Dear Sir:

     This letter is to confirm that Wells Fargo Bank, National Association 
("Bank"), subject to all terms and conditions contained herein, has agreed to 
make available to CHOLESTECH CORPORATION ("Borrower") a revolving line of 
credit under which Bank will make advances to Borrower from time to time up 
to and including November 30, 1997, not to exceed at any time the maximum 
principal amount of Three Million Dollars ($3,000,000.00) ("Line of Credit"), 
the proceeds of which shall be used to support Borrower's working capital 
requirements.

I.   CREDIT TERMS:

     1.   LINE OF CREDIT:

     (a)  LINE OF CREDIT NOTE.  Borrower's obligation to repay advances under 
the Line of Credit shall be evidenced by a promissory note substantially in 
the form of Exhibit A attached hereto ("Line of Credit Note"), all terms of 
which are incorporated herein by this reference.

     (b)  BORROWING AND REPAYMENT.  Borrower may from time to time during the 
term of the Line of Credit borrow, partially or wholly repay its outstanding 
borrowings, and reborrow, subject to all of the limitations, terms and 
conditions contained herein or in the Line of Credit Note; provided however, 
that the total outstanding borrowings under the Line of Credit shall not at 
any time exceed the maximum principal amount available thereunder, as set 
forth above.
     
     2.   COLLATERAL:

     As security for all indebtedness of Borrower to Bank subject hereto, 
Borrower hereby grants to Bank security interests of first priority in all

     All of the foregoing shall be evidenced by and subject to the terms of 
such security agreements, financing statements, deeds of trust and other 
documents as Bank shall reasonably require, all in form and substance 
satisfactory to Bank. Borrower shall reimburse Bank immediately upon demand 
for all costs and expenses incurred by Bank in connection with any of the 
foregoing security, including without limitation, filing and recording fees 
and costs of appraisals, audits and title insurance. Security interest

of a 360-day year, actual days elapsed.  Interest shall be payable at the 
times and place set forth in the Line of Credit Note.

     3.   COLLECTION OF PAYMENTS. Borrower authorizes Bank to collect all 
interest due under the Line of Credit by charging Borrower's demand deposit 
account number 4187-516166 with  Bank, or any other demand deposit account 
maintained by 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.

III. REPRESENTATIONS AND WARRANTIES:

     Borrower makes the following representations and warranties to Bank, 
which representations and warranties shall survive the execution of this 
letter and shall continue in full force and effect until the full and final 
payment, and satisfaction and discharge, of all obligations of Borrower to 
Bank subject to this letter.

     1.   LEGAL STATUS.  Borrower is a corporation, duly organized and 
existing and in good standing under the laws of the state of California, and 
is qualified or licensed to do business in all jurisdictions in which such 
qualification or licensing is required or in which the failure to so qualify 
or to be so licensed could have a material adverse effect on Borrower.

     2.   AUTHORIZATION AND VALIDITY.  This letter, the Line of Credit Note, 
and each other document, contract or instrument deemed necessary by Bank to 
evidence any extension of credit to Borrower pursuant to the terms and 
conditions hereof, or now or at any time hereafter required by or delivered 
to Bank in connection with this letter (collectively, the "Loan Documents") 
have been duly authorized, and upon their execution and delivery in 
accordance with the provisions hereof will constitute legal, valid and 
binding agreements and obligations of Borrower or the party which executes 
the same, enforceable in accordance with their respective terms.

     3.   NO VIOLATION.  The execution, delivery and performance by Borrower 
of each of the Loan Documents do not violate any provision of any law or 
regulation, or contravene any provision of the Articles of Incorporation or 
By-Laws of Borrower, or result in a breach of or constitute a default under 
any contract, obligation, indenture or other instrument to which Borrower is 
a party or by which Borrower may be bound.

     4.   LITIGATION.  There are no pending, or to the best of Borrower's 
knowledge threatened, actions, claims, investigations, suits or proceedings 
by or before any governmental authority, arbitrator, court or administrative 
agency which could have a material adverse effect on the financial condition 
or operation of Borrower other than those disclosed by Borrower to Bank in 
writing prior to the date hereof.

     5.   CORRECTNESS OF FINANCIAL STATEMENT.  The financial statement of 
Borrower dated June 28, 1996, a true copy of which has been delivered by 
Borrower to Bank prior to the date hereof, (a) is complete and correct and 
presents fairly the financial condition of Borrower, (b) discloses all 
liabilities of Borrower that are required to be reflected or reserved against 
under generally accepted accounting principles, whether liquidated or 
unliquidated, fixed or contingent, and (c) has been prepared in accordance 
with generally accepted accounting principles consistently applied. Since the 
date of such financial statement there has been no material adverse change in 
the financial condition of Borrower, nor has Borrower mortgaged, pledged, 
granted a security interest in or otherwise encumbered any of its assets or 
properties except in favor of Bank or as otherwise permitted by Bank in 
writing.

     6.   INCOME TAX RETURNS.  Borrower has no knowledge of any pending 
assessments or adjustments of its income tax payable with respect to any year.

