                                SPIRE CORPORATION
                           FORM 8-K/A, AMENDMENT NO. 1

     The undersigned Registrant hereby amends its Current Report on Form 8-K,
dated May 27, 2003, to include Item 2, amend and restate Item 7 and file the
financial statements and pro forma financial information required by Item 7.

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

     On May 23, 2003 Spire Corporation (the "Company") acquired from Stratos
Lightwave, Inc. ("Seller") all of the ownership interests of Bandwidth
Semiconductor, LLC ("Bandwidth"), a Delaware limited liability company, located
in Hudson, New Hampshire. Bandwidth is a compound semiconductor foundry
providing material and device fabrication services to defense,
telecommunications and biomedical instrument industries. The total purchase
price was $954,351 in cash, including acquisition costs of $229,385, plus
liabilities assumed of $3,044,244. The Company's acquisition of Bandwidth did
not include the following "excluded assets": various forms of cash held by
Bandwidth, and the proceeds of the sale of real estate in Hudson, New Hampshire
owned and partly occupied by Bandwidth. The cash used by the Company to acquire
Bandwidth came from the Company's cash assets. The consideration from the
Company to Seller included the release and forgiveness from all future
obligations of Bandwidth, Seller and Methode Electronics, Inc., the former
parent of Stratos, in connection with a Sublease Agreement with the Company
dated December 29, 1999 and expiring on November 30, 2005 for approximately
21,275 square-feet of space previously occupied by Bandwidth in Bedford,
Massachusetts. As a result, the Company recorded a $1,247,241 assumed liability
in the purchase accounting representing the present value of the remaining lease
obligation associated with the unused space. The acquisition of Bandwidth,
including the purchase price, was negotiated at arm's length between the Company
and the Seller. Neither the Company nor any director or officer of the Company
was affiliated with, or had a material relationship with, the Seller.

     Among the assets owned by Bandwidth is an Emcore E-300LDM Growth Pump
System reactor (the "System"). Bandwidth uses the System for metal organic
chemical vapor deposition ("MOCVD") film growth. The System is the subject of a
Master Lease Agreement, which requires monthly payments to General Electric
Capital Corporation of approximately $36,411 through September 15, 2004. After
the initial three-year period ending in September 2004, the lease allows for an
additional two-year extension. The Company expects to extend the lease term for
the additional two years to September 2006. The lease has a residual value
guarantee of $204,000 at the end of the extended period. This lease has been
accounted for as a capital lease and a $1,430,311 assumed liability was recorded
in the purchase accounting representing the present value of the remaining lease
obligations through 2006 including the buyout amount.

     In conjunction with the acquisition of Bandwidth by the Company, SPI-Trust,
a Trust of which Roger G. Little, Chairman of the Board, Chief Executive Officer
and President of the Company, is sole trustee and principal beneficiary,
purchased from Stratos the building that Bandwidth occupies in Hudson, New
Hampshire for $3.7 million. Subsequently, the Company entered into a lease for
the building (90,000 square-feet) with SPI-Trust whereby the Company will pay
$4.1 million to the SPI-Trust over the initial five-year term expiring in 2008
with a Company option to extend for five years. The lease agreement does not
provide for a transfer of ownership at any point. This lease was recorded by
Spire as a related party capital lease on the acquisition date. As of such date,
Bandwidth occupied approximately 40,000 square-feet of space in the building,
including class 100/1000 clean rooms of approximately 13,000 square-feet. The
Company believes that for the foreseeable future, Bandwidth will continue to
occupy approximately the same amount of space, including clean rooms, as it
occupied before May 23, 2003.
