        have been made which are considered necessary to present fairly the
        financial position and the results of operations and cash flows at the
        dates and for the periods presented.

(2)     THE MERGERS

        On August 17, 1998, the Company completed a series of transactions.
        These transactions included, among other things, the formation by
        Insilco Holding Co. ("Holdings" or the "Company") then a wholly owned
        subsidiary of Insilco Corporation ("Insilco") of a wholly owned
        subsidiary ("ReorgSub"), followed by the merger of ReorgSub with and
        into Insilco Corporation (the "Reorganization Merger"), pursuant to
        which each stockholder of Insilco had his or her shares of Insilco
        converted into the same number of shares of Holdings and the right to
        receive $0.01 per share in cash, and Holdings became the parent of
        Insilco.

        Promptly following the Reorganization Merger, a second merger took place
        pursuant to which Silkworm Acquisition Corporation ("Silkworm"), an
        affiliate DLJMB, merged with and into Holdings (the "Merger," and
        together with the Reorganization Merger, the "Mergers") and each share
        of Holdings Common Stock was converted into the right to receive $43.47
        in cash and 0.03378 of a share of Holdings Common Stock. Thus, as a
        result of the Mergers, each stockholder of Insilco, in respect of each
        of his or her shares, received $43.48 in cash and retained 0.03378 of a
        share of Holdings Common Stock.

        Following the Mergers, (i) Insilco's existing stockholders retained, in
        the aggregate, approximately 10.1% (9.4% on a fully diluted basis) of
        the outstanding shares of Holdings Common Stock; (ii) the DLJMB Funds
        held approximately 69.0% (69.8% on a fully diluted basis) of the
        outstanding shares of Holdings Common Stock; (iii) 399 Venture Partners
        Inc., an affiliate of Citibank, N.A. ("CVC"), purchased shares of
        Silkworm which in the Merger were converted into approximately 19.3%
        (17.8% on a fully diluted basis) of the outstanding shares of Holdings
        Common Stock; and (iv) management of the Company purchased approximately
        1.7% (1.5% on a fully diluted basis) of the outstanding shares of
        Holdings Common Stock.

        Immediately prior to the effectiveness of the Reorganization Merger,
        each outstanding option to acquire shares of the common stock of Insilco
        granted to employees and directors, whether or not vested (the
        "Options") was canceled and in lieu thereof, each holder of an Option
        received a cash payment in an amount equal to (x) the excess, if any, of
        $45.00 over the exercise price of the Option multiplied by (y) the
        number of shares subject to the Option, less applicable withholding
        taxes (the "Option Cash Payments"). Certain holders of such Options
        elected to utilize amounts otherwise receivable by them to purchase
        $1,009,000 in equity and $2,659,000 in equity units of Holdings.

        The total amount of cash required to consummate the foregoing
        transactions was approximately $204.4

        million. This amount was financed with (i) gross proceeds of
        approximately $70.2 million from the issuance by Silkworm of units
        (which were converted into units of Holdings (the "Holdings Units") in
        the Merger), each unit consisting of $1,000 principal amount at maturity
        of 14% Senior Discount notes due 2008 (the "Holdings Senior Discount
        Notes") and one warrant to purchase 0.325 of a share of Holdings Common
        Stock at an exercise price of $0.01 per share, (ii) the issuance by
        Silkworm to the DLJMB Funds, CVC and certain members of management of
        Insilco, for an aggregate consideration of approximately $56.1 million,
        of 1,245,138 shares of Silkworm common stock (which was converted into
        Holdings Common Stock in the Merger), (iii) the issuance by Holdings to
        the DLJMB Funds, for an aggregate consideration, of $35.0 million of
        1,400,000 shares of Holdings' 15% Senior Exchangeable Preferred Stock
        due 2012 of (the "PIK Preferred Stock") and the DLJMB Warrants to
        purchase 65,603 shares of Holdings Common Stock at an exercise price of
        $0.01 per share, and (iv) approximately $43.1 million of new borrowings
        under the Company's existing credit facility (the "Existing Credit
        Facility").

        In the third quarter and first nine months of 1998 the Company incurred
        $24,188,000 and $25,529,000, respectively, of costs related to the
        merger.

(3)     1997 TRANSACTIONS

        In 1997, the Company completed several material transactions affecting
        its ongoing operations and debt and capital structure (the "1997
        Transactions") as described more fully below:

         -   On July 3, 1997, the Company refinanced its existing debt under a
             new six year $200 million amended and restated Credit Agreement.

         -   In the third quarter of 1997, the Company purchased an aggregate of
             5,714,284 shares of its common stock in two transactions using the
             proceeds from the sale of its traditional office products business
             ( the "Rolodex Business") within the Office Products/Specialty
             Publishing Group of $112,610,000, net of transaction costs, and the
             proceeds received on the issuance of the $150 million aggregate
             principal amount of 10 1/4% Senior Subordinated Notes due 2007 (the
             "10 1/4% Notes").

         Insilco remains a separate reporting entity under the Securities
         Exchange Act of 1934 because the 10 1/4% Notes are registered debt
         securities under the Securities Act of 1933.

(4)     DISCONTINUED OPERATIONS

        On March 5, 1997, the Company completed the sale of its Office Products
        Business (consisting of the Rolodex Business, Rolodex Electronics and
        Curtis, each as defined below) within the Office Products/Specialty
        Publishing Group with the divestiture of the Rolodex Business for
        $112,610,000, net of transaction costs, resulting in a gain of
        $57,788,000, net of taxes of $37,213,000. The divestiture of the Rolodex
        Business was preceded in 1996 by the divestiture of the Rolodex
        electronics product line ("Rolodex Electronics") and the Company's
        computer accessories business, Curtis Manufacturing Co., Inc.
        ("Curtis"). The proceeds from these sales aggregated $21,818,000.

        On July 7, 1998, the Company amended its Form 10-K for the year ended
        December 31, 1997 and its

                    Total inventories                  $60,989
                                                       =======

(6)     RELATED PARTY TRANSACTIONS

        In connection with the mergers, the Company paid Donaldson, Lufkin &
        Jenrette Securities Corporation ("DLJSC") an advisory fee of $3,500,000.
        Donaldson, Lufkin & Jenrette Capital Funding received $1,750,000 of fees
        from Insilco to secure a backstop credit facility in the event that the
        Company's Existing Revolving Credit Facility required refinancing. DLJSC
        also received from the Company the gross spread of $2,456,000 related to
        the Holdings Senior Discount Notes and $1,100,000 of fees related to a
        bridge loan facility commitment. In addition, the Company reimbursed
        DLJSC $110,000 for expenses related to the merger.

(7)     COMPREHENSIVE INCOME

        On January 1, 1998, the Company adopted the Financial Accounting
        Standards Board ("FASB") Statement No. 130 ("SFAS 130"), "Reporting
        Comprehensive Income". SFAS 130 establishes standards for reporting and
        display of comprehensive income in the financial statements.
        Comprehensive income is the total of net income and most other non-owner
        changes in equity. This statement expands or modifies disclosures and
        has no impact on the Company's financial position, results of operations
        or cash flows. Comprehensive income (loss) for the third quarters of
        1998 and 1997 totaled ($17,336,000) and $3,403,000, respectively,
        including other comprehensive income consisting of foreign currency
        translation adjustments (losses) totaling ($114,000) and ($184,000),
        respectively. Comprehensive income (loss) for the first nine months of
        1998 and 1997 totaled ($10,032,000) and $75,279,000, respectively,
        including other comprehensive income consisting of foreign currency
        translation adjustment (losses) totaling ($24,000) and ($2,834,000),
        respectively.

(8)     EARNINGS PER SHARE

        In 1997, the Company adopted Financial Accounting Standards Board
        ("FASB") Statement No. 128 ("SFAS 128"), "Earnings per Share", which
        simplifies the computation of earnings per share ("EPS"). All prior
        period earnings per share amounts have been restated to conform with
        SFAS 128 requirements. Under SFAS 128, the Company computes two earnings
        per share amounts - basic EPS and diluted EPS. Basic EPS is calculated
        based on the weighted average number of shares of common stock
        outstanding for the period. Diluted EPS is based on the weighted average
        number of shares of common stock outstanding for the period, including
        potential common stock which reflect the dilutive

</TABLE>

(9)     CONTINGENCIES

        The Company is implicated in various claims and legal actions arising in
        the ordinary course of business. Those claims or liabilities will be
        addressed in the ordinary course of business and will be paid as
        expenses are incurred. In the opinion of management, the ultimate
        disposition of these matters will not have a material adverse effect on
        the Company's consolidated financial position, results of operations or
        liquidity.

(10)    ESTIMATES

        In conformity with generally accepted accounting principles, the
        preparation of our financial statements requires our management to make
        estimates and assumptions that affect the amounts reported in our
        financial statements and accompanying actual results may ultimately
        differ from those estimates.

(11)    CONTINGENCY GAIN

        On January 14, 1997, the Company's subsidiary, Taylor Publishing Company
        ("Taylor"), sued one of its principal competitors in the yearbook
        business, Jostens, Inc. ("Jostens"), in the U.S. District Court for the
        Eastern District of Texas, alleging violations of the federal antitrust
        laws as well as various claims arising under state law. On May 13, 1998,
        a verdict was rendered in favor of Taylor and on June 12, 1998, the
        judge presiding over the litigation in the U.S. District Court rendered
        a judgment in the amount of $25,225,000 plus interest at the rate of
        5.434 percent. Jostens has announced that it will seek to overturn the
        verdict in post trial motions or on appeal and accordingly the Company
        has not recorded the gain. There can be no assurance as to the actual
        amount, if any, that Taylor will recover from Jostens. In the third
        quarter and first nine months

                               September 30, 1998

        of 1998, the Company incurred legal fees in connection with the Jostens
        lawsuit of $132,000 and $900,000, respectively.

(12)    DIVIDEND RESTRICTIONS

        The Company is a holding company and its ability to make payments in
        respect of the Holding Company Senior Discount Notes is dependent upon
        the receipt of dividends or other distributions from its direct and
        indirect subsidiaries. Insilco and its subsidiaries are parties to the
        Existing Credit Facility and Insilco is party to the 10 1/4% Note
        Indenture, each of which imposes substantial restrictions on Insilco's
        ability to pay dividends or make other distributions to the Company. Any
        payment of dividends or other distributions will be subject to certain
        financial conditions set forth in such indenture and is subject to
        certain prohibitions contained in the Existing Credit Facility. Under
        the most restrictive covenants, $4.25 million was free of limitations on
        the payment of dividends or other distributions at September 30, 1998.

(13)    SUBSEQUENT EVENTS -THE REFINANCING

        As a result of the Merger, the Company was required to make an Offer to
        Purchase (as defined in the indenture relating to the 10 1/4% Notes (the
        "10 1/4% Note Indenture") for all of the outstanding 10 1/4% Notes at
        101% of their aggregate principal amount, plus accrued interest. The
        Offer to Purchase expires on November 16, 1998 and the Company intends
        to repurchase all 10 1/4% Notes validly tendered and not withdrawn as
        promptly as practicable following acceptance of the 10 1/4% Notes. There
        is an aggregate of $150 million principal amount of 10 1/4% Notes
        outstanding.

        On November 9, 1998, the Insilco completed the sale of $120 million of
        12% Senior Subordinated Notes due 2007 (the "New Notes") with warrants
        to purchase 62,400 shares of Holdings common stock at $45 per share. The
        net proceeds from the offer and sale of the New Notes was approximately
        $116.0 million after payment of $3.6 million in underwriting fees to
        DLJSC and other expenses. These proceeds will be used to fund the
        repurchase of the 10 1/4% Notes validly tendered at a purchase price of
        101% of principal amount plus accrued and unpaid interest.

        The Indenture relating to the New Notes (the "Indenture") provides for a
        mandatory special redemption at par plus accrued interest to the extent
        that less than $120 million of the 10 1/4% Notes are tendered in the
        Offer to Purchase. The Indenture also provides for an 1/8% increase in
        the interest rate on the New Notes if the holders of the 10 1/4% Notes
        do not consent to an amendment to the 10 1/4% Note Indenture to permit
        the Company provide subsidiary guarantees to holders of the New Notes.

        DLJ Capital Funding Inc. ("DLJ Capital Funding") has committed to lend
        up to $300 million to the Insilco (the "New Credit Facility"). The New
        Credit Facility will be used to refinance the Existing Credit Facility
        and to fund a portion of the repurchase of the 10 1/4% Notes. The New
        Credit Facility will include a term loan facility (the "Term Loan
        Facility") and a revolving credit facility which will provide for
        revolving loans and up to $50 million of letters of credit (the
        "Revolving Credit Facility"). The Term Loan Facility will have a
        maturity of seven years. The Revolving Credit Facility will terminate on
        July 8, 2003. DLJ Capital Funding's commitment, however, is subject to
        significant conditions. The New Credit Facility together with the sale
        of the New Notes will be referred to herein as "The Refinancing".

(14)    PRO FORMA RESULTS OF OPERATIONS

        The following financial information presents 1998 and 1997 pro forma
        consolidated net sales and results of operations as if the mergers
        including the merger refinancing (see Note 2) and the Refinancing (see
        Note 13) had occurred as of the beginning of each respective period. The
        1997 pro forma consolidated net sales and results of operations are
        presented as if the 1997 Transactions had occurred at the beginning of
        1997, exclusive of nonrecurring items directly attributable to the
        transaction. The pro forma results of operations are as follows (in
        thousands, except per share data):

                       INDEPENDENT AUDITORS' REVIEW REPORT




THE BOARD OF DIRECTORS AND SHAREHOLDERS
INSILCO HOLDING CO:

We have reviewed the condensed consolidated balance sheet of Insilco Holding Co.
and subsidiaries as of September 30, 1998, the related condensed consolidated
income statements for the three-month and nine-month periods ended September 30,
1998 and 1997, the condensed consolidated statement of stockholders' equity
(deficit) for the nine months ended September 30, 1998, and the condensed
consolidated statements of cash flows for the nine-month periods ended September
30, 1998 and 1997. These condensed consolidated financial statements are the
responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the condensed consolidated financial statements referred to above for
them to be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Insilco Corporation and
subsidiaries as of December 31, 1997, and the related consolidated statements of
operations, stockholders' equity (deficit) and cash flows for the year then
ended (not presented herein); and in our report dated January 30, 1998, except
as to Note 21, which is as of June 8, 1998, and Note 2, which is as of July 7,
1998, we expressed an unqualified opinion on those consolidated financial
statements. In our opinion, the information set forth in the accompanying
condensed consolidated balance sheet as of December 31, 1997, is fairly stated,
in all material respects, in relation to the consolidated balance sheet from
which it has been derived.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS

The Company is a diversified manufacturer of automotive, telecommunications and
electronics components and is a publisher of school yearbooks and other
specialty publishing products. The Company's Automotive Components Group
manufactures transmission components and other stamped automotive components and
subassemblies at the Steel Parts unit, heat exchangers and heat exchanger tubing
at the Thermal Components unit, and stainless steel tubing used predominantly in
non-automotive applications at the Romac Metals unit. The Technologies Group
manufactures wire and cable assemblies for the telecommunications industry, high
performance data-grade connectors, precision metal stampings and power
transformers through its Escod Industries, Stewart Connector Systems, Stewart
Stamping, and Signal Transformer operating units, respectively. The Specialty
Publishing Group, which consists of Taylor Publishing, produces student
yearbooks and other specialty publishing products. The Company completed the
divestiture of its Office Products business with the sale of the Rolodex
Business in the first quarter of 1997. The Office Products Business is being
accounted for as a discontinued operation and, accordingly, the consolidated
statements of operations and cash flows for the periods prior to the sale have
been reclassified.

Summarized sales and operating income (loss) by business segment for the nine
months and three months ended September 30, 1998 compared to the corresponding
periods in 1997 are set forth in the following table (in thousands) and
discussed below:

SALES. Total net sales from continuing operations of $135,065,000 for the third
quarter of 1998 were up 3% or $3,671,000 over the corresponding period in 1997,
due to increased sales of automotive tubing at the Automotive Components Group
and increased sales at Taylor Publishing, due to the timing of yearbook
shipments. These sales increases were partially offset by a decline in the
Technologies Group caused by the continued weakness in the electronics market.
In the first nine months of 1998, net sales from continuing operations of
$422,388,000 increased 4% or $14,779,000 from 1997 primarily due to increased
sales at the Automotive Components Group of automotive tubing and industrial and
off-road radiators, and, to a lesser degree, increased sales at Specialty
Publishing related to the timing of yearbook shipments, partially offset by a
decline at the Technologies Group.

The Automotive Components Group's sales increased 11% or $6,299,000 and 8% or
$13,798,000 in the third quarter and first nine months of 1998, respectively,
compared to the corresponding periods of 1997 due to increased automotive tubing
sales in both the quarter and year-to-date periods. In addition, sales for the
first nine months of 1998 improved over the prior year due to increased sales of
radiators to OEMs serving the off-road and industrial equipment markets. These
increases were partially offset by a significant decline in sales at the
Company's heat exchanger capital equipment manufacturing division, McKenica,
which continues to experience a substantial decline in order backlog. Sales of
transmission and other stamped automotive parts at Steel Parts and of stainless
steel tubing for non-automotive applications, were both up slightly in the third
quarter of 1998 and were relatively flat on a year-to-date basis.

The Technologies Group's sales decreased 9% or $4,363,000 in the third quarter
of 1998 compared to the corresponding period in 1997 due to declines at Escod
and Signal Transformer primarily due to the weakness in the electronics market
which has continued in the third quarter. These declines were partially offset
by increased sales of Stewart Connector's modular data interconnect products due
to increased demand from a major telecommunications customer. Sales in the
Technologies Group decreased 2% or $3,307,000 in the first nine months of 1998
compared to the corresponding period in 1997 due to the weak demand in the
electronics market in the second and third quarters of 1998. These sales
decreases were partially offset by increased sales from Stewart Stamping and
increased sales of Stewart Connector's modular data interconnect products.

Taylor Publishing's sales of $27,381,000 and $91,922,000 for the third quarter
and first nine months of 1998, respectively, increased 7% and 5% compared to the
corresponding periods in 1997 primarily due to timing of yearbook shipments.

OPERATING INCOME. In the third quarter of 1998, the Company had an operating
loss of $16,334,000 compared to operating income of $10,963,000 in the prior
year period primarily due to $24,188,000 of expenses related to the merger. In
addition, the Company incurred $1,258,000 of expenses related to management
severance, the consolidation of two facilities and a noncompete infringement
lawsuit filed by the Company. The Company also experienced an operating loss at
its McKenica business unit due to a lack of available order backlog, lower
operating margins at Signal and Escod due to the weakness in the electronics
market and lower margins at Stewart Connector due to a less favorable mix of
products and price degradation on certain mature connector products.

