         all reinsurances, which inure to the benefit of this Contract (whether
         recovered or not), shall be first deducted from such loss to arrive at

36772-003 (Formerly PX60937)                                              Willis

         The phrase "ex-gratia payments" shall mean payments made as an
         accommodation by the Company in settlement of a claim for which no
         coverage exists under the Policy reinsured hereunder, subject to the
         prior approval of the Reinsurer.

         The phrase "claim-specific declaratory judgment expenses," as used in
         this Contract will mean all expenses incurred by the Company in
         connection with declaratory judgment actions brought to determine the
         Company's defense and/or indemnification obligations that are allocable
         to specific Policies and claims subject to this Contract.
         Claim-specific declaratory judgment expenses will be deemed to have
         been incurred by the Company on the date of the original loss (if any)
         giving rise to the declaratory judgment action.

         For purposes of this definition, the phrase "becomes liable to pay"
         shall mean the existence of a judgment, which the Company does not
         intend to appeal, or a release has been obtained by the Company, or the
         Company has accepted a proof of loss.

         Nothing in this clause shall be construed to mean that losses are not
         recoverable hereunder until the Company's Ultimate Net Loss has been
         ascertained.

         amount of Ultimate Net Loss in excess of $10,000,000 each and every
         Loss Occurrence, each Policy, subject to a limit of liability to the

D.       Within 30 days following the end of each month, the Company shall

         the month, which shall include the following:

         1.       Insured Name and Location
         2.       Master Policy Number
         3.       Policy Number

         8.       Net Ceded Premium

                                  ARTICLE VIII

NET RETAINED LINES

This Contract applies only to that portion of any insurances or reinsurances
covered by this Contract, which the Company retains net for its own account and,
in calculating the amount of any loss hereunder and also in computing the amount
in excess of which this Contract attaches, only loss or losses in respect of
that portion of any insurances or reinsurances which the Company retains net for
its own account shall be included.

The Company reserves the right to maintain reinsurance agreement(s) in respect
of its net retention under this Contract, and recoveries under said
reinsurance(s) shall be entirely disregarded in determining the Ultimate Net
Loss hereunder.

The amount of the Reinsurer's liability hereunder in respect of any loss or
losses shall not be increased by reason of the inability of the Company to
collect from any other reinsurers, whether specific or general, any amounts
which may have become due from them whether such inability arises from the
insolvency of such other reinsurers or otherwise.

                                   ARTICLE IX

CURRENCY

Whenever the word "Dollars" or the "$" sign appears in this Contract, they shall
be construed to mean United States Dollars and all transactions under this
Contract shall be in United States Dollars. Amounts paid or received by the
Company in any other currency shall be converted to United States Dollars at the
rate of exchange at the date such transaction is entered on the books of the
Company.

UNAUTHORIZED REINSURANCE

(Applies only to a Reinsurer who does not qualify for full credit with any
insurance regulatory authority having jurisdiction over the Company's reserves.)

As regards Policies or bonds issued by the Company coming within the scope of
this Contract, the Company agrees that when it shall file with the insurance
regulatory authority or set up on its books reserves for losses covered
hereunder which it shall be required by law to set up, it will forward to the
Reinsurer a statement showing the proportion of such reserves which is
applicable to the Reinsurer. The Reinsurer hereby agrees to fund such reserves
in respect of known outstanding losses that have been reported to the Reinsurer
and allocated loss adjustment expense relating thereto, losses and allocated
loss adjustment expense paid by the Company but not recovered from the
Reinsurer, plus reserves for losses incurred but not reported, as shown in the
statement prepared by the Company (hereinafter referred to as "Reinsurer's
Obligations") by funds withheld, cash advances or a Letter of Credit. The
Reinsurer shall have the option of determining the method of funding provided it
is acceptable to the insurance regulatory authorities having jurisdiction over
the Company's reserves.

When funding by a Letter of Credit, the Reinsurer agrees to apply for and secure
timely delivery to the Company of a clean, irrevocable and unconditional Letter
of Credit issued by a bank and containing provisions acceptable to the insurance
regulatory authorities having jurisdiction over the Company's reserves in an
amount equal to the Reinsurer's proportion of said reserves. Such Letter of
Credit shall be issued for a period of not less than one year and shall be
automatically extended for one year from its date of expiration or any future
expiration date unless 30 days (60 days where required by insurance regulatory
authorities) prior to any expiration date the issuing bank shall notify the
Company by certified or registered mail that the issuing bank elects not to
consider the Letter of Credit extended for any additional period.

