          (iv) all of the Seller's interest in and claims and rights under
     contracts and other agreements, Permits (as hereinafter defined), titles,

     applications therefor which are referred to in this Agreement or any

     specifically referred to in this Agreement. In confirmation of the
     foregoing sale, assignment and transfer, the Seller shall execute and

corporation duly organized, validly existing and in good standing
under the laws of the State of Maine and has the corporate power and
lawful authority to own, lease and operate its assets and properties
and to carry on its business as now conducted. The Seller is qualified
to transact business and is in good standing in each jurisdiction in
which the nature of its business or location of its properties
requires such qualification and in which the failure so to qualify
could have a material adverse effect on the Seller or its assets,
properties or business. The Seller does not own or lease property in
any jurisdiction other than its jurisdiction of incorporation and the
jurisdictions set

                                      - 4 -

forth on Schedule 5.1, and is not required to be qualified or
otherwise authorized to do business in any other jurisdiction.

     5.2 Subsidiaries. The Seller does not, directly or indirectly,
own or have the power to vote, or to exercise a controlling influence
with respect to, 50% or more of the securities of any class of any
person the holders of which class are entitled to vote for the
election of directors (or persons performing similar functions) of
such person, and except as so set forth, the Seller is not an
affiliate of any person engaged in the same business as the Seller or
any business related to the business of the Seller.

     5.3 Certificate of Incorporation and By-laws. The copies of the
Certificate of Incorporation and By-laws of the Seller, and all
amendments to each, which have been delivered to the Buyer are true
and complete copies of the originals thereof.

     5.4 Financial Statements. The balance sheets of the Seller as at
December 31, 1994, December 31, 1995, December 31, 1996 and April 30,
1997, and the related statements of income, retained earnings and
changes in financial position for the fiscal periods then ended,
including the footnotes thereto, which have been delivered to the
Buyer, fairly present the financial position of the Company as at such
dates and the results of its operations and the changes in its
retained earnings and its financial position for the periods then
ended in accordance with generally accepted accounting principles
consistently applied. (The foregoing financial statements of the
Seller as at April 30, 1997 and for the period then ended being
sometimes herein called the "Financials," the balance sheet included
in the Financials being sometimes herein called the "Balance Sheet,"
and April 30, 1997 being sometimes herein called the "Balance Sheet

     5.5 No Material Adverse Change. Since the Balance Sheet Date,
there has been no material adverse change in the assets, properties,
business or condition, financial or otherwise, of the Seller, and

assessments of tax, interest or penalties owed by it. Neither the
Seller nor either Principal knows of any unassessed tax deficiency
proposed or threatened against the Seller. Except as set forth on
Schedule 5.6, no audit of any tax return of the Seller is in progress
and no extensions of time with respect to any date on which any tax
return was or is to be filed by the Seller is in force, and no waiver
or agreement by the Seller is in force for the extension of time for
the assessment or payment of any tax.

     5.7 Compliance with Laws. The Seller has complied with all
federal, state, county, local and foreign laws, ordinances,
regulations and orders applicable to it or its business. Except as set

threatened against or involving the Seller, and (vi) no grievance that

instrument, contract or other agreement to which the Seller or a

connection with the deposit of items for collection; (x) any other
material contract or other agreement whether or not made in the
ordinary course of business (other than those reflected on Schedules

other agreements set forth on Schedule 5.11 and elsewhere referred to

in full or accrued all amounts due thereunder and has satisfied in
full or provided for all of its liabilities and obligations

business, or condition, financial or otherwise, or which was entered
into other than in the ordinary course of its business. Except as

contracts or other agreements set forth on Schedule 5.11 and other
Schedules hereto continue in full force and effect following the

Except as set forth in Schedule 8.11 hereto, each of the contracts or
other agreements referred to in this Section 5.11 can be terminated
upon 90 days notice without payment of premium or penalty or any other

