                       REPORT OF INDEPENDENT ACCOUNTANTS

                                    --------


To the Plan Administrator of
the Tiffany & Co. Employee
  Stock Ownership Plan:


We have audited the accompanying statements of assets, liabilities and
participants' equity of the Tiffany & Co. Employee Stock Ownership Plan as of
January 31, 1994 and 1993, and the related statements of changes in
participants' equity for the years ended January 31, 1994 and 1993.  These
financial statements are the responsibility of the Plan's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the assets, liabilities and participants' equity as of
January 31, 1994 and 1993, and the statements of changes in participants'
equity for the years ended January 31, 1994 and 1993 in conformity with
generally accepted accounting principles.

As discussed in Note 6 to the financial statements, the Plan changed its method
of reporting benefits payable to plan participants during fiscal 1992.

                         NOTES TO FINANCIAL STATEMENTS

                                 --------------



1.       Organization

         The Tiffany & Co. Employee Stock Ownership Plan (the "Plan") was
         established as a defined contribution plan on February 1, 1988 for
         eligible employees of Tiffany & Co. (the "Company").  The Plan is
         non-contributory on the part of the Company's employees and is
         administered by the plan administrator appointed by the Board of
         Directors of the Company.  All administrative expenses incurred in
         connection with the Plan are paid by the Company.  The Plan is funded
         by Company contributions to be invested exclusively in shares of
         Tiffany & Co. common stock.  The assets of the Plan are maintained and
         transactions therein are executed by the trustee, Chemical Bank.

2.       Summary of Significant Accounting Policies

         Basis of Presentation

         The accompanying financial statements have been presented on an
         accrual basis and present the Statements of Assets, Liabilities and
         Participants' Equity at fair value.

         Net Appreciation/(Depreciation) in Fair Value of Investments

         The Plan presents in the Statement of Changes in Participants' Equity
         the net appreciation/(depreciation) in the fair value of its
         investments, which consists of the realized gains or losses and the
         unrealized appreciation/(depreciation) on those investments.

3.       Contributions and Benefits

         A.      Contributions

                 The Company's contributions to the Plan, if any, are based
                 upon the achievement of targeted earnings objectives as
                 determined by the Board of Directors.  Such determination
                 shall be made in accordance with and subject to the terms and
                 limitations of the Tiffany & Co. Employee Stock Ownership Plan
                 adopted on February 1, 1988.  There were no contributions made
                 for the years ended January 31, 1994 and 1993, respectively.





                                      -6-

<PAGE>   7
3.       Contributions and Benefits, (Continued)

         B.      Participation

                 Each employee of the Company who was hired on or before
                 February 1, 1988, and who was an employee on such date became
                 a participant in the Plan.  Other employees shall become
                 participants in the Plan on the first day of February
                 following the initial date of employment. Persons who are
                 designated executive officers of the Company are not eligible
                 to participate in the Plan's ESOP feature.

         C.      Benefit Allocation

                 A separate account is maintained on behalf of each
                 participant.  The Company's contributions for each Plan year
                 are allocated to the accounts of eligible participants on a
                 per capita basis.  The Board of Directors of the Company
                 authorized a contribution allocable on a per capita basis to
                 participants who were employees on February 1, 1988 and
                 employed prior to such date.

                 An individual is eligible to share in the Company's
                 contribution for a Plan year, if the individual is a
                 participant and an employee for the entire Plan year and has
                 worked 1,000 hours or more during that Plan year.

         D.      Vesting

                 Each participant is fully vested in the shares or other assets
                 allocated to the participant's account after two or more years
                 of service.  In the event a participant leaves the Company
                 prior to being fully vested, the participant will forfeit the
                 shares and the shares will remain in the Plan to be
                 reallocated amongst the remaining participants.

         E.      Termination

                 Participants who retire or terminate employment receive the
                 full vested balance of the participant's account in a lump sum
                 distribution of shares in Tiffany & Co. common stock with cash
                 being distributed in lieu of fractional shares.  In the event
                 of retirement, a participant may elect to defer distribution
                 until the next Plan year thereby entitling the participant to
                 their proportionate share of the Company's contribution for
                 the Plan year in which the participant retired.  In the event
                 of a participant's death, the distribution of the
                 participant's account will be made to the participant's
                 designated beneficiary or the participant's estate, if no
                 beneficiary has been designated.

4.       Tax Status

         A favorable determination letter has been received from the Internal
         Revenue Service ruling that the Plan constitutes a qualified Plan
         under







                                      -7-

<PAGE>   8

4.       Tax Status (Continued)

         Section 401(a) of the Internal Revenue Code and, accordingly, the Plan
         is exempt from Federal income taxes.  The Plan has been amended
         subsequent to January 31, 1994 (see Note 8), and management of the
         Company believes the Amended Plan will constitute a qualified plan
         under Section 401(k) of the Internal Revenue Code and will be exempt
         from Federal income taxes.  The Company plans to file for a revised
         determination letter in fiscal 1994.

5.       Plan Termination Provisions

         The Board of Directors of the Company may terminate the Plan at any
         time at its discretion.  However, the Board of Directors of the
         Company currently intends to continue the Plan in effect.

6.       Change in Accounting Method

         Effective January 31, 1992, the Plan changed its method of accounting
         for benefits payable to persons who have elected to withdraw from the
         Plan but have not yet been paid.  In conformity with generally
         accepted accounting principles, these amounts are no longer included
         in the financial statements.  No assets were allocated to such
         individuals at January 31, 1994, while $2,720 was allocated at January
         31, 1993.

         The withdrawing participants allocated Plan assets will be reflected
         as a liability of the Plan to such individuals on the Plan's Form 
         5500 filing with the Department of Labor.

7.       Subsequent Event

         On May 19, 1994, the Tiffany & Co. Employee Stock Ownership Plan was
         amended to include a cash or deferred savings arrangement under
         Section 401(k) of the Internal Revenue Code (the "Code") of 1986, as
         amended.  The Plan was amended and renamed the "Tiffany & Co. Employee
         Profit Sharing and Retirement Savings Plan" (the "Amended Plan").  The
         Amended Plan shall become effective August 1, 1994.

         A participant's eligibility for the 401(k) benefits under the Amended
         Plan shall be determined by the period of service.  Service shall be
         based upon hours of employment, which must exceed 1,000 hours during
         the plan year, and years of service.  A year of service shall be
         determined by reference to the date on which the participant's
         employment commenced or re- commenced and shall consist of
         twelve-month periods commencing with such date.  Participants in the
         old Plan are fully eligible to participate in the Amended Plan.

         Under the Amended Plan, participants will have the option of electing
         to have an amount between one (1) and fifteen (15) percent of their
         annual compensation contributed, not to exceed $9,240 in 1994 subject
         to an annual inflation adjustment, as a tax deferred contribution.  In
         addition, under Section 401(k) of the Code, highly compensated
         employees are limited in the amount of tax deferred contributions they
         may make.  All amounts







                                      -8-

<PAGE>   9
7.       Subsequent Event (Continued)

         contributed by employees will be 100% vested and nonforfeitable at all
         times.

         A participant may request a withdrawal, in cash, of all or a portion
         of the value of his tax deferred contributions (excluding all earnings
