obligation guaranteed by, or an interest in, the Seller or the Trustee or any
affiliate thereof. The Certificates are limited in right of payment, all as more
specifically set forth on the face hereof and in the Trust Agreement. All
payments or distributions made to Certificateholders under the Trust Agreement
shall be made only from the Trust Property and only to the extent that the
Trustee shall have sufficient income or proceeds from the Trust Property to make
such payments in accordance with the terms of the Trust Agreement. Each Holder

to the income and proceeds from the Trust Property to the extent available for

obligations, proceeds and duties evidenced hereby. A copy of the Trust Agreement

provided, the amendment thereof and the modification of the rights of the
Certificateholders under the Trust Agreement at any time by the Trustee with the
consent of the Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than a majority in interest in the Trust. Any such consent
by the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Trust Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

limitations therein set forth, the transfer of this Certificate is registerable
in the Register upon surrender of this Certificate for registration of transfer

Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same aggregate Fractional Undivided Interest in the Trust will be issued to
the designated transferee or transferees.

            The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of 1/300th% Fractional Undivided
Interest. As provided in the Trust Agreement and subject to certain limitations
therein set forth, Certificates are exchangeable for new Certificates of
authorized denominations evidencing the same aggregate Fractional Undivided
Interest in the Trust, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange, but the Trustee shall require payment of a sum sufficient to cover
any tax or governmental charge payable in connection therewith.

            sellers thereof set forth in such registration statement;

            copies of such registration statement, each amendment and supplement
            thereto (in each case including all exhibits), the prospectus
            included in such registration statement (including each preliminary

            such registration statement remains in effect, and do any and all
            other acts and things which may be reasonably necessary or advisable
            to enable such seller to consummate the disposition of the
            Registrable Certificates owned by such seller in such jurisdictions
            (PROVIDED, HOWEVER, that the Company will not

                                       3
<Page>

            be required to (A) qualify generally to do business in any
            jurisdiction where it would not otherwise be required to qualify but
            for this subparagraph, (B) consent to general service of process in
            any such jurisdiction or (C) subject itself to any taxation (other
            than stamp taxes) in any such jurisdiction);

      (v)   notify each seller of Registrable Certificates promptly after it
            shall receive notice thereof, of the time when such registration
            statement has become effective;

            request by the Commission for the amending or supplementing of such

            Certificates sold under the registration not later than the
            effective date of the registration statement;

     (viii) furnish to each Holder participating in the registration a signed
            counterpart, addressed to such Holder (a) of an opinion of counsel
            as to such matters that are customarily covered in an opinion of
            counsel delivered to an underwriter, including that the registration
            is valid and effective and such other matters as such Holder may
            reasonably request and (b) of a "cold comfort" letter signed by the
            independent public accountants who have issued a report on the
            Company's financial statements included in the registration
            statement, covering substantially the same matters with respect to
            such registration statement (and the prospectus included therein)
            and, in the case of such accountant's letter, with respect to events
            subsequent to the date of such financial statements, as are
            customarily delivered to underwriters in underwritten public
            offerings of securities and such other financial matters as such
            Holder may reasonably request;

      (ix)  advise each seller of such Registrable Certificates, promptly after
            it shall receive notice or obtain knowledge thereof, of the issuance
            of any stop order by the Commission suspending the effectiveness of
            such registration statement or of any order suspending or preventing
            the use of any related prospectus in any jurisdiction or the
            initiation or threatening of any proceeding for such purpose and
            promptly use its commercially reasonable efforts to prevent the
            issuance of any stop order or to obtain its withdrawal if such stop
            order should be issued;

      (x)   notify each seller of Registrable Certificates covered by such
            registration statement at any time when a prospectus relating
            thereto is required to be delivered under the Securities Act, upon
            discovery that, or upon the happening of any event as a result of
            which, the prospectus included in such registration statement, as
            then in effect, includes an untrue statement of a material fact or
            omits to state any material fact required to be stated therein or
            necessary to make the statements therein not misleading in the light
            of the circumstances under which they were made, and at the request
            of any such seller promptly prepare, file with the Commission and to
            furnish such seller a reasonable number of copies of a supplement to
            or an amendment of such prospectus as may be necessary so that, as
            thereafter delivered to the purchasers of such securities, such
            prospectus shall

                                       4
<Page>

            not include an untrue statement of a material fact required to be
            stated therein or necessary to make the statements therein not
            misleading in the light of the circumstances under which they were
            made;

