* CONFIDENTIAL *

                          Employee Retention Agreement
           Resulting from a Change in Control or Division Divestiture

       AGREEMENT made as of December 14, 1998, by and between Smith & Nephew,
Inc. (the "Company") and Les Cross (the "Executive").

       WHEREAS, the Company recognizes that the possibility of an occurrence of
a Change in Control or the Divestiture of the BASS Division of the Company can
result in significant distractions of the Company's key management personnel
because of the uncertainties inherent in such a situation; as well as
uncertainty in the business and potentially the employee's position in the
future creates uncertainty for the employee's continued employment and the
employee's position;

       WHEREAS, the Executive possesses certain skills unique to the Company's
business;

       WHEREAS, the Company has determined that it is in the best interest of
the Company to retain the services of the Executive and to ensure his continued
dedication and efforts without undue concern for his personal security; and

       WHEREAS, in order to induce the Executive to remain in the employ of the
Company, particularly in the event of a Change in Control or Division
Divestiture, the Company desires to enter into this Agreement with the Executive
to provide the Executive with certain benefits in the event his employment is
terminated as a result of, or in connection with, a Change in Control or the
Divestment of a Division, and to provide the Executive with certain other
benefits whether or not the Executive's employment is terminated.

       NOW, THEREFORE, it is agreed as follows:

       1.     Term. This Agreement shall commence as of December 31, 1998, and
              shall continue in effect until December 31, 1999, when it shall
              terminate, unless extended by written mutual agreement signed by
              the Company and the Executive; provided, however, that in the
              event that a Change in Control or Division Divestiture occurs on
              or before December 31, 1999, the term of this Agreement shall not
              expire prior to the expiration of twelve (12) months after the
              occurrence of the Change in Control or the Divestiture of the BASS
              Division.

       2.     Definitions:

       2.1    Cause. For purposes of this Agreement, "Cause" shall mean the
              misappropriation of corporate funds or other acts of dishonesty,
              activities materially harmful to the Company's business or
              reputation, willful refusal to perform or substantial disregard of
              Executive's assigned duties, or any violation of any legal
              obligation to the Company.

       2.2    Change in Control / Division Divestiture. For purposes of this
              Agreement, "Change in Control" of BASS shall be deemed to have
              occurred if as a result of a tender offer, merger consolidation,
              sale of assets, acquisition of shares or contested election, or
              any combination of the foregoing transactions, (i) any person
              shall become the owner, beneficially or of record, of more than
              30% of the aggregate voting power of the Company, other than a
              member of the Smith & Nephew Group of companies, (ii)
              substantially all of the assets of the Company shall be sold to
              another corporation; provided that the other corporation is not a
              member of the Smith & Nephew Group of companies or (iii) the
              persons who were directors of the Company immediately before the
              transaction shall cease to constitute a majority of the Board of
              Directors of the Company or any successor to the Company.

       2.3    Disability. For purposes of this Agreement, "Disability" shall
              mean a physical or mental condition which impairs the Executive's
              ability to substantially perform his duties under this Agreement
              for a period of one hundred eighty (180) consecutive days as
              determined by a company appointed health care provider.

       2.4    Good Reason. For purposes of this Agreement, "Good Reason" shall
              mean the occurrence after a Change in Control or a Division
              Divestiture of any of the events or conditions described in
              Subsections (1) through (8) hereof:

              (1)    a change in the Executive's title, position or
                     responsibilities (including reporting responsibilities)
                     which represents an adverse change from his present
                     position or responsibilities in effect immediately prior to
                     the Change in Control or the Divestiture of BASS; the
                     assignment to the Executive of any duties or
                     responsibilities which are inconsistent with his present
                     position or responsibilities in effect immediately prior to
                     the Change in Control or Divestiture of BASS; or

              (2)    a material reduction in the Executive's compensation or any
                     failure to pay the Executive any compensation or benefits
                     to which he is entitled within thirty (30) days of the date
                     due;

              (3)    the Company requiring the Executive to be based at any
                     place outside a 50-mile radius from his current location
                     except for reasonably required travel on the Company's
                     business which is not substantially greater than such
                     current travel requirements.

