                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and consolidated financial statements, including the notes thereto,
appearing elsewhere in this Prospectus. Unless otherwise indicated, all
information and data in this Prospectus assumes no exercise of the
Underwriters' over-allotment option.
 
                                  THE COMPANY
 
  The Company designs, manufactures and sells thermal management products and
connectors. The Company's thermal management products serve the microprocessor,
computer, consumer electronics, transportation and other industries, and its
connector products serve the defense, telecommunications, automotive and
aerospace industries.
 
  Thermal management products, principally heat sinks, remove excess heat
generated by electronic components within personal computers, power supplies,
stereo amplifiers and other electronic systems. The Company's largest thermal
management customers are Intel, IBM, General Electric and Pioneer Electronics.
The Company's Penguin Cooler line of heat sinks is specifically designed to
solve the thermal management problems of the rapidly growing microprocessor
market. As microprocessors become more powerful and are packaged in smaller
enclosures, the need for heat sinks increases. The Company believes that most
current 486 microprocessors and almost all Pentium and PowerPC microprocessors
require heat sinks. According to a Dataquest Incorporated market research
analysis published in June 1995, 5 million Pentium microprocessors were shipped
worldwide in 1994, an aggregate of 29 million Pentium and P6 (Pentium Pro)
microprocessors are projected to be shipped in 1995 and an aggregate of 61
million are projected to be shipped in 1996. The largest customers for Penguin
Coolers are Intel, IBM and Compaq.
 
  The Company also designs, manufactures and sells miniature and micro-
miniature connectors to meet rigid industrial and military specifications. Most
of the Company's connectors are customized products sold to niche markets.
These markets offer the Company an attractive revenue stream and significant
cash flow from operations. As the miniaturization of electronic systems
continues, the Company believes the demand for its miniature and micro-
miniature connectors will grow. The Company's largest connector customers are
Lockheed Martin, General Motors, Hughes Electronics, AT&T, Rockwell
International and Loral.
 
  In 1993, the composition of the Board of Directors of the Company changed.
Since then, the Company has grown through a combination of acquisitions and
internal growth. See "Business--History." The Company entered the thermal
management business in October 1993, when it acquired Wakefield Engineering,
Inc. from EG&G, Inc. In August 1994, the Company acquired Aham Tor Inc., a
manufacturer of heat sinks. In June 1995, the Company acquired Specialty
Extrusions, Ltd., a manufacturer of aluminum extrusions, the primary raw
material in heat sinks. In June 1994, the Company entered the niche-market
connector business when it acquired the Interconnect System Division of
Microdot Inc. Management believed that each acquisition was of a business that
was undervalued or undermanaged and was acquired for a favorable purchase
price.
 
  The Company's goal is to continue to grow internally and through
acquisitions. The Company intends to continue acquiring companies in its
current and related markets that it believes to be undervalued or undermanaged.
See "Use of Proceeds." To achieve internal growth, the Company intends to
continue providing its customers with strong value-added engineering and timely
product customization. The Company plans to purchase additional capital
equipment in order to increase capacity, lower manufacturing costs and further
improve customer response time.
 
  Alpha Technologies Group, Inc. was incorporated under its original corporate
name, Synercom Technology, Inc., in Texas in 1969, as a software company, and
was reincorporated in Delaware in 1983. The Company's corporate headquarters
are located at 750 Lexington Avenue, 27th Floor, New York, New York 10022, its
telephone number is (212) 446-5258, and its facsimile number is (212) 446-5290.
Unless the context otherwise requires, "Company" refers to Alpha Technologies
Group, Inc. and its subsidiaries, and "Management" refers to the management of
the Company.

                                  RISK FACTORS
 
  Prospective investors should carefully consider the following risk factors in
addition to the other information set forth in this Prospectus before making
any decision to invest in the Debentures.
 
MANAGEMENT OF GROWTH
 
  The Company's revenues have grown significantly during the past two years due
to several acquisitions. This growth has resulted in increased responsibilities
for Management. In addition, the Company is operating its manufacturing
facilities in Massachusetts near full capacity. The Company intends to address
these capacity constraints by expanding these facilities and acquiring related
operations or facilities. See "Use of Proceeds." Such expansion will further
increase the responsibilities of Management. There can be no assurance that the
Company will be able to manage its expansion. The failure to do so could
adversely affect the Company's financial position and results of operations.
 
FLUCTUATION IN QUARTERLY RESULTS
 
  The Company's quarterly operating results may vary significantly depending on
the types of products sold and the purchasing patterns of customers. Generally,
profit margins on connectors are higher than those on thermal management
products and profit margins on customized connectors are higher than those on
standard connectors. Connector sales and gross margins thereon can vary
significantly from period to period. In addition, the Company's backlog is not
indicative of future operating results, and quarterly sales and operating
results generally depend upon the volume and timing of, and ability to fill,
orders received within the quarter. These and other factors can materially
adversely affect the Company's operating results for one or more quarters. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition--Quarterly Comparisons."
 
FUTURE ACQUISITIONS; STRATEGIC INVESTMENTS
 
  All the Company's current revenues are derived from businesses acquired since
September 1993. See "Business--History." The Company intends to continue to
pursue acquisitions of businesses and product lines which the Company believes
have significant growth possibilities. See "Business--Strategy." Although the
Company's acquisitions have been profitable to date, there can be no assurance
that future acquisitions will be. In addition, the Company may take strategic
positions in marketable securities in connection with potential acquisitions or
other corporate transactions. If these acquisitions or transactions are not
undertaken or completed, the sale of these securities may result in investment
losses to the Company. See "Management's Discussion and Analysis of Results of
Operations and Financial Condition--Investment Income."
 
DEPENDENCE ON CERTAIN INDUSTRIES
 
  Sales of connectors to customers in the defense industry account for a
significant portion of connector sales. A decline in the defense budget for
programs which use the Company's products could adversely affect the Company's
operating results. In addition, sales of the Company's thermal management
products to customers in the microprocessor industry accounted for most of the
growth in sales of such products during the nine months ended July 30, 1995. A
decline in the growth of demand for high-performance microprocessors could
cause a decline in the growth of sales of the Company's thermal management
products and adversely affect its operating results. See "Business--Products"
and "Business--Customers."
 
QUALITY CONTROL STANDARDS
 
  The Company's products are incorporated into high technology products
manufactured by OEMs and, accordingly, must meet exacting specifications. A
substantial portion of the Company's OEM customers require the Company to
qualify as an approved supplier. In order to so qualify, the Company must
satisfy
 
                                       5
<PAGE>
 
stringent quality control standards and undergo extensive in-plant inspections
of its manufacturing processes, equipment and quality control systems. There
can be no assurance that the Company will be able to meet future customer
quality requirements. See "Business--Customers."
 
COMPETITION
 
  Supplying components for use in electronic products is highly competitive.
Competition is based on many factors, including product quality and
reliability, timely delivery, price and customer service. A number of companies
offer products and services similar to those offered by the Company. Several of
these competitors are divisions of larger companies with access to greater
financial and marketing resources. There can be no assurance that competitors
will not develop products that are superior to the Company's products. Further,
there can be no assurance that the Company will not experience additional price
competition that may adversely affect the Company's position and results of
operations. See "Business--Competition."
 
TECHNOLOGICAL CHANGES
 
  The markets for the Company's products are characterized by technological
advances, changes in customer requirements, product introductions and evolving
industry standards. The Company believes that its future success will depend,
in part, on its ability to continue to develop and market products and product
enhancements cost-effectively, which will require continued expenditures for
product engineering, sales and marketing. There can be no assurance that the
Company will be able to modify its products to meet customers' needs or that
the Company's product offerings will be accepted by its markets. See
"Business--Product Development" and "Business--Competition."
 
RAW MATERIALS COST
 
  The Company is dependent on aluminum for the production of its products.
Historically, the price for aluminum has experienced substantial volatility. A
significant cost increase for aluminum would have a material adverse effect on
the Company's results of operations. See "Management's Discussion and Analysis
of Results of Operations and Financial Condition--Gross Profit" and "Business--
Raw Materials."
 
DEPENDENCE UPON KEY MEMBERS OF MANAGEMENT AND OTHER EXECUTIVE OFFICERS
 
  The success of the Company is largely dependent on the efforts of Marshall D.
Butler, Chairman of the Board, Lawrence Butler, President and Chief Executive
Officer, Neal Castleman, President of Uni-Star, and Harry Chase, President of
Wakefield. The loss of their services could have a material adverse effect on
the Company's business and prospects. The Company has recently entered into a
three-year employment agreement with Mr. Lawrence Butler. See "Management" and
"Executive Compensation."
 
CONTROL BY MANAGEMENT AND CERTAIN DIRECTORS
 
  Members of Management and the Board of Directors, individually and through
partnerships controlled by certain members of Management and the Board,
beneficially own 1,570,123 shares of Common Stock in the aggregate,
representing 24.9% of the currently outstanding shares of Common Stock
(including options for 266,263 shares of Common Stock exercisable within 60
days, but not including options for 608,737 shares of Common Stock exercisable
after 60 days). By virtue of such ownership and their positions with the
Company, Marshall D. Butler, Lawrence Butler and Warren G. Lichtenstein may
have the practical ability to determine the election of all directors and
control the outcome of substantially all matters submitted to the Company's
stockholders. Such concentration of ownership could have the effect of making
it more difficult for a third party to acquire, or discourage a third party
from seeking to acquire, control of the Company. See "Security Ownership of
Certain Beneficial Owners and Management."
 
                                       6
<PAGE>
 
POTENTIAL CONFLICTS OF INTEREST
 
  Certain of the directors and executive officers of the Company are the
general partners of, and investors in, Steel Partners and Steel Partners II.
See "Security Ownership of Certain Beneficial Owners and Management." The
Company, Steel Partners and Steel Partners II have cooperated, and expect to
cooperate in the future, in making strategic investments intended to advance
the Company's acquisition strategy. Although they intend to cooperate in
achieving the Company's best interests, conflicts of interests may arise in the
future.
 
ENVIRONMENTAL CONSIDERATIONS
 
  The Company's manufacturing operations are subject to environmental laws and
regulations which govern waste water discharges, air emissions, the handling
and disposal of solid and hazardous wastes and the remediation of contamination
associated with the disposal of such wastes. See "Business--Environmental."
 
ABSENCE OF PUBLIC MARKET FOR THE DEBENTURES; VOLATILITY OF SECURITIES PRICES
 
  There is currently no public market for the Debentures. Although the
Debentures are expected to be traded on the SmallCap Market, there can be no
assurance that an active trading market will develop for the Debentures or, if
developed, that such market can be sustained. The Debentures may trade at a
discount from the initial offering price, depending upon prevailing interest
rates and other factors which may have a significant impact on the Debentures
and the Common Stock into which the Debentures are convertible. Such factors
could include the market price of similar securities, announcements of
technological innovations, new products or new customer relationships by the
Company or its competitors, regulatory developments, general economic and
political factors, as well as periodic fluctuations in financial results.
 
SUBORDINATION OF DEBENTURES; HOLDING COMPANY STRUCTURE
 
  The indebtedness evidenced by the Debentures is subordinate to the prior
payment when due of the principal of, and interest on, all Senior Indebtedness.
The Indenture does not limit the incurrence of additional Senior Indebtedness,
including trade debt incurred by the Company's subsidiaries or indebtedness on
borrowed funds. See "Description of Debentures--Subordination of Debentures."
The Company is a holding company which derives all its operating income from
its subsidiaries. The holders of the Debentures will have no direct claim
against such subsidiaries. The Company must rely upon dividends and other
payments from its subsidiaries to generate the funds necessary to meet its
obligations with respect to the Debentures. The ability of the Company's
subsidiaries to make such payments may be restricted by, among other things,
applicable laws or by the terms of agreements to which they may become party,
and may be subject to the claims of secured or other creditors of the
subsidiaries.
 
POTENTIAL ANTI-TAKEOVER EFFECTS OF DELAWARE LAW; POSSIBLE ISSUANCES OF
PREFERRED STOCK
 
  Certain provisions of Delaware law could delay, impede or make more difficult
a merger, tender offer or proxy contest involving the Company, even if such
events could be beneficial to the interests of the stockholders. Such
provisions could limit the price that certain investors might be willing to pay
in the future for shares of Common Stock. In addition, shares of preferred
stock can be issued by the Board of Directors without stockholder approval on
such terms as the Board may determine. The rights of the holders of Common
Stock will be subject to, and may be adversely affected by, the rights of the
holders of any preferred stock that may be issued in the future. Moreover,
although the ability to issue preferred stock may provide flexibility in
connection with possible acquisitions and other corporate purposes, such
issuance may make it more difficult for a third party to acquire, or may
discourage a third party from acquiring, a majority of the voting stock of the
Company. See "Description of Capital Stock."

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the Debentures in the
offering (the "Offering") are estimated to be $23,762,500 (or $27,371,875 if
the Underwriters' over-allotment option is exercised in full), after deducting
underwriting discounts and commissions and estimated offering expenses. The net
proceeds of the Offering will be applied to repay (i) the outstanding balance
(presently $5.6 million) under a revolving line of credit, due May 5, 1997,
bearing interest at a rate of 9 1/2% per annum on September 22, 1995 (computed
at .75% above the bank's corporate base rate), and (ii) the outstanding balance
(presently $1 million) under a revolving line of credit, due August 31, 1996,
bearing interest at a rate of 9 1/4% per annum on September 22, 1995 (computed
at .50% above the bank's prime rate). In addition, approximately $7 million of
the net proceeds will be used for capital expenditures, including expansion of
existing anodizing facilities, additional milling and machining centers,
production equipment, automated handling equipment and new computer systems.
The balance of the net proceeds, approximately $10 million, will be used to
fund increases in working capital and for general corporate purposes, including
strategic investments and acquisitions. Although the Company intends to pursue
acquisitions, there are no current agreements or understandings with respect to
any acquisitions.
 
  Pending its application as described above, the net proceeds of the Offering
will be invested in U.S. Treasury bills and other short-term investment grade,
interest-bearing instruments.
 
                          PRICE RANGE OF COMMON STOCK
 
  The Common Stock, $.03 par value ("Common Stock"), of the Company is quoted
on the National Market under the symbol "ATGI." The following table sets forth
for the periods indicated the range of the high and low sales prices of Common
Stock as reported on the National Market.

                                   DIVIDENDS
 
  The Company has paid no dividends on the Common Stock and it is anticipated
that no cash dividends will be paid in the forseeable future. The payment of
cash dividends will depend on the earnings of the Company, the Company's
capital requirements, restrictions in future loan agreements, if any, and
other factors considered relevant by the Board of Directors of the Company.

                     OF OPERATIONS AND FINANCIAL CONDITION
 
OVERVIEW
 
  The Company entered the electronic components business in October 1993. The
following table sets forth the significant acquisitions made by the Company:

October 1993............ Thermal management operations in Wakefield  Wakefield Engineering,
                         and Fall River, Massachusetts ("Wakefield") Inc. & Alutech, Inc.
June 1994............... Connector and related product operations in Interconnect Systems
                         South Pasadena, California,                 Division of Microdot Inc.
                         Montgomeryville, Pennsylvania and
                         Cincinnati, Ohio ("Uni-Star")
August 1994............. Thermal management operations in Temecula,  Aham Tor, Inc.
                         California ("Ahamtor")
June 1995............... Aluminum extrusion operations in Fullerton, Specialty Extrusions Ltd.
                         California ("Specialty")
</TABLE>
 
  Since their acquisition, Ahamtor has been operated as a division, and
Specialty has been operated as a subsidiary, of Wakefield.
 
  The results of operations acquired are included in the Company's consolidated
results of operations only since their respective acquisition dates. In
September 1994, the Company sold the assets and business of its Information
Solutions Segment ("ISS") and is no longer in the software business. The
consolidated financial statements of the Company report separately the net
assets, gain on the sale and results of operations of such discontinued
operation. Because fiscal 1993 only includes one week of continuing operations,
1993 results are not meaningful.

  Sales. Total sales for the nine months ended July 30, 1995 increased 140%
compared to total sales for the comparable period in fiscal 1994. During the
1995 period, thermal management sales increased 104% due to internal growth of
54% and Ahamtor sales from the date of acquisition. Internal growth was due to
higher sales of extruded heat sink products, primarily Penguin Coolers, related
to the rapid growth of the high-performance microprocessor market. The nine-
month period ended July 30, 1994 included only two months of connector sales
following the acquisition of Uni-Star on June 1, 1994. In those two months, the
Company had above average connector sales because it shipped products under
backorders existing at the time of acquisition.
 
  Sales in fiscal year 1994 were not comparable to those in fiscal year 1993
due to the acquisition of Wakefield in October 1993, Uni-Star in June 1994 and
Ahamtor in August 1994.
 
  Pro forma sales for the 1994 and 1995 periods were higher than actual sales
for the same periods due to the inclusion of acquired operations. Pro forma
sales for the nine months ended July 30, 1995 increased 27% compared to pro
forma sales for the comparable period in fiscal 1994 primarily due to
significant growth in sales of extruded heat sinks, primarily Penguin Coolers,
as well as moderate growth in connector sales.
 
  Gross Profit. The Company's gross profit percentage decreased for the nine
months ended July 30, 1995 compared to the same period in 1994 as a result of
(i) the inclusion in the 1995 period of Ahamtor, which has a lower gross profit
percentage than the Company's average, (ii) an increase in the cost of
aluminum, a portion of which could not be reflected in the sales price of the
Company's products, (iii) a significant increase in sales of Penguin Coolers,
which have a lower gross profit percentage than the Company's average, (iv) a
high gross profit contribution during the 1994 period from backorders existing
at the time of the acquisition of Uni-Star and (v) a change in the mix of
higher margin customized connector products versus lower margin standard
connector products sold. The gross profit percentage decrease was offset in
part by a more efficient use of capacity.
 
  Pro forma gross profit percentage for the nine months ended July 30, 1995 was
lower than actual gross profit percentage for the same period due to the
inclusion of Specialty, which has a significantly lower gross profit percentage
than the Company's average, as well as an increase in pro forma cost of sales
related to the increase in the depreciable basis of equipment resulting from
the proposed purchase of the minority interest of Uni-Star. Pro forma gross
profit percentage for the nine months ended July 31, 1994 and the fiscal year
1994 was lower than the actual gross profit percentage for the same periods due
to the lower gross profit percentages of Uni-Star and Ahamtor in the period
prior to their being acquired relative to actual results.
 
  Pro forma gross profit percentage for the nine months ended July 30, 1995
compared to that for the nine months ended July 31, 1994 decreased due to the
operating factors discussed above.
 
  Research and Development Expense. Research and development expense includes
the cost of enhancing existing products and, to a lesser extent, the cost of
developing new products. The increase for the nine months ended July 30, 1995
compared to the same period in fiscal 1994 was due to an increase in
engineering staff as well as new licensing costs for engineering software and
the purchase of related workstations. Pro forma research and development
expense as a percentage of sales was lower than actual expense for the
comparable periods due to the absence of research and development activities at
the acquired operations prior to their being acquired by the Company.
 
  Selling, General and Administrative Expense. The decrease in selling, general
and administrative expense as a percentage of sales for the nine months ended
July 30, 1995 compared to the same period of fiscal 1994 was primarily
attributable to increased sales without a proportionate increase in selling,
general and administrative expense. Pro forma selling, general and
administrative expense as a percentage of sales was lower than actual expense
for the comparable periods due to the very low operating expenses of Ahamtor
and Specialty.

  Investment Income. In the past, the Company held marketable securities for
both strategic and investment purposes. Securities held for investment purposes
are reflected at fair market value, and the gain or loss is reflected in
investment income. Securities held for strategic purposes are reflected at fair
market value with the unrealized gain or loss thereon reflected in
stockholders' equity. The gain or loss on such securities is reflected as
investment income only upon sale. Investment income for the nine months ended
July 30, 1995 included $36,000 of investment security gains and $206,000 of
gains on sales of strategic investment securities. In September 1995, the
Company adopted a policy precluding any equity investments other than for
strategic purposes. The Company currently has no marketable investment
securities.
 
  Interest Income (Net). Interest income, which was $292,000 for the nine
months ended July 30, 1995 and $139,000 for the nine months ended July 31,
1994, was earned on excess cash. Interest expense was $39,000 for the nine
months ended July 31, 1994 and $523,000 for the nine months ended July 30,
1995.
 
  Income Taxes. The Company's provision for income taxes was impacted
substantially by tax benefits from net operating loss carryforwards ("NOL
Carryforwards"). The Company's tax provision is summarized as follows (in
thousands):

  On November 1, 1993, the Company implemented Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("Statement 109").
On that date, the Company had NOL Carryforwards of $23,214,000, which resulted
in a tax benefit of $7,893,000 (34% of the NOL Carryforwards). In addition to
tax benefits related to NOL Carryforwards, the Company had net tax benefits of
$814,000 related to tax credits and $714,000 related to certain temporary
differences. The Company established a net deferred tax asset for the total of
the aforementioned tax benefits of $9,421,000. Due to the lack of taxable
income in several prior years and uncertainty regarding the utilization of NOL
Carryforwards, a valuation allowance equal to the net deferred tax asset was
established (the "Valuation Allowance").
 
  During fiscal 1994, the Company reversed $2,846,000 of the Valuation
Allowance. The reversal represented (a) tax benefits of (i) $1,807,000 (34% of
the $5,314,000 of NOL Carryforwards utilized that year) and (ii) $1,360,000
resulting from Management's estimate of probable future taxable income, offset
by (b) $321,000 related to the tax effects of temporary differences. For the
nine months ended July 30, 1995, the Company reversed $1,256,000 of the
Valuation Allowance. This reversal represented (a) tax benefits of (i) $872,000
(34% of the $3,287,000 of NOL Carryforwards utilized, less the portion of the
Valuation Allowance previously allocated to these NOL Carryforwards) and (ii)
$693,000 resulting from Management's estimate of future taxable income, offset
by (b) $309,000 related to the tax effects of temporary differences. These
reversals of the Valuation Allowance are reflected as income tax benefits in
the respective periods. The remaining Valuation Allowance of $5,319,000
(primarily relating to net operating losses of $14,613,000) will be reversed as
warranted by future profitable operations and Management's future estimates of
the realization of the deferred tax asset based on expected taxable income.

  On July 30, 1995, the Company had, for tax purposes, remaining NOL
Carryforwards of approximately $14,613,000 available to offset future taxable
income, and approximately $814,000 of unused investment and research and
development tax credits available to offset future Federal income taxes. The
NOL Carryforwards will expire from 2000 to 2008, and the tax credit
carryforwards will expire from 1995 to 2005. All carryforwards are subject to
review and possible adjustment by the Internal Revenue Service. In addition,
Section 382 of the Internal Revenue Code significantly limits the amount of NOL
Carryforwards usable by a corporation following a more than 50% change in
ownership of the corporation during a three-year period. It is possible that
subsequent transactions involving the Company's capital stock could result in
such a limitation.
 
  Minority Interest. The Company acquired 80% of Uni-Star in June 1994. The
Company is currently negotiating the purchase of the remaining interest for
approximately 365,000 shares of Common Stock. The Company estimates the market
value of these shares to be approximately $2.7 million (valued as "restricted
securities," as defined in Rule 144 under the Securities Act of 1933 (the
"Act"), subject to certain contractual voting and sale restrictions). Based
upon this estimate, the purchase will increase the basis of Uni-Star's assets
by $1,080,000 for financial statement purposes and thereby increase
depreciation and amortization expense by an estimate of $108,000 per year.
 
  Discontinued Operation. The Company sold its software product business in
September 1994. The purchase price was $4 million, of which $2 million was paid
at closing, $1 million was paid in January 1995 and the final $1 million was
paid in March 1995. An expense of approximately $800,000 was accrued,
principally representing lease payments and estimated costs that the Company
expected to incur on the space used by the disposed business, less estimated
payments that it expected to receive for subleasing the space. The Company
recognized a gain on the sale of $1,380,000, net of the $800,000 accrual,
income taxes and a reserve to cover contingencies.

QUARTERLY COMPARISONS
 
  The following table sets forth unaudited selected quarterly financial
information for the periods indicated. This information includes all
adjustments, consisting only of normal recurring accruals, that Management
considers necessary for a fair presentation of the data when read in
conjunction with the Consolidated Financial Statements and the notes thereto
included elsewhere herein. The results of operations for historical periods
may not necessarily be indicative of results for any future period. In the
first quarter of 1995, total sales decreased due to a decrease in connector
sales. Connector sales vary from period to period based on the purchasing
patterns of certain customers. In the first quarter of 1995, gross profit
percentage was lower than in the preceding three quarters due to the amount of
custom connector products sold in each quarter. The gross profit percentage of
connectors fluctuates based upon the mix of custom products, which have a
higher gross profit percentage, and standard products sold. Generally, the
gross profit percentage for connectors is higher than that for thermal
management products.

LIQUIDITY AND CAPITAL RESOURCES
 
  Funds for operations and purchases of capital equipment, businesses and stock
for the nine months ended July 30, 1995 were provided primarily from existing
cash and advances under the Wakefield loan agreement. The funds were used as
follows:
 
    (i) $1,130,000 were used to fund operating activities, primarily to
  increase accounts receivables and inventories, offset in part by amounts
  collected on notes receivable related to the sale of the software business.
  See Note 3 to Financial Statements;
 
    (ii) $2,560,000 were used to purchase Specialty and to retire existing
  Specialty debt;
 
    (iii) $3,168,000 were used to purchase equipment, including machines to
  add capacity and improve productivity in the manufacturing of extruded heat
  sinks, primarily Penguin Coolers, and to upgrade internal computer systems;
  and
 
    (iv) approximately $2,118,000 were used to purchase 391,155 shares of
  Common Stock pursuant to the Company's Common Stock repurchase plan. This
  repurchase program has been completed.
 
  In June 1994, Wakefield entered into a loan agreement which included a
revolving credit facility of up to $4 million, an equipment term loan of
$1,250,000 and an equipment credit facility of $600,000. In May 1995, Wakefield
amended this loan agreement to increase the revolving credit facility to $7
million and the equipment credit facility to $1,050,000, and to extend the term
of the revolving credit facility to May 5, 1997. In addition, Wakefield
borrowed $265,000 as an equipment term loan. Interest on the revolving credit
facility and equipment loans accrues at the bank's corporate base rate plus
 .75%. On September 22, 1995, the interest rate on the bank debt was 9 1/2% per
annum. The obligations under the loan agreement are secured by a first lien on
and assignment of the assets of Wakefield, excluding Specialty's assets. The
loan agreement includes various financial covenants which the Company was in
compliance with on July 30, 1995, the most recently ended fiscal quarter. On
September 22, 1995, $5,625,000 was outstanding under the revolving credit
facility.
 
  On August 31, 1995, Uni-Star entered into an accounts receivable loan
agreement which included a revolving credit commitment of up to $2.5 million.
Uni-Star also entered into an equipment term loan in the amount of $750,000
(from which $104,000 of preexisting debt was refinanced) and an equipment
acquisition facility of $300,000. The initial proceeds of $963,000 from the
revolving credit commitment and $646,000 net proceeds from the equipment term
loans were used to repay advances of $1,609,000 from the Company to Uni-Star.
The proceeds from the equipment acquisition facility may be used only for the
purchase of capital equipment. Interest on the funds advanced under the
revolving credit commitment ($1 million on September 22, 1995) accrues at the
bank's prime corporate rate plus .50% (9 1/4% per annum on September 22, 1995)
and interest on the equipment term loan accrues at the bank's prime rate plus
 .75% (9 1/2% per annum on September 22, 1995). The principal amount of the
equipment term loan is repayable in 48 equal monthly installments, beginning
October 1, 1995. All Uni-Star credit facilities are secured by a first lien and
assignment of substantially all Uni-Star's assets, including its accounts
receivable, inventory, equipment and general intangibles.
 
  The Company believes that the net proceeds of this Offering, together with
its currently available cash, anticipated cash flow from operations and
availability under credit facilities should be sufficient to satisfy its
current and planned operations for the next 12 to 18 months.

                                    BUSINESS
 
OVERVIEW
 
  The Company designs, manufactures and sells thermal management products and
connectors. The Company's thermal management products serve the microprocessor,
computer, consumer electronics, transportation and other industries, and its
connector products serve the defense, telecommunications, automotive and
aerospace industries.
 
  Thermal management products, principally heat sinks, remove excess heat
generated by electronic components within personal computers, power supplies,
stereo amplifiers and other electronic systems. The Company's largest thermal
management customers are Intel, IBM, General Electric and Pioneer Electronics.
The Company's Penguin Cooler line of heat sinks is specifically designed to
solve the thermal management problems of the rapidly growing microprocessor
market. As microprocessors become more powerful and are packaged in smaller
enclosures, the need for heat sinks increases. The Company believes that most
current 486 microprocessors and almost all Pentium and PowerPC microprocessors
require heat sinks. According to a Dataquest Incorporated market research
analysis published in June 1995, 5 million Pentium microprocessors were shipped
worldwide in 1994, an aggregate of 29 million Pentium and P6 (Pentium Pro)
microprocessors are projected to be shipped in 1995, and an aggregate of 61
million are projected to be shipped in 1996. The largest customers for Penguin
Coolers are Intel, IBM and Compaq.
 
  The Company also designs, manufactures and sells miniature and micro-
miniature connectors to meet rigid industrial and military specifications. Most
of the Company's connectors are customized products sold to niche markets.
These markets offer the Company an attractive revenue stream and significant
cash flow from operations. As the miniaturization of electronic systems
continues, the Company believes the demand for its miniature and micro-
miniature connectors will grow. The Company's largest connector customers are
Lockheed Martin, General Motors, Hughes Electronics, AT&T, Rockwell
International and Loral.
 
HISTORY
 
  In 1993, Marshall D. Butler, Frederic A. Heim and Warren G. Lichtenstein
joined the Board of Directors and Lawrence Butler became a consultant to the
Company. Subsequently, Lawrence Butler joined the Board and in 1995 became
President of the Company. Beginning in 1993, the Company embarked on a strategy
to acquire electronic component companies which were: (i) operating profitably,
(ii) offering products to rapidly growing markets or high-margin niche-markets,
and (iii) available at prices the Company believed to be attractive. The
directors believed that their collective experience, as well as the Company's
cash reserves and NOL Carryforwards, were advantages in pursuing this strategy.
Concurrently, the Company reduced expenses in its software business and
achieved profitability. Subsequently, the Company sold the software business.
The Company has made four significant acquisitions since September 1993, three
thermal management operations and one connector company. The aggregate cost of
the acquisitions (excluding the proposed acquisition of the minority interest
in Uni-Star) was $15 million paid in cash.
 
  The Company entered the thermal management business in October 1993 by
acquiring Wakefield from EG&G, Inc. These operations were profitable and had a
strong existing customer base. Using the business plan developed by the
existing management team, the Company invested heavily in product engineering,
inventory and capital equipment. Wakefield's management was given greater
autonomy to make pricing and market-related decisions. This resulted in a
significant increase in sales of thermal management products, especially
Penguin Coolers.
 
  In June 1994, the Company acquired an 80% interest in the connector
operations of Microdot Inc. Neal Castleman, the current President of Uni-Star
and an experienced manager in this market, acquired the remaining 20% interest.
At the time, Microdot Inc. was being operated under Chapter 11 of the
Bankruptcy Code. This acquisition was an opportunity to enter a high-margin,
niche-market business with relatively stable revenues at what the Company
believed to be a highly attractive price. The Company is currently negotiating
the purchase of Mr. Castleman's minority interest. See "Management's Discussion
and Analysis of Financial Results and Operations--Results of Actual and Pro
Forma Operations--Minority Interest."

