          (II) insofar as perfection of such security interest can be
          accomplished only by filing financing statements under the Uniform
          Commercial Code in [list filing offices and jurisdictions], upon the
          filing of such financing statements in such filing offices,


<PAGE>


                                                                              17

          the Bond Trustee will have a perfected security interest in such
          Collateral, and (III) when so perfected, the Bond Trustee's security
          interest in such Collateral as to which perfection of such security
          interest can be accomplished only by filing a financing statement will
          have priority over any other security interest in such Collateral if
          such other security interest, in order to achieve priority over the
          Bond Trustee's security interest by the filing of one or more
          financing statements, was required by law to have been perfected by
          making such filings in the filing offices prior to the effective date
          of [describe search reports and effective date]; and

               (xii) the Issuer is not and, after giving effect to the offering
          and sale of the Securities and the application of the proceeds thereof
          as described in the Prospectus, will not be an "investment company" or
          under the "control" of an "investment company" as such terms are
          defined under the Investment Company Act of 1940, as amended.

          (d) The Representative shall have received from Cravath, Swaine &
     Moore, counsel for the Underwriters, such opinion or opinions, dated the
     Time of Delivery, with respect to the issuance and sale of the Securities,
     the Indenture, the Registration Statement, the Prospectus (together with
     any supplement thereto) and other related matters as the Representative may
     reasonably require, and each of the Company and the Issuer shall have
     furnished to such counsel such documents as they request for the purpose of
     enabling them to pass upon such matters.

          (e) The Representative shall have received a certificate of the
     Company, signed by any Vice President of the Company, dated the Time of
     Delivery, in form and substance reasonably satisfactory to the
     Representative, to the effect that the signer of such certificate has
     reviewed the Registration Statement, the Prospectus, any supplement to the
     Prospectus and this Agreement and that:

               (i) the representations and warranties of the Company and the
          Issuer in this Agreement, the Sale Agreement and the Servicing
          Agreement are true and correct in all material respects on and as of
          the Time of Delivery with the same effect as if made at the Time of
          Delivery, and the Company and the Issuer have complied with all the
          agreements and satisfied all the conditions on their respective


<PAGE>


                                                                              18

          parts to be performed or satisfied at or prior to the Time of
          Delivery;

               (ii) no stop order suspending the effectiveness of the
          Registration Statement has been issued and no proceedings for that
          purpose have been instituted or, to the Company's knowledge,
          threatened; and

               (iii) since the dates as of which information is given in the
          Prospectus (exclusive of any supplement thereto), there has been no
          material adverse change in the condition (financial or other),
          earnings, business or properties of the Company and its Subsidiaries
          taken as a whole (if such a change would impair the investment quality
          of the Securities or make it impractical or inadvisable to market the
          Securities) or the Issuer, whether or not arising from transactions in
          the ordinary course of business, except as set forth in or
          contemplated in the Prospectus (exclusive of any supplement thereto).

          (f) At the Time of Delivery, the Representative shall have received
     from PricewaterhouseCoopers LLP (i) a letter or letters (which may refer to
     letters previously delivered to one or more of the Representative), dated
     as of the Time of Delivery, in form and substance satisfactory to the
     Representative, confirming that they are independent accountants within the
     meaning of the Act and the Exchange Act and the respective applicable
     published rules and regulations thereunder and stating in effect that they
     have performed certain specified procedures as a result of which they
     determined that certain information of an accounting, financial or
     statistical nature (which is limited to accounting, financial or
     statistical information derived from the general accounting records of the
     Company and its Subsidiaries) set forth in the Registration Statement and
     the Prospectus, including information specified by the Underwriters and set
     forth under the captions "Prospectus Summary," "PECO Energy's Restructuring
     Plan," "The Qualified Rate Orders And The Intangible Transition Charges,"
     "The Seller and Servicer," and "The Transition Bonds" in the Prospectus,
     agrees with the accounting records of the Company and its Subsidiaries,
     excluding any questions of legal interpretation, and (ii) the opinion or
     certificate, dated as of the Time of Delivery, in form and substance
     satisfactory to the Representative, satisfying the requirements of Section
     2.10(7) of the Indenture.


<PAGE>


                                                                              19

          References to the Prospectus in this clause (f) include any supplement
     thereto at the date of the letter.

          In addition, except as provided in Schedule I hereto, at the Execution
     Time, the Representative shall have received from PricewaterhouseCoopers
     LLP a letter or letters, dated as of the Execution Time, in form and
     substance satisfactory to the Representative, to the effect set forth
     above.

          (g) Subsequent to the Execution Time or, if earlier, the dates as of
     which information is given in the Registration Statement (exclusive of any
     amendment thereof) and the Prospectus (exclusive of any supplement
     thereto), and at or prior to the Time of Delivery, there shall not have
     been any change, or any development involving a prospective change, in or
     affecting either (i) the business or properties or financial condition of
     the Company or the Issuer, or (ii) the Intangible Transition Property, the
     Securities, the Qualified Rate Orders or the Statute, the effect of which
     is, in the judgment of the Representative, so material and adverse as to
     make it impractical or inadvisable to proceed with the offering or delivery
     of the Securities as contemplated by the Registration Statement (exclusive
     of any amendment thereof) and the Prospectus (exclusive of any supplement
     thereto).

          (h) The Representative, the Company and the Issuer shall have received
     on the Closing Date an opinion letter or letters of Ballard Spahr Andrews &
     Ingersoll, counsel to the Company and the Issuer, dated the Time of
     Delivery, in form and substance reasonably satisfactory to the
     Representative, (i) with respect to the characterization of the transfer of
     the Intangible Transition Property by the Company to the Issuer as a "true
     sale" for bankruptcy purposes, (ii) to the effect that a court would not
     order the substantive consolidation of the assets and liabilities of the
     Issuer with those of the Company in the event of a bankruptcy,
     reorganization or other insolvency proceeding involving the Company and
     (iii) to the effect that upon the delivery of the fully executed Sale
     Agreement to the Issuer and the payment of the purchase price of the
     Intangible Transition Property by the Issuer to the Seller pursuant to the
     Sale Agreement, then (A) the transfer of the Intangible Transition Property
     by the Seller to the Issuer pursuant to the Sale Agreement conveys the
     Seller's right, title and interest in the Intangible Transition Property to
     the Issuer and will be treated as an absolute transfer of all the Seller's
     right, title and


<PAGE>


                                                                              20

     interest in the Intangible Transition Property, other than for federal and
     state tax purposes, (B) such transfer of the Intangible Transition Property
     is perfected, (C) such transfer has priority over any other assignment of
     the Intangible Transition Property, and (D) the Intangible Transition
     Property is free and clear of all liens created prior to its transfer to
     the Issuer pursuant to the Sale Agreement.

          (i) At or prior to the Time of Delivery, the Representative shall have
     received evidence, in form and substance reasonably satisfactory to the
     Representative, that the Company has obtained a release of the Intangible
     Transition Property from the lien of that certain mortgage, dated May 1,
     1923, as supplemented and amended to the date hereof, between the Company
     and First Union Trust Company, National Association (as successor to
     Fidelity Trust Company), as trustee.

          (j) The Securities shall have been rated in the highest long-term
     rating category by each of the Rating Agencies or in such other rating
     category as was specified in the Preliminary Prospectus.

          (k) At or prior to the Time of Delivery, the Representative shall have
     received evidence, in form and substance reasonably satisfactory to the
     Representative, that appropriate filings have been or are being made in
     accordance with the Statute and other applicable law reflecting the grant
     of a security interest by the Issuer in the Collateral to the Bond Trustee.

          (l) At or prior to the Time of Delivery, the Representative shall have
     received evidence of the Pennsylvania Public Utility Commission's approval
     of the Qualified Rate Orders.

          (m) Prior to the Time of Delivery, each of the Company and the Issuer
     shall have furnished to the Representative such further information,
     certificates, opinions and documents as the Representative may reasonably
     request and as are customary for transactions of this type.

          (n) The Representative shall have received an opinion of counsel to
     the Bond Trustee, dated the Time of Delivery, in form and substance
     reasonably satisfactory to the Representative, to the effect that:

               (i) the Bond Trustee is a New York banking association in good
          standing under the laws of the State of New York;


<PAGE>


                                                                              21

               (ii) the Indenture has been duly authorized, executed and
          delivered, and constitutes a legal, valid and binding instrument
          enforceable against the Bond Trustee in accordance with its terms
          (subject, as to enforcement of remedies, to applicable bankruptcy,
          reorganization, insolvency, moratorium or other similar laws or
          equitable principles affecting creditors' rights generally from time
          to time in effect); and

               (iii) the Securities have been duly authenticated by the Bond
          Trustee.

          (o) The Representative shall have received an opinion of counsel to
     the Issuer Trustee, dated the Time of Delivery, in form and substance
     reasonably satisfactory to the Representative, to the effect that:

               (i) the Issuer Trustee has been duly incorporated and is validly
          existing as a national banking association in good standing under the
          federal laws of the United States of America, with full corporate
          trust power and authority to enter into and perform its obligations
          under the Trust Agreement; and

               (ii) the Trust Agreement has been duly authorized, executed and
          delivered by the Issuer, and constitutes a legal, valid and binding
          instrument enforceable against the Issuer in accordance with its terms
          (subject, as to enforcement of remedies, to applicable bankruptcy,
          reorganization, insolvency, moratorium or other laws affecting
          creditors' rights generally from time to time in effect).


     This Agreement and all obligations of the Underwriters hereunder may be
canceled at, or at any time prior to, the Time of Delivery by the Representative
if any of the conditions specified in this Section 7 shall not have been
fulfilled in all material respects when and as provided in this Agreement.
Notice of such cancelation shall be given to the Company in writing or by
telephone or telegraph confirmed in writing.

     The documents required to be delivered by this Section 7 shall be delivered
at the office of Ballard Spahr Andrews & Ingersoll, LLP, counsel for the
Company, at 1735 Market Street, 51st Floor, Philadelphia, PA 19103-7599, at the
Time of Delivery.

     8. Indemnification and Contribution. (a) The Company agrees to indemnify
and hold harmless each


<PAGE>


                                                                              22

Underwriter, the directors, officers, employees and agents of each Underwriter
and each person who controls any Underwriter within the meaning of either
Section 15 of the Act or Section 20 of the Exchange Act from and against any and
all losses, claims, damages, liabilities and expenses, based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus contained therein and including
any amendment or supplement to any thereof) or any omission or alleged omission
to state therein 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; provided, however, that the Company will not be liable in
any such case to the extent that any such losses, claims, damages, liabilities
or expenses are caused by (i) any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company or the Issuer by or
on behalf of any Underwriter through the Representative specifically for
inclusion therein, or (ii) the failure of any Underwriter to send to any
purchaser to whom it had sent a Preliminary Prospectus an amended Prospectus as
shall have been furnished by the Company within the time periods required by the
Act and in such quantities are required by each Underwriter for such purpose
(excluding documents incorporated therein by reference), if required by the Act,
to the extent that the amended prospectus would have cured the defect in the
Preliminary Prospectus giving rise to such losses, claims, damages or
liabilities, or (iii) any use of the Prospectus by any Underwriter after the
expiration of that period, if any, during which the Underwriter is required by
law to deliver a prospectus, unless the Company shall have been advised in
writing of such intended use. This indemnity agreement will be in addition to
any liability which the Company may otherwise have.

