     1.   Background.
          ----------

     (a)  Pursuant to the request of the Borrower, the Issuer has agreed to
finance costs of the acquisition, construction, renovation, equipping and

powers systems, power distribution equipment and systems integration equipment
and services (the "Project"), through the issuance and sale of $6,500,000
aggregate principal amount of its Adjustable Rate Demand Industrial Development
Revenue Bonds, Series 2001 (PECO II, Inc. Project) (the "Series 2001 Bonds"),
consisting of $2,000,000 Series 2001A Bonds (the "Series 2001A Bonds") and
$4,500,000 Series 2001B Bonds (the "Series 2001B Bonds").

     (b)  The Series 2001 Bonds will be issued pursuant to a resolution (the
"Resolution") adopted on July 31, 2001, by the Board of County Commissioners of
the Issuer, and will be secured under a Trust Indenture (the "Indenture"), dated
as of August 1, 2001, between the Issuer and The Huntington National Bank, as
trustee (the "Trustee") for the holders of the Series 2001 Bonds.  The Series
2001 Bonds will be payable from the Revenues, as defined in the Indenture,
including the Project Notes (the "Notes"), as defined in a Loan Agreement (the
"Agreement"), dated as of  August 1, 2001, between the Issuer and the Borrower,
pursuant to which the Issuer will make the proceeds of the Series 2001 Bonds
available to the Borrower for the purposes therein described.  The Series 2001
Bonds will also be secured by an assignment pursuant to the Indenture of certain
of the Issuer's rights under the Agreement.  The principal of and up to 45 days'
interest on, and certain purchase price payments relating to, the Series 2001
Bonds will also be secured by irrevocable Letters of Credit (the "Letters of
Credit"), each relating to a separate series of the Series 2001 Bonds, dated the
date of initial delivery of the Series 2001 Bonds, issued by the Letter of
Credit Bank in favor of the Trustee.  Pursuant to a Reimbursement Agreement (the
"Letter of Credit Agreement") dated as of August 1, 2001 between the Borrower
and the Letter of Credit Bank, the Borrower will agree to reimburse the Letter
of Credit Bank for amounts drawn on the Letters of Credit.

     The Borrower's obligations under the Letter of Credit Agreement will be
secured by a Security Agreement (Equipment, Fixtures, Inventory, and
Receivables) and a Deed of Trust, Assignment of Rents, and Security Agreement,
each dated as of August 1, 2001 (collectively, the "Security Documents") between
the Borrower and the Bank. The Borrower has executed and delivered to the Letter
of Credit Bank financing statements on Form UCC-1's (the "Financing
Statements").

     Pursuant to the Indenture, Bondholders initially will have certain options
to tender Series 2001 Bonds for purchase, which tendered Series 2001 Bonds will
be purchased with funds drawn on the Letters of Credit, subject to subsequent
remarketing as provided in the Indenture.

     (c)  It is intended that the Project will conform with the provisions of
the County and Municipality Development Revenue Bond Act, Section 29-3-101 et
seq., Colorado Revised Statutes (the "Act") and that the proceeds of the Series

from and after a Tax Exempt Conversion Date, as defined in the Indenture, the
interest on the converted Series 2001B Bonds (the "Segregated Series 2001B
Bonds"), will be excludible from gross income for Federal income tax purposes,
and that the Series 2001 Bonds may be purchased by the Underwriter without
registration of any security under the Securities Act of 1933 (the "Securities
Act") or qualification of any indenture under the Trust Indenture Act of 1939
(the "Trust Indenture Act"). In order that interest on the Series 2001A Bonds
shall be and remain excludible from gross income for federal income tax purposes
from and after the Closing, the Issuer, the Trustee and the Borrower will enter
into a Tax Regulatory Agreement for the Series 2001A Bonds (the "Tax Regulatory
Agreement"), dated as of August 1, 2001.

     (d)  In order to induce the Issuer and the Underwriter to enter into this
Bond Purchase Agreement, to induce the Issuer to issue and deliver the Series
2001 Bonds, and to induce the Underwriter to purchase the Series 2001 Bonds, the
Borrower and the Letter of Credit Bank have joined in this Bond Purchase
Agreement.

