         2.01     COMMITTED LOANS.

         (a)      Subject to the terms and conditions set forth herein, each
Lender severally agrees to make Domestic Loans to the Company from time to time,
on any Business Day during the Availability Period, in an aggregate amount not

provided, however, that after giving effect to any Borrowing, (i) the Total

Outstanding Amount of the Committed Loans of any Lender, plus such Lender's Pro
Rata Share of the Outstanding Amount of all L/C Obligations and all Bankers'
Acceptances (taking into account any Canadian Participations when determining
the Total Canadian Outstandings of a Canadian Lender) shall not exceed such
Lender's Commitment. Within the limits of each Lender's Commitment, and subject
to the other terms and conditions hereof, the Company may borrow under this
Section 2.01(a), prepay under Section 2.05, and reborrow under this Section
2.01(a). Domestic Loans may be Base Rate Loans or Eurodollar Rate Loans, as
further provided herein.

                  (b)(i) Subject to the terms and conditions set forth herein,
         each Canadian Lender severally agrees to make Canadian Loans to
         McKesson Canada from time to time, on any Business Day during the
         Availability Period, in an aggregate amount not to exceed at any time
         outstanding the amount of such Lender's Canadian Commitment; provided,
         however, that after giving effect to any Borrowing under the Canadian
         Commitments, (A) the Total Outstandings shall not exceed the Aggregate
         Commitments, (B) the Total Canadian Outstandings shall not exceed the
         Aggregate Canadian Commitments, (C) McKesson Canada shall be a
         Wholly-Owned Subsidiary, (D) the aggregate Outstanding Amount of the
         Canadian Loans of any Canadian Lender, plus such Lender's Pro Rata
         Share of the Acceptance Usage (taking into account any Canadian
         Participations when determining the Total Canadian Outstandings of a
         Canadian Lender) shall not exceed its Canadian Commitment, and (E) all
         Canadian Loans to McKesson Canada shall be made by the Canadian
         Lenders, shall be denominated and payable in Canadian Dollars and no

                                       22

<PAGE>

         other currency and shall not be Base Rate Loans. Within the limits of
         each Lender's Canadian Commitment, and subject to the other terms and
         conditions hereof, McKesson Canada may borrow under this Section
         2.01(b)(i), prepay under Section 2.05 and reborrow under this Section
         2.01(b)(i). Canadian Loans may be Canadian Prime Rate Loans or
         Eurodollar Rate Loans, as provided herein.

                           (ii)(A) Subject to Section 2.01(b)(ii)(B) below, on
                  the Participation Funding Date (as defined below) each Lender
                  that is not a Canadian Lender shall be deemed to have
                  purchased, and hereby agrees to purchase, a participation in
                  each outstanding Canadian Loan and Bankers' Acceptance Credit
                  Extension in an amount equal to its Pro Rata Share of the
                  unpaid amount of such Canadian Loan or Bankers' Acceptance
                  Credit Extension together with accrued interest thereon (each,
                  a "Canadian Participation"), such Canadian Participation to be
                  governed by this Section 2.01(b)(ii)(A) and not by Section
                  11.07(d) hereof. Only upon demand from any Canadian Lender on
                  or after the date of (X) any Event of Default under Sections
                  8.01(a), 8.01(f) or 8.01(g) or (Y) an acceleration of the
                  maturity pursuant to Section 8.02(b) of any amounts owing to
                  the Canadian Lenders under this Agreement (the date of such
                  demand, the "Participation Funding Date"), each such Lender
                  that has purchased a Canadian Participation (each a "Canadian
                  Participant") shall deliver to the Canadian Administrative
                  Agent an amount equal to its Canadian Participation in same
                  day funds and in Canadian Dollars at the Canadian
                  Administrative Agent's Office for distribution to Canadian
                  Lenders in accordance with their Canadian Pro Rata Share. If
                  any amount required to be paid by any Canadian Participant
                  pursuant to this Section 2.01(b)(ii)(A) is not paid to the
                  Canadian Administrative Agent when due but is paid within
                  three Business Days after the date such payment is due, such
                  Canadian Participant shall pay to the Canadian Administrative
                  Agent for distribution to Canadian Lenders on demand an amount
                  equal to the product of (i) such amount, times (ii) the
                  Overnight Canadian Rate, times (iii) a fraction the numerator
                  of which is the number of days that elapse during such period
                  and the denominator of which is 365 or 366, as the case may
                  be. If such amount required to be paid by any Canadian
                  Participant pursuant to this Section 2.01(b)(ii)(A) is not in
                  fact made available to the Canadian Administrative Agent
                  within three Business Days after the date such payment is due,
                  the Canadian Administrative Agent shall be entitled to recover
                  from such Canadian Participant, on demand, such amount with
                  interest thereon calculated from such due date at the rate per
                  annum equal to the rate applicable thereto in accordance with
                  the preceding sentence plus the Applicable Rate. A certificate
                  of the Canadian Administrative Agent submitted to any Canadian
                  Participant with respect to any amounts owing under this
                  Section 2.01(b)(ii)(A) shall be conclusive in the absence of
                  manifest error. In the event the Canadian Administrative Agent
                  receives a payment with respect to any Canadian Loan in which
                  Canadian Participations have been purchased and as to which
                  the purchase price has been requested by the Canadian
                  Administrative Agent and delivered by a Canadian Participant
                  as in this Section 2.01(b)(ii)(A) provided, the Canadian
                  Administrative Agent shall promptly distribute to such
                  Canadian Participant its share of such payment based on its
                  Canadian Participation. If the Canadian Administrative Agent
                  pays any amount

                                       23

<PAGE>

                  to a Canadian Participant pursuant to this Section
                  2.01(b)(ii)(A) in the belief or expectation that a related
                  payment has been or will be received or collected and such
                  related payment is not received or collected by the Canadian
                  Administrative Agent, then such Canadian Participant will
                  promptly on demand by the Canadian Administrative Agent return
                  such amount to the Canadian Administrative Agent, together
                  with interest thereon at such rate as the Canadian
                  Administrative Agent shall determine to be customary between
                  banks for correction of errors. If the Canadian Administrative
                  Agent determines at any time that any amount received or
                  collected by the Canadian Administrative Agent pursuant to
                  this Agreement is to be returned to McKesson Canada under this
                  Agreement or paid to any other Person or entity pursuant to
                  any Debtor Relief Laws, any sharing clause in this Agreement,
                  or otherwise, then, notwithstanding any other provision of
                  this Agreement, the Canadian Administrative Agent shall not be
                  required to distribute any portion thereof to any Canadian
                  Participant, and each such Canadian Participant will promptly
                  on demand by the Canadian Administrative Agent repay any
                  portion that the Canadian Administrative Agent shall have
                  distributed to such Canadian Participant, together with
                  interest thereon at such rate, if any, as the Canadian
                  Administrative Agent shall pay to McKesson Canada or such
                  other Person or entity with respect thereto. If any amounts
                  returned to McKesson Canada or reimbursed by a Canadian
                  Participant pursuant to this Section 2.01(b)(ii)(A) are later
                  recovered by the Canadian Administrative Agent, the Canadian
                  Administrative Agent shall promptly pay to each Canadian
                  Participant a proportionate share based on such Canadian
                  Participant's Canadian Participation.

                           (B)      Notwithstanding any other provision of this
                  Agreement, each Lender agrees that, prior to the Participation
                  Funding Date, all amounts paid or credited by McKesson Canada
                  under this Agreement to a Canadian Lender shall be received by
                  such Canadian Lender (a) for its own benefit and account or
                  (b) as agent for or for the account of an Eligible Assignee
                  that is a Canadian Resident in respect of the Canadian Loans,
                  and not otherwise as agent for or on behalf of any other
                  Person.

         2.02     BORROWINGS, CONVERSIONS AND CONTINUATIONS OF COMMITTED LOANS.

         (a)      With respect to Domestic Loans, each Borrowing, each
conversion of Committed Loans from one Type to the other, and each continuation
of Eurodollar Rate Loans shall be made upon the Company's irrevocable notice to
the Administrative Agent, which may be given by telephone. Each such notice must
be received by the Administrative Agent not later than 9:00 a.m. (i) three
Business Days prior to the requested date of any Borrowing of, conversion to or
continuation of Eurodollar Rate Loans or of any conversion of Eurodollar Rate
Loans to Base Rate Committed Loans, and (ii) on the requested date of any
Borrowing of Base Rate Committed Loans. With respect to Canadian Loans, each
Borrowing, each conversion of Canadian Loans from one Type to the other and each
continuation of Eurodollar Rate Loans shall be made upon McKesson Canada's
irrevocable notice to the Canadian Administrative Agent, which may be given by
telephone. Each such notice must be received by the Canadian Administrative
Agent not later than 11:00 a.m., Eastern time, (i) three Business Days prior to
the requested date of any Borrowing of, conversion to or continuation of
Eurodollar Rate Loans or of any conversion of

                                       24

<PAGE>

Eurodollar Rate Loans to Canadian Prime Rate Loans, and (ii) one Business Day
prior to the requested date of any Borrowing of Canadian Prime Rate Loans. Each
telephonic notice by a Borrower pursuant to this Section 2.02(a) must be
confirmed promptly by delivery to the Applicable Agent of a written Committed
Loan Notice, appropriately completed and signed by a Responsible Officer of the
Applicable Borrower. Each Borrowing, conversion or continuation of Domestic
Loans shall be in a principal amount of $5,000,000 or a whole multiple of
$1,000,000 in excess thereof and, in the case of Canadian Loans, in an aggregate
minimum amount of Cdn.$5,000,000 or any whole multiple of Cdn.$1,000,000 in
excess thereof. Except as provided in Section 2.03(c) and 2.04(g), each
Committed Loan Notice (whether telephonic or written) shall specify (i) whether
the Applicable Borrower is requesting a Borrowing, a conversion of Committed
Loans from one Type to the other, or a continuation of Eurodollar Rate Loans,
(ii) the identity of the Borrower and the requested date of the Borrowing,
conversion or continuation, as the case may be (which shall be a Business Day),
(iii) the principal amount of Committed Loans to be borrowed, converted or
continued, (iv) the Type of Committed Loans to be borrowed or to which existing
Committed Loans are to be converted, (v) if applicable, the duration of the
Interest Period with respect thereto and (vi) the Applicable Currency. If the
Applicable Borrower fails to specify a Type of Committed Loan in a Committed
Loan Notice or if the Applicable Borrower fails to give a timely notice
requesting a conversion or continuation, then the applicable Committed Loans
shall be made as, or converted to, Base Rate Loans or Canadian Prime Rate Loans,
as appropriate. Any such automatic conversion to Base Rate Loans or Canadian
Prime Rate Loans shall be effective as of the last day of the Interest Period
then in effect with respect to the applicable Eurodollar Rate Loans. If the
Applicable Borrower requests a Borrowing of, conversion to, or continuation of
Eurodollar Rate Loans in any such Committed Loan Notice, but fails to specify an
Interest Period, they will be deemed to have specified an Interest Period of one
month.

         (b)      Following receipt of a Committed Loan Notice for Domestic
Loans, the Administrative Agent shall promptly notify each Lender of the amount
of its Pro Rata Share of the applicable Domestic Loans, and if no timely notice
of a conversion or continuation is provided by the Company, the Administrative
Agent shall notify each Lender of the details of any automatic conversion to
Base Rate Loans described in Section 2.02(a). Following receipt of a Committed
Loan Notice for Canadian Loans, the Canadian Administrative Agent shall promptly
notify each Canadian Lender of the amount of its Canadian Pro Rata Share of the
applicable Canadian Loans, and if no timely notice of a conversion or
continuation is provided by the Borrowers, the Canadian Administrative Agent
shall notify each Canadian Lender of the details of any automatic conversion to
Canadian Prime Rate Loans described in Section 2.02(a). In the case of a
Borrowing, each Lender shall make the amount of its Domestic Loan available to
the Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than 11:00 a.m., and each Canadian Lender will make the
amount of its Canadian Loan available to the Canadian Administrative Agent in
Canadian Dollars at the Canadian Administrative Agent's Office by 11:00 a.m.,
Eastern time, on the Business Day specified in the applicable Committed Loan
Notice. Upon satisfaction of the applicable conditions set forth in Section 4.02
(and, if such Borrowing is the initial Credit Extension, Section 4.01), the
Applicable Agent shall make all funds so received available to the Applicable
Borrower in like funds as received by the Applicable Agent either by (i)
crediting the account of the Applicable Borrower on the books of Bank of America
or BA Canada with the amount of such funds or (ii) wire transfer of such funds,
in each case in accordance with instructions provided to (and reasonably

                                       25

<PAGE>

acceptable to) the Applicable Agent by the Applicable Borrower; provided,
however, that if, on the date the Committed Loan Notice with respect to such
Borrowing is given by a Borrower, there are unpaid amounts due in respect of
Bankers' Acceptances, in the case of McKesson Canada, or L/C Borrowings
outstanding, in the case of the Company, then the proceeds of such Borrowing
shall be applied, first, to the payment in full of any such L/C Borrowings, and
second, to the Applicable Borrower as provided above.

         (c)      Except as otherwise provided herein, a Eurodollar Rate Loan
may be continued or converted only on the last day of an Interest Period for
such Eurodollar Rate Loan. During the existence of a Default, no Loans may be
requested as, converted to or continued as Eurodollar Rate Loans without the
consent of the Required Lenders.

         (d)      The Administrative Agent shall promptly notify the Applicable
Borrower and the Lenders of the interest rate applicable to any Interest Period
for Eurodollar Rate Loans upon determination of such interest rate. The
determination of the Eurodollar Rate by the Administrative Agent shall be
conclusive in the absence of manifest error. At any time that Base Rate Loans
are outstanding, the Administrative Agent shall notify the Company and the
Lenders of any change in Bank of America's prime rate used in determining the
Base Rate promptly following the public announcement of such change. At any time
that Canadian Prime Rate Loans are outstanding, the Canadian Administrative
Agent shall notify McKesson Canada and the Canadian Lenders of any change in BA
Canada's prime lending rate used in determining the Canadian Prime Rate promptly
following the public announcement of such change.

         (e)      After giving effect to all Borrowings, all conversions of
Committed Loans from one Type to the other, and all continuations of Committed
Loans as the same Type, there shall not be more than ten Interest Periods in
effect at any time with respect to Committed Loans.

         (f)      The Dollar Equivalent amount of any Borrowing in Canadian
Dollars will be determined by the Canadian Administrative Agent for such
Borrowing on the Computation Date therefor in accordance with Section 2.16(a)
and shall be conclusive absent manifest error.

         2.03     LETTERS OF CREDIT.

         (a)      The Letter of Credit Commitment.

                  (i)      Subject to the terms and conditions set forth herein,
         (A) the L/C Issuer agrees, in reliance upon the agreements of the other
         Lenders set forth in this Section 2.03, (1) from time to time on any
         Business Day during the period from the Closing Date until the Letter
         of Credit Expiration Date, to issue Letters of Credit for the account
         of the Company or certain Subsidiaries, and to amend or renew Letters
         of Credit previously issued by it, in accordance with Section 2.03(b),
         and (2) to honor drafts under the Letters of Credit; and (B) the
         Lenders severally agree to participate in Letters of Credit issued for
         the account of the Company; provided that the L/C Issuer shall not be
         obligated to make any L/C Credit Extension with respect to any Letter
         of Credit, and no Lender shall be obligated to participate in any
         Letter of Credit if as of the date of such L/C Credit Extension, (x)
         the Total Outstandings would exceed the Aggregate Commitments, (y) the
         aggregate Outstanding Amount of the Committed Loans of any Lender, plus
         such

                                       26

<PAGE>

         Lender's Pro Rata Share of the Outstanding Amount of all L/C
         Obligations, would exceed such Lender's Commitment, or (z) the
         Outstanding Amount of the L/C Obligations would exceed the Letter of
         Credit Sublimit. Within the foregoing limits, and subject to the terms
         and conditions hereof, the Company's ability to obtain Letters of
         Credit shall be fully revolving, and accordingly the Company may,
         during the foregoing period, obtain Letters of Credit to replace
         Letters of Credit that have expired or that have been drawn upon and
         reimbursed.

                  (ii)     The L/C Issuer shall be under no obligation to issue
         any Letter of Credit if:

                           (A)      any order, judgment or decree of any
                  Governmental Authority or arbitrator shall by its terms
                  purport to enjoin or restrain the L/C Issuer from issuing such
                  Letter of Credit, or any Law applicable to the L/C Issuer or
                  any request or directive (whether or not having the force of
                  law) from any Governmental Authority with jurisdiction over
                  the L/C Issuer shall prohibit, or request that the L/C Issuer
                  refrain from, the issuance of letters of credit generally or
                  such Letter of Credit in particular or shall impose upon the
                  L/C Issuer with respect to such Letter of Credit any
                  restriction, reserve or capital requirement (for which the L/C
                  Issuer is not otherwise compensated hereunder) not in effect
                  on the Closing Date, or shall impose upon the L/C Issuer any
                  unreimbursed loss, cost or expense which was not applicable on
                  the Closing Date and which the L/C Issuer in good faith deems
                  material to it;

                           (B)      subject to Section 2.03(b)(iii), the expiry
                  date of such requested Letter of Credit would occur more than
                  twelve months after the date of issuance or last renewal,
                  unless the Required Lenders have approved such expiry date;

                           (C)      the expiry date of such requested Letter of
                  Credit would occur after the Letter of Credit Expiration Date,
                  unless all the Lenders have approved such expiry date; or

                           (D)      such Letter of Credit is in an initial
                  amount less than $100,000, in the case of a commercial Letter
                  of Credit, or $500,000, in the case of a standby Letter of
                  Credit, or is to be denominated in a currency other than
                  Dollars; provided that the $500,000 minimum amount relating to
                  a standby Letter of Credit shall not be applicable if the
                  Company pays to the L/C Issuer in respect of such Letter of
                  Credit an additional issuance fee in an amount to be agreed
                  between the Company and the L/C Issuer from time to time.

                  (iii)    The L/C Issuer shall be under no obligation to amend
         any Letter of Credit if (A) the L/C Issuer would have no obligation at
         such time to issue such Letter of Credit in its amended form under the
         terms hereof, or (B) the Beneficiary of such Letter of Credit does not
         accept the proposed amendment to such Letter of Credit.

                  (iv)     On and after the Closing Date, the Existing Letters
         of Credit shall be deemed for all purposes, including for purposes of
         the fees and charges to be collected pursuant to this Section 2.03 for
         periods on and after the Closing Date, and

                                       27

<PAGE>

         reimbursement of costs and expenses to the extent provided herein, to
         be Letters of Credit outstanding under this Agreement and entitled to
         the benefits of this Agreement and the other Loan Documents, and shall
         be governed by the applications and agreements pertaining thereto and
         by this Agreement; provided, however, that, notwithstanding any other
         provision of this Agreement, no fees with respect to the initial
         issuance of the Existing Letters of Credit shall be due hereunder.

         (b)      Procedures for Issuance and Amendment of Letters of Credit;
Auto-Renewal Letters of Credit.

                  (i)      Each Letter of Credit shall be issued or amended, as
         the case may be, upon the request of the Company delivered to the L/C
         Issuer (with a copy to the Administrative Agent) in the form of a
         Letter of Credit Application, appropriately completed and signed by a
         Responsible Officer of the Company. Such Letter of Credit Application
         must be received by the L/C Issuer and the Administrative Agent not
         later than 9:00 a.m. at least three Business Days (or such later date
         and time as the L/C Issuer may agree in a particular instance in its
         sole discretion) prior to the proposed issuance date or date of
         amendment, as the case may be. In the case of a request for an initial
         issuance of a Letter of Credit, such Letter of Credit Application shall
         specify in form and detail satisfactory to the L/C Issuer: (A) the
         proposed issuance date of the requested Letter of Credit (which shall
         be a Business Day); (B) the amount thereof; (C) the expiry date
         thereof; (D) the name and address of the beneficiary thereof; (E) the
         documents to be presented by the Beneficiary in case of any drawing
         thereunder; (F) the full text of any certificate to be presented by the
         Beneficiary in case of any drawing thereunder; and (G) such other
         matters as the L/C Issuer may require. In the case of a request for an
         amendment of any outstanding Letter of Credit, such Letter of Credit
         Application shall specify in form and detail satisfactory to the L/C
         Issuer (A) the Letter of Credit to be amended; (B) the proposed date of
         amendment thereof (which shall be a Business Day); (C) the nature of
         the proposed amendment; and (D) such other matters as the L/C Issuer
         may require.