     (b) Each Underwriter severally and not jointly agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers who signs the
Registration Statement, and each person who controls the Company within the
meaning of either the Act or the Exchange Act, the Issuer and each of its
controlling persons and trustees to the same extent as the foregoing indemnity
from the Company to each Underwriter, but only with reference to written
information relating to such Underwriter furnished to the Company by or on
behalf of such Underwriter through the Representative specifically for inclusion
in the documents referred to in the foregoing indemnity. This indemnity
agreement will be in addition to any liability which any Underwriter may
otherwise have. The Company acknowledges that the statements set forth in the
last paragraph of the cover page of the Prospectus Supplement and the Prospectus
and the information set forth under the


<PAGE>


                                                                              23

heading "Underwriting the Series 2000-A Bonds" in the Prospectus Supplement and
"Plan of Distribution" in the Prospectus constitute the only information
furnished in writing by or on behalf of the several Underwriters for inclusion
in the documents referred to in the foregoing indemnity.

     (c) If any action, suit or proceeding shall be brought against any
Underwriter or any person controlling any Underwriter in respect of which
indemnity may be sought against the Company, such Underwriter or such
controlling person shall promptly notify the Company and the Company shall
assume the defense thereof, including the employment of counsel and payment of
all fees and expenses. Such Underwriter or any such controlling person shall
have the right to employ separate counsel in any such action, suit or proceeding
and to participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of such Underwriter or such controlling person
unless (i) the Company has agreed in writing to any such fees and expenses, (ii)
the Company has failed, within 30 days after the Company has been so notified,
to assume the defense and employ counsel, or (iii) the named parties to any such
action, suit or proceeding (including any impleaded parties) include both such
Underwriter or such controlling person and the Company and such Underwriter or
such controlling person shall have been advised by its counsel that
representation of such indemnified party and the Company by the same counsel
would be inappropriate under applicable standards of professional conduct
(whether or not such representation by the same counsel has been proposed) due
to actual or potential differing interests or defenses among them (in which case
the Company shall not have the right to assume the defense of such action, suit
or proceeding on behalf of such Underwriter or such controlling person). It is
understood, however, that the Company shall, in connection with any one such
action, suit or proceeding or separate but substantially similar or related
actions, suits or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of only one separate firm of attorneys (in addition to any local
counsel) at any time for all such Underwriters and controlling persons not
having actual or potential differing interests or defenses with you or among
themselves, which firm shall be designated in writing by the Representative, and
that all such fees and expenses shall be reimbursed as they become due. The
Company shall not be liable for any settlement of any such action, suit or
proceeding effected without their written consent, but if settled with such
written consent, or if there be a final judgment for the plaintiff in any such
action, suit or proceeding, the Company agrees to indemnify and hold harmless
any Underwriter, to the extent provided in the preceding paragraph, and any such
controlling person


<PAGE>


                                                                              24

from and against any loss, claim, damage, liability or expense by reason of such
settlement or judgment.

     (d) If the indemnification provided for in this Section 8 is for any reason
held to be unenforceable by an indemnified party although applicable in
accordance with its terms (including the terms of subsection (b) of this Section
8), an indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses in such proportion as
is equitable and as shall reflect both the relative benefit received by the
Issuer and the Company on the one hand and the Underwriter or Underwriters, as
the case may be, on the other hand, from the offering of the Securities, and the
relative fault, if any, of the Issuer and the Company on the one hand and of the
Underwriter or Underwriters, as the case may be, on the other hand in connection
with the statements or omissions which resulted in such losses, liabilities,
claims, damages or expenses, as well as any other relevant equitable
considerations. The relative benefit received by the Issuer and the Company on
the one hand and the Underwriters or Underwriters, as the case may be, on the
other hand, in connection with the offering of the Securities shall be deemed to
be in the same proportion as the total net proceeds from the offering of the
Securities (before deducting expenses) received by the Issuer and the Company
bear to the total commissions, concessions and discounts received by the
Underwriter or Underwriters, as the case may be. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Issuer and the Company on
the one hand, or the Underwriter or Underwriters, as the case may be, on the
other hand, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Company
and the Underwriters agree that it would not be just and equitable if
contribution pursuant to this Section 8 were determined by a pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation that does not take account of the equitable
considerations referred to above. The amount paid or payable by an indemnified
party as a result of the losses, liabilities, claims, damages and expenses
referred to above shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price of the Securities underwritten by it and distributed to the


<PAGE>


                                                                              25

public exceeds the amount of any damages which such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute pursuant to this
Section 8 are several in proportion to the respective principal amounts of
Securities set forth opposite their names in Schedule I hereto and not joint.

     (e) No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened action,
suit or proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.

     (f) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 8 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses become due. A successor to
any Underwriter or any person controlling any Underwriter, or to the Issuer or
the Company, their directors or officers, or any person controlling the Issuer
or the Company, shall be entitled to the benefits of the indemnity, contribution
and reimbursement agreements contained in this Section 8.

     9. If any one or more Underwriters shall fail to purchase and pay for any
of the Securities agreed to be purchased by such Underwriter or Underwriters
hereunder and such failure to purchase shall constitute a default in the
performance of its or their obligations under this Agreement, the nondefaulting
Underwriters shall be obligated severally to take up and pay for (in the
respective proportions which the amount of Securities set forth opposite their
names in Schedule II hereto bears to the aggregate amount of Securities set
forth opposite the names of all the remaining Underwriters) the Securities which
the defaulting Underwriter or Underwriters agreed but failed to purchase;
provided, however, that in the event that the aggregate amount of Securities
which the defaulting Underwriter or Underwrites agreed but failed to purchase
shall exceed 10% of the aggregate amount of Securities set forth in Schedule II
hereto, the nondefaulting Underwriters shall have the right to purchase all, but
shall not be under any obligation to purchase any, of the Securities, and if
such nondefaulting Underwriters do not purchase all the


<PAGE>


                                                                              26

Securities, this Agreement will terminate without liability to any nondefaulting
Underwriter, the Issuer or the Company. In the event of a default by any
Underwriter as set forth in this Section 9, the Time of Delivery shall be
postponed for such period, not exceeding seven days, as the Representative shall
determine in order that the required changes in the Registration Statement and
the Prospectus or in any other documents or arrangements may be effected.
Nothing contained in this Agreement shall relieve any defaulting Underwriter of
its liability, if any, to the Company, the Issuer and any nondefaulting
Underwriter for damages occasioned by its default hereunder.

     10. This Agreement shall be subject to termination in the absolute
discretion of the Representative, by notice given to the Company prior to
delivery of and payment for the Securities, if at any time prior to such time
(i) there shall have occurred any change, or any development involving a
prospective change, in or affecting either (A) the business, properties or
financial condition of the Company (if such a change or development would, in
the judgment of the Representative, impair the investment quality of the
Securities or make it impractical or inadvisable to market the Securities) or
the Issuer or (B) the Intangible Transition Property, the Securities, the
Qualified Rate Orders or the Statute, the effect of which, in the judgment of
the Representative, materially impairs the investment quality of the Securities
or makes it impractical or inadvisable to market the Securities, (ii) trading in
the Company's Common Stock shall have been suspended by the Commission or the
New York Stock Exchange (if such a suspension would, in the judgment of the
Representative, impair the investment quality of the Securities or make it
impractical or inadvisable to market the Securities) or trading in securities
generally on the New York Stock Exchange shall have been suspended or limited or
minimum prices shall have been established on such Exchange, (iii) a banking
moratorium shall have been declared by Federal, New York State or Pennsylvania
State authorities or (iv) there shall have occurred any outbreak or escalation
of hostilities, declaration by the United States of a national emergency or war
or other calamity or crisis the effect of which on financial markets is such as
to make it, in the judgment of the Representative, impracticable or inadvisable
to proceed with the offering or delivery of the Securities as contemplated by
the Final Prospectus (exclusive of any supplement thereto).

     11. If the sale of the Securities provided for herein is not consummated
because any condition to the obligations of the Underwriters set forth in
Section 7 hereof is not satisfied, because of any termination pursuant to
Section 10 hereof or because of any refusal, inability or failure on the part of
the Company to perform any agreement


<PAGE>


                                                                              27

herein or comply with any provision hereof other than by reason of a default by
any of the Underwriters, the Company will reimburse the Underwriters severally
upon demand for all out-of-pocket expenses (including reasonable fees and
disbursements of counsel) that shall have been incurred by them in connection
with the proposed purchase and sale of the Securities.

     12. The respective agreements, representations, warranties, indemnities and
other statements of the Company, the Issuer and the several Underwriters set
forth in this Agreement or made by or on behalf of them, respectively, pursuant
to this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter or the Company
or any officer, director or controlling person of the Company, and shall survive

     2.01. Name. The Trust continued hereby shall be known as "PECO Energy
Transition Trust," in which name the Trustees shall conduct the business of the
Trust, make and execute contracts, and sue and be sued.


                                        4

     2.02. Office. The initial office of the Trust shall be in care of the
Issuer Trustee, One Rodney Square, 920 King Street, 1st Floor, Wilmington,
Delaware 19801 (telephone number 302-888-7532) or at such other address as the
Trustees may designate by notice to the Grantor, any Owner and the Bond Trustee,
provided that any other office will comply with the provisions of 4.01(c) and
(e).

     2.03. Purposes and Powers; Intent. (a) The Trust has been created for the
purpose of purchasing and owning Intangible Transition Property, issuing
Transition Bonds from time to time, pledging its interest in Intangible
Transition Property and other Collateral to the Bond Trustee under the Indenture
in order to secure the Transition Bonds and performing activities that are
necessary, suitable or convenient to accomplish these purposes, including, but
not limited to, entering into any hedge or swap arrangement with respect to the
Transition Bonds.

           (b) The Grantor has determined that each of (i) the creation and
ownership of the Trust by the Grantor and (ii) the limited purposes of the Trust
is in the best interests of the Grantor and its creditors and represents a
prudent and advisable course of action that does not impair the rights and
interests of the Grantor's creditors. The Grantor has determined that the
transactions contemplated by this Agreement and the Trust Related Agreements are
in the best interests of the Grantor and its creditors and represent a prudent
and advisable course of action that does not impair the rights and interests of
the Grantor's creditors. Such determinations are memorialized in the corporate
records of the Grantor. The Grantor did not create the Trust with the intent to
hinder, delay, or defraud the Grantor's creditors, and any transfer to the Trust
will not render the Grantor insolvent or incapable of conducting its business in
the manner and to the extent presently conducted.

           (c) The Trust shall not have the power to (i) incur any debt other
than the Transition Bonds and certain costs and expenses associated therewith
(including day-to-day expenses incurred by the Trust) and debt in connection
with any credit enhancement required for any Series of Transition Bonds or (ii)
engage in any business or activity other than the business and activities
enumerated in Section 2.03 (other than in accordance with Section 6.02(a)).

           (d) The Trust's existence is not dependent on its being a subsidiary
of the Grantor or being affiliated with any Affiliated Entity, and the Trust's
business operations could be maintained even if it were not a subsidiary of the
Grantor or affiliated with any other Affiliated Entity. The Grantor will not
transfer additional Intangible Transition Property to the Trust for the purpose
of mitigating losses on the Intangible Transition Property that has previously
been transferred to the Trust.

           (e) The Trust has determined that the transactions contemplated by
the Trust Related Agreements are in the best interests of the Trust and its
creditors and represent a prudent and advisable course of action that does not
impair the rights and interests of the Trust's creditors.

     2.04. Appointment of the Trustees; Initial Trust Property. (a) The Trust
shall have no fewer than one and no more than three trustees (if the Delaware
Trustee, Issuer Trustee and Independent Trustee are the same entity) or five
trustees (if the Delaware Trustee, Issuer Trustee and Independent Trustee are
different entities) appointed from time to time by the Grantor or, in the event
of a Transfer, by the Owner or Owners. The Grantor or, in the event of a
Transfer, the Owners may at any time increase the number of Trustees, subject to
the provisions of Sections 2.04(b), 3.01, 4.01 and 4.03. The


                                        5

<PAGE>


Grantor has appointed First Union Trust Company, National Association as Issuer
Trustee, Delaware Trustee and Independent Trustee, and George Shicora and Thomas
R. Miller as Beneficiary Trustees of the Trust, which Trustees shall have all
the rights, powers and duties set forth herein.