      (xi)  otherwise use its reasonable efforts to comply with all applicable
            rules and regulations of the Commission, and make available to its

            more than eighteen months, beginning with the first full calendar
            month after the effective date of such registration statement, which
            earnings statement shall satisfy the provisions of Section 11(a) of
            the Securities Act, and Rule 158 promulgated thereunder and will
            furnish to each such seller at least two business days prior to the
            filing thereof a copy of any amendment or supplement to such
            registration statement or prospectus and shall not file any thereof
            to which any such seller shall have reasonably objected on the
            grounds that such amendment or supplement does not comply in all
            material respects with the requirements of the Securities Act or of
            the rules or regulations thereunder;

      (xii) enter into such customary agreements (excluding underwriting
            agreements) and take such other customary actions as the holders of
            Registrable Certificates shall reasonably request in order to
            expedite or facilitate the disposition of such Registrable
            Certificates;

     (xiii) make available for inspection by any seller of Registrable
            Certificates and any attorney, accountant or other agent retained by
            any such seller, all financial and other records, pertinent
            corporate documents and properties of such Person and cause its
            respective officers, directors, employees and independent
            accountants to supply all information reasonably requested by any
            such sellers, attorney, accountant or agent in connection with such
            registration statement;

      (xiv) deliver promptly to each Holder participating in an offering who so
            requests in writing the file correspondence and memoranda described
            below, copies of all correspondence between the Commission and such
            Person, its counsel or auditors with respect to the registration
            statement and permit each Holder to do such investigation, upon
            reasonable advance notice, with respect to information contained in
            or omitted from the registration statement as it deems reasonably
            necessary to comply with applicable securities laws or the rules and
            regulations of the National Association of Securities Dealers, Inc.
            ("NASD"). Such investigation shall include reasonable access to
            books, records and properties and opportunities to discuss the
            business of such Person with its officers and independent auditors,
            all to such reasonable extent and at such reasonable times and as
            often as any such Holder shall reasonably request;

      (xv)  permit any Holder of Registrable Certificates which Holder, in its
            reasonable judgment, might be deemed to be an underwriter or a
            controlling person of such Person, to participate in the preparation
            of such registration or comparable statement and to require the
            insertion therein of material, furnished to such Person

                                       5
<Page>

            in writing, which in the reasonable judgment of such holder and its
            counsel should be included; and

      (xvi) use its commercially reasonable efforts to cause such Registrable
            Certificates covered by such registration statement to be registered
            with or approved by such other governmental agencies or authorities
            as may be necessary to enable the sellers thereof to consummate the
            disposition of such Registrable Certificates.

If any such registration or comparable statement refers to any Holder by name or
otherwise as the Holder of any securities of the Company or the Trust and if, in
its reasonable judgment, such Holder is or might be deemed to be a controlling
person of the Company or the Trust, such Holder shall have the right to require
(i) the insertion therein of language, in form and substance reasonably
satisfactory to such Holder and presented to the Company in writing, to the
effect that the holding by such Holder of such securities is not to be construed
as a recommendation by such Holder of the investment quality of the Company's or
the Trust's securities covered thereby and that such holding does not imply that
such Holder will assist in meeting any future financial requirements of the
Company or the Trust, or (ii) in the event that such reference to such Holder by
name or otherwise is not required by the Securities Act or any similar Federal
statute then in force, the deletion of the reference to such Holder; provided
that with respect to this clause (ii) such Holder shall furnish to the Company
an opinion of counsel to such effect, which opinion and counsel shall be
reasonably satisfactory to the Company.

The Company may require each Holder of Registrable Certificates to be included
in such registration statement to promptly furnish in writing to the Company
such information regarding the distribution of the Registrable Certificates as
the Company may from time to time reasonably request and any such other
information as may be legally required in connection with such registration.

(b)   SUSPENSION OF DISPOSITIONS. Each Holder agrees by acquisition of any
      Registrable Certificates that, upon receipt of any notice (a "SUSPENSION
      NOTICE") from the Company of the happening of any event of the kind which,
      in the opinion of the Company, requires the amendment or supplement of any
      prospectus, such Holder will forthwith discontinue disposition of
      Registrable Certificates until such Holder's receipt of the copies of the
      supplemented or amended prospectus (which the Company shall prepare and
      file as promptly as practicable), or until it is advised in writing (the
      "ADVICE") by the Company that the use of the prospectus may be resumed,
      and such Holder has received copies of any additional or supplemental
      filings which are incorporated by reference in the prospectus, and, if so
      directed by the Company, such Holder will deliver to the Company all
      copies, other than permanent file copies then in such Holder's possession,
      of the prospectus covering such Registrable Certificates current at the
      time of receipt of such notice. In the event the Company shall give any
      such Suspension Notice or after the Demand Registration has become
      effective the offering of the Registrable Certificates pursuant to a
      registration is interfered with by any stop order, injunction, or other
      order or requirement of the Commission or other governmental agency or
      court (collectively, an "ORDER"), the time period regarding the
      effectiveness of registration statements ----- set forth in Section
      4(a)(ii) hereof shall be extended by the number of days (A) in the case of
      a Suspension Notice, during the period from and including the date of the
      giving of the

