         the findings of such audit, if adversely determined, would result in a
         Material Adverse Effect. All taxes, including withholding taxes,
         penalties and interest, assessments, fees and other charges due or
         claimed to be due from such entities have been paid, other than those

         provided or those currently payable without penalty or interest and

expenses connected with any offers they may make. The fees and disbursements of

section will be, in the aggregate, $7,500.

         8.   The respective obligations of the Underwriters and the Independent
Underwriter hereunder, as to the Shares to be delivered at each Time of
Delivery, shall be subject, in their discretion, to the condition that all
representations and warranties and other statements of the Company and of the
Selling Stockholders herein are, at and as of such Time of Delivery, true and
correct, the condition that the Company and the Selling Stockholders shall have
performed all of its and their obligations hereunder theretofore to be
performed, the condition (in the case of the Underwriters) that the Independent
Underwriter shall have furnished to the Underwriters the letter referred to in

              (f) On the date of the Prospectus at a time prior to the execution
         of this Agreement, at 9:30 a.m., New York City time, on the effective
         date of any post-effective amendment to the Registration Statement
         filed subsequent to the date of this Agreement and also at each Time of
         Delivery, Arthur Andersen LLP shall have furnished to you a letter or

              (g) (i) Neither the Company nor any of its subsidiaries, on a
         consolidated basis, shall have sustained since the respective dates as

                                       14
<PAGE>   15
         as a whole, otherwise than as set forth or contemplated in the
         Prospectus, the effect of which, in any such case described in clause
         (i) or (ii), is in the judgment of the Representatives so material and
         adverse as to make it impracticable or inadvisable to proceed with the
         public offering or the delivery of the Shares being delivered at such
         Time of Delivery on the terms and in the manner contemplated in the
         Prospectus;

              (h) On or after the date hereof (i) no downgrading shall have
         occurred in the rating accorded the Company's debt securities by any
         "nationally recognized statistical rating organization", as that term
         is defined by the Commission for purposes of Rule 436(g)(2) under the
         Act, and (ii) no such organization shall have publicly announced that
         it has under surveillance or review, with possible negative
         implications, its rating of any of the Company's debt securities;

              (i) On or after the date hereof there shall not have occurred any
         of the following: (i) a suspension or material limitation in trading in
         securities generally on the New York Stock Exchange; (ii) a suspension
         or material limitation in trading in the Company's securities on the
         New York Stock Exchange; (iii) a general moratorium on commercial
         banking activities declared by either Federal or New York State
         authorities; or (iv) the outbreak or escalation of hostilities
         involving the United States or the declaration by the United States of
         a national emergency or war, if the effect of any such event specified
         in this clause (iv) in the judgment of the Representatives makes it
         impracticable or inadvisable to proceed with the public offering or the
         delivery of the Shares being delivered at such Time of Delivery on the
         terms and in the manner contemplated in the Prospectus;

              (j) The Shares to be sold by the Company and the Selling
         Stockholders at such Time of Delivery shall have been duly listed,
         subject to notice of issuance, on the New York Stock Exchange;

              (k) The Company has obtained and delivered to the Underwriters
         executed copies of a lock-up agreement attached hereto as Annex VIII
         from each of the stockholders of the Company listed on Schedule IV
         hereto;

              (l) The Company shall have complied with the provisions of Section
         6(c) hereof with respect to the furnishing of prospectuses on the New
         York Business Day next succeeding the date of this Agreement; and

              (m) The Company and the Selling Stockholders shall have furnished
         or caused to be furnished to you at such Time of Delivery certificates
         of officers of the Company and of the Selling Stockholders,
         respectively, satisfactory to you as to the accuracy of the
         representations and warranties of the Company and the Selling
         Stockholders, respectively, herein at and as of such Time of Delivery,
         as to the performance by the Company and the Selling Stockholders of
         all of their respective obligations hereunder to be performed at or
         prior to such Time of Delivery.

         9.   The Independent Underwriter hereby consents to the references to
it as set forth under the caption "Underwriting" in the Prospectus and in any
amendment or supplement thereto made in accordance with Section 6(a) hereof.

         10.  (a) The Company will indemnify and hold harmless each Underwriter
and each Selling Stockholder, against any losses, claims, damages or
liabilities, joint or several, to which


                                       15
<PAGE>   16
such Underwriter or such Selling Stockholder, as the case may be, may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse each Underwriter and each Selling Stockholder, as the case may be, for
any reasonable legal or other expenses reasonably incurred by such Underwriter
or such Selling Stockholder, as the case may be, in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with either (1) written information furnished to the Company by any
Underwriter through Goldman, Sachs & Co. expressly for use therein, or (2)
written information furnished to the Company by any Selling Stockholder
expressly for use therein. The Company also agrees to indemnify and hold
harmless the Independent Underwriter and each person, if any, who controls the
Independent 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 judgments incurred as a result of the Independent
Underwriter's participation as a "qualified independent underwriter" within the
meaning of Rule 2720 of the National Association of Securities Dealers' Conduct
Rules in connection with the offering of the Stock, except for any losses,
claims, damages, liabilities, and judgments resulting from the Independent
Underwriter's, or such controlling person's, gross negligence or willful
misconduct. Notwithstanding anything contained herein to the contrary, if
indemnity may be sought pursuant to this Section in respect of such action or
proceeding, then in addition to such separate firm for the indemnified parties,
the indemnifying party shall be liable for the reasonable fees and expenses of
not more than one separate firm (in addition to any local counsel) for Morgan
Stanley & Co. Incorporated in its capacity as a "qualified independent
underwriter" and all persons, if any, who control Morgan Stanley & Co.
Incorporated within the meaning of either Section 15 of the Act or Section 20 of
the Exchange Act.