           (b) The Trust shall at all times have an Issuer Trustee which shall
be a Person meeting the qualifications of Section 11.01(c) of this Agreement. In
addition, the Trust shall at all times have at least one Trustee which qualifies
as a Delaware Trustee and at least one Trustee which qualifies as an Independent
Trustee. The Issuer Trustee, the Delaware Trustee and the Independent Trustee
may, and will initially, be the same entity.

           (c) The Trustees acknowledge receipt in trust from the Grantor, as of
June 23, 1998, of the sum of $5,000, constituting the initial Trust Property.

     2.05. Declaration of Trust. The Trustees hereby declare that they will hold
the Trust Property in trust upon and subject to the conditions set forth herein
for the use and benefit of the Grantor or, in the event of a Transfer, any
Owner, subject to the obligations of the Trust under the Trust Related
Agreements. It is the intention of the parties hereto that the Trust constitutes
a business trust under the Business Trust Act and that this Agreement
constitutes the governing instrument of the Trust. On June 23, 1998, the
Trustees filed a Certificate of Trust with the Delaware Secretary of State in
accordance with the provisions of the Business Trust Act in substantially the
form attached hereto as Exhibit 2.

     2.06. Other Expenses, Liabilities of Trust. None of the Grantor, the
Trustees or any Owner shall be liable for any liabilities or obligations of the
Trust, including but not limited to, the indemnification obligations under
Article IX.

     2.07. Situs of Trust. The Trust will be located and administered in the
State of Delaware. All bank accounts maintained by the Trustees on behalf of the
Trust shall be located in the State of Delaware. The Trust shall not have any
employees in any state other than in the State of Delaware; provided, however,
that nothing shall restrict or prohibit the Issuer Trustee from having employees
within or without the State of Delaware. Payments will be received by the Trust
only in the State of Delaware and payments will be made by the Trust only from
the State of Delaware.

     2.08. Additional Capital Contributions. The assets of the Trust are
expected to generate a return sufficient to satisfy all obligations of the Trust
under this Agreement and the Trust Related Agreements and any other obligations
of the Trust. It is expected that no capital contributions to the Trust will be
necessary after the purchase of the initial Intangible Transitional Property,
except for capital contributions in connection with the issuance of additional
Series of Transition Bonds. In accordance with the private letter ruling
received by the Grantor from the Internal Revenue Service dated December 19,
1997 (the "Private Letter Ruling"), on or prior to the date of issuance of each
Series of Transition Bonds, the Grantor or, in the event of a Transfer, any
Owner, shall make an additional contribution to the Trust in an amount equal to
at least 0.50% of the initial principal amount of such Series or such greater
amount as agreed to by the Grantor in connection with the issuance by the Trust
of any Series of Transition Bonds. No capital contribution by the Grantor or any
Owner, as the case may be, to the Trust has been or will be made for the purpose
of mitigating losses on Transition Property that has previously been transferred
to the Trust, and all capital contributions shall be made in accordance with all
applicable corporate business trust procedures and


                                        6

<PAGE>


requirements, including proper record keeping by the Grantor and the Trust. Each
capital contribution will be acknowledged by a written receipt signed by any of
the Trustees. The Trustees acknowledge and agree that, notwithstanding anything
in this Agreement to the contrary, such additional contribution will be managed
by an investment manager selected by the Grantor or, in the event of a Transfer,
the Owner or Owners who shall invest such amounts only in Eligible Investments
(as defined in the Indenture), and all income earned thereon shall be allocated
or paid by the Bond Trustee in accordance with the provisions of the Indenture.

     2.09. Assignment of Right to Distributions or Payments; Transfers. The
Grantor and any Owner may assign all or any part of their respective rights to
receive distributions or payments hereunder, but such assignment shall effect no
change in the ownership of the Trust. No Transfer of a beneficial interest in
the Trust shall be made by the Grantor, except to an Affiliate or in connection
with the sale or disposition of all or substantially all of the Grantor's
electric generating business, whether by operation of law or otherwise, and only
if prior notice of such assignment is provided to Moody's.

                                   ARTICLE III

                            COMPLIANCE WITH THE CODE

     3.01. Trust to be Treated as a Division For Tax Purposes. The Trust shall
comply with the applicable provisions of the Code and the applicable Treasury
regulations thereunder in the manner necessary to effect the intention of the
parties that the Trust be treated as a division of PECO Energy for federal
income tax purposes pursuant to Treasury regulation ss. 301.7701-1 et seq. and
that the Trust be accorded such treatment until its termination pursuant to
Section 10.01 hereof and shall take, or refrain from taking, any action required
by the Code or Treasury regulations thereunder in order to maintain such status
of the Trust. In addition, the Trust may not claim any credit on, or make any
deduction from the principal and interest payable in respect of, the Transition
Bonds (other than amounts properly withheld under the Code), or assert any claim
against any present or former Transition Bondholder because of the payment of
taxes levied or assessed upon the Trust.

                                   ARTICLE IV

                           SEPARATE EXISTENCE OF TRUST

     4.01. Maintenance of Separate Existence. The Trust shall take all steps
necessary to continue the identity of the Trust as a separate legal entity and
to make it apparent to third Persons that the Trust is an entity with assets and
liabilities distinct from those of the Grantor, any Owner, the Trustees,
Affiliates of the Grantor or any Owner or any other Person, and that, except for
financial reporting purposes (to the extent required by generally accepted
accounting principles) and for state and federal income and franchise tax
purposes, it is not a division of any of the Affiliated Entities or any other
Person. In that regard, and without limiting the foregoing in any manner, the
Trust shall:

based upon the creditworthiness or assets of any Affiliated Entity or any other
Person (i.e. other than based on the assets of the Trust) nor allow any

                                        8

expenses of the Trust and shall be permitted to pay certain of the expenses

           (z) treat and cause the Grantor to treat the transfer of Intangible

none of the Intangible Transition Property, any qualified rate orders or PECO
Energy's or the Trust's rights under the Competition Act or any qualified rate

Related Agreements, the Issuer is solvent and expects to remain solvent,

Services that such event will not result in either a downgrade or withdrawal of
the then current rating of the Transition Bonds.

     5.01. Investment of Trust Funds. The provisions of this Article V apply
only to funds or Trust Property that have been released from the lien of the
Indenture and are permitted to be held or applied by the Trust. Unless otherwise

Trust shall be invested and reinvested by the Trustees (or by an independent
investment manager appointed in writing by the Beneficiary Trustees) in Eligible
Investments.

                      AUTHORITY AND DUTIES OF THE TRUSTEES

     6.01. General Authority. The Trustees are authorized to take all actions
required to be taken by them pursuant to the terms of this Agreement and the
Trust Related Agreements. The Trustees are further authorized, but shall not be
obligated, to take such further actions as are permitted but not required under
the terms of this Agreement and the Trust Related Agreements.


                                       12

     6.02. Specific Authority; Special Authority of Beneficiary Trustees. (a)
Notwithstanding any other provision in this Agreement to the contrary and
without the need for any additional consent of any Person, the Trustees, acting
singly or collectively, are hereby authorized and directed to take the following
action on behalf of the Trust: (i) execute, deliver and perform any agreements
related to the issuance and sale of Transition Bonds, including the Trust
Related Agreements, as necessary, (ii) execute and deliver all certificates and
other documents required by any such agreements and (iii) issue and deliver one
or more series of Transition Bonds in accordance with the provisions of such
agreements and any qualified rate orders and qualify and register the Transition
Bonds for sale in various states. The Trustees, acting singly or collectively,
are authorized to take all actions necessary or incidental to the day-to-day
operations of the Trust. Except as otherwise specifically provided, all
non-day-to-day matters shall be determined by a majority of the then current
Trustees; provided that, such majority must include the Independent Trustee
(which may also be the Issuer Trustee) for all actions specified in Sections
4.02 and 4.03 and any matter that would, if approved by the Trustees, cause the
Trust to deviate from the provisions of Sections 2.03(a), 2.03(c), 2.04(b), 4.01
and 12.01 of this Agreement (or any provisions that by the terms hereof require
the consent of the Independent Trustee), subject to the provisions of Section
6.05. For purposes of determining a majority under this Agreement, each Person
that is serving as a Trustee shall be counted as a single Trustee, even if such
Person holds multiple Trustee positions (i.e., the vote of one Person that acts
as Delaware Trustee, Issuer Trustee and Independent Trustee shall be counted
only once).

           (b) The Grantor and the Trustees hereby authorize and direct the
Beneficiary Trustees, acting singly or collectively, (i) to file with the
Securities and Exchange Commission (the "Commission") and execute, in each case
on behalf of the Trust, one or more Registration Statements on either Form S-3
or Form S-1 (collectively, the "1933 Act Registration Statements"), including
any pre-effective or post-effective amendments to such 1933 Act Registration
Statements (including the prospectus supplement, the prospectus and the exhibits
contained therein), relating to the registration under the Securities Act of
1933, as amended, of each Series of Transition Bonds, (ii) to file and execute
on behalf of the Trust such applications, reports, surety bonds, irrevocable
consents, appointments of attorney for service of process and other papers and
documents as shall be necessary or desirable to register each Series of
Transition Bonds under the securities or "Blue Sky" laws of such jurisdictions
as the Trust may deem necessary or desirable and (iii) to do or cause to be done
all such other acts or things and to execute and deliver all such instruments
and documents that any such Beneficiary Trustee shall deem necessary or
appropriate to carry out the intent of the foregoing. In the event that any
filing referred to above is required by the rules and regulations of the
Commission or state securities or "Blue Sky" laws, to be executed on behalf of
the Trust by the Issuer Trustee, then the Issuer Trustee, not in its individual
capacity, but solely in its capacity as trustee of the Trust, is hereby
authorized and directed to join in any such filing and to execute on behalf of
the Trust any and all of the foregoing. In connection with all of the foregoing,
the Trust hereby constitutes and appoints each of the Beneficiary Trustees as
its true and lawful attorney-in-fact and agent, with full power of substitution
and resubstitution, for the Trust or in the Trust's name, place and stead, in
any and all capacities, to sign any and all amendments (including post-effective
amendments) to the 1933 Act Registration Statements and to file the same, with
all exhibits thereto, and other documents in connection therewith, with the
Commission, granting unto said attorney-in-fact and agent full power and
authority to do and perform each and every act and thing requisite and necessary
to be done in connection therewith, as fully to all intents and purposes as the
Trust might or could do in person, hereby ratifying and confirming all that said
attorney-in-fact and agent, or his respective substitute or substitutes, shall
do or cause to be done by virtue hereof.

           (c) Meetings of the Trustees for the purpose of establishing a
majority under this Article VI or otherwise may be called at any time by any of
the Trustees upon two days written or oral notice, stating the time, place and
purpose of the meeting, to all Trustees prior to the time of the meeting. In
addition, any action required or permitted to be taken at a meeting of the
Trustees may be taken without a meeting upon the written consent of the Trustees
who would be necessary to authorize the action at a meeting at which all
Trustees were present and voting or upon the unanimous written consent of the
Trustees. The Issuer Trustee shall maintain the minutes of all meetings of the
Trustees. Any meeting may be held by means of conference telephone or similar
communications equipment by which all persons participating in the meeting can
hear one another. Attendance, whether by telephone or in person, at any meeting
of the Trustees shall constitute a waiver of notice of such meeting.