The Reinsurer and Company agree that the Letters of Credit provided by the
Reinsurer pursuant to the provisions of this Contract may be drawn upon at any
time, notwithstanding any other provision of this Contract, and be utilized by
the Company or any successor, by operation of law, of the Company including,
without limitation, any liquidator, rehabilitator, receiver or conservator of
the Company for the following purposes, unless otherwise provided for in a
separate Trust Agreement:

(a)      to reimburse the Company for the Reinsurer's Obligations, the payment
         of which is due under the terms of this Contract and which has not been
         otherwise paid;

(b)      to make refund of any sum which is in excess of the actual amount
         required to pay the Reinsurer's Obligations under this Contract;

(c)      to fund an account with the Company for the Reinsurer's Obligations.
         Such cash deposit shall be held in an interest bearing account separate
         from the Company's other assets, and interest thereon not in excess of
         the prime rate shall accrue to the benefit of the Reinsurer;

36772-003 (Formerly PX60937)                                              Willis

<PAGE>

(d)      to pay the Reinsurer's share of any other amounts the Company claims
         are due under this Contract.

In the event the amount drawn by the Company on any Letter of Credit is in
excess of the actual amount required for (a) or (c) or, in the case of (d), the
actual amount determined to be due, the Company shall promptly return to the
Reinsurer the excess amount so drawn. All of the foregoing shall be applied
without diminution because of insolvency on the part of the Company or the
Reinsurer.

The issuing bank shall have no responsibility whatsoever in connection with the
propriety of withdrawals made by the Company or the disposition of funds
withdrawn, except to ensure that withdrawals are made only upon the order of
properly authorized representatives of the Company.

At annual intervals or more frequently as agreed, but never more frequently than
quarterly, the Company shall prepare a specific statement of the Reinsurer's
Obligations, for the sole purpose of amending the Letter of Credit, in the
following manner:

(a)      If the statement shows that the Reinsurer's Obligations exceed the
         balance of credit as of the statement date, the Reinsurer shall, within
         30 days after receipt of notice of such excess, secure delivery to the
         Company of an amendment to the Letter of Credit increasing the amount
         of credit by the amount of such difference.

(b)      If, however, the statement shows that the Reinsurer's Obligations are
         less than the balance of credit as of the statement date, the Company
         shall, within 30 days after receipt of written request from the
         Reinsurer, release such excess credit by agreeing to secure an
         amendment to the Letter of Credit reducing the amount of credit
         available by the amount of such excess credit.

                                   ARTICLE XI

TAXES

In consideration of the terms under which this Contract is issued, the Company
will not claim a deduction in respect of the premium hereon when making tax
returns, other than income or profits tax returns, to any state or territory of
the United States of America, the District of Columbia or Canada.

                                  ARTICLE XII

FEDERAL EXCISE TAX

(Applicable to those Reinsurers, excepting Underwriters at Lloyd's London and
other Reinsurers exempt from Federal Excise Tax, who are domiciled outside the
United States of America.)

36772-003 (Formerly PX60937)                                              Willis

                                     Page 7

<PAGE>

The Reinsurer has agreed to allow, for the purpose of paying the Federal Excise
Tax, the applicable percentage of the premium payable hereon (as imposed under
Section 4371 of the Internal Revenue Code) to the extent such premium is subject
to the Federal Excise Tax.

In the event of any return of premium becoming due hereunder, the Reinsurer will
deduct the applicable percentage from the return premium payable hereon, and the
Company or its agent should take steps to recover the tax from the United States
Government.

                                  ARTICLE XIII

NOTICE OF LOSS AND LOSS SETTLEMENTS

The Company will advise the Reinsurer promptly of all claims which in the
opinion of the Company may involve the Reinsurer and of all subsequent
developments on these claims which may materially affect the position of the
Reinsurer, such advices to include any claim for which the reserve is 50% or
more of the Company's retention.

The Reinsurer agrees to abide by the loss settlements of the Company provided
that retroactive extension of Policy terms or coverages made voluntarily by the
Company and not in response to court decisions (whether such court decision is
against the Company or other companies affording the same or similar coverages)
will not be covered under this Contract.

When so requested, the Company will afford the Reinsurer an opportunity to be
associated with the Company, at the expense of the Reinsurer, in the defense of
any claim or suit or proceeding involving this reinsurance, and the Company will
cooperate in every respect in the defense of such claim, suit or proceeding.

The Reinsurer will pay its share of loss settlements within 15 days upon receipt
and verification of proof of loss from the Company.

                                  ARTICLE XIV

LOSS IN EXCESS OF POLICY LIMITS

This Contract shall protect the Company, within the limits hereof, in connection
with the Ultimate Net Loss in excess of the limit of its original Policy, such
loss in excess of the limit having been incurred because of failure by it to
settle within the Policy limit or by reason of alleged or actual negligence,
criminal act or fraud, or bad faith in rejecting an offer of settlement or in
the preparation of the defense or in the trial of any action against its insured
or reinsured or in the preparation or prosecution of an appeal consequent upon
such action.

For the purpose of this Article, the word "loss" shall mean any amounts for
which the Company would have been contractually liable to pay had it not been
for the limit of the original Policy. However, this Article shall not apply
where the loss has been incurred due to fraud by a member of the Board of
Directors or a corporate officer of the Company acting individually or
collectively or in collusion with any individual or corporation or any other
organization or party involved in the presentation, defense or settlement of any
claim covered hereunder.