<PAGE>
 
  In August 1994, the Company acquired Ahamtor, which designs, manufactures and
sells extruded aluminum heat sinks. Ahamtor, based in California, complemented
the Company's existing Massachusetts thermal management operations by enlarging
its market territory and broadening the Company's customer base for thermal
management products.
 
  In June 1995, the Company acquired a supplier of extruded aluminum, the
primary raw material for heat sinks, by purchasing Specialty. This acquisition
provided the Company with a supplier for a portion of its extruded aluminum
needs. Specialty sells most of its output to third party customers.
 
STRATEGY
 
  The Company's goals are to be the leading provider of thermal management
products and a profitable supplier of niche-market connectors. The Company
intends to achieve these goals by using the following strategies.
 
  Supply Thermal Management Solutions to Growing High Technology Markets. The
Company seeks to capitalize on selected growth segments of the high technology
sector by supplying thermal management solutions. Sales of the Company's
Penguin Cooler line of heat sinks, a thermal management component for Pentium
and PowerPC microprocessors, have grown in response to this expanding market.
  Acquire Businesses and Assets at Attractive Prices. The Company intends to
continue acquiring companies in its current and related markets that it
believes to be undervalued or undermanaged. See "Use of Proceeds" and
"Business--History."
 
  Invest in Value-Added Engineering and Product Development. The Company seeks
to offer its customers customized value-added products that meet their
individual needs. By maintaining a strong engineering capability, the Company
is able to provide products that meet customer specifications in a timely
manner. The Company does not expend resources in research areas that are not
directly related to customer needs, and its emphasis has been on product
engineering rather than on basic research.
 
  Invest Capital to Increase Capacity and Production Efficiencies. The Company
has experienced significant internal growth, particularly in its thermal
management business. It plans to increase capacity and improve manufacturing
efficiencies through expenditures for new equipment and additional facilities,
as well as through acquisitions. See "Use of Proceeds."
 
  Create Entrepreneurial Environment for Operating Management. The Company
gives its managers autonomy to make pricing and market-related decisions that
allows them to respond to customer needs and increase market share. In
addition, the Company provides incentives to managers of its operating
subsidiaries through performance bonuses and stock option programs.
 
PRODUCTS
 
 Thermal Management
 
  Thermal management products are designed to dissipate heat generated within
electronic components and systems. The Company designs, manufactures and sells
thermal management products which serve a variety of industries, including the
microprocessor, computer, consumer electronics, industrial control, medical
instrumentation, laser, power supply and conversion, telecommunication
equipment, transportation and welding equipment industries. Company customers
for thermal management products include leading original equipment
manufacturers ("OEMs") of electronic equipment such as IBM, Intel, General
Electric and Pioneer Electronics.
 
  The demand for thermal management products is growing. As published in
Electronic Buyers' News in February 1995, International Interconnect
Intelligence, a market research firm, estimates that the average annual
compound growth rate for thermal products for electronic applications will be
13% to 14% worldwide
 
                                       19
<PAGE>
 
for the ten-year period from 1990 to 2000, a jump from $2 billion to $6
billion, and sales of thermal management products to the digital electronics
industry are projected to grow even faster, from $95 million in 1993 to more
than $725 million by 1998 in North America. In addition, the introduction of
the Pentium, which uses up to 16 watts of electrical power, made thermal
management critical for proper performance and reliability. According to an
independent market research study published by ARS inc. in September 1994,
Pentium microprocessors are estimated to grow from less than 1% of the
microprocessor market in 1993 to over 27% in 1995 and 63% in 1997.
 
  The Company believes it has distinguished itself in its ability to design and
manufacture innovative thermal management products to meet the needs of this
rapidly growing market segment. The Company's Penguin Cooler line of heat sinks
is specifically designed to solve thermal management problems in high-
performance microprocessors, such as the Pentium. Sales of Penguin Coolers have
experienced considerable growth in the past year and are an increasingly
significant portion of the Company's sales.
 
  The Company's thermal management products include:
 
                               Heat sinks specifically designed for high-
  PENGUIN COOLERS              performance microprocessors and personal
                               computers. These are used to solve thermal
                               problems of Pentium and certain 486 and
                               PowerPC products. Other microprocessor-
                               specific products include fansink
                               assemblies (heat sinks with electric fans
                               attached to them) and plastic heat sinks.
 
  EXTRUDED HEAT SINKS          Heat sinks and heat sink assemblies
                               designed for high power industrial
                               applications, including transportation and
                               stereo amplifiers. Other products include
                               bonded fin heat sinks used by makers of
                               power supplies.
 
  LOW POWER HEAT SINKS         Heat sinks designed for heat dissipation in
                               power semiconductors, transistors,
                               rectifier, diodes and other electronic
                               components used in electronic applications.
                               Typically, these are smaller components
                               used on printed circuit boards.
 
  ACTIVE COOLING               These products use air or liquid to
  COMPONENTS                   dissipate heat. Air-to-air heat exchangers
                               use fans to exchange heat with cooler air
                               and are used in high-performance
                               telecommunications, military and aerospace
                               systems. Liquid cooling systems are used in
                               applications which require the removal of
                               significantly greater amounts of heat such
                               as mainframe computers.
 
  PRECISION COMPRESSION        These products are complete mounting clamp
   MOUNTING CLAMP              and heat sink assembly systems for proper
   SYSTEMS                     installation, compression and cooling of
                               high-power compression pack silicon-
                               controlled rectifiers.
 
  ACCESSORY PRODUCTS           The Company's accessories include high-
                               performance thermal compounds, adhesives,
                               interface materials, hardware and
                               installation tools and other accessories.
 
 Connector Products
 
  Connectors are electro-mechanical devices which permit electronic components
such as printed circuit boards, power supplies and peripherals to be attached
and separated. The Company designs, manufactures and sells high-reliability
miniature and micro-miniature connectors used in military-specification and
high-performance applications. The Company's products also include backpanels,
headers and automotive switches. The Company's connector products are typically
produced in small volumes for niche markets and are highly customized for the
user's specific requirements. Company customers for connectors include Lockheed
Martin, General Motors, AT&T, Hughes Electronics and Loral.
 
                                       20
<PAGE>
 
   Connectors are required in many applications and are used in a diverse group
of industries, including the military, aerospace, medical instrumentation and
telecommunication industries. As a result, the demand for connectors is
growing. Fleck Research estimated in their 1995 Outlook, that the connectors,
cable assemblies and backpanel market in North America was $10 billion in 1994
and is projected to grow by 9.1% to $10.9 billion in 1995. Furthermore,
significant increases in printed circuit board performance require connectors
to take more connection points off the board, and to accommodate more contacts
in smaller spaces. As a result, the Company believes the demand for miniature
and micro-miniature connectors will grow.
 
  The Company's connector products include:
 
  MICRO-MINIATURE              Connectors which are configured in one to
  RECTANGULAR CONNECTORS       four rows with up to 400 contacts and
                               designed for high reliability military and
                               commercial applications.
 
  COAXIAL CONNECTORS           Coaxial connectors are single contact
                               miniature and micro-miniature devices used
                               predominantly in high reliability
                               communications and control systems.
 
  CIRCULAR CONNECTORS          The Company produces numerous families of
                               circular connectors, including hermetic
                               connectors. Hermetic connectors are
                               designed and produced to be impervious to
                               liquids and gases and to function in severe
                               environmental areas such as jet engines and
                               various instrumentation and manufacturing
                               systems.
 
  BACKPANELS AND HEADERS       Backpanels are manufactured either as
                               aluminum or printed circuit card units for
                               use in control systems and avionics. The
                               Company also produces VME (an international
                               specification) backpanels and systems
                               enclosures containing backpanels. The
                               Company also provides automatic wire
                               wrapping services, which permit engineers
                               to test and de-bug prototype boards before
                               producing printed circuit cards.
 
  AUTOMOTIVE SWITCHES          The Company's automotive switches are used
                               for brake lights, door jams, cruise
                               control, neutral safety start, junction
                               blocks and other automotive uses.
 
  TELEPHONE MODULE PLUGS       Modular plugs are available in various
                               configurations for a host of telephone and
                               other applications.
 
CUSTOMERS
 
  The Company has established a broad base of over three thousand customers,
representing a wide range of industries. No single customer accounted for
greater than 10% of the Company's sales during its fiscal year 1994 or during
the nine months ended July 30, 1995. The electronics industry, especially the
high-performance microprocessor and personal computer markets, represents the
Company's fastest growing customer group. Sales of the Company's thermal
management products in the microprocessor industry accounted for most of the
growth of such sales in the nine months ended July 30, 1995. Generally, sales
of connectors to the defense industry account for approximately 50% of
connector sales.
 
  The Company's products are incorporated into high technology products
manufactured by OEMs and, accordingly, must meet exacting specifications. A
substantial portion of the Company's OEM customers require the Company to
qualify as an approved supplier. In order to so qualify, the Company must
satisfy stringent quality control standards and undergo extensive in-plant
inspections of its manufacturing processes, equipment and quality control
systems.
 
SALES, MARKETING, AND DISTRIBUTION
 
  The Company designs, manufactures and sells both standard and customized
products. The Company seeks to become a strategic supplier to its customers and
to differentiate itself from its competitors by offering
 
                                       21
<PAGE>
 
a higher level of service and technical sales support to its customers. The
Company has a team of trained technical applications engineers and technicians
who are dedicated to providing ongoing technical support. These engineers and
technicians develop application-related literature, provide answers to
customers' questions on the use and application of the Company's products and
provide field support to customers. In addition, the Company has entered into a
joint marketing relationship with Flomerics, the developer of FLOtherm, a
software used by engineers to design new thermal management products, to make
joint presentations at trade shows and for Flomerics to feature products
developed by the Company in its demonstrations. The Company believes the
technical services provided by its engineers and technicians are an important
factor in its sales and product development efforts.
 
  The Company sells its products through a network of independent contract
manufacturers' representatives and distributors. In North America, thermal
management products are marketed through a seven-person direct sales force, 18
sales representatives and 60 distributors, and connectors are marketed through
17 manufacturers' representatives supported by the Company's six-person product
sales force. Sales offices are located in Wakefield, Massachusetts; Temecula,
Fullerton and South Pasadena, California; Cincinnati, Ohio; and Colmar,
Pennsylvania. In international markets, the Company uses five manufacturers'
representatives and 19 international distributors. International sales of
connector products are supported by two Company facilities located in England
and France, which also assemble and sell micro-miniature connectors for the
European market. Overall, international sales were responsible for 6.4% of the
Company's revenues during the nine months ended July 30, 1995.
 
  In general, the Company's sales representatives and distributors have entered
into agreements that allow for termination by either party upon 30 to 90 days
notice. Generally, distributors are permitted to return a small portion of
products purchased by them during the term of the agreements and to return all
products (other than obsolete products) purchased by them upon termination by
the Company. The Company's distributors are generally not precluded from
marketing competitive products.
 
PRODUCT DEVELOPMENT
 
  The Company's product development strategy is focused on engineering
modifications of existing products in response to customer needs. The Company
does not focus on the development of entirely new products or materials. During
fiscal 1994, the Company spent $674,000 on product research and development,
and during the nine months ended July 30, 1995, it spent $838,000, primarily
for development of thermal management products. The Company believes that its
technical capabilities, in conjunction with collaborative efforts with
customers, will allow it to continue to introduce products responsively and
quickly.
 
  The Company is currently developing standard and custom heat sink assemblies
for next generation microprocessors, such as the P6 (Pentium Pro) and P7. In
addition, the Company plans to expand product offerings for many types of low
power heat sinks and to expand its collaboration programs with manufacturers of
alternative materials to achieve cost reduction and performance improvements
for thermal management components.
 
  The Company intends to continue developing new connector products by
modifying and enhancing its current products. In keeping with this strategy,
the Company is currently designing and developing its next generation micro-
miniature connector family, which it expects will quadruple connection capacity
in a given space. The Company expects these products to be ready for market in
1996.
 
COMPETITION
 
  The thermal management market is highly competitive. There are several
companies which compete directly with the Company in the thermal management
business and offer products and services similar to those offered by the
Company. Although no one competitor is dominant, there are four principal
competitors in the thermal management market, including the Company. The
Company's three major competitors are
 
                                       22
<PAGE>
 
Aavid Thermal Technologies, Inc., IERC, a division of Dynamics Corporation of
America, and Thermalloy, a division of Bowthorpe, plc. Two of the Company's
thermal management product competitors are divisions of larger corporations
and, as such, have significantly greater financial, marketing, and technical
resources than the Company. Additional competition comes from hundreds of small
machine shops located throughout the country.
 
  The connector industry is highly fragmented with competition drawn along very
specific product lines. The larger connector companies, which include AMP,
Molex, ITT and Labinal, are large multi-national companies. These firms have
financial, marketing and technical resources far greater than the Company's.
Typically, these firms manufacture mass market, large volume standardized
products which do not compete directly with the Company's product lines. The
Company's principal competition in its connector operations, comes from smaller
niche-oriented companies which, like the Company, focus on low volume
customized products. Occasionally, the Company competes with smaller divisions
of the larger firms. The Company's direct competitors include HCC and Deutsch
in the hermetic connector market, CTS's Fabritek division and Teradyne in the
backpanel and header market, and ITT's Cannon division and Labinal's Cinch
division in the miniature and micro-miniature connector market.
 
BACKLOG
 
  The Company's backlog as of July 30, 1995 was approximately $22 million
compared with $9.5 million on October 31, 1994. Backlog typically consists of
purchase orders scheduled for shipment within 60 days following the order date
for thermal management products and 90 days for connector products. The
Company's backlog at any time is not indicative of future revenue. The Company
has also entered into buying agreements with several customers for its
connectors, including Lockheed Martin, Raytheon and Rockwell International.
These buying agreements generally provide that, for a term of 18 months to two
years, a customer will purchase all its requirements, if any, for a particular
product from the Company for a fixed price.
 
PROPRIETARY RIGHTS
 
  The Company applies for patents with respect to its most significant
patentable developments. It owns six patents related to its thermal management
products which expire from 1997 to 2012, and it has eight patents pending. The
Company owns 11 patents related to its connector products. Management believes
that its competitive position is not dependent on patents and that patent
expirations will not materially adversely affect the Company's competitive
position.
 
RAW MATERIALS
 
  The principal raw material used in thermal management products is aluminum.
The principal raw materials used in connector products are aluminum, copper,
stainless steel and steel alloy. The Company also uses gold, plating chemicals,
plastics, bar metal and wire in its production of connectors. The price of raw
materials represents a significant portion of the sales price of the Company's
products. With the exception of a portion of the Company's extruded aluminum
needs supplied under a one-year fixed price contract, these prices are based
upon market prices at the time of purchase. Historically, the price of aluminum
has experienced substantial volatility. Although thermal management products
are generally shipped within 60 days, and connectors are generally shipped
within 90 days, of receipt of orders, increases in raw materials prices cannot
always be reflected in product sales price. All raw materials are readily
available from multiple suppliers at competitive prices. In addition, Specialty
supplies a portion of the Company's needs for extruded aluminum.
 
ENVIRONMENTAL
 
  The Company believes that it conducts its operations in substantial
compliance with applicable environmental requirements.
 
                                       23
<PAGE>
 
  The Company uses several metal finishing processes in conjunction with
manufacturing its products. Anodizing, a method of electro-charging aluminum
and coating it with chemicals to enhance appearance and improve corrosion
resistance, is used in manufacturing heat sinks and certain other thermal
management products. Anodizing is done by the Company at its Fall River,
Massachusetts facility. A waste-product of the anodizing process is removed
from the Fall River facility by licensed waste haulers. The Company's Temecula,
California thermal management facility utilizes fully licensed third party
vendors to anodize its products. The Company also uses plating in its connector
operations to improve the products' appearance, provide corrosion protection
and, in some cases, enhance conductivity. The Company's connector facilities in
South Pasadena, California and Cincinnati, Ohio include precious metal plating
operations. These operations generate small amounts of toxic waste, which are
removed from the facilities by licensed waste haulers.
 
  While the Company believes that it has all environmental permits necessary to
conduct its business and that its activities conform to current environmental
regulations, more stringent environmental regulations may be enacted in the
future, and there can be no assurance that the Company will not incur
significant costs in the future in complying with such regulations. Local
environmental agencies monitor the Company's operations for ongoing compliance
with environmental requirements, and the Company is required to correct any
violations revealed by such monitoring. Although the Company is periodically
subject to notices of violations with respect to environmental requirements, it
is not aware of any violations that would require the Company to incur material
costs.
 
EMPLOYEES
 
  On July 30, 1995, the Company had 707 employees (661 of whom were full time).
Its thermal management operations had 374 employees (358 of whom were full
time), all in domestic operations, and its connector operations had 316
employees in domestic operations (287 of whom were full time) and seven
resident outside the United States (all of whom were full time). In addition,
the Company had 10 corporate employees (nine of whom were full time). Employees
are not represented by a labor union. Management believes that employee
relations are excellent.

to, and qualified in its entirety by reference to, all the provisions of the

to, it is intended that such articles, sections or defined terms shall be
incorporated herein by reference.

Company, payment of interest may be made by check mailed to the address of the
person entitled thereto as it appears in the Debenture Register. All payments

clause (iv)) to all holders of Common Stock to the extent such distributions,
combined with (A) all such all-cash distributions made within the preceding 12
months in respect of which no adjustment has been made, plus (B) any cash and
the fair market value of other consideration payable in respect of any tender
offers by the Company or any of its subsidiaries for Common Stock concluded
within the preceding 12 months in respect of which no adjustment has been made,
exceeds 10% of the Company's market capitalization (being the product of the
then current market price of the Common Stock times the number of shares of
Common Stock then outstanding) on the record date for such distribution; and
(vi) the purchase of Common Stock pursuant to a tender offer made by the
Company or any of its subsidiaries to the extent that the aggregate
consideration, together with (X) any cash and the fair market value of any
other consideration payable in any other tender offer expiring within the 12
months preceding such tender offer in respect of which no adjustment has been
made, plus (Y) the aggregate amount of any such all-cash distributions referred
to in clause (v) above to all holders of Common Stock within the 12 months
preceding the expiration of such tender offer in respect of which no
adjustments have been made, exceeds 10% of the Company's market capitalization
on the expiration of such tender offer. (Section 12.04) In the case of certain
consolidations or mergers to which the Company is a party or the conveyance or
transfer of the properties and assets of the Company substantially as an
entirety, each Debenture then outstanding would, without the consent of any
Holders of Debentures, become convertible only into the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
conveyance or transfer by a holder of the number of shares of Common Stock into
which the Debenture might have been converted immediately prior to such
consolidation, merger, conveyance or transfer, assuming such holder of Common
Stock failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon the
consolidation, merger, conveyance or transfer (provided that if the kind or
amount of securities, cash or other property so receivable is not the same for
each non-electing share, the kind and amount so receivable by each non-electing
share shall be deemed to be the kind and amount so receivable per share by a
plurality of the non-electing shares). (Section 12.10)
 
SUBORDINATION OF DEBENTURES
 
  The Debentures will be subordinated and subject, to the extent and in the
manner set forth in the Indenture, to the prior payment in full of all Senior
Indebtedness. (Section 13.01) Senior Indebtedness is defined to include the
principal of, premium, if any, interest and other amounts due on any
indebtedness, whether now outstanding or hereafter created, incurred, assumed
or guaranteed by the Company, for money borrowed from others (including
obligations under capitalized leases or purchase money indebtedness) or in
connection with the acquisition by the Company or a Subsidiary of any other
business or entity, or in respect of letters of credit or bid, performance or
surety bonds issued for the account or on the credit of the Company or a
Subsidiary, and, in each case, all renewals, extensions and refundings thereof,
other than (i) any such indebtedness as to which, in the instrument creating or
evidencing the same, it is provided that such indebtedness is not superior in
right of payment to the Debentures, (ii) indebtedness of the Company to any
Affiliate and (iii) the Debentures. (Section 1.01) At July 30, 1995, the
Company had approximately $19,147,000 of outstanding indebtedness that would
have constituted Senior Indebtedness under the Indenture. The Indenture does
not limit the amount of Senior Indebtedness that the Company may incur.
 
  No payments of principal of, premium, if any, or interest on the Debentures
may be made and no Debentures may be redeemed, retired or purchased if the
Company is then in default in the payment of any
 
                                       31
<PAGE>
 
Senior Indebtedness or if at the time any other Event of Default under the
terms of any Senior Indebtedness exists permitting acceleration thereof. Upon
any payment or distribution of assets of the Company in the event of any
insolvency, reorganization, liquidation or similar proceeding, all Senior
Indebtedness must be repaid in full (including any interest thereon accruing
after the commencement of any proceeding) before the Holders will be entitled
to receive or retain any payment. If the Debentures are declared due and
payable before their Stated Maturity because of the occurrence of an Event of
Default, no payment may be made in respect of the Debentures unless and until
all Senior Indebtedness shall have been paid in full. (Section 13.02)
 
  By reason of such subordination, in the event of insolvency, creditors of the
Company who are holders of Senior Indebtedness may recover more, ratably, than
Holders, and creditors of the Company who are neither holders of Senior
Indebtedness nor Holders may recover less, ratably, than holders of Senior
Indebtedness and may recover more, ratably, than Holders.
 
OPTIONAL REDEMPTION
 
  The Debentures will be redeemable upon not less than 30 nor more than 60
days' notice by mail at any time, as a whole or in part, at the election of the
Company, at a Redemption Price equal to the percentage of the principal amount
set forth below if redeemed in the 12-month period beginning             of the
years indicated:

</TABLE>            
 
and thereafter at a Redemption Price equal to 100% of the principal amount,
with accrued interest to the Redemption Date (subject to the right of Holders
of record on Regular Record Dates to receive interest due on an Interest
Payment Date), provided that the Company may not redeem any Debentures prior to
            , 1998. (Sections 2.03, 11.01, 11.04, 11.05 and 11.06)
 
CERTAIN RIGHTS TO REQUIRE REPURCHASE OF DEBENTURES BY THE COMPANY
 
  In the event of any Change in Control (as defined below) of the Company
occurring after the date of issuance of the Debentures and on or prior to
Maturity, each Holder of Debentures will have the right, at the Holder's
option, to require the Company to repurchase all or any part of the Holder's
Debentures on the date (the "Repurchase Date") that is 75 days after the date
the Company gives notice of the Change in Control as described below at a price
(the "Repurchase Price") equal to 100% of the principal amount thereof,
together with accrued and unpaid interest to the Repurchase Date. (Section
14.01) On or prior to the Repurchase Date, the Company shall deposit with the
Trustee or a Paying Agent an amount of money sufficient to pay the Repurchase
Price of the Debentures which are to be repaid on the Repurchase Date. (Section
14.03) Neither the Board of Directors of the Company nor the Trustee, acting
alone or together, can modify or waive this required repurchase of the
Debentures.
 
  Failure by the Company to repurchase the Debentures when required under the
preceding paragraph will result in an Event of Default under the Indenture
whether or not such repurchase is permitted by the subordination provisions of
the Indenture. (Section 5.01)
 
  On or before the 15th day after the occurrence of a Change in Control, the
Company is obligated to mail to all Holders a notice of the event constituting
and the date of such Change in Control,
 
                                       32
<PAGE>
 
the Repurchase Date, the date by which the repurchase right must be exercised,
the Repurchase Price for Debentures, and the procedures which a Holder must
follow to exercise a repurchase right. To exercise the repurchase right, a
Holder of a Debenture must deliver, on or before the 10th day prior to the
Repurchase Date, written notice to the Company (or an agent designated by the
Company for such purpose) and to the Trustee of the Holder's exercise of such
right, together with the certificates evidencing the Debentures with respect to
which the right is being duly exercised, duly endorsed for transfer. (Section
14.02)
 
  A "Change in Control" shall occur when: (i) all or substantially all of the
Company's assets are sold as an entirety to any person or related group of
persons; (ii) there shall be consummated any consolidation or merger of the
Company (A) in which the Company is not the continuing or surviving corporation
(other than a consolidation or merger with a wholly-owned subsidiary of the
Company in which all shares of Common Stock outstanding immediately prior to
the effectiveness thereof are changed into or exchanged for the same
consideration) or (B) pursuant to which the Common Stock is converted into
cash, securities or other property, in each case other than a consolidation or
merger of the Company in which the holders of the Common Stock immediately
prior to the consolidation or merger have, directly or indirectly, at least a
majority of the common stock of the continuing or surviving corporation
immediately after such consolidation or merger, or (iii) any person, or any
persons acting together which would constitute a "group" for purposes of
Section 13(d) of the Exchange Act, together with any Affiliates thereof, shall
acquire beneficial ownership (as defined in Rule 13d-3 under the Exchange Act)
of at least 50% of the total voting power of all classes of capital stock of
the Company entitled to vote generally in the election of directors of the
Company. Notwithstanding clause (iii) of the foregoing definition, a Change in
Control shall not be deemed to have occurred solely by virtue of the Company,
any Subsidiary, any employee stock purchase plan, stock option plan or other
stock incentive plan or program, retirement plan or automatic dividend
reinvestment plan or any substantially similar plan of the Company or any
Subsidiary or any person holding securities of the Company for or pursuant to
the terms of any such employee benefit plan, filing or becoming obligated to
file a report under or in response to Schedule 13D or Schedule 14D-1 (or any
successor schedule, form or report) under the Exchange Act disclosing
beneficial ownership by it of shares or securities of the Company, whether in
excess of 50% or otherwise. (Section 14.05) A recapitalization or a leveraged
buyout or similar transaction involving members of Management or their
Affiliates will constitute a Change in Control if it meets the foregoing
definition.
 
  Notwithstanding the foregoing, a Change in Control as described above shall
not be deemed to have occurred if (i) the Current Market Price of the Common
Stock on the date of a Change in Control is at least equal to 105% of the
Conversion Price of the Debentures in effect immediately preceding the time of
such Change in Control, or (ii) all of the consideration (excluding cash
payments for fractional shares) in the transaction giving rise to such Change
in Control to the holders of Common Stock consists of shares of common stock
that are, or immediately upon issuance will be, listed on a national securities
exchange or quoted on the National Market, and as a result of such transaction
the Debentures become convertible solely into such common stock, or (iii) the
consideration in the transaction giving rise to such Change in Control to the
holders of Common Stock consists of cash or securities that are, or immediately
upon issuance will be, listed on a national securities exchange or quoted on
the National Market, or a combination or cash and such securities, and the
aggregate fair market value of such consideration (which, in the case of such
securities, shall be equal to the average of the daily Closing Price of such
securities during the 10 consecutive trading days commencing with the sixth
trading day following consummation of such transaction) is at least 105% of the
Conversion Price of the Debentures in effect on the date immediately preceding
the Closing Date of such transaction. (Section 14.05)
 
  There is no definition of the phrase "all or substantially all" as applied to
the Company's assets and used in the definition of Change in Control in the
Indenture, and there is no clear definition of such phrase under applicable
law. As a result of the uncertainty of the meaning of this phrase, in the event
the Company were to sell a significant amount of its assets, the Holders and
the Company may disagree over whether the sale gave rise to the right of
Holders to require the Company to repurchase the Debentures. In such case, the
 
                                       33
<PAGE>
 
Holders would likely not be able to require the Company to repurchase unless
and until the disagreement were resolved in favor of the Holders.
 
  The right to require the Company to repurchase Debentures as a result of the
occurrence of a Change in Control could create an Event of Default under Senior
Indebtedness, as a result of which any repurchase could, absent a waiver, be
blocked by the subordination provisions of the Debentures. See "Subordination
of Debentures". The Company's ability to pay cash to the Holders upon a
repurchase may be limited by certain financial covenants contained in the
Company's Senior Indebtedness.
 
  In the event a Change in Control occurs and the Holders exercise their rights
to require the Company to repurchase Debentures, the Company intends to comply
with applicable tender offer rules under the Exchange Act, including Rules 13e-
4 and 14e-1, as then in effect, with respect to any such purchase. The Change
in Control purchase feature of the Debentures may in certain circumstances make
more difficult or discourage a takeover of the Company and, thus, the removal
of incumbent Management. The Change in Control purchase feature, however, is
not the result of Management's knowledge of any specific effort to accumulate
shares of Common Stock or to obtain control of the Company by means of a
merger, tender offer, solicitation or otherwise, or part of a plan by
Management to adopt a series of anti-takeover provisions. Instead, the Change
in Control purchase feature is a standard term contained in other similar debt
offerings and the specific terms of this feature result from negotiations
between the Company and the Underwriters. Management has no present intention
to engage in a transaction involving a Change in Control.
 
  The foregoing provisions would not necessarily afford Holders protection in
the event of highly leveraged or other transactions involving the Company that
may adversely affect Holders.
 
SINKING FUND
 
  There will be no sinking fund established for the retirement of the
Debentures.
 
MODIFICATION OF THE INDENTURE
 
  Modifications and amendments of the Indenture may be made by the Company and
the Trustee with the consent of the Holders of two-thirds in principal amount
of the Outstanding Debentures provided that no such modification or amendment
may, without the consent of the Holder of each Outstanding Debenture affected
thereby, (i) change the stated maturity date of the principal of, or any
installment of interest on, the Debentures, (ii) reduce the principal amount
of, the rate of interest thereon, or any premium payable on, any Debentures,
(iii) change the place of payment where, or the coin or currency in which, any
Debenture or any payment or the interest thereon is payable, (iv) impair the
right to institute suit for the enforcement of any such payment when due, (v)
adversely affect the conversion rights of the Holders, (vi) modify the
provisions of the Indenture with respect to the subordination of the Debentures
in a manner adverse to the Holders, (vii) adversely affect the right to require
the Company to repurchase Debentures or (viii) reduce the percentage in
principal amount of Debentures the consent of whose Holders is required for
modification or amendment of the Indenture or for waiver of compliance with
certain provisions of the Indenture or for waiver of certain defaults. (Section
9.02)
 
EVENTS OF DEFAULT; NOTICE AND WAIVER
 
  The following are to be Events of Default: (i) default in the payment of any
interest, continued for 30 days; (ii) default in the payment of principal or
premium, if any, when due; (iii) default in the payment of the Repurchase Price
in respect of any Debenture on the Repurchase Date in accordance with the
Indenture; (iv) default in the performance of any other covenant continued for
60 days after written notice to the Company as provided in the Indenture; (v)
default in respect of indebtedness of the Company for money borrowed which
results in acceleration of the maturity of $1 million or more of indebtedness,
if such acceleration is not rescinded or indebtedness discharged within 30 days
after written notice to the Company
 
                                       34
<PAGE>
 
as provided in the Indenture; and (vi) certain events in bankruptcy, insolvency
or reorganization. (Section 5.01) If any Event of Default shall happen and be
continuing, the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Debentures may declare the Debentures due and payable
immediately. (Section 5.02) At any time after a declaration of acceleration
with respect to the Debentures has been made, but before a judgment or decree
based on acceleration has been obtained, the Holders of a majority in principal
amount of the Outstanding Debentures may, under certain circumstances, rescind
and annul such acceleration. (Section 5.02)
 
  No Holder will have any right to institute any proceeding with respect to the
Indenture or for any remedy under the Indenture unless (i) the Holder
previously has given to the Trustee written notice of a continuing Event of
Default, (ii) the Holders of not less than 25% in principal amount of the
Outstanding Debentures have made written request, and offered reasonable
indemnity, to the Trustee to institute proceedings as trustee, and (iii) within
60 days after such request, the Trustee has neither instituted such proceeding
nor received from the Holders of a majority in aggregate principal amount of
the Outstanding Debentures a direction inconsistent with the request. (Section
5.07)
 
  The Indenture will provide that the Trustee will be under no obligation,
subject to the duty of the Trustee during default to act with the required
standard of care, to exercise any of its rights or powers under the Indenture
at the request or direction of any of the Holders, unless such Holders shall
have offered to the Trustee reasonable indemnification. (Section 6.03) Subject
to such provisions for indemnification of the Trustee, the Holders of a
majority in principal amount of the Outstanding Debentures will have the right
to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee. (Section 5.12)
 
  The Holders of a majority in principal amount of the Outstanding Debentures
may on behalf of the Holders of all Debentures waive compliance by the Company
with certain restrictive provisions of the Indenture. (Section 10.07) The
Holders of a majority in principal amount of the Outstanding Debentures may on
behalf of the Holders of all Debentures waive certain past defaults except a
default in payment of the principal of (or premium if any) or interest on any
Debenture or in respect of a covenant or provision which under the Indenture
cannot be modified or amended without the consent of the Holder of each
Outstanding Debenture affected. (Section 5.13)
 
CONSOLIDATION, MERGER, CONVEYANCE OR TRANSFER
 
  The Indenture provides that the Company shall not consolidate with or merge
into any other corporation or convey or transfer its properties and assets
substantially as an entirety to any person, unless (i) any such successor
assumes the Company's obligations under the Debentures and the Indenture, (ii)
after giving effect thereto, no Event of Default shall have occurred and be
continuing and (iii) certain other conditions under the Indenture are met.
(Section 8.01) Upon any such consolidation or merger, or any such conveyance or
transfer of the properties and assets of the Company substantially as an
entirety, the successor corporation formed by such consolidation, or into which
the Company is merged, or to which such conveyance or transfer is made, shall
succeed to, and be substituted for, any may exercise every right and power of,
the Company under the Indenture with the same effect as if such successor
corporation had been named as the Company. The Company as the predecessor
corporation shall be relieved of all obligations and covenants under the
Indenture. (Section 8.02)
 
GOVERNING LAW
 
  The Indenture will provide that the Debentures will be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflicts of law.
 