     6.03. Accounting and Reports to the Grantor, any Owner, the Internal
Revenue Service and Others. The Grantor shall designate, from time to time, a
Trustee which shall, on behalf of the Trust, (i) maintain or cause to be
maintained the books of the Trust on a calendar year basis on the accrual method
of accounting, (ii) deliver to the Grantor and any Owner, within 90 days of the
end of each Fiscal Year, or more often, as may be required by the Code and the
regulations thereunder, a copy of the annual financial statement of the Trust
for such Fiscal Year and a statement in such form and containing such
information as may be required by such regulations, and as is necessary and
appropriate to enable the Grantor and any Owner to prepare its federal and state
income tax returns, (iii) file such tax returns relating to the Trust, cause the
Trust to pay all taxes incurred by it pursuant to the terms of any tax sharing
agreement entered into by the Trust and the Grantor and take all actions
necessary for the Trust to qualify or continue to qualify as a division of PECO
Energy or its designated affiliate for federal income tax purposes, (iv) cause
such tax returns to be signed by the Trust in the manner required by law, and
(v) cause to be mailed to the Grantor and any Owner copies of all such reports
and tax returns of the Trust.

     6.04. Signature of Returns. The Trustee designated in Section 6.03 shall
sign on behalf of the Trust the tax returns and other periodic filings of the
Trust, unless applicable law requires the Owner to sign such documents, in which
case, so long as the Grantor is the Owner and applicable law allows the Grantor
to sign any such document, the Grantor shall sign such document. At any time
that the Grantor is not the Owner, or is otherwise not allowed by law to sign
any such document, then the party required by law to sign such document shall
sign.

     6.05. Right to Receive Instructions. In the event that the Trustees are
unable to decide between alternative courses of action for whatever reason, or
are unsure as to the application of any provision of this Agreement or any Trust
Related Agreement, or such provision is ambiguous as to its application, or is,
or appears to be, in conflict with any other applicable provision, or in the
event that this Agreement or any Trust Related Agreement permits any
determination by the Trustees or is silent or is incomplete as to the course of
action which the Trustees are required to take with respect to a particular set
of facts, any one or more of the Trustees may give notice of such circumstances
(in such form as shall be appropriate under the circumstances) to the Grantor
or, in the event of a Transfer, to the Owner and request instructions from
independent, appropriate legal or other counsel to the Trustees in accordance
with Section 7.03 of this Agreement.

     6.06. No Duties Except as Specified in this Agreement or in Instructions.
The Trustees shall not have any duty or obligation to manage, make any payment
in respect


                                       14

<PAGE>


of, register, record, sell, dispose of or otherwise deal with the Trust
Property, or to otherwise take or refrain from taking any action under, or in
connection with, any document contemplated hereby to which the Trustees are a
party, except as expressly provided by the terms of this Agreement or the Trust
Related Agreements and no implied duties or obligations shall be read into this
Agreement or the Trust Related Agreements against the Trustees. The Trustees
nevertheless agree that, in the event that claims are made against any of the
Trustees in their individual capacities that are not related to the ownership or
the administration of the Trust Property or the transactions contemplated by the
Trust Related Agreements, the Trustee against whom such claims were made shall,
at its own cost and expense, promptly take all action as may be necessary to
discharge any liens on any part of the Trust Property resulting from those
claims.

     6.07. No Action Except Under Specified Documents or Instructions. The
Trustees shall not manage, control, use, sell, dispose of or otherwise deal with
any part of the Trust Property except in accordance with the powers granted to
and the authority conferred upon the Trustees pursuant to this Agreement and the
Trust Related Agreements.

     6.08 No Action Contrary to Agreement, Trust Related Agreements or
Applicable Law. The Trustees shall not be required to take or refrain from
taking any action under this Agreement or the Trust Related Agreements if the
Trustees shall reasonably determine or shall have been advised by counsel that
such action (i) is contrary to the terms of this Agreement or the Trust Related
Agreements or is otherwise contrary to applicable law or (ii) is likely to
result in liability on the part of the Trustees to risk or advance their own
funds.

                                   ARTICLE VII

                             CONCERNING THE TRUSTEES

     7.01. Acceptance of Trusts and Duties. The Trustees accept the trusts
hereby created and agree to perform their respective duties hereunder with
respect to the same but only upon the terms of this Agreement. The Trustees
shall not be personally liable under any circumstances except (i) for their own
willful misconduct or gross negligence, (ii) for liabilities arising from the
failure by any of the Trustees to perform obligations expressly undertaken by
them in Article VI, or (iii) for taxes, fees or other charges on, based on or
measured by any fees, commissions or compensation received by the Trustees in
connection with any of the transactions contemplated by this Agreement or the

expend or risk their personal funds or otherwise incur any financial Liability
in the performance of any of their rights or


                                       15

<PAGE>


powers hereunder, if the Trustees shall have reasonable grounds for believing
that repayment of such funds or adequate indemnity against such risk or
Liability is not reasonably assured or provided to them;

           (d) Under no circumstance shall the Trustees be personally liable for
any indebtedness of the Trust under any Trust Related Agreement; and

           (e) The Trustees shall not be personally responsible for or in
respect of the validity or sufficiency of this Agreement or for the due
execution hereof by the Grantor, or for the form, character, genuineness,
sufficiency, value or validity of any Collateral, or for or in respect of the
validity or sufficiency of the Trust Related Agreements.

     7.02. Furnishing of Documents. The Trustees shall furnish to the Grantor
and any Owner, promptly upon receipt thereof, duplicates or copies of all
material reports, notices, requests, demands, certificates, financial statements
and any other instruments furnished to the Trustees by any party pursuant to the
Trust Related Agreements (other than documents originated by or otherwise
furnished by the Grantor or any Owner).

     7.03. Reliance; Advice of Counsel. (a) The Trustees shall incur no
Liability to anyone in acting upon any signature, instrument, notice,
resolution, request, consent, order, certificate, report, opinion, bond or other
document or paper believed by them to be genuine and believed by them to be
signed by the proper party or parties. The Trustees may accept a certified copy
of a resolution of the board of directors or other governing body of any
corporate party as conclusive evidence that such resolution has been duly
adopted by such body and that the same is in full force and effect. As to any
fact or matter the manner of ascertainment of which is not specifically
prescribed herein, the Trustees may for all purposes hereof rely on a
certificate, signed by the president or any vice president or by the treasurer
or any assistant treasurer or the secretary or any assistant secretary of the
relevant party, as to such fact or matter, and such certificate shall constitute
full protection to the Trustees for any action taken or omitted to be taken by
them in good faith in reliance thereon.

           (b) In the exercise or administration of the trusts hereunder and in
the performance of their respective duties and obligations under any of the
Trust Related Agreements, the Trustees (i) may act directly or, at the expense
of the Trust in the case of the Issuer Trustee, through agents or attorneys
pursuant to agreements entered into with any of them, and the Trustees shall not
be liable for the default or misconduct of such agents or attorneys if such
agents or attorneys shall have been selected by the Trustees with reasonable
care and (ii) may, at the expense of the Trust in the case of the Issuer
Trustee, consult with counsel, accountants and other skilled persons to be
selected with reasonable care and employed by them, and the Trustees shall not
be liable for anything done, suffered or omitted in good faith by it in
accordance with the advice or opinion of any such counsel, accountants or other
skilled persons.

     7.04. Not Acting in Individual Capacity. Except as expressly provided in
this Article VII, in accepting the trusts hereby created the Trustees each act
solely as trustees hereunder and not in their respective individual capacities,
and all Persons having any claim against the Trustees by reason of the
transactions contemplated by this Agreement or the Trust Related Agreements
shall look only to the Trust Property for payment or satisfaction thereof.

Trust shall indemnify the Trustees and their agents, employees and directors
against any Liability incurred in connection with any Proceeding in which the
Trustees may be involved as a party or otherwise by reason of the fact that such
Trustee is or was serving in its capacity as a Trustee, unless such Liability is
based on or arises in connection with the Trustee's or such other indemnified
parties' own wilful misconduct or gross negligence, the failure to perform the
obligations expressly undertaken by them in Article VI, or taxes, fees or other

but in no event before payment in full of all Series of Transition Bonds.

            (b) The bankruptcy of either the Grantor or any Owner or both shall
not operate to terminate this Agreement, to dissolve, terminate or annul the

accounting or to take any action or Proceeding in any court for a partition or
winding up of the Trust Property, nor otherwise affect the rights, obligations
and liabilities of the parties hereto.

     11.01. Resignation of Trustee; Appointment of Successor. (a) The Trustees
may resign at any time without cause by giving at least 90 days' prior written
notice to the Grantor and any Owner, such resignation to be effective upon the

addition, the Grantor or, in the event of a Transfer, any Owner may at any time
remove any of the Trustees with or without cause by an instrument in writing
delivered to the Trustee, such removal to be effective upon the acceptance of
appointment by a successor Trustee under Section 11.01(b); except that, neither
the Grantor nor any Owner may remove the Independent Trustee (i) without cause,
(ii) after an Event of Default under the Indenture or (iii) if the removal of
one or more Trustees would cause the breach of Section 2.04(b). In case of the
resignation or removal of a Trustee, the Grantor or, in the event of a Transfer,
any Owner may appoint a successor Trustee by an instrument signed by the Grantor
or any Owner, as applicable, subject to Section 2.04(b). If the last remaining
Trustee of the Trust resigns or is removed or the Issuer Trustee, the
Independent Trustee or the Delaware Trustee resigns or is removed and a
successor Trustee shall not have been appointed within 30 days after the giving
of written notice of such resignation or the delivery of the written instrument
with respect to such removal, such Trustee, the Grantor or any Owner


                                       18

<PAGE>


may apply to any court of competent jurisdiction to appoint a successor Trustee
in compliance with Section 2.04(b) to act until such time, if any, as a
successor Trustee shall have been appointed as provided above. Any successor
Trustee so appointed by such court shall immediately and without further act be
superseded by any successor Trustee appointed as above provided. In the event of
removal of a Trustee, the Trustee so removed shall be entitled to compensation
and reimbursement for expenses incurred through the date of such removal.

            (b) Any successor Trustee, however appointed, shall execute and
deliver to the predecessor Trustee and the Trust an instrument accepting such
appointment, and thereupon such successor Trustee, without further acts, shall
become vested with all the estates, properties, rights, powers, duties and
trusts of the predecessor Trustee in the trusts hereunder with like effect as if
originally named as a Trustee herein; but nevertheless, upon the written request
of such successor Trustee, such predecessor Trustee shall execute and deliver an
instrument transferring to such successor Trustee, upon the trusts herein

giving rise to such Schedule Revision Date and setting forth the Expected
Amortization Schedule for each Payment Date and the Monthly Allocated Interest

                          [REVERSE OF TRANSITION BOND]


     This Series 2000-A, Class [ ] Transition Bond is one of a duly authorized
issue of Transition Bonds of the Issuer, designated as its Transition Bonds
(herein called the "Transition Bonds"), issued and to be issued in one or more
Series, which Series are issuable in one or more Classes, and this Series 2000-A
Transition Bond, in which this Class [ ] Transition Bond represents an interest,
consists of four Classes, including the Class [ ] Transition Bonds (herein
called the "Class [ ] Transition Bonds"), all issued and to be issued under an
indenture dated as of March 1, 1999, and a series supplement thereto dated as of
May 2, 2000 (such series supplement, as supplemented or amended, the
"Supplement" and, collectively with such indenture, as supplemented or amended,
the "Indenture"), each between the Issuer and The Bank of New York, as Bond
Trustee (the "Bond Trustee", which term includes any successor bond trustee
under the Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the Collateral property pledged, the
nature and extent of the security, the respective rights, obligations and
immunities thereunder of the Issuer, the Bond Trustee and the Holders of the
Transition Bonds and the terms and conditions under which additional Transition
Bonds may be issued. All terms used in this Class [ ] Transition Bond that are
defined in the Indenture, as supplemented or amended, shall have the meanings
assigned to them in the Indenture.

     The Class [ ] Transition Bonds, the other Classes of Series 2000-A
Transition Bonds and any other Series of Transition Bonds issued by the Issuer
are and will be equally and ratably secured by the Collateral pledged as
security therefor as provided in the Indenture.

