REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Board of Directors
Perrigo Company
Allegan, Michigan

We have audited the accompanying statements of net assets available for benefits
of Perrigo Company Profit-Sharing and Investment Plan as of December 31, 2005
and 2004, and the related statements of changes in net assets available for
benefits for the years then ended. These financial statements are the
responsibility of the Plan Administrator. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform an audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Company's internal control
over financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, 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 net assets available for benefits of Perrigo Company
Profit-Sharing and Investment Plan as of December 31, 2005 and 2004, and the
changes in net assets available for benefits for the years then ended, in
conformity with accounting principles generally accepted in the United States of
America.

Our audits were made for the purpose of forming an opinion on the financial
statements taken as a whole. The supplemental schedule of assets (held at end of
year) as of December 31, 2005 is presented for the purpose of additional
analysis and is not a required part of the basic financial statements, but is
supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan Administrator. The supplemental schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements, and, in our
opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

1.       PLAN DESCRIPTION

         The following description of the Perrigo Company Profit-Sharing and
         Investment Plan (formerly the L. Perrigo Investment Plan and Trust)
         (Plan) provides only general information. Participants should refer to
         the plan agreement or plan summary for a more complete description of
         the Plan's provisions.

         GENERAL

         The Plan is a defined contribution plan in which substantially all
         employees of Perrigo Company, Perrigo Company of South Carolina,
         Perrigo Sales Company, Perrigo Research and Development, Perrigo
         Pharmaceuticals and Perrigo International, Inc. (Company) are eligible
         to participate. As of September 1, 2005, the minimum term of service
         for employees to participate in the Plan is one month of service which
         means a consecutive 30-day period of employment beginning with the
         Employee's date of hire. Prior to September 1, 2005 the eligibility
         requirement was a consecutive four-month period of employment. Plan
         entry dates are at the beginning of each payroll period after the
         minimum term requirements are satisfied. For employees hired after
         December 31, 2002, the Plan has automatic enrollment. Under this
         enrollment, 2% of participant's compensation will automatically be
         deferred into the Plan. The 2% automatic deferral amount is invested in
         the Putnam Money Market Fund. The participant has the option to
         withdraw from the Plan within 45 days after participant eligibility is
         met, or choose to increase the deferral percentage. For employees hired
         after September 1, 2005, the Plan increases the automatic enrollment
         percentage by 1% in each of the following two years to bring the total
         deferral amount to at least 4%. The Plan is subject to the provisions
         of the Employee Retirement Income Security Act of 1974 (ERISA). The
         Plan is administered by an administrative committee (Committee).

         CONTRIBUTIONS

         A participant may contribute to the Plan annually an amount not less
         than 1% and not more than 50% of his or her compensation, up to the
         dollar limit set by the federal government (for 2005, limit is
         $14,000). Participants who are at least 50 years of age by the end of a
         Plan year, may elect to make an additional "catch up" contribution
         salary deferral for that Plan year (for 2005, "catch up" limit is
         $4,000). The Company has agreed to match employee contributions per

         contributions in the Plan is one year. Amounts credited to a
         participant's investment account relating to participant contributions
         and employer matching contributions are 100% vested at all times. The
         Company has the right under the Plan to discontinue such contributions
         at any time.

         The Company has agreed to voluntarily contribute such amounts as
         determined by the board of directors of the Company. The Employer's
         voluntary contribution is allocated based on the ratio of the
         participant's eligible compensation to aggregate participants' eligible
         compensation for the year. Vesting of the Employer's voluntary
         contribution begins at 33% when two years of service are met and then
         increases at a rate of 33% for each additional year of service until
         100% is reached after four years.

         Discretionary contributions in the amounts of $4,063,551 and $5,404,979
         were made by the Company in 2005 and 2004, respectively.

         PARTICIPANT ACCOUNTS

         Participants direct the investment of their contributions, the employer
         matching contribution and the Employer's voluntary contribution into
         various investment options offered by the Plan. Currently, the Plan
         offers mutual funds, a common/collective trust and the Company's common
         stock as investment options for plan participants.