     5.12 Real Estate. Schedule 5.12 sets forth a list and summary
description of (i) all real property owned by the Seller and all
buildings and other structures located on such real property; (ii) all
leases, subleases or other agreements under which the Seller is lessor
or lessee of any real property; (iii) all options held by the Seller
or contractual obligations on the part of the Seller to purchase or
acquire any interest in real property; and (iv) all options granted by
the Seller or contractual obligations on the part of the Seller to
sell or dispose of any interest in real property. The Seller is the
owner of record, lessee under the leases or holder of the options, as
the case may be, as set forth on Schedule 5.12. Such leases, subleases
and other agreements are in full force and effect and the Seller has
not received any notice of any default thereunder. The Seller's
leasehold interests are subject to no lien or other encumbrance and
enjoy a right of quiet possession against any lien or encumbrance on
the property. Except as otherwise set forth on Schedule 5.12, all
improvements, structures and fixtures on the real property described
in clause (i) above or subject to the leases described in clause (ii)
above comply with all applicable ordinances, regulations or other
laws, except where the failure to be in compliance would not have a
material adverse effect on the Company Business (as defined in Section
11.1). As of the date hereof, the Seller has received no written
communications from any governmental or regulatory agency or body
regarding any alleged violation of any such ordinance, regulation or
zoning or other law affecting any such owned or leased property, and

                           - 11 -

<PAGE>

the knowledge of the Seller and the Principals, there is no pending or
threatened condemnation of any such property.

     5.13 Accounts and Notes Receivable. All accounts and notes
receivable reflected on the Balance Sheet and all accounts and notes
receivable arising subsequent to the Balance Sheet Date have arisen in
the ordinary course of business, represent valid obligations to the
Seller and, subject only to consistently recorded reserves for bad
debts, have been collected or are collectible in the aggregate
recorded amounts thereof in accordance with their terms. All items
which are required by generally accepted accounting principles to be
reflected as accounts and notes receivable on the Financials and on
the books of the Seller are so reflected.

     5.14 Inventory Valuation. The inventory of the Seller as set
forth on the Balance Sheet was, and the inventory of the Seller
currently is, in usable or salable condition in the ordinary course of
business at the amounts carried on the Balance Sheet and currently on
the books and records of the Seller, respectively. The materials,
supplies and work-in-process, and additions thereto, included in such
inventory are of at least the standard quality for such items in the
industry and are not in excess of the normal purchasing patterns of
the Seller. Neither the Seller nor either Principal knows of any
adverse condition affecting the supply of materials available to the
Seller. The amounts of the inventories reflected on the Balance Sheet
and on the books and records of the Seller have been determined in
accordance with generally accepted accounting principles consistently
applied.5.15 Tangible Property. Schedule 5.15 sets forth all interests
owned or claimed by the Seller (including, without limitation,
options) in or to the plant, machinery, equipment, furniture,
leasehold improvements, fixtures, vehicles, structures, any related

                           - 12 -

<PAGE>

capitalized items and other tangible property material to the business
of the Seller and which is treated by the Seller as depreciable or
amortizable property ("Tangible Property") not reflected on the
Balance Sheet and not sold or disposed of in the ordinary course of
business since the Balance Sheet Date. All material leases,
conditional sale contracts, franchises or licenses pursuant to which
the Seller may hold or use any interest owned or claimed by it
(including, without limitation, options) in or to Tangible Property
are in full force and effect and, with respect to the Seller's
performance, there is no default or event of default or event which
with notice or lapse of time or both would constitute a default. The
Tangible Property of the Seller is in good operating condition and
repair, and the Seller has received no notice that any of it is in
violation of any existing law or any building, zoning, health, safety
or other ordinance, code or regulation. There has never been any
significant interruption of the Seller's operations due to inadequate
maintenance of the Tangible Property.

     5.16 Intangible Property. Schedule 5.16 sets forth all patents,
trademarks, service marks, trade names and franchises, all
applications for any of the foregoing, and all permits, grants and
licenses or other rights running to or from the Seller relating to any
of the foregoing which are material to its business including, without
limitation, any patents held by Kieltyka and used in the Company
Business (the "Kieltyka Patents"). Except as set forth on Schedule
5.16, the rights of the Seller in the property set forth on Schedule
5.16 are free and clear of any liens or other encumbrances. Except as
set forth on Schedule 5.16, the Seller has no notice of any adversely
held patent, invention, trademark, service mark or trade name of any
other person or notice of any claim of any other person relating to
any of the property set forth

                           - 13 -

<PAGE>

on Schedule 5.16 or any process or confidential information of the
Seller, and neither the Seller nor either Principal knows of any basis
for any such charge or claim.

