FIRST AMENDED AND RESTATED

DISCRETIONARY INVESTMENT MANAGEMENT AGREEMENT

This FIRST AMENDED AND RESTATED DISCRETIONARY INVESTMENT MANAGEMENT AGREEMENT (the
“Agreement”) is made the 21st day of November, 2008 and is between GOLDMAN SACHS ASSET
MANAGEMENT INTERNATIONAL, a company organized with unlimited liability under the laws of England
(the “Manager”), and [Name of ALLIED WORLD ASSURANCE COMPANY entity and place of incorporation]
(the “Customer”).

WHEREAS, the Manager is engaged in the business of providing investment advisory and
management services;

WHEREAS, the Manager is headquartered in the United Kingdom and has significant assets and
employees in the United Kingdom in connection with providing investment advisory and management
services; and

WHEREAS, the Customer wishes to use the investment management services of the Manager in
respect of the Customer’s entire investment portfolio and the Manager is willing to provide such
services subject to the terms and conditions set forth below.

THE PARTIES AGREE THAT:

1. Interpretation. References to statutory provisions, regulations, notices or the
rules of the UK Financial Services Authority (“FSA”) and the Rules of the FSA (the “Rules”) shall
include those provisions, regulations, notices or Rules as amended, extended, consolidated,
substituted or re-enacted from time to time. Unless a term is otherwise defined in or pursuant to
this Agreement, the terms shall have the same meaning herein as in the Rules. References to
“Section(s)” are to sections of this Agreement and headings are instead for convenience only and
shall not affect construction of this Agreement.

2. Appointment and Acceptance.

2.1 The Manager is hereby appointed as the investment manager of the Account (as defined in
Section 3) for the purpose of selecting and executing transactions which are in compliance with the
investment guidelines (as set out in Appendix A, the “Guidelines”) as agent of the Customer, and
the Manager hereby accepts such appointment. Notwithstanding anything in this Agreement to the
contrary, the Manager may, at its own discretion, delegate any or all of its discretionary
investment, advisory and other rights, powers, functions and obligations hereunder to any affiliate
of the Manager, without further consent of the Customer; provided that the Manager shall always
remain liable to the Customer for its obligations hereunder and for all actions of any such
affiliates to the same extent as the Manager is liable for its own actions hereunder. In such
event, references herein to the Manager shall be deemed to be references to the relevant affiliate
to which the Manager delegates responsibilities hereunder. The Manager is regulated by FSA in the
conduct of its investment business in the United Kingdom. For purposes of this Agreement, the
lower case term “affiliate(s)” shall be defined as any entity controlled, directly or indirectly by
the Manager, any entity that controls, directly or indirectly, the Manager or an entity directly or
indirectly under common control with the Manager.

2.2 The Customer may from time to time, upon at least 10 day’s written notice to the Manager,
amend the Guidelines; provided that the Customer may not amend the Guidelines; to impose additional
monitoring, reporting or other material obligations on the Manager without the Manager’s consent.
In the event of an amendment to the Guidelines, the parties shall mutually agree to an appropriate
fee schedule for any additional asset class.

2.3 The Manager may in its sole discretion, in accordance with the Guidelines, invest the
Account in any investment company, unit trust or other collective investment fund, registered or
non-registered, for which the Manager or any of its affiliates serves as investment adviser
(“Affiliated Fund(s)”); provided, however, that in respect of the fixed income account any such
Affiliated Fund shall be a money market sweep vehicle or similar fund for the management of short
term cash balances in the Account, or in the Goldman Sachs Funds S.I.C.A.V. – Global High Yield
Portfolio. In connection with such investments in an Affiliated Fund, the Customer will, except as
otherwise agreed in writing, pay all fees associated with investing in the Affiliated Fund, and any
Affiliated Fund’s advisory or administrative fee will not be offset against fees payable in
accordance with the fee schedule hereunder.  The Customer acknowledges that the fees paid in
connection with an Affiliated Fund may be higher than fees for certain comparable, non affiliated
collective investment funds.

2.4 Based on the information available to the Manager, the Manager has categorised the
Customer as a professional client within the meaning of the Markets in Financial Instruments
Directive (“MiFID”). The Customer has the right to request re-categorisation as a retail client.
However, the Manager will not act as an investment manager for the Account under this Agreement
where the Customer requests categorisation as a retail client.

3. Account.

3.1 The “Account” shall initially consist of the cash and other assets of the Customer listed
in the schedule of assets separately furnished in writing to the Manager by the Customer. Any cash,
securities or other assets delivered by the Customer to its Custodian (as defined in Section 6) or
deposited by the Customer in its account designated for such purpose by notice to the Manager, plus
all investments, reinvestments and proceeds of the sale thereof, including, without limitation, all
interest, dividends and appreciation on investments shall also comprise part of the “Account”. The
Account may be divided into one or more “Sub-Accounts” with each subject to separate fee schedules
and Guidelines. The Customer shall notify the Manager of any additions made to, or withdrawals
made from, the Account; it being understood and agreed, that the Customer shall not withdraw funds
from the Account in order to invest such funds, including without limitation in any other money
market investment vehicle.

3.2 In the event that the Customer notifies the Manager of a pending addition to the Account
on a specified future date, the Manager shall have the authority to effect transactions on behalf
of the Customer for settlement on or after the specified date on the assumption that such assets
shall become part of the Account by such date and the Customer shall be responsible for all
transactions effected on the basis of such assumption.

3.3 The Manager shall in respect of investments held in the Account assist the Customer in
respect of any obligations to disclose shareholdings under Part VI the Disclosure and Transparency
Rules Sourcebook of the Rules and Part 22 of the Companies Act 1985 (or, where agreed by the
Parties in writing, similar overseas rules or legislation).

4. Authority of Manager.

4.1 The Manager is hereby authorized to supervise and direct the investment and reinvestment
of the assets in the Account, with full authority and at its discretion, on the Customer’s behalf
and at the Customer’s risk, subject to the terms of this Agreement and the Guidelines and subject
to the Manager’s assessment of suitability in light of the investment objective.

4.2 Failure to comply with any specific guideline or restriction contained in the Guidelines
because of market fluctuation, changes in the capital structure of any Account company, rating
agency or credit rating changes, or withdrawals or other events outside of the Manager’s control
will not be deemed a breach of the Guidelines or this Agreement, provided that (i) the Manager
cures such failure to comply as soon as practicable after its discovery by the Manager, or (ii) the
Manager believes that such a cure would not be in the best interests of the Customer, the Manager
promptly notifies the Customer of such non-compliance and its belief with respect to cure, and the
Customer provides written notice instructing the Manager to allow the Account to remain outside the
Guidelines in respect of such non-compliance.

