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

1.Investment Intent.The Holder is acquiring the Securities for investment for his own account, not as a
nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof.

2.Investment Experience.The Holder has substantial experience in evaluating and investing in private placement
transactions of securities in companies similar to the Company so that he is capable of
evaluating the merits and risks of his investment in the Company and has the capacity to protect his own interests.

3.Speculative Nature of Investment.The Holder acknowledges that his investment in the Company is highly
speculative and entails a substantial degree of risk and the Holder is in a position to lose the entire amount of such investment.

4.Access to Data.The Holder has had an opportunity to discuss the Company's business, management and financial
affairs with the Company's management. The Holder has also had an opportunity to ask questions of officers of the Company, which questions were answered to its satisfaction. The Holder understands
that 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 Holder 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 he can be expected that some or all of the assumptions underlying the projections will not materialize or will vary significantly from
actual results.

5.Accredited Investor.The Holder is an "accredited investor" within the meaning of Regulation D,
Rule 501(a), promulgated by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Securities Act").

6.Residency.The residency of the Holder (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.

7.Restriction on Resales.The Holder acknowledges that the Securities must be held indefinitely unless
subsequently registered under the Securities Act or unless an exemption from such registration is available. The Holder further understands that there is no assurance that any exemption from
registration under the Securities Act will be available or, if available, that such exemption will allow the Holder to dispose of or otherwise transfer any or all of the Securities under the
circumstances, in the amounts or at the times the Holder might propose.

8.Rule 144.The Holder is aware of the provisions of Rule 144 promulgated under the Securities
Act which permit limited resale of shares purchased in a private placement subject to the

Exhibit C - Page 1

---

satisfaction of certain conditions, including among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale
occurring not less than one year after a party has purchased and paid for the security to be sold, the sale being effected through a "broker's transaction" or in transactions directly with a "market
maker" and the number of shares being sold during any three-month period not exceeding specified limitations. The Holder acknowledges that, in the event all of the 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 Holder 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 such offers or sales and that such persons and the brokers who participate
in the transactions do so at their own risk.

9.Authorization.The Holder has all requisite power and authority to execute and deliver the Warrant, to
purchase the Securities and to carry out and perform its obligations under the terms of the Warrant. All action on the part of the Holder necessary for the authorization, execution, delivery and
performance of the Warrant, and the performance of all of the Holder's obligations under the Warrant, has been taken or will be taken prior to the purchase of the Warrant.



10.Brokers or Finders.The Holder has not engaged any brokers, finders or agents, and the Company has not
incurred and will not incur, directly or indirectly, as a result of any action taken by the Holder, any liability for brokerage or finders' fees or agents' commissions or any similar charges in
connection with the Warrant.

11.Investor Counsel.The Holder acknowledges that he has had the opportunity to review the Warrant and the
exhibits attached thereto and the transactions contemplated by the Warrant with his own legal counsel. The Holder is relying solely on such counsel and not 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 Holder has reviewed with his own tax advisors the U.S. federal, state, local and foreign
tax consequences of this investment and the transactions contemplated by the Warrant. With respect to such matters, the Holder relies solely on such advisors and not on any statements or
representations of the Company or any of its agents, written or oral. The Holder understands that it (and not the Company) shall be responsible for his own tax liability that may arise as a result of
this investment or the transactions contemplated by the Warrant.

13.Further Limitations on Disposition.Without in any way limiting the representations and warranties set forth
above, the Holder agrees not to make any disposition of all or any portion of the Securities unless and until, and it shall be a condition to the transfer of all or any portion of the Securities that:
(1) there is then in effect a registration statement under the Securities Act covering

Exhibit C - Page 2

---

such proposed disposition and such disposition is made in accordance with such registration statement or (2) (A) the Holder shall have notified the Company of the proposed disposition and
shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, (B) the transferee shall have agreed in writing to be bound by and subject
to the terms, conditions, restrictions, obligations and other limitations set forth in the Warrant to the same extent as if such transferee were the original Holder thereunder, (C) the
transferee shall have confirmed to the satisfaction of the Company in writing, substantially in the form attached to the Warrant asExhibit C,
that the Securities are being acquired solely for the transferee's own account and not as a nominee for any other party, for investment and not with a view toward distribution or resale and that the
transferee shall have confirmed such other matters related thereto as may be reasonably requested by the Company, and (D) if requested by the Company, the Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of the Securities under the Securities Act. The Securities that are
transferred to a transferee shall be subject to the terms, conditions, restrictions, obligations and other limitations set forth herein and therein.

(The remainder of this page is intentionally left blank.)