                  (ii)     Promptly after receipt of any Letter of Credit
         Application, the L/C Issuer will confirm with the Administrative Agent
         (by telephone or in writing) that the Administrative Agent has received
         a copy of such Letter of Credit Application from the Company and, if
         not, the L/C Issuer will provide the Administrative Agent with a copy
         thereof. Upon receipt by the L/C Issuer of confirmation from the
         Administrative Agent that the requested issuance or amendment is
         permitted in accordance with the terms hereof, then, subject to the
         terms and conditions hereof, the L/C Issuer shall, on the requested
         date, issue a Letter of Credit for the account of the Company or enter
         into the applicable amendment, as the case may be, in each case in
         accordance with the L/C Issuer's usual and customary business
         practices. Immediately upon the issuance of each Letter of Credit, each
         Lender shall be deemed to, and hereby irrevocably and unconditionally
         agrees to, purchase from the L/C Issuer a risk participation in such
         Letter of Credit in an amount equal to the product of such Lender's Pro
         Rata Share times the amount of such Letter of Credit.

                  (iii)    If the Company so requests in any applicable Letter
         of Credit Application, the L/C Issuer shall issue a Letter of Credit
         that has automatic renewal provisions (each,

                                       28

<PAGE>

         an "Auto-Renewal Letter of Credit"); provided that any such
         Auto-Renewal Letter of Credit must permit the L/C Issuer to prevent any
         such renewal at least once in each twelve-month period (commencing with
         the date of issuance of such Letter of Credit) by giving prior notice
         to the beneficiary thereof not later than a day (the "Nonrenewal Notice
         Date") in each such twelve-month period to be agreed upon at the time
         such Letter of Credit is issued; provided further that the L/C Issuer
         shall not exercise its right to prevent any such renewal unless the L/C
         Issuer determines that it would have no obligation at such time to
         issue such Letter of Credit in its renewed form under the terms of this
         Agreement. Unless otherwise directed by the L/C Issuer, the Company
         shall not be required to make a specific request to the L/C Issuer for
         any such renewal. Once an Auto-Renewal Letter of Credit has been
         issued, the Lenders shall be deemed to have authorized (but may not
         require) the L/C Issuer to permit the renewal of such Letter of Credit
         at any time to an expiry date not later than the Letter of Credit
         Expiration Date; provided, however, that the L/C Issuer shall not
         permit any such renewal if (A) the L/C Issuer has determined that it
         would have no obligation at such time to issue such Letter of Credit in
         its renewed form under the terms of this Agreement (by reason of the
         provisions of Section 2.03(a)(ii) or otherwise), or (B) it has received
         notice (which may be by telephone or in writing) on or before the day
         that is five Business Days before the Nonrenewal Notice Date from the
         Administrative Agent, any Lender or the Company that one or more of the
         applicable conditions specified in Section 4.02 is not then satisfied.

                  (iv)     Promptly after its delivery of any Letter of Credit
         or any amendment to a Letter of Credit to an advising bank with respect
         thereto or to the beneficiary thereof, the L/C Issuer will also deliver
         to the Company and the Administrative Agent a true and complete copy of
         such Letter of Credit or amendment.

         (c)      Drawings and Reimbursements; Funding of Participations.

                  (i)      Upon receipt from the Beneficiary of any Letter of
         Credit of any notice of a drawing under such Letter of Credit, the L/C
         Issuer shall notify the Company and the Administrative Agent thereof.
         Not later than 11:00 a.m. on the date of any payment by the L/C Issuer
         under a Letter of Credit (each such date, an "Honor Date"), the Company
         shall reimburse the L/C Issuer through the Administrative Agent in an
         amount equal to the amount of such drawing. If the Company fails to so
         reimburse the L/C Issuer by such time, the Administrative Agent shall
         promptly notify each Lender of the Honor Date, the amount of the
         unreimbursed drawing (the "Unreimbursed Amount"), and the amount of
         such Lender's Pro Rata Share thereof. In such event, the Company shall
         be deemed to have requested a Borrowing of Base Rate Loans to be
         disbursed on the Honor Date in an amount equal to the Unreimbursed
         Amount, without regard to the minimum and multiples specified in
         Section 2.02 for the principal amount of Base Rate Loans, but subject
         to the amount of the unutilized portion of the Aggregate Commitments
         and the conditions set forth in Section 4.02 (other than the delivery
         of a Committed Loan Notice). Any notice given by the L/C Issuer or the
         Administrative Agent pursuant to this Section 2.03(c)(i) may be given
         by telephone if immediately confirmed in writing; provided that the
         lack of such an immediate confirmation shall not affect the
         conclusiveness or binding effect of such notice.

                                       29

<PAGE>

                  (ii)     Each Lender (including the Lender acting as L/C
         Issuer) shall upon any notice pursuant to Section 2.03(c)(i) make funds
         available to the Administrative Agent for the account of the L/C Issuer
         at the Administrative Agent's Office in an amount equal to its Pro Rata
         Share of the Unreimbursed Amount not later than 1:00 p.m. on the
         Business Day specified in such notice by the Administrative Agent,
         whereupon, subject to the provisions of Section 2.03(c)(iii), each
         Lender that so makes funds available shall be deemed to have made a
         Base Rate Committed Loan to the Company in such amount. The
         Administrative Agent shall remit the funds so received to the L/C
         Issuer.

                  (iii)    With respect to any Unreimbursed Amount that is not
         fully refinanced by a Borrowing of Base Rate Loans because the
         conditions set forth in Section 4.02 cannot be satisfied or for any
         other reason, the Company shall be deemed to have incurred from the L/C
         Issuer an L/C Borrowing in the amount of the Unreimbursed Amount that
         is not so refinanced, which L/C Borrowing shall be due and payable on
         demand (together with interest) and shall bear interest at the Default
         Rate. In such event, each Lender's payment to the Administrative Agent
         for the account of the L/C Issuer pursuant to Section 2.03(c)(ii) shall
         be deemed payment in respect of its participation in such L/C Borrowing
         and shall constitute an L/C Advance from such Lender in satisfaction of
         its participation obligation under this Section 2.03.

                  (iv)     Until each Lender funds its Committed Loan or L/C
         Advance pursuant to this Section 2.03(c) to reimburse the L/C Issuer
         for any amount drawn under any Letter of Credit, interest in respect of
         such Lender's Pro Rata Share of such amount shall be solely for the
         account of the L/C Issuer.

                  (v)      Each Lender's obligation to make Committed Loans or
         L/C Advances to reimburse the L/C Issuer for amounts drawn under
         Letters of Credit, as contemplated by this Section 2.03(c), shall be
         absolute and unconditional and shall not be affected by any
         circumstance, including (A) any set-off, counterclaim, recoupment,
         defense or other right which such Lender may have against the L/C
         Issuer, the Company or any other Person for any reason whatsoever; (B)
         the occurrence or continuance of a Default, or (C) any other
         occurrence, event or condition, whether or not similar to any of the
         foregoing; provided, however, that each Lender's obligation to make
         Committed Loans pursuant to this Section 2.03(c) is subject to the
         conditions set forth in Section 4.02 (other than delivery by the
         Company of a Committed Loan Notice). No such making of an L/C Advance
         shall relieve or otherwise impair the obligation of the Company to
         reimburse the L/C Issuer for the amount of any payment made by the L/C
         Issuer under any Letter of Credit, together with interest as provided
         herein.

                  (vi)     If any Lender fails to make available to the
         Administrative Agent for the account of the L/C Issuer any amount
         required to be paid by such Lender pursuant to the foregoing provisions
         of this Section 2.03(c) by the time specified in Section 2.03(c)(ii),
         the L/C Issuer shall be entitled to recover from such Lender (acting
         through the Administrative Agent), on demand, such amount with interest
         thereon for the period from the date such payment is required to the
         date on which such payment is immediately available to the L/C Issuer
         at a rate per annum equal to the Federal Funds Rate from time to time
         in effect. A certificate of the L/C Issuer submitted to any Lender
         (through the

                                       30

<PAGE>

         Administrative Agent) with respect to any amounts owing under this
         clause (vi) shall be conclusive absent manifest error.

         (d)      Repayment of Participations.

                  (i)      At any time after the L/C Issuer has made a payment
         under any Letter of Credit and has received from any Lender such
         Lender's L/C Advance in respect of such payment in accordance with
         Section 2.03(c), if the Administrative Agent receives for the account
         of the L/C Issuer any payment in respect of the related Unreimbursed
         Amount or interest thereon (whether directly from the Company or
         otherwise, including proceeds of Cash Collateral applied thereto by the
         Administrative Agent), the Administrative Agent will distribute to such
         Lender its Pro Rata Share thereof (appropriately adjusted, in the case
         of interest payments, to reflect the period of time during which such
         Lender's L/C Advance was outstanding) in the same funds as those
         received by the Administrative Agent.

                  (ii)     If any payment received by the Administrative Agent
         for the account of the L/C Issuer pursuant to Section 2.03(c)(i) is
         required to be returned under any of the circumstances described in
         Section 11.06 (including pursuant to any settlement entered into by the
         L/C Issuer in its discretion), each Lender shall pay to the
         Administrative Agent for the account of the L/C Issuer its Pro Rata
         Share thereof on demand of the Administrative Agent, plus interest
         thereon from the date of such demand to the date such amount is
         returned by such Lender, at a rate per annum equal to the Federal Funds
         Rate from time to time in effect.

         (e)      Obligations Absolute. The obligation of the Company to
reimburse the L/C Issuer for each drawing under each Letter of Credit and to
repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and
shall be paid strictly in accordance with the terms of this Agreement under all
circumstances, including the following:

                  (i)      any lack of validity or enforceability of such Letter
         of Credit, this Agreement, or any other agreement or instrument
         relating thereto;

                  (ii)     the existence of any claim, counterclaim, set-off,
         defense or other right that the Company may have at any time against
         any Beneficiary of such Letter of Credit (or any Person for whom any
         such Beneficiary may be acting), the L/C Issuer or any other Person,
         whether in connection with this Agreement, the transactions
         contemplated hereby or by such Letter of Credit or any agreement or
         instrument relating thereto, or any unrelated transaction;

                  (iii)    any draft, demand, certificate or other document
         presented under such Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect; or any loss or delay in the
         transmission or otherwise of any document required in order to make a
         drawing under such Letter of Credit;

                  (iv)     any payment by the L/C Issuer under such Letter of
         Credit against presentation of a draft or certificate that does not
         strictly comply with the terms of such

                                       31

<PAGE>

         Letter of Credit; or any payment made by the L/C Issuer under such
         Letter of Credit to any Person purporting to be a trustee in
         bankruptcy, debtor-in-possession, assignee for the benefit of
         creditors, liquidator, receiver or other representative of any
         Beneficiary or of such Letter of Credit, including any arising in
         connection with any proceeding under any Debtor Relief Law; or

                  (v)      any other circumstance or happening whatsoever,
         whether or not similar to any of the foregoing, including any other
         circumstance that might otherwise constitute a defense available to, or
         a discharge of, the Company.

         The Company shall promptly examine a copy of each Letter of Credit and
each amendment thereto that is delivered to it and, in the event of any claim of
noncompliance with the Company's instructions or other irregularity, the Company
will immediately notify the L/C Issuer. The Company shall be conclusively deemed
to have waived any such claim against the L/C Issuer and its correspondents
unless such notice is given as aforesaid.

         (f)      Role of L/C Issuer. Each Lender and the Company agree that, in
paying any drawing under a Letter of Credit, the L/C Issuer shall not have any
responsibility to obtain any document (other than any sight draft, certificates
and documents expressly required by the Letter of Credit) or to ascertain or
inquire as to the validity or accuracy of any such document or the authority of
the Person executing or delivering any such document. None of the L/C Issuer,
any Agent-Related Person nor any of the respective correspondents, participants
or assignees of the L/C Issuer shall be liable to any Lender for (i) any action
taken or omitted in connection herewith at the request or with the approval of
the Lenders or the Required Lenders, as applicable; (ii) any action taken or
omitted in the absence of gross negligence or willful misconduct; or (iii) the
due execution, effectiveness, validity or enforceability of any document or
instrument related to any Letter of Credit or Letter of Credit Application. The
Company hereby assumes all risks of the acts or omissions of any Beneficiary
with respect to its use of any Letter of Credit; provided, however, that this
assumption is not intended to, and shall not, preclude the Company's pursuing
such rights and remedies as it may have against the Beneficiary at law or under
any other agreement. None of the L/C Issuer, any Agent-Related Person, nor any
of the respective correspondents, participants or assignees of the L/C Issuer,
shall be liable or responsible for any of the matters described in clauses (i)
through (v) of Section 2.03(e); provided, however, that anything in such clauses
to the contrary notwithstanding, the Company may have a claim against the L/C
Issuer, and the L/C Issuer may be liable to the Company, to the extent, but only
to the extent, of any direct, as opposed to consequential or exemplary, damages
suffered by the Company which the Company proves were caused by the L/C Issuer's
willful misconduct or gross negligence or the L/C Issuer's willful failure to
pay under any Letter of Credit after the presentation to it of a sight draft and
certificate(s) strictly complying with the terms and conditions of a Letter of
Credit. In furtherance and not in limitation of the foregoing, the L/C Issuer
may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary, and the L/C Issuer shall not be responsible for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

                                       32

         (g)      Cash Collateral. Upon the request of the Administrative Agent,
(i) if the L/C Issuer has honored any full or partial drawing request under any
Letter of Credit and such drawing has resulted in an L/C Borrowing, or (ii) if,
as of the Letter of Credit Expiration Date, any Letter of Credit may for any
reason remain outstanding and partially or wholly undrawn, the Company shall
immediately Cash Collateralize the then Outstanding Amount of all L/C
Obligations (in an amount equal to such Outstanding Amount determined as of the
date of such L/C Borrowing or the Letter of Credit Expiration Date, as the case
may be). For purposes hereof, "Cash Collateralize" means to pledge and deposit
with or deliver to the Administrative Agent, for the benefit of the L/C Issuer
and the Lenders, as collateral for the L/C Obligations, cash or deposit account
balances pursuant to documentation in form and substance satisfactory to the
Administrative Agent and the L/C Issuer (which documents are hereby consented to
by the Lenders). Derivatives of such term have corresponding meanings. The
Company hereby grants to the Administrative Agent, for the benefit of the L/C
Issuer and the Lenders, a security interest in all such cash, deposit accounts
and all balances therein and all proceeds of the foregoing. Cash collateral
shall be maintained in blocked, non-interest bearing deposit accounts at Bank of
America.

         (h)      Applicability of ISP 98 and UCP. Unless otherwise expressly
agreed by the L/C Issuer and the Company when a Letter of Credit is issued, (i)
the rules of the "International Standby Practices (ISP 98)" published by the
Institute of International Banking Law & Practice, Inc. (or such later version
thereof as may be in effect at the time of issuance), with the exception of Rule
5.09 thereof, shall apply to each standby Letter of Credit, and (ii) the rules
of the Uniform Customs and Practice for Documentary Credits, as most recently
published by the International Chamber of Commerce (the "ICC") at the time of

Technique and Practice on April 6, 1998 regarding the European single currency

         (i)      Letter of Credit Fees. The Company shall pay to the
Administrative Agent for the account of each Lender in accordance with its Pro
Rata Share a letter of credit fee for each Letter of Credit equal to the
Applicable Rate times the daily maximum amount available to be drawn under such
Letter of Credit (whether or not such maximum amount is then in effect under
such Letter of Credit). Such letter of credit fees shall be computed on a
quarterly basis in arrears. Such letter of credit fees shall be due and payable
on the fifth Business Day following the end of each calendar quarter, commencing
with the first such date to occur after the issuance of such Letter of Credit,
on the Letter of Credit Expiration Date and thereafter on demand. If there is
any change in the Applicable Rate during any quarter, the daily maximum amount
of each Letter of Credit shall be computed and multiplied by the Applicable Rate
separately for each period during such quarter that such Applicable Rate was in
effect.

         (j)      Fronting Fee and Documentary and Processing Charges Payable to
L/C Issuer. The Company shall pay directly to the L/C Issuer for its own account
a fronting fee with respect to each Letter of Credit in an amount equal to .125%
per annum times the daily maximum amount available to be drawn under such Letter
of Credit. Such fronting fees shall be computed on a quarterly basis in arrears.
Such fronting fees shall be due and payable on the first Business Day after the
end of each calendar quarter, commencing with the first such date to occur after
the issuance of such Letter of Credit, on the Letter of Credit Expiration Date
and thereafter on demand. In addition, the Company shall pay directly to the L/C
Issuer for its own account the

                                       33

customary issuance, presentation, amendment and other processing fees, and other
standard costs and charges, of the L/C Issuer relating to letters of credit as
from time to time in effect. Such customary fees and standard costs and charges
are due and payable on demand and are nonrefundable.

         (k)      Conflict with Letter of Credit Application. In the event of
any conflict between the terms hereof and the terms of any Letter of Credit
Application, the terms hereof shall control.

         (l)      Reports to Administrative Agent. The L/C Issuer shall deliver
to the Administrative Agent, upon each calendar month end, a report setting
forth for such period the daily aggregate amount available to be drawn under the
Letters of Credit that were outstanding during such month.

         2.04     BANKERS' ACCEPTANCES FOR MCKESSON CANADA.

         (a)      Acceptance Commitment.

                  (i)      Each Canadian Lender severally agrees, on and subject
         to the terms and conditions set forth herein: (A) in the case of a
         Canadian Lender that is able to accept Drafts from McKesson Canada, to
         create acceptances (each, a "Bankers' Acceptance") by accepting Drafts
         from McKesson Canada and to purchase such Bankers' Acceptances in
         accordance with Section 2.04(d); and (B) in the case of a Canadian
         Lender that has participated all or any part of its interest in the
         Bankers' Acceptance Facilities to a participant that is able to accept
         Drafts from McKesson Canada, to arrange for the creation of Bankers'
         Acceptances by such participant and for the purchase of such Bankers'
         Acceptances by such participant, to the extent of such participation or
         assignment, in accordance with Section 2.04(d).

                  (ii)     Each Drawing shall be in an aggregate Face Amount of
         not less than Cdn.$5,000,000 and in integral multiples of
         Cdn.$1,000,000 and shall consist of the creation and purchase of
         Bankers' Acceptances on the same day, effected or arranged by the
         Canadian Lenders in accordance with Section 2.04(d), ratably according
         to their respective Canadian Pro Rata Shares.

                  (iii)    Anything contained in this Agreement to the contrary
         notwithstanding, the Bankers' Acceptance Facility and the Canadian
         Commitments shall be subject to the following limitations:

                           (A)      the amount otherwise available for Drawing
                  under the Aggregate Canadian Commitment as of any time of
                  determination shall be reduced by an amount equal to the Total
                  Canadian Outstandings as of such time of determination;

                           (B)      after any Drawing the Total Outstandings
                  shall not exceed the Aggregate Commitments then in effect; and

                           (C)      after any Drawing the Total Canadian
                  Outstandings shall not exceed the Aggregate Canadian
                  Commitments then in effect.

                                       34

<PAGE>

         (b)      Drawing Notice.

                  (i)      Each Drawing shall be made on three Business Days'
         prior written notice specified in relation to Bankers' Acceptances,
         given not later than 11:00 a.m. (Toronto time), by McKesson Canada to
         the Canadian Administrative Agent. Each such notice of a Drawing (a
         "Drawing Notice") shall be given in substantially the form of Exhibit F
         annexed hereto or by telephone confirmed promptly in writing,
         containing the same information as would be contained in a Drawing
         Notice, and shall specify therein (A) the Drawing Date; (B) the
         aggregate Face Amount of Drafts to be accepted; and (C) the maturity
         date for such Drafts. The Canadian Administrative Agent shall give each
         Canadian Lender prompt notice of such Drawing Notice and of such
         Canadian Lender's ratable portion of Drafts to be accepted under the
         Drawing.

                  (ii)     McKesson Canada shall not request in a Drawing Notice
         a maturity date for Drafts that would be subsequent to the Maturity
         Date.

                  (iii)    Each Drawing Notice shall be irrevocable and binding
         on McKesson Canada. McKesson Canada shall indemnify each Canadian
         Lender against any loss or expense incurred by such Canadian Lender as
         a result of any failure by McKesson Canada to fulfill or honor before
         the date specified for any Drawing, the applicable conditions set forth
         in this Section 2.04 or Section 4.02, if the Drawing, as a result of
         such failure, is not made on such date.

                  (iv)     McKesson Canada shall repay, and there shall become
         due and payable, on the Drawing Date the principal amount of any
         Canadian Loans which McKesson Canada seeks to convert, if any, in whole
         or in part, to Bankers' Acceptances on such Drawing Date.

