the resale of all Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415, on Form S-1 (or
on such other form appropriate for such purpose). Such Registration Statement shall contain (except if otherwise required pursuant

attached hereto as Annex A with such changes as may be made in response to SEC comments. The Company shall use reasonable
best efforts to cause such Registration Statement to be declared effective under the Securities Act no later than its Effectiveness
Date, and shall use its reasonable best efforts to keep each such Registration Statement continuously effective during the entire
Effectiveness Period. By 5:30 p.m. (New York City time) on the Business Day immediately following the Effective Date of such Registration
Statement, the Company shall file with the Commission in accordance with Rule 424 under the Securities Act the final prospectus
to be used in connection with sales pursuant to such Registration Statement (whether or not such filing is technically required

    	-3-

    	 

    

 

(b)          Notwithstanding
anything to the contrary contained in this Section 2, if the Company receives Commission Comments, and following discussions with
and responses to the Commission in which the Company uses its reasonable best efforts and time to cause as many Registrable Securities
as possible to be included in the Registration Statement filed pursuant to Section 2(a) without characterizing any Holder as an
underwriter unless such characterization is consistent with written information provided by the Holder in the Selling Holder Questionnaire
(as defined below) (the day that such discussions and responses are concluded shall be referred to as the “Tolling Date”),
the Company is unable to cause the inclusion of all Registrable Securities, then the Company may, following not less than three
(3) Trading Days prior written notice to the Holders (i) remove from the Registration Statement such Registrable Securities (the
“Cut Back Shares”) and/or (ii) agree to such restrictions and limitations on the registration and resale of
the Registrable Securities, in each case as the Commission may require in order for the Commission to allow such Registration Statement
to become effective; provided, that in no event may the Company characterize any Holder as an underwriter unless such characterization
is consistent with written information provided by the Holder in the Selling Holder Questionnaire or such Holder agrees to such
characterization (collectively, the “SEC Restrictions”). Unless the SEC Restrictions otherwise require, any
cut-back imposed pursuant to this Section 2(b) shall be allocated among the Shares of the Holders on a pro rata basis. Notwithstanding
the foregoing, the Company shall be permitted to exclude all Registrable Securities of a Holder if the Commission has advised the
Company that such Holder must be characterized as an underwriter and the Holder does not agree to such characterization. The required
Effectiveness Date for any Registration Statement intended to register Cut Back Shares will be tolled until such time as the Company
is able to effect the registration of the Cut Back Shares in accordance with any SEC Restrictions if such Registrable Securities
cannot at such time be resold by the Holders thereof pursuant to Rule 144 (such date, the “Restriction Termination Date”).
From and after the Restriction Termination Date, all provisions of this Section 2 shall again be applicable to the Cut Back Shares
(which, for avoidance of doubt, retain their character as “Registrable Securities”) if such Registrable Securities
cannot at such time be resold by the Holders thereof pursuant to Rule 144 so that the Company will be required to use its reasonable
best efforts to file with and cause to be declared effective by the Commission such additional Registration Statements to ultimately
cause to be covered by effective Registration Statements all Registrable Securities.

 

(c)          The
Company shall promptly notify the Holders via facsimile or by e-mail delivery of a “.pdf” format data file of the effectiveness
of a Registration Statement on or prior to the Trading Day following the date that the Company telephonically confirms effectiveness
with the Commission, which shall be the date requested for effectiveness of a Registration Statement.

