     The Form U-1 Application/Declaration filed June 9, 2000, as amended January
4, 2001, in this file number 70-9691 is hereby amended in its entirety as
follows:

Item 1.  Description of the Proposed Transaction

     A.  Introduction

         1.   Summary of Request

     Exelon Corporation, a Pennsylvania Corporation ("Exelon")/1/, on behalf of
itself and the Subsidiaries (as defined below) files this
Application/Declaration under the Public Utility Holding Company Act of 1935
(the "Act") seeking authority to make investments in:

         .    infrastructure services businesses which are functionally related
         to its business as an integrated public utility company; and

         .    energy related businesses that, but for being conducted outside
         the United States, would constitute Rule 58 exempt activities of a type
         and in locations that the Commission has not had an opportunity to
         consider to date.

         2.   Description of the Parties to the Transaction

     Exelon has three principal operating public utility company subsidiaries
(the "Utility Subsidiaries")/2/:

         .    PECO Energy Company ("PECO"), a Pennsylvania corporation and a
         public utility company engaged (i) in the transmission, distribution
         and sale of electricity and (ii) in the purchase and sale of natural
         gas in Pennsylvania;



_________________________________

     /1/ Exelon filed an Application-Declaration on Form U-1 (File No.70-09645)
(the "Merger U-1") on March 16, 2000 and was created through transactions
referred to therein as the Merger that were completed October 20, 2000,
subsequent to the Commission issuing its order approving the Merger (the "Merger
Order") (HCAR No. 35-27256, October 19, 2000, modified in HCAR No. 35-27259,
October 20, 2000). On April 4, 2001, December 14, 2001, December 20, 2001, May
30, 2002 and June 27, 2002 Exelon filed a post-effective amendment on Form U-1
in file No. 70-9645 seeking modification of the Merger Order relating to certain
Subsidiaries providing services to and from the Utility Companies at other than
cost. On October 1, 2001, Exelon filed a post-effective amendment on Form U-1 in
file No. 70-9645 seeking final approval of matters relating to Exelon Business
Services Company, Exelon's service company. The Commission entered its order on
November 2, 2000 (HCAR No. 35-27266; 70-9693) as supplemented on December 8,
2000 (HCAR No. 35-27296) (the "Financing Order") approving certain financing
transactions for Exelon and its Subsidiaries. Exelon filed an
Application/Declaration on Form U-1 (Docket 70-10050) seeking approval for some
of the activities for which approval was sought in the previous amendment filed
in this docket. The subject matters included in that new docket have been
removed from this filing and are subject to the order in Exelon Corporation,
Holding Co. Act Rel. No. 35-27547 (June 27, 2002). The remaining matters in this
filing relate to subjects for which approval was originally sought in June 2000.

     /2/ For purposes of this filing, "Utility Subsidiaries" also includes
Commonwealth Edison Company of Indiana, PECO Energy Power Company, Susquehanna
Power Company and Susquehanna Electric Company.

                                        1



         .  Commonwealth Edison Company ("ComEd"), an Illinois corporation and a
         public utility company engaged in the transmission, distribution and
         sale of electricity in Illinois; and

         .  Exelon Generation Company, LLC ("Genco"), a Pennsylvania limited
         liability company and a public utility company engaged in the
         generation and sale of electricity in Pennsylvania, Illinois and
         elsewhere and also engaged in electricity and energy commodities
         marketing and brokering activities and development and ownership of
         EWGs./3/

     In addition, Exelon has the following other principal Subsidiaries:

         .  Exelon Energy Delivery Company, LLC ("Delivery"), the intermediate
         holding company for ComEd and PECO;

         .  Exelon Business Services Company ("Exelon Services"), the service
         company for the Exelon System;

         .  Exelon Ventures Company, LLC ("Ventures"), a non-utility company and
         a first tier Subsidiary of Exelon which has as wholly-owned
         subsidiaries, Genco and Exelon Enterprises Company, LLC
         ("Enterprises");/4/ and

         .  Enterprises, the principal Subsidiary through which Exelon will
         conduct its non-utility businesses.

     Each of the directly or indirectly owned subsidiaries of Exelon as of the
date hereof is referred to herein individually as a "Subsidiary" and
collectively as "Subsidiaries." All of Exelon's direct and indirect
Subsidiaries, other than the Utility Subsidiaries, are herein called the
"Non-Utility Subsidiaries."

