Board of Directors
Industrial Acoustics Company, Inc.

Bronx, NY 10462


Dear Sirs:


     You have asked us to advise you with respect to the fairness to the
minority, public stockholders of IAC Inc. (the "Company") from a financial point
of view of the consideration to be paid by IAC Holdings ("Holdings") pursuant to
the terms of the Agreement and Plan of Merger (the "Merger Agreement"), between
the Company and Holdings. The Merger Agreement provides that for each
outstanding share of the Company's Common Stock the shareholder will receive
$11.00 in cash.

     In arriving at our opinion, we have reviewed certain publicly available
business and financial information relating to the Company. We have also
reviewed certain other information, including financial forecasts, provided to
us by the Company, and have met with the Company's and Holdings' management to
discuss the business and prospects of the Company.

     We have also considered certain financial and stock market data of the
Company. We also considered such other information, financial studies, analyses
and investigations and financial, economic and market criteria which we deemed
relevant.

     In connection with our review, we have not independently verified any of
the foregoing information and have relied on its being complete and accurate in
all material respects. With respect to the financial forecasts, we have assumed
that they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the Company's and Holdings' management as
to the future financial performance of the Company. In addition, we have not
made an independent evaluation or appraisal of the as-


<PAGE>
                                      -2-


sets of the Company, nor have we been furnished with any such appraisals.
Laidlaw will receive a fee for rendering this opinion.

     It is understood that this letter is for the information of the Board of
Directors of IAC Inc. only and may be published in its entirety in the
prospectus/proxy statement to be distributed to stockholders of the Company so
long as we give our prior written consent to any summary of, excerpt from or
reference to such opinion which consent shall not be unreasonably withheld. This
letter is not to be quoted or referred to, in whole or in part, in any other
proxy statement or in any other registration statement or prospectus, or in any
other document used in connection with the offering or sale of securities, nor
shall this letter be used for any other purposes, without Laidlaw & Co.'s prior
written consent.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the consideration to be paid to the Company's minority, public
stockholders pursuant to the Merger Agreement is fair from a financial point of
view.


                                       Sincerely,



                                       Laidlaw Global Securities, Inc.

                                      -31-


Company or any Subsidiary, as the case may be, after the Closing in the same

     (l) Either the Company or a Subsidiary, as the case may be, has the full
fight to exercise any renewal options contained in the leases and subleases
pertaining to the Leased Real Property on the terms and conditions contained

the Company or a Subsidiary, as the case may be, owns, leases or has the legal
right to use all the properties and assets, including, without limitation, the

and rights as are necessary in the conduct of, the business of the Company and
its Subsidiaries. At all times since the date of the Reference Balance Sheet,
the Company has caused the Assets to be maintained in accordance with good

     (c) Following the consummation of the transactions contemplated by this

limitation, any increase in rentals, royalties, or licenses or other fees

the Subsidiaries for the twelve-month period ended December 31, 1997 and the
amount for which each such customer was invoiced during such period. Except as

invoiced the Company and the Subsidiaries during such period. Except as
disclosed in Section 3.25 of the Disclosure Schedule, none of Hirschorn, the

that any such supplier will not sell raw materials, supplies, merchandise and
other goods to the Company or any Subsidiary at any time after the Closing Date
on terms and conditions substantially similar to those used in its current sales
to the Company and the Subsidiaries, subject only to general and customary price
increases.

     3.26. EMPLOYEE BENEFIT MATTERS.

     (a) Plans and Material Documents. Section 3.26(a) of the Disclosure
Schedule lists (i) all employee benefit plans (as defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")) and all
bonus, stock option, stock purchase, restricted stock, incentive, deferred
compensation, retiree medical or life insurance, supplemental retirement,
severance or other benefit plans, programs or arrangements, and all employment,
termination, severance or other contracts or agreements, whether legally
enforceable or not, to which the Company or any Subsidiary is a party, with

maintained, contributed to or sponsored by the Company or any Subsidiary for the
benefit of any current or former employee, officer or director of the Company or
any Subsidiary, (ii) each employee benefit plan for which the Company or any

<PAGE>
                                      -35-


employee of the Company or of any Subsidiary, including, without limitation, any
contracts, arrangements or understandings relating to the sale of the Company
(collectively, the "Plans"). Each Plan is in writing and Hirschorn has made
available to the Buyer complete and accurate copies of each Plan and a complete
and accurate copy of each material document prepared in connection with each
such Plan including, without limitation, (i) a copy of each trust or other
funding arrangement, (ii) each summary plan description and summary of material
modifications, (iii) the most recently filed IRS Form 5500, (iv) the most
recently received IRS determination letter for each such Plan, and (v) the most
recently prepared actuarial report and financial statement in connection with
each such Plan. Except as disclosed on Section 3.26(a) of the Disclosure
Schedule, there are no other employee benefit plans, programs, arrangements or
agreements, whether formal or informal, whether in writing or not, to which the
Company or any Subsidiary is a party, with respect to which the Company or any
Subsidiary has any obligation or which are maintained, contributed to or
sponsored by the Company or any Subsidiary for the benefit of any current or
former employee, officer or director of the Company or any Subsidiary. Neither
the Company nor any Subsidiary has any express or implied material commitment,
whether legally enforceable or not, (i) to create, incur liability with respect
to or cause to exist any other employee benefit plan, program or arrangement,
(ii) to enter into any contract or agreement to provide compensation or benefits
to any individual or (iii) to modify, change or terminate any Plan, other than
with respect to a modification, change or termination required by ERISA or the
Code.

     (b) Absence of Certain Types of Plans. None of the Plans is a single
employer pension plan (within the meaning of Section 4001(a)(15) of ERISA) for
which the Company or any Subsidiary could incur liability under Section 4063 or
4064 of ERISA. None of the Plans provides for the payment of separation,
severance, termination or similar-type benefits to any Person or obligates the
Company or any Subsidiary to pay separation, severance, termination or
similar-type benefits solely as a result of any transaction contemplated by this
Agreement or as a result of a "change in control," within the meaning of such
term under Section 280G of the Code. None of the Plans provides for or promises
retiree medical, disability or life insurance benefits to any current or former
employee, officer or director of the Company or any Subsidiary for which
accruals have not been taken. Any such accruals are listed on the Reference
Balance Sheet. Except for those Plans of Industrial Acoustics Company Limited,
each of the Plans is subject only to the laws of the United States or a
political subdivision thereof.

     (c) Compliance with Applicable Law. Each Plan is now and always has been
operated in all respects in accordance with the requirements of all applicable
Law, including, without limitation, ERISA and the Code, and all persons who
participate in the operation of such Plans and all Plan "fiduciaries" (within
the meaning of Section 3(21) of ERISA) have always acted in accordance with the
provisions of all applicable Law, including, without limitation, ERISA and the
IRC. The Company and each Subsidiary has performed all 


<PAGE>
                                      -36-


obligations required to be performed by it under, is not in any respect in
default under, or in violation of, and has no knowledge of any default or
violation by any party to any Plan. No legal action, suit or claim is pending or
threatened with respect to any Plan (other than claims for benefits in the
ordinary course) and no fact or event exists that could give rise to any such
action, suit or claim.

     (d) Qualification of Certain Plans. Each Plan which is intended to be
qualified under Section 401(a) of the IRC or Section 401(k) of the IRC has
received a favorable determination letter from the IRS that it is so qualified
and each trust established in connection with any Plan which is intended to be
exempt from federal income taxation under Section 501(a) of the IRC has received
a determination letter from the IRS that it is so exempt and no fact or event
has occurred since the date of such determination letter from the IRS to
adversely affect the qualified status of any such Plan or the exempt status of
any such trust. Each trust maintained or contributed to by the Company or any
Subsidiary which is intended to be qualified as a voluntary employees'
beneficiary association and which is intended to be exempt from federal income
taxation under Section 501(c)(9) of the IRC has received a favorable
determination letter from the IRS that it is so qualified and so exempt, and no
fact or event has occurred since the date of such determination by the IRS to
adversely affect such qualified or exempt status.

     (e) Absence of Certain Liabilities and Events. There has been no prohibited
transaction (within the meaning of Section 406 of ERISA or Section 4975 of the
IRC) with respect to any Plan. Neither the Company nor any Subsidiary has
incurred any liability for any penalty or tax arising under Section 4971, 4972,
4980, 4980B or 6652 of the IRC or any liability under Section 502 of ERISA and
no fact or event exists which could give rise to any such liability. Neither the
Company nor any Subsidiary has incurred any liability under, arising out of or
by operation of Title IV of ERISA (other than liability for premiums to the
Pension Benefit Guaranty Corporation arising in the ordinary course), including,
without limitation, any liability in connection with (i) the termination or
reorganization of any employee benefit plan subject to Title IV of ERISA or (ii)
the withdrawal from any multiemployer plan (within the meaning of Section 3(37)
or 4001(a)(3) of ERISA, and no fact or event exists which could give rise to any
such liability. Except as set forth on Section 3.26(e) of the Disclosure
Schedule, no complete or partial termination has occurred within the five years
preceding the date hereof with respect to any Plan. No reportable event (within
the meaning of Section 4043 of ERISA) has occurred or is expected to occur with
respect to any Plan subject to Title IV of ERISA. No Plan had an accumulated
funding deficiency (within the meaning of Section 302 of ERISA or Section 412 of
the Code) whether or not waived as of the most recently ended plan year of such
Plan. None of the assets of the Company or any Subsidiary is the subject of any
lien arising under Section 302(f) of ERISA or Section 412(n) of the Code;
neither the Company nor any Subsidiary has been required to post any security
un-


<PAGE>
                                      -37-


der Section 307 of ERISA or Section 401(a)(29) of the Code; and no fact or event
exists which could give rise to any such lien or requirement to post any such
security.

     (f) Plan Contributions and Funding. All contributions, premiums or payments
required to be made with respect to any Plan (and any other employee benefit
plan for which the Company or any Subsidiary may have liability for funding)
have been made on or before their due dates. All such contributions have been
fully deducted for income tax purposes and no such deduction has been challenged
or disallowed by any government entity and no fact or event exists which could
give rise to any such challenge or disallowance. As of the Closing Date, no Plan
which is subject to Title IV of ERISA will have an "unfunded benefit liability"
(within the meaning of Section 4001(a)(18) of ERISA).

