any Event of Default or event which,  with the giving of notice or lapse of time
or both could constitute an Event of Default,  Lender may elect to make advances
under the Loan in excess of the  Borrowing  Base;  provided  that to the  extent
Lender makes any such advance to Borrower,  any commitment fee charged by Lender
with respect to any such  advance  shall be equal not more than two and one-half

Accounts or otherwise of PHCVA) are  immediately  transferred  into a depository
account  maintained by Lender at Bank One Arizona,  N.A. or First Union National
Bank,  N.A., as determined by Lender in its sole discretion and  communicated to
Borrower (the  "Concentration  Account");  provided  that,  notwithstanding  the
foregoing,  (a) so long as no Event of Default is then  occurring or continuing,
Borrower shall be entitled,  with respect to any funds representing  collections
of  Accounts  or  otherwise  of PHCVA,  to direct the  Lockbox  Bank to promptly
transfer such funds only back to PHCVA for use by PHCVA in its sole  discretion,
provided,  that on the  occurrence  of any  Event  of  Default,  Borrower  shall
immediately  instruct  the  Lockbox  Bank that all  collections  of  Accounts or
otherwise  of PHCVA  shall,  immediately  as of the date of such  notice  to the
Lockbox Bank and during the  continuance  of any such Event of Default  shall be
transferred into the Concentration  Account,  and (b) PHCVA shall be entitled to
receive  collections  of  Accounts  directly  from any of its  Account  Debtors,
provided that PHCVA holds such  collections of Accounts in trust for the benefit
of Lender and immediately remits such collections,  in the form received, to the
Lockbox Bank,  and,  provided  further,  that so long as PHCVA complies with the
requirements  of the foregoing  proviso with respect to  collections of Accounts
received by it  directly,  PHCVA shall not be in breach of the  requirements  of
this Section 2.3."

     (f)  Section 2.8(a) of the Loan Agreement  shall be amended and restated in
          its entirety to read as follows:

          "(a) Subject to Lender's right to cease making  Revolving Credit Loans
               to Borrower  upon or after any Event of Default,  this  Agreement
               shall be in effect until  November 30, 2004,  and this  Agreement
               shall automatically renew itself for one-year periods thereafter,
               unless terminated as provided in this Section 2.8."

     (g)  Section 2.8(c) of the Loan Agreement  shall be amended and restated in
          its entirety to read as follows:

terminate  this  Agreement  prior to November 30, 2004,  provided  that,  at the
effective date of such termination, Borrower shall pay to Lender (in addition to
the then outstanding  principal,  accrued interest and other  Obligations  owing
under  the  terms of this  Agreement  and any  other  Loan  Documents)  as yield
maintenance for the loss of bargain and not as a penalty, an amount equal to the
applicable Termination Fee."

Lender a commitment or other fee in  connection  with the  modifications  to the
Loan Agreement set forth in this Amendment.

     Section 6.  Costs.  Borrower  shall be  responsible  for the payment of all
