$ 440,000                                                      February 20, 2002

         FOR VALUE RECEIVED, Chautauqua Airlines, Inc., a New York corporation
(the "Company and "Borrower"), hereby jointly and severally unconditionally
promises to pay on demand to the order of Solitair Corp., a Delaware corporation
("Lender"), at c/o Wexford Capital LLC, 411 West Putnam Avenue, Greenwich,
Connecticut 06830 or at such other place as the holder of this Note may
designate from time to time in writing, in lawful money of the United States of
America and in immediately available funds, the principal amount of four hundred
and forty thousand dollars ($440,000.00) or such lesser amount as may be
outstanding hereunder on or before March 31, 2003, together with interest
(computed on the basis of a 360-day year of twelve 30-day months and compounded
semiannually) (a) on the unpaid balance thereof at the rate of 9% per annum from
the date hereof, (b) to the extent permitted by law, on any overdue payment
(including any overdue prepayment) of principal and any overdue payment of
interest, payable as aforesaid (or, at the option of the holder hereof, on
demand), at a rate per annum equal to 12%.

         Payments of principal of and interest on this Note are to be made in
lawful money of the United States of America at the office of the Company or at
such other place as the Company shall have designated by written notice to the
holder of this Note.

         The Company agrees, and the holder agrees, that the indebtedness
evidenced by this Note is subordinate in right of payment, to the extent and in
the manner provided in this paragraph, to the prior payment in full of all
Senior Debt, and that the subordination is for the benefit of the holders of
Senior Debt. "Senior Debt" means any indebtedness to Fleet Capital Corporation
under the terms of the Loan and Security Agreement dated December 9, 1998 as
amended by Amendment No. 1 to Loan and Security Agreement dated July 27, 1999,
Amendment No. 2 to Loan and Security Agreement dated August 28, 1999, and
Amendment No. 3 to Loan and Security Agreement dated October 29, 2001or as
further amended pursuant to any subsequent amendment. Upon any distribution to
creditors of the Company in a liquidation or dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property, (1) holders of Senior Debt shall be
entitled to receive payment

<Page>

in full in cash of the principal of and interest (including interest accruing
after the commencement of any such proceeding) to the date of payment on the
Senior Debt before the holder shall be entitled to receive any payment of
principal of or interest on this Note; and (2) until the Senior Debt is paid in
full in cash, any distribution to which the holder would be entitled but for
this paragraph shall be made to holders of Senior Debt as their interests may
appear. The Company may not pay principal of or interest on this Note and may
not acquire this Note for cash or property other than capital stock of the
Company if a default on Senior Debt occurs and is continuing that permits
holders of such Senior Debt to accelerate its maturity, and if a distribution is
made to the holder that because of this paragraph should not have been made to
it, the holder who receives the distribution shall hold it in trust for holders
of Senior Debt and pay it over to them as their interests may appear. After all
Senior Debt is paid in full and until this Note is paid in full, the holder
shall be subrogated to the rights of holders of Senior Debt to receive
distributions applicable to Senior Debt to the extent that distributions
otherwise payable to the holders have been applied to the payment of Senior
Debt. Nothing in this paragraph shall impair, as between the Company and the
holder, the obligation of the Company, which is absolute and unconditional, to
pay principal of and interest on this Note in accordance with its terms.

         The Company may prepay this Note, in whole or in part, at any time
together with interest accrued to the date of such prepayment. Upon any sale,
assignment, transfer or other disposition of any stock of Chautauqua Airlines,
Inc., or upon any issuance or sale by the Company or the Company's parent
company of any capital stock, the Company shall prepay principal and interest on
this Note in an amount equal to the cash proceeds of any such disposition,
issuance or sale, net of reasonable costs and expenses and net of any repayments
of indebtedness secured by a lien on any such stock of Chautauqua Airlines, Inc.

         Demand, presentment, protest and notice of nonpayment and protest are
hereby waived by Borrowers.

         This Note shall be interpreted, governed by, and construed in
accordance with, the laws of the State of New York.

         In Witness Whereof, Borrower has caused this Note to be duly executed
and delivered on the date first above written.

                                   CHAUTAUQUA AIRLINES, INC.

entered into between Sensar Corporation, a Nevada corporation (the "Company"), and Joe Kowal (the  "Consultant"). Capitalized terms used in this Amendment
without definition have the meanings specified in the Registration Rights Agreement (as defined
below). 

