          (A) first, all the Registrable Shares that are issued or issuable upon conversion of the Series B Preferred Stock and any True-Up Shares (collectively, “Series B Registrable Shares”), subject to the last sentence of Section 2(a), requested to be included in such registration (or, if necessary, such Series B Registrable Shares pro rata among the Holders thereof based upon the number of Series B Registrable Shares requested to be registered by each such Holder);

          (i) first, the Primary Shares;
          (ii) second, the Series B Registrable Shares (or, if necessary, such Series B Registrable Shares will be cutback pro rata among the holders thereof based upon the number of Series B Registrable Shares requested to be registered by each such holder (or Series B Registrable Shares issued in respect thereof));

provided, however, that no Registrable Shares or Other Shares shall be required to be included in any registration pursuant to this Section 3 in connection with the Company’s initial public offering if the Company and the underwriters determine, in their sole discretion, not to include any shares other than Primary Shares.
     Section 4. Registrations on Form S-3.
          Anything contained in Section 2 to the contrary notwithstanding, at such time as the Company shall have qualified for the use of Form S-3 promulgated under the Securities Act or any successor form thereto, holders of the Registrable Shares then outstanding shall have the right to request in writing an unlimited number of registrations of Registrable Shares on Form S-3 or such successor form, which request or requests shall (i) specify the number of Registrable Shares intended to be sold or disposed of and the holders thereof, (ii) state the intended method of disposition of such Registrable Shares and (iii) relate to Registrable Shares having an aggregate offering price of at least $2,000,000. A requested registration on Form S-3 or any such successor form in compliance with this Section 4 shall not count as a registration statement initiated pursuant to Section 2, but shall otherwise be treated as a registration initiated pursuant to, and shall, except as otherwise expressly provided in this Section 4, be subject to Section 2; provided, however, that the Company shall not be obligated to (a) effect more than two registrations pursuant to this Section 3 in any twelve (12) month period or (b) keep effective at any one time more than one registration statement on Form S-3 with respect to Registrable Shares requested to be registered in accordance with this Section 4, and if the Company is requested to effect the registration of Registrable Shares on Form S-3 at a time when it is keeping such a registration statement effective, it may delay effecting such requested registration until it is no longer required in accordance with Section 6(a) hereof to keep effective the then effective registration statement on Form S-3.

          (b) In connection with any registration of Registrable Shares under the Securities Act pursuant to this Agreement, each holder of Registrable Shares shall severally, and not jointly, indemnify and hold harmless (in the same manner and to the same extent as set forth in the preceding paragraph of this Section 8) the Company, each director of the Company, each officer of the Company who shall sign such registration statement, each underwriter, broker or other person acting on behalf of the holders of Registrable Shares and each person who controls any of the foregoing persons within the meaning of the Securities Act with respect to any statement or omission from such registration statement, any preliminary prospectus or final prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares, if such statement or omission was made in reliance upon and in conformity with written information furnished to the Company or such underwriter by such holder of Registrable Shares specifically for use in connection with the preparation of such registration statement, preliminary prospectus, final prospectus, amendment, supplement or document; provided, however, that the maximum amount of liability in respect of such indemnification shall be limited, in the case of each seller of Registrable Shares, to an amount equal to the net proceeds actually received by such Seller from the sale of Registrable Shares effected pursuant to such registration.
          (c) Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to in the preceding paragraphs of this Section 8, such indemnified party will, if a claim in respect thereof is made against an indemnifying party, give written notice to the latter of the commencement of such action. The failure of any indemnified party to notify an indemnifying party of any such action shall not

-12-


 

