against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director,

The number of shares of common stock, par value $0.00001 per share ("Common Stock"), of Aspen Aerogels, Inc. (the "Registrant"), stated above consists of the aggregate number of shares which may be
sold (i) upon the exercise of options which have been granted under the Aspen Aerogels, Inc. 2001 Equity Incentive Plan, as amended (the "2001 Plan"), and (ii) upon the exercise of options or issuance of stock-based awards which
may hereafter be granted under the Aspen Aerogels, Inc. 2014 Employee, Director and Consultant Equity Incentive Plan (the "2014 Plan," and together with the 2001 Plan, the "Plans"). The maximum number of shares which may be sold
upon the exercise of such options or issuance of stock-based awards granted under the Plans are subject to adjustment in accordance with certain anti-dilution and other provisions of the Plans. Accordingly, pursuant to Rule 416 under the Securities
Act of 1933, as amended (the "Securities Act"), this Registration Statement covers, in addition to the number of shares stated above, an indeterminate number of shares which may be subject to grant or otherwise issuable after the operation
of any such anti-dilution and other provisions.

average of the high and the low price of Registrant's Common Stock as reported on the New York Stock Exchange as of a date (August 7, 2014) within five business days prior to filing this Registration Statement. The chart below details the

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
Item 3. Incorporation of Documents by Reference.
The following documents filed by the Registrant with the Commission are incorporated herein by reference:
(a) The prospectus filed by the Registrant with the Commission pursuant to Rule 424(b)(4) under the Securities Act, on June 16, 2014,
relating to the registration statement on Form S-1 originally filed on April 28, 2014, as amended (File
No. 333-195523),
which contains the Registrant's audited financial statements for the
latest fiscal year for which such statements have been filed.
(b) The Registrant's Quarterly Report on Form 10-Q for the fiscal
quarter ended June 30, 2014, filed on August 8, 2014;
(c) The Registrant's Current Report on Form 8-K filed on
June 19, 2014; and
(d) The description of the Registrant's common stock contained in the Registrant's Registration
Statement on Form 8-A (File No. 001-36481) filed on June 6, 2014, including any amendments or reports filed for the purpose of updating such description.
All reports and other documents filed by the Registrant after the date hereof pursuant to Sections 13(a), 13(c), 14 and 15(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), prior to the filing of a post-effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining
unsold, shall be deemed to be incorporated by reference herein and to be part hereof from the date of filing of such reports and documents. Any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for the purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein
modifies or supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of
Named Experts and Counsel.
None.
Item 6. Indemnification of Directors and Officers.
The Registrant's restated certificate of incorporation and restated by-laws provide that each person who was or is made a party or is
threatened to be made a party to or is otherwise involved (including, without limitation, as a witness) in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was one
of the Registrant's directors or officers or is or was serving at the Registrant's request as a director, officer or trustee of another corporation, or of a partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan, whether the basis of such proceeding is alleged action in an official capacity as a director, officer or trustee or in any other capacity while serving as a director, officer or trustee, shall be indemnified and
held harmless by the Registrant to the fullest extent authorized by the Delaware General Corporation Law against all expense, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in
settlement) reasonably incurred or suffered by such.
3
Section 145 of the Delaware General Corporation Law permits a corporation to indemnify any
director or officer of the corporation against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with any action, suit or proceeding brought by reason of the
fact that such person is or was a director or officer of the corporation, if such person acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to
any criminal action or proceeding, if he or she had no reasonable cause to believe his or her conduct was unlawful. In a derivative action (i.e., one brought by or on behalf of the corporation), indemnification may be provided only for expenses
actually and reasonably incurred by any director or officer in connection with the defense or settlement of such an action or suit if such person acted in good faith and in a manner that he or she reasonably believed to be in, or not opposed to, the
best interests of the corporation, except that no indemnification shall be provided if such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the Delaware Chancery Court or the court in which the
action or suit was brought shall determine that such person is fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability.
Pursuant to Section 102(b)(7) of the Delaware General Corporation Law, Article NINTH of the Registrant's restated certificate of
incorporation eliminates the liability of a director to the Registrant or its stockholders for monetary damages for such a breach of fiduciary duty as a director, except for liabilities arising:
•
from any breach of the director's duty of loyalty to the Registrant or its stockholders;
•
from acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;
•
under Section 174 of the Delaware General Corporation Law; and
•
for any transaction from which the director derived an improper personal benefit.
The
Registrant has entered into indemnification agreements with its non-employee directors and will enter into similar agreements with certain officers, in addition to the indemnification provided for in the Registrant's restated certificate of
incorporation and restated by-laws, and intends to enter into indemnification agreements with any new directors and executive officers in the future. The Registrant has purchased and intends to maintain insurance on behalf of any person who is or
was a director or officer against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.
The foregoing discussion of the Registrant's restated certificate of incorporation, restated by-laws, indemnification agreements and
Delaware law is not intended to be exhaustive and is qualified in its entirety by such restated certificate of incorporation, restated by-laws, indemnification agreements or law.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
The Index to Exhibits immediately preceding the exhibits is incorporated herein by reference.
Item 9. Undertakings.
(a) The undersigned
Registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
4
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price
represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement.
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
Provided, however
, that Paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form
S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
(2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating
to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the indemnification provisions summarized in Item 6, or otherwise,
the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
