At the Closing Date, holders of certificates representing PVAXX Shares that
were  outstanding immediately prior to the Closing Date shall cease to have
any rights  as stockholders of PVAXX, and the stock transfer books of PVAXX
shall be closed with respect to all shares of such common stock outstanding
immediately prior to the Closing Date.  As of the date of execution of this

to  the  provisions  of  Section  1:7,  and  PVAXX  Stock   Certificate  so
surrendered shall be canceled.  Until surrendered as contemplated  by  this

the Closing  Date,  to  represent  only  the  right  to  receive  upon such
surrender  a  certificate representing shares of OAK BROOK Common Stock  or
OAK BROOK Preferred  Stock,  as the case may be, as contemplated by Section
1:7.   If any PVAXX Stock Certificate  shall  have  been  lost,  stolen  or
destroyed, OAK BROOK may, in its discretion and as a condition precedent to
the issuance  of any certificate representing OAK BROOK Common Stock or OAK
BROOK Preferred  Stock, as the case may be, require the owner of such lost,
stolen or destroyed  PVAXX  Stock  Certificate  to  provide  an appropriate
affidavit  and  to deliver a bond (in such sum as OAK BROOK may  reasonably
direct) as indemnity  against  any claim that may be made against OAK BROOK
with respect to such PVAXX Stock Certificate.

(B)  No dividends or other distributions  declared  or made with respect to
OAK BROOK Common Shares or OAK BROOK Preferred Shares,  as the case may be,
with a record date after the Closing Date shall be paid to  the  holder  of
any  un-surrendered  PVAXX  Stock Certificate with respect to the shares of
OAK BROOK represented thereby until such holder surrenders such PVAXX Stock
Certificate in accordance with  this  Section  1:7:3  (at  which  time such
holder shall be entitled to receive all such dividends and distributions).

(C)  OAK  BROOK  shall  not  be  liable  to  any holder or former holder of
preferred or common stock of PVAXX for any shares of OAK BROOK Common Stock
or  OAK  BROOK  Preferred  Stock,  as the case may  be,  (or  dividends  or
distributions with respect thereto),  or for any cash amounts, delivered to
any public official pursuant to any applicable  abandoned property, escheat
or similar law.

minute books are true and correct in all material respects.

     2:1:19 COMPLIANCE WITH ERISA.

Except as set forth in Section 2:1:19 PVAXX has no other benefit plans (the
"Benefit Plans") within  the  meaning  of  the applicable provisions of the
Employee Retirement Income Security Act of 1974,  as amended ("ERISA"), the
Code and other applicable  laws to the best of PVAXX's knowledge.

          2:1:19:1 PROHIBITED TRANSACTIONS.

To the knowledge of PVAXX and all its subsidiaries,  PVAXX  or  any  of its
subsidiaries have not engaged in a transaction in connection with which  it
could  be  subject (either directly or indirectly)  to a material liability
for either a civil penalty assessed pursuant to  Section 502(i) of ERISA or
a tax imposed by Section 4975 of the Code.

          2:1:19:2 PLAN TERMINATION; MATERIAL LIABILITIES.

To the best  of  PVAXX's  knowledge,  there  has  been no termination of an
"employee pension benefit  plan" as defined in ERISA  which  is  subject to
Title IV of ERISA (a "Statutory Plan") or trust created under any Statutory
Plan  that  would  give rise to a material liability to the Pension Benefit
Guaranty  Corporation  ("PBGC")  on  the  part  of  PVAXX  or  any  of  its
subsidiaries.   To the best knowledge of PVAXX and all of its subsidiaries,
all statutory Plans  intended  to  be tax-qualified under Section 401(a) or
403(a) of the Code have complied in  the  past, both in form and operation,
with every provision of the Code, regulation  promulgated pursuant thereto,
and every ruling, notice or announcement issued  by  the  Internal  Revenue
Service  necessary  to  maintain  the  qualified  status of such  Statutory
Plans, except where non compliance would not have a material adverse effect
on PVAXX or any of its subsidiaries. No material liability  to the PBGC has
been or is expected to be incurred with respect to any Statutory  Plan. The
PBGC has not instituted proceedings to terminate any Statutory Plan. To the
best  knowledge  of  PVAXX  and  all  of  its subsidiaries, there exists no
condition  or  set  of  circumstances which presents  a  material  risk  of
termination or partial termination of any Statutory Plan by the PBGC.