For the first nine months of 1998, operating income decreased to $7,631,000 from
$39,764,000 in 1997 primarily due to $25,529,000 of expenses related to the
merger, approximately $900,000 in legal expenses (compared to $200,000 in 1997)
associated with Taylor's antitrust lawsuit against Jostens for which Taylor
received a favorable judgement totaling $25,225,000 (see Note 11) and $2,152,000
of expenses related to management severance, the consolidation of two facilities
and a noncompete infringement lawsuit filed by the Company. In addition, the
Company incurred increased costs, primarily higher shipping costs, from
production delays during its peak yearbook production season at Taylor
Publishing and lower margins at Steel Parts primarily due to increased costs
incurred to improve future operational efficiency and for the reasons cited
above, an operating loss at its McKenica business unit and lower operating
margins at Signal and Stewart Connector.

The Automotive Components Group's operating income in the third quarter of 1998
compared to the

                                       15

<PAGE>   16



corresponding period of 1997 decreased to $4,338,000 from $4,611,000 primarily
due to an operating loss of $225,000 at its McKenica business unit which
represented a $628,000 decline from the third quarter of 1997 operating income.
This decline was partially offset by improved operating income results at the
Company's heat exchanger and automotive tubing business. For the first nine
months of 1998, the Automotive Components Group's operating income compared to
the corresponding period of 1997 decreased to $15,809,000 from $17,211,000 due
to an operating loss of $535,000 at its McKenica business unit which represented
a $2,259,000 decline from 1997 and increased costs at Steel Parts incurred to
improve future operational efficiency. These declines were partially offset by
improved operating results at the other operating units of the Thermal
Components Group.

The Technologies Group's operating income decreased to $3,593,000 in the third
quarter of 1998 from $5,955,000 in the same period of 1997 as the continued
weakness in the electronics market caused significant declines in operating
income at Signal Transformer and Escod. Operating income at Stewart Connector
decreased from the prior year period due to a less favorable sales mix of
products and price degradation on certain mature connector products. For the
first nine months of 1998, the Technologies Group's operating income, compared
to the corresponding period of 1997, decreased to $14,183,000 from $17,326,000.
Operating income was impacted by the decreased sales of power transformers, wire
and cable assemblies and competitive pricing pressures in the connector market.
Partially offsetting these declines, operating income improved over the prior
year at Stewart Stamping.

Taylor Publishing had an operating loss of $59,000 in the third quarter of 1998
compared to operating income of $421,000 in 1997 primarily due to $300,000 of
severance expenses incurred in the third quarter of 1998 and $132,000 of legal
expenses associated with Taylor's antitrust lawsuit against Jostens. For the
first nine months of 1998, operating income decreased to $3,222,000 from
$5,535,000 in the prior year period primarily due to increased costs of labor
and air freight following production delays in the second quarter during its
peak yearbook production and delivery period. In addition, Taylor incurred
$900,000 of legal expenses associated with Taylor's antitrust lawsuit against
Jostens in the first nine months of 1998 compared to $200,000 in 1997.

OTHER INCOME (EXPENSE). Other income for the third quarters of 1998 and 1997
included $693,000 and $607,000, respectively, of equity income from the
Company's unconsolidated joint venture, Thermalex, which manufactures extruded
aluminum tubing primarily for automotive air conditioning condensers. For the
first nine months of 1998, other income included $2,144,000 of equity income
from Thermalex compared to $2,154,000 in 1997. Interest expense increased
$2,337,000 and $8,380,000 in the third quarter and first nine months of 1998,
respectively, from the corresponding 1997 periods due to the issuance of the
$150,000,000 of the 10 1/4% Notes completed in the third quarter of 1997 and the
issuance of the $70.2 million of 14% Senior Discount Notes in August 1998 (See
"The Merger Financing"). Interest income decreased $748,000 and $2,714,000 in
the third quarter and first nine months of 1998, respectively, from the
corresponding 1997 periods as a result of interest income earned on the proceeds
from the sale of the Rolodex Business in 1997.

"Other income, net", included in Other income (expense), for the third quarter
and first nine months of 1998 increased $285,000 and $2,242,000, respectively,
from the corresponding periods of 1997, respectively. Other income for the first
nine months of 1998 included gains on the sale of idle assets.

INCOME TAX EXPENSE. The Company incurred a net loss of $10,008,000 primarily due
to $25,529,000 of merger expenses incurred. Consequently, the tax benefit
arising from these losses was mitigated by the fact that a significant amount of
these costs were not deductible for tax, resulting in the 26% third quarter 1998
effective tax rate and a 5% effective tax rate for the nine month period ending
September 30, 1998.

CASH FLOWS FROM (USED IN) OPERATING ACTIVITIES. Operations used $26,244,000 of
cash in the first nine months of 1998 as compared to providing $11,621,000 in
the first nine months of 1997. Cash flows from operations in the first nine
months of 1998 were impacted by $25,529,000 of merger expenses incurred and
interest payments

                                       16

<PAGE>   17



related to the 10 1/4% Notes totaling $15,504,000 partially offset by Federal
income tax refund of $5,110,000. The Company's cash flow for periods prior to
the nine months ended September 30, 1997 was favorably impacted by tax loss
carryforwards, which reduced the actual cash payments for the years to well
below the financial statement income tax expense. The tax loss carryforwards
were substantially reduced in 1997 due to the gain from the sale of the Rolodex
Business.

CASH FLOWS FROM (USED IN) INVESTING ACTIVITIES. In March 1997, the Company sold
its Rolodex Business for a net sales price of $112,610,000. In the first nine
months of 1998 and 1997, the Company received dividend distributions from
Thermalex of $1,324,000 and $1,460,000, respectively. The Company's other
investing activities consisted principally of capital expenditures which totaled
$15,714,000 and $15,022,000 for the first nine months of 1998 and 1997,
respectively.

CASH FLOWS FROM (USED IN)FINANCING ACTIVITIES. Financing activities provided
$32,472,000 in the first nine months of 1998 compared to using $111,239,000 in
the first nine months of 1997. On August 17, 1998 a series of transactions
involving the Company were completed. (See "The Merger Financing" below.)

On July 3, 1997, the Company refinanced its bank debt (See Note 3 to the
condensed consolidated financial statements) and using the Rolodex Proceeds
purchased 2,857,142 shares of its common stock, at $38.50 per share in cash, for
an aggregate purchase price of $109,999,967. On August 12, 1997, the Company
completed the Tender Offer, in which it purchased an additional 2,857,142 shares
at a price of $38.50 per share in cash for an aggregate purchase price of
$109,999,967. On August 12, 1997, the Company issued $150 million of the 10 1/4%
Notes, for net proceeds of approximately $145.9 million (the "Offering"). The
Company used the net proceeds from the Offering to fund the repurchase of shares
tendered in the Tender Offer, repay loans under the Bank Credit Agreement, pay
fees and expenses of the aforementioned transactions and for general corporate
purposes. The Company incurred $11,126,000 in costs for the refinancing, Tender
Offer and issuance of the Notes.

SEASONALITY. The Company's yearbook publishing business, Taylor Publishing, is
highly seasonal, with a majority of its sales occurring in the second and third
quarters of the year. Taylor receives significant customer advance deposits in
the second half of the year. The Company's other businesses are not highly
seasonal.

IMPACT OF INFLATION AND CHANGING PRICES. Inflation and changing prices have not
significantly affected the Company's operating results or markets.

LIQUIDITY. At September 30, 1998, the Company's cash and cash equivalents and
net working capital amounted to $4,659,000 and $78,056,000, respectively,
representing a decrease in cash and cash equivalents of $5,992,000 and an
increase in net working capital of $38,548,000 from year end 1997. The borrowing
ability under the Insilco's revolving credit facility as of the end of the
quarter was $27,840,000 which is also available for issuing of letters of
credit.

Trade receivables, net, at September 30, 1998 increased 25% or $16,958,000 over
the December 31, 1997 amount primarily due to increased receivables at Taylor
Publishing following its peak yearbook production period (see Seasonality).

THE MERGER. On August 17, 1998, a series of transactions involving the Company
was completed. These transactions included, among other things, the formation by
Insilco Holding Co. ("Holdings" or the "Company") (then a wholly owned
subsidiary of Insilco) of a wholly owned subsidiary ("ReorgSub"), followed by
the merger of ReorgSub with and into Insilco (the "Reorganization Merger"),
pursuant to which each stockholder of Insilco had his or her shares of Insilco
converted into the same number of shares of Holdings and the right to receive
$0.01 per share in cash, and Holdings became the parent of the Company.

Promptly following the Reorganization Merger, a second merger took place
pursuant to which Silkworm

                                       17

<PAGE>   18



Acquisition Corporation ("Silkworm"), an affiliate DLJMB, merged with and into
Holdings (the "Merger," and together with the Reorganization Merger, the
"Mergers") and each share of Holdings Common Stock was converted into the right
to receive $43.47 in cash and 0.03378 of a share of Holdings Common Stock. Thus,
as a result of the Mergers, each stockholder of Insilco, in respect of each of
his or her shares, received $43.48 in cash and retained 0.03378 of a share of
Holdings Common Stock. Concurrently with the consummation of the Mergers, the
DLJMB Funds purchased 1,400,000 shares of Holdings 15% Senior Exchangeable
Preferred Stock due 2012 (the "PIK Preferred Stock"), and warrants to purchase
65,603 shares of Holdings Common Stock at an exercise price of $0.01 per share.

Following the Mergers, (i) Insilco's existing stockholders retained, in the
aggregate, approximately 10.1% (9.4% on a fully diluted basis) of the
outstanding shares of Holdings Common Stock; (ii) the DLJMB Funds held
approximately 69.0% (69.8% on a fully diluted basis) of the outstanding shares
of Holdings Common Stock; (iii) 399 Venture Partners Inc., an affiliate of
Citibank, N.A. ("CVC"), purchased shares of Silkworm which in the Merger were
converted into approximately 19.3% (17.8% on a fully diluted basis) of the
outstanding shares of Holdings Common Stock; and (iv) management of the Company
purchased approximately 1.7% (1.5% on a fully diluted basis) of the outstanding
shares of Holdings Common Stock.

Immediately prior to the effectiveness of the Reorganization Merger, each
outstanding option to acquire shares of the common stock of Insilco granted to
employees and directors, whether or not vested (the "Options") was canceled and
in lieu thereof, each holder of an Option received a cash payment in an amount
equal to (x) the excess, if any, of $45.00 over the exercise price of the Option
multiplied by (y) the number of shares subject to the Option, less applicable
withholding taxes (the "Option Cash Payments"). Certain holders of such Options
elected to utilize amounts otherwise receivable by them to purchase equity or
equity units of Holdings.

THE MERGER FINANCING. The total amount of cash required to consummate the
foregoing transactions was approximately $204.4 million. This amount was
financed with (i) gross proceeds of approximately $70.2 million from the
issuance by Silkworm of units (which were converted into units of Holdings (the
"Holdings Units") in the Merger), each unit consisting of $1,000 principal
amount at maturity of 14% Senior Discount notes due 2008 (the "Holdings Senior
Discount Notes") and one warrant to purchase 0.325 of a share of Holdings Common
Stock at an exercise price of $0.01 per share, (ii) the issuance by Holdings to
the DLJMB Funds, CVC and certain members of management of the Company, for an
aggregate consideration of approximately $56.1 million, of 1,245,138 shares of
Silkworm common stock (which was converted into Holdings Common Stock in the
Merger), (iii) the issuance to the DLJMB Funds for an aggregate consideration of
$35.0 million of 1,400,000 shares of the PIK Preferred Stock by Holdings and the
DLJMB Warrants to purchase 65,603 shares of Holdings Common Stock at an exercise
price of $0.01 per share, and (iv) approximately $43.1 million of new borrowings
under the Company's existing credit facility (the "Existing Credit Facility").

THE YEAR 2000 ISSUES. Many existing computer programs utilized globally use only
two digits to identify a year in the date field. These programs, if not
corrected, could fail or create erroneous results after the century date changes
on January 1, 2000 or when otherwise dealing with dates later than December 31,
1999. This " Year 2000" issue is believed to affect virtually all companies and
organizations, including the Company.

The Company relies on computer-based technology and primarily utilizes a variety
of third-party hardware and software and to a minimal degree some proprietary
software. In addition to such information technology ('IT") systems, the
Company's operations rely on various non-IT equipment and systems that contain
embedded computer technology. Third parties with whom the Company has commercial
relationships, including raw materials suppliers and service providers used by
the Company in its operations (such as banking and financial services, data
processing services, telecommunications services and utilities), are also highly
reliant on computer-based technology.

In 1996, the Company commenced an assessment of the potential effects of the
Year 2000 issue on the Company's

                                       18

<PAGE>   19



business, financial condition and results of operations. In conjunction with
such assessment, the Company developed and implemented a "Year 2000" compliance
program as described below.

THIRD-PARTY IT SYSTEMS. The majority of the Company's IT systems are third party
systems for which the Company has received Year 2000 compliant versions. The
Company does not expect any significant outlay of cash for these systems as all
of the third party systems are under current maintenance agreements which
provide for continuing operation including functions involving Year 2000. The
strategy instituted by the Company to identify and address Year 2000 issues
affecting third-party IT Systems includes contacting all third-party providers
of computer hardware and software to secure appropriate representations to the
effect that such hardware or software is or will timely be Year 2000 compliant.

PROPRIETARY IT SYSTEMS. The Company does not rely heavily on Company developed
proprietary IT systems. Pursuant to the Company's Year 2000 compliance program,
the Company has examined its proprietary IT systems for Year 2000 problems. All
such systems that were identified as relating to a critical function and were
not Year 2000 compliant are being fixed. The Company believes that nearly all of
the proprietary IT systems have been fixed and placed into production. The
Company is in the process of testing the remediated systems for Year 2000
compliance.

NON-IT SYSTEMS. The Company has undertaken a review of its non-IT systems and is
in the process of fixing such systems that are within the control of its
Company. The Company expects to complete this remediation effort by April 30,
1999.

NON-IT VENDORS AND SUPPLIERS. The Company procures its raw materials and
operating and supplies from a vast network of vendors located both within and
outside the United States. As a part of its contingency planning effort, the
Company is continually assessing the Year 2000 readiness of its important
vendors in order to identify any significant exposures that may exist and
establish alternate sources or strategies where necessary.

COSTS. Costs incurred to implement the Company's Year 2000 compliance program
have been immaterial to date and the Company presently expects to incur less
that $1.0 million of costs in the aggregate. All of the Company's Year 2000
compliance costs have been or are expected to be funded from the Company's
operating cash flow. The Company's Year 2000 compliance budget does not include
material amounts for hardware replacement because the Company has historically
employed a strategy to continually upgrade its business systems. Consequently,
the Company's Year 2000 budget has not required the diversion of funds from or
the postponement of the implementation of other planned IT projects.

RISKS ASSOCIATED WITH YEAR 2000 ISSUES. The Company's Year 2000 compliance
program is directed primarily towards ensuring that the Company will be able to
continue to perform three critical functions: (i) make and sell its products,
(ii) order and receive raw material and supplies, and (iii) pay its employees
and vendors. It is difficult, if not impossible, to assess with any degree of
accuracy the impact on any of these three areas of the failure of one or more
aspects of the Company's compliance program.

The novelty and complexity of the issues presented and the proposed solutions
therefore and the Company's dependence on the technical skills of employees and
independent contractors and on the representations and preparedness of third
parties are among the factors that could cause the Company's efforts to be less
than fully effective. Moreover, Year 2000 issues present a number of risks that
are beyond the Company's reasonable control, such as the failure of utility
companies to deliver electricity, the failure of telecommunications companies to
provide voice and data services, the failure of financial institutions to
process transactions and transfer funds, the failure of vendors to deliver
materials or perform services required by the Company and the collateral effects
on the Company of the effects of Year 2000 issues on the economy in general or
on the Company's customers in particular. Although the Company believes that its
Year 2000 compliance program is designed to appropriately identify and address
those Year 2000 issues that are subject to the Company's reasonable control,
there can be no

                                       19

<PAGE>   20



assurance that the Company's efforts in this regard will be fully effective or
that Year 2000 issues will not have a material adverse effect on the Company's
business, financial condition or results of operations.

SUBSEQUENT EVENTS. As a result of the Merger, the Company was required to make
an Offer to Purchase (as defined in the indenture (the "10 1/4% Note Indenture")
relating to the 10 1/4% Notes) for all of the outstanding 10 1/4% Notes at 101%
of their aggregate principal amount, plus accrued interest. The Offer to
Purchase expires on November 16, 1998 and the Company intends to repurchase all
10 1/4% Notes validly tendered and not withdrawn as promptly as practicable
following acceptance of the 10 1/4% Notes. There is an aggregate of $150 million
principal amount of 10 1/4% Notes outstanding.

On November 9, 1998 the Company completed the offering of $120 million of 12%
Senior Subordinated Notes (the "New Notes") due 2007 with warrants to purchase
62,400 shares of Holdings common stock. The net proceeds from the offer and sale
of the New Notes will be used to fund the repurchase of the 10 1/4% Notes
validly tendered at a purchase price of 101% of principal amount plus accrued
and unpaid interest.

DLJ Capital Funding Inc. ("DLJ Capital Funding") has committed to lend up to
$300 million to the Company (the "New Credit Facility"). The New Credit Facility
will be used to refinance the Existing Credit Facility and to fund any remaining
portion of the repurchase of 10 1/4% Notes. The New Credit Facility will include
a term loan facility (the "Term Loan Facility") and a revolving credit facility
(subject to adjustment), which will provide for revolving loans and up to $50
million of letters of credit (the "Revolving Credit Facility"). The Term Loan
Facility will have a maturity of seven years. The Revolving Credit Facility will
terminate on July 8, 2003. DLJ Capital Funding's commitment, however, is subject
to significant conditions.

Financial Condition and Results of Operations" include "Forward Looking
Statements" within the meaning of Section 27A of the Securities Act of 1933, as

in new product introductions, lack of market acceptance of new products, changes
in demand for the Company's products, changes in market trends, operating
hazards, general competitive pressures from existing and new competitors,
effects of governmental regulations, changes in interest rates, and adverse
economic conditions which could affect the amount of cash available for debt
servicing and capital investments. All subsequent written and oral
Forward-Looking Statements attributable to the Company or persons acting on its
behalf are expressly qualified in their entirety by the Cautionary Statements.

                  The Company hereby appoints the Warrant Agent to act as agent
for the Company in accordance with the instructions set forth hereinafter in
this Agreement and the Warrant Agent hereby accepts such appointment.

                  Section 3.   ISSUANCE OF WARRANTS; WARRANT CERTIFICATES.

                  3.1. FORM AND DATING.

                  (a) General.

