time pursuant to Section 5 hereof (the "Warrant Price"), subject to the provisions and upon the terms and conditions hereinafter set forth and callable by the Company upon the terms and

hereafter be converted or exchanged.

1.Term of Warrant.

The
purchase right represented by this Warrant is exercisable, in whole or in part, at any time during a period beginning on May 15, 2000 and ending May 15, 2003.

of exercise form attached hereto, as Exhibit 1 duly executed) at the principal office of the Company and by the payment to the Company, by cashier's check or wire transfer, of an amount equal
to the then applicable Warrant Price per share multiplied by the number of shares then being purchased. The Company agrees that the shares so purchased shall be deemed to be issued to the Holder as
the record owner of such shares as of the close of business on the date on which this Warrant shall have been surrendered and payment made for such shares as aforesaid. In the event of any exercise of

4.Stock Fully Paid; Reservation of Shares.

All
Common Stock which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all United States
taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and
reserved for the purpose of the issuance upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights
represented by this Warrant.

5.Adjustment of Purchase Price and Number of Shares.

The
kind of securities purchasable upon the exercise of this Warrant, the Warrant Price and the number of shares purchasable upon exercise of this Warrant shall be subject to adjustment
from time to time upon the occurrence of the following events:

(a)Reclassification, Consolidation, or Merger.In case of any reclassification or change of outstanding
securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision
or combination), or in case of any consolidation or merger of the Company with or into another corporation, other than a Merger with another corporation in which the Company is a continuing
corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant, the Company, or such successor, as the case may be, shall
execute a new Warrant, providing that the Holder of this Warrant shall have the right to exercise such new Warrant and procure upon such exercise, in lieu of each share of Common Stock theretofore
issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification, change, consolidation, or merger by a Holder
of one share of Common Stock; provided, however, that the Board of Directors of the Company may determine that, upon the occurrence of any of the following listed events, this Warrant will become
immediately exercisable, in whole or in part, on such date of occurrence and if unexercised, in whole or in part, by the Holder, will thereupon terminate: (i) a stockholder approved dissolution
or liquidation of the Company; (ii) a stockholder approved sale of substantially all of the Company's business and/or assets to a person or entity that is not a subsidiary or affiliate of the
Company; or (iii) any consolidation or merger of the Company with or into one or more entities that are not subsidiaries or other affiliates of the Company where the Company does not survive.
Any new Warrant shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5. The provisions of this subparagraph
(a) shall similarly apply to successive reclassification, changes, consolidations, and mergers.

(b)Subdivision or Combination of Shares.If the Company at any time while this Warrant remains outstanding and
unexpired shall subdivide or combine its common stock, or distribute dividends on its common stock payable in Common Stock, the Warrant Price shall be proportionately decreased in the case of a
subdivision or increased in the case of a combination or dividend.

(c)Adjustment of Number of Shares.Upon each adjustment in the Warrant Price pursuant to any of subparagraphs
(a) through (c) of this Section 5, the number of shares of Common Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying
the number of shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the
denominator of which shall be the Warrant Price immediately thereafter.

2

---

6.Notice of Adjustments.

Whenever
any Warrant Price shall be adjusted pursuant to Section 5 hereof, the Company shall prepare a certificate signed by its chief financial officer setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, the Warrant Price after giving effect to such adjustment and
the number of shares then purchasable upon exercise of this Warrant, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder of this Warrant at the
address specified in Section 10(c) hereof, or at such other address as may be provided to the Company in writing by the Holder of this Warrant.

7.Fractional Shares.

No
fractional shares of Common Stock will be issued in conjunction with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefore on
the basis of the Warrant Price then in effect.

8.Compliance with Securities Act.

The
Holder of this Warrant, by acceptance hereof, agrees that this Warrant and the shares of Common Stock to be issued on exercise hereof are being acquired for investment and that it
will not offer, sell or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the

SATISFACTORY TO THE COMPANY IS FURNISHED TO THE COMPANY TO THE EFFECT THAT REGISTRATION UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED."

9.Transfer and Exchange of Warrant.

This
Warrant is not transferable or exchangeable without the consent of the Company.

10.Miscellaneous.

