 CO-OPERATIVE DEVELOPMENT & SUPPLY AGREEMENT  



This
Co-operative Development & Supply Agreement ("Agreement") is hereby entered into between:

A123 Systems, Inc.

8 Saint Mary's Street

6th Floor

Boston, MA 02215

("A123") 


and 


Black &
Decker (U.S.), Inc.

701 East Joppa Road 

Towson, MD 21286, USA 

("B&D") 


(each
a "Party" and collectively the "Parties") 


The
effective date of this Agreement shall be September 15, 2004 (the "Effective Date"). 


In
consideration of the mutual covenants and promises contained herein, and for other good and valuable consideration, the Parties agree as follows: 


PROJECT 


        Lithium-Ion Cells—A123 has developed and manufactured a lithium-ion cell, which A123 and B&D believe
can be newly developed into a design which is commercially acceptable to B&D. 



        1.1    Development    Accordingly, B&D desires that A123 develop a
lithium-ion cell, which incorporates such changes in design made pursuant to the terms of this Agreement as will ensure, to the extent practicable, that the developed cell is commercially
acceptable to B&D. The lithium-ion cell to be developed ("CELL PRODUCT") is described in the preliminary specification ("SPECIFICATION") attached hereto as  Appendix "A" and made a part hereof.
A123 shall use its commercially reasonable best efforts to design a CELL PRODUCT that meets the
SPECIFICATION. The SPECIFICATION may be amended from time to time by written agreement of the Parties. 


        1.2    A123 to Supply PRODUCTS—    



        (a)   Subject to Section 1.2(b), in the event that the CELL PRODUCTS meet the SPECIFICATION, B&D may determine to
commercially introduce one or more B&D PRODUCTS (as defined below) to the market and upon such determination, A123 shall serve as a supplier of a battery pack incorporating the CELL PRODUCTS (a "PACK
PRODUCT;" The CELL PRODUCTS and PACK PRODUCTS are sometimes collectively referred to hereinafter as "PRODUCTS.") to B&D, subject to the terms of this Agreement and any Purchase Agreements which may
subsequently be entered into by the Parties. Should B&D choose to purchase only CELL PRODUCTS from A123 it will compensate A123 with a sum which is $[**] per PACK PRODUCT for
which A123 would have been entitled to supply under this agreement. A "B&D PRODUCT" shall be defined as a DEWALT branded professional power tool designed by or on behalf of B&D which incorporates the
CELL PRODUCT or the PACK PRODUCT. If the CELL PRODUCTS meet the SPECIFICATION

and
B&D does decide to introduce a DEWALT branded professional power tool with a lithium-ion battery, then subject to B&D's rights not to introduce a B&D PRODUCT pursuant to
Section 1.2(b) below, B&D will purchase PRODUCTS from A123 in accordance with the provisions of this Agreement. 


        (b)   Notwithstanding the foregoing Section 1.2(a), B&D shall not be required to commercially introduce a B&D PRODUCT to
the market, if (i) the commercial introduction of such B&D PRODUCT would be in violation of any applicable law, regulation or industry-wide guideline related to
lithium-ion products or (ii) the introduction of a B&D PRODUCT by B&D is commercially unreasonable due to safety and health hazards associated with the use of CELL PRODUCT, PACK
PRODUCT or B&D PRODUCT, or (iii) B&D, in its reasonable discretion determines that there are valid commercial reasons for it to not introduce the B&D PRODUCTS into the market, including but not
limited to technological advances in the market that render the B&D PRODUCTS obsolete or that are substantially superior in cost or performance. 



        (i)    If
an alternative lithium-ion battery is available to B&D in the market, such that B&D determines not to introduce the B&D PRODUCTS pursuant to
Section 1.2(b)(iii) above, that is comparable or superior to the CELL PRODUCTS and PACK PRODUCTS in specification, safe as determined by B&D, and at a significantly lower cost (a "Lower Cost
Battery"), B&D shall notify A123 and A123 will be required to close the cost differential and offer the PACK PRODUCTS and CELL PRODUCTS to B&D at a price that is within [**]%
of the cost of the Lower Cost Battery within [**] of the date of notification by B&D. If A123 cannot or is not willing to lower the pricing (not including the Exclusivity Fees
set forth in Section 4.6) of the CELL PRODUCTS and PACK PRODUCTS to within [**]% of the price of the Lower Cost Battery, B&D shall have the option to purchase such Lower
Cost Batteries from the alternative supplier, and if B&D does replace the PACK PRODUCTS and/or CELL PRODUCTS with the Lower Cost Battery, to terminate this Agreement in its entirety. If B&D does elect
to terminate this Agreement hereunder, B&D shall pay to A123 the sum of $[**], and A123 shall have no further remedy against B&D with respect to such termination. 