                  (v)      None of the Canadian Administrative Agent, the
         Administrative Agent or the Canadian Lenders shall incur any liability
         to McKesson Canada or the Company in acting on the telephonic notice
         referred to above which the Canadian Administrative Agent, the
         Administrative Agent or any Canadian Lenders believes in good faith to
         have been given by a duly authorized officer or other person authorized
         to borrow on behalf of McKesson Canada or for otherwise acting in good
         faith under this Section 2.04 and upon the acceptance of Drafts
         pursuant to any such telephonic notice, McKesson Canada shall be liable
         with respect thereto as provided herein. In the event of a conflict
         between the Canadian Administrative Agent's record of the applicable
         terms of any Drawing and such Drawing Notice, the Canadian
         Administrative Agent's record shall prevail, absent manifest or
         demonstrable error.

         (c)      Form of Bankers' Acceptances.

                  (i)      Each Draft presented by McKesson Canada shall (A) be
         dated the date of the Drawing; (B) mature and be payable by McKesson
         Canada (in common with all other Drafts presented in connection with
         such Drawing) on a Business Day which occurs no less than 30 days nor
         more than 180 days after the date thereof, which term shall be
         specified on the Drawing Notice presented by McKesson Canada in
         accordance with

                                       35

<PAGE>

         Section 2.04(b)(1); (C) be in a form reasonably acceptable to the
         Canadian Administrative Agent; and (D) if such Draft is drawn on a
         Canadian Lender that is a Member, be payable to the Clearing House.

                  (ii)     McKesson Canada hereby renounces, and shall not
         claim, any days of grace for the payment of any Bankers' Acceptances.

         (d)      Acceptance and Purchase of Drafts.

                  (i)      Not later than 11:00 a.m. (Toronto time) on an
         applicable Drawing Date, each Canadian Lender shall, as the case may
         be, (A) complete one or more Drafts dated the date of such Drawing,
         with the maturity date specified by McKesson Canada in the Drawing
         Notice, accept such Drafts, and purchase the Bankers' Acceptances
         thereby created for the Drawing Purchase Price; and (B) arrange for its
         participant to complete one or more Drafts dated the date of such
         Drawing, with the maturity date specified by McKesson Canada in the
         Drawing Notice, to accept such Drafts and to purchase the Bankers'
         Acceptances thereby created for the Drawing Purchase Price.

                  (ii)     The failure of any Canadian Lender to accept Drafts
         or purchase Bankers' Acceptances as part of any Drawing shall not
         relieve such Canadian Lender of its obligation, if any, to accept
         Drafts and purchase Bankers' Acceptances hereunder, but a Canadian
         Lender shall not be responsible for the failure of any other Canadian
         Lender to accept Drafts or purchase Bankers' Acceptance on the Drawing
         Date for any Drawing.

                  (iii)    The parties hereto agree that in the administering of
         Bankers' Acceptances, each Canadian Lender may avail itself of the debt
         clearing services offered by the Clearing House and that the procedures
         set forth in Section 2.04 be deemed amended to the extent necessary to
         comply with the requirements of such debt clearing services. The
         foregoing sentence applies only to the administration of Bankers'
         Acceptances by the Canadian Lenders and shall not affect the rights and
         obligations of McKesson Canada with respect to any Bankers' Acceptance.

         (e)      Payment of Drawing Purchase Price.

                  (i)      Subject to Section 2.04(b)(iv), each Canadian Lender
         shall, before 12:00 noon (Toronto time) on the applicable Drawing Date,
         pay or cause to be paid, the Drawing Purchase Price in respect of any
         Bankers' Acceptances which such Canadian Lender has purchased or
         arranged to have purchased pursuant to Section 2.04(d)(i) by depositing
         or causing to be deposited such amount to such account maintained by
         the Canadian Administrative Agent at BA Canada as shall have been
         notified to such Canadian Lender by the Canadian Administrative Agent,
         in Canadian Dollars in same day funds. Promptly upon receipt of such
         funds, the Canadian Administrative Agent shall make such funds
         available to McKesson Canada in accordance with reasonable instructions
         provided to the Canadian Administrative Agent by McKesson Canada.

                  (ii)     Bankers' Acceptances purchased by a Canadian Lender
         or its participant hereunder may be held by such Canadian Lender or
         such participant, as the case may be,

                                       36

<PAGE>

         for its own account until maturity or sold by it at any time prior
         thereto in any relevant market therefor in Canada, in such Lender's or
         its participant's sole discretion.

         (f)      Effective Discount Rate Determination. Promptly upon request
of McKesson Canada, the Canadian Administrative Agent shall provide McKesson
Canada an indicative Effective Discount Rate, which rate shall not be binding on
the Canadian Administrative Agent, the Administrative Agent or the Lenders for
purposes of any Drawing or acceptance of Drafts.

         (g)      Payment at Maturity; Cash Collateral.

                  (i)      McKesson Canada shall pay to the Canadian
         Administrative Agent, and there shall become due and payable, at 12:00
         noon (Toronto time) on the maturity date for each Bankers' Acceptance
         an amount in Canadian Dollars in same day funds equal to the Face
         Amount of such Bankers' Acceptance. McKesson Canada shall make each
         payment hereunder in respect of Bankers' Acceptances by deposit of the
         required funds to the Canadian Administrative Agent at the Canada
         Administrative Agent's Office. Upon receipt of such payment, the
         Canadian Administrative Agent will promptly thereafter cause such
         payment to be distributed in like funds in payment of Bankers'
         Acceptances ratably (based on the proportion that the aggregate Face
         Amount of Bankers' Acceptances held by any Canadian Lender or any
         participant thereof maturing on the relevant date bears to the
         aggregate Face Amount of Bankers' Acceptances accepted or held by all
         Canadian Lenders or any participants or assignees thereof maturing on
         such date) to Canadian Lenders for their account and for the account of
         any participant, to the extent of and in accordance with their
         participation. Such payment to the Canadian Administrative Agent shall
         satisfy McKesson Canada's obligations under any Bankers' Acceptances to
         which it relates and each Canadian Lender that has accepted such
         Bankers' Acceptances shall thereafter be solely responsible for the
         payment of such Bankers' Acceptances and shall indemnify and hold
         McKesson Canada harmless against any liabilities, costs or expenses
         incurred by McKesson Canada as a result of any failure by such Canadian
         Lender or such participant to pay such Bankers' Acceptance in
         accordance with its terms.

                  (ii)     If McKesson Canada fails to pay any Bankers'
         Acceptance when due, or to convert or renew the Face Amount of such
         Bankers' Acceptance pursuant to Section 2.04(i), the unpaid amount due
         and payable in respect thereof shall be converted as of such date, and
         without any necessity for McKesson Canada to give a Committed Loan
         Notice in accordance with Section 2.02, to, and thereafter be
         outstanding as, a Canadian Prime Rate Loan made by, the Canadian
         Lenders and shall bear interest calculated and payable as provided in
         Section 2.08. Each Borrower acknowledges, agrees and confirms with the
         Canadian Lenders that the records of each Canadian Lender in respect of
         payment of any Bankers' Acceptance by such Canadian Lender shall be
         binding on McKesson Canada and shall be conclusive evidence (in the
         absence of manifest error) of a Canadian Prime Rate Loan to an amount
         owing by McKesson Canada to such Canadian Lender. McKesson Canada
         further agrees that if an Event of Default or the Maturity Date shall
         occur prior to the date upon which any one or more Bankers' Acceptances
         are payable by a Canadian Lender, thereupon, McKesson Canada shall
         provide such Canadian Lender with funds for the full Face Amounts of
         all such

<PAGE>

         Bankers' Acceptances, notwithstanding the fact that any such Bankers'
         Acceptance may be held by such Canadian Lender in its own right at
         maturity; provided, however, that if for any reason McKesson Canada
         fails to make such payment in respect of any Bankers' Acceptance,
         thereupon McKesson Canada shall be deemed for all purposes to have
         received a Canadian Prime Rate Loan in an amount equal to the face
         amount of such Bankers' Acceptance and McKesson Canada shall pay
         interest thereon at the Canadian Prime Rate until repayment thereof in
         full.

         (h)      Presigned Draft Forms.

                  (i)      To enable the Canadian Lenders to create Bankers'
         Acceptances or complete Drafts in the manner specified in this Section
         2.04, McKesson Canada shall supply each Canadian Lender with such
         number of Drafts as such Canadian Lender may reasonably request, duly
         endorsed and executed on behalf of McKesson Canada by any one or more
         of its authorized officers. Each Canadian Lender shall exercise such
         care in the custody and safekeeping of Drafts as it would exercise in
         the custody and safekeeping of similar property owned by it. Each
         Canadian Lender will, upon request by McKesson Canada, promptly advise
         McKesson Canada of the number and designations, if any, of the
         uncompleted Drafts then held by it. The signatures of such officers may
         be mechanically reproduced in facsimile and Drafts and Bankers'
         Acceptances bearing such facsimile signatures shall be binding upon
         McKesson Canada as if they had been manually signed by such officers.
         Notwithstanding that any of the individuals whose manual or facsimile
         signature appears on any Draft or Bankers' Acceptance as one of such
         officers may no longer hold office at the date thereof or at the date
         of its acceptance by a Canadian Lender or a participant hereunder or at
         any time thereafter, any Draft or Bankers' Acceptance so signed shall
         be valid and binding upon McKesson Canada.

                  (ii)     To facilitate the acceptance of Drafts hereunder,
         McKesson Canada hereby appoints each Canadian Lender as its attorney to
         sign and endorse on its behalf, as and when considered necessary by
         such Canadian Lender in connection with a Drawing, an appropriate
         number of Drafts in the form prescribed by that Canadian Lender. Any
         Draft signed by a Canadian Lender as attorney for McKesson Canada,
         whether signed in handwriting or by the facsimile or mechanical
         signature of an authorized officer of a Canadian Lender, may be dealt
         with by the Canadian Administrative Agent or any Canadian Lender to all
         intents and purposes and shall bind McKesson Canada as if duly signed
         and issued by McKesson Canada.

         (i)      Conversion or Renewal of Bankers' Acceptances. Upon the
maturity of a Bankers' Acceptance, McKesson Canada may elect to (A) renew such
Bankers' Acceptance, by giving a Drawing Notice in accordance with Section
2.04(b)(i); or (B) have all or a portion of the Face Amount of such Bankers'
Acceptance converted to a Eurodollar Rate Loan or Canadian Prime Rate Loan, by
giving a Committed Loan Notice in accordance with Section 2.02. If the Bankers'
Acceptances to be converted cannot be converted into a Eurodollar Rate Loan or
Canadian Prime Rate Loan in an aggregate amount which may be made as a
Eurodollar Rate Loan or Canadian Prime Rate Loan, as the case may be, under this
Agreement, then the amount which cannot be so converted shall be repaid to the
Canadian Administrative Agent for

                                       38

<PAGE>

distribution to the Canadian Lenders in accordance with Section 2.04(g) on the
date of such conversion.

         (j)      Circumstances Making Bankers' Acceptances Unavailable.

                  (i)      If the Canadian Administrative Agent determines in
         good faith, which determination shall be final, conclusive and binding
         upon McKesson Canada, and notifies McKesson Canada that, by reason of
         circumstances affecting the money market (A) there is no market for
         Bankers' Acceptances; or (B) the demand for Bankers' Acceptances is
         insufficient to allow the sale or trading of the Bankers' Acceptances
         created and purchased hereunder; then,

                           (1)      the right of McKesson Canada to request a
                  Drawing shall be suspended until the Canadian Administrative
                  Agent determines that the circumstances causing such
                  suspension no longer exist and the Canadian Administrative
                  Agent so notifies McKesson Canada; and

                           (2)      any Drawing Notice which is outstanding
                  shall be cancelled and the Drawing requested therein shall not
                  be made.

                  (ii)     The Canadian Administrative Agent shall promptly
         notify McKesson Canada and the Administrative Agent of the suspension
         of McKesson Canada's right to request a Drawing and of the termination
         of any such suspension.

         (k)      Prepayments. Except as required by Article VIII, Section 2.05
or Section 2.07, no repayment of a Bankers' Acceptance shall be made by McKesson
Canada to a Canadian Lender prior to the maturity date thereof. Any such
repayment, made as required by Article VIII, Section 2.05 or Section 2.07, shall
be made (unless such repayment has been rescinded or otherwise is required to be
returned by such Canadian Lender to McKesson Canada for any reason) in
accordance with the provisions of Section 2.04(g)(i). Any such payment by
McKesson Canada to the Canadian Administrative Agent shall satisfy McKesson
Canada's obligations under the Bankers' Acceptance to which it relates and, in
the case of a Bankers' Acceptance which has been accepted by a Canadian Lender
or its participant, such Canadian Lender or such participant shall thereafter be
solely responsible for the payment of such Bankers' Acceptance and shall
indemnify and hold McKesson Canada harmless against any liabilities, costs or
expenses incurred by McKesson Canada as a result of any failure by such Canadian
Lender or such participant to pay such Bankers' Acceptance in accordance with
its terms.

         2.05     PREPAYMENTS.

         (a)      The Applicable Borrower may, upon notice to the Applicable
Agent, at any time or from time to time voluntarily prepay Domestic Loans or
Canadian Loans, as the case may be, in whole or in part without premium or
penalty; provided that (i) such notice must be received by the Applicable Agent
not later than 9:00 a.m., in the case of a prepayment of Domestic Loans, and
11:00 a.m., Eastern time, in the case of prepayment of Canadian Loans, (A) three
Business Days prior to any date of prepayment of Eurodollar Rate Loans and (B)
on the date of prepayment of Base Rate Committed Loans and Canadian Prime Rate
Loans; (ii) any prepayment of Domestic Loans shall be in a principal amount of
$5,000,000 or a whole multiple

                                       39

<PAGE>

of $1,000,000 in excess thereof; and (iii) any prepayment of Canadian Loans
shall be in a principal amount of Cdn.$5,000,000 or a whole multiple of Cdn
$1,000,000 in excess thereof or, in each case, if less, the entire principal
amount thereof then outstanding. Each such notice shall specify the date and
amount of such prepayment and the Type(s) of Committed Loans to be prepaid. The
Applicable Agent will promptly notify each Lender or Canadian Lender, as
appropriate, of its receipt of each such notice, and of the amount of such
Lender's Pro Rata Share or Canadian Pro Rata Share, as appropriate, of such
prepayment. If such notice is given by a Borrower, the Applicable Borrower
shall make such prepayment and the payment amount specified in such notice
shall be due and payable on the date specified therein. Any prepayment of a
Eurodollar Rate Loan shall be accompanied by all accrued interest thereon,
together with any additional amounts required pursuant to Section 3.05. Each
such prepayment shall be applied to the Committed Loans of the Lenders in
accordance with their respective Pro Rata Shares or Canadian Pro Rata Shares,
as appropriate.

         (b)      Subject to Section 2.14, if for any reason the Total
Outstandings at any time exceed the Aggregate Commitments then in effect, the
Company shall immediately prepay Loans and/or Cash Collateralize the L/C
Obligations and/or McKesson Canada shall immediately prepay Canadian Loans
and/or cash collateralize Bankers' Acceptances in an aggregate amount equal to
such excess; provided, however, that the Borrowers shall not be required to Cash
Collateralize the L/C Obligations or prepay the Face Amounts of Bankers'
Acceptances pursuant to this Section 2.05(b) unless after the prepayment in full
of the Committed Loans the Total Outstandings exceed the Aggregate Commitments
then in effect.

         (c)      Subject to Section 2.14, if for any reason the Total Canadian
Outstandings at any time exceed the Aggregate Canadian Commitments then in
effect, McKesson Canada shall immediately prepay Canadian Loans and cash
collateralize Bankers' Acceptances in an aggregate amount equal to such excess,
provided that McKesson Canada shall not be required to prepay the Bankers'
Acceptances pursuant to this Section 2.05(c) unless, after prepayment in full of
the Canadian Loans, the Total Canadian Outstandings exceed the Aggregate
Canadian Commitments then in effect.

         2.06     TERMINATION OR REDUCTION OF COMMITMENTS. The Company may, upon
notice to the Applicable Agent, terminate the Aggregate Commitments or the
Aggregate Canadian Commitments, or from time to time permanently reduce the
Aggregate Commitments or the Aggregate Canadian Commitments; provided that (i)
any such notice shall be received by the Applicable Agent not later than 9:00
a.m. or, in the case of a reduction of the Canadian Commitments, 11:00 a.m.,
Eastern time, five Business Days prior to the date of termination or reduction,
(ii) any such partial reduction shall be in an aggregate amount of $10,000,000
or any whole multiple of $1,000,000 in excess thereof, (iii) the Company shall
not terminate or reduce the Aggregate Commitments if, after giving effect
thereto and to any concurrent prepayments hereunder, the Total Outstandings
would exceed the Aggregate Commitments, (iv) the Company shall not terminate or
reduce the Aggregate Canadian Commitments if, after giving effect thereto and to
any concurrent prepayments hereunder, the Total Canadian Outstandings would
exceed the Aggregate Canadian Commitments, (v) if, after giving effect to any
reduction of the Aggregate Commitments, the Letter of Credit Sublimit exceeds
the amount of the Aggregate Commitments, such Sublimit shall be automatically
reduced by the amount of such excess, and (vi) if, after giving effect to any
reduction of the Aggregate Commitments, the Aggregate

                                       40

<PAGE>

Canadian Commitments exceed the amount of the Aggregate Commitments, the
Aggregate Canadian Commitments shall be automatically reduced by the amount of
such excess. The Administrative Agent will promptly notify the Lenders of any
such notice of termination or reduction of the Aggregate Commitments and the
Canadian Administrative Agent will promptly notify the Canadian Lenders of any
such notice of termination or reduction of the Aggregate Canadian Commitments.
Any reduction of the Aggregate Commitments or Aggregate Canadian Commitments
shall be applied to the Commitment of each Lender or the Canadian Commitment of
each Canadian Lender, as the case may be, according to its Pro Rata Share or
its Canadian Pro Rata Share, as the case may be. All facility and utilization
fees accrued until the effective date of any termination of the Aggregate
Commitments shall be paid on the effective date of such termination.

         2.07     REPAYMENT OF LOANS.

         The Applicable Borrower shall repay to the Lenders on the Maturity Date
the aggregate principal amount of its Committed Loans outstanding on such date.
McKesson Canada shall repay to the Lenders on the date that it ceases to be a
Wholly-Owned Subsidiary of the Company the aggregate principal amount of its
Canadian Loans outstanding on such date.

         2.08     INTEREST.

         (a)      Subject to the provisions of Section 2.08(b), (i) each
Eurodollar Rate Loan shall bear interest on the outstanding principal amount
thereof for each Interest Period at a rate per annum equal to the Eurodollar
Rate for such Interest Period plus the Applicable Rate; (ii) each Base Rate
Committed Loan shall bear interest on the outstanding principal amount thereof
from the applicable borrowing date at a rate per annum equal to the Base Rate
plus the Applicable Rate; and (iii) each Canadian Prime Rate Loan shall bear
interest on the outstanding principal amount thereof from the applicable
borrowing date at a rate per annum equal to the Canadian Prime Rate plus the
Applicable Rate.

         (b)      If any amount payable by a Borrower under any Loan Document is
not paid when due (without regard to any applicable grace periods), whether at
stated maturity, by acceleration or otherwise, such amount shall thereafter bear
interest at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Laws. Furthermore,
upon the request of the Required Lenders, while any Event of Default exists, the
Borrowers shall pay interest on the principal amount of all outstanding
Obligations hereunder at a fluctuating interest rate per annum at all times
equal to the Default Rate to the fullest extent permitted by applicable Laws.
Accrued and unpaid interest on past due amounts (including interest on past due
interest) shall be due and payable upon demand.

         (c)      Interest on each Loan shall be due and payable in arrears on
each Interest Payment Date applicable thereto and at such other times as may be
specified herein. Interest hereunder shall be due and payable in accordance with
the terms hereof before and after judgment, and before and after the
commencement of any proceeding under any Debtor Relief Law.