                  The Warrants shall be substantially in the form of Exhibit A
hereto (the "WARRANT CERTIFICATES"). The Warrants may have notations, legends or
endorsements required by law, stock exchange rule or usage. Each Warrant shall
be dated the date of the countersignature. The terms and provisions contained in
the Warrants shall constitute, and are hereby expressly made, a part of this
Warrant Agreement. The Company and the Warrant Agent, by their execution and
delivery of this Warrant Agreement, expressly agree to such terms and provisions
and to be bound thereby. However, to the extent any provision of any Warrant
conflicts with the express provisions of this Warrant Agreement, the provisions
of this Warrant Agreement shall govern and be controlling.

                  (b) Global Warrants.

                  Warrants issued in global form shall be substantially in the
form of Exhibit A attached hereto (including the Global Warrant Legend thereon
and the "Schedule of Exchanges of Interests in the Global Warrant" attached
thereto). Warrants issued in definitive form ("DEFINITIVE WARRANTS") shall be
substantially in the form of Exhibit A attached hereto (but without the Global
Warrant Legend thereon and without the "Schedule of Exchanges of Interests in
the Global Warrant" attached thereto). Each Global Warrant shall represent such
of the outstanding Warrants as shall be specified therein and each shall provide
that it shall represent the number of outstanding Warrants from time to time
endorsed thereon and that the number of outstanding Warrants represented thereby
may from time to time be reduced or increased, as appropriate, to reflect
exchanges and redemptions. Any endorsement of a Global Warrant to reflect the
amount of any increase or decrease in the number of outstanding Warrants
represented thereby shall be made by the Warrant Agent in accordance with
instructions given by the Holder thereof as required by Section 3.5 hereof.

                  3.2. EXECUTION.

                  An Officer shall sign the Warrants for the Company by manual
or facsimile signature.

                  If the Officer whose signature is on a Warrant no longer holds
that office at the time a Warrant is countersigned, the Warrant shall
nevertheless be valid.

                  A Warrant shall not be valid until countersigned by the manual
signature of the Warrant Agent. The signature shall be conclusive evidence that
the Warrant has been properly issued under this Warrant Agreement.

                  The Warrant Agent shall, upon a written order of the Company
signed by an Officer (a "WARRANT COUNTERSIGNATURE ORDER"), countersign Warrants
for original issue up to the number stated in the preamble hereto.

                  The Warrant Agent may appoint an agent acceptable to the
Company to countersign Warrants. Such an agent may countersign Warrants whenever
the Warrant Agent may do so. Each reference in this Warrant Agreement to a
countersignature by the Warrant Agent includes a countersignature by such agent.
Such an agent has the same rights as the Warrant Agent to deal with the Company
or an Affiliate of the Company.

                  3.3.  REGISTRAR.

                  The Company shall maintain an office or agency where Warrants
may be presented for registration of transfer or for exchange ("WARRANT
REGISTRAR"). The Warrant Registrar shall keep a register of the Warrants and of
their transfer and exchange. The Company may appoint one or more co-Warrant
Registrars. The term "Warrant Registrar" includes any co-Warrant Registrar. The
Company may change any Warrant Registrar without notice to any holder. The
Company shall notify the Warrant Agent in writing of the name and address of any
agent not a party to this Warrant Agreement. If the Company fails to appoint or
maintain another entity as Warrant Registrar, the Warrant Agent shall act as
such. The Company or any of its subsidiaries may act as Warrant Registrar.

                  The Company initially appoints The Depository Trust Company
("DTC") to act as Depositary with respect to the Global Warrants.

                  The Company initially appoints the Warrant Agent to act as the
Warrant Registrar with respect to the Warrants.

                  3.4.  HOLDER LISTS.

                  The Warrant Agent shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of all Holders. If the Warrant Agent is not the Warrant Registrar, the
Company shall promptly furnish to the Warrant Agent at such times as the Warrant
Agent may request in writing, a list in such form and as of such date as the
Warrant Agent may reasonably require of the names and addresses of the Holders.

                  3.5.  TRANSFER AND EXCHANGE.

                                                                               7

                  (a)  Transfer and Exchange of Global Warrants.

                  A Global Warrant may not be transferred as a whole except by
the Depositary to a nominee of the Depositary, by a nominee of the Depositary to
the Depositary or to another nominee of the Depositary, or by the Depositary or
any such nominee to a successor Depositary or a nominee of such successor
Depositary. All Global Warrants will be exchanged by the Company for Definitive
Warrants if (i) the Company delivers to the Warrant Agent notice from the
Depositary that it is unwilling or unable to continue to act as Depositary or
that it is no longer a clearing agency registered under the Exchange Act and, in
either case, a successor Depositary is not appointed by the Company within 120
days after the date of such notice from the Depositary or (ii) the Company in
its sole discretion determines that the Global Warrants (in whole but not in
part) should be exchanged for Definitive Warrants and delivers a written notice
to such effect to the Warrant Agent. Upon the occurrence of either of the
preceding events in (i) or (ii) above, Definitive Warrants shall be issued in
such names as the Depositary shall instruct the Warrant Agent. Global Warrants
also may be exchanged or replaced, in whole or in part, as provided in Sections
3.6 and 3.7 hereof. A Global Warrant may not be exchanged for another Warrant
other than as provided in this Section 3.5(a) or pursuant to Section 3.5(c),
however, beneficial interests in a Global Warrant may be transferred and
exchanged as provided in Section 3.5(b) or (c) hereof.

                  (b) Transfer and Exchange of Beneficial Interests in the
Global Warrants.

                  The transfer and exchange of beneficial interests in the
Global Warrants shall be effected through the Depositary, in accordance with the
provisions of this Warrant Agreement and the Applicable Procedures. Beneficial
interests in the Restricted Global Warrants shall be subject to restrictions on
transfer comparable to those set forth herein to the extent required by the
Securities Act. Transfers of beneficial interests in the Global Warrants also
shall require compliance with either subparagraph (i) or (ii) below, as
applicable, as well as one or more of the other following subparagraphs, as
applicable:

                  (i) Transfer of Beneficial Interests in the Same Global
         Warrant. Beneficial interests in any Restricted Global Warrant may be
         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in the same Restricted Global Warrant in accordance
         with the transfer restrictions set forth in the Private Placement
         Legend. Beneficial interests in any Unrestricted Global Warrant may be
         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in an Unrestricted Global Warrant. No written
         orders or instructions shall be required to be delivered to the Warrant
         Registrar to effect the transfers described in this Section 3.5(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial Interests
         in Global Warrants. In connection with all transfers and exchanges of
         beneficial interests that are not subject to Section 3.5(b)(i) above,
         the transferor of such beneficial interest must deliver to the Warrant
         Registrar either (A) (1) a written order from a Participant or an
         Indirect

                                                                               8


         Participant given to the Depositary in accordance with the Applicable
         Procedures directing the Depositary to credit or cause to be credited a
         beneficial interest in another Global Warrant in an amount equal to the
         beneficial interest to be transferred or exchanged and (2) instructions
         given in accordance with the Applicable Procedures containing
         information regarding the Participant account to be credited with such
         increase or (B) (1) a written order from a Participant or an Indirect
         Participant given to the Depositary in accordance with the Applicable
         Procedures directing the Depositary to cause to be issued a Definitive
         Warrant in an amount equal to the beneficial interest to be transferred
         or exchanged and (2) instructions given by the Depositary to the
         Warrant Registrar containing information regarding the Person in whose
         name such Definitive Warrant shall be registered. Upon effectiveness of
         the Registration Statement (as defined in the Warrant Registration
         Rights Agreement) by the Company in accordance with Section 3.5(f)
         hereof, the requirements of this Section 3.5(b)(ii) shall be deemed to
         have been satisfied upon receipt by the Warrant Registrar of a
         certification required by the Company in connection with such
         Registration Statement delivered by the Holder of such beneficial
         interests in the Restricted Global Warrants. Upon satisfaction of all
         of the requirements for transfer or exchange of beneficial interests in
         Global Warrants contained in this Agreement and the Warrants or
         otherwise applicable under the Securities Act, the Warrant Agent shall
         adjust the principal amount of the relevant Global Warrant(s) pursuant
         to Section 3.5(h) hereof.

                  (iii)  (intentionally omitted)

                  (iv) Transfer and Exchange of Beneficial Interests in a
         Restricted Global Warrant for Beneficial Interests in the Unrestricted
         Global Warrant. A beneficial interest in any Restricted Global Warrant
         may be exchanged by any holder thereof for a beneficial interest in an
         Unrestricted Global Warrant or transferred to a Person who takes
         delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Warrant if the exchange or transfer complies with
         the requirements of Section 3.5(b)(ii) above and:

                           (A) such transfer is effected pursuant to the
                  Registration Statement in accordance with the Warrant
                  Registration Rights Agreement; or

                           (B) the Warrant Registrar receives the following:

                                    (1) if the holder of such beneficial
                           interest in a Restricted Global Warrant proposes to
                           exchange such beneficial interest for a beneficial
                           interest in an Unrestricted Global Warrant, a
                           certificate from such holder in the form of Exhibit C
                           hereto, including the certifications in item (1)(a)
                           thereof; or

                                    (2) if the holder of such beneficial
                           interest in a Restricted Global Warrant proposes to
                           transfer such beneficial interest to a Person

                                                                               9

                           who shall take delivery thereof in the form of a
                           beneficial interest in an Unrestricted Global
                           Warrant, a certificate from such holder in the form
                           of Exhibit B hereto, including the certifications in
                           item (3) thereof;

         and, in each such case (other than a transfer pursuant to Rule 144) set
         forth in this subparagraph (B), if the Warrant Registrar so requests or
         if the Applicable Procedures so require, an Opinion of Counsel in form
         reasonably acceptable to the Warrant Registrar to the effect that such
         exchange or transfer is in compliance with the Securities Act and that
         the restrictions on transfer contained herein and in the Private
         Placement Legend are no longer required in order to maintain compliance
         with the Securities Act.

                  If any such transfer is effected pursuant to subparagraph (B)
         above at a time when an Unrestricted Global Warrant has not yet been
         issued, the Company shall issue and, upon receipt of an Warrant
         Countersignature Order in accordance with Section 3.2 hereof, the
         Warrant Agent shall countersign one or more Unrestricted Global
         Warrants in the number equal to the number of beneficial interests
         transferred pursuant to subparagraph (B) above.

                  (c)  Transfer and Exchange of Beneficial Interests for 
         Definitive Warrants.

                  (i) Beneficial Interests in Restricted Global Warrants to
         Restricted Definitive Warrants. If any holder of a beneficial interest
         in a Restricted Global Warrant proposes to exchange such beneficial
         interest for a Restricted Definitive Warrant or to transfer such
         beneficial interest to a Person who takes delivery thereof in the form
         of a Restricted Definitive Warrant, then, upon receipt by the Warrant
         Registrar of the following documentation:

                           (A) if the holder of such beneficial interest in a
                  Restricted Global Warrant proposes to exchange such beneficial
                  interest for a Restricted Definitive Warrant, a certificate
                  from such holder in the form of Exhibit C hereto, including
                  the certifications in item (2)(a) thereof;

                           (B) if such beneficial interest is being transferred
                  to a QIB in accordance with Rule 144A under the Securities
                  Act, a certificate to the effect set forth in Exhibit B
                  hereto, including the certifications in item (1) thereof;

                           (C) if such beneficial interest is being transferred
                  to an Institutional Accredited Investor in reliance on an
                  exemption from the registration requirements of the Securities
                  Act other than those listed in subparagraph (B) above, a
                  certificate to the effect set forth in Exhibit B hereto,
                  including the certifications, certificates and Opinion of
                  Counsel required by item (2) thereof, if applicable; or

                           (D) if such beneficial interest is being transferred
                  to the Company or any of its Subsidiaries, a certificate to
                  the effect set forth in Exhibit B hereto, including the
                  certifications in item (2)(b) thereof,

         the Warrant Agent shall cause, in accordance with the standing
         instructions and procedures existing between the Depositary and the
         Warrant Agent, the number of Warrants represented by the Global Warrant
         to be reduced by the number of Warrants to be represented by the
         Definitive Warrant pursuant to Section 3.5(h) hereof, and the Company
         shall execute and the Warrant Agent shall countersign and deliver to
         the Person designated in the instructions a Definitive Warrant in the
         appropriate amount. Any Definitive Warrant issued in exchange for a
         beneficial interest in a Restricted Global Warrant pursuant to this
         Section 3.5(c) shall be registered in such name or names as the holder
         of such beneficial interest shall instruct the Warrant Registrar
         through instructions from the Depositary and the Participant or
         Indirect Participant. The Warrant Agent shall deliver such Definitive
         Warrants to the Persons in whose names such Warrants are so registered.
         Any Definitive Warrant issued in exchange for a beneficial interest in
         a Restricted Global Warrant pursuant to this Section 3.5(c)(i) shall
         bear the Private Placement Legend and shall be subject to all
         restrictions on transfer contained therein.

                  (ii) Beneficial Interests in Restricted Global Warrants to
         Unrestricted Definitive Warrants. A holder of a beneficial interest in
         a Restricted Global Warrant may exchange such beneficial interest for
         an Unrestricted Definitive Warrant or may transfer such beneficial
         interest to a Person who takes delivery thereof in the form of an
         Unrestricted Definitive Warrant only if:

                           (A) such transfer is effected pursuant to the
                  Registration Statement in accordance with the Warrant
                  Registration Rights Agreement; or

                                    (1) if the holder of such beneficial
                           interest in a Restricted Global Warrant proposes to
                           exchange such beneficial interest for a Definitive
                           Warrant that does not bear the Private Placement
                           Legend, a certificate from such holder in the form of
                           Exhibit C hereto, including the certifications in
                           item (1)(b) thereof; or

                                    (2) if the holder of such beneficial
                           interest in a Restricted Global Warrant proposes to
                           transfer such beneficial interest to a Person who
                           shall take delivery thereof in the form of a
                           Definitive Warrant that does not bear the Private
                           Placement Legend, a certificate from such holder in

                  and, in each such case (other than a transfer pursuant to Rule
                  144) set forth in this subparagraph (B), if the Warrant
                  Registrar so requests or if the Applicable Procedures so
                  require, an Opinion of Counsel in form reasonably acceptable
                  to the Warrant Registrar to the effect that such exchange or
                  transfer is in compliance with the Securities Act and that the
                  restrictions on transfer contained herein and in the Private
                  Placement Legend are no longer required in order to maintain
                  compliance with the Securities Act.

                  (iii) Beneficial Interests in Unrestricted Global Warrants to
         Unrestricted Definitive Warrants. If any holder of a beneficial
         interest in an Unrestricted Global Warrant proposes to exchange such
         beneficial interest for a Definitive Warrant or to transfer such
         beneficial interest to a Person who takes delivery thereof in the form
         of a Definitive Warrant, then, upon satisfaction of the conditions set
         forth in Section 3.5(b)(ii) hereof, the Warrant Agent shall cause the
         amount of the applicable Global Warrant to be reduced accordingly
         pursuant to Section 3.5(h) hereof, and the Company shall execute and
         the Warrant Agent shall countersign and deliver to the Person
         designated in the instructions a Definitive Warrant in the appropriate
         principal amount. Any Definitive Warrant issued in exchange for a
         beneficial interest pursuant to this Section 3.5(c)(iii) shall be
         registered in such name or names and in such authorized denomination or
         denominations as the holder of such beneficial interest shall instruct
         the Warrant Registrar through instructions from the Depositary and the
         Participant or Indirect Participant. The Warrant Agent shall deliver
         such Definitive Warrants to the Persons in whose names such Warrants
         are so registered. Any Definitive Warrant issued in exchange for a
         beneficial interest pursuant to this Section 3.5(c)(iii) shall not bear
         the Private Placement Legend.

                  (d) Transfer and Exchange of Definitive Warrants  for 
         Beneficial Interests.

                  (i) Restricted Definitive Warrants to Beneficial Interests in
         Restricted Global Warrants. If any Holder of a Restricted Definitive

of the Warrant Agent to reflect such reduction; and if the beneficial interest
is being exchanged for or transferred to a Person who will take delivery thereof
in the form of a beneficial interest in another Global Warrant, such other
Global Warrant shall be increased accordingly and an endorsement shall be made
on such Global Warrant by the Warrant Agent or by the Depositary at the
direction of the Warrant Agent to reflect such increase.

                  (i) General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the

         Warrant Registrar's request.

                  (ii) No service charge shall be made to a holder of a
         beneficial interest in a Global Warrant or to a holder of a Definitive
         Warrant for any registration of transfer or exchange, but the Company
         may require payment of a sum sufficient to cover any transfer tax or
         similar governmental charge payable in connection therewith .

                  (iii) All Global Warrants and Definitive Warrants issued upon
         any registration of transfer or exchange of Global Warrants or
         Definitive Warrants shall be the duly authorized, executed and issued
         warrants for Common Stock of the Company, not subject to any preemptive
         rights, and entitled to the same benefits under this Warrant Agreement,
         as the Global Warrants or Definitive Warrants surrendered upon such
         registration of transfer or exchange.

                  (iv) Prior to due presentment for the registration of a
         transfer of any Warrant, the Warrant Agent, and the Company may deem
         and treat the Person in whose name any

                                                                              19

         Warrant is registered as the absolute owner of such Warrant for all
         purposes and none of the Warrant Agent, or the Company shall be
         affected by notice to the contrary.

                  (v) The Warrant Agent shall countersign Global Warrants and
         Definitive Warrants in accordance with the provisions of Section 3.2
         hereof.

                  (j) Facsimile Submissions to Warrant Agent.

                  All certifications, certificates and Opinions of Counsel
required to be submitted to the Warrant Registrar pursuant to this Section 3.5
to effect a registration of transfer or exchange may be submitted by facsimile.
All references to Exhibits B and C herein shall include any other form of
certificate containing comparable certifications approved by the Company).

                  Notwithstanding anything herein to the contrary, as to any
certificates and/or certifications delivered to the Warrant Registrar pursuant
to this Section 3.5, the Warrant Registrar's duties shall be limited to
confirming that any such certifications and certificates delivered to it are
substantially in the form of Exhibits B and C attached hereto. The Warrant
Registrar shall not be responsible for confirming the truth or accuracy of
representations made in any such certifications or certificates. As to any
Opinions of Counsel delivered pursuant to this Section 3.5, the Warrant

                  3.6. REPLACEMENT WARRANTS.

                  If any mutilated Warrant is surrendered to the Warrant Agent
or the Company and the Warrant Agent receives evidence to its satisfaction of
the destruction, loss or theft of any Warrant, the Company shall issue and the
Warrant Agent, upon receipt of a Warrant Countersignature Order, shall
countersign a replacement Warrant if the Warrant Agent's requirements are met.
If required by the Warrant Agent or the Company, an indemnity bond must be
supplied by the Holder that is sufficient in the judgment of the Warrant Agent
and the Company to protect the Company, the Warrant Agent, any Agent and any
agent for purposes of the countersignature from any loss that any of them may
suffer if a Warrant is replaced. The Company may charge for its expenses in
replacing a Warrant.