     For purposes of this Application-Declaration, the terms "Subsidiary" and
"Subsidiaries" shall also include other direct or indirect subsidiaries that
Exelon may form or acquire after the date hereof with the approval of the
Commission, pursuant to the Rule 58 exemption or pursuant to Sections 32, 33 or
34 of the Act or otherwise expressly approved by the Commission./5/ Exelon and
the Subsidiaries are sometimes hereinafter collectively referred to as the
"Exelon System" or as the "Applicants."


____________________

     /3/ See the Merger U-1 regarding the corporate structure of Genco and the
authority requested for certain interim operations regarding generating
activities pending the completion of the Restructurings.

     /4/ As described in the Merger U-1, formation of Ventures was necessary to
achieve the desired corporate reorganization of the Unicom Non-Utility
Subsidiaries and the PECO Non-Utility Subsidiaries without incurring substantial
income tax liability.

     /5/ In Exelon Corporation, Holding Co. Act Rel. No. 35-27547 (June 27,
2002), Exelon received authority to invest in businesses engaged in energy
related activities ("Non-U.S. Energy Related Subsidiaries) that, but for being
conducted outside the United States, would constitute Rule 58 exempt activities.
Approval obtained in that order is only of activities that the Commission has
authorized for other registered holding companies in the past.

                                        2



         3.   Status of Restructurings

     As part of the Merger creating Exelon, the Commission approved certain
corporate reorganization steps involving the separation of the businesses of the
pre-merger companies into three business lines - energy delivery, energy
generation and non-utility activities. All elements of the Restructurings are
complete:

         .    The generating assets of ComEd and PECO were transferred to Genco
         effective January 1, 2001;

         .    Genco became the parent holding company effective January 1, 2001
         for PECO Energy Power Company ("PEPCO"), Susquehanna Power Company
         ("SPCO") and Susquehanna Electric Company ("SECO" and together with
         PEPCO and SPCO, the "Conowingo Companies") which lease and operate the
         Conowingo hydroelectric project;/6/

         .    The exempt wholesale generator ("EWG") business of PECO -- AmerGen
         Energy Company, L.L.C. ("AmerGen") -- became a subsidiary of Genco
         effective January 1, 2001;

         .    Ventures was established as the parent holding company for Genco
         and Enterprises and substantially all of the Non-Utility Subsidiaries
         were reorganized to be Subsidiaries of Enterprises effective January 1,
         2001;/7/

         .    Delivery was established as the parent holding company for ComEd
         and PECO effective April 18, 2001;/8/

         .    Genco has assumed the marketing efforts of PECO and ComEd/9/ and
         substantially all existing contracts have been assigned to or assumed
         by Genco; and

         .    Exelon filed the appropriate certificate of notification regarding
         the Restructurings on June 3, 2002.

     B.  Infrastructure Service Businesses

     In the Merger Order, the Commission approved the retention by Exelon of the
businesses organized as Exelon Infrastructure Services ("EIS"). EIS has since
been renamed as "InfraSource, Inc." and will be referred to herein as "ISI." The
companies encompassed within the former EIS are described on pages A-23 through
A-29 of the Merger Order.

________________

     /6/ Genco filed a Form U5A Notification of Registration on January 23,
2001.

     /7/ Ventures filed a Form U5A Notification of Registration on January 23,
2001.

     /8/ Delivery filed a Form U5A Notification of Registration on June 4, 2001.

     /9/ See Merger Order at note 26.

                                        3



     The infrastructure services and related businesses are characterized in
North America by a large number of relatively small companies. ISI has grown
through acquisitions of a number of these companies. As demonstrated in the
Merger Order, these businesses are all primarily in the infrastructure services
and related businesses but frequently are not organized neatly into exactly the
categories of activity that are clearly permitted by Rule 58. The fact that this
industry, while predominantly "energy related" is not exclusively so was
considered by the Commission in the Merger Order. The Commission found that
these businesses, as so constituted at that time, were of a type that a
registered holding company could retain./10/ This finding in Exelon's case was
consistent with past Commission decisions./11/

     Exelon seeks permission herein to retain and expand its holdings in this
area subject to the limitations set out herein. The Commission has approved
generic approval for acquisitions of businesses that are functionally related
but may not be exempt./12/