     The principal of this Class [ ] Transition Bond shall be payable on each
Payment Date only to the extent that amounts in the Collection Account are
available therefor, and only until the outstanding principal balance thereof on
such Payment Date (after giving effect to all payments of principal, if any,
made on such Payment Date) has been reduced to the principal balance specified
in the Expected Amortization Schedule which is attached to the Supplement as
Schedule A, unless payable earlier either because (i) an Event of Default shall
have occurred and be continuing and the Bond Trustee or the Holders of
Transition

                                                                               6

Bonds representing not less than a majority of the Outstanding Amount of the
Transition Bonds of all Series have declared the Transition Bonds to be
immediately due and payable in accordance with Section 5.02 of the Indenture,
(ii) the Issuer, at its option, shall have called for the redemption of the
Series 2000-A Transition Bonds in whole or from time to time in part pursuant to
Section 10.01 of the Indenture, (iii) the Issuer shall have called for the
redemption of the Series 2000-A Transition Bonds pursuant to Section 10.02 of
the Indenture if the Seller is required to pay Liquidated Damages pursuant to
Section 5.01(d) of the Sale Agreement or (iv) the Issuer, at its option, shall
have called for the redemption of the Series 2000-A Transition Bonds in whole
pursuant to Section 6(b) of the Supplement. However, actual principal payments
may be made in lesser than expected amounts and at later than expected times as
determined pursuant to Section 8.02(e) of the Indenture. The entire unpaid
principal amount of this Class [ ] Transition Bond shall be due and payable on
the earlier of the Class [ ] Termination Date hereof and the Redemption Date, if
any, herefor. Notwithstanding the foregoing, the entire unpaid principal amount
of the Transition Bonds shall be due and payable, if not then previously paid,
on the date on which an Event of Default shall have occurred and be continuing
and the Bond Trustee or the Holders of the Transition Bonds representing not
less than a majority of the Outstanding Amount of the Transition Bonds have
declared the Transition Bonds to be immediately due and payable in the manner
provided in Section 5.02 of the Indenture. All principal payments on the Class
[ ] Transition Bonds shall be made pro rata to the Class [ ] Transition
Bondholders entitled thereto based on the respective principal amounts of the
Class [ ] Transition Bonds held by them.

     Payments of interest on this Class [ ] Transition Bond due and payable on
each Payment Date, together with the instalment of principal or premium, if any,
due on this Class [ ] Transition Bond on such Payment Date shall be made by
check mailed first-class, postage prepaid, to the Person whose name appears as
the Registered Holder of this Class [ ] Transition Bond (or one or more
Predecessor Transition Bonds) in the Transition Bond Register as of the close of
business on the Record Date or in such other manner as may be provided in the
Supplement, except that with respect to Class [ ] Transition Bonds registered on
the Record Date in the name of a Clearing Agency, payments will be made by wire
transfer in immediately available funds to the account designated by such
Clearing Agency and except

to this Class [ ] Transition Bond on a Payment Date which shall be payable as
provided below. Such checks shall be mailed to the Person entitled thereto at
the address of such Person as it appears in the Transition Bond Register as of
the applicable Record Date without requiring that this Class [ ] Transition Bond
be submitted for notation of payment. Any reduction in the principal amount of
this Class [ ] Transition Bond (or any one or more Predecessor Transition Bonds)
effected by any payments made on any Payment Date shall be binding upon all
future Holders of this Class [ ] Transition Bond and of any Class [ ] Transition
Bond issued upon the registration of transfer hereof or in exchange hereof or in
lieu hereof, whether or not noted hereon. If funds are expected to be available,
as provided in the Indenture, for payment in full of the then remaining unpaid
principal amount of this Class [ ] Transition Bond on a Payment Date, then the
Bond Trustee, in the name of and on behalf of the Issuer, will notify the Person
who was the Registered Holder hereof as of the second preceding Record Date to
such Payment Date by notice mailed no later than five days prior to such final
Payment Date and shall specify that such final instalment will be payable to the
Registered Holder hereof as of the Record Date immediately preceding such final
Payment Date and only upon presentation and surrender of this Class [ ]
Transition Bond and shall specify the place where this Class [ ] Transition Bond
may be presented and surrendered for payment of such instalment.

     The Issuer shall pay interest on overdue instalments of interest on this
Class [ ] Transition Bond at the Class [ ] Bond Rate to the extent lawful.

     As provided in the Indenture, the Class [ ] Transition Bonds may be
redeemed, in whole or from time to time in part, at the option of the Issuer on
any Redemption Date at the Redemption Price. In addition, as provided in the
Indenture, if the Seller is required to pay Liquidated Damages pursuant to
Section 5.01(d) of the Sale Agreement, the Issuer will be required to redeem all
outstanding Series of Transition Bonds, including the Class [ ] Transition
Bonds, on the Liquidated Damages Redemption Date.

     As provided in the Indenture and subject to certain limitations set forth
therein, the transfer of this Class [ ] Transition Bond may be registered in the
Transition Bond Register upon surrender of this Class [ ]

                                                                               8

such signature guaranteed by an Eligible Guarantor Institution, and thereupon
one or more new Class [ ] Transition Bonds of any Authorized Initial
Denominations and in the same aggregate initial principal amount will be issued
to the designated transferee or transferees. No service charge will be charged
for any registration of transfer or exchange of this Class [ ] Transition Bond,
but the transferor may be required to pay a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any
registration of transfer or exchange.

     Each Class [ ] Transition Bondholder, by acceptance of a Class [ ]
Transition Bond, covenants and agrees that no recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer or the Bond Trustee on
the Class [ ] Transition Bonds or under the Indenture or any certificate or
other writing delivered in connection herewith or therewith, against (i) any
owner of a beneficial interest in the Issuer or (ii) any partner, owner,
beneficiary, agent, officer, director or employee of the Bond Trustee, any
holder of a beneficial interest in the Issuer or the Bond Trustee or of any
successor or assign of the Bond Trustee, except as any such Person may have
expressly agreed (it being understood that all of the Bond Trustee's obligations
are in its individual capacity).

     Prior to the due presentment for registration of transfer of this Class [ ]
Transition Bond, the Issuer, the Bond Trustee and any agent of the Issuer or the
Bond Trustee may treat the Person in whose name this Class [ ] Transition Bond
is registered (as of the day of determination) as the owner hereof for the
purpose of receiving payments of principal of and premium, if any, and interest
on this Class [ ] Transition Bond and for all other purposes whatsoever, whether

Transition Bonds under the Indenture at any time by the Issuer with the consent

Transition Bonds representing specified percentages of the Outstanding Amount of
the Transition Bonds of all Series, on behalf of the Holders of all the
Transition Bonds, to waive compliance by the Issuer with certain provisions of
the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Class [ ]
Transition Bond (or any one of more Predecessor Transition Bonds) shall be
conclusive and binding upon such Holder and upon all future Holders of this
Class [ ] Transition Bond and of any Class [ ] Transition Bond issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof whether
or not notation of such consent or waiver is made upon this Class [ ] Transition
Bond. The Indenture also permits the Bond Trustee to amend or waive certain
terms and conditions set forth in the Indenture without the consent of Holders
of the Transition Bonds issued thereunder.

     The term "Issuer" as used in this Class [ ] Transition Bond includes any
successor to the Issuer under the Indenture.

     The Issuer is permitted by the Indenture, under certain circumstances, to
merge or consolidate, subject to the rights of the Bond Trustee and the Holders
of Transition Bonds under the Indenture.

     The Class [ ] Transition Bonds are issuable only in registered form in
Authorized Initial Denominations as provided in the Indenture and the
Supplement, subject to certain limitations therein set forth.

and remedies of the parties hereunder and thereunder shall be determined in

powers and appropriate to further a legitimate public purpose, and, under the
Takings Clauses of the Pennsylvania and United States Constitutions, in the
event such action constitutes a permanent appropriation of the property interest
of Transition Bondholders in the Intangible Transition Property and deprives the
Transition Bondholders of their reasonable expectations arising from their
investments in Transition Bonds, unless just compensation, as determined by a
court of competent jurisdiction, is provided to Transition Bondholders. (iv)
There is no order by any court providing for the revocation, alteration,
limitation or other impairment of the Statute, any Qualified Rate Order, the
Intangible Transition Property or the Intangible Transition Charges or any
rights arising under any of them or which seeks to enjoin the performance of any
obligations under the Qualified Rate Orders. (v) No other approval,
authorization, consent, order or other action of, or filing with, any court,
Federal or state regulatory body, administrative agency or other governmental
instrumentality is required in connection with the creation of the Intangible
Transition Property, except those that have been obtained or made. (vi) Except
as disclosed by the Seller to

the Issuer there are no proceedings or investigations pending, or to the
Seller's best knowledge, threatened before any court, Federal or state
regulatory body, administrative agency or other governmental instrumentality
having jurisdiction over the Seller or its properties challenging any Qualified
Rate Order or the Statute. (vii) No failure on the Initial Transfer Date or any
Subsequent Transfer Date or any time thereafter to satisfy any condition imposed
by the Statute with respect to the recovery of stranded costs will adversely
affect the creation or sale hereunder of Intangible Transition Property or the
right to collect Intangible Transition Charges.

     (e) Assumptions. The assumptions used in calculating Intangible Transition
Charges are reasonable and made in good faith.

     (f) Creation of Intangible Transition Property. (i) The Intangible

constitutes a current property right, (ii) the Intangible Transition Property
includes, without limitation, (A) the irrevocable right of the Issuer and any
Other Issuers to receive through Intangible Transition Charges an amount
sufficient to recover all of the Seller's Qualified Transition Expenses
described in the Qualified Rate Orders in an amount equal to the aggregate
principal amount of Transition Bonds and Other

Transition Bonds plus an amount sufficient to provide for any credit enhancement
(including the Overcollateralization Amount relating to each Series of
Transition Bonds), to fund any reserves, and to pay interest, premium, if any,
servicing fees and other expenses relating to the Transition Bonds and Other
Transition Bonds, and (B) all right, title and interest of the Seller or its
assignee applicable to the Transition Bonds and Other Transition Bonds in the
Qualified Rate Orders and in all revenues, collections, claims, payments, money
or proceeds of or arising from the Intangible Transition Charges applicable to
the Transition Bonds and Other Transition Bonds set forth in the Qualified Rate
Orders to the extent that in accordance with the Statute, the Qualified Rate
Orders and the rates and charges authorized under the Qualified Rate Orders are
declared to be irrevocable and (iii) paragraphs four through nineteen of the
Initial Qualified Rate Order and paragraphs four through eighteen of the Second
Qualified Rate Order (and the comparable paragraphs for any subsequent Qualified
Rate Order), including the right to collect Intangible Transition Charges, have
been declared to be irrevocable by the PUC.

Transition Property hereunder, the Seller (i) is solvent and expects to remain
solvent, (ii) is adequately capitalized to conduct its business and


<PAGE>


                                                                              25

affairs considering its size and the nature of its business and intended
purposes, (iii) is not engaged in nor does it expect to engage in a business for
which its remaining property represents an unreasonably small capital, (iv)
believes that it will be able to pay its debts as they come due and that such
belief is reasonable and (v) is able to pay its debts as they mature and does
not intend to incur, or believe that it will incur, indebtedness that it will

     (h) Swap Payments. Semiannual fixed amounts payable by the Issuer to a
Counterparty in respect of fixed interest under a Swap Agreement are includable
in Intangible Transition Charges.

of the Transition Bonds are outstanding, the Seller will keep in full force and
effect its corporate existence and remain in good standing, in each case under

its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and

                                                                              26

Agency Condition is satisfied with respect to all outstanding Transition Bonds
and (ii) each such Other Issuer is, or prior to such sale becomes, a party to
the Master Servicing Agreement as an "Issuer" (as defined in the Master
Servicing Agreement). The Seller shall not at any time assert any Lien against

the right, title and interest of the Issuer, the Bond Trustee, as assignee of
the Issuer, and any Other Issuers in, to and under the Intangible Transition
Property, whether now existing or hereafter created, against all claims of third
parties claiming through or under the Seller.

its organizational or governing documents and all laws, treaties, rules,
regulations and determinations of any governmental instrumentality applicable to

Intangible Transition Property or under any of the Basic Documents or the
Seller's performance of its obligations hereunder or under any of the other
Basic Documents to which it is a party.

