- --------------------------------------------------------------------------------


$3,000,000.00                                                OAKLAND, CALIFORNIA
                                                               NOVEMBER 30, 1998

     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 850, 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, 1998.

     (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.

     (d)  Collation of Payments. Borrower authorizes Bank to collect all 
interest due hereunder by charging Borrower's demand deposit account number 
4187-518166 with Bank, or any other demand deposit account maintained by any 
Borrower with Bank, for the full amount thereof. Should there be insufficient 
funds in any such demand deposit account to pay all such sums when due, the 
full amount of such deficiency shall be immediately due and payable by Borrower.

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, 1999.

     (b)  Advances. Advances hereunder, to the total amount of the principal 
sum available hereunder, may be made by the holder at the oral or written 
request of (i) WARREN PINCKERT AND/OR ANDREA TILLER AND/OR CECILIA AGUILAR, any 
one acting alone, 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 
credited first, to any interest then due and second, to the outstanding 
principal balance hereof.

EVENTS OF DEFAULT:

     The occurrence of any of the following shall constitute an "Event of 
Default" under this Note:

     (a)  The failure to pay any principal, interest, fees or other charges 
when due hereunder or under any contract, instrument or document executed in 
connection with this Note.

     (b)  The filing of a petition by or against any Borrower, any guarantor of 
this Note or any general partner or joint venturer in any Borrower which is a

and/or joint venturer referred to herein as a "Third Party Obligor") under any 
provisions of the Bankruptcy Reform Act, Title 11 of the United States Code, as 
amended or recodified from time to time, or

is generally not paying its debts as they become due; or any attachment or like 
levy on any property of any Borrower or Third Party Obligor.

     (c)  The death or incapacity of any individual Borrower or Third Party 
Obligor, or the dissolution or liquidation of any Borrower or Third Party 
Obligor which is a corporation, partnership, joint venture or other type of 
entity.

     (d)  Any default in the payment or performance of any obligation, or any 
defined event of default, under any provisions of any contract, instrument or 
document pursuant to which any Borrower or Third Party Obligor has incurred any 
obligation for borrowed money, any purchase obligation, or any other liability 
of any kind to any person or entity, including the holder.

     (e)  Any financial statement provided by any Borrower or Third Party 
Obligor to Bank proves to be incorrect, false or misleading in any material 
respect.

     (f)  Any sale or transfer of all or a substantial or material part of the 
assets of any Borrower or Third Party Obligor other than in the ordinary course 
of its business.

     (g)  Any violation or breach of any provision of, or any defined event of 
default under, any addendum to this Note or any loan agreement, guaranty, 
security agreement, deed of trust, mortgage or other document executed in 
connection with or securing this Note.

MISCELLANEOUS:

     (a)  Remedies.  Upon the occurrence of any Event of Default, the holder of 
this Note, at the holder's option, may declare all sums of principal and 
interest outstanding hereunder to be immediately due and payable without 
presentment, demand, notice of nonperformance, notice of protest, protest or 
notice of dishonor, all of which are expressly waived by each Borrower, and the 
obligation, if any, of the holder to extend any further credit hereunder shall 
immediately cease and terminate. Each Borrower shall pay to the holder 
immediately upon demand the full amount of all payments, advances, charges, 
costs and expenses, including reasonable attorneys' fees (to include outside 
counsel fees and all allocated costs of the holder's in-house counsel), 
expended or incurred by the holder in connection with the enforcement of the 
holder's rights and/or the collection of any amounts which become due to the 
holder under this Note, and the prosecution or defense of any action in any way 
related to this Note, including without limitation, any action for declaratory 
relief, whether incurred at the trial or appellate level, in any arbitration 
proceeding or otherwise, and including any of the foregoing incurred in 
connection with any bankruptcy proceeding (including without limitation, any 
adversary proceeding, contested matter or motion brought by Bank or any other 
person) relating to any Borrower or any other person or entity.

     (b)  Obligations Joint and Several.  Should more than one person or entity 
sign this Note as a Borrower, the obligations of each such Borrower shall be 
joint and several.

     (c)  Governing Law.  This Note shall be governed by and construed in 
accordance with the laws of the state of California.

     IN WITNESS WHEREOF, the undersigned has executed this Note as of the date 
first written above.
