              Item 3. Source and Amount of Funds or Other Consideration.

     Pursuant to a Stock Purchase Agreement dated January 14, 1998, (the
     "Purchase Agreement") between S&N and ATS, S&N acquired 1,533,115 shares of
     the ATS Common Stock for $13.0453333333 per share or a total of
     $19,999,996.21. The funds for such acquisition were obtained from working
     capital at the parent company level which were either loaned or contributed
     to S&N.

     Pursuant to a Promissory Note dated March 31, 1997 as amended June 18, 1999
     (the "Note"), S&N loaned ATS $10,000,000. This loan was repayable by ATS in
     either cash or, under certain circumstances, ATS Common Stock. The funds
     for such loan were obtained from working capital at the parent company
     level which were either loaned or contributed to S&N. On June 18, 1999 ATS
     notified S&N of its election, pursuant to Section 2.3 of the Note, to repay
     the outstanding amounts under the Note in shares of ATS Common Stock. On
     June 30, 1999 ATS issued S&N 2,800,595 additional shares of ATS Common
     Stock.

     Pursuant to an Agreement, dated May 6, 1994, between S&N and ATS, S&N
     loaned ATS $10,000,000. The funds for such loan were obtained from working
     capital at the parent company level which were either loaned or contributed
     to S&N. On September 29, 2000, ATS paid S&N $4,300,000 in cash on the loan,
     with the remaining balance of $5,700,000 being paid to S&N by the issuance
     of 770,453 shares of ATS Common Stock.

              Item 4. Purpose of Transaction.

The purpose of acquiring the shares is for investment. Depending upon its
evaluation of ATS' business prospects and financial condition, the market for
ATS Common Stock and other factors that it may deem material to its investment
decision, S&N may acquire additional shares of ATS Common Stock in the open
market, in private transactions or by any other permissible means or may dispose
of all or a portion of the shares of ATS Common Stock which are currently owned
or which are hereafter acquired.

On October 10, 2002, in connection with their bankruptcy filing, ATS and certain
of its subsidiaries filed a Section 363 motion to allow S&N to purchase certain
of their assets and certain equity interests held by such entities. This
transaction and a related loan agreement are more fully described in Item 6
hereof. S&N would fund the proposed transaction and financing from capital
contributions or loans from its parent company. The parent company expects to
provide any funds necessary from working capital.

                                        7



            Item 5.   Interest in Securities of the Issuer.

     S&N holds 5,104,163 shares of ATS Common Stock representing approximately
     6.98% of the 73,154,753 issued and outstanding shares as of August 9, 2002.

     The number of shares of ATS Common Stock as to which S&N has:

                (i)   sole power to vote or direct the vote is 5,104,163 shares;
                (ii)  shared power to vote or to direct the vote is 0 shares;
                (iii) sole power to dispose or to direct the disposition is
                      5,104,163; and (iv) shared power to dispose or direct the
                      disposition is 0.

     No other transactions in ATS Common Stock were effected by Parent, Holdings
     or S&N within the past sixty days.

            Item 6.   Contracts, Arrangements, Understandings or Relationships
                      with Respect to Securities of the Issuer.

     S&N and ATS are involved in a variety of ongoing arrangements and
     understandings. In April 1996, S&N and ATS entered into an agreement to
     form a fifty-fifty joint venture for the worldwide commercialization of
     Dermagraft, ATS' tissue-engineered replacement for the treatment of
     diabetic foot ulcers (the "Dermagraft Joint Venture"). In January 1998, S&N
     and ATS expanded the Dermagraft Joint Venture to include, with certain
     exceptions, any products using ATS' technology for medical care and
     treatment of skin tissue wounds, such as pressure and venous ulcers, burns
     and skin tissue defects. The Dermagraft Joint Venture was further expanded
     in August 1998 by giving S&N the exclusive right to market TransCyte as a
     temporary covering for full and partial thickness burns in the United
     States, beginning in October 1998. Under the terms of the Dermagraft Joint
     Venture agreements, ATS is responsible for supervising the manufacturing of
     Dermagraft and TransCyte. S&N's existing wound care sales force and
     distribution network is used to market the products.