     5.17 Lists of Suppliers and Customers. Schedule 5.17 sets forth
all suppliers and customers of the Seller who have sold to or
purchased from the Seller, as the case may be, supplies, materials,
products or services during the past five years. No single supplier or
customer is of material importance to the business of the Seller. The
relationships of the Seller with its suppliers and customers are good
commercial working relationships and no supplier or customer of the
Seller has cancelled or otherwise terminated, or threatened in writing
to cancel or otherwise terminate, its relationship with the Seller or
has during the last 12 months decreased materially, or threatened to
decrease or limit materially, its services, supplies or materials to
the Seller or its usage of the Seller's services or products, as the
case may be. The Seller does not have any notice that any such
supplier or customer intends to cancel or otherwise modify its
relationship with the Seller or to decrease materially or limit its
services, supplies or materials to the Seller or its usage of the
services or products of the Seller, and the acquisition of the
Purchased Assets by the Buyer will not, to the best of the knowledge
and belief of the Seller and the Principals, adversely affect the
relationship of the Buyer (as successor to the business of the Seller)
with any such supplier or customer.

     5.18 Liens. The Seller owns outright and has good and marketable
title to all of its assets and properties, including, without
limitation, all of the assets and properties reflected on the
Financials, in each case free and clear of any lien or other
encumbrance, except for (i) immaterial assets and properties; (ii)
assets and properties disposed of, or subject to purchase or sales
orders, in the ordinary course of business since the Balance Sheet
Date; (iii)

                           - 14 -

<PAGE>

liens or other encumbrances securing taxes, assessments, governmental
charges or levies, or the claims of materialmen, carriers, landlords
and like persons, which are not yet due and payable; or (iv) minor
liens or other encumbrances of a character which do not substantially
impair the assets or properties of the Seller or materially detract
from its business.

     5.19 Indebtedness. All Indebtedness (as herein defined) of the
Seller as at the Balance Sheet Date is set forth in the Financials.
Schedule 5.19 sets forth a true and correct aged list of all accounts
payable of the Seller as of the end of the month prior to the date
hereof. All Indebtedness reflected in the Financials or on Schedule
5.19 or which has arisen after the Balance Sheet Date has arisen in
the ordinary course of business and represents valid Indebtedness of
the Seller. As used herein, the term "Indebtedness" means all items
which, in accordance with generally accepted accounting principles,
would be included on a financial statement of the Seller.

     5.20 Liabilities. As at the Balance Sheet Date, except as set
forth on Schedule 5.20, the Seller did not have any direct or indirect
indebtedness, liability, claim, loss, damage, deficiency, obligation
or responsibility, known or unknown, fixed or unfixed, choate or
inchoate, liquidated or unliquidated, secured or unsecured, accrued,
absolute, contingent or otherwise, including, without limitation,
liabilities on account of taxes, other governmental charges or
lawsuits brought, whether or not of a kind required by generally
accepted accounting principles to be set forth on a financial
statement ("Liabilities"), which were not fully and adequately
reflected on the Financials. Except as listed on Schedule 5.20, the
Seller does not have any Liabilities, other than (i) Liabilities fully
and adequately reflected on the Financials and (ii) Liabilities
incurred since the Balance Sheet Date in the ordinary course of
business.

                           - 15 -

<PAGE>

Neither the Seller nor either Principal has any knowledge of any
circumstances, conditions, events or arrangements which may hereafter
give rise to any Liabilities of the Seller or any successor to the
business of the Seller except in the ordinary course of business or as
otherwise set forth on Schedule 5.20.

     5.21 Pension and Benefit Plans and Compliance with ERISA. Except
as set forth on Schedule 5.21, the Seller is not party to, and neither
makes nor is required to make employer contributions to, any employee
benefit plan as that term is defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974 ("ERISA"), educational
assistance, auto use, fringe benefit, deferred compensation, bonus,
stock purchase, severance, stock option, vacation policy or other
employee benefit plan, agreement, arrangement or understanding
maintained for the benefit of its employees (each, an "Employee
Benefit Plan"). Each Employee Benefit Plan set forth or described on
Schedule 5.21 is in full force and effect in accordance with its terms
and complies with all applicable laws. The Seller is not in default
under any Employee Benefit Plan and, to the knowledge of the Seller
and the Principals, no other party is in default thereunder. The
Seller has made or provided for all payments due with respect to
employees of the Seller under each Employee Benefit Plan to date, and
all amounts properly accrued to date as liabilities of the Seller
under each Employee Benefit Plan in the current plan years have been
recorded on the Seller's books. The Seller maintains no "employee
pension benefit plans" (within the meaning of section 3(2) of ERISA).
The Seller maintains no multiemployer plan within the meaning of
section 3(37) of ERISA or section 414(f) of the Internal Revenue Code
of 1986, as amended (the "Code"), and has no withdrawal liability
under ERISA. All employer contributions required to be made to the
Employee Benefit Plans with

