ASPEN AEROGELS, INC.




COMMON STOCK PURCHASE WARRANT



 





          This document (this “Warrant”) certifies that, for good and valuable consideration, Aspen
Aerogels, Inc., a Delaware corporation (the “Company”), grants to [IMPORT WARRANTHOLDER] (the
“Warrantholder”), the right to subscribe for and purchase from the Company, on or before [IMPORT
EXPIRATION TIME] (the “Expiration Time”), an aggregate of [IMPORT SHARE NUMBERS] validly issued,
fully paid and nonassessable shares of Common Stock (the “Warrant Shares”), at the exercise price
per share of $4.423 (the “Exercise Price”), all subject to the terms, provisions, conditions and
adjustments (including adjustments to number of shares and Exercise Price) herein set forth. The
Company acknowledges that the cash consideration paid by Warrantholder for this Warrant is $10.00
for income tax purposes, that such amount has been duly received by the Company, and that this
Warrant is issued in connection with that certain financial accommodation entered into by and
between Company as the obligor and Warrantholder as the obligee thereunder (the “Financing
Arrangement”) and that this Warrant amends and restates all warrants previously issued to the
Warrantholder in connection with the Financing Arrangement. Capitalized terms used herein which
are not specifically defined in other sections of this Warrant, shall have the meanings set forth
in Section 11.



          1. Warrant Term. The purchase rights represented by this Warrant are
exercisable, in whole or in part, at any time and from time to time, from and after the Warrant
grant date of [IMPORT GRANT DATE], and on or prior to the earlier of the (i) Expiration Time, or
(ii) in the event of a Corporate Event.



 









 





          2. Exercise of Warrant; Payment of Taxes.



          2.1 Exercise of Warrant. The purchase rights represented by this Warrant may be
exercised by the Warrantholder, in whole or in part and from time to time, by the surrender of this
Warrant (with a duly executed notice of exercise form, the “Exercise Form”, in the form attached
hereto as Exhibit A) at the principal office of the Company and by the payment to the
Company of an amount equal to the then applicable Exercise Price per share multiplied by the number
of Shares then being purchased. If the Warrantholder is not already a party thereto, the
Warrantholder shall also execute, upon request from the Company, a joinder agreement to the
Stockholder’s Agreement, as amended and restated, such joinder agreement to be in form and
substance mutually agreeable to both Warrantholder and Company. The Warrantholder shall be deemed
to have become the holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the Shares represented thereby (and such Shares shall be deemed to have been issued)
immediately prior to the close of business on the date or dates upon which this Warrant is
exercised.



          2.2 Non-Cash Exercise.





(a) In lieu of payment in cash, the rights represented by this Warrant may also be exercised
at any time by a written notice of exercise in the form of Exhibit A attached
hereto, providing for the non-cash exercise of this Warrant for the Shares equal to the
value (as determined below) of this Warrant (or the portion thereof being exercised),
specifying that this non-cash exercise election has been made, and the net number of Shares
to be issued after giving effect to such non-cash exercise. In the event the Warrantholder
makes such election, Company shall issue to the holder a number of shares computed using the
following formula:



	 	 	 	 	 

	X

	 	=
	 	Y(A-B)
	 

	 	 	 	A






Where:





X = the number of Shares to be issued to the holder




Y = the number of Shares purchasable under the Warrant or, if only a portion of the Warrant
is being exercised, the portion of the Warrant being exercised (as of the date of such
non-cash exercise)




A = the Fair Market Value of one Share of Common Stock (as of the date of such non-cash
exercise)




B = Exercise Price of one Share of Common Stock (as adjusted to the date of such non-cash
exercise)