     (e)  Subject to the provisions of the Agreement and the Indenture, the
proceeds of the sale of the Series 2001 Bonds are to be made available to the
Borrower to provide a portion of the funds necessary to pay the cost of the
acquisition, construction, renovation, equipping and installation of the Project
by the Borrower, and to pay certain expenses related to the issuance of the
Series 2001 Bonds, including, but not limited to, the costs of preparing and
reproducing or printing the Indenture, the Agreement, the Tax Regulatory
Agreement, the Security Documents, the Letters of Credit, the Letter of Credit

          material respects to the forms of the drafts thereof delivered to the

     (b)  Between the date hereof and the Closing, legislation shall not have
been enacted by the Congress or be actively considered for enactment by
Congress, or recommended to the Congress for passage by the President of the
United States, or introduced or favorably reported for passage to either house
of the Congress, and neither a decision, order or decree of a court of competent
jurisdiction, nor an order, ruling, regulation or official statement of or on
behalf of the Securities and Exchange Commission shall have been rendered or
made, with the purpose or effect that the issuance, offering or sale of the
Series 2001 Bonds or any related security or obligations of the general
character of the Series 2001 Bonds or any related security as contemplated
hereby, or the execution and delivery of the Indenture or indentures similar
thereto, is or would be in violation of any provision of, or is or would be
subject to registration or qualification requirements under, the Securities Act

respect to the extension of credit by, or change in the net capital requirements
of, underwriters; (iii) the Treasury Department of the United States or the
Internal Revenue Service shall issue an order, ruling or regulation, in each
such case with the purpose or effect, directly or indirectly, of including the
interest that would be received by the holders of the Series 2001A Bonds or
Segregated Series 2001B Bonds in gross income of such holders for income tax
purposes or subjecting to federal income taxation the proceeds that would be
recovered by the

Issuer under the Agreement; (iv) a general banking moratorium shall have been
declared by Federal, New York, Colorado or Ohio authorities; or (v) a war
involving the United States of America, whether or not declared, or any other
national or international calamity or crisis, or a financial crisis, shall have

impracticable to market the Series 2001 Bonds or would materially and adversely
affect the ability of the Underwriter to enforce contracts for the sale of the
Series 2001 Bonds.

     (e)  All matters relating to this Bond Purchase Agreement, the Series 2001

amounts in connection with the transactions contemplated hereby other than from

<PAGE>

Series 2001 Bonds are not delivered to the Underwriter (other than because of a
default by the Underwriter) as herein provided, all such expenses, except as

connection with the transactions contemplated by this Bond Purchase Agreement.

          Demand Industrial Development Revenue Bonds, Series 2001 (PECO
          II, Inc. Project)

Ladies and Gentlemen:

          This opinion is being rendered to you pursuant to your respective
requests to us as counsel for PECO II, Inc. (the "Borrower"), pursuant to
Section 9(a)(i) of the Bond Purchase Agreement dated August 8, 2001 (the "Bond
Purchase Agreement"), among County of Arapahoe, Colorado (the "Issuer"), the
Borrower, The Huntington National Bank, a national banking association, as
provider of the letters of credit (the "Bank") and Huntington Capital Corp., as
Underwriter (the "Underwriter"), and pursuant to Section 5.1.1 of the
Reimbursement

                                       1
<PAGE>

Agreement dated as of August 1, 2001 (the "Letter of Credit Agreement") between
the Borrower and the Bank, all relating to the issuance and sale by the Issuer
of the above-captioned bonds (the "Series 2001 Bonds"). We have examined
executed copies of the Loan Agreement dated as of August 1, 2001 (the
"Agreement"), between the Issuer and the Borrower relating to the Series 2001
Bonds, the Indenture, the Notes, the Bond Purchase Agreement, the Offering
Memorandum, the Tax Regulatory Agreement, the Security Documents, the Financing
Statements and the Remarketing Agreement, each as defined in the Bond Purchase
Agreement (such documents, other than the Indenture and the Offering Memorandum,
collectively referred to as the "Financing Documents"), relating to the Bonds.
We have also examined the original, photostatic or certified copies of the
Borrower's Articles of Incorporation, Code of Regulations, resolution of its
Board of Directors and such other records of the Borrower and other documents
and materials, and have made such inquiries, as we have deemed relevant and
necessary.

