 WARRANT TO PURCHASE STOCK  


Company:
A123 Systems, Inc.

Number of Shares: 7,416 SVB, subject to adjustment

Class of Stock: Series C Convertible Preferred Stock

Warrant Price: $3.371016, subject to adjustment

Issue Date: August 2, 2006

Expiration Date: August 1, 2013

Credit Facility:    This Warrant is issued in connection with that certain Term Loan and Security Agreement of even date herewith between Silicon Valley Bank, Gold Hill Venture and the
Company. 


        THIS
WARRANT CERTIFIES THAT, for good and valuable consideration, SILICON VALLEY BANK, (Silicon Valley Bank, together with any successor or permitted assignee or transferee of this
Warrant or of any shares issued upon exercise hereof, is referred to hereinafter as "Holder") is entitled to purchase the number of fully paid and nonassessable shares (the "Shares") of the class of
securities (the "Class") of the above-named company (the "Company") at the above-stated Warrant Price, all as set forth above and as adjusted pursuant to Article 2 of this Warrant, subject to
the provisions and upon the terms and conditions set forth in this Warrant. 


ARTICLE
1.    EXERCISE.  


        1.1    Method of Exercise.    Holder may exercise this Warrant by delivering the original of this Warrant together
with a duly executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is exercising the conversion right set forth in
Article 1.2, Holder shall also deliver to the Company a check, wire transfer (to an account designated by the Company), or other form of payment acceptable to the Company for the aggregate
Warrant Price for the Shares being purchased. 


        1.2    Conversion Right.    In lieu of exercising this Warrant as specified in Article 1.1, Holder may from
time to time convert this Warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair market value of one Share. The fair market value of the Shares shall be determined pursuant to
Article 1.3. 


        1.3    Fair Market Value.    If the Company's common stock is traded in a public market and the Shares are common
stock, the fair market value of a Share shall be the closing price of a share of common stock reported for the business day immediately before Holder delivers this Warrant together with its Notice of
Exercise to the Company (or in the instance where the Warrant is exercised immediately prior to the effectiveness of the Company's initial public offering ("IPO"), the "price to public" per share
price specified in the final prospectus relating to such offering). If the Company's 










common
stock is traded in a public market and the Shares are preferred stock, the fair market value of a Share shall be the closing price of a share of the Company's common stock reported for the
business day immediately before Holder delivers this Warrant together with its Notice of Exercise to the Company (or, in the instance where the Warrant is exercised immediately prior to the
effectiveness of the Company's IPO, the initial "price to public" per share price specified in the final prospectus relating to such offering), in both cases, multiplied by the number of shares of the
Company's common stock into which a Share is then convertible. If the Company's common stock is not traded in a public market, the Board of Directors of the Company shall determine fair market value
in its reasonable good faith judgment. 


        1.4    Delivery of Certificate and New Warrant.    Promptly after Holder exercises or converts this Warrant and, if
applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for the Shares acquired and, if this Warrant has not been fully exercised or
converted and has not expired, a new Warrant representing the Shares not so acquired. 


        1.5    Replacement of Warrants.    On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the
case of mutilation, or surrender and cancellation of this Warrant, the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor. 


        1.6    Treatment of Warrant Upon Acquisition of Company.    



        1.6.1    "Acquisition".    For the purpose of this Warrant, "Acquisition" means any sale, license, or other
disposition of all or substantially all of the assets of the Company, or any reorganization, consolidation, merger or sale of outstanding capital stock of the Company where the holders of the
Company's securities before the transaction beneficially own less than a majority of the outstanding voting securities of the surviving entity after the transaction. 


        1.6.2    Treatment of Warrant at Acquisition.    



	A)
	Upon
the written request of the Company, Holder agrees that, in the event of an Acquisition (other than a True Asset Sale (as defined below)) in which the
sole consideration is cash, either (a) Holder shall exercise its conversion or purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation
of such Acquisition or (b) if Holder elects not to exercise the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide the Holder with written
notice of its request relating to the foregoing (together with such reasonable information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which
is to be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition.