     In the Merger U-1, Exelon demonstrated that it could retain the
infrastructure services and related businesses by showing that approximately 75%
of the aggregate revenues of the ISI companies were derived from the portion of
the business that is engaged in traditional infrastructure service functions
("Traditional Infrastructure Businesses"). Traditional Infrastructure Businesses
include the construction of electric "transmission and distribution" facilities,
substation construction, utility pipelines and other utility facilities,13 meter
reading and installation and fiber-optic cable installation (which requires
similar skills and equipment to the services related above and relates to
activities that are exempt under Section 34 of the Act). The remaining 25% of
revenues were derived from related activities including inside
telecommunications wiring where the customers are industrial and commercial
concerns, telecommunications installation and a small amount of other activities
("Approved Related Activities")./14/

     Thus, as was shown in the Merger U-1, ISI companies' revenues were and
continue to be predominantly derived from the utility related activities of the
Traditional Infrastructure Businesses. Exelon's businesses were, and continue to
be, comparable to similar infrastructure services company groups the Commission
has permitted registered holding companies to acquire as "functionally related"
businesses or to retain in connection with merger transactions./15/ In fact,

2001) (generic authority to make investments in energy related activities in the
United States and Canada of a type specified in U-1 subject to overall dollar
limitation.)

     /13/ Work for utilities will include electric, gas, water, sewer and
telecommunications utilities as customers.

     /14/ ISI's activities (percent of revenues) for the quarter ended March 31,
2002 were as follows: T&D electric, 20.7%, substation construction, 20.8%,
underground gas utility, 18.4%, meter reading and installation, 5.3%, fiber
optic/cable installation, 5.2%, other related (cable trench work, fiber related
smart traffic) 4.9%. These categories total 75.3% of revenues. The "non-utility"
businesses contribute the remaining 24.7% as follows: I&C (inside electrical),
22.5% and telecommunications installation, 2.3%.

     /15/ GPU, Inc., Holding Co. Act Rel. No. 35-27165 (April 14, 2000).
FirstEnergy Corp., Holding Co. Act Rel. No. 35-27459 (Oct. 29, 2001).

                                        4



in some respects ISI represents a more "utility" related mix than the
Commission's other precedent in this area./16/

     In addition to ISI, Exelon owns three other related businesses. Exelon
Services ("ES") which provides services in heating, cooling, ventilation and
industrial process systems, high and low voltage electrical power systems,
lighting, environmental control, voice, video and data systems, building
automation, security and access control and security systems, fire protection
and plumbing systems and related activities, as well as energy performance
contracting, turnkey energy and operational systems and distributed
generation./17/ UT Holding Inc. provides district cooling and energy
systems./18/ Exelon Capital Partners, Inc. maintains and manages intangible
investments primarily in new and developing businesses related to the core
businesses of infrastructure, mechanical, energy and thermal services./19/

     To the extent not exempt under Rule 58, Exelon seeks authority to continue
to retain existing companies and to acquire additional infrastructure,
mechanical, energy and thermal service companies so long as the following
safeguards and conditions are met:

     First, taking each company including new acquisitions into account, at
least 60% of the groups' total aggregate revenues must be derived substantially
from Traditional Infrastructure Businesses as described above and/or other clear
Rule 58 activities such as mechanical, energy and thermal services./20/

     Second, the remaining amount of the groups' total aggregate revenues (not
more than 40%) must be derived substantially from Approved Related Activities.

     Third, while a particular company that is held would not itself have to
meet the 60% - 40% test, no acquisition could be made unless, taking into
account all companies, the


_________________

     /16/ Id. The MYR Group, Inc. acquired by GPU in that case derived its
revenues as follows: T&D Services (construction and maintenance of transmission
and distribution power lines and substations) 54%; Telecommunications
(construction of telecommunications towers, installation of fiber optic and
copper cables and certain telephone or communication systems) 10% and C&I
Services (electrical system wiring for commercial and industrial customers),
33%. The activities classified as "telecommunications" in MYR include more
activities than ISI includes in its "fiber optic" category. Thus, a truly
comparable percentage of the "utility related" activities of MYR, as that term
was used by ISI in the Merger Order, would be something greater than 54% and
less than 64%. Accordingly, Exelon believes its proposed 60% rule is consistent
with the GPU precedent.

     /17/ ES is a merged company consisting of entities known at the time of the
Merger as Unicom Mechanical Services and Unicom Energy Services Inc. See pages
A-1 through A-3 of the Merger Order.