          We have assumed the genuineness of all signatures, other than those of
the Borrower, and the authenticity of all documents submitted to me as originals
and as certified, conformed or photostatic copies. In addition, we have relied
as to factual matters, without an independent investigation, on certificates or
other comparable documents of officers of the Borrower and on the
representations and warranties of the Borrower contained in the Agreement, the
Letter of Credit Agreement, the Security Documents and the Bond Purchase
Agreement. We have further assumed that each of the foregoing documents have
been duly authorized, executed and delivered by and on behalf of each party
thereto, other than the Borrower.

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

          1.   The Borrower is an Ohio corporation duly organized, validly
existing and in good standing under the laws of the State of Ohio, duly licensed
to do business as a foreign corporation under the laws of the State of Colorado,
is not in violation of any provision of its Articles of Incorporation, Code of
Regulations, or any resolution of its shareholders, Board of Directors, or any
committee thereof, has full power and authority to conduct the business now
being conducted by the Borrower and proposed to be conducted by the Borrower
with respect to the Project, as defined in the Agreement, and has full power and
authority to execute and deliver and carry out and perform the Borrower's
obligations under the Financing Documents.

          2.   The Financing Documents have been duly authorized, executed and
delivered by the Borrower and are valid, binding and legally enforceable
obligations of the Borrower in accordance with their respective terms, except as
the enforceability of the same may be subject to bankruptcy, insolvency,
reorganization, moratorium and other laws in effect from time to time affecting
creditors' rights, and to the exercise of judicial discretion in accordance with
general principles of equity. The Borrower has duly taken any and all action
necessary to carry out and give effect to the transactions contemplated to be
performed on the Borrower's part by the Financing Documents.

          3.   The execution and delivery of the Financing Documents, the
performance by the Borrower of the Borrower's obligations thereunder, and the
present conduct of business by the Borrower do not and will not conflict with,
violate or constitute a default under the Borrower's Articles of Incorporation,
Code of Regulations, or any resolution of its shareholders,

                                       2
<PAGE>

Board of Directors, or any committee thereof, or any court or administrative
order, decree or ruling, or any law, statute, ordinance or regulation, or any
agreement, indenture, mortgage, lease, note or other obligation or instrument,
binding upon the Borrower or any of the Borrower's properties or assets, and no
approval or other action by any governmental authority or agency is required in
connection therewith except such approvals and actions as have already been
obtained or taken.

          4.   Other than as disclosed to the addressees hereto there is no
action, suit, proceeding, inquiry or investigation at law or in equity before or
by any judicial or administrative court, board or agency, pending or threatened
against or affecting the Borrower, or any of the Borrower's properties,
businesses or securities, or any basis for any such action, suit, proceeding,
inquiry or investigation, wherein an unfavorable decision, ruling or finding
would materially and adversely affect the Project or the delivery, validity or
enforceability of the Financing Documents, or the consummation of the
transactions contemplated thereby, or which would have a material and adverse
effect on the business, assets or financial condition of the Borrower.

          5.   Other than as disclosed to the addressees hereof, the
acquisition, construction, renovation, equipping, installation and operation of
the Project, as contemplated, in the Agreement, does not conflict with or is in
violation of any applicable zoning or other land use law, rule, regulation or
ordinance as in effect on the date hereof.

          6.   We have no reason to believe that any representation or warranty
made by the Borrower in the Financing Documents, or any certificate delivered by
the Borrower or any of its officers, at the closing of the sale of the Series
2001 Bonds to the Underwriter, is untrue or incorrect in any material respect or
omits to state a material fact necessary to make such representation or warranty
not misleading.

          7.   To the best of our knowledge, the statements and information
relating to the Borrower and the Project in the Offering Memorandum are accurate
in all material respects and do not contain any untrue statement of material
fact or omit to state any material fact required to be stated therein or
necessary in order to make such statements and information therein not
misleading.