 

    	-4-

    	 

    

 

(d)          If:
(i) a Registration Statement required to be filed pursuant to Section 2(a) is not filed on or prior to its Filing Date, or (ii)
a Registration Statement registering for resale all of the Registrable Securities is not declared effective by the Commission by
the Effectiveness Date of the Registration Statement, or (iii) after the Effectiveness Date of a Registration Statement, such Registration
Statement ceases for any reason to remain continuously effective as to all Registrable Securities included in such Registration
Statement, or the Holders are otherwise not permitted to utilize the Prospectus therein to resell such Registrable Securities,
for more than 30 consecutive calendar days or more than an aggregate of 60 calendar days during any 12-month period (which need
not be consecutive calendar days) (any such failure or breach being referred to as an “Event”, and for purposes
of clause (i) or (ii) the date on which such Event occurs, or for purposes of (iii) the date on which such 30 or 60 calendar day
period, as applicable, is exceeded, being referred to as “Event Date”), then, in addition to any other rights
the Holders may have hereunder or under applicable law, on each monthly anniversary of each such Event Date (if the applicable
Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount
in cash, as partial liquidated damages and not as a penalty, equal to 0.5% of the aggregate purchase price paid by such Holder
pursuant to the Purchase Agreement for any unregistered Registrable Securities then held by such Holder; provided, however, that
the maximum aggregate amount of liquidated damages payable under this Section 2(d) shall be 6%.

 

(e)          Each
Holder agrees to furnish to the Company a completed Questionnaire in the form attached to this Agreement as Annex B (a “Selling
Holder Questionnaire”). The Company shall not be required to include the Registrable Securities of (or pay liquidated
damages to) a Holder in a Registration Statement who fails to furnish to the Company a fully completed Selling Holder Questionnaire
at least three (3) Trading Days prior to the Filing Date (subject to the requirements set forth in Section 3(a)).

 

3.            Registration
Procedures.

 

In connection with the Company's
registration obligations hereunder, the Company shall:

 

(a)          Not
less than three (3) Trading Days prior to the filing of each Registration Statement or any related Prospectus or any amendment
or supplement thereto, the Company shall (i) furnish to each Holder copies of all such documents proposed to be filed, which documents
shall be subject to the review of such Holders and (ii) cause its officers, directors, counsel and independent certified public
accountants to respond to such inquiries as shall be reasonably necessary to conduct a reasonable review of such documents. The
Company shall not file a Registration Statement, any Prospectus or any amendments or supplements thereto in which the “Selling
Stockholder” section thereof differs from the disclosure received from a Holder in its Selling Holder Questionnaire (as amended
or supplemented) except in response to SEC comments or to which the Holders of a majority of the Registrable Securities included
in such Registration Statement object not less than two Trading Days after all Holders have been furnished all of the documents
proposed to be filed.

 

    	-5-

    	 

    

(b)          Use
its reasonable best efforts to: (i) Prepare and file with the Commission such amendments, including post-effective amendments,
to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement
continuously effective as to the applicable Registrable Securities for its Effectiveness Period and prepare and file with the Commission
such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement, and as so supplemented or
amended to be filed pursuant to Rule 424; (iii) respond promptly to any comments received from the Commission with respect to each
Registration Statement or any amendment thereto and, promptly provide the Holders true and complete copies of all correspondence
from and to the Commission relating to such Registration Statement that would not result in the disclosure to the Holders of material
and non-public information concerning the Company; and (iv) comply in all material respects with the provisions of the Securities
Act and the Exchange Act with respect to the Registration Statements and the disposition of all Registrable Securities covered
by each Registration Statement.

 

(c)          Notify
the Holders (which notice shall, if pursuant to clauses (iii) through (v) hereof, be accompanied by an instruction to suspend use
of the Prospectus until the required changes have been made) as promptly as reasonably possible (and, in the case of (i)(A) below,
not less than three (3) Trading Days prior to such filing, in the case of (iii) below, on or prior to the Trading Day following
receipt by the Company of such notice by the Commission, and in the case of (v) below, not less than three (3) Trading Days prior
to the financial statements in any Registration Statement becoming ineligible for inclusion therein or (y) on such other date upon
which such event has occurred) and (if requested by any such Person) confirm such notice in writing no later than one (1) Trading
Day following the day (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement
is proposed to be filed; and (B) when the Commission notifies the Company whether there will be a "review" of such Registration
Statement and whenever the Commission comments in writing on such Registration Statement (the Company shall provide true and complete
copies thereof and all written responses thereto to each of the Holders that pertain to the Holders as a Selling Stockholder or
to the Plan of Distribution, but not information which the Company believes would constitute material and non-public information);
(ii) of any request by the Commission or any other Federal or state governmental authority for amendments or supplements to a Registration
Statement or Prospectus or for additional information; (iii) of the issuance by the Commission or any other federal or state governmental
authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities
or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction,
or the initiation or threatening of any Proceeding for such purpose; and (v) of the occurrence of any event or passage of time
that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made
in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue
in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in
the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