                                   ARTICLE XV

EXTRA CONTRACTUAL OBLIGATIONS

This Contract shall protect the Company within the limits hereof, where the
Ultimate Net Loss includes any Extra Contractual Obligations. The term "Extra
Contractual Obligations" is defined as those liabilities not covered under any
other provision of this Contract and which arise from the handling of any claim
on business covered hereunder, such liabilities arising because of, but not
limited to, the following: failure by the Company to settle within the Policy
limit, or by reason of alleged or actual negligence, criminal act or fraud, or
bad faith in rejecting an offer of settlement or in the preparation of the
defense or in the trial of any action against its insured or reinsured or in the
preparation or prosecution of an appeal consequent upon such action.

The date on which any Extra Contractual Obligation is incurred by the Company
shall be deemed, in all circumstances, to be the date of the original disaster
and/or casualty.

However, this Article shall not apply where the loss has been incurred due to
fraud by a member of the Board of Directors or a corporate officer of the
Company acting individually or collectively or in collusion with any individual
or corporation or any other organization or party involved in the presentation,
defense or settlement of any claim covered hereunder.

                                  ARTICLE XVI

SALVAGE AND SUBROGATION

All salvages, recoveries or payments recovered or received subsequent to loss
settlements hereunder shall be applied as if recovered or received prior to the
aforesaid settlement, and all necessary adjustments shall be made by the parties
hereto.

                                  ARTICLE XVII

ERRORS AND OMISSIONS

Any inadvertent delay, omission or error shall not be held to relieve either
party hereto from any liability, which would attach to it hereunder, if such
delay, omission or error had not been made, providing such delay, omission or
error is rectified upon discovery.

                                 ARTICLE XVIII

ACCESS TO RECORDS

The Company shall place at the disposal of the Reinsurer at all reasonable
times, and the Reinsurer shall have the right to inspect through its designated
representatives, all books, records and papers of the Company in connection with
any reinsurance hereunder or claims in connection herewith. Rights of access to
records shall survive the termination or expiration of this Contract.

                                  ARTICLE XIX

OFFSET

The Company and the Reinsurer, each at its option, may offset any balance or
balances, whether on account of premiums, claims and losses, loss expenses or
salvages due from one party to the other under this Contract; provided, however,
that in the event of the insolvency of a party hereto, offsets shall only be
allowed in accordance with applicable statutes and regulations.

                                   ARTICLE XX

ARBITRATION

As a condition precedent to any right of action hereunder, any irreconcilable
dispute between the parties to this Contract will be submitted for decision to a
board of arbitration composed of two arbitrators and an umpire meeting in Bala
Cynwyd, Pennsylvania.

Arbitration shall be initiated by the delivery of a written notice of demand for
arbitration by one party to the other within a reasonable time after the dispute
has arisen.

The members of the board of arbitration shall be active or former, disinterested
officials of insurance or reinsurance companies or Underwriters at Lloyd's,
London, not under the control or management of either party to this Contract.
Each party shall appoint its arbitrator, and the two arbitrators shall choose an
umpire before instituting the hearing. If the respondent fails to appoint its
arbitrator within 4 weeks after being requested to do so by the claimant, the
latter shall also appoint the second arbitrator.

If the two arbitrators are unable to agree upon the umpire within 30 days of
their appointment, the umpire shall be selected by a judge of any court of
competent jurisdiction.

The claimant shall submit its initial brief within 45 days from appointment of
the umpire. The respondent shall submit its brief within 45 days thereafter, and
the claimant may submit a reply brief within 30 days after filing of the
respondent's brief.

The board shall make its decision with regard to the custom and usage of the
insurance and reinsurance business. The board shall issue its decision in
writing based upon a hearing in which evidence may be introduced without
following strict rules of evidence but in which cross-examination and rebuttal
shall be allowed. The board shall make its decision within 60 days following the
termination of the hearings unless the parties consent to an extension. The
majority decision of the board shall be final and binding upon all parties to
the proceeding. Judgment may be entered upon the award of the board in any court
having jurisdiction.

If more than one reinsurer is involved in the same dispute, all such reinsurers
shall constitute and act as one party for purposes of this clause, and
communications shall be made by the Company to each of the reinsurers
constituting the one party provided, however, that nothing therein shall impair
the rights of such reinsurers to assert several rather than joint defenses or
claims, nor be construed as changing the liability of the reinsurers under the
terms of this Contract from several to joint.

36772-003 (Formerly PX60937)                                              Willis

Each party shall bear the expense of its own arbitrator and shall jointly and
equally bear with the other party the expense of the umpire. The remaining costs
of the arbitration proceedings shall be allocated by the board.

                                  ARTICLE XXI

SERVICE OF SUIT

(This Article only applies to reinsurers domiciled outside of the United States
and/or unauthorized in any state, territory, or district of the United States
having jurisdiction over the Company).