     (g) Certain Employee-Benefits Assets. Each of the guaranteed investment
contracts and other funding contracts with any insurance company that are held
by any of the Plans and any annuity contracts purchased by (i) any of the Plans
or (ii) any pension benefit plans (as defined in Section 3(2) of ERISA) that
provided benefits to any current or former employees of the Company or any
Subsidiary was issued by an insurance company which carried the highest rating
from each of Duff & Phelps Credit Rating Co., Standard & Poor's Insurance Rating
Services, A.M. Best Company and Moody's Investors Service, as of the date such
contract was issued, the date hereof and the Closing Date.

     (h) WARN Act. The Company and the Subsidiaries are in compliance with the
requirements of the Workers Adjustment and Retraining Notification Act ("WARN")
and have no liabilities pursuant to WARN.

     (i) Americans With Disability Act. Except as set forth in Section 3.26(i)
of the Disclosure Schedule, the Seller has no Knowledge that the Company and
each Subsidiary are not in compliance with the requirements of the Americans
With Disabilities Act.

     (j) Withdrawal Liability. Neither the Company nor any Subsidiary has
announced an intention to withdraw, but has not yet completed withdrawal, from a
multiemployer plan. No action has been taken that could result in either a
partial or complete withdrawal from a multiemployer plan by the Company or any
Subsidiary.

     3.27. LABOR RELATIONS; COMPLIANCE.

     The Company or one of its Subsidiaries is a party to those collective
bargaining or other labor Contracts set forth on Section 3.27 of the Disclosure
Schedule. Except as set forth on Section 3.27 of the Disclosure Schedule, since
January 1, 1994, there has not been, there is not presently pending or existing,
and to Hirschorn's Knowledge there is not threatened, (a) any strike, slowdown,
picketing, work stoppage, or employee grievance process, (b) any Proceeding
against or affecting the Company or any of its Subsidiaries relating to the

<PAGE>
                                      -38-


alleged violation of any Legal Requirement pertaining to labor relations or
employment matters, including any charge or complaint filed by an employee or
union with the National Labor Relations Board, the Equal Employment Opportunity
Commission, or any comparable Governmental Body, organizational activity, or
other labor or employment dispute against or affecting any of the Company and
its Subsidiaries or their premises, or (c) any application for certification of
a collective bargaining agent. To Hirschorn's Knowledge, no event has occurred
or circumstance exists that could provide the basis for any work stoppage or
other labor dispute. There is no lockout of any employees by the Company or any
of its Subsidiaries, and no such action is contemplated by the Company or any of
its Subsidiaries. The Company and each of the Subsidiaries have complied in all
respects with all Legal Requirements relating to employment, equal employment
opportunity, nondiscrimination, immigration, wages, hours, benefits, collective
bargaining, the payment of social security and similar taxes, occupational
safety and health, and plant closing. Neither the Company nor any Subsidiary is
liable for the payment of any compensation, damages, taxes, fines, penalties, or
other amounts, however designated, for failure to comply with any of the
foregoing Legal Requirements.

     3.28. KEY EMPLOYEES.

employment, nature of employment (whether contractual or at will), and a
description of position and job function of each current salaried employee,
officer, director, consultant or agent of the Company or any Subsidiary whose
annual compensation exceeded (or, in 1997, is expected to exceed) $100,000.00.

     (b) All directors, officers, management employees, and technical and
professional employees of the Company and each Subsidiary are under written
obligation to the Company or such Subsidiary to maintain in confidence all
confidential or proprietary information acquired by them in the course of their
employment and to assign to the Company or such Subsidiary all inventions made
by them within the scope of their employment during such employment and for a
reasonable period thereafter.

     3.29. TAXES.

     (a) The Company and its Subsidiaries have filed or caused to be filed all
Tax Returns that are or were required to be filed by or with respect to any of
them, either separately or as a member of a group of corporations, pursuant to
applicable Legal Requirements. The Company has made available to Buyer copies of
all such Tax Returns relating to income or franchise taxes filed since January
1, 1992. The Company and its Subsidiaries (i) have timely paid, or made
provision for the payment of, all Taxes that have or may have become due
pursuant to those Tax Returns or otherwise, or pursuant to any assessment
received by the 


<PAGE>
                                      -39-


Company or any of its Subsidiaries, except such Taxes, if any, as are listed in
Section 3.29 of the Disclosure Schedule and are being contested in good faith
and as to which adequate reserves (determined in accordance with GAAP) have been
provided in the Reference Balance Sheet and the Interim Balance Sheet, and (ii)
have made adequate provision (through a current accrual on the Reference Balance
Sheet) for any Taxes attributable to any taxable period (or portion thereof) of
the Company and/or its Subsidiaries ending on or prior to the date hereof that
are not yet due and payable.

     (b) The United States federal income Tax Returns of the Company and each of
its subsidiaries subject to such Taxes have been audited by the IRS or are
closed by the applicable statute of limitations for all taxable years through
December 31, 1995. The New York State income Tax Returns of the Company and each
of its subsidiaries subject to such Taxes have been audited by the relevant
state tax authorities or are closed by the applicable statute of limitations for
all taxable years through December 31, 1994. The New York City income Tax
Returns of the Company and each of its subsidiaries subject to such Taxes have
been audited by the relevant tax authorities or are closed by the applicable
statute of limitations for all taxable years through December 31, 1992. The
United Kingdom income Tax Returns of the Company and each of its subsidiaries
subject to such Taxes have been audited by Inland Reserve or are closed by the
applicable statute of limitations for all taxable years through December 31,
1996. Hirschorn has made available to Buyer a complete and accurate list of all
audits of all such Tax Returns, including a reasonably detailed description of
the nature and outcome of each audit. All deficiencies proposed as a result of
such audits have been paid, reserved against or settled. Except as described in
Section 3.29 of the Disclosure Schedule, neither the Company nor any of the
Subsidiaries has given or been requested to give waivers or extensions (or is or
would be subject to a waiver or extension given by any other Person) of any
statute of limitations relating to the payment of Taxes of the Company or any of
its Subsidiaries or for which the Company or any of its Subsidiaries may be
liable.

     (c) The charges, accruals, and reserves with respect to Taxes on the
respective books of the Company and each of its Subsidiaries are adequate
(determined in accordance with GAAP) and are at least equal to the Company's or
such Subsidiary's liability for Taxes. There exists no proposed tax assessment
against the Company or any of its Subsidiaries except as disclosed in the
Balance Sheet or in Section 3.29 of the Disclosure Schedule. No consent to the
application of Section 3.41(f)(2) of the IRC has been filed with respect to any
property or assets held, acquired, or to be acquired by the Company or any of
its Subsidiaries. All Taxes that the Company or any of its Subsidiaries is or

Governmental Body or other Person.

     9. TERMINATION.

     This Agreement may, by notice given prior to or at the Closing, be
terminated:

          (a) by either Buyer or Seller if a material Breach of any provision of
     this Agreement has been committed by the other party, such material Breach
     has not been cured after notice and a reasonable period of time to cure,
     and such Breach has not been waived;

          (b) (i) by Buyer if any of the conditions in Section 7 has not been
     satisfied as of the Closing Date or if satisfaction of such a condition is
     or becomes impossible (other than through the failure of Buyer to comply
     with its obligations under this Agreement) and Buyer has not waived such
     condition on or before the Closing Date; or (ii) by Seller, if any of the
     conditions in Section 8 has not been satisfied of the Closing Date or if

<PAGE>
                                      -53-


     the failure of Seller to comply with his obligations under this Agreement)
     and Seller has not waived such condition on or before the Closing Date;

          (c) by Buyer if, between the date hereof and the Closing Date: (i) an
     event or condition occurs that has resulted in or that may be expected to
     result in a Material Adverse Effect, (ii) any material representation or
     warranty of Seller contained in this Agreement shall not have been true and
     correct when made, (iii) Seller shall not have complied with any material
     covenant or agreement to be complied with by it and contained in this
     Agreement; or (iv) Seller, the Company or any Subsidiary makes a general
     assignment for the benefit of creditors, or any proceeding shall be
     instituted by or against Seller, the Company or any Subsidiary seeking to

     winding up or reorganization, arrangement, adjustment, protection, relief
     or composition of its debts under any law relating to bankruptcy,
     insolvency or reorganization;

          (d) by mutual consent of Buyer and Seller; or

          (e) by either Buyer or Seller if the Closing has not occurred (other
     than through the failure of any party seeking to terminate this Agreement
     to comply fully with its obligations under this Agreement) on or before
     April 30, 1998 or such later date as the parties may agree upon.

     9.2. EFFECT OF TERMINATION.

     Each party's right of termination under Section 9.1 is in addition to any
other rights it may have under this Agreement or otherwise, and the exercise of
a right of termination will not be an election of remedies. If this Agreement is
terminated pursuant to Section 9.1, all further obligations of the parties under
this Agreement will terminate, except that the obligations in Sections 11.1 and
11. 3 will survive; provided, however, that if this Agreement is terminated by a
party because of the Breach of the Agreement by the other party or because one
or more of the conditions to the terminating party's obligations under this
Agreement is not satisfied as a result of the other party's failure to comply
with its obligations under this Agreement, the terminating party's right to
pursue all legal remedies will survive such termination unimpaired.


     10. INDEMNIFICATION; REMEDIES.

     10.1. SURVIVAL.

     All representations, warranties, covenants, and obligations in this
Agreement, the Disclosure Schedule, the supplements to the Disclosure Schedule,
the certificate delivered 


<PAGE>
                                      -54-


pursuant to Section 2.4(a)(ii), and any other certificate or document delivered
pursuant to this Agreement will survive the Closing.