        (ii)   If
an alternative lithium-ion battery is available to B&D in the market, such that B&D determines not to introduce the B&D PRODUCTS pursuant to
Section 1.2(b)(iii) above, that is safe as determined by B&D's evaluation, and superior enough in performance to the CELL PRODUCTS and the PACK PRODUCTS to place B&D at a competitive
disadvantage in the market, as reasonably determined by B&D (a "Superior Battery"), B&D shall notify A123 and A123 will be required to close the performance differential so that the CELL PRODUCTS and
PACK PRODUCTS maintain competitive market performance, within [**] of the date of notification by B&D. During the time period that A123 is working toward such performance
improvements, B&D shall be permitted to purchase the Superior Batteries from a third party, and such purchases shall count towards the required volume of CELL PRODUCTS or PACK PRODUCTS to be purchased
hereunder in order for B&D to maintain its exclusivity rights (as set forth in Article IV). If A123 cannot or is not willing to improve the performance of the CELL PRODUCTS and PACK PRODUCTS
within [**] from the date of notification by B&D, B&D shall have the option to purchase the Superior Batteries from the alternative supplier and if B&D does replace the PACK
PRODUCTS and/or CELL PRODUCTS with the Superior Batteries, to terminate this Agreement in its entirety. If B&D does elect to terminate this Agreement hereunder, B&D shall pay to A123 the sum of
$[**], and A123 shall have no further remedy against B&D with respect to such termination.

        (c)   B&D acknowledges that it is its current intent to develop four B&D PRODUCTS, with a capitalization of
$[**], as approved by B&D's Chief Executive Officer. A123 understands, however, that the development of such B&D PRODUCTS is subject to B&D's standard design and milestone
process and B&D may determine, at any point during such design and milestone process, not to move forward with the development of a B&D PRODUCT. If B&D does determine not to move forward with such
development, B&D shall promptly notify A123, and this Agreement shall terminate in its entirety. Furthermore, B&D may decide to introduce DEWALT branded professional power tools into the market with
new battery technology other than lithium-ion (to the exclusion of lithium-ion); upon such a determination, B&D may terminate the Agreement in its entirety Upon a termination
of this Agreement as set forth in this Section 1.2(c), B&D shall not be required to pay any amount to A123, nor shall A123 have any further remedy against B&D with respect to such termination. 




        1.3   Initial Payment—Prior to the execution of this Agreement by
the Parties, B&D paid to A123 the non-refundable sum of [**] Dollars ($[**]. 


        1.4   Three-Phase Project—It is contemplated that the development
of the PRODUCTS will be accomplished in three phases. During such phases, A123 shall use its commercially reasonable best efforts to design a battery cell that meets the SPECIFICATION. The three
phases are as follow: 



        (a)   Phase 1 (Cell Design and
Prototyping).    [**], A123 shall use its commercially reasonable best efforts to build [**] prototype/pilot aluminum
26650 cells that meet the SPECIFICATION requirements ("the Aluminum Prototype PRODUCT"), by December 10, 2004. 



        (1)   Within [**] after delivery to B&D, B&D will test the Aluminum Prototype PRODUCTS to confirm that
they meet the SPECIFICATION. B&D shall provide promptly to A123 copies of all test results on the PRODUCTS and prototypes. Within [**] of such confirmation, B&D shall pay to
A123 a further non-refundable sum of [**] Dollars ($[**]. B&D shall notify A123 if the Aluminum Prototype PRODUCTS do not meet the
SPECIFICATION. In such case, A123 shall continue development of the Aluminum Prototype PRODUCTS at A123's expense until the Aluminum Prototype PRODUCTS meet the SPECIFICATION. 


        (2)   Phase 2 (Battery Pack Design and Prototyping)—A123 shall use its commercially reasonable best efforts
to build and provide to B&D, [**] prototypes of a battery pack sample in accordance with the SPECIFICATION ("the Battery Pack Samples") by April 1, 2005. Within
[**] after delivery to B&D, B&D will test the Battery Pack Samples to confirm that they meet the SPECIFICATION within [**] of such confirmation, B&D
shall advance A123 a further non-refundable sum of [**] Dollars ($[**]. B&D shall notify A123 if the Battery Pack Samples do not meet the
SPECIFICATION. In such case, A123 shall continue development of the Battery Pack Samples at A123's expense until the Battery Pack Samples meet the SPECIFICATION. 