It is agreed that, in the event of the failure of the Reinsurer hereon to pay
any amount claimed to be due hereunder, the Reinsurer hereon, at the request of
the Company, will submit to the jurisdiction of a court of competent
jurisdiction within the United States. Nothing in this Article constitutes or
should be understood to constitute a waiver of the Reinsurer's rights to
commence an action in any court of competent jurisdiction in the United States,
to remove an action to a United States District Court or to seek a transfer of a
case to another court as permitted by the laws of the United States or of any
state in the United States.

It is further agreed that service of process in such suit may be made upon
Mendes and Mount, 750 Seventh Avenue, New York, New York 10019, and that in any
suit instituted the Reinsurer will abide by the final decision of such court or
of any appellate court in the event of an appeal.

The above-named are authorized and directed to accept service of process on
behalf of the Reinsurer in any such suit and/or upon the request of the Company
to give a written undertaking to the Company that they will enter a general
appearance upon the Reinsurer's behalf in the event such a suit shall be
instituted.

Further, pursuant to any statute of any state, territory or district of the
United States which makes provision therefor, the Reinsurer hereon hereby
designates the Superintendent, Commissioner or Director of Insurance or other
officer specified for that purpose in the statute, or his successor or
successors in office, as its true and lawful attorney upon whom may be served
any lawful process in any action, suit or proceeding instituted by or on behalf
of the Company or any beneficiary hereunder arising out of this Contract of
reinsurance and hereby designates the above-named as the person to whom the said
officer is authorized to mail such process or a true copy thereof.

                                  ARTICLE XXII

INSOLVENCY

In the event of the insolvency of the Company, this reinsurance shall be payable
directly to the Company or to its liquidator, receiver, conservator or statutory
successor on the basis of the liability of the Company without diminution
because of the insolvency of the Company or because the liquidator, receiver,
conservator or statutory successor of the Company has failed to pay all or a
portion of any claim. It is agreed, however, that the liquidator, receiver,
conservator or statutory successor of the Company shall give written notice to
the Reinsurer of the pendency

36772-003 (Formerly PX60937)                                              Willis
Eff: 03/01/03

                                    Page 11

<PAGE>

of a claim against the Company indicating the Policy or bond reinsured, which
claim would involve a possible liability on the part of the Reinsurer, within a
reasonable time after such claim is filed in the conservation or liquidation
proceeding or in the receivership and that, during the pendency of such claim,
the Reinsurer may investigate such claim and interpose, at its own expense, in
the proceeding where such claim is to be adjudicated, any defense or defenses
that it may deem available to the Company or its liquidator, receiver,
conservator or statutory successor. The expense thus incurred by the Reinsurer
shall be chargeable, subject to the approval of the court, against the Company
as part of the expense of conservation or liquidation to the extent of a pro
rata share of the benefit, which may accrue to the Company solely as a result of
the defense undertaken by the Reinsurer.

Where two or more reinsurers are involved in the same claim and a majority in
interest elect to interpose defense to such claim, the expense shall be
apportioned in accordance with the terms of this Contract as though such expense
had been incurred by the insolvent Company.

In the event of the insolvency of the Company, the reinsurance under this
Contract shall be payable directly by the Reinsurer to the Company or to its
liquidator, receiver, conservator or statutory successor, except as provided by
Section 4118(a) of the New York Insurance Law or except (a) where this Contract
specifically provides another payee of such reinsurance in the event of the
insolvency of the Company or (b) where the Reinsurer with the consent of the
direct insured or insureds has assumed such Policy obligations of the Company as
direct obligations of the Reinsurer to the payees under such Policies and in
substitution for the obligations of the Company to such payees.

Should the Company go into liquidation or should a receiver be appointed, all
amounts due either Company or Reinsurer under this or any other agreement,
whether by reason of premium, losses or otherwise under this Contract, shall be
subject to the right of offset at any time and from time to time and, upon the
exercise of the same, only the net balance shall be due.

In the event of the insolvency of any company or companies included in the
designation of "Company," this clause will apply only to the insolvent company
or companies.

                                 ARTICLE XXIII

GOVERNING LAW

This Contract shall be governed as to performance, administration and
interpretation by the laws of the State of Pennsylvania, exclusive of the rules
with respect to conflicts of law, except as to rules with respect to credit for
reinsurance, in which case the applicable rules of all states shall apply.

                                  ARTICLE XXIV

SEVERABILITY

If any provision of this Contract should be invalid under applicable laws, the
latter shall control but only to the extent of the conflict without affecting
the remaining provisions of this Contract.

instance shall any other party have any rights under this Contract except as
expressly provided otherwise in the INSOLVENCY ARTICLE.

                                  ARTICLE XXVI

AGENCY AGREEMENT

If more than one reinsured company is named as a party to this Contract, the
first named company will be deemed the agent of the other reinsured companies
for purposes of sending or receiving notices required by the terms and
conditions of this Contract and for purposes of remitting or receiving any
monies due any party.