                                       6
<Page>

      Suspension Notice to and including the earlier to occur of (x) the date on
      which each seller of Registrable Certificates covered by such registration
      statement shall have received the copies of the supplemented or amended
      prospectus and (y) the date of the Advice and (B) in the case of an Order,
      during the period from and including the date of the Order to and
      including the date on which the Company advises all Holders in writing
      that the Order is no longer in effect..

(c)   REGISTRATION EXPENSES. All expenses incident to performance by the Company
      of or compliance with this Agreement including, without limitation, all
      registration and filing fees, invoiced reasonable fees and expenses of one
      legal counsel for all Holders of Registrable Certificates to be included
      in the registration statement, fees and expenses of compliance with
      securities or "blue sky" laws (including reasonable fees and disbursements
      of counsel in connection with "blue sky" qualifications of the Registrable
      Certificates), all word processing, duplicating and printing expenses
      (including expenses of printing certificates for the Registrable
      Certificates and of printing prospectuses if the printing of prospectuses
      is requested by a holder of Registrable Certificates), messenger and
      delivery expenses, fees and expenses of counsel for the Company and the
      respective independent certified public accountants (including the
      expenses of any special audit or "cold comfort" letters required by or

      Company elects to obtain such insurance), the fees and expenses of any
      special experts retained by the Company in connection with such
      registration, and the fees and expenses of other persons retained by the
      Company (all such expenses being herein called "REGISTRATION EXPENSES")
      will be borne by the Company whether or not any registration statement
      becomes effective; PROVIDED that in no event shall Registration Expenses
      include any underwriting discounts, commissions, or any out of pocket
      expenses of the Holders (or agents who manage their accounts) other than
      as expressly provided above.

(d)   FAILURE TO FILE DEMAND REGISTRATION. The Parties acknowledge and agree
      that, in the event that a Demand Registration is not filed on or prior to
      the Required Filing Date and/or such Demand Registration is not effective
      within two hundred seventy (270) days after the Required Filing Date,
      then: (a) Amtrak will pay such Additional Sub-Rent as is set forth in
      Sections 2.1 and 2.2 of the Facility Sublease pursuant to the terms
      thereof, and (b) the Borrower will pay such additional interest as is set
      forth in Section 2.2 of the Loan and Security Agreement, dated as of the
      date hereof, between the Company and the Borrower pursuant to the terms
      thereof.

5.    INDEMNIFICATION

(a)   The Company agrees to indemnify and hold harmless, to the fullest extent
      permitted by law, each seller of Registrable Certificates, and each of its
      employees, advisors, agents, representatives, partners, officers,
      directors and affiliates and each Person who controls such seller (within
      the meaning of the Securities Act or the Securities Exchange Act)
      (collectively, the "SELLER AFFILIATES") (i) against any and all losses,
      claims, damages, liabilities, and expenses, joint or several (including,
      without limitation, reasonable attorneys' fees except as limited by
      Section 5(c) below) arising out of or caused by any untrue or alleged
      untrue statement of a material fact contained in any registration

                                       7
<Page>

      statement, preliminary prospectus, final prospectus, summary prospectus,
      or any amendment thereof or supplement thereto if the Company shall have
      furnished any amendments or supplements, or any omission or alleged
      omission of a material fact required to be stated therein or necessary to
      make the statements therein, in light of the circumstances under which
      they were made, not misleading, (ii) against any and all loss, liability,
      claim, damage, and expense whatsoever, as incurred, to the extent of the
      aggregate amount paid in settlement of any litigation or investigation or
      proceeding by any governmental agency or body, commenced or threatened, or
      of any claim whatsoever based upon any such untrue statement or omission
      or alleged untrue statement or omission, and (iii) against any and all
      costs and expenses (including reasonable fees and disbursements of
      counsel) as may be reasonably incurred in investigating, preparing, or
      defending against any litigation, or investigation or proceeding by any
      governmental agency or body, commenced or threatened, or any claim
      whatsoever based upon any such untrue statement or omission or alleged
      untrue statement or omission, to the extent that any such expense or cost
      is not paid under subparagraph (i) or (ii) above; except insofar as the
      same are made in reliance upon and in strict conformity with information
      furnished in writing to the Company by such seller or any Seller Affiliate
      for use therein. The reimbursements required by this Section 5(a) will be
      made by periodic payments during the course of the investigation or
      defense, as and when bills are received or expenses incurred.

