    This Amendment No. 5 (The "Amendment") dated as of April 10, 2000, is
between Bank of America, N.A. (the "Bank"), formerly Bank of America National
Trust and Savings Association, and Tab Products Co. (the "Borrower").

                                   RECITALS

    A.  The Bank and the Borrower entered into a certain Business Loan
Agreement dated as of November 1, 1998, as previously amended
(the "Agreement").

    B.  The Bank and the Borrower desire to further amend the Agreement.

                                   AGREEMENT

    1.  DEFINITIONS. Capitalized terms used but not defined in this Amendment
shall have the meaning given to them in the Agreement.

    2.  AMENDMENTS. The Agreement is hereby amended as follows:

        2.1  The Bank has changed the name of the "Reference Rate" to the
             "Prime Rate." The term "Reference Rate" is therefore amended to
             read "Prime Rate" throughout the Agreement.

        2.2  In Paragraph 1.1 of the Agreement, the amount "Five Million
             Dollars ($5,000,000)" is substituted for the amount "Fifteen
             Million Dollars ($15,000,000)."

        2.3  Paragraph 9.2(b) of the Agreement is amended to read in its
             entirety as follows:

             "(b)  Within 20 days of the period's end (including the last
                   period in each fiscal year), the Borrower's monthly
                   financial statements. These financial statements may be
                   Borrower prepared. The statements shall be prepared on a
                   consolidated and consolidating basis."

        2.4  Paragraph 9.3 of the Agreement is amended to read in its
             entirety as follows:

             "9.3  QUICK RATIO. To maintain on a consolidated basis as of the
                   end of each monthly accounting period a ratio of quick
                   assets to current liabilities of at least 1.40:1.0.

                   'Quick assets' means unencumbered cash, unencumbered
                   short-term cash investments, net trade receivables and
                   marketable securities not classified as long-term
                   investments. 'Current liabilities' shall include (a) all
                   obligations classified as current liabilities under
                   generally accepted accounting principles, plus (b) all
                   principal amounts outstanding under revolving lines of
                   credit, whether classified as current or long-term, which
                   are not already included under (a) above. The sum of
                   unencumbered cash and unencumbered short-term cash
                   investments must at all times equal at least Seven Million
                   Dollars ($7,000,000)."

        2.5  Paragraph 9.4 of the Agreement is amended to read in its
             entirety as follows:

             "9.4  NET WORTH. To maintain on a consolidated basis as of the
                   end of each monthly accounting period net worth equal to
                   at least the sum of the following:

             (a)   Fifty Two Million Dollars ($52,000,000); plus

             (b)   the net proceeds from any equity securities issued after
                   February 29, 2000.

                   'Net worth' means the gross book value of the Borrower's
                   assets less total liabilities, including but not limited
                   to accrued and deferred income taxes, and any reserves
                   against assets."

        2.6  Paragraphs 9.5 and 9.6 of the Agreement are deleted in their
             entirety.

        2.7  Paragraph 9.7 of the Agreement is amended to read in its
             entirety as follows:

                                      -1-

<PAGE>

             "9.7  LIMITATIONS ON LOSSES. Not to incur on a consolidated
                   basis a net loss after taxes in excess of Seven Hundred
                   Fifty Thousand Dollars ($750,000) in the fiscal quarter
                   ending May 31, 2000. Commencing with the quarterly
                   accounting period ending August 31, 2000, and thereafter,
                   the Borrower agrees not to incur on a consolidated basis a
                   net loss before taxes and extraordinary items in any two
                   (2) consecutive quarterly accounting periods. The Bank and
                   the Borrower acknowledge and agree that the calculation of
                   compliance with this covenant as of the last day of the
                   fiscal quarter ending August 31, 2000, shall include the
                   results of the fiscal quarter ending May 31, 2000."

        2.8  Paragraph 9.8(g) of the Agreement is deleted in its entirety.

        2.9  Paragraph 9.10 of the Agreement is amended to read in its
             entirety as follows:

             "9.10 CAPITAL EXPENDITURES. Not to spend (including the amount
                   of any capital leases) more than (i) Seven Hundred Fifty
                   Thousand Dollars ($750,000) in any single fiscal quarter
                   or (ii) Two Million Dollars ($2,000,000) in any single
                   fiscal year to acquire fixed or capital assets."

        2.10 The introductory paragraph of Article 11 of the Agreement is
             amended to read in its entirety as follows:

                   "If any of the following events occurs, the Bank may do
                   one or more of the following:  declare the Borrower in
                   default, stop making any additional credit available to the
                   Borrower, and require the Borrower to repay its entire
                   debt immediately and without prior notice. If an event of
                   default occurs under the paragraph entitled 'Bankruptcy,'
                   below, with respect to the Borrower, then the entire debt
                   outstanding under this Agreement will automatically be due
                   immediately."

representations and warranties in the Agreement are true as of the date of
this Amendment as if made on the date of this Amendment, (c) this Amendment is
within the Borrower's powers, has been duly authorized, and does not conflict
with any of the Borrower's organizational papers, and (d) this Amendment does
not conflict with any law, agreement, or obligation by which the Borrower is

                        CONFIDENTIAL RETIREMENT AGREEMENT
                          AND GENERAL RELEASE OF CLAIMS

         1. This Agreement is between Philip C. Kantz ("Employee") and TAB
Products Co., and shall be effective on the eighth day following its execution
by Employee (the "Effective Date"). Employee was employed by TAB Products Co.
(the "Company") on or about January 27, 1997. Employee was employed pursuant to
an Employment Agreement dated as of January 27, 1997, as amended by an Addendum
to Employment Agreement (collectively, the Employment Agreement and the Addendum
to Employment Agreement are hereinafter referred to as the "Employment
Agreement"). Employee has now decided to retire from his employment with the
Company.