4.3 Subject to the Guidelines, the Manager’s authority shall include, without limitation, the
power to buy, sell, retain, exchange or otherwise deal in investments and effect transactions; and
to exercise all such other powers as the Manager in its sole discretion deems appropriate in
relation to investing and executing transactions for the Account.

4.4 The Manager may give the Customer investment advice in such manner as may be agreed with
the Customer or otherwise as the Manager deems fit.

4.5 Subject to any other written instructions of the Customer, the Manager is hereby appointed
the Customer’s agent and attorney-in-fact to exercise in its discretion all rights and perform all
duties which may be exercisable in relation to any assets in the Account, including, without
limitation, the right to vote, tender or exchange any securities in the Account, to execute
waivers, consents and other instruments with respect to such securities, to endorse, transfer or
deliver such securities and to participate in or consent to any class action, plan of
reorganization, merger, combination, consolidation, liquidation or similar plan with reference to
such securities. Notwithstanding the above, the Customer or its Custodian, and not the Manager,
shall make any and all filings in connection with any securities litigation or class action
lawsuits involving securities held or that were held in the Account. However, the Manager shall
not incur any liability to the Customer by reason of any exercise of, or failure to exercise, any
such discretion, and further, the Manager shall not incur any liability for any failure arising
from an act or omission of a person other than the Manager, in each case, subject to the Manager’s
standard of liability as set forth in Section 8.1 hereof. The Customer understands that the
Manager may, from time to time and at the Manager’s expense, establish guidelines for the voting of
proxies and employ the services of a proxy voting service in exercising proxy votes.

4.6 The Customer hereby authorizes the Manager to open accounts (for example with brokers and
other market counterparties) and execute documents, warranties, indemnities and representation
letters in the name of, binding against and on behalf of the Customer to the extent customary and
reasonably necessary or desirable in the Manager’s view to carry out the Manager’s activities under
this Agreement.

4.7 The Customer agrees to notify the Manager immediately in writing in the event that the
authority and/or discretion of the Manager, as contemplated by this Section 4, becomes or is
reasonably likely to become fettered in any way which may include, without limitation,
circumstances where any of the assets in the Account become subject to rights exercisable by third
parties where such third parties may have a right of veto of those investment decisions made by the
Manager (referred to in this Section 4.7 as “Controlled Assets”). The Manager shall use its
reasonable endeavours, subject always to applicable law and regulation and the terms hereof, to
comply with any direction of the Customer in respect of the Controlled Assets but, except for the
Manager’s gross negligence, bad faith or wilful misconduct to comply with such direction (which
must be reasonable), the Manager shall not be responsible for any losses or liabilities howsoever
incurred and which are attributable to the Controlled Assets.

5. Account Transactions.

5.1 The Manager will place orders for the execution of transactions for the Account on behalf
of the Customer. When executing transactions or placing orders with other entities for execution
that result from decisions by the Manager to deal when providing the service of portfolio
management for the Account on behalf of the Customer, the Manager shall take all reasonable steps
to obtain on a best execution (in such manner as that obligation may be satisfied under the Rules)
and shall act in good faith and with due diligence in its choice and use of any counterparties.

5.2 The Customer consents to the Manager’s policy to obtain best execution, information on
which is set out in “Information on GSAMI’s Execution Policy” at Appendix D (the “Execution
Policy”) and to the Manager effecting transactions on behalf of the Customer outside a regulated
market or multilateral trading facility.

5.3 The Manager shall provide the Customer in writing with information about/notify the
Customer of any amendments to the Execution Policy that are material in the context of this
Agreement, no less than 45 days before those amendments take effect.

5.4 The Customer authorizes the Manager and its affiliates to bunch and aggregate orders for
the Account in accordance with the Rules. The Manager is not required to aggregate orders. In
accordance with the Rules, the Manager hereby notifies the Customer that Aggregation may work to
the Customer’s disadvantage in relation to a particular order.

5.5 The Manager may not execute trades with or through itself or any of its affiliates acting
as agent or as principal. The Manager may execute transactions in which the Manager, its
affiliates and/or their personnel have interests as described in Section 2.3 and 14 hereof. The
Manager is authorized to effect cross transactions between the Account and other accounts managed
by the Manager and its affiliates provided that remuneration paid by the Account for the execution
of such transactions shall be paid to broker-dealers unaffiliated with the Manager and provided,
further, that the terms of such cross transactions are, in the Manager’s reasonable view, fair and
equitable to the Customer. Such cross transactions enable the Manager to purchase or sell a block
of securities for the Account at a set price and possibly avoid an unfavorable price movement that
may be created through entrance into the market with such purchase or sell order. The Manager
believes that such transactions can provide meaningful benefits for its clients. However, the
Customer should note that the Manager has a potentially conflicting division of loyalties and
responsibilities regarding both parties to such transactions.

5.6 The Manager may cause the Custodian to advance cash on the Customer’s behalf to facilitate
execution and settlement of transactions in the Account.

6. Custody. The Account shall be held by a custodian (the “Custodian”) appointed by
the Customer pursuant to a separate custody agreement or by the Customer itself. The Manager and,
except as may be otherwise specifically provided by the separate custody agreement, its affiliates
shall at no time have custody or physical control of the assets and cash in the Account. The
Customer shall instruct the Custodian to provide the Manager with such periodic reports concerning
the status of the Account as the Manager may reasonably request from time to time. The Customer
will not change the Custodian without giving the Manager reasonable prior written notice of its
intention to do so together with the name and other relevant information with respect to the new
Custodian. The quarterly fee shall be billed in arrears for each calendar quarter and payable in
U.S. dollars within 30 days upon receipt of a reasonably detailed invoice. The Customer will
arrange for the Custodian to send to the Customer, no less than quarterly, a statement showing all
amounts disbursed from the Customer’s Custodian account to the Manager. Neither the Manager nor
its affiliates shall have any responsibilities for the selection, appointment or monitoring of the
Custodian and shall not be liable for any act or omission of the Custodian.