              (4)    the failure by the Company to continue in effect any
                     compensation or employee benefit plan in which the
                     Executive is participating, unless a substitute or
                     replacement plan has been implemented which provides
                     substantially identical compensation or benefits to the
                     Executive or unless the compensation and benefit plans are
                     the same as those offered by the company to those in
                     similar executive positions;

              (5)    the insolvency or the filing of a petition for bankruptcy
                     by the Company;

              (6)    any material breach by the Company of any provision of this
                     Agreement;




                                       2
   3



              (7)    any purported termination of the Executive's employment for
                     Cause by the Company which does not comply with the terms
                     of Section 2.1; or

              (8)    the failure of the Company to obtain an agreement from any
                     successor or assign of the Company to assume and agree to
                     perform this Agreement, as contemplated in Section 7
                     hereof.

       3.     Position and Duties. The Executive shall continue to have such
              responsibilities and authority as may be given to him from time to
              time by either the Chief Executive, President of the Company, or
              the Company's Board of Directors. The Executive shall devote
              substantially all his working time and efforts to the business of
              the Company.

       4.     Compensation and Benefits.

              a.     Salary. During the period of the Executive's employment
                     hereunder, the Company shall pay to the Executive his
                     current salary with the same frequency and on the same
                     basis that the Company normally makes salary payments to
                     other Executive personnel. This salary may be increased
                     from time to time in accordance with normal business
                     practices of the Company. If such increases take place, the
                     Company shall not thereafter decrease the Executive's
                     salary without the Executive's consent during the term of
                     this Agreement.

              b.     Benefits. The Executive shall participate in all other
                     compensation and benefit plans which are offered by the
                     Company to employees in similar executive positions, in
                     accordance with the terms of the plans.

              c.     Retention Bonus. Promptly following the Divestiture of the
                     BASS Division or a Change in Control, the Executive shall
                     receive a special retention taxable bonus equal to twelve
                     months base salary for full on-going commitment of the
                     Executive during the divestiture process and if he remains
                     in his position through the completion of the Divestiture
                     or Change in Control as determined by the Company.

                     If the Division is not sold by December 31, 1999, and the
                     Divestiture process has ceased, the Executive will be
                     eligible to receive a taxable Retention Bonus equal to 50%
                     of the Retention Bonus, as outlined in paragraph one of
                     Section 4c.

              d.     Special Sale Bonus. The Executive will be eligible to
                     receive an additional taxable bonus payment of 150% of his
                     base salary if the BASS Division is sold during the
                     Executive's employment for an amount equal to or greater
                     than $350 million ("Special Sale Bonus"). If the BASS
                     Division is sold for an amount between $225 million and
                     $350 million, then the Executive shall receive a pro rata
                     share of the Special Sale Bonus. (Accordingly, if the sale
                     price were $225 million, $250 million, $300 million, or
                     $350 million, the Special Sale Bonus would be,
                     respectively, 25%, 50%, 100%, or 150% of the Executive's
                     base salary).

       5.     Severance and Benefits.

       5.1    If within one year of a Change in Control or a Divestiture of
              BASS, the Executive is terminated by the purchasers for reasons
              other than Cause or if the executive resigns for Good Reason, then
              the Executive will be entitled to one year's base salary plus one
              year's taxable bonus (calculated as maximum normal bonus,
              excluding retention bonus), payable by the purchaser. "Severance
              Payments."

       5.2    The Severance Payments provided for in 5.1 shall be reduced by 50%
              if, upon termination of his employment, the Executive does not
              accept within ten (10) days a written offer of employment by an
              affiliate of the Company, if such offer provides for a similar
              position of employment, base salary equal to or greater than 90%
              of Executive's salary at the time of termination, relocation
              costs, temporary living expenses, and guaranteed employment for
              eighteen (18) months unless employment is terminated for Cause,
              Disability or as a result of death.