(unless such failure shall have a material adverse effect on the indemnifying party) relieve the indemnifying party from any liability in respect of such action that it may have to such indemnified party on account of this Section 8. In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that if any indemnified party shall have reasonably concluded that there may be one or more legal or equitable defenses available to such indemnified party which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity agreement provided in this Section 8, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party (but shall have the right to participate therein with counsel of its choice) and such indemnifying party shall reimburse such indemnified party and any person controlling such indemnified party for that portion of the fees and expenses of any counsel retained by the indemnified party which is reasonably related to the matters covered by the indemnity agreement provided in this Section 8. If the indemnifying party is not entitled to, or elects not to, assume the defense of a claim, it will not be obligated to pay the fees and expenses of more than one counsel with respect to such claim.
          (d) If the indemnification provided for in this Section 8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just and equitable if contribution pursuant hereto were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to herein. No person guilty of fraudulent misrepresentation shall be entitled to contribution from any person.
          (e) The obligations of the Company and Holders under this Section 8 shall survive completion of any offering of Registrable Shares in a registration statement and the termination of this Agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

     Section 9. Underwriting Agreement.
          Notwithstanding the provisions of Sections 5, 6, 7 and 8, to the extent that the Company and the Investors shall enter into an underwriting or similar agreement, which agreement contains provisions covering one or more issues addressed in such Sections, the provisions contained in such agreement addressing such issue or issues shall control. Each Holder further agrees to execute such customary lock-up agreements as may be reasonably requested by the underwriters in connection with an underwritten offering.
     Section 10. Information by Holders.

          With a view to making available to the Holders the benefits of certain rules and regulations of the Commission which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its best efforts to:
          (a) make and keep public information available, as those terms are understood and defined in Commission Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the IPO;
          (b) take such action, including the voluntary registration of its Common Stock under Section 12 of the Exchange Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the offering of its securities to the general public is declared effective;
          (c) file with the Commission, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and
          (d) furnish to such Holder forthwith upon request: (i) a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company), of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); (ii) a copy of the most recent annual or quarterly report of the Company and such other forms and reports filed by the Company with the Commission; and (iii) such other reports and documents as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing it to sell any such securities without registration.

ASPEN AEROGELS, INC.
AMENDMENT NO. 1 TO
FIFTH AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT
     This Amendment No. 1 to Fifth Amended and Restated Registration Rights Agreement (this “Amendment”) is entered into as of December 29, 2010, by and among Aspen Aerogels, Inc., a Delaware corporation (the “Company”) and the Investors set forth on the signature pages hereto, constituting the holders of at least a majority of the Registrable Shares currently outstanding which are issued or issuable upon conversion of the Preferred Stock (the “Requisite Holders”). Capitalized terms used herein but not defined shall have the meanings ascribed to them in the Fifth Amended and Restated Registration Rights Agreement of the Company, entered into as of September 22, 2010 (the “Original Agreement”).
     WHEREAS, the Company and the Requisite Holders wish to amend the Original Agreement, in accordance with Section 18 thereof.
     NOW, THEREFORE, for valid and adequate consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:
     1. The definition of “Registrable Shares” in Section 1 of the Original Agreement is deleted in its entirety and the following language is substituted in lieu thereof:
     “Registrable Shares” means (i) the Common Stock issuable or issued upon the voluntary conversion on August 14, 2009 of the Company’s formerly outstanding Series A-1, A-2, A-3, B-1, B-2 and B-3 Preferred Stock; (ii) the Common Stock issuable or issued upon conversion of the Preferred Stock, (iii) any True-Up Shares, (iv) any Warrant Stock and (v) any other shares of Common Stock issued as a dividend or other distribution with respect to, or in exchange for or replacement of, any of the shares of Common Stock referred to in clauses (i), (ii), (iii) or (iv). As to any particular Registrable Shares, once issued, such Registrable Shares shall cease to be Registrable Shares when (i) they have been registered under the Securities Act, the registration statement in connection therewith has been declared effective and they have been disposed of pursuant to such effective registration statement, or (ii) such Registrable Shares are held by an Investor (together with its affiliates) if (A) as reflected on the Company’s books and records, such Investor (together with its affiliates) holds less than 1% of the Company’s outstanding Common Stock (on an as-if-converted to Common Stock basis), (B) the Company has completed a QPO and (C) all shares of Common Stock issued or issuable upon conversion of such Registrable Shares held by and issuable to such Investor (and its affiliates) may be sold pursuant to Rule 144 during any ninety (90) day period.
     2. The Original Agreement shall be amended by adding two new definitions to Section 1 thereof as follows:
     “Warrants” means those certain warrants to initially subscribe for and purchase an aggregate of 1,496,107 shares of Common Stock issued by the Company to certain purchasers