         2.09     FEES. In addition to certain fees described in Sections
2.03(i) and (j) and Section 2.04:

         (a)      Facility Fee. The Company shall pay to the Administrative
Agent for the account of each Lender in accordance with its Pro Rata Share, a
facility fee on the later of the fifth Business Day following the end of each
calendar quarter or the fifth Business Day after the Company has received from
the Administrative Agent a notice setting forth the amount of such fee, which
shall be equal to the Applicable Rate times the actual daily amount of the
Aggregate Commitments (or, if the Aggregate Commitments have terminated, on the
Outstanding Amount of all Committed Loans, Bankers' Acceptances and L/C
Obligations), regardless of usage. The facility fee shall accrue at all times
during the Availability Period (and thereafter so long as any Committed Loans,
Bankers' Acceptances or L/C Obligations remain outstanding), including at any
time during which one or more of the conditions in Article IV are not met, and
shall be due and payable quarterly in arrears on each date specified above
following the end of each calendar quarter, commencing with the first such date
to occur after the Closing Date, through the end of the Availability Period
(and, if applicable, thereafter on demand). The facility fee shall be calculated
quarterly in arrears, and if there is any change in the Applicable Rate during
any quarter, the actual daily amount shall be computed and multiplied by the
Applicable Rate separately for each period during such quarter that such
Applicable Rate was in effect.

         (b)      Utilization Fee. The Company shall pay to the Administrative
Agent for the account of each Lender in accordance with its Pro Rata Share, a
utilization fee of .15% per annum times the Total Outstandings on each day that
the sum of (i) the Total Outstandings existing on such date and (ii) the Total
Outstandings (as such term is defined in the 364-Day Credit Facility) on such
day, exceeds 30% of the sum of (x) the Aggregate Commitments (as defined herein)
existing on such day and (y) the Aggregate Commitments (as such term is defined
in the 364-Day Credit Facility) existing on such day. The utilization fee shall
be due and payable quarterly in arrears on the fifth Business Day following the
end of each calendar quarter, commencing with the first such date to occur after
the Closing Date, and on the Maturity Date. The utilization fee shall be
calculated quarterly in arrears. The utilization fee shall accrue at all times
as set forth in this Section 2.09(b), including at any time during which one or
more of the conditions in Article IV are not met.

         (c)      Other Fees. (i) The Company shall pay to the Arranger and the
Administrative Agent for their own respective accounts fees in the amounts and
at the times specified in the Fee Letter. Such fees shall be fully earned when
paid and shall not be refundable for any reason whatsoever.

                  (ii)     The Borrowers shall pay to the Lenders such fees as
shall have been separately agreed upon in writing in the amounts and at the
times so specified. Such fees shall be fully earned when paid and shall not be
refundable for any reason whatsoever.

         2.10     COMPUTATION OF INTEREST AND FEES. All computations of interest
for Bankers' Acceptances and Drawing Fees, for Canadian Prime Rate Loans and for
Base Rate Loans when the Base Rate is determined by Bank of America's "prime
rate" shall be made on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed. All other computations of fees and interest shall
be made on the basis of a 360-day year and actual days elapsed (which

                                       42

<PAGE>

results in more fees or interest, as applicable, being paid than if computed on
the basis of a 365-day year). Interest shall accrue on each Loan for the day on
which the Loan is made, and shall not accrue on a Loan, or any portion thereof,
for the day on which the Loan or such portion is paid, provided that any Loan
that is repaid on the same day on which it is made shall, subject to Section
2.12(a), bear interest for one day.

         2.11     EVIDENCE OF DEBT.

         (a)      The Credit Extensions made by each Lender shall be evidenced
by one or more accounts or records maintained by such Lender and by the
Applicable Agent in the ordinary course of business. The accounts or records
maintained by the Administrative Agent, the Canadian Administrative Agent and
each Lender shall be conclusive absent manifest error of the amount of the
Credit Extensions made by the Lenders to the Borrowers and the interest and
payments thereon. Any failure to so record or any error in doing so shall not,
however, limit or otherwise affect the obligation of the Borrowers hereunder to
pay any amount owing with respect to the Obligations. In the event of any
conflict between the accounts and records maintained by any Lender and the
accounts and records of either Agent in respect of such matters, the accounts
and records of such Agent shall control in the absence of manifest error. Upon
the request of any Lender made through the Applicable Agent, the applicable
Borrower shall execute and deliver to such Lender (through the Applicable Agent)
a Note, which shall evidence such Lender's Loans in addition to such accounts or
records. Each Lender may attach schedules to its Note and endorse thereon the
date, Type (if applicable), amount and maturity of its Loans and payments with
respect thereto.

         (b)      In addition to the accounts and records referred to in Section
2.11(a), each Lender and the Administrative Agent shall maintain in accordance
with its usual practice accounts or records evidencing the purchases and sales
by such Lender of participations in Letters of Credit. In the event of any
conflict between the accounts and records maintained by the Administrative Agent
and the accounts and records of any Lender in respect of such matters, the
accounts and records of the Administrative Agent shall control in the absence of
manifest error.

         2.12     PAYMENTS GENERALLY.

         (a)      All payments to be made by the Borrowers shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by the Company
hereunder shall be made to the Administrative Agent, for the account of the
Lenders, at the Administrative Agent's Office in Dollars not later than 12:00
noon on the date specified herein, and all payments by McKesson Canada hereunder
shall be made to the Canadian Administrative Agent for the account of the
Canadian Lenders at the Canadian Administrative Agent's Office in Canadian
Dollars not later than 12:00 noon, Eastern time, on the date specified herein,
in each case, in immediately available funds. The Applicable Agent will promptly
distribute to each Lender its Pro Rata Share and to each Canadian Lender its
Canadian Pro Rata Share (or other applicable share as provided herein) of such
payment in like funds as received by wire transfer to such Lender's Lending
Office. All payments received by an Agent after the applicable time specified in
this Section 2.12(a) shall be deemed received on the next succeeding Business
Day and any applicable interest or fee shall continue to accrue.

                                       43

<PAGE>

         (b)      If any payment to be made by a Borrower shall come due on a
day other than a Business Day, payment shall be made on the next following
Business Day, and such extension of time shall be reflected in computing
interest or fees, as the case may be.

         (c)      Unless a Borrower or any Lender has notified an Agent, prior
to the date any payment is required to be made by it to such Agent hereunder,
that such Borrower or such Lender, as the case may be, will not make such
payment, such Agent may assume that such Borrower or such Lender, as the case
may be, has timely made such payment and may (but shall not be so required to),
in reliance thereon, make available a corresponding amount to the Person
entitled thereto. If and to the extent that such payment was not in fact made to
such Agent in immediately available funds, then:

                  (i)      if a Borrower failed to make such payment, each
         Lender shall forthwith on demand repay to the Applicable Agent the
         portion of such assumed payment, if any, that was made available to
         such Lender in immediately available funds, together with interest
         thereon in respect of each day from and including the date such amount
         was made available by such Agent to such Lender to the date such amount
         is repaid to such Agent in immediately available funds at (A) in the
         case of Domestic Loans, the Federal Funds Rate from time to time in
         effect and (B) in the case of Canadian Loans, the Overnight Canadian
         Rate from time to time in effect; and

                  (ii)     subject to the provisions of Section 2.01(b), if any
         Lender failed to make such payment, such Lender shall forthwith on
         demand pay to the Applicable Agent the amount thereof in immediately
         available funds, together with interest thereon for the period from the
         date such amount was made available by such Agent to a Borrower to the
         date such amount is recovered by such Agent (the "Compensation Period")
         at a rate per annum equal to (A) in the case of Domestic Loans, the
         Federal Funds Rate from time to time in effect and (B) in the case of
         Canadian Loans, the Overnight Canadian Rate from time to time in
         effect. If such Lender pays such amount to such Agent, then such amount
         shall constitute such Lender's Committed Loan included in the
         applicable Borrowing. If such Lender does not pay such amount forthwith
         upon the Applicable Agent's demand therefor, such Agent may make a
         demand therefor upon the applicable Borrower, and such Borrower shall
         pay such amount to the Applicable Agent, together with interest thereon
         for the Compensation Period at a rate per annum equal to the rate of
         interest applicable to the applicable Borrowing. Nothing herein shall
         be deemed to relieve any Lender from its obligation to fulfill its
         Commitment or to prejudice any rights which either Agent or Borrower
         may have against any Lender as a result of any default by such Lender
         hereunder.

         A notice of an Agent to any Lender or any Borrower with respect to any
amount owing under this Section 2.12(c) shall be conclusive, absent manifest
error.

         (d)      If any Lender makes available to either Agent funds for any
Loan to be made by such Lender as provided in the foregoing provisions of this
Article II, and such funds are not made available to the Applicable Borrower by
the Administrative Agent because the conditions to the applicable Credit
Extension set forth in Article IV are not satisfied or waived in

                                       44

<PAGE>

accordance with the terms hereof, such Agent shall return such funds (in like
funds as received from such Lender) to such Lender, without interest.

         (e)      The obligations of the Lenders hereunder to make Committed
Loans, to fund participations in Letters of Credit and to purchase Bankers'
Acceptances are several and not joint. The failure of any Lender to make any
Committed Loan, to fund any such participation or to make any such purchase on
any date required hereunder shall not relieve any other Lender of its
corresponding obligation to do so on such date, and no Lender shall be
responsible for the failure of any other Lender to so make its Committed Loan,
fund its participation or purchase its Bankers' Acceptance.

         (f)      Nothing herein shall be deemed to obligate any Lender to
obtain the funds for any Loan in any particular place or manner or to constitute
a representation by any Lender that it has obtained or will obtain the funds for
any Loan in any particular place or manner.

         2.13     SHARING OF PAYMENTS. If, other than as expressly provided
elsewhere herein, any Lender shall obtain on account of the Committed Loans made
by it, the Bankers' Acceptance Facility or the participations in L/C Obligations
held by it, any payment (whether voluntary, involuntary, through the exercise of
any right of set-off, or otherwise) in excess of its ratable share (or other
share contemplated hereunder) thereof, such Lender shall immediately (a) notify
the Administrative Agent of such fact, and (b) purchase from the other Lenders
such participations in the Committed Loans made by them or Bankers' Acceptances
and/or such subparticipations in the participations in L/C Obligations held by
them, as the case may be, as shall be necessary to cause such purchasing Lender
to share the excess payment in respect of such Committed Loans, Bankers'
Acceptances or such participations, as the case may be, pro rata with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the purchasing Lender under any of the circumstances
described in Section 11.06 (including pursuant to any settlement entered into by
the purchasing Lender in its discretion), such purchase shall to that extent be
rescinded and each other Lender shall repay to the purchasing Lender the
purchase price paid therefor, together with an amount equal to such paying
Lender's ratable share (according to the proportion of (i) the amount of such
paying Lender's required repayment to (ii) the total amount so recovered from
the purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered, without further
interest thereon; provided further that, for purposes of this Section 2.13, and
subject to Section 2.01(b)(ii), no Lender other than a Canadian Lender that is a
Canadian Resident may purchase any portion of or any interest in a Canadian Loan
or Bankers' Acceptance. Each Borrower agrees that any Lender so purchasing a
participation from another Lender may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 11.09) with respect to such participation as fully as if such Lender
were the direct creditor of such Borrower in the amount of such participation.
The Administrative Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section 2.13 and will in each case notify the Lenders following any such
purchases or repayments. Each Lender that purchases a participation pursuant to
this Section 2.13 shall from and after such purchase have the right to give all
notices, requests, demands, directions and other communications under this
Agreement with respect to the portion of the Obligations purchased to the same
extent as though the purchasing Lender were the original owner of the
Obligations purchased.

         2.14     CURRENCY EXCHANGE FLUCTUATIONS.

         Subject to Section 3.02, if on any Computation Date the Administrative
Agent or the Canadian Administrative Agent shall have determined that (a) the
Total Outstandings exceed the Aggregate Commitments by more than $3,000,000, or
(b) the Total Canadian Outstandings exceed the Aggregate Canadian Commitments by
more than $3,000,000, in either event due to a change in applicable rates of
exchange between Dollars and Canadian Dollars, then the Administrative Agent
shall give notice to the Borrowers that a prepayment is required under this
Section 2.14, and the Borrowers agree thereupon to make prepayments of Loans
such that, after giving effect to such prepayment, the Total Outstandings do not
exceed the Aggregate Commitments and the Total Canadian Outstandings do not
exceed the Aggregate Canadian Commitments. No prepayment of Loans is required
pursuant to this Section 2.14 or Section 2.05 in the event that the Total
Outstandings exceed the Aggregate Commitments by $3,000,000 or less, or the
Total Canadian Outstandings exceed the Aggregate Canadian Commitments by
$3,000,000 or less, in either event solely due to a change in applicable rates
of exchange between Dollars and Canadian Dollars.

         2.15     INCREASE IN COMMITMENTS.

         (a)      Provided there exists no Default, upon notice to the
Administrative Agent (which shall promptly notify the Lenders), the Company may
from time to time, request an increase in the Aggregate Commitments (as such
term is defined in this Agreement) and the Aggregate Commitments (as such term
is defined in the 364-Day Credit Facility) collectively by an aggregate amount
(for all such requests) not exceeding $400,000,000; provided, however, that any
such increase in the Commitments shall (i) prior to the Revolving Loan Maturity
Date (as such term is defined in the 364-Day Credit Facility), be allocated
between the Commitments (as such term is defined in this Agreement) and the
Commitments (as such term is defined in the 364-Day Credit Facility) on a pro
rata basis such that the proportions of each such type of Commitment as a
portion of the total Commitments are equal; and (ii) on or after the Revolving
Loan Maturity Date (as such term is defined in the 364-Day Credit Facility), be
allocated entirely to the Commitments (as such term is defined in this
Agreement). At the time of sending such notice, the Company (in consultation
with the Administrative Agent) shall specify the time period within which each
Lender is requested to respond (which shall in no event be less than ten
Business Days from the date of delivery of such notice to the Lenders). Each
Lender shall notify the Administrative Agent within such time period whether or
not it agrees to increase its Commitment and, if so, whether by an amount equal
to, greater than, or less than its Pro Rata Share of such requested increase.
Any Lender not responding within such time period shall be deemed to have
declined to increase its Commitment. The Administrative Agent shall notify the
Company and each Lender of the Lenders' responses to each request made
hereunder. To achieve the full amount of a requested increase, the Company may
also invite additional Eligible Assignees to become Lenders pursuant to a
joinder agreement in form and substance satisfactory to the Administrative Agent
and its counsel. Notwithstanding the foregoing provisions of this Section
2.15(a), during the first 90 days following the Closing Date, the Company may
invite Eligible Assignees to become Lenders under this Agreement in connection
with a requested increase without first providing any Lender with the
opportunity to increase its Commitment as provided above.

                                       46

<PAGE>

         (b)      If the Aggregate Commitments are increased in accordance with
this Section 2.15, the Administrative Agent and the Company shall determine the
effective date (the "Increase Effective Date") and the final allocation of such
increase. The Administrative Agent shall promptly notify the Company and the
Lenders of the final allocation of such increase and the Increase Effective
Date. As a condition precedent to such increase, the Company shall deliver to
the Administrative Agent a certificate of each Loan Party dated as of the
Increase Effective Date signed by a Responsible Officer of such Loan Party (i)
certifying and attaching the resolutions adopted by such Loan Party approving or
consenting to such increase, and (ii) in the case of the Company, certifying
that, before and after giving effect to such increase, (A) the representations
and warranties contained in Article V and the other Loan Documents are true and
correct on and as of the Increase Effective Date, except to the extent that such
representations and warranties specifically refer to an earlier date, in which
case they are true and correct as of such earlier date, and except that, for
purposes of this Section 2.15, (1) the representation and warranty contained in
Section 5.08(a) shall be deemed to refer to the most recent statements furnished
pursuant to Sections 6.01(a) and (b), respectively, and (2) the reference to the
Closing Date in Section 5.05(b) and Section 5.08(b) shall be deemed to refer to
the Increase Effective Date and (B) no Default exists. The Company shall prepay
any Committed Loans outstanding on the Increase Effective Date (and pay any
additional amounts required pursuant to Section 3.05) to the extent necessary to
keep the outstanding Committed Loans ratable with any revised Pro Rata Shares
arising from any nonratable increase in the Commitments under this Section 2.15.

         (c)      In the event of an increase in Commitments pursuant to this
Section 2.15, the provisions of this Section 2.15 shall govern any conflicts
with provisions in Sections 2.13 or 11.01.

         2.16     UTILIZATION OF COMMITMENTS IN CANADIAN DOLLARS.

         (a)      The Administrative Agent will determine the Dollar Equivalent
amount with respect to any (i) Borrowing comprised of Canadian Loans that are
Eurodollar Rate Loans as of the date which is three Business Days prior to the
date of the requested Borrowing, (ii) Bankers' Acceptance or Borrowing comprised
of Canadian Prime Rate Loans, one day prior to the requested date of Borrowing,
(iii) outstanding Canadian Loans or Bankers' Acceptances as of the last Business
Day of each month, and (iv) conversions to or continuation of Canadian Loans as
of the date the related Committed Loan Notice is received by the Canadian
Administrative Agent or, if such conversion or continuation is performed in
accordance with Section 2.16(b) or Section 3.02, as of, in the case of Section
2.16(b), the date that the request by the Required Lenders is received by the
Administrative Agent or, in the case of Section 3.02, the date that the notice
by the Administrative Agent is received by the Borrowers and the Lenders (each
such date under clauses (i) through (iv) a "Computation Date").

         (b)      Notwithstanding anything herein to the contrary, during the
existence of a Default or an Event of Default, upon the request of the Required
Lenders, all or any part of any outstanding Canadian Loans consisting of
Eurodollar Rate Loans shall be converted into Canadian Prime Rate Loans with
effect from the last day of the Interest Period with respect to any such
Canadian Loans. The Administrative Agent will promptly notify the Borrowers of
any such conversion request.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         3.01     TAXES.

         (a)      Any and all payments by the Borrowers to or for the account of
any Agent or any Lender under any Loan Document shall be made free and clear of
and without deduction for any and all present or future taxes, duties, levies,
imposts, deductions, assessments, fees, withholdings or similar charges, and all
liabilities with respect thereto, excluding, in the case of each Agent and each
Lender, taxes imposed on or measured by its net income, taxable income, taxable
capital or similar measure and franchise taxes imposed on it (in lieu of net
income taxes), by the jurisdiction (or any political subdivision thereof) under
the Laws of which such Agent or such Lender, as the case may be, is organized or
maintains a lending office or carries on business through a permanent
establishment (all such non-excluded taxes, duties, levies, imposts, deductions,
assessments, fees, withholdings or similar charges, and liabilities being
hereinafter referred to as "Taxes"). If the Borrowers shall be required by any
Laws to deduct any Taxes from or in respect of any sum payable under any Loan
Document to any Agent or any Lender, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 3.01), each of such
Agent and such Lender receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Applicable Borrower shall make such
deductions, (iii) the Applicable Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable
Laws, and (iv) within 30 days after the date of such payment, the Applicable
Borrower shall furnish to the Applicable Agent (which shall forward the same to
such Lender) the original or a certified copy of a receipt evidencing payment
thereof.

         (b)      In addition, each Borrower agrees to pay any and all present
or future stamp, court or documentary taxes and any other excise or property
taxes or charges or similar levies which arise from any payment made under any
Loan Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "Other Taxes").

         (c)      If a Borrower shall be required to deduct or pay any Taxes or
Other Taxes from or in respect of any sum payable under any Loan Document to
either Agent or any Lender, that Borrower shall also pay to such Agent or to
such Lender, as the case may be, at the time interest is paid, such additional
amount that such Agent or such Lender specifies is necessary to preserve the
after-tax yield (after factoring in all taxes, including taxes imposed on or
measured by net income) that such Agent or such Lender would have received if
such Taxes or Other Taxes had not been imposed.

         (d)      Each Borrower agrees to indemnify each Agent and each Lender
for (i) the full amount of Taxes and Other Taxes (including any Taxes or Other
Taxes imposed or asserted by any jurisdiction on amounts payable under this
Section 3.01) paid by such Agent and such Lender, (ii) amounts payable under
Section 3.01(c) and (iii) any liability (including additions to tax, penalties,
interest and expenses) arising therefrom or with respect thereto, in each case
whether or not such Taxes or Other Taxes were correctly or legally imposed or
asserted by the

                                       48

relevant Governmental Authority. Payment under this Section 3.01(d) shall be
made within 30 days after the date the Lender or the Applicable Agent makes a
demand therefor.

         (e)      If any Lender or Agent, as applicable, receives a refund
(whether by way of a direct payment or by offset) of any Taxes or Other Taxes
paid by a Borrower under this Section 3.01 which, in the reasonable good faith
judgment of such Lender or Agent, as the case may be, is allocable to such
payment, the amount of such refund (net of all reasonable out-of-pocket expenses
of such Lender or Agent) shall be paid to such Borrower if (i) payment of the
Taxes or Other Taxes being refunded has been made in full as and when required
pursuant to this Section 3.01 and (ii) such Borrower agrees in writing to repay
the amount of such refund, together with interest thereon, to the applicable
Lender or Agent in the event such Lender or Agent is required to repay such
refund to the Governmental Authority that imposed the Tax or Other Tax being
refunded.