        (b)   Phase 3 (Bulk Production)—Upon confirmation by B&D
that the Aluminum Prototype Products and the Battery Pack Samples meet the SPECIFICATION, B&D and A123 agree to negotiate in good faith and enter into a Purchase Agreement, in substantially the form
attached hereto as Exhibit B, for the purchase by B&D of PRODUCTS from A123. Such Purchase Agreement shall include pricing and volumes as
mutually agreed upon by the Parties. In connection with the Purchase Agreement, A123 will procure equipment, tooling and other articles so as to be able to manufacture the volume of commercially
acceptable PRODUCTS set forth in the Purchase Agreement. 




3







 


        (c)   Exclusivity During Project—During the development process of
the PRODUCTS pursuant to this Section 1.4, A123 shall not offer or provide lithium based energy sources or any of its intellectual property related thereto to any other companies whose business
is the manufacture,
marketing or development of products in the Power Tool Field and/or one or more of the Adjacent Fields, as defined in Section 3.1 below. 




        1.5    Delays in Bulk Purchase    



        (a)   B&D
shall purchase commercially acceptable PRODUCTS in bulk by September 1, 2005, or, if later, promptly after A123 delivers commercially acceptable PRODUCTS.
A123 agrees to use its commercially reasonable best efforts to deliver commercially acceptable PRODUCTS by September 1, 2005. The Parties acknowledge, however, that B&D's bulk purchase may be
delayed for a variety of reasons. If B&D issues its first purchase order for the bulk purchase of commercially acceptable PRODUCTS on or before December 1, 2005, B&D shall incur no monetary
penalty. If the issuance of B&D's first purchase order for the bulk purchase of commercially acceptable PRODUCTS is delayed until after December 1, 2005, B&D may be required to make an
additional payment to A123, subject to Section 1.5(b) below. The length of the delay will be calculated by (A) counting the number of
months between September 1, 2005 and the date of the issuance of B&D's first purchase order for the bulk purchase and prompt shipment of commercially acceptable PRODUCTS, and
(B) subtracting from that number the number of months (or parts thereof) of which A123 failure to meet the enumerated deadlines set forth herein has caused a delay in B&D's ability to purchase
PRODUCTS . The sum of clause (A) and (B) shall equal the "Total Delay." In calculating the Total Delay, partial months shall be rounded up to the next highest whole number of months. 



        (b)   If
the Total Delay is more than [**] but not more than [**], B&D shall pay to A123 [**] Dollars
($[**] for each [**] over [**]; if the Total Delay is more than [**] but not more than
[**], B&D shall pay to A123 an additional [**] Dollars ($[**] for each [**] over
[**]; and if the Total Delay is greater than [**], B&D shall pay to A123 [**] Dollars ($[**] and the
Parties agree to negotiate in good faith to determine how best to resolve the situation. Payment for any [**] shall be made promptly after the end of each such
[**].

        4.2   Exclusive Supply for Second Year—Subject to the provisions of
Section 4.5 below, during the second 12 -month period, B&D agrees to purchase from A123 at least [**] percent ([**]%) of the PACK PRODUCTS
required by B&D for the Power Tool Field. During the second 12-month period of bulk purchases of commercially acceptable PACK PRODUCTS by B&D from A123, A123 agrees that it will sell the
PACK PRODUCTS only to B&D for use in the Power Tool Field and Adjacent Fields (subject to the requirements of Article III above and Section 4.8 below), so long as: 



        (a)   B&D provides A123 with copies of the capitalization and milestone documents showing the progress of new products to be
powered with the A123 cells by August 2005 or prior to the issuance of B&D's first purchase order for a bulk purchase, whichever is later. These documents are to provide evidence of the projected unit
volumes, which project an A123 annual requirement of not less than [**] PACK PRODUCTS for the second production year 


        (b)   B&D purchases at least [**] PACK PRODUCTS during the first full year of bulk production. If B&D
fails to purchase such amount, B&D can maintain at its option the exclusivity for the second year of bulk production so long as B&D pays to A123 a sum which is [**]% of the
difference between the purchase price for [**] PACK PRODUCTS and the purchase price of the number of PACK PRODUCTS actually purchased during the first year of bulk production.
The payment shall include the additional Exclusivity Fees as defined in Section 4.6 below that would have been paid had B&D purchased [**] PACK PRODUCTS during the first
full year of bulk production; 


        (c)   B&D commits to purchase from A123 at least [**] PACK PRODUCTS; for the second production year 


        (d)   For the [**] period of the second year of bulk production, B&D must purchase at least

[**]% of the difference between the purchase price of [**] percent ([**]%) of the minimum total annual requirements of
the PACK PRODUCTS and the purchase price of the number of PACK PRODUCTS actually purchased during the [**] period of the second year of bulk production and (2) the
additional Exclusivity Fees that would have been paid had B&D purchased [**] percent ([**]%) of the minimum total annual requirements of the PACK
PRODUCTS in such [**] period. For the [**] period of the second year of bulk production, B&D must purchase at least
[**] percent ([**]%) of its minimum total annual requirements of the PACK PRODUCTS in order to maintain the exclusivity for the
[**] period of the third year of bulk production. If B&D has not purchased at least [**] percent ([**]%) of its minimum
total annual requirements of the 