                           - 16 -

<PAGE>

respect to the Seller for all plan years-on or before the Closing will
have been made before or as of the Closing Date. To the best knowledge
of the Seller and the Principals, the Seller has satisfied all
material reporting and disclosure requirements applicable to it under
the Code or ERISA, and the Department of Labor and the Internal
Revenue Service regulations promulgated thereunder, with respect to
the Employee Benefit Plans. Nothing has occurred that would subject
any Employee Benefit Plan to liability, taxes, or penalties under
Section 4980B of the Code or Part 6 of Subtitle B of Title I of ERISA
("COBRA"). No amendment has been made increasing obligations under an
Employee Benefit Plan since the Financials. The Seller offers no
Employee Benefit Plan that provides benefits after termination of
service or retirement other than as required under COBRA. No payments
under Employee Benefit Plans will be triggered as a result of this
Agreement or the transactions contemplated hereby. No Employee Benefit
Plan has engaged in any "prohibited transaction" (within the meaning
of section 406 of ERISA or section 4975 of the Code) which could
subject such plans, the Buyer, the Seller, any trustee, administrator
or other fiduciary of such plans or any other party dealing with such
plans, to any penalty or excise tax imposed on prohibited transactions
by section 502(i) of ERISA or section 4975 of the Code.

     5.22 Insurance. Schedule 5.22 sets forth all policies or binders
of fire, liability, workmen's compensation, vehicular or other
insurance held by or on behalf of the Seller (specifying the insurer
and the policy number or covering note number with respect to binders,
and describing each pending claim thereunder). Such policies and
binders are in full force and effect. The Seller is not in default
with respect to any provision contained in any such policy

                           - 17 -

<PAGE>

or binder and has not failed to give any notice or present any claim
under any such policy or binder in due and timely fashion. Except for
claims set forth on Schedule 5.22, there are no outstanding unpaid
claims under any such policy or binder. The Seller has not received a
notice of cancellation or non-renewal of any such policy or binder.
Neither the Seller nor either Principal has any knowledge of any
inaccuracy in any application for such policies or binders, any
failure to pay premiums when due or any similar state of facts which
might form the basis for termination of any such policy or binder.

     5.23 Officers, Directors and Employees. Schedule 5.23 sets forth
the name and current annual rate of compensation of each employee,
consultant or agent of the Seller. The Seller has no present, future
or contingent liability to pay compensation for loss of office or
employment to any ex-director, ex-officer or ex-employee involved in
the Company Business. There are no amounts owing to any current or
former directors, officers or employees of Seller, other than
remuneration accrued (but not yet due for payment) in respect of the
calendar month in which the execution hereof takes place and no
current or former directors, officers or employees of Seller are
entitled to accrued holiday pay other than in respect of the Company
Business' current calendar year.

<PAGE>

services called for hereunder, the Arbitrator shall thereupon be selected by the

then the aggregate Purchase Price shall be reduced by the amount of such
deficiency. If there are any accrued and unpaid amounts set forth in the Loan
Statements, then the aggregate Purchase Price shall be reduced by an amount
equal to the amount of such accrued and unpaid amounts. The amount of any such
reductions in the Purchase Price shall be paid by the Seller or the Principals

certified or cashier's check payable to the order of the Buyer.

     11. Covenants of Seller and the Principals.

indirectly, soliciting business from any person (a "Restricted Person") that is
a customer of, or has been solicited for business by Lareau or otherwise by, the
Seller, the Buyer, or any of the Seller's or the Buyer's affiliates during the
final year of Lareau's term of employment with the Seller and/or the Buyer or

11.1 (the "Restrictive Covenants"), the Buyer shall have the following rights
and remedies, each of which shall be independent of the other and individually
or severally enforceable, and all of which shall be in addition to, and not in
lieu of, any other rights and remedies available to the Buyer under law or in
equity:

     11.2.1 Specific Performance. The right and remedy to have the Restrictive
Covenants specifically enforced by any court having equity jurisdiction, it
being acknowledged and agreed that any such breach or threatened breach will
cause irreparable injury to the Buyer and that money damages will not provide
adequate remedy to the Buyer.