              (b) Each Selling Stockholder, severally but not jointly, will
indemnify and hold harmless each Underwriter and the Company against any losses,
claims, damages or liabilities, joint or several, to which such Underwriter or
the Company, as the case may be, may become subject, under the Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse each Underwriter and
the Company, as the case may be, for any reasonable legal or other expenses
reasonably incurred by such Underwriter or the Company, as the case may be, in
connection with investigating or defending any such action or claim as such
expenses are incurred, in each case to the extent, but only to the extent, that
such untrue statement or allegedly untrue statement or omission or alleged
omission was made in any Preliminary Prospectus, the Registration Statement or
the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by such Selling
Stockholder expressly for use therein. Each Selling Stockholder also agrees,
severally but not jointly, to indemnify and hold harmless the Independent
Underwriter and each person, if any, who controls


                                       16
<PAGE>   17
the Independent 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 judgments incurred as a result of the Independent
Underwriter's participation as a "qualified independent underwriter" within the
meaning of Rule 2720 of the National Association of Securities Dealers' Conduct
Rules in connection with the offering of the Stock, except for any losses,
claims, damages, liabilities, and judgments resulting from Morgan Stanley's, or
such controlling person's, gross negligence or willful misconduct.
Notwithstanding anything contained herein to the contrary, if indemnity may be
sought pursuant to this Section in respect of such action or proceeding, then in
addition to such separate firm for the indemnified parties, the indemnifying
party shall be liable for the reasonable fees and expenses of not more than one
separate firm (in addition to any local counsel) for Morgan Stanley & Co.
Incorporated in its capacity as a "qualified independent underwriter" and all
persons, if any, who control Morgan Stanley & Co. Incorporated within the
meaning of either Section 15 of the Act or Section 20 of the Exchange Act.
Provided, further, however, that the liability of each Selling Stockholder
pursuant to this subsection 10(b) shall not exceed the product of the number of
Shares sold by such Selling Stockholder and the initial public offering price of
the Shares as set forth in the Prospectus.

              (c) Each Underwriter will indemnify and hold harmless the Company,
each Selling Stockholder and the Independent Underwriter, as the case may be,
against any losses, claims, damages or liabilities to which the Company, such
Selling Stockholder or the Independent Underwriter, as the case may be, may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement or the Prospectus or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through Goldman, Sachs
& Co. expressly for use therein; and will reimburse the Company, each Selling
Stockholder and the Independent Underwriter, as the case may be, for any
reasonable legal or other expenses reasonably incurred by the Company, each
Selling Stockholder and the Independent Underwriter, as the case may be, in
connection with investigating or defending any such action or claim as such
expenses are incurred.

              (d) The Independent Underwriter will indemnify and hold harmless
the Company, each Selling Stockholder and each Underwriter against any losses,
claims, damages or liabilities to which the Company, such Selling Stockholder or
such Underwriter, as the case may be, may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, the Registration
Statement or the Prospectus or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by the
Independent Underwriter expressly for use therein or constitutes a reference to
the Independent Underwriter


                                       17
<PAGE>   18
consented to by it pursuant to Section 9 hereof; and will reimburse the Company,
each Selling Stockholder or each Underwriter, as the case may be, for any
reasonable legal or other expenses reasonably incurred by the Company, each
Selling Stockholder or each Underwriter, as the case may be, in connection with
investigating or defending any such action or claim as such expenses are
incurred.

              (e) Promptly after receipt by an indemnified party under
subsection (a), (b), (c) or (d) above of notice of the commencement of any
action, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party under such subsection, notify the
indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party otherwise than under such subsection. In
case any such action shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party (which
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation. No
indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of any indemnified party.

              (f) If the indemnification provided for in this Section 10 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a), (b), (c) or (d) above in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by such indemnifying party(s) on the one hand and the
indemnified party(s) on the other from the offering of the Shares. If, however,
the allocation provided by the immediately preceding sentence is not permitted
by applicable law or if the indemnified party failed to give the notice required
under subsection (e) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of such indemnified party on the one hand and such indemnified party on
the other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative benefits received
by each of the Company, each Selling Stockholder, each Underwriter and the
Independent Underwriter shall be deemed to be in the same proportion as the
total net proceeds from the offering of the Shares purchased under this
Agreement (before deducting expenses) received by the Company and the Selling
Stockholders bear to the total underwriting discounts and commissions received
by the Underwriters with respect to the Shares purchased under this Agreement,
in each case as set forth in the table on the cover page of the Prospectus. The
relative fault shall be determined by


                                       18
<PAGE>   19
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 Company, a Selling Stockholder, an
Underwriter or the Independent Underwriter and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. Each of the Company, each Selling Stockholder, each
Underwriter, and the Independent Underwriter agrees that it would not be just
and equitable if contributions pursuant to this subsection (f) were determined
by pro rata allocation (even if the Underwriters and the Independent Underwriter
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to above in this subsection (f). The amount paid or payable by an indemnified
party as a result of the losses, claims, damages or liabilities (or actions in
respect thereof) referred to above in this subsection (f) shall be deemed to
include any reasonable 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 subsection (f), no Underwriter
nor the Independent Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Shares underwritten
by it and distributed to the public were offered to the public, and the
Independent Underwriter shall not be required to contribute any amount in excess
of the amount by which the total price at which the Shares underwritten by the
Underwriters and distributed to the public were offered to the public exceeds
the amount of any damages which such Underwriter, or Independent Underwriter, as
the case may be, have 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 in this subsection
(f) to contribute are several in proportion to their respective underwriting
obligations and not joint.

              (g) The obligations of the Company and each Selling Stockholder
under this Section 10 shall be in addition to any liability which the Company
and such Selling Stockholder may otherwise have and shall extend, upon the same
terms and conditions, to each person, if any, who controls any Underwriter or
the Independent Underwriter within the meaning of the Act; and the obligations
of the Underwriters under this Section 10 shall be in addition to any liability
which the respective Underwriters may otherwise have and shall extend, upon the
same terms and conditions, to each officer and director of, and to each person,
if any, who controls the Company, any Selling Stockholder or the Independent
Underwriter within the meaning of the Act; and the obligations of the
Independent Underwriter under this Section 10 shall be in addition to any
liability which the Independent Underwriter may otherwise have and shall extend,
upon the same terms and conditions, to each officer and director of, and to each
person, if any, who controls the Company, any Selling Stockholder or any
Underwriter within the meaning of the Act.

         11.  (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within thirty-six hours
after such default by any Underwriter you do not arrange for the purchase of
such Shares, then the Company and the Selling Stockholders shall be entitled to
a further period of thirty-six hours within which to procure another party or
other parties satisfactory to you to purchase such Shares on such terms. In the
event that, within the respective prescribed periods, you notify the Company and
the Selling Stockholders that you have so arranged for the purchase of such
Shares, or the Company and the Selling Stockholders notify you that they have so
arranged for the purchase of such Shares, you or the Company and the Selling


                                       19
<PAGE>   20
Stockholders shall have the right to postpone such Time of Delivery for a period
of not more than seven days, in order to effect whatever changes may thereby be
made necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees to file promptly any
amendments to the Registration Statement or the Prospectus which in your opinion
may thereby be made necessary. The term "Underwriter" as used in this Agreement
shall include any person substituted under this Section with like effect as if
such person had originally been a party to this Agreement with respect to such
Shares.