     SECTION 4.06. Covenants Related to Intangible Transition Property. (a) So
long as any of the Transition Bonds are outstanding, the Seller shall treat the
Transition Bonds as debt of the Seller for Federal income tax purposes.

     (b) So long as any of the Transition Bonds are outstanding, the Seller

Issuer in accordance with generally accepted accounting principles.

     (c) The Seller agrees that upon the sale by the Seller of the Transferred

to the Transferred Intangible Transition Property (other than the rights of an
electric distribution company set forth in Section 2807 of the Statute),
including the right to collect any amounts payable by any Customer or Third
Party in respect of such Transferred Intangible Transition Property,
notwithstanding any objection or direction to the contrary


<PAGE>


                                                                              29

by the Seller and (ii) any payment by any Customer or Third Party to the Issuer
shall discharge such Customer's or such Third Party's obligations in respect of
such Transferred Intangible Transition Property to the extent of such payment,
notwithstanding any objection or direction to the contrary by the Seller.

     (d) So long as any of the Transition Bonds are outstanding, (i) the Seller
shall not make any statement or reference in respect of the Transferred
Intangible Transition Property that is inconsistent with the ownership thereof
by the Issuer and (ii) the Seller shall not take any action in respect of the

<PAGE>


                                                                              30

and filed such filings, all in such manner and in such places as may be required
by law fully to preserve, maintain, and protect the interests of the Issuer in
the Transferred Intangible Transition Property, including all filings required
under the Statute relating to the transfer of the ownership or security interest
in the Transferred Intangible Transition Property by the Seller to the Issuer.
The Seller shall deliver (or cause to be delivered) to the Issuer file-stamped
copies of, or filing receipts for, any document filed as provided above, as soon
as available following such filing. The Seller agrees to take such legal or
administrative actions, including defending against or instituting and pursuing
legal actions and appearing or testifying at hearings or similar proceedings, as
may be reasonably necessary (i) to protect the Issuer and the Transition
Bondholders from claims, state actions or other actions or proceedings of third
parties which, if successfully pursued, would result in a breach of any
representation or warranty set forth in Article III or (ii) to block or overturn
any attempts to cause a repeal of, modification of or supplement to the Statute
or the Qualified Rate Orders or the rights of holders of Intangible Transition
Property by legislative enactment or constitutional amendment that would be
adverse to the holders of Intangible Transition Property.

     SECTION 4.09. Taxes. So long as any of the Transition Bonds are
outstanding, the Seller shall, and shall cause each of its subsidiaries (other
than the Issuer) to, pay all material taxes, including gross receipts taxes,
assessments and governmental charges imposed upon it or any of its properties or
assets or with respect to any of its franchises, business, income or property
before any penalty accrues thereon if the failure to pay any such taxes,
assessments and governmental charges would, after any applicable grace periods,
notices or other similar requirements, result in a lien on the Intangible
Transition Property; provided that no such tax need be paid if the Seller or one
of its subsidiaries is contesting the same in good faith by appropriate
proceedings promptly instituted and diligently conducted and if the Seller or
such subsidiary has established appropriate reserves as shall be required in
conformity with generally accepted accounting principles.

     (b) The Seller shall indemnify the Issuer and the Bond Trustee, for itself
and on behalf of the Transition Bondholders, and each of their respective
trustees, officers, directors and agents for, and defend and hold harmless each
such Person from and against, any and all taxes (other than any taxes imposed on
Transition Bondholders solely as a result of their ownership of Transition
Bonds) that may at any time be imposed on or asserted against any such Person as
a result of the acquisition or holding of the Transferred Intangible Transition
Property by the Issuer or the issuance and sale by the Issuer of the Transition
Bonds, including any sales, gross receipts, general corporation, tangible
personal property, privilege or license taxes.

     (c)(i) The Seller shall indemnify the Issuer and the Bond Trustee, on
behalf of the Transition Bondholders, each of their respective trustees,
officers, directors, and agents, and any Counterparty, and defend and hold
harmless each such Person from and against, any and all Losses that may be
imposed on, incurred by or asserted against any such Person as a result of (x)
the Seller's wilful misconduct, bad faith or gross negligence in the performance
of its duties or observance of its covenants under this Agreement, (y) the
Seller's reckless disregard of its obligations and duties under this Agreement
or (z) the Seller's breach of


<PAGE>


                                                                              33

any of its representations or warranties contained in this Agreement other than
those contained in Sections 3.08(b), 3.08(c), 3.08(d)(i), (ii) and (iv) and
3.08(f) (any event described in any of the foregoing clauses (x), (y) or (z), an
"Indemnification Event"); provided, however, that the amount of such Losses
(other than those payable pursuant to Section 5.01(e)) for which the Seller
shall be obligated to provide indemnification shall not exceed the Liquidated
Damages Amount. Amounts on deposit in the Reserve Subaccount, the
Overcollateralization Subaccount and the Capital Subaccount shall not be
available to satisfy any Losses for which indemnification is provided in this
Agreement.

     (ii) If an Indemnification Event shall occur, upon receipt of written
notice thereof by the Seller from the Issuer or the Bond Trustee, the Seller
shall notify the Servicer of the occurrence of such event so that the Servicer
may, pursuant to Section 8 of Annex 1 to the Master Servicing Agreement,
calculate (x) on the day which is 90 days after receipt of such notice by the
Seller (the "Initial Loss Calculation Date") the amount of Losses expected to be
incurred as a result of such Indemnification Event from and including the time
of its occurrence through and including the next Monthly Allocation Date after
the Initial Loss Calculation Date and (y) to the extent that


<PAGE>


                                                                              34

Losses may be incurred as a result of such Indemnification Event in an amount
exceeding the amount of Losses calculated pursuant to clause (x) above and
unless the Seller has paid Liquidated Damages with respect to such
Indemnification Event pursuant to Section 5.01(d)(i)(B), not later than each
Monthly Allocation Date succeeding the Initial Loss Calculation Date, the amount
of Losses expected to be incurred as a result of such Indemnification Event from
but excluding such Monthly Allocation Date through and including the next
Monthly Allocation Date. All such calculations shall be subject to the approval
of the Bond Trustee. If such Indemnification Event shall continue unremedied
beyond the Initial Loss Calculation Date, the Seller shall pay to the Bond
Trustee, as assignee of the Issuer, for deposit into the General Subaccount of
the Collection Account, (x) on the Monthly Allocation Date immediately following
the Initial Loss Calculation Date, the amount of Losses calculated pursuant to
clause (x) and clause (y) of the preceding sentence with respect to such Monthly
Allocation Date and (y) on each subsequent Monthly Allocation Date, the amount
of Losses calculated as of such date pursuant to clause (y) of the preceding
sentence. Upon payment pursuant to this Section 5.01(c)(ii), the Seller shall
have no further obligations with respect to such Losses to the extent of such
payments.

                                                                              35

     (d)(i) In the event of a breach by the Seller of any representation and
warranty specified in (A) Section 3.08(b), 3.08(c), 3.08(d)(i), (ii) or (iv) or
3.08(f) of this Agreement that has a material adverse effect on the Transition
Bondholders or (B) Sections 3.01, 3.03, 3.04, 3.05 and 3.08(d)(iii), (v) or (vi)
of this Agreement for which the full amount of Losses attributable thereto are
reasonably expected to be incurred beyond a 90-day period immediately following
the occurrence of such Indemnification Event, the Seller shall pay to the Bond
Trustee, as assignee of the Issuer, for deposit into the General Subaccount of
the Collection Account the Liquidated Damages Amount. Such amount shall be paid
(x) in the case of clause (A) above, on the Liquidated Damages Payment Date or
(y) in the case of clause (B) above, on the First Monthly Allocation Date
following the expiration of the 90-day period set forth in such clause (B).
Notwithstanding the foregoing, if the Seller is obligated pursuant to this
Section 5.01(d)(i) to pay amounts for deposit into the General Subaccount of the
Collection Account for a breach of a representation and warranty which relates
to one or more of the Qualified Rate Orders, but not all of the Qualified Rate
Orders, then the Liquidated Damages Amount will include the then outstanding
principal amount of only the Affected Transition Bonds as of


<PAGE>


                                                                              36

the Liquidated Damages Redemption Date and unpaid interest accrued thereon.

     (ii) The Seller shall not be obligated to pay the Liquidated Damages Amount
pursuant to Section 5.01(d)(i) (A) if (A) within 90 days after the date of the
occurrence thereof such breach is cured or the Seller takes remedial action such
that there is not and will not be a material adverse effect on the Transition
Bondholders as a result of such breach and (B) either (i) if the Seller had,
immediately prior to the breach, a long term debt rating of at least "A3" by
Moody's and "BBB" by Standard & Poor's and the equivalent of "BBB" by any other
Rating Agency, the Seller enters into a binding agreement with the Issuer to pay
any amounts necessary so that all interest payments due on the Transition Bonds
during such 90-day period will be paid in full, or (ii) if the Seller does not
have such long term debt ratings, the Seller deposits, within two Business Days
after such breach, an amount in escrow with the Bond Trustee sufficient, taking
into account amounts on deposit in the Collection Account which will be
available for such purpose, to pay all interest payments which will become due
on the Transition Bonds during such 90-day period. In the event that within such
90-day period (i) such breach is cured or (ii) the Seller takes the remedial
action specified by Section 5.01(d)(ii)(A), any amounts paid by the Seller to


<PAGE>


                                                                              37

the Bond Trustee, as assignee of the Issuer pursuant to Section 5.01(d)(ii)(B),
which have not been distributed pursuant to the Indenture shall be returned to
the Seller at the end of such 90-day period.

     (iii) With respect to any Losses described in Section 5.01(c)(ii) or
Section 5.01(d)(i)(B) above, the full amount of which is reasonably expected not
to exceed 1/12th of 1% of the annual outstanding balance of the Affected
Transition Bonds per Monthly Allocation Date (the "De Minimis Loss Amount"), the
Seller, on the Monthly Allocation Date immediately following the Initial Loss
Calculation Date, shall pay to the Bond Trustee, as assignee of the Issuer, for
deposit in the Loss Subaccount of the Collection Account, the aggregate expected
amount of such Losses for all Monthly Allocation Dates on which such Losses are
expected to be incurred, following which the Seller's obligation to pay
indemnification or Liquidated Damages, as applicable, as a result of such Losses
shall be waived so long as the actual Losses incurred on any Monthly Allocation
Date do not exceed the De Minimis Loss Amount. If the aggregate amount of such
Losses incurred as of any Monthly Allocation Date exceeds the amounts paid by
the Seller to the Bond Trustee, as assignee of the Issuer, with respect thereto,
the Seller shall pay to the Bond Trustee, as assignee of the Issuer, on the next
Monthly Allocation Date,


<PAGE>


                                                                              38

the amount of such excess for such Monthly Allocation Date and the expected
amount of excess for all subsequent Monthly Allocation Dates.

     (iv) Upon the payment by the Seller of the Liquidated Damages Amount
pursuant to Section 5.01(d)(i), neither the Issuer nor any other Person shall
have any other claims, rights or remedies against the Seller for a breach of the
representations and warranties specified in Section 3.08(b), (c), (d)(i),
(d)(ii), (d)(iv) or (f).