THE TRUSTEE
 
                     will be the Trustee under the Indenture.

                          DESCRIPTION OF CAPITAL STOCK
 
COMMON STOCK
 
  The authorized capital stock of the Company includes 17 million shares of
Common Stock, par value $.03 per share. Holders of Common Stock have no
preemptive rights. The outstanding shares of Common Stock are fully paid and
non-assessable. Holders of Common Stock are entitled to dividends when, as and
if declared by the Board of Directors of the Company out of any funds legally
available to the Company for that purpose. A Holder will not be entitled to
receive dividends actually declared and paid, if any, with respect to the
Common Stock unless such holder has first exercised the conversion rights
associated with the Debentures, and then only to the extent such Holder has so
converted Debentures into shares of Common Stock.
 
  Holders of Common Stock are entitled to one vote per share held of record
with respect to all matters submitted to a vote of the stockholders. There is
no cumulative voting for the election of directors, who are elected annually to
one-year terms.
 
PREFERRED STOCK
 
  The Company is authorized to issue 180,000 shares of Preferred Stock, par
value $100 per share, and to establish and issue shares of Preferred Stock in
series and to fix, determine and vary the voting rights, designations,
preferences, qualifications, privileges, options, conversion rights and other
special rights of each series of Preferred Stock. As of the date of this
Prospectus no shares of Preferred Stock were issued and outstanding.
 
CERTAIN PROVISIONS OF DELAWARE LAW
 
  The Company is subject to Section 203 of (the "DGCL"), which prohibits a
Delaware corporation from engaging in a wide range of specified transactions
with any interested stockholder, defined to include, among others, any person
or entity who in the previous three years obtained 15% or more of any class or
series of stock entitled to vote in the election of directors, unless, among
other exceptions, the transaction is approved by (i) the Board of Directors
prior to the date the interested stockholder obtained such status or (ii) the
holders of two-thirds of the outstanding shares of each class or series owned
by the interested stockholder.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  Limitation of Liability. Pursuant to the DGCL, the Company has adopted
provisions in its Certificate of Incorporation which eliminate the personal
liability of its directors and officers to the Company and its stockholders for
monetary damages for breach of the directors' fiduciary duties in certain
circumstances and which authorize the Company to indemnify its directors,
officers and other agents, by bylaw, agreement or otherwise, to the fullest
extent permitted by law. Generally, a director will be liable for monetary
damages only for a breach of the duty of loyalty, a failure to act in good
faith, intentional misconduct, a knowing violation of law, an improper personal
benefit, or an illegal dividend or stock repurchase, but not for negligence or
gross negligence in satisfying the duty of care. The Company's Bylaws require
the Company to indemnify its directors, officers, employees and other agents to
the fullest extent permitted by law. Generally, a director will be entitled to
be indemnified against a claim if a majority of the directors who are not
parties, independent legal counsel, or the stockholders determines that the
director acted in good faith and in a manner he or she reasonably believed to
be in, or not opposed to, the best interests of the Company and, with respect
to a criminal action, had no reasonable cause to believe his or her conduct was
unlawful; and his or her expenses may be advanced by the Company if the
director undertakes to reimburse them if it is ultimately determined that he or
she was not entitled to indemnification.
 
  Indemnification Agreements. The Company has entered into an indemnification
agreement with each of its officers and directors. The agreements provide that
in the event any such executive officer or director, is or becomes a party or a
witness or other participant in any threatened, pending or completed action,
suit or proceeding (an "Action") relating to the fact that such person is or
was a director, officer, employee or agent
 
                                       36
<PAGE>
 
of the Company, or is or was serving at the request of the Company as a
director, officer, employee, trustee, agent or fiduciary of another
corporation, partnership, joint venture, employee benefit plan, trust or other
enterprise, the Company shall indemnify such person to the fullest extent or
permitted by the DGCL. In addition, the agreement provides that all reasonable
expenses (including legal fees) incurred by any such person shall be paid by
the Company in advance of the final disposition of any Action.
 
  Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission (the
"Commission") such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of
the Company in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the Company will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issuer.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is Bank of Boston, P.O.
Box 644, Boston, Massachusetts 02102. Its telephone number is (617) 575-2000.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a discussion of certain anticipated U.S. Federal income tax
consequences of the purchase, ownership and disposition of the Debentures as of
the date hereof. It deals only with the Debentures held as capital assets by
initial holders that are United States holders, and does not deal with special
situations, such as those of foreign persons, dealers in securities, financial
institutions, life insurance companies, holders whose "functional currency" is
not the U.S. dollar, or certain "straddle" or hedging transactions. The Federal
income tax considerations set forth below are based upon the Internal Revenue
Code of 1986, as amended (the "Code") and regulations, rulings and judicial
decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked or modified so as to result in Federal income tax
consequences different from those discussed below. PROSPECTIVE INVESTORS ARE
URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE PARTICULAR TAX CONSEQUENCES
OF PURCHASING, HOLDING AND DISPOSING OF THE DEBENTURES, INCLUDING THE TAX
CONSEQUENCES ARISING UNDER ANY STATE, LOCAL OR FOREIGN LAWS.
 
  A holder will not recognize gain or loss upon conversion of the Debentures
solely into Common Stock (except with respect to cash received in lieu of
fractional shares). The holder's basis in the Common Stock received on
conversion will be the same as the holder's adjusted tax basis in the
Debentures at the time of conversion, and the holding period for the Common
Stock received on conversion will include the holding period of the Debentures
that were converted.
 
  The Conversion Price is subject to adjustment under certain circumstances.
Under Section 305 of the Code and the treasury regulations issued thereunder,
adjustments or the failure to make such adjustments to the Conversion Price may
result in a taxable constructive distribution to the holders of Debentures,
resulting in ordinary income (subject to a possible dividends received
deduction in the case of corporate holders) to the extent of the Company's
current or accumulated earnings and profits if, and to the extent that, certain
adjustments in the Conversion Price may occur in limited circumstances
(particularly an adjustment to reflect a taxable dividend to holders of Common
Stock) increase the proportionate interest of a holder of a Debenture
convertible into fully diluted Common Stock, whether or not the holders ever
convert the Debentures. Generally, a holder's tax basis in a Debenture will be
increased by the amount of any such constructive dividend.

                                  UNDERWRITING
 
  The Underwriters named below (the "Underwriters") have severally agreed,
subject to the terms and conditions set forth in the Underwriting Agreement, to
purchase from the Company the principal amount of Debentures indicated below

       NOTES TO PRO FORMA CONSOLIDATED STATEMENTS OF INCOME--(CONTINUED)
 
  (b) Adjusted to eliminate the sales by Specialty to Ahamtor.
 
  (c) Adjusted to reduce (i) depreciation expense based on the difference
between the expense recorded by the acquired operation and the expense computed
based on the purchase price allocated to manufacturing equipment and (ii) cost
of sales related to sales by Specialty to Ahamtor. In addition, adjusted to
reflect the increase in the depreciable basis of the manufacturing equipment
due to the proposed purchase of the minority interest in Uni-Star.
 
  (d) Adjusted to reflect the amortization expense of goodwill which was
attributable to the excess of cost over the net assets of the companies
acquired using a straight line basis of 15 years. In addition, adjusted to
reflect amortization expense of non-compete agreements entered into related to
the purchase of Ahamtor.
 
  (e) Adjusted to reduce interest income or incur interest expense on funds
used to acquire companies.
 
  (f) Adjusted to reflect the issuance of 365,000 shares of the common stock of
the Company in conjunction with the proposed purchase of the 20% minority
interest in Uni-Star.
 
  (g) Adjusted to reflect the provision (benefit) for income taxes which would
have been required on the pro forma income from continuing operations before
income taxes and minority interest.
 
  (h) Adjusted to reverse the minority interest in subsidiary earnings, which
interest the Company is currently negotiating the purchase of.
 
  (i) The pro forma information provided above does not reflect adjustments for
the proposed offering of debentures.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and Board of Directors of
 Alpha Technologies Group, Inc.
 
  We have audited the accompanying consolidated balance sheets of Alpha
Technologies Group, Inc., (a Delaware corporation) and subsidiaries as of
October 31, 1994 and July 30, 1995, and the related consolidated statements of
income, stockholders' equity and cash flows for each of the two years in the
period ended October 31, 1994 and for the nine months ended July 30, 1995.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
  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 provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Alpha Technologies Group, Inc.
and subsidiaries as of October 31, 1994 and July 30, 1995, and the results of
their operations and their cash flows for each of the two years in the period

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of Alpha
Technologies Group, Inc. ("Alpha" or the "Company") (formerly Synercom
Technology, Inc.) and its wholly- and majority-owned subsidiaries. All material
intercompany transactions and balances have been eliminated. Certain
information in the prior years financial statements has been reclassified to
conform to the current presentation. As more fully described in Note 3, the
discontinued operation, the Information Solutions Segment ("ISS"), was
deconsolidated and fiscal 1993 financial statements have been restated
accordingly.
 
  The Company designs, manufactures and sells thermal management products and
connectors. Thermal management products serve the microprocessor, computer,
consumer electronics, transportation and other industries. Connector products
serve the defense, telecommunications, automotive and aerospace industries.
 
 Revenue Recognition
 
  Revenue from product sales is generally recognized upon shipment to the
customer.

  Available-for-Sale Securities-- These securities are stated at cost adjusted
for market value fluctuations. Unrealized gains and losses created by changes
in the market values of these securities are recognized as an adjustment to and
are reported as a separate component of stockholders' equity, net of tax. The
specific identification method is used in determining realized gains and losses
from the sale of securities.
 
  Trading Securities-- These securities are carried at market value. Realized
and unrealized gains and losses are recognized currently in investment income.
The specific identification method is used in determining gains and losses.
 
 Inventories
 
  Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out method.
 
 Property and Equipment
 
  The cost of property and equipment is depreciated using the straight-line
method for financial reporting purposes over the estimated useful lives of such
assets, ranging from three to ten years. Leasehold improvements are amortized
on a straight-line basis over the related lease term.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Goodwill
 
  Goodwill represents the excess of cost over fair value of net assets acquired
and is being amortized over 15 years using the straight-line method. The
accumulated amortization on October 31, 1994 and July 30, 1995 was
approximately $6,500 and $119,500, respectively. Amortization expense of
approximately $6,500 and $113,000 was recorded in fiscal 1994 and the nine
months ended July 30, 1995, respectively.
 
 Income Taxes
 
  The Company adopted Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes," ("Statement 109") on November 1, 1993. Under the
asset and liability method of Statement 109, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. Deferred tax assets and
liabilities are measured using current enacted tax rates. Under Statement 109,
the effect on deferred tax assets and liabilities of a change in tax rates is
recognized in the results of operations in the period that includes the
enactment date. Income taxes were accounted for in compliance with APB Opinion
No. 11--Accounting for Income Taxes; therefore, the tax benefit of net
operating loss carryforwards for fiscal 1993 was classified as an extraordinary
credit.
 
 Cash Flows
 
  Cash equivalents are defined as short-term, highly liquid investments with
maturities of less than 90 days that are readily convertible to known amounts
of cash. During fiscal 1994 and the nine months ended July 30, 1995, taxes
amounting to approximately $16,000 and $724,000, respectively, were paid.
Interest payments in fiscal 1994 and the nine months ended July 30, 1995
amounted to approximately $116,000 and $479,000, respectively.
 
 Foreign Currency Translation
 
  Assets and liabilities of the Company's foreign operations are translated
into U. S. dollars at the current exchange rate in effect at the balance sheet
date, and revenues and expenses are translated at the average exchange rate for
the period in accordance with Statement of Financial Accounting Standards No.
52, "Foreign Currency Translation". Resulting translation adjustments are
reported as a separate component of shareholders' equity.
 
 Fiscal Year
 
  For fiscal 1995, the Company adopted a 52/53 week fiscal calendar ending on
the last Sunday of October, therefore the first nine month period for fiscal
1995 ended on July 30, 1995. The comparable period in fiscal 1994 ended July
31, 1994. The nine month periods for fiscal 1995 and fiscal 1994 include 39
weeks of operations.
 
2. ACQUISITIONS
 
  Effective October 22, 1993, the Company, through a newly-organized, wholly-
owned subsidiary, acquired substantially all of the assets and assumed certain
liabilities of Wakefield Engineering, Inc., a wholly-owned subsidiary of EG&G,
Inc. The purchase price, which in aggregate amounted to approximately
$5,725,000, included a $4,637,000 cash payment, an estimated payable of
$759,000 to EG&G, Inc. and estimated expenses of $329,000. On June 1, 1994, the

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

Systems Division of Microdot Inc. The aggregate purchase price of approximately
$5,075,000 included a net cash payment of $4,836,000 and expenses of $239,000.
The Company's share of the purchase price was $3,988,000. The minority interest
not acquired by the Company is included in income before provision for income
taxes on the consolidated statement of operations and as a separate item on the
consolidated balance sheet and statement of cash flows. On August 31, 1994,
Wakefield Engineering, Inc. ("Wakefield"), a wholly-owned subsidiary of the
Company, acquired substantially all of the assets and business of Aham Tor,
Inc. ("ATI"). The purchase price of $2,911,000 was paid in cash. Effective June
30, 1995, Wakefield acquired substantially all of the assets and business of
Specialty Extrusion Ltd. ("Specialty"). The purchase price of $2,000,000 was
paid in cash. In addition, the Company paid existing Specialty debt in the
amount of $560,000. The acquisitions have been accounted for as purchase
transactions, and accordingly, the purchase price has been allocated to the
assets acquired and liabilities assumed for each acquisition. Goodwill, which
relates to the ATI and Specialty acquisitions, represents the excess of cost
over the fair value of the net assets acquired and is being amortized over 15
years using the straight-line method. Adjustments to the purchase price may be
made during the 12 months following the date of acquisition as a result of
resolutions of uncertainties existing at the acquisition date. The operating
results of Wakefield, Uni-Star, ATI and Specialty have been included in the
Company's consolidated results of operations since their respective acquisition
dates of October 22, 1993, June 1, 1994, August 31, 1994, and June 30, 1995.
 
  The following unaudited pro forma summary is not necessarily indicative
either of results of operations that would have occurred had the purchase been
made on November 1, 1992, or of future results of operations of the combined
companies. Total revenues included in the following unaudited pro forma summary
reflect the effect of accounting for ISS as a discontinued operation. Net
income included in the following unaudited pro forma summary does not reflect
the effect of income from discontinued operations or the gain on sale of
discontinued operations.

  The revolving credit facility, variable equipment term loan and variable
equipment credit facility relate to a Loan and Security Agreement (the "Loan
Agreement") entered into by Wakefield in June of 1994. The Loan Agreement was
amended in May of 1995 to increase the revolving credit facility from a maximum
aggregate commitment of $4,000,000 to $7,000,000 and to extend the term of such
facility to May 5, 1997. The equipment credit facility was increased from a
maximum aggregate amount of $600,000 to $1,050,000. The proceeds from the
equipment credit facility may be used only for the purchase of capital
equipment. In addition, Wakefield entered into an equipment term note in the
amount of $265,000. Interest accrues at the bank's corporate base rate plus
three-quarters of one percent. The obligations under the Loan Agreement are
secured by a first lien and assignment of the assets of Wakefield, exclusive of
the assets of Specialty Extrusion Corp., including without limitation, all
accounts receivable, inventory, equipment and general intangibles which in
aggregate totals $18,789,000. The terms of the Loan Agreement include various
covenants which provide for, among other things, the maintenance of a tangible
capital base at various levels throughout the commitment period. On July 30,
1995, Wakefield was in compliance with these covenants. On July 30, 1995,
$6,279,000 was outstanding on the revolving credit facility.
 
  Interest paid on all outstanding debt amounted to approximately $116,000 in
fiscal year 1994 and approximately $479,000 for the nine months ended July 30,
1995.

  Management intends to renew the revolving credit facility upon its maturity.
 
  On August 30, 1995, Uni-Star entered into an Accounts Receivable Loan
Agreement which included a revolving credit commitment in the aggregate
principal amount of $2,500,000. Uni-Star also entered into an equipment term
loan in the amount of $750,000 and an equipment acquisition facility of
$300,000. Interest on the revolving credit commitment accrues at the bank's
prime rate plus one half of one percent and interest on the equipment term loan
accrues at the bank's prime rate plus three quarters of one percent. The
equipment term loan is repayable in 48 equal monthly installments of principal
of $15,625 plus accrued interest, payable on the first day of each month
beginning October 1, 1995. All of the Uni-Star credit facilities are secured by
a first lien and assignment of substantially all of its assets, including
without limitation, accounts receivable, inventory, equipment and general
intangibles.

  The accrued lease differential primarily represents the lease payments and
estimated costs that the Company expects to incur related to office space in
Houston, Texas less estimated payments that it expects to receive for
subleasing this space. Approximately $800,000 of the accrued lease differential
was expensed in fiscal 1994 in connection with the sale of the discontinued
operation. The remainder of the accrued lease differential was expensed in
fiscal 1992 as restructuring costs related to the office space.
 
10. PREFERRED STOCK

14. INCOME TAXES
 
  On November 1, 1993, the Company adopted Statement 109 through a cumulative
catch-up adjustment. The implementation of this statement did not have a
material effect on the Company's balance sheet or results of operations. The
Company's profitable operations during fiscal 1994 and during the nine months
ended July 30, 1995 resulted in the utilization of net operating loss
carryforwards, the tax benefit of which was fully reserved upon implementation
of Statement 109. Income taxes for fiscal year 1993 were accounted for in
compliance with APB Opinion No. 11: therefore, the tax benefit of net operating
loss carryforwards was classified as an extraordinary credit which reduced
taxes for the year by $97,000.
 
  The provisions for income taxes were as follows (in thousands):

</TABLE>
 
  Due to the Company's historical results of operations, a valuation allowance
was provided for the deferred tax assets on November 1, 1993. Because the
Company generated taxable income and was able to utilize net operating loss
carryforwards during fiscal 1994 and the nine months ended July 30, 1995 and,
due to an increase in the likelihood of the future realization of the net
deferred tax asset, the Company reversed $1,360,000 and $1,256,000,
respectively, of the valuation allowance. On July 30, 1995, the Company had,
for tax purposes, net operating loss carryforwards of approximately $14,613,000
and unused investment and research and development tax credits of approximately
$814,000 available to offset future taxable income and Federal income taxes.
The net operating loss carryforwards will expire from 2000 to 2008, and the tax
credit carryforwards will expire from 1995 to 2005. All carryforwards are
subject to review and possible adjustment by the Internal Revenue Service. In
compliance with the Tax Reform Act of 1986, investment tax credits carried
forward were reduced by 35%. The Company's ability to utilize the net operating
loss carryforwards to offset alternative minimum taxable income is limited to
90% for tax years after fiscal 1987.
 
  Additionally, Section 382 of the Internal Revenue Code limits the amounts of
net operating loss carryforwards usable by a corporation following a more than
50 percentage point change in ownership of the corporation during a three-year
period. It is possible that subsequent transactions involving the Company's
capital stock could result in such a limitation. As of July 30, 1995,
Management believes that such a change in ownership has not occurred.

1994, respectively, and $943,000 in the nine months ended July 30, 1995.
Expected sublease payments for each twelve month period ending July 30 are as
follows: 1996 $610,000; 1997 $610,000; 1998 $305,000; and 1999 and thereafter
$0. See Note 9.
 
  Through September 30, 1994, the Company, for its Information Solutions
Segment, had a partially self-funded insurance program for its group health
insurance plan. Effective January 1, 1995, Wakefield implemented the same type
of program for its group health insurance plan. Under these plans, the Company
assumed liability for payment of medical claims below a specific dollar amount
related to any one individual. The Company is also insured if claims should
exceed a specific aggregate dollar amount for all covered individuals. Asserted
and unasserted medical/health insurance claims are accrued for based on the
Company's experience and the advice of an independent claims manager.
 
16. RELATED-PARTY TRANSACTIONS
 
  For services rendered in connection with the acquisitions made during fiscal
years 1993 and 1994, further described in Note 2--Acquisitions, the Company
paid $75,000 each and $57,500 each, respectively for fiscal 1993 and 1994, to
two corporations, which are general partners of a partnership having a greater
than 5% ownership of the Company. The sole stockholders of the aforementioned
corporations are currently employee directors of the Company. In fiscal 1993,
the two individuals were each granted a ten-year nonincentive stock option to
purchase 50,000 shares of the Company's common stock. In fiscal 1994, the two
individuals were each granted five-year nonincentive stock options to purchase
an aggregate of 120,000 shares of the Company's common stock. The options were
granted at an exercise price equal to the fair value of the common stock on the
dates of grant. The right to exercise these options vests in equal installments
over three years.
 
17. SUBSEQUENT EVENT
 
  The Company is in the process of purchasing the remaining 20% interest of
Uni-Star Industries, Inc. for 365,000 shares of restricted common stock with a
market value of approximately $2,700,000. This purchase will increase the basis
of Uni-Star's assets by $1,080,000 and will eliminate the book value of the
minority interest.

the Company, or because such director or officer serves or served as a
representative of another entity at the Company's request, so long as the
director or officer acted in good faith and in a manner he or she reasonable
believed to be in, or not opposed to, the best interests of the Company.

ITEM 17. Undertakings
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
  The undersigned registrant hereby undertakes that:
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  a registration statement in reliance upon Rule 430A and contained in the
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of the
  registration statement as of the time it was declared effective.
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

          (a)  The Company will use its best efforts to cause the Registration
     Statement, if not effective at the Execution Time, and any amendment
     thereof, to become effective.  Prior to the termination of the offering of
     the Securities, the Company will not file any amendment of the Registration
     Statement or supplement to the Prospectus or any Rule 462(b) Registration
     Statement without your prior consent.  Subject to the foregoing sentence,
     if the Registration Statement has become or becomes effective pursuant to
     Rule 430A, or filing of the Prospectus is otherwise required under Rule
     424(b), the Company will cause the Prospectus, properly completed, and any
     supplement thereto to be filed with the Commission pursuant to the
     applicable paragraph of Rule 424(b) within the time period prescribed and
     will provide evidence satisfactory to the Representative of such timely
     filing.  If the Rule 434 Delivery Alternative is used, the Company will
     also cause the Rule 434 Term Sheet, properly completed, to be filed with
     the Commission pursuant to Rule 434 within the time period prescribed and
     will provide evidence satisfactory to the Representative of such timely
     filing.  Upon your request, the Company will cause the Rule 462(b)
     Registration Statement, properly completed, to be filed with the Commission
     pursuant to Rule 462(b) and will provide evidence satisfactory to the
     Representative of such filing.  The Company will promptly advise the
     Representative (A) when the Registration Statement, if not effective at
     the Execution Time, and any amendment thereto, shall have become effective,
     (B) when the Prospectus, and any supplement thereto, any Rule 434 Term
     Sheet or any Rule 462(b) Registration Statement shall have been filed (if
     required) with the Commission pursuant to the applicable rule under the
     Act, (C) when, prior to termination of the offering of the Securities, any
     amendment to the Registration Statement shall have been filed or become
     effective, (D) of any request by the Commission for any amendment of the
     Registration Statement or supplement to the Prospectus or for any
     additional information, (E) of the issuance by the Commission of any stop
     order suspending the effectiveness of the Registration Statement or the
     institution or threatening of any proceeding for that purpose and (F) of
     the receipt by the Company of any notification with respect to the
     suspension of the qualification of the Securities for sale in any
     jurisdiction or the initiation or threatening of any
<PAGE>
 
                                                                              12

     proceeding for such purpose.  The Company will use its best efforts to
     prevent the issuance of any such stop order and, if issued, to obtain as
     soon as possible the withdrawal thereof.

          (b)  If, at any time when a prospectus relating to the Securities is
     required to be delivered under the Act, any event occurs as a result of
     which the Prospectus as then supplemented would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein in the light of the circumstances under
     which they were made not misleading, or if it shall be necessary to amend
     the Registration Statement or supplement the Prospectus to comply with the
     Act or the Exchange Act or the respective rules thereunder, the Company
     promptly will prepare and file with the Commission, subject to the second
     sentence of paragraph (a) of this Section 5, an amendment or supplement
     which will correct such statement or omission or effect such compliance.

          (c)  As soon as practicable, the Company will make generally available
     to its security holders and to the Representative an earnings statement or
     statements of the Company and its subsidiaries which will satisfy the
     provisions of Section 11(a) of the Act and Rule 158 under the Act.

          (d)  The Company will furnish to the Representative and counsel for
     the Underwriters, without charge, signed copies of the Registration
     Statement (including exhibits thereto) and to each other Underwriter a copy
     of the Registration Statement (without exhibits thereto) and, so long as
     delivery of a prospectus by an Underwriter or dealer may be required by the
     Act, as many copies of each Preliminary Prospectus and the Prospectus and
     any supplement thereto as the Representative may reasonably request.  The
     Company will pay the expenses of printing or other production of all
     documents relating to the offering.

          (e)  The Company will arrange for the qualification of the Securities
     for sale under the laws of such jurisdictions as the Representative may
     designate, will maintain such qualifications in effect so long as required
     for the distribution of the Securities and will pay the fee of the National

     Association of Securities Dealers, Inc., in connection with its review of
     the offering.

          (f)  The Company will not, for a period of 180 days following the
     Execution Time, without the prior written consent of Unterberg Harris,
     offer, sell or contract to sell, or otherwise dispose of, directly or
     indirectly, or announce the offering of, any other shares of Common Stock
     or any securities convertible into, or exchangeable for, shares of Common
     Stock; provided, however, that the Company may issue and sell Common Stock
            --------  -------                                                  
     pursuant to any employee stock option plan, stock ownership plan,
     restricted stock purchase plan or dividend reinvestment plan of the Company
     in effect at the Execution Time and the Company may issue Common Stock
     issuable upon the conversion of securities or the exercise of warrants
     outstanding at the Execution Time.

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

     form in all material respects with the applicable requirements of the Act,

     will conflict with, result in a breach or violation of, or constitute a
     default under any law or the charter or by-laws of the Company or the terms
     of any indenture or other agreement or instrument known to such counsel and
     to which the Company or any of its subsidiaries is a party or bound or any
     judgement, order or decree known to such counsel to be applicable to the
     Company or any of its subsidiaries of any court, regulatory body,
     administrative agency, governmental body or arbitrator having jurisdiction
     over the Company or any of its subsidiaries; and

          (d)  The Company shall have furnished to the Representative a
certificate of the Company, signed by the Chairman of the Board or the President

Prospectus and this Agreement and that:

          (i) the representations and warranties of the Company in this
     Agreement are true and correct in all material respects on and as of the

     Company has complied with all the agreements and satisfied all the
     conditions on its part to be performed or satisfied at or prior to the
     Closing Date;

          (ii) no stop order suspending the effectiveness of the Registration
     Statement has been issued and no proceedings for that purpose have been
     instituted or, to the Company's knowledge, threatened; and
<PAGE>
 
                                                                              18

         (iii) since the date of the most recent financial statements included
     in the Prospectus (exclusive of any supplement thereto), there has been no
     material adverse change in the condition (financial or other), earnings,
     business or properties of the Company and its subsidiaries, whether or not
     arising from transactions in the ordinary course of business, except as set
     forth in or contemplated in the Prospectus (exclusive of any supplement
     thereto).

          (e)  At the Execution Time and at the Closing Date, Arthur Andersen
LLP, shall have furnished to the Representatives a letter or letters, dated
respectively as of the Execution Time and as of the Closing Date, in form and
substance satisfactory to the Representative, confirming that they are
independent accountants within the meaning of the Act and the Exchange Act and
the respective applicable published rules and regulations thereunder and stating
in effect that:

          (i) in their opinion the audited financial statements and financial
     statement schedules included in the Registration Statement and the
     Prospectus and reported on by them comply as to form in all material
     respects with the applicable accounting requirements of the Act, the
     Exchange Act and the related published rules and regulations;

          (ii) on the basis of a reading of the latest unaudited financial
     statements made available by the Company and its Subsidiaries; carrying out
     certain specified procedures (but not an examination in accordance with
     generally accepted auditing standards) which would not necessarily reveal
     matters of significance with respect to the comments set forth in such
     letter; a reading of the minutes of the meetings of the stockholders,
     directors and stock option and compensation committees of the Company and
     the Subsidiaries; and inquiries of certain officials of the Company who
     have responsibility for financial and accounting matters of the Company and
     its subsidiaries as to transactions and events subsequent to July 30, 1995,
     nothing came to their attention which caused them to believe that with
     respect to the period subsequent to July 30, 1995, there were any changes,
     at a specified date not more than five business days prior to the date of
     the letter, in the long-term debt of the Company and its subsidiaries or
     capital stock of the
<PAGE>
 
                                                                              19

     Company or decreases in the stockholders' equity of the Company or
     decreases in working capital of the Company and its subsidiaries as
     compared with the amounts shown on the July 30, 1995 consolidated balance
     sheet included in the Registration Statement and the Prospectus, or for the
     period from July 30, 1995 to such specified date there were any decreases,
     as compared with the corresponding period in the preceding fiscal year, in
     subsidiaries' gross profit or income before taxes or in total or per share
     amounts of net income of the Company and its subsidiaries, except in all
     instances for changes or decreases set forth in such letter, in which case
     the letter shall be accompanied by an explanation by the Company as to the
     significance thereof unless said explanation is not deemed necessary by the
     Representative;

          (iii) they have performed certain other specified procedures as a
     result of which they determined that certain information of an accounting,
     financial or statistical nature (which is limited to accounting, financial
     or statistical information derived from the general accounting records of
     the Company and its subsidiaries) set forth in the Registration Statement
     and the Prospectus agrees with the accounting records of the Company and
     its subsidiaries, excluding any questions of legal interpretation; and

          (iv) On the basis of a reading of the unaudited pro forma financial
     statements included in the Registration Statement and the Prospectus (the
     "pro forma financial statements"), carrying out certain specified
     procedures, inquiries of certain officials of the Company who have
     responsibility for financial and accounting matters, and proving the
     arithmetic accuracy of the application of the pro forma adjustments to the
     historical amounts in the pro forma financial statements, nothing came to
     their attention which caused them to believe that the pro forma financial
     statements do not comply in form in all material respects with the
     applicable accounting requirements of Rule 11-02 of Regulation S-X or that
     the pro forma adjustments have not been properly applied to the historical
     amounts in the compilation of such statements.