                  Every replacement Warrant is an additional warrant of the
Company and shall be entitled to all of the benefits of this Warrant Agreement
equally and proportionately with all other Warrants duly issued hereunder.

                  3.7. TEMPORARY WARRANTS.

delivery, the Company may prepare and the Warrant Agent, upon receipt of a
Warrant Countersignature Order, shall issue

                                                                              20


temporary Warrants. Temporary Warrants shall be substantially in the form of
certificated Warrants but may have variations that the Company considers
appropriate for temporary Warrants and as shall be reasonably acceptable to the
Warrant Agent. Without unreasonable delay, the Company shall prepare and the
Warrant Agent shall countersign definitive Warrants in exchange for temporary
Warrants.

                  Holders of temporary Warrants shall be entitled to all of the
benefits of this Warrant Agreement.

                  3.8. CANCELLATION.

deliver Warrants to the Warrant Agent for cancellation. The Warrant Registrar
and Warrant Paying Agent shall forward to the Warrant Agent any Warrants
surrendered to them for registration of transfer, exchange or exercise. The
Warrant Agent and no one else shall cancel all Warrants surrendered for
registration of transfer, exchange, exercise, replacement or cancellation and
shall destroy canceled Warrants (subject to the record retention requirement of
the Exchange Act). Certification of the destruction of all canceled Warrants
shall be delivered to the Company. The Company may not issue new Warrants to
replace Warrants that have been exercised or that have been delivered to the
Warrant Agent for cancellation.

                  SECTION 4. SEPARATION OF WARRANTS; TERMS OF WARRANTS; 
                             ------------------------------------------
EXERCISE OF WARRANTS.
- - ---------------------

                  (a) The Notes and Warrants will not be separately transferable
until the Separation Date. Subject to the terms of this Agreement, each Warrant
holder shall have the right, which may be exercised during the period commencing
at the opening of business on the Separation Date and until 5:00 p.m., New York
City time on August 15, 2007 (the "EXERCISE PERIOD"), to receive from the
Company the number of fully paid and nonassessable Warrant Shares which the
holder may at the time be entitled to receive on exercise of such Warrants and
payment of the exercise price (the "EXERCISE PRICE") as set forth below in cash,
by wire transfer or by certified or official check payable to the order of the
Company, in each case, equal to the Exercise Price then in effect for such
Warrant Shares; provided that holders shall be able to exercise their Warrants
only if a registration statement relating to the such exercise is then in
effect, or the exercise of such Warrants is exempt from the registration
requirements of the Securities Act of 1933, as amended (the "Securities Act")
and such holder delivers to the Company such notices as the Company shall
reasonably request in connection therewith, and such securities are qualified
for sale or exempt from qualification under the applicable securities laws of
the states in which the various holders of the Warrants or other persons to whom
it is proposed that the Warrant Shares be issued on exercise of the Warrants
reside. Each holder may exercise its right, during the Exercise Period, to
receive Warrant Shares on a net basis, such that, without the exchange of any
funds, the holder will receive such number of Warrant Shares equal to the


<PAGE>   22
                                                                              21



product of (A) the number of Warrant Shares for which such Warrant is
exercisable as of the date of exercise (if the Exercise Price were being paid in
cash) and (B) the Cashless Exercise Ratio. The Cashless Exercise Ratio shall
equal a fraction the numerator of which is the Market Value (as defined below)
per share of Common Stock minus the Exercise Price per share as of the date of
exercise and the denominator of which is the Market Value per share on the date
of exercise. Each Warrant not exercised prior to 5:00 p.m., New York City time,
on August 15, 2007 (the "EXPIRATION DATE") shall become void and all rights
thereunder and all rights in respect thereof under this agreement shall cease as
of such time. No adjustments as to dividends will be made upon exercise of the
Warrants.

                  The "Market Value" per share of Common Stock as of any date
shall equal (i) if Common Stock is primarily traded on a securities exchange,
the last sale price on such securities exchange on the trading day immediately
prior to the date of determination, or if no sales occurred on such day, the
mean between the closing "bid" and "asked" prices on such day, (ii) if the
principal market for Common Stock is in the over-the-counter market, the closing
sale price on the trading day immediately prior to the date of the
determination, as published by the National Association of Securities Dealers
Automated Quotation System or similar organization, or if such price is not so
published on such day, the mean between the closing "bid" and "asked" prices, if
available, on such day, which prices may be obtained from any reputable pricing
service, broker or dealer, and (iii) if neither clause (i) nor clause (ii) is
applicable, the fair market value on the date of determination of Common Stock
as determined in good faith by the Board of Directors of the Company.

                  (b) In order to exercise all or any of the Warrants
represented by a Warrant Certificate, the holder thereof must deliver to the
Warrant Agent at its corporate trust office set forth in Section 15 hereof the
Warrant Certificate and the form of election to purchase on the reverse thereof
duly filled in and signed, which signature shall be medallion guaranteed by an
institution which is a member of a Securities Transfer Association recognized
signature guarantee program, and upon payment to the Warrant Agent for the
account of the Company of the Exercise Price, which is set forth in the form of
Warrant Certificate attached hereto as Exhibit A, as adjusted as herein
provided, for the number of Warrant Shares in respect of which such Warrants are
then exercised. Payment of the aggregate Exercise Price shall be made (i) in
cash, by wire transfer or by certified or official bank check payable to the
order of the Company or (ii) on a net basis in the manner provided in Section
4(a) hereof.

                  (c) Subject to the provisions of Section 5 hereof, upon
compliance with clause (b) above, the Warrant Agent shall deliver or cause to be
delivered with all reasonable dispatch, to or upon the written order of the
holder and in such name or names as the Warrant holder may designate, a
certificate or certificates for the number of whole Warrant Shares issuable upon
the exercise of such Warrants or other securities or property to which such
holder is entitled hereunder, together with cash as provided in Section 9
hereof; provided that if any consolidation, merger or lease or sale of assets is
proposed to be effected by the Company as described in


<PAGE>   23

                                                                           22


Section 8(m) hereof, or a tender offer or an exchange offer for shares of Common
Stock shall be made, upon such surrender of Warrants and payment of the Exercise
Price as aforesaid, the Warrant Agent shall, as soon as possible, but in any
event not later than two business days thereafter, deliver or cause to be
delivered the full number of Warrant Shares issuable upon the exercise of such
Warrants in the manner described in this sentence or other securities or
property to which such holder is entitled hereunder, together with cash as
provided in Section 9 hereof. Such certificate or certificates shall be deemed
to have been issued and any person so designated to be named therein shall be
deemed to have become a holder of record of such Warrant Shares as of the date
of the surrender of such Warrants and payment of the Exercise Price.

                  (d) The Warrants shall be exercisable, at the election of the
holders thereof, either in full or from time to time in part. If less than all
the Warrants represented by a Warrant Certificate are exercised, such Warrant
Certificate shall be surrendered and a new Warrant Certificate of the same tenor
and for the number of Warrants which were not exercised shall be executed by the
Company and delivered to the Warrant Agent and the Warrant Agent shall
countersign the new Warrant Certificate, registered in such name or names as may
be directed in writing by the holder, and shall deliver the new Warrant
Certificate to the Person or Persons entitled to receive the same.

                  (e) All Warrant Certificates surrendered upon exercise of
Warrants shall be cancelled by the Warrant Agent. Such cancelled Warrant
Certificates shall then be disposed of by the Warrant Agent in a manner
satisfactory to the Company. The Warrant Agent shall account promptly to the
Company with respect to Warrants exercised and concurrently pay to the Company
all monies received by the Warrant Agent for the purchase of the Warrant Shares
through the exercise of such Warrants.

                  (f) The Warrant Agent shall keep copies of this Agreement and
any notices given or received hereunder available for inspection by the holders
during normal business hours at its office. The Company shall supply the Warrant
Agent from time to time with such numbers of copies of this Agreement as the
Warrant Agent may request.

                  SECTION 5. PAYMENT OF TAXES.
                             -----------------

                  The Company will pay all documentary stamp taxes attributable
to the initial issuance of Warrant Shares upon the exercise of Warrants;
provided that the Company shall not be required to pay any tax or taxes which
may be payable in respect of any transfer involved in the issue of any Warrant
Certificates or any certificates for Warrant Shares in a name other than that of
the registered holder of a Warrant Certificate surrendered upon the exercise of
a Warrant, and the Company shall not be required to issue or deliver such
Warrant Certificates unless or until the person or persons requesting the
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

                                                                              23

                  SECTION 6. RESERVATION OF WARRANT SHARES.

                  (a) The Company will at all times reserve and keep available,
free from preemptive rights, out of the aggregate of its authorized but unissued
Common Stock or its authorized and issued Common Stock held in its treasury, for
the purpose of enabling it to satisfy any obligation to issue Warrant Shares
upon exercise of Warrants, the maximum number of shares of Common Stock which
may then be deliverable upon the exercise of all outstanding Warrants.

                  (b) The Company or, if appointed, the transfer agent for the
Common Stock (the "TRANSFER AGENT") and every subsequent transfer agent for any
shares of the Company"s capital stock issuable upon the exercise of any of the
rights of purchase aforesaid will be irrevocably authorized and directed at all
times to reserve such number of authorized shares as shall be required for such
purpose. The Company will keep a copy of this Agreement on file with the
Transfer Agent and with every subsequent transfer agent for any shares of the
Company"s capital stock issuable upon the exercise of the rights of purchase
represented by the Warrants. The Warrant Agent is hereby irrevocably authorized
to requisition from time to time from such Transfer Agent the stock certificates
required to honor outstanding Warrants upon exercise thereof in accordance with
the terms of this Agreement. The Company will supply such Transfer Agent with
duly executed certificates for such purposes and will provide or otherwise make
available any cash which may be payable as provided in Section 9 hereof. The
Company will furnish such Transfer Agent a copy of all notices of adjustments,
and certificates related thereto, transmitted to each holder pursuant to Section
11 hereof.

                  (c) Before taking any action which would cause an adjustment
pursuant to Section 8 hereof to reduce the Exercise Price below the then par
value (if any) of the Warrant Shares, the Company will take any corporate action
which may, in the opinion of its counsel (which may be counsel employed by the
Company), be necessary in order that the Company may validly and legally issue
fully paid and nonassessable Warrant Shares at the Exercise Price as so
adjusted.

                  (d) The Company covenants that all Warrant Shares which may be
issued upon exercise of Warrants will, upon issue, be fully paid, nonassessable,
free of preemptive rights and free from all taxes, liens, charges and security
interests with respect to the issuance thereof.

                  SECTION 7. OBTAINING STOCK EXCHANGE LISTINGS.
                             ----------------------------------

                  The Company will from time to time take all action which may
be necessary so that the Warrant Shares, immediately upon their issuance upon
the exercise of Warrants, will be listed on the principal securities exchanges,
automated quotation systems or other markets within the United States of
America, if any, on which other shares of Common Stock are then listed, if any.

                  SECTION 8. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT
                                                                        -------
SHARES ISSUABLE.
- - ----------------

                  The Exercise Price and the number of Warrant Shares issuable
upon the exercise of each Warrant are subject to adjustment from time to time
upon the occurrence of the events enumerated in this Section 8. For purposes of
this Section 8, "COMMON STOCK" means shares now or hereafter authorized of any
class of common stock of the Company and any other stock of the Company, however
designated, that has the right (subject to any prior rights of any class or
series of preferred stock) to participate in any distribution of the assets or
earnings of the Company without limit as to per share amount.

                  (a) ADJUSTMENT FOR CHANGE IN CAPITAL STOCK.

                  If the Company (i) pays a dividend or makes a distribution on
its Common Stock in shares of its Common Stock, (ii) subdivides its outstanding
shares of Common Stock into a greater number of shares, (iii) combines its
outstanding shares of Common Stock into a smaller number of shares, (iv) makes a
distribution on its Common Stock in shares of its capital stock other than
Common Stock or (v) issues by reclassification of its Common Stock any shares of
its capital stock, then the Exercise Price in effect immediately prior to such
action shall be proportionately adjusted so that the holder of any Warrant
thereafter exercised may receive the aggregate number and kind of shares of
capital stock of the Company which he would have owned immediately following
such action if such Warrant had been exercised immediately prior to such action.

                  The adjustment shall become effective immediately after the
record date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or reclassification.
If, after an adjustment, a holder of a Warrant upon exercise of it may receive
shares of two or more classes of capital stock of the Company, the Company shall
determine, in good faith, the allocation of the adjusted Exercise Price between
the classes of capital stock. After such allocation, the exercise privilege and
the Exercise Price of each class of capital stock shall thereafter be subject to
adjustment on terms comparable to those applicable to Common Stock in this
Section 8. Such adjustment shall be made successively whenever any event listed
above shall occur.

                                                                              25

                  (b) Adjustment for Rights Issue.

                   If the Company distributes any rights, options or warrants to
all holders of its Common Stock entitling them for a period expiring within 45
days after the record date mentioned below to purchase shares of Common Stock at
a price per share less than the Fair Value (as defined herein) per share on that
record date, the Exercise Price shall be adjusted in accordance with the
formula:

                                            O    +      N x P
                                                      ---------
                     E'   =    E     x                    M
                                             -------------------------
                                                    O + N
where:
         E'       =        the adjusted Exercise Price.
         E        =        the current Exercise Price.
         O        =        the number of shares of Common Stock outstanding on 
                           the record date. 
         N        =        the number of additional shares of Common Stock to 
                           be issued pursuant to such rights,
                           options or warrants.
         P        =        the price per share of the additional shares. 
         M        =        the Fair Value per share of Common Stock on the 
                           record date.

                  The adjustment shall be made successively whenever any such
rights, options or warrants are issued and shall become effective immediately
after the record date for the determination of stockholders entitled to receive
the rights, options or warrants. If at the end of the period during which such
rights, options or warrants are exercisable, not all rights, options or warrants
shall have been exercised, the Exercise Price shall be immediately readjusted to
what it would have been if "N" in the above formula had been the number of
shares actually issued.

                  (c) Adjustment for Other Distributions.

                  If the Company distributes to all holders of its Common Stock
any of its assets or debt securities or any rights or warrants to purchase debt
securities, assets or other securities of the Company, the Exercise Price shall
be adjusted in accordance with the formula:

                                                  M    -    F
                     E"   =    E     x      ----------------
                                                       M

where:
         E"       =        the adjusted Exercise Price.
<PAGE>   27
                                                                              26


         E        =        the current Exercise Price.
         M        =        the Fair Value per share of Common Stock on the 
                           record date mentioned below. 
         F        =        the fair market value on the record date of the
                           assets, securities, rights or warrants to be 
                           distributed in respect of one share of Common
                           Stock as determined in good faith by the Board of
                           Directors of the Company (the "Board of Directors").

                  The adjustment shall be made successively whenever any such
distribution is made and shall become effective immediately after the record
date for the determination of stockholders entitled to receive the distribution.

                  This Section 8(c) does not apply to cash dividends or cash
distributions paid out of consolidated current or retained earnings as shown on
the books of the Company prepared in accordance with generally accepted
accounting principles. Also, this Section 8(c) does not apply to rights, options
or warrants referred to in Section 8(b) hereof.

                  (d) Adjustment for Common Stock Issue.

                  If the Company issues shares of Common Stock for a
consideration per share less than the Fair Value per share on the date the
Company fixes the offering price of such additional shares, the Exercise Price
shall be adjusted in accordance with the formula:

                                                     P
                                                   -----
                   E'   =    E     x      O    +    M
                                             -------------------
                                                      A

where:
         E'       =        the adjusted Exercise Price.
         E        =        the then current Exercise Price.
         O        =        the number of shares outstanding immediately prior
                           to the issuance of such additional shares.
         P        =        the aggregate consideration received for the 
                           issuance of such additional shares. 
         M        =        the Fair Value per share on the date of issuance
                           of such additional shares.
         A        =        the number of shares outstanding immediately after 
                           the issuance of such additional shares.

                  The adjustment shall be made successively whenever any such
issuance is made, and shall become effective immediately after such issuance.

                  This subsection (d) does not apply to:

                           (1) any of the transactions described in subsections
         (a), (b) and (c) of this Section 8,

                           (2) the exercise of Warrants or any other rights,
         options or warrants to purchase Common Stock outstanding on the date
         hereof, or the conversion or exchange of other securities convertible
         or exchangeable for Common Stock the issuance of which caused an
         adjustment to be made under Section 8(e),

                           (3) Common Stock issued to the Company's employees
         (or employees of its subsidiaries) under bona fide employee benefit
         plans adopted by the Board of Directors and approved by the holders of
         Common Stock when required by law, if such Common Stock would otherwise
         be covered by this subsection (d) (but only to the extent that the
         aggregate number of shares excluded hereby and issued after the date of
         this Warrant Agreement shall not exceed 5% of the Common Stock
         outstanding at the time of the adoption of each such plan, exclusive of
         anti-dilution adjustments thereunder),

                           (4) Common Stock issued to shareholders of any person
         which merges into the Company, or with a subsidiary of the Company, in
         proportion to their stock holdings of such person immediately prior to
         such merger, upon such merger, provided that if such person is an
         Affiliate of the Company, the Board of Directors shall have obtained a
         fairness opinion from a nationally recognized investment banking,
         appraisal or valuation firm, which is not an Affiliate of the Company,
         stating that the consideration received in such merger is fair to the
         Company from a financial point of view, or

                           (5) the issuance of shares of Common Stock pursuant
         to rights, options or warrants which were originally issued in a
         Non-Affiliate Sale (as defined below) together with one or more other
         securities as part of a unit at a price per unit.

                  (e) Adjustment for Convertible Securities Issue.

                  If the Company issues any securities convertible into or
exchangeable for Common Stock (other than securities issued in transactions
described in subsections (b) and (c) of this Section 8) for a consideration per
share of Common Stock initially deliverable upon conversion or exchange of such
securities less than the Fair Value per share on the date of issuance of such
securities, the Exercise Price shall be adjusted in accordance with this
formula:

                                                        P
                                                      -----
                                              O    +    M
                    E"   =    E     x      ----------------

                                                                              28


                             O    +     D

where:
         E'       =        the adjusted Exercise Price.
         E        =        the then current Exercise Price.
         O        =        the number of shares outstanding immediately prior 
                           to the issuance of such securities. 
         P        =        the aggregate consideration received for the
                           issuance of such securities. 
         M        =        the Fair Value per share on the date
                           of issuance of such securities. 
         D        =        the maximum number of shares deliverable upon
                           conversion or in exchange for such securities at the
                           initial conversion or exchange rate.

