3.   In March 2000, a wholly-owned subsidiary of the Company issued $1.5 billion
     par value of variable rate preferred units. The units are redeemable at par
     value plus accrued dividends at the option of the issuer at any time. They
     are also redeemable at the option of the holders in March 2010, and at the
     end of each five-year interval thereafter. The preferred units are included
     in Minority interests in the consolidated financial statements.

4.   The Company, along with numerous other defendants, is a party in several
     antitrust actions brought by retail pharmacies and consumers, alleging
     conspiracies in restraint of trade and challenging pricing and/or
     purchasing practices, one of which has been certified as a federal class
     action and a number of which have been certified as state class actions. In
     1996, the Company and several other defendants finalized an agreement to
     settle the federal class action alleging conspiracy, which represents the
     single largest group of retail pharmacy claims, pursuant to which the
     Company paid $51.8 million. Since that time, the Company has entered into
     other settlements on satisfactory terms. The Company has not engaged in any
     conspiracy, and no admission of wrongdoing was made nor was included in the
     final agreements. While it is not feasible to predict or determine the
     final outcome of these proceedings, management does not believe that they
     should result in a materially adverse effect on the Company's financial
     position, results of operations or liquidity.

     Segment profits are comprised of segment revenues less certain elements of
     materials and production costs and operating expenses, including components
     of equity income (loss) from joint ventures and depreciation and
     amortization expenses. The Company does not internally allocate the vast
     majority of indirect production costs, research and development expenses
     and general and administrative expenses, all predominantly related to the
     Merck pharmaceutical business, as well as the cost of financing these
     activities. Separate divisions maintain responsibility for monitoring and
     managing these costs, including depreciation related to fixed assets
     utilized by these divisions and, therefore, they are not included in the
     marketing segment profits. The vast majority of goodwill and other
     intangibles amortization, predominantly related to the Merck-Medco
     business, as well as the cost of financing capital employed, also are not
     allocated internally and, therefore, are not included in the marketing
     segment profits.

     A reconciliation of total segment profits to consolidated income before
     taxes is as follows:

     Other profits primarily represent operating income related to divested
     products or businesses. Adjustments represent the elimination of the effect
     of double counting certain items of income and expense. Equity income from
     affiliates includes taxes paid at the joint venture level and a portion of
     equity income that is not reported in segment profits. Other expenses, net,
     include expenses from corporate and manufacturing cost centers and other
     miscellaneous income (expense), net.

             MANAGEMENT'S ANALYSIS OF INTERIM FINANCIAL INFORMATION

Earnings per share for the first quarter of 2000 were $0.63, an increase of 17%
over the first quarter of 1999. First quarter net income increased 15% to
$1,499.6 million. Sales for the quarter were $8.9 billion, up 17% from the same
period last year.

Sales growth for the quarter was led by 'Vioxx', the fastest growing
prescription arthritis medicine in the United States, other newer and
established products and growth from the Merck-Medco Managed Care business.
Overall, worldwide operations reported strong sales volume gains.

Sales of Merck human health products increased 17% for the first quarter. Sales
of Merck human health products outside of the United States accounted for 37% of
Merck human health sales. Foreign exchange had essentially no effect on the
human health sales growth for the first quarter.

Income growth for the quarter was driven by strong sales volume gains as well as
manufacturing productivity improvements. The savings from productivity
improvements helped fund selling and promotion programs to support new products
as well as research and development.

Five key products - 'Vioxx', 'Zocor', 'Fosamax', 'Singulair' and
'Cozaar'/'Hyzaar'* - led Merck's growth, and now account for more than 50% of
Merck's worldwide human health sales. Supply shipments to AstraZeneca LP also
contributed to sales volume growth.

'Vioxx' remains the fastest growing prescription arthritis medicine in the
United States. More than 9 million prescriptions have been written for 'Vioxx'
since its U.S. introduction 10 months ago. In addition, it is the only medicine
specifically inhibiting COX-2 that is indicated both for treatment of
osteoarthritis and for relief of acute pain, such as pain following knee, hip
replacement and dental surgery. 'Vioxx' is enjoying strong success in the
European countries where it has been launched, including the United Kingdom,
Germany and Spain. In all, 'Vioxx' has been launched in more than 50 countries.