          References to the Prospectus in this paragraph (e) include any
supplement thereto at the date of the letter.
<PAGE>
 
                                                                              20

          The Representative shall have also received from Arthur Andersen LLP a
letter stating that the Company's system of internal accounting controls taken
as a whole is sufficient to meet the broad objectives of internal accounting
control insofar as those objectives pertain to the prevention or detection of
errors or irregularities in amounts that would be material in relation to the
financial statements of the Company and its subsidiaries.

          (f)  Subsequent to the Execution Time or, if earlier, the dates as of
which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Prospectus (exclusive of any supplement thereto),
there shall not have been (i) any change or decrease specified in the letter or
letters referred to in paragraph (e) of this Section 6 or (ii) any change, or
any development involving a prospective change, in or affecting the business or
properties of the Company and its subsidiaries the effect of which, in any case
referred to in clause (i) or (ii) above, is, in the judgment of the
Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Registration Statement (exclusive of any amendment thereof)
and the Prospectus (exclusive of any supplement thereto).

          (g)  At the Execution Time, the Company shall have furnished to the
Representative a letter substantially in the form of Exhibit A hereto from each
executive officer and director of the Company and Steel Partners, L.P. and
Steel Partners II, L.P. addressed to the Representative, in which each such
person agrees not to offer, sell or contract to sell, or otherwise dispose of,
directly or indirectly, or announce an offering of, any shares of Common Stock
beneficially owned by such person or any securities convertible into, or
exchangeable for, shares of Common Stock for a period of 180 days following the
Execution Time without the prior written consent of Unterberg Harris other
than shares of Common Stock disposed of as bona fide gifts.

          (h)  Prior to the Closing Date, the Company shall have furnished to
the Representative such further information, certificates and documents as the
Representative may reasonably request.

          If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material
<PAGE>
 
                                                                              21

respects when and as provided in this Agreement, or if any of the opinions and
certificates mentioned above or elsewhere in this Agreement shall not be in all
material respects reasonably satisfactory in form and substance to the
Representative and counsel for the Underwriters, this Agreement and all
obligations of the Underwriters hereunder may be canceled at, or at any time
prior to, the Closing Date by the Representative.  Notice of such cancellation
shall be given to the Company in writing or by telephone or telegraph confirmed
in writing.

          7.  Reimbursement of Underwriters' Expenses.  If the sale of the
              ----------------------------------------                    
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
because of any termination pursuant to Section 10 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally upon demand for all out-of-pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been incurred by them in
connection with the proposed purchase and sale of the Securities.

          8.  Indemnification and Contribution.  (a)  The Company agrees to
              ---------------------------------                            
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the  Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to which they or any
of them may become subject under the Act, the Exchange Act or other Federal or
state statutory law or regulation, at common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement for the registration of
the Securities as originally filed or in any amendment thereof, or in any
Preliminary Prospectus or the Prospectus, or in any amendment thereof or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or
<PAGE>
 
                                                                              22

defending any such loss, claim, damage, liability or action; provided, however,
                                                             --------  ------- 
that (i) the Company will not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to the Company by or on behalf of any Underwriter through the
Representative specifically for inclusion therein and (ii) such indemnity with
respect to any Preliminary Prospectus shall not inure to the benefit of any
Underwriter (or any director, officer, employee or agent of such Underwriter or
any person controlling such Underwriter) from whom the person asserting any such
loss, claim, damage or liability purchased the Securities that are the subject
thereof if such person did not receive a copy of the Prospectus (or the
Prospectus as supplemented) excluding documents incorporated therein by
reference at or prior to the confirmation of the sale of such Securities to such
person in any case where such delivery is required under the Act and any untrue
statement or omission of a material fact contained in any Preliminary Prospectus
was corrected in the Prospectus (or the Prospectus as supplemented).  This
indemnity agreement will be in addition to any liability which the Company may
otherwise have.

          (b)  Each Underwriter severally agrees to indemnify and hold harmless
the Company, each of its directors, each of its officers who signs the
Registration Statement, and each person who controls the Company within the
meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity to each Underwriter, but only with reference to written
information relating to such Underwriter furnished to the Company by or on
behalf of such Underwriter through the Representatives specifically for
inclusion in the documents referred to in the foregoing indemnity.  This
indemnity agreement will be in addition to any liability which any Underwriter
may otherwise have.  The Company acknowledges that the statements set forth in
each Preliminary Prospectus and the Prospectus constitute the only information
furnished in writing by or on behalf of the several Underwriters for inclusion
in any Preliminary Prospectus or the Prospectus, and you, as the
Representative, confirm that such statements are correct.

          (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in
<PAGE>
 
                                                                              23

respect thereof is to be made against the indemnifying party under this Section
8, notify the indemnifying party in writing of the commencement thereof; but the
failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above.  The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
                            --------  -------                            
satisfactory to the indemnified party.  Notwithstanding the indemnifying party's
election to appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including
local counsel), and the indemnifying party shall bear the reasonable fees, costs
and expenses of such separate counsel if (i) the use of counsel chosen by the
indemnifying party to represent the indemnified party would present such counsel
with a conflict of interest, (ii) the actual or potential defendants in, or
targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party.  An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an
<PAGE>
 
                                                                              24

unconditional release of each indemnified party from all liability arising out
of such claim, action, suit or proceeding.

          (d)  In the event that the indemnity provided in paragraph (a) or (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and by the
Underwriters on the other from the offering of the Securities; provided,
                                                               -------- 
however, that in no case shall any Underwriter (except as may be provided in any
- -------                                                                         
agreement among underwriters relating to the offering of the Securities) be
responsible for any amount in excess of the underwriting discount or commission
applicable to the Securities purchased by such Underwriter hereunder.  If the
allocation provided by the immediately preceding sentence is unavailable for any
reason, the Company and the Underwriters shall contribute in such proportion as
is appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and of the Underwriters on the other in
connection with the statements or omissions which resulted in such Losses as
well as any other relevant equitable considerations.  Benefits received by the
Company shall be deemed to be equal to the total net proceeds from the offering
(before deducting expenses), and benefits received by the Underwriters shall be
deemed to be equal to the total underwriting discounts and commissions, in each
case as set forth on the cover page of the Prospectus.  Relative fault shall be
determined by reference to whether any alleged untrue statement or omission
relates to information provided by the Company or the Underwriters.  The Company
and the Underwriters agree that it would not be just and equitable if
contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above.  Notwithstanding the provisions of this paragraph (d), no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  For purposes of this Section 8, each person
who controls an Underwriter within the meaning of either the Act or the
<PAGE>
 
                                                                              25

Exchange Act and each director, officer, employee and agent of an Underwriter
shall have the same rights to contribution as such Underwriter, and each person
who controls the Company within the meaning of either the Act or the Exchange
Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to the applicable terms and
conditions of this paragraph (d).

          9.  Default by an Underwriter.  If any one or more Underwriters shall
              --------------------------                                       
fail to purchase and pay for any of the Securities agreed to be purchased by
such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; provided, however, that in the event that the aggregate amount of
          --------  -------                                                
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Securities set forth in
Schedule I hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Securities,
and if such nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter or
the Company.  In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
seven days, as the Representative shall determine in order that the required
changes in the Registration Statement and the Prospectus or in any other
documents or arrangements may be effected.  Nothing contained in this Agreement
shall relieve any defaulting Underwriter of its liability, if any, to the
Company and any nondefaulting Underwriter for damages occasioned by its default
hereunder.

          10.  Termination.  This Agreement shall be subject to termination in
               ------------                                                   
the absolute discretion of the Representative, by notice given to the Company
prior to delivery of and payment for the Securities, if prior to such time (i)
trading in the Company's Common Stock shall have
<PAGE>
 
                                                                              26

been suspended by the Commission or Nasdaq or trading in securities generally on
the New York Stock Exchange or Nasdaq shall have been suspended or limited or
minimum prices shall have been established on either of such Exchange or Market,
(ii) a banking moratorium shall have been declared either by Federal or New York
State authorities or (iii) there shall have occurred any outbreak or escalation
of hostilities, declaration by the United States of a national emergency or war
or other calamity or crisis the effect of which on financial markets is such as
to make it, in the judgment of the Representative, impracticable or inadvisable
to proceed with the offering or delivery of the Securities as contemplated by
the Prospectus (exclusive of any supplement thereto).

          11.  Representations and Indemnities to Survive. The respective
               -------------------------------------------               
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors or controlling persons referred to in Section 8 hereof,
and will survive delivery of and payment for the Securities.  The provisions of
Sections 7 and 8 hereof shall survive the termination or cancellation of this
Agreement.

          12.  Notices.  All communications hereunder will be in writing and
               --------                                                     
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telegraphed and confirmed to them, care of Unterberg Harris, Swiss
Bank Tower, 10 East 50th Street, 22nd Floor, New York, New York 10022; or, if
sent to the Company, will be mailed, delivered or telegraphed and confirmed to
it at 333 Cypress Run, Suite 360, Houston, Texas, Attention: Secretary.

          13.  Successors.  This Agreement will inure to the benefit of and be
               -----------                                                    
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 8 hereof, and no
other person will have any right or obligation hereunder.

          14.  Applicable Law.  This Agreement will be governed by and construed
               ---------------                                                  
in accordance with the laws of the State of New York.

agreement, please sign and return to us

          SECTION 1.05.  Notices, etc., to Trustee and Company.  Any request,
                         --------------------------------------

other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

          (a) the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder if made, given, furnished or filed in writing
     and mailed, first-class, postage prepaid, to the Trustee at its Corporate
     Trust Office, Attention of            , or

          (b) the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     in writing and mailed, first-class postage prepaid, to the Company
     addressed to it at the address of its principal office specified in the
     first paragraph of this instrument or at any other address previously
     furnished in writing to the Trustee by the Company, or

          (c) the Company by the Trustee or the Trustee by the Company shall be
     sufficient for every purpose hereunder (unless otherwise herein expressly
     provided) if transmitted by facsimile transmission to the Company at 
     (   )        or to the Trustee at (   )        (or to such other 
     facsimile transmission number previously furnished in writing to the

     confirmed by a copy sent to the Company or to the Trustee, as the case may

provides for notice to Holders of any event,

provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Debenture Register,
not later than the latest date and not earlier than the earliest date,
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice nor any defect in any
notice so mailed to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders.  Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice.  Waivers of notice by Holders shall be filed with
the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

imposed by, or with another provision (an "incorporated provision") included in
this Indenture by operation of, any of Sections 3.10 to 3.18, inclusive, of the
Trust Indenture Act, such imposed duties or incorporated provision shall
control.

                         -----------------------------                          
a duly authorized issue of Debentures of the Company designated as its   %
Convertible Subordinated Debentures Due 2005 (herein called the "Debentures"),
limited in aggregate principal amount to $25,000,000 (subject to increase as
provided in the Indenture of up to $28,750,000 aggregate principal amount),
issued and to be issued under an Indenture dated as of            , 1995 (herein
called the "Indenture"), between the Company and                              ,
as Trustee (herein called the "Trustee", which term includes any successor
trustee under the Indenture), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee, the holders of Senior Indebtedness and the Holders of the Debentures
and of the terms upon which the Debentures are, and are to be, authenticated and
delivered.

          Subject to and upon compliance with the provisions of the Indenture,
the Holder of this Debenture is entitled, at such Holder's option, at any time
on or before the close of business on          , 2005, or, in case this
Debenture or a portion hereof is called for redemption, then in respect of this
Debenture or such portion hereof until and including, but (unless the Company
defaults in making the payment due upon redemption) not after, the close of
business on the Business Day prior to the Redemption Date,
<PAGE>
 
                                                                              17

to convert this Debenture (or any portion of the principal amount hereof which
is $1,000 or any integral multiple thereof), at the principal amount hereof, or
of such portion, into fully paid and nonassessable shares (calculated as to each
conversion to the nearest 1/100 of a share) of Common Stock of the Company at a
conversion price equal to $     aggregate principal amount of Debentures for
each share of Common Stock (or at the current adjusted conversion price if an
adjustment has been made as provided in the Indenture) by surrender of this
Debenture, duly endorsed or assigned to the Company or in blank, at the office
or agency of the Company maintained for that purpose in the City of New York or
at any other office or agency maintained by the Company for such purpose,
accompanied by written notice to the Company that the Holder hereof elects to
convert this Debenture or, if less than the entire principal amount hereof is to
be converted the portion hereof to be converted, and, in case such surrender
shall be made during the period from the close of business on any Regular Record
Date next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date (unless this Debenture or the portion hereof being
converted has been called for redemption on a Redemption Date within such
period), also accompanied by payment in New York Clearing House or other funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of this Debenture then being
converted.  Subject to the aforesaid requirement for payment and, in the case of
a conversion after the Regular Record Date next preceding any Interest Payment
Date and on or before such Interest Payment Date, to the right of the Holder of
this Debenture (or any Predecessor Debenture) of record at such Regular Record
Date to receive an installment of interest (with certain exceptions provided in
the Indenture), no payment or adjustment is to be made on conversion for
interest accrued hereon or for dividends on the Common Stock issued on
conversion.  No fractions of shares or scrip representing fractions of shares
will be issued on conversion, but instead of any fractional interest the Company
shall pay a cash adjustment as provided in the indenture.  The conversion price
is subject to adjustment as provided in the Indenture.  In addition, the
Indenture provides that, in case of certain consolidations or mergers to which
the Company is a party or the conveyance or transfer of the properties and
assets of the Company substantially as an entirety, the Indenture shall be
amended, without the consent of any Holders of Debentures, so that this
Debenture, if then outstanding, will be

convertible thereafter, during the period this Debenture shall be convertible as
specified above, only into the kind and amount of securities, cash and other
property receivable upon the consolidation, merger, conveyance or transfer by a
holder of the number of shares of Common Stock of the Company into which this
Debenture might have been converted immediately prior to such consolidation,
merger, conveyance or transfer, assuming such holder of Common Stock of the
Company failed to exercise his rights of election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
consolidation, merger, conveyance or transfer (provided that, if the kind or
amount of securities, cash and other property so receivable is not the same for
each nonelecting share of Common Stock of the Company, then the kind and amount
of securities, cash and other property so receivable by each nonelecting share
shall be deemed to be the kind and amount so receivable per share by a plurality
of the nonelecting shares).

          The Debentures are subject to redemption upon not less than 30 nor
more than 60 days' notice by mail at any time, as a whole or in part, at the

and thereafter at a Redemption Price equal to 100% of the principal amount,

hereof, together with accrued interest to the Repurchase Date, but interest
installments whose Stated Maturity is on or prior to such Repurchase Date will
be payable to the Holders of such Debentures, or one or more Predecessor
Debentures, of record at the close of business on the relevant Record Dates
referred to on the face hereof, all as provided in the Indenture.  In connection
with the exercise of the repurchase right by a Holder prior to a Redemption
Date, a Holder's right to exercise such repurchase right shall terminate at the
close of business on the Business Day prior to the Redemption Date.

          In the event of redemption, repurchase or conversion of this Debenture
in part only, a new Debenture or Debentures for the unredeemed, unrepurchased or
unconverted portion hereof will be issued in the name of the Holder hereof upon
the cancelation hereof.

the manner set forth in the Indenture, expressly subordinated and subject in
right of payment to the prior payment in full of all Senior Indebtedness, as
defined in the Indenture, and this Debenture is issued subject to such
provisions of the Indenture, and each Holder of this Debenture, by accepting the
same, agrees to and shall be bound by such provisions and authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to acknowledge or effectuate the subordination as provided in the Indenture and
appoints the Trustee his attorney-in-fact for any and all such purposes.

          If an Event of Default shall occur and be continuing, the principal of
all the Debentures may be declared due and payable in the manner and with the
effect provided in the Indenture.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of not
less than two-thirds in aggregate principal amount of the Debentures at the time
Outstanding.  The Indenture also contains provisions permitting the Holders of a
majority in aggregate principal amount of the Debentures at the time
Outstanding, on behalf of the Holders of all the Debentures, to waive compliance
by the Company with certain provisions of the Indenture and certain past
defaults under

the Indenture and their consequences.  Any such consent or waiver by the Holder
of this Debenture shall be conclusive and binding upon such Holder and upon all
future Holders of this Debenture and of any Debenture issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Debenture.

          Except with respect to the rights of the holders of Senior
Indebtedness set forth in the Indenture and in this Debenture, no reference
herein to the Indenture and no provision of this Debenture or of the Indenture

who were at any time the proper officers of the Company shall bind the Company,

notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Debentures or did not
hold such offices at the date of such Debentures.

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Debentures executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Debentures; and the Trustee in accordance
with such Company order shall authenticate and deliver such Debentures as in
this Indenture provided and not otherwise.

          Each Debenture shall be dated the date of its authentication.

          No Debenture shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Debenture a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Debenture shall be conclusive evidence, and the only evidence, that such
Debenture has been duly authenticated and delivered hereunder.

          SECTION 3.04.  Temporary Debentures.  Pending the preparation of
                         ---------------------                            
definitive Debentures, the Company may execute, and upon Company Order the
Trustee shall authenticate and deliver, temporary Debentures which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Debentures in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Debentures may
determine, as evidenced by their execution of such Debentures.

          If temporary Debentures are issued, the Company will cause definitive
Debentures to be prepared without unreasonable delay.  After the preparation of
definitive Debentures, the temporary Debentures shall be exchangeable for
definitive Debentures upon surrender of the temporary Debentures, at any office
or agency of the Company designated pursuant to Section 10.02, without charge to
the Holder.  Upon surrender for cancelation of any one or more temporary
Debentures, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor
<PAGE>
 
                                                                              24

a like principal amount of definitive Debentures of authorized denominations.
Until so exchanged, the temporary Debentures shall in all respects be entitled
to the same benefits under this Indenture as definitive Debentures.

          SECTION 3.05.  Registration, Registration of Transfer and Exchange.
                         ---------------------------------------------------- 
The Company shall cause to be kept at the Corporate Trust Office of the Trustee
a register (the register maintained in such office being herein sometimes
referred to as the "Debenture Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Debentures and of transfers of Debentures.  The Trustee is hereby appointed
"Debenture Registrar" for the purpose of registering Debentures and transfers of
Debentures as herein provided.

          Upon surrender for registration of transfer of any Debenture at an
office or agency of the Company, the Company shall execute, and the Trustee
shall register on the Debenture Register and shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Debentures
of any authorized denominations, of a like aggregate principal amount.

          At the option of the Holder, Debentures may be exchanged for other
Debentures of any authorized denominations, of a like aggregate principal
amount, upon surrender of the Debentures to be exchanged at such office or
agency.  Whenever any Debentures are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Debentures
which the Holder making the exchange is entitled to receive.

          All Debentures issued upon any registration of transfer or exchange of
Debentures shall be the valid obligations of the Company, evidencing the same
debt and entitled to the same benefits under this Indenture, as the Debentures
surrendered upon such registration of transfer or exchange.

          Every Debenture presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company, the Trustee and the Debenture Registrar duly
executed, by the Holder thereof or his attorney duly authorized in writing.

                                                                              25

          No service charge shall be made for any registration of transfer or
exchange of Debentures, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Debentures, other than
exchanges pursuant to Section 3.04, 9.06, 11.08, 12.02 or 14.02(c) not involving
any transfer.

          Neither the Company nor the Trustee or Debenture Registrar shall be
required (a) to issue, authenticate or register the transfer of or exchange any
Debenture during a period beginning at the opening of business 15 days before
the day of the mailing of a notice of redemption of Debentures selected for
redemption under Section 11.04 and ending at the close of business on the day of
such mailing or (b) to register the transfer of or exchange any Debenture so
selected for redemption in whole or in part, except the unredeemed portion of
any Debenture being redeemed in part.

          SECTION 3.06.  Mutilated, Destroyed, Lost and Stolen Debentures.  If
                         -------------------------------------------------    
any mutilated Debenture is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Debenture of like tenor and principal amount and bearing a number not
contemporaneously outstanding.

          If there shall be delivered to the Company and the Trustee (a)
evidence to their satisfaction of the destruction, loss or theft of any
Debenture and (b) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Debenture has been acquired by a
bona fide purchaser, the Company shall execute and upon its request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Debenture, a new Debenture of like tenor and principal amount and bearing a
number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Debenture has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Debenture, pay such Debenture.

          Upon the issuance of any new Debenture under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
<PAGE>
 
                                                                              26

expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Debenture issued pursuant to this Section in lieu of any
destroyed, lost or stolen Debenture shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Debenture shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Debentures duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Debentures.

          SECTION 3.07.  Payment of Interest; Interest Rights Preserved.
                         ----------------------------------------------- 
Interest on any Debenture which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Debenture (or one or more Predecessor Debentures) is registered at the
close of business on the Regular Record Date for such interest.  The Company
shall deposit with the Trustee an amount of money equal to the aggregate amount
proposed to be paid in respect of such interest in immediately available funds
or shall make arrangements satisfactory to the Trustee for such deposit prior to
the date of the proposed payment, such money when deposited to be held in trust
for the benefit of the Persons entitled to such interest as in this clause
provided.

          Any interest on any Debenture which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (a) or (b) below:

          (a)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Debentures (or their respective
     Predecessor Debentures) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted Interest, which shall
     be fixed in the following manner.  The Company shall notify the Trustee in
     writing of the
<PAGE>
 
                                                                              27

     amount of Defaulted Interest proposed to be paid on each Debenture and the
     date of the proposed payment, and at the same time the Company shall
     deposit with the Trustee an amount of money equal to the aggregate amount
     proposed to be paid in respect of such Defaulted Interest or shall make
     arrangements satisfactory to the Trustee for such deposit prior to the date
     of the proposed payment, such money when deposited to be held in trust for
     the benefit of the Persons entitled to such Defaulted Interest as in this
     clause provided.  Thereupon the Trustee shall fix a Special Record Date for
     the payment of such Defaulted Interest which shall be not more than 15 days
     and not less than 10 days prior to the date of the proposed payment and not
     less than 10 days after the receipt by the Trustee of the notice of the
     proposed payment.  The Trustee shall promptly notify the Company of such
     Special Record Date and, in the name and at the expense of the Company,
     shall cause notice of the proposed payment of such Defaulted Interest and
     the Special Record Date therefor to be mailed, first-class postage prepaid,
     to each Holder at his address as it appears in the Debenture Register, not
     less than 10 days prior to such Special Record Date.  Notice of the
     proposed payment of such Defaulted Interest and the Special Record Date
     therefor having been so mailed, such Defaulted Interest shall be paid to
     the Persons in whose names the Debentures (or their respective Predecessor
     Debentures) are registered at the close of business on such Special Record
     Date and shall no longer be payable pursuant to the following clause (b).

          (b)  The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Debentures may be listed, and upon such
     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this clause,
     such manner of payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Debenture
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Debenture shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Debenture.

          In the case of any Debenture which is converted after any Regular
Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Debenture whose Maturity is prior to such Interest Payment Date),
interest whose Stated Maturity is on such Interest Payment Date shall be payable
on such Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name the Debenture (or one or more Predecessor Debentures) is
registered at the close of business on such Regular Record Date.  Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Debenture which is converted, interest whose Stated Maturity is after the
date of conversion of such Debenture shall not be payable.

          SECTION 3.08.  Persons Deemed Owners.  Prior to due presentment of a
                         ----------------------                               
Debenture for registration of transfer, the Company, the Trustee and any agent
of the Company or the Trustee may treat the Person in whose name such Debenture
is registered as the owner of such Debenture for the purpose of receiving
payment of principal of (and premium, if any) and (subject to Section 3.07)
interest on such Debenture and for all other purposes whatsoever, whether or not
such Debenture be overdue, and neither the Company, the Trustee nor any agent of
the Company or the Trustee shall be affected by notice to the contrary.

          SECTION 3.09.  Cancelation.  All Debentures surrendered for payment,
                         ------------                                         
redemption, registration of transfer or exchange or conversion shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it.  The Company may at any time deliver to
the Trustee for cancelation any Debentures previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Debentures so delivered shall be promptly canceled by the
Trustee.  No Debentures shall be authenticated in lieu of or in exchange for any
Debentures canceled as provided in this Section, except as expressly permitted
by this Indenture.  All canceled Debentures held by the Trustee shall be
destroyed and a certificate of destruction shall be delivered to the Company by
the Trustee.

          SECTION 3.10.  Computation of Interest.  Interest on the Debentures
                         ------------------------                            
shall be computed on the basis of a 360day year of twelve 30-day months.

          SECTION 3.11.  CUSIP Number.  The Company in issuing Debentures may

use a "CUSIP" number, and if so, the Trustee may use the CUSIP number in notices
of redemption or exchange as a convenience to Holders; provided that any such
                                                       --------              
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed in the notice or on the Debentures, and
that reliance may be placed only on the other identification numbers printed on
the Debentures.

                         ----------------------------------------      
Indenture shall cease to be of further effect (except as to any surviving rights
of conversion, registration of transfer or exchange of Debentures herein
expressly provided for), and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

          (a) either

               (i) all Debentures theretofore authenticated and delivered (other

          Debentures for whose payment money has theretofore been deposited in
          trust or segregated and held in trust by the Company and thereafter
          repaid to the Company or discharged from such trust, as provided in
          Section 10.03) have been delivered to the Trustee for cancelation; or

          or caused to be deposited with the Trustee as trust funds in trust for
          that purpose funds sufficient to pay and discharge the entire
          indebtedness on such Debentures not theretofore delivered to the
          Trustee for cancelation, for principal (and premium, if any) and
          interest to the date of such deposit (in the case of Debentures which
          have become due and payable) or to the Stated Maturity or Redemption
          Date, as the case may be and, in the case of (B) or (C) above, has
          delivered to the Trustee an Opinion of Counsel stating that (1) the
          Company has received from, or there has been published by, the
          Internal Revenue Service a ruling or (2) since the date of the
          Indenture, there has been a change in the applicable United States
          Federal income tax law, in either case to the effect that, and based
          thereon such Opinion of Counsel shall confirm that, the Holders of the
          Debentures will not recognize income, gain or loss for United States
          Federal income tax purposes as a result of such satisfaction and
          discharge and will be subject to United States Federal income tax on
          the same amounts, in the same manner and at the same times as would
          have been the case if such satisfaction and discharge had not
          occurred;

          (b) the Company has paid or caused to be paid all other sums payable
     hereunder by the Company; and

          (c) the Company has delivered to the Trustee an Officers' Certificate
     and an opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.07 and the obligations
of the Trustee to any Authenticating Agent under Section 6.13 shall survive.

directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of

          SECTION 5.02.  Acceleration of Maturity; Rescission and Annulment.  If
                         ---------------------------------------------------    
an Event of Default occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures may declare the principal of all the Debentures to be due
and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal shall
become immediately due and payable.

          At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of a majority
in principal amount of the Outstanding Debentures, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequence if:

          (a) the Company has paid or deposited with the Trustee a sum
     sufficient to pay

                (i) all overdue installments of interest on all Debentures;

               (ii) the principal of (and premium, if any, on) any Debentures
          which have become due otherwise than by such declaration of
          acceleration and interest thereon at the rate borne by the Debentures;

              (iii) to the extent that payment of such interest is lawful,
          interest upon overdue installments of interest at the rate borne by
          the Debentures; and

               (iv) all sums paid or advanced by the Trustee hereunder and the

          (b) all Events of Default, other than the nonpayment of the principal
     of Debentures which have become due solely by such declaration of
     acceleration, have been cured or waived as provided in Section 5.13.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

          SECTION 5.03.  Collection of Indebtedness and Suits for Enforcement by
                         -------------------------------------------------------
Trustee.  The Company covenants that if:
- --------                                

          (a) default is made in the payment of any installment of interest on
     any Debenture when such interest becomes due and payable and such default
     continues for a period of 30 days;

          (b) default is made in the payment of the principal of (or premium, if
     any, on) any Debenture at the Maturity thereof; or

     Repurchase Date therefor in accordance with the provisions of Article XIV;

the Company will upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Debentures, the whole amount then due and payable on such
Debentures for principal (and premium, if any) and interest, with interest upon
the overdue principal (and premium, if any) and, to the extent that payment of
such interest shall be legally enforceable, upon overdue installments of
interest, at the rate borne by the Debentures; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of sums so due and unpaid, may prosecute
such proceeding to judgment or final decree and may enforce the same against the
Company or any other obligor upon the Debentures and collect the moneys adjudged
or decreed to be payable in the manner provided by law out of the property of
the Company or any other obligor upon the Debentures, wherever situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

          SECTION 5.04.  Trustee May File Proofs of Claim.  In case of the

reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Debentures or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Debentures shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue

proceeding or otherwise,

          (a) to file and prove a claim for the whole amount of principal (and
     premium, if any) and interest owing and unpaid in respect of the Debentures
     and to file such other papers or documents as may be necessary or advisable
     in order to have the claims of the Trustee (including any claim for the
     reasonable compensation, expenses, disbursements and advances of the
     Trustee, its agents and counsel) and of the Holders allowed in such
     judicial proceeding; and

          (b) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same after deduction
     of its charges and expenses;

and any receiver, assignee, trustee, liquidator, sequestrator or other similar
official in any such judicial proceeding is hereby authorized by each Holder to
make such payments to the Trustee and, in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan or
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

          SECTION 5.05.  Trustee May Enforce Claims Without Possession of

of any of the Debentures or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in

applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Debentures and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

     a continuing Event of Default;

          (b) the Holders of not less than 25% in principal amount of the

     indemnity against the costs,

     expenses and liabilities to be incurred in compliance with such request;

          (d) the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

          (e) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     principal amount of the outstanding Debentures;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

          SECTION 5.08. Right of Holders To Receive Principal, Premium and

Section 3.07) interest on such Debenture on the Stated Maturity expressed in
such Debenture (or, in the case of redemption or repurchase, on the Redemption
Date or Repurchase Date) and to convert such Debenture in accordance with
Article XII and to institute suit for the enforcement of any such payment and
right to convert, and such rights shall not be impaired without the consent of
such Holder.

          SECTION 5.09.  Restoration of Rights and Remedies.  If the Trustee or

to be exclusive of any other right or remedy, and every right and remedy shall,
to the extent permitted by law, be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise.  The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

          SECTION 5.11.  Delay or Omission Not Waiver.  No delay or omission of
                         -----------------------------                         
the Trustee or of any Holder of any Debenture to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the

principal amount of the Outstanding Debentures shall have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Trustee or exercising any trust or power conferred on the Trustee;
provided that:
- --------      

          (a) such direction shall not be in conflict with any rule of law or
     with this Indenture;

          (b) such direction is not unduly prejudicial to the other security
     holders or may involve the Trustee in personal liability or if the Trustee
     determines that it does not have sufficient indemnity against any loss or
     expense connected to such action; and

          (c) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction.