     10.2. INDEMNIFICATION AND PAYMENT OF DAMAGES BY SELLER.

     Seller will indemnify and hold harmless Buyer, the Company and its
Subsidiaries, and their respective Representatives, stockholders, controlling
persons, and affiliates (collectively, the "Indemnified Persons") for, and will
pay to the Indemnified Persons the amount of, 74% any loss, liability, claim,
damage (including incidental and consequential damages), expense (including
costs of investigation and defense and reasonable attorneys' fees) or diminution
of value, whether or not involving a third-party claim (collectively,
"Damages"), arising, directly or indirectly, from or in connection with:

          (a) any Breach of any representation or warranty made by Seller in
     this Agreement, the Disclosure Schedule, the supplements to the Disclosure
     Schedule, or any other certificate or document delivered by Seller pursuant
     to this Agreement;

          (b) any Breach of any representation or warranty made by Seller in
     this Agreement as if such representation or warranty were made on and as of
     the Closing Date, other than any such Breach that is disclosed in a
     supplement to the Disclosure Schedule and is expressly identified in the
     certificate delivered pursuant to Section 2.4(a)(ii) as having caused the
     condition specified in Section 7.1 not to be satisfied;

          (c) any Breach by Seller of any covenant or obligation of Seller in
     this Agreement;

          (d) any product shipped or manufactured by, or any services provided
     by, the Company or any of its Subsidiaries prior to the Closing Date;

          (e) any claim by any Person for brokerage or finder's fees or
     commissions or similar payments based upon any agreement or understanding
     alleged to have been made by any such Person with either Seller or the
     Company or any of its Subsidiaries (or any Person acting on their behalf)
     in connection with any of the Contemplated Transactions; and

          (f) any Taxes of the Company and/or its Subsidiaries with respect to
     any Tax year or portion thereof ending on or before the Closing Date (or
     for any Tax year beginning before and ending after the Closing Date, to the
     extent allocable to the portion of such period beginning before and ending
     on the Closing Date), to the extent such Taxes are not reflected in the
     reserve for Tax liabilities shown on the Interim Bal-


<PAGE>
                                      -55-


     ance Sheet, as such reserve is adjusted for the passage of time through the
     closing date in accordance with the past practice and custom of the Company
     and its Subsidiaries in filing their Tax Returns.

     Buyer shall request payment of Damages to be made by a claim against funds
held in escrow pursuant to the Escrow Agreement.

     10.3. TIME LIMITATIONS.

     If the Closing occurs, Seller will have no liability (for indemnification
or otherwise) with respect to any representation or warranty, or covenant or
obligation to be performed and complied with prior to the Closing Date, other
than those in Section 3.2, 3.18 and 3.29, unless on or before eighteen (18)
months from the Closing Date Buyer notifies Seller of a claim specifying the
factual basis of that claim in reasonable detail to the extent then known by
Buyer; a claim with respect to Section 3.2 or 3.29 may be made at any time until
five (5) years from the Closing Date; and a claim with respect to Section 3.18
may be made at any time until thirty (30) months from the Closing Date.

     10.4. LIMITATIONS ON AMOUNT -- SELLER.

     Seller will have no liability (for indemnification or otherwise) with
respect to the matters described in clause (a), clause (b), to the extent
relating to any failure to perform or comply prior to the Closing Date, clause
(c), clause (d) or clause (f) of Section 10.2, until the total of all Damages
with respect to such matters exceeds $250,000.00, at which time all such Damages
shall become due (not just the amounts in excess of $250,000.00). For purposes
of the preceding sentences, Damages shall not include amounts that individually
do not result in a loss of at least $5,000.00. The maximum amount of Seller's
total liability (for indemnification or otherwise) shall be $1,750,000.00.

     10.5. PROCEDURE FOR INDEMNIFICATION -- THIRD-PARTY CLAMS.

     (a) Promptly after receipt by an indemnified party under Section 10.2 of
notice of the commencement of any Proceeding against it, such indemnified party
will, if a claim is to be made against an indemnifying party under such Section,
give notice to the indemnifying party of the commencement of such claim, but the
failure to notify the indemnifying party will not relieve the indemnifying party
of any liability that it may have to any indemnified party, except to the extent
that the indemnifying party demonstrates that the defense of such action is
prejudiced by the indemnifying party's failure to give such notice.

     (b) If any Proceeding referred to in Section 10.5(a) is brought against an
indemnified party and it gives notice to the indemnifying party of the
commencement of such 


<PAGE>
                                      -56-


Proceeding, the indemnifying party will, unless the claim involves Taxes, be
entitled to participate in such Proceeding and, to the extent that it wishes
(unless (i) the indemnifying party is also a party to such Proceeding and the
indemnified party determines in good faith that joint representation would be
inappropriate, or (ii) the indemnifying party fails to provide reasonable
assurance to the indemnified party of its financial capacity to defend such
Proceeding and provide indemnification with respect to such Proceeding), to
assume the defense of such Proceeding with counsel satisfactory to the
indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Section 10 for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding, in
each case subsequently incurred by the indemnified party in connection with the
defense of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying
party without the indemnified party's consent unless (A) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that may be made against the
indemnified party, and (B) the sole relief provided is monetary damages that are
paid in full by the indemnifying party; and (iii) the indemnified party will
have no liability with respect to any compromise or settlement of such claims
effected without its consent. If notice is given to an indemnifying party of the
commencement of any Proceeding and the indemnifying party does not, within ten
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will be bound by any determination made in such Proceeding or
any compromise or settlement effected by the indemnified party.

     (c) Notwithstanding the foregoing, if an indemnified party determines in
good faith that there is a reasonable probability that a Proceeding may
adversely affect it or its affiliates other than as a result of monetary damages
for which it would be entitled to indemnification under this Agreement, the
indemnified party may, by notice to the indemnifying party, assume the exclusive
right to defend, compromise, or settle such Proceeding, but the indemnifying
party will not be bound by any determination of a Proceeding so defended or any
compromise or settlement effected without its consent (which may not be
unreasonably withheld).

     10.6. PROCEDURE FOR INDEMNIFICATION -- OTHER CLAIMS.

     A claim for indemnification for any matter not involving a third-party
claim may be asserted by notice to the party from whom indemnification is
sought.

     Except as otherwise expressly provided in this Agreement, each party to
this Agreement will bear its respective expenses incurred in connection with the
preparation, execution, and performance of this Agreement and the Contemplated
Transactions, including all fees and expenses of agents, representatives,
counsel, and accountants. Buyer and Seller will each pay their respective HSR
Act filing fees. Seller will cause the Company and its Subsidiaries not to incur
any out-of-pocket expenses in connection with this Agreement except for
professional fees and environmental survey fees not in excess of $50,000.00. In
the event of termination of this Agreement, the obligation of each party to pay
its own expenses will be subject to any rights of such party arising from a
breach of this Agreement by another party.

     11.2. PUBLIC ANNOUNCEMENTS.

     Any public announcement or similar publicity with respect to this Agreement
or the Contemplated Transactions will be issued, if at all, at such time and in
such manner as Seller and the Buyer jointly determine. Unless consented to by
Buyer in advance or required by Legal Requirements, prior to the Closing Seller
shall, and shall cause the Company and its Subsidiaries to, keep this Agreement
strictly confidential and may not make any disclosure of this Agreement to any
Person. Seller and Buyer will consult with each other concerning the means by
which the Company's and its Subsidiaries' employees, customers, and suppliers
and others having dealings with the Company and its Subsidiaries will be
informed of the Contemplated Transactions, and Buyer will have the right to be
present for any such communication.

     11.3. CONFIDENTIALITY.

     Between the date of this Agreement and the Closing Date, Buyer and Seller
will maintain in confidence, and will cause the directors, officers, employees,
agents, and advisors of Buyer and the Company and its Subsidiaries to maintain
in confidence, and not use to the detriment of another party or the Company or
any of its Subsidiaries, any written, oral, or other information obtained in
confidence from, written information stamped "confidential" when originally
furnished by another party or the Company or any of its Subsidiaries in
connection with this Agreement or the Contemplated Transactions, unless (a) such
information is already known to such party or to others not bound by a duty of
confidentiality or such information becomes publicly available through no fault
of such party, (b) the use of such information is necessary or appropriate in
making any filing or obtaining any consent or approval required for the
consummation of the Contemplated Transactions, or (c) the furnishing or use of
such information is required by legal proceedings.


<PAGE>
                                      -58-


     If the Contemplated Transactions are not consummated, each party will
return or destroy as much of such written information as the other party may
reasonably request.

     11.4. NOTICES.

Agreement must be in writing and will be deemed to have been duly given when (a)
delivered by hand (with written confirmation of receipt), (b) sent by telecopier

addressee, if sent by a nationally recognized overnight delivery service

     11.5. JURISDICTION; SERVICE OF PROCESS.

     Any action or proceeding seeking to enforce any provision of, or based on
any right arising out of, this Agreement may be brought against any of the
parties in the courts of the State of New York, County of New York, or, if it
has or can acquire jurisdiction, in the United States District Court for the
Southern District of New York, and each of the parties 


<PAGE>
                                      -59-


consents to the jurisdiction of such courts (and of the appropriate appellate
courts) in any such action or proceeding and waives any objection to venue laid
therein. Process in any action or proceeding referred to in the preceding
sentence may be served on any party anywhere in the world.

     11.6. FURTHER ASSURANCES.

     The parties agree (a) to furnish upon request to each other such further
information, (b) to execute and deliver to each other such other documents, and
(c) to do such other acts and things, all as the other party may reasonably
request for the purpose of carrying out the intent of this Agreement and the
documents referred to in this Agreement.

     11.7. WAIVER.

     The rights and remedies of the parties to this Agreement are cumulative and
not alternative. Neither the failure nor any delay by any party in exercising
any right, power, or privilege under this Agreement or the documents referred to
in this Agreement will operate as a waiver of such right, power, or privilege,
and no single or partial exercise of any such right, power, or privilege will
preclude any other or further exercise of such right, power, or privilege or the
exercise of any other right, power, or privilege. To the maximum extent
permitted by applicable law, (a) no claim or right arising out of this Agreement
or the documents referred to in this Agreement can be discharged by one party,
in whole or in part, by a waiver or renunciation of the claim or right unless in
writing signed by the other party; (b) no waiver that may be given by a party
will be applicable except in the specific instance for which it is given; and
(c) no notice to or demand on one party will be deemed to be a waiver of any
obligation of such party or of the right of the party giving such notice or
demand to take further action without notice or demand as provided in this
Agreement or the documents referred to in this Agreement.

     11.8. ENTIRE AGREEMENT AND MODIFICATION.

     This Agreement supersedes all prior agreements between the parties with
respect to its subject matter, including the Letter of Intent between the
predecessor to the Buyer and Seller dated November 3, 1997 and the modification
to the Letter of Intent dated December 23, 1997, and constitutes (along with the
documents referred to in this Agreement) a complete and exclusive statement of
the terms of the agreement between the parties with respect to its subject
matter. This Agreement may not be amended except by a written agreement executed
by the party to be charged with the amendment.

     11.9. DISCLOSURE SCHEDULE.

     (a) The disclosures in the Disclosure Schedule, and those in any Supplement
thereto, must relate only to the representations and warranties in the Section
of the Agreement to which they expressly relate and not to any other
representation or warranty in this Agreement.

     (b) In the event of any inconsistency between the statements in the body of
this Agreement and those in the Disclosure Schedule (other than an exception
expressly set forth as such in the Disclosure Schedule with respect to a
specifically identified representation or warranty), the statements in the body
of this Agreement will control.