 

    	-6-

    	 

    

 

(d)          Use
commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order stopping or suspending
the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of
any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

 

(e)          Furnish
to each Holder, without charge, at least one (1) conformed copy of each Registration Statement and each amendment thereto and all
exhibits to the extent requested by such Person (including those previously furnished) promptly after the filing of such documents
with the Commission, to the extent that such documents are not available on EDGAR.

 

(f)          Subject
to Section 3(c) above, promptly deliver to each Holder, without charge, as many copies of each Prospectus or Prospectuses (including
each form of prospectus) and each amendment or supplement thereto as such Persons may reasonably request to the extent that such
documents are not available on EDGAR. Subject to Section 6(b) herein, the Company hereby consents to the use of such Prospectus
and each amendment or supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable
Securities covered by such Prospectus and any amendment or supplement thereto.

 

(g)          Prior
to any public offering of Registrable Securities, register or qualify such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as any Holder may request, to keep each such registration
or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the Registration
Statements; provided, however, in connection with any such registration or qualification, the Company shall not be required to
(i) qualify to do business in any jurisdiction where the Company would not otherwise be required to qualify, (ii) subject itself
to general taxation in any such jurisdiction, (iii) file a general consent to service of process in any jurisdiction, or (iv) make
any change to the Company’s Articles of Incorporation or bylaws.

 

(h)          Cooperate
with the Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered
to a transferee pursuant to the Registration Statements, and to enable such Registrable Securities to be in such denominations
and registered in such names as any such Holders may request.

 

(i)          Upon
the occurrence of any event contemplated by Section 3(c)(v) and during the Effectiveness Period, as promptly as reasonably possible
under the circumstances taking into account the Company’s good faith assessment of any adverse consequences to the Company
and its security holders of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective
amendment, to the affected Registration Statements or a supplement to the related Prospectus or any document incorporated or deemed
to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration
Statement nor any Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

 

    	-7-

    	 

    

 

(j)          Comply
with all applicable rules and regulations of the Commission.

 

4.          Registration

by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred
to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with any Trading Market on which the Common Stock is then listed
for trading, and (B) in compliance with applicable state securities or Blue Sky laws), (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities and of printing prospectuses if the printing of prospectuses

5.          Indemnification.

 

(a)          Indemnification
by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder,
the officers, directors, members, managers and employees (and any other Persons with a functionally equivalent role of a Person
holding such titles, notwithstanding a lack of such title or any other title) of each of them, each Person who controls any such
Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors,
members, managers, shareholders and employees (and any other Persons with a functionally equivalent role of a Person holding such
titles, notwithstanding a lack of such title or any other title) of each such controlling Person, to the fullest extent permitted
by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable
costs of preparation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred,
arising out of or relating to any untrue statement of a material fact contained in a Registration Statement, any Prospectus or
any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating
to any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of Prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading,
except to the extent that (i) such untrue statements or omissions are based upon information regarding such Holder furnished in
writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder
or such Holder’s proposed method of distribution of Registrable (it being understood that the Holder has approved Annex
A hereto for this purpose) or (ii) in the case of an occurrence of an event of the type specified in Section 3(c)(iii)-(v),
the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing that the Prospectus
is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(b). The Company shall
notify the Holders promptly of the institution, threat or assertion of any Proceeding arising from or in connection with the transactions
contemplated by this Agreement of which the Company is aware.