	B)
	Upon
the written request of the Company, Holder agrees that, in the event of an Acquisition that is an "arms length" sale of all or substantially all of the
Company's assets (and only its assets) to a third party that is not an Affiliate (as defined below) of the Company (a "True Asset Sale"), either (a) Holder shall exercise its conversion or
purchase right under this Warrant and such exercise will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to exercise the Warrant, this
Warrant will continue until the Expiration Date if the Company continues as a going concern following the closing of any such True Asset Sale. The Company shall provide the Holder with written notice
of its request relating to the foregoing (together with such reasonable information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which shall
be delivered to Holder not less than ten (10) days prior to the closing of the proposed Acquisition.



	C)
	Upon
the closing of any Acquisition other than those particularly described in subsections (A) and (B) above, the successor entity shall assume
the obligations of this Warrant, and this Warrant shall be exercisable for the same securities, cash, and property as would be payable for the Shares issuable upon exercise of the unexercised portion
of this Warrant as if such Shares were 








outstanding
on the record date for the Acquisition and subsequent closing. The Warrant Price and/or number of Shares shall be adjusted accordingly. 




As
used herein "Affiliate" shall mean any person or entity that owns or controls directly or indirectly ten percent (10%) or more of the stock of
Company, any person or entity that controls or is controlled by or is under common control with such persons or entities, and each of such person's or entity's officers, directors, joint venturers or
partners, as applicable. 



        1.6.3    Certain Acquisitions.    Notwithstanding Section 1.6.2 above, in the event that the acquirer in an
Acquisition (other than an acquisition in which the consideration received by the Company's stockholders consists solely of cash and/or cash equivalents) does not agree to assume this Warrant at
and as of the closing thereof, this Warrant, to the extent not exercised or converted on or prior to such closing, shall terminate and be of no further force and effect as of immediately following
such closing if all of the following conditions are met: (i) the acquirer is subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of
1934, as amended, (ii) the class of stock or other security of the acquire that would be received by Holder in connection with such Acquisition were Holder to exercise or convert this Warrant
on or prior to the closing thereof is listed for trading on a national securities exchange or approved for quotation on an automated inter-dealer quotation system, (iii) the value (determined
as of the closing of such Acquisition in accordance with the definitive agreements therefor) of the acquirer stock and/or other securities that would be received by Holder in respect of each Share
were Holder to exercise or convert this Warrant on or immediately prior to the closing of such Acquisition is equal to or greater than 3.5 times the then-effective Warrant Price,
(iv) Holder would be able to publicly resell all of the acquirer stock and/or other securities that would be received by Holder in such Acquisition were Holder to exercise or convert this
Warrant on or prior to the closing of such Acquisition during the three (3) month period immediately following the closing thereof pursuant to an effective registration statement under the
covering such acquiror stock and/or other securities or pursuant to the provisions of Rule 144 under the Act, and (v) the Company provides the Holder with written notice of such
Acquisition relating to the foregoing (together with such reasonable information as the Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is
received by the Holder not less than ten (10) days prior to the closing of the proposed Acquisition. 




ARTICLE
2.    ADJUSTMENTS TO THE SHARES.  


        2.1    Stock Dividends, Splits, Etc.    If the Company declares or pays a dividend on the outstanding shares of the
Class payable in common stock or other securities, then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares of record as of the date the dividend occurred. If the Company subdivides the outstanding shares of the Class by reclassification or
otherwise into a greater number of shares or takes any other action which increase the amount of common stock into which the one share of the Class is convertible, the number of Shares purchasable
hereunder shall be proportionately increased and the Warrant Price shall be proportionately decreased. If the outstanding shares of the Class are combined or consolidated, by reclassification or
otherwise, into a lesser number of shares, the Warrant Price shall be proportionately increased and the number of Shares shall be proportionately decreased. 



        2.2    Reclassification, Exchange, Combinations or Substitution.    Upon any reclassification, exchange, substitution,
or other event that results in a change of the number and/or class of the securities issuable upon exercise or conversion of this Warrant, Holder shall be entitled to receive, upon exercise or
conversion of this Warrant, the number and kind of securities and property that Holder would have received for the Shares if this Warrant had been exercised immediately before such reclassification,
exchange, substitution, or other event. Such an event shall include, without limitation, any automatic conversion of the outstanding or issuable securities of the Company of the same class or series
as the Shares to common stock pursuant to the terms of the Company's Articles or Certificate (as applicable) 










of
Incorporation upon the closing of the IPO. The Company or its successor shall promptly issue to Holder an amendment to this Warrant setting forth the number and kind of such new securities or other
property issuable upon exercise or conversion of this Warrant as a result of such reclassification, exchange, substitution or other event that results in a change of the number and/or class of
securities issuable upon exercise or conversion of this Warrant. The amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant.
The provisions of this Article 2.2 shall similarly apply to successive reclassifications, exchanges, substitutions, or other events. 