7. Representations and Warranties.

7.1 The Manager hereby represents and warrants to and agrees with the Customer that:

7.1.1 this Agreement has been duly authorized, executed and delivered by the Manager and
constitutes its legal, valid and binding obligation;

and, when duly entered into with a counterparty, will be the legal, valid and binding Obligations
of the Customer; (ii) all transactions and agreements that the Customer has authorized under this
Agreement and the Guidelines which the Manager enters on behalf of the Customer will not violate
the constituent documents of, or any law, rule, regulation, order or judgment binding on the

no governmental or other notice or consent is required in connection with the execution, delivery
or performance of this Agreement by the Customer or of any agreements governing or relating to
Obligations, subject to the Manager’s compliance with Section 7.2.3; (iii) the Customer will give

8 Limitation of Liability; Indemnification.

8.1 Except for a breach of confidentiality obligations as provided for in Section 12, the
Manager shall not be liable for any expenses, losses, damages, liabilities, demands, charges and
claims of any kind or nature whatsoever (including, without limitation, any legal expenses and
costs and expenses relating to investigating or defending any demands, charges and claims)
(collectively “Losses”) by or with respect to the Account, except to the extent that such Losses
are the result of an act or omission taken or omitted by the Manager during the term of the
Agreement hereunder which constitutes gross negligence, bad faith or willful misconduct with
respect to the Manager’s obligations hereunder (including its obligations to select and execute
transactions in accordance with the Guidelines as described in Section 2 hereof or if the Manager
accepted instructions which do not correspond to terms of Section 9 of this Agreement), with
respect to which the Manager shall remain liable. Without limitation, the Manager shall not have
breached any obligation to the Customer and shall incur no liability for Losses resulting from (i)
the actions of the Customer or its Custodian or other agents, following directions of the Customer
or the Manager’s failure to follow unlawful or unreasonable directions of the Customer or (ii)
force majeure or other events beyond the control of the Manager, including, without limitation, any
failure, default or delay in performance resulting from computer failure, breakdown in
communications or market disruptions not reasonably within the control of the Manager. No warranty
is given by the Manager as to the performance or profitability of the Account or any part thereof
or that the investment objectives of the Account, including, without limitation, its risk control
or return objectives, will be successfully accomplished, and the Manager shall have no liability in
respect of any Losses arising as a result of a change in market conditions, unless resulting from
the Manager’s gross negligence, bad faith or willful misconduct (with respect to which the Manager
shall remain liable). Where the investment objective of the Account refers to a benchmark index,
for the avoidance of doubt the Manager will not be obliged to manage the Account in accordance with
the composition of that index, but will be subject at all times to the Investment Guidelines.

8.2 The Customer shall reimburse, indemnify and hold harmless the Manager, its affiliates and
their directors, officers and employees and any person controlled by or controlling the Manager
(collectively, the “indemnitees”) for, from and against any and all Losses (i) relating to this
Agreement or the Account arising out of any misrepresentation or act or omission or alleged act or
omission on the part of the Customer, the Custodian or any of their agents or (ii) arising or
relating to any demand, charge or claim in respect of an indemnities’ acts, omissions,
transactions, duties, obligations or responsibilities arising pursuant to this Agreement, unless
such demand, charge or claim results from the Manager’s gross negligence, bad faith or willful
misconduct or such indemnitees shall have settled such demands, charges and claims without the
Customer’s consent.

8.3 Nothing in this Agreement shall exclude or restrict any duty or liability to the Customer
which the Manager may have under MiFID or the Financial Services and Markets Act 2000, as amended,
or any rules regulations made under it, including the Rules. Additionally, U.S. federal and state
securities laws impose liabilities under certain circumstances on persons who act in good faith,
and nothing in this Agreement shall constitute a waiver or limitation of any rights that the
Customer may have under any applicable U.S. federal or state securities laws.

9. Directions to the Manager.

9.1 All directions to the Manager shall be in writing signed either by the Customer or by an
authorized agent of the Customer.

9.2 For this purpose, the term “in writing” shall include directions given by facsimile or
electronic mail. A list of persons authorized to give instructions to the Manager hereunder with
specimen signatures is set out in Appendix C to this Agreement that may be amended from time to
time. The Customer may revise the list of authorized persons from time to time by sending the
Manager a revised list which has been certified either by the Customer or by a duly authorized
agent of the Customer. The Manager shall be entitled to rely upon any direction from, or document
signed by, any person listed in Appendix C of this Agreement. The Manager shall have no liability
in respect of fax transmission errors or interceptions of email communications by unauthorized
persons; provided, however, that any such interceptions do not occur due to grossly negligent
security measures of the Manager. The Manager shall be under no duty to make any investigation or
inquiry as to any statement contained in any writing and may accept the same as conclusive evidence
of the truth and accuracy of the statements therein contained.

9.3 Directions given by the Customer to the Manager shall be effective only upon actual
receipt by the Manager and shall be acknowledged by the Manager through its actions, unless the
Customer is advised by the Manager otherwise or unless the Customer requests otherwise in the text
of its directions.

10. Reports and Valuation. The Manager shall promptly provide the Customer with
written reports containing the valuations and status of the Account on a quarterly basis, or
otherwise as the Customer may from time to time reasonably request, except that written
confirmations of brokerage transactions shall be promptly sent solely to the Manager.

11. Non-Assignability. No assignment of this Agreement may be made by Manager except
with the written consent of the Customer, provided that an assignment by operation of law shall not
require the written consent of the Customer unless required by applicable law. No assignment of
this Agreement may be made by the Customer except with the written consent of the Manager. Subject
to the foregoing, the provisions of this Agreement shall be binding upon and shall inure to the
benefit of and be enforceable by each of the parties hereto and their respective successors and
permitted assigns. The Customer will be notified of a change in control of the Manager within a
reasonable time thereafter.