 


 

pursuant to a Subordinated Note and Warrant Purchase Agreement dated as of December __, 2010 by and among the Company, Aspen Aerogels Rhode Island, LLC and the “Purchasers” named therein, together with any warrants issued upon the transfer or division of, or in exchange or substitution for any such Warrants.
     “Warrant Stock” means all shares of Common Stock which may be issued upon the exercise of the rights represented by the Warrants.
     3. The Original Agreement shall be amended by adding the initial holders of the Warrants as parties to the Original Agreement upon each such holder’s execution and delivery to the Company of a Joinder Agreement in the form attached hereto as Exhibit A. Thereafter such persons shall be deemed an “Investor” for all purposes under the Original Agreement, as amended hereby.
     4. This Amendment contains the entire agreement among the parties hereto with respect to the subject matter hereof.
     5. This Amendment may be executed in any number of counterparts, each of which shall be deemed to be an original instrument and all which together shall constitute one and the same agreement. This Amendment may be executed by facsimile or by electronic or PDF file.

ASPEN AEROGELS, INC.
AMENDMENT NO. 2 TO
FIFTH AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT
     This Amendment No. 2 to Fifth Amended and Restated Registration Rights Agreement (this “Amendment”) is entered into as of June 1, 2011, by and among Aspen Aerogels, Inc., a Delaware corporation (the “Company”), and the Investors set forth on the signature pages hereto, constituting the holders of at least a majority of the Registrable Shares currently outstanding which are issued or issuable upon conversion of the Preferred Stock (the “Requisite Holders”). Capitalized terms used herein but not defined shall have the meanings ascribed to them in the Fifth Amended and Restated Registration Rights Agreement of the Company, as amended by Amendment No. 1 dated December 29, 2010 (the “Original Agreement”).
     WHEREAS, the Company and the Requisite Holders wish to amend the Original Agreement in accordance with Section 18 thereof.
     NOW, THEREFORE, for valid and adequate consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:
     1. The definition of “Registrable Shares” in Section 1 of the Original Agreement is deleted in its entirety and the following language is substituted in lieu thereof:
     “Registrable Shares” means (i) the Common Stock issuable or issued upon the voluntary conversion on August 14, 2009 of the Company’s formerly outstanding Series A-1, A-2, A-3, B1, B-2 and B-3 Preferred Stock; (ii) the Common Stock issuable or issued upon conversion of the Preferred Stock, (iii) any True-Up Shares, (iv) any Note Shares, (v) any Warrant Stock, (vi) solely with respect to the rights granted in Sections 3 and 4, the 2005 Warrant Stock, and (vii) any other shares of Common Stock issued as a dividend or other distribution with respect to, or in exchange for or replacement of any of the shares of Common Stock referred to in clauses (i), (ii), (iii), (iv), (v) or (vi). As to any particular Registrable Shares, once issued, such Registrable Shares shall cease to be Registrable Shares when (i) they have been registered under the Securities Act, the registration statement in connection therewith has been declared effective and they have been disposed of pursuant to such effective registration statement, or (ii) such Registrable Shares are held by an Investor (together with its affiliates) if (A) as reflected on the Company’s books and records, such Investor (together with its affiliates) holds less than 1% of the Company’s outstanding Common Stock (on an as-if-converted to Common Stock basis), (B) the Company has completed a QPO and (C) all shares of Common Stock issued or issuable upon conversion of such Registrable Shares held by and issuable to such Investor (and its affiliates) may be sold without limitation pursuant to Rule 144 during any ninety (90) day period.
     2. The Original Agreement shall be amended by adding four new definitions to Section 1 thereof as follows:
     “2005 Warrants” means those warrants to purchase Common Stock listed on Annex A hereto.”

