the SEC's web site at
              www.sec.gov. The definitive joint proxy statement/prospectus and
              other relevant documents may also be obtained free of cost by

              1600, Dallas, Texas 75201.

                   Frontier and Holly and their respective directors and
              executive officers may be deemed to be participants in the
              solicitation of proxies from the shareholders of Frontier and
              Holly in connection with the merger. Information about Frontier
              and Holly and their respective directors and officers can be found
              in Proxy Statements, Annual Reports on Form 10-K and Quarterly
              Reports on Form 10-Q filed by Frontier and Holly with the SEC.
              Additional information regarding the interests of those persons
              may be obtained by reading the preliminary joint proxy
              statement/prospectus and the definitive joint proxy
              statement/prospectus when it becomes available.

       This Current Report on Form 8-K contains certain "forward-looking
statements" within the meaning of the U.S. Private Securities Litigation Reform
Act of 1995. All statements, other than statements of historical facts included
in this Form 8-K, are forward-looking statements. Such statements are subject to
risks and uncertainties,



including but not limited to risks and uncertainties with respect to the actions
of actual or potential competitive suppliers of refined petroleum products in
the Company's markets, the demand for and supply of crude oil and refined
products, the spread between market prices for refined products and market
prices for crude oil, the possibility of constraints on the transportation of
refined products, the possibility of inefficiencies or shutdowns in refinery
operations or pipelines, effects of governmental regulations and policies, the
availability and cost of financing to the Company, the effectiveness of the
Company's capital investments and marketing strategies, the Company's efficiency
in carrying out construction projects, the successful acquisition and
integration of the Woods Cross refinery, the completion of the proposed
transaction with Frontier Oil Corporation, the possibility of terrorist attacks
and the consequences of any such attacks, and general economic conditions.
Although the Company believes that the expectations reflected by such
forward-looking statements are reasonable based on information currently
available to the Company, no assurances can be given that such expectations will
prove to have been correct. This summary discussion of risks and uncertainties
that may cause actual results to differ from those indicated in forward-looking
statements should be read in conjunction with the discussion under the heading
"Additional Factors That May Affect Future Results" included in Item 7 of the
Company's Annual Report on Form 10-K for the fiscal year ended July 31, 2002,
and the discussion under the heading "Additional Factors That May Affect Future
Results" included in Item 2 of Part I of the Company's Quarterly Report on Form
10-Q for the quarter ended January 31, 2003. All forward-looking statements

forward-looking statements attributable to the Company or persons acting on its
behalf are expressly qualified in their entirety by the cautionary statements
set forth above.