(b)   In connection with any registration statement in which a seller of
      Registrable Certificates is participating, each such seller will furnish
      to the Company in writing such information and affidavits as the Company
      reasonably requests for use in connection with any such registration
      statement or prospectus and, to the fullest extent permitted by law, each
      such seller will indemnify the Company, its directors, agents, officers
      and each Person who controls the Company (within the meaning of Section 15
      of the Securities Act or Section 20 of the Securities Exchange Act) or the
      Company to the same extent as the foregoing indemnity from the Company to
      the selling Holders, but only to the extent that such untrue statement or
      alleged untrue statement or omission or alleged omission is contained in
      any information or affidavit so furnished in writing by such seller or any
      of its Seller Affiliates for specific inclusion in such registration
      statement; provided that the obligation to indemnify will be several, not
      joint and several, among such sellers of Registrable Certificates, and the
      liability of each such seller of Registrable Certificates will be in
      proportion to, and provided further that such liability will be limited
      to, the net amount received by such seller from the sale of Registrable
      Certificates pursuant to such registration statement.

(c)   Any Person entitled to indemnification hereunder will (i) give prompt
      written notice to the indemnifying party of any claim with respect to
      which it seeks indemnification (provided that the failure to give such
      notice shall not limit the rights of such Person, unless such Person is
      materially adversely affected by a failure to receive such written notice)
      and (ii) unless in such indemnified party's reasonable judgment a conflict
      of interest between such indemnified and indemnifying parties may exist
      with respect to such claim, permit such indemnifying party to assume the
      defense of such claim with counsel reasonably satisfactory to the
      indemnified party; PROVIDED, HOWEVER, that any person entitled to
      indemnification hereunder shall have the right to employ separate

                                       8
<Page>

      counsel and to participate in the defense of such claim, but the fees and
      expenses of such counsel shall be at the expense of such person unless (X)
      the indemnifying party has agreed to pay such fees or expenses, (Y) the
      indemnifying party shall have failed to assume the defense of such claim
      and employ counsel reasonably satisfactory to such person or (Z) in the
      reasonable judgment of any indemnified party, a conflict of interest may
      exist between such indemnified party and any other of such indemnified
      parties with respect to such claim. An indemnifying party will not be
      obligated to pay the fees and expenses of more than one counsel for all
      parties indemnified by such indemnifying party with respect to such claim.
      If such defense is assumed by the indemnified party as permitted
      hereunder, the indemnifying party will not be subject to any liability for
      any settlement made by the indemnified party without the written consent
      (which consent shall not be unreasonably withheld) of the indemnifying
      party. If such defense is assumed by the indemnifying party pursuant to
      the provisions hereof, such indemnifying party shall not settle or
      otherwise compromise the applicable claim unless (1) such settlement or
      compromise contains a full and unconditional release of the indemnified
      party from all liabilities arising out of such proceeding or (2) the
      indemnified party otherwise consents in writing.

(d)   Each Party hereto agrees that, if for any reason the indemnification
      provisions contemplated by Section 5(a) or Section 5(b) are unavailable to
      or insufficient to hold harmless an indemnified party in respect of any
      losses, claims, damages, liabilities, or expenses (or actions in respect
      thereof) referred to therein, then each indemnifying party shall
      contribute to the amount paid or payable by such indemnified party as a
      result of such losses, claims, liabilities, or expenses (or actions in
      respect thereof) in such proportion as is appropriate to reflect the
      relative fault of the indemnifying party and the indemnified party as well
      as any other relevant equitable considerations. The relative fault of such
      indemnifying party and indemnified party shall be determined by reference
      to, among other things, whether the untrue or alleged untrue statement of
      a material fact or omission or alleged omission to state a material fact
      relates to information supplied by such indemnifying party or indemnified
      party, and the parties' relative knowledge, access to information and
      opportunity to correct or prevent such statement or omission. The Parties
      hereto agree that it would not be just and equitable if contribution
      pursuant to this Section 5(d) were determined by pro rata allocation (even
      if the Holders were treated as one entity for such purpose) or by any
      other method of allocation which does not take account of the equitable
      considerations referred to in this Section 5(d). The amount paid or
      payable by an indemnified party as result of the losses, claims, damages,
      liabilities, or expenses (or actions in respect thereof) referred to above
      shall be deemed to include any legal or other fees or expenses reasonably
      incurred by such indemnified party in connection with investigating or,
      except as provided in Section 5(c), defending any such action or claim.
      Notwithstanding the provisions of this Section 5(d), no Holder shall be
      required to contribute an amount greater than the dollar amount of the net
      proceeds received by such Holder with respect to the sale of any
      Registrable Certificates. No person guilty of fraudulent misrepresentation
      (within the meaning of Section 11(f) of the Securities Act) shall be
      entitled to contribution from any person who was not guilty of such
      fraudulent misrepresentation. The Holders' obligations in this Section
      5(d) to contribute shall be several in proportion to the amount of
      Registrable Certificates registered by them and not joint.