         (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all of the Shares to be purchased at such Time of
Delivery, then the Company and the Selling Stockholders shall have the right to
require each non-defaulting Underwriter to purchase the number of Shares which
such Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all of the Shares to be purchased at such Time of Delivery,
or if the Company and the Selling Stockholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligations of the
Underwriters to purchase and of the Company to sell the Optional Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter or the Company or the Selling Stockholders, except for the expenses
to be borne by the Company and the Selling Stockholders and the Underwriters as
provided in Section 7 hereof and the indemnity and contribution agreements in
Section 10 hereof; but nothing herein shall relieve a defaulting Underwriter
from liability for its default.

         12.  The respective indemnities, agreements, representations,
warranties and other statements of the Company, the Selling Stockholders and the
several Underwriters and the Independent Underwriter, as 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, the Independent Underwriter or any controlling person of any
Underwriter, the Independent Underwriter or the Company, or any of the Selling
Stockholders, or any officer or director or controlling person of the Company,
or any controlling person of any Selling Stockholder, and shall survive delivery
of and payment for the Shares.

         13.  If this Agreement shall be terminated pursuant to Section 11
hereof, neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter or the Independent Underwriter except as provided
in the second sentence on Section 4(e) hereof and in Sections 7 and 10 hereof;
but, if for any other reason any Shares are not delivered by or on behalf of the
Company and the Selling Stockholders as provided herein, the Company will
reimburse the Underwriters through you for all out-of-pocket expenses approved
in writing by you, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in

Re:      Orion Power Holdings, Inc.

Ladies and Gentlemen:

         We have acted as your special counsel in connection with the sale to
you and the other Underwriters on the date hereof by Orion Power Holdings, Inc.,
a Delaware corporation (the "Company"), and the Selling Stockholders (as defined
below) of [25,000,000] shares (the "Shares") of common stock of the Company, par
value $0.1 per share (the "Common Stock"), pursuant to a registration statement
on Form S-1 under the Securities Act of 1933, as amended (the "Act"), filed with
the Securities and Exchange Commission (the "Commission") on August 18, 2000
(File No. 33-44118), as amended by Amendment No. 1 filed with the Commission on
October 5, 2000, Amendment #2 filed with the Commission on October 26, 2000
[here list any subsequent amendments and filing dates] (collectively) the
"Registration Statement")], a Prospectus dated _________, 2000 [filed with the
Commission pursuant to Rule 424(b) under the Act] (the "Prospectus"), an
underwriting agreement dated _________ 2000 among you as Representatives of the
several Underwriters named in Schedule I to the underwriting agreement, the
selling stockholders named in Schedule II to the underwriting agreement (the
"Selling Stockholders") and the Company (the "Underwriting Agreement"). This
opinion is being rendered to you pursuant to Section 8(a) of the Underwriting
Agreement.

         As such counsel, we have made such legal and factual examinations and
inquiries as we have deemed necessary or appropriate for purposes of this
opinion. In our examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, and the
conformity to authentic original documents of all documents submitted to us as
copies. As to facts material to the opinions, statements and assumptions
expressed herein, we have, with your consent, relied upon oral or written
statements and representations of officers and other representatives of the
Company and others. In addition, we have obtained and relied upon such
certificates and assurances from public officials as we have deemed necessary.

         We are opining herein as to the effect on the subject transaction only
of the federal laws of the United States, the internal laws of the State of New
York and the General

                                      I-1
<PAGE>   32
Corporation Law of the State of Delaware, and we express no opinion with respect
to the applicability thereto, or the effect thereon, of the laws of any other
jurisdiction or, in the case of Delaware, any other laws, or as to any matters
of municipal law or the laws of any local agencies within any state.

         Whenever a statement herein is qualified by "to the best of our
knowledge" or a similar phrase, it is intended to indicate that those attorneys
in this firm who have rendered legal services in connection with the above
transaction do not have current actual knowledge of the inaccuracy of such
statement. However, except as otherwise expressly indicated, we have not
undertaken any independent investigation to determine the accuracy of any such
statement, and no inference that we have any knowledge of any matters pertaining
to such statement should be drawn from our representation of you.

         Capitalized terms used herein without definition have the meanings
assigned to them in the Underwriting Agreement.

         Subject to the foregoing and the other matters set forth herein, it is
our opinion that, as of the date hereof:

         1. The Company has been duly incorporated and is validly existing and
in good standing under the laws of the State of Delaware.

         2. The Underwriting Agreement has been duly authorized, executed and
delivered by the Company.

         3. The Shares to be issued and sold by the Company pursuant to the
Underwriting Agreement have been duly authorized and, when issued to and paid
for by you [and the other Underwriters] in accordance with the terms of the
Underwriting Agreement will be validly issued, fully paid and non-assessable
and, to the best of our knowledge, free of preemptive rights; the Shares to be
sold by the Selling Stockholders pursuant to the Underwriting Agreement have
been duly authorized and validly issued and are fully paid and non-assessable.

         4. The Registration Statement has become effective under the Act and,
to the best of our knowledge, no stop order suspending the effectiveness of the
Registration Statement has been issued under the Act and no proceedings therefor
have been initiated by the Commission [; and any required filing of the
Prospectus pursuant to Rule 424(b) under the Act has been made in accordance
with Rules 424(b) and 430A under the Act].

         5. The Registration Statement and the Prospectus comply as to form in
all material respects with the requirements for registration statements on Form
S-1 under the Act and the rules and regulations of the Commission thereunder; it
being understood, however, that we express no opinion with respect to the
financial statements, schedules or other financial data included in, or omitted
from, the Registration Statement or the Prospectus. In passing upon the
compliance as to form of the Registration Statement and the Prospectus, we have
assumed that the statements made therein are correct and complete.

         In addition, we have participated in conferences with officers and
other representatives of the Company, counsel to the Company, representatives of
the

                                      I-2
<PAGE>   33
independent public accountants for the Company and your representatives, at
which the contents of the Registration Statement and the Prospectus and related
matters were discussed and, although we are not passing upon, and do not assume
any responsibility for, the accuracy, completeness or fairness of the statements
contained in the Registration Statement and the Prospectus and have not made any
independent check or verification thereof, during the course of such
participation, no facts came to our attention that caused us to believe that the
Registration Statement, at the time it became effective, contained an untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
that the Prospectus, as of its date or as of the date hereof, contained or
contains an untrue statement of a material fact or omitted or omits to state a
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading; it being understood
that we express no belief with respect to the financial statements, schedules or
other financial data included in, or omitted from, the Registration Statement or
the Prospectus.