          8.   The Bank has been, pursuant to the Security Documents and
accompanying financing statements, granted a valid and enforceable first deed of
trust lien on and security interest in the Project, free and clear of all liens
and claims. No financing statement covering the Project or any part thereof is
on file in any public office.

            [Reliance or reference to Borrower's Colorado counsel]

                  Very truly yours,

The Huntington National Bank, as Trustee
Columbus, Ohio

     RE:  $6,500,000 County of Arapahoe, Colorado Adjustable Rate Demand
          Industrial Development Revenue Bonds, Series 2001 (PECO II, Inc.
          Project)

Ladies and Gentlemen:

     We have acted as Bond Counsel to County of Arapahoe, Colorado (the
"Issuer") in connection with the issuance of its $6,500,000 Adjustable Rate
Demand Industrial Development Revenue Bonds, Series 2001 (PECO II, Inc.
Project). In connection with the issuance of the Bonds, The Huntington National
Bank (the "Bank") will issue irrevocable Letters of Credit dated August 8, 2001
(the "Letters of Credit") to The Huntington National Bank, as Trustee
("Trustee"), for the benefit of the Bondholders covering the payment of the
principal of and interest on the Bonds.

     In rendering this opinion, we have examined executed counterparts of the
Reimbursement Agreement dated as of August 1, 2001, between the Bank and PECO
II, Inc. (the "Borrower"); the Letters of Credit; the Trust Indenture dated as
of August 1, 2001 (the "Indenture") between the Issuer and the Trustee; the Bond
Purchase Agreement (the "Purchase Agreement") dated August 8, 2001, among
Huntington Capital Corp., as Underwriter, the Bank, the Borrower and the Issuer
(collectively the "Financing Documents"); and such other documents as we deemed
necessary for purposes of this opinion.

     In rendering this opinion, we have assumed the genuineness of all
signatures, other than the Issuer, the authenticity of all documents submitted
to us as originals, the conformity to original documents of all documents
submitted to us as certified or photostatic copies and the authenticity of the
originals of such copies, which assumptions we have not independently verified.
We have also assumed that the Financing Documents: (i) were duly authorized,
executed and delivered by the parties thereto, other than the Issuer; (ii) are
the legal, valid and binding obligations of the parties thereto, other than the
Issuer; and (iii) have not been modified or amended. As to questions of fact
material to this opinion, we have relied upon the representations and warranties
contained in the Financing Documents, and on certificates of officers or
representatives of the Bank, the Borrower the Issuer and the Trustee. We have
also relied for purposes of this opinion on the opinions of Porter, Wright,
Morris & Arthur, LLP, as counsel to the Bank, and of Hottenroth, Garverick &
Tilson Co., L.P.A., and

                                       1
<PAGE>

________________as counsel to the Borrower, of even date herewith issued in
connection with the referenced transaction.

     We have considered the foregoing in light of the United States Bankruptcy
Code as presently in effect, 11 U.S.C. (S)101 et seq. (the "Bankruptcy Code"),
                                              -- ---
and the effect of the filing of a petition in bankruptcy by or against the
Borrower. For purposes of this opinion, we have assumed that: (a) no Bondholder
or any subsequent registered owner, transferee or assignee of the Bonds is an
affiliate of the Borrower, (b) any trustee or debtor-in-possession in any
bankruptcy proceeding involving the Borrower could only avoid those preferential
transfers made within the 91-day period immediately prior to the date of the
filing of the petition initiating that bankruptcy proceeding, (c) the terms and
provisions of the Bonds and the Indenture, including without limitation those
provisions of the Indenture requiring the Trustee to draw under the Letters of
Credit and to hold monies received from drawings under the Letters of Credit, or
from the Borrower for the payment of redemption premium on the Bonds, or from
subsequent purchasers of the Bonds upon a remarketing of the Bonds, in
segregated accounts and not commingled with each other or with other monies, and
to hold monies in segregated accounts for specified periods of time, are fully
and timely complied with as currently written, (d) the payment of the purchase
price for the Bonds by the Bondholders, the issuance of the Bonds, the issuance
of the Letters of Credit, the execution and delivery of the other Financing
Documents, and the granting of a mortgage and other security interests by the
Borrower to secure its obligations under the Letters of Credit and the
Reimbursement Agreement were intended to be and, in fact, were contemporaneous,
(e) no Bondholder or any subsequent registered owner, transferee or assignee of
the Bonds is an "insider" of the Borrower or the Issuer, as that term is defined
in (S)101(30) of the Bankruptcy Code, (f) no additional security will be granted
to or for the benefit of the Trustee or the Bondholders to secure the
performance of the Borrower's obligations under the Bonds or the Financing
Documents, and (g) all remarketings of the Bonds will be done in strict
compliance with the terms of the Indenture as currently written.