                                       9
<Page>

(e)   The indemnification provided for under this Agreement will remain in full
      force and effect regardless of any investigation made by or on behalf of
      the indemnified party or any officer, director or controlling Person of
      such indemnified party and will survive the transfer of securities.

6.    REPRESENTATIONS AND WARRANTIES

            Subsidiaries, taken as a whole.

            enforceability of creditors' rights generally and the application of
            general principles of equity and except as the enforceability of the
            indemnification provisions in this Agreement may be limited by
            applicable state and federal securities laws.

      (iii) The execution, delivery, and performance of this Agreement by the
            Company shall not, by the lapse of time, the giving of notice or
            otherwise, constitute a violation of any applicable statute, law,
            rule or regulation of any governmental authority, any applicable
            provision contained in the articles of incorporation or bylaws of
            the Company or contained in any agreement, instrument, or document
            to which the Company is a party or by which it is bound, or any
            order, ruling, judgment or decree of any court, arbitral body or

      quarterly report of the Company, and such other reports and documents so
      filed by the Company as such Holder may reasonably request availing itself
      of any rule or regulation of the Commission allowing such Holder to sell
      any Registrable Certificates without registration.

13.   MODIFICATION

      Except as otherwise provided herein, neither this Agreement nor any
provision hereof can be amended, modified, changed, discharged, waived or
terminated (each, an "AMENDMENT") except by an instrument in writing executed by
the Company and the Trustee on behalf of the Holders, at the time of
determination, of a majority of Fractional Undivided Interest of the Registrable

Parties in accordance with its terms, PROVIDED, that no such Amendment shall (i)
amend the threshold of Registrable Certificates required to effect a Demand
Registration pursuant to Section 2(a), or (ii) amend the provisions of Section
8, 9 or this Section 13, unless such Amendment has been unanimously approved by
all Holders.

14.   WAIVER

      Any waiver by any Party of a breach of any provision of this Agreement
shall not operate as or be construed to be a waiver of any other breach of that
provision or of any breach of any other provision of this Agreement. The failure
of a Party to insist upon strict adherence to any term of this Agreement on one
or more occasions shall not be considered a waiver or deprive that Party of the
right thereafter to insist upon strict adherence to that term or any other term
of this Agreement. Subject to the provisions of Section 13 hereof, any waiver
must be evidenced by a writing signed by the Party against whom the waiver is
sought to be enforced.

15.   AVAILABILITY OF EQUITABLE REMEDIES

      Each Party acknowledges that a breach of the provisions of this Agreement
could not adequately be compensated by money damages. Accordingly, it is the
intention of the Parties that any Party shall be entitled, in addition to any
other right or remedy available to it, to an injunction restraining such breach
or a threatened breach and/or to specific performance of any such provision of
this Agreement, and in either case no bond or other security shall be required
in connection therewith, and the Parties hereby consent to such injunction and
to the ordering of specific performance.

16.   ENTIRE AGREEMENT

      This Agreement, together with the Trust Agreement and the Certificate
Purchase Agreement and the Mortgage Documents with respect to those Parties
hereto that are parties thereto as well, sets forth the entire understanding,
and supersedes all prior agreements and understandings, both written and oral,
among the Parties with respect to the subject matter hereof.

17.   SEVERABILITY

      If any provision of this Agreement shall be determined to be illegal or
unenforceable by any court of law of competent jurisdiction, the Parties intend
that such provision shall be deemed not to form part of this Agreement and, the
remaining provisions shall be severable and enforceable in accordance with their
terms.