         3.02     ILLEGALITY.

         (a)      If any Lender determines that any Law has made it unlawful, or
that any Governmental Authority has asserted that it is unlawful, for any Lender
or its applicable Lending Office to make, maintain or fund Eurodollar Rate Loans
(whether payable in Dollars or Canadian Dollars), or to determine or charge
interest rates based upon the Eurodollar Rate, then, on notice thereof by such
Lender to the Borrowers through the Applicable Agent, any obligation of such
Lender to make or continue Eurodollar Rate Loans or to convert Base Rate
Committed Loans or Canadian Prime Rate Loans, as the case may be, to Eurodollar
Rate Loans shall be suspended until such Lender notifies the Applicable Agent
and the Applicable Borrower that the circumstances giving rise to such
determination no longer exist. Upon receipt of such notice, the Applicable
Borrower shall, upon demand from such Lender (with a copy to the Applicable
Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such
Lender to Base Rate Loans or Canadian Prime Rate Loans, as the case may be,
either on the last day of the Interest Period therefor, if such Lender may
lawfully continue to maintain such Eurodollar Rate Loans to such day, or
immediately, if such Lender may not lawfully continue to maintain such
Eurodollar Rate Loans. Upon any such prepayment or conversion, the Applicable
Borrower shall also pay accrued interest on the amount so prepaid or converted.
Each Lender agrees to designate a different Lending Office if such designation
will avoid the need for such notice and will not, in the good faith judgment of
such Lender, otherwise be materially disadvantageous to such Lender.

         (b)      Upon any Lender's giving notice and suspending its obligations
relating to Eurodollar Rate Loans in accordance with Section 3.02(a), the
Company may replace such Lender in accordance with Section 11.16.

         3.03     INABILITY TO DETERMINE RATES. If the Required Lenders
determine that for any reason adequate and reasonable means do not exist for
determining the Eurodollar Base Rate for any requested Interest Period with
respect to a proposed Eurodollar Rate Loan, or that the Eurodollar Base Rate for
any requested Interest Period with respect to a proposed Eurodollar Rate Loan
does not adequately and fairly reflect the cost to such Lenders of funding such
Loan, the Administrative Agent will promptly so notify the Borrowers and each
Lender. Thereafter, the obligation of the Lenders (including Canadian Lenders)
to make or maintain Eurodollar Rate

                                       49

<PAGE>

Loans shall be suspended until the Administrative Agent (upon the instruction of
the Required Lenders) revokes such notice. Upon receipt of such notice, the
Borrowers may revoke any pending request for a Borrowing of, conversion to or
continuation of Eurodollar Rate Loans or, failing that, will be deemed to have
converted such request into a request for a Borrowing of Base Rate Loans or
Canadian Prime Rate Loans, as the case may be, in the amount specified therein.

         3.04     INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY.

         (a)      If any Lender, including any Canadian Lender, determines that
as a result of the introduction of or any change in or in the interpretation of
any Law, or such Lender's compliance therewith, in either case after the Closing
Date, there shall be any increase in the cost to such Lender of agreeing to make
or making, funding or maintaining Eurodollar Rate Loans, agreeing to accept or
accepting, funding or maintaining Drafts or Bankers' Acceptances, or (as the
case may be) issuing or participating in Letters of Credit, or a reduction in
the amount received or receivable by such Lender in connection with any of the
foregoing (excluding for purposes of this Section 3.04(a) any such increased
costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to
which Section 3.01 shall govern), (ii) changes in the basis of taxation of
overall net income or overall gross income by the United States or any foreign
jurisdiction or any political subdivision of either thereof under the Laws of
which such Lender is organized or has its Lending Office, and (iii) reserve
requirements utilized in the determination of the Eurodollar Rate), then from
time to time upon demand of such Lender (with a copy of such demand to the
Administrative Agent and the Canadian Administrative Agent, if applicable), the
Applicable Borrower shall pay to such Lender such additional amounts as will
compensate such Lender for such increased cost or reduction; provided that no
Lender shall be entitled to receive additional amounts with respect to any
period prior to six months prior to making such demand.

         (b)      If any Lender determines that the introduction of any Law
regarding capital adequacy or any change therein or in the interpretation
thereof, in either case after the Closing Date, or compliance by such Lender (or
its Lending Office) therewith, has the effect of reducing the rate of return on
the capital of such Lender or any corporation controlling such Lender as a
consequence of such Lender's obligations hereunder (taking into consideration
its policies with respect to capital adequacy and such Lender's desired return
on capital), then from time to time upon demand of such Lender (with a copy of
such demand to the Administrative Agent), the Company shall pay to such Lender
such additional amounts as will compensate such Lender for such reduction;
provided that no Lender shall be entitled to receive additional amounts with
respect to any period prior to six months prior to making such demand.

         3.05     FUNDING LOSSES. Upon demand of any Lender (with a copy to the
Administrative Agent) from time to time, the Company shall promptly compensate
such Lender for and hold such Lender harmless from any loss, cost or expense
incurred by it as a result of:

         (a)      any continuation, conversion, payment or prepayment of any
Eurodollar Rate Loan on a day other than the last day of the Interest Period for
such Loan (whether voluntary, mandatory, automatic, by reason of acceleration,
or otherwise);

                                       50

<PAGE>

         (b)      any failure by a Borrower (for a reason other than the failure
of such Lender to make a Loan) to prepay, borrow, continue or convert any
Eurodollar Rate Loan on the date or in the amount notified by such Borrower; or

         (c)      any assignment of a Eurodollar Rate Loan on a day other than
the last day of the Interest Period therefor as a result of a request by the
Company pursuant to Section 11.16;

including any loss of anticipated profits and any loss or expense arising from
the liquidation or reemployment of funds obtained by it to maintain such Loan or
from fees payable to terminate the deposits from which such funds were obtained.

For purposes of calculating amounts payable by the Company to the Lenders under
this Section 3.05, each Lender shall be deemed to have funded each Eurodollar
Rate Loan made by it at the Eurodollar Base Rate used in determining the
Eurodollar Rate for such Loan by a matching deposit or other borrowing in the
London interbank eurodollar market for a comparable amount and for a comparable
period, whether or not such Eurodollar Rate Loan was in fact so funded.

         3.06     MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION.

         (a)      A certificate of the Administrative Agent, the Canadian
Administrative Agent or any Lender claiming compensation under this Article III
and setting forth the additional amount or amounts to be paid to it hereunder
shall be conclusive in the absence of manifest error. In determining such
amount, the Administrative Agent, the Canadian Administrative Agent or such
Lender may use any reasonable averaging and attribution methods.

         (b)      Upon any Lender's making a claim for compensation under
Section 3.04 or if any Borrower is required to pay amounts to any Lender under
Section 3.01 as a result of any Taxes or Other Taxes, in each case the Company
may replace such Lender in accordance with Section 11.16.

         3.07     SURVIVAL. All of the Borrowers' obligations under this Article
III shall survive termination of the Aggregate Commitments and repayment of all
other Obligations hereunder.

                                   ARTICLE IV.

Notice requesting only a conversion of Committed Loans to the other Type, or a
continuation of Eurodollar Rate Loans) is subject to the following conditions
precedent:

         (a)      The representations and warranties of each Borrower contained
in Article V or any other Loan Document, or which are contained in any document
furnished at any time under or in connection herewith or therewith, shall be
true and correct on and as of the date of such Credit Extension, except to the
extent that such representations and warranties specifically refer to an earlier
date, in which case they shall be true and correct as of such earlier date, and
except

                                       53

<PAGE>

that for purposes of this Section 4.02, the representations and warranties

         (b)      No Default shall exist, or would result from such proposed

                         REPRESENTATIONS AND WARRANTIES

         Each Borrower represents and warrants (which representations and
warranties in the case of McKesson Canada shall be limited to McKesson Canada
and its Subsidiaries and other facts and circumstances known to McKesson Canada
and its Subsidiaries) to the Administrative Agent, the Canadian Administrative
Agent and each Lender that:

         5.01     CORPORATE EXISTENCE AND POWER. The Company and each of its

the laws of the jurisdiction of its incorporation or organization;

         (b)      has the power and authority and all required governmental

                                       54

<PAGE>

except, (i) with respect to Subsidiaries of the Company other than Material
Subsidiaries, to the extent that the failure to do so could not reasonably be
expected to have a Material Adverse Effect, and (ii) with respect to the Company
and its Material Subsidiaries (A) in each case referred to in clause (c) or
clause (d), to the extent that the failure to do so could not reasonably be
expected to have a Material Adverse Effect and (B) in each case referred to in
clause (d), the Disclosed Matters.

         5.02     CORPORATE AUTHORIZATION; NO CONTRAVENTION. The execution,
delivery and performance by each Borrower of this Agreement and each other Loan
Document to which such Borrower is party, and any Borrowing as of the date of
such Borrowing have been duly authorized by all necessary corporate action, and
do not and will not:

         (a)      contravene the terms of any Borrower's Organization Documents;

         (b)      conflict with or result in any breach or contravention of, or
the creation of any Lien under, any document evidencing any Contractual
Obligation to which any Borrower is a party or any order, injunction, writ or
decree of any Governmental Authority to which any Borrower or its property is
subject; or

         (c)      violate any Requirement of Law.

         5.03     GOVERNMENTAL AUTHORIZATION. No approval, consent, exemption,
authorization, or other action by, or notice to, or filing with, any
Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or enforcement against, any Borrower of
the Agreement or any other Loan Document.

         5.04     BINDING EFFECT. This Agreement and each other Loan Document to
which each Borrower is a party constitute the legal, valid and binding
obligations of such Borrower, enforceable against such Borrower in accordance
with their respective terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, or similar laws affecting the enforcement of
creditors' rights generally or by equitable principles relating to
enforceability.

         5.05     LITIGATION.

         Except as disclosed in the Company's Annual Report on Form 10-K for the
fiscal year ended March 31, 2002 and the Company's Quarterly Report on Form 10-Q
for the quarter ended June 30, 2002, each as filed with the SEC (including but
not limited to the Disclosed Matters), there are no actions, suits, proceedings,
claims or disputes pending, or to the best knowledge of each Borrower,
threatened or contemplated, at law, in equity, in arbitration or before any
Governmental Authority, against the Company, or its Subsidiaries or any of their
respective properties which:

         (a)      purport to affect or pertain to this Agreement or any other
Loan Document, or any of the transactions contemplated hereby or thereby; or

         (b)      if determined adversely to the Company or its Subsidiaries,
would reasonably be expected to have a Material Adverse Effect as of the Closing
Date. No injunction, writ, temporary restraining order or any order of any
nature has been issued by any court or other

                                       55

<PAGE>

Governmental Authority purporting to enjoin or restrain the execution, delivery
or performance of this Agreement or any other Loan Document, or directing that
the transactions provided for herein or therein not be consummated as herein or
therein provided.

         5.06     NO DEFAULT. No Default or Event of Default exists or would
result from the incurring of any Obligations by any Borrower. As of the Closing
Date, neither the Company nor any Subsidiary is in default under or with respect
to any Contractual Obligation in any respect which, individually or together
with all such defaults, could reasonably be expected to have a Material Adverse
Effect as of the Closing Date, or that would, if such default had occurred after
the Closing Date, create an Event of Default under Section 8.01(e).

         5.07     USE OF PROCEEDS; MARGIN REGULATIONS. The proceeds of the Loans
are to be used solely for the purposes set forth in Section 6.10. Neither the
Company nor any Subsidiary is generally engaged in the business of purchasing or
selling Margin Stock or extending credit for the purpose of purchasing or
carrying Margin Stock.

         5.08     FINANCIAL CONDITION. (a) The (i) Audited Financial Statements
and (ii) unaudited consolidated financial statements of the Company and its
Subsidiaries dated June 30, 2002, and the related consolidated statements of
operations, shareholders' equity and cash flows for the three months ended on
that date:

                  (A)      were prepared in accordance with GAAP consistently
         applied throughout the period covered thereby, except as otherwise
         expressly noted therein, subject in the case of the unaudited
         statements to ordinary, good faith year end audit adjustments;

                  (B)      fairly present the financial condition of the Company
         and its Subsidiaries as of the date thereof and results of operations
         for the period covered thereby; and

                  (C)      show all material indebtedness and other liabilities,
         direct or contingent, of the Company and its consolidated Subsidiaries
         as of the date thereof required to be shown in accordance with GAAP.

         (b)      As of the Closing Date, since March 31, 2002, there has been
no Material Adverse Effect.

         5.09     REGULATED ENTITIES. None of the Company, any Person
controlling the Company, or any Subsidiary, is an "investment company" within
the meaning of the Investment Company Act of 1940. Neither Borrower is subject
to regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act, any state public utilities code, or any
other Federal, state or other statute or regulation limiting its ability to
incur Indebtedness.

         5.10     NO BURDENSOME RESTRICTIONS. Neither the Company nor any
Subsidiary is a party to or bound by any Contractual Obligation, or subject to

of that portion of the Obligations constituting unpaid principal of the Bankers'
Acceptances, in each case ratably among the Lenders in proportion to the
respective amounts described in this clause Fourth held by them;

                                       65

         Fifth, to the Administrative Agent for the account of the L/C Issuer,
to Cash Collateralize that portion of L/C Obligations comprised of the aggregate
undrawn amount of Letters of Credit; and

         Last, the balance, if any, after all of the Obligations have been
indefeasibly paid in full, to the Applicable Borrower or as otherwise required
by Law.

Subject to Section 2.03(c), amounts used to Cash Collateralize the aggregate
undrawn amount of Letters of Credit pursuant to clause Fifth above shall be
applied to satisfy drawings under such Letters of Credit as they occur. If any
amount remains on deposit as Cash Collateral after all Letters of Credit have
either been fully drawn or expired, such remaining amount shall be applied to
the other Obligations, if any, in the order set forth above.

                                  ARTICLE IX.
                              ADMINISTRATIVE AGENT

         9.01     APPOINTMENT AND AUTHORIZATION OF AGENTS.

         (a)      Each Lender hereby irrevocably appoints, designates and
authorizes the Administrative Agent, and each Canadian Lender hereby irrevocably
appoints, designates and authorizes the Canadian Administrative Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere herein or in
any other Loan Document, no Agent shall have any duties or responsibilities,
except those expressly set forth herein, nor shall either Agent have or be
deemed to have any fiduciary relationship with any Lender or participant, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against either Agent. Without limiting the generality of the
foregoing sentence, the use of the term "agent" herein and in the other Loan
Documents with reference to the Administrative Agent and the Canadian
Administrative Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable Law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

         (b)      The L/C Issuer shall act on behalf of the Lenders with respect
to any Letters of Credit issued by it and the documents associated therewith,
and the L/C Issuer shall have all of the benefits and immunities (i) provided to
the Administrative Agent in this Article IX and under Section 11.05 with respect
to any acts taken or omissions suffered by the L/C Issuer, or any other
Indemnified Liabilities of the L/C Issuer, arising out of or in connection with
Letters of Credit issued by it or proposed to be issued by it and the
applications and agreements for letters of credit pertaining to such Letters of
Credit as fully as if the term "Administrative Agent" as used in this Article IX
and in the definition of "Agent-Related Person" included the L/C Issuer with
respect to such acts or omissions or other Indemnified Liabilities, and (ii) as
additionally provided herein with respect to the L/C Issuer.

                                       66

<PAGE>

         9.02     DELEGATION OF DUTIES. Each Agent may execute any of its duties
under this Agreement or any other Loan Document by or through agents, employees
or attorneys-in-fact and shall be entitled to advice of counsel and other
consultants or experts concerning all matters pertaining to such duties. No
Agent shall be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects in the absence of gross negligence or willful
misconduct.

         9.03     LIABILITY OF AGENTS. No Agent-Related Person shall (a) be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct
in connection with its duties expressly set forth herein), or (b) be responsible
in any manner to any Lender or participant for any recital, statement,
representation or warranty made by any Loan Party or any officer thereof,
contained herein or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by
either Agent under or in connection with, this Agreement or any other Loan
Document, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
any Loan Party or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Lender or participant to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of any Loan Party or any Affiliate thereof.

         9.04     RELIANCE BY AGENTS.

         (a)      Each Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, electronic mail message, statement or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons, and upon advice
and statements of legal counsel (including counsel to any Loan Party),
independent accountants and other experts selected by such Agent. Each Agent
shall be fully justified in failing or refusing to take any action under any
Loan Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate and, if it so requests, it shall first
be indemnified to its satisfaction by the Lenders against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. Each Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement or any other Loan
Document in accordance with a request or consent of the Required Lenders (or
such greater number of Lenders as may be expressly required hereby in any
instance) and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders.

         (b)      For purposes of determining compliance with the conditions
specified in Section 4.01, each Lender that has signed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter required thereunder to be consented to or approved by
or acceptable or satisfactory to a Lender unless the Administrative Agent shall
have received notice from such Lender prior to the proposed Closing Date
specifying its objection thereto.

                                       67

<PAGE>

         9.05     NOTICE OF DEFAULT. No Agent shall be deemed to have knowledge
or notice of the occurrence of any Default, except with respect to defaults in
the payment of principal, interest and fees required to be paid to such Agent
for the account of the Lenders, unless such Agent shall have received written
notice from a Lender or a Borrower referring to this Agreement, describing such
Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default as
may be directed by the Required Lenders in accordance with Article VIII;
provided, however, that unless and until the Administrative Agent has received
any such direction, the Administrative Agent may (but shall not be obligated to)
take such action, or refrain from taking such action, with respect to such
Default as it shall deem advisable or in the best interest of the Lenders.

         9.06     CREDIT DECISION; DISCLOSURE OF INFORMATION BY AGENTS. Each
Lender acknowledges that no Agent-Related Person has made any representation or
warranty to it, and that no act by the Agents hereafter taken, including any
consent to and acceptance of any assignment or review of the affairs of any Loan
Party or any Affiliate thereof, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Lender as to any matter,
including whether Agent-Related Persons have disclosed material information in
their possession. Each Lender represents to the Agents that it has,
independently and without reliance upon any Agent-Related Person and based on
such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Loan Parties
and their respective Subsidiaries, and all applicable bank or other regulatory
Laws relating to the transactions contemplated hereby, and made its own decision
to enter into this Agreement and to extend credit to any Borrower hereunder.
Each Lender also represents that it will, independently and without reliance
upon any Agent-Related Person and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of any Borrower. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
an Agent herein, no Agent shall have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, prospects,
operations, property, financial and other condition or creditworthiness of any
of the Loan Parties or any of their respective Affiliates which may come into
the possession of any Agent-Related Person.

         9.07     INDEMNIFICATION OF AGENTS. Whether or not the transactions
contemplated hereby are consummated, the Lenders shall indemnify upon demand
each Agent-Related Person (to the extent not reimbursed by or on behalf of any
Loan Party and without limiting the obligation of any Loan Party to do so), pro
rata, and hold harmless each Agent-Related Person from and against any and all
Indemnified Liabilities incurred by it; provided, however, that no Lender shall
be liable for the payment to any Agent-Related Person of any portion of such
Indemnified Liabilities to the extent determined in a final, nonappealable
judgment by a court of competent jurisdiction to have resulted from such
Agent-Related Person's own gross negligence or willful misconduct; provided,
however, that no action taken in accordance with the directions of the Required
Lenders shall be deemed to constitute gross negligence or willful misconduct for

                                       68

<PAGE>

purposes of this Section 9.07. Without limitation of the foregoing, each Lender
shall reimburse the Agents upon demand for its ratable share of any costs or
out-of-pocket expenses (including Attorney Costs) incurred by either Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that such Agent is not
reimbursed for such expenses by or on behalf of the Borrowers. The undertaking
in this Section 9.07 shall survive termination of the Aggregate Commitments, the
payment of all other Obligations and the resignation of either Agent.

         9.08     AGENTS IN THEIR INDIVIDUAL CAPACITIES. Bank of America, BA
Canada and their respective Affiliates may make loans to, issue letters of
credit for the account of, accept deposits from, acquire equity interests in and
generally engage in any kind of banking, trust, financial advisory, underwriting
or other business with each of the Loan Parties and their respective Affiliates
as though Bank of America were not the Administrative Agent hereunder and BA
Canada were not the Canadian Administrative Agent hereunder and without notice
to or consent of the Lenders. The Lenders acknowledge that, pursuant to such
activities, Bank of America, BA Canada or one of their Affiliates may receive
information regarding any Loan Party or its Affiliates (including information
that may be subject to confidentiality obligations in favor of such Loan Party
or such Affiliate) and acknowledge that no Agent shall be under any obligation
to provide such information to them. With respect to their Loans, Bank of
America and BA Canada shall have the same rights and powers under this Agreement
as any other Lender and may exercise such rights and powers as though Bank of
America were not the Administrative Agent and BA Canada were not the Canadian
Administrative Agent hereunder, and the terms "Lender" and "Lenders" include
Bank of America and BA Canada in their individual capacities.