     11.10. ASSIGNMENT; SUCCESSORS, AND NO THIRD-PARTY RIGHTS.

     Neither party may assign any of its rights under this Agreement without the
prior consent of the other parties. Subject to the preceding sentence, this
Agreement will apply to, be binding in all respects upon, and inure to the
benefit of the successors and permitted assigns of the parties. Nothing
expressed or referred to in this Agreement will be construed to give any Person
other than the parties to this Agreement any legal or equitable right, remedy,
or claim under or with respect to this Agreement or any provision of this
Agreement. This Agreement and all of its provisions and conditions are for the
sole and exclusive benefit of the parties to this Agreement and their successors
and assigns.

     11.11. SEVERABILITY.

     If any provision of this Agreement is held invalid or unenforceable by any
court of competent jurisdiction, the other provisions of this Agreement will
remain in full force and effect. Any provision of this Agreement held invalid or
unenforceable only in part or degree will remain in full force and effect to the
extent not held invalid or unenforceable.

     11.12. SECTION HEADINGS; CONSTRUCTION.

     The headings of Sections in this Agreement are provided for convenience
only and will not affect its construction or interpretation. All references to
"Section" or "Sections" refer to the corresponding Section or Sections of this
Agreement. All words used in this Agreement will be construed to be of such
gender or number as the circumstances require. Unless otherwise expressly
provided, the word "including" does not limit the preceding words or terms.

without regard to conflicts of laws principles.

     11.14. COUNTERPARTS.

Introduction and Summary

     Place; Record Date; Quorum; Solicitation. This Proxy Statement is furnished
in connection with the solicitation by Industrial Acoustics Company, Inc., a New
York corporation (the "Company" or "IAC") for use at a special meeting (the
"Meeting") of the Company's shareholders (the "Shareholders") to be held on
__________, 1998 at 10:00 a.m. at the Company's principal executive offices
located at 1160 Commerce Avenue, Bronx, New York, 10462, and at any
postponements or adjournments thereof. The approximate date on which a
definitive Proxy Statement and the accompanying proxy will first be mailed to
shareholders is __________, 1998.

     Only Shareholders of record at the close of business on , 1998 (the "Record
Date"), will be entitled to vote at the Meeting. On that date, there were
2,981,211 shares of the Common Stock of the Company, par value $.10 (the "Common
Stock") outstanding and entitled to vote at the Meeting held by approximately
600 shareholders of rec-


<PAGE>

ord. Based on a statement filed by IAC Holdings Corp. ("Holdings") (a holding
company whose principal assets consist of Common Stock of the Company and whose
principal executive offices are located at 100 First Stamford Place, Stamford,
Connecticut 06902), on Schedule 13D, the Company believes that Holdings owns
2,353,904 shares of Common Stock, representing approximately 79% of the
outstanding shares of Common Stock. The sole shareholder of Holdings is
International Mezzanine Investment, N.V. ("IMI"), a Netherlands Antilles
corporation whose principal executive offices are located at John B. Gorsiraweg
14 Curacao, Netherlands Antilles. The presence at the Meeting, in person or by
proxy, of a majority of the outstanding shares of Common Stock entitled to vote
shall constitute a quorum for the meeting.

     Common Stock represented by properly executed proxies, unless previously
revoked, will be voted at the Meeting in accordance with the instructions
thereon. Each proxy granted may be revoked by a Shareholder giving such proxy at
any time before it is exercised by filing with the Secretary of the Company a
revoking instrument or a duly executed proxy bearing a later date. The powers of
any proxy holder will be suspended if the person who executed the proxy held by
such proxy holder attends the Meeting in person and so requests. Attendance at
the Meeting will not in itself constitute revocation of the proxy.

     The Company will bear the cost of soliciting proxies in the form enclosed.
In addition to solicitation by mail, proxies may be solicited personally, or by
telephone, or by employees of the Company, without additional compensation for
such services. The Company may reimburse brokers holding Common Stock in their
names or in the names of their nominees for their expenses in sending proxy
material to the beneficial owners of such Common Stock.

NO PERSONS HAVE BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATIONS OTHER THAN THOSE CONTAINED OR INCORPORATED BY REFERENCE IN THIS
PROXY STATEMENT IN CONNECTION WITH THE SOLICITATION OF PROXIES AND, IF GIVEN OR
MADE, SUCH INFORMATION OR REPRESENTATIONS MUST NOT BE RELIED UPON AS HAVING BEEN
AUTHORIZED.

     Purpose; Merger Agreement. At the Meeting, Shareholders will consider and
vote upon a proposal to adopt an Agreement and Plan of Merger dated as of May
20, 1998 (the "Merger Agreement") between the Company and Holdings. The Merger
Agreement provides, subject to the approval of Shareholders at the Meeting, for
the merger of Holdings with and into the Company, with the Company being the
surviving corporation (the "Merger"). Approval of the Merger Agreement requires
the affirmative vote of the holders of two-thirds of the outstanding shares of
Common Stock. Since Holdings owns approximately 79% of the Common Stock,
adoption of the Merger Agreement is assured if Holdings votes in its favor.
Holdings has indicated its intention to vote in favor of the



                                      -2-
<PAGE>

Merger. Pursuant to the Merger Agreement, each outstanding share of Common Stock
(other than Common Stock held by the Company as treasury stock and Common Stock
held by Holdings), will be converted into the right to receive $11.00 per share
in cash (the "Merger Consideration"). Outstanding shares of common stock of
Holdings will be converted into the right to receive newly issued shares of
common stock of the Company. See "The Merger Agreement." A copy of the Merger
Agreement is attached to this Proxy Statement as Exhibit A.

     Since the Common Stock is designated as a national market system security
on the Nasdaq National Market, pursuant to Section 910 of the New York Business
Corporation Law (the "BCL"), appraisal rights will not be available to
shareholders of the Company. Accordingly, although a Shareholder who objects to
the Merger may vote against its adoption, since Holdings has indicated that it
will vote in favor of the Merger, the approval by Shareholders is assured and an
objecting Shareholder's available alternative may be limited to selling the
Shareholder's Common Stock before the Merger takes place.

     The Merger Agreement provides that as a condition to consummation of the
Merger, Holdings obtain the funds necessary to enable the Company to pay the
Merger Consideration. The Company has been informed by Holdings that Holdings
will amend its existing loan agreement with International Mezzanine Capital,
B.V. ("IMC"), an affiliate of Holdings dated as of March 19, 1998 to permit
Holdings to borrow funds sufficient to pay all or a portion of the Merger
Consideration and that the balance of the Merger Consideration (if any) will be
made available to Holdings by way of a capital contribution by Holdings' sole
shareholder, IMI. The aggregate amount of the Merger Consideration to be paid to
the Company's Shareholders is expected to be $6,900,377.

     Recent Stock Prices. On July 31, 1998, the high and low bid prices for the
Common Stock as reported on the Nasdaq National Market were $10 1/2 and $10 1/8,
respectively, and the last reported sale price was $10 1/8 per share. The last
reported trade of the Common Stock prior to the announcement of the Merger took
place on May 13, 1998 at a price of $9 1/4. The closing bid price of the
Company's Common Stock on May 19, 1998, the day before the Merger was announced
to the public was $9 1/4. See "Stock Prices and Suspension of Dividends."

     Recommendation of the Board of Directors. The Board of Directors of the
Company has determined that the Merger Agreement is fair to, and in the best
interests of, the Company and its Shareholders and has unanimously approved and
adopted the Merger Agreement. Certain members of the Board of Directors have
conflicts of interest. See "Interests of Certain Persons in the Merger;
Conflicts of Interest." See "Special Factors -- Acquisition; Purpose of the
Merger; Fairness Factors."

     Subsequent to its initial determination, the Board of Directors received
the opinion of Laidlaw & Co. as to the fairness of the Merger Consideration



                                      -3-
<PAGE>

and thereafter the Board unanimously confirmed its conclusion that the Merger
Agreement is fair to, and in the best interests of the Company and its
Shareholders. See "Special Factors--Laidlaw Review."

     Certain Results of the Merger. As a result of the Merger, Shareholders of
the Company will no longer have any continuing interest in the Company, the
Company's Common Stock will no longer be traded on the Nasdaq National Market
and the registration of the Company's Common Stock under the Securities Exchange
Act of 1934, as amended (the "Exchange Act") and the Company's reporting
obligations thereunder will be terminated. After giving effect to the Merger,
IMI, the sole shareholder of Holdings, will be the sole shareholder of the
Company.

     Interests of Certain Persons in the Merger. Messrs. Maarten D. Hemsley,
Robert M. Davies and Robert N. Haidinger (Directors of the Company) are
directors of Holdings. Messrs. James A. Read and Martin P. Dineen (Directors of
the Company) are officers and directors of Holdings. Mr. Haidinger is the
president of a company in which IMI, the sole shareholder of Holdings, has a
substantial interest. Menai Group, LLC and Bryanston Management Ltd (companies
which are wholly owned by Messrs. Davies and Hemsley, respectively) are partners
in IAC Acquisition Partners ("IAC Partners"), a partnership which provides
advisory and consulting services to Holdings. See "Interests of Certain Persons
in the Merger; Conflicts of Interest."

     Exchange of Certificates. If the Merger is consummated, the Company will
send instructions to Shareholders regarding the surrender of stock certificates.
SHAREHOLDERS SHOULD NOT SUBMIT ANY STOCK CERTIFICATES AT THE PRESENT TIME.

     Effective Time of the Merger. The Merger will become effective upon the
filing of a certificate of merger with the Secretary of State of New York (the
"Effective Time"). The filing will occur after all conditions to the Merger
contained in the Merger Agreement have been satisfied or waived. The Company and
Holdings anticipate that the Merger will be consummated as promptly as
practicable following the Meeting.

     Conditions to Consummation of the Merger. The respective obligations of the
Company and Holdings to consummate the Merger are subject to the satisfaction or
waiver at or prior to the Effective Time of the following conditions, among
others: (i) adoption of the Merger Agreement by the holders of the Company's
Common Stock; (ii) the absence of any statute, rule, injunction or order that
would prevent consummation of the Merger; (iii) the receipt of all required
authorizations, consents and approvals; (iv) Holdings having obtained funds or
arranged financing sufficient to enable the Company to pay the Merger
Consideration and (v) the performance of and compliance with all agreements and
obligations of the parties under the Merger Agreement.