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

     1.   Payments of principal and interest on the Bonds made by the Trustee to
the Bondholders from the drawings under the Letters of Credit, will not
constitute voidable preferences under Section 547 of the Bankruptcy Code or
voidable transfers under Section 549 of the Bankruptcy Code in the event a
petition in bankruptcy is filed by or against the Borrower.

     2.   Payments of the purchase price of Bonds made by the Trustee to the
Bondholders upon a tender or redemption of the Bonds from drawings under the
Letters of Credit or from monies received by the Trustee from the purchaser of
such Bonds in connection with the remarketing of such Bonds, will not constitute
voidable preferences under Section 547 of the Bankruptcy Code or voidable
transfers under Section 549 of the Bankruptcy Code in the event a petition in
bankruptcy is filed by or against the Borrower.

     3.   Payments of a redemption premium, if any, on the Bonds made by the
Trustee to the Bondholders from Eligible Funds will not constitute voidable
preferences under Section 547 of the Bankruptcy Code or voidable transfers under
Section 549 of the Bankruptcy Code in the event a petition in bankruptcy is
filed by or against the Borrower.

     RE:  $6,500,000 County of Arapahoe, Colorado Adjustable Rate Demand
          Industrial Development Revenue Bonds, Series 2001 (PECO II, Inc.
          Project)

Ladies and Gentlemen:

     We have acted as counsel for The Huntington National Bank (the "Bank") in
connection with the issuance by the Bank of two irrevocable letters of credit
(the "Letters of Credit") relating to the issuance of the referenced Bonds.

     This opinion is being rendered pursuant to Section 9(a)(i) of the Bond
Purchase Agreement (the "Bond Purchase Agreement"), dated August 1, 2001, among
PECO II, Inc. (the "Borrower"), the Bank, County of Arapahoe, Colorado (the
"Issuer") and Huntington Capital Corp., as Underwriter, relating to the issuance
and sale of $6,500,000 County of Arapahoe, Colorado Adjustable Rate Demand
Industrial Development Revenue Bonds, Series 2001 (PECO II, Inc. Project) (the
"Bonds") as of the date hereof.  Terms defined in the Bond Purchase Agreement
are used in this opinion with the meanings assigned to them in the Bond Purchase
Agreement.

 We have examined or reviewed the following:

               A.   Executed counterparts of the Letters of Credit, the Letter
                    of Credit Agreement and the Bond Purchase Agreement.

               B.   Applicable provisions of the laws of the United States of
                    America and the State of Ohio.

                                       1
<PAGE>

               C.   Certificates of public officials and of officers of the
                    Bank, and such other documents and information as we have
                    considered relevant and necessary to enable us to render
                    this opinion.

     We have assumed the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to us
as certified or photostatic copies, the authenticity of the originals of such
latter documents and the accuracy of the statements contained in such
certificates. We have also assumed the due authorization, execution and delivery
of the parties thereto, other than the Bank, of the documents herein referred
to.

     To render this opinion, we have relied as to factual matters on the
representations, warranties and other statements made in the foregoing documents
or in connection therewith.

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

     1.   The Bank is a national banking association duly organized and validly
existing under the laws of the United States of America.