         This opinion is rendered only to you as Representatives of the several
Underwriters under the Underwriting Agreement and is solely for benefit the
benefit of the Underwriters in connection with the transactions covered hereby.
This opinion may not be relied upon by you for any other purpose, or furnished
to, quoted to, or relied upon by any other person, firm or corporation for any
purpose, without our prior written consent.

                                  Very truly yours,

                  FORM OF STROOCK & STROOCK & LAVAN LLP OPINION










_________,  ___, 2000

Goldman, Sachs & Co.
Credit Suisse First Boston Corporation
Deutsche Bank Securities Inc.
Merrill Lynch, Pierce, Fenner & Smith Incorporated
Morgan Stanley & Co. Incorporated
     As representatives of the several Underwriters
         named in Schedule I to the Underwriting Agreement
c/o Goldman, Sachs & Co.
85 Broad Street
New York, NY 10004

Ladies and Gentlemen:

We have acted as counsel to Orion Power Holdings, Inc., a Delaware corporation
(the "Company"), in connection with (i) the Company's Registration Statement on
Form S-1 (Registration No. 333-44118), as amended by Amendments No. 1, 2, __ and
__ (the "Registration Statement"), filed by the Company with the Securities and
___ Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Act"), and (ii) the sale by the Company of an aggregate of _____
shares of common stock, par value $.01 per share (the "Stock"), pursuant to the
Underwriting Agreement, dated as of , 2000 (the "Underwriting Agreement"), by
and among the Company, the selling stockholders named in Schedule II thereto
(the "Selling Stockholders") and you, as representatives of the several
Underwriters named in Schedule I thereto (the "Underwriters").

We are rendering this opinion to you pursuant to Section 8(b) of the
Underwriting Agreement. Capitalized terms used herein and not defined herein
shall have the meanings assigned to such terms in the Underwriting Agreement.

We have examined copies of each of (i) the Underwriting Agreement, (ii) the
Registration Statement and the exhibits thereto, (iii) the Company's Prospectus
dated ______ __, 2000 (the "Prospectus") and (iv) the Certificate of
Incorporation (the "Certificate of Incorporation") and Bylaws (the "Bylaws") of
the Company, as in effect on the date hereof. We have also examined originals or
copies, certified or otherwise identified to our satisfaction, of such corporate
records of the Company, and such documents, records, agreements, instruments

                                      II-1
<PAGE>   35
and certificates of officers and representatives of the Company and others, and
have made such examinations of law, as we have deemed necessary to form the
basis of the opinions hereinafter expressed. In such examinations, we have
assumed the genuineness of all signatures, the authenticity of all documents
submitted to us as originals and the conformity to originals of all documents
submitted to us as copies thereof. As to various questions of fact material to
the opinions expressed below, we have relied upon (i) the representations and
warranties of the Company contained in the Underwriting Agreement or made
pursuant thereto or in connection with the closing thereunder and (ii)
statements by and certificates of officers and representatives of the Company
and others.

Attorneys involved in the preparation of this opinion are admitted to practice
law in the State of New York and we do not purport to express any opinion herein
concerning any law other than the laws of the State of New York, the federal
laws of the United States of America (except for FCC matters as to which we do
not express any opinions), the General Corporation Law of the State of Delaware
and the Delaware Revised Uniform Limited Partnership Act.

For purposes of this letter, we have assumed that the Underwriting Agreement is
a valid and binding obligation of each of you and the other Underwriters and is
enforceable against each of you and the other Underwriters in accordance with
its terms.

When reference is made in this opinion to "our knowledge" or to what is "known
to us," it means, unless otherwise indicated, the actual knowledge attributable
to our representation of the Company of only those partners and associates who
have given substantive attention to the Underwriting Agreement, the Registration
Statement, the Prospectus and the sale of the Shares.

With respect to our opinion expressed in paragraphs 1, 3 and 4 below relating to
the good standing and valid existence of each of the Company and its
subsidiaries, we have relied, with your permission, solely upon good standing
certificates of public officials or upon confirmation via facsimile of good
standing as an existing corporation or partnership from such public officials,
copies of which are being delivered concurrently herewith.

With reference to our opinion in paragraphs 7 and 8 below, our opinion is
limited to (i) review of only those laws and regulation that, in our experience,
are normally applicable to transactions of the type contemplated by the
Underwriting Agreement, and (ii) does not include, and we express no opinion as
to the application of, any federal (including the FCC) or state laws or
regulations regarding the generation, transmission, marketing or sale of
electricity or the ownership or operation of power plants. In addition, we
express no opinion as to the statutes and ordinances, administrative decisions
and rules and regulations of counties, towns, municipalities and special
political subdivisions, or judicial decisions to the extent they deal therewith.

Based upon and subject to the foregoing, we are of the opinion that:

1.   The Company has been duly incorporated and is validly existing as a
     corporation in good standing under the laws of the State of Delaware, with
     corporate power and authority to own its properties and conduct its
     business as described in the Prospectus.

2.   The Company has an authorized capitalization as set forth in the
     Prospectus, and all of the issued shares of capital stock of the Company
     (including the Shares being delivered on the date hereof) have been duly
     and validly authorized and issued and are fully paid and non-assessable;
     and the Shares conform to the description of the Stock contained in the
     Prospectus.

3.   The Company and its subsidiaries have been duly qualified as a foreign
     corporation or limited partnership, as the case may be, for the transaction
     of business and are in good standing under the laws of the jurisdictions
     set forth on Schedule (c).

4.   Each subsidiary of the Company listed on Exhibit 21.1 to the Registration
     Statement is validly existing as a corporation or limited partnership, as
     the case may be, in good standing under the laws of its jurisdiction of
     incorporation or organization with corporate or partnership power and
     authority to own its properties and conduct its business as described in
     the Prospectus.

5.   To our knowledge and other than as set forth in the Prospectus, there are
     no legal or governmental proceedings pending to which the Company or any of
     its subsidiaries is a party or of which any property of the Company or any
     of its subsidiaries is the subject which, if determined adversely to the
     Company or any of its subsidiaries, would individually or in the aggregate
     have a Material Adverse Effect; and, to our knowledge, no such proceedings
     are threatened by governmental authorities or threatened by others against
     the Company or any of its subsidiaries.

