This Amendment No. 13 to the Schedule 14D-1 relates to a tender offer by ECO Acquisition Corporation (the "Purchaser"), a Delaware corporation and a wholly owned subsidiary of Eli Lilly and Company, an Indiana corporation ("Parent"), to purchase all outstanding shares of common stock, par value $2.00 per share and the associated Rights (as defined in the Offer to Purchase) (collectively, the "Shares"), of McKesson Corporation (the "Company"), a Delaware corporation, at a purchase price of $76.00 per Share, net to the seller in cash, without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated July 15, 1994 (the "Offer to Purchase"), and the related Letter of Transmittal (which together constitute the "Offer"), copies of which were attached as Exhibits (a)(1) and (a)(2), respectively, to the Schedule 14D- 1 filed with the Securities and Exchange Commission on July 15, 1994 as amended by Amendment Nos. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 thereto dated July 27, 1994, August 10, 1994, September 7, 1994, September 21, 1994, October 11, 1994, October 13, 1994, October 14, 1994, October 24, 1994, October 26, 1994, November 4, 1994, November 7, 1994 and November 10, 1994, respectively (collectively, the "Schedule 14D-1"). The purpose of this Amendment No. 13 is to amend and supplement Items 6, 10 and 11 of the Schedule 14D-1 as described below. Pursuant to Instruction F of Schedule 14D-1, this statement is submitted in satisfaction of the reporting obligation of Purchaser under Section 13(d) of the Securities Exchange Act of 1934, as amended. ITEM 6. INTEREST IN SECURITIES OF THE SUBJECT COMPANY At 5:00 p.m., New York City Time, on November 21, 1994, the Offer expired. Based on information provided by the Depositary, a total of 42,640,622 Shares (or approximately 94.9% of the Shares outstanding) were validly tendered and not withdrawn pursuant to the Offer, including 2,933,458 Shares (approximately 6.5% of the Shares outstanding) tendered pursuant to notices of guaranteed delivery. The Purchaser has accepted for payment all such Shares at the purchase price of $76.00 per Share in cash. Pursuant to the Agreement and Plan of Merger, dated July 10, 1994, as amended, by and among the Purchaser, Parent and the Company (the "Merger Agreement"), Parent intends to effect a merger of the Purchaser with and into the Company (the "Merger") pursuant to Section 253 of the Delaware General Corporation Law as soon as practicable. Upon the consummation of the Merger, each outstanding Share (other than Shares acquired by the Purchaser in the Offer, Shares owned by a subsidiary of the Company and Shares as to which appraisal rights are perfected) will be converted into the right to receive $76.00 in cash. Prior to the expiration of the Offer, the Company completed a spin-off to its stockholders of record on November 19 of the common stock of a newly created corporation that held all of the Company's businesses and subsidiaries other than its pharmaceutical benefits management business (the "Retained Business"). Accordingly, upon consummation of the Offer and the Merger, the Company, then consisting solely of the Retained Business, will become a wholly-owned subsidiary of Parent. ITEM 10.

                       LILLY ACQUIRES MCKESSON'S PCS UNIT
 
  Eli Lilly and Company announced today that it has acquired McKesson
Corporation's subsidiary PCS Health Systems, Inc. pursuant to Lilly's tender
offer for McKesson common stock following the distribution by McKesson of its
non-PCS businesses. Plans for the acquisition were initially announced on July
11, 1994, and an agreement was reached with the Federal Trade Commission (FTC)
on November 4, 1994.
 
  "PCS and Lilly represent the ideal marriage to meet the demands of the
rapidly changing and increasingly competitive health care marketplace," said
Randall L. Tobias, Lilly chairman and chief executive officer. "PCS and Lilly
share a vision of the creation of an information-based system to help lower
overall health care costs while increasing the quality of care. By combining,
the two companies can move forward to fulfill that vision. Together, Lilly and
PCS will develop new products and services to benefit virtually every element
of the health care delivery chain."
 
  "To meet our long-term shared vision, PCS will continue to provide customers
with clinically sound and cost-effective options for the choice and utilization
of drugs," said Steve Geringer, president of PCS. "In addition, we will bring
to the marketplace disease-state-management programs that are at the core of
the PCS/Lilly vision. Given our technology, our information, and our focus on
total health management, we can improve the quality of care while, at the same
time, reducing overall medical costs. Our services will become more accessible
and affordable making consumers the biggest winners from this transaction."
 
  PCS, headquartered in Scottsdale, Arizona, is the largest and fastest growing
managed-pharmaceutical- care company in the United States. PCS provides a
variety of programs and services ranging from formulary administration and
claims processing to fully capitated programs for more than 50 million people
and 1,300 health plan sponsors.
 
  Lilly is a global research-based pharmaceutical corporation headquartered in
Indianapolis, Indiana, that is working with its customers worldwide to help
ensure that diseases are prevented, managed, and cured with maximum benefit and
minimum cost to patients and society. The company focuses its research efforts
on five disease categories: central-nervous-system and related diseases;
endocrine diseases, including diabetes and osteoporosis; infectious diseases;
cancer; and cardiovascular diseases.
 
  Lilly's tender offer for McKesson common stock expired at 5:00 p.m., New York
City time, on November 21, 1994. A total of 42,640,622 shares of McKesson
common stock (or 94.9 percent of the shares outstanding) were validly tendered
and not withdrawn pursuant to Lilly's offer, including 2,933,458 shares (6.5
percent of the shares outstanding) tendered pursuant to notices of guaranteed
delivery. Lilly has accepted these shares for payment at the purchase price of
$76.00 per share in cash. In addition, immediately prior to the consummation of
the tender offer, McKesson distributed one share of common stock of a new
McKesson corporation for each share then outstanding. The new corporation owns
all of the businesses formerly owned by McKesson other than the business of
PCS. The shares of McKesson that were not tendered (other than certain shares
held by a subsidiary of McKesson and shares as to which dissenters' rights are
asserted) will be converted into the right to receive $76.00 per share in cash
upon the consummation of a merger of a Lilly subsidiary into McKesson that is
expected to occur later this month.