     (b) For purposes of this Section 2.2, the “Fair Market Value” of one share of the
Company’s Common Stock shall be equal to either (i) if the exercise of this Warrant occurs in
connection with an initial public offering of the Company, then the Fair Market Value shall be
equal to the “initial price to public” specified in the final prospectus with respect to the
initial public offering, or (ii) if the exercise of this Warrant occurs after an initial public
offering of the Company but not in connection therewith, then the Fair Market Value shall be equal
to the average of the closing price(s) of the Company’s Common Stock as quoted over the counter or
on any exchange on which the Common Stock is listed as such closing prices are published in The
Wall Street Journal for the fifteen trading days (or such



 - 2 - 









 




lesser number of trading days as the stock may have been actually trading) ending on the day
prior to the date of determination of Fair Market Value. Notwithstanding the foregoing, if the
Warrant is exercised in connection with a merger or sale of all or substantially all of the
Company’s assets, Fair Market Value shall mean the value that would have been allocable to or
received in respect of a Warrant Share had the Warrant been exercised prior to such merger or sale.
If the Common Stock is not traded Over The Counter or on an exchange, or if the Warrant is not
exercised in connection with a merger or sale of all or substantially all of its assets, then the
Fair Market Value shall be determined in good faith by the Company’s board of directors. If the
holder hereof does not agree with the determination of Fair Market Value as determined by the
Company’s board of directors, the Company and the holder hereof shall negotiate an appropriate Fair
Market Value. If after ten (10) days, the Company and the holder cannot agree, then the holder may
request that the Fair Market Value be determined by an investment banker of national reputation
selected by the Company and reasonably acceptable to the Warrantholder. The fees and expenses of
such investment banker shall be borne by the Company unless the Fair Market Value determined by
such investment banker is equal to or less that the Fair Market Value as determined by the Company,
in which event the fees and expenses of such investment banker shall be borne by the holder hereof.




          2.3 Automatic Exercise. Immediately before the expiration or termination of this
Warrant, to the extent this Warrant is not previously exercised, and if the Fair Market Value of
one share of the Company’s Common Stock subject to this Warrant is greater than the Exercise Price,
then in effect as adjusted pursuant to this Warrant, this Warrant shall be deemed automatically
exercised pursuant to Section 2.2 above, even if not surrendered. For purposes of such automatic
exercise, the Fair Market Value of the Company’s Common Stock upon such expiration shall be
determined pursuant to Section 2.2 (b) above. To the extent this Warrant or any portion thereof is
deemed automatically exercised pursuant to this Section, the Company agrees to promptly notify the
Warrantholder of the number of Shares, if any, the holder hereof is to receive by reason of such
automatic exercise.




          2.4 Exercise in Connection with an Initial Public Offering, Sale or Merger.
Notwithstanding any other provision hereof, if the exercise of all or any portion of this Warrant
is made or to be made in connection with the occurrence of a public offering, sale or merger of the
Company, the exercise of all or any portion of this Warrant shall, at the election of the
Warrantholder, be conditioned upon the consummation of the public offering, sale or merger of the
Company in which case such exercise shall not be deemed to be effective until the consummation of
such transaction. In the event that transaction is not consummated within 45 days of the targeted
date of the transaction, any such exercise shall, at the election of the Warrantholder, be deemed
rescinded.




               2.5 Warrant Shares Certificate. A stock certificate for the Warrant Shares
specified in the Exercise Form shall be delivered to the Warrantholder within five (5) Business
Days after receipt of the Exercise Form by the Company and payment by the Warrantholder of the
aggregate Exercise Price (or non-cash exercise in lieu of payment as permitted in Section 2.2),
along with a check from the Company in lieu of any fractional shares which the Warrantholder would
be entitled to purchase under this Warrant. If this Warrant was exercised in part, the Company
shall, at the time of delivery of the stock certificate, deliver to the Warrantholder a new Warrant
evidencing the right to purchase the remaining Warrant Shares, which new Warrant shall in all other
respects be identical with this Warrant.



               2.6 Payment of Taxes. The Company shall pay all expenses, taxes and other
governmental charges with respect to the issue or delivery of the Warrant Shares, unless such tax
or charge is imposed by law upon the Warrantholder.