                  The adjustment shall be made successively whenever any such
                  issuance is made, and shall become effective immediately after
                  such issuance.

                  If all of the Common Stock deliverable upon conversion or
exchange of such securities have not been issued when such securities are no
longer outstanding, then the Exercise Price shall promptly be readjusted to the
Exercise Price which would then be in effect had the adjustment upon the
issuance of such securities been made on the basis of the actual number of
shares of Common Stock issued upon conversion or exchange of such securities.

                  This subsection (e) does not apply to convertible securities
issued to shareholders of any person which merges into the Company, or with a
subsidiary of the Company, in proportion to their stock holdings of such person
immediately prior to such merger, upon such merger, provided that if such person
is an Affiliate of the Company, the Board of Directors shall have obtained a
fairness opinion from a nationally recognized investment banking, appraisal or
valuation firm, which is not an Affiliate of the Company, stating that the
consideration received in such merger is fair to the Company from a financial
point of view.

                  (f) Consideration Received.

                  For purposes of any computation respecting consideration
received pursuant to subsections (d), and (e) of this Section 8, the following
shall apply:

                           (1) in the case of the issuance of shares of Common
         Stock for cash, the consideration shall be the amount of such cash,
         provided that in no case shall any deduction be made for any
         commissions, discounts or other expenses incurred by the Company for
         any underwriting of the issue or otherwise in connection therewith;

                           (2) in the case of the issuance of shares of Common
         Stock for a consideration in whole or in part other than cash, the
         consideration other than cash shall be deemed to be the fair market
         value thereof as determined in good faith by the Board of

<PAGE>   30
                                                                              29


         Directors (irrespective of the accounting treatment thereof), whose
         determination shall be conclusive, and described in a Board resolution
         which shall be filed with the Warrant Agent;

                           (3) in the case of the issuance of securities
         convertible into or exchangeable for shares, the aggregate
         consideration received therefor shall be deemed to be the consideration
         received by the Company for the issuance of such securities plus the
         additional minimum consideration, if any, to be received by the Company
         upon the conversion or exchange thereof (the consideration in each case
         to be determined in the same manner as provided in clauses (1) and (2)
         of this subsection); and

                           (4) in the case of the issuance of shares of Common
         Stock pursuant to rights, options or warrants which rights, options or
         warrants were originally issued together with one or more other
         securities as part of a unit at a price per unit, the consideration
         shall be deemed to be the fair value of such rights, options or
         warrants at the time of issuance thereof as determined in good faith by
         the Board of Directors whose determination shall be conclusive and
         described in a Board resolution which shall be filed with the Warrant
         Agent plus the additional minimum consideration, if any, to be received
         by the Company upon the exercise, conversion or exchange thereof (as
         determined in the same manner as provided in clauses (1) and (2) of
         this subsection).

                  (g) Fair Value.

                  In Sections 8(d) and (e) hereof, the "Fair Value" per security
at any date of determination shall be (1) in connection with a sale by the
Company to a party that is not an Affiliate of the Company in an arm's-length
transaction (a "NON-AFFILIATE SALE"), the price per security at which such
security is sold and (2) in connection with any sale by the Company to an
Affiliate of the Company, (a) the last price per security at which such security
was sold in a Non-Affiliate Sale within the three-month period preceding such
date of determination or (b) if clause (a) is not applicable, the fair market
value of such security determined in good faith by (i) a majority of the Board
of Directors, including a majority of the Disinterested Directors, and approved
in a Board resolution delivered to the Warrant Agent or (ii) a nationally
recognized investment banking, appraisal or valuation firm, which is not an
Affiliate of the Company, in each case, taking into account, among all other
factors deemed relevant by the Board of Directors or such investment banking,
appraisal or valuation firm, the trading price and volume of such security on
any national securities exchange or automated quotation system on which such
security is traded. Notwithstanding the foregoing, any sale to Donaldson, Lufkin
& Jenrette Securities Corporation (or any successor thereto) pursuant to an
underwritten public offering registered under the Securities Act shall be deemed
to be and treated as a Non-Affiliate Sale.

                  In Sections 8(b) and (c) hereof, the "Fair Value" per security
at any date of determination shall be (a) the last price per security at which
such security was sold by the

                                                                              30


Company in a Non-Affiliate Sale within the three-month period preceding such
date of determination or (b) if clause (a) is not applicable, the fair market
value of such security determined in good faith by (i) a majority of the Board
of Directors, including a majority of the Disinterested Directors, and approved
in a Board resolution delivered to the Warrant Agent or (ii) a nationally
recognized investment banking, appraisal or valuation firm, which is not an
Affiliate of the Company, in each case, taking into account, among all other
factors deemed relevant by the Board of Directors or such investment banking,
appraisal or valuation firm, the trading price and volume of such security on
any national securities exchange or automated quotation system on which such
security is traded.

                  For purposes of this Section 8(g), "Disinterested Director"
means, in connection with any issuance of securities that gives rise to a
determination of the Fair Value thereof, each member of the Board of Directors
who is not an officer, employee, director or other Affiliate of the party to
whom the Company is proposing to issue the securities giving rise to such
determination.

                  For purposes of this Section 8(g), "AFFILIATE" of any
specified Person means (A) any other Person directly or indirectly controlling
or controlled by or under direct or indirect common control with such specified
Person and (B) any director, officer or employee of such specified person. For
purposes of this definition "CONTROL" (including, with correlative meanings, the
terms "CONTROLLING," "CONTROLLED BY" and "UNDER COMMON CONTROL WITH") as used
with respect to any Person, shall mean the possession, directly or indirectly,
of the power to direct or cause the direction of the management or policies of
such Person, whether through the ownership of voting securities, by agreement or
otherwise.

                  (h) When De Minimis Adjustment May Be Deferred.

                  No adjustment in the Exercise Price need be made unless the
adjustment would require an increase or decrease of at least 1% in the Exercise
Price. Any adjustments that are not made shall be carried forward and taken into
account in any subsequent adjustment. All calculations under this Section 8
shall be made to the nearest cent or to the nearest 1/100th of a share, as the
case may be, it being understood that no such rounding shall be made under
subsection (p).

                  (i) When No Adjustment Required.

                  No adjustment need be made for a transaction referred to
Section 8(a), (b), (c), (d), (e) or (f) hereof, if Warrant holders are to
participate (without being required to exercise their Warrants) in the
transaction on a basis and with notice that the Board of Directors determines to
be fair and appropriate in light of the basis and notice on which holders of
Common Stock participate in the transaction. No adjustment need be made for (i)
rights to purchase Common Stock pursuant to a Company plan for reinvestment of
dividends or interest or (ii) a change in the par value or no par value of the
Common Stock. To the extent the Warrants become convertible into cash, no
adjustment need be made thereafter as to the cash. Interest will not accrue on
the cash.

                  (j) Notice of Adjustment.

                  Whenever the Exercise Price is adjusted, the Company shall
provide the notices required by Section 10 hereof.

                  (k) Notice of Certain Transactions.

                  If (i) the Company takes any action that would require an
adjustment in the Exercise Price pursuant to Section 8(a), (b), (c), (d), (e) or
(f) hereof and if the Company does not arrange for Warrant holders to
participate pursuant to Section 8(i) hereof, (ii) the Company takes any action
that would require a supplemental Warrant Agreement pursuant to Section 8(l)
hereof or (iii) there is a liquidation or dissolution of the Company, then the
Company shall mail to Warrant holders a notice stating the proposed record date
for a dividend or distribution or the proposed effective date of a subdivision,
combination, reclassification, consolidation, merger, transfer, lease,
liquidation or dissolution. The Company shall mail the notice at least 15 days
before such date. Failure to mail the notice or any defect in it shall not
affect the validity of the transaction.

                  (l) Reorganization of Company.

                  Immediately after the date hereof, if the Company consolidates
or merges with or into, or transfers or leases all or substantially all its
assets to, any person, upon consummation of such transaction the Warrants shall
automatically become exercisable for the kind and amount of securities, cash or
other assets which the holder of a Warrant would have owned immediately after
the consolidation, merger, transfer or lease if the holder had exercised the
Warrant immediately before the effective date of the transaction. Concurrently
with the consummation of such transaction, the corporation formed by or
surviving any such consolidation or merger if other than the Company, or the
person to which such sale or conveyance shall have been made, shall enter into
(i) a supplemental Warrant Agreement so providing and further providing for
adjustments which shall be as nearly equivalent as may be practical to the
adjustments provided for in this Section 8(l) and (ii) a supplement to the
Warrant Registration Rights Agreement providing for the assumption of the
Company's obligations thereunder. The successor Company shall mail to Warrant
holders a notice describing the supplemental Warrant Agreement and Warrant
Registration Rights Agreement. If the issuer of securities deliverable upon
exercise of Warrants under the supplemental Warrant Agreement is an affiliate of
the formed, surviving, transferee or lessee corporation, that issuer shall join
in the supplemental Warrant Agreement and Warrant Registration Rights Agreement.
If this Section 8(l) applies, Sections 8(a), (b), (c), (d), (e) and (f) hereof
do not apply.

                  (m) Company Determination Final.

                  Any determination that the Company or the Board of Directors
must make pursuant to Section 8(a), (c), (d), (e), (f), (g), (h) or (i) hereof
is conclusive.

                  (n) Warrant Agent's Disclaimer.

                  The Warrant Agent has no duty to determine when an adjustment
under this Section 8 should be made, how it should be made or what it should be.
The Warrant Agent has no duty to determine whether any provisions of a
supplemental Warrant Agreement under Section 8(l) hereof are correct. The
Warrant Agent makes no representation as to the validity or value of any
securities or assets issued upon exercise of Warrants. The Warrant Agent shall
not be responsible for the Company's failure to comply with this Section 8.

                                                                              33

                  (o) When Issuance or Payment May Be Deferred.

                  In any case in which this Section 8 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event (i) issuing to the holder of any Warrant exercised after such record date
the Warrant Shares and other capital stock of the Company, if any, issuable upon
such exercise over and above the Warrant Shares and other capital stock of the
Company, if any, issuable upon such exercise on the basis of the Exercise Price
and (ii) paying to such holder any amount in cash in lieu of a fractional share
pursuant to Section 10 hereof; provided that the Company shall deliver to such
holder a due bill or other appropriate instrument evidencing such holder"s right
to receive such additional Warrant Shares, other capital stock and cash upon the
occurrence of the event requiring such adjustment.

                  (p) Adjustment in Number of Shares.

                  Upon each adjustment of the Exercise Price pursuant to this
Section 8, each Warrant outstanding prior to the making of the adjustment in the
Exercise Price shall thereafter evidence the right to receive upon payment of
the adjusted Exercise Price that number of shares of Common Stock (calculated to
the nearest hundredth) obtained from the following formula:

                           N'   =    N     x     E
                                                ---
                                                 E"

where:
         N'       =        the adjusted number of Warrant Shares issuable upon 
                           exercise of a Warrant by payment of the adjusted 
                           Exercise Price.
         N        =        the number or Warrant Shares previously issuable
                           upon exercise of a Warrant by payment of the Exercise
                           Price prior to adjustment.
         E'       =        the adjusted Exercise Price.
         E        =        the Exercise Price prior to adjustment.

                  (q) Form of Warrants.

                  Irrespective of any adjustments in the Exercise Price or the
number or kind of shares purchasable upon the exercise of the Warrants, Warrants
theretofore or thereafter issued may continue to express the same price and
number and kind of shares as are stated in the Warrants initially issuable
pursuant to this Agreement.

                  The Company shall not be required to issue fractional Warrant
Shares on the exercise of Warrants. If more than one Warrant shall be presented
for exercise in full at the same time by the same holder, the number of full
Warrant Shares which shall be issuable upon the exercise thereof shall be
computed on the basis of the aggregate number of Warrant Shares purchasable on
exercise of the Warrants so presented. If any fraction of a Warrant Share would,
except for the provisions of this Section 9, be issuable on the exercise of any
Warrants (or specified portion thereof), the Company shall pay an amount in cash
equal to the Fair Value per Warrant Share, as determined on the day immediately
preceding the date the Warrant is presented for exercise, multiplied by such
fraction, computed to the nearest whole U.S. cent.

                  SECTION 10. NOTICES TO WARRANT HOLDERS.
                              ---------------------------

                  (a) Upon any adjustment of the Exercise Price pursuant to
Section 8 hereof, the Company shall promptly thereafter (i) cause to be filed
with the Warrant Agent a certificate of a firm of independent public accountants
of recognized standing selected by the Board of Directors of the Company (who
may be the regular auditors of the Company) setting forth the Exercise Price
after such adjustment and setting forth in reasonable detail the method of
calculation and the facts upon which such calculations are based and setting
forth the number of Warrant Shares (or portion thereof) issuable after such
adjustment in the Exercise Price, upon exercise of a Warrant and payment of the
adjusted Exercise Price, which certificate shall be conclusive evidence of the
correctness of the matters set forth therein, and (ii) cause to be given to each
of the registered holders of Warrants at the address appearing on the Warrant
register for each such registered holder written notice of such adjustments by
first-class mail, postage prepaid. Where appropriate, such notice may be given
in advance and included as a part of the notice required to be mailed under the
other provisions of this Section 10.

                  (b) In case:

                  (i) the Company shall authorize the issuance to all holders of
         shares of Common Stock of rights, options or warrants to subscribe for
         or purchase shares of Common Stock or of any other subscription rights
         or warrants;

                  (ii) the Company shall authorize the distribution to all
         holders of shares of Common Stock of evidences of its indebtedness or
         assets (other than dividends or cash distributions paid out of
         consolidated current or retained earnings as shown on the books of the
         Company prepared in accordance with generally accepted accounting
         principles or dividends payable in shares of Common Stock or
         distributions referred to in Section 10(a) hereof);

                  (iii) 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 of the conveyance or transfer of the properties and assets
         of the Company substantially as an entirety, or of any

         reclassification or change of Common Stock issuable upon exercise of
         the Warrants (other than a change in par value, or from par value to no
         par value, or from no par value to par value, or as a result of a
         subdivision or combination), or a tender offer or exchange offer for
         shares of Common Stock;

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

                  (v) the Company proposes to take any action (other than
         actions of the character described in Section 8(a) hereof) which would
         require an adjustment of the Exercise Price pursuant to Section 8
         hereof;

then the Company shall cause to be filed with the Warrant Agent and shall cause
to be given to each of the registered holders of Warrants at his address
appearing on the Warrant register, at least 20 days (or 10 days in any case
specified in clauses (i) or (ii) above) prior to the applicable record date
hereinafter specified, or promptly in the case of events for which there is no
record date, by first-class mail, postage prepaid, a written notice stating (x)
the date as of which the holders of record of shares of Common Stock to be
entitled to receive any such rights, options, warrants or distribution are to be
determined, (y) the initial expiration date set forth in any tender offer or
exchange offer for shares of Common Stock, or (z) the date on which any such
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up is expected to become effective or consummated, and the date as of which it
is expected that holders of record of shares of Common Stock shall be entitled
to exchange such shares for securities or other property, if any, deliverable
upon such reclassification, consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding up. The failure to give the notice required
by this Section 11 or any defect therein shall not affect the legality or
validity of any distribution, right, option, warrant, consolidation, merger,
conveyance, transfer, dissolution, liquidation or winding up, or the vote upon
any action.

                  (c) Nothing contained in this Agreement or in any of the
Warrant Certificates shall be construed as conferring upon the holders of
Warrants the right to vote or to consent or to receive notice as stockholders in
respect of the meetings of stockholders or the election of directors of the
Company or any other matter, or any rights whatsoever as stockholders of the
Company.

AGENT.
- - ------

                  (a) Any corporation into which the Warrant Agent may be merged
or with which it may be consolidated, or any corporation resulting from any
merger or consolidation to which the Warrant Agent shall be a party, or any
corporation succeeding to the business of the Warrant Agent, shall be the
successor to the Warrant Agent hereunder without the execution or

                                                                              36


filing of any paper or any further act on the part of any of the parties hereto,
provided that such corporation would be eligible for appointment as a successor
warrant agent under the provisions of Section 13 hereof. In case at the time
such successor to the Warrant Agent shall succeed to the agency created by this
Agreement, and in case at that time any of the Warrant Certificates shall have
been countersigned but not delivered, any such successor to the Warrant Agent
may adopt the countersignature of the original Warrant Agent; and in case at
that time any of the Warrant Certificates shall not have been countersigned, any
successor to the Warrant Agent may countersign such Warrant Certificates either
in the name of the predecessor Warrant Agent or in the name of the successor to
the Warrant Agent; and in all such cases such Warrant Certificates shall have
the full force and effect provided in the Warrant Certificates and in this
Agreement.

                  (b) In case at any time the name of the Warrant Agent shall be
changed and at such time any of the Warrant Certificates shall have been
countersigned but not delivered, the Warrant Agent whose name has been changed
may adopt the countersignature under its prior name, and in case at that time
any of the Warrant Certificates shall not have been countersigned, the Warrant
Agent may countersign such Warrant Certificates either in its prior name or in
its changed name, and in all such cases such Warrant Certificates shall have the
full force and effect provided in the Warrant Certificates and in this
Agreement.

                  SECTION 12. WARRANT AGENT.
                              --------------

                  The Warrant Agent undertakes the duties and obligations
imposed by this Agreement upon the following terms and conditions, by all of
which the Company and the holders of Warrants, by their acceptance thereof,
shall be bound:

                  (a) The statements contained herein and in the Warrant
Certificates shall be taken as statements of the Company and the Warrant Agent
assumes no responsibility for the correctness of any of the same except such as
describe the Warrant Agent or action taken or to be taken by it. The Warrant
Agent assumes no responsibility with respect to the distribution of the Warrant
Certificates except as herein otherwise provided.

                  (b) The Warrant Agent shall not be responsible for any failure
of the Company to comply with any of the covenants contained in this Agreement
or in the Warrant Certificates to be complied with by the Company.

                  (c) The Warrant Agent may consult at any time with counsel
satisfactory to it (who may be counsel for the Company) and the Warrant Agent
shall incur no liability or responsibility to the Company or to any holder of
any Warrant Certificate in respect of any action taken, suffered or omitted by
it hereunder in good faith and in accordance with the opinion or the advice of
such counsel.
<PAGE>   38

                                                                              37

                  (d) The Warrant Agent shall incur no liability or
responsibility to the Company or to any holder of any Warrant Certificate for
any action taken in reliance on any Warrant Certificate, certificate of shares,
notice, resolution, waiver, consent, order, certificate, or other paper,
document or instrument believed by it to be genuine and to have been signed,
sent or presented by the proper party or parties.