     (e) The Seller shall indemnify the Bond Trustee and the Issuer Trustee and
their respective officers, directors and agents for, and defend and hold
harmless each such Person from and against, any and all Losses that may be
imposed upon, incurred by or asserted against any such Person as a result of the
acceptance or performance of the trusts and duties contained herein and in the
Indenture, except to the extent that any such Loss shall be due to the wilful
misfeasance, bad faith or gross negligence of the Bond Trustee or the Issuer
Trustee, as applicable. Such amounts shall be deposited into the Collection
Account and distributed in accordance with the Indenture.

     (f) The Seller's indemnification obligations under Section 5.01(b),(c), (d)
and (e) for events occurring prior to the removal or resignation of the Bond
Trustee or the termination of this Agreement shall survive the


<PAGE>


                                                                              39

Account and distributed in accordance with the Indenture.

otherwise succeed to the major part of the electric distribution business of the
Seller, which Person in any of the foregoing cases executes an agreement of
assumption to perform every obligation of the Seller under this Agreement, shall

document or any further act by any of the parties to this Agreement; provided,
however, that (i) immediately after giving effect to such transaction, no

pursuant to the Statute, have been executed and filed that are necessary fully
to preserve and protect the interest of the Issuer in the Transferred Intangible
Transition Property and reciting the details of such filings or (B) stating
that, in the opinion of such counsel, no such action shall be necessary to
preserve and protect such interests. Notwithstanding anything herein to the
contrary, the execution of the above described agreement of assumption and
compliance with clauses (i), (ii), (iii) and (iv) above shall be conditions
precedent to the consummation of any transaction referred to in clauses (a),
(b), (c), (d) or (e) above.

     SECTION 5.03. Limitation on Liability of Seller and Others. The Seller and
any director or officer or employee or agent of the Seller may rely in good
faith on the advice of counsel or on any document of any kind, prima facie
properly executed and submitted by any Person, respecting any matters arising
hereunder. Subject to Section 5.04, the Seller shall not be under any obligation
to appear in, prosecute or defend any legal action that is not incidental to its

makes the following representations


                                       29

<PAGE>

and warranties as of each Transfer Date, on which the Issuers have relied and
will rely in acquiring Serviced Intangible Transition Property. The
representations and warranties shall survive the sale of any of the Serviced
Intangible Transition Property to any Issuer and the pledge thereof to any Bond
Trustee pursuant to any Indenture.

          (a) Organization and Good Standing. The Servicer is a corporation duly
     organized and in good standing under the laws of the state of its
     incorporation, with the corporate power and authority to own its properties
     and to conduct its business as such properties are currently owned and such
     business is presently conducted, and has the power, authority and legal
     right to service the Serviced Intangible Transition Property.

          (b) Due Qualification. The Servicer is duly qualified to do business
     as a foreign corporation in good standing, and has obtained all necessary
     licenses and approvals in, all jurisdictions in which the ownership or
     lease of property or the conduct of its business (including the servicing
     of the Serviced Intangible Transition Property as required by this
     Agreement) requires such qualifications, licenses or approvals (except
     where the failure to so qualify would not be reasonably likely to have a
     material adverse effect on the Servicer's business, operations, assets,

                                       30
<PAGE>

     revenues, properties or prospects or adversely affect the servicing of
     the Serviced Intangible Transition Property).

          (c) Power and Authority. The Servicer has the corporate power and
     authority to execute and deliver this Agreement and to carry out its terms;
     and the execution, delivery and performance of this Agreement have been
     duly authorized by the Servicer by all necessary corporate action.

          (d) Binding Obligation. This Agreement constitutes a legal, valid and
     binding obligation of the Servicer enforceable against the Servicer in
     accordance with its terms subject to bankruptcy, receivership, insolvency,
     fraudulent transfer, reorganization, moratorium or other laws affecting
     creditors' rights generally from time to time in effect and to general
     principles of equity (regardless of whether considered in a proceeding in
     equity or at law).

          (e) No Violation. The consummation of the transactions contemplated by
     this Agreement and the fulfillment of the terms hereof shall not conflict
     with, result in any breach of any of the terms and provisions of, nor
     constitute (with or without notice or lapse of time) a default under, the
     articles of incorporation or by-laws of the Servicer, or any

                                       31

<PAGE>

     indenture, agreement or other instrument to which the Servicer is a
     party or by which it shall be bound; nor result in the creation or
     imposition of any Lien (other than the lien of the Mortgage on the
     Servicer's interest in this Agreement) upon any of its properties pursuant
     to the terms of any such indenture, agreement or other instrument; nor
     violate any law or any order, rule or regulation applicable to the Servicer
     of any court or of any Federal or state regulatory body, administrative
     agency or other governmental instrumentality having jurisdiction over the
     Servicer or its properties.

          (f) Approvals. Except for filings with the PUC for revised Intangible
     Transition Charges pursuant to Section 4.01 and the Issuer Annexes and UCC
     continuation filings, no approval, authorization, consent, order or other
     action of, or filing with, any court, Federal or state regulatory body,
     administrative agency or other governmental instrumentality is required in
     connection with the execution and delivery by the Servicer of this
     Agreement, the performance by the Servicer of the transactions contemplated
     hereby or the fulfillment by the Servicer of the terms hereof, except those
     that have been obtained or made.


                                       32
<PAGE>


          (g) No Proceedings. There are no proceedings or investigations pending
     or, to the Servicer's best knowledge, threatened before any court, Federal
     or state regulatory body, administrative agency or other governmental
     instrumentality having jurisdiction over the Servicer or its properties:
     (i) except as disclosed by the Servicer to the Issuers, seeking any
     determination or ruling that might materially and adversely affect the
     performance by the Servicer of its obligations under, or the validity or
     enforceability against the Servicer of this Agreement or (ii) relating to
     the Servicer and which might adversely affect the Federal or state income
     tax attributes of the Transition Bonds.

          (h) Reports and Certificates. Each report and certificate delivered in
     connection with any filing made to the PUC by the Servicer on behalf of any
     Issuer with respect to Intangible Transition Charges or Intangible
     Transition Charges Adjustments will constitute a representation and
     warranty by the Servicer that each such report or certificate, as the case
     may be, is true and correct in all material respects; provided, however,
     that to the extent any such report or certificate is based in part upon or
     contains assumptions, forecasts or other predictions of future events, the
     representation and warranty of the

                                       33

<PAGE>

         Servicer with respect thereto will be limited to the representation and
         warranty that such assumptions, forecasts or other predictions of
         future events are reasonable based upon historical performance.

     SECTION 5.02. Indemnities of Servicer; Release of Claims. (a) The Servicer
shall be liable in accordance herewith only to the extent of the obligations
specifically undertaken by the Servicer under this Agreement.

     (b) The Servicer shall indemnify each Issuer and each Bond Trustee, for
itself and on behalf of the Transition Bondholders for which it acts as Bond
Trustee, and each of their respective trustees, officers, directors and agents
for, and defend and hold harmless each such Person from and against, any and all
Losses that may be imposed upon, incurred by or asserted against any such Person
as a result of (i) the Servicer's wilful misfeasance, bad faith or gross
negligence in the performance of its duties or observance of its covenants under
this Agreement or the Servicer's reckless disregard of its obligations and
duties under this Agreement or (ii) the Servicer's breach of any of its
representations or warranties in this Agreement.

     (c) If any action, claim, demand or proceeding (including any governmental
investigation) shall be brought or asserted against a party (the "indemnified
party") entitled to any indemnification provided for under this


                                       34
<PAGE>

Section 5.02, such indemnified party shall promptly notify the Servicer in
writing; provided, however, that failure to give such notification shall not
affect the indemnification provided hereunder except to the extent the Servicer
shall have been actually prejudiced as a result of such failure.

     (d) The Servicer shall indemnify the Bond Trustees and their respective
officers, directors and agents for, and defend and hold harmless each such
Person from and against, any and all Losses that may be imposed upon, incurred
by or asserted against any such Person as a result of the acceptance or
performance of the trusts and duties contained herein and in the Indenture,
except to the extent that any such Loss shall be due to the wilful misfeasance,
bad faith or gross negligence of the applicable Bond Trustee. Such amounts with
respect to the Bond Trustee of the First Issuer shall be deposited and
distributed in accordance with the Indenture to which such Bond Trustee is a
party.

     (e) The Servicer's indemnification obligations under Section 5.02(b) and
(d) for events occurring prior to the removal or resignation of any Bond Trustee
or the termination of this Agreement with respect to any Issuer shall survive
the resignation or removal of such Bond Trustee or the termination of this
Agreement with respect to such Issuer and shall include reasonable costs, fees
and

                                       35

<PAGE>


expenses of investigation and litigation (including any Issuer's and any Bond
Trustee's reasonable attorneys' fees and expenses).

     (f) Except to the extent expressly provided for in this Agreement, the Sale
Agreements or the Formation Documents (including the Servicer's claims with
respect to the Monthly Servicing Fees and the Seller's claim for payment of the
purchase price of Intangible Transition Property), the Servicer hereby releases
and discharges each Issuer (including its respective trustees, officers,
directors and agents, if any), and each Bond Trustee (including its respective
officers, directors and agents) (collectively, the "Released Parties") from any
and all actions, claims and demands whatsoever, which the Servicer, in its
capacity as Servicer or Seller, shall or may have against any such Person
relating to the Serviced Intangible Transition Property or the Servicer's
activities with respect thereto other than any actions, claims and demands
arising out of the wilful misconduct, bad faith or gross negligence of the
Released Parties.

     SECTION 5.03. Merger or Consolidation of, or Assumption of the Obligations
of, Servicer. Any Person (a) into which the Servicer may be merged or
consolidated and which succeeds to the major part of the electric distribution
business of the Servicer, (b) which results

                                       36

<PAGE>

from the division of the Servicer into two or more Persons and which succeeds to
the major part of the electric distribution business of the Servicer, (c) which
may result from any merger or consolidation to which the Servicer shall be a
party and which succeeds to the major part of the electric distribution business
of the Servicer, (d) which may succeed to the properties and assets of the
Servicer substantially as a whole and which succeeds to the major part of the
electric distribution business of the Servicer or (e) which may otherwise
succeed to the major part of the electric distribution business of the Servicer,
which Person in any of the foregoing cases executes an agreement of assumption
to perform every obligation of the Servicer hereunder, shall be the successor to
the Servicer under this Agreement without further act on the part of any of the
parties to this Agreement; provided, however, that (i) immediately after giving
effect to such transaction, no representation and warranty made pursuant to
Section 5.01 shall have been breached and no Servicer Default, and no event
which, after notice or lapse of time, or both, would become a Servicer Default,
shall have occurred and be continuing, (ii) the Servicer shall have delivered to
each Issuer and each Bond Trustee an Officers' Certificate and an Opinion of
Counsel each stating that such consolidation, merger or succession and such
agreement of assumption comply

                                       37
<PAGE>

with this Section 5.03 and that all conditions precedent provided for in this
Agreement relating to such transaction have been complied with, (iii) the Rating
Agencies shall have received prior written notice of such transaction, (iv) the
Servicer shall have delivered to each Issuer, each Bond Trustee and each Rating
Agency an Opinion of Counsel either (A) stating that, in the opinion of such
counsel, all filings, including filings with the PUC pursuant to the Statute,
have been executed and filed that are necessary to preserve fully and protect
fully the interests of each Issuer in the Serviced Intangible Transition
Property and reciting the details of such filings or (B) stating that, in the
opinion of such counsel, no such action shall be necessary to preserve and
protect such interests. Notwithstanding anything herein to the contrary, the
execution of the above referenced agreement of assumption and compliance with
clauses (i), (ii), (iii) and (iv) above shall be conditions precedent to the
consummation of the transactions referred to in clause (a), (b), (c), (d) or (e)
above.