          3. Restrictions on Transfer; Restrictive Legends.



               3.1 Restrictions on Transfer. This Warrant and the Warrant Shares issuable upon
exercise of all or part of this Warrant are unregistered securities that are subject to the
restrictions on transfer imposed by the Securities Act and applicable state securities laws and may
not be offered, sold, transferred, pledged or otherwise disposed of, in whole or in part, to any
Person other than in accordance with the Securities Act and applicable state securities laws. The
Warrant Shares issuable upon exercise of all or part of this Warrant are also subject to additional
restrictions on transfer set forth in the Stockholders Agreement and may not be offered, sold,
transferred, pledged or otherwise disposed of, in whole or in part, to any Person other than in
accordance with the Stockholders Agreement.



               3.2 Restrictive Legends. Until such time as the restrictions on transfer imposed
on this Warrant by the Securities Act and applicable state securities laws shall no longer be
effective, this Warrant, any Warrant issued to the Warrantholder upon the partial exercise of this
Warrant pursuant to Section 2, and any Warrant issued to the Warrantholder in substitution
for this Warrant pursuant to Section 7 shall be stamped or otherwise imprinted with a
legend in substantially the form as set forth on the cover of this Warrant. Until such time as the
restrictions on transfer imposed on the Warrant Shares by the Securities Act, applicable state
securities laws and the Stockholders Agreement shall no longer be effective, each stock certificate
for Warrant Shares and each stock certificate issued upon the direct or indirect transfer of any
such Warrant Shares shall be stamped or otherwise imprinted with a legend in substantially the form
provided in the Stockholders’ Agreement. Upon the termination of such restrictions on transfer,
the Warrantholder may require the Company to issue a Warrant or a stock certificate for Warrant
Shares, in each case without a legend, if and to the extent permitted by, and in accordance with,
the Stockholders Agreement and applicable law.



          4. Reservation and Registration of Shares. The Company covenants and agrees as
follows:



               4.1 Validly Issued and Free of Encumbrances. All Warrant Shares issued upon the
exercise of all or any part of this Warrant shall, upon issuance and payment of the Exercise Price
therefore (or upon non-cash exercise as permitted herein), be validly issued, fully paid and
nonassessable, issued in compliance with all applicable federal and state securities laws, and free
from all taxes, liens and charges with respect to the issue thereof, and not subject to any
preemptive rights.



               4.2 Sufficient Authorized Shares. During the period within which the rights
represented by this Warrant may be exercised, the Company shall at all times have authorized and
reserved, for the purpose of issuance of Common Stock upon any exercise of the purchase rights
evidenced by this Warrant, and shall keep available free from preemptive rights, a sufficient
number of shares of its Common Stock to provide for the exercise of the rights represented by this
Warrant.



               4.3 Noncontravention. The Company shall not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, spin-off, consolidation, merger,
dissolution, issue or sale of securities or any other action or inaction, avoid or seek to avoid
the observance or performance of any of the terms of this Warrant to be observed or performed
hereunder, and shall at all times in good faith assist in performing, carrying out, and giving
effect to the terms hereof and in the taking of all such actions as may be necessary or appropriate
in order to protect the rights of the Warrantholder against dilution or other impairment.



 - 4 - 









 





          5. Anti-Dilution Adjustments. From and after the date hereof and until the
Expiration Date, notwithstanding the fact that no Warrant Shares shall be issued and outstanding,
the Exercise Price, and the number and type of Warrant Shares or other securities to be received
upon exercise of the Warrant, shall be subject to adjustment as follows:



               5.1 Dividend, Subdivision, Combination or Reclassification of Common Stock. If
the Company shall, at any time or from time to time, prior to exercise in full of this Warrant: (a)
pay a dividend or otherwise make a distribution on the outstanding shares of Common Stock payable
in Capital Stock; (b) subdivide the outstanding shares of Common Stock into a larger number of
shares; (c) combine the outstanding shares of Common Stock into a smaller number of shares; or (d)
issue any shares of its Capital Stock in a reclassification of the Common Stock (other than any
such event for which an adjustment is made pursuant to another clause of this Section 5),
then, and in each such case, the Exercise Price and the number of Warrant Shares exercisable
hereunder in effect immediately prior to such event shall be adjusted (and any other appropriate
actions shall be taken by the Company) so that the Warrantholder shall thereafter be entitled to
receive, upon the exercise of the unexercised portion of this Warrant, the number of shares of
Common Stock or other securities of the Company that such Warrantholder would have owned or would
have been entitled to receive upon or by reason of any of the events described above, had this
Warrant been exercised immediately prior to the occurrence of such event. An adjustment made
pursuant to this Section 5.1 shall become effective retroactively: (x) in the case of any
such dividend or distribution, to a date immediately following the close of business on the record
date for the determination of holders of Common Stock entitled to receive such dividend or
distribution; or (y) in the case of any such subdivision, combination or reclassification, to the
close of business on the day upon which such corporate action becomes effective.



               5.2 Issuance of Common Stock or Common Stock Equivalents below Exercise Price. If
the Company shall, at any time or from time to time, prior to exercise in full of this Warrant,
issue or sell any shares of Common Stock or Common Stock Equivalents at a “New Issue Price” (as
defined below) per share of Common Stock or Common Stock Equivalent that is less than the Exercise
Price then in effect as of the record date or Issue Date referred to in the following sentence, as
the case may be (the “Relevant Date”), other than issuances of Excluded Stock, then, and in each
such case, the Exercise Price then in effect shall be adjusted by multiplying the Exercise Price in
effect immediately prior to the Relevant Date by a fraction:




               (a) the numerator of which shall be the sum of the number of shares of Common Stock
outstanding on the Relevant Date (assuming conversion or exercise of all Common Stock
Equivalents into Common Stock) plus (i) in the case of Common Stock, the number of shares of
Common Stock which the aggregate consideration received by the Company for the total number
of such additional shares of Common Stock so issued would purchase at the Exercise Price on
the Relevant Date, or (ii) in the case of Common Stock Equivalents, the number of shares of
Common Stock which the aggregate amount of the consideration paid for, or the aggregate
exercise price of, such Common Stock Equivalents, plus any additional consideration payable
upon conversion, exchange or exercise of such Common Stock Equivalents, would purchase at
the Exercise Price on the Relevant Date; and




               (b) the denominator of which shall be the sum of (i) the number of shares of Common
Stock outstanding on the Relevant Date (assuming conversion or exercise of all Common Stock
Equivalents into Common Stock) plus (ii) the number of additional shares of Common Stock
issued or to be issued or, in the case of Common Stock Equivalents, the maximum number of
shares of Common Stock into which such Common Stock Equivalents initially may convert,
exchange or be exercised.



 - 5 - 









 





                    Such adjustment shall be made whenever such shares of Common Stock or Common Stock Equivalents
are issued, and shall become effective retroactively, in the case of an issuance to the
stockholders of the Company, as such, to a date immediately following the close of business on the
record date for the determination of stockholders entitled to receive such shares of Common Stock
or Common Stock Equivalents, and, in all other cases, on the date of such issuance (the “Issue
Date”); provided, however, that the determination as to whether an adjustment is required to be
made pursuant to this Section 5.2 shall only be made upon the issuance of such shares of
Common Stock or Common Stock Equivalents, and not upon the issuance of any security into which the
Common Stock Equivalents convert, exchange or may be exercised. For purposes of this Section
5.2, the “New Issue Price” of any shares of Common Stock shall be equal to the price per share
received by the Company upon the consummation of such sale and the “New Issue Price” of any Common
Stock Equivalents shall be equal to (x) the sum of (A) the price for such Common Stock Equivalent
plus (B) any additional consideration payable (without regard to any anti-dilution adjustments)
upon the conversion, exchange or exercise of such Common Stock Equivalent, divided by (y) the
number of shares of Common Stock initially underlying such Common Stock Equivalent.