                                 ARTICLE XXVII

MODE OF EXECUTION

This Contract may be executed either by an original written ink signature of
paper documents, by an exchange of facsimile copies showing the original written
ink signature of paper documents, or by electronic signature by either party
employing appropriate software technology as to satisfy the parties at the time
of execution that the version of the document agreed to by each party shall
always be capable of authentication and satisfy the same rules of evidence as
written signatures. The use of any one or a combination of these methods of
execution shall constitute a legally binding and valid signing of this Contract.
This Contract may be executed in one or more counterparts, each of which, when
duly executed, shall be deemed an original.

         paragraph), but salvages and all recoveries, including recoveries under
         all reinsurances, which inure to the benefit of this Contract (whether
         recovered or not), shall be first deducted from such loss to arrive at
         the amount of liability attaching hereunder.

36774-003 (Formerly PX60938)                                              Willis

         The phrase "ex-gratia payments" shall mean payments made as an
         accommodation by the Company in settlement of a claim for which no
         coverage exists under the Policy reinsured hereunder, subject to the
         prior approval of the Reinsurer.

         The phrase "claim-specific declaratory judgment expenses," as used in
         this Contract will mean all expenses incurred by the Company in
         connection with declaratory judgment actions brought to determine the
         Company's defense and/or indemnification obligations that are allocable
         to specific Policies and claims subject to this Contract.
         Claim-specific declaratory judgment expenses will be deemed to have
         been incurred by the Company on the date of the original loss (if any)
         giving rise to the declaratory judgment action.

         For purposes of this definition, the phrase "becomes liable to pay"
         shall mean the existence of a judgment, which the Company does not
         intend to appeal, or a release has been obtained by the Company, or the
         Company has accepted a proof of loss.

         ascertained.

         Policy on the same assured, the Reinsurer shall be liable for the
         amount of Ultimate Net Loss in excess of $10,000,000 each and every
         Loss Occurrence, each Policy, subject to a limit of liability to the

NET RETAINED LINES

This Contract applies only to that portion of any insurances or reinsurances
covered by this Contract, which the Company retains net for its own account and,

that portion of any insurances or reinsurances which the Company retains net for
its own account shall be included.

of its net retention under this Contract, and recoveries under said
reinsurance(s) shall be entirely disregarded in determining the Ultimate Net
Loss hereunder.

The amount of the Reinsurer's liability hereunder in respect of any loss or
losses shall not be increased by reason of the inability of the Company to
collect from any other reinsurers, whether specific or general, any amounts

UNAUTHORIZED REINSURANCE

(Applies only to a Reinsurer who does not qualify for full credit with any
insurance regulatory authority having jurisdiction over the Company's reserves.)

As regards Policies or bonds issued by the Company coming within the scope of
this Contract, the Company agrees that when it shall file with the insurance
regulatory authority or set up on its books reserves for losses covered
hereunder which it shall be required by law to set up, it will forward to the
Reinsurer a statement showing the proportion of such reserves which is
applicable to the Reinsurer. The Reinsurer hereby agrees to fund such reserves
in respect of known outstanding losses that have been reported to the Reinsurer
and allocated loss adjustment expense relating thereto, losses and allocated
loss adjustment expense paid by the Company but not recovered from the
Reinsurer, plus reserves for losses incurred but not reported, as shown in the
statement prepared by the Company (hereinafter referred to as "Reinsurer's
Obligations") by funds withheld, cash advances or a Letter of Credit. The
Reinsurer shall have the option of determining the method of funding provided it
is acceptable to the insurance regulatory authorities having jurisdiction over
the Company's reserves.

When funding by a Letter of Credit, the Reinsurer agrees to apply for and secure
timely delivery to the Company of a clean, irrevocable and unconditional Letter
of Credit issued by a bank and containing provisions acceptable to the insurance
regulatory authorities having jurisdiction over the Company's reserves in an
amount equal to the Reinsurer's proportion of said reserves. Such Letter of
Credit shall be issued for a period of not less than one year and shall be
automatically extended for one year from its date of expiration or any future
expiration date unless 30 days (60 days where required by insurance regulatory
authorities) prior to any expiration date the issuing bank shall notify the
Company by certified or registered mail that the issuing bank elects not to
consider the Letter of Credit extended for any additional period.

The Reinsurer and Company agree that the Letters of Credit provided by the
Reinsurer pursuant to the provisions of this Contract may be drawn upon at any
time, notwithstanding any other provision of this Contract, and be utilized by
the Company or any successor, by operation of law, of the Company including,
without limitation, any liquidator, rehabilitator, receiver or conservator of
the Company for the following purposes, unless otherwise provided for in a
separate Trust Agreement:

(a)      to reimburse the Company for the Reinsurer's Obligations, the payment
         of which is due under the terms of this Contract and which has not been
         otherwise paid;

(b)      to make refund of any sum which is in excess of the actual amount
         required to pay the Reinsurer's Obligations under this Contract;

(c)      to fund an account with the Company for the Reinsurer's Obligations.
         Such cash deposit shall be held in an interest bearing account separate
         from the Company's other assets, and interest thereon not in excess of
         the prime rate shall accrue to the benefit of the Reinsurer;

36774-003 (Formerly PX60938)                                              Willis

<PAGE>

(d)      to pay the Reinsurer's share of any other amounts the Company claims
         are due under this Contract.