     2.   The Bank has all necessary national banking association power and
authority to (a) issue the Letters of Credit, and (b) execute and deliver, and
perform its obligations under, the Letters of Credit, the Bond Purchase
Agreement and the Letter of Credit Agreement and enter into and carry out the
transactions contemplated on the Bank's part by such documents.

     3.   The Letters of Credit have been duly issued, executed and delivered by
the Bank, the Bond Purchase Agreement and the Letter of Credit Agreement have
each been duly authorized, executed and delivered by the Bank and the Letters of
Credit, the Bond Purchase Agreement and the Letter of Credit Agreement are
legal, valid and binding obligations of the Bank, enforceable in accordance with
their respective terms, except that the binding effect and the enforceability
thereof are subject to application of insolvency, reorganization, moratorium and
other laws in effect from time to time affecting the rights of creditors
generally, as such laws may be applied in the event of a bankruptcy, insolvency,
reorganization or other similar proceeding of, or moratorium applicable to, the
Bank and to the application of general principles of equity and public policy.

     4.   The issuance, execution and delivery of, and performance of its
obligations under, the Letters of Credit, the execution and delivery of the Bond
Purchase Agreement and the Letter of Credit Agreement and the performance by the
Bank of the actions required of it by those documents and the consummation of
the transactions contemplated on the Bank's part in those documents, do not
violate any provisions of the Bank's Articles of Association or Bylaws as
amended to date, or, to our knowledge without independent inquiry, do not
violate any indenture, mortgage, deed of trust, guaranty, lease, agreement or
other instrument to which the Bank is a party or by which it or any of its
property or assets is bound, and do not, and will not, to our knowledge without
independent inquiry, conflict with or violate any provisions of any law,

                                       2
<PAGE>

administrative rule or regulation or, to our knowledge without independent
inquiry, any judgment, order or decree to which the Bank or any of its property
or assets is subject.

     5.   To our knowledge without independent inquiry, there is no claim,
action, temporary restraining order, injunction, suit, proceeding, inquiry or
investigation, at law or in equity, or before or by any judicial or
administrative court, governmental agency, public board or body, pending or
threatened against or affecting the Bank (i) contesting the existence or powers
of the Bank or the titles of its respective officers to their respective
offices, or (ii) seeking to prohibit, restrain or enjoin the issuance of the
Letters of Credit, or (iii) challenging the validity or enforceability of the
Letters of Credit, the Bond Purchase Agreement or the Letter of Credit Agreement
or contesting the power and authority of the Bank to execute and deliver or to
consummate the transactions contemplated on the Bank's part in such documents,
or (iv) wherein an unfavorable decision, ruling or finding would in any way
adversely affect the validity or enforceability of the Letters of Credit, the
Bond Purchase Agreement or the Letter of Credit Agreement (or any other
instrument required or contemplated for use in consummating the transactions
contemplated on the Bank's part thereby) or the transactions contemplated by
such documents.

     6.   No approval, permit, consent, authorization or order of any court or
any governmental or public agency or authority in the State of Ohio or of the
United States of America not already obtained or effected is required with
respect to the Bank in connection with the issuance, execution and delivery by
the Bank of, or the performance by the Bank of its obligations under, the Bond
Purchase Agreement and the Letter of Credit Agreement.

     7.   We have also examined the portions of the Offering Memorandum dated
August 8, 2001 relating to the issuance of the Bonds pertaining to the Letters
of Credit as described in Parts I and IV therein and nothing has come to our
attention which causes us to believe that such portions of the Offering
Memorandum are not accurate in all material respects or that they contain any
untrue statement of material fact or omit to state any material fact necessary
to make the statements made therein, in light of the circumstances under which
they were made, not misleading.

     The foregoing opinions are limited to the laws of the State of Ohio and the
Federal laws of the United States of America; provided that, in giving the
opinions in paragraph 3, 4 and 6, above, we have not considered, nor are we
rendering any opinion with respect to, the securities laws of the United States
of America or of any State or other jurisdiction.

     This letter is intended for the information solely of the parties to whom
it is addressed and is not to be quoted in whole or part or otherwise referred
to in any document or to be filed with any governmental or other administrative
agency or other person for any purpose without the prior written consent of the
undersigned. We bring to your attention the fact that our legal opinions are an
expression of judgment and not a guaranty of a result.

