     FOR VALUE RECEIVED, the undersigned CHOLESTECH CORPORATION ("Borrower") 
promises to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION 
("Bank") at its office at EAST BAY RCBO, ONE KAISER PLAZA SUITE 860, OAKLAND, 
CA 94612, or at such other place as the holder hereof may designate, in 
lawful money of the United States of America and in immediately available 
funds, the principal sum of $3,000,000.00, or so much thereof as may be 
advanced and be outstanding, with interest thereon, to be computed on each 
advance from the date of its disbursement as set forth herein.

INTEREST:

     (a)  INTEREST.  The outstanding principal balance of this Note shall 
bear interest (computed on the basis of a 360-day year, actual days elapsed) 
at a rate per annum equal to the Prime Rate in effect from time to time.  The 
"Prime Rate" is a base rate that Bank from time to time establishes and which 
serves as the basis upon which effective rates of interest are calculated for 
those loans making reference thereto.  Each change in the rate of interest 
hereunder shall become effective on the date each Prime Rate change is 
announced within Bank.

     (b)  PAYMENT OF INTEREST.  Interest accrued on this Note shall be payable
on the last day of each month, commencing DECEMBER 31, 1996.

     (c)  DEFAULT INTEREST.  From and after the maturity date of this Note, 
or such earlier date as all principal owing hereunder becomes due and payable 
by acceleration or otherwise, the outstanding principal balance of this Note 
shall bear interest until paid in full at an increased rate per annum 
(computed on the basis of a 360-day year, actual days elapsed) equal to 4% 
above the rate of interest from time to time applicable to this Note.

BORROWING AND REPAYMENT:

     (a)  BORROWING AND REPAYMENT.  Borrower may from time to time during the 
term of this Note borrow, partially or wholly repay its outstanding 
borrowings, and reborrow, subject to all of the limitations, terms and 
conditions of this Note and of any document executed in connection with or 
governing this Note; provided however, that the total outstanding borrowings 
under this Note shall not at any time exceed the principal amount stated 
above.  The unpaid principal balance of this obligation at any time shall be 
the total amounts advanced hereunder by the holder hereof less the amount of 
principal payments made hereon by or for any Borrower, which balance may be 
endorsed hereon from time to time by the holder.  The outstanding principal 
balance of this Note shall be due and payable in full on NOVEMBER 30, 1997.

two acting together, who are authorized to request advances and direct the 
disposition of any advances until written notice of the revocation of such 
authority is received by the holder at the office designated above, or (ii) 
any person, with respect to advances deposited to the credit of any account 
of any Borrower with the holder, which advances, when so deposited, shall be 
conclusively presumed to have been made to or for the benefit of each 
Borrower regardless of the fact that persons other than those authorized to 
request advances may have authority to draw against such account.  The holder 
shall have no obligation to determine whether any person requesting an 
advance is or has been authorized by any Borrower.

     (c)  APPLICATION OF PAYMENTS. Each payment made on this Note shall be