In the event the amount drawn by the Company on any Letter of Credit is in
excess of the actual amount required for (a) or (c) or, in the case of (d), the
actual amount determined to be due, the Company shall promptly return to the
Reinsurer the excess amount so drawn. All of the foregoing shall be applied
without diminution because of insolvency on the part of the Company or the
Reinsurer.

The issuing bank shall have no responsibility whatsoever in connection with the
propriety of withdrawals made by the Company or the disposition of funds
withdrawn, except to ensure that withdrawals are made only upon the order of
properly authorized representatives of the Company.

At annual intervals or more frequently as agreed, but never more frequently than
quarterly, the Company shall prepare a specific statement of the Reinsurer's
Obligations, for the sole purpose of amending the Letter of Credit, in the
following manner:

(a)      If the statement shows that the Reinsurer's Obligations exceed the
         balance of credit as of the statement date, the Reinsurer shall, within
         30 days after receipt of notice of such excess, secure delivery to the
         Company of an amendment to the Letter of Credit increasing the amount
         of credit by the amount of such difference.

(b)      If, however, the statement shows that the Reinsurer's Obligations are
         less than the balance of credit as of the statement date, the Company
         shall, within 30 days after receipt of written request from the
         Reinsurer, release such excess credit by agreeing to secure an
         amendment to the Letter of Credit reducing the amount of credit
         available by the amount of such excess credit.

                                   ARTICLE XI

TAXES

In consideration of the terms under which this Contract is issued, the Company
will not claim a deduction in respect of the premium hereon when making tax
returns, other than income or profits tax returns, to any state or territory of
the United States of America, the District of Columbia or Canada.

                                   ARTICLE XII

FEDERAL EXCISE TAX

(Applicable to those Reinsurers, excepting Underwriters at Lloyd's London and
other Reinsurers exempt from Federal Excise Tax, who are domiciled outside the
United States of America.)

36774-003 (Formerly PX60938)                                              Willis

                                     Page 7
<PAGE>

The Reinsurer has agreed to allow, for the purpose of paying the Federal Excise
Tax, the applicable percentage of the premium payable hereon (as imposed under
Section 4371 of the Internal Revenue Code) to the extent such premium is subject
to the Federal Excise Tax.

In the event of any return of premium becoming due hereunder, the Reinsurer will
deduct the applicable percentage from the return premium payable hereon, and the
Company or its agent should take steps to recover the tax from the United States
Government.

                                  ARTICLE XIII

NOTICE OF LOSS AND LOSS SETTLEMENTS

The Company will advise the Reinsurer promptly of all claims which in the
opinion of the Company may involve the Reinsurer and of all subsequent
developments on these claims which may materially affect the position of the
Reinsurer, such advices to include any claim for which the reserve is 50% or
more of the Company's retention.

The Reinsurer agrees to abide by the loss settlements of the Company provided
that retroactive extension of Policy terms or coverages made voluntarily by the
Company and not in response to court decisions (whether such court decision is
against the Company or other companies affording the same or similar coverages)
will not be covered under this Contract.

When so requested, the Company will afford the Reinsurer an opportunity to be
associated with the Company, at the expense of the Reinsurer, in the defense of
any claim or suit or proceeding involving this reinsurance, and the Company will
cooperate in every respect in the defense of such claim, suit or proceeding.

The Reinsurer will pay its share of loss settlements within 15 days upon receipt
and verification of proof of loss from the Company.

                                   ARTICLE XIV

LOSS IN EXCESS OF POLICY LIMITS

This Contract shall protect the Company, within the limits hereof, in connection
with the Ultimate Net Loss in excess of the limit of its original Policy, such
loss in excess of the limit having been incurred because of failure by it to
settle within the Policy limit or by reason of alleged or actual negligence,
criminal act or fraud, or bad faith in rejecting an offer of settlement or in
the preparation of the defense or in the trial of any action against its insured
or reinsured or in the preparation or prosecution of an appeal consequent upon
such action.

For the purpose of this Article, the word "loss" shall mean any amounts for
which the Company would have been contractually liable to pay had it not been
for the limit of the original Policy. However, this Article shall not apply
where the loss has been incurred due to fraud by a member of the Board of
Directors or a corporate officer of the Company acting individually or
collectively or in collusion with any individual or corporation or any other
organization or party involved in the presentation, defense or settlement of any
claim covered hereunder.

                                   ARTICLE XV

EXTRA CONTRACTUAL OBLIGATIONS

This Contract shall protect the Company within the limits hereof, where the
Ultimate Net Loss includes any Extra Contractual Obligations. The term "Extra
Contractual Obligations" is defined as those liabilities not covered under any
other provision of this Contract and which arise from the handling of any claim
on business covered hereunder, such liabilities arising because of, but not
limited to, the following: failure by the Company to settle within the Policy
limit, or by reason of alleged or actual negligence, criminal act or fraud, or
bad faith in rejecting an offer of settlement or in the preparation of the
defense or in the trial of any action against its insured or reinsured or in the
preparation or prosecution of an appeal consequent upon such action.