     As consideration for entering into the Dermagraft Joint Venture, S&N paid
     ATS $10 million in 1996. In connection with the 1998 expansion of the joint
     venture, S&N and ATS entered into the Purchase Agreement pursuant to which
     S&N purchased 1,533,115 shares of ATS Common Stock. The Dermagraft Joint
     Venture agreements also provide for certain payments by S&N to ATS upon the
     achievement of certain milestones. The first of these payments, $15
     million, was made in January 1999 and up to an additional $136 million may
     be payable in the future. Except for $10 million in regulatory approval and
     reimbursement milestones related to Dermagraft in the treatment of diabetic
     foot ulcers, all other approval, reimbursement and sales milestones are
     subject to, and payable from, joint venture earnings exceeding certain
     minimum levels. ATS and S&N will share equally in the expenses and revenues
     of the Dermagraft Joint venture except, as provided in the expansion
     agreements, ATS will fund the first $6 million of expenses for conducting
     clinical trials and for regulatory support of Dermagraft and TransCyte in
     the treatment of venous and pressure ulcers as well as certain
     manufacturing and distribution costs and certain costs related to
     post-market studies of TransCyte through December 1999. Pursuant to the
     Dermagraft Joint Venture

                                        8



     agreements, each of S&N and ATS has certain rights or obligations to
     purchase the other's interest under certain circumstances.

     In connection with the Dermagraft Joint Venture, Parent and ATS each own
     50% of DermEquip, L.L.C. ("DermEquip"). In August 1997, DermEquip entered
     into a term loan agreement with The Chase Manhattan Bank to borrow up to
     $16 million (the "Chase Loan") through June 1998. During the first half of
     1998, DermEquip completed drawdowns under the loan agreement to a total of
     $16 million. Principal is payable in equal quarterly installments from June
     1998 through June 2004. The Chase Loan bears interest payable quarterly at
     the 90-day London Interbank Offered Rate ("LIBOR") plus 1/4 percent (5.56%
     at December 31, 998). DermEquip's obligations with respect to the Chase
     Loan are jointly and severally guaranteed by Parent and ATS. The guarantees
     are secured by DermEquip's assets, having a carrying value of $14,485,000
     as of December 31, 1998, and by each of Parent's and ATS' interest in
     DermEquip.

     In 1994, S&N and ATS entered into a separate fifty-fifty joint venture for
     the worldwide development, manufacture and marketing of human-based,
     tissue-engineered cartilage for orthopedic applications (the "NeoCyte Joint
     Venture"). Under the agreement, S&N contributed the first $10 million in
     the NeoCyte Joint Venture funding and ATS contributed certain technology
     licenses. Revenues and expenditures of the NeoCyte Joint Venture after the
     first $10 million are being shared equally by the partners. In addition,
     S&N provided ATS with a $10 million loan commitment to fund ATS' share of
     the expenditures of the NeoCyte Joint Venture. This loan has been paid off,
     as provided in Item 3 above. The NeoCyte Joint Venture also has the right
     of first negotiation to develop tissue-engineered bone, tendon and ligament
     for orthopedic applications.

     On October 10, 2002, ATS and certain of its subsidiaries (the "ATS
     Entities") filed a voluntary petition for reorganization under Chapter 11
     of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the
     Southern District of California (the "Filing"). As part of the Filing, ATS
     filed a Section 363 motion to allow S&N to purchase the ATS Entities'
     equity interests in the Dermagraft Joint Venture and DermEquip and related
     assets (the "Sale") pursuant to an Asset and Equity Purchase Agreement
     among the ATS Entities, S&N and T. J. Smith & Nephew Limited (the "Sale
     Agreement") for a purchase price of $10 million in cash and the assumption
     of certain liabilities. The Sale Agreement also contemplates that the
     parties will agree to cease operations of the NeoCyte Joint Venture and
     enter into agreements whereby each of S&N and its affiliates and the ATS
     Entities will have non-exclusive rights to the technology and intellectual
     property of the NeoCyte Joint Venture. If the Sale is approved by the
     bankruptcy court, the parties anticipate closing the transactions
     contemplated in the Sale Agreement as soon as practicable (subject to any
     required regulatory approvals).

     In addition, the Filing also includes a proposed Loan and Security
     Agreement pursuant to which S&N would lend up to $5 million to the ATS
     Entities as "debtor-in-possession" financing to finance the operations of
     the ATS Entities and the Dermagraft Joint Venture pending the Sale. Any
     funds so loaned would be offset against the purchase price contemplated by
     the Sale Agreement. The S&N proposed financing and the Sale are subject to
     approval by the bankruptcy court. S&N would fund the proposed financing and
     the Sale from capital

                                        9



contributions or loans from its parent company. The parent company expects to
provide any funds necessary from working capital.
