BIOMET, INC.

DEFERRED COMPENSATION PLAN

(PRE-409A GRANDFATHERED PLAN)

PREAMBLE

1. The Company established the Biomet, Inc. Deferred Compensation Plan ("Prior Plan"), effective as of December 1, 2003. The purpose of the Prior Plan as well as the current Plan is to provide a select group of key management and highly compensated employees and the members of the Biomet, Inc. Board of Directors an opportunity, in accordance with the terms and conditions set forth herein, to defer the receipt of compensation. By offering this Plan, the Company intends to build management loyalty and its business; provide a tax deferral alternative; permit deferral of amounts beyond the limits of its qualified plans; and further enhance existing benefit plans.

2. Notwithstanding any provision in the Plan to the contrary, effective January 1, 2005, the Plan is frozen and (i) all Participant deferral elections under this Plan shall be deemed to be terminated under this Plan as of December 31, 2004 and no additional deferral contributions under Section 4.1 of the Plan shall be made after such date, and (ii) no Company discretionary or matching contributions shall be made under Section 4.2 of the Plan after December 31, 2004. Any contributions made or received after December 31, 2004 shall be deemed to be contributed under the Biomet, Inc. Deferred Compensation Plan (Post-409A Plan), effective as of January 1, 2005 and as amended from time to time thereafter. All amounts contributed to this Plan were deferred and Vested as of December 31, 2004; therefore, all Plan Accounts (and any earnings thereon) maintained under this Plan are intended to be grandfathered amounts exempt from the application of Code Section 409A and will be administered accordingly.

3. The Plan is an unfunded benefit plan within the meaning of ERISA and the Internal Revenue Code. Benefits payable under the Plan with respect to a participant or beneficiary shall be paid from the general assets of the Company. To assist the Company in meeting its obligations under the Plan, the Company has established a trust. The right of a participant or beneficiary to receive payment under the Plan is merely a contractual right to payment from the Company and the Plan does not give participants or beneficiaries any interest in, or right to, any of the assets of any affiliated employer other than as a general creditor of his employer.

4. Participation in the Plan is voluntary. A Participant may elect to defer a portion of his or her Compensation under the Plan and, at all times, shall be 100% Vested in amounts credited to his or her Deferral Account. Under this Plan, the Company has no obligations to make employer contributions to the Plan, however, the Company shall retain the right to make discretionary allocations to the Account of Participants at the times and in the amounts designated by the Company in its sole discretion.

DEFINITIONS AND CONSTRUCTION

Section 1.1. Definitions . Whenever the following words and phrases are used in this Plan, with the first letter capitalized, they shall have the meanings specified below.

(a) "Account" or "Accounts" shall mean all of such accounts as are specifically authorized for inclusion in this Plan.

(b) "Base Salary" shall mean that portion of a Participant’s Compensation that is his or her annual base salary, excluding Bonuses, Commissions, incentive and all other remuneration for services rendered to the Company.

(c) "Beneficiary" or "Beneficiaries" shall mean the person or persons, including a trustee, personal representative or other fiduciary, last designated in writing by a Participant in accordance with procedures established by the Committee to receive the benefits specified hereunder in the event of the Participant’s death. No beneficiary designation shall become effective until it is filed with the Committee. Any designation shall be revocable at any time through a written instrument filed by the Participant with the Committee with or without the consent of the previous Beneficiary. No designation of a Beneficiary other than the Participant’s spouse shall be valid unless consented to in writing by such spouse. If there is no such designation or if there is no surviving designated Beneficiary, then the Participant’s surviving spouse shall be the Beneficiary. If there is no surviving spouse to receive any benefits payable in accordance with the preceding sentence, the duly appointed and currently acting personal representative of the Participant’s estate (which shall include either the Participant’s probate estate or living trust) shall be the Beneficiary. In any case where there is no such personal representative of the Participant’s estate duly appointed and acting in that capacity within 90 days after the Participant’s death (or such extended period as the Committee determines is reasonably necessary to allow such personal representative to be appointed, but not to exceed 180 days after the Participant’s death), then Beneficiary shall mean the person or persons who can verify by affidavit or court order to the satisfaction of the Committee that they are legally entitled to receive the benefits specified hereunder. In the event any amount is payable under the Plan to a minor, payment shall not be made to the minor, but instead be paid (a) to that person’s living parent(s) to act as custodian, (b) if that person’s parents are then divorced, and one parent is the sole custodial parent, to such custodial parent, or (c) if no parent of that person is then living, to a custodian selected by the Committee to hold the funds for the minor under the Uniform Transfers or Gifts to Minors Act in effect in the jurisdiction in which the minor resides. If no parent is living and the Committee decides not to select another custodian to hold the funds for the minor, then payment shall be made to the duly appointed and currently acting guardian of the estate for the minor or, if no guardian of the estate for the minor is duly appointed and currently acting within 60 days after the date the amount becomes payable, payment shall be deposited with the court having jurisdiction over the estate of the minor. Payment by the Company pursuant to any unrevoked Beneficiary designation, or to the Participant’s estate if no such designation exists, of all benefits owed hereunder shall terminate any and all liability of the Company.