6







 





PACK
PRODUCTS during the [**] period of the second year of bulk production, in order to maintain the exclusivity for the [**] period of the third year,
B&D at its option may pay to A123 (1) a sum which is [**]% of the difference between the purchase price of [**] percent
([**]%) of the minimum total annual requirements of the PACK PRODUCTS and the purchase price of the number of PACK PRODUCTS actually purchased during the
[**] period of the second year of bulk production and (2) the additional Exclusivity Fees that would have been paid had B&D purchased
[**] percent ([**]%) of the minimum total annual requirements of the PACK PRODUCTS in such [**] period;

payments to B&D within [**] days after the end of the second year. 




        4.3   Exclusive Supply for Third Year—Subject to the provisions of
Section 4.5 below, during the third 12 -month period, B&D agrees to purchase from A123 at least [**] percent ([**]%) of the PACK PRODUCTS
required by B&D for the Power Tool Field. During the third 12-month period of bulk purchases of commercially acceptable PACK PRODUCTS by B&D from A123, A123
agrees that it will sell the PACK PRODUCTS only to B&D for use in the Power Tool Field and Adjacent Fields (subject to the requirements of Article III above and Section 4.8 below) so
long as: 



        (a)   B&D has met the obligations and requirements of Section 4.2(d) above; 


        (b)   B&D provides A123 by [**] with (1) copy of the capitalization and milestone documents
showing the progress of new products to be powered with the A123 cells, and (2) the marketing plans and projections for B&D products powered by the A123 cells launched within
[**] of B&D's original bulk purchase of commercially acceptable PACK PRODUCTS. These documents are to provide evidence of the projected unit volumes, which project an A123
annual requirement of not less than [**] PACK PRODUCTS for the third production year; 


        (c)   B&D commitment to purchase from A123 at least [**] of its PACK PRODUCTS during the third year of
bulk production. 


        (d)   For the [**] period of the third year of bulk production, B&D must purchase at least

[**] period of the third year of bulk production. If B&D has not purchased at least [**] percent ([**]%) of its minimum
total annual requirements of the PACK PRODUCTS during the [**] period of the third year, B&D shall be able to maintain the exclusivity for the [**]
period of the third year by paying to A123 (1) a sum which is [**]% of the difference between the purchase price of [**] percent
([**]%) of the minimum total annual requirements of the PACK PRODUCTS and the purchase price of the number of PACK PRODUCTS actually purchased by B&D during the
[**] period of the third year and (2) the additional Exclusivity Fees that would have been paid had B&D purchased [**] percent
([**]%) of the minimum total annual requirements of the PACK PRODUCTS in such [**] period; 


For
the [**] period of the third year of bulk production, B&D must purchase at least [**] percent ([**]%) of its minimum
total annual requirements of the PACK PRODUCTS in order to maintain the exclusivity for the [**] period of the fourth year. If B&D has not purchased at least
[**] percent ([**]%) of its minimum total annual requirements of the PACK PRODUCTS during the [**] period of the third
year, in order to maintain the exclusivity for the [**] period of the fourth year, B&D at its option may pay to A123 (1) a 




7







 





sum
which is [**]% of the difference between the purchase price of [**] percent ([**]%) of the minimum total annual
requirements of the PACK PRODUCTS and the purchase price of the number of the PACK PRODUCTS actually purchased during the [**] period of the third year and (2) the
additional Exclusivity Fees that would have been paid had B&D purchased [**] percent ([**]%) of the minimum total annual requirements of the PACK
PRODUCTS in such [**] period. 


        (e)   If B&D ultimately purchases in the aggregate in the [**] periods of the third year at least
[**] of the PACK PRODUCTS, and B&D has paid to A123 any payments pursuant to Sections 4.3(d) to maintain exclusivity during the third year, A123 shall return such
payments to B&D within [**] days after the end of the third year. 




        4.4   Exclusive Supply for Subsequent Years—B&D and A123 agree to
negotiate in good faith, on a timely basis, the minimum annual requirements for maintaining the exclusivity in subsequent years. 



        4.5   Non-Exclusive Supply to B&D—If B&D does not
maintain the exclusivity of supply by A123 pursuant to Sections 4.1 to 4.4 above, A123 shall be free to supply any products to third parties for use in any field, and will still supply PRODUCTS
to B&D pursuant to the terms of the Purchase Agreement, on a non-exclusive basis. If B&D does not maintain the exclusivity of supply by A123 pursuant to Sections 4.1 to 4.4 above,
B&D may, at its option, terminate this Agreement and any Purchase Agreement between the parties, by providing eighteen (18) months written notice to A123. 