     Termination of the Merger Agreement. The Merger Agreement may be terminated
and the Merger abandoned at any time prior to the Effective Time by the Board of
Directors of the Company or by Holdings. See "The Merger Agreement --
Termination."

Special Factors

     Acquisition; Purpose of the Merger; Fairness Factors. On March 19, 1998,
Holdings became the owner of 2,353,904 shares of the Common Stock, or
approximately 79% of the issued and outstanding shares of the Common Stock of
the Company. Holdings acquired 1,914,429 of such shares from Martin Hirschorn,
the Company's founder and, until May 1998, its Chief Executive Officer, and
439,475 of such shares from certain other management and institutional
shareholders, in each case for $11.00 per share. On March 19, 1998, Messrs. John
M. Handley, Michael W. Hirschorn, Arnold W. Kanarek and Jorgen Svendsen resigned
from the Board of Directors of the Company and on March 20, 1998 the remaining
Directors appointed Messrs. Robert M. Davies, Martin P. Dineen, Robert N.
Haidinger, Maarten D. Hemsley and James A. Read as Directors of the Company. See
"--Background of Change of Control."

     The Board of Directors, after Holdings' acquisition of 79% of the Common
Stock, considered the position, prospects and future of the Company generally
and as a company with public shareholders specifically and discussed such
matters with representatives of Holdings. For the reasons discussed below, the
Board of Directors determined in May of 1998 that it was not in the best
interests of the Company or its Shareholders for IAC to remain a company with
public shareholders and therefore the Board considered the proposed merger of
Holdings with and into the Company, and concluded that such Merger would be both
fair and in the best interests of the Company, its employees and both its
affiliated and unaffiliated Shareholders. Certain members of the Board of
Directors have conflicts of interests. See "Interests of Certain Persons in the
Merger; Conflicts of Interest." The same conclusion was reached by Holdings, and
by those members of the Board of Directors affiliated with Holdings, IMI, IMC
and IAC Partners. However, none of IMI, IMC or IAC Partners or their respective
executive officers, directors or partners made any recommendation in support of
or opposed to the Merger (other than the recommendation of the Merger as
directors by those persons who are also directors of the Company).

     The negative factors considered by the Board which weighed against
consummation of the Merger were the time and cost involved in effecting the
transaction and the fact that the Company would no longer be registered under
the Exchange Act, which would make it difficult for the Company to pursue
financing publicly. However, these countervailing factors were viewed as being
less significant than the ultimate benefits of the Merger to the Company and its
employees.

     The Board of Directors, which includes Martin Hirschorn and Frederic M.
Oran (the Company's Chief Executive Officer since May 1998), both of whom sold
all the



                                      -5-
<PAGE>

shares in the Company that they owned to Holdings in March 1998 at a price of
$11.00 per share, unanimously approved the Merger Agreement on May 20, 1998.
Certain members of the Board of Directors have conflicts of interests. See
"Interests of Certain Persons in the Merger; Conflicts of Interest." The Company
and Holdings entered into the Merger Agreement on May 20, 1998. In approving the
Merger Agreement and reaching its conclusions as to the fairness of the Merger
to unaffiliated Shareholders, the Board of Directors considered the following
factors in particular: (a) providing minority Shareholders with the same
opportunity to dispose of their shares at the price obtained from Holdings by
the Company's founder, management and certain institutional holders, which was
at a premium to the recent market price and reflected a "control premium"; (b)
the limited market for the Company's Common Stock as has existed in recent years
and the resulting limited ability of minority Shareholders to realize on their
investment in the Company; and (c) the urgent need for the Company's management
to take actions to reverse operating losses, which may, in the short term,
adversely affect the Company's operating results.

     Equivalent Price; Premium Over Market Price. In transactions with Holdings,
the founder and former Chief Executive Officer of the Company, Martin Hirschorn,
Frederic M. Oran, and other members of management and certain institutional
holders were able to receive $11.00 per share on their investment. This price
was negotiated on an arms-length basis between these unaffiliated parties after
giving effect to the recent trading range for the Common Stock and the Company's
financial position and prospects and recognizing a "control premium". See "--
Background of Change of Control." In considering the fairness of the Merger, the
Board of Directors gave particular weight to this factor.

     The average market price of the Common Stock for the period from March 19,
1998 (the date Holdings acquired its interest in the Company) to May 20, 1998
(the date the Merger Agreement was executed) was $9.71. The closing bid price
for the Common Stock on May 19, 1998, the day before the Merger was announced to
the public, was $9 1/4. The last reported trade of the Common Stock during that
period took place on May 13, 1998 at a price of $9 1/4. The Merger Consideration
of $11.00 per share represents a premium of 19% to such last reported trade. See
"Stock Prices and Suspension of Dividends." In considering the fairness of the
Merger to minority shareholders, the Board of Directors also gave significant
weight to this factor.

     Limited Trading Market. For several years there has a been a limited market
for the Company's Common Stock on the NASDAQ system. There are currently only
two market makers for the Common Stock. Additional purchases of some, but not
all of the outstanding shares of Common Stock by Holdings would only serve to
further contract the market for the Common Stock, thus resulting in an
increasingly illiquid minority.

     At July 31, 1998, the Company had approximately 600 holders of 627,307
shares of Common Stock, excluding shares held by Holdings. The Company
understands



                                      -6-
<PAGE>

that during the twelve months ended July 31, 1998, there were only 117 trades of
the Common Stock involving an aggregate of 97,365 shares of its Common Stock.

     Other factors considered by the Board of Directors in determining that the
Company and its employees would be better served by private ownership included:
1. the ongoing cost to the Company of regulatory compliance as a public company
without the benefit of having a ready market for its securities; 2. greater
operating flexibility in the management of the business to remedy recent adverse
operating results; and 3. disappointing results of operations which, as a result
of the Company's public status, become available to its competitors.

     Cost of Regulatory Compliance. The Company estimates that it spends
approximately $160,000 on an annual basis on costs solely related to being a
publicly-held entity, including legal, accounting, insurance, printing and
mailing costs. The Board considered the ongoing costs of remaining a public
company without the benefit of having a ready market for its securities in its
determination to approve the Merger.

     Operating Flexibility. The Board is of the opinion that the Merger would
enable management to concentrate their efforts on reversing the Company's
operating losses and improving long-term growth of its businesses and to make
business decisions and acquisitions free from the constraints of public
ownership, which the Board of Directors believes often places undue emphasis on
short-term considerations. The Board of Directors also believes that the
short-term effect of such restructuring efforts on the future market value of
Common Stock may be negative. The Board therefore believes that prospects for
achieving the necessary business turnaround would improve if it were no longer a
public company.

     Competitive Disadvantages. As a consequence of its publicly-held status,
the Company is required to file and make public detailed and periodic reports
about its operations and its financial status. The Company's detailed financial
reports disclose to the public (including the Company's competitors, customers,
suppliers and employee labor unions) operating losses which may be used to the
detriment of the Company by its competitors and in negotiations and dealings
with others. Certain of the Company's competitors are privately-owned companies,
not required to disclose publicly such sensitive financial details of their
operations. At the same time, competitors have the advantage of examining the
Company's financial statements. Those of the Company's competitors which are
publicly-held are either significantly larger, and engaged in a broader spectrum
of activities, or are subsidiaries of larger, diversified public companies whose
financial information is disclosed on a consolidated basis with other lines of
business. As to such competitors, required financial disclosures do not reveal
detailed information regarding the operations of those components directly
competitive with the Company. The Board of Directors believes that private
ownership of the Company would not only eliminate the requirement to disclose
results of operations but, as discussed above, would also provide management of
the Company with the



                                      -7-
<PAGE>

operating flexibility to focus on and improve the Company's results of
operations on a long-term basis. The value of such flexibility cannot be
quantified.

     Certain Results of Merger. As a result of the Merger, IMI will own all of
the outstanding equity interests of the Company (subject to agreements to grant
options in Common Stock to IAC Partners), so that IMI's interest in the Company,
including its future net earnings, will increase from approximately 79% to 100%
in return for the aggregate Merger Consideration of $6,900,377. According to the
terms of the Merger Agreement, each share of Common Stock (except treasury
shares and shares owned by Holdings) will be converted into the right to receive
the Merger Consideration of $11.00 per share. As a result, the Common Stock held
by existing Shareholders will no longer represent an equity interest in the
Company and will no longer share in future earnings or losses of the Company,
the risks associated with such earnings and losses, or the potential to realize
greater value in the event that strategic acquisitions, divestitures or other
extraordinary corporate transactions are pursued by the Company in the future.
Neither the Company nor, to the knowledge of the Company, Holdings now has any
such transactions under consideration. At September 30, 1997, the last quarterly
reporting date prior to the execution of a letter of intent between IAC Partners
and Martin Hirschorn for the sale of his shares, net book value of the Company
was approximately $41,009,000 or $13.77 per share. At March 31, 1998, the net
book value of the Company had declined to approximately $39,221,000, or $13.17
per share of Common Stock and at June 30, 1998 had further declined to
approximately $36,784,000 or $12.34 per share. Before giving effect to the
Merger, Holdings' 79% interest had a net book value to Holdings (that is, its
investment including the principal amount of the Loan but excluding
transactional expenses) of approximately $25,893,000, or $11.00 per share of
Common Stock. After giving effect to the Merger, Holdings will own all of the
outstanding shares of Common Stock of the Company and will have made an
investment, on a comparable basis, of approximately $32,793,000 or $11.00 per
share of pre-Merger Common Stock. The Company has reported net losses of $.78,
$.58 and $.41 per share for the quarters ended June 30 and March 31, 1998 and
the year ended December 31, 1997, respectively, and net income of $.12 per share
for the year ended December 31, 1996. The Company cannot predict when its recent
operating losses may be reversed.

     Following the Merger, it is anticipated that the registration of the Common
Stock under the Exchange Act will be terminated and that the Company will no
longer file reports under the Exchange Act. In addition, upon consummation of
the Merger, Holdings' obligation under an uncollateralized loan of approximately
$17 million from IMC, a subsidiary of IMI (the "Loan"), will become an
obligation of the Company's and the option held by IAC Partners to acquire 12%
of the common stock of Holdings will become an option to acquire 12% of the
Common Stock of the Company. See "-- Background of Change of Control."

     Federal Income Tax Considerations. The receipt of cash for Common Stock
pursuant to the Merger will be a taxable transaction for federal income tax
purposes under



                                      -8-
<PAGE>

the Code, and also may be a taxable transaction under applicable state, local
and other tax laws. In general, a Shareholder will recognize gain or loss equal
to the difference between the tax basis for the Common Stock held by such
Shareholder and the amount of cash received in exchange therefor. See "Certain
Federal Income Tax Consequences of the Merger."

