Securities (as defined herein) of Interpool Capital Trust, a Delaware statutory
business trust (the "Issuer").

                  WHEREAS, pursuant to an Amended and Restated Declaration of

                          OF CAPITAL GUARANTEE TRUSTEE


SECTION 3.1       Powers and Duties of the Capital Guarantee Trustee

Capital Guarantee Trustee shall exercise such of the rights and powers vested in
it by this Capital Securities Guarantee, and use the same degree of care and
skill in its exercise thereof, as a prudent individual would exercise or use
under the circumstances in the conduct of his or her own affairs.

<PAGE>   9
                  (d) No provision of this Capital Securities Guarantee shall be
construed to relieve the Capital Guarantee Trustee from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                           (i) prior to the occurrence of any Event of Default
of which a Responsible Officer of the Capital Guarantee Trustee has actual
knowledge, and after the curing or waiving of all such Events of Default that
may have occurred:

(A) the duties and obligations of the Capital Guarantee Trustee shall be
determined solely by the express provisions of this Capital Securities
Guarantee, and the Capital Guarantee Trustee shall not be liable except for the
performance of such duties and obligations as are specifically set forth in this
Capital Securities Guarantee, and no implied covenants or obligations shall be
read into this Capital Securities Guarantee against the Capital Guarantee
Trustee; and

(B) in the absence of bad faith on the part of the Capital Guarantee Trustee,
the Capital Guarantee Trustee may conclusively rely, as to the truth of the

certificates or opinions furnished to the Capital Guarantee Trustee and
conforming to the requirements of this Capital Securities Guarantee; but in the
case of any such certificates or opinions that by any provision hereof are
specifically required to be furnished to the Capital Guarantee Trustee, the
Capital Guarantee Trustee shall be under a duty to examine the same to determine
whether or not they conform to the requirements of this Capital Securities
Guarantee;

                           (ii) the Capital Guarantee Trustee shall not be
liable for any error of judgment made in good faith by a Responsible Officer of
the Capital Guarantee Trustee, unless it shall be proved that the Capital
Guarantee Trustee was negligent in ascertaining the pertinent facts upon which
such judgment was made;

                           (iii) the Capital Guarantee Trustee shall not be
liable with respect to any action taken or omitted to be taken by it in good
faith in accordance with the direction of the Holders of not less than a
Majority in liquidation amount of the Capital Securities relating to the time,
method and place of conducting any proceeding for any remedy available to the
Capital Guarantee Trustee, or exercising any trust or power conferred upon the
Capital Guarantee Trustee under this Capital Securities Guarantee; and

                           (iv) no provision of this Capital Securities
Guarantee shall require the Capital Guarantee Trustee to expend or risk its own
funds or otherwise incur personal financial liability in the performance of any
of its duties or in the exercise of any of its rights or powers, if the Capital
Guarantee Trustee shall have reasonable grounds for believing that the repayment
of such funds or liability is not reasonably assured to it under the terms of
this Capital Securities Guarantee or indemnity, reasonably satisfactory to the
Capital Guarantee Trustee, against such risk or liability is not reasonably
assured to it.

Trustee or its agents hereunder shall bind the Holders of the Capital
Securities, and the signature of the Capital Guarantee Trustee or its agents
alone shall be sufficient and effective to perform any such action. No third
party shall be required to inquire as to the authority of the Capital Guarantee
Trustee to so act or as to its compliance with any of the terms and provisions
of this Capital Securities Guarantee, both of which shall be conclusively
evidenced by the Capital Guarantee Trustee's or its agent's taking such action.

                           (x) Whenever in the administration of this Capital
Securities Guarantee the Capital Guarantee Trustee shall deem it desirable to
receive instructions with respect to enforcing any remedy or right or taking any
other action hereunder, the Capital Guarantee Trustee (i) may request
instructions from the Holders of a Majority in liquidation amount of the
Securities, (ii) may refrain from enforcing such remedy or right or taking such
other action until such instructions are received, and (iii) shall be protected
in conclusively relying on or acting in accordance with such instructions.

                           (xi) The Capital Guarantee Trustee shall not be
liable for any action taken, suffered, or omitted to be taken by it in good
faith and reasonably believed by it to be authorized or within the discretion or
rights or powers conferred upon it by this Capital Securities Guarantee.

                  (b) No provision of this Capital Securities Guarantee shall be
deemed to impose any duty or obligation on the Capital Guarantee Trustee to
perform any act or acts or exercise any right, power, duty or obligation
conferred or imposed on it in any jurisdiction in which it shall be illegal, or
in which the Capital Guarantee Trustee shall be unqualified or incompetent in
accordance with applicable law, to perform any such act or acts or to exercise
any such right, power, duty or obligation. No permissive power or authority
available to the Capital Guarantee Trustee shall be construed to be a duty.

on the Debentures or any extension of the maturity date of the Debentures
permitted by the Indenture);

                  (c) any failure, omission, delay or lack of diligence on the
part of the Holders to enforce, assert or exercise any right, privilege, power

extension of any kind;

                  (d) the voluntary or involuntary liquidation, dissolution,
sale of any collateral, receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment

shall be absolute and unconditional under any and all circumstances.

                  There shall be no obligation of the Holders or the Capital
Guarantee Trustee to give notice to, or obtain consent of, the Guarantor with
respect to the happening of any of the foregoing.

SECTION 5.4       Rights of Holders

                  (a) The Holders of a Majority in liquidation amount of the

legal proceeding directly against the Guarantor to enforce the Capital Guarantee
Trustee's rights under this Capital Securities Guarantee, without first

any action be brought first against the Issuer, the Capital Guarantee Trustee or
any other Person before proceeding directly against the Guarantor.

the Issuer) or upon distribution of the Debentures to the Holders of the Capital
Securities as provided in the Declaration.

SECTION 5.6       Subrogation

                  The Guarantor shall be subrogated to all (if any) rights of
the Holders of Capital Securities against the Issuer in respect of any amounts
paid to such Holders by the Guarantor under this Capital Securities Guarantee;
provided, however, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any right
that it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Capital
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Capital Securities Guarantee. If any amount shall be paid
to the Guarantor in violation of the preceding sentence, the Guarantor agrees to
hold such amount in trust for the Holders and to pay over such amount to the
Holders.

SECTION 5.7       Independent Obligations

independent of the obligations of the Issuer with respect to the Capital
Securities, and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Capital
Securities Guarantee notwithstanding the occurrence of any event referred to in
subsections (a) through (g), inclusive, of Section 5.3 hereof.

                  This Capital Securities Guarantee will constitute an unsecured
obligation of the Guarantor and will rank (i) subordinate and junior in right of
payment to all Senior Indebtedness, in the same manner and to the same extent as
provided in the Indenture with respect to the Debentures, except in the case of
a bankruptcy or insolvency proceeding in respect of the Guarantor, in which case