12. Confidential Information. All proprietary client information of the Customer and
proprietary information and advice of the Manager (collectively the “Information”) shall be treated
as confidential by the other party hereto and shall not be disclosed to the public by such other
party except (i) if such Information is or becomes available to the public or industry sources
other than as a result of disclosure by the receiving party or by someone known to such party to
have an obligation to keep such Information confidential; (ii) receiving party can demonstrate that
the Information was in its possession prior to the time of disclosure by the disclosing party;
(iii) the information is independently developed by or for the receiving party by persons not
having access to the Information hereunder; or (iv) the Information is, on the advice of legal
counsel, required to be disclosed by law or by legal process. Notwithstanding the foregoing, if the
receiving party receives a request to disclose all or any part of the Information under a subpoena
or other order issued by a court of competent jurisdiction or by a government agency, the
receiving party shall, if possible: (i) give the disclosing party prompt written notice of such
request; (ii) consult with the disclosing party on the advisability of taking reasonable steps to
resist or narrow that request and if disclosure of that Information is required, furnish only such
portion of the Information as the receiving party is advised by counsel is legally required to be
disclosed; and (iii) cooperate with the disclosing party, at the disclosing party’s expense in
obtaining protective orders or undertakings that confidential treatment will be afforded any of
such Information so furnished. Notwithstanding the foregoing, the Customer hereby consents to the
disclosure by the Manager of the Customer’s name to brokers and dealers (including, without
limitation, any futures brokers and futures commission merchants if futures are permitted by the
Guidelines) whether executing or clearing, to carry out the Manager’s activities on behalf of the
Customer under this Agreement. Notwithstanding the foregoing, with the prior written consent of
the Customer, the Manager may disclose the Customer’s name to consultants and prospective clients
as part of a representative client list in connection with the compilation of marketing materials.

The receiving party acknowledges and agrees that, in the event of any breach of this Agreement, the
disclosing party might be irreparably and immediately harmed and unable to be made whole by
monetary damages. It is accordingly agreed that the disclosing party, in addition to any other
remedy to which it may be entitled in law or equity, will be entitled to seek an injunction or
injunctions to remedy breaches of this Agreement.

13. Remuneration. For its discretionary investment management services hereunder, the
Manager shall be entitled to the fees and terms of payment as set forth in Appendix B to this
Agreement, as the same may be amended from time to time by written agreement signed by the Manager
and the Customer. The Manager may, at its discretion, make payments out of such fees to any
affiliate from which the Manager obtains assistance. Custodial fees, if any, are charged separately
by the Custodian for the Account and are not included in Appendix B unless specifically set forth
therein. The Customer shall be responsible for payment of brokerage commissions, transfer fees,
registration costs, taxes and other similar reasonable out of pocket costs and transaction-related
expenses and fees arising out of transactions in/management of the Account and the Customer hereby
authorizes the Manager to incur such expenses for the Account, provided that any such expenses so
incurred are disclosed in reasonable detail in reports contemplated by Section 10 hereof. Without
prejudice and in addition to any lien, right of set-off or other similar rights to which the
Manager or its affiliates may be entitled to exercise whether by law or otherwise over the Account
(or any securities or moneys therein), the Account (and moneys and securities therein) shall be
subject to a general lien and charge in favour of the Manager in so far as there remains any
outstanding amounts due from the Customer to the Manager under this Agreement. All fees are
exclusive of any value added or similar taxes which, if payable, shall be payable by the Customer.

14. Services to Other Clients; Certain Affiliated Activities.

14.1 The relationship between the Manager and the Customer is as described in this Agreement
and permits, expressly as set forth herein, the Manager and its affiliates to effect transactions
with or for the Account in instances in which the Manager and its affiliates may have multiple
interests. However, if the Manager acts in circumstances where it has a material interest or
conflict of interests, the Manager will take reasonable steps to ensure the Customer is treated
fairly. In this regard, the Manager has established, implemented and maintains a written conflicts
of interest policy (full details of which are available on request from the Manager). In this
regard the Customer understands that the Manager is part of a worldwide, full service investment
banking, broker-dealer, asset management organization, and as such, the Manager and its affiliates
(the “Firm”) and their managing directors, directors, officers and employees (“Personnel”) may have
multiple advisory, transactional and financial and other interests in securities, instruments and
companies that may be purchased, sold or held by the Manager for the Account. The Firm may act as
adviser to clients in investment banking, financial advisory, asset management and other capacities
related to instruments that may be purchased, sold or held in the Account, and the Firm may issue,
or be engaged as underwriter for the issuer of, instruments that the Account may purchase, sell or
hold. At times, these activities may cause departments of the Firm to give advice to clients that
may cause these clients to take actions adverse to the interests of the Customer. The Firm and
Personnel may act in a proprietary capacity with long or short positions, in instruments of all
types, including those that the Account may purchase, sell or hold. Such activities could affect
the prices and the availability of the securities and instruments that the Manager seeks to buy or
sell for the Account, which could adversely impact the performance of the Account. Personnel may
serve as directors of companies the securities of which the Account may purchase, sell or hold. The
Firm and Personnel may give advice, and take action, with respect to any of the Firm’s clients or
proprietary accounts that may differ from the advice given, or may involve a different timing or
nature of action taken, than with respect to any one or all of the Manager’s accounts, and effect
transactions for such clients or proprietary accounts at prices or rates that may be more or less
favorable than for the Account. Without limitation to the foregoing the Customer understands that
since the Firm is a worldwide, full service investment banking, broker-dealer, asset management
organization, and as such the Firm and (where applicable) Firm Personnel may subject to compliance
with the Rules, obtain from and keep or pay to third parties (including affiliates) any profits,
commissions and fees in connection with their activities for other clients and their own accounts.
In such circumstances, the Manager shall not be required to take account of such profits,
commissions and fees in determining its own fees or sums due on the Customer’s account; and/or
receive from and keep or pay to third parties (including affiliates) fees, commissions or other
benefits and share charges in respect of the services provided to the Customer hereunder with third
parties (including affiliates). The amount or basis of any fee, commission or other benefit
received by the Manager from such a third party or paid by the Manager to such a third party in
connection with the services provided to the Customer hereunder, and the amount or basis of any
charges shares with a third party (other than employees of the Manager) will be disclosed to the
Customer to the extent required by the Rules, and such disclosure may be in summary form only.
Further details on the Manager’s conflict of interest policy will be available upon request. The
Firm and Personnel may obtain and keep any profits, commissions and fees accruing to them in
connection with other activities for themselves and other clients and their own accounts and the
Manager’s fees as set forth in this Agreement shall not be abated thereby.

14.2 The Customer understands that the ability of the Manager and its affiliates to effect
and/or recommend transactions may be restricted by applicable regulatory requirements in the United
Kingdom (including the Rules), the European Union, the United States or elsewhere and/or their
internal policies designed to comply with such requirements. As a result, there may be periods
when the Manager will not initiate or recommend certain types of transactions in certain
investments when the Manager or its affiliates are performing investment banking or other services
or when aggregated position limits have been reached and the Customer will not be advised of that
fact. Without limitation, when the Manager or an affiliate is engaged in an underwriting or other
distribution of securities of a company, the Manager may in certain circumstances be prohibited
from purchasing or recommending the purchase of certain securities of that company for its clients.