          SECTION 5.13.  Waiver of Past Defaults.  The Holders of not less than
                         ------------------------

the Holders of all the Debentures waive any past default hereunder and its
consequences, except a default:

     interest on any Debenture; or

          (b) in respect of a covenant or provision hereof which under Article
     IX cannot be modified or amended without the consent of the Holder of each
     Outstanding Debenture affected.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

          SECTION 5.14.  Undertaking for Costs.  All parties to this Indenture
                         ----------------------                               
agree, and each Holder of any Debenture by such Holder's acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require, in
any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Debentures or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium, if any) or interest
on any Debenture on or after the Stated Maturity expressed in such Debenture
(or, in the case of redemption or repurchase, on or after the Redemption Date or
Repurchase Date) or for the enforcement of the right to convert any Debenture in
accordance with Article XII.

                         ----------------------------------------             
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay, usury or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so)

hereby expressly waives all benefit or advantage of any such law and covenants
that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

                                  The Trustee

during the continuance of an Event of Default:

          (i) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture, and no implied covenants
     or obligations shall be read into this Indenture against the Trustee; and

         (ii) in the absence of wilful misconduct on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture, but, in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture.

          (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

          (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own wilful misconduct, except that:
                                     ------      

          (i) this subsection shall not be construed to limit the effect of

          (ii) the Trustee shall not be liable for any error of judgment made by
     a Responsible Officer, unless it shall be proved that the Trustee was
     negligent in ascertaining the pertinent facts;

         (iii) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in accordance with the direction of the
     Holders of a majority in principal amount of the Outstanding Debentures
     relating to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee, or exercising any trust or power conferred
     upon the Trustee, under this Indenture; and

          (iv) no provision of this Indenture shall require the Trustee to
     expend or risk its own funds or otherwise incur any financial liability in
     the performance of any of its duties hereunder, or in the exercise of any
     of its rights or powers, if it shall have reasonable grounds for believing
     that repayment of such funds or adequate indemnity against such risk or
     liability is not reasonably assured to it.

          (d)  Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

                         -------------------                          
occurrence of any default hereunder, the Trustee shall transmit by mail to all
Holders, as their names and addresses appear in the Debenture Register, notice
of such default hereunder known to the Trustee, unless such default shall have
been cured or waived; provided, however, that, except in the case of a default
                      --------  -------                                       
in the payment of the principal of (or premium, if any) or interest on any
Debenture, the Trustee shall be protected in withholding such notice if and so
long as a trust committee of Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interest of the
Holders; provided further that, in the case of any default of the character
         ----------------                                                  
specified in Section 5.01(d), no such notice to Holders shall be given until at
least 30 days after the occurrence thereof.  For the purpose of this Section,
the term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default.  The Trustee shall not be deemed to have
knowledge of any default other than those described in

          SECTION 6.04.  Not Responsible for Recitals or Issuance of Debentures.
                         ------------------------------------------------------ 
The recitals contained herein and in the Debentures, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness.  The Trustee
makes no representations as to the validity or sufficiency of this Indenture or
of the Debentures.  The Trustee shall not be accountable for the use or
application by the Company or any Paying Agent other than the Trustee of
Debentures or the proceeds thereof.

          SECTION 6.05.  May Hold Debentures.  The Trustee, any Authenticating
                         --------------------                                 
Agent, any Paying Agent, any Debenture Registrar or any other agent of the
Company, in its individual or any other capacity, may become the owner or
pledgee of Debentures and, subject to Section 6.12 and to Section 310(b) of the
Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Debenture
Registrar or such other agent.

          Subject to Section 310(b) of the Trust Indenture Act, the Trustee may
become and act as trustee under other indentures under which other securities,
or certificates of interest or participation in other securities, of the Company
are outstanding in the same manner as if it were not Trustee.

          SECTION 6.06.  Money Held in Trust.  Money held by the Trustee in

money received by it hereunder except as otherwise agreed on with the Company.

          SECTION 6.07.  Compensation and Reimbursement.  The Company agrees:
                         -------------------------------                     

          (a) to pay to the Trustee from time to time such compensation as may
     be agreed upon by the Trustee and the Company from time to time for all
     services rendered by it hereunder (which compensation shall not be limited
     by any provision of law in regard to the compensation of a trustee of an
     express trust);

          (b) to reimburse the Trustee upon its request for all reasonable
     expenses, disbursements and advances incurred or made by the Trustee in
     accordance with any provision of this Indenture (including the reasonable
     compensation and the expenses and disbursements of its agents, counsel and
     other persons not regularly in its employ), except to the extent any such
     expense,, disbursement or advance may be attributable to its negligence or
     bad faith; and

          (c) to indemnify the Trustee (in its individual capacity and as
     Trustee), its officers, directors, attorneys-in-fact and agents for, and to
     hold each such person harmless against, any loss, claim, damage, liability
     or expense, incurred without negligence or bad faith on such person's part,
     arising out of or in connection with the acceptance or administration of
     this trust, including the costs and expenses of defending itself against or
     investigating any claim or liability in connection with the exercise or
     performance of any of its powers or duties hereunder.  The obligations of
     the Company under this Section 6.07 to compensate and indemnify the Trustee
     and to pay or reimburse the Trustee for expenses, disbursements and
     advances shall constitute additional indebtedness hereunder and shall
     survive the satisfaction and discharge of this Indenture.  To secure the
     Company's payment obligations in this Section 6.07, the Trustee shall have
     a lien prior to the Debentures on all money or property held or collected
     by the Trustee except money or property held in trust to pay principal of
     (and premium, if any) or interest on particular Debentures and such lien
     shall survive the satisfaction and discharge of the Indenture and any other
     termination of the Indenture including any termination

     under any bankruptcy law.  When the Trustee incurs expenses or renders
     services in connection with an Event of Default of Section 5.01(6) or
     501(7), the Holders by their acceptance of the Debentures hereby agree that
     such expenses and the compensation for such services are intended to
     constitute expenses of administration under any bankruptcy law.  "Trustee"
     for the purposes of this Section 6.07 shall include any predecessor
     Trustee, but the negligence or willful misconduct of any Trustee shall not
     affect the indemnification of any other Trustee.

          SECTION 6.08.  Corporate Trustee Required; Eligibility.  The Trustee
                         ----------------------------------------             
shall at all times satisfy the eligibility requirements of Section 310 of the
Trust Indenture Act and together with its immediate parent maintain a combined
capital and surplus of at least $50,000,000, be subject to supervision or
examination by Federal or State authority and have its Corporate Trust Office in
the City of            .  If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

          SECTION 6.09.  Resignation and Removal; Appointment of Successor.  (a)
                         --------------------------------------------------
No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee under Section 6.10.

          (b)  The Trustee may resign at any time by giving written notice
thereof to the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

          (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the

                                                                              47

Outstanding Debentures, delivered to the Trustee and to the Company.

          (d)  If at any time:

          (i) the Trustee shall cease to be eligible under Section 6.08 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder; or

         (ii) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 5.14, any Holder who has been a bona fide
Holder of a Debenture for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee.  If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Debentures
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the
successor Trustee and supersede the successor Trustee appointed by the Company.
If no successor Trustee shall have been so appointed by the Company or the
Holders and accepted appointment in the manner hereinafter provided, the Trustee
or any Holder who has been a bona fide Holder of a Debenture for at least six
months may, on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee.

          (f)  The Company shall give notice of each resignation and each
removal of the Trustee and each

appointment of a successor Trustee by mailing written notice of such event by
first-class mail, postage prepaid, to all Holders as their names and addresses
appear in the Debenture Register.  Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

          SECTION 6.10.  Acceptance of Appointment by Successor.  Every
                         ---------------------------------------       
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges pursuant to
Section 6.07, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.  Upon request of any such successor
Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.  Any retiring trustee shall, nevertheless, retain a lien on
all property or funds held or collected by such trustee to secure any amounts
then due pursuant to the provisions of Section 6.07.

          Upon acceptance of appointment by a successor Trustee as provided in
this Section, the Company shall cause such successor Trustee to mail notice of
succession of such Trustee hereunder to all Holders of Debentures as the names
and addresses of such Holders appear on the Debenture Register.

          No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be eligible under this Article
and qualified under Section 3.10(b) of the Trust Indenture Act.

          SECTION 6.11.  Merger, Conversion, Consolidation or Succession to
                         --------------------------------------------------
Business.  Any corporation or national banking association into which the

Trustee may be merged or converted or with which it may be consolidated, or any
corporation or national banking association resulting from

any merger, conversion or consolidation to which the Trustee shall be a party,
or any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder;
provided such corporation or national banking association shall be otherwise
- --------                                                                    
eligible under this Article and qualified under Section 3.10(b) of the Trust
Indenture Act, without the execution or filing of any paper or any further act
on the part of any of the parties hereto.  In case any Debentures shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Debentures so authenticated with
the same effect as if such successor Trustee had itself authenticated such
Debentures.

          SECTION 6.12.  Preferential Collection of Claims Against Company.  The
                         --------------------------------- ----------------     
Trustee is subject to Section 311(a) and (b) of the Trust Indenture Act.  Any
Trustee that has resigned or been removed shall be subject to Section 311(a) and
(b) of the Trust Indenture Act to the extent indicated therein.

          SECTION 6.13.  Appointment of Authenticating Agent.  The Trustee may
                         ------------------------------------                 
appoint an Authenticating Agent or Agents which shall be authorized to act on
behalf of the Trustee to authenticate Debentures issued upon exchange,
registration of transfer or partial redemption or repurchase thereof or pursuant
to Section 3.06, and Debentures so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder.  Wherever reference is made in this
Indenture to the authentication and delivery of Debentures by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said
<PAGE>
 
                                                                              50

supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

          Any corporation or national banking association into which an
Authenticating Agent may be merged or converted or with which it may be
consolidated or any corporation or national banking association resulting from
any merger, conversion or consolidation to which such Authenticating Agent shall
be a party, or any corporation succeeding to the corporate agency or corporate
trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent; provided such corporation or national banking association
                      --------                                                 
shall be otherwise eligible under this Section, without the execution or filing
of any paper or any further act on the part of the Trustee or the Authenticating
Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders as their
names and addresses appear in the Debenture Register.  Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent herein.  No
successor Authenticating Agent shall be appointed unless eligible under the
provisions of his Section.

          The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

          If an appointment is made pursuant to this Section, the Debentures may
have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternate certificate of authentication in the following
form:

               Holders' Lists and Reports by Trustee and Company
               -------------------------------------------------

          SECTION 7.01.  Company To Furnish Trustee Names and Addresses of
                         -------------------------------------------------
Holders.  The Company will furnish or cause to be furnished to the Trustee:
- --------                                                                   

          (a) semiannually, not more than 15 days after each Regular Record
     Date, a list, in such form as the Trustee may reasonably require, of the
     names and addresses of the Holders as of such Regular Record Date, and

          (b) at such other times as the Trustee may request in writing, within
     30 days after the receipt by the Company of any such request, a list of
     similar form and content as of a date not more than 15 days prior to the
     time such list is furnished;

excluding from any such list names and addresses received by the Trustee in its

capacity as Debenture Registrar.

          SECTION 7.02.  Preservation of Information Communications to Holders.
                         ------------------------------------------------------ 
(a)  The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.01 and the names and
addresses of Holders received by the Trustee in its capacity as Debenture
Registrar.  The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished.

          (b)  If three or more Holders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Debenture for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Holders with respect to their
rights under this Indenture or under the Debentures and is accompanied by a copy
of the form of proxy or other communication which such applicants propose to
transmit, then the Trustee shall,

                                                                              53

within five business days after the receipt of such application, at its
election, either:

          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), or

         (ii) inform such applicants as to the approximate number of Holders
     whose names and addresses appear in the information preserved at the time
     by the Trustee in accordance with Section 7.02(a), and as to the
     approximate cost of mailing to such Holders the form of proxy or other
     communication, if any, specified in such application.

          If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 7.02(a) a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law.  Such written statement shall
specify the basis of such opinion.  If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Holders with reasonable promptness
after the entry of such order and the renewal of such tender; otherwise the
Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

          (c)  Every Holder of Debentures, by receiving and holding the same,
agrees with the Company and the Trustee that neither the Company nor the Trustee
nor any agent of

either of them shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Holders in accordance with
Section 7.02(b), regardless of the source from which such information was

          (b) give the Trustee notice of any default by the Company (or any
     other obligor upon the Debentures) in the making of any payment of
     principal (and premium, if any) or interest; and

          (c) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or

desirable in the conduct of its business and not disadvantageous in any material
respect to the Holders.

          SECTION 10.06.  Payment of Taxes and Other Claims.  The Company will
                          ----------------------------------                  
pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or upon the income, profits or property of the Company,
and (b) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company; provided, however,

that the Company shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

          SECTION 10.07.  Waiver of Certain Covenants.  The Company may omit in
                          ----------------------------                         
any particular instance to comply with any covenant or condition set forth in
Sections 10.04 to 10.06, inclusive, if before the time for such compliance the
Holders of at least a majority in principal amount of the Outstanding Debentures
shall, by Act of such Holders, either waive such compliance in such instance or
generally waive compliance with such covenant or condition, but no such waiver
shall extend to or affect such covenant or condition except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the Company and the duties of the Trustee in respect of any such covenant or
condition shall remain in full force and effect.

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

          SECTION 11.01.  Right of Redemption.  The Debentures may be redeemed
                          --------------------                                
at the election of the Company, as a whole or from time to time in part, at any
time, at the Redemption Prices specified in the form of Debenture hereinbefore
set forth for redemptions, together with accrued interest to the Redemption
Date; provided, however, that the Company may not redeem any of the Debentures
      --------  -------

provision of this

Indenture, shall be made in accordance with such provision and this Article.

          SECTION 11.03.  Election To Redeem; Notice to Trustee.  The election
                          --------------------------------------              
of the Company to redeem any Debentures pursuant to Section 11.01 shall be
evidenced by a Board Resolution.  In case of any redemption at the election of
the Company of less than all the Debentures, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee) notify the Trustee of such Redemption Date and
of the principal amount of Debentures to be redeemed.

          SECTION 11.04.  Selection by Trustee of Debentures To Be Redeemed.  If
                          --------------------------------------------------    
less than all the Debentures are to be redeemed the particular Debentures to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Debentures not previously called for
redemption, pro rata or by lot or by such other method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
portions (equal to $1,000 or any integral multiple thereof) of the principal
amount of Debentures of a denomination larger than $1,000.

          If any Debenture selected for partial redemption is converted in part
before termination of the conversion right with respect to the portion of the
Debenture so selected, the converted portion of such Debenture shall be deemed
(so far as may be) to be the portion selected for redemption.  Debentures which
have been converted during a selection of Debentures to be redeemed shall be
treated by the Trustee as Outstanding for the purpose of such selection.

          The Trustee shall promptly notify the Company and the Debenture
Registrar in writing of the Debentures selected for redemption and, in the case
of any Debentures selected for partial redemption, the principal amount thereof
to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Debentures shall relate,
in the case of any Debentures redeemed or to be redeemed only in part, to the
portion of the principal amount of such Debenture which has been or is to be
redeemed.

          SECTION 11.05.  Notice of Redemption.  Notice of redemption shall be
                          ---------------------                               
given by first-class mail, postage prepaid, mailed not less than 30 nor more
than 60 days prior to the Redemption Date, to each Holder of Debentures to be
redeemed, at his address appearing in the Debenture Register.

          All notices of redemption shall state:

          (1) the Redemption Date;

          (2) the Redemption Price;

          (3) if less than all the Outstanding Debentures
     are to be redeemed, the identification (and, in the case of partial
     redemption, the principal amounts) of the particular Debentures to be
     redeemed;

          (4) that on the Redemption Date the Redemption Price, together with
     (unless the Redemption Date shall be an Interest Payment Date) interest
     accrued and unpaid to the Redemption Date, will become due and payable upon
     each such Debenture to be redeemed and that interest thereon will cease to
     accrue on and after said date;

          (5) the conversion price, the date on which the right to convert the
     principal of the Debentures to be redeemed will terminate and the place or
     places where such Debentures may be surrendered for conversion; and

          (6) the place or places where such Debentures are to be surrendered
     for payment of the Redemption Price.

          Notice of redemption of Debentures to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

          SECTION 11.06.  Deposit of Redemption Price.  Prior to any Redemption
                          ----------------------------                         
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust) an
amount of money sufficient to pay the Redemption Price of  and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on all the
Debentures which are to be redeemed on that date other than any Debentures
<PAGE>
 
                                                                              67

called for redemption on that date which have been converted prior to the date
of such deposit.

          If any Debenture called for redemption is converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held in
trust for the redemption of such Debenture shall (subject to any right of the
Holder of such Debenture or any Predecessor Debenture to receive interest as
provided in the last paragraph of Section 3.07) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.

          SECTION 11.07.  Debentures Payable on Redemption Date.  Notice of
                          --------------------------------------           
redemption having been given as aforesaid, the Debentures so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Debentures shall cease to bear interest.  Upon surrender of any such Debenture
for redemption in accordance with said notice, such Debenture shall be paid by
the Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that installments of interest whose Stated
                 --------  -------                                            
Maturity is on or prior to the Redemption Date shall be payable to the Holders
of such Debentures, or one or more Predecessor Debentures, registered as such at
the close of business on the relevant Record Dates according to their terms and
the provisions of Section 3.07.

          If any Debenture called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Debenture.

          SECTION 11.08.  Debentures Redeemed in Part.  Any Debenture which is
                          ----------------------------                        
to be redeemed only in part shall be surrendered at any office or agency of the
Company designated for that purpose (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company, the Trustee and the Debenture Registrar duly
executed by, the Holder thereof or his attorney duly authorized in writing), and
the Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Debenture without service charge, a new Debenture or

                                                                              68

Debentures, of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Debenture so surrendered.

                            Conversion of Debentures
                            ------------------------

          SECTION 12.01.  Conversion Privilege and Conversion Price.  Subject to
                          ------------------------------------------            
and upon compliance with the provisions of this Article, at the option of the
Holder thereof, any Debenture or any portion of the principal amount thereof
which is $1,000 or an integral multiple of $1,000 may be converted at the
principal amount thereof, or of such portion thereof, into fully paid and
nonassessable shares (calculated as to each conversion to the nearest 1/100 of a
share) of Common Stock of the Company, at the conversion price, determined as
hereinafter provided, in effect at the time of conversion.  Such conversion
right shall expire at the close of business on             , 2005.  In case a
Debenture or portion thereof is called for redemption, such conversion right in
respect of the Debenture or portion so called shall expire at the close of
business on the Business Day preceding the Redemption Date, unless the Company
defaults in making the payment due upon redemption.

          The price at which shares of Common Stock shall be delivered upon
conversion (herein called the "Conversion Price") shall be initially $      per
share of Common Stock.  The Conversion Price shall be adjusted in certain
instances as provided in paragraphs (1), (2), (3), (4) and (8) of Section 12.04.

          SECTION 12.02.  Exercise of Conversion Privilege.  In order to
                          ---------------------------------             
exercise the conversion privilege, the Holder of any Debenture to be converted
shall surrender such Debenture, duly endorsed or assigned to the Company or in
blank, at any office or agency of the Company maintained for that purpose,
accompanied by written notice to the Company at such office or agency that the
Holder elects to convert such Debenture or, if less than the entire principal
amount thereof is to be converted, the portion thereof to be converted.  In
connection with the exercise of the conversion privilege by a Holder prior to a
Redemption Date, a Holder's right to exercise his conversion privilege shall

                                                                              69

terminate at the close of business on the Business Day prior to the Redemption
Date.  Debentures surrendered for conversion during the period from the close of
business on any Regular Record Date next preceding any Interest Payment Date to
the opening of business on such Interest Payment Date shall (except in the case
of Debentures or portions thereof which have been called for redemption on a
Redemption Date within such period) be accompanied by payment in New York
Clearing House funds or other funds acceptable to the Company of an amount equal
to the interest payable on such Interest Payment Date on the principal amount of
Debentures being surrendered for conversion.  Except as provided in the
preceding sentence and subject to the last paragraph of Section 3.07, no payment
or adjustment shall be made upon any conversion on account of any interest
accrued on the Debentures surrendered for conversion or on account of any
dividends on the Common Stock issued upon conversion.

          Debentures shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Debentures for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Debentures as Holders shall cease, and the person or persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time.  As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 12.03.

          In the case of any Debenture which is converted in part only, upon
such conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Debenture or
Debentures of authorized denominations in aggregate principal amount equal to
the unconverted portion of the principal amount of such Debenture.

          SECTION 12.03.  Fractions of Shares.  No fractional shares of Common
                          --------------------                                
Stock shall be issued upon the conversion of Debentures.  If more than one
Debenture shall be surrendered for conversion at one time by the same Holder,
the number of full shares which shall be issuable upon conversion thereof shall
be computed on the basis of
<PAGE>
 
                                                                              70

the aggregate principal amount of Debentures (or specified portions thereof) so
surrendered.  Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of any Debenture or Debentures (or
specified portions thereof), the Company shall pay a cash adjustment in respect
of such fraction in an amount equal to the same fraction of the closing price
per share of Common Stock at the close of business on the Business Day prior to
the day of conversion (determined as provided in the second sentence of
paragraph (6) of Section 12.04).

          SECTION 12.04.  Adjustment of Conversion Price.  The Conversion Price
                          -------------------------------                      
shall be adjusted from time to time by the Company as follows:

          (a)  If the Company shall hereafter pay a dividend or make a
     distribution to all holders of the outstanding Common Stock in shares of
     Common Stock, the Conversion Price in effect at the opening of business on
     the date following the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such Conversion Price by a fraction of which the numerator
     shall be the number of shares of Common Stock outstanding at the close of
     business on the Record Date (as defined in Section 12.04(g)) fixed for such
     determination and the denominator shall be the sum of such number of shares
     and the total number of shares constituting such dividend or other
     distribution, such reduction to become effective immediately after the
     opening of business on the day following the Record Date.  If any dividend
     or distribution of the type described in this Section 12.04(a) is declared
     but not so paid or made, the Conversion Price shall again be adjusted to
     the Conversion Price which would then be in effect if such dividend or
     distribution had not been declared.

          (b)  If the Company shall issue rights or warrants to all holders of
     its outstanding shares of Common Stock entitling them to subscribe for or
     purchase shares of Common Stock at a price per share less than the Current
     Market Price (as defined in Section 12.04 (g)) on the Record Date fixed for
     the determination of stockholders entitled to receive such rights or
     warrants, the Conversion Price shall be adjusted so that the same shall
     equal the price determined by multiplying the Conversion Price in effect at
     the
<PAGE>
 
                                                                              71

     opening of business on the date after such Record Date by a fraction of
     which the numerator shall be the number of shares of Common Stock
     outstanding at the close of business on the Record Date plus the number of
     shares of Common Stock which the aggregate offering price of the total
     number of shares so offered would purchase at such Current Market Price and
     of which the denominator shall be the number of shares of Common Stock
     outstanding at the close of business on the Record Date plus the total
     number of additional shares of Common Stock so offered for subscription or
     purchase.  Such adjustment shall become effective immediately after the
     opening of business on the day following the Record Date fixed for
     determination of stockholders entitled to receive such rights or warrants.
     To the extent that shares of Common Stock are not delivered pursuant to
     such rights or warrants, upon the expiration or termination of such rights
     or warrants the Conversion Price shall again be adjusted to be the
     Conversion Price which would then be in effect had the adjustments made
     upon the issuance of such rights or warrants been made on the basis of
     delivery of only the number of shares of Common Stock actually delivered.
     If such rights or warrants are not so issued, the Conversion Price shall
     again be adjusted to be the Conversion price which would then be in effect
     if such date fixed for the determination of stockholders entitled to
     receive such rights or warrants had not been fixed.  In determining whether
     any rights or warrants entitle the holders to subscribe for or purchase
     shares of Common Stock at less than such Current Market Price, and in
     determining the aggregate offering price of such shares of Common Stock,
     there shall be taken into account any consideration received for such
     rights or warrants, with the value of such consideration, if other than
     cash, to be determined by the Board of Directors.

          (c)  If the outstanding shares of Common Stock shall be subdivided
     into a greater number of shares of Common Stock, the Conversion Price in
     effect at the opening of business on the day following the day upon which
     such subdivision becomes effective shall be proportionately reduced, and,
     conversely, if the outstanding shares of Common Stock shall be combined
     into a smaller number of shares of Common Stock, the Conversion Price in
     effect at the opening of business on the day following the day upon which
     such
<PAGE>
 
                                                                              72

     combination becomes effective shall be proportionately increased, such
     reduction or increase, as the case may be, to become effective immediately
     after the opening of business on the day following the day upon which such
     subdivision or combination becomes effective.

          (d)  If the Company shall, by dividend or otherwise, distribute to all
     holders of its Common Stock shares of any class of capital stock of the
     Company (other than any dividends or distributions to which Section
     12.04(a) applies) or evidences of its indebtedness, cash or other assets
     (including securities, but excluding any rights or warrants of a type
     referred to in Section 12.04(b) and dividends and distributions paid
     exclusively in cash and excluding any capital stock, evidences of
     indebtedness, cash or assets distributed upon a merger or consolidation to
     which Section 12.10 applies) (the foregoing hereinafter in this Section
     12.04(d) called the "Securities"), then, in each such case, the Conversion
     Price shall be reduced so that the same shall be equal to the price
     determined by multiplying the Conversion Price in effect immediately prior
     to the close of business on the Record Date (as defined in Section
     12.04(g)) with respect to such distribution by a fraction of which the
     numerator shall be the Current Market Price (determined as provided in
     Section 12.04(g)) on such date less the fair market value (as determined by
     the Board of Directors, whose determination shall be conclusive and
     described in a resolution of the Board of Directors) on such date of the
     portion of the Securities so distributed applicable to one share of Common
     Stock and the denominator shall be such Current Market Price, such
     reduction to become effective immediately prior to the opening of business
     on the day following the Record Date; provided, however, that, in the event
                                           --------  -------                    
     the then fair market value (as so determined) of the portion of the
     Securities so distributed applicable to one share of Common Stock is equal
     to or greater than the Current Market Price on the Record Date, in lieu of
     the foregoing adjustment, adequate provision shall be made so that each
     holder of Debentures shall have the right to receive upon conversion of a
     Debenture (or any portion thereof) the amount of Securities such holder
     would have received had such holder converted such Debenture (or portion
     thereof) immediately prior to such Record Date.  If such dividend or
     distribution is not so paid or made, the Conversion Price shall again

                                                                              73

     be adjusted to be the Conversion Price which would then be in effect if
     such dividend or distribution had not been declared.  If the Board of
     Directors determines the fair market value of any distribution for purposes
     of this Section 12.04(d) by reference to the actual or when issued trading
     market for any securities comprising all or part of such distribution, it
     must in doing so consider the prices in such market over the same period
     used in computing the Current Market Price pursuant to Section 12.04(g) to
     the extent possible.

          Rights or warrants distributed by the Company to all holders of Common
     Stock entitling the holders thereof to subscribe for or purchase shares of
     the Company's capital stock (either initially or under certain
     circumstances), which rights or warrants, until the occurrence of a
     specified event or events ("Trigger Event"):  (i) are deemed to be
     transferred with such shares of Common Stock; (ii) are not exercisable; and
     (iii) are also issued in respect of future issuances of Common Stock, shall
     be deemed not to have been distributed for purposes of this Section
     12.04(d) (and no adjustment to the Conversion Price under this Section
     12.04(d) shall be required) until the occurrence of the earliest Trigger
     Event, whereupon such rights and warrants shall be deemed to have been
     distributed and an appropriate adjustment to the Conversion Price under
     this Section 12.04(d) shall be made.  If any such rights or warrants,
     including any such existing rights or warrants distributed prior to the
     date of this Indenture, are subject to subsequent events, upon the
     occurrence of each of which such rights or warrants shall become
     exercisable to purchase different securities, evidences of indebtedness or
     other assets, then the occurrence of each such event shall be deemed to be
     such date of issuance and record date with respect to new rights or
     warrants (and a termination or expiration of the existing rights or
     warrants without exercise by the holder thereof).  In addition, in the
     event of any distribution (or deemed distribution) of rights or warrants,
     or any Trigger Event with respect thereto, that was counted for purposes of
     calculating a distribution amount for which an adjustment to the Conversion
     Price under this Section 12.04 was made, (1) in the case of any such rights
     or warrants which shall all have been redeemed or repurchased without
     exercise by any holders thereof, the Conversion Price shall be readjusted
     upon such

                                                                              74

     final redemption or repurchase to give effect to such distribution or
     Trigger Event, as the case may be, as though it were a cash distribution,
     equal to the per share redemption or repurchase price received by a holder
     or holders of Common Stock with respect to such rights or warrants
     (assuming such holder had retained such rights or warrants), made to all
     holders of Common Stock as of the date of such redemption or repurchase,
     and (2) in the case of such rights or warrants which shall have expired or
     been terminated without exercise by any holders thereof, the Conversion
     Price shall be readjusted as if such rights and warrants had not been
     issued.

          Notwithstanding any other provision of this Section 12.04(d) to the
     contrary, rights, warrants, evidences of indebtedness, other securities,
     cash or other assets (including, without limitation, any rights distributed
     pursuant to any stockholder rights plan) shall be deemed not to have been
     distributed for purposes of this Section 12.04(d) if the Company makes
     proper provision so that each holder of Debentures who converts a Debenture
     (or any portion thereof) after the date fixed for determination of
     stockholders entitled to receive such distribution shall be entitled to
     receive upon such conversion, in addition to the shares of Common Stock
     issuable upon such conversion, the amount and kind of such distributions
     that such holder would have been entitled to receive if such holder had,
     immediately prior to such determination date, converted such Debenture into
     Common Stock.

          For purposes of this Section 12.04(d) and Sections 12.04(a) and (b),
     any dividend or distribution to which this Section 12.04(d) is applicable
     that also includes shares of Common Stock, or rights or warrants to
     subscribe for or purchase shares of Common Stock to which Section 12.04(b)
     applies (or both), shall be deemed instead to be (1) a dividend or
     distribution of the evidences of indebtedness, assets, shares of capital
     stock, rights or warrants other than such shares of Common Stock or rights
     or warrants to which Section 12.04(b) applies (and any Conversion Price
     reduction required by this Section 12.04(d) with respect to such dividend
     or distribution shall then be made) immediately followed by (2) a dividend
     or distribution of such shares of Common Stock or such rights or warrants
     (and any further Conversion Price
<PAGE>
 
                                                                              75

     reduction required by Sections 12.04(a) and (b) with respect to such
     dividend or distribution shall then be made), except that (a) the Record
     Date of such dividend or distribution shall be substituted as "the date
     fixed for the determination of stockholders entitled to receive such
     dividend or other distribution", "Record Date fixed for such determination"
     and "Record Date" within the meaning of Section 12.04(a) and as "the date
     fixed for the determination of stockholders entitled to receive such rights
     or warrants", "the Record Date fixed for the determination of the
     stockholders entitled to receive such rights or warrants" and "such Record
     Date" within the meaning of Section 12.04(b), and (b) any shares of Common
     Stock included in such dividend or distribution shall not be deemed
     "outstanding at the close of business on the date fixed for such
     determination" within the meaning of Section 12.04(a).