               5.3 Certain Distributions. If the Company shall, at any time or from time to
time, prior to exercise in full of this Warrant, distribute to all holders of shares of the Common
Stock (including any such distribution made in connection with a merger or consolidation in which
the Company is the resulting or surviving Person and the Common Stock is not changed or exchanged)
cash, evidences of indebtedness of the Company or another issuer, securities of the Company or
another issuer or other assets or rights or warrants to subscribe for or purchase securities of the
Company (excluding those distributions in respect of which an adjustment in the Exercise Price is
made pursuant to another paragraph of this Section 5), then, and in each such case:




               (a) the Exercise Price then in effect shall be adjusted (and any other appropriate
actions shall be taken by the Company) by multiplying the Exercise Price in effect
immediately prior to the date of such distribution by a fraction, (i) the numerator of which
shall be the Current Market Price of the Common Stock immediately prior to the date of
distribution less the then fair market value (as determined by the Board of Directors in the
exercise of their fiduciary duties) of the portion of the cash, evidences of indebtedness,
securities or other assets so distributed or of such rights or warrants applicable to one
share of Common stock, and (ii) the denominator of which shall be the Current Market Price
of the Common Stock immediately prior to the date of distribution (but such fraction shall
not be greater than one); provided, however, that no adjustment shall be made upon such
distribution pursuant to this Section 5.3(a) if an adjustment is made upon such
distribution pursuant to Section 6; and




               (b) the number of Warrant Shares for which this Warrant is exercisable immediately
prior to such distribution shall be adjusted (and any other appropriate actions shall be
taken by the Company) by multiplying the then-current number of Warrant Shares in effect
immediately prior to the date of such distribution by a fraction, (i) the numerator of which
shall be the Exercise Price in effect immediately prior to immediately prior to the date of
distribution, and (ii) the denominator of which shall be the adjusted Exercise Price as
determined pursuant to clause (a) of this Section 5.3 (but such fraction
shall not be less than one); provided, however, that no adjustment shall be made upon such
distribution pursuant to this Section 5.3(b) if an adjustment is made upon such
distribution pursuant to Section 6.



               Such adjustments shall be made whenever any such distribution is made and shall become
effective retroactively to a date immediately following the close of business on the record date
for the determination of stockholders entitled to receive such distribution.



 - 6 - 









 





               5.4 Other Changes. INTENTIONALLY DELETED



               5.5 De Minimus Adjustments. Notwithstanding anything herein to the contrary, no
adjustment under this Section 5 need be made to the Exercise Price and the number of
Warrant Shares unless such adjustment would require an increase or decrease of at least one percent
(1%) of the Exercise Price then in effect. Any lesser adjustment shall be carried forward and
shall be made at the time of and together with the next subsequent adjustment which, together with
any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at
least one percent (1%) of such Exercise Price. Any adjustment to the Exercise Price and the number
of Warrant Shares carried forward and not theretofore made shall be made immediately prior to the
exercise of this Warrant.



               5.6 Notice of Adjustment under Section 5. The Company shall, no later than twenty
(20) Business Days prior to the occurrence of any event that would result in an adjustment pursuant
to this Section 5, provide the Warrantholder with a written notice describing such event in
reasonable detail and setting forth the Exercise Price and number of Warrant Shares, as adjusted as
a result of such event.



               5.7 Reclassification, Reorganization, Change or Conversion. In case of any
reclassification, reorganization, change or conversion of securities of the class issuable upon
exercise of this Warrant (other than a change in par value, or from par value to no par value, or
from no par value to par value, or as a result of a subdivision or combination), then in any of
these events, the Company shall execute a replacement warrant (a “New Warrant”), in form and
substance reasonably satisfactory to the holder of this Warrant, upon the exercise of which (and at
a total purchase price under the New Warrant not to exceed that payable upon the exercise in full
of this Warrant) the holder of the New Warrant shall receive, in lieu of each Share receivable upon
the exercise of this Warrant, the same kind and amount of shares of stock, other securities, money
and property receivable by a holder of one share of Common Stock upon such reclassification,
reorganization, change or conversion. Such New Warrant shall provide for adjustments that shall be
as nearly equivalent as may be practicable to the adjustments provided for in this Section 5. The
provisions of this section 5.7 shall similarly apply to successive reclassifications,
reorganizations, changes, or conversions.