14.3 The Customer should be aware that from time to time at the Manager’s discretion, advisory
Personnel may consult with Personnel in proprietary trading or other areas of the Firm or form
investment policy committees comprised of such Firm Personnel, and the performance of Firm
Personnel obligations related to their consultation with the Manager could conflict with their
areas of primary responsibility within the Firm. In connection with their activities with the
Manager, such Firm Personnel may receive information regarding the Manager’s proposed investment
activities which is not generally available to the public. However, there will be no obligation on
the part of such Firm Personnel to make available for use by investment management clients of the
Manager any information or strategies known to them or developed in connection with their client,
proprietary or other activities. In addition, the Firm will be under no obligation to make
available any research or analysis prior to its public dissemination. Furthermore, the Firm shall
have no obligation to recommend for purchase or sale by investment management accounts of the
Manager any security that the Firm or Personnel may purchase for themselves or for any other
clients. The Firm shall have no obligation to seek to obtain any material, non-public (“inside”)
information about any issuer of securities, and will not effect transactions for investment
management accounts of the Manager on the basis of any inside information as may come into its
possession.

14.4 In the event that the Manager is authorized to effect transactions in Derivatives
pursuant to the Guidelines, including contingent liability investments, it may settle or close out
such transactions without further reference to the Customer. The Manager may debit the Account
with any sums required to pay or supplement any deposit or margin support of such transaction.

15. Risk Disclosures. The Customer’s attention is drawn to Appendix E which contains
certain important risk disclosures. By executing this Agreement the Customer represents and
warrants that it has read and understood Appendix E.

16. Duration and Termination.

16.1 This Agreement may be terminated: (a) by either party upon 30 days’ prior written notice
at any time to the other party; (b) or immediately by either party in the event of a material
breach by the other party of the terms of this Agreement and failure to cure such violation within
30 days of becoming aware of, or receiving notice from, the other party of such violation; or (c)
by the Customer at any time with Cause (as defined below) or upon a Change in Control (as defined
below) of The Goldman Sachs Group, Inc. or the Manager. “Cause” shall mean (a) a willful violation
by the Manager of this Agreement or the Guidelines and (b) suspension of payments by the Manager of
its debts, entry by the Manager into an arrangement with its creditors, cessation of business by

FIRST AMENDED AND RESTATED

DISCRETIONARY INVESTMENT MANAGEMENT AGREEMENT

This FIRST AMENDED AND RESTATED DISCRETIONARY INVESTMENT MANAGEMENT AGREEMENT (the
“Agreement”) is made the 21st day of November, 2008, and is between GOLDMAN SACHS ASSET
MANAGEMENT L.P., a limited partnership organized under the laws of the State of Delaware (the
“Manager”), and [Name of ALLIED WORLD ASSURANCE COMPANY entity and place of incorporation] (the
“Customer”).

WHEREAS, the Manager is engaged in the business of providing investment advisory and
management services;

WHEREAS, the Manager is headquartered in New York, New York and has significant assets and
employees in the United States in connection with providing investment advisory and management
services; and

WHEREAS, the Customer wishes to use the investment management services of the Manager in
respect of the Customer’s entire investment portfolio and the Manager is willing to provide such
services subject to the terms and conditions set forth below.

THE PARTIES AGREE THAT:

1. Appointment and Acceptance.

1.1 The Manager is hereby appointed as the investment manager of the Account (as defined in
Section 2) for the purpose of selecting and executing transactions which are in compliance with the
investment guidelines (as set out in Appendix A, the “Guidelines”) as agent of the Customer, and
the Manager hereby accepts such appointment. Notwithstanding anything in this Agreement to the
contrary, the Manager may, at its own discretion, delegate any or all of its discretionary
investment, advisory and other rights, powers, functions and obligations hereunder to any affiliate
of the Manager, without further consent of the Customer; provided that the Manager shall always
remain liable to the Customer for its obligations hereunder and for all actions of any such
affiliates to the same extent as the Manager is liable for its own actions hereunder. In such
event, references herein to the Manager shall be deemed to be references to the relevant affiliate
to which the Manager delegates responsibilities hereunder. The Manager is regulated by the
Securities and Exchange Commission in the conduct of its investment business in the United States.
For purposes of this Agreement, the lower case term “affiliate(s)” shall be defined in Rule 12b-2
of the Securities Exchange Act of 1934, as amended.

1.2 The Customer may from time to time, upon at least 10 day’s written notice to the Manager,
amend the Guidelines; provided that the Customer may not amend the Guidelines to impose additional
monitoring, reporting or other material obligations on the Manager without the Manager’s consent.
In the event of an amendment to the Guidelines, the parties shall mutually agree to an appropriate
fee schedule for any additional asset class.

1.3 The Manager may in its sole discretion, in accordance with the Guidelines, invest the
Account in any investment company, unit trust or other collective investment fund, registered or
non-registered, for which the Manager or any of its affiliates serves as investment adviser
(“Affiliated Fund(s)”); provided, however, that any such Affiliated Fund shall be a money market
sweep vehicle or similar fund for the management of short term cash balances in the Account, or in
the Goldman Sachs Funds S.I.C.A.V. – Global High Yield Portfolio. In connection with such
investments in an Affiliated Fund, the Customer will, except as otherwise agreed in writing, pay
all fees associated with investing in the Affiliated Fund, and any Affiliated Fund’s advisory or
administrative fee will not be offset against fees payable in accordance with the fee schedule
hereunder.  The Customer acknowledges that the fees paid in connection with an Affiliated Fund may
be higher than fees for certain comparable, non affiliated collective investment funds.

 2. Account

2.1 The “Account” shall initially consist of the cash and other assets of the Customer listed
in the schedule of assets separately furnished in writing to the Manager by the Customer. Any
cash, securities or other assets delivered by the Customer to its Custodian (as defined in Section
5) or deposited by the Customer in its account designated for such purpose by notice to the
Manager, plus all investments, reinvestments and proceeds of the sale thereof, including, without
limitation, all interest, dividends and appreciation on investments shall also comprise part of the
“Account”. Subject to the written approval of the Customer, the Account may be divided into one or
more “Sub-Accounts” with each subject to separate fee schedules and Guidelines. The Customer shall
notify the Manager of any additions made to , or withdrawals made from, the Account; it being
understood and agreed, that the Customer shall not withdraw funds from the Account in order to
invest such funds, including without limitation in any other money market investment vehicle.