        4.6   Exclusivity Fee—During the period of supply exclusivity under
Sections 4.1 to 4.4 above, B&D shall pay an additional [**] ($[**]) per cell as an Exclusivity Fee. For any 12-month period of bulk
production described in Sections 4.1 to 4.4 above, the Exclusivity Fee shall be lowered to [**] ($[**]) per cell for the remainder of such
12-month period after B&D has purchased [**] percent ([**]%) of its committed volume for any such 12-month
period (i.e., [**]% of the minimum total annual requirements for PACK PRODUCTS). 


        4.7   Escrowed Information—A123 shall have a second qualified
manufacturing source of the PRODUCTS in place by January 1, 2006. A123 shall provide B&D on or prior to March 1, 2005 a contingency plan for the manufacture of the cell powder materials,
including placing information sufficient for B&D to manufacture the cells and cell powder materials in escrow ("the Escrowed Information"). The Escrowed Information shall be reviewed by an independent
firm chosen by B&D and approved by A123 (who shall not unreasonably withhold such approval) to confirm that the Escrowed Information is sufficient to manufacture the cells and cell powder materials.
Such independent firm shall not disclose any of the Escrowed Information to B&D and shall only report to B&D whether the Escrowed Information is sufficient to manufacture the cells and cell powder
materials. In the event the Escrowed Information is insufficient to manufacture the cells and cell powder materials, A123 shall supplement the Escrowed Information as necessary. A123 shall maintain
the Escrowed Information up to date. The Escrowed Information (and a license to use such information) will be made available to B&D during the term of this Agreement and any Purchase Agreements
entered into by the Parties in the event that A123 ceases operations, is unable to supply B&D with the required number of cells meeting B&D's delivery or quality requirements as set forth in the
Purchase Agreement(s) between the parties, or is unwilling to meet its obligations hereunder. To the extent that A123 is unable to meet its obligations under this Agreement, A123 will actively
cooperate with B&D to remedy such shortfalls. B&D's license to make or have made cells and cell powder materials according to the Escrowed Information will expire within [**]
from receipt of a notification from A123 that A123 is able to supply B&D with the required number of cells meeting B&D's delivery and quality requirements, as set forth in the Purchase Agreement(s)
between the parties. Such [**] period is intended to allow the phase-out of 



8







 




the
B&D or third party manufacture and the phase-in of A123 manufacture. The parties shall negotiate in good faith any extensions of the phase-out/phase-in period
due to B&D's commercial necessities. B&D shall pay to A123 $[**] per cell manufactured by B&D or a third party designated by B&D under this Section. 



        4.8   Possible Supply in Adjacent Fields—B&D agrees to coordinate

  AMENDMENT TO COOPERATIVE DEVELOPMENT
  AND
  SUPPLY AGREEMENT    
    


        THIS AMENDMENT TO COOPERATIVE DEVELOPMENT AND SUPPLY AGREEMENT (this "Amendment") is
made effective as of the 18th day of August, 2005, by and between Black & Decker (U.S.) Inc., a Maryland corporation ("B&D"), A123
Systems, Inc., a Delaware corporation ("A123"). 


 
 

  R E C I T A L S    
    


        A.    B&D and A123 have entered into a Cooperative Development and Supply Agreement (the "Agreement"), dated as of
January 20, 2005, pursuant to which the parties are developing a lithium-ion cell for commercial production. Capitalized terms used herein and not otherwise defined shall have the
meaning given to them in the Agreement. 


        B.    Subject
to the terms of the Agreement, B&D was to begin purchasing PRODUCTS in bulk by September 1, 2005, or, if later, promptly after A123 delivers commercially
acceptable PRODUCTS. The parties now desire to increase the planned purchase volumes from a maximum of [**] PRODUCTS per month to [**] PRODUCTS per
month. In order to begin bulk purchases earlier and to increase its production capacity, A123 will be required to invest approximately $[**] in additional capital in new
tooling and equipment, and B&D is willing to loan such amount to A123. 