     11.2.2 Accounting. The right and remedy to require the Principal or the
Seller, as the case may be, to account for and pay over to the Buyer all
compensation, profits, monies, accruals, increments or other benefits

the result of any transactions constituting a breach of any of the

                                     - 39 -

Restrictive Covenants, and the Principal or the Seller, as the case may be,
shall account for and pay over any Benefits to the Buyer.

     11.3 Unenforceability of Restrictive Covenants. (i) If any court determines
that any of the Restrictive Covenants, or any part thereof, is invalid or
unenforceable, the remainder of the Restrictive Covenants shall not thereby be
affected and shall be given full effect, without regard to the invalid
Restrictive Covenant or part thereof.

     (ii) If any court determines that any of the Restrictive Covenants, or any
part thereof, is unenforceable because of the duration of such Restrictive
Covenant or the scope of such Restrictive Covenant, such court shall have the
power to reduce the duration or scope of such Restrictive Covenant and, in its
reduced form, such Restrictive Covenant shall then be enforceable and may be
enforced.

     11.4 Enforceability in Jurisdictions. The Buyer, the Principals, and the
Seller intend to and hereby confer jurisdiction to enforce the Restrictive
Covenants upon the courts of any jurisdiction within the geographical scope of
such Covenants. If the courts of any one or more of such jurisdictions hold the
Restrictive Covenants wholly unenforceable by reason of the breadth of such
scope or otherwise, it is the intention of the Buyer, the Principals, and the
Seller that such determination not bar or in any way affect the Company's right
to the relief provided above in the courts of any other jurisdiction within the
geographical scope of such Covenants, as to breaches of such Covenants in such
other respective jurisdictions, such Covenants as they relate to each
jurisdiction being, for this purpose, severable into diverse and independent
covenants.

involving the asserted liability of the Indemnitee. In any event, the
Indemnitee, the Indemnifying Party and the Indemnifying Party's counsel shall
cooperate in the compromise of, or defense against, any such asserted liability.
Both the Indemnitee and the Indemnifying Party may participate in the defense of
such asserted liability and neither may settle or compromise any claim over the
objection of the other. If the Indemnifying Party chooses to defend any claim,
the Indemnitee shall make available to the Indemnifying Party any books, records
or other documents within its control that are necessary or appropriate for such
defense.

     13.4 Set-off Rights. Each of the Seller and the Principals agrees that the
Buyer shall have the right to set-off against the Buyer's payment obligations or
the payment obligations of any of its affiliates to the Seller and the
Principals, including, without limitation, the Buyer's payment obligations under
Section 3.2 hereof and any amounts payable by the Buyer as salary or bonus to
the Principals (the "Payment Obligations"), all or any portion of the amount of
any Losses required to be paid by the Seller and/or the Principals pursuant to
Section 13.1, if such Losses are not otherwise paid within 30 days after the
Buyer has requested payment therefor. If the Buyer elects to exercise its
set-off rights hereunder, it shall give the Seller, Kieltyka, and Lareau written
notice of such election (including the amount to be set-off), and upon giving of
such notice, the amount of any Payment Obligations shall automatically be
reduced by the amount set forth in such notice; provided that any set-off
against Lareau shall be limited to 25% of the amount set forth in such notice.
In the event there is a "final determination" by a court of competent
jurisdiction that the Buyer was not entitled to

                                     - 44 -

<PAGE>

indemnification under this Section 13.4 with respect to the set-off amount, the
Payment Obligations shall be readjusted by the Buyer in the amount to be
set-off. For purposes of this Section, a "final determination" shall mean a
determination with respect to which any and all appeals therefrom shall have
been resolved or a determination with respect to which 30 days shall have passed
from the rendering of such determination (or of any determination on appeal
therefrom) and no party shall have commenced any such appeal therefrom.

                             Counsel to the Seller]

                                                              July 1, 1997

Ladies and Gentlemen:

     We refer to the Asset Purchase Agreement dated as of July 1, 1997 (the
"Agreement"), among Bogen Communications, Inc., a Delaware corporation
("Bogen"), Bog-Comm Acquisition Corporation, a Delaware corporation (the
"Buyer"), New England Audio Resource, Inc., a Maine corporation (the "Seller"),
Mr. William Kieltyka ("Kieltyka"), and Mr. Lee Lareau ("Lareau" and together
with Kieltyka the "Principals"). For purposes of this opinion, terms used herein
have the respective meanings assigned them in the Agreement.

