ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

     As previously announced in a Form 8-K filed on September 9, 2009 (the
"September 9 Form 8-K"), on September 4, 2009, Spire Corporation (the
"Company"), Spire Biomedical, Inc., a wholly owned subsidiary of the Company
("Seller," and together with the Company, "Spire"), and Bard Access Systems,
Inc. ("Bard"), entered into an Asset Purchase Agreement (the "Purchase
Agreement") pursuant to which Bard has agreed to (i) acquire substantially all
of the assets of Spire's hemodialysis catheter business and (ii) assume and pay
post-closing liabilities related to the purchased assets as set forth in the
Purchase Agreement (collectively, the "Transaction").

     As disclosed in the September 9 Form 8-K, under the original terms of the
Purchase Agreement, such agreement could have been terminated by either Spire or
Bard if the closing had not occurred by September 30, 2009. On September 25,
2009, Spire and Bard entered into a letter agreement extending such outside
closing date from September 30, 2009 to October 31, 2009.

     A more complete description of the terms of the Purchase Agreement and the
Transaction may be found in the September 9 Form 8-K, which is incorporated
herein by reference.