               Whenever the Exercise Price shall be adjusted pursuant to the provisions of this Warrant, the
Company shall within ten (10) days of such adjustment deliver a certificate signed on behalf of the
Company by its chief financial officer to the Warrantholder setting forth, in reasonable detail,
the event requiring the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated, and the Exercise Price after giving effect to such adjustment.



          6. Intentionally Deleted.



          7. Exercise or Termination upon Corporate Event. The Company shall, no later than
twenty (20) Business Days prior to the anticipated consummation date of any Corporate Event,
provide the Warrantholder with a written notice describing such Corporate Event in reasonable
detail and setting forth the consideration (i.e., securities, cash and other property) receivable
for each share of Common Stock pursuant to such Corporate Event. If the aggregate Exercise Price,
as of such consummation date, is equal to or greater than the aggregate value of the securities,
cash and other property that would have been received in connection with Corporate Event by a
holder of the number of shares of Common Stock for which this Warrant was exercisable immediately
prior to such Corporate Event (the “Exercise Proceeds”), then this Warrant shall terminate upon the
consummation of such Corporate Event. If the aggregate Exercise Price, as of such consummation
date, is less than the aggregate value of the Exercise Proceeds, then the Warrantholder shall be
entitled to exercise this



 - 7 - 









 




Warrant in connection with such Corporate Event and shall automatically receive upon the
consummation of such Corporate Event, in lieu of the Warrant Shares, the Exercise Proceeds.




          8. Loss or Destruction of Warrant. Subject to the terms and conditions hereof,
upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, of such
bond or indemnification as the Company may reasonably require, and, in the case of such mutilation,
upon surrender and cancellation of this Warrant, the Company will execute and deliver to the
Warrantholder a new Warrant of like tenor.



          9. Ownership of Warrant. The Company may deem and treat the person in whose name
this Warrant is registered as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all purposes and shall not
be affected by any notice to the contrary, until presentation of this Warrant for registration of
transfer.



          10. Amendments. Any provision of this Warrant may be amended and the observance
thereof waived only with the written consent of the Company and the Warrantholder.

the Act.

and the Company’s charter documents and bylaws which have been furnished to Warrantholder or the
Warrantholder’s counsel reflect all amendments made thereto at any time prior to the date hereof
and are correct and complete.



          (c) With respect to the issuance of this Warrant or the issuance of the Common Stock upon
exercise of the Warrant, there are no statutory or contractual stockholders preemptive rights or
rights of refusal, except for any such rights contained in any stock purchase agreement and/or
investor’s rights agreements which have been waived. The Company has not violated any applicable
federal or state securities laws in connection with the offer, sale or issuance of any of its
capital stock, and the offer, sale and issuance of this Warrant does not require registration under
the Act or any applicable state securities laws. To the best of the Company’s knowledge, there are
no agreements between the Company’s stockholders with respect to the voting or transfer of the
Company’s capital stock or with respect to any other aspect of the Company’s affairs.

the Company. This Warrant constitutes a valid and binding obligation of the Company, enforceable
in accordance with its terms. The execution and delivery by the Company of this Warrant, the

Arrangement, Company shall deliver to Warrantholder such financial information as is required under
the terms of the Financing Arrangement. From and after the date that the Company shall have

Warrantholder (so long as the Warrantholder holds all or any portion of the Warrant or any
Preferred Stock or any shares of Common Stock issuable upon conversion of the Preferred Stock) all
