               HOME OFFICE REFERENCE LABORATORY, INC.
               STOCK PLAN FOR NON-EMPLOYEE DIRECTORS


          1.  Purpose.

          The purpose of the Home Office Reference Laboratory, Inc. Stock Plan 
for Non-Employee Directors (the "Plan") is to provide eligible Directors of 
Home Office Reference Laboratory, Inc. ("HORL") with an additional proprietary 
interest in HORL's success and progress by granting them a portion of their 
annual retainer fees in shares of HORL common stock ("Shares").

          2.  Administration.

          The Plan shall be administered, construed and interpreted by a 
committee (the "Committee") which shall consist of not less than three members 
of the Board of Directors of HORL who are not eligible to receive grants under 
Section 4 of the Plan.

          3.  Shares Subject to the Plan.

          The total number of Shares which may be granted under the Plan shall 
not exceed 100,000 shares, subject, however, to adjustment as provided in 
Section 7 hereof.  The Shares granted under the Plan may be either authorized 
but unissued Shares or treasury Shares.

          4.  Eligibility.

          All members of the Board of Directors of HORL who are not employees 
of HORL or any of its subsidiaries or affiliates shall be eligible to 
participate in the Plan (the "Eligible Directors").  Such persons shall cease 
to be Eligible Directors at the time that their membership on the Board of 
Directors of HORL terminates.

          5.  Compensation for Services.

          Each person who is an Eligible Director of HORL shall receive as 
compensation for his services $500 for each meeting of the Board of Directors 
and Committee of the Board of Directors attended, plus reimbursement for 
reasonable expenses incurred in attending such meetings.  Each person who is an
Eligible Director of HORL on the first business day of June of each year shall 
also receive as compensation for his services an annual retainer fee of (a) 
$5,000 in cash and (b) a grant of a number of Shares having a value equal to 
$10,000, based upon the average of the closing prices of the Shares on the last
five business days of May of each year.  Each Director appointed by the Board 
of Directors to fill a vacancy or a newly created directorship resulting from 
any increase in the authorized number of Directors as of any date other than 
the date of the annual meeting of the stockholders of HORL shall receive a 
proportionate share of the foregoing cash payment of $5,000 and a proportionate
grant of a number of Shares having a value equal to $10,000, based upon the 
average of the closing prices of the Shares on the last five business days of 
the month of his appointment as a Director of HORL, which shall be determined 
by multiplying such amounts by a fraction (i) the numerator of which shall be 
the number of full or partial months such Director is scheduled to be serve 
between the date of his election as a Director and the month during which the 
next succeeding annual meeting of the stockholders of HORL is scheduled to be 
held, and (ii) the denominator of which shall be twelve.  Any fractional share 
which may be issuable pursuant to this Section 5 shall be rounded to the 
nearest whole share.

          6.  General Restrictions.

          Each grant of Shares under the Plan shall be subject to the 
requirement that if at any time HORL shall determine that (a) the listing, 
registration or qualification of the Shares upon any securities exchange or 
under any state or federal law, or (b) the consent or approval of any 
regulatory body, or (c) any agreement by the recipient of a grant with respect 
to the disposition of the Shares, is necessary or desirable as a condition of 
or in connection with such grant of Shares, such grant shall not be made until 
such listing, registration, qualification, consent, approval, or agreement 
shall have been effected or obtained free of any conditions not acceptable to 
HORL.  Neither HORL nor its directors or officers nor the Committee shall have 
any obligation or liability to any Eligible Director with respect to which the 
grant or issuance of such Shares shall not be effected because of any such 
restriction.

          7.  Adjustments.

          In the event of a recapitalization, stock split, stock dividend, 
combination or exchange of Shares, merger, consolidation, rights offering, 
separation, reorganization or liquidation, or any other similar change in the 
corporate structure of HORL or the Shares, the Committee may make such 
equitable adjustments to prevent dilution or enlargement of rights in the 
number and class of Shares authorized to be granted hereunder as the Committee 
in its absolute discretion may deem appropriate.

          8.  Amendment of the Plan.

          The Board of Directors may terminate, amend, modify or suspend the 
Plan at any time, provided that the Board may not, without the approval of a 
majority of the outstanding Shares of HORL, increase the total number of Shares
which may be granted under the Plan or the number of Shares which may be 
granted to any Eligible Director (other than increases pursuant to Section 7 
hereof), or change the requirements as to eligibility for participation in the 
Plan.  The provisions of the Plan that   determine the eligibility requirements
for participation and the amount, price and timing of grants of Shares shall 
not be amended more than once every six months, other than to comport with 
changes in the Internal Revenue Code of 1986, as amended (the "Code"), the 
Employee Retirement Income Security Act ("ERISA"), or the rules promulgated 
thereunder.

          9.  Miscellaneous.

          (a)  Nothing in the Plan shall be deemed to create any obligation on 
the part of the Board of Directors to nominate any Director for reelection by 
the stockholders of HORL.

          (b)  Until the issuance of stock certificates, no right to vote or 
receive dividends or any other right as a shareholder of HORL shall exist with 
respect to the grant of Shares pursuant to the Plan.

          (c)  None of the benefits under the Plan are subject to the claims of
creditors of Eligible Directors or their beneficiaries, nor are they subject to
attachment, garnishment or any other legal process.  Neither an Eligible 
Director nor such Eligible Director's beneficiaries may assign, sell, transfer,
borrow on or otherwise encumber any beneficial interest in the Plan, other than
transfers by will or the laws of descent and distribution, or pursuant to a 
qualified domestic relations order, as defined by the Code, ERISA or the rules 
promulgated thereunder.

          (d)  For purposes of this Plan, a "subsidiary" means any person or 
organization more than 50% of whose outstanding voting securities is owned by 
HORL, and an "affiliate" means any person or organization that directly or 
indirectly through one or more intermediaries controls, or is controlled by, or
is under common control with, HORL.

          10.  Effective Date.

          The Plan shall become effective upon adoption by the Board of 
Directors of HORL, subject to the approval by the holders of a majority of the 
outstanding Shares at the 1992 annual meeting of the stockholders of HORL.