 

    	-8-

    	 

    

 

(b)          Indemnification
by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted
by applicable law, from and against all Losses, as incurred, to the extent arising out of or based upon: (x) such Holder’s
failure to comply with the prospectus delivery requirements of the Securities Act, (y) any untrue statement of a material fact
contained in any Registration Statement, any Prospectus, or in any amendment or supplement thereto or in any preliminary prospectus,
or arising out of or relating to any omission of a material fact required to be stated therein or necessary to make the statements
therein not misleading (i) to the extent that such untrue statement or omission is contained in any information so furnished in
writing by such Holder to the Company specifically for inclusion in such Registration Statement or such Prospectus or (ii) such
information relates to such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved
by such Holder for use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for
this purpose), such Prospectus or such form of Prospectus in any amendment or supplement thereto or (z) in the case of an occurrence
of an event of the type specified in Section 3(c)(iii)-(v), the use by such Holder of an outdated or defective Prospectus after
the Company has notified such Holder in writing that the Prospectus is outdated or defective and prior to the receipt by such Holder
of the Advice contemplated in Section 6(b).

 

(c)          Conduct
of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party shall promptly notify the Person from whom indemnity is sought
(the "Indemnifying Party") in writing, and the Indemnifying Party shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses incurred in
connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall
be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that
such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

 

    	-9-

    	 

    

 

An Indemnified Party shall
have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing
to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and
to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding (it being agreed that Blank Rome LLP
shall be deemed satisfactory to the Holders); or (3) the named parties to any such Proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that
a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party
(in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel
at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and the
reasonable fees and expense of one (1) such counsel for the Indemnified Parties shall be at the expense of the Indemnifying Party).
The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld or delayed. No Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement
includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

 

(d)          Contribution.
If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise) or insufficient to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute
to the amount paid or payable by such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses
as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall
be determined by reference to, among other things, whether any action in question, including any untrue statement of a material
fact or omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party
or Indemnified Party, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent
such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include,
subject to the limitations set forth in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses incurred by
such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if
the indemnification provided for in this Section was available to such party in accordance with its terms.

 

The parties hereto agree
that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or
by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding
paragraph.

 

The indemnity and contribution
agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have to the Indemnified
Parties.

Disposition. Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice from the Company
of the occurrence of any event of the kind described in Section 3(c)(iii) through (v), such Holder will forthwith discontinue disposition
of such Registrable Securities under the Registration Statement until such Holder's receipt of the copies of the supplemented Prospectus
and/or amended Registration Statement or until it is advised in writing (the "Advice") by the Company that the
use of the applicable Prospectus may be resumed. The Company will use its reasonable best efforts to ensure that the use of the
Prospectus may be resumed as promptly as it practicable. The Company agrees and acknowledges that any periods during which the
Holder is required to discontinue the disposition of the Registrable Securities hereunder shall be subject to the provisions of
Section 2(g).

writing and signed by the Company and the Holders of no less than a majority in interest of the then outstanding Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively
to the rights of certain Holders (including to exclude or remove a certain Holder’s Registrable Securities from a Registration
Statement) and that does not directly or indirectly affect the rights of other Holders may be given by Holders of at least a majority
of the Registrable Securities to which such waiver or consent relates.

Annex A

 

PLAN OF DISTRIBUTION

 

We are registering the shares
of common stock that may be received upon conversion of promissory notes previously issued and the shares of common stock that
may be received upon exercise of common stock purchase warrants previously issued, to permit the resale of these shares of common
stock by the holders of the common stock from time to time after the date of this prospectus. We will bear all fees and expenses
incident to our obligation to register the shares of common stock.