     /18/ Exelon seeks authority to engage in thermal business outside the
United States. See Item 1. C. below.

     /19/ See pages 1-13 of Exhibit I-1 of the Merger U-1 for a complete
description of the services provided by these companies.

     /20/ As noted, under the Merger Order Exelon is authorized to hold ISI and
its subsidiaries so long as ISI is predominantly (i.e., 75%) utility related
infrastructure services. Under the authority granted in Docket 70-10050, Exelon
may reorganize its corporate structure from time to time. Accordingly, Exelon
may have more than one Subsidiary "group" that satisfies the test described
above.

                                        5



aggregate revenues of all companies are at least 60% from Traditional
Infrastructure Businesses./21/

       Fourth, the business of Exelon's infrastructure groups would be limited
to engaging predominantly in only the activities approved by the Commission as
described in the Merger Order, i.e., Traditional Infrastructure Businesses and
Approved Related Activities. Thus, the approval requested would not give Exelon
carte blanche to invest in any type of business so long as it was diluted in the
overall infrastructure services business. Only businesses of the type already
reviewed and found acceptable could be acquired.

       Fifth, Exelon's aggregate investment in company groups pursuant to the
preceding paragraph will be considered as "Rule 58" investments and will count
against Exelon's Rule 58 Subsidiary investment limitation.

       The Commission has found the method proposed herein, of reviewing
proposed new investments on a generic basis, to be reasonable and appropriate
under the Act. The generic approval theory underlies the exemption given in Rule
58. Under that rule, specific case-by-case approval is not required for
acquisition of energy related companies as defined under that Rule. In a recent
case, the Commission used this same generic approval approach to allow the
holding company system to acquire from time to time energy related businesses
falling within a specific generic description subject to an overall dollar
investment limitation./22/ Because, as noted, the North American infrastructure
industry is characterized by the large number of smaller companies, unless the
Commission grants Exelon the approval requested herein, Exelon will either have
to forego attractive investment opportunities or seek individual Commission
approval for each small transaction. Seeking individual approval would
substantially increase the burdens on Exelon's business and the Commission's
staff time and resources without any significant additional benefit to the
public interest.

       With the safeguards listed above, and given that the proposed
acquisitions closely relate to Exelon's utility business and its already
approved infrastructure services business, Exelon believes that the proposed
authority will be appropriate and in compliance with the Act.

       C.  Sale Of Certain Goods And Services Outside The United States.

       In docket 70-10050, Exelon received approval by the Commission to engage
through Subsidiaries in energy related activities ("Non-U.S. Energy Related
Activities") that, but for being conducted outside the United States, would
constitute Rule 58 exempt activities./23/ Under that approval, Non-U.S. Energy
Related Activities are limited to activities of the type the

seeks to expand the list of permitted activities to include types of businesses
and locations outside the United States that the Commission has not had occasion
to consider before.

            1.  Approval Sought for Limited Activities

       Approval is sought to engage in sales of only the following activities
outside the United States:

       "Infrastructure Services." Utility infrastructure services, including the
services provided by ISI, such as installing and maintaining underground
communications and energy networks, high voltage transmission and distribution
lines, substations and towers for electric and telecommunications companies,
construction and ongoing maintenance services to industrial and municipal owners
of complex electric and communications infrastructures on a nationwide basis,
management of large volumes of technical service and repair work for
communications and energy utilities and new residential design and construction
services, permitting a single point of contact for the design and construction
of all utility infrastructures (including electric, gas, water, sewer, cable and
telephone) and outdoor lighting./25/

       "Thermal Services." Thermal services such as chilled water, steam,
district heating and cooling and similar services./26/

            2.  Location of Activities Limited

       Exelon requests authority to engage in the requested energy related
activities only in the locations listed below:


       ---------------------------------------------------------------------
       Activity                        Location
       ---------------------------------------------------------------------
       Infrastructure Services         Canada, Mexico and the countries of
                                       the Caribbean/27/

       ---------------------------------------------------------------------
       Thermal Services                Canada and Mexico
       ---------------------------------------------------------------------

            3.  Exelon's Request is Substantially Similar to Precedent, Does not
                Create Additional Risks and Should be Approved

       As noted, the Commission has on a number of occasions approved activities
which would qualify for Rule 58 but for the fact that they were conducted
outside the United States. Exelon believes that the activities listed above for
which approval is sought are not substantively different from those already
approved to be conducted outside the U.S.

                a.   Infrastructure Services

       Exelon requests authority to engage in Infrastructure Services in Canada,
Mexico and the Caribbean. These services are also closely related to Exelon's
core utility competence. The Infrastructure Services activities include many of
the main activities that the Utility Companies engage in - installing and
maintaining energy networks, high voltage transmission and distribution lines,
substations and towers for electric and telecommunications companies and
permitting a single point of contact for the design and construction of all
utility infrastructures, for example.