         9.09     SUCCESSOR AGENTS. Either Agent may resign as an Agent upon 30
days' notice to the Lenders. If the Administrative Agent or the Canadian
Administrative Agent resigns under this Agreement, the Required Lenders shall
appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall be consented to by the Company at all times other than
during the existence of an Event of Default (which consent of the Company shall
not be unreasonably withheld or delayed). If no successor agent is appointed
prior to the effective date of the resignation of such Agent, such Agent may
appoint, after consulting with the Lenders and the Company, a successor agent
from among the Lenders. Upon the acceptance of its appointment as successor
agent hereunder, the Person acting as such successor agent shall succeed to all
the rights, powers and duties of the retiring Agent and, if the Administrative
Agent has resigned, the term "Administrative Agent" shall mean such successor
administrative agent and, if the Canadian Administrative Agent has resigned, the
term "Canadian Administrative Agent" shall mean such successor Canadian
administrative agent and the retiring Agent's appointment, powers and duties as
Agent shall be terminated. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article IX and Sections 11.04 and 11.05 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement. If no successor agent has accepted
appointment as Agent by the date which is 30 days following a retiring Agent's
notice of resignation, the retiring Agent's resignation shall nevertheless
thereupon become effective and the Lenders shall perform all of the duties of
the Agent hereunder until such time, if any, as the Required Lenders appoint a
successor agent as provided for above.

         9.10     ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIM. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to any Loan Party, the Administrative Agent (irrespective of
whether the principal of any Loan, Bankers' Acceptance or L/C Obligation shall
then be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Administrative Agent shall have made any demand on
any Borrower) shall be entitled and empowered, by intervention in such
proceeding or otherwise

                  (a)      to file and prove a claim for the whole amount of the
         principal and interest owing and unpaid in respect of the Loans, L/C
         Obligations and all other Obligations that are owing and unpaid and to
         file such other documents as may be necessary or advisable in order to
         have the claims of the Lenders and the Administrative Agent (including
         any claim for the reasonable compensation, expenses, disbursements and
         advances of the Lenders and the Administrative Agent and their
         respective agents and counsel and all other amounts due the Lenders and
         the Administrative Agent under Sections 2.03(i) and (j), 2.09 and
         11.04) allowed in such judicial proceeding; and

                  (b)      to collect and receive any monies or other property
         payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to the Administrative Agent and, in the event
that the Administrative Agent shall consent to the making of such payments
directly to the Lenders, to pay to the Administrative Agent any amount due for
the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.09 and 11.04.

         Nothing contained herein shall be deemed to authorize the
Administrative Agent to authorize or consent to or accept or adopt on behalf of
any Lender any plan of reorganization, arrangement, adjustment or composition
affecting the Obligations or the rights of any Lender or to authorize the
Administrative Agent to vote in respect of the claim of any Lender in any such
proceeding.

         9.11     OTHER AGENTS; ARRANGERS AND MANAGERS. None of the Lenders or
other Persons identified on the facing page or signature pages of this Agreement
as a "syndication agent," "documentation agent," "co-agent," "book manager,"
"lead manager," "arranger," "lead arranger" or "co-arranger" shall have any
right, power, obligation, liability, responsibility or duty under this Agreement
other than, in the case of such Lenders, those applicable to all Lenders as
such. Without limiting the foregoing, none of the Lenders or other Persons so
identified shall have or be deemed to have any fiduciary relationship with any
Lender. Each Lender acknowledges that it has not relied, and will not rely, on
any of the Lenders or other Persons so identified in deciding to enter into this
Agreement or in taking or not taking action hereunder.

                                   ARTICLE X.
                             THE COMPANY'S GUARANTY
                        OF MCKESSON CANADA'S OBLIGATIONS

         10.01    GUARANTY OF THE GUARANTIED OBLIGATIONS. The Company hereby
irrevocably and unconditionally guaranties, as primary obligor and not merely
as surety, the due and punctual payment in full of all Guarantied Obligations
when the same shall become due, whether at stated maturity, by required
prepayment, declaration, acceleration, demand or otherwise (including amounts
that would become due but for the operation of the automatic stay under Section
362(a) of the Bankruptcy Code, 11 U.S.C. Section 362(a)). The term "Guarantied
Obligations" is used herein in its most comprehensive sense and includes:

         (a)      any and all Obligations of McKesson Canada now or hereafter
made, incurred or created, whether absolute or contingent, liquidated or
unliquidated, whether due or not due, and however arising under or in connection
with this Agreement, the Notes and Drafts issued by McKesson Canada and the
other Loan Documents, including those arising under successive borrowing
transactions under this Agreement which shall either continue the Obligations of
McKesson Canada or from time to time renew them after they have been satisfied;
and

         (b)      those expenses set forth in Section 10.08.

         10.02    LIABILITY OF THE COMPANY ABSOLUTE. The Company agrees that its
obligations under this Company Guaranty are irrevocable, absolute, independent
and unconditional and shall not be affected by any circumstance which
constitutes a legal or equitable discharge of a guarantor or surety other than
indefeasible payment in full of the Guarantied Obligations. In furtherance of
the foregoing and without limiting the generality thereof, the Company agrees as
follows:

         (a)      This Company Guaranty is a guaranty of payment when due and
not of collectibility.

         (b)      The Administrative Agent may enforce this Company Guaranty
upon the occurrence of an Event of Default under this Agreement notwithstanding
the existence of any dispute between Lenders and any Borrower with respect to
the existence of such Event of Default.

         (c)      The obligations of the Company under this Company Guaranty are
independent of the obligations of McKesson Canada under the Loan Documents and
the obligations of any other guarantor of the obligations of McKesson Canada
under the Loan Documents, and a separate action or actions may be brought and
prosecuted against the Company whether or not any action is brought against
McKesson Canada or any of such other guarantors and whether or not McKesson
Canada is joined in any such action or actions.

         (d)      The Company's payment of a portion, but not all, of the
Guarantied Obligations shall in no way limit, affect, modify or abridge the
Company's liability for any portion of the Guarantied Obligations that has not
been paid. Without limiting the generality of the foregoing, if the
Administrative Agent is awarded a judgment in any suit brought to enforce the
Company's covenant to pay a portion of the Guarantied Obligations, such judgment
shall not be deemed to

                                       71

<PAGE>

release the Company from its covenant to pay the portion of the Guarantied
Obligations that is not the subject of such suit.

         (e)      Any Agent or any Lender, upon such terms as it deems
appropriate, without notice or demand and without affecting the validity or
enforceability of this Company Guaranty or giving rise to any reduction,
limitation, impairment, discharge or termination of the Company's liability
under this Company Guaranty, from time to time may (i) renew, extend,
accelerate, increase the rate of interest on, or otherwise change the time,
place, manner or terms of payment of the Guarantied Obligations, (ii) settle,
compromise, release or discharge, or accept or refuse any offer of performance
with respect to, or substitutions for, the Guarantied Obligations or any
agreement relating thereto and/or subordinate the payment of the same to the
payment of any other obligations; (iii) request and accept other guaranties of
the Guarantied Obligations and take and hold security for the payment of this
Company Guaranty or the Guarantied Obligations; (iv) release, surrender,
exchange, substitute, compromise, settle, rescind, waive, alter, subordinate or
modify, with or without consideration, any security for payment of the
Guarantied Obligations, any other guaranties of the Guarantied Obligations, or
any other obligation of any Person with respect to the Guarantied Obligations;
(v) enforce and apply any security now or hereafter held by or for the benefit
of the Agents or any Lender in respect of this Company Guaranty or the
Guarantied Obligations and direct the order or manner of sale thereof, or
exercise any other right or remedy that the Agents or the Lenders, or any of
them, may have against any such security, as the Administrative Agent in its
discretion may determine consistent with this Agreement and any applicable
security agreement, including foreclosure on any such security pursuant to one
or more judicial or nonjudicial sales, whether or not every aspect of any such
sale is commercially reasonable, and even though such action operates to impair
or extinguish any right of reimbursement or subrogation or other right or remedy
of the Company against McKesson Canada or any security for the Guarantied
Obligations; and (vi) exercise any other rights available to it under the Loan
Documents. This Section 10.02(e) shall not modify Section 11.01.

         (f)      This Company Guaranty and the obligations of the Company
hereunder shall be valid and enforceable and shall not be subject to any
reduction, limitation, impairment, discharge or termination for any reason
(other than indefeasible payment in full of the Guarantied Obligations),
including without limitation the occurrence of any of the following, whether or
not the Company shall have had notice or knowledge of any of them: (i) any
failure or omission to assert or enforce or agreement or election not to assert
or enforce, or the stay or enjoining, by order of court, by operation of law or
otherwise, of the exercise or enforcement of, any claim or demand or any right,
power or remedy (whether arising under the Loan Documents, at law, in equity or
otherwise) with respect to the Guarantied Obligations or any agreement relating
thereto, or with respect to any other guaranty of or security for the payment of
the Guarantied Obligations; (ii) any rescission, waiver, amendment or
modification of, or any consent to departure from, any of the terms or
provisions (including without limitation provisions relating to events of
default) of this Agreement, any of the other Loan Documents or any agreement or
instrument executed pursuant thereto, or of any other guaranty or security for
the Guarantied Obligations, in each case whether or not in accordance with the
terms of this Agreement or such Loan Document or any agreement relating to such
other guaranty or security; (iii) the Guarantied Obligations, or any agreement
relating thereto, at any time being found to be illegal, invalid or
unenforceable in any respect; (iv) the application of payments received from any
source (other

                                       72

<PAGE>

than payments received pursuant to the other Loan Documents or from the proceeds
of any security for the Guarantied Obligations, except to the extent such
security also serves as collateral for indebtedness other than the Guarantied
Obligations) to the payment of indebtedness other than the Guarantied
Obligations, even though the Agents or the Lenders, or any of them, might have
elected to apply such payment to any part or all of the Guarantied Obligations;
(v) any Lender's or Agent's consent to the change, reorganization or termination
of the corporate structure or existence of the Company or any of its
Subsidiaries and to any corresponding restructuring of the Guarantied
Obligations; (vi) any failure to perfect or continue perfection of a security
interest in any collateral which secures any of the Guarantied Obligations;
(vii) any defenses, set-offs or counterclaims which McKesson Canada may allege
or assert against any Agent or any Lender in respect of the Guarantied
Obligations, including but not limited to failure of consideration, breach of
warranty, payment, statute of frauds, statute of limitations, accord and
satisfaction and usury; and (viii) any other act or thing or omission, or delay
to do any other act or thing, which may or might in any manner or to any extent
vary the risk of the Company as an obligor in respect of the Guarantied
Obligations.

         10.03    WAIVERS BY THE COMPANY. The Company hereby waives with respect
to the Guarantied Obligations, for the benefit of the Lenders and the Agents:

         (a)      any right to require any Agent or any Lender, as a condition
of payment or performance by the Company, to (i) proceed against McKesson
Canada, any other guarantor of the Guarantied Obligations or any other Person,
(ii) proceed against or exhaust any security held from McKesson Canada, any
other guarantor of the Guarantied Obligations or any other Person, (iii) proceed
against or have resort to any balance of any deposit account or credit on the
books of any Agent or any Lender in favor of McKesson Canada or any other
Person, or (iv) pursue any other remedy in the power of any Agent or any Lender
whatsoever;

         (b)      any defense arising by reason of the incapacity, lack of
authority or any disability or other defense of McKesson Canada including,
without limitation, any defense based on or arising out of the lack of validity
or the unenforceability of the Guarantied Obligations or any agreement or
instrument relating thereto or by reason of the cessation of the liability of
McKesson Canada from any cause other than indefeasible payment in full of the
Guarantied Obligations;

         (c)      any defense based upon any statute or rule of law which
provides that the obligation of a surety must be neither larger in amount nor in
other respects more burdensome than that of the principal;

         (d)      any defense based upon any Agent's or any Lender's errors or
omissions in the administration of the Guarantied Obligations, except behavior
which amounts to bad faith;

         (e)      (i) any principles or provisions of law, statutory or
otherwise, which are or might be in conflict with the terms of this Guaranty and
any legal or equitable discharge of the Company's obligations hereunder, (ii)
the benefit of any statute of limitations affecting the Company's liability
hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments
and counterclaims, and (iv) promptness, diligence and any requirement that any
Agent or any

                                       73

<PAGE>

Lender protect, secure, perfect or insure any security interest or lien or any
property subject thereto;

         (f)      notices, demands, presentments, protests, notices of protest,
notices of dishonor and notices of any action or inaction, including acceptance
of this Guaranty, notices of default under this Agreement or any agreement or
instrument related thereto, notices of any renewal, extension or modification of
the Guarantied Obligations or any agreement related thereto, notices of any
extension of credit to McKesson Canada and notices of any of the matters
referred to in Section 10.02 and any right to consent to any thereof; and

         (g)      any defenses or benefits that may be derived from or afforded
by law which limit the liability of or exonerate guarantors or sureties, or
which may conflict with the terms of this Company Guaranty, including without
limitation, in accordance with Section 2856 of the California Civil Code, the
provisions of California Civil Code Sections 2787-2855, inclusive, 2899 and
3433.

         10.04    PAYMENT BY THE COMPANY; APPLICATION OF PAYMENTS. The Company
hereby agrees, in furtherance of the foregoing and not in limitation of any
other right which the Administrative Agent or any other Person may have at law
or in equity against the Company by virtue hereof, that upon the failure of
McKesson Canada to pay any of the Guarantied Obligations when and as the same
shall become due, whether at stated maturity, by required prepayment,
declaration, acceleration, demand or otherwise (including amounts that would
become due but for the operation of the automatic stay under Section 362(a) of
the Bankruptcy Code, 11 U.S.C. Section 362(a)), the Company will upon demand
pay, or cause to be paid, in cash, to the Agent for the ratable benefit of the
Lenders holding the Guarantied Obligations, an amount equal to the sum of the
unpaid principal amount of all Guarantied Obligations then due as aforesaid,
accrued and unpaid interest on such Guarantied Obligations (including, without
limitation, interest which, but for the filing of a petition in bankruptcy with
respect to McKesson Canada, would have accrued on such Guarantied Obligations,
whether or not a claim is allowed against McKesson Canada for such interest in
any such bankruptcy proceeding) and all other Guarantied Obligations then owed
to the Administrative Agent and/or the Lenders as aforesaid. All such payments
shall be applied promptly from time to time by the Administrative Agent:

                  First, to the payment of the costs and expenses of any
         collection or other realization under this Company Guaranty, including
         reasonable compensation to the Administrative Agent and its agents and
         counsel, and all expenses, liabilities and advances made or incurred by
         the Administrative Agent in connection therewith;

                  Second, to the payment of all other Guarantied Obligations to
         each Lender holding Guarantied Obligations its applicable share as
         provided in this Agreement; and

                  Third, after payment in full of all Guarantied Obligations, to
         the payment to the Company, or its successors or assigns, or to
         whosoever may be lawfully entitled to receive the same or as a court of
         competent jurisdiction may direct, of any surplus then remaining from
         such payments.

         10.05    GUARANTOR'S RIGHTS OF SUBROGATION, CONTRIBUTION, ETC. Until
the Guarantied Obligations shall have been indefeasibly paid in full and the
Commitments shall have terminated, the Company shall withhold exercise of (a)
any claim, right or remedy, direct or indirect, the Company now has or may
hereafter have against McKesson Canada or any of its assets in connection with
this Company Guaranty or the performance by the Company of its obligations
hereunder, in each case whether such claim, right or remedy arises in equity,
under contract, by statute (including without limitation under California Civil
Code Section 2847, 2848 or 2849), under common law or otherwise and including
without limitation (i) any right of subrogation, reimbursement or
indemnification that the Company now has or may hereafter have against McKesson
Canada, (ii) any right to enforce, or to participate in, any claim, right or
remedy that any Agent or any Lender now has or may hereafter have against
McKesson Canada, and (iii) any benefit of, and any right to participate in, any
collateral or security now or hereafter held by any Agent or any Lender, and (b)
any right of contribution the Company may have against any other guarantor of
the Guarantied Obligations (including without limitation any such right of
contribution under California Civil Code Section 2848). The Company further
agrees that, to the extent the agreement to withhold the exercise of its rights
of subrogation, reimbursement, indemnification and contribution as set forth
herein is found by a court of competent jurisdiction to be void or voidable for
any reason, any rights of subrogation, reimbursement or indemnification the
Company may have against McKesson Canada or against any collateral or security,
and any rights of contribution the Company may have against any such other
guarantor, shall be junior and subordinate to any rights any Agent or any Lender
may have against McKesson Canada, to all right, title and interest any Agent or
any Lender may have in any such collateral or security, and to any right any
Agent or any Lender may have against such other guarantor. Each Agent, on behalf
of Lenders, may use, sell or dispose of any item of collateral or security as it
sees fit without regard to any subrogation rights the Company may have, and upon
any such disposition or sale any rights of subrogation against such collateral
the Company may have shall terminate. If any amount shall be paid to the Company
on account of any such subrogation, reimbursement or indemnification rights at
any time when all Guarantied Obligations shall not have been paid in full, such
amount shall be held in trust for the Administrative Agent on behalf of the
Lenders and shall forthwith be paid over to the Administrative Agent for the
benefit of the Lenders to be credited and applied against the Guarantied
Obligations, whether matured or unmatured, in accordance with the terms hereof.

         10.06    SUBORDINATION OF OTHER OBLIGATIONS. Any indebtedness of
McKesson Canada now or hereafter held by the Company is hereby subordinated in
right of payment to the Guarantied Obligations, and any such indebtedness of
McKesson Canada to the Company collected or received by the Company after an
Event of Default has occurred and is continuing shall be held in trust for the
Administrative Agent on behalf of the Lenders and shall forthwith be paid over
to the Administrative Agent for the benefit of the Lenders to be credited and
applied against the Guarantied Obligations but without affecting, impairing or
limiting in any manner the liability of the Company under any other provision of
this Guaranty.

         10.07    REAL PROPERTY SECURITY. The Company agrees that, if all or a
portion of the Guarantied Obligations or any other guaranty of all or a portion
of the Guarantied Obligations are at any time secured by a deed of trust or
mortgage covering interests in real property, the Administrative Agent or its
designee, in its sole discretion, without notice or demand and without affecting
the liability of the Company, may foreclose, pursuant to the terms of the Loan

                                       75

<PAGE>

Documents or otherwise, on any such deed of trust or mortgage and the property
described therein by nonjudicial or other sale. Without limiting any of the
waivers contained elsewhere herein, the Company hereby waives any defense to
liability arising by reason of the exercise by the Lenders or the Administrative
Agent, or any of them, of any right or remedy contained in any such deed of
trust or mortgage or any of the other Loan Documents. The Company waives all
rights and defenses arising out of an election of remedies by the Lenders or the
Administrative Agent, even though the election of remedies, such as a
nonjudicial foreclosure with respect to security for a Guarantied Obligation,
has destroyed the Company's rights of subrogation and reimbursement against
McKesson Canada by the operation of Section 580d of the California Code of Civil
Procedure or otherwise.

         10.08    EXPENSES. The Company agrees to pay, or cause to be paid, on
demand, and to save the Administrative Agent and the Lenders harmless against
liability for, any and all reasonable costs and expenses (including fees and
disbursements of counsel and allocated costs of internal counsel) incurred or
expended by the Administrative Agent or any Lender in connection with the
enforcement of or preservation of any rights under this Company Guaranty.

         10.09    CONTINUING GUARANTY; TERMINATION OF GUARANTY. This Company
Guaranty is a continuing guaranty and shall remain in effect until all of the
Guarantied Obligations shall have been indefeasibly paid in full and the
Commitments shall have terminated. The Company hereby irrevocably waives any
right (including without limitation any such right arising under California
Civil Code Section 2815) to revoke this Company Guaranty as to future
transactions giving rise to any Guarantied Obligations.

         10.10    AUTHORITY OF THE COMPANY OR MCKESSON CANADA. It is not
necessary for any Lender or any Agent to inquire into the capacity or powers of
McKesson Canada or the officers, directors or any agents acting or purporting to
act on behalf of any of them.