        C.    The
parties desire to amend the Agreement, subject to the terms and conditions contained herein. 



        NOW, THEREFORE, in consideration of the mutual premises, representations, covenants and agreements herein contained, and other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 


1.    Tooling.    Promptly after the execution of this Amendment, A123 will place an order to purchase the additional tooling
required to manufacture the PRODUCTS (the "New Tooling"), and will send to B&D an invoice equal to the amount of the purchase price of the New Tooling, or approximately US$[**]
(the "Loan Amount"). Within [**] days after B&D's receipt of such invoice, B&D will pay to Al23 the Loan Amount. All such New Tooling shall be and shall remain the property of
B&D until the Loan Amount is repaid to B&D in accordance with the terms of this Amendment. It shall be plainly identified by A123 as "Property of Black & Decker (U.S.) Inc." and shall be
safely stored and not used except in filling B&D's orders hereunder. The property, while in A123's custody, shall be maintained in good condition, normal wear and tear accepted, at A123's expense and
shall be kept insured by A123 at A123's expense in an amount equal to the replacement cost, with loss payable to B&D. A123 shall furnish to B&D a certificate of insurance evidencing A123's compliance
with the provisions of this Section 1. B&D's property may be removed by B&D at any time in accordance with Paragraph 5 below, in the event that A123 is in material breach of any of the
provisions of the Agreement, this Amendment, or any Purchase Agreement entered into by A123 and B&D or any affiliated B&D entity, and such material breach is not cured within
[**] days of written notice thereof. Immediately upon repayment or satisfaction of the Loan Amount by A123, all such tooling shall become the property of A123 and at the
request of A123 and without further consideration, B&D shall execute and deliver such instruments of sale, transfer, conveyance and assignment and take such actions as A123 may reasonably request to
more effectively transfer, convey and assign to A123, and to confirm A123's rights to, title in and ownership of, all such tooling and to place A123 in actual possession and operating control thereof. 


1







 

2.    Repayment of Loan Amount.



        a.     Beginning
[**] after A123's receipt of written authorization from B&D to initiate bulk production of the PRODUCTS, A123 promises to pay to B&D the
Loan Amount, as described below: 




i.    When
B&D's Average Run Rate (as defined below) reaches [**] PRODUCTS per [**], A123 shall pay to B&D [**]% of
the Loan Amount, or approximately US$[**]. 


ii.    When
B&D's Average Run Rate reaches [**] PRODUCTS per [**], A123 shall pay to B&D an additional [**]% of the
Loan Amount, or US$[**]. 


iii.    When
B&D's Average Run Rate reaches [**] PRODUCTS per [**], A123 shall pay to B&D an additional [**]% of Loan
Amount, or US$[**]. 


iv.    When
B&D's Average Run Rate reaches [**] PRODUCTS per [**], A123 shall pay to B&D the final [**]% of Loan
Amount, or US$[**]. 





        b.     B&D's
"Average Run Rate" shall mean, for periods beginning [**] after the initiation of bulk purchases by B&D, B&D's average of the
[**] purchases of PRODUCTS over the previous [**] and the forecasted purchases for the upcoming [**]. 


        c.    All
payments required to made above shall be made by A123 by check or by wire transfer of immediately available funds, to B&D at 701 E. Joppa Road, Towson, Maryland
21286, Attention:                                    or to an account
designated by B&D, by the [**] in which B&D achieves the Average Run Rates set forth above. 




3.    Notwithstanding
the foregoing Section 2, beginning [**] after A123's receipt of written authorization from B&D to initiate bulk production of the
PRODUCTS, in any [**] during which A123 is using the New Tooling and A123 has not yet repaid the Loan Amount in full, B&D will receive a credit equal to
$[**] per PRODUCT, for each PRODUCT in excess of [**] PRODUCTS that it purchases from A123 during such [**]. The aggregate
credit received by B&D from A123 will be subtracted from the amount of the Loan Amount to be repaid from time to time, when B&D achieves the Average Run Rates set forth above. 


4.    In
consideration for the foregoing, A123 agrees that the exclusive supply period set forth in Section 4.3 of the Agreement shall be extended for an additional
[**] period, so that, assuming that B&D complies with all other provisions of Section 4.3 regarding maintaining exclusivity, at the end of the second
[**] period of the third
year of bulk production, A123 shall, for an additional [**] period, sell the PACK PRODUCTS for use in the Power Tool Field and Adjacent Fields only to B&D and to no other
entity, no matter where located. 


5.    In
the event that B&D elects to remove it's property from A123 pursuant to its right to do so set forth in Paragraph 1 above, then: 



        a.     B&D
shall provide A123 with [**] days' prior written notice of such proposed removal; 


        b.    in
the event that B&D desires to sell such property to a third party, 



        i.    B&D
shall do so through an agent and maintain in confidence the identity of A123 and B&D and the specific use of the property, and 



        ii.    B&D
shall provide A123 with a right of first refusal to purchase the property on the same terms and conditions available to any bona fide third party desiring to
purchase the property. 





6.    In
the event of any conflict between the terms of this Amendment and the terms of the Agreement, this Amendment shall control. Except as amended herein, all provisions of the Agreement
shall remain in full force and effect.