          (e)  If the Company shall, by dividend or otherwise, distribute to all
     holders of its Common Stock cash (excluding any cash that is distributed
     upon a merger or consolidation to which Section 12.10 applies or as part of
     a distribution referred to in Section 12.04(d)) in an aggregate amount
     that, combined together with (1) the aggregate amount of any other such
     distributions to all holders of its Common Stock made exclusively in cash
     within the 12 months preceding the date of payment of such distribution,
     and in respect of which no adjustment pursuant to this Section 12.04(e) has
     been made, and (2) the aggregate of any cash plus the fair market value (as
     determined by the Board of Directors, whose determination shall be
     conclusive and described in a resolution of the Board of Directors) of
     consideration payable in respect of any tender offer by the Company or any
     of its subsidiaries for all or any portion of the Common Stock concluded
     within the 12 months preceding the date of payment of such distribution,
     and in respect of which no adjustment pursuant to Section 12.04(f) has been
     made, exceeds 10% of the product of the Current Market Price (determined as
     provided in Section 12.04(g)) on the Record Date with respect to such
     distribution times the number of shares of Common Stock outstanding on such
     date, then, and in each such case, immediately after the close of business
     on such date, the Conversion Price shall be reduced so that the same shall
     equal the price determined by multiplying the
<PAGE>
 
                                                                              76

     Conversion Price in effect immediately prior to the close of business on
     such Record Date by a fraction (i) the numerator of which shall be equal to
     the Current Market Price on the Record Date less an amount equal to the
     quotient of (x) the excess of such combined amount over such 10% and (y)
     the number of shares of Common Stock outstanding on the Record Date and
     (ii) the denominator of which shall be equal to the Current Market Price on
     such Record Date; provided, however, that, if the portion of the cash so
                       --------  -------                                     
     distributed applicable to one share of Common Stock is equal to or greater
     than the Current Market Price of the Common Stock on the Record Date, in
     lieu of the foregoing adjustment, adequate provision shall be made so that
     each holder of Debentures shall have the right to receive upon conversion
     of a Debenture (or any portion thereof) the amount of cash such holder
     would have received had such holder converted such Debenture (or portion
     thereof) immediately prior to such Record Date.  If such dividend or
     distribution is not so paid or made, the Conversion Price shall again be
     adjusted to be the Conversion Price which would then be in effect if such
     dividend or distribution had not been declared.  Any cash distribution to
     all holders of Common Stock as to which the Company makes the election
     permitted by Section 12.04(m) and as to which the Company has complied with
     the requirements of such Section shall be treated as not having been made
     for all purposes of this Section 12.04(e).

          (f)  If a tender offer made by the Company or any of its subsidiaries
     for all or any portion of the Common Stock expires and such tender offer
     (as amended upon the expiration thereof) requires the payment to
     stockholders (based on the acceptance (up to any maximum specified in the
     terms of the tender offer) of Purchased Shares (as defined below)) of an
     aggregate consideration having a fair market value (as determined by the
     Board of Directors, whose determination shall be conclusive and described
     in a resolution of the Board of Directors) that, combined together with (1)
     the aggregate of the cash plus the fair market value (as determined by the
     Board of Directors, whose determination shall be conclusive and described
     in a resolution of the Board of Directors), as of the expiration of such
     tender offer, of consideration payable in respect of any other tender
     offers, by the Company or any of its subsidiaries for all or any
<PAGE>
 
                                                                              77

     portion of the Common Stock expiring within the 12 months preceding the
     expiration of such tender offer and in respect of which no adjustment
     pursuant to this Section 12.04(f) has been made and (2) the aggregate
     amount of any distributions to all holders of the Common Stock made
     exclusively in cash within 12 months preceding the expiration of such
     tender offer and in respect of which no adjustment pursuant to Section
     12.04(e) has been made, exceeds 10% of the product of the Current Market
     Price (determined as provided in Section 12.04(g)) as of the last time (the
     "Expiration Time") tenders could have been made pursuant to such tender
     offer (as it may be amended) times the number of shares of Common Stock
     outstanding (including any tendered shares) at the Expiration Time, then,
     and in each such case, immediately prior to the opening of business on the
     day after the date of the Expiration Time, the Conversion Price shall be
     adjusted so that the same shall equal the price determined by multiplying
     the Conversion Price in effect immediately prior to the close of business
     on the date of the Expiration Time by a fraction of which the numerator
     shall be the number of shares of Common Stock outstanding (including any
     tendered shares) at the Expiration Time multiplied by the Current Market
     Price of the Common Stock on the trading day next succeeding the Expiration
     Time and the denominator shall be the sum of (x) the fair market value
     (determined as aforesaid) of the aggregate consideration payable to
     stockholders based on the acceptance (up to any maximum specified in the
     terms of the tender offer) of all shares validly tendered and not withdrawn
     as of the Expiration Time (the shares deemed so accepted, up to any such
     maximum, being referred to as the "Purchased Shares") and (y) the product
     of the number of shares of Common Stock outstanding (less any Purchased
     Shares) at the Expiration Time and the Current Market Price of the Common
     Stock on the Trading Day next succeeding the Expiration Time, such
     reduction (if any) to become effective immediately prior to the opening of
     business on the day following the Expiration Time.  If the Company is
     obligated to purchase shares pursuant to any such tender offer, but the
     Company is permanently prevented by applicable law from effecting any such
     purchases or all such purchases are rescinded, the Conversion Price shall
     again be adjusted to be the Conversion Price which would then be in effect
     if such tender offer had not been made.  If the application of
<PAGE>
 
                                                                              78

     this Section 12.04(f) to any tender offer would result in an increase in
     the Conversion Price, no adjustment shall be made for such tender offer
     under this Section 12.04(f).

          (g)  For purposes of this Section 12.04, the following terms shall
     have the meaning indicated:

               (i)  "closing price" with respect to any securities on any day
          means the closing price on such day or, if no such sale takes place on
          such day, the average of the reported high and low prices on such day,
          in each case on The Nasdaq  National Market or the New York Stock
          Exchange, as applicable, or, if such security is not listed or
          admitted to trading on such national market or exchange, on the
          principal national securities exchange or quotation system on which
          such security is quoted or listed or admitted to trading, or, if not
          quoted or listed or admitted to trading on any national securities
          exchange or quotation system, the average of the high and low prices
          of such security on the over-the-counter market on the day in question
          as reported by the National Quotation Bureau Incorporated or a similar
          generally accepted reporting service, or, if not so available, in such
          manner as furnished by any New York Stock Exchange member firm
          selected from time to time by the Board of Directors for that purpose,
          or a price determined in good faith by the Board of Directors, whose
          determination shall be conclusive and described in a resolution of the
          Board of Directors.

               (ii)  "Current Market Price" means the average of the daily
          closing prices per share of Common Stock for the 10 consecutive
          trading days immediately prior to the date in question; provided,
                                                                  -------- 
          however, that (A) if the "ex" date (as hereinafter defined) for any
          -------                                                            
          event (other than the issuance or distribution requiring such
          computation) that requires an adjustment to the Conversion Price
          pursuant to Section 12.04(a), (b), (c), (d), (e) or (f) occurs during
          such 10 consecutive trading days, the closing price for each trading
          day prior to the "ex" date for such other event shall be adjusted by
          multiplying such closing price by the same fraction by which the
<PAGE>
 
                                                                              79

          Conversion Price is so required to be adjusted as a result of such
          other event, (B) if the "ex" date for any event (other than the
          issuance or distribution requiring such computation) that requires an
          adjustment to the Conversion Price pursuant to Section 12.04(a), (b),
          (c), (d), (e) or (f) occurs on or after the "ex" date for the issuance
          or distribution requiring such computation and prior to the day in
          question, the closing price for each trading day on and after the "ex"
          date for such other event shall be adjusted by multiplying such
          closing price by the reciprocal of the fraction by which the
          Conversion Price is so required to be adjusted as a result of such
          other event and (C) if the "ex" date for the issuance or distribution
          requiring such computation is prior to the day in question, after
          taking into account any adjustment required pursuant to clause (A) or
          (B) of this proviso, the closing price for each trading day on or
          after such "ex" date shall be adjusted by adding thereto the amount of
          any cash and the fair market value (as determined by the Board of
          Directors in a manner consistent with any determination of such value
          for purposes of Section 12.04(d) or (f), whose determination shall be
          conclusive and described in a resolution of the Board of Directors) of
          the evidences of indebtedness, shares of capital stock or assets being
          distributed applicable to one share of Common Stock as of the close of
          business on the day before such "ex" date.  For purposes of any
          computation under Section 12.04(f), the Current Market Price on any
          date shall be deemed to be the average of the daily closing prices per
          share of Common Stock for such day and the next two succeeding trading
          days; provided, however, that, if the "ex" date for any event (other
                --------  -------                                             
          than the tender offer requiring such computation) that requires an
          adjustment to the Conversion Price pursuant to Section 12.04(a), (b),
          (c), (d), (e) or (f) occurs on or after the Expiration Time for the
          tender or exchange offer requiring such computation and prior to the
          day in question, the closing price for each trading day on and after
          the "ex" date for such other event shall be adjusted by multiplying
          such closing price by the reciprocal of the fraction by which the
          Conversion
<PAGE>
 
                                                                              80

          Price is so required to be adjusted as a result of such other event.
          For purposes of this paragraph, the term "ex" date (I) when used with
          respect to any issuance or distribution, means the first date on which
          the Common Stock trades regular way on the relevant exchange or in the
          relevant market from which the closing price was obtained without the
          right to receive such issuance or  distribution, (II) when used with
          respect to any subdivision or combination of shares of Common Stock,
          means the first date on which the Common Stock trades regular way on
          such exchange or in such market after the time at which such
          subdivision or combination becomes effective and (III) when used with
          respect to any tender or exchange offer means the first date on which
          the Common Stock trades regular way on such exchange or in such market
          after the Expiration Time of such offer.  Notwithstanding the
          foregoing, whenever successive adjustments to the Conversion Price are
          called for pursuant to this  Section 12.04, such adjustments shall be
          made to the Current Market Price as may be necessary or appropriate to
          effectuate the intent of this Section 12.04 and to avoid unjust or
          inequitable results, as determined in good faith by the Board of
          Directors.

               (iii)  "fair market value" shall mean the amount which a willing
          buyer would pay a willing seller in an arm's-length transaction.

                (iv)  "Record Date" shall mean, with respect to any dividend,
          distribution or other transaction or event in which the holders of
          Common Stock have the right to receive any cash, securities or other
          property or in which the Common Stock (or other applicable security)
          is exchanged for or converted into any combination of cash, securities
          or other property, the date fixed for determination of stockholders
          entitled to receive such cash, securities or other property (whether
          such date is fixed by the Board of Directors or by statute, contract
          or otherwise).

               (v)  "trading day" shall mean (A) if the applicable security is
          listed or admitted for trading on the New York Stock Exchange or
          another
<PAGE>
 
                                                                              81

          national securities exchange, a day on which the New York Stock
          Exchange or another national securities exchange is open for business,
          (B) if the applicable security is quoted on The Nasdaq National
          Market, a day on which trades may be made thereon or (c) if the
          applicable security is not so listed, admitted for trading or quoted,
          any day other than a Saturday or Sunday or a day on which banking
          institutions in the State of New York are authorized or obligated by
          law or executive order to close.

          (h)  The Company may make such reductions in the Conversion Price, in
     addition to those required by Sections 12.04(a), (b), (c), (d), (e) and
     (f), as the Board of Directors considers to be advisable to avoid or
     diminish any income tax to holders of Common Stock or rights to purchase
     Common Stock resulting from any dividend or distribution of stock (or
     rights to acquire stock) or from any event treated as such for income tax
     purposes.

          To the extent permitted by applicable law, the Company from time to
     time may reduce the Conversion Price by any amount for any period of time
     if the period is at least 20 days, the reduction is irrevocable during the
     period and the Board of Directors has made a determination that such
     reduction would be in the Company's best interests, which determination
     shall be conclusive and described in a resolution of the Board of
     Directors.  Whenever the Conversion Price is reduced pursuant to the
     preceding sentence, the Company shall mail to the holders of Debentures at
     their last addresses appearing on the register of holders maintained for
     that purpose a notice of the reduction at least 15 days prior to the date
     the reduced Conversion Price takes effect, and such notice shall state the
     reduced Conversion Price and the period during which it will be in effect.

          (i)  No adjustment in the Conversion Price shall be required unless
     such adjustment would require an increase or decrease of at least 1% in
     such price; provided, however, that any adjustments which by reason of this
                 --------  -------                                              
     Section 12.04(i) are not required to be made shall be carried forward and
     taken into account in any subsequent adjustment.  All calculations under
     this Article 12 shall be made by the Company and shall be

                                                                              82

     made to the nearest cent or to the nearest one-hundredth of a share, as the
     case may be.

          No adjustment need be made for a change in the par value or no par
     value of the Common Stock.

          (j)  Whenever the Conversion Price is adjusted as herein provided, the
     Company shall promptly file with the Trustee an Officers' Certificate
     setting forth the Conversion Price after such adjustment and setting forth
     a brief statement of the facts requiring such adjustment.  Promptly after
     delivery of such certificate, the Company shall prepare a notice of such
     adjustment of the Conversion Price setting forth the adjusted Conversion
     Price and the date on which each adjustment becomes effective and shall
     mail such notice of such adjustment of the Conversion Price to each holder
     of Debentures at such holder's last address appearing on the register of
     holders maintained for that purpose within 20 days of the effective date of
     such adjustment.  Failure to deliver such notice shall not affect the
     legality or validity of any such adjustment.

          (k)  In any case in which this Section 12.04 provides that an
     adjustment shall become effective immediately after a Record Date for an
     event, the Company may defer until the occurrence of such event issuing to
     the holder of any Debenture converted after such Record Date and before the
     occurrence of such event the additional shares of common Stock issuable
     upon such conversion by reason of the adjustment required by such event
     over and above the Common Stock issuable upon such conversion before giving
     effect to such adjustment.

          (l)  For purposes of this Section 12.04, the number of shares of
     common Stock at any time outstanding shall not include shares held in the
     treasury of the Company but shall include shares issuable in respect of
     scrip certificates issued in lieu of fractions of shares of Common Stock.
     The Company shall not pay any dividend or make any distribution on shares
     of Common Stock held in the treasury of the Company.

          (m)  In lieu of making any adjustment to the Conversion Price pursuant
     to Section 12.04(e), the

                                                                              83

     Company may elect to reserve an amount of cash for distribution to the
     holders of Debentures upon the conversion of the Debentures so that any
     such holder converting Debentures will receive upon such conversion, in
     addition to the shares of Common Stock and other items to which such holder
     is entitled, the full amount of cash which such holder would have received
     if such holder had, immediately prior to the Record Date for such
     distribution of cash, converted its Debentures into Common Stock, together
     with any interest accrued with respect to such amount, in accordance with
     this Section 12.04(m).  The Company may make such election by providing an
     Officers' Certificate to the Trustee to such effect on or prior to the
     payment date for any such distribution and depositing with the Trustee on
     or prior to such date an amount of cash equal to the aggregate amount that
     the holders of Debentures would have received if such holders had,
     immediately prior to the Record Date for such distribution, converted all
     the Debentures into Common Stock.  Any such funds so deposited by the
     Company with the Trustee shall be invested by the Trustee in U.S.
     Government Obligations with a maturity not more than three months from the
     date of issuance.  Upon conversion of Debentures by a holder thereof, such
     holder shall be entitled to receive, in addition to the Common Stock
     issuable upon conversion, an amount of cash equal to the amount such holder
     would have received if such holder had, immediately prior to the Record
     Date for such distribution, converted its Debentures into Common Stock,
     along with such holder's pro rata share of any accrued interest earned as a
     consequence of the investment of such funds.  Promptly after making an
     election pursuant to this Section 12.04(m), the Company shall give or shall
     cause to be given notice to all holders of Debentures of such election,
     which notice shall state the amount of cash per $1,000 principal amount of
     Debentures such holders shall be entitled to receive (excluding interest)
     upon conversion of the Debentures as a consequence of the Company having
     made such election.

          SECTION 12.05.  Notice of Adjustment of Conversion Price.  Whenever
                          -----------------------------------------          
the conversion price is adjusted as herein provided:

          (a) the Company shall compute the adjusted conversion price in
     accordance with Section 12.04 and
<PAGE>
 
                                                                              84

     shall prepare a certificate signed by any Vice President or the Treasurer
     of the Company setting forth the adjusted conversion price and showing in
     reasonable detail the facts upon which such adjustment is based and the
     effective date of such adjustment, and such certificate shall forthwith be
     filed at each office or agency maintained for the purpose of conversion of
     Debentures; and

          (b) a notice stating that the conversion price has been adjusted and
     setting forth the adjusted conversion price shall, as soon as practicable,
     be mailed by the Company to all Holders at their last addresses as they
     shall appear in the Debenture Register.

          SECTION 12.06.  Notice of Certain Corporate Action.  In case:
                          -----------------------------------          

          (a) the Company shall declare a dividend (or any other distribution)
     on its Common Stock payable otherwise than in cash out of its earned
     surplus; or

          (b) the Company shall authorize the granting to the holders of its
     Common Stock of rights or warrants to subscribe for or purchase any shares
     of capital stock of any class or of any other rights; or

          (c) of any reclassification of the Common Stock of the Company (other
     than a subdivision or combination of its outstanding shares of Common
     Stock), or of any consolidation or merger to which the Company is a party
     and for which approval of any stockholders of the Company is required, or
     the sale or transfer of all or substantially all the assets of the Company;
     or

          (d) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company;

then the Company shall cause to be filed with the Trustee and at each office or
agency maintained for the purpose of conversion of Debentures, and shall cause
to be mailed to all Holders at their last addresses as they shall appear in the
Debenture Register, at least 20 days (or 10 days in any case specified in clause
(a) or (b) above) prior to the applicable date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, rights or warrants, or, if a record is not to be taken,
the date as of which the
<PAGE>
 
                                                                              85

holders of Common Stock of record to be entitled to such dividend, distribution,
rights or warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of Common Stock of record shall be entitled to
exchange their shares of Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.  Failure to give the notice requested by
this Section or any defect therein shall not affect the legality or validity of
any dividend, distribution, right, warrant, reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up, or the vote upon
any such action.

          SECTION 12.07.  Company To Reserve Common Stock.  The Company shall at
                          --------------------------------                      
all times reserve and keep available, free from preemptive rights, out of its
authorized but unissued Common Stock, for the purpose of effecting the
conversion of Debentures, the full number of shares of Common Stock then
issuable upon the conversion of all outstanding Debentures.

          SECTION 12.08.  Taxes on Conversions.  The Company will pay any and
                          ---------------------                              
all taxes that may be payable in respect of the issue or delivery of shares of
Common Stock on conversion of Debentures pursuant hereto.  The Company shall
not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of shares of Common Stock in a name
other than that of the Holder of the Debenture or Debentures to be converted,
and no such issue or delivery shall be made unless and until the person
requesting such issue has paid to the Company the amount of any such tax, or has
established to the satisfaction of the Company that such tax has been paid.

          SECTION 12.09.  Covenant as to Common Stock.  The Company covenants
                          ----------------------------                       
that all shares of Common Stock which may be issued upon conversion of
Debentures will upon issue be duly and validly issued and fully paid and
nonassessable and, except as provided in Section 12.08, the Company will pay all
taxes, liens and charges with respect to the issue thereof.

          SECTION 12.10.  Provisions in Case of Consolidation, Merger or
                          ----------------------------------------------
Conveyance or Transfer of Properties and Assets.  In case of any consolidation
- ------------------------------------------------                              
of the Company with, or merger of the Company into, any other corporation, or in
case of any merger of another corporation into the Company (other than a merger
which does not result in any reclassification, conversion, exchange or
cancelation of outstanding shares of Common Stock of the Company), or in case of
any conveyance or transfer of the properties and assets of the Company
substantially as an entirety, the corporation formed by such consolidation or
resulting from such merger or which acquires by conveyance or transfer such
properties and assets, as the case may be, shall execute and deliver to the
Trustee a supplemental indenture providing that the Holder of each Debenture
then outstanding shall have the right thereafter, during the period such
Debenture shall be convertible as specified in Section 12.01, to convert such
Debenture only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, conveyance or transfer by a holder
of the number of shares of Common Stock of the Company into which such Debenture
might have been converted immediately prior to such consolidation, merger,
conveyance or transfer, assuming such holder of Common Stock of the Company
failed to exercise his rights of election, if any, as to the kind or amount of
securities, cash and other property receivable upon such consolidation, merger,
conveyance or transfer (provided that, if the kind or amount of securities, cash
and other property receivable upon such consolidation, merger, conveyance or
transfer is not the same for each share of Common Stock of the Company in
respect of which such rights of election shall not have been exercised
("nonelecting share"), then for the purpose of this Section the kind and amount
of securities, cash and other property receivable upon such consolidation,
merger, conveyance or transfer by each nonelecting share shall be deemed to be
the kind and amount so receivable per share by a plurality of the nonelecting
shares).  Such supplemental indenture shall provide for adjustments which, for
events subsequent to the effective date of such supplemental indenture, shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article.  The above provisions of this Section shall similarly apply to
successive consolidations, mergers, conveyance or transfers.

          SECTION 12.11.  Responsibility of Trustee.  The Trustee, subject to
                          --------------------------                         
the provisions of Section 6.01, and any conversion agent shall not at any time
be under any duty or

                                                                              87

responsibility to any Holder to determine whether any facts exist which may
require any adjustment of the conversion price, or with respect to the nature or
extent of any such adjustment when made, or with respect to the method employed,
or herein or in any supplemental indenture, provided to be employed, in making
the same.  Neither the Trustee nor any conversion agent shall be accountable
with respect to the validity or value (or the kind or amount) of any shares of
Common Stock, or of any other securities or property, which may at any time be
issued or delivered upon the conversion of any Debenture; and it or they do not
make any representation with respect thereto.  Neither the Trustee nor any
conversion agent shall be responsible for any failure of the Company to make any
cash payment or to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property upon the surrender of any
Debenture for the purpose of conversion; and the Trustee, subject to the
provisions of Section 6.01, and any conversion agent shall not be responsible
for any failure of the Company to comply with any of the covenants of the
Company contained in this Article.

                          Subordination of Debentures
                          ---------------------------

          SECTION 13.01.  Debentures Subordinate to Senior Indebtedness.  The
                          ----------------------------------------------     
Company, for itself, its successors and assigns, covenants and agrees, and each
Holder of Debentures, by his acceptance thereof likewise covenants and agrees,
that all Debentures issued hereunder shall be subordinated and subject, to the
extent and in the manner herein set forth, in right of payment to the prior
payment in full of all Senior Indebtedness.

          SECTION 13.02.  No Payments when Senior Indebtedness in Default;
                          ------------------------------------------------
Payment Over of Proceeds upon Dissolution, etc.  In the event the Company shall
- -----------------------------------------------                                
default in the payment of any Senior Indebtedness when the same becomes due and
payable, whether at maturity or at a date fixed for prepayment or by declaration
or otherwise, then, unless and until such default shall have been cured or
waived or shall have ceased to exist, no direct or indirect payment (in cash,
property, securities, by setoff or otherwise) shall be made or agreed to be made
on account of the principal of (or premium, if any) or interest on the
Debentures, or in respect of any redemption, retirement, purchase or other
<PAGE>
 
                                                                              88

acquisition (except through the conversion thereof) of any of the Debentures.

          Upon the happening of an event of default with respect to any Senior
Indebtedness, as defined therein or in the instrument under which the same is
outstanding, permitting the holders thereof to accelerate the maturity thereof
(under circumstances when the terms of the preceding paragraph are not
applicable), unless and until such event of default shall have been cured or
waived or shall have ceased to exist, no direct or indirect payment (in cash,
property, securities, by setoff or otherwise) shall be made or agreed to be made
on account of the principal of (or premium, if any) or interest on the
Debentures, or in respect of any redemption, retirement, purchase or other
acquisition (except through the conversion thereof) of any of the Debentures.

          In the event of:

          (a) any insolvency, bankruptcy, receivership, liquidation,
     reorganization, readjustment, composition or other similar proceeding
     relating to the Company or its property;

          (b) any proceeding for the liquidation, dissolution or other winding
     up of the Company or its property;

          (c) any assignment by the Company for the benefit of creditors; or

          (d) any other marshalling of the assets of the Company;

all Senior Indebtedness (including any interest thereon accruing after the
commencement of any such proceedings) shall first be paid in full before any
payment or distribution (direct or indirect), whether in cash, property or
securities, by setoff or otherwise, shall be made to any Holder on account of
any Debentures, and to that end any payment or distribution, whether in cash,
property or securities (other than securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment the payment
of which is subordinate, at least to the extent provided in this Article with
respect to the Debentures, to the payment of all Senior Indebtedness at the time
outstanding and to any securities issued in respect
<PAGE>
 
                                                                              89

thereof under any such plan of reorganization or readjustment) which would
otherwise (but for the subordination provisions contained in this Article) be
payable or deliverable in respect of the Debentures shall be paid or delivered
directly to the holders of Senior Indebtedness, as their respective interests
may appear, until all Senior Indebtedness (including any interest thereon
accruing after the commencement of any such proceedings) shall have been paid in
full.

          If the Debentures are declared due and payable before their Stated
Maturity because of the occurrence of an Event of Default (under circumstances
where the preceding paragraph is not applicable), no payment (direct or
indirect) shall be made in respect of any Debenture unless and until all Senior
Indebtedness has been paid in full or such declaration and its consequence shall
have been rescinded and all such defaults shall have been remedied or waived.

          If any payment or distribution (other than securities of the Company
or any other corporation provided for by a plan of reorganization or
readjustment the payment of which is subordinate, at least to the extent
provided in this Article with respect to the Debentures, to the payment of all
Senior Indebtedness at the time outstanding and to any securities issued in
respect thereof under any such plan of reorganization or readjustment) shall be
received by the Trustee or the Holders in contravention of any of the terms of
this Article and before all the Senior Indebtedness has been paid in full, such
payment or distribution shall be held in trust for the benefit of, and shall be
paid over or delivered and transferred to, the holders of such Senior
Indebtedness at the time outstanding as their respective interests may appear
for application to the payment of Senior Indebtedness until all Senior
Indebtedness (including any interest thereon accruing after the commencement of
any such proceeding referred to in paragraph (a), (b), (c) or (d) above) shall
have been paid in full.  If the Trustee or any such Holder fails to endorse or
assign any such payment or distribution as required by this Section, the Trustee
and the Holder of each Debenture by his acceptance thereof authorizes each
holder of Senior Indebtedness, any representative or representatives of holders
of Senior Indebtedness and the trustee or trustees under any indenture pursuant
to which any instrument evidencing such Senior Indebtedness may have been issued
so to endorse or assign the same.

                                                                              90

          No holder of Senior Indebtedness shall be prejudiced in the right to
enforce subordination of the Debentures by any act or failure to act on the part
of the Company.

          Subject to the payment in full of all Senior Indebtedness, the Holders
shall be subrogated (equally and ratably with the holders of all indebtedness of
the Company which ranks on a parity with the Debentures and is entitled to like
rights of subrogation) to the rights of the holders of Senior Indebtedness to
receive payments or distributions applicable to the Senior Indebtedness until
the Debentures shall be paid in full, and no such payments or distributions
shall, as between the Company, its creditors other than the holders of Senior
Indebtedness and the Holders of the Debentures, be deemed to be a payment by the
Company to or on account of the Debentures.  The provisions of this Article are
and are intended solely for the purpose of defining the relative rights of the
Holders of the Debentures, on the one hand, and the holders of Senior
Indebtedness, on the other hand, and nothing contained in this Article or
elsewhere in this Indenture or in the Debentures is intended to or shall impair,
as between the Company, its creditors other than the holders of Senior
Indebtedness and the Holders of the Debentures, the obligation of the Company to
pay the Holders the principal of (and premium, if any) and interest on the
Debentures as and when the same shall become due and payable in accordance with
the terms thereof, or prevent the Trustee or the Holders from exercising all
rights, powers and remedies otherwise permitted by applicable law or under this
Indenture, upon a default or Event of Default hereunder, all subject to the
rights of the holders of Senior Indebtedness to receive cash, property or
securities otherwise payable or deliverable to the Trustee or the Holders.

          Upon any payment or distribution pursuant to this Section, the Trustee
shall be entitled to rely upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in this Section
are pending, and the Trustee, subject as between the Trustee and the Holders to
the provisions of Section 6.01, shall be entitled to rely upon a certificate of
the liquidating trustee or agent or other person making such payment or
distribution to the Trustee or to the Holders for the purpose of ascertaining
the Persons entitled to participate in such payment or distribution, the holders
of the Senior Indebtedness and other indebtedness of the
<PAGE>
 
                                                                              91

Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Section.
In the event that the Trustee determines, in good faith, that evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Section, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, as to the extent to which such Person is entitled to
participate in such payment or distribution, and as to other facts pertinent to
the rights of such Person under this Section, and if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

          SECTION 13.03.  Trustee To Effectuate Subordination.  The Holder of
                          ------------------------------------               
each Debenture by his acceptance thereof authorizes and directs the Trustee in
his behalf to take such action as may be necessary or appropriate to acknowledge
or effectuate the subordination as provided in this Article and appoints the
Trustee as attorney-in-fact for any and all such purposes.

          SECTION 13.04.  Trustee Not Charged with Knowledge of Prohibition.
                          -------------------------------------------------- 
Notwithstanding the provisions of this Article or any other provision of this
Indenture, but subject as between the Trustee and the Holders to the provisions
of Section 6.01, the Trustee shall not be charged with knowledge of the
existence of any Senior Indebtedness, or of any default in the payment of any
Senior Indebtedness, or of any facts which would prohibit the making of any
payment of moneys to or by the Trustee, unless and until three Business Days
after the Trustee shall have received written notice thereof from the Company or
any holder of Senior Indebtedness or the representative or representatives of
such holder, and the Trustee may conclusively rely on any writing purporting to
be from a holder of Senior Indebtedness, or a representative of such holder, as
being genuine; nor shall the Trustee be charged with knowledge of the curing of
any such default or of the elimination of the act or condition preventing any
such payment unless and until the Trustee shall have received an Officers'
Certificate to such effect.  The provisions of this Section shall not limit any
rights of holders of Senior Indebtedness under this Article XIII to recover from
the Holders of Debentures any payment made to any such Holder.

                                                                              92

          SECTION 13.05.  Rights of Trustee as Holder of Senior Indebtedness.
                          --------------------------------------------------- 
The Trustee shall be entitled to all the rights set forth in this Article with
respect to any Senior Indebtedness which may at any time be held by it, to the
same extent as any other holder of Senior Indebtedness; and nothing in Section
6.12, or elsewhere in this Indenture, shall deprive the Trustee of any of its
rights as such holder.

          SECTION 13.06.  Article Applicable to Paying Agent.  In case at any
                          -----------------------------------                
time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term "Trustee" as used in this Article
shall in such case (unless the context shall otherwise require) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that Sections 13.04
                                        --------  -------                     
and 13.05 shall not apply to the Company or any Affiliate of the Company if the
Company or such Affiliate acts as Paying Agent.


                                  ARTICLE XIV

                          Right To Require Repurchase
                          ---------------------------

          SECTION 14.01.  Right To Require Repurchase.  In the event that there
                          ----------------------------                         
shall occur a Change in Control (as defined in Section 14.05), each Holder shall
have the right, at such Holder's option to require the Company to purchase, and
upon the exercise of such right, the Company shall, subject to the provisions of
Article XIII, purchase, all or any part of such Holder's Debentures on the date
(the "Repurchase Date") that is 75 days after the date the Company gives notice
of the Change in Control as contemplated in Section 14.02(a) at a price (the
"Repurchase Price") equal to 100% of the principal amount thereof, together with
accrued and unpaid interest to the Repurchase Date.  In connection with the
exercise of the repurchase right by a Holder prior to a Redemption Date, a
Holder's right to exercise his repurchase right shall terminate at the close of
business on the Business Day prior to the Redemption Date.