         10.11    FINANCIAL CONDITION OF MCKESSON CANADA. Any extensions of
credit may be granted to McKesson Canada or continued from time to time without
notice to or authorization from the Company regardless of the financial or other
condition of McKesson Canada at the time of any such grant or continuation. No
Lender or Agent shall have any obligation to disclose or discuss with the
Company their assessment, or the Company's assessment, of the financial
condition of McKesson Canada. The Company has adequate means to obtain
information from McKesson Canada on a continuing basis concerning the financial
condition of McKesson Canada and its ability to perform its obligations under
the Loan Documents, and the Company assumes the responsibility for being and
keeping informed of the financial condition of McKesson Canada and of all
circumstances bearing upon the risk of nonpayment of the Guarantied Obligations.
The Company hereby waives and relinquishes any duty on the part of any Agent or
any Lender to disclose any matter, fact or thing relating to the business,
operations or conditions of McKesson Canada now known or hereafter known by any
Agent or any Lender.

         10.12    RIGHTS CUMULATIVE. The rights, powers and remedies given to
the Lenders and the Agents by this Company Guaranty are cumulative and shall be
in addition to and independent of all rights, powers and remedies given to any
Lender and any Agent by virtue of any statute or rule of law or in any of the
other Loan Documents or any agreement between the Company and any Lender and/or
any Agent or between McKesson Canada and any Lender and/or any Agent.

                                       76

<PAGE>

Any forbearance or failure to exercise, and any delay by any Lender or any Agent
in exercising, any right, power or remedy hereunder shall not impair any such
right, power or remedy or be construed to be a waiver thereof, nor shall it
preclude the further exercise of any such right, power or remedy.

         10.13    BANKRUPTCY; POST-PETITION INTEREST; REINSTATEMENT OF GUARANTY.
(a) So long as any Guarantied Obligations remain outstanding, the Company shall
not, without the prior written consent of the Administrative Agent in accordance
with the terms of this Agreement, commence or join with any other Person in
commencing any bankruptcy, reorganization or insolvency proceedings of or
against McKesson Canada. The obligations of the Company under this Company
Guaranty shall not be reduced, limited, impaired, discharged, deferred,
suspended or terminated by any proceeding, voluntary or involuntary, involving
the bankruptcy, insolvency, receivership, reorganization, liquidation or
arrangement of McKesson Canada or by any defense which McKesson Canada may have
by reason of the order, decree or decision of any court or administrative body
resulting from any such proceeding.

         (b)      The Company acknowledges and agrees that any interest on any
portion of the Guarantied Obligations which accrues after the commencement of
any proceeding referred to in clause (a) above (or, if interest on any portion
of the Guarantied Obligations ceases to accrue by operation of law by reason of
the commencement of said proceeding, such interest as would have accrued on such
portion of the Guarantied Obligations if said proceedings had not been
commenced) shall be included in the Guarantied Obligations because it is the
intention of the Company and the Administrative Agent that the Guarantied
Obligations which are guarantied by the Company pursuant to this Guaranty should
be determined without regard to any rule of law or order which may relieve
McKesson Canada of any portion of such Guarantied Obligations. The Company will
permit any trustee in bankruptcy, receiver, debtor in possession, assignee for
the benefit of creditors or similar person to pay the Administrative Agent, or
allow the claim of the Administrative Agent in respect of, any such interest
accruing after the date on which such proceeding is commenced.

         (c)      In the event that all or any portion of the Guarantied
Obligations are paid by McKesson Canada, the obligations of the Company
hereunder shall continue and remain in full force and effect or be reinstated,
as the case may be, in the event that all or any part of such payment(s) are
rescinded or recovered directly or indirectly from any Agent or any Lender as a
preference, fraudulent transfer or otherwise, and any such payments which are so
rescinded or recovered shall constitute Guarantied Obligations for all purposes
under this Company Guaranty.

                                   ARTICLE XI.
                                  MISCELLANEOUS

         11.01    AMENDMENTS, ETC. No amendment or waiver of any provision of
this Agreement or any other Loan Document, and no consent to any departure by
the Company or any other Loan Party therefrom, shall be effective unless in
writing signed by the Required Lenders and the Company or the applicable Loan
Party, as the case may be, and acknowledged by the Administrative Agent, and
each such waiver or consent shall be effective only in the specific

                                       77

<PAGE>

instance and for the specific purpose for which given; provided, however, that
no such amendment, waiver or consent shall:

each Lender;

         (b)      extend or increase the Commitment of any Lender (or reinstate
any Commitment terminated pursuant to Section 8.02) or increase or extend the
obligation of any Lender to accept Drafts except as permitted by Section 2.15,
in each case without the written consent of such Lender;

         (c)      postpone any date fixed by this Agreement or any other Loan
Document for any payment of principal, interest, fees or other amounts due to
the Lenders (or any of them) hereunder (including a decrease in any amount
payable in respect of the Bankers' Acceptance Facility) or under any other Loan
Document without the written consent of each Lender directly affected thereby;

         (d)      reduce the principal of, or the rate of interest specified
herein on, any Loan or L/C Borrowing, or (subject to clause (v) of the second
proviso to this Section 11.01) any fees or other amounts payable hereunder or
under any other Loan Document without the written consent of each Lender
directly affected thereby; provided, however, that only the consent of the
Required Lenders shall be necessary to amend the definition of "Default Rate" or
to waive any obligation of the Borrowers to pay interest at the Default Rate;

         (e)      change Section 2.13 or Section 8.03 in a manner that would
alter the pro rata sharing of payments required thereby without the written
consent of each Lender;

         (f)      change any provision of this Section 11.01 or the definition
of "Required Lenders" or any other provision hereof specifying the number or
percentage of Lenders required to amend, waive or otherwise modify any rights
hereunder or make any determination or grant any consent hereunder, without the
written consent of each Lender; or

         (g)      release the Company from the Company Guaranty without the
written consent of each Lender;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the L/C Issuer in addition to the Lenders required above,
affect the rights or duties of the L/C Issuer under this Agreement or any Letter
of Credit Application relating to any Letter of Credit issued or to be issued by
it; (ii) no amendment, waiver or consent shall, unless in writing and signed by
the Canadian Administrative Agent in addition to the Lenders required above,
affect the rights or duties of the Canadian Administrative Agent under this
Agreement; (iii) no amendment, waiver or consent shall, unless in writing and
signed by the Administrative Agent in addition to the Lenders required above,
affect the rights or duties of the Administrative Agent under this Agreement or
any other Loan Document; (iv) Section 11.07(h) may not be amended, waived or
otherwise modified without the consent of each Granting Lender all or any part
of whose Loans are being funded by an SPC at the time of such amendment, waiver
or other modification; and (v) the Fee Letter may be amended, or rights or
privileges thereunder waived, only in a writing executed by the parties thereto.
Notwithstanding anything to the contrary

                                       78

<PAGE>

herein, no Defaulting Lender shall have any right to approve or disapprove any
amendment, waiver or consent hereunder, except that the Commitment of such
Lender may not be increased or extended without the consent of such Lender.

         11.02    NOTICES AND OTHER COMMUNICATIONS; FACSIMILE COPIES.

         (a)      General. Unless otherwise expressly provided herein, all
notices and other communications provided for hereunder shall be in writing

faxed or delivered to the applicable address, facsimile number or (subject to
Section 11.02(c)) electronic mail address, and all notices and other
communications expressly permitted hereunder to be given by telephone shall be
made to the applicable telephone number, as follows:

                  (i)      if to the Company, the Administrative Agent, the L/C
         Issuer or the Canadian Administrative Agent, to the address, facsimile
         number, electronic mail address or telephone number specified for such
         Person on Schedule 11.02 or to such other address, facsimile number,
         electronic mail address or telephone number as shall be designated by
         such party in a notice to the other parties; and

                  (ii)     if to any other Lender, to the address, facsimile
         number, electronic mail address or telephone number specified in its
         Administrative Questionnaire or to such other address, facsimile
         number, electronic mail address or telephone number as shall be
         designated by such party in a notice to the Company, the Administrative
         Agent, the L/C Issuer and the Canadian Administrative Agent.

(ii) (A) if delivered by hand or by courier, when signed for by or on behalf of
the relevant party hereto; (B) if delivered by mail, four Business Days after
deposit in the mails, postage prepaid; (C) if delivered by facsimile, when sent
and receipt has been confirmed by telephone; and (D) if delivered by electronic

when delivered; provided, however, that notices and other communications to the
Administrative Agent, the L/C Issuer and the Canadian Administrative Agent
pursuant to Article II shall not be effective until actually received by such
Person. In no event shall a voicemail message be effective as a notice,
communication or confirmation hereunder.

         (b)      Effectiveness of Facsimile Documents and Signatures. Loan
Documents may be transmitted and/or signed by facsimile. The effectiveness of
any such documents and signatures shall, subject to applicable Law, have the
same force and effect as manually-signed originals and shall be binding on all
Loan Parties, the Agents and the Lenders. An Agent may also require that any
such documents and signatures be confirmed by a manually-signed original

shall not limit the effectiveness of any facsimile document or signature.

         (c)      Limited Use of Electronic Mail. Electronic mail and Internet
and intranet websites may be used only to distribute routine communications,
such as financial statements

                                       79

<PAGE>

and other information as provided in Section 6.02, and to distribute Loan
Documents for execution by the parties thereto, and may not be used for any
other purpose.

         (d)      Reliance by Agents and Lenders. Each Agent and Lender shall be
entitled to rely and act upon any notices (including telephonic Committed Loan
Notices and Drawing Notices) purportedly given by or on behalf of the Company or
McKesson Canada which such Agent or Lender believes in good faith to have been
given by a duly authorized officer or other person authorized to borrow on
behalf of the Applicable Borrower even if (i) such notices were not made in a
manner specified herein, were incomplete or were not preceded or followed by any
other form of notice specified herein, or (ii) the terms thereof, as understood
by the recipient, varied from any confirmation thereof. Each Borrower shall
indemnify each Agent-Related Person and each Lender from all losses, costs,
expenses and liabilities resulting from the reliance by such Person on each
notice purportedly given by or on behalf of such Borrower. All telephonic
notices to and other communications with an Agent may be recorded by such Agent,
and each of the parties hereto hereby consents to such recording.

         11.03    NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or
the Agents to exercise, and no delay by any such Person in exercising, any
right, remedy, power or privilege hereunder shall operate as a waiver thereof;
nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

         11.04    ATTORNEY COSTS, EXPENSES AND TAXES. The Borrowers agree,
jointly and severally, (a) to pay or reimburse the Agents for all costs and
expenses incurred in connection with the development, preparation, negotiation
and execution of this Agreement and the other Loan Documents and any amendment,
waiver, consent or other modification of the provisions hereof and thereof
(whether or not the transactions contemplated hereby or thereby are
consummated), and the consummation and administration of the transactions
contemplated hereby and thereby, including all Attorney Costs, and (b) to pay or
reimburse the Agents and each Lender for all costs and expenses incurred in
connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies under this Agreement or the other Loan Documents (including
all such costs and expenses incurred during any "workout" or restructuring in
respect of the Obligations and during any legal proceeding, including any
proceeding under any Debtor Relief Law), including all Attorney Costs. The
foregoing costs and expenses shall include all search, filing, recording, title
insurance and appraisal charges and fees and taxes related thereto, and other
out-of-pocket expenses incurred by the Agents and the cost of independent public
accountants and other outside experts retained by the Agents or any Lender. All
amounts due under this Section 11.04 shall be payable within 20 Business Days
after demand therefor. The agreements in this Section 11.04 shall survive the
termination of the Aggregate Commitments and repayment of all other Obligations.

         11.05    INDEMNIFICATION BY THE BORROWERS. Whether or not the
transactions contemplated hereby are consummated, the Borrowers shall jointly
and severally indemnify and hold harmless each Agent-Related Person, each Lender
and their respective Affiliates, directors, officers, employees, counsel, agents
and attorneys-in-fact (collectively the "Indemnitees") from

                                       80

<PAGE>

and against any and all liabilities, obligations, losses, damages, penalties,
claims, demands, actions, judgments, suits, costs, expenses and disbursements
(including Attorney Costs) of any kind or nature whatsoever which may at any
time be imposed on, incurred by or asserted against any such Indemnitee in any
way relating to or arising out of or in connection with (a) the execution,
delivery, enforcement, performance or administration of any Loan Document or any
other agreement, letter or instrument delivered in connection with the
transactions contemplated thereby or the consummation of the transactions
contemplated thereby, (b) any Commitment, Loan or Letter of Credit or the use or
proposed use of the proceeds therefrom (including any refusal by the L/C Issuer
to honor a demand for payment under a Letter of Credit if the documents
presented in connection with such demand do not strictly comply with the terms
of such Letter of Credit), or related to any Canadian Dollar transactions or (c)
any actual or prospective claim, litigation, investigation or proceeding
relating to any of the foregoing, whether based on contract, tort or any other
theory (including any investigation of, preparation for, or defense of any
pending or threatened claim, investigation, litigation or proceeding) and
regardless of whether any Indemnitee is a party thereto (all the foregoing,
collectively, the "Indemnified Liabilities"); provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such liabilities,
obligations, losses, damages, penalties, claims, demands, actions, judgments,
suits, costs, expenses or disbursements which (i) are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of such Indemnitee or (ii) result
from claims by a Borrower against such Indemnitee that are successful on the
merits as determined by a court of competent jurisdiction. No Indemnitee shall
be liable for any damages arising from the use by others of any information or
other materials obtained through IntraLinks or other similar information
transmission systems in connection with this Agreement, nor shall any Indemnitee
have any liability for any indirect or consequential damages relating to this
Agreement or any other Loan Document or arising out of its activities in
connection herewith or therewith (whether before or after the Closing Date). All
amounts due under this Section 11.05 shall be payable within 20 Business Days
after demand therefor. The agreements in this Section 11.05 shall survive the
resignation of the Administrative Agent, the Canadian Administrative Agent or
the L/C Issuer, the replacement of any Lender, the termination of the Aggregate
Commitments and the repayment, satisfaction or discharge of all the other
Obligations.

         11.06    PAYMENTS SET ASIDE. To the extent that any payment by or on
behalf of a Borrower is made to either Agent or any Lender, or either Agent or
any Lender exercises its right of set-off, and such payment or the proceeds of
such set-off or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any
settlement entered into by an Agent or such Lender in its discretion) to be
repaid to a trustee, receiver or any other party, in connection with any
proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of
such recovery, the obligation or part thereof originally intended to be
satisfied shall be revived and continued in full force and effect as if such
payment had not been made or such set-off had not occurred, and (b) each Lender
severally agrees to pay to the Applicable Agent upon demand its applicable share
of any amount so recovered from or repaid by such Agent, plus interest thereon
from the date of such demand to the date such payment is made at a rate per
annum equal to (A) in the case of Domestic Loans and L/C Credit Extensions, the
Federal Funds Rate from time to time in effect and (B) in the case of Canadian
Loans and Bankers' Acceptance Credit Extensions, the Overnight Canadian Rate
from time to time in effect.

         11.07    SUCCESSORS AND ASSIGNS.

         (a)      The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that the Borrowers may not assign or otherwise
transfer any of their rights or obligations hereunder without the prior written
consent of each Lender and no Lender may assign or otherwise transfer any of its
rights or obligations hereunder except (i) to an Eligible Assignee in accordance
with the provisions of Section 11.07(b), (ii) by way of participation in
accordance with the provisions of Section 11.07(d), (iii) by way of pledge or
assignment of a security interest subject to the restrictions of Sections
11.07(f) and (i), or (iv) to an SPC in accordance with the provisions of Section
11.07(h) (and any other attempted assignment or transfer by any party hereto
shall be null and void). Nothing in this Agreement, expressed or implied, shall
be construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby, Participants to the extent
provided in Section 11.07(d) and, to the extent expressly contemplated hereby,
the Indemnitees) any legal or equitable right, remedy or claim under or by
reason of this Agreement.

         (b)      Any Lender may at any time assign to one or more Eligible
Assignees all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitment and the Loans (including for
purposes of this Section 11.07(b), participations in L/C Obligations) at the
time owing to it); provided that (i) except in the case of an assignment of the
entire remaining amount of the assigning Lender's Commitment and the Loans at
the time owing to it or in the case of an assignment to a Lender or an Affiliate
of a Lender, the aggregate amount of the Commitment (which for this purpose
includes Loans outstanding thereunder) subject to each such assignment,
determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to the Administrative Agent or, if "Trade Date" is
specified in the Assignment and Assumption, as of the Trade Date, shall not be
less than $5,000,000 unless each of the Administrative Agent and, so long as no
Event of Default has occurred and is continuing, the Company otherwise consents
(each such consent not to be unreasonably withheld or delayed); (ii) each
partial assignment shall be made as an assignment of a proportionate part of all
the assigning Lender's rights and obligations under this Agreement with respect
to the Loans or the Commitment assigned, (iii) any assignment of a Commitment
must be approved by the Administrative Agent unless the Person that is the
proposed assignee is itself a Lender (whether or not the proposed assignee would
otherwise qualify as an Eligible Assignee); and (iv) the parties to each
assignment shall execute and deliver to the Administrative Agent an Assignment
and Assumption, together with a processing and recordation fee of $3,500.
Subject to acceptance and recording thereof by the Administrative Agent pursuant
to Section 11.07(c), from and after the effective date specified in each
Assignment and Assumption, the Eligible Assignee thereunder shall be a party to
this Agreement and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Lender under this
Agreement, and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 3.01, 3.04, 3.05, 11.04 and 11.05
with respect to facts and circumstances occurring prior to the effective date of
such assignment). Upon request, each Borrower (at its expense) shall execute and
deliver a Note to the assignee Lender.

                                       82

<PAGE>

Any assignment or transfer by a Lender of rights or obligations under this
Agreement that does not comply with this Section 11.07(b) shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with Section 11.07(d).

         (c)      The Administrative Agent, acting solely for this purpose as an
agent of the Borrowers, shall maintain at the Administrative Agent's Office a
copy of each Assignment and Assumption delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amounts of the Loans and L/C Obligations owing to, each Lender
pursuant to the terms hereof from time to time (the "Register"). The entries in
the Register shall be conclusive, and the Borrowers, the Administrative Agent
and the Lenders may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Company and any Lender, at any reasonable time
and from time to time upon reasonable prior notice.

         (d)      In addition to sales of Canadian Participations by Canadian
Lenders pursuant to Section 2.01(b)(ii), any Lender may at any time, without the
consent of, or notice to, the Administrative Agent, sell participations to any
Person (other than a natural person or either Borrower or any of the Borrowers'
Affiliates or Subsidiaries) (each, a "Participant") in all or a portion of such
Lender's rights and/or obligations under this Agreement (including all or a
portion of its Commitment and/or the Loans (including such Lender's
participations in L/C Obligations) owing to it); provided that (i) unless a
Default or Event of Default has occurred and is continuing, the Company shall
have approved the sale of participations to such Person (such approval not to be
unreasonably withheld or delayed); (ii) no participations in Canadian Loans or
Bankers' Acceptances shall be sold to any Person that is not a Canadian
Resident; (iii) such Lender's obligations under this Agreement shall remain
unchanged; (iv) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations; and (v) the Borrowers, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement; provided further that clauses (i) through (v)
of the foregoing proviso are not applicable to Canadian Participations. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any
amendment, waiver or other modification described in the first proviso to
Section 11.01 that directly affects such Participant. Subject to Section
11.07(e), the Borrowers agree that each Participant shall be entitled to the
benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to Section 11.07(b).
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 11.09 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.13 as though it were a Lender.

         (e)      A Participant shall not be entitled to receive any greater
payment under Section 3.01 or 3.04 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Company's prior written consent. A Participant that would be a Foreign Lender if
it were a Lender shall not be entitled to the benefits of Section 3.01 unless
the Company is

                                       83

<PAGE>

notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Company, to comply with Section 11.15 as though
it were a Lender.

         (f)      Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement (including
under its Note, if any) to secure obligations of such Lender, including any
pledge or assignment to secure obligations to a Federal Reserve Bank; provided
that no such pledge or assignment shall release such Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

         (g)      As used herein, the following terms have the following
meanings:

                  "Eligible Assignee" means (a) a Lender; (b) an Affiliate of a
         Lender; and (c) any other Person (other than a natural person) approved
         by (i) the Administrative Agent, and (ii) unless a Default or an Event
         of Default has occurred and is continuing, the Company (each such
         approval not to be unreasonably withheld or delayed); provided that
         notwithstanding the foregoing, (i) "Eligible Assignee" shall not
         include either Borrower or any of the Borrowers' Affiliates or
         Subsidiaries and (ii) in the case of clauses (a) and (b), no such
         Lender or Affiliate shall be an Eligible Assignee for purposes of
         Canadian Loans or Bankers' Acceptances unless such Person is a Canadian
         Resident.