 

The selling security holders
may sell all or a portion of the shares of common stock beneficially owned by them and offered hereby from time to time directly
or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers,
the selling security holders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares
of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at
varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may
involve crosses or block transactions,

 

·     on
any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

 

·     in
the over-the-counter market;

 

·     in
transactions otherwise than on these exchanges or systems or in the over-the-counter market;

 

·     through
the writing of options, whether such options are listed on an options exchange or otherwise;

 

·     ordinary
brokerage transactions and transactions in which the broker-dealer solicits purchasers;

 

·     block
trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as
principal to facilitate the transaction;

 

·     purchases
by a broker-dealer as principal and resale by the broker-dealer for its account;

 

·     an
exchange distribution in accordance with the rules of the applicable exchange;

 

·     privately
negotiated transactions;

 

·     sales
pursuant to Rule 144;

 

·     broker-dealers
may agree with the selling security holders to sell a specified number of such shares at a stipulated price per share;

 

·     a
combination of any such methods of sale; and

 

    	A-1

    	 

    

 

·     any
other method permitted pursuant to applicable law.

 

If the selling security
holders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters,
broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling security
holders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as
principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess
of those customary in the types of transactions involved). In connection with sales of the shares of common stock or otherwise,
the selling security holders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of
the shares of common stock in the course of hedging in positions they assume. The selling security holders may also loan or pledge
shares of common stock to broker-dealers that in turn may sell such shares.

 

The selling security holders
may pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the
performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time
to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the
Securities Act, amending, if necessary, the list of selling security holders to include the pledgee, transferee or other successors
in interest as selling security holders under this prospectus. The selling security holders also may transfer and donate the shares
of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be
the selling beneficial owners for purposes of this prospectus.

 

The selling security holders
and any broker-dealer participating in the distribution of the shares of common stock may be deemed to be “underwriters”
within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer
may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares
of common stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of
shares of common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents,
any discounts, commissions and other terms constituting compensation from the selling security holders and any discounts, commissions
or concessions allowed or reallowed or paid to broker-dealers.

 

Under the securities laws
of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In
addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale
in such state or an exemption from registration or qualification is available and is complied with.

 

There can be no assurance
that any selling stockholder will sell any or all of the shares of common stock registered pursuant to the registration statement,
of which this prospectus forms a part.

 

    	A-2

    	 

    

 

The selling security holders
and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules
and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases
and sales of any of the shares of common stock by the selling security holders and any other participating person. Regulation M
may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making
activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common
stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.

 

We will pay all expenses
of the registration of the shares of common stock pursuant to the registration rights agreement, estimated to be $[ ] in total,
including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities
or “blue sky” laws; provided, however, that a selling stockholder will pay all underwriting discounts and selling commissions,
if any. We will indemnify the selling security holders against liabilities, including some liabilities under the Securities Act,
in accordance with the registration rights agreements, or the selling security holders will be entitled to contribution. We may
be indemnified by the selling security holders against civil liabilities, including liabilities under the Securities Act, that
may arise from any written information furnished to us by the selling security holders specifically for use in this prospectus,
in accordance with the related registration rights agreements, or we may be entitled to contribution.

AMERICAN STANDARD ENERGY CORP.

INVESTOR QUESTIONNAIRE

 

NAME OF INVESTOR:
_________________________________

 

In connection with your purchase of certain
securities (the “Securities”) of American Standard Energy Corp. (the "Company")
pursuant to the Note and Warrant Purchase Agreement dated as of February__, 2012 (as amended, amended and restated, supplemented
or otherwise modified from time to time, the “Purchase Agreement”), by and among the Company, ASEN 2,
Corp., a Delaware corporation and the investors, please provide the Company with the following information for the Company’s
use in preparing a Registration Statement (the “Registration Statement”) relating to the Securities acquired
by you which you are asking the Company to register. You should complete this questionnaire as if the Purchase Agreement has
already been consummated. Therefore, please provide the requisite share ownership amounts and other information that will be correct
as of the time of the filing of the Registration Statement. 

