manner in which such Tax Return shall be prepared and filed, including, without limitation, the manner in which
any item of income, gain, loss, deduction or credit shall be reported, (2) whether any extensions may be
requested, (3) the elections that will be made by any member of the Consolidated Group or Combined Group, and (4)
whether any amended tax returns should be filed, (b) to control, contest, and represent the interests of the
Consolidated Group and Combined Group in any Audit and to resolve, settle, or
agree to any adjustment or deficiency proposed, asserted or assessed as a result of any Audit, (c) to file,
prosecute, compromise or settle any claim for refund, and (d) to determine whether any refunds, to which the
Consolidated Group or Combined Group may be entitled, shall be paid by way of refund or credited against the tax
liability of the Consolidated Group and Combined Group. TD Waterhouse, for itself and its subsidiaries, hereby
irrevocably appoints WISI as its agent and attorney-in-fact to take such action (including the execution of
documents) as WISI may deem appropriate to effect the foregoing.

4.2. FURNISHING INFORMATION. Each member of the WSI Group shall (a) furnish to WISI in a timely manner such
information and documents as WISI may reasonably request for purposes of (1) preparing any original or amended
Consolidated Return or Combined Return, (2) contesting or defending any Audit, and (3) making any determination
or computation necessary or appropriate under this Agreement, (b) cooperate in any Audit of any Consolidated
Return or Combined Return, (c) retain and provide on demand books, records, documentation or other information
relating to any tax return until the later of (1) the expiration of the applicable statute of limitations
(giving effect to any extension, waiver, or mitigation thereof) and (2) in the event any claim is made under this
Agreement for which such information is relevant, until a Final Determination with respect to such claim, and (d)
take such action as WISI may deem appropriate in connection therewith. WISI shall provide the WSI Group any
assistance reasonably required in providing any information requested pursuant to this Section 4.2.

4.3. EXPENSES. TD Waterhouse shall reimburse WISI for any outside legal and accounting expenses incurred by
WISI in the course of the conduct of any Audit regarding the tax liability of the Combined Group or Consolidated
Group, and for any other expense incurred by WISI in the course of any litigation relating thereto, to the extent
such costs are reasonably attributable to the WSI Group and provided WISI has conferred with TD Waterhouse as to
the portion of the Audit relating to the WSI Group. Notwithstanding the foregoing, WISI shall have the sole
discretion to control, contest, represent, file, prosecute, challenge or settle any Audit pursuant to Section 4.1.




SECTION 5. DECONSOLIDATION

5.1. CONTINUING COVENANTS. TD Waterhouse, for itself and the TD Waterhouse Affiliates, covenants that on or
after a Deconsolidation it will not, nor will it cause or permit any member of the WSI Group to make or change
any tax election, change any accounting method, amend any tax return or take any tax position on any tax return,
take any action, omit to take any action or enter into any transaction that results in any increased tax
liability or reduction of any Tax Asset of the WISI Group in respect of any Pre-Deconsolidation Period or
Straddle Period.

5.2. REATTRIBUTION OF TAX ASSETS. In the event of a Deconsolidation, WISI may, at its option, elect to
reattribute to itself certain Tax Assets of the WSI Group pursuant to Treasury Regulations Section 1.1502-20(g)
or similar provisions of other jurisdictions. If WISI makes such an election, TD Waterhouse shall comply with
any applicable requirements, including those of Treasury Regulations Section 1.1502-20(g)(5).

5.3. CARRYBACKS. WISI agrees to pay to TD Waterhouse the actual tax benefit received by the WISI Group from
the use in any Pre-Deconsolidation Period of a carryback of any Tax Asset of the WSI Group from a
Post-Deconsolidation Period. Such benefit shall be considered equal to the lesser of (a) the amount WISI would
have paid TD Waterhouse had such Tax Asset arisen in a Pre-Deconsolidation Period and (b) the excess of (1) the
amount of Federal Income Taxes imposed on the Consolidated Group or the amount of Combined Taxes imposed on the
Combined Group, as the case may, that would have been payable by the Consolidated Group or Combined Group in the
absence of such carryback over (2) the amount of Federal Income Taxes or Combined Taxes, as the case may be,
actually paid. Payment of the amount of such benefit shall be made within 90 days of the filing of the applicable
tax return for the taxable year in which the Tax Asset is utilized. If subsequent to the payment by WISI to TD
Waterhouse of any such amount, there shall be (a) a Final Determination which results in a disallowance or a
reduction of the Tax Asset so carried back or (b) a reduction in the amount of the benefit realized by the WISI
Group as a result of any other Tax Asset that arises in a Post-Deconsolidation Period, TD Waterhouse shall repay
to WISI, within 90 days of such event any amount which would not have been payable to TD Waterhouse pursuant to
this Section 5.3 had the amount of the benefit been determined in light of these events. TD Waterhouse shall
hold WISI harmless for any penalty, addition to tax or interest payable by any member of the WISI Group as a
result of any such event. Any such amount shall be paid by TD Waterhouse to WISI within 90 days of the payment
by WISI or any member of the Consolidated Group or

10

Combined Group of any such penalty, addition to tax, or
interest. Nothing in this Section 5.3 shall require WISI to file a claim for refund of Federal Income Taxes or
Combined Taxes.

Post-Deconsolidation Period shall remain in effect and its provisions shall survive for the full period of all
applicable statutes of limitation (giving effect to any extension, waiver or mitigation thereof).

business or affairs of such party) concerning the other parties hereto furnished it by such other party or its
representatives pursuant to this Agreement (except to the extent that such information can be shown to have been
(a) previously known by the party to which it was furnished, (b) in the public domain through no fault of such
party, or (c) later lawfully acquired from other sources not under a duty of confidentiality by the party to
which it was furnished), and each party shall not release or disclose such information to any other person,
except its auditors, attorneys, financial advisors, bankers and other consultants who shall be advised of and
agree to be bound by the provisions of this Section 6.4. Each party shall be deemed to have satisfied its
obligation to hold confidential information concerning or supplied by the other party if it exercises the same
care as it takes to preserve confidentiality for its own similar information.

6.5. SUCCESSORS. This Agreement shall be binding on and inure to the benefit of any successor, by merger,
acquisition of assets or otherwise, to any of the parties hereto (including any successor of WISI and TD
Waterhouse succeeding to the tax attributes of such party under Section 381 of the Code), to the same extent as

writing, duly executed by all of the parties hereto.

6.12. SEVERABILITY. In case any one or more of the provisions in this Agreement should be invalid, illegal or

thereby.

6.13. NO THIRD PARTY BENEFICIARIES. This Agreement is solely for the benefit of the parties to this Agreement