         (h)      Notwithstanding anything to the contrary contained herein, any
Lender (a "Granting Lender") may grant to a special purpose funding vehicle
identified as such in writing from time to time by the Granting Lender to the
Administrative Agent and the Company (an "SPC") the option to provide all or any
part of any Committed Loan that such Granting Lender would otherwise be
obligated to make pursuant to this Agreement; provided that (i) nothing herein
shall constitute a commitment by any SPC to fund any Committed Loan, and (ii) if
an SPC elects not to exercise such option or otherwise fails to make all or any
part of such Committed Loan, the Granting Lender shall be obligated to make such
Committed Loan pursuant to the terms hereof; provided further that no such grant
to an SPC shall impose Taxes or Other Taxes on either Borrower. Each party
hereto hereby agrees that (i) neither the grant to any SPC nor the exercise by
any SPC of such option shall increase the costs or expenses or otherwise
increase or change the obligations of the Company under this Agreement
(including its obligations under Section 3.04), (ii) no SPC shall be liable for
any indemnity or similar payment obligation under this Agreement for which a
Lender would be liable, and (iii) the Granting Lender shall for all purposes,
including the approval of any amendment, waiver or other modification of any
provision of any Loan Document, remain the lender of record hereunder. The
making of a Committed Loan by an SPC hereunder shall utilize the Commitment of
the Granting Lender to the same extent, and as if, such Committed Loan were made
by such Granting Lender. In furtherance of the foregoing, each party hereto
hereby agrees (which agreement shall survive the termination of this Agreement)
that, prior to the date that is one year and one day after the payment in full
of all outstanding commercial paper or other senior debt of any SPC, it will not
institute against, or join any other Person in instituting against, such SPC any
bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding
under the laws of the United States or any State thereof. Notwithstanding
anything to the contrary contained herein, any SPC may (i) with notice to, but
without prior consent of the Company and the Administrative Agent and without
paying any processing fee therefor, assign all or any portion

                                       84

<PAGE>

of its right to receive payment with respect to any Committed Loan to the
Granting Lender and (ii) disclose on a confidential basis any non-public
information relating to its funding of Committed Loans to any rating agency,
commercial paper dealer or provider of any surety or Guarantee or credit or
liquidity enhancement to such SPC.

         (i)      Notwithstanding anything to the contrary contained herein, any
Lender that is a Fund may create a security interest in all or any portion of
the Loans owing to it and the Note, if any, held by it to the trustee for
holders of obligations owed, or securities issued, by such Fund as security for
such obligations or securities, provided that unless and until such trustee
actually becomes a Lender in compliance with the other provisions of this
Section 11.07, (i) no such pledge shall release the pledging Lender from any of
its obligations under the Loan Documents and (ii) such trustee shall not be
entitled to exercise any of the rights of a Lender under the Loan Documents even
though such trustee may have acquired ownership rights with respect to the
pledged interest through foreclosure or otherwise. For purposes of this Section
11.07(i), "Fund" means any Person (other than a natural person) that is (or will
be) engaged in making, purchasing, holding or otherwise investing in commercial
loans and similar extensions of credit in the ordinary course of its business.

         (j)      Notwithstanding anything to the contrary contained herein, if
at any time Wachovia Bank, National Association assigns all of its Commitment
and Loans pursuant to Section 11.07(b), Wachovia Bank, National Association may,
upon 30 days' notice to the Company and the Lenders, resign as L/C Issuer. In
the event of any such resignation as L/C Issuer, the Company shall be entitled
to appoint from among the Lenders a successor L/C Issuer hereunder; provided,
however, that no failure by the Company to appoint any such successor shall
affect the resignation of Wachovia Bank, National Association as L/C Issuer. In
the event that each Lender selected by the Company as L/C Issuer declines the
appointment, Bank of America shall become the L/C Issuer, without further action
by the Company or the Lenders. If Wachovia Bank, National Association resigns as
L/C Issuer, it shall retain all the rights and obligations of the L/C Issuer
hereunder with respect to all Letters of Credit outstanding as of the effective
date of its resignation as L/C Issuer and all L/C Obligations with respect
thereto (including the right to require the Lenders to make Base Rate Committed
Loans or fund risk participations in Unreimbursed Amounts pursuant to Section
2.03(c)).

         11.08    CONFIDENTIALITY. Each of the Agents and Lenders agrees to
maintain, and to cause its Affiliates (including any Agent-Related Persons) to
maintain, the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its and its Affiliates' directors, officers,
employees and agents, including accountants, legal counsel and other advisors
(it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep
such Information confidential); (b) to the extent requested by any regulatory
authority having jurisdiction over such Person; (c) to the extent required by
applicable laws or regulations or by any subpoena or similar legal process; (d)
to any other party to this Agreement; (e) to the extent reasonably required, in
connection with the exercise of any remedies hereunder or any suit, action or
proceeding relating to this Agreement or the enforcement of rights hereunder;
(f) subject to an agreement containing provisions substantially the same as
those of this Section 11.08, to (i) any Eligible Assignee of or Participant in,
or any prospective Eligible Assignee of or Participant in, any of its rights or
obligations under this Agreement or (ii) any direct or indirect contractual

                                       85

<PAGE>

counterparty or prospective counterparty (or such contractual counterparty's or
prospective counterparty's professional advisor) to any credit derivative
transaction relating to obligations of the Loan Parties under the Loan
Documents; (g) with the consent of the Company; or (h) to the extent such
Information (i) becomes publicly available other than as a result of a breach of
this Section 11.08 or (ii) becomes available to the Administrative Agent or any
Lender on a nonconfidential basis from a source other than the Company;
provided, however, that to the extent permitted by applicable law or regulation,
each of the Agents and Lenders agrees to notify the Company prior to (if
reasonably practicable) or concurrently with its disclosure of such information
to any third party pursuant to clauses (c) and (f). In addition, the
Administrative Agent and the Lenders may disclose the existence of this
Agreement and public information about this Agreement to market data collectors,
similar service providers to the lending industry, and service providers to the
Administrative Agent and the Lenders in connection with the administration and
management of this Agreement, the other Loan Documents, the Commitments, and the
Credit Extensions. For the purposes of this Section 11.08, "Information" means
all information received from any Loan Party relating to any Loan Party or its
business, other than any such information that is available to the
Administrative Agent or any Lender on a nonconfidential basis prior to
disclosure by any Loan Party; provided that, in the case of information received
from a Loan Party after the date hereof, such information is clearly identified
at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section 11.08 shall be
considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such
Information as such Person would accord to its own confidential information.

         11.09    SET-OFF. In addition to any rights and remedies of the Lenders
provided by law, upon the occurrence and during the continuance of any Event of
Default, each Lender is authorized at any time and from time to time, without
prior notice to the Borrowers, any such notice being waived by the Borrowers to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Lender to or for the credit or
the account of the respective Loan Parties against any and all Obligations owing
to such Lender hereunder or under any other Loan Document, now or hereafter
existing, irrespective of whether or not the Administrative Agent or such Lender
shall have made demand under this Agreement or any other Loan Document and
although such Obligations may be contingent or unmatured or denominated in a
currency different from that of the applicable deposit or indebtedness. Each
Lender agrees promptly to notify the Borrowers and the Administrative Agent
after any such set-off and application made by such Lender; provided, however,
that the failure to give such notice shall not affect the validity of such
set-off and application.

         11.10    INTEREST RATE LIMITATION. Notwithstanding anything to the
contrary contained in any Loan Document, the interest paid or agreed to be paid
under the Loan Documents shall not exceed the maximum rate of non-usurious
interest permitted by applicable Law (the "Maximum Rate"). If either Agent or
any Lender shall receive interest in an amount that exceeds the Maximum Rate,
the excess interest shall be applied to the principal of the Loans or, if it
exceeds such unpaid principal, refunded to the Applicable Borrower. In
determining whether the interest contracted for, charged, or received by the
Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to
the extent permitted by applicable Law, (a) characterize

                                       86

<PAGE>

any payment that is not principal as an expense, fee, or premium rather than
interest, (b) exclude voluntary prepayments and the effects thereof, and (c)
amortize, prorate, allocate, and spread in equal or unequal parts the total
amount of interest throughout the contemplated term of the Obligations
hereunder.

         11.11    COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         11.12    INTEGRATION. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and thereof and supersedes all prior agreements, written
or oral, on such subject matter. In the event of any conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control; provided that the inclusion of
supplemental rights or remedies in favor of the Agents or the Lenders in any
other Loan Document shall not be deemed a conflict with this Agreement. Each
Loan Document was drafted with the joint participation of the respective parties
thereto and shall be construed neither against nor in favor of any party, but
rather in accordance with the fair meaning thereof.

         11.13    SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made hereunder and in any other Loan Document or
other document delivered pursuant hereto or thereto or in connection herewith or
therewith shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by each Agent
and each Lender, regardless of any investigation made by either Agent or any
Lender or on their behalf and notwithstanding that either Agent or any Lender
may have had notice or knowledge of any Default at the time of any Credit
Extension, and shall continue in full force and effect as long as any Loan or
any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter
of Credit shall remain outstanding.

         11.14    SEVERABILITY. If any provision of this Agreement or the other
Loan Documents is held to be illegal, invalid or unenforceable, (a) the
legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby
and (b) the parties shall endeavor in good faith negotiations to replace the
illegal, invalid or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         11.15    TAX FORMS. (a) (i) Each Lender that is not a "United States
person" within the meaning of Section 7701(a)(30) of the Code (a "Foreign
Lender") shall deliver to the Administrative Agent, prior to receipt of any
payment subject to withholding under the Code (or upon accepting an assignment
of an interest herein), two duly signed completed copies of either IRS Form
W-8BEN or any successor thereto (relating to such Foreign Lender and entitling
it to an exemption from, or reduction of, withholding tax on all payments to be
made to such Foreign Lender by the Company pursuant to this Agreement) or IRS
Form W-8ECI or any successor thereto (relating to all payments to be made to
such Foreign Lender by the Borrowers pursuant to this Agreement) or such other
evidence satisfactory to the Company and the Administrative

                                       87

<PAGE>

Agent that such Foreign Lender is entitled to an exemption from, or reduction
of, U.S. withholding tax, including any exemption pursuant to Section 881(c) of
the Code. Thereafter and from time to time, each such Foreign Lender shall (A)
promptly submit to the Administrative Agent such additional duly completed and
signed copies of one of such forms (or such successor forms as shall be adopted
from time to time by the relevant United States taxing authorities) as may then
be available under then current United States laws and regulations to avoid, or
such evidence as is satisfactory to the Company and the Administrative Agent of
any available exemption from or reduction of, United States withholding taxes in
respect of all payments to be made to such Foreign Lender by the Company
pursuant to this Agreement, (B) promptly notify the Administrative Agent of any
change in circumstances which would modify or render invalid any claimed
exemption or reduction, and (C) take such steps as shall not be materially
disadvantageous to it, in the reasonable judgment of such Lender, and as may be
reasonably necessary (including the re-designation of its Lending Office) to
avoid any requirement of applicable Laws that the Company make any deduction or
withholding for taxes from amounts payable to such Foreign Lender.

         (ii)     Each Foreign Lender, to the extent it does not act or ceases
to act for its own account with respect to any portion of any sums paid or
payable to such Lender under any of the Loan Documents (for example, in the case
of a typical participation by such Lender), shall deliver to the Administrative
Agent on the date when such Foreign Lender ceases to act for its own account
with respect to any portion of any such sums paid or payable, and at such other
times as may be necessary in the determination of the Administrative Agent (in
the reasonable exercise of its discretion), (A) two duly signed completed copies
of the forms or statements required to be provided by such Lender as set forth
above, to establish the portion of any such sums paid or payable with respect to
which such Lender acts for its own account that is not subject to U.S.
withholding tax, and (B) two duly signed completed copies of IRS Form W-8IMY (or
any successor thereto), together with any information such Lender chooses to
transmit with such form, and any other certificate or statement of exemption
required under the Code, to establish that such Lender is not acting for its own
account with respect to a portion of any such sums payable to such Lender.

         (iii)    The Company shall not be required to pay any additional amount
to any Foreign Lender under Section 3.01 (A) with respect to any Taxes required
to be deducted or withheld on the basis of the information, certificates or
statements of exemption such Lender transmits with an IRS Form W-8IMY pursuant
to this Section 11.15(a) or (B) if such Lender shall have failed to satisfy the
foregoing provisions of this Section 11.15(a); provided that if such Lender
shall have satisfied the requirement of this Section 11.15(a) on the date such
Lender became a Lender or ceased to act for its own account with respect to any
payment under any of the Loan Documents, nothing in this Section 11.15(a) shall
relieve the Company of its obligation to pay any amounts pursuant to Section
3.01 in the event that, as a result of any subsequent change in any applicable
law, treaty or governmental rule, regulation or order, or any subsequent change
in the interpretation, administration or application thereof, such Lender is no
longer properly entitled to deliver forms, certificates or other evidence at a
subsequent date establishing the fact that such Lender or other Person for the
account of which such Lender receives any sums payable under any of the Loan
Documents is not subject to withholding or is subject to withholding at a
reduced rate.

                                       88

<PAGE>

         (iv)     The Administrative Agent may, without reduction, withhold any
Taxes required to be deducted and withheld from any payment under any of the
Loan Documents with respect to which the Company is not required to pay
additional amounts under this Section 11.15(a).

         (b)      Upon the request of the Administrative Agent, each Lender that
is a "United States person" within the meaning of Section 7701(a)(30) of the
Code shall deliver to the Administrative Agent two duly signed completed copies
of IRS Form W-9. If such Lender fails to deliver such forms, then the
Administrative Agent may withhold from any interest payment to such Lender an
amount equivalent to the applicable back-up withholding tax imposed by the Code,
without reduction.

         (c)      If any Governmental Authority asserts that the Administrative
Agent did not properly withhold or backup withhold, as the case may be, any tax
or other amount from payments made to or for the account of any Lender, such
Lender shall indemnify the Administrative Agent therefor, including all
penalties and interest, any taxes imposed by any jurisdiction on the amounts
payable to the Administrative Agent under this Section 11.15, and costs and
expenses (including Attorney Costs) of the Administrative Agent. The obligation
of the Lenders under this Section 11.15 shall survive the termination of the
Aggregate Commitments, repayment of all other Obligations hereunder and the
resignation of the Administrative Agent.

         (d)      Each Canadian Lender hereby represents and warrants that it is
a Canadian Resident, and each Canadian Lender agrees that if the foregoing
representation is inaccurate with respect to such Canadian Lender in any
material respect, then the Applicable Borrower shall not be required to pay to
such Canadian Lender any amounts pursuant to Section 3.01 relating to any Taxes
resulting solely from such inaccuracy. If a Borrower is required to pay amounts
to any Canadian Lender pursuant to Section 3.01 (whether by reason of such
Canadian Lender's change of status or otherwise), then such Canadian Lender
shall use reasonable efforts (consistent with legal and regulatory restrictions)
to take such actions as are necessary to minimize such Borrower's obligations
under Article III, if such actions, in the sole judgment of such Canadian
Lender, are not otherwise disadvantageous to such Canadian Lender.

         11.16    REPLACEMENT OF LENDERS.

         Under any circumstances set forth herein providing that the Company
shall have the right to replace a Lender as a party to this Agreement, or if the
Administrative Agent and the Company have mutually determined that a Lender is a
Defaulting Lender, in either case the Company may, upon notice to such Lender
and the Administrative Agent, replace such Lender by causing such Lender to
assign its Commitment (with the assignment fee to be paid by the Company in such
instance) pursuant to Section 11.07(b) to one or more other Lenders or Eligible
Assignees procured by the Company; provided, however, that if the Company elects
to exercise such right with respect to any Lender pursuant to Section 3.06(b),
it shall be obligated to replace all Lenders that have made similar requests for
compensation pursuant to Section 3.01 or 3.04. The Company shall (i) pay in full
all principal, interest, fees and other amounts owing to such Lender through the
date of replacement (including any amounts payable pursuant to Section 3.05),
(ii) provide appropriate assurances and indemnities (which may include letters
of credit) to the L/C Issuer as each may reasonably require with respect to any
continuing

                                       89

<PAGE>

obligation to fund participation interests in any L/C Obligations then
outstanding, and (iii) release such Lender from its obligations under the Loan
Documents. Any Lender being replaced shall execute and deliver an Assignment and
Assumption with respect to such Lender's Commitment and outstanding Loans and
participations in L/C Obligations.

         11.17    GOVERNING LAW.

         (a)      THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, the LAW OF THE STATE OF CALIFORNIA applicable to agreements
made and to be performed entirely within such State; PROVIDED THAT THE AgentS,
THE L/C ISSUER AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL
LAW.

         (b)      ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF
CALIFORNIA OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF SUCH STATE, AND
BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWERS, THE Agents, THE L/C
ISSUER AND EACH LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO
THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWERS, THE Agents, THE
l/c issuer AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY
OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR
PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER
DOCUMENT RELATED THERETO. THE BORROWERS, THE AgentS, THE L/C ISSUER AND EACH
LENDER WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH
MAY BE MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

         (c)      The Borrowers expressly require that this document and all
documents accessory hereto be drawn up in English and each Agent and each
Lender, because of the customer's requirement and by making such documents
available to the customer in the English language, expresses the same
requirement.

         Les Emprunteurs requierent expressement que ce document et tous les
documents qui s'y rapportent soient rediges en langue anglaise et chaque
Mondataire et chaque Banque, a cause de cette exigence du client, exprime la
meme volonte en faisant en sorte que les documents en langue anglaise soient a
la disposition du client.

         11.18    WAIVER OF RIGHT TO TRIAL BY JURY. EACH PARTY TO THIS AGREEMENT
HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION
OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH
OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM
WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH
CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN

                                       90

<PAGE>

CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT
ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT
TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL
COUNTERPART OR A COPY OF THIS SECTION 11.18 WITH ANY COURT AS WRITTEN EVIDENCE
OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL
BY JURY.

         11.19    JUDGMENT. If, for the purposes of obtaining judgment in any
court, it is necessary to convert a sum due hereunder or any other Loan Document
in one currency into another currency, the rate of exchange used shall be that
at which in accordance with normal banking procedures the Administrative Agent
could purchase the first currency with such other currency on the Business Day
preceding that on which final judgment is given. The obligation of a Borrower in
respect of any such sum due from it to the Administrative Agent hereunder or
under the other Loan Documents shall, notwithstanding any judgment in a currency
(the "Judgment Currency") other than that in which such sum is denominated in
accordance with the applicable provisions of this Agreement (the "Agreement
Currency"), be discharged only to the extent that on the Business Day following
receipt by the Administrative Agent of any sum adjudged to be so due in the
Judgment Currency, the Administrative Agent may in accordance with normal
banking procedures purchase the Agreement Currency with the Judgment Currency.
If the amount of the Agreement Currency so purchased is less than the sum
originally due to the Administrative Agent in the Agreement Currency, the
Borrowers agree, as a separate obligation and notwithstanding any such judgment,
jointly and severally, to indemnify the Administrative Agent or the Person to
whom such obligation was owing against such loss. If the amount of the Agreement
currency so purchased is greater than the sum originally due to the
Administrative Agent in such currency, the Administrative Agent agrees to return
the amount of any excess to the Applicable Borrower (or to any other Person who
may be entitled thereto under applicable law).

Part (b).         Indebtedness in Excess of $25,000,000 Secured by Liens.

                  As of August 31, 2002, the Company and its Subsidiaries had an
outstanding debt of approximately $16,186,500 for borrowed money with respect to
the Company's headquarters building at One Post Street in San Francisco,
California (the "Building"). This constitutes 50% of the total amount
outstanding (approximately $32,373,000) under the mortgage on the Building. The
Company's wholly owned subsidiary, Crocker Plaza Company, owns an undivided 50%
interest in the property that is subject to the mortgage and, under the terms of
the mortgage documents, is liable for 50% of the mortgage debt. However, the
related Lien (securing the obligations of both Crocker Plaza Company and the
co-owner) attaches to the entire property and, as a result, the total amount
outstanding under the mortgage is "Indebtedness" of the Company and its
Subsidiaries pursuant to clause (h) of the definition of that term in this
Agreement, notwithstanding that neither the Company nor its Subsidiary is
obligated to pay the 50% portion of the mortgage debt that is owed by the
property's co-owner.
