EXHIBIT A-1


 


INVESTMENT REPRESENTATION STATEMENT 


 


	INVESTOR:	_____________________________________________
	COMPANY:	Q Holdings, Inc
	SECURITIES:	THE WARRANT ISSUED ON AUGUST 30, 2011, AS AMENDED (THE “WARRANT”) AND THE SECURITIES ISSUED OR ISSUABLE UPON EXERCISE THEREOF (INCLUDING UPON SUBSEQUENT CONVERSION OF THOSE SECURITIES)
	DATE:	____________________________


 


In connection with the
purchase or acquisition of the above-listed Securities, the undersigned Investor represents and warrants to, and agrees with, the
Company as follows:


 


1.No Registration.
The Investor understands that the Securities have not been, and will not be, registered under the Securities Act of 1933, as amended
(the “Securities Act”), by reason of a specific exemption from the registration provisions of the Securities
Act, the availability of which depends upon, among other things, the bona fide nature of the investment intent and the accuracy
of the Investor’s representations as expressed herein or otherwise made pursuant hereto.


 


2.Investment Intent.
The Investor is acquiring the Securities for investment for its own account, not as a nominee or agent, and not with a view to,
or for resale in connection with, any distribution thereof. The Investor has no present intention of selling, granting any participation
in, or otherwise distributing the Securities, nor does it have any contract, undertaking, agreement or arrangement for the same.


 


3.Investment Experience.
The Investor has substantial experience in evaluating and investing in private placement transactions of securities in companies
similar to the Company, and has such knowledge and experience in financial or business matters so that it is capable of evaluating
the merits and risks of its investment in the Company and protecting its own interests.


 


4.Speculative Nature
of Investment. The Investor understands and acknowledges that the Company has a limited financial and operating history and
that its investment in the Company is highly speculative and involves substantial risks. The Investor can bear the economic risk
of its investment and is able, without impairing its financial condition, to hold the Securities for an indefinite period of time
and to suffer a complete loss of its investment.


 


5.Access to Data.
The Investor has had an opportunity to ask questions of officers of the Company, which questions were answered to its satisfaction.
The Investor believes that it has received all the information that it considers necessary or appropriate for deciding whether
to acquire the Securities. The Investor understands that any such discussions, as well as any information issued by the Company,
were intended to describe certain aspects of the Company’s business and prospects, but were not necessarily a thorough or
exhaustive description. The Investor acknowledges that any business plans prepared by the Company have been, and continue to be,
subject to change and that any projections included in such business plans or otherwise are necessarily speculative in nature,
and it can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly
from actual results.


 



    	 



    	 



    

 


6.Accredited Investor.
The Investor is an “accredited investor” within the meaning of Regulation D, Rule 501(a), promulgated by
the Securities and Exchange Commission and agrees to submit to the Company such further assurances of such status as may be reasonably
requested by the Company.


 


7.Residency.
The residency of the Investor (or, in the case of a partnership or corporation, such entity’s principal place of business)
is correctly set forth on the signature page hereto.


 


8.Restrictions on
Resales. The Investor acknowledges that the Securities must be held indefinitely unless subsequently registered under the Securities
Act or an exemption from such registration is available. The Investor is aware of the provisions of Rule 144 promulgated under
the Securities Act, which permit resale of shares purchased in a private placement subject to the satisfaction of certain conditions,
which may include, among other things, the availability of certain current public information about the Company; the resale occurring
not less than a specified period after a party has purchased and paid for the security to be sold; the number of shares being sold
during any three-month period not exceeding specified limitations; the sale being effected through a “broker’s transaction,”
a transaction directly with a “market maker” or a “riskless principal transaction” (as those terms are
defined in the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder);
and the filing of a Form 144 notice, if applicable. The Investor acknowledges and understands that the Company may not be satisfying
the current public information requirement of Rule 144 at the time the Investor wishes to sell the Securities and that, in such
event, the Investor may be precluded from selling the Securities under Rule 144 even if the other applicable requirements
of Rule 144 have been satisfied. The Investor understands and acknowledges that, in the event the applicable requirements of Rule
144 are not met, registration under the Securities Act or an exemption from registration will be required for any disposition of
the Securities. The Investor understands that, although Rule 144 is not exclusive, the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell restricted securities received in a private offering other than in a registered
offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration
is available for those offers or sales and that those persons and the brokers who participate in the transactions do so at their
own risk.


 


9.No Public Market.
The Investor understands and acknowledges that no public market now exists for any of the securities issued by the Company and
that the Company has made no assurances that a public market will ever exist for the Company’s securities.


 


10.Brokers and Finders.
The Investor has not engaged any brokers, finders or agents in connection with the Securities, and the Company has not incurred
nor will incur, directly or indirectly, as a result of any action taken by the Investor, any liability for brokerage or finders’
fees or agents’ commissions or any similar charges in connection with the Securities.


 



    	 



    	 



    

 


11.Legal Counsel.
The Investor has had the opportunity to review the Warrant, the exhibits and schedules attached thereto and the transactions contemplated
by the Warrant with its own legal counsel. The Investor is not relying on any statements or representations of the Company or its
agents for legal advice with respect to this investment or the transactions contemplated by the Warrant.


 


12.Tax Advisors.
The Investor has reviewed with its own tax advisors the U.S. federal, state and local and non-U.S. tax consequences of this investment
and the transactions contemplated by the Warrant. With respect to such matters, the Investor relies solely on such advisors and
not on any statements or representations of the Company or any of its agents, written or oral. The Investor understands that it
(and not the Company) shall be responsible for its own tax liability that may arise as a result of this investment or the transactions
contemplated by the Warrant.