     Board and Shareholder Approval; Independent Opinion. On May 20, 1998, the
Board of Directors of the Company approved the Merger unanimously. Certain
members of the Board of Directors have conflicts of interest. See "Interests of
Certain Persons in the Merger; Conflicts of Interest." No unaffiliated advisor
to the Board, any group of Directors or the Shareholders was retained prior to
May 20, 1998 for purposes of negotiating or reporting on the fairness of the
Merger. Subsequently, the Board engaged Laidlaw & Co. ("Laidlaw"), an investment
bank, to perform a financial analysis and to consider the fairness of the Merger
Consideration. See - "Laidlaw Review." In approving the Merger, the Board
considered the recent completion of Holdings' acquisition and its willingness to
effect the Merger at the same price per share being paid to minority
shareholders, which price Holdings and Mr. Hirschorn had negotiated at
arms-length. Holdings, IMI and IAC Partners considered the historic financial
results and position of the Company generally when the price between Holdings
and Mr. Hirschorn was agreed, made numerous inquiries to confirm the nature and
extent of the Company's assets and liabilities, and performed extensive
financial analyses. However, prior to approval of the Merger by the Board on May
20, 1998, no going concern or liquidation valuations were performed for the
Board. In considering the Merger, the Board of Directors did not undertake any
additional financial analyses to determine whether the Merger Consideration was
fair to unaffiliated shareholders. Based primarily on the fact that the Merger
Consideration of $11.00 per share represents a premium over the recent market
price of the Common Stock and that the price was agreed as a result of
arms-length negotiations between Holdings and Mr. Hirschorn, the Board of
Directors determined that additional financial analysis was not necessary to
reach a fairness determination. The Board of Directors also concluded that as a
result of the arms-length nature of the negotiations between Holdings and Mr.
Hirschorn and the fact that the price per share reflected a premium over the
market value of the Company, the process used in arriving at the Merger
Consideration was procedurally fair to all shareholders, including those not
affiliated with Holdings, IMI, IMC or IAC Partners. Certain members of the Board
of Directors have conflicts of interest. See "Interests of Certain Persons in
the Merger; Conflicts of Interest."

     Adoption of the Merger Agreement requires that it be approved by the
holders of two-thirds of the shares of Common Stock. Given the approximately 79%
interest of Holdings, the favorable vote of Holdings would assure such approval.
The Merger has not been structured to require the approval of a majority of
unaffiliated Shareholders.

     Although the net book value per share of Common Stock was $13.71 at March
31, 1998, the Board of Directors, Holdings, IMI, IMC and IAC Partners concluded


                                      -9-
<PAGE>

that recent net losses incurred by the Company of $.78, $.58 and $.41 per share
for the quarters ended June 30 and March 31, 1998 and the year ended December
31, 1997, respectively, and the lack of certainty as to when these losses may be
reversed, did not make book value a reliable indicator as to the going-concern
value of the Company. At June 30, 1998 the net book value per share of Common
Stock was $12.34.

     Although it is impracticable to assign a specific weight given to each of
the factors considered by the Board, the most heavily weighted factors in the
Board's decision were the premium being paid over the market price of the Common
Stock and the arm's length negotiation of the $11.00 price per share paid by
Holdings to Mr. Hirschorn. See "-- Acquisition; Purpose of the Merger; Fairness
Factors."

     Laidlaw Review. On July 22, 1998, the Company retained Laidlaw to perform a
financial analysis of the Merger and to consider the fairness of the Merger
Consideration previously approved by the Board of Directors, from the
perspective of shareholders not affiliated with Holdings, IMI, IMC or IAC
Partners. Laidlaw was engaged to provide an additional level of procedural
fairness to such unaffiliated holders. Laidlaw has no other relationship to the
Company, Holdings, IMI, IMC or IAC Partners.

     Laidlaw, founded in 1842, is a privately held, full service, international
investment bank which serves domestic and international corporations and
investors. Laidlaw's capabilities include asset management, institutional and
retail sales, trading, research and investment banking. As part of its
investment banking services, Laidlaw is engaged in public offerings and private
placements of both debt and equity securities. Additionally, Laidlaw offers its
clients a wide array of advisory services including merger and acquisitions,
divestitures, recapitalizations and fairness opinions.

     On July 31, 1998, Laidlaw delivered its conclusions (the "Laidlaw Review")
with respect to the Merger and the fairness of the Merger Consideration to the
Board of Directors of the Company.

     In summary, among other things, Laidlaw (i) reviewed certain publicly
available business and financial information, (ii) reviewed certain other
information, including financial forecasts provided by the Company, and (iii)
met with the Company's and Holdings' management to discuss the business and
prospects of the Company.

     Based on the above procedures Laidlaw concluded that the consideration of
$11.00 per share to be paid to the Company's shareholders was fair from a
financial point of view.

     On July 31, 1998 the Board of Directors met to consider the Laidlaw Review.
Based on the Laidlaw Review, as well as the various factors relating to the
Merger which it had previously considered, and further operating losses incurred
since the May 20, 1998 approval of the Merger, the Board of Directors
unanimously reapproved the Merger.



                                      -10-
<PAGE>

     A copy of the opinion of Laidlaw is available for inspection and copying at
the principal executive offices of the Company located at 1160 Commerce Avenue,
Bronx, New York during regular business hours (9:00 a.m. to 5:00 p.m.) by any
interested Shareholder or representative of a Shareholder who has been so
designated in writing.

     Background of Change of Control. In November 1997, IAC Partners approached
Mr. Hirschorn with a view toward arranging a purchase of Mr. Hirschorn's stock
in the Company. After a lengthy due diligence investigation, IAC Partners
negotiated a preliminary agreement with Mr. Hirschorn and IAC Partners
approached IMI, a Netherlands Antilles company engaged in the business of
investing in companies in the United States and Europe, about investing in the
Company.

     IMI decided to pursue an acquisition of the Common Stock of the Company
held by Mr. Hirschorn and certain other management and institutional
shareholders of the Company.

     IMI organized Holdings as a wholly-owned subsidiary of IMI to effect the
stock acquisition. In January 1998, Holdings entered into separate stock
purchase agreements with Mr. Hirschorn and the other selling Shareholders. On
March 19, 1998, Holdings and Mr. Hirschorn signed an amendment to the stock
purchase agreement between them waiving certain financial conditions to closing
and effecting a minor change in the number of shares being purchased. On that
date, Holdings acquired 2,353,904 shares of the Common Stock of the Company, or
approximately 79% of the issued and outstanding shares of the Common Stock of
the Company, 1,914,429 of which were purchased from Mr. Hirschorn and 439,475 of
which were purchased from the other selling Shareholders, all at a price of
$11.00 per share.

     In order to effect the acquisition, Holdings received an equity
contribution of approximately $10 million from IMI and an uncollaterized loan of
approximately $17 million from IMC, a subsidiary of IMI. Interest on the unpaid
principal amount of the Loan accrues at a rate per annum equal to LIBOR (as
defined in the IMC-Holdings loan agreement) plus 3.50 percent. The Loan matures
on March 19, 2000. The Company has been informed by Holdings that Holdings will
amend the IMC-Holdings loan agreement to allow for additional borrowings by
Holdings in order to enable the Company to pay all or a portion of the Merger
Consideration. If the Merger is consummated, the Loan, including any additional
borrowings, will become an obligation of the Company and its maturity could be
accelerated. No arrangements have been made to repay or refinance the Loan. IMI
will make a capital contribution to Holdings in an amount sufficient to pay the
balance, if any, of the Merger Consideration.

     Holdings and IAC Partners have agreed that IAC Partners would receive a due
diligence and consulting fee equal to 1.5% of the total consideration paid by
Holdings in the acquisition and would be granted an option to acquire 12% of the
common stock of



                                      -11-
<PAGE>

Holdings on a fully diluted basis, exercisable upon the sale by Holdings of all
or a majority of its interest in the Company, at an exercise price equal to the
net cost of IMI's equity investment in Holdings on a per share basis. Upon
consummation of the Merger, such option would become an option to acquire 12% of
the Common Stock of the Company on a fully diluted basis, exercisable upon the
sale by IMI of all or a majority of its interest in the Company. Holdings and
Messrs. Hemsley and Davies also expect to enter into a management agreement
pursuant to which Messrs. Hemsley and Davies will agree to provide certain
management services to Holdings relating to its investment in the Company,
including providing the services of Messrs. Hemsley and Davies as officers or
directors of the Company, if so requested.

     Immediately after the closing of the acquisition by Holdings, Messrs.
Handley, Michael Hirschorn, Kanarek and Svendsen resigned from the Board of
Directors of the Company and, on March 20, 1998, the remaining Directors
appointed Messrs. Davies, Dineen, Haidinger, Hemsley and Read to join Mr.
Hirschorn and Frederic Oran as members of the Board of Directors. On April 28,
1998, the Board of Directors accepted the resignations of Arnold Kanarek and
John Handley as senior officers of the Company, which resignations became
effective on May 1, 1998. Mr. Hirschorn also resigned as an executive officer of
the Company but remains the Chairman of the Board of Directors. On April 28,
1998, the Board of Directors elected Frederic Oran as President and Chief
Executive Officer of the Company, Robert N. Bertrand as Senior Vice President of
Finance and Administration and Secretary, and Robert A. Schmidt as Senior Vice
President of Marketing and Sales, all as of May 1, 1998.

Interests of Certain Persons in the Merger; Conflicts of Interest

     Messrs. Maarten D. Hemsley, Robert M. Davies and Robert N. Haidinger
(Directors of the Company) are directors of Holdings. Messrs. James A. Read and
Martin Dineen (Directors of the Company) are officers and directors of Holdings.
Messrs. Read and Dineen are affiliated with a private management group which is
the sole investment advisor to IMI, which owns 100% of the capital stock of
Holdings. As a principal of Mezzanine Management Ltd., an investment advisor to
IMI, Mr. Read may receive fees from IMI in connection with the provision of
services. Mr. Dineen is a salaried employee of Mezzanine Management Ltd. Through
companies owned by them, Messrs. Davies and Hemsley control IAC Partners which,
if requested, has agreed to provide advisory and consulting services to
Holdings. In addition, IAC Partners holds an option to acquire 12% of the common
stock of Holdings on a fully diluted basis. Upon consummation of the Merger,
such option would become an option to acquire 12% of the Common Stock of the
Company on a fully diluted basis. Through IAC Partners, Mr. Davies and Mr.
Hemsley have an indirect interest in 80% of such option and 80% to 100% of fees
for such advisory and consulting services depending on the type of services
provided. Mr. Haidinger is president of a company in which IMI has a substantial
interest. Although Mr. Haidinger may not have a conflict of interest that is
financial in nature, his relationship with IMI may be such that



                                      -12-
<PAGE>

scenarios may arise where the interests of the Company differ from those of IMI.
The nature of these conflicts is such that the Directors indicated may have an
interest in the Company beyond their status as directors. Any increase in the
value of the Company may benefit not only Holdings and persons affiliated or
associated with Holdings (including its directors), but also management and
employees of the Company.