     7.   NO SUBORDINATION.  There is no agreement, indenture, contract or 
instrument to which Borrower is a party or by which Borrower may be bound 
that requires the subordination in right of payment of any of Borrower's 
obligations subject to this letter to any other obligation of Borrower.

     8.   PERMITS, FRANCHISES.  Borrower possesses, and will hereafter 
possess, all permits, consents, approvals, franchises and licenses required 
and all rights to trademarks, trade names, patents and fictitious names, if 
any, necessary to enable it to conduct the business in which it is now 
engaged in compliance with applicable law.

     9.   ERISA.  Borrower is in compliance in all material respects with all 
applicable provisions of the Employee Retirement Income Security Act of 1974, 
as amended or recodified from time to time ("ERISA"); Borrower has not 
violated any provision of any defined employee pension benefit plan (as 
defined in ERISA) maintained or contributed to by Borrower (each, a "Plan"); 
no Reportable Event, as defined in ERISA, has occurred and is continuing with 
respect to any Plan initiated by Borrower; Borrower has met its minimum 
funding requirements under ERISA with respect to each Plan; and each Plan 
will be able to fulfill its benefit obligations as they come due in 
accordance with the Plan documents and under generally accepted accounting 
principles.

     10.  OTHER OBLIGATIONS.  Borrower is not in default on any obligation 
for borrowed money, any purchase money obligation or any other material 
lease, commitment, contract, instrument or obligation.

     11.  ENVIRONMENTAL MATTERS. Except as disclosed by Borrower to Bank in 
writing prior to the date hereof, Borrower is in compliance in all material 
respects with all applicable federal or state environmental, hazardous waste, 
health and safety statutes, and any rules or regulations adopted pursuant 
thereto, which govern or affect any of Borrower's operations and/or 
properties, including without limitation, the Comprehensive Environmental 
Response, Compensation and Liability Act of 1980, the Superfund Amendments 
and Reauthorization Act of 1986, the Federal Resource Conservation and 
Recovery Act of 1976, and the Federal Toxic Substances Control Act, as any of 
the same may be amended, modified or supplemented from time to time.  None of 
the operations of Borrower is the subject of any federal or state 
investigation evaluating whether any remedial action involving a material 
expenditure is needed to respond to a release of any toxic or hazardous waste 
or substance into the environment. Borrower has no material contingent 
liability in connection with

any release of any toxic or hazardous waste or substance into the environment.

     8.   ARBITRATION.

     (a)  ARBITRATION.  Upon the demand of any party, any Dispute shall be 
resolved by binding arbitration (except as set forth in (e) below) in 
accordance with the terms of this letter, A "Dispute" shall mean any action, 
dispute, claim or controversy of any kind, whether in contract or tort, 
statutory or common law, legal or equitable, now existing or hereafter 
arising under or in connection with, or in any way pertaining to, any of the 
Loan Documents, or any past, present or future extensions of credit and other 
activities, transactions or obligations of any kind related directly or 
indirectly to any of the Loan Documents, including without limitation, any of 
the foregoing arising in connection with the exercise of any self-help, 
ancillary or other remedies pursuant to any of the Loan Documents. Any party 
may by summary proceedings bring an action in court to compel arbitration of 
a Dispute.  Any party who fails or refuses to submit to arbitration following 
a lawful demand by any other party shall bear all costs and expenses incurred 
by such other party in compelling arbitration of any Dispute.

     (b)  GOVERNING RULES.  Arbitration proceedings shall be administered by 
the American Arbitration Association ("AAA") or such other administrator as 
the parties shall mutually agree upon



Cholestech Corporation
November 19, 1996
Page 11



in accordance with the AAA Commercial Arbitration Rules.  All Disputes 
submitted to arbitration shall be resolved in accordance with the Federal 
Arbitration Act (Title 9 of the United States Code), notwithstanding any 
conflicting choice of law provision in any of the Loan Documents. The 
arbitration shall be conducted at a location in California selected by the 
AAA or other administrator.  If there is any inconsistency between the terms 
hereof and any such rules, the terms and procedures set forth herein shall 
control. All statutes of limitation applicable to any Dispute shall apply to 
any arbitration proceeding.  All discovery activities shall be expressly 
limited to matters directly relevant to the Dispute being arbitrated. 
Judgment upon any award rendered in an arbitration may be entered in any 
court having jurisdiction; provided however, that nothing contained herein 
shall be deemed to be a waiver by any party that is a bank of the protections 
afforded to it under 12 U.S.C. Section 91 or any similar applicable state law.

     (c)  NO WAIVER; PROVISIONAL REMEDIES, SELF-HELP AND FORECLOSURE.  No 
provision hereof shall limit the right of any party to exercise self-help 
remedies such as setoff, foreclosure against or sale of any real or personal 
property collateral or security, or to obtain provisional or ancillary 
remedies, including without limitation injunctive relief, sequestration, 
attachment, garnishment or the appointment of a receiver, from a court of 
competent jurisdiction before, after or during the pendency of any 
arbitration or other proceeding.  The exercise of any such remedy shall not 
waive the right of any party to compel arbitration or reference hereunder.