         PARTICIPANT LOANS

         Participants may, with the consent of the Committee, borrow an amount
         not to exceed the lesser of 50% of their account balance or $50,000.
         The amount must be at least $1,000. The loans are secured by an
         equivalent amount in the remaining portion of the participant's salary
         deferral contribution and rollover accounts. All loans must be repaid
         within five years, except for loans used to acquire or rehabilitate a
         principal residence, which must be repaid within ten years. Interest
         rates ranged from 6.0% to 11.5% on outstanding loans at December 31,
         2005. The loans are repaid ratably through payroll deductions. The
         interest earned on participant loans is allocated to the respective
         funds, in accordance with participant elections.

         WITHDRAWALS

         A participant may elect to withdraw up to an amount equal to the
         balance in the participant's elective contribution account on the
         allocation date coinciding with or


                                                                               7

         immediately preceding the date of withdrawal, provided the Committee
         determines that: (1) the purpose of the withdrawal is to meet an
         immediate and heavy financial need of the participant, (2) the amount
         of the withdrawal does not exceed such financial need, (3) the amount
         of the withdrawal is not reasonably available from other resources of
         the participant, and (4) all available plan loans have been taken. This
         hardship withdrawal is subject to 10% federal income tax penalty and
         the participant cannot make elective deferrals for 6 months following
         the hardship withdrawal.

         A participant may also elect to make a similar withdrawal, provided
         that participant has reached fifty-nine and one half years of age, even
         if the participant is still employed.

         PAYMENT OF BENEFITS

         Upon termination of service, a participant may elect to receive either
         a lump-sum amount equal to the value of the participant's vested
         account or annual installments. Participants may also elect to transfer
         their account balance into another qualified retirement plan.

         FORFEITURES

         Forfeited unvested accounts in the amount of $30,978 and $67,768 in
         2005 and 2004, respectively, were reallocated to remaining plan
         participants. Forfeitures are applied to participant accounts as an
         additional employer discretionary contribution. No additional forfeited
         amounts remained in the Plan at December 31, 2005.

2.       SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF ACCOUNTING

         The accompanying financial statements have been prepared under the
         accrual method of accounting.

         USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
         accepted accounting principles in the United States of America requires
         management to make estimates and assumptions that affect the reported
         amounts of net assets and changes therein. Actual results could differ
         from those estimates. The Plan utilized various investment instruments,
         which are exposed to various risks, such as interest rate, credit, and
         overall


                                                                               8

================================================================================


         market volatility. Due to the level of risk associated with certain
         investment securities, it is reasonably possible that changes in the
         values of investment securities will occur in the near term and that
         such changes could materially affect participant's account balances and
         the amounts reported in the financial statements.

         INVESTMENT VALUATION AND INCOME RECOGNITION

         Investments in mutual funds and Perrigo Company common stock are stated
         at fair value based on quoted market prices. Common/collective trust is
         stated at its fair value as determined by the trustee/custodian based
         upon quoted market prices of the underlying securities. Participant
         loans are stated at cost, which approximates fair value. Investment
         purchases and sales are recorded on a trade-date basis. Interest is
         recorded on an accrual basis.

         PAYMENT OF BENEFITS

         Benefits are recorded when paid.

3.       ASSETS IN TRUST FUND

         Under the terms of the trust agreement with Putnam Fiduciary Trust
         Company (Putnam), the custodian manages the trust fund on behalf of the
         Plan. Putnam has discretionary investment authority over the
         investments held in each investment option made available to
         participants, except for the investments in Perrigo Company common
         stock.

4.       RELATED PARTY TRANSACTIONS

         Certain Plan investments throughout the year represented shares of
         various types of investments that were managed by Mercer. These
         transactions qualify as party-in-interest. Administrative fees paid by
         the Plan to Mercer amounted to $13,603 and $12,063 in 2005 and 2004,
         respectively.

5.       PLAN TERMINATION

         Although it has not expressed any intent to do so, the Employer has the
         right to discontinue contributions at any time and to terminate the
         Plan, subject to the provisions of ERISA. In the event of termination,
         all participants will become fully vested in their accounts.


                                                                              11

6.       INCOME TAX STATUS

         The Plan obtained its latest determination letter on October 3, 2002,
         in which the Internal Revenue Service stated that the Plan was in
         compliance with the applicable requirements of the Internal Revenue
         Code (Code). The Plan has been amended since receiving the
         determination letter. However, the Plan Administrator and the Plan's
         tax counsel believe that the Plan is currently designed and being
         operated in compliance with the applicable requirements of the Code.
         Therefore, no provision for income taxes has been included in the
         Plan's financial statements.