          2:1:19:3 ACCUMULATED FUNDING DEFICIENCY.

To  the best of PVAXX's knowledge,  full  payment  has  been  made  of  all
amounts, if any, which are required under the terms of each statutory plan,
ERISA  or  other applicable laws to have been paid as contributions to such
Statutory Plan,  and  no   accumulated  funding  deficiency  (as defined in
Section 302 of ERISA and Section 412 of the Code), whether or  not  waived,
exists with respect to any Statutory Plan.

          2:1:19:4 RELATIONSHIP OF BENEFITS TO PENSION PLAN ASSETS.

To  the  best  of  PVAXX's  knowledge,  the  current  value  of all accrued
benefits,  both  vested  and unvested, under all Statutory Plans  does  not
exceed the current value of  the   assets of such Statutory Plans allocable
to such accrued benefits, except as  disclosed  in the financial statements
described  in Section 2:1:19. For purposes of the  representation  in  this
Section 2:1:19:4,  the  term  "current value" has  the meaning specified in
Section 4062(b)(1)(A) of ERISA,  the term "accrued benefit" has the meaning
specified in Section 3 of ERISA and  "current value" is based upon the same
actuarial assumptions used by OAK BROOK.

          2:1:19:5 EXECUTION OF AGREEMENTS.

To  the  best of PVAXX's knowledge, the  execution  and  delivery  of  this
Agreement  and  the  Transaction  Documents,  and  the  consummation of the
transaction contemplated hereby will not involve any transaction  which  is
subject  to  the prohibitions of Section 406 of ERISA or in connection with
which a tax could be imposed pursuant to Section 4975 of the Code.


          2:1:19:6 FIDUCIARY LIABILITY.

To the best of  PVAXX  and  its subsidiaries' knowledge, there have been no
acts, failures to act, omissions or transactions involving a Statutory Plan
or the assets thereof which could  result  in  imposition  on  PVAXX or its
subsidiaries (whether direct or indirect) of material damages or  liability
in actions brought under Section 502 or Sections 404 through 409 of ERISA.

          2:1:19:7 PENDING CLAIMS.

To  the  best of PVAXX and its subsidiaries knowledge, there are no claims,
pending or  overtly  threatened,  involving any of the Benefit Plans by any
current or former employee (or beneficiary  thereof)  of PVAXX which allege
any material violation of ERISA or the terms of the Benefit  Plans,  nor is
there  any  reasonable  basis  to anticipate any such claims involving such
Benefit Plans which would likely  be  successfully maintained against PVAXX
or any of it subsidiaries.

          2:1:19:8 MULTIEMPLOYER PLANS.

To the best of PVAXX's knowledge, neither  PVAXX  nor any trade or business
(whether  or  not   incorporated)  which together with  PVAXX  or  any  its
subsidiaries would be deemed to be a  "single  employer" within the meaning
of Section 400(b) of ERISA or Subsections 414(b),  (c),  (m)  or (o) of the
Code sponsors, maintains, or contributes to, or has at any time  in the six
year period proceeding the date of this Agreement  sponsored, maintained or
contributed  to,  any  place  (not  exempt  from the  provisions of ERISA),
including, but not limited to, any plan which  is a "multiemployer plan" as
such term is defined in Section 3(37) or 4001(a)(3)  of ERISA.

          2:1:19:9 NO REPORTABLE EVENT.

To the best of PVAXX or any of its subsidiaries'  knowledge, there has been
no "reportable event" (within the meaning of Section  4043(b) of ERISA with
respect to a Statutory Plan) or any "prohibited transaction"  (as such term
is  defined  in Section 406 of ERISA and Section 4975(c) of the Code)  with
respect  to any  of  the  Employee  Plans.  All  reporting  and  disclosure
requirements under Title I of ERISA have been met.

     2:1:20 NO UNDISCLOSED DEFAULTS.