2.2 In the event that the Customer notifies the Manager of a pending addition to the Account
on a specified future date, the Manager shall have the authority to effect transactions on behalf
of the Customer for settlement on or after the specified date on the assumption that such assets
shall become part of the Account by such date and the Customer shall be responsible for all
transactions effected on the basis of such assumption.

3. Authority of Manager.

3.1 The Manager is hereby authorized to supervise and direct the investment and reinvestment
of the assets in the Account, with full authority and at its discretion, on the Customer’s behalf
and at the Customer’s risk, subject to the terms of this Agreement and the Guidelines.

3.2 Failure to comply with any specific guideline or restriction contained in the Guidelines
because of market fluctuation, changes in the capital structure of any Account company, rating
agency or credit rating changes, or withdrawals or other events outside of the Manager’s control
will not be deemed a breach of the Guidelines or this Agreement, provided that (i) the Manager
cures such failure to comply with the Guidelines as soon as practicable after its discovery by the
Manager, or (ii) the Manager believes that such a cure would not be in the best interests of the
Customer, the Manager promptly notifies the Customer of such non-compliance and its belief with
respect to cure, and the Customer provides written notice instructing the Manager to allow the
Account to remain outside the Guidelines in respect of such non-compliance.

3.3 Subject to the Guidelines, the Manager’s authority shall include, without limitation, the
power to buy, sell, retain, exchange or otherwise deal in investments and effect transactions; and
to exercise all such other powers as the Manager in its sole discretion deems appropriate in
relation to investing and executing transactions for the Account.

3.4 Subject to any other written instructions of the Customer, the Manager is hereby appointed
the Customer’s agent and attorney-in-fact to exercise in its discretion all rights and perform all
duties which may be exercisable in relation to any assets in the Account, including, without
limitation, the right to vote, tender or exchange any securities in the Account, to execute
waivers, consents and other instruments with respect to such securities, to endorse, transfer or
deliver such securities and to participate in or consent to any plan of reorganization, merger,
combination, consolidation, liquidation or similar plan with reference to such securities.
Notwithstanding the above, the Customer or its Custodian, and not the Manager, shall make any and
all filings in connection with any securities litigation or class action lawsuits involving
securities held or that were held in the Account. However, the Manager shall not incur
any liability to the Customer by reason of any exercise of, or failure to exercise, any such
discretion, and further, the Manager shall not incur any liability for any failure arising from an
act or omission of a person other than the Manager, in each case, subject to the Manager’s standard
of liability as set forth in Section 7.1 hereof. The Customer understands that the Manager may,
from time to time and at the Manager’s expense, establish guidelines for the voting of proxies
and employ the services of a proxy voting service in exercising proxy votes.

3.5 The Customer hereby authorizes the Manager to open accounts (for example with brokers and
other market counterparties) and execute documents, warranties, indemnities and representation
letters in the name of, binding against and on behalf of the Customer to the extent customary and
reasonably necessary or desirable in the Manager’s view to carry out the Manager’s
activities under this Agreement.

3.6 The Customer agrees to notify the Manager immediately in writing in the event that the
authority and/or discretion of the Manager, as contemplated by this Section 4, becomes or is
reasonably likely to become fettered in any way which may include, without limitation,
circumstances where any of the assets in the Account become subject to rights exercisable by third
parties where such third parties may have a right of veto of those investment decisions made by the
Manager (referred to in this Section 3.6 as “Controlled Assets”). The Manager shall use its
reasonable endeavours, subject always to applicable law and regulation and the terms hereof, to
comply with any direction of the Customer in respect of the Controlled Assets but, except for the
Manager’s gross negligence, bad faith or wilful misconduct to comply with such direction (which
must be reasonable), the Manager shall not be responsible for any losses or liabilities howsoever
incurred and which are attributable to the Controlled Assets.

4. Account Transactions.

4.1 The Manager will place orders for the execution of transactions for the Account on behalf
of the Customer on a best execution basis and in accordance with Part II of the Manager’s Form ADV,
as may be amended from time to time. The Customer authorizes the Manager and its affiliates to
bunch and aggregate orders for the Account. The Manager is not required to aggregate orders. The
Manager hereby notifies the Customer that aggregation affiliates may work against as well as for
the Customer’s interest.

4.2 The Manager may not execute trades with or through itself or any of its affiliates acting
as agent or as principal. The Manager may execute transactions in which the Manager, its
affiliates and/or their personnel have interests as described in Sections 1.3 and 13 hereof. The
Manager is authorized to effect cross transactions between the Account and other accounts managed
by the Manager and its affiliates provided that remuneration paid by the Account for the execution
of such transactions shall be paid to broker-dealers unaffiliated with the Manager and provided,
further, that the terms of such cross transactions are, in the Manager’s reasonable view, fair and
equitable to for the Customer. Such cross transactions enable the Manager to purchase or sell a
block of securities for the Account at a set price and possibly avoid an unfavorable price movement
that may be created through entrance into the market with such purchase or sell order. The Manager
believes that such transactions can provide meaningful benefits for its clients. However, the
Customer should note that the Manager has a potentially conflicting division of loyalties and
responsibilities regarding both parties to such transactions.

4.3 The Manager may cause the Custodian to advance cash on the Customer’s behalf to facilitate
execution and settlement of transactions in the Account.

5. Custody. The Account shall be held by a custodian (the “Custodian”) appointed by
the Customer pursuant to a separate custody agreement or by the Customer itself. The Manager and,
except as may be otherwise specifically provided by the separate custody agreement, its affiliates
shall at no time have custody or physical control of the assets and cash in the Account. The
Customer shall instruct the Custodian to provide the Manager with such periodic reports concerning
the status of the Account as the Manager may reasonably request from time to time. The Customer
will not change the Custodian without giving the Manager reasonable prior written notice of its
intention to do so together with the name and other relevant information with respect to the new
Custodian. The quarterly fee shall be billed in arrears for each calendar quarter and payable in
U.S. dollars within 30 days upon receipt of a reasonably detailed invoice. The Customer will
arrange for the Custodian to send to the Customer, no less than quarterly, a statement showing all
amounts disbursed from the Customer’s Custodian account to the Manager. Neither the Manager nor
its affiliates shall have any responsibilities for the selection, appointment or monitoring of the
Custodian and shall not be liable for any act or omission of the Custodian.

