ITEM 1.02     TERMINATION OF A MATERIAL DEFINITIVE AGREEMENT.

MANUFACTURING AGREEMENT WITH PRINCIPIA LIGHTWORKS, INC.
-------------------------------------------------------

     On August 29, 2008, Spire  Semiconductor,  LLC ("Spire  Semiconductor"),  a
wholly-owned  subsidiary  of  Spire  Corporation  (the  "Company"  or  "Spire"),
delivered to Principia  Lightworks,  Inc.  ("Principia")  a Notice of Breach and
Pending Termination (the "Notice") of a certain Manufacturing  Agreement,  dated
August  29,  2006,  by  and  between  Spire  Semiconductor  and  Principia  (the
"Manufacturing Agreement").

     Under the terms of the Manufacturing  Agreement, for a period commencing in
the first quarter of 2007 and continuing until May 31, 2012, Spire Semiconductor
was to be the exclusive  supplier to Principia of III/V and II/VI  semiconductor
wafers to be used by  Principia  to  fabricate  electron  beam-pumped,  vertical
cavity,  surface emitting lasers (eVCSEL).  Under the terms of the Manufacturing
Agreement,  Principia made an up-front payment for nonrecurring  engineering and
facility  access costs and, in addition  was  required to make monthly  facility
availability payments throughout the term of the agreement.

     As a  result  of  Principia's  failure  to  make  recent  monthly  facility
availability  payments  totaling  $300,000,  Spire  Semiconductor  delivered the
Notice,  notifying  Principia  that if  Principia  fails to make  such  past due
payments,  as well as the payment due for the month of  September,  by September
29, 2008, then Spire  Semiconductor  is electing to terminate the  Manufacturing
Agreement,  effective  September 30, 2008.  In accordance  with the terms of the
Manufacturing  Agreement,  upon termination of the Agreement, in addition to the
past due  payments,  Principia  would  also owe Spire  Semiconductor  all unpaid
future monthly facility availability payments, totaling $3.15 million.

     In the  event  Principia  fails  to  adequately  cure  the  default,  Spire
Semiconductor  intends to take title to up to 67,500 shares of Principia  common
stock in its possession  pledged to Spire  Semiconductor  to secure  Principia's
first eighteen  facility  payments (of which Principia has not paid $300,000) as
required under the Manufacturing  Agreement. The remaining facility payments are
unsecured.  At the time the Manufacturing  Agreement was executed,  these shares
were intended to have an aggregate market value of $1,350,000;  however, because
Principia  is a private  company,  the  current  actual  value of such shares is
unknown at this time.

     At the time of the agreement,  Spire  Semiconductor  scaled-up its existing
metal organic chemical vapor deposition  (MOCVD) capacity and related processing
facilities  to  satisfy  Principia's  requirements.  At that time,  the  Company
anticipated  that the  up-front  payment  plus  the  monthly  payments  would be
sufficient to meet its capital  requirements  under the agreement.  In exchange,
Spire  Semiconductor  granted  Principia  first  priority  with  respect  to the
expanded manufacturing capacity.

     Termination of the Manufacturing  Agreement will disencumber  manufacturing
capacity  allowing  Spire  Semiconductor  to freely  enter  high  volume  supply
contracts  with  other   customers  for   alternative   markets  such  as  solar
concentrator  cells.  Spire  Semiconductor   continues  to  discuss  alternative
business arrangements to further develop Principia's laser technology.


DEVELOPMENT, MANUFACTURING AND SALES CONSORTIUM AGREEMENT WITH NISSHINBO
------------------------------------------------------------------------
INDUSTRIES, INC.
---------------

     On September 1, 2008,  Nisshinbo  Industries,  Inc ("Nisshinbo") served the
Company  a  letter   stating  its  intention  to  terminate   the   Development,
Manufacturing,  and Sales Consortium  Agreement (the  "Agreement")  entered into
between the Company and Nisshinbo on May 16, 2005. Pursuant to Article

                                       2


12.1 of the  Agreement,  Nisshinbo  is  providing  its 180 day  prior  notice to
terminate the Agreement effective as of February 28, 2009.

     The  Company  entered  into the  10-year  Agreement  on May 16,  2005  with
Nisshinbo,  headquartered in Tokyo,  Japan, for the development,  manufacturing,
and sales of solar photovoltaic module manufacturing equipment.  Under the terms
of the Agreement,  Nisshinbo  purchased a permanent  license to manufacture  and
sell  Spire  module  manufacturing  equipment  for  an  undisclosed  amount  and
additional  royalties over the ten-year term. Spire and Nisshinbo also agreed to
pursue  joint  research and  development,  and product  improvement  activities.
Worldwide  marketing  and  sales  were to be a joint  effort  with  Pacific  Rim
emphasis by  Nisshinbo  and  Western  Hemisphere  emphasis  by Spire.  Currently
Nisshinbo  manufactures  laminators  for the Company  and the  Company  receives
royalties based upon Nisshinbo sales to third parties.

     Under  the terms of the  Agreement,  early  termination  by  Nisshinbo  for
convenience  entitles Spire to a termination  penalty  payment of  approximately
$5.8 million.  Upon all payments being satisfied,  Spire shall grant Nisshinbo a
perpetual,  royalty-free,   non-exclusive  license  to  Spire's  existing  solar
photovoltaic module manufacturing  equipment methods of engineering,  designing,
manufacturing  and other  related  methods  that were in effect when the Company
entered into the  Agreement.  The Company and  Nisshinbo are in  discussions  on
concluding the Agreement,  including alternative manufacturing  arrangements and
technology  license  agreements   concerning   technology  developed  under  the
Agreement.