To the best knowledge of PVAXX and any of its subsidiaries, neither PVAXX
or any of its subsidiaries is not in material default with respect to any
obligation, agreement or covenant to be performed by it under any contract
or arrangement of any kind, which default would have a material adverse
effect on PVAXX or any of its subsidiaries.

     3:1:17 COMPLIANCE WITH ERISA.

Each  benefit  plan set forth in Section 3:1:17 of the  Disclosure Schedule
(collectively  the   "Benefit   Plans")  substantially  complies  with  the
applicable provisions of the Employee  Retirement  Income  Security  Act of
1974, as amended ("ERISA"), the Code and other applicable  laws. Except  as
provided  in  Section  3:1:17 of the Disclosure Schedule, all contributions
required to be made to each  Benefit  Plan  under the terms of such Benefit
Plans,  ERISA or other applicable laws have been  timely  made.  Except  as
provided in Section 3:1:17 of the Disclosure Schedule.

          3:1:17:1 PROHIBITED TRANSACTIONS.

To the knowledge  of  OAK BROOK, OAK BROOK has not engaged in a transaction
in  connection  with  which   it  could  be  subject  (either  directly  or
indirectly)  to a material liability  for  either  a civil penalty assessed
pursuant to  Section 502(i) of ERISA or a tax imposed  by  Section  4975 of
the Code.

          3:1:17:2 PLAN TERMINATION; MATERIAL LIABILITIES.

There  has  been  no termination of an "employee pension benefit  plan"  as
defined in ERISA which is subject to Title IV of ERISA (a "Statutory Plan")
or trust created under  any  Statutory  Plan  that  would  give  rise  to a
material liability to the Pension Benefit Guaranty Corporation ("PBGC")  on
the  part  of OAK BROOK.  To the best knowledge of OAK BROOK, all OAK BROOK
statutory Plans intended to be tax-qualified under Section 401(a) or 403(a)
of the Code  have  complied  in  the past, both in form and operation, with
every provision of the Code, regulation  promulgated  pursuant thereto, and
every  ruling,  notice  or  announcement  issued  by the Internal   Revenue
Service  necessary  to  maintain  the qualified status  of  such  Statutory
Plans, except where non-compliance would not have a material adverse effect
on OAK BROOK. No material liability  to the PBGC has been or is expected to
be incurred with respect to any Statutory Plan. The PBGC has not instituted
proceedings to terminate any Statutory  Plan.  To the best knowledge of OAK
BROOK, there exists no condition or set of circumstances  which  presents a
material  risk of termination or partial termination of any Statutory  Plan
by the PBGC.

          3:1:17:3 ACCUMULATED FUNDING DEFICIENCY.

Except as provided  in  Section  3:1:17:3  of the Disclosure Schedule, full
payment has been made of all amounts which are  required under the terms of
each statutory plan, ERISA or other applicable laws  to  have  been paid as
contributions   to   such  Statutory  Plan,  and  no   accumulated  funding
deficiency (as defined  in  Section  302  of  ERISA  and Section 412 of the
Code), whether or not waived, exists with respect to any Statutory Plan.

          3:1:17:4 RELATIONSHIP OF BENEFITS TO PENSION PLAN ASSETS.

The current value of all accrued benefits, both vested  and unvested, under
all  Statutory Plans does not exceed the current value of  the   assets  of
such  Statutory  Plans  allocable  to  such  accrued  benefits,  except  as
disclosed  in  the  financial  statements  described in Section 3:1:17. For
purposes of the representation in this Section  3:1:17:4, the term "current
value" has  the meaning specified in Section 4062(b)(1)(A)  of  ERISA,  the
term  "accrued benefit" has the meaning specified in Section 3 of ERISA and
"current  value"  is  based upon the same actuarial assumptions used by OAK
BROOK.

          3:1:17:5 EXECUTION OF AGREEMENTS.

The execution and delivery of this Agreement and the Transaction Documents,
and  the consummation of  the  transaction  contemplated  hereby  will  not
involve any transaction which is subject to the prohibitions of Section 406
of ERISA  or  in  connection  with which a tax could be imposed pursuant to
Section 4975 of the Code.