 
 

Recitals    
  

        A.    The
Company and the Consultant are parties to that certain Registration Rights Agreement (the "Registration Rights
Agreement") dated as of April 23, 2002. 

        B.    The
Company and the Consultant desire to amend the Registration Rights Agreement in order to change certain conditions precedent to the Company's obligations, anticipate
the filing of a Registration Statement on Form S-2, accelerate the termination of applicable registration rights and amend the definition of registrable securities. 

        C.    The
Company and the Consultant also desire to amend other terms of the Registration Rights Agreement as set forth below. 

 
 

Agreement    
  

        In consideration of the agreements contained in this Amendment and in the Registration Rights Agreement, the parties agree as follows: 

        1.    Amendment.    The Registration Rights Agreement is amended as follows: 

	(a)
	Section 2.1
shall be deleted and replaced with the following: 

"2.1 Registration Rights. On or before July 31, 2002, the Company shall file with the Securities Exchange Commission, and use reasonable efforts
to cause to become effective, a Registration Statement on Form S-2 (or other registration statement for which the Company is eligible) registering the re-sale of the
Registrable Securities. This single registration shall fulfill all registration obligations of the Company under the Registration Rights Agreement and, upon the expiration of the time period set forth
in Section 2.3(a), the Registration Rights Agreement shall terminate." 

	(b)
	Section 2.3(a)
shall be deleted and replaced with the following:

	"(a)
	Keep
such registration effective until the earliest to occur of

	(i)
	April 23,
2003; and

	(ii)
	The
date the Consultant is eligible to resell the Registrable Securities pursuant to Rule 144 under the Securities Act without volume
restrictions or filing requirements; and

	(iii)
	The
date the distribution described in the Registration Statement filed pursuant to Section 2.1 above is completed." 

	(c)
	A
new Section 2.9 shall be added and shall read as follows: 

"2.9
Delivery of Company Information to Prospective Purchasers. The Consultant acknowledges and agrees that he must deliver a copy of the prospectus
that is a part of the registration statement filed pursuant to Section 2.1 above to all prospective purchasers of the Registrable Securities. In that regard, in order to be sure that the
prospectus delivered by the Consultant is complete and accurate, if the
Consultant intends to offer or sale any Registrable Securities, he shall deliver written notice to the Company not more than 30 calendar days and not less 

 

than 10 business days prior to any offer or sale of Registrable Securities so that the Company can prepare and deliver to Consultant a current prospectus, including recent annual reports, quarterly
reports and other information included in the prospectus." 

        (d)    Additional Registrable Securities.    The first sentence of the definition of Registrable Securities is deleted
and replaced with the following: 

"Registrable Securities means (i) all of the shares of Common Stock issued or issuable upon exercise of the Warrant; (ii) the 306,250
shares of Common Stock received by the Consultant as a finder's fee under the Consulting and Finders Agreement dated February 13, 2002 between the Consultant and the Company and
(iii) any Common Stock issued in respect of the shares described in clauses (i) and (ii) upon any stock split, stock dividend, recapitalization or other similar event." 

        2.    Restrictions on Additional Registrable Securities.    Notwithstanding the inclusion in the definition of
"Registrable Securities" of the 306,250 shares of Common Stock (the "Finder's Shares") received by Consultant as a finder's fee under the Consulting and Finders Agreement dated February 13,
2002, the Consultant agrees that the Finder's Shares shall not be offered, sold, pledged, hypothecated or otherwise transferred (under a registration statement or otherwise) at any time before
March 1, 2003. In order to ensure compliance with this Section 2, the Company may place a stop transfer order on the Finder's Shares for the period prior to March 1, 2003 and may
place any restrictive legend on (or refuse to remove any legend from) the Finder's Shares during the period between the date of this Amendment and March 1, 2003. 

        3.    No Other Amendments.    Except as expressly provided in this Amendment, the Registration Rights Agreement is not
otherwise modified and remains in full force and effect. 

        4.    Legal Counsel.    The Consultant acknowledges that Stoel Rives LLP represents only the Company and that the
Company and Stoel Rives LLP have recommend to the Consultant that he obtain legal counsel to review and advise him with respect to this Amendment and that Consultant has had an opportunity to so
obtain and consult with legal counsel.