and, when duly entered into with a counterparty, will be the legal, valid and binding Obligations

7. Limitation of Liability; Indemnification.

7.1 Except for a breach of confidentiality obligations provided for in Section 11, the Manager
shall not be liable for any expenses, losses, damages, liabilities, demands, charges and claims of
any kind or nature whatsoever (including, without limitation, any legal expenses and costs and
expenses relating to investigating or defending any demands, charges and claims) (collectively,
“Losses”) by or with respect to the Account, except to the extent that such Losses are the result
of an act or omission taken or omitted by the Manager during the term of the Agreement hereunder
which constitutes gross negligence, bad faith or willful misconduct with respect to the Manager’s
obligations hereunder (including its obligations to select and execute transactions in accordance
with the Guidelines as described in Section 1 hereof or if the Manager accepted instructions which
do not correspond to terms of Section 8 of this Agreement), with respect to which the Manager shall
remain liable. Without limitation, the Manager shall not have breached any obligation to the
Customer and shall incur no liability for Losses resulting from (i) the actions of the Customer or
its Custodian or other agents, following directions of the Customer or the Manager’s failure to
follow unlawful or unreasonable directions of the Customer or (ii) force majeure or other events
beyond the control of the Manager, including, without limitation, any failure, default or delay in
performance resulting from computer failure, breakdown in communications or market disruptions not
reasonably within the control of the Manager. No warranty is given by the Manager as to the
performance or profitability of the Account or any part thereof or that the investment objectives
of the Account, including, without limitation, its risk control or return objectives, will be
successfully accomplished, and the Manager shall have no liability in respect of any Losses arising
as a result of a change in market conditions, unless resulting from the Manager’s gross negligence,
bad faith or willful misconduct (with respect to which the Manager shall remain liable). Where the
investment objective of the Account refers to a benchmark index as set out in the Guidelines, for
the avoidance of doubt the Manager will not be obliged to manage the Account in accordance with the
composition of that index, but will be subject at all times to the Investment Guidelines.

7.2 The Customer shall reimburse, indemnify and hold harmless the Manager, its affiliates and
their directors, officers and employees and any person controlled by or controlling the Manager
(collectively, the indemnitees”) for, from and against any and all Losses (i) relating to this
Agreement or the Account arising out of any misrepresentation or act or omission or alleged act or
omission on the part of the Customer, the Custodian or any of their agents or (ii) arising or
relating to any demand, charge or claim in respect of an indemnitees’ acts, omissions,
transactions, duties, obligations or responsibilities arising pursuant to this Agreement, unless
such demand, charge or claim results from the Manager’s gross negligence, bad faith or willful
misconduct or such indemnitees shall have settled such demands, charges and claims without the
Customer’s consent.

7.3 Nothing in this Agreement shall exclude or restrict any duty or liability to the Customer
which the Manager may have under applicable laws, rules or regulations. Additionally, U.S. federal
and state securities laws impose liabilities under certain circumstances on persons who act in good
faith, and nothing in this Agreement shall constitute a waiver or limitation of any rights that the
Customer may have under any applicable U.S. federal or state securities laws.

8. Directions to the Manager

8.1 All directions to the Manager shall be in writing signed either by the Customer or by an
authorized agent of the Customer.

8.2 For this purpose, the term “in writing” shall include directions given by facsimile or
electronic mail. A list of persons authorized to give instructions to the Manager hereunder with
specimen signatures is set out in Appendix C to this Agreement that may be amended from time to
time. The Customer may revise the list of authorized persons from time to time by sending the
Manager a revised list which has been certified either by the Customer or by a duly authorized
agent of the Customer. The Manager shall be entitled to rely upon any direction from, or document
signed by, any person listed in Appendix C of this Agreement. The Manager shall have no liability
in respect of fax transmission errors or interceptions of email communications by unauthorized
persons; provided, however, that any such interceptions do not occur due to grossly negligent
security measures of the Manager. The Manager shall be under no duty to make any investigation or
inquiry as to any statement contained in any writing and may accept the same as conclusive evidence
of the truth and accuracy of the statements therein contained.

8.3 Directions given by the Customer to the Manager shall be effective only upon actual
receipt by the Manager and shall be acknowledged by the Manager through its actions, unless the
Customer is advised by the Manager otherwise or unless the Customer requests otherwise in the text
of its directions.

9. Reports and Valuation. The Manager shall promptly provide the Customer with
written reports containing the valuations and status of the Account on a quarterly basis, or
otherwise as the Customer may from time to time reasonably request, except that written
confirmations of brokerage transactions shall be promptly sent solely to the Manager.

10. Non-Assignability. No assignment of this Agreement may be made by any party except
with the written consent of the Customer, provided that an assignment by operation of law shall not
require written consent unless required by applicable law. Subject to the foregoing, the provisions
of this Agreement shall be binding upon and shall inure to the benefit of and be enforceable by
each of the parties hereto and their respective successors and permitted assigns. The Customer will
be notified by the Manager of a change in general partners of the Manager within a reasonable time
thereafter.

11. Confidential Information. All proprietary client information of the Customer and
proprietary information and advice of the Manager (collectively, the “Information”) shall be
treated as confidential by the other party hereto and shall not be disclosed to the public by such
other party except (i) if such Information is or becomes available to the public or industry
sources other than as a result of disclosure by the receiving party or by someone known to such
party to have an obligation to keep such Information confidential; (ii) receiving party can
demonstrate that the Information was in its possession prior to the time of disclosure by the
disclosing party; (iii) the information is independently developed by or for the receiving party by
persons not having access to the Information hereunder; or (iv) the Information is, on the advice
of legal counsel, required to be disclosed by law or by legal process. Notwithstanding the
foregoing, if the receiving party receives a request to disclose all or any part of the Information
under a subpoena or other order issued by a court of competent jurisdiction or by a government
agency, the receiving party shall, if possible: (i) give the disclosing party prompt written
notice of such request; (ii) consult with the disclosing party on the advisability of taking
reasonable steps to resist or narrow that request and if disclosure of that Information is
required, furnish only such portion of the Information as the receiving party is advised by counsel
is legally required to be disclosed; and (iii) cooperate with the disclosing party, at the
disclosing party’s expense, in obtaining protective orders or undertakings that confidential
treatment will be afforded any of such Information so furnished. Notwithstanding the foregoing,
the Customer hereby consents to the disclosure by the Manager of the Customer’s name to brokers and
dealers (including, without limitation, any futures brokers and futures commission merchants if
futures are permitted by the Guidelines) whether executing or clearing, to carry out the Manager’s
activities on behalf of the Customer under this Agreement. Notwithstanding the foregoing, with the
prior written consent of the Customer, the Manager may disclose the Customer’s name to consultants
and prospective clients as part of a representative client list in connection with the compilation
of marketing materials.