          SECTION 14.02.  Notice; Method of Exercising Repurchase Right.  (a)
                          ----------------------------------------------      
On or before the 15th day after the Change in Control, the Company or, at the
request of the

                                                                              93

Company, the Trustee (in the name and at the expense of the Company), shall give
notice of the occurrence of the Change in Control and of the repurchase right
set forth herein arising as a result thereof by first-class mail, postage
prepaid, to each Holder of the Debentures at such Holder's address appearing in
the Debenture Register.  The Company shall also deliver a copy of such notice of
a repurchase right to the Trustee.

          Each notice of a repurchase right shall state:

          (i) the event constituting the Change in Control and the date thereof;

          (ii) the Repurchase Date;

          (iii) the date by which the repurchase right must be exercised;

          (iv) the Repurchase Price; and

          (v) the instructions a Holder must follow to exercise a repurchase
     right.

          No failure of the Company to give the foregoing notice shall limit any
Holder's right to exercise a repurchase right.  The Trustee shall have no
affirmative obligation to determine if there shall have occurred a Change in
Control.

          (b)  To exercise a repurchase right, a Holder shall deliver to the
Company (or an agent designated by the Company for such purpose in the notice
referred to in (a) above) and to the Trustee on or before the 10th day prior to
the Repurchase Date (i) written notice of the Holder's exercise of such right,

          stock that are, or immediately upon issuance will be, listed on a

          national securities exchange or quoted on The Nasdaq National Market,

          securities, shall be equal to the average of the daily Closing Prices
          of such securities during the 10 consecutive Trading Days commencing
          with the sixth Trading Day following consummation of such transaction)
          is at least 105% of the Conversion Price in effect on the date

                       STANDARD INDUSTRIAL LEASE -- NET

                  AMERICAN INDUSTRIAL REAL ESTATE ASSOCIATION

1.  Parties. This Lease, dated, for reference purposes only, September 1, 1993, 
is made by and between B & K Investment Company (herein called "Lessor") and 
Specialty Extrusions Limited (herein called "Lessee").

2.  Premises. Lessor hereby leases to Lessee and Lessee leases from Lessor for 
the term, at the rental, and upon all of the conditions set forth herein, that 
certain real property situated in the County of Orange State of California 
commonly known as 801 South Acacia Avenue (Portion of larger) and described as 
an approximately 15,000 square foot metal building and adjacent mobile office on
approximately one (1) acre of land as shown on Exhibit A attached hereto and 
made a part hereof. Said real property including the land and all improvements 
therein, is herein called "the Premises".

3.  Term.

    3.1  Term. The term of this Lease shall be for five (5) years commencing on 
September 1, 1993 and ending on August 31, 1998 unless sooner terminated 
pursuant to any provision hereof.

    3.2  Delay in Possession. Notwithstanding said commencement date, if for any
reason Lessor cannot deliver possession of the Premises to Lessee on said date, 
Lessor shall not be subject to any liability therefor, nor shall such failure 
affect the validity of this Lease or the obligations of Lessee hereunder or 
extend the term hereof, but in such case, Lessee shall not be obligated to pay 
rent until possession of the Premises is tendered to Lessee; provided, however, 
that if Lessor shall not have delivered possession of the Premises within sixty 
(60) days from said commencement date, Lessee may, at Lessee's option, by notice
in writing to Lessor within ten (10) days thereafter, cancel this Lease, in 
which event the parties shall be discharged from all obligations hereunder; 
provided further, however, that if such written notice of Lessee is not received
by Lessor within said ten (10) day period, Lessee's right to cancel this Lease 
hereunder shall terminate and be of no further force or effect.

    3.3  Early Possession. If Lessee occupies the Premises prior to said 
commencement date, such occupancy shall be subject to all provisions hereof, 
such occupancy shall not advance the termination date, and Lessee shall pay rent
for such period at the initial monthly rates set forth below.

4.  Rent.  Lessee shall pay to Lessor as rent for the Premises, monthly payments
of $7,717.00, in advance, on the first day of each month of the term hereof. 
Lessee shall pay Lessor upon the execution hereof $7,717.00 as rent for the 
month of September, 1993. Rent for any period during the term hereof which is 
for less than one month shall be a pro rata portion of the monthly installment. 
Rent shall be payable in lawful money of the United States to Lessor at the 
address stated herein or to such other persons or at such other places as Lessor
may designate in writing.

5.  Security Deposit. Lessee's $5,000.00 security deposit shall remain as 
security for Lessee's faithful performance of Lessee's obligations hereunder. If
Lessee fails to pay rent or other charges due hereunder, or otherwise defaults 
with respect to any provision of this Lease, Lessor may use, apply or retain all
or any portion of said deposit for the payment of any rent or other charge in 
default or for the payment of any other sum to which Lessor may become obligated
by reason of Lessee's default, or to compensate Lessor for any loss or damage 
which Lessor may suffer thereby. If Lessor so uses or applies all or any portion
of said deposit Lessee shall within ten (10) days after written demand therefor 
deposit cash with Lessor in an amount sufficient to restore said deposit to the 
full amount hereinabove stated and Lessee's failure to do so shall be a
<PAGE>
 
material breach of this Lease. If the monthly rent shall, from time to time,
increase during the term of this Lease, Lessee shall thereupon deposit with
Lessor additional security deposit so that the amount of security deposit held
by Lessor shall at all times bear the same proportion to current rent as the
original security deposit bears to the original monthly rent set forth in
paragraph 4 hereof. Lessor shall not be required to keep said deposit separate
from its general accounts. If Lessee performs all of Lessee's obligations
hereunder, said deposit, or so much thereof as has not theretofore been applied
by Lessor, shall be returned, without payment of interest or other increment for
its use, to Lessee (or, at Lessor's option, to the last assignee, if any, of
Lessee's interest hereunder) at the expiration of the term hereof, and after
Lessee has vacated the Premises. No trust relationship is created herein between
Lessor and Lessee with respect to said Security Deposit.

6.  Use. 

    6.1  Use. The Premises shall be used and occupied only for aluminum 
extrusion and related legal activities or any other use which is reasonably 
comparable and for no other purpose.

    6.2  Compliance with Law.

    (a) Lessor warrants to Lessee that the Premises, in its state existing on 
the date that the Lease term commences, but without regard to the use for which 
Lessee will use or has used the Premises, does not violate any covenants or 
restrictions of record, or any applicable building code, regulation or ordinance
in effect on such Lease term commencement date. In the event it is determined 
that this warranty has been violated, then it shall be the obligation of the 
Lessor, after written notice from Lessee, to promptly, at Lessor's sole cost and
expense, rectify any such violation. In the event Lessee does not give to Lessor
written notice of violation of this warranty within six months from the date
that the Lease term commences, the correction of same shall be the obligation of
the Lessee at Lessee's sole cost. The warranty contained in this paragraph 6.2
(a) shall be of no force or effect if, prior to the date of this Lease, Lessee
was the owner or occupant of the Premises, and, in such event, Lessee shall
correct any such violation at Lessee's sole cost.

    (b) Except as provided in paragraph 6.2(a), Lessee shall, at Lessee's 
expense, comply promptly with all applicable statutes, ordinances, rules, 
regulations, orders, covenants and restrictions of record, and requirements in 
effect during the term or any part of the term hereof, regulating the use by 
Lessee of the Premises. Lessee shall not use nor permit the use of the Premises 
in any manner that will tend to create waste or a nuisance or, if there shall be
more than one tenant in the building containing the Premises, shall tend to 
disturb such other tenants.

    6.3  Condition of Premises.

    (a)  Lessor shall deliver the Premises to Lessee clean and free of debris on
lease commencement date (unless Lessee is already in possession) and Lessor 
further warrants to Lessee that the plumbing, lighting, air conditioning, 
heating, and loading doors in the Premises shall be in good operating condition 
on the Lease commencement date. In the event that it is determined that this 
warranty has been violated, then it shall be the obligation of Lessor, after 
receipt of written notice from Lessee setting forth with specificity the nature 
of the violation, to promptly, at Lessor's sole cost, rectify such violation. 
Lessee's failure to give such written notice to Lessor within thirty (30) days 
after the Lease commencement date shall cause the conclusive presumption that 
Lessor has complied with all of Lessor's obligations hereunder. The warranty 
contained in this paragraph 6.3(a) shall be of no force or effect if prior to 
the date of this Lease, Lessee was the owner or occupant of the Premises.

    (b) Except as otherwise provided in this Lease, Lessee hereby accepts the 
Premises in their condition existing as of the Lease commencement date or the 
date that Lessee takes possession of the Premises, whichever is earlier, subject
to all applicable

                                       2
<PAGE>
 
zoning, municipal, county and state laws, ordinances and regulations governing 
and regulating the use of the Premises, and any covenants or restrictions of 
record and accepts this Lease subject thereto and to all matters disclosed 
thereby and by any exhibits attached hereto. Lessee acknowledges that neither 
Lessor nor Lessor's agent has made any representation or warranty as to the 
present or future suitability of the Premises for the conduct of Lessee's 
business.

    7.  Maintenance, Repairs and Alterations.

    7.1  Lessee's Obligations. Lessee shall keep in good order, condition and 
repair the Premises and every part thereof, structural and non structural, 
(whether or not such portion of the Premises requiring repair, or the means of 
repairing the same are reasonably or readily accessible to Lessee, and whether 
or not the need for such repairs occurs as a result of Lessee's use, any prior 
use, the elements or the age of such portion of the Premises) including, without
limiting the generality of the foregoing, all plumbing, heating, air 
conditioning, (Lessee shall procure and maintain, at Lessee's expense, an air 
conditioning system maintenance contract) ventilating, electrical, lighting 
facilities and equipment within the Premises, fixtures, walls (interior and 
exterior), foundations, ceilings, roofs (interior and exterior), floors, 
windows, doors, plate glass and skylights located within the Premises, and all 
landscaping, driveways, parking lots, fences and signs located on the Premises 
and sidewalks and parkways adjacent to the Premises.

    7.1.1  Toxic Waste Inspection. Lessee at Lessee's expense during the period 
between ninety (90) and forty-five (45) days prior to the expiration of the 
lease shall cause the premises to be inspected for toxic materials by a licensed
environmental inspection service approved in writing by Lessor and shall provide
Lessor with a written report issued by such a licensed environmental inspection 
service showing the results of the inspection and a determination of what 
corrective measures should be taken, if any, to eliminate such toxic materials, 
if any, to the extent necessary to meet the standards set out in the federal, 
state, county or municipal codes as to the presence of such materials. Lessee 
agrees that at its own expense, it will have such corrective measures performed 
and completed before the expiration of the lease.

    7.2  Surrender. On the last day of the term hereof, or on any sooner 
termination, Lessee shall surrender the Premises to Lessor in the same condition
as when received, ordinary wear and tear expected, clean and free of debris. 
Lessee shall repair any damage to the Premises occasioned by the installation or
removal of Lessee's trade fixtures, furnishings and equipment. Notwithstanding 
anything to the contrary otherwise stated in this Lease, Lessee shall leave the 
air lines, power panels, electrical distribution systems, lighting fixtures, 
space heaters, air conditioning, plumbing and fencing on the premises in good 
operating condition.

    7.3  Lessor's Rights. If Lease fails to perform Lessee's obligations under 
this Paragraph 7, or under any other paragraph of this Lease, Lessor may at its 
option (but shall not be required to) enter upon the Premises after ten (10) 
days' prior written notice to Lessee (except in the case of any emergency, in 
which case no notice shall be required), perform such obligations on Lessee's 
behalf and put the same in good order, condition and repair, and the cost 
thereof together with interest thereon at the maximum rate then allowable by law
shall become due and payable as additional rental to Lessor together with 
Lessee's next rental installment.

    7.4  Lessor's Obligations. Except for the obligations of Lessor under 
Paragraph 6.2(a) and 6.3(a) (relating to Lessor's warranty), Paragraph 9 
(relating to destruction of the Premises) and under Paragraph 14 (relating to 
condemnation of the Premises), it is intended by the parties hereto that Lessor 
have no obligations, in any manner whatsoever, to repair and maintain the 

                                       3
<PAGE>
 
Premises nor the building located thereon nor the equipment therein, whether 
structural or non structural, all of which obligations are intended to be that 
of the Lessee under Paragraph 7.1 hereof. Lessee expressly waives the benefit of
any statute now or hereinafter in effect which would otherwise afford Lessee the
right to make repairs at Lessor's expense or to terminate this Lease because of 
Lessor's failure to keep the premises in good order, condition and repair.

    7.5  Alterations and Additions.

    (a) Lessee shall not, without Lessor's prior written consent make any 
alterations, improvements, additions, or Utility Installations in, on or about 
the Premises, except for nonstructural alterations not exceeding $2,500 in 
cumulative costs during the term of this Lease. In any event, whether or not in 
excess of $2,500 in cumulative cost, Lessee shall make no change or alteration 
to the exterior of the Premises nor the exterior of the building(s) on the 
Premises without Lessor's prior written consent. As used in this Paragraph 7.5 
the term "Utility Installation" shall mean carpeting, window coverings, air 
lines, power panels, electrical distribution systems, lighting fixtures, space 
heaters, air conditioning, plumbing, and fencing. Lessor may require that Lessee
remove any or all of said alterations, improvements, additions or Utility 
Installations at the expiration of the term, and restore the Premises to their 
prior condition. Lessor may require Lessee to provide Lessor, at Lessee's sole 
cost and expense, a lien and completion bond in an amount equal to one and 
one-half times the estimated cost of such improvements, to insure Lessor against
any liability for mechanic's and materialmen's liens and to insure completion of
the work. Should Lessee make any alterations, improvements, additions or Utility
Installations without the prior approval of Lessor, Lessor may require that 
Lessee remove any or all of the same.

    (b) Any alterations, improvements, additions or Utility Installations in, or
about the Premises that Lessee shall desire to make and which requires the 
consent of the Lessor shall be presented to Lessor in written form, with 
proposed detailed plans. If Lessor shall give its consent, the consent shall be 
deemed conditioned upon Lessee acquiring a permit to do so from appropriate 
governmental agencies, the furnishing of a copy thereof to Lessor prior to the 
commencement of the work and the compliance by Lessee of all conditions of said 
permit in a prompt and expeditious manner.

    (c) Lessee shall pay, when due, all claims for labor or materials furnished 
or alleged to have been furnished to or for Lessee at or for use in the 
Premises, which claims are or may be secured by any mechanics' or materialmen's 
lien against the Premises or any interest therein. Lessee shall give Lessor not 
less than ten (10) days' notice prior to the commencement of any work in the 
Premises, and Lessor shall have the right to post notices of non-responsibility 
in or on the Premises as provided by law. If Lessee shall, in good faith, 
contest the validity of any such lien, claim or demand, then Lessee shall, at 
its sole expense defend itself and Lessor against the same and shall pay and 
satisfy any such adverse judgment that may be rendered thereon before the 
enforcement thereof against the Lessor or the Premises, upon the condition that 
if Lessor shall require, Lessee shall furnish to Lessor a surety bond 
satisfactory to Lessor in an amount equal to such contested lien claim or demand
indemnifying Lessor against liability for the same and holding the Premises free
from the effect of such lien or claim. In addition, Lessor may require Lessee to
pay Lessor's attorneys fees and costs in participating in such action if Lessor 
shall decide it is to its best interest to do so.

    (d) Unless Lessor requires their removal, as set forth in Paragraph 7.5(a), 
all alterations, improvements, additions and Utility Installations (whether or 
not such Utility Installations constitute trade fixtures of Lessee), which may 
be made on the Premises, shall become the property of Lessor and remain upon and
be surrendered with the Premises at the expiration of the term.

                                       4
<PAGE>
 
Notwithstanding the provisions of this Paragraph 7.5(d), Lessee's machinery and 
equipment, other than that which is affixed to the Premises so that it cannot be
removed without material damage to the Premises, shall remain the property of 
Lessee and may be removed by Lessee subject to the provisions of Paragraph 7.2.

8.  Insurance Indemnity.

    8.1  Insuring Party. As used in this Paragraph 8, the term "insuring party" 
shall mean the party who has the obligation to obtain the Property Insurance 
required hereunder. The insuring party shall be designated in Paragraph 46 
hereof. In the event Lessor is the insuring party, Lessor shall also maintain 
the liability insurance described in paragraph 8.2 hereof, in addition to, and 
not in lieu of, the insurance required to be maintained by Lessee under said 
paragraph 8.2, but Lessor shall not be required to name Lessee as an additional 
insured on such policy. Whether the insuring party is the Lessor or the Lessee, 
Lessee shall, as additional rent for the Premises, pay the cost of all insurance
required hereunder, except for that portion of the cost attributable to Lessor's
liability insurance coverage in excess of $1,000,000 per occurrence. If Lessor 
is the insuring party Lessee shall, within ten (10) days following demand by 
Lessor, reimburse Lessor for the cost of the insurance so obtained.

    8.2  Liability Insurance. Lessee shall, at Lessee's expense obtain and keep 
in force during the term of this Lease a policy of Combined Single Limit, Bodily
Injury and Property Damage insurance insuring Lessor and Lessee against any 
liability arising out of the ownership, use, occupancy or maintenance of the 
Premises and all areas appurtenant thereto. Such insurance shall be a combined 
single limit policy in an amount not less than $500,000 per occurrence. The 
policy shall insure performance by Lessee of the indemnity provisions of this 
Paragraph 8. The limits of said insurance shall not, however, limit the 
liability of Lessee hereunder.

    8.3  Property Insurance.

    (a) The insuring party shall obtain and keep in force during the term of 
this Lease a policy or policies of insurance covering loss or damage to the 
Premises, in the amount of the full replacement value thereof, as the same may 
exist from time to time, which replacement value is now $1,000,000.00, but in no
event less than the total amount required by lenders having liens on the 
Premises, against all perils included within the classification of fire, 
extended coverage, vandalism, malicious mischief, flood (in the event same is 
required by a lender having a lien on the Premises), and special extended perils
("all risk" as such term is used in the insurance industry). Said insurance 
shall provide for payment of loss thereunder to Lessor or to the holders of 
mortgages or deeds of trust on the Premises. The insuring party shall, in 
addition, obtain and keep in force during the term of this Lease a policy of 
rental value insurance covering a period of one year, with loss payable to 
Lessor, which insurance shall also cover all real estate taxes and insurance 
costs for said period. A stipulated value or agreed amount endorsement deleting 
the coinsurance provision of the policy shall be procured with said insurance as
well as an automatic increase in insurance endorsement causing the increase in 
annual property insurance coverage by 2% per quarter. If the insuring party 
shall fail to procure and maintain said insurance the other party may, but shall
not be required to, procure and maintain the same, but at the expense of Lessee.
If such insurance coverage has a deductible clause, the deductible amount shall 
not exceed $1,000 per occurrence, and Lessee shall be liable for such deductible
amount.

    (b) If the Premises are part of a larger building, or if the Premises are 
part of a group of buildings owned by Lessor which are adjacent to the Premises,
then Lessee shall pay for any increase in the property insurance of such other 
building or buildings if said increase is caused by Lessee's acts, omissions, 
use or occupancy of the Premises.

    (c) If the Lessor is the insuring party the Lessor will not

                                       5
<PAGE>
 
insure Lessee's fixtures, equipment or tenant improvements unless the tenant 
improvements have become a part of the Premises under paragraph 7, hereof. But 
if Lessee is the insuring party the Lessee shall insure its fixtures, equipment 
and tenant improvements.

    8.4  Insurance Policies. Insurance required hereunder shall be in companies 
holding a "General Policyholders Rating" of at least B plus, or such other 
rating as may be required by a lender having a lien on the Premises, as set 
forth in the most current issue of "Best's Insurance Guide". The insuring party 
shall deliver to the other party copies of policies of such insurance or 
certificates evidencing the existence and amounts of such insurance with loss 
payable clauses as required by this paragraph 8. No such policy shall be 
cancelable or subject to reduction of coverage or other modification except 
after thirty (30) days' prior written notice to Lessor. If Lessee is the 
insuring party Lessee shall, at least thirty (30) days prior to the expiration 
of such policies, furnish Lessor with renewals or "binders" thereof, or Lessor 
may order such insurance and charge the cost thereof to Lessee, which amount 
shall be payable by Lessee upon demand. Lessee shall not do or permit to be 
done anything which shall invalidate the insurance policies referred to in 
Paragraph 8.3. If Lessee does or permits to be done anything which shall 
increase the cost of the insurance policies referred to in Paragraph 8.3, then 
Lessee shall forthwith upon Lessor's demand reimburse Lessor for any additional 
premiums attributable to any act or omission or operation of Lessee causing such
increase in the cost of insurance. If Lessor is the insuring party, and if the 
insurance policies maintained hereunder cover other improvements in addition to 
the Premises, Lessor shall deliver to Lessee a written statement setting forth 
the amount of any such insurance cost increase and showing in reasonable detail 
the manner in which it has been computed.

    8.5  Waiver of Subrogation. Lessee and Lessor each hereby release and 
relieve the other, and waive the entire right of recovery against the other for 
loss or damage arising out of or incident to the perils insured against under 
paragraph 8.3, which perils occur in, on or about the Premises, whether due to 
the negligence of Lessor or Lessee or their agents, employees, contractors 
and/or invitees. Lessee and Lessor shall, upon obtaining the policies of 
insurance required hereunder, give notice to the insurance carrier or carriers 
that the foregoing mutual waiver of subrogation is contained in this Lease.

    8.6  Indemnity. Lessee shall indemnify and hold harmless Lessor from and 
against any and all claims arising from Lessee's use of the Premises, or from 
the conduct of Lessee's business or from any activity, work or things done, 
permitted or suffered by Lessee in or about the Premises or elsewhere and shall 
further indemnify and hold harmless Lessor from and against any and all claims 
arising from any breach or default in the performance of any obligation on 
Lessee's part to be performed under the terms of this Lease, or arising from any
negligence of the Lessee, or any of Lessee's agents, contractors, or employees, 
and from and against all costs, attorney's fees, expenses and liabilities 
incurred in the defense of any such claim or any action or proceeding brought 
thereon; and in case any action proceeding be brought against Lessor be reason 
of any such claim, Lessee upon notice from Lessor shall defend the same at 
Lessee's expense by counsel satisfactory to Lessor. Lessee, as a material part 
of the consideration to Lessor, hereby assume all risk of damage to property or 
injury to persons, in, upon or about the Premises arising from any cause and 
Lessee hereby waives all claims in respect thereof against Lessor.

    8.7  Exemption of Lessor from Liability. Lessee hereby agrees that Lessor 
shall not be liable for injury to Lessee's business or any loss of income 
therefrom or for damage to the goods, wares, merchandise or other property of 
Lessee, Lessee's employees, invitees, customers, or any other person in or about
the Premises, nor shall Lessor be liable for injury to the person of Lessee, 
Lessee's employees, agents or contractors, whether such

                                       6
<PAGE>
 
damage or injury is caused by or results from fire, steam, electricity, gas, 
water or rain, or from the breakage, leakage, obstruction or other defects of 
pipes, sprinklers, wires, appliances, plumbing, air conditioning or lighting 
fixtures, or from any other cause, whether the said damage or injury results 
from conditions arising upon the Premises or upon other portions of the building
of which the Premises are a part, or from other sources or places and regardless
of whether the cause of such damage or injury or the means of repairing the same
is inaccessible to Lessee. Lessor shall not be liable for any damages arising 
from any act or neglect of any other tenant, if any, of the building in which 
the Premises are located.

9.  Damage of Destruction.

    9.1  Definitions.

    (a) "Premises Partial Damage" shall herein mean damage or destruction to the
Premises to the extent that the cost of repair is less than 50% of the then 
replacement cost of the Premises. "Premises Building Partial Damage" shall 
herein mean damage or destruction to the building of which the Premises are a 
part to the extent that the cost of repair is less than 50% of the then 
replacement cost of such building as a whole.

    (b) "Premises Total Destruction" shall herein mean damage or destruction to 
the Premises to the extent that the cost of repair is 50% or more of the then 
replacement cost of the Premises. "Premises Building Total Destruction" shall 
herein mean damage or destruction to the building of which the Premises are a 
part to the extent that the cost of repair is 50% or more of the then 
replacement cost of such building as a whole.

    (c) "Insured Loss" shall herein mean damage or destruction which was caused 
by an event required to be covered by the insurance described in paragraph 8.

    9.2  Partial Damage -- Insured Loss. Subject to the provisions of paragraphs
9.4, 9.5, and 9.6, if at anytime during the term of this Lease there is damage 
which is an Insured Loss and which fails into the classification of Premises 
Partial Damage or Premises Building Partial Damage, then Lessor shall, at 
Lessor's expense, repair such damage, but not Lessee's fixtures, equipment or 
tenant improvements unless the same become a part of the Premises pursuant to 
Paragraph 7.5 hereof as soon as reasonably possible and this Lease shall 
continue in full force and effect. Notwithstanding the above, if the Lessee is 
the insuring party, and if the insurance proceeds received by Lessor are not 
sufficient to effect such repair, Lessor shall give notice to Lessee of the 
amount required in addition to the insurance proceeds to effect such repair. 
Lessee shall contribute the required amount to Lessor within ten days after 
Lessee has received notice from Lessor of the shortage in the insurance. When 
Lessee shall contribute such amount to Lessor, Lessor shall make such repairs as
soon as reasonably possible and this Lease shall continue in full force and 
effect. Lessee shall in no event have any right to reimbursement for any such 
amounts so contributed.

    9.3  Partial Damage -- Uninsured Loss. Subject to the provisions of 
Paragraphs 9.4, 9.5 and 9.6, at any time during the term of this Lease there is 
damage which is not an Insured Loss and which falls within the classification of
Premises Partial Damage or Premises Building Partial Damage, unless caused by a 
negligent or willful act of Lessee (in which event Lessee shall make the repairs
at Lessee's expense). Lessor may at Lessor's option either (i) repair such 
damage as soon as reasonably possible at Lessor's expense, in which event this 
Lease shall continue in full force and effect, or (ii) give written notice to 
Lessee within thirty (30) days after the date of the occurrence of such damage 
of Lessor's intention to cancel and terminate this Lessee, as of the date of the
occurrence of such damage. In the event Lessor elects to give such notice of 
Lessor's intention to cancel and terminate this Lease, Lessee shall have the 
right within ten (10) days after the receipt of such notice to give

                                       7
<PAGE>
 
written notice to Lessor of Lessee's intention to repair such damage at Lessee's
expense, without reimbursement from Lessor, in which event this Lease shall 
continue in full force and effect, and Lessee shall proceed to make such repairs
as soon as reasonably possible. If Lessee does not give such notice within such 
10-day period this Lease shall be canceled and terminated as of the date of the 
occurrence of such damage.

    9.4  Total Destruction. If at any time during the term of this Lease there 
is damage, whether or not an Insured Loss (including destruction required by 
any authorized public authority), which falls into the classification of 
Premises Total Destruction or Premises Building Total Destruction, this lease 
shall automatically terminate as of the date of such total destruction.

    9.5  Damage Near End of Term.

    (a) If at any time during the last six months of the term of this Lease 
there is damage, whether or not an Insured Loss, which falls within the 
classification of Premises Partial Damage, Lessor may at Lessor's option cancel 
and terminate this Lease as of the date of occurrence of such damage by giving 
written notice to Lessee of Lessor's election to do so within 30 days after the 
date of occurrence of such damage.

    (b) Notwithstanding paragraph 9.5(a), in the event that Lessee has an option
to extend or renew this Lease, and the time within which said option may be 
exercised has not yet expired, Lessee shall exercise such option, if it is to be
exercised at all, no later than 20 days after the occurrence of an Insured Loss 
falling within the classification of Premises Partial Damage during the last six
months of the term of this Lease. If Lessee duly exercises such option during 
said 20 day period, Lessor shall, at Lessor's expense, repair such damage as 
soon as reasonably possible and this Lease shall continue in full force and 
effect. If Lessee fails to exercise such option during said 20 day period, then 
Lessor may at Lessor's option terminate and cancel this Lease as of the 
expiration of said 20 day period by giving written notice to Lessee of Lessor's 
election to do so within 10 days after the expiration of said 20 day period, 
notwithstanding any term or provision in the grant of option to the contrary.

    9.6  Abatement of Rent; Lessee's Remedies.

    (a) In the event of damage described in paragraphs 9.2 or 9.3, through no 
fault of Lessee, and Lessor or Lessee repairs or restores the Premises pursuant 
to the provisions of this Paragraph 9, the rent payable hereunder for the period
during which such damage, repair or restoration continues shall be abated in 
proportion to the degree to which Lessee's use of the Premises is impaired. 
Except for abatement of rent, if any, Lessee shall have no claim against Lessor 
for any damage suffered by reason of any such damage, destruction, repair or 
restoration.

    (b) If Lessor shall be obligated to repair or restore the Premises under the
provisions of this Paragraph 9 and shall not commence such repair or restoration
within 90 days after such obligations shall accrue, Lessee may at Lessee's 
option cancel and terminate this Lease by giving Lessor written notice of 
Lessee's election to do so at any time prior to the commencement of such repair 
or restoration. In such event this Lease shall terminate as of the date of such 
notice.

    9.7  Termination -- Advance Payments. Upon termination of this Lease 
pursuant to this Paragraph 9, an equitable adjustment shall be made concerning 
advance rent and any advance payments made by Lessee to Lessor. Lessor shall, in
addition, return to Lessee so much of Lessee's security deposit as has not
theretofore been applied by Lessor.

    9.8  Waiver. Lessor and Lessee waive the provisions of any statutes which 
relate to termination of lease when leased property is destroyed and agree that 
such event shall be governed by the terms of this Lease.

10.  Real Property Taxes. 

    10.1  Payment of Taxes. Lessee shall pay the real property tax

                                       8
<PAGE>
 
as defined in paragraph 10.2, applicable to the Premises during the term of this
Lease. All such payments shall be made at least ten (10) days prior to the
delinquency date of such payment. Lessee shall promptly furnish Lessor with
satisfactory evidence that such taxes have been paid. If any such taxes paid by
Lessee shall cover any period of time prior to or after the expiration of the
term hereof, Lessee's share of such taxes shall be equitably prorated to cover
only the period of time within the tax fiscal year during which this Lease shall
be in effect and Lessor shall reimburse Lessee to the extent required. If Lessee
shall fail to pay any such taxes, Lessor shall have the right to pay the same,
in which case Lessee shall repay such amount to Lessor with Lessee's next rent
installment together with interest at the maximum rate then allowable by law.

    10.2  Definition of "Real Property Tax". As used herein, the term "real 
property tax" shall include any form of real estate tax or assessment, general, 
special, ordinary or extraordinary and any license fee, commercial rental tax, 
improvement bond or bonds, levy or tax (other than inheritance, personal income 
or estate taxes) imposed on the Premises by any authority having the direct or 
indirect power to tax, including any city, state or federal government, or any 
school, agricultural, sanitary, fire, street, drainage or other improvement 
district thereof, as against any legal or equitable interest of Lessor in the 
Premises or in the real property of which the Premises are a part, as against 
Lessor's right to rent or other income therefrom, and as against Lessor's 
business of leasing the Premises. The term "real property tax" shall also
include any tax, fee, levy, assessment or charge (i) in substitution of,
partially or totally, any tax, fee, levy, assessment or charge hereinabove
included within the definition of "real property tax," or (ii) the nature of
which was hereinbefore included within the definition of "real property tax," or
(iii) which is imposed for a service or right not charged prior to June 1, 1978,
or, if previously charged, has been increased since June 1, 1978, or (iv) which
is imposed as a result of a transfer, either partial or total, of Lessor's
interest in the Premises or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such transfer,
or (v) which is imposed by reason of this transaction, any modifications or
changes hereto, or any transfers hereof.