(a)No Rights as Shareholder.The Holder of this Warrant shall not be entitled to vote or receive dividends or
be deemed the Holder of Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to
confer upon the Holder of this Warrant, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at
any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to
no par value, consolidation, merger, conveyance or other vise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until the Warrant shall have been exercised
and the shares purchasable upon the exercise hereof shall have become deliverable, as provided herein.

(b)Replacement.On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction,
or mutilation of this Warrant and, in the case of mutilation, on surrender and

taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this

from time to time upon the occurrence of the following events:

(a)Reclassification, Consolidation, or Merger.In case of any reclassification or change of outstanding
securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision
or combination), or in case of any consolidation or merger of the Company with or into another corporation, other than a Merger with another corporation in which the Company is a continuing

issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification, change, consolidation, or merger by a Holder
of one share of Common Stock; provided, however, that the Board of Directors of the Company may determine that, upon the occurrence of any of the following listed events, this Warrant will become
immediately exercisable, in whole or in part, on such date of occurrence and if unexercised, in whole or in part, by the Holder, will thereupon terminate: (i) a stockholder approved dissolution
or liquidation of the Company; (ii) a stockholder approved sale of substantially all of the Company's business and/or assets to a person or entity that is not a subsidiary or affiliate of the
Company; or (iii) any consolidation or merger of the Company with or into one or more entities that are not subsidiaries or other affiliates of the Company where the Company does not survive.
Any new Warrant shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5. The provisions of this subparagraph
(a) shall similarly apply to successive reclassification, changes, consolidations, and mergers.

(b)Subdivision or Combination of Shares.If the Company at any time while this Warrant remains outstanding and
unexpired shall subdivide or combine its common stock, or distribute dividends on its common stock payable in Common Stock, the Warrant Price shall be proportionately decreased in the case of a
subdivision or increased in the case of a combination or dividend.

(c)Adjustment of Number of Shares.Upon each adjustment in the Warrant Price pursuant to any of subparagraphs
(a) through (c) of this Section 5, the number of shares of Common Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying
the number of shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the
denominator of which shall be the Warrant Price immediately thereafter.

6.Notice of Adjustments.

Whenever
any Warrant Price shall be adjusted pursuant to Section 5 hereof, the Company shall prepare a certificate signed by its chief financial officer setting forth, in
reasonable detail, the event

12

Section 10(c) hereof, or at such other address as may be provided to the Company in writing by the Holder of this Warrant.

fractional shares of Common Stock will be issued in conjunction with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefore on
the basis of the Warrant Price then in effect.

8.Compliance with Securities Act.

The
Holder of this Warrant, by acceptance hereof, agrees that this Warrant and the shares of Common Stock to be issued on exercise hereof are being acquired for investment and that it
will not offer, sell or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the

THE EFFECT THAT REGISTRATION UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED."

9.Transfer and Exchange of Warrant.

This
Warrant is not transferable or exchangeable without the consent of the Company.

10.Miscellaneous.

(a)No Rights as Shareholder.The Holder of this Warrant shall not be entitled to vote or receive dividends or
be deemed the Holder of Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to

no par value, consolidation, merger, conveyance or other vise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until the Warrant shall have been exercised
and the shares purchasable upon the exercise hereof shall have become deliverable, as provided herein.

or mutilation of this Warrant and, in the case of mutilation, on surrender and cancellation of this Warrant, the Company, at the Holder's expense, will execute and deliver, in lieu of this Warrant, a
new Warrant of like tenor.

taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issuance upon exercise of the purchase rights evidenced by this Warrant, a sufficient
number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant.

5.Adjustment of Purchase Price and Number of Shares.