       It would not be unusual for a foreign utility company ("FUCO") to perform
these types of services and Exelon would thus be permitted to engage in many of
these activities directly through any FUCO it owned. Exelon, however, does not
currently own any FUCOs. There does not appear to be any basis for
distinguishing between providing these services through a FUCO or through a Rule
58 Subsidiary which is approved to provide the services in Canada, Mexico and
the Caribbean. Furthermore, requiring Exelon to conduct these activities through
FUCOs would take away some of the efficiency of conducting such activities
directly by Rule 58 Subsidiaries that already have the know-how and expertise in
conducting such activities. For these reasons, and the further general reasons
noted below, Exelon believes that the Commission should approve Infrastructure
Services in Canada, Mexico and the Caribbean.

______________________

       /27/ This would include all of the island countries or territories in the
Caribbean except Cuba (including The Bahamas, Jamaica, Cayman Islands, Haiti,
Dominican Republic, British Virgin Islands, Barbados, Aruba, Trinidad and
Tobago). Exelon considers Puerto Rico and the U.S. Virgin Islands as part of the
United States.

                                        8



               b.   Thermal Services

       With respect to Thermal Services, Exelon already provides these services
in Canada and requests authority to provide such services in Canada and Mexico.
In the Merger Order, the Commission reserved jurisdiction over the retention by
Exelon of certain thermal businesses which operate in Canada (Northwind Thermal
Technologies Canada, Inc., Unicom Thermal Technologies Inc., Edison Finance
Partnership, and Edison Development Canada Inc.). All of these companies are
either directly engaged in providing Thermal Services or were created for tax
and financing purposes to facilitate the investment in the operating companies.
Exelon requests that this filing be considered a request for the Commission to
release jurisdiction over the retention of those businesses.

       In addition to the energy management, consulting and energy marketing
activities noted above which the Commission has allowed in Canada, it has also
allowed development, exploration and production of natural gas and oil in
Canada./28/ Exelon submits that the risks associated with the Thermal Services
which it conducts in Canada are not greater than the risks associated with oil
and gas exploration and development or energy marketing and trading. Further,
like the energy management and energy consulting, Thermal Services are closely
related to Exelon's core activities. Thermal Services include construction and
operation of facilities that are very similar to electric generation and
distribution or gas distribution. For these reasons, and the further general
reasons noted below, Exelon believes that the Commission should approve Thermal
Services in Canada and Mexico.

               c.   General Reasons to Approve Request

       Exelon believes that the Commission can and should expand the ability of
registered holding companies to engage in Rule 58 activities outside the United
States for the following reasons. When Rule 58 was proposed, it did not contain
a limitation that Rule 58 activities be confined to the United States./29/ When
the Rule was adopted, however, the Commission inserted the "in the United
States" requirement in Rule 58(b)(1) and (2). The only discussion of this change
is found in a footnote to the release adopting the Rule. That footnote indicates
the change was included based on then existing precedent and the markets with
which the Commission was then familiar./30/ As demonstrated by the precedent
cited above, the Commission is now familiar with a number of matters where Rule
58 activities conducted outside the United States have been approved.
Furthermore, since the adoption of Rule 58 the Commission has had extensive
experience with FUCOs and investments in United States registered holding
companies by non-U.S. entities. The Commission has recognized the globalization
of the utility industry and the need for U.S. utilities to remain
competitive./31/

       Exelon does not believe that any of the activities described herein
involve any unusual risk merely because they may be conducted outside the United
States. To the extent that non-U.S. operations involve additional or different
risks than U.S. operations, Exelon will evaluate and seek to mitigate those
risks in a manner similar to the manner it evaluates EWG and FUCO investments as
described in Amendment No. 4 to the Form U-1 filed in File No. 70-9693 filed
December 5, 2000. The Commission has recognized that a careful and structured
review of risks by the investing company pursuant to a detailed policy adopted
by its board of directors is the best way to identify and mitigate risks./32/