The date on which any Extra Contractual Obligation is incurred by the Company
shall be deemed, in all circumstances, to be the date of the original disaster
and/or casualty.

However, this Article shall not apply where the loss has been incurred due to
fraud by a member of the Board of Directors or a corporate officer of the
Company acting individually or collectively or in collusion with any individual
or corporation or any other organization or party involved in the presentation,
defense or settlement of any claim covered hereunder.

                                   ARTICLE XVI

SALVAGE AND SUBROGATION

All salvages, recoveries or payments recovered or received subsequent to loss
settlements hereunder shall be applied as if recovered or received prior to the
aforesaid settlement, and all necessary adjustments shall be made by the parties
hereto.

                                  ARTICLE XVII

ERRORS AND OMISSIONS

Any inadvertent delay, omission or error shall not be held to relieve either
party hereto from any liability, which would attach to it hereunder, if such
delay, omission or error had not been made, providing such delay, omission or
error is rectified upon discovery.

                                  ARTICLE XVIII

ACCESS TO RECORDS

The Company shall place at the disposal of the Reinsurer at all reasonable
times, and the Reinsurer shall have the right to inspect through its designated

records shall survive the termination or expiration of this Contract.

OFFSET

The Company and the Reinsurer, each at its option, may offset any balance or
balances, whether on account of premiums, claims and losses, loss expenses or
salvages due from one party to the other under this Contract; provided, however,
that in the event of the insolvency of a party hereto, offsets shall only be
allowed in accordance with applicable statutes and regulations.

                                   ARTICLE XX

ARBITRATION

As a condition precedent to any right of action hereunder, any irreconcilable
dispute between the parties to this Contract will be submitted for decision to a
board of arbitration composed of two arbitrators and an umpire meeting in Bala
Cynwyd, Pennsylvania.

Arbitration shall be initiated by the delivery of a written notice of demand for
arbitration by one party to the other within a reasonable time after the dispute
has arisen.

The members of the board of arbitration shall be active or former, disinterested
officials of insurance or reinsurance companies or Underwriters at Lloyd's,
London, not under the control or management of either party to this Contract.
Each party shall appoint its arbitrator, and the two arbitrators shall choose an
umpire before instituting the hearing. If the respondent fails to appoint its
arbitrator within 4 weeks after being requested to do so by the claimant, the
latter shall also appoint the second arbitrator.

If the two arbitrators are unable to agree upon the umpire within 30 days of
their appointment, the umpire shall be selected by a judge of any court of
competent jurisdiction.

The claimant shall submit its initial brief within 45 days from appointment of
the umpire. The respondent shall submit its brief within 45 days thereafter, and
the claimant may submit a reply brief within 30 days after filing of the
respondent's brief.

The board shall make its decision with regard to the custom and usage of the
insurance and reinsurance business. The board shall issue its decision in
writing based upon a hearing in which evidence may be introduced without
following strict rules of evidence but in which cross-examination and rebuttal
shall be allowed. The board shall make its decision within 60 days following the
termination of the hearings unless the parties consent to an extension. The
majority decision of the board shall be final and binding upon all parties to
the proceeding. Judgment may be entered upon the award of the board in any court
having jurisdiction.

If more than one reinsurer is involved in the same dispute, all such reinsurers
shall constitute and act as one party for purposes of this clause, and
communications shall be made by the Company to each of the reinsurers
constituting the one party provided, however, that nothing therein shall impair
the rights of such reinsurers to assert several rather than joint defenses or
claims, nor be construed as changing the liability of the reinsurers under the
terms of this Contract from several to joint.

36774-003 (Formerly PX60938)                                              Willis

Each party shall bear the expense of its own arbitrator and shall jointly and
equally bear with the other party the expense of the umpire. The remaining costs
of the arbitration proceedings shall be allocated by the board.

                                   ARTICLE XXI

SERVICE OF SUIT

(This Article only applies to reinsurers domiciled outside of the United States
and/or unauthorized in any state, territory, or district of the United States
having jurisdiction over the Company).

It is agreed that in the event of the failure of the Reinsurer hereon to pay any
amount claimed to be due hereunder, the Reinsurer hereon, at the request of the
Company, will submit to the jurisdiction of a court of competent jurisdiction
within the United States. Nothing in this Article constitutes or should be
understood to constitute a waiver of the Reinsurer's rights to commence an
action in any court of competent jurisdiction in the United States, to remove an
action to a United States District Court or to seek a transfer of a case to
another court as permitted by the laws of the United States or of any state in
the United States.

It is further agreed that service of process in such suit may be made upon
Mendes and Mount, 750 Seventh Avenue, New York, New York 10019, and that in any
suit instituted the Reinsurer will abide by the final decision of such court or
of any appellate court in the event of an appeal.