         2. Employee hereby resigns from his employment with the Company
effective as of July 11, 2000 (the "Resignation Date"). Employee also hereby
resigns from his positions as an officer and director of the Company and from
all positions he holds as an officer and director of any Company subsidiary, as
of the Resignation Date.

         3. The Company shall provide Employee with:

            (a) the severance payments and benefits described in section 5(b)
of Employee's Employment Agreement (including an amount equal to two years'
pay at Employee's final base salary rate, an amount equal to two years' of
Employee's target bonus at the target bonus rate, which payments shall be
paid in a lump sum within five business days following the Effective Date; and

            (b) in the event that, prior to the two year anniversary of the
Effective Date: (a) Employee has not obtained alternative health insurance;
and (b) Employee's eligibility to continue to participate in the Company's
group health insurance policy under COBRA has expired, then the Company will
obtain alternative health insurance for Employee at the Company's expense,
such coverage to remain in effect until the two year anniversary of the
Effective Date.

Employee when this Agreement becomes effective. Subject to the foregoing
sentence, Employee acknowledges and agrees that he has been paid all wages and
accrued, unused vacation that Employee earned during his employment with the
Company. Employee understands and acknowledges that he shall not be entitled to
any payments or benefits from the Company other than those expressly set forth
in the first sentence of this paragraph.

         4. Employee and his successors release the Company and its
shareholders, investors, directors, officers, employees, agents, attorneys,
legal successors and assigns of and from any and all claims, actions and causes
of action, whether now known or unknown, which Employee now has, or at any other
time had, or shall or may have against the released parties based upon or
arising out of any matter, cause, fact, thing, act or omission whatsoever
occurring or existing at any time up to and including the Effective Date,
including, but not limited to, any claims of breach of contract, wrongful
termination, fraud, defamation, infliction of emotional distress or national
origin, race, age, sex, sexual orientation, disability or other discrimination
or harassment under the Civil Rights

<PAGE>

Act of 1964, the Age Discrimination In Employment Act of 1967, the Americans
With Disabilities Act, the Fair Employment and Housing Act or any other
applicable law.

         5. Employee acknowledges that he has read section 1542 of the Civil
Code of the State of California, which states in full:

                  A general release does not extend to claims which the creditor
                  does not know or suspect to exist in his favor at the time of
                  executing the release, which if known by him must have
                  materially affected his settlement with the debtor.

Employee waives any rights that he has or may have under section 1542 to the
full extent that he may lawfully waive such rights pertaining to this general
release of claims, and affirms that he is releasing all known and unknown claims
that he has or may have against the parties listed above.

         6. Employee acknowledges and agrees that he shall continue to be bound
by and comply with the terms of any proprietary rights or confidentiality
agreements between the Company and Employee.

         7. Employee agrees that for a period of 12 months following the
Resignation Date, he will not, on behalf of himself or any other person or
entity, directly or indirectly solicit any employee of the Company to terminate
his or her employment with the Company.

         8. This Agreement constitutes the entire agreement between the parties
with respect to the subject matter hereof and supersedes all prior negotiations
and agreements, whether written or oral, with the exception of any agreements
described in paragraph 6. This Agreement may not be modified or amended except
by a document signed by an authorized officer of the Company and Employee.

EMPLOYEE UNDERSTANDS THAT HE SHOULD CONSULT WITH AN ATTORNEY PRIOR TO SIGNING
THIS AGREEMENT AND THAT HE IS GIVING UP ANY LEGAL CLAIMS HE HAS AGAINST THE
PARTIES RELEASED ABOVE BY SIGNING THIS AGREEMENT. EMPLOYEE FURTHER UNDERSTANDS
THAT HE MAY HAVE UP TO 21 DAYS TO CONSIDER THIS AGREEMENT, THAT HE MAY REVOKE IT
AT ANY TIME DURING THE 7 DAYS AFTER HE SIGNS IT, AND THAT IT SHALL NOT BECOME
EFFECTIVE UNTIL THAT 7-DAY PERIOD HAS PASSED. EMPLOYEE ACKNOWLEDGES THAT HE IS
SIGNING THIS AGREEMENT KNOWINGLY, WILLINGLY AND VOLUNTARILY IN EXCHANGE FOR THE
SEVERANCE BENEFITS DESCRIBED IN PARAGRAPH 3.