    10.3  Joint Assessment. If the Premises are not separately assessed, 
Lessee's liability shall be an equitable proportion of the real property taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be determined by Lessor from the respective valuations
assigned in the assessor's work sheets or such other information as may be
reasonably available. Lessor's reasonable determination thereof, in good faith,
shall be conclusive.

    10.4  Personal Property Taxes.

    (a) Lessee shall pay prior to delinquency all taxes assessed against and 
levied upon trade fixtures, furnishings, equipment and all other personal 
property of Lessee contained in the Premises or elsewhere. When possible, Lessee
shall cause said trade fixtures, furnishings, equipment and all other personal 
property to be assessed and billed separately from the real property of Lessor.

    (b) If any of Lessee's said personal property shall be assessed with 
Lessor's real property, Lessee shall pay Lessor the taxes attributable to Lessee
within 10 days after receipt of a written statement setting forth the taxes 
applicable to Lessee's property.

    11.  Utilities. Lessee shall pay for all water, gas, heat, light, power, 
telephone and other utilities and services supplied to the Premises, together 
with any taxes thereon. If any such services are not separately metered to 
Lessee, Lessee shall pay a reasonable proportion to be determined by Lessor of 
all charges jointly metered with other Premises.

    12.  Assignment and Subletting.

    12.1 Lessor's Consent Required. Lessee shall not voluntarily

                                       9

<PAGE>
 
or by operation of law assign, transfer, mortgage, sublet, or otherwise transfer
or encumber all or any part of Lessee's interest in this Lease or in the 
Premises, without Lessor's prior written consent, which Lessor shall not 
unreasonably withhold. Lessor shall respond to Lessee's request for consent 
hereunder in a timely manner and any attempted assignment, transfer, mortgage, 
encumbrance or subletting without such consent shall be void, and shall 
constitute a breach of this Lease.

    12.2  Lessee Affiliate. Notwithstanding the provisions of paragraph 12.1 
hereof, Lessee may assign or sublet the Premises, or any portion thereof, 
without Lessor's consent, to any corporation which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going concern of the business that is being
conducted on the Premises, provided that said assignee assumes, in full, the
obligations of Lessee under this Lease. Any such assignment shall not, in any
way, affect or limit the liability of Lessee under the terms of this Lease even
if after such assignment or subletting the terms of this Lease are materially
changed or altered without the consent of Lessee, the consent of whom shall not
be necessary.

    12.3  No Release of Lessee. Regardless of Lessor's consent, no subletting or
assignment shall release Lessee of Lessee's obligation or alter the primary 
liability of Lessee to pay the rent and to perform all other obligations to be 
performed by Lessee hereunder. The acceptance of rent by Lessor from any other 
person shall not be deemed to be a waiver by Lessor of any provision hereof. 
Consent to one assignment or subletting shall not be deemed consent to any 
subsequent assignment or subletting. In the event of default by any assignee of 
Lessee or any successor of Lessee, in the performance of any of the terms 
hereof, Lessor may proceed directly against Lessee without the necessity of 
exhausting remedies against said assignee. Lessor may consent to subsequent 
assignments or subletting of this Lease or amendments or modifications to this 
Lease with assignees of Lessee, without notifying Lessee, or any successor of 
Lessee, and without obtaining its or their consent thereto and such action shall
not relieve Lessee of liability under this Lease.

    12.4  Attorney's Fees. In the event Lessee shall assign or sublet the 
Premises or request the consent of Lessor to any assignment or subletting or if 
Lessee shall request the consent of Lessor for any act Lessee proposes to do 
then Lessee shall pay Lessor's reasonable attorneys fees incurred in connection 
therewith, such attorneys fees not to exceed $350.00 for each such request.

    13.  Defaults; Remedies.

    13.1  Defaults. The occurrence of any one or more of the following events 
shall constitute a material default and breach of this Lease by Lessee:

    (a) The vacating or abandonment of the Premises by Lessee.

    (b) The failure by Lessee to make any payment of rent or any other payment 
required to be made by Lessee hereunder, as and when due, where such failure 
shall continue for a period of three days after written notice thereof from 
Lessor to Lessee. In the event that Lessor serves Lessee with a Notice to Pay 
Rent or Quit pursuant to applicable Unlawful Detainer statutes such Notice to 
Pay Rent or Quit shall also constitute the notice required by this subparagraph.

    (c) The failure by Lessee to observe or perform any of the covenants, 
conditions or provisions of this Lease to be observed or performed by Lessee, 
other than described in paragraph (b) above, where such failure shall continue 
for a period of 30 days after written notice hereof from Lessor to Lessee; 
provided, however, that if the nature of Lessee's default is such that more than
30 days are reasonably required for its cure, then Lessee shall not be deemed to
be in default if Lessee commenced such cure within said 30-day period and
thereafter diligently prosecutes

                                      10

<PAGE>
 
such cure to completion.

    (d) (i) The making by Lessee of any general arrangement or assignment for 
the benefit of creditors; (ii) Lessee becomes a "debtor" as defined in 11 U.S.C.
(S)101 or any successor statute thereto (unless, in the case of a petition filed
against Lessee, the same is dismissed within 60 days); (iii) the appointment of 
a trustee or receiver to take possession of substantially all of Lessee's 
asset's located at the Premises or of Lessee's interest in this Lease, where 
possession is not restored to Lessee within 30 days; or (iv) the attachment, 
execution or other judicial seizure of substantially all of Lessee's assets 
located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within 30 days. Provided, however, in the event that
any provision of this paragraph 13.1(d) is contrary to any applicable law, such
provision shall be of no force or effect.

    (e) The discovery by Lessor that any financial statement given to Lessor by 
lessee, any assignee of Lessee, any subtenant of Lessee, any successor in 
interest of Lessee or any guarantor of Lessee's obligation hereunder, and any of
them, was materially false.

    13.2  Remedies. In the event of any such material default or breach by 
Lessee, Lessor may at any time thereafter, with or without notice or demand and 
without limiting Lessor in the exercise of any right or remedy which Lessor may 
have by reason of such default or breach:

    (a) Terminate Lessee's right to possession of the Premises by any lawful 
means, in which case this Lease shall terminate and Lessee shall immediately 
surrender possession of the Premises to Lessor. In such event Lessor shall be 
entitled to recover from Lessee all damages incurred by Lessor by reason of 
Lessee's default including, but not limited to, the cost of recovering 
possession of the Premises; expenses of reletting, including time of award by 
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such 
rental loss for the same period that Lessee proves could be reasonably avoided; 
that portion of the leasing commission paid by Lessor pursuant to Paragraph 15 
applicable to the unexpired term of this Lease.

    (b) Maintain Lessee's right to possession in which case this Lease shall 
continue in effect whether or not Lessee shall have abandoned the Premises. In 
such event Lessor shall be entitled to enforce all of Lessor's rights and 
remedies under this Lease, including the right to recover the rent as it becomes
due hereunder.

    (c) Pursue any other remedy now or hereafter available to Lessor under the 
laws or judicial decisions of the state wherein the Premises are located. Unpaid
installments of rent and other unpaid monetary obligations of Lessee under the 
terms of this Lease shall bear interest from the date due at the maximum rate 
then allowable by law.

    13.3  Default by Lessor. Lessor shall not be in default unless Lessor fails 
to perform obligations required of Lessor within a reasonable time, but in no 
event later than thirty (30) days after written notice by Lessee to Lessor and 
to the holder of any first mortgage or deed of trust covering the Premises whose
name and address shall have theretofore been furnished to Lessee in writing, 
specifying wherein Lessor has failed to perform such obligation; provided, 
however, that if the nature of Lessor's obligation is such that more than thirty
(30) days are required for performance then Lessor shall not be in default if 
Lessor commences performance within such 30-day period and thereafter diligently
prosecutes the same to completion.

    13.4  Late Charges. Lessee hereby acknowledges that late payment by Lessee 
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs 
not contemplated by this Lease, the exact amount of which will be extremely 
difficult to ascertain. Such costs include, but are not limited to, processing 
and accounting charges, and late charges which may be imposed on Lessor by the 
terms of any mortgage or trust deed covering the

                                      11

<PAGE>
 
Premises. Accordingly, if any installment of rent or any other sum due from 
Lessee shall not be received by Lessor or Lessor's designee within ten 
(10) days after such amount shall be due, then, without any requirement for
notice to Lessee, Lessee shall pay to Lessor a late charge equal to 6% of such
overdue amount. The parties hereby agree that such late charge represents a fair
and reasonable estimate of the costs Lessor will incur by reason of late payment
by Lessee. Acceptance of such late charge by Lessor shall in no event constitute
a waiver of Lessee's default with respect to such overdue amount, nor prevent
Lessor from exercising any of the other rights and remedies granted hereunder.
In the event that a late charge is payable hereunder, whether or not collected,
for three (3) consecutive installments of rent, then rent shall automatically
become due and payable quarterly in advance, rather than monthly,
notwithstanding paragraph 4 or any other provision of this Lease to the
contrary.

    13.5  Impounds. In the event that a late charge is payable hereunder, 
whether or not collected, for three (3) installments of rent or any other 
monetary obligation of Lessee under the terms of this Lease, Lessee shall pay to
Lessor, if Lessor shall so request, in addition to any other payments required
under this Lease, a monthly advance installment, payable at the same time as the
monthly rent, as estimated by Lessor, for real property tax and insurance
expenses on the Premises which are payable by Lessee under the terms of this
Lease. Such fund shall be established to insure payment when due, before
delinquency, of any or all such real property taxes and insurance premiums. If
the amounts paid to Lessor by Lessee under the provisions of this paragraph are
insufficient to discharge the obligation of Lessee to pay such real property
taxes and insurance premiums as the same become due, Lessee shall pay to Lessor,
upon Lessor's demand, such additional sums necessary to pay such obligations.
All moneys paid to Lessor under this paragraph may be intermingled with other
moneys of Lessor and shall not bear interest. In an event of a default in the
obligations of Lessee to perform under this Lease, then any balance remaining
from funds paid to Lessor under the provisions of this paragraph may, at the
option of Lessor, be applied to the payment of any monetary default of Lessee in
lieu of being applied to the payment of real property tax and insurance
premiums.

    14.  Condemnation. If the Premises or any portion thereof are taken under 
the power of eminent domain, or sold under the threat of the exercise of said 
power (all of which are herein called "condemnation"), this Lease shall
terminate as to the part so taken as of the date the condemning authority takes
title or possession, whichever first occurs. If more than 10% of the floor area
of the building on the Premises, or more than 25% of the land area of the
Premises which is not occupied by any building, is taken by condemnation, Lessee
may, at Lessee's option, to be exercised in writing only within ten (10) days
after Lessor shall have given Lessee written notice of such taking (or in the
absence of such notice, within ten (10) days after the condemnating authority
shall have taken possession) terminate this Lease as of the date the condemning
authority takes such possession. If Lessee does not terminate this Lease in
accordance with the foregoing, this Lease shall remain in full force and effect
as to the portion of the Premises remaining, except that the rent shall be
reduced in the proportion that the floor area of the building taken bears to the
total floor area of the building situated on the Premises. No reduction of rent
shall occur if the only area taken is that which does not have a building
located thereon. Any award for the taking of all or any part of the Premises
under the power of eminent domain or any payment made under threat of the
exercise of such power shall be the property of Lessor, whether such award shall
be made as compensation for diminution in value of the leasehold or for the
taking of the fee, or as severance damages; provided, however, that Lessee shall
be entitled to any award for loss of or damage to Lessee's trade fixtures and
removable personal property. In the event that this Lease is not terminated

                                      12

<PAGE>
 
by reason of such condemnation, Lessor shall to the extent of severance damages 
received by Lessor in connection with such condemnation, repair any damage to 
the Premises caused by such condemnation except to the extent that Lessee has 
been reimbursed therefor by the condemning authority. Lessee shall pay any 
amount in excess of such severance damages required to complete such repair.

15.  Broker's Fee.

    (a) Upon execution of this Lease by both parties, Lessor shall pay to Lee 
and Associates Commercial Brokerage Company (John Sullivan) Licensed real estate
broker(s), a fee as set forth in a separate agreement between Lessor and said 
broker(s), or in the event there is no separate agreement between Lessor and 
said broker(s), the sum as agreed, for brokerage services rendered by said 
broker(s) to Lessor in this transaction.

    (b) Lessor further agrees that if Lessee exercises any Option as defined in 
paragraph 39.1 of this Lease, which is granted to Lessee under this Lease, or 
any subsequently granted option which is substantially similar to an option 
granted to Lessee under this Lease or if Lessee acquires any rights to the 
Premises or other premises described in this Lease which are substantially 
similar to what Lessee would have acquired had an Option herein granted to 
Lessee been exercised, or if Lessee remains in possession of the Premises after 
the expiration of the term of this Lease after having failed to exercise an 
Option, or if said broker(s) are the procuring cause of any other lease or sale 
entered into between the parties pertaining to the Premises and/or any adjacent 
property in which Lessor has an interest, then as to any of said transactions, 
Lessor shall pay said broker(s) a fee in accordance with the schedule of said 
broker(s) in effect at the time of execution of this Lease.

    (c) Lessor agrees to pay said fee not only on behalf of Lessor but also on 
behalf of any person, corporation, association, or other entity having an 
ownership interest in said real property or any part thereof, when such fee is 
due hereunder. Any transferee of Lessor's interest in this Lease, whether such 
transfer is by agreement or by operation of law, shall be deemed to have assumed
Lessor's obligation under this Paragraph 15. Said broker shall be a third party 
beneficiary of the provisions of this Paragraph 15.

16.  Estoppel Certificate.

    (a) Lessee shall at any time upon not less than ten (10) days prior written 
notice from Lessor execute, acknowledge and deliver to Lessor a statement in 
writing (i) certifying that this Lease is unmodified and in full force and 
effect (or, if modified, stating the nature of such modification and certifying 
that this Lease, so modified, is in full force and effect) and the date to which
the rent and other charges are paid in advance, if any, and (ii) acknowledging 
that there are not, to Lessee's knowledge, any uncured defaults on the part of 
Lessor hereunder, or specifying such defaults if any are claimed. Any such 
statement may be conclusively relied upon by any prospective purchaser or 
encumbrancer of the Premises.

    (b) At Lessor's option, Lessee's failure to deliver such statement within 
such time shall be a material breach of this lease or shall be conclusive upon 
Lessee (i) that this Lease is in full force and effect, without modification 
except as may be represented by Lessor, (ii) that there are no uncured defaults 
in Lessor's performance, and (iii) that not more than one month's rent has been 
paid in advance or such failure may be considered by Lessor as a default by 
Lessee under this Lease.

    (c) If Lessor desires to finance, refinance, or sell the Premises, or any 
part thereof, Lessee hereby agrees to deliver to any lender or purchaser 
designated by Lessor such financial statements of Lessee as may be reasonably 
required by such lender or purchaser. Such statements shall include the past 
three years' financial statements of Lessee. All such financial statements

                                      13

<PAGE>
 
shall be received by Lessor and such lender or purchaser in confidence and shall
be used only for the purposes herein set forth.

17.  Lessor's Liability. The term "Lessor" as used herein shall mean only the 
owner or owners at the time in question of the fee title or a lessee interest in
a ground lease of the Premises, and except as expressly provided in Paragraph 
15, in the event of any transfer of such title or interest, Lessor herein named 
(and in case of any subsequent transfers then the grantor) shall be relieved 
from and after the date of such transfer of all liability as respects Lessor's 
obligations thereafter to be performed, provided that any funds in the hands of 
Lessor or the then grantor at the time of such transfer, in which Lessee has an 
interest, shall be delivered to the grantee. The obligations contained in this 
Lease to be performed by Lessor shall, subject as aforesaid, be binding on 
Lessor's successors and assigns, only during their respective periods of 
ownership.

18.  Severability. The invalidity of any provision of this Lease as determined 
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19.  Interest on Past-due Obligations. Except as expressly herein provided, any 
amount due to Lessor not paid when due shall bear interest at the maximum rate 
then allowable by law from the date due. Payment of such interest shall not 
excuse or cure any default by Lessee under this Lease, provided, however, that 
interest shall not be payable on late charges incurred by Lessee nor on any 
amounts upon which late charges are paid by Lessee.

20.  Time of Essence. Time is of the essence.

21.  Additional Rent. Any monetary obligations of Lessee to Lessor under the 
terms of this Lease shall be deemed to be rent.

22.  Incorporation of Prior Agreements; Amendments. This Lease contains all 
agreements of the parties with respect to any matter mentioned herein. No prior 
agreement or understanding pertaining to any such matter shall be effective. 
This Lease may be modified in writing only, signed by the parties in interest at
the time of the modification. Except as otherwise stated in this Lease, Lessee 
hereby acknowledges that neither the real estate broker listed in Paragraph 15 
hereof or any cooperating broker on this transaction nor the Lessor or any 
employees or agents of any of said persons has made any oral or written 
warranties or representations to Lessee relative to the condition or use by 
Lessee of said Premises and Lessee acknowledges that Lessee assumes all 
responsibility regarding the Occupational Safety Health Act, the legal use and 
adaptability of the Premises and the compliance thereof with all applicable laws
and regulations in effect during the term of this Lease except as otherwise 
specifically stated in this Lease.

23.  Notices. Any notice required or permitted to be given hereunder shall be in
writing and may be given by personal delivery or by certified mail, and if given
personally or by mail, shall be deemed sufficiently given if addressed to Lessee
or to Lessor at the address noted below the signature of the respective parties,
as the case may be. Either party may by notice to the other specify a different
address for notice purposes except that upon Lessee's taking possession of the
Premises, the Premises shall constitute Lessee's address for notice purposes. A
copy of all notices required or permitted to be given to Lessor hereunder shall
be concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate by notice to Lessee.

24.  Waivers. No waiver by Lessor or any provison hereof shall be deemed a 
waiver of any other provision hereof or of any

                                      14

<PAGE>
 
subsequent breach by Lessee of the same or any other provision. Lessor's consent
to, or approval of, any act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to or approval of any subsequent act by Lessee.
The acceptance of rent hereunder by Lessor shall not be a waiver of any
preceding breach by Lessee of any provision hereof, other than the failure of
Lessee to pay the particular rent so accepted, regardless of Lessor's knowledge
of such preceding breach at the time of acceptance of such rent.

25.  Recording. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

26.  Holding Over. If Lessee, with Lessor's consent, remains in possession of
the Premises or any pad thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, but all options and rights of
first refusal, if any, granted under the terms of this Lease shall be deemed
terminated and be of no further effect during said month to month tenancy.

27.  Cumulative Remedies. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28.  Covenants and Conditions. Each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

29.  Binding Effect; Choice of Law. Subject to any provisions hereof restricting
assignment or subletting by Lessee and subject to the provisions of Paragraph
17, this Lease shall bind the parties, their personal representatives,
successors and assigns. This Lease shall be governed by the laws of the State
wherein the Premises are located.

30.  Subordination.

     (a) This Lease, at Lessor's option, shall be subordinate to any ground
lease, mortgage, deed of trust, or any other hypothecation or security now or
hereafter placed upon the real property of which the Premises are a part and to
any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgage, trustee or ground lessor shall elect to have this Lease prior to the
lien of its mortgage, deed of trust or ground lease, and shall give written
notice thereof to Lessee, this Lease shall be deemed prior to such mortgage,
deed of trust, or ground lease, whether this Lease is dated prior or subsequent
to the date of said mortgage, deed of trust or ground lease or the date of
recording thereof.

     (b) Lessee agrees to execute any documents required to effectuate an
attornment, a subordination or to make the Lease prior to the lien of any
mortgage, deed of trust or ground lease, as the case may be. Lessee's failure to
execute such documents within 10 days after written demand shall constitute a
material default by Lessee hereunder, or, at Lessor's option, Lessor shall
execute such documents on behalf of Lessee as Lessee's attorney-in-fact. Lessee
does hereby make, constitute and irrevocably appoint Lessor as Lessee's 
attorney-in-fact and in Lessee's name, place and stead, to execute such
documents in accordance with this paragraph 30(b).

                                      15
     
<PAGE>
 
31.  Attorney's Fees. If either party or the broker named herein brings an 
action to enforce the terms hereof or declare rights hereunder, the prevailing
party in any such action, on trial or appeal, shall be entitled to his
reasonable attorney's fees to be paid by the losing party as fixed by the court.
The provisions of this paragraph shall inure to the benefit of the broker named
herein who seeks to enforce a right hereunder.

32.  Lessor's Access. Lessor and Lessor's agents shall have the right to enter 
the Premises at reasonable times for the purpose of inspecting the same, showing
the same to prospective purchasers, lenders, or lessees, and making such 
alterations, repairs, improvements or additions to the Premises or to the 
building of which they are a part as Lessor may deem necessary or desirable. 
Lessor may at any time place on or about the Premises any ordinary "For Sale" 
signs and Lessor may at any time during the last 120 days of the term hereof 
place on or about the Premises any ordinary "For Lease" signs, all without 
rebate of rent or liability to Lessee.

33.  Auctions. Lessee shall not conduct, nor permit to be conducted, either 
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the 
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34.  Signs. Lessee shall not place any sign upon the Premises without Lessor's 
prior written consent except that Lessee shall have the right, without the prior
permission of Lessor, to place ordinary and usual for rent or sublet signs 
thereon.

35.  Merger. The voluntary or other surrender of this Lease by Lessee, or a 
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to Lessor
of any or all of such subtenancies.

36.  Consents. Except for paragraph 33 hereof, wherever in this Lease the 
consent of one party is required to an act of the other party such consent shall
not be unreasonably withheld.

37.  Guarantor. In the event that there is a guarantor of this Lease, said 
guarantor shall have the same obligations as Lessee under this Lease.

38.  Quiet Possession. Upon Lessee paying the rent for the Premises and 
observing and performing all of the covenants, conditions and provisions on 
Lessee's part to be observed and performed hereunder, Lessee shall have quiet 
possession of the Premises for the entire term hereof subject to all of the 
provisions of this Lease. The individuals executing this Lease on behalf of 
Lessor represent and warrant to Lessee that they are fully authorized and 
legally capable of executing this Lease on behalf of Lessor and that such 
execution is binding upon all parties holding an ownership interest in the 
Premises.

39.  Options.

    39.1  Definition. As used in this paragraph the word "Options" has the 
following meaning: (1) the right or option to extend the term of this Lease or 
to renew this Lease or to extend or renew any lease that Lessee has on other 
property of Lessor; (2) the option or right of first refusal to lease the 
Premises or the right of first offer to lease the Premises or the right of first
refusal to lease other property of Lessor or the right of first offer to lease 
other property of Lessor; (3) the right or option to purchase the Premises, or 
the right of first refusal to purchase the Premises, or the right of first offer
to purchase the

                                      16
<PAGE>
 
Premises or the right or option to purchase other property of Lessor, or the 
right of first refusal to purchase other property of Lessor or the right of 
first offer to purchase other property of Lessor.

    39.2  Options Personal. Each Option granted to Lessee in this Lease are 
personal to Lessee and may not be exercised or be assigned, voluntarily or 
involuntarily, by or to any person or entity other than Lessee, provided, 
however, the Option may be exercised by or assigned to any Lessee Affiliate as 
defined in paragraph 12.2 of this Lease. The Options herein granted to Lessee
are not assignable separate and apart from this Lease.

    39.3  Multiple Options. In the event that Lessee has any multiple options to
extend or renew this Lease a later option cannot be exercised unless the prior 
option to extend or renew his Lease has been so exercised.

    39.4  Effect of Default on Options.

    (a) Lessee shall have no right to exercise an Option, notwithstanding any 
provision in the grant of Option to the contrary, (i) during the time commencing
from the date Lessor gives to Lessee a notice of default pursuant to paragraph 
13.1(b) or 13.1(c) and continuing until the default alleged in said notice of 
default is cured or (ii) during the period of time commencing on the day after a
monetary obligation to Lessor is due from Lessee and unpaid (without any 
necessity for notice thereof to Lessee) continuing until the obligation is paid,
or (iii) at any time after an event of default described in paragraphs 13.1(a), 
13.1(d), or 13.1(e) (without any necessity of Lessor to give notice of such
default to Lessee), or (iv) in the event that Lessor has given to Lessee three
or more notices of default under paragraph 13.1(b), where a late charge has
become payable under paragraph 13.4 for each of such defaults, or paragraph
13.1(c), whether or not the defaults are cured, during the 12 month period prior
to the time that Lessee intends to exercise the subject Option.

    (b) The period of time within which an Option may be exercised shall not be 
extended or enlarged by reason of Lessee's inability to exercise an Option 
because of the provisions of paragraph 39.4(a).

    (c) All rights of Lessee under the provisions of an Option shall terminate 
and be of no further force or effect, notwithstanding Lessee's due and timely 
exercise of the Option, if, after such exercise and during the term of this 
Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee for a 
period of 30 days after such obligation becomes due (without any necessity of 
Lessor to give notice thereof to Lessee), or (ii) Lessee fails to commence to 
cure a default specified in paragraph 13.1(c) within 30 days after the date that
Lessor gives notice to Lessee of such default and/or Lessee fails thereafter to 
diligently prosecute said cure to completion, or (iii) Lessee commits a default 
described in paragraph 13.1(a), 13.1(d) or 13.1(e) (without any necessity of 
Lessor to give notice of such default to Lessee), or (iv) Lessor gives to Lessee
three or more notices of default under paragraph 13.1(b), where a late charge 
becomes payable under paragraph 13.4 for each such default, or paragraph 
13.1(c), whether or not the defaults are cured.

40.  Multiple Tenant building. In the event that the Premises are part of a 
larger building or group of buildings then Lessee agrees that it will abide by, 
keep and observe all reasonable rules and regulations which Lessor may make from
time to time for the management, safety, care and cleanliness of the building 
and grounds, the parking of vehicles and the preservation of good order therein 
as well as for the convenience of other occupants and tenants of the building. 
The violations of any such rules and regulations shall be deemed a material 
breach of this Lease by Lessee..

41. Security Measures. Lessee hereby acknowledges that the rental

                                      17
<PAGE>
 
payable to Lessor hereunder does not include the cost of guard service or other 
security measures, and that Lessor shall have no obligation whatsoever to 
provide same. Lessee assumes all responsibility for the protection of Lessee, 
its agents and invitees from acts of third parties.

42.  Easements. Lessor reserves to itself the right, from time to time, to grant
such easements, rights and dedications that Lessor deems necessary or desirable,
and to cause the recordation of Parcel Maps and restrictions, so long as such 
easements, rights, dedications, Maps and restrictions do not unreasonably 
interfere with the use of the Premises by Lessee. Lessee shall sign any of the 
aforementioned documents upon request of Lessor and failure to do so shall 
constitute a material breach of this Lease.

43.  Performance Under Protest. If at any time a dispute shall arise as to any 
amount or sum of money to be paid by one party to the other under the provisions
hereof, the party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment, and there shall survive the right on the part
of said party to institute suit for recovery of such sum. If it shall be
adjudged that there was no legal obligation on the part of said party to pay
such sum or any part thereof, said party shall be entitled to recover such sum
or so much thereof as it was not legally required to pay under the provisions of
this Lease.

44.  Authority. If Lessee is a corporation, trust, or general or limited 
partnership, each individual executing this Lease on behalf of such entity 
represents and warrants that he or she is duly authorized to execute and deliver
this Lease on behalf of said entity. If Lessee is a corporation, trust or 
partnership, Lessee shall, within thirty (30) days after execution of this 
Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

45.  Conflict. Any conflict between the printed provisions of this Lease and 
the typewritten or handwritten provisions shall be controlled by the typewritten
or handwritten provisions.

46.  Insuring Party. The insuring party under this lease shall be the Lessee.

47.  Addendum. Attached hereto is an addendum or addenda containing paragraphs
1, 2 and 3 which constitutes a part of this lease.

LESSOR AND LESSEE HAVE CAREFULLY READ AND REVIEWED THIS LEASE AND EACH TERM AND

                                   --------

    THIS IS A GUARANTY by each of the undersigned (hereinafter referred to as 
"Guarantor") to B & K Investment company (hereinafter referred to as "Lessor").

unconditionally guarantees to Lessor the full and prompt payment by Lessee of 
all sums to be paid, expended and disbursed by Lessee and the full and prompt 
performance of any of the other covenants and conditions of the Lease at the 
times and in the manner and mode as provided by the Lease.

    This Guaranty shall be an independent obligation of each Guarantor and is 
independent of the obligation and liability of each Guarantor.

independent of the obligation and liabilities of Lessee. A separate action or 
actions may be brought against Lessee and whether Lessee be joined in any such 
action or actions. Each Guarantor waives all statutes of limitations affecting
his obligations or liabilities hereunder or the enforcement thereof.

otherwise be entitled by law, including, but not limited to, notice of
acceptance hereof, protests, presentment, notice of protest, notice of the
incurring by Lessee of obligations or liabilities, defaults, notice of default,
or breach of non-payment.

    Each Guarantor agrees to pay reasonable attorneys' fees and costs incurred 
by Lessor in enforcing this Guaranty whether or not suit is brought.

    This Guaranty shall inure to the benefit of Lessor and shall be binding upon
each Guarantor and their respective heirs, administrators, executors, successors
and assigns.

Dated: March 11, 1994.

                            Dated September 1, 1993

                  By and Between B & K Investment Company and

                         Specialty Extrusions Limited


1   RENT ESCALATIONS

(a) At the commencement of the 7th month, 25th month and 43rd month respectively
of the Lease term, the monthly rent payable under paragraph 4 of the attached
Lease shall be adjusted by the increase, if any, from the date this lease
commenced, in the Consumer Price Index of the Bureau of Labor Statistics of the
U.S. Department of Labor for Urban Wage Earners and Clerical Workers, Los
Angeles-Long Beach-Anaheim, California (1967=100), "All Items", herein referred
to as "C.P.I."

(b) The monthly rent payable in accordance with paragraph (a) of the Addendum
shall be calculated as follows: the rent payable for the first month of the term
of this Lease, as set forth in paragraph 4 of the attached Lease, shall be
multiplied by a fraction, the numerator of which shall be C.P.I. of the month
immediately preceding the effective date of the subject rent escalation and the
denominator of which shall be the C.P.I. for the first month of the Lease term.
The sum so calculated shall constitute the new monthly rent hereunder, but, in
no event, shall such new monthly rent be less than the rent payable for the
month immediately preceding the date for rent adjustment. In no event shall this
increase amount to less than a 7-1/2 percent increase of the base amount, every
eighteen months.

(c) In the event the compilation and/or publication of the C.P.I. shall be
transferred to any other governmental department or bureau or agency or shall be
discontinued, then the index most nearly the same as the C.P.I. shall be used to
make such calculation. In the event that Lessor and Lessee cannot agree on such
alternative index, then the matter shall be submitted for decision to the
American Arbitration Association in accordance with the then rules of said
association and the decision of the arbitrators shall be binding upon the
parties. The cost of said Arbitrators shall be paid equally by Lessor and
Lessee.

notification of the exercise of said option is not so given and
received, this option shall automatically expire;

     (ii) At the time said written notification of exercise of option is given
and received, Lessee shall not be in default under any of the material

have previously terminated nor terminated prior to the commencement of the
option term;

     (iii) All of the terms and conditions of this Lease except where
specifically modified by this option shall apply;

date of the business by giving notice of the intention to terminate within
thirty days of the transfer date. This option to terminate the lease on the sale
of the business shall apply to Lessee's purchaser only and not to any subsequent