6.   The Underwriting Agreement has been duly authorized, executed and delivered
     by the Company.

7.   The issue and sale of the Stock and the compliance by the Company with all
     of the provisions of the Underwriting Agreement and the consummation of the
     transactions therein contemplated will not conflict with or result in a
     material breach or violation of any of the terms or provisions of, or
     constitute a default under the agreements listed on Exhibit 4.1 through
     Exhibit 4.4 or Exhibit 10.1 through Exhibit 10.__ to the Registration
     Statement, which have been identified to us in an officer's certificate as
     being all of the agreements that are material to the Company and its
     subsidiaries taken as a whole, nor will such actions result in any
     violation of the provisions of the Certificate of Incorporation or By-laws
     of the Company, or the Delaware General Corporation Law or any federal or
     New York statute, order, rule or regulation of any court or governmental
     agency or body having jurisdiction over the Company or any of its
     subsidiaries or any of their properties. We express no opinion with respect
     to any such conflict, breach, violation or default not readily
     ascertainable from the face of any such agreement, or arising under or
     based upon any cross-default provisions insofar as it relates to a default
     under an agreement not identified to us, or arising under or based upon any
     covenant of a financial or numerical nature or requiring computation.

8.   No consent, approval, authorization, order, registration, filing or
     qualification of or with any such court or governmental agency or body is
     required under federal or New York law or the Delaware General Corporation
     Law for the issue and sale of the Shares or the consummation by the Company
     of the transactions contemplated by the Underwriting Agreement, except as
     such have been obtained (including the approval by the Federal Energy
     Regulatory Commission), the registration under the Act of the Stock, and
     such consents, approvals, authorizations, registrations or qualifications
     as may be required
<PAGE>   37
     under state securities or Blue Sky laws in connection with the purchase and
     distribution of the Stock by the Underwriters.

9.   The statements set forth in the Prospectus under the caption "Description
     of Capital Stock" insofar as they purport to constitute a summary of
     certain of the terms of the Stock, and under the captions "Risk Factors-We
     have agreed to provide all of the energy required by Duquesne Light Company
     to satisfy its provider of last resort obligation, which could result in
     significant losses to us," "Business" (other than the subheading
     "Regulation") "Certain Relationships and Related Party Transactions,"
     "Description of Indebtedness," "Certain Relationships and Related Party
     Transactions," and "Underwriting" insofar as they purport to describe the
     provisions of the laws and documents referred to therein accurately and
     fairly summarize such terms and such provisions, respectively, in all
     material respects.

10.  The Company is not subject to registration as an "investment company," as
     such term is defined in the Investment Company Act.

11.  The Registration Statement has become effective under the Act and the
     Prospectus was filed pursuant to Rule 424(b) of the rules and regulations
     of the Commission under the Act and, to our knowledge, no stop order
     suspending the effectiveness of the Registration Statement has been issued
     or proceeding for that purpose has been instituted or threatened by the
     Commission.

12.  To our knowledge, there are no contracts or documents of a character
     required by the Act or the rules and regulations thereunder to be described
     in the Registration Statement or the Prospectus or to be filed as exhibits
     to the Registration Statement which are not described or filed as required
     by the Act or the rules and regulations thereunder.

The Registration Statement and the Prospectus and any further amendments and
supplements thereto made by the Company prior to the date hereof (other than the
financial statements and related schedules therein, as to which we express no
opinion) comply as to form in all material respects with the requirements of the
Act and the rules and regulations thereunder; and although we do not assume any
responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus, except for those
referred to in paragraph 9 above, we have no reason to believe that, as of its
effective date, the Registration Statement or any further amendment thereto made
by the Company prior to the date hereof (other than the financial statements and
related schedules therein, as to which we express no opinion) contained an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, not misleading
or that, as of its date, the Prospectus or any further amendment or supplement
thereto made by the Company prior to the date hereof (other than the financial
statements and related schedules therein, as to which we express no opinion)
contained an untrue statement of a material fact or omitted to state a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading or that, as of the date hereof,
either the Registration Statement or the Prospectus or any further amendment or
supplement thereto made by the Company prior to the date hereof (other than the
financial statements and related schedules therein, as to which we express no
opinion) contains an untrue statement of a material fact or omits to state a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

Goldman, Sachs & Co.
Credit Suisse First Boston Corporation
Deutsche Bank Securities Inc.
Merrill Lynch, Pierce, Fenner & Smith Incorporated
Morgan Stanley & Co. Incorporated
    As representatives of the several Underwriters
        named in Schedule I hereto
c/o Goldman, Sachs & Co.
85 Broad Street
New York, NY 10004

Ladies and Gentlemen:

                  We are issuing this opinion letter as special energy
regulatory counsel to Orion Power Holdings, Inc., a Delaware corporation (the
"Company"), in connection with the issuance and sale by the Company of an
aggregate of [       ] shares of Common Stock, par value $.01 per share (the
"Stock"), pursuant to the Underwriting Agreement, dated as of [         ], 2000
(the "Underwriting Agreement"), between the Company and the Underwriters named
in Schedule I thereto (the "Underwriters"). This opinion is being delivered to
you pursuant to Section 8(c) of the Underwriting Agreement.

                  Capitalized terms used herein and not otherwise defined shall
have the meanings assigned to such terms in the Underwriting Agreement, provided
that references to any document means documents in the form executed and
delivered as of the date hereof.

                  The following is based exclusively on specific federal, New
York, Pennsylvania and Ohio energy regulatory statutes and orders, rules or
regulations regarding (a) the generation, transmission, marketing or sale of
electricity or (b) the ownership or operation of power plants. Subject to the
assumptions, qualifications, exclusions and other limitations which are
identified in this letter, we advise you that:

                  (a) The statements in the Prospectus under the captions "Risk
         Factors - Differences in the market and regulatory structures in the
         various regional power markets in which we operate will affect our
         results of operations and profit margin," "Risk Factors - We are
         subject to stringent governmental regulation, which may be burdensome
         or lead to significant costs or liabilities," and "Business -
         Regulation," insofar as such statements purport to describe the laws or
         proceedings referred to therein, are fair and accurate summaries of
         such laws and regulations and such proceedings in all material
         respects. This opinion is based exclusively on specific federal, New
         York, Pennsylvania and Ohio energy regulatory statutes and orders,
         rules or regulations regarding (a) the generation, transmission,
         marketing or sale of electricity or (b) the ownership or operation of
         power plants.