                  (e) The Company agrees to pay to the Warrant Agent reasonable
compensation for all services rendered by the Warrant Agent in the execution of
this Agreement, to reimburse the Warrant Agent for all expenses, taxes and
governmental charges and other charges of any kind and nature incurred by the
Warrant Agent in the execution of this Agreement and to indemnify the Warrant
Agent and save it harmless against any and all liabilities, including judgments,
costs and counsel fees, for anything done or omitted by the Warrant Agent in the
execution of this Agreement except as a result of its negligence or bad faith.

                  (f) The Warrant Agent shall be under no obligation to
institute any action, suit or legal proceeding or to take any other action
likely to involve expense unless the Company or one or more registered holders
of Warrants shall furnish the Warrant Agent with reasonable security and
indemnity for any costs and expenses which may be incurred, but this provision
shall not affect the power of the Warrant Agent to take such action as it may
consider proper, whether with or without any such security or indemnity. All
rights of action under this Agreement or under any of the Warrants may be
enforced by the Warrant Agent without the possession of any of the Warrant
Certificates or the production thereof at any trial or other proceeding relative
thereto, and any such action, suit or proceeding instituted by the Warrant Agent
shall be brought in its name as Warrant Agent and any recovery of judgment shall
be for the ratable benefit of the registered holders of the Warrants, as their
respective rights or interests may appear.

                  (g) The Warrant Agent, and any stockholder, director, officer
or employee of it, may buy, sell or deal in any of the Warrants or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not Warrant Agent
under this Agreement. Nothing herein shall preclude the Warrant Agent from
acting in any other capacity for the Company or for any other legal entity.

                  (h) The Warrant Agent shall act hereunder solely as agent for
the Company, and its duties shall be determined solely by the provisions hereof.
The Warrant Agent shall not be liable for anything which it may do or refrain
from doing in connection with this Agreement except for its own negligence or
bad faith.

                  (i) The Warrant Agent shall not at any time be under any duty
or responsibility to any holder of any Warrant Certificate to make or cause to
be made any adjustment of the Exercise Price or number of the Warrant Shares or
other securities or property deliverable as provided in this Agreement, or to
determine whether any facts exist which may require any of

<PAGE>   39
                                                                              38


such adjustments, or with respect to the nature or extent of any such
adjustments, when made, or with respect to the method employed in making the
same. The Warrant Agent shall not be accountable with respect to the validity or
value or the kind or amount of any Warrant Shares or of any securities or
property which may at any time be issued or delivered upon the exercise of any
Warrant or with respect to whether any such Warrant Shares or other securities
will when issued be validly issued and fully paid and nonassessable, and makes
no representation with respect thereto.

                  SECTION 13. CHANGE OF WARRANT AGENT.
                              ------------------------

                  If the Warrant Agent shall become incapable of acting as
Warrant Agent, the Company shall appoint a successor to such Warrant Agent. If
the Company shall fail to make such appointment within a period of 30 days after
it has been notified in writing of such incapacity by the Warrant Agent or by
the registered holder of a Warrant Certificate, then the registered holder of
any Warrant may apply to any court of competent jurisdiction for the appointment
of a successor to the Warrant Agent. Pending appointment of a successor to such
Warrant Agent, either by the Company or by such a court, the duties of the
Warrant Agent shall be carried out by the Company. The holders of a majority of
the unexercised Warrants shall be entitled at any time to remove the Warrant
Agent and appoint a successor to such Warrant Agent. Such successor to the
Warrant Agent need not be approved by the Company or the former Warrant Agent.
After appointment the successor to the Warrant Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Warrant Agent without further act or deed; provided that the former
Warrant Agent shall deliver and transfer to the successor to the Warrant Agent
any property at the time held by it hereunder and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Failure to
give any notice provided for in this Section 13, however, or any defect therein,
shall not affect the legality or validity of the appointment of a successor to
the Warrant Agent.

                  SECTION 14. REPORTS.
                              --------

                  (a) Whether or not required by the rules and regulations of
the Commission, so long as any Warrants or the Warrant Shares are outstanding,
the Company shall furnish to the Warrant Agent and the holders of Warrants or
Warrant Shares (i) all quarterly and annual financial information that would be
required to be contained in a filing with the Commission on Forms 10-Q and 10-K
if the Company were required to file such Forms, including a "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and,
with respect to the annual information only, a report thereon by the Company's
certified independent accountants and (ii) all current reports that would be
required to be filed with the Commission on Form 8-K if the Company were
required to file such reports. In addition, whether or not required by the rules
and regulations of the Commission, the Company shall file a copy of all such
information and reports with the Commission for public availability (unless the

<PAGE>   40

                                                                              39

Commission shall not accept such a filing) and make such information available
to securities analysts and prospective investors upon request.

                  (b) The Company shall provide the Warrant Agent with a
sufficient number of copies of all such reports that the Warrant Agent may be
required to deliver to the holders of the Warrants and the Warrant Shares under
this Section 14.

                  SECTION 15. REGISTRATION.
                              -------------

                  Holders shall be able to exercise their Warrants only if a
registration statement relating to such exercise is then in effect, or the
exercise of such Warrants is exempt from the registration requirements of the
Securities Act, and such securities are qualified for sale or exempt from
qualification under the applicable securities laws of the states in which the
various holders of the Warrants or other persons to whom it is proposed that the
Warrant Shares be issued on exercise of the Warrants reside.

                  (a) The Company shall prepare and cause to be filed within 120
days of the issuance date of the Warrants with the Commission pursuant to Rule
415 under the Securities Act a shelf registration statement (the "Registration
Statement") on the appropriate form relating to the offer and sale by the
Company of the Warrant Shares to the holders of Warrants upon exercise of the
Warrants.

                  (b) The Company shall use its reasonable best efforts to cause
such Registration Statement to be declared effective by the Commission on or
before 150 days from the date of issuance of the Warrants.

                  (c) The Company shall use its reasonable best efforts to keep
the Registration Statement continuously effective under the Securities Act in
order to permit the prospectus included therein to be lawfully delivered by the
Company to the holders exercising the Warrants until the earlier of (i) two
years following the first date as of which no Warrants remain outstanding and
(ii) if all of the Warrants expire unexercised, the Expiration Date; provided
that, except as provided below with respect to any Black Out Period (as defined
herein), the Company shall be deemed not to have used its reasonable best
efforts to keep the Registration Statements effective during the requisite
period if it voluntarily takes any action that would result in it not being able
to offer and sell the Warrant Shares upon exercise of the Warrants during that
period, unless such action is required by applicable law. Notwithstanding the
foregoing, the Company shall not be required to amend or supplement the
Registration Statement, any related prospectus or any document incorporated
therein by reference, for a period (a "Black Out Period") not to exceed, for so
long as this Agreement is in effect, an aggregate of 60 days in any calendar
year, in the event that (i) an event occurs and is continuing as a result of
which the Registration Statements, any related prospectus or any document
incorporated therein by reference as then amended or supplemented would, in the
Company's good faith judgment, contain an untrue 



<PAGE>   41

                                                                              40

statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, and (ii)(A) the Company determines in its good
faith judgment that the disclosure of such event at such time would have a
material adverse effect on the business, operations or prospects of the Company
or (B) the disclosure otherwise relates to a material business transaction which
has not yet been publicly disclosed; provided, further, that such Black Out
Period shall be extended for any period, not to exceed an aggregate of 30 days
in any calendar year, during which the Commission is reviewing any proposed
amendment or supplement to the Registration Statement, any related prospectus or
any document incorporated therein by reference which has been filed by the
Company; and provided, further, that no Black Out Period may be in effect during
the three months prior to the Expiration Date.

                  (d) The Company shall cause the Registration Statement and the
related prospectus and any amendment or supplement thereto, as of the effective
date of the Registration Statement, amendment or supplement, (i) to comply in
all material respects with the applicable requirements of the Securities Act and
the rules and regulations of the Commission and (ii) not to contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

                  (e) The Company shall give prompt written notice to the
holders of the Warrants, the Initial Purchaser and the Warrant Agent of (i) the
effectiveness of the Registration Statement or any post-effective amendment
thereto, (ii) the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statements or the initiation or threatening of
any proceedings for that purpose, (iii) the receipt by the Company or its legal
counsel of any notification with respect to the suspension of the qualification
of the Warrant Shares for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose, (iv) the happening of any event
that requires the Company to make changes in the Registration Statements or the
prospectus in order to make the statements therein not misleading and (v) the
commencement and termination of any Black Out Period.

                  (f) The Company shall use its reasonable best efforts to
prevent the issuance or obtain the withdrawal of any order suspending the
effectiveness of the Registration Statements at the earliest possible time.

                  (g) Upon the occurrence of any event contemplated by Section
15(e)(iv) or (v) hereof (subject to the last sentence of Section 15(c) hereof)
the Company shall promptly prepare a post-effective amendment to the
Registration Statement or a supplement to the related prospectus or file any
other required document so that, as thereafter delivered to holders of the
Warrants, the prospectus will not contain an untrue statement of a material fact
or omit to state any material fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading and will
contain the current information required by the Securities Act.

                  (h) Not later than the effective date of the Registration
Statements, the Company will provide a CUSIP number for the Warrant Shares and
provide the Warrant Agent with printed certificates for the Warrant Shares in a
form eligible for deposit with the Depository Trust Company.

                  (i) The Company will comply with all rules and regulations of
the Commission to the extent and so long as they are applicable to the
Registration Statement.

                  (j) The Company shall register or qualify or cooperate with
the holders in connection with the registration or qualification of the Warrant
Shares for offer and sale by the Company upon exercise of the Warrants under the
securities or blue sky laws of such states of the United States as any holder
reasonably requests and do any and all other acts or things necessary or
advisable to enable such offer and sale in such jurisdictions; provided that the
Company shall not be required to (i) qualify to do business in any jurisdiction
in which it is not then so qualified or (ii) take any action which would subject
it to general service of process or to taxation in any jurisdiction in which it
is not then so subject.

                  (k) The Company shall bear all expenses incurred by it in
connection with the performance of its obligations under this Section 15.

                  (l) The Company acknowledges and agrees that any remedy at law
for breach of any provision of this Section 15 will be inadequate and that, in
addition to any other remedies that the holder may have, the holders shall be
entitled to the remedy of specific performance to ensure the Company performs
its obligations under this Section 15. The election of any one or more remedies
by the holders hereunder shall not constitute a waiver of the right to pursue
other available remedies.

                  (m) No person is entitled to include any securities of the
Company held by such person in, or to have such securities registered under, the
Registration Statement.

                        [Reverse of Warrant Certificate]


                  The Warrants evidenced by this Warrant Certificate are part of
a duly authorized issue of Warrants expiring at 5:00 p.m. New York City time on
August 15, 2007 entitling the holder on exercise to receive shares of Common
Stock, and are issued or to be issued pursuant to a Warrant Agreement dated as
of November 9, 1998 (the "Warrant Agreement"), duly executed and delivered by
the Company to National City Bank, as warrant agent (the "Warrant Agent"), which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a description of the rights, limitation
of rights, obligations, duties and immunities thereunder of the Warrant Agent,
the Company and the holders (the words "holders" or "holder" meaning the
registered holders or registered holder) of the Warrants. A copy of the Warrant
Agreement may be obtained by the holder hereof upon written request to the
Company.

                  Warrants may be exercised at any time on or after the
Separation Date and on or before 5:00 p.m. New York City time on August 15,
2007; provided that holders shall be able to exercise their Warrants only if a
registration statement relating to the Warrants Shares is then in effect, or the
exercise of such Warrants is exempt from the registration requirements of the
Securities Act of 1933, as amended (the "Securities Act"), and such securities
are qualified for sale or exempt from qualification under the applicable
securities laws of the states in which the various holders of the Warrants or
other persons to whom it is proposed that the Warrant Shares be issued on
exercise of the Warrants reside. The Company has agreed pursuant to the Warrant
Agreement and a Warrant Registration Rights Agreement dated as of November 9,
1998 (the "Warrant Registration Rights Agreement") to file within 120 days after
the issuance of the Warrants and use its reasonable best efforts to make
effective on or before 150 days after such date a shelf registration statement
on the appropriate form under the Securities Act, and to use its reasonable best
efforts to keep such registration statement continuously effective, subject to
certain exceptions, under the Securities Act in order to permit the resale of
the Warrants and Warrant Shares by the holders thereof and the issuance of
Warrants Shares upon exercise of Warrants resold pursuant to an effective
Registration Statement, subject to certain exceptions, until the earlier of (i)
two years following the first date as of which no Warrants remain outstanding
and (ii) if all of the Warrants expire unexercised, the Expiration Date.

                  In order to exercise all or any of the Warrants represented by
this Warrant Certificate, the holder must deliver to the Warrant Agent at its
New York corporate trust office set forth in Section 19 of the Warrant Agreement
this Warrant Certificate and the form of election to purchase on the reverse
hereof duly filled in and signed, which signature shall be medallion guaranteed
by an institution which is a member of a Securities Transfer Association
recognized signature guarantee program, and upon payment to the Warrant Agent
for the account of the Company of the Exercise Price, as adjusted as provided in
the Warrant Agreement, for the number of Warrant Shares in respect of which such
Warrants are then exercised. 
                                      A-1
<PAGE>   53
Notwithstanding the foregoing, Warrants may be exercised without the exchange of
funds pursuant to the net exercise provisions of Section 4 of the Warrant
Agreement. No adjustment shall be made for any dividends on any Common Stock
issuable upon exercise of this Warrant.


                  The Warrant Agreement provides that upon the occurrence of
certain events the Exercise Price set forth on the face hereof may, subject to
certain conditions, be adjusted. If the Exercise Price is adjusted, the Warrant
Agreement provides that the number of shares of Common Stock issuable upon the
exercise of each Warrant shall be adjusted. No fractions of a share of Common
Stock will be issued upon the exercise of any Warrant, but the Company will pay
the cash value thereof determined as provided in the Warrant Agreement.

                  Warrant Certificates, when surrendered at the office of the
Warrant Agent by the registered holder thereof in person or by legal
representative or attorney duly authorized in writing, may be exchanged, in the
manner and subject to the limitations provided in the Warrant Agreement, but
without payment of any service charge, for another Warrant Certificate or
Warrant Certificates of like tenor evidencing in the aggregate a like number of
Warrants.

                  Upon due presentation for registration of transfer of this
Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate
or Warrant Certificates of like tenor and evidencing in the aggregate a like
number of Warrants shall be issued to the transferee(s) in exchange for this
Warrant Certificate, subject to the limitations provided in the Warrant
Agreement, without charge except for any tax or other governmental charge
imposed in connection therewith.

                  The Company and the Warrant Agent may deem and treat the
registered holder(s) thereof as the absolute owner(s) of this Warrant
Certificate (notwithstanding any notation of ownership or other writing hereon
made by anyone), for the purpose of any exercise hereof, of any distribution to
the holder(s) hereof, and for all other purposes, and neither the Company nor
the Warrant Agent shall be affected by any notice to the contrary. Neither the
Warrants nor this Warrant Certificate entitles any holder hereof to any rights
of a stockholder of the Company.

         Re: Warrants

                  Reference is hereby made to the Warrant Agreement, dated as of
November 9, 1998 (the "WARRANT AGREEMENT"), between Insilco Holding Co., as
issuer (the "COMPANY"), and National City Bank, as warrant agent. Capitalized
terms used but not defined herein shall have the meanings given to them in the
Warrant Agreement.

                  In connection with our proposed purchase of____________
Definitive Warrants, we confirm that:

                  1. We understand that any subsequent transfer of the Warrants
or any interest therein is subject to certain restrictions and conditions set
forth in the Warrant Agreement and the undersigned agrees to be bound by, and
not to resell, pledge or otherwise transfer the Warrants or any interest therein
except in compliance with, such restrictions and conditions and the United
States Securities Act of 1933, as amended (the "SECURITIES ACT").

                  2. We understand that the offer and sale of the Warrants have
not been registered under the Securities Act, and that the Warrants and any
interest therein may not be offered or sold except as permitted in the following
sentence. We agree, on our own behalf and on behalf of any accounts for which we
are acting as hereinafter stated, that if we should sell the Warrants or any
interest therein, we will do so only (A) to the Company or any subsidiary
thereof, (B) in accordance with Rule 144A under the Securities Act to a
"qualified institutional buyer" (as defined therein), (C) to an institutional
"accredited investor" (as defined below) that, prior to such transfer, furnishes
(or has furnished on its behalf by a U.S. broker-dealer) to you and to the
Company a signed letter substantially in the form of this letter and, if
requested by the Company,

                                      D-1
<PAGE>   65

an Opinion of Counsel in form reasonably acceptable to the Company to the effect
that such transfer is in compliance with the Securities Act, (D) pursuant to the
provisions of Rule 144(k) under the Securities Act or (E) pursuant to an
effective registration statement under the Securities Act, and we further agree
to provide to any person purchasing the Definitive Warrant or beneficial
interest in a Global Warrant from us in a transaction meeting the requirements
of clauses (A) through (D) of this paragraph a notice advising such purchaser
that resales thereof are restricted as stated herein.

                  3. We understand that, on any proposed resale of the Warrants
or beneficial interest therein, we will be required to furnish to you and the
Company such certifications, legal opinions and other information as you and the
Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions. We further understand that the Warrants purchased by
us will bear a legend to the foregoing effect.

                  4. We are an institutional "accredited investor" (as defined
in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Warrants,
and we and any accounts for which we are acting are each able to bear the
economic risk of our or its investment.

                  5. We are acquiring the Warrants or beneficial interest
therein purchased by us for our own account or for one or more accounts (each of
which is an institutional "accredited investor") as to each of which we exercise
sole investment discretion.

                   We agree not to engage in any hedging transactions with
regard to the Warrants unless such hedging transactions are in compliance with
the Securities Act.

                  You and the Company are entitled to rely upon this letter and
are irrevocably authorized to produce this letter or a copy hereof to any
interested party in any administrative or legal proceedings or official inquiry
with respect to the matters covered hereby.

that notwithstanding the foregoing, any

                                                                             3

Affiliate of the Issuer may, with notice to the Issuer, require the Issuer to
keep the Registration Statement continuously effective for resales by such
Affiliate for so long as such Affiliate holds Warrants or Warrant Shares,
including as a result of any market-making activities or other trading
activities of such Affiliate. Notwithstanding the foregoing, the Issuer shall
not be required to amend or supplement the Registration Statement, any related
prospectus or any document incorporated therein by reference, for a period (a
"Black Out Period") not to exceed, for so long as this Agreement is in effect,
an aggregate of 60 days in any calendar year, in the event that (i) an event
occurs and is continuing as a result of which the Registration Statement, any
related prospectus or any document incorporated therein by reference as then
amended or supplemented would, in the Issuer's good faith judgment, contain an
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, and (ii)(A) the Issuer determines in its
good faith judgment that the disclosure of such event at such time would have a
material adverse effect on the business, operations or prospects of the Issuer
or (B) the disclosure otherwise relates to a material business transaction which
has not yet been publicly disclosed; provided that such Black Out Period shall
be extended for any period, not to exceed an aggregate of 30 days in any
calendar year, during which the Commission is reviewing any proposed amendment
or supplement to the Registration Statement, any related prospectus or any
document incorporated therein by reference which has been filed by the Issuer;
and provided, further, that no Black Out Period may be in effect during the
three months prior to the Expiration Date.