     SECTION 5.04. Assignment of Servicer's Obligations. In each Qualified Rate
Order the PUC authorizes PECO Energy to contract with an alternative party to
perform PECO Energy's obligations contemplated in such Qualified Rate Order, and
under each such Qualified Rate

                                       38

<PAGE>

Order the Servicer may assign its obligations hereunder to any electric
distribution company (as such term is defined in the Statute) which succeeds to
the major part of PECO Energy's electric distribution business. Prior to any
such assignment, the Servicer shall provide written notice thereof to each of
the Rating Agencies.

     SECTION 5.05. Limitation on Liability of Servicer and Others. The Servicer
shall not be liable to any Issuer, except as provided under this Agreement, for
any action taken or for refraining from the taking of any action pursuant to
this Agreement or for errors in judgment; provided, however, that this provision
shall not protect the Servicer against any liability that would otherwise be
imposed by reason of wilful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of reckless disregard of obligations and
duties under this Agreement. The Servicer and any director or officer or
employee or agent of the Servicer may rely in good faith on the advice of
counsel reasonably acceptable to the Bond Trustees or on any document of any
kind, prima facie properly executed and submitted by any Person, respecting any
matters arising under this Agreement.

     Except as provided in this Agreement, the Servicer shall not be under any
obligation to appear in, prosecute or defend any legal action that is not
incidental to its duties

                                       39

<PAGE>


to service the Serviced Intangible Transition Property in accordance with this
Agreement or related to its obligation to pay indemnification, and that in its
reasonable opinion may cause it to incur any expense or liability.

     SECTION 5.06. PECO Energy Not To Resign as Servicer. Subject to the
provisions of Sections 5.03 and 5.04, PECO Energy shall not resign from the
obligations and duties hereby imposed on it as Servicer under this Agreement
except upon a determination that the performance of its duties under this
Agreement shall no longer be permissible under applicable law. Notice of any
such determination permitting the resignation of PECO Energy shall be
communicated to each Issuer, each Bond Trustee and each Rating Agency at the
earliest practicable time (and, if such communication is not in writing, shall
be confirmed in writing at the earliest practicable time), and any such
determination shall be evidenced by an Opinion of Counsel to such effect
delivered to each Issuer and each Bond Trustee concurrently with or promptly
after such notice. No such resignation shall become effective until a successor
Servicer shall have assumed the servicing obligations and duties hereunder of
PECO Energy in accordance with Section 6.04.

     SECTION 5.07. Monthly Servicing Fee. Each Issuer, severally and not
jointly, agrees to pay the

                                       40

<PAGE>

Servicer, solely to the extent amounts are available therefor in accordance with
the Indenture to which such Issuer is a party, the Monthly Servicing Fees with
respect to all Series of Transition Bonds issued by such Issuer. The Monthly
Servicing Fee with respect to a Series for a Monthly Allocation Date shall equal
the product of (a) 1/12, (b) the Servicing Fee Rate for such Series and (c) the
outstanding principal amount of the Transition Bonds of such Series as of such
Monthly Allocation Date. The Servicer will be entitled to retain as additional
compensation net investment income on ITC Collections related to Serviced
Intangible Transition Property received by the Servicer prior to each Remittance
Date and the late fees, if any, paid by Customers to the Servicer. The foregoing
fees constitute a fair and reasonable price for the obligations to be performed
by the Servicer.

     SECTION 5.08. Servicer Expenses. Except as otherwise expressly provided
herein, the Servicer shall be required to pay all expenses incurred by it in
connection with its activities hereunder, including fees and disbursements of
independent accountants and counsel, taxes imposed on the Servicer and expenses
incurred in connection with reports to Transition Bondholders.

     SECTION 5.09. Appointments. The Servicer may at any time appoint a
subservicer to perform all or any portion

                                       41
<PAGE>

of its obligations as Servicer hereunder; provided, however, that the Rating
Agency Condition shall have been satisfied in connection therewith with respect
to all Rating Agencies other than Moody's (and the Servicer shall have furnished
Moody's with written notice of such appointment prior to its effectiveness);
provided further that the Servicer shall remain obligated and be liable to each
Issuer for the servicing and administering of the Serviced Intangible Transition
Property in accordance with the provisions hereof without diminution of such
obligation and liability by virtue of the appointment of such subservicer and to
the same extent and under the same terms and conditions as if the Servicer alone
were servicing and administering the Serviced Intangible Transition Property.
The fees and expenses of the subservicer shall be as agreed between the Servicer
and its subservicer from time to time, and no Issuer (or trustee thereof, if
any), Bond Trustee or Transition Bondholder shall have any responsibility
therefor.

     SECTION 5.10. Remittances. (a) Subject to Section 5.07, the Servicer shall
remit all ITC Collections (from whatever source) allocated to each Issuer
pursuant to Section 3.02 and all proceeds of other Collateral of such Issuer, if
any, received by the Servicer to the Bond Trustee under the Indenture to which
such Issuer is a party, for

                                       42
<PAGE>

deposit pursuant to such Indenture, not later than the second Business Day after
receipt thereof.

     (b) Notwithstanding the foregoing clause (a), (i) as long as PECO Energy or
any successor to PECO Energy's electric distribution business remains the
Servicer, (ii) no Servicer Default has occurred and is continuing and (iii) (A)
PECO Energy or such successor maintains a short- term rating of "A-1" or better
by Standard & Poor's, "P-1" or better by Moody's and, if rated by Fitch IBCA,
"F-2" by Fitch IBCA (and for five Business Days following a reduction in any
such rating) or (B) the Rating Agency Condition shall have been satisfied (and
any conditions or limitations imposed by the Rating Agencies in connection
therewith are complied with), the Servicer need not make the daily remittances
required by such clause (a), but in lieu thereof, shall remit all ITC
Collections (from whatever source) allocated to each Issuer pursuant to Section
3.02 and all proceeds of other Collateral of such Issuer, if any, received by
the Servicer during each Collection Period and any such amounts received in
prior Collection Periods but not so remitted to the Bond Trustee under the
Indenture to which such Issuer is a party, for deposit pursuant to such
Indenture, not later than the final day of such Collection Period or, if any
such day is not a Business Day, the next succeeding Business Day.

                                       43

<PAGE>

     SECTION 5.11. Servicer Advances. The Servicer shall make advances of
interest or principal on the Transition Bonds of any Series in the manner and to
the extent, if any, specified in any Annex to this Agreement entered into in
connection with the issuance of such Transition Bonds.

     SECTION 5.12. Protection of Title. The Servicer shall execute and file such
filings, including filings with the PUC pursuant to the Statute, and cause to be
executed and filed such filings, all in such manner and in such places as may be
required by law fully to preserve, maintain, and protect the interests of each
Issuer in its respective Serviced Intangible Transition Property, including all
filings required under the Statute relating to the transfer of the ownership or
security interest in the Serviced Intangible Transition Property by the Seller
to such Issuer or any security interest granted by such Issuer in its Serviced
Intangible Transition Property. The Servicer shall deliver (or cause to be
delivered) to the applicable Issuers file-stamped copies of, or filing receipts
for, any document filed as provided above, as soon as available following such
filing.

                                       44

                                Servicer Default

     SECTION 6.01. Servicer Default. If any one of the following events (a
"Servicer Default") shall occur and be continuing:

          (a) any failure by the Servicer to remit to any Bond Trustee on behalf
     of an Issuer any required remittance that shall continue unremedied for a
     period of three Business Days after written notice of such failure is
     received by the Servicer from such Issuer or Bond Trustee; or

          (b) any failure by the Servicer or, so long as the Seller and the
     Servicer are the same Person, the Seller, as applicable, duly to observe or
     perform in any material respect any other covenant or agreement of the
     Servicer or the Seller, as the case may be, set forth in this Agreement or
     any other Basic Document to which it is a party, which failure shall (i)
     materially and adversely affect the Intangible Transition Property and (ii)
     continue unremedied for a period of 30 days after written notice of such
     failure shall have been given to the Servicer or the Seller, as the case
     may be, by any Issuer or any Bond Trustee or after discovery of such
     failure by an officer of the Servicer or the Seller, as the case may be; or

                                       45

<PAGE>


          (c) any representation or warranty made by the Servicer in this
     Agreement shall prove to have been incorrect when made, which has a
     material adverse effect on any of the Issuers or the Transition Bondholders
     and which material adverse effect continues unremedied for a period of 60
     days after the date on which written notice thereof shall have been given
     to the Servicer by any Issuer or any Bond Trustee; or

          (d) an Insolvency Event occurs with respect to the Servicer;

then, and in each and every case, so long as the Servicer Default shall not have
been remedied, Bond Trustees, as assignees of the applicable Issuers, with
respect to Holders of a majority of the outstanding principal amount of the
Transition Bonds, by notice then given in writing to the Servicer (a
"Termination Notice") may terminate all the rights and obligations (other than
the indemnification obligations set forth in Section 5.02 hereof and the
obligation under Section 6.02 to continue performing its functions as Servicer
until a successor Servicer is appointed) of the Servicer under this Agreement
with respect to all the Issuers. In addition, upon a Servicer Default described
in Section 6.01(a), each of the following shall be entitled to apply to the PUC
for sequestration and payment of revenues arising with respect to the Serviced
Intangible

                                       46

<PAGE>

Transition Property: (i) each Issuer or its assignees or (ii) pledgees or
transferees, including transferees under the Statute, of the Serviced Intangible
Transition Property. On or after the receipt by the Servicer of a Termination
Notice, all authority and power of the Servicer under this Agreement with
respect to the Issuers, whether with respect to the Serviced Intangible
Transition Property, the related Intangible Transition Charges or otherwise,
shall, upon appointment of a successor Servicer pursuant to Section 6.02,
without further action, pass to and be vested in such successor Servicer and,
without limitation, each Bond Trustee is hereby authorized and empowered to
execute and deliver, on behalf of the predecessor Servicer, as attorney-in-fact
or otherwise, any and all documents and other instruments, and to do or
accomplish all other acts or things necessary or appropriate to effect the
purposes of such Termination Notice, whether to complete the transfer of the
Intangible Transition Property Documentation and related documents, or
otherwise. The predecessor Servicer shall cooperate with the successor Servicer,
the Bond Trustees and the Issuers in effecting the termination of the
responsibilities and rights of the predecessor Servicer under this Agreement,
including the transfer to the successor Servicer for administration by it of all
cash amounts that shall at the time be held by the predecessor

                                       47

<PAGE>

Servicer for remittance, or shall thereafter be received by it with respect to
the Serviced Intangible Transition Property or the related Intangible Transition
Charges. As soon as practicable after receipt by the Servicer of such
Termination Notice, the Servicer shall deliver the Intangible Transition
Property Documentation to the successor Servicer. All reasonable costs and
expenses (including attorneys fees and expenses) incurred in connection with
transferring the Intangible Transition Property Documentation to the successor
Servicer and amending this Agreement to reflect such succession as Servicer
pursuant to this Section shall be paid by the predecessor Servicer upon
presentation of reasonable documentation of such costs and expenses. Termination
of PECO Energy as Servicer shall not terminate PECO Energy's rights or
obligations as Seller under any of the Sale Agreements.

     SECTION 6.02. Notice of Servicer Default. The Servicer shall deliver to
each Issuer, each Bond Trustee and each Rating Agency promptly after having
obtained knowledge thereof, but in no event later than five Business Days
thereafter, written notice in an Officers' Certificate of any event or
circumstance (such as a breach of any representation or warranty made by the
Servicer in this

                                       48

<PAGE>

Agreement) which, with the giving of notice or the passage of time, would become
a Servicer Default under Section 6.01.

     SECTION 6.03. Waiver of Past Defaults. All the Bond Trustees acting
together may waive in writing any default by the Servicer in the performance of
its obligations hereunder and its consequences, except a default in making any
required remittances to any Bond Trustee of ITC Collections from Serviced
Intangible Transition Property in accordance with Section 5.10 of this
Agreement. Upon any such waiver of a past default, such default shall cease to
exist, and any Servicer Default arising therefrom shall be deemed to have been