                                     III-1
<PAGE>   42
                  (b) To our knowledge, neither the Company nor any of its
         subsidiaries is (i) subject to regulation as a "holding company" or a
         "subsidiary company" of a holding company or an "affiliate" of a
         subsidiary or holding company or a "public utility company" under
         Section 2(a) of the Public Utility Holding Company Act of 1935, (ii)
         subject to regulation under the Federal Power Act of 1920, as amended,
         other than as contemplated by 18 C.F.R. Section 292.601(c) and other
         than due to its subsidiaries' status as power marketers and owners of
         certain electric transmission facilities subject to the Federal Power
         Act, and its subsidiaries have all exemptions and waivers consistent
         with those granted to entities owning generation with utility
         affiliates and holding market based rates authority, or (iii) subject
         to any state law or regulation with respect to the rates or financial
         or organizational regulation of electric utilities, other than due to
         its subsidiaries' status as "electric corporations" under New York law
         subject to lightened regulation. This opinion is based exclusively on
         specific federal, New York, Pennsylvania and Ohio energy regulatory
         statutes and orders, rules or regulations regarding (a) the generation,
         transmission, marketing or sale of electricity or (b) the ownership or
         operation of power plants.

                  (c) The issue and sale of the Stock and the compliance by the
         Company with all of the provisions of the Underwriting Agreement and
         the consummation of the transactions contemplated therein will not
         result in any violation of any statute or any order, rule or regulation
         of any court or governmental agency or body having jurisdiction over
         the Company or any of its subsidiaries or any of their properties. This
         opinion is based exclusively on specific federal, New York,
         Pennsylvania and Ohio energy regulatory statutes and orders, rules or
         regulations regarding (a) the generation, transmission, marketing or
         sale of electricity or (b) the ownership or operation of power plants.

                  (e) No consent, approval, authorization, order, or
         registration of or with any court or governmental agency or body is
         required for the issue and sale of the Stock or the consummation by the
         Company of the transactions contemplated by the Underwriting Agreement,
         except for consents, approvals, authorizations, orders, or regulations
         associated with the issue and sale of the Stock, which have been
         obtained. This opinion is based exclusively on specific federal, New
         York, Pennsylvania and Ohio energy regulatory statutes and orders,
         rules or regulations regarding (a) the generation, transmission,
         marketing or sale of electricity or (b) the ownership or operation of
         power plants.

         For purposes of this opinion letter, we have relied, without
investigation, upon each of the following assumptions: (i) Each document
submitted to us for review is accurate and complete, each such document that is
an original is authentic, each such document that is a copy conforms to an
authentic original, and all signatures on each such document are genuine; (ii)
there are no agreements or understandings among the parties, written or oral,
and there is no usage of trade or course of prior dealing among the parties that
would, in either case, define, supplement or qualify the terms of the
Underwriting Agreement; (iii) the constitutionality or validity of a relevant
statute, rule, regulation or agency action is not in issue; (iv) all parties to
the Underwriting Agreement will act in accordance with, and will refrain from
taking any action that is forbidden by, the terms and conditions of the
Underwriting Agreement; (v) all agreements other than the Underwriting Agreement
(if any) with respect to which we have provided advice in our letter or reviewed
in connection with our letter would be enforced as written; (vi) the Company and
its subsidiaries will not in the future take any discretionary action (including
a decision not to act) permitted under the Underwriting Agreement that would
result in a violation

                                     III-2
<PAGE>   43
of law or constitute a breach or default under any other agreements or court
orders to which the Company or its subsidiaries may be subject; (vii) except for
those governmental and regulatory approvals that we have specifically opined
upon herein, the Company and its subsidiaries have obtained (and will in the
future obtain) all permits and governmental approvals required, and have taken
(and will in the future take) all actions required, relevant to the consummation
of the transactions or performance of the Underwriting Agreement; and (viii)
each person who has taken any action relevant to any of our opinions in the
capacity of director or officer was duly elected to that director or officer
position and held that position when such action was taken. In addition, we have
relied without any independent verification upon: (i) information contained in
certificates and approvals obtained from governmental authorities; (ii) factual
information contained in applications to governmental authorities, the
Underwriting Agreement; and (iii) factual information we have obtained from such
other sources as we have deemed reasonable. We have assumed without
investigation that there has been no relevant change or development between the
dates as of which the information cited in the preceding sentence was given and
the date of this letter and that the information upon which we have relied is
accurate and does not omit disclosures necessary to prevent such information
from being misleading. For purposes of each opinion, we have relied upon
decisions issued by governmental authorities in each relevant jurisdiction, and
such opinion is not intended to provide any conclusion or assurance beyond that
conveyed by that decision.

         While we have not conducted any independent investigation to determine
facts upon which our opinions are based or to obtain information about which
this letter advises you, we confirm that we do not have any actual knowledge
which has caused us to conclude that our reliance and assumptions cited in the
preceding paragraph are unwarranted or that any information supplied in this
letter is wrong. The term "knowledge" whenever it is used in this letter with
respect to our firm means conscious awareness at the time this letter is
delivered on the date it bears by the following Kirkland & Ellis lawyers who
have reviewed the Underwriting Agreement (herein called "our Designated
Transaction Lawyers"): Mitchell F. Hertz and Katharine M. Costenbader.

         Our advice on every legal issue addressed in this letter is based
exclusively on the specific federal or New York, Pennsylvania and Ohio energy
regulatory statutes and orders, rules or regulations regarding (a) the
generation, transmission, marketing or sale of electricity or (b) the ownership
or operation of power plants. We advise you that issues addressed by this letter
may be governed in whole or in part by other laws, but we express no opinion as
to whether any relevant difference exists between the laws upon which our
opinions are based and any other laws which may actually govern. We also advice
you that we are members of the bars of the District of Columbia and New York
State and are not members of the bars of Pennsylvania or Ohio. We are not
providing this opinion letter except in our capacity as special energy
regulatory legal counsel to the Company on issues relating to the Federal Energy
Regulatory Commission ("FERC"), the New York Public Service Commission
("NYPSC"), the Pennsylvania Public Utilities Commission ("PPUC") and the Public
Utilities Commission of Ohio ("PUCO") and offer no opinions on environmental or
other matters relating to (a) the generation, transmission, marketing or sale of
electricity or (b) the ownership or operation of power plants, whether or not
addressed in the Prospectus or the Underwriting Agreement.

         Our advice on each legal issue addressed in this letter represents our
opinion as to how that issue would be resolved were it to be considered by the
highest court of the jurisdiction upon whose law our opinion on that issue is
based. The manner in which any particular issue would be treated in any actual
court case would depend in part on facts and circumstances

                                     III-3
<PAGE>   44
particular to the case, and this letter is not intended to guarantee the outcome
of any legal dispute which may arise in the future.