     (d)  ARBITRATOR QUALIFICATIONS AND POWERS; AWARDS. Arbitrators must be 
active members of the California State Bar or retired judges of the state or 
federal judiciary of California, with expertise in the substantive law 
applicable to the subject matter of the Dispute.  Arbitrators are empowered 
to resolve Disputes by summary rulings in response to motions filed prior to 
the final arbitration hearing.  Arbitrators (i) shall resolve all Disputes in 
accordance with the substantive law of the state of California, (ii) may 
grant any remedy or relief that a court of the state of California could 
order or grant within the scope hereof and such ancillary relief as is 
necessary to make effective any award, and (iii) shall have the power to 
award recovery of all costs and fees, to impose sanctions and to take such 
other actions as they deem necessary to the same extent a judge could 
pursuant to the Federal Rules of Civil Procedure, the California Rules of 
Civil Procedure or other applicable law.  Any Dispute in which the amount in 
controversy is $5,000,000 or less shall be decided by a single arbitrator who 
shall not render an award of greater than $5,000,000 (including damages, 
costs, fees



Cholestech Corporation
November 19, 1996
Page 12



and expenses).  By submission to a single arbitrator, each party expressly 
waives any right or claim to recover more than $5,000,000.  Any Dispute in 
which the amount in controversy exceeds $5,000,000 shall be decided by 
majority vote of a panel of three arbitrators; provided however, that all 
three arbitrators must actively participate in all hearings and deliberations.

     (e)  JUDICIAL REVIEW.  Notwithstanding anything herein to the contrary, 
in any arbitration in which the amount in controversy exceeds $25,000,000, 
the arbitrators shall be required to make specific, written findings of fact 
and conclusions of law. In such arbitrations (i) the arbitrators shall not 
have the power to make any award which is not supported by substantial 
evidence or which is based on legal error, (ii) an award shall not be binding 
upon the parties unless the findings of fact are supported by substantial 
evidence and the conclusions of law are not erroneous under the substantive 
law of the state of California, and (iii) the parties shall have in addition 
to the grounds referred to in the Federal Arbitration Act for vacating, 
modifying or correcting an award the right to judicial review of (A) whether 
the findings of fact rendered by the arbitrators are supported by substantial 
evidence, and (B) whether the conclusions of law are erroneous under the 
substantive law of the state of California.  Judgment confirming an award in 
such a proceeding may be entered only if a court determines the award is 
supported by substantial evidence and not based on legal error under the 
substantive law of the state of California.

     (f)  REAL PROPERTY COLLATERAL; JUDICIAL REFERENCE. Notwithstanding 
anything herein to the contrary, no Dispute shall be submitted to arbitration 
if the Dispute concerns indebtedness secured directly or indirectly, in whole 
or in part, by any real property unless (i) the holder of the mortgage, lien 
or security interest specifically elects in writing to proceed with the 
arbitration, or (ii) all parties to the arbitration waive any rights or 
benefits that might accrue to them by virtue of the single action rule 
statute of California, thereby agreeing that all indebtedness and obligations 
of the parties, and all mortgages, liens and security interests securing such 
indebtedness and obligations, shall remain fully valid and enforceable.  If 
any such Dispute is not submitted to arbitration, the Dispute shall be 
referred to a referee in accordance with California Code of Civil Procedure 
Section 638 et seq., and this general reference agreement is intended to be 
specifically enforceable in accordance with said Section 638. A referee with 
the qualifications required herein for arbitrators shall be selected pursuant 
to the AAA's selection procedures.



Cholestech Corporation
November 19, 1996
Page 13



Judgment upon the decision rendered by a referee shall be entered in the 
court in which such proceeding was commenced in accordance with California 
Code of Civil Procedure Sections 644 and 645.

     (g)  MISCELLANEOUS.  To the maximum extent practicable, the AAA, the 
arbitrators and the parties shall take all action required to conclude any 
arbitration proceeding within 180 days of the filing of the Dispute with the 
AAA.  No arbitrator or other party to an arbitration proceeding may disclose 
the existence, content or results thereof, except for disclosures of 
information by a party required in the ordinary course of its business, by 
applicable law or regulation, or to the extent necessary to exercise any 
judicial review rights set forth herein.  If more than one agreement for 
arbitration by or between the parties potentially applies to a Dispute, the 
arbitration provision most directly related to the Loan Documents or the 
subject matter of the Dispute shall control.  This arbitration provision 
shall survive termination, amendment or expiration of any of the Loan 
Documents or any relationship between the parties.

     Your acknowledgment of this letter shall constitute acceptance of the 
foregoing terms and conditions.  Bank's commitment to extend any credit to 
Borrower pursuant to the terms of this letter shall terminate on December 16, 
1996, unless this letter is acknowledged by Borrower and returned to Bank on 
or before that date.