Merck is conducting extensive clinical studies with 'Vioxx' to evaluate its
efficacy in the treatment of rheumatoid arthritis and in the prevention and
treatment of Alzheimer's disease. Merck has also begun studies to investigate
whether 'Vioxx' can reduce the number of colon polyps in patients who suffer
from them - a broad population at risk of developing colon cancer.

Sales of 'Zocor' continue to show strong growth. Extensive studies showed that
this cholesterol-modifying medicine saves lives by preventing heart attacks and
other cardiovascular events. The first study comparing 'Zocor' 80 mg, the
highest recommended dose, with atorvastatin 80 mg showed that 'Zocor' increased
levels of both "good" (HDL) cholesterol and a key component of good cholesterol
called apolipoprotein (apo A-I) to a greater degree. Low HDL has been identified
as a risk factor for heart disease. The independent effect of raising HDL on
cardiovascular disease has not been determined.

Merck's high blood pressure medication 'Cozaar' and its companion agent 'Hyzaar'
rank among the Company's fastest-growing products. 'Cozaar' is currently
registered in more than 90 countries, where it has been used to treat more than
7 million patients. 'Cozaar' is the world's most widely prescribed medication in
the angiotensin II antagonist class and it continues its strong growth, as
physicians increasingly recognize the excellent tolerability and efficacy of
these two products.

Results from a new study with 'Cozaar' and 'Hyzaar' have countered a
traditionally held belief that African Americans might not be responsive to
recently developed antihypertensives. Physicians traditionally have prescribed
older classes of drugs, such as diuretics and calcium channel blockers, to treat
hypertension in this population. Average blood pressure levels are higher in
African Americans compared to Caucasians, and African Americans tend to develop
hypertension earlier in life. As a result, they are more vulnerable to heart
attack, stroke and kidney failure. Study results showed that African Americans
with hypertension who were treated with 'Cozaar' and 'Hyzaar' demonstrated
statistically significant reductions in blood pressure compared to placebo.

'Fosamax' is available in more than 100 countries and continues as the leading
product worldwide for the treatment of postmenopausal osteoporosis. 'Fosamax'
remains the only non-hormonal medicine proven to reduce the incidence of hip
fractures, the most serious fractures related to osteoporosis. Merck has
submitted an application to the U.S. Food and Drug Administration (FDA) for
approval to market 'Fosamax' to treat osteoporosis in men. The Company also has
filed with the FDA and with regulatory agencies worldwide for a convenient
once-weekly formulation, which has already received approval in Mexico.

*'Cozaar' and 'Hyzaar' are registered trademarks of E.I. du Pont de Nemours and
Company, Wilmington, DE, USA.

MANAGEMENT'S ANALYSIS OF INTERIM FINANCIAL INFORMATION (continued)

'Singulair' is now the third-largest selling branded product for the chronic
treatment of asthma. Merck recently filed for regulatory approval to market
'Singulair' in Japan, the world's second-largest national pharmaceutical market.
'Singulair' became the first asthma controller therapy in more than 15 years
indicated for children as young as two, following FDA approval to market the 4
mg chewable tablet for children ages two to five. Similar applications are
pending in Europe and Latin America. This new indication is significant because
asthma remains the most prevalent chronic disease of childhood, affecting an
estimated 1 in 10 children, and its prevalence and incidence is increasing.

On February 22, 2000, the Board of Directors declared a quarterly dividend of 29
cents per share on the Company's common stock which was paid April 3 to
stockholders of record at the close of business on March 3. The Company's total
dividend paid to date in 2000 is 58 cents per share, a seven percent increase
over the amount paid during the same period in 1999.

In February 2000, the Company completed the $5.0 billion share repurchase
program authorized by the Board of Directors in July 1998 and the Board approved
purchases of up to an additional $10.0 billion of Merck shares. The Company
purchased a total of $2.1 billion of treasury shares in the first quarter of
2000 under the programs.