         This letter speaks as of the time of its delivery on the date it bears.
We do not assume any obligation to provide you with any subsequent opinion or
advice by reason of any fact about which our Designated Transaction Lawyers did
not have actual knowledge at that time, by reason of any change subsequent to
that time in any law covered by any of our opinions, or for any other reason.

         You may rely upon this letter only for the purpose served by the
provisions in the Underwriting Agreement cited in the initial paragraph of this
letter in response to which it has been delivered. Without our written consent:
(i) no person other than you may rely on this letter for any purpose; (ii) this
letter may not be cited or quoted in any financial statement, prospectus,
private placement memorandum or other similar document; (iii) this letter may
not be cited or quoted in any other document or communication which might
encourage reliance upon this letter by any person or for any purpose excluded by
the restrictions in this paragraph; and (iv) except as required by law, copies
of this letter may not be furnished to anyone (except to the Underwriters) for
purposes of encouraging such reliance; provided that any Person who becomes an
Underwriter on or after the date hereof may rely on this opinion as if it were
addressed to such Person on and as of the Time of Delivery, subject to the
limitations contained in this paragraph.

                                       SINCERELY,



                                       -------------------------------

Ladies and Gentlemen:

         This firm has acted as special environmental counsel to Orion Power
Holdings, Inc., a Delaware corporation (the "Company") on certain limited
matters with regard to the issuance and sale by the Company of Common Stock, par
value $.01 per share (the "Stock") pursuant to the Underwriting Agreement, dated
as of [          ], 2000 (the "Underwriting Agreement") between the Company and
the Underwriters named in Schedule I thereto (the "Underwriters"). This opinion
is being delivered to you pursuant to Section 8(d) of the Underwriting

         Based on and subject to the foregoing, we are of the opinion that the
statements in the Prospectus under the captions "Risk Factors-Environmental

         Schedule I to the Underwriting Agreement
c/o Goldman, Sachs & Co.
85 Broad Street
New York, NY  10004

Ladies and Gentlemen:

         I am Associate General Counsel of Constellation Power Source Holdings,
Inc. and certain of its affiliates, including Constellation Operating Services,
Inc., a Maryland corporation ("COSI"). I and lawyers assisting me have acted as
counsel to COSI, in connection with the sale by COSI of an aggregate of
______shares of common stock, par value $.01 per share of Orion Power Holdings,
Inc. (the "Stock"), pursuant to the Underwriting Agreement, dated as of ______,
2000 (the "Underwriting Agreement"), by and among Orion Power Holdings, Inc.,
the selling stockholders named in Schedule II thereto including COSI (the
"Selling Stockholders") and you, as representatives of the several Underwriters
named in Schedule I thereto (the "Underwriters).

         We are rendering this opinion to you pursuant to Section 8(e) of the
Underwriting Agreement. Capitalized terms used herein and not defined herein
shall have the meanings assigned to such terms in the Underwriting Agreement.

         We have examined copies of each of (i) the Underwriting Agreement, (ii)
the Registration Statement and exhibits thereto, (iii) Orion Power Holding,
Inc.'s Prospectus, and (vi) the Articles of Incorporation (the "Articles of
Incorporation") and Bylaws (the "Bylaws") of COSI, as in effect on the date
hereof. We have also examined originals or copies, certified or otherwise
identified to our satisfaction, of such corporate records of COSI, and such
documents, records, agreements, instruments and certificates of officers and
representatives of COSI and others, and have made such examinations of law, as
we have deemed necessary to form the basis of the opinion hereinafter expressed.
In such examinations, we have assumed the genuineness of all signatures of
parties other than COSI, the authenticity of all documents submitted to us as
originals and the conformity to originals of all documents submitted to us as
copies thereof, in each case as submitted by any person other than COSI. As to
various questions of fact material to the opinions expressed below, we have
relied upon (i) the representations and warranties of COSI contained in the
Underwriting Agreement or made pursuant thereto or in connection with the
closing thereunder and (ii) statements by and certificates of officers and
representatives of COSI and others. In particular, in rendering subparagraph (v)
we have relied upon a certificate of COSI in respect of matters of fact as to
ownership of, and liens,

                                      V-1
<PAGE>   47
encumbrances, equities or claims on the Shares sold by COSI which we believe
that we are justified in relying upon.

         For purposes of this letter, we have assumed that the Underwriting
Agreement is a valid and binding obligation of each of you, the other
Underwriters and Orion Power Holdings, Inc. and is enforceable against each of
you, Orion Power Holdings, Inc. and the other Underwriters in accordance with
its terms.

         When reference is made in this opinion to "our knowledge" or to what is
"known to us," it means, unless otherwise indicated, the actual knowledge
attributable to my representation of COSI and that of in-house attorneys who
have given substantive attention to the Underwriting Agreement and the sale of
the Shares in coordination with me.

         Based on the foregoing, we are of the opinion that:

         (i)      COSI has been duly incorporated and is validly existing and in
                  good standing under the laws of the State of Maryland.

         (ii)     The Underwriting Agreement has been duly authorized, executed
                  and delivered by or on behalf of COSI and the sale of the
                  Shares to be sold by COSI thereunder and the compliance by
                  COSI with all of the provisions of the Underwriting Agreement
                  and the consummation of the transactions therein contemplated
                  will not conflict with or result in any breach or violation of
                  any terms or provisions of, or constitute a default under, any
                  statute, indenture, mortgage, deed of trust, loan agreement or
                  other agreement or instrument known to us to which COSI is a
                  party or by which COSI is bound, or to which any of the
                  property or assets of COSI is subject, nor will such action
                  result in any violation of the provisions of the Articles of
                  Incorporation or By-laws of COSI, or any order, rule or
                  regulation known to us of any court or governmental agency or
                  body having jurisdiction over COSI or the property of COSI;

         (iii)    No consent, approval, authorization or order of any court or
                  governmental agency or body is required under federal or
                  Maryland law for the sale of COSI's Shares contemplated by the
                  Underwriting Agreement. We express no opinion regarding any
                  approval (a) of the FERC under the Federal Power Act with
                  respect to the transactions contemplated by the Underwriting
                  Agreement or (b) required under the Act, state securities laws
                  or Blue Sky Laws;

         (iv)     Immediately prior to the First Time of Delivery COSI had good
                  and valid title to the Shares to be sold at the First Time of
                  Delivery by COSI under the Underwriting Agreement, free and
                  clear of all liens, encumbrances, equities or claims, and full
                  right power and authority to sell, assign, transfer and
                  deliver the Shares to be sold by COSI under the Underwriting
                  Agreement; and

         (v)      Good and valid title to COSI's Shares, free and clear of all
                  liens, encumbrances, equities or claims, has been transferred
                  to each of the several Underwriters, as the case may be, who
                  have purchased such Shares in good faith and without notice of
                  any such lien, encumbrance, equity or claim or any other
                  adverse claim within the meaning of the Uniform Commercial
                  Code.