          3:1:17:6 FIDUCIARY LIABILITY.

To the best of OAK BROOK's knowledge,  there have been no acts, failures to
act, omissions or transactions involving  a  Statutory  Plan  or the assets
thereof  which could result in imposition on OAK BROOK (whether  direct  or
indirect) of material damages or liability in actions brought under Section
502 or Sections 404 through 409 of ERISA.

          3:1:17:7 PENDING CLAIMS.

To the best  of  OAK  BROOK's  knowledge,  there are no claims,  pending or
overtly threatened, involving any of the Benefit  Plans  by  any current or
former  employee  (or  beneficiary  thereof) of OAK BROOK which allege  any
material violation of ERISA or the terms of the Benefit Plans, nor is there
any reasonable basis to anticipate any  such  claims involving such Benefit
Plans which would likely be successfully maintained against OAK BROOK.

          3:1:17:8 MULTIEMPLOYER PLANS.

Except as may be set forth in Schedule 3:1:17 of  the  Disclosure Schedule,
neither OAK BROOK nor any trade or business (whether  or not  incorporated)
which  together  with  OAK BROOK would be deemed to be a "single  employer"
within the meaning of Section  400(b)  of ERISA or Subsections 414(b), (c),
(m) or (o) of the Code sponsors, maintains,  or  contributes  to, or has at
any  time  in  the  six  year  period proceeding the date of this Agreement
sponsored, maintained or contributed  to,  any  place  (not exempt from the

"multiemployer plan" as such term is defined in Section 3(37) or 4001(a)(3)
of ERISA.

          3:1:17:9 NO REPORTABLE EVENT.

To the best of OAK BROOK's  knowledge, there has been no "reportable event"
(within  the  meaning  of  Section  4043(b)  of  ERISA  with   respect to a
Statutory Plan) or any "prohibited transaction" (as such term is defined in
Section 406 of ERISA and Section 4975(c) of the Code) with respect   to any
of  the  Employee  Plans.  All  reporting and disclosure requirements under
Title I of ERISA have been met.

     3:1:18 NO UNDISCLOSED DEFAULTS.

Except as set forth in Section 3:1:18  of  the  Disclosure Schedule, to the
best  knowledge of OAK BROOK, OAK BROOK is not  in  material  default  with
respect  to  any  obligation,  agreement  or covenant to be performed by it
under  any  contract  or  arrangement  of  any  kind,   including,  without
limitation,  those described in Section 3:1:18 of the Disclosure  Schedule,
which default would have a material adverse effect on OAK BROOK.

     3:1:19 TAXES AND RETURNS.

proposed, asserted, or formally assessed against OAK BROOK, and no requests
for  waivers of  the time to assess any such tax are pending, the OAK BROOK
Financials   reflect   an    adequate  accrual,  based  on  the  facts  and
circumstances  existing as of the  date  hereof,  for  all  material  taxes
payable by OAK BROOK (whether or not shown in any  return) through the date
thereof.  Except as set forth in Section 3:1:19 of the Disclosure Schedule,
all tax returns  and taxes for periods after December 31, 1999 have or will
be filed and paid  by  OAK  BROOK  on a timely basis, unless said taxes are
being contested in good faith by appropriate  proceedings.

     3:1:20 COMPLIANCE WITH LAW.

Except  as  set  forth  in Section 3:1:20  or  any  other  Section  of  the
Disclosure Schedule, to the  best  knowledge  of OAK BROOK, OAK BROOK is in
compliance with and is not in violation of or in  default  with respect to,
or  in  alleged  violation of or alleged default with respect to:  (a)  any

prospects, properties,  assets,  profits or condition of OAK BROOK.  To the
best knowledge of OAK BROOK, OAK BROOK  is  not  delinquent with respect to

Indemnitee  and  ending  on  the  date  on  which  the  liability  of  such
indemnifying   party   to  such  Indemnitee  is  fully  satisfied  by  such
indemnifying party) at a  floating  rate  equal  to  the  rate  of interest
publicly announced by Bank of America, N.T. & S.A. from time to time as its