     We have examined the Agreement (together with the Exhibits and Schedules
thereto) and copies of the Certificate of Incorporation, By-laws and minutes of
the Seller. We have also made such other investigations of law and fact as we
have deemed necessary and relevant for the basis of our opinion.


                                     - E-3 -

<PAGE>

     Based upon the foregoing, we are of opinion that:

     1. The Seller is a corporation duly organized, validly existing and in good
standing under the laws of the State of Maine and has the corporate power and
lawful authority to own, lease and operate its assets and properties and to
carry on its business as now conducted. The Seller is qualified to transact
business and is in good standing in each jurisdiction in which the nature of its
business or location of its properties requires such qualification and in which
the failure so to qualify could have a material adverse effect on the Seller or
its assets, properties or business.

     2. The Seller is authorized to issue [____] shares of Common Stock, par
value [$_______], [_______] of which are issued and outstanding. No other class
of capital stock of the Seller is authorized or outstanding. All of the issued
shares are duly authorized and are legally and validly issued, fully paid and
nonassessable. To our knowledge, there are no outstanding options, warrants,
convertible securities, subscriptions or other commitments or rights of any
nature to acquire any securities of the Seller from the Seller.

     3. Each of the Seller, Kieltyka and Lareau has the full legal right and
power and all authority and approval required to enter into, execute and deliver
the Agreement and the Transaction Documents and to perform fully its obligations
thereunder, all such actions by the Seller have been duly authorized by all
necessary corporate proceedings on its part, and the Agreement has been duly
executed and delivered by each of the Seller, Kieltyka and Lareau and
constitutes the valid and binding obligation of each of them and is enforceable
in accordance with its terms.

                                     - E-4 -

<PAGE>

     4. No approval or consent of any foreign, federal, state, county, local or
other governmental or regulatory body, and no approval or consent of any other
person (except as otherwise specified in the Agreement or Schedules thereto,
which approvals and consents have been obtained and are in full force and
effect) is required in connection with the execution and delivery by the Seller,
Kieltyka and Lareau of this Agreement and the consummation and performance by
each of them of the transactions contemplated hereby.

     5. The execution and delivery of the Agreement and the Transaction
Documents and the consummation of the transactions contemplated thereunder and
the performance by the Seller of each of the Agreement and the Transaction
Documents in accordance with its terms and conditions will not (a) conflict with
or result in the breach or violation of any of the terms or conditions of, or
constitute (or with notice or lapse of time or both would constitute) a default
under, (i) the Certificate of Incorporation or By-laws of the Seller, (ii) any
instrument, contract, license or other agreement known to us, after due inquiry,
to which the Seller is a party or by or to which it or any of its assets or
properties is bound or subject, (iii) any statute or any regulation, order,
judgment or decree of any court or governmental or regulatory agency or body, or
(iv) any Permit or (b) result in the creation or imposition of any lien, claim,
charge, restriction, security interest or encumbrances upon any of the Purchased
Assets.

     6. The instruments of sale, conveyance, assignment and transfer executed
and delivered by the Seller to the Buyer pursuant to the Agreement have been
duly executed and such documents effectively vest in the Buyer all of the
Purchased Assets, all free and clear of any lien, claim, charge, restriction,
security interest and other encumbrance. The Patent Assignment executed and
delivered by Kieltyka to the Buyer has been duly executed and such document

                                     - E-5 -

<PAGE>

effectively vests in the Buyer the Kieltyka Patents, free and clear of
any lien, claim, charge, restriction, security interest or other encumbrance.

     7. To our knowledge, after due inquiry, none of the Seller, Kieltyka and
Lareau is a party to, or threatened with, any litigation or judicial,
administrative or arbitration proceeding or has incurred or been charged with or
been under investigation with respect to any violation of any foreign, federal,
state, county, or local law or administrative regulation.

     We express no opinion as to the effect of (i) applicable bankruptcy and
other similar laws affecting the rights of creditors generally, or (ii) rules of
law governing specific performance, injunctive relief or other equitable
remedies.

     We are members of the Bar of the State of Maine and in this letter we
express no opinion with respect to the laws of any jurisdiction other than those
of the State of Maine and the federal laws of the United States of America.
Without limiting the foregoing qualification, I have expressly assumed with your
permission that the applicable laws of any jurisdiction other than the State of
Maine and the United States of America are substantially the same as those of
the State of Maine.

                                               Very truly yours,

                                               Ranger, Copeland & Willcox, P.A.