        2.3    Adjustments for Diluting Issuances.    The Warrant Price and the number of shares of common stock issuable upon
conversion of the Shares shall be subject to adjustment, from time to time in the manner set forth in the Company's Articles or Certificate of Incorporation as if the Shares were issued and
outstanding on and as of the date of any such required adjustment. The provisions set forth for the Shares, in the Company's Articles or Certificate (as applicable) of Incorporation relating to the
above in effect as of the Issue Date may not be amended, modified or waived, without the prior written consent of Holder unless such amendment, modification or waiver affects the rights associated
with the Shares in the same manner as such amendment, modification or waiver affects the rights associated with all other shares of the same series and class as the Shares granted to the Holder. 


        2.4    No Impairment.    The Company shall not, by amendment of its Articles or Certificate (as applicable) of
Incorporation or through a reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or
performance of any of the terms to be observed or performed under this Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this
Article 2 and in taking all such action as may be necessary or appropriate to protect Holder's rights under this Article against impairment. 


        2.5    Fractional Shares.    No fractional Shares shall be issuable upon exercise or conversion of the Warrant and the
number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise or conversion of the Warrant, the Company shall eliminate such
fractional share interest by paying Holder the amount computed by multiplying the fractional interest by the fair market value of a full Share. 


        2.6    Certificate as to Adjustments.    Upon each adjustment of the Warrant Price, the Company shall promptly notify
Holder in writing, and, at the Company's expense, promptly compute such adjustment, and furnish Holder with a certificate of its Chief Financial Officer setting forth such adjustment and the facts
upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth the Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price. 


ARTICLE
3.    REPRESENTATIONS AND COVENANTS OF THE COMPANY.  


        3.1    Representations and Warranties.    The Company represents and warrants to, and agrees with, the Holder as

        (a)   The
initial Warrant Price referenced on the first page of this Warrant is not greater than the price per share at which shares of the same class and series as the Shares
were last issued in an arms-length transaction in which at least $500,000 of such shares were sold. 


        (b)   All
Shares which may be issued upon the exercise of the purchase right represented by this Warrant, and all securities, if any, issuable upon conversion of the Shares,

distribution upon the outstanding shares of the same class and series as the Shares, whether in cash, property, stock, or other securities and whether or not a regular cash dividend; (b) to
effect any reclassification, reorganization or recapitalization of any of its stock; or (c) to effect an Acquisition or to
liquidate, dissolve or wind up, then, in connection with each such event, the Company shall give Holder: (1) at least 10 days prior written notice of the date on which a record will be
taken for such dividend or distribution (and specifying the date on which the holders of shares of the same class and series as the Shares will be entitled thereto) or for determining rights to vote,
if any, in respect of the matters referred to in (c) and (d) above; and (2) in the case of the matters referred to in (b) and (c) above at least 10 days prior

of the Company until the exercise of this Warrant. 


        3.5    Certain Information.    The Company agrees to provide Holder at any time and from time to time with such
information as Holder may reasonably request for purposes of Holder's compliance with regulatory, accounting and reporting requirements applicable to Holder. 



ARTICLE
4.    REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE HOLDER.    The Holder represents and
warrants to the Company as follows: 


        4.1    Purchase for Own Account.    This Warrant and the securities to be acquired upon exercise of this Warrant by
Holder will be acquired for investment for Holder's account, not as a nominee or agent, and not with a view to the public resale or distribution within the meaning of the Act. Holder also represents
that it has not been formed for the specific purpose of acquiring this Warrant or the Shares. 



        4.2    Disclosure of Information.    Holder has received or has had full access to all the information it considers
necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity to ask questions
and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent the Company
possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder has access. 













































  
        4.3    Investment Experience.    Holder understands that the purchase of this Warrant and its underlying securities
involves substantial risk. Holder has experience as an investor in securities of companies in the development stage and acknowledges that Holder can bear the economic risk of such Holder's investment
in this Warrant and its underlying securities and has such knowledge and experience in financial or business matters that Holder is capable of evaluating the merits and risks of its investment in this
Warrant and its underlying securities and/or has a preexisting personal or business relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration
that enables Holder to be aware of the character, business acumen and financial circumstances of such persons. 