 


 

     “2005 Warrant Stock” means all shares of Common Stock which may be issued upon exercise of the rights represented by the 2005 Warrants.”
     “Notes” means those certain convertible promissory notes convertible into shares of Common Stock issued by the Company to certain purchasers pursuant that certain Note Purchase Agreement dated as of June 1, 2011 by and among the Company and the “Purchasers” named therein, together with any Notes issued upon the transfer or division of, or in exchange or substitution for any such Notes.
     “Note Shares” means all shares of Common Stock which may be issued upon conversion of the Notes pursuant to the terms thereof.
     3. Section 4 of the Original Agreement is amended by adding the following to the end thereof:
     “, except the Company shall not be permitted to so delay any then effective registration on Form S-3 that is a “shelf” registration or a Rule 415 continuous offering.”
     4. Section 8(a) of the Original Agreement is amended by adding “or otherwise” after the phrase “pursuant to this Agreement” in the first clause thereof.
     5. Section 18 of the Original Agreement is amended by adding the following proviso at the end thereof:
     “provided, further, that at any time when any Warrants or Warrant Stock are outstanding, no amendment or waiver of any term or provision of this Agreement that is disproportionately adverse to the holders of the Warrants or Warrant Stock, as compared to the holders of the Registrable Shares, may be made without the written consent of the holders of two-thirds of the then outstanding Warrants and Warrant Stock; provided, further, that at any time when any Notes or Note Shares are outstanding, no amendment or waiver of any term or provision of this Agreement that is disproportionately adverse to the holders of the Notes or Note Shares, as compared to the holders of the Registrable Shares, may be made without the written consent of the holders of two-thirds of the then outstanding Notes and Note Shares.”
     6. The language in Section 15 of the Original Agreement is amended and restated in its entirety as follows:
     “An Investor may assign its rights hereunder to an Affiliate of such Investor or to any other purchaser or transferee of (a) at least 333,333 (or, if less, all) of such Investor’s Registrable Shares (as adjusted for stock splits, dividends, recapitalizations and the like) or (b) at least $1,000,000 principal amount of the Notes; provided, however, that (i) such purchaser or transferee may not be a competitor of the Company; (ii) such purchaser or transferee shall, as a condition to the effectiveness of such assignment, be required to execute a counterpart to this Agreement agreeing to be treated as an “Investor” hereunder; (iii) such purchaser or transferee shall be subject to the restrictions contained in this Agreement as if such purchaser or transferee was originally included in the definition of Investors herein and had originally been a party hereto; and (iv) such assignment must be made in compliance with Article II of the Settlement Agreement and First Amendment to Cross License Agreement

 


 

dated as of September 21, 2007 by and between Cabot Corporation and the Company.”
     7. The Original Agreement shall be amended by adding a new Annex A thereto in the form attached hereto as Annex A.
     8. The Original Agreement shall be amended by adding, to the extent such holder is not already a party to the Original Agreement, the initial holders of the Notes and the 2005 Warrants as parties to the Original Agreement upon each such holder’s execution and delivery to the Company of a Joinder Agreement in the form attached hereto as Exhibit A. Thereafter such persons shall be deemed an “Investor” for all purposes under the Original Agreement, as amended hereby.
     9. This Amendment contains the entire agreement among the parties hereto with respect to the subject matter hereof.
     10. This Amendment may be executed in any number of counterparts, each of which shall be deemed to be an original instrument and all which together shall constitute one and the same agreement. This Amendment may be executed by facsimile or by electronic or PDF file.