  AMENDMENT TO

COOPERATIVE DEVELOPMENT & SUPPLY AGREEMENT  


        THIS AMENDMENT TO COOPERATIVE DEVELOPMENT & SUPPLY AGREEMENT (the "Amendment") is made effective as of
September             , 2007, by and between A123 Systems, Inc., a Delaware corporation, with offices at The Arsenal on the Charles, 321 Arsenal Street, Watertown, MA 02472
("Contractor"), and Black & Decker (U.S.) Inc., a Maryland corporation, of 701 East Joppa Road, Towson, Maryland 21286 ("Black & Decker"). 


EXPLANATORY STATEMENT  


        A.    The
parties hereto have entered into a Cooperative Development & Supply Agreement, dated as of September 15, 2004, as amended by an Amendment dated
August 18. 2005, an Amendment dated July 1, 2006, and an Amendment dated March, 2007 (together, the "CDSA"), pursuant to which the parties have developed a lithium-ion cell
for commercial production. Capitalized terms used herein but not defined shall have the meaning given to them in the CDSA. 


        B.    The
CDSA defines the fields in which Black & Decker has the exclusive right to sell Pack Products or Cell Products. The parties now desire to amend the Agreement
so that Black & Decker will waive its Right of First Refusal in the Adjacent Field with respect to the opportunity for development of a [**] (as defined below) and will
permit A123 to sell Pack Products or Cell Products into an Adjacent Field for the same opportunity, subject to certain restrictions, all as set forth below. 


        NOW,
THEREFORE, in consideration of the Explanatory Statement, the mutual covenants and promises contained herein, and other good and valuable consideration, the receipt of and
sufficiency of which are hereby acknowledged, the parties hereto agree to amend the Agreement as follows: 



        1.     For
purposes of this Amendment, a [**] shall be defined as a [**] having a total [**]; shall  not include a [**]; shall not have [**]; shall  not have a [**] (shall not be a [**]); and shall not be a [**]. 


        2.     Pursuant
to Section 3.2 of the CDSA, A123 has approached Black & Decker with a reasonable business proposal regarding the development and sale of cells into
the Adjacent Field of [**]. Specifically, A123 desires to develop and manufacture cells for an [**] ("Manufacturer") for Manufacturer's use with its
[**]. Black & Decker hereby waives its Right of First Refusal with respect to this opportunity and agrees that A123 may develop and manufacture cells for Manufacturer
for use with its [**], subject to the terms and conditions set forth in this Amendment. 


        3.     A123
agrees that: 


        (a)   any
intellectual property associated with cell developments that is developed and owned solely by A123 in connection with the development of cells for Manufacturer for
use with its [**] ("New IP") shall first be made available to Black & Decker for use consistent with Black & Decker's rights under the CDSA before A123 offers
such New IP for the use of any other entity (other than Manufacturer). 


        (b)   A123
will not enter into any exclusivity agreements with Manufacturer or any other entity related to the New IP, that would restrict Black & Decker's access to,
or ability to use, the New IP, or Black & Decker's ability to participate in the Adjacent Field of [**]. 


        (c)   the
selling price for any cells that A123 sells to Black & Decker for use in the Adjacent Field of [**] shall at no time exceed the lowest
price at which such cells are offered to any of A123's other customers purchasing in like quantities and terms. In the event that, prior to the shipment under Black & Decker's purchase order,
A123 sells or offers to sell cells to the Manufacturer at lower prices and or on terms more favorable than those stated in Black & Decker's purchase order, A123 shall notify Black &
Decker of the same and the prices and or terms herein shall be deemed automatically revised to equal the lowest price and or most favorable terms at which A123 shall have sold or shall have offered
such cells and payments shall be made accordingly. In the event Black & Decker shall become entitled to such lower prices but shall have made payment at any price in excess thereof, A123 shall
promptly credit the difference in price to Black & Decker. 







 

        4.     In
consideration for Black & Decker's agreements hereunder, A123 further agrees that Black & Decker shall receive an annual credit towards its annual
requirement of purchases under Article IV of the CDSA, equal to [**] Pack Products. This credit shall be applied by A123 to Black & Decker's purchases during each
12-month period used by the Parties to determine if Black & Decker has met its obligations with respect to maintaining exclusivity, as set forth in Article IV of the CDSA. 



        5.     Except
as amended hereby, all other provisions of the CDSA shall remain in full force and effect. 


        IN
WITNESS WHEREOF, the undersigned have executed and delivered this Amendment to Cooperative Development & Supply Agreement as of the day and year set forth above.