The
kind of securities purchasable upon the exercise of this Warrant, the Warrant Price and the number of shares purchasable upon exercise of this Warrant shall be subject to adjustment
from time to time upon the occurrence of the following events:

(a)Reclassification, Consolidation, or Merger.In case of any reclassification or change of outstanding
securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision
or combination), or in case of any consolidation or merger of the Company with or into another corporation, other than a Merger with another corporation in which the Company is a continuing
corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant, the Company, or such successor, as the case may be, shall
execute a new Warrant, providing that the Holder of this Warrant shall have the right to exercise such new Warrant and procure upon such exercise, in lieu of each share of Common Stock theretofore
issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification, change, consolidation, or merger by a Holder
of one share of Common Stock; provided, however, that the Board of Directors of the Company may determine that, upon the occurrence of any of the following listed events, this Warrant will become
immediately exercisable, in whole or in part, on such date of occurrence and if unexercised, in whole or in part, by the Holder, will thereupon terminate: (i) a stockholder approved dissolution
or liquidation of the Company; (ii) a stockholder approved sale of substantially all of the Company's business and/or assets to a person or entity that is not a subsidiary or affiliate of the
Company; or (iii) any consolidation or merger of the Company with or into one or more entities that are not subsidiaries or other affiliates of the Company where the Company does not survive.
Any new Warrant shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5. The provisions of this subparagraph
(a) shall similarly apply to successive reclassification, changes, consolidations, and mergers.

(b)Subdivision or Combination of Shares.If the Company at any time while this Warrant remains outstanding and
unexpired shall subdivide or combine its common stock, or distribute dividends on its common stock payable in Common Stock, the Warrant Price shall be proportionately decreased in the case of a
subdivision or increased in the case of a combination or dividend.

(c)Adjustment of Number of Shares.Upon each adjustment in the Warrant Price pursuant to any of subparagraphs
(a) through (c) of this Section 5, the number of shares of Common Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying
the number of shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the
denominator of which shall be the Warrant Price immediately thereafter.

6.Notice of Adjustments.

Whenever
any Warrant Price shall be adjusted pursuant to Section 5 hereof, the Company shall prepare a certificate signed by its chief financial officer setting forth, in
reasonable detail, the event

22

---

requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, the Warrant Price after giving effect to such adjustment and the number of shares then
purchasable upon exercise of this Warrant, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder of this Warrant at the address specified in
Section 10(c) hereof, or at such other address as may be provided to the Company in writing by the Holder of this Warrant.

7.Fractional Shares.

No
fractional shares of Common Stock will be issued in conjunction with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefore on
the basis of the Warrant Price then in effect.

8.Compliance with Securities Act.

The
Holder of this Warrant, by acceptance hereof, agrees that this Warrant and the shares of Common Stock to be issued on exercise hereof are being acquired for investment and that it
will not offer, sell or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the
Securities Act of 1933, as amended (the "Act"). This Warrant and all shares of Common Stock issued upon exercise of this Warrant (unless registered under the Act) shall be stamped and imprinted with a
legend substantially in the following form:

BEEN REGISTERED UNDER THE ACT AND SUCH LAWS OR (1) REGISTRATION UNDER SUCH LAWS IS NOT REQUIRED AND (2) AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY IS FURNISHED TO THE COMPANY TO
THE EFFECT THAT REGISTRATION UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED."

9.Transfer and Exchange of Warrant.

This
Warrant is not transferable or exchangeable without the consent of the Company.

10.Miscellaneous.

(a)No Rights as Shareholder.The Holder of this Warrant shall not be entitled to vote or receive dividends or
be deemed the Holder of Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to
confer upon the Holder of this Warrant, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at
any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to
no par value, consolidation, merger, conveyance or other vise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until the Warrant shall have been exercised
and the shares purchasable upon the exercise hereof shall have become deliverable, as provided herein.

(b)Replacement.On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction,
or mutilation of this Warrant and, in the case of mutilation, on surrender and cancellation of this Warrant, the Company, at the Holder's expense, will execute and deliver, in lieu of this Warrant, a
new Warrant of like tenor.

All
Common Stock which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be fully paid and nonassessable, and free from all United States
taxes, liens and charges with respect to the issue thereof. During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of the issuance upon exercise of the purchase rights evidenced by this Warrant, a sufficient

5.Adjustment of Purchase Price and Number of Shares.