 

A.          General
Information

 

1.          Please
state your or your organization’s name exactly as it should appear on the Registration Statement.

 

2.          Please
provide the Tax Identification Number of the person or entity listed in response to Item 1 above.

 

3.          Have
you or your organization had any position, office or other material relationship within the past three years with the Company or
any of its affiliates (other than as a participant in the Offerings)?

 

 ̈
Yes          No  ̈

 

If yes, please indicate the nature of any such relationships below:

 

4.          Does
the Plan of Distribution attached to this Questionnaire as Schedule A accurately reflect the means by which you ultimately
intend to dispose or sell the Securities?

 

 ̈
Yes           ̈ No

 

    	B-1

    	 

    

 

B.           Securities
Holdings

 

Please fill in all blanks in the following
questions related to your beneficial ownership of the Company’s capital stock. Generally, the term “beneficial
ownership” refers to any direct or indirect interest in the securities which entitles you to any of the rights or
benefits of ownership, even though you may not be the holder of record of the securities. For example, securities held in “street
name” over which you exercise voting or investment power would be considered beneficially owned by you. Other
examples of indirect ownership include ownership by a partnership in which you are a partner or by an estate or trust of which
you or any member of your immediate family is a beneficiary. Ownership of securities held in the names of your spouse,
minor children or other relatives who live in the same household may be attributed to you.

 

Please note:  If
you have any reason to believe that any interest in securities of the Company which you may have, however remote, is a beneficial
interest, please describe such interest. For purposes of responding to this questionnaire, it is preferable to err on the side
of inclusion rather than exclusion. Where the SEC's interpretation of beneficial ownership would require disclosure
of your interest or possible interest in certain securities of the Company, and you believe that you do not actually possess the
attributes of beneficial ownership, an appropriate response is to disclose the interest and at the same time disclaim beneficial
ownership of the securities.

 

1.          As
of the closing of the Private Purchase Agreement, I owned outright (including shares registered in my name individually or jointly
with others, shares held in the name of a bank, broker, nominee, depository or in “street name” for my account), the
following number of shares of the Company’s capital stock:

 

2.          As
of the closing of the Purchase Agreement, I owned the following number of securities that are exercisable or exchangeable for,
or convertible into the Company’s common stock:

 

3.          In
addition to the number of shares I own outright as indicated by my answer to Item B(l), as of the closing of the Purchase Agreement,
I had or shared voting power or investment power, directly or indirectly, through a contract, arrangement, understanding, relationship
or otherwise, over the following number of shares of the Company's capital stock:

 

4.          Please
identify the natural person or persons who have voting and/or investment control over the Company's securities that you own, and
state whether such person(s) disclaims beneficial ownership of the securities. For example, if you are a general partnership, please
identify the general partners in the partnership.

 

    	B-2

1.            Modification

any of such Securities in violation of the Securities Act or any applicable state securities law and has no direct or indirect

hereunder in the ordinary course of its business.

 

6.2           Opportunities

6.3           Holder
Status.  At the time Holder was offered the Securities, it was, and as of the date hereof it is, and on each date
on which it converts any Series C Warrants it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1),
(a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act; or (ii) a “qualified institutional buyer” as defined in

in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities,
and has so evaluated the merits and risks of such investment.   Holder is able to bear the economic risk of an investment
in the Securities and, at the present time, is able to afford a complete loss of such investment. 

  

6.5           General
Solicitation.   Holder is not obtaining the Securities as a result of any advertisement, article, notice or other

Act or an exemption from registration is available. Holder acknowledges that Holder is familiar with Rule 144 of the rules and
regulations of the Securities and Exchange Commission, as amended, promulgated pursuant to the Securities Act (“Rule 144”),
and that Holder has been advised that Rule 144 permits resales only under certain circumstances. Holder understands that to the

Act or the existence of another exemption from such registration requirement.