     We have assumed and the opinions expressed herein concern only the effects
of such laws (excluding the principles of conflicts of laws) as are currently in
effect and published decisions of the Ohio and federal courts, notwithstanding
that the provisions of certain of the

                                       3
<PAGE>

transaction documents contain choice of law provisions for such documents to be
governed and construed by the laws of another state. Our opinion is based on the
assumption that the internal laws of any other state would, in all relevant
respects, be identical to those of the State of Ohio.

                                        Very truly yours,

                                       4

                                  APPENDIX E

                      [Opinion of Counsel to the Issuer]


                               [Date of Issuance]

County of Arapahoe, Colorado
Littleton, Colorado

Peck, Shaffer & Williams LLP
Columbus, Ohio

The Huntington National Bank, as Trustee
Columbus, Ohio

     Re:  $6,500,000 County of Arapahoe, Colorado Adjustable Rate Demand
          Industrial Development Revenue Bonds, Series 2001 (PECO II, Inc.
          Project) consisting of $2,000,000 Series 2001A Bonds and $4,500,000
          Series 2001B Bonds

     We have acted as counsel to the County of Arapahoe, Colorado (the "Issuer")
in connection with the issue of the bonds described above (the "Bonds") by the
Issuer pursuant to the Loan Agreement dated as of August 1, 2001 (the "Loan
Agreement") between the Issuer  and PECO, II, Inc. (the "Company") and the Trust
Indenture dated as of August 1, 2001 (the "Indenture") between the Issuer and
The Huntington National Bank, as Trustee.  In connection with the issue of the
Series 2001A Bonds, the Issuer has entered into a Tax Regulatory Agreement dated
as of August 1, 2001 (the "Tax Agreement") with the Company and the Trustee.
The Bonds are being sold pursuant to a Bond Purchase Agreement (the "Bond
Purchase Agreement") among the Issuer, the Company, The Huntington National Bank
as issuer of letters of credit, and Huntington Capital Corp., as underwriter.
The Loan Agreement, Indenture, Tax Agreement and Bond Purchase Agreement are
referred to collectively herein as the "Bond Documents".

     As to questions of fact material to our opinion we have relied upon
representations and covenants of the Issuer and the Company contained in the
Bond Documents, the certified proceedings and other certifications of public
officials furnished to us, and certifications by officials of the Company and
others, without undertaking to verify the same by independent investigation.

     We express no opinion with respect to compliance by the Company with
applicable legal requirements in connection with the acquisition, renovation,
equipping, leasing or operation of the Project to be financed by the Agreement.

     We have made such examination as we have deemed necessary to render this
opinion.  Based on the foregoing, we are of opinion that:

                                       5
<PAGE>

     1.   The Issuer is a county and political subdivision duly organized and
existing under the laws of the State of Colorado with the authority to incur and
perform its obligations under the Bond Documents and to issue the Bonds.

     2.   The Bond Documents and the Bonds have been duly authorized, executed
and delivered by the Issuer pursuant to a resolution of the Issuer's Board of
County Commissioners which was duly adopted on July 31, 2001.

     3.   To the best of our knowledge after due inquiry, but without
independent investigation, there is no action, suit, proceeding or investigation
at law or in equity before or by any court, either state or federal, or public
board or body, pending or threatened, calling into question the existence or
operations of the Issuer, the validity of the Bond Documents or the Bonds or the
authority of the Issuer to enter into the Bond Documents or to issue the Bonds.

     4.   To the best of our knowledge after due inquiry, but without
independent investigation, the authorization, execution and delivery by the
Issuer of the Bond Documents and the issuance by the Issuer of the Bonds will
not violate any existing decree, writ or injunction and will not contravene the
provisions of, constitute a default under, or result in the creation of a lien,
charge or encumbrance prohibited by, any existing agreement, indenture, bond
resolution or other instrument to which the Issuer is a party or by which the
Issuer or any of its assets is bound.


                              Very truly yours.