Regulatory Approvals

     The Company does not believe that any federal or state requirements must be
complied with or that approval must be obtained in connection with the Merger,
other than filings required pursuant to federal securities laws and the filing
of the Certificate of Merger with the Secretary of State of New York and the
Secretary of State of Delaware.

Material Federal Income Tax Consequences of the Merger

     The receipt of cash for Common Stock pursuant to the Merger will be a
taxable transaction for federal income tax purposes under the Code, and also may
be a taxable transaction under applicable state, local and other tax laws.

     In general, a Shareholder will recognize gain or loss equal to the
difference between the tax basis for the Common Stock held by such stockholder
and the amount of cash received in exchange therefor. Such gain or loss will be
capital gain or loss if the Common Stock in the hands of the Shareholder is a
capital asset and, in the case of non-corporate Shareholders, generally will be
long-term gain or loss if the holding period for the Common Stock is more than
eighteen months prior to the Effective Date and mid-term gain or loss if the
holding period is more than one year but not more than eighteen months prior
thereto. In certain circumstances, Shareholders who are individuals may be
entitled to preferential treatment for long-term and mid-term capital gains;
however, the ability to offset capital losses against ordinary income is
limited. If the holding period is less than one year then the gain or loss will
be short term gain or loss.

     Long-term capital gains recognized by Shareholders who are individuals are
taxable at a maximum rate of 20% and mid-term capital gains are taxable at a
maximum rate of 28% (as compared with a maximum rate of 39.6% on ordinary
income). Corporations generally are subject to tax at a maximum rate of 35% on
both capital gains and ordinary income. The distinction between capital gain and
ordinary income may be relevant for certain other purposes, including the
taxpayer's ability to utilize capital loss carryovers to offset any gain
recognized.

     If a Shareholder has long-term, mid-term and short-term capital
transactions during the year, a multi-step netting process occurs. First, gains
and losses within each group are netted separately. The long-term capital gains,
if any, are offset by net short-term capital losses, if any. Short-term capital
losses are then applied to reduce any mid-term capital gain from the 28% group.
A net loss from the 20% group is used first to re-



                                      -13-
<PAGE>

duce net gain from the 28% group. A net loss in the 28% group may be used to
offset gain from the 20% group.

     If the result of combining all of the Shareholder's capital gains and
losses during the taxable year is a net capital gain, the full amount of such
gain will be included in the Shareholder's gross income. Any net capital gain
that is attributable to a particular rate group is taxed at that group's
marginal tax rate. In general, if the result of combining all such capital gains
and losses recognized during the taxable year is a net capital loss, a
Shareholder that is a corporation may not deduct any portion of such loss, and a
Shareholder that is not a corporation (such as an individual) may deduct such
loss only to the extent that it does not exceed $3,000 ($1,500 in the case of a
married individual filing a separate return), with the remainder available for
carryover into future taxable years.

     The foregoing discussion may not be applicable to Shareholders who acquired
their Common Stock pursuant to the exercise of options or other compensation
arrangements or who are not citizens or residents of the United States or who
are otherwise subject to special tax treatment under the Code.

     THE FOREGOING DISCUSSION IS THE COMPANY'S INTERPRETATION OF THE TAX
CONSEQUENCES OF THE MERGER AND IS BASED ON THE PROVISIONS OF THE CODE, TREASURY
REGULATIONS, RULINGS AND JUDICIAL DECISIONS NOW IN EFFECT, ALL OF WHICH ARE
SUBJECT TO CHANGE. ANY SUCH CHANGES MAY BE APPLIED RETROACTIVELY IN A MANNER
THAT COULD ADVERSELY AFFECT SHAREHOLDERS. EACH SHAREHOLDER SHOULD CONSULT ITS
OWN TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO IT, INCLUDING THE TAX
CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS OF THE RECEIPT OF
CASH FOR COMMON STOCK PURSUANT TO THE MERGER.

The Merger Agreement

     The following is a summary of the material terms of the Merger Agreement, a
copy of which is attached as Exhibit A to this Proxy Statement. Such summary is
qualified in its entirety by reference to the Merger Agreement.

     The Merger Agreement provides that, upon the terms and subject to the
conditions thereof, and in accordance with the BCL, at the Effective Time of the
Merger, Holdings shall be merged with and into the Company, with the Company
being the surviving corporation.

     The Merger Agreement provides that at the Effective Time, by virtue of the
Merger and without any action on the part of Holdings, the Company or the
holders of Common Stock:



                                      -14-
<PAGE>

          (a) Each share of Common Stock issued and outstanding immediately
     prior to the Effective Time (other than Common Stock owned by Holdings and
     Common Stock held by the Company as treasury stock) will be cancelled and
     will be converted automatically into the right to receive, in cash, from
     the Company an amount equal to $11.00 per share payable, without interest,
     to the holder of each such share, upon surrender of the certificate that
     formerly evidenced such share;

          (b) Each share of common stock of Holdings issued and outstanding
     immediately prior to the Effective Time will be cancelled and converted
     into a new share of common stock of the Company issued and outstanding, and
     no payment or distribution will be made with respect thereto; and

          (c) Each share of Common Stock held by Holdings or in the Company's
     treasury will be cancelled.

     Employees holding options under the Company's 1995 Stock Option Plan, as
amended, will be entitled, under the terms of the plan, to receive the
difference between the exercise price of each such option per share and $11.00
multiplied by the number of shares of Common Stock subject to such options.

     Under the Merger Agreement, the respective obligations of each party to
effect the Merger are subject to the satisfaction at or prior to the Effective
Time of the following conditions: (a) the Merger Agreement and the transactions
contemplated thereby have been approved and adopted by the affirmative vote of
the holders of a two-thirds of the Company's Common Stock; (b) there is no
statute, rule, injunction or order that would prevent consummation of the
Merger; (c) all required authorizations, consents and approvals have been
obtained; (d) Holdings having obtained funds or arranged financing sufficient to

parties under the Merger Agreement have been performed and complied with.

     Termination. The Merger Agreement may be terminated and the Merger and the
other transactions contemplated by the Merger Agreement may be abandoned at any
time prior to the Effective Time, notwithstanding any requisite approval and
adoption of the Merger Agreement and the transactions contemplated thereby by
the shareholders of the Company or by Holdings.

     Amendment and Waiver. The Merger Agreement may be amended in writing by the
parties thereto or by their respective Boards of Directors at any time prior to
the Effective Time. Except as otherwise provided by the Merger Agreement, any
party thereto may (i) extend the time for the performance of any obligation or
other act of any other party thereto, (ii) waive any inaccuracy in the
representations and warranties contained therein and (iii) waive compliance with
any agreement or condition contained therein.

Independent Auditors

     PriceWaterhouseCoopers LLP are the Company's independent auditors.
Representatives of PriceWaterhouseCoopers LLP are expected to be present at the
Meeting. They will have the opportunity to make a statement if they so desire
and are expected to be available to respond to appropriate questions.

Other Matters

     The Board of Directors knows of no other matters which will be presented
for consideration at the Meeting. However, if any other matter is properly
brought before the Meeting, it is the intention of the persons named in the
proxy forms to vote the Proxies in accordance with their best judgment.

Shareholder Proposals

     If the Merger is consummated, no public annual meetings of shareholders of
the Company will be held in the future. If the Merger is not consummated, and
because the date of any such meeting cannot currently be determined,
Shareholders will be informed (by press release or other means determined
reasonable by the Company) of the date of such meeting and the date that
Shareholder proposals for inclusion in the proxy material must be received by
the Company, which proposals must comply with the rules and regulations of the
Securities and Exchange Commission ("SEC") then in effect.

Compliance with Section 16(a) of the Securities Exchange Act of 1934

     Section 16(a) of the Exchange Act requires the Company's executive officers
and directors and persons who own more than 10 percent of the outstanding Common
Stock to file reports of ownership and changes in ownership with the SEC. Based
solely on reports and other information submitted by executive officers and
directors, the Company believes that during the year ended December 31, 1997,
and prior fiscal years, each of its executive officers, directors and persons
who owns more than 10 percent of the outstanding Common Stock filed all reports
required by Section 16(a).

Available Information

     The Company is subject to the informational requirements of the Exchange
Act and, in accordance therewith, files reports, proxy statements and other
information with the SEC. Such reports and other information may be inspected

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of
  Industrial Acoustics Company, Inc.:

     We have audited the consolidated financial statements and financial
statement schedule of INDUSTRIAL ACOUSTICS COMPANY, INC. and SUBSIDIARIES as
appearing in of this Proxy Statement. These financial statements and financial
statement schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits. We did not audit the financial
statements and financial statement schedule of Industrial Acoustics Company
Limited and Subsidiaries, a wholly owned subsidiary, which statements reflect
total assets of $17,104,000 and $18,690,000 at December 31, 1997 and 1996,
respectively, and total revenues of $19,310,000, $22,126,000 and $23,731,000 for
the years ended December 31, 1997, 1996 and 1995, respectively. Those statements
and schedule were audited by other auditors whose report has been furnished to
us, and our opinion, insofar as it relates to the amounts included for
Industrial Acoustics Company Limited and Subsidiaries, is based solely on the
report of the other auditors.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of the other auditors provide a
reasonable basis for our opinion.

     In our opinion, based on our audits and the report of other auditors, the
financial statements referred to above present fairly, in all material respects,
the consolidated financial position of Industrial Acoustics Company, Inc. and
Subsidiaries as of December 3l, 1997 and 1996, and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 3l,1997 in conformity with generally accepted accounting
principles. In addition, in our opinion, based on our audits and the report of
other auditors, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information required to be
included therein.