The
kind of securities purchasable upon the exercise of this Warrant, the Warrant Price and the number of shares purchasable upon exercise of this Warrant shall be subject to adjustment

(a)Reclassification, Consolidation, or Merger.In case of any reclassification or change of outstanding
securities of the class issuable upon exercise of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision
or combination), or in case of any consolidation or merger of the Company with or into another corporation, other than a Merger with another corporation in which the Company is a continuing
corporation and which does not result in any reclassification or change of outstanding securities issuable upon exercise of this Warrant, the Company, or such successor, as the case may be, shall
execute a new Warrant, providing that the Holder of this Warrant shall have the right to exercise such new Warrant and procure upon such exercise, in lieu of each share of Common Stock theretofore
issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification, change, consolidation, or merger by a Holder
of one share of Common Stock; provided, however, that the Board of Directors of the Company may determine that, upon the occurrence of any of the following listed events, this Warrant will become
immediately exercisable, in whole or in part, on such date of occurrence and if unexercised, in whole or in part, by the Holder, will thereupon terminate: (i) a stockholder approved dissolution
or liquidation of the Company; (ii) a stockholder approved sale of substantially all of the Company's business and/or assets to a person or entity that is not a subsidiary or affiliate of the
Company; or (iii) any consolidation or merger of the Company with or into one or more entities that are not subsidiaries or other affiliates of the Company where the Company does not survive.
Any new Warrant shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5. The provisions of this subparagraph
(a) shall similarly apply to successive reclassification, changes, consolidations, and mergers.

(b)Subdivision or Combination of Shares.If the Company at any time while this Warrant remains outstanding and
unexpired shall subdivide or combine its common stock, or distribute dividends on its common stock payable in Common Stock, the Warrant Price shall be proportionately decreased in the case of a
subdivision or increased in the case of a combination or dividend.

(c)Adjustment of Number of Shares.Upon each adjustment in the Warrant Price pursuant to any of subparagraphs
(a) through (c) of this Section 5, the number of shares of Common Stock purchasable hereunder shall be adjusted, to the nearest whole share, to the product obtained by multiplying
the number of shares purchasable immediately prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the
denominator of which shall be the Warrant Price immediately thereafter.

6.Notice of Adjustments.

Whenever
any Warrant Price shall be adjusted pursuant to Section 5 hereof, the Company shall prepare a certificate signed by its chief financial officer setting forth, in
reasonable detail, the event

32

---

requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, the Warrant Price after giving effect to such adjustment and the number of shares then
purchasable upon exercise of this Warrant, and shall cause copies of such certificate to be mailed (by first class mail, postage prepaid) to the Holder of this Warrant at the address specified in
Section 10(c) hereof, or at such other address as may be provided to the Company in writing by the Holder of this Warrant.

7.Fractional Shares.

No
fractional shares of Common Stock will be issued in conjunction with any exercise hereunder, but in lieu of such fractional shares the Company shall make a cash payment therefore on
the basis of the Warrant Price then in effect.

8.Compliance with Securities Act.

The
Holder of this Warrant, by acceptance hereof, agrees that this Warrant and the shares of Common Stock to be issued on exercise hereof are being acquired for investment and that it
will not offer, sell or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon exercise hereof except under circumstances which will not result in a violation of the
Securities Act of 1933, as amended (the "Act"). This Warrant and all shares of Common Stock issued upon exercise of this Warrant (unless registered under the Act) shall be stamped and imprinted with a
legend substantially in the following form:

BEEN REGISTERED UNDER THE ACT AND SUCH LAWS OR (1) REGISTRATION UNDER SUCH LAWS IS NOT REQUIRED AND (2) AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY IS FURNISHED TO THE COMPANY TO
THE EFFECT THAT REGISTRATION UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED."

9.Transfer and Exchange of Warrant.

This
Warrant is not transferable or exchangeable without the consent of the Company.

10.Miscellaneous.

(a)No Rights as Shareholder.The Holder of this Warrant shall not be entitled to vote or receive dividends or
be deemed the Holder of Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to
confer upon the Holder of this Warrant, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at
any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value or change of stock to
no par value, consolidation, merger, conveyance or other vise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until the Warrant shall have been exercised
and the shares purchasable upon the exercise hereof shall have become deliverable, as provided herein.

(b)Replacement.On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction,
or mutilation of this Warrant and, in the case of mutilation, on surrender and cancellation of this Warrant, the Company, at the Holder's expense, will execute and deliver, in lieu of this Warrant, a
new Warrant of like tenor.