In March 2000, a wholly-owned subsidiary of the Company issued $1.5 billion par
value of variable rate preferred units. The units are redeemable at par value
plus accrued dividends at the option of the issuer at any time. They are also
redeemable at the option of the holders in March 2010, and at the end of each
five - year interval thereafter. The proceeds will be used for general corporate
purposes. The preferred units are included in Minority interests in the
consolidated financial statements.

In April 2000, Merck-Medco Managed Care, L.L.C. (Merck-Medco) introduced a new
service, YOURxPLAN, a prescription savings plan for people who have to pay for
medicines out of their own pockets. With discounts on virtually all prescription
drugs, plus additional cash back savings on some major medicines, YOURxPLAN
allows people of all ages to save money on their drug bills. Merck's partner in
this venture is Reader's Digest, one of the nation's premier direct marketers
and most trusted resources for health information and products.

On May 4, 2000, the Company entered into a definitive agreement to acquire all
of the outstanding common shares of ProVantage Health Services, Inc.
(ProVantage), a pharmaceutical benefit services company, for $12.25 per share or
an estimated aggregate purchase price of $222.0 million. ProVantage would become
part of Merck-Medco. The proposed acquisition, which would be accounted for by
the purchase method, would not have a material impact on the Company's results
of operations or financial position.

In June 1998, the Financial Accounting Standards Board (FASB) issued Statement
No. 133, Accounting for Derivative Instruments and Hedging Activities (FAS 133).
The Statement established accounting and reporting standards requiring that
every derivative instrument be recorded in the balance sheet as either an asset
or liability measured at fair value and that changes in fair value be recognized
currently in earnings, unless specific hedge accounting criteria are met. In
June 1999, the FASB issued Statement No. 137, Accounting for Derivative
Instruments and Hedging Activities -- Deferral of the Effective Date of FASB
Statement No. 133, which delayed the Company's required adoption of FAS 133 to
January 1, 2001. The Company will adopt the Statement at that time. The FASB is
currently finalizing certain amendments to FAS 133. The effect of the final
statement on the Company's financial position or results of operations has not
yet been determined.

CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS

This report and other written reports and oral statements made from time to time
by the Company may contain so-called "forward-looking statements," all of which
are subject to risks and uncertainties. One can identify these forward-looking
statements by their use of words such as "expects," "plans," "will,"
"estimates," "forecasts," "projects" and other words of similar meaning. One can
also identify them by the fact that they do not relate strictly to historical or
current facts. These statements are likely to address the Company's growth
strategy, financial results, product approvals and development programs. One
must carefully consider any such statement and should understand that many
factors could cause actual results to differ from the Company's forward-looking
statements. These factors include inaccurate assumptions and a broad variety of
other risks and uncertainties, including some that are known and some that are
not. No forward-looking statement can be guaranteed and actual future results
may vary materially.

The Company does not assume the obligation to update any forward-looking
statement. One should carefully evaluate such statements in light of factors
described in the Company's filings with the Securities and Exchange Commission,
especially on Forms 10-K, 10-Q and 8-K (if any). In Item 1 of the Company's
Annual Report on Form 10-K for the year ended December 31, 1999, as filed on
March 22, 2000, the Company discusses in more detail various important factors
that could cause actual results to differ from expected or historic results. The
Company notes these factors for investors as permitted by the Private Securities
Litigation Reform Act of 1995. One should understand that it is not possible to
predict or identify all such factors. Consequently, the reader should not
consider any such list to be a complete statement of all potential risks or
uncertainties.

For purposes of computing these ratios, "earnings" consist of income before
taxes, one-third of rents (deemed by the Company to be representative of the
interest factor inherent in rents), interest expense, net of amounts
capitalized, and dividends on preferred stock of subsidiary companies. "Fixed
charges" consist of one-third of rents, interest expense as reported in the
Company's consolidated financial statements and dividends on preferred stock of
subsidiary companies.