The above-named are authorized and directed to accept service of process on
behalf of the Reinsurer in any such suit and/or upon the request of the Company
to give a written undertaking to the Company that they will enter a general
appearance upon the Reinsurer's behalf in the event such a suit shall be
instituted.

Further, pursuant to any statute of any state, territory or district of the
United States which makes provision therefor, the Reinsurer hereon hereby
designates the Superintendent, Commissioner or Director of Insurance or other
officer specified for that purpose in the statute, or his successor or
successors in office, as its true and lawful attorney upon whom may be served
any lawful process in any action, suit or proceeding instituted by or on behalf
of the Company or any beneficiary hereunder arising out of this Contract of
reinsurance and hereby designates the above-named as the person to whom the said
officer is authorized to mail such process or a true copy thereof.

                                  ARTICLE XXII

INSOLVENCY

In the event of the insolvency of the Company, this reinsurance shall be payable
directly to the Company or to its liquidator, receiver, conservator or statutory
successor on the basis of the liability of the Company without diminution
because of the insolvency of the Company or because the liquidator, receiver,
conservator or statutory successor of the Company has failed to pay all or a
portion of any claim. It is agreed, however, that the liquidator, receiver,
conservator or statutory successor of the Company shall give written notice to
the Reinsurer of the pendency

36774-003 (Formerly PX60938)                                              Willis

                                    Page 11
<PAGE>

of a claim against the Company indicating the Policy or bond reinsured, which
claim would involve a possible liability on the part of the Reinsurer, within a
reasonable time after such claim is filed in the conservation or liquidation
proceeding or in the receivership and that, during the pendency of such claim,
the Reinsurer may investigate such claim and interpose, at its own expense, in
the proceeding where such claim is to be adjudicated, any defense or defenses
that it may deem available to the Company or its liquidator, receiver,
conservator or statutory successor. The expense thus incurred by the Reinsurer
shall be chargeable, subject to the approval of the court, against the Company
as part of the expense of conservation or liquidation to the extent of a pro
rata share of the benefit, which may accrue to the Company solely as a result of
the defense undertaken by the Reinsurer.

Where two or more reinsurers are involved in the same claim and a majority in
interest elect to interpose defense to such claim, the expense shall be
apportioned in accordance with the terms of this Contract as though such expense
had been incurred by the insolvent Company.

In the event of the insolvency of the Company, the reinsurance under this
Contract shall be payable directly by the Reinsurer to the Company or to its
liquidator, receiver, conservator or statutory successor, except as provided by
Section 4118(a) of the New York Insurance Law or except (a) where this Contract
specifically provides another payee of such reinsurance in the event of the
insolvency of the Company or (b) where the Reinsurer with the consent of the
direct insured or insureds has assumed such Policy obligations of the Company as
direct obligations of the Reinsurer to the payees under such Policies and in
substitution for the obligations of the Company to such payees.

Should the Company go into liquidation or should a receiver be appointed, all
amounts due either Company or Reinsurer under this or any other agreement,
whether by reason of premium, losses or otherwise under this Contract, shall be
subject to the right of offset at any time and from time to time and, upon the
exercise of the same, only the net balance shall be due.

In the event of the insolvency of any company or companies included in the
designation of "Company," this clause will apply only to the insolvent company
or companies.

                                 ARTICLE XXIII

GOVERNING LAW

This Contract shall be governed as to performance, administration and
interpretation by the laws of the State of Pennsylvania, exclusive of the rules
with respect to conflicts of law, except as to rules with respect to credit for
reinsurance, in which case the applicable rules of all states shall apply.

                                  ARTICLE XXIV

SEVERABILITY

If any provision of this Contract should be invalid under applicable laws, the
latter shall control but only to the extent of the conflict without affecting
the remaining provisions of this Contract.

                                 WAR EXCLUSION

As regards interests which at time of loss or damage are on shore, no liability
shall attach hereto in respect of any loss or damage which is occasioned by war,
invasion, hostilities, acts of foreign enemies, civil war, rebellion,
insurrection, military or usurped power, or martial law or confiscation by order
of any government or public authority.

This War Exclusion Clause shall not, however, apply to interests which at time
of loss or damage are within the territorial limits of the United States of
America (comprising the fifty States of the Union and the District of Columbia,
its territories and possessions, including the Commonwealth of Puerto Rico and
including Bridges between the United States of America and Mexico provided they
are under United States ownership), Canada, St. Pierre and Miquelon, provided
such interests are insured under original policies, endorsements or binders
containing a standard war or hostilities or warlike operations exclusion clause.

Nevertheless, this clause shall not be construed to apply to loss or damage
occasioned by riots, strikes, civil commotion, vandalism, malicious damage,
including acts committed by agents of any government, party or faction engaged
in war, hostilities or other warlike operation, provided such agents are acting
secretly and not in connection with any operations of military or naval armed
forces in the country where the interests insured are situated.