The receiving party acknowledges and agrees that, in the event of any breach of this
Agreement, the disclosing party might be irreparably and immediately harmed and unable to be made
whole by monetary damages. It is accordingly agreed that the disclosing party, in addition to any
other remedy to which it may be entitled in law or equity, will be entitled to seek an injunction
or injunctions to remedy breaches of this agreement.

12. Remuneration. For its discretionary investment management services hereunder, the
Manager shall be entitled to the fees and terms of payment as set forth in Appendix B to this
Agreement, as the same may be amended from time to time by written agreement signed by the Manager
and the Customer. The Manager may, at its discretion, make payments out of such fees to any
Affiliate from which the Manager obtains assistance. Custodial fees, if any, are charged
separately by the Custodian for the Account and are not included in Appendix B unless specifically
set forth therein. The Customer shall be responsible for payment of brokerage commissions, transfer
fees, registration costs, taxes and other similar reasonable out of pocket costs and
transaction-related expenses and fees arising out of transactions in/management of the Account and
the Customer hereby authorizes the Manager to incur such expenses for the Account, provided that
any such expenses so incurred are disclosed in reasonable detail in reports contemplated by Section
9 hereof. All fees are exclusive of any value added or similar taxes which, if payable, shall be
payable by the Customer.

13. Services to Other Clients; Certain Affiliated Activities.

13.1 The relationship between the Manager and the Customer is as described in this Agreement
and permits, expressly as set forth herein, the Manager and its affiliates to effect transactions
with or for the Account in instances in which the Manager and its affiliates may have multiple
interests. In this regard the Customer understands that the Manager is part of a worldwide, full
service investment banking, broker-dealer, asset management organization, and as such,
the Manager and its affiliates (the “Firm”) and their managing directors, directors, officers and
employees (“Personnel”) may have multiple advisory, transactional and financial and other interests
in securities, instruments and companies that may be purchased, sold or held by the Manager for the
Account. The Firm may act as adviser to clients in investment banking, financial advisory, asset
management and other capacities related to instruments that may be purchased, sold or held in the
Account, and the Firm may issue, or be engaged as underwriter for the issuer of, instruments that
the Account may purchase, sell or hold. At times, these activities may cause departments of the
Firm to give advice to clients that may cause these clients to take actions adverse to the
interests of the Customer. The Firm and Personnel may act in a proprietary capacity with long or
short positions, in instruments of all types, including those that the Account may purchase, sell
or hold. Such activities could affect the prices and availability of the securities and
instruments that the Manager seeks to buy or sell for the Account, which could adversely impact the
performance of the Account. Personnel may serve as directors of companies the securities of which
the Account may purchase, sell, or hold. The Firm and Personnel may give advice, and take action,
with respect to any of the Firm’s clients or proprietary accounts that may differ from the advice
given, or may involve a different timing or nature of action taken, than with respect to any one or
all of the Manager’s accounts, and effect transactions for such clients or proprietary accounts at
prices or rates that may be more or less favorable than for the Account. The Firm and Personnel
may obtain and keep any profits, commissions and fees accruing to them in connection with other
activities for themselves and other clients and their own accounts and the Manager’s fees as set
forth in this Agreement shall not be abated thereby.

13.2 The Customer understands that the ability of the Manager and its affiliates to effect
and/or recommend transactions may be restricted by applicable regulatory requirements in the United
Kingdom, the European Union, the United States or elsewhere and/or their internal policies designed
to comply with such requirements. As a result, there may be periods when the Manager will not
initiate or recommend certain types of transactions in certain investments when the Manager or its
affiliates are performing investment banking or other services or when aggregated position limits
have been reached and the Customer will not be advised of that fact. Without limitation, when the
Manager or an affiliate is engaged in an underwriting or other distribution of securities of a
company, the Manager may in certain circumstances be prohibited from purchasing or recommending the
purchase of certain securities of that company for its clients.

13.3 The Customer should be aware that from time to time at the Manager’s discretion, advisory
Personnel may consult with Personnel in proprietary trading or other areas of the Firm or form
investment policy committees comprised of such Firm Personnel, and the performance of Firm
Personnel obligations related to their consultation with the Manager could conflict with their
areas of primary responsibility within the Firm. In connection with their activities with the
Manager, such Firm Personnel may receive information regarding the Manager’s proposed investment
activities which is not generally available to the public. However, there will be no obligation on
the part of such Firm Personnel to make available for use by investment management clients of the
Manager any information or strategies known to them or developed in connection with their client,
proprietary or other activities. In addition, the Firm will be under no obligation to make
available any research or analysis prior to its public dissemination. Furthermore, the Firm shall
have no obligation to recommend for purchase or sale by investment management accounts of the
Manager any security that the Firm or Personnel may purchase for themselves or for any other
clients. The Firm shall have no obligation to seek to obtain any material, non-public (“inside”)
information about any issuer of securities, and will not effect transactions for investment
management accounts of the Manager on the basis of any inside information as may come into its
possession.

13.4 In the event that the Manager is authorized to effect transactions in Derivatives
pursuant to the Guidelines, including contingent liability investments, it may settle or close out
such transactions without further reference to the Customer. The Manager may debit the Account
with any sums required to pay or supplement any deposit or margin support of such transaction.

14. Duration and Termination.

14.1 This Agreement may be terminated: (a) by either party upon 30 days’ prior written notice
at any time to the other party; (b) immediately by either party in the event of a material breach
by the other party of the terms of this Agreement and failure to cure such violation within 30 days
of becoming aware of, or receiving notice from, the other party of such violation; or (c) by the
Customer at any time with Cause (as defined below) or upon a Change in Control (as defined below)
of The Goldman Sachs Group, Inc. or the Manager. “Cause” shall mean (a) a willful violation by the
Manager of this Agreement or the Guidelines and (b) suspension of payments by the Manager of its
debts, entry by the Manager into an arrangement with its creditors, cessation of business by the
Manager, or threats by the Manager to cease carrying on its business, or the bankruptcy,