                   NOTES to CONSOLIDATED FINANCIAL STATEMENTS
            (Dollars and shares in thousands, except per share data)


NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation:

     The consolidated financial statements include the accounts of the Company
and its subsidiaries, all of which are wholly-owned. All significant
intercompany accounts and transactions have been eliminated.

Management's Use of Estimates:

     In conformity with generally accepted accounting principles, management
must make estimates and assumptions that affect the reported amounts of assets
and liabilities and disclosure of contingent assets and liabilities at the date
of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Cash Equivalents:

     The Company considers all highly liquid investments with an original
maturity of three months or less when purchased to be cash equivalents.

Inventories:

     Inventories are stated at the lower of cost (first-in, first-out method) or
market.

Long-term Construction Contracts:

     Estimated earnings on long-term construction type contracts are recognized
on the percentage-of-completion method, measured by the percentage of costs
incurred to date to estimated total costs for each contract. Periodic reviews of
estimated final revenues and costs during the terms of such contracts may result
in revisions of contract estimates, the effects of which are recognized in the
periods in which the revisions are determined. Provision for estimated losses on
uncompleted contracts are made in the period in which such losses are
determined.

     Included in receivables are retainages of $1,054 and $844 at December 31,
1997 and 1996, respectively. The Company expects to collect the open retainage
in 1998.

     Before tax operating results for 1997 and 1996 were decreased by $1,066 and
$2,250, net, due to changes in revenues and cost estimates on long-term
contracts.

Property, Plant and Equipment:

     Property, plant and equipment are carried at cost. Depreciation and
amortization of property, plant and equipment, including leased property, are
provided principally by the straight-line method based over the estimated useful
lives of the depreciable assets or the term of the related leases, if less. The
cost and accumulated depreciation or amortization of assets refined or sold are
removed from the respective accounts and any gain or loss is recognized in
operations.

Research and Development:

     Research and development expenditures, which are expensed as incurred,
amounted to $825, $944 and $872 in 1997, 1996 and 1995, respectively.

Short-Term Investments and Marketable Securities:

     The Company primarily invests its available funds into U.S. federal, state
and local government and corporate debt securities. The Company considers such
investments to be "available-for-sale" as defined by Statement of Financial
Accounting Standards ("SFAS") No. 115, "Accounting for certain Investments in
Debt and Equity Securities". SFAS 115 requires that the difference between the
carrying value and market value, as of the balance sheet date, of available
for-sale-investments be recorded as an adjustment to shareholders' equity.

     In the event of a decline in market value below carrying value ("Decline"),
which is other than temporary and resulting from factors other than changes in
interest rate, such Decline would be included in the operating results of the
Company in the period in which it occurs. In addition, if a Decline exists for
an investment which has been identified to be sold, such Decline would also be
included in operating results in the period in which it is identified to be
sold. During the year ended December 31, 1997, there were no Declines.

Earnings per Common Share Data:

     The Company adopted SFAS No. 128, "Earnings per Share," in 1997. As
required by the statement, the Company restated all prior-period per share data
presented. SFAS No. 128 requires presentation of both basic and diluted earnings
per share. Basic

              NOTES to CONSOLIDATED FINANCIAL STATEMENTS, continued

earnings per share are calculated based on the weighted average number of shares
of common stock outstanding during the reporting period. Diluted earnings per
share are calculated giving effect to all potentially dilutive common shares,
assuming such shares were outstanding during the reporting period.

     As required by SFAS No. 128, the Company has provided a reconciliation of
basic weighted average shares to diluted weighted average shares within the
table outlined below. The conversion of diluted shares has no impact on the
Company's operating results. Options to purchase 200,000 shares of common stock
were also outstanding at December 31, 1997 and 1995 but were not included in the
computation of diluted earnings per share because they would have had an
anti-dilutive effect on the earnings per share.

Concentration of Credit Risk:

     Financial instruments which potentially subject the Company to
concentrations of credit risk include cash, cash equivalents, short-term
investments, marketable securities and accounts receivable. The Company holds no
collateral for these financial instruments. The Company places its available
funds into government and corporate debt securities as well as investments with
financial institutions and, by policy, limits the amount of credit exposure to
any one issuer. Except for contracts with the United States Government,
concentration of credit risk with respect to accounts receivables are limited
due to a large diversified customer bass which is not concentrated in any one
geographic area. Some of the Company's contracts with the United States
Government have delivery schedules extending for more than one year. Under
applicable United States Government procedures, such contracts may be subject to
annual funding. Accordingly, there is some risk, even after a United States
Government contract has been awarded to the Company, that the necessary funding
for purposes of the contract may not be made available, in subsequent years, to
the relevant United States Government agency. United States Government contracts
may also be subject to cancellation, in which event, the Company would be
entitled to recover incurred costs on completed units, work in progress and
profits associated with such costs.

Recently Issued Accounting Standards:

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income" and SFAS No. 131, "Disclosure about Segments of an Enterprise and
Related Information." SFAS No. 130 establishes standards for reporting and
display of comprehensive income and its components (revenues, expenses, gains
and losses) in full set general purpose financial statements. SFAS No. 131
establishes accounting standards for the way that public business enterprises
report selected information about operating segments and requires that those
enterprises report selected information about operating segments in interim
financial reports issued to shareholders. SFAS No. 130 and SFAS No. 131 are
required to be adopted by 1998. The Company is currently evaluating the impact,
if any, of SFAS No. 130 and SFAS No. 131.

Foreign Currency Translation:

     All non-U.S. subsidiaries consider their local currencies to be their
functional currencies. Net assets of non-U.S. subsidiaries are translated into
U.S. dollars based on the current rates of exchange. Income and expense items
are translated at the average exchange rate for the year. The resulting
translation adjustments are recorded directly into a separate component of
shareholders' equity.

     Foreign currency transaction gains and losses result from the periodic
fluctuation in exchange rates, as measured at the respective balance sheet
dates, for transactions denominated in currencies other than the respective
functional currencies used by the Company and its subsidiaries. Such gains and
losses are included in the Company's operating results in the period in which
the exchange rate changes. The net foreign currency transaction (losses) gains
included in (loss) income before taxes for 1 997,1996 and 1995 were ($169), $211
and ($52), respectively. These net foreign currency translation (losses) gains
include ($149) and $366 in 1997and 1966, respectively, applicable to a U.S.
dollar demand loan payable to the Company by its subsidiary, Industrial
Acoustics Company Ltd (IAC Ltd).

Reclassification:

     Certain items in 1996 and 1995 have been reclassified to conform to the
1997 presentation.

NOTE B - SHORT-TERM INVESTMENTS AND MARKETABLE SECURITIES

     The Company considers its marketable securities to be "available-for-sale",
as defined by SFAS 115, and, accordingly, unrealized holding gains and losses
are excluded from operations and reported as a net amount in a separate
component of shareholders' equity.

     The following table summarizes the aggregate fair value of short-term
investments and marketable securities, gross unrealized holding gains and
losses, and the amortized cost basis of short term investments and marketable
securities at December 31, 1997:

NOTE F - EMPLOYEE BENEFIT PLANS

     The Company has a Defined Contribution Tax Deferred Savings Plan covering
all U.S. employees not covered by collective bargaining agreements. The
Company's elective contribution is allocated to employees based on a five year
average salary basis and is integrated with Social Security. In 1997, the
Company expensed $300 in connection with this Plan.

     The Company has a defined benefit pension plan in the United Kingdom
covering certain eligible employees. The Plan provides benefits based on years
of service and an employee's average compensation for the last three years of
employment before retirement. The Company's funding policy is to contribute
amounts sufficient to meet the minimum funding requirements. Assets of the plan
are comprised of a "with profits group" bond effected with an United Kingdom
assurance company.

   Pension costs include the following components:

     Assumptions used to calculate the actuarial present value of the projected
benefit obligation and the expected long-term return on assets for the defined
benefit plan are as follows:

                                                             1997       1996

    Rate of increase in future compensation levels.........  6.5%        6.5%

     The Company contributes to multi-employer pension plans on behalf of
employees who are members of collective bargaining units. Benefit and asset
information comparable to that shown above for the Company's plans are not
determinable. Under the Employee Retirement Income Security Act of 1974, as
amended, an employer upon withdrawal from a multi-employer plan is required to
continue funding its proportionate share of the plan's unfunded vested benefits.
The plan administrator has not provided the Company with information regarding
its proportionate share of the plan's unfunded vested benefits (for withdrawal
liability purposes); however, the Company has no immediate intention of
withdrawing from the plan. Expenditures incurred amounted to $122, $145 and $119
In 1997, 1996 and 1995, respectively.

     The Company has deferred compensation agreements with certain present and
past key officers, directors and employees ("participants"). The agreements
provide for the participants to receive defined amounts after reaching age 65.
The Company provides for the cost of the benefits payable under the agreements
over the participants' active employment. During the years ended December 31,
1997, 1996 and 1995, the Company incurred expenses related to these agreements
of $178, $202 and $164, respectively. As of December 31, 1997 and 1996, the
accrued liability totaled $1,339 and $1,367, respectively. The Company has
insured the lives of the participants to assist In the funding of this
liability.

     The building lease pertains to the New York manufacturing facility which
expires in 2019. However, the Company has entered into an agreement with the
landlord to purchase for $4,000 the approximately 72.500 square feet of
manufacturing space it now leases from the landlord.

     Future minimum payments, by yearand in the aggregate, under capital leases

NOTE H - STOCK OPTION PLAN

     On September 20, 1995, the Company adopted a stock option plan and granted
options to key employees to purchase 200,000 shares of common stock, the maximum
amount permitted under the plan, at $9.75 per share, the market value on the
date of grant. Options became exercisable after one year at the rate of 25% per
year for four consecutive years.

     In January 1997. the options granted in 1995 were rescinded and new options
to purchase another 200,000 shares of common stock were granted at $8.00 per
share, the market value on the date of grant. The options will become
exercisable after one year at the rate of 25% per year for four consecutive
years.

     Effective January 1, 1996, the Company adopted SFAS No. 123, "Accounting
for Stock-Based Compensation", which allows companies to measure compensation
cost in connection with employee stock compensation plans using a fair value
based method or to continue to use an intrinsic value based method. The Company
will continue to use the intrinsic value based method which generally does not
result in compensation cost. Had compensation cost been determined under the
fair value based method for the

     The fair value of each option is estimated on the date of grant using the
Black-Scholes option-pricing model with the following weighted average
assumptions used for the options granted in l995: -- dividend yield 1.17%;
expected volatility 40%; risk free interest rate of 6.33%; and expected lives of
6 years.