       Exelon does not believe that there are any risks in the activities listed
above that are significantly different from the risks related to other
activities which the Commission has approved be conducted outside the U.S.
Although many of the existing orders have involved activities permitted in
Canada and Mexico, they also have involved several other countries. Importantly,
there is no limitation on world-wide location for EWGs or FUCOs under the Act.
In allowing U.S. registered holding companies to participate in the global
energy markets, Congress did not feel any need to restrict the location in the
world where such activities could be undertaken. The Commission has relied on
the risk identification and mitigation procedures of applicants to ensure that
non-U.S. activities of EWGs and FUCOs, where ever located in the world, would
not result in the harms sought to be avoided by the statute. The Commission can
rely on the same protections for Rule 58 activities. Accordingly, there appears
to be no basis to restrict Rule 58 activities to only those countries which have
been mentioned in the existing precedent.

       Thus, there would not appear to be any basis for concluding that the
activities listed above should be restricted only to the U.S. Accordingly, the
Commission should approve Exelon's request as noted above.

       D.     Rule 54

       The proposed transaction is also subject to the requirements of Rule 54.
Rule 54 provides that in determining whether to approve the issue or sale of a
security by a registered holding company for purposes other than the acquisition
of an EWG or FUCO, or other transactions by such registered holding company or
its subsidiaries other than with respect to EWGs or FUCOs, the Commission shall
not consider the effect of the capitalization or earnings of any subsidiary
which is an EWG or a FUCO upon the registered holding company if paragraphs (a),
(b) and (c) of Rule 53 are satisfied.

       Exelon currently does not meet all of the conditions of Rule 53(a). As of
March 31, 2002, Exelon's "aggregate investment," as defined in Rule 53(a)(1), in
EWGs and FUCOs was approximately $1,353 million which is in excess of the 50% of
Exelon's average consolidated retained earnings of $1,006 million at March 31,
2002 which is the "safe harbor" limitation contained in Rule 53(a). However, by
orders dated November 2, 2000 and December 8, 2000 (HCAR Nos. 27266 and 27296,
together the "Financing Orders"), the Commission has authorized Exelon to
increase its "aggregate investment" in EWGs and FUCOs to an amount of

____________________
       /32/ The Commission explained this view in its release regarding the
re-proposal of Rule 55 which would regulate investments in FUCOs. See Holding
Co. Act Release No. 35-27342 (Feb. 7, 2001) at note 35.

                                       10



up to $4 billion. Therefore, although Exelon's "aggregate investment" in EWGs
and FUCOs currently exceeds the 50% "safe harbor" limitation, this investment
level is permitted under the Financing Orders.

       In any event, even taking into account the capitalization of and earnings
from EWGs and FUCOs in which Exelon has an interest, there would be no basis for
withholding approval of the proposed transaction. With regard to capitalization,
since the issuance of the Financing Orders, there has been no material adverse
impact on Exelon's consolidated capitalization resulting from Exelon's
investments in EWGs and FUCOs. At March 31, 2002, Exelon's consolidated
capitalization consists of 34 % equity, 3% preferred securities, 61% long-term
debt (including current maturities of long-term debt), and 2% short-term debt.
These ratios are within acceptable industry ranges. The proposed transaction
will not have any material impact on capitalization. Further, since the date of
the Financing Orders, there has been no material change in Exelon's level of
earnings from EWGs and FUCOs.

       Exelon satisfies all of the other conditions of paragraphs (a) and (b) of
Rule 53. With reference to Rule 53(a)(2), Exelon maintains books and records in
conformity with, and otherwise adheres to, the requirements thereof. With
reference to Rule 53(a)(3), no more than 2% of the employees of Exelon's
domestic public utility companies render services, at any one time, directly or
indirectly, to EWGs or FUCOs in which Exelon directly or indirectly holds an
interest. With reference to Rule 53(a)(4), Exelon will provide a copy of each
application and certificate relating to EWGs and FUCOs and relevant portions of
its Form U5S to each regulator referred to therein, and will otherwise comply
with the requirements thereof concerning the furnishing of information. With
reference to Rule 53(b), none of the circumstances enumerated in subparagraphs
(1), (2) and (3) thereunder have occurred. Finally, Rule 53(c) by its terms is
inapplicable since the proposed transaction does not involve the issue or sale
of a security to finance the acquisition of an EWG or FUCO.