         (b) PROVISION BY HOLDERS OF CERTAIN INFORMATION IN CONNECTION WITH THE
REGISTRATION STATEMENT. No Holder of Transfer Restricted Securities may include
any of its Transfer Restricted Securities in any Registration Statement pursuant
to this Agreement unless and until such Holder furnishes to the Issuer in
writing, within 20 days after receipt of a request therefor, the information
specified in Item 507 or 508 of Regulation S-K, as applicable, of the Act for
use in connection with any Registration Statement or Prospectus or preliminary
Prospectus included therein. Each selling Holder agrees to promptly furnish
additional information required to be disclosed in order to make the information
previously furnished to the Issuer by such Holder not materially misleading.

SECTION 4. REGISTRATION PROCEDURES

         (a) In connection with the Registration Statement and any related
Prospectus required by this Agreement, the Issuer shall:

                  (i) use its reasonable best efforts to effect such
         registration to permit the sale of the Transfer Restricted Securities
         being sold in accordance with the intended method or methods of
         distribution thereof (as indicated in the information furnished to the
         Issuer pursuant to Section 3(b) hereof), and pursuant thereto the
         Issuer will prepare and file with the Commission a Registration
         Statement relating to the registration on any appropriate form under
         the Act, which form shall be available for the sale of the Transfer
         Restricted Securities in accordance with the intended method or methods
         of distribution thereof within the time periods and otherwise in
         accordance with the provisions hereof;

                  (ii) use its reasonable best efforts to keep such Registration
         Statement continuously effective and provide all requisite financial
         statements for the period specified in Section 3

                                                                             4
 
         of this Agreement. Upon the occurrence of any event that would cause
         any such Registration Statement or the Prospectus contained therein (A)
         to contain an untrue statement of 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 (B) not
         to be effective and usable for resale of Transfer Restricted Securities
         during the period required by this Agreement, the Issuer shall, subject
         to Section 3(a), file promptly an appropriate amendment to such
         Registration Statement or a supplement to the Prospectus, as
         applicable, curing such defect, and, in the case of an amendment, use
         its reasonable best efforts to cause such amendment to be declared
         effective as soon as practicable;

                  (iii) prepare and file with the Commission such amendments and
         post-effective amendments to the applicable Registration Statement as
         may be necessary to keep such Registration Statement effective for the
         applicable period set forth in Section 3; cause the Prospectus to be
         supplemented by any required Prospectus supplement, and as so
         supplemented to be filed pursuant to Rule_424 under the Act, and to
         comply fully with Rules 424, 430A and 462, as applicable, under the Act
         in a timely manner; and comply with the provisions of the Act with
         respect to the disposition of all securities covered by such
         Registration Statement during the applicable period in accordance with
         the intended method or methods of distribution by the sellers thereof
         set forth in such Registration Statement or supplement to the
         Prospectus;

                  (iv) advise the Initial Purchaser promptly and, if requested
         by the Initial Purchaser, confirm such advice in writing, (A) when the
         Prospectus or any Prospectus supplement or post-effective amendment has
         been filed, and, with respect to any applicable Registration Statement
         or any post-effective amendment thereto, when the same has become
         effective, (B) of any request by the Commission for amendments to the
         Registration Statement or amendments or supplements to the Prospectus
         or for additional information relating thereto, (C) of the issuance by
         the Commission of any stop order suspending the effectiveness of the
         Registration Statement under the Act or of the suspension by any state
         securities commission of the qualification of the Transfer Restricted
         Securities for offering or sale in any jurisdiction, or the initiation
         of any proceeding for any of the preceding purposes, and (D) of the
         existence of any fact or the happening of any event that makes any
         statement of a material fact made in the Registration Statement, the
         Prospectus, any amendment or supplement thereto or any document
         incorporated by reference therein untrue, or that requires the making
         of any additions to or changes in the Registration Statement in order
         to make the statements therein not misleading, or that requires the
         making of any additions to or changes in the Prospectus in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading. If at any time the Commission
         shall issue any stop order suspending the effectiveness of the
         Registration Statement, or any state securities commission or other
         regulatory authority shall issue an order suspending the qualification
         or exemption from qualification of the Transfer Restricted Securities
         under state securities or Blue Sky laws, the Issuer shall use its
         reasonable best efforts to obtain the withdrawal or lifting of such
         order at the earliest possible time;

                  (v) subject to Section 4(a)(ii), if any fact or event
         contemplated by Section 4(a)(iv)(D) hereof shall exist or have
         occurred, prepare a supplement or post-effective

         amendment to the Registration Statement or related Prospectus or any
         document incorporated therein by reference or file any other required
         document so that, as thereafter delivered to the purchasers of Transfer
         Restricted Securities, the Prospectus will not contain an 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;

                  (vi) furnish to the Initial Purchaser, before filing with the
         Commission, copies of any Registration Statement or any Prospectus
         included therein or any amendments or supplements to any such
         Registration Statement or Prospectus (including all documents
         incorporated by reference after the initial filing of such Registration
         Statement), which documents will be subject to the review and comment
         of such Persons, if any, for a period of at least five Business Days,
         and the Issuer will not file any such Registration Statement or
         Prospectus or any amendment or supplement to any such Registration
         Statement or Prospectus (including all such documents incorporated by
         reference) to which the Initial Purchaser shall reasonably object
         within five Business Days after the receipt thereof. The Initial
         Purchaser shall be deemed to have reasonably objected to such filing if
         such Registration Statement, amendment, Prospectus or supplement, as
         applicable, as proposed to be filed, contains an 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 fails to comply with the applicable
         requirements of the Act;

                  (vii) promptly prior to the filing of any document that is to
         be incorporated by reference into a Registration Statement or
         Prospectus, provide copies of such document to the Initial Purchaser,
         make the Issuer"s representatives available for discussion of such
         document and other customary due diligence matters, and include such
         information in such document prior to the filing thereof as the Initial
         Purchaser may reasonably request;

                  (viii) make available, at reasonable times, for inspection by
         the Initial Purchaser and any attorney or accountant retained by the
         Initial Purchaser, all financial and other records, pertinent corporate
         documents of the Issuer and cause the Issuer"s officers, directors and
         employees to supply all information reasonably requested by the Initial
         Purchaser, attorney or accountant in connection with such Registration
         Statement or any post-effective amendment thereto subsequent to the
         filing thereof and prior to its effectiveness;

                  (ix) if requested by the Initial Purchaser, promptly include
         in any Registration Statement or Prospectus, pursuant to a supplement
         or post-effective amendment if necessary, such information as the
         Initial Purchaser may reasonably request to have included therein,
         including, without limitation, information relating to the "Plan of
         Distribution" of the Transfer Restricted Securities and the use of the
         Registration Statement or Prospectus for market-making activities; and
         make all required filings of such Prospectus supplement or
         post-effective amendment as soon as practicable after the Issuer is
         notified of the matters to be included in such Prospectus supplement or
         post-effective amendment;

                  (x) furnish to the Initial Purchaser and each Holder upon
         request, without charge, at least one copy of the Registration
         Statement, as first filed with the Commission, and of each

         amendment thereto, including all documents incorporated by reference
         therein and all exhibits (including exhibits incorporated therein by
         reference);

                  (xi) deliver to the Initial Purchaser and each Holder, without
         charge, as many copies of the Prospectus (including each preliminary
         prospectus) and any amendment or supplement thereto as the Initial
         Purchaser or such Holder reasonably may request; the Issuer hereby
         consents to the use (in accordance with law and subject to Section 4(d)
         hereof) of the Prospectus and any amendment or supplement thereto by
         each selling Person in connection with the offering and the sale of the
         Transfer Restricted Securities covered by the Prospectus or any
         amendment or supplement thereto and all market-making activities of the
         Initial Purchaser, as the case may be;

                  (xii) upon the request of the Initial Purchaser, enter into
         such agreements (including underwriting agreements) and make such
         representations and warranties and take all such other actions in
         connection therewith in order to expedite or facilitate the disposition
         of the Transfer Restricted Securities pursuant to any applicable
         Registration Statement contemplated by this Agreement as may be
         reasonably requested by the Initial Purchaser in connection with any
         sale or resale pursuant to any applicable Registration Statement. In
         such connection, the Issuer shall:

                           (A) upon request of the Initial Purchaser, furnish
                  (or in the case of paragraphs (2) and (3), use its reasonable
                  best efforts to cause to be furnished) to the Initial
                  Purchaser, upon the effectiveness of the Registration
                  Statement:

                                    (1) a certificate, dated such date, signed
                           on behalf of the Issuer by (x) the President or any
                           Vice President and (y) a principal financial or
                           accounting officer of the Issuer, confirming, as of
                           the date thereof, the matters set forth in Sections
                           6(cc), 9(a) and 9(b) of the Purchase Agreement and
                           such other similar matters as such Person may
                           reasonably request;

                                    (2) an opinion, dated the date of
                           effectiveness of the Registration Statement, of
                           counsel for the Issuer covering matters similar to
                           those set forth in Sections 9(e) and (f) of the
                           Purchase Agreement and such other matters as the
                           Initial Purchaser may reasonably request, and in any
                           event including a statement to the effect that such
                           counsel has participated in conferences with officers
                           and other representatives of the Issuer,
                           representatives of the independent public accountants
                           for the Issuer and have considered the matters
                           required to be stated therein and the statements
                           contained therein, although such counsel has not
                           independently verified the accuracy, completeness or
                           fairness of such statements; and that such counsel
                           advises that, on the basis of the foregoing (relying
                           as to materiality to the extent such counsel deems
                           appropriate upon the statements of officers and other
                           representatives of the Issuer) and without
                           independent check or verification), no facts came to
                           such counsel"s attention that caused such counsel to
                           believe that the applicable Registration Statement,
                           at the time such Registration Statement or any
                           post-effective amendment thereto became effective
                           contained an untrue

                           statement of a material fact or omitted to state a
                           material fact required to be stated therein or
                           necessary to make the statements therein not
                           misleading, or that the Prospectus contained in such
                           Registration Statement as of its date contained an
                           untrue statement of a material fact or omitted to
                           state a material fact necessary in order to make the
                           statements therein, in the light of the circumstances
                           under which they were made, not misleading. Without
                           limiting the foregoing, such counsel may state
                           further that such counsel assumes no responsibility
                           for, and has not independently verified, the
                           accuracy, completeness or fairness of the financial
                           statements, notes and schedules and other financial
                           data included in any Registration Statement
                           contemplated by this Agreement or the related
                           Prospectus; and

                                    (3) a customary comfort letter, dated the
                           date of effectiveness of the Registration Statement,
                           from the Issuer"s independent accountants, in the
                           customary form and covering matters of the type
                           customarily covered in comfort letters to
                           underwriters in connection with underwritten
                           offerings, and affirming the matters set forth in the
                           comfort letters delivered pursuant to Section 9(h) of
                           the Purchase Agreement; and

                           (B) deliver such other documents and certificates as
                  may be reasonably requested by the Initial Purchaser to
                  evidence compliance with the matters covered in clause (A)
                  above and with any customary conditions contained in any
                  agreement entered into by the Issuer pursuant to this clause;

                  (xiii) prior to any public offering of Transfer Restricted
         Securities, cooperate with the selling Holders and their counsel in
         connection with the registration and qualification of the Transfer
         Restricted Securities under the securities or Blue Sky laws of such
         jurisdictions as the selling Holders may request and do any and all
         other acts or things necessary or advisable to enable the disposition
         in such jurisdictions of the Transfer Restricted Securities covered by
         the applicable Registration Statement; provided that the Issuer shall
         not be required to register or qualify as a foreign corporation where
         it is not now so qualified or to take any action that would subject it
         to the service of process in suits or to taxation, other than as to
         matters and transactions relating to the Registration Statement, in any
         jurisdiction where it is not now so subject;

                  (xiv) in connection with any sale of Transfer Restricted
         Securities that will result in such securities no longer being Transfer
         Restricted Securities, cooperate with the Holders to facilitate the
         timely preparation and delivery of certificates representing Transfer
         Restricted Securities to be sold and not bearing any restrictive
         legends; and to register such Transfer Restricted Securities in such
         denominations and such names as the selling Holders may request at
         least two Business Days prior to such sale of Transfer Restricted
         Securities;

                  (xv) use its reasonable best efforts to cause the disposition
         of the Transfer Restricted Securities covered by the Registration
         Statement to be registered with or approved by such other governmental
         agencies or authorities as may be necessary to enable the seller or
         sellers thereof to consummate the disposition of such Transfer
         Restricted Securities, subject to the

                                                                               8

          proviso contained in clause (xiii) above;

                  (xvi) provide a CUSIP number for all Transfer Restricted
         Securities not later than the effective date of a Registration
         Statement covering such Transfer Restricted Securities and provide the
         Warrant Agent with printed certificates for the Transfer Restricted
         Securities which are in a form eligible for deposit with The Depository
         Trust Company;

                  (xvii) otherwise use its reasonable best efforts to comply
         with all applicable rules and regulations of the Commission, and make

         applicable Registration Statement, as soon as practicable, a
         consolidated earnings statement meeting the requirements of Rule 158
         (which need not be audited) covering a twelve-month period beginning
         after the effective date of the Registration Statement (as such term is
         defined in Rule 158(c) under the Act); and

                  (xviii) provide promptly to the Initial Purchaser, upon
         request, each document filed with the Commission pursuant to the
         requirements of Section 13 or Section 15(d) of the Exchange Act.

         (b) RESTRICTIONS ON HOLDERS. Each Holder agrees by acquisition of a
Transfer Restricted Security and the Initial Purchaser agrees that, upon receipt
of the notice from the Issuer of the commencement of a Black Out Period (in each
case, a "Black Out Notice"), such Person will forthwith discontinue disposition
of Transfer Restricted Securities pursuant to the applicable Registration

by the Issuer with more recently dated Prospectuses or (ii) deliver to the
Issuer (at the Issuer"s expense) all copies, other than permanent file copies,
then in such Person"s possession of the Prospectus covering such Transfer
Restricted Securities that was current at the time of receipt of the Black Out
Notice.

SECTION 5. REGISTRATION EXPENSES

         All expenses incident to the Issuer"s performance of or compliance with

retained by the Issuer.

SECTION 6. INDEMNIFICATION

         (a) The Issuer agrees to indemnify and hold harmless each Holder, its
directors, officers and each Person, if any, who controls such Holder (within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act), from
and against any and all losses, claims, damages, liabilities, judgments,
(including, without limitation, any legal or other expenses incurred in
connection with investigating or defending any matter, including any action that
could give rise to any such losses, claims, damages, liabilities or judgments)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement, preliminary prospectus or Prospectus
(or any amendment or supplement thereto) provided by the Issuer to any Holder or
any prospective purchaser of Transfer Restricted Securities, or caused by any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities or judgments are
caused by an untrue statement or omission or alleged untrue statement or
omission that is based upon information relating to a Holder furnished in
writing to the Issuer by such Holder.

         (b) Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, to indemnify and hold harmless the Issuer, its directors and
officers, and each person, if any, who controls (within the meaning of Section
15 of the Act or Section 20 of the Exchange Act) the Issuer, to the same extent
as the foregoing indemnity from the Issuer set forth in Section 6(a) hereof, but
only with reference to information relating to such Holder furnished in writing
to the Issuer by such Holder expressly for use in any Registration Statement. In
no event shall any Holder, its directors, officers or any Person who controls
such Holder be liable or responsible for any amount in excess of the amount by
which the total amount received by such Holder with respect to its sale of
Transfer Restricted Securities pursuant to a Registration Statement exceeds (i)
the amount paid by such Holder for such Transfer Restricted Securities and (ii)
the amount of any damages that such Holder, its directors, officers or any
Person who controls such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.

         (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 6(a) or 6(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in writing,
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that,
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 6(a) and 6(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 6(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the indemnified party, unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action


<PAGE>   11
                                                                              10


(including any impleaded parties) include both the indemnified party and the
indemnifying party, and the indemnified party shall have been advised by such
counsel that there may be one or more legal defenses available to it which are
different from or additional to those available to the indemnifying party (in
which case the indemnifying party shall not have the right to assume the defense
of such action on behalf of the indemnified party). In any such case, the
indemnifying party shall not, in connection with any one action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all indemnified parties and all such fees and expenses shall be
reimbursed as they are incurred. Such firm shall be designated in writing by a
majority of the Holders, in the case of the parties indemnified pursuant to
Section 6(a), and by the Issuer, in the case of parties indemnified pursuant to
Section 6(b). The indemnifying party shall indemnify and hold harmless the
indemnified party from and against any and all losses, claims, damages,
liabilities and judgments by reason of any settlement of any action effected
with its written consent. Notwithstanding the foregoing, in the case of Section
6(a) hereof, any such settlement may be effected by the Initial Purchaser
without the Issuer"s written consent if the settlement is entered into more than
twenty Business Days after the Issuer shall have received a request from the
Initial Purchaser for reimbursement for the fees and expenses of counsel (in any
case where such fees and expenses are at the expense of the Issuer) and, prior
to the date of such settlement, the Issuer shall have failed to comply with such
reimbursement request. In the case of Section 6(a) hereof, the Issuer shall not,
without the prior written consent of the Initial Purchaser, effect any
settlement or compromise of, or consent to the entry of judgment with respect
to, any pending or threatened action in respect of which the indemnified party
is or could have been a party and indemnity or contribution may be or could have
been sought hereunder by the indemnified party, unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability on claims that are or could have been the subject
matter of such action and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of the
indemnified party. Notwithstanding the foregoing, in the case of Section 6(b)
hereof, any such settlement may be effected by the indemnified party without the
indemnifying party"s written consent if the settlement is entered into more than
twenty Business Days after the indemnifying party shall have received a request
from the indemnified party for reimbursement for the fees and expenses of
counsel (in any case where such fees and expenses are at the expense of the
Indemnified party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request. In the case
of Section 6(b) hereof, the indemnifying party shall not, without the prior
written consent of the indemnified party, effect any settlement or compromise
of, or consent to the entry of judgment with respect to, any pending or
threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

         (d) To the extent that the indemnification provided for in this Section
6 is unavailable to an indemnified party in respect of any losses, claims,
damages, liabilities or judgments referred to therein, then each indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such losses,
claims,



<PAGE>   12

                                                                              11

damages, liabilities or judgments (i) in such proportion as is appropriate to
reflect the relative benefits received by the Issuer, on the one hand, and the
Holders, on the other hand, from their sale of Transfer Restricted Securities or
(ii) if the allocation provided by clause 6(d)(i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause 6(d)(i) hereof but also the relative fault of the
Issuer, on the one hand, and of the Holder, on the other hand, in connection
with the statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative fault of the Issuer, on the one hand, and of the
Holder, on the other hand, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Issuer, on the one hand, or by the Holder, on the other hand,
and the parties" relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages,
liabilities or judgments referred to above shall be deemed to include, subject
to the limitations set forth in the second paragraph of Section 6(a), any legal
or other fees or expenses reasonably incurred by such indemnified party in
connection with investigating or defending any matter, including any action that
could have given rise to such losses, claims, damages, liabilities or judgments.