Ladies and Gentlemen:

         I am Associate General Counsel of Constellation Power Source Holdings,
Inc. a Maryland corporation and certain of its affiliates ("CPS"). I and lawyers
assisting me have acted as counsel to CPS, in connection with the sale by CPS of
an aggregate of ______shares of common stock, par value $.01 per share of Orion
Power Holdings, Inc. (the "Stock"), pursuant to the Underwriting Agreement,
dated as of ______, 2000 (the "Underwriting Agreement"), by and among Orion
Power Holdings, Inc., the selling stockholders named in Schedule II thereto
including CPS (the "Selling Stockholders") and you, as representatives of the
several Underwriters named in Schedule I thereto (the "Underwriters).

         We are rendering this opinion to you pursuant to Section 8(e) of the
Underwriting Agreement. Capitalized terms used herein and not defined herein
shall have the meanings assigned to such terms in the Underwriting Agreement.

         We have examined copies of each of (i) the Underwriting Agreement, (ii)
the Registration Statement and exhibits thereto, (iii) Orion Power Holding,
Inc.'s Prospectus, and (vi) the Articles of Incorporation (the "Articles of
Incorporation") and Bylaws (the "Bylaws") of CPS, as in effect on the date
hereof. We have also examined originals or copies, certified or otherwise
identified to our satisfaction, of such corporate records of CPS, and such
documents, records, agreements, instruments and certificates of officers and
representatives of CPS and others, and have made such examinations of law, as we
have deemed necessary to form the basis of the opinion hereinafter expressed. In
such examinations, we have assumed the genuineness of all signatures of parties
other than CPS, the authenticity of all documents submitted to us as originals
and the conformity to originals of all documents submitted to us as copies
thereof, in each case as submitted by any person other than CPS. As to various
questions of fact material to the opinions expressed below, we have relied upon
(i) the representations and warranties of CPS contained in the Underwriting
Agreement or made pursuant thereto or in connection with the closing thereunder
and (ii) statements by and certificates of officers and representatives of CPS
and others. In particular, in rendering subparagraph (v) we have relied upon a
certificate of CPS in respect of matters of fact as to ownership of, and liens,
encumbrances, equities or claims on the Shares sold by CPS which we believe that
we are justified in relying upon.

         Re:  Orion Power Holdings, Inc. - Lock-Up Agreement

Ladies and Gentlemen:

         The undersigned understands that Goldman, Sachs & Co., Credit Suisse
First Boston Corporation, Deutsche Bank Securities Inc., Merrill Lynch, Pierce,
Fenner & Smith Incorporated and Morgan Stanley & Co. Incorporated, as
representatives (the "Representatives"), propose to enter into an underwriting
agreement (the "Underwriting Agreement") on behalf of the several Underwriters
named in Schedule I to such agreement (collectively, the "Underwriters"), with
Orion Power Holdings, Inc., a Delaware corporation (the "Company"), providing
for a public offering of the Common Stock of the Company (the "Shares") pursuant
to a Registration Statement on Form S-1 to be filed with the Securities and
Exchange Commission (the "SEC").

         In consideration of the agreement by the Underwriters to offer and sell
the Shares, and of other good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the undersigned agrees that, during
the period beginning from the date of the final Prospectus covering the public
offering of the Shares and continuing to and including the date 180 days after
the date of such final Prospectus, the undersigned will not offer, sell,
contract to sell, pledge, grant any option to purchase, make any short sale or
otherwise dispose of any shares of Common Stock of the Company, or any options
or warrants to purchase any shares of Common Stock of the Company, or any
securities convertible into, exchangeable for or that represent the right to
receive shares of Common Stock of the Company, whether now owned or hereinafter
acquired, owned directly by the undersigned (including holding as a custodian)
or with respect to which the undersigned has beneficial ownership within the
rules and regulations of the SEC (collectively the "Undersigned's Shares").

         The foregoing restriction is expressly agreed to preclude the
undersigned from engaging in any hedging or other transaction which is designed
to or which reasonably could be expected to lead to or result in a sale or
disposition of the Undersigned's Shares even if such Shares would be disposed of
by someone other than the undersigned. Such prohibited hedging or other

                                     VIII-1
<PAGE>   54
transactions would include without limitation any short sale or any purchase,
sale or grant of any right (including without limitation any put or call option)
with respect to any of the Undersigned's Shares or with respect to any security
that includes, relates to, or derives any significant part of its value from
such Shares.

         Notwithstanding the foregoing, the undersigned may transfer the
Undersigned's Shares (i) as a bona fide gift or gifts, provided that the donee
or donees thereof agree to be bound in writing by the restrictions set forth
herein, (ii) to any trust for the direct or indirect benefit of the undersigned
or the immediate family of the undersigned, provided that the trustee of the
trust agrees to be bound in writing by the restrictions set forth herein, and
provided further that any such transfer shall not involve a disposition for
value, or (iii) with the prior written consent of Goldman, Sachs & Co. on behalf
of the Underwriters. For purposes of this Lock-Up Agreement, "immediate family"
shall mean any relationship by blood, marriage or adoption, not more remote than
first cousin. In addition, notwithstanding the foregoing, if the undersigned is
a corporation, the corporation may transfer the capital stock of the Company to
any wholly-owned subsidiary of such corporation; provided, however, that in any
such case, it shall be a condition to the transfer that the transferee execute
an agreement stating that the transferee is receiving and holding such capital
stock subject to the provisions of this Agreement and there shall be no further
transfer of such capital stock except in accordance with this Agreement, and
provided further that any such transfer shall not involve a disposition for
value. The undersigned now has, and, except as contemplated by clause (i), (ii),
or (iii) above, for the duration of this Lock-Up Agreement will have, good and
marketable title to the Undersigned's Shares, free and clear of all liens,
encumbrances, and claims whatsoever. The undersigned also agrees and consents to
the entry of stop transfer instructions with the Company's transfer agent and
registrar against the transfer of the Undersigned's Shares except in compliance
with the foregoing restrictions.

         The undersigned understands that the Company and the Underwriters are
relying upon this Lock-Up Agreement in proceeding toward consummation of the
offering. The undersigned further understands that this Lock-Up Agreement is
irrevocable and shall be binding upon the undersigned's heirs, legal
representatives, successors, and assigns.