6.     Termination Date. "Termination Date" shall mean in the case of the
              Executive's death, his date of death, and in all other cases, the
              date specified in the Notice of Termination subject to the
              following:

              a.     If the Executive's employment is terminated by the Company
                     for Cause, the date specified in the notice of Termination
                     shall be the date of the action.

              b.     If the Executive's employment is terminated for Good
                     Reason, the date specified in the Notice of Termination
                     shall be at least thirty (30) days, except by mutual
                     agreement.

              c.     If the Executive Voluntarily terminates the employment
                     following the payment of the Retention Bonus and/or
                     Severance Payments without Good Reason, he agrees to
                     provide thirty (30) calendar days notice.

       7.     Successors; Binding Agreement.

              a.     This Agreement shall be binding upon and shall inure to the
                     benefit of the Company, its successors and assigns, and the
                     Company shall require any successor or assign to expressly
                     assume and agree to perform this Agreement in the same
                     manner and to the same extent that the Company would be
                     required to perform it if no such succession or assignment
                     had taken place.

              b.     Neither this Agreement nor any right or interest hereunder
                     shall be assignable or transferable by the Executive, his
                     beneficiaries or legal representatives, except for
                     compensation due the Executive as a result of his death
                     which may pass by will or by the laws of descent and
                     distribution. This Agreement shall inure to the benefit of
                     and be enforceable by the Executive's legal personal
                     representative (executors, administrators, heirs, devisees,
                     and/or legatees).

       8.     Notice. For purposes of this Agreement, notices and other
              communications provided for in the Agreement (including the Notice
              of Termination) shall be in writing and shall be deemed to have
              been duly given when personally delivered or sent by certified
              mail, return receipt requested, addressed to the respective
              addresses last given by each party to the other. All notices and
              communications shall be deemed to have been received on the date
              of personal delivery thereof or on the third business day after
              the mailing thereof, except that notice of change of address shall
              be effective only upon receipt by a designated representative of

       9.     Non-exclusivity of Rights. Nothing in this Agreement shall prevent
              or limit the Executive's continuing or future participation in any
              benefit, bonus, incentive or other plan or program provided by the
              Company and for which the Executive may qualify, nor shall
              anything herein limit or reduce such rights as the Executive may
              have under any other agreements with the Company. Provided,
              however, that to the extent that the Executive receives benefits
              under this Agreement because of a Division Divestiture, he or she
              is not entitled to severance pay under any other severance plan,
              policy or arrangement of the Company. Amounts which are vested
              benefits or which the Executive is otherwise entitled to receive
              under any plan or program of the Company shall be payable in
              accordance with such plan or program, except as explicitly
              modified by this Agreement.

       10.    Miscellaneous. No provision of this Agreement may be modified,
              waived or discharged unless such waiver, modification or discharge
              is agreed to in writing and signed by the Executive and the
              Company. No waiver by either party hereto at any time of any
              breach by the other party hereto of, or compliance with, any
              condition or provision of this Agreement to be performed by such
              other party shall be deemed a waiver of similar or dissimilar
              provisions or conditions at the same time or at any prior or
              subsequent time. No agreement or representations, oral or
              otherwise, express or implied, with respect to the subject matter
              hereof have been made by either party which are not expressly set
              forth in this Agreement.

       11.    Governing Law. This Agreement shall be governed by and construed
              and enforced in accordance with the laws of the State of
              California without giving effect to the conflicts of law
              principles thereof.

       12.    Severability. The provisions of this Agreement shall be deemed
              severable and the invalidity or unenforceability of any provision
              shall not effect the validity or enforceability of the other
              provisions hereof.

       13.    Reduction of Payments by the Company. If any payment or benefit
              received by or in respect of the Executive under this Agreement or
              any other plan, arrangement or agreement with the Company or any
              other member of the Smith & Nephew Group of companies, (determined
              without regard to any additional payments required under this
              Section 13) (a "Payment") would be subject to the tax (the "Excise
              Tax") imposed by Section 4999 of the Internal Revenue Code of
              1986, as amended (or any similar tax that may hereafter be
              imposed), the Company shall pay to the Executive with respect to
              such Payment an additional amount (the "Gross-up Payment") such
              that the net amount retained by the Executive from the Payment and
              the Gross-up Payment, after reduction for any Excise Tax upon the
              Payment and any federal, state and local income tax and Excise Tax
              upon the Gross-up Payment, shall be equal to the Payment.