        4.4    Accredited Investor Status.    Holder is an "accredited investor" within the Meaning of Regulation D
promulgated under the Act. 


        4.5    The Act.    Holder understands that this Warrant and the Shares issuable upon exercise or conversion hereof
have not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder's investment intent as
expressed herein. Holder understands that this warrant and the Shares issued upon any exercise or conversion hereof must be held indefinitely unless subsequently registered under the 1933 Act and
qualified under applicable state securities laws, or unless exemption from such registration and qualification are otherwise available. 


        4.6    Lock-Up Agreement.    The Holder, if requested by the Company and the managing underwriter of the
Company's IPO, agrees not to sell or otherwise transfer or dispose of any securities of the Company held by the Holder for a period specified by the managing underwriter not to exceed 180 days
following the effective date of the registration statement for such IPO; and the Holder agrees to execute a "lock-up" agreement with the Company and the managing underwriter of such IPO
confirming such agreement if requested by the Company; provided that: (i) such lock-up and agreements set forth in this Section 4.6 shall only apply to the initial public
offering of common stock of the Company to be sold by or on behalf of the Company in an underwritten offering, and (ii) all stockholders of the Company then holding at least 5% of the
outstanding common stock (on an as-converted basis) of the Company and all officers and/or directors of the Company enter into similar agreements and are not released, in whole or part,
from such lock-up obligations in connection with such IPO. 


ARTICLE
5.    MISCELLANEOUS.  



        5.1    Term:    This Warrant is exercisable in whole or in part at any time and from time to time on or before the
Expiration Date. 


        5.2    Legends.    This Warrant and the Shares (and the securities issuable, directly or indirectly, upon conversion
of the Shares, if any) shall be imprinted with a legend in substantially the following form: 




THIS
WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER THE ACT, OR THE SECURITIES LAWS OF ANY STATE AND, EXCEPT AND PURSUANT TO THE PROVISIONS OF ARTICLE 5 OF THAT CERTAIN
WARRANT TO PURCHASE STOCK ISSUED BY THE COMPANY TO SILICON VALLEY BANK DATED AS OF AUGUST 2, 2006 MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED
UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAW OR, IN THE OPINION OF LEGAL COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR
HYPOTHECATION IS EXEMPT FROM REGISTRATION. 





        5.3    Compliance with Securities Laws on Transfer.    This Warrant and the Shares issuable upon exercise of this
Warrant (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) may not be transferred or assigned in whole or in part without compliance with 








applicable
federal and state securities laws by the transferor and the transferee (including, without limitation, the delivery of investment representation letters and legal opinions reasonably
satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the transfer is to SVB Financial Group (Holder's parent
company) or any other affiliate of Holder, provided that any such transferee is an "accredited investor" as defined in Regulation D promulgated under the Act. 



        5.4    Transfer Procedure.    After receipt by Silicon Valley Bank ("Bank) of the executed Warrant, Bank will transfer
all of this Warrant to SVB Financial Group, Holder's parent company, by execution of an Assignment substantially in the form of Appendix 2. Subject to the provisions of Article 5.3 and
upon providing the Company with written notice, SVB Financial Group and any subsequent Holder may transfer all or part of this Warrant or the Shares issuable upon exercise of this Warrant (or the
Shares
issuable directly or indirectly, upon conversion of the Shares, if any) to any transferee, provided, however, in connection with any such transfer, SVB Financial Group or any subsequent Holder will
give the Company notice of the portion of the Warrant being transferred with the name, address and taxpayer identification number of the transferee and Holder will surrender this Warrant to the
Company for reissuance to the transferee(s) (and Holder if applicable). The Company may refuse to transfer this Warrant or the Shares to any person who directly competes with the Company, unless, in
either case the stock of the Company is publicly traded.

deemed delivered and effective when given personally or mailed by first-class registered or certified mail, postage prepaid, at such address as may have been furnished to the Company or Holder, as the
case may (or on the first business day after transmission by facsimile) be, in writing by the Company or such holder from time to time. All notices to Holder shall be addressed as follows until the