 AMENDMENT TO THE

CO-OPERATIVE DEVELOPMENT & SUPPLY AGREEMENT  



This
Amendment to the Co-operative Development & Supply Agreement ("Amendment") is hereby entered into between: 


A123
Systems, Inc.

The Arsenal on the Charles

321 Arsenal Street

Watertown, MA 02472 ("A123") 


and 


Black &
Decker (U.S.), Inc.

701 East Joppa Road

Towson, MD 21286, USA

("B&D") 


(each
a "Party" and collectively the "Parties") 


The
effective date of this Amendment shall be December 19, 2007 (the "Effective Date"). 



 RECITALS:  



1.    The
Parties entered into a Cooperative Development & Supply Agreement effective as of September 15, 2004, as subsequently amended on August 18, 2005,
July 1, 2006, and March 30, 2007, respectively, (collectively, the "CDSA"), pursuant to which A123 developed certain CELL PRODUCTS (as defined therein) for B&D. Capitalized terms used
herein and not otherwise defined shall have the meaning given to them in the CDSA. 


2.    The
Parties now desire to amend and supplement the CDSA, to modify certain provisions, including without limitation, the Exclusivity provisions in Article IV that govern the
calculation of B&D's purchase requirements and exclusivity payments, on the terms and conditions set forth herein. 




        NOW THEREFORE, In consideration of the mutual covenants and promises contained herein, and for other good and valuable consideration, the
Parties agree as follows: 


	1.
	The
CDSA is hereby amended and supplemented as follows: 



A.
Section 4.6.    Delete Section 4.6 in its entirety and replace it with the following new Section 4.6: 



4.6    Exclusivity Fee—(a) During the period of supply exclusivity under Sections 4.1 to 4.4 above, B&D shall pay an
additional [**] ($[**]) per 26650 CELL and [**]($[**]) per 18650 CELL as an Exclusivity Fee (subject to
subparagraph (c) of this Section 4.6 below), which shall be calculated based on the applicable Cell count per PACK PRODUCT as illustrated below. 


(b)    For
purposes of determining if B&D has met its obligations under Sections 4.2, 4.3 and 4.4 with respect to minimum volume purchases to maintain exclusivity, credit will be
given for PACK PRODUCTS being purchased based on the following: a PACK PRODUCT containing [**] 26650 Cells at $[**] each or
$[**] total, or a PACK PRODUCT containing [**] 18650 Cells at $[**] each or $[**] total, will each be
equal to one unit. The following examples are provided for purposes of illustrating how the foregoing calculation metric will be applied: 



Example 1:


[**]
cell Omega3 pack (using 18650 Cells) will be worth [**] in exclusivity payments

[**]Therefore each Omega3 pack will count towards [**]% of a PACK PRODUCT unit 



Example
2: 


[**]
cell [**] pack (using 18650 Cells) will be worth [**]in exclusivity payments 











[**]
Therefore, each [**] pack will counts towards [**] PACK PRODUCT units 




(c)    The
parties agree that as of the Effective Date, B&D may determine whether or not it will pay the Exclusivity Fee on the Cells it purchases from A123 for certain applications provided
that B&D shall
promptly notify A123 in writing of such determination. If B&D determines that it will not pay the Exclusivity Fee for Cell purchases for such specific applications, then no credit toward PACK PRODUCT
units purchased for purposes of maintaining exclusivity will be given to B&D for the Cells purchased for that application. An example is the current [**] program whereby B&D
does not to pay the $[**] exclusivity fee on the Cells for that application. Therefore, the [**] will be excluded from counting towards PACK PRODUCT
exclusivity volume requirements. The foregoing shall not change, and shall have no impact on, the existing applications for which B&D currently pays the non-refundable Exclusivity Fee or
the definition of the Fields in which B&D maintains exclusivity under Article IV. 




2.    Within
[**] days after the end of each month during the term of the Agreement, A123 shall invoice B&D for the Exclusivity Fee due based on net purchases made by
B&D in the prior month, and shall provide the following supporting information: (a) Number of Cells purchased by B&D directly from A123, (b) Number of Cells A123 has shipped and invoiced
to STL or such other third party pack manufacturer identified by B&D, and (c) Number of Cells returned to A123 by STL or such other third party pack manufacturer identified by B&D, and credited
back. Payments of the Exclusivity Fee shall be due by B&D to A123 within [**] days after B&D's receipt of the invoice. 


3.    Except
as amended hereby, the CDSA is hereby ratified by the Parties and shall continue in full force and effect. This Amendment, together. with the CDSA, contains the entire agreement
of the Parties hereto and supersedes all earlier agreements and understandings, oral and written, between the Parties hereto with respect to the subject matter hereof. 


The
Parties have caused this Amendment to be executed by their respective authorized representatives as of the Effective Date.