         The Issuer and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 6(d) were determined by pro
rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 6, no Holder, its directors, its
officers or any Person, if any, who controls such Holder shall be required to
contribute, in the aggregate, any amount in excess of the amount by which the
total received by such Holder with respect to the sale of Transfer Restricted
Securities pursuant to a Registration Statement exceeds (i) the amount paid by
such Holder for such Transfer Restricted Securities and (ii) the amount of any
damages which such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The Holders" obligations to contribute
pursuant to this Section 6(d) are several in proportion to the respective
principal amount of Transfer Restricted Securities held by each Holder hereunder
and not joint.

         (e) The Issuer agrees that the indemnity and contribution provisions of
this Section 6 shall apply to the Initial Purchaser to the same extent, on the
same conditions, as it applies to Holders.

SECTION 7. RULE 144

         The Issuer agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Issuer is subject to Section 13 or 15(d) of the Exchange Act, to make all
filings required thereby in a timely manner in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144.


<PAGE>   13
                                                                              12

SECTION 8. MISCELLANEOUS

         (a) REMEDIES. The Issuer acknowledges and agrees that any failure by
the Issuer to comply with its obligations under Section 3 hereof may result in
material irreparable injury to the Initial Purchaser or the Holders for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of any such failure,
the Initial Purchaser or any Holder may obtain such relief as may be required to
specifically enforce the Issuer"s obligations under Section 3 hereof. The Issuer
further agrees to waive the defense in any action for specific performance that
a remedy at law would be adequate.

         (b) NO INCONSISTENT AGREEMENTS. The Issuer will not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Issuer"s securities under any agreement
in effect on the date hereof.

         (c) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of this Section
8(c)(i), the Issuer has obtained the written consent of Holders of all
outstanding Transfer Restricted Securities, and (ii) in the case of all other
provisions hereof, the Issuer has obtained the written consent of Holders of a
majority of the outstanding principal amount of Transfer Restricted Securities
(excluding Transfer Restricted Securities held by the Issuer or its Affiliates);
provided that this Agreement may be amended without the consent of any Holder
pursuant to Section 11(l) of the Warrant Agreement.

         (d) THIRD PARTY BENEFICIARY. The Holders shall be third party
beneficiaries to the agreements granting rights to Holders made hereunder
between the Issuer, on the one hand, and the Initial Purchaser, on the other
hand, and shall have the right to enforce such agreements directly to the extent
they may deem such enforcement necessary or advisable to protect its rights or
the rights of Holders hereunder.

         (e) NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

         (f) SUCCESSORS AND ASSIGNS. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties,
including, without limitation, and without the need for an express assignment,
subsequent Holders; provided that nothing herein shall be deemed to permit any
assignment, transfer or other disposition of Transfer Restricted Securities in
violation of the terms hereof or of the Purchase Agreement or the Warrant
Agreement. If any transferee of any Holder shall acquire Transfer Restricted
Securities in any manner, whether by operation of law or otherwise, such
Transfer Restricted Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Transfer Restricted Securities such
Person shall be conclusively deemed to have agreed to be bound by and to perform
all of the terms and provisions of this Agreement, including the restrictions on
resale set forth in this Agreement and, if applicable, the Purchase Agreement,
and such Person shall be entitled to receive the benefits hereof.

         (g) COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

         (h) HEADINGS. The headings in this Agreement are for convenience of

CONFLICT OF LAW RULES THEREOF.

         (j) SEVERABILITY. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

         (k) ENTIRE AGREEMENT. This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect 
of the subject matter contained herein. There are no restrictions, promises, 
warranties or undertakings, other than those set forth or referred to herein 
with respect to the registration rights granted with respect to the Transfer 
Restricted Securities. This Agreement supersedes all prior agreements and 
understandings between the parties with respect to such subject matter.

DONALDSON, LUFKIN & JENRETTE 
SECURITIES CORPORATION 
277 Park Avenue New York,
New York 10172


Dear Sirs:



         Insilco Corporation, a Delaware corporation ("Insilco") and Insilco
Holding Co., a Delaware corporation ("Holdings" and together with Insilco, the
"Issuers"), propose to issue and sell to Donaldson, Lufkin & Jenrette
Securities Corporation (the "Initial Purchaser") 120,000 units (the
"Units"), each consisting of $1,000 principal amount of 12% Senior
Subordinated Notes due 2007 (the "Series A Notes") of Insilco and one warrant
(collectively, the "Warrants") to purchase 0.520 of a share of common stock of
Holdings, par value $0.001 per share (the "Common Stock"), subject to the
terms and conditions set forth herein. The Series A Notes are to be issued
pursuant to the provisions of an indenture (the "Indenture"), to be dated as
of the Closing Date (as defined below), between Insilco and Star Bank, N.A., as
trustee (the "Trustee"). The Series A Notes and the Series B Notes (as defined
below) issuable in exchange therefor are collectively referred to herein as the
"Notes." The Warrants will be issued pursuant to a warrant agreement to be
dated as of the Closing Date (the "Warrant Agreement") between Holdings and
National City Bank, as warrant agent (the "Warrant Agent"). Shares of Common
Stock of Holdings issuable upon exercise of the Warrants are collectively
referred to herein as the "Warrant Shares." The Units, the Notes, the Warrants
and the Warrant Shares are collectively referred to herein as the
"Securities." The Series A Notes and the Warrants will not be detachable or
separable until the first to occur of certain events specified in the Offering
Memorandum. Capitalized terms used but not defined herein shall have the
meanings given to such terms in the Indenture or the Warrant Agreement, as
applicable.

         All agreements, representations and warranties of the Issuers set forth
in this Agreement are made as of the date of this Agreement. This Agreement, the
Indenture, the Series A Notes, the Warrants, the Warrant Agreement, the A/B
Registration Rights Agreement (as defined), and the Warrant Registration Rights
Agreement (as defined) are collectively referred herein as the "Operative
Documents."
<PAGE>   3

         1.       OFFERING MEMORANDUM.

         The Units will be offered and sold to the Initial Purchaser pursuant to
one or more exemptions from the registration requirements under the Securities
Act of 1933, as amended (the "Securities Act"). The Issuer has prepared a
preliminary offering memorandum, dated October 30, 1998 (the "Preliminary
Offering Memorandum"), and a final offering memorandum, dated November 2, 1998
(the "Offering Memorandum"), relating to the Units.

         Upon original issuance thereof, and until such time as the same is no
longer required pursuant to the Indenture, the Series A Notes (and all
securities issued in exchange therefor, in substitution thereof or upon
conversion thereof) shall bear the following legend:

         "THIS SECURITY (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER THE
         U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") AND,
         ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
         WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
         PERSONS, EXCEPT AS SET FORTH IN THE NEXT SENTENCE. BY ITS ACQUISITION
         HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER:

         (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT) (A "QIB") OR (B) IT IS
         AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)
         (1), (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN

that the Initial Purchaser will make offers (the "Exempt Resales") of the
Units purchased hereunder on the terms set forth in the Offering Memorandum, as

believes to be "qualified institutional buyers" ("QIBs") as defined in Rule
144A under the Securities Act (the "Eligible Purchasers"). The Initial
Purchaser will offer the Units to Eligible Purchasers initially at a price equal

have the registration rights set forth in the registration rights agreement with
respect to the Series A Notes (the "A/B Registration Rights Agreement"), to be
dated the Closing Date, in substantially the form of Exhibit A hereto, for so
long as such Series A Notes constitute "Transfer Restricted Securities" (as

Registration Rights Agreement, Insilco will agree to file with the Securities
and Exchange Commission (the "Commission") under the circumstances set forth
therein, (i) a registration statement under the Securities Act (the "Exchange
Offer Registration Statement") relating to Insilco's 12% Senior Subordinated

Series A Notes (such offer to exchange being referred to as the "Exchange
Offer") and (ii) a shelf registration statement pursuant to Rule 415 under the
Securities Act (the "Note Shelf Registration Statement" and, together with the
Exchange Offer Registration Statement, the "Note Registration Statements")
relating to the resale by certain holders of the Series A Notes and to use its
reasonable best efforts to cause such Note Registration Statements to be
declared and remain effective and usable for the periods specified in the A/B
Registration Rights Agreement and to consummate the Exchange Offer.

         Holders (including subsequent transferees) of the Warrants will have
the registration rights with respect to the Warrants set forth in the warrant
registration rights agreement (the "Warrant Registration Rights Agreement,"
and together with the A/B Registration Rights Agreement, the "Registration
Rights Agreements"), to be dated the Closing Date, in substantially the form of
Exhibit B hereto, for so long as the Warrants or Warrant Shares constitute
"Transfer Restricted Securities" (as defined in the Warrant Registration
Rights Agreement). Pursuant to the Warrant Registration Rights Agreement,
Holdings will agree to file with the Commission under the circumstances set
forth therein, a shelf registration

         4.       DELIVERY AND PAYMENT.

         (a) Delivery of, and payment of the Purchase Price for, the Units shall
be made at the offices of Davis Polk & Wardwell or such other location as may be
mutually acceptable. Such delivery and payment shall be made at 9:00 a.m. New
York City time, on November 9, 1998, or at such other time on the same date or
such other date as shall be agreed upon by the Initial Purchaser and the Issuers
in writing. The time and date of such delivery and the payment for the Units are
herein called the "Closing Date."

         (b) One or more of the Units containing Series A Notes and Warrants in
definitive global form (collectively, the "Global Securities"), registered in
the name of Cede & Co., as nominee of The Depository Trust Company ("DTC"),
shall be delivered by the Issuers to the Initial Purchaser (or as the Initial
Purchaser directs), in each case, with any transfer taxes thereon duly paid by
the Issuers against payment by the Initial Purchaser of the portion of the
Purchase Price relating to the Units by wire transfer in immediately available
funds to the order of Insilco. The Global Securities shall be made available to
the Initial Purchaser for inspection not later than 9:30 a.m., New York City
time, on the business day immediately preceding the Closing Date.

         5. AGREEMENTS OF THE ISSUERS. Each Issuer hereby agrees with the
Initial Purchaser as follows:

         (a) To advise the Initial Purchaser promptly and, if requested by the
Initial Purchaser, confirm such advice in writing, (i) of the issuance by any
state securities commission of any stop order suspending the qualification or
exemption from qualification of any Units for offering or sale in any
jurisdiction designated by the Initial Purchaser pursuant to Section 5(e)
hereof, or the initiation of any proceeding by any state securities commission
or any other federal or state regulatory authority for such purpose, and (ii) of
the happening of any event during the period referred to in Section 5(c) below
that makes any statement of a material fact made in the Preliminary Offering
Memorandum or the Offering Memorandum untrue or that requires any additions to
or changes in the Preliminary Offering Memorandum or the Offering Memorandum in
order to make the statements therein not misleading. Each Issuer shall use its
reasonable best efforts to prevent the issuance of any stop order or order
suspending the qualification or exemption of any Securities under any state
securities or Blue Sky laws, and, if at any time any state securities commission
or other federal or state regulatory authority shall issue an order suspending
the qualification or exemption of any Securities under any state securities or
Blue Sky laws, each Issuer shall use its reasonable best efforts to obtain the
withdrawal or lifting of such order at the earliest possible time; provided,
however, that neither Issuer shall be required in connection therewith to
qualify as a foreign corporation in any jurisdiction in which it is not now so
qualified or to take any action that would subject it to general consent to
service of process or taxation, other than as to matters and transactions
relating to the Preliminary Offering Memorandum, the Offering Memorandum or
Exempt Resales, in any jurisdiction in which it is not now so subject.

the Initial Purchaser to the Issuers as many copies of the Preliminary Offering
Memorandum and the Offering Memorandum, and any amendments or supplements
thereto, as the Initial Purchaser may reasonably request for the time period
specified in Section 5(c). Subject to the Initial Purchaser's compliance with
its representations and warranties and agreements set forth in Section 7 hereof,
each Issuer consents to the use of the Preliminary Offering Memorandum and the
Offering Memorandum, and any amendments and supplements thereto required
pursuant hereto, by the Initial Purchaser in connection with Exempt Resales and
market-making activities.

         (c) During such period as, in the opinion of counsel for the Initial
Purchaser, an Offering Memorandum is required by law to be delivered in
connection with Exempt Resales by the Initial Purchaser and in connection with
market-making activities of the Initial Purchaser for so long as any Securities
are outstanding, (i) not to make any amendment or supplement to the Offering
Memorandum of which the Initial Purchaser shall not previously have been advised
or to which the Initial Purchaser shall reasonably object after being so advised
and (ii) to prepare promptly, upon the Initial Purchaser's reasonable request,
any amendment or supplement to the Offering Memorandum which may be necessary or
advisable in connection with such Exempt Resales or such market-making
activities.

         (d) If, during the period referred to in Section 5(c) above, any event
shall occur or condition shall exist as a result of which, in the opinion of
counsel to the Initial Purchaser, it becomes necessary to amend or supplement
the Offering Memorandum in order to make the statements therein, in the light of
the circumstances when such Offering Memorandum is delivered by the Initial
Purchaser, not misleading, or if, in the opinion of counsel to the Initial
Purchaser, it is necessary to amend or supplement the Offering Memorandum to
comply with any applicable law, forthwith to prepare an appropriate amendment or
supplement to such Offering Memorandum so that the statements therein, as so
amended or supplemented, will not, in the light of the circumstances when it is
so delivered, be misleading, or so that such Offering Memorandum will comply
with applicable law, and to furnish to the Initial Purchaser and such other
persons as the Initial Purchaser may designate such number of copies thereof as
the Initial Purchaser may reasonably request.

         (e) Prior to the sale of all Units pursuant to Exempt Resales as
contemplated hereby, to cooperate with the Initial Purchaser and counsel to the
Initial Purchaser in connection with the registration or qualification of the
Units for offer and sale to the Initial Purchaser and pursuant to Exempt Resales
under the securities or Blue Sky laws of such jurisdictions as the Initial
Purchaser may request and to continue such registration or qualification in
effect so long as required for Exempt Resales and to file such consents to
service of process or other documents as may be necessary in order to effect
such registration or qualification; provided, however, that neither Issuer shall
be required in connection therewith to qualify as a foreign entity in any
jurisdiction in which it is now so qualified or to take any action that would
subject it to general consent to service of process or taxation, other than as
to matters and transactions relating to the Preliminary Offering Memorandum, the
Offering Memorandum or Exempt Resales, in any jurisdiction in which it is now so
subject.

Shares to be issued upon the exercise of the Warrants and, when issued and
delivered upon the exercise of the Warrants against payment of the exercise
price as provided in the Warrant Agreement, the Warrant Shares will have been
validly issued and will be fully paid and non assessable, and the issuance of
the Warrant Shares will not be subject to any preemptive or similar rights.

         (m) The Registration Rights Agreements have been duly authorized by the
Issuer party thereto and, on the Closing Date, will have been duly executed and
delivered by such Issuer. When each Registration Rights Agreement has been duly
executed and delivered, such Registration Rights Agreement will be a valid and
binding agreement of such Issuer, enforceable against such Issuer in accordance
with its terms, except as (i) the enforceability thereof may be limited by
bankruptcy, insolvency or similar laws affecting creditors' rights generally,
(ii) rights of acceleration and the availability of equitable remedies may be
limited by equitable principles of general applicability and (iii) rights to
indemnity and contribution thereunder may be limited by applicable law. On the
Closing Date, the Registration Rights Agreements will conform as to legal
matters to the descriptions thereof in the Offering Memorandum.

         (n) (1) All of the indebtedness represented by the Series A Notes is
being incurred for proper purposes and in good faith. (2) As of the date hereof
(a) the fair value and present fair saleable value of the assets of Holdings and
its subsidiaries exceeds and would exceed their stated liabilities and
identified contingent liabilities, (b) Holdings and its subsidiaries should be
able to pay their debts as they become absolute and matured and (c) the capital
of Holdings and its subsidiaries is not and would not be unreasonably small for
the business in which it each of them is engaged.

         (o) Neither of the Issuers nor any of their subsidiaries is in
violation of their respective organizational documents or, except as otherwise
set forth in the Offering Memorandum, in default in the performance of any
obligation, agreement, covenant or condition contained in any indenture, loan
agreement, mortgage, lease or other agreement or instrument to which either
Issuer or any of their subsidiaries is a party or by which either Issuer 

                                       11
<PAGE>   13


or any of their subsidiaries or their respective property is bound, except for
such defaults which, singly or in the aggregate, would not have a Material
Adverse Effect.

         (p) The execution, delivery and performance by each Issuer of each of
the Operative Documents to which it is a party, the compliance by each Issuer
with all provisions thereof and the consummation of the transactions
contemplated thereby, and the consummation of the Offer to Purchase (as defined
in the Offering Memorandum) will not (i) require any consent, approval,
authorization or other order of, or qualification with, any court or
governmental body or agency (except such as may be required under the federal
securities or Blue Sky laws of the various states or have been or will be
obtained prior to the Closing Date), (ii) conflict with or constitute a breach
of any of the terms or provisions of, or a default under, (A) the organizational
documents of the Issuers or any of their subsidiaries or (B), except as
otherwise set forth in the Offering Memorandum, any indenture, loan agreement,
mortgage, lease or other agreement or instrument that is material to Holdings
and its subsidiaries, taken as a whole, to which either Issuer or any of their
subsidiaries is a party or by which either Issuer or any of their subsidiaries
or their respective property is bound, (iii) violate or conflict with any
applicable law or any rule, regulation, judgment, order or decree of any court
or any governmental body or agency having jurisdiction over either Issuer or any
of their subsidiaries or their respective property, (iv) except as otherwise set
forth in the Offering Memorandum, result in the imposition or creation of (or
the obligation to create or impose) a Lien under any agreement or instrument to
which either Issuer or any of their subsidiaries is a party or by which either
Issuer or any of their subsidiaries or their respective property is bound, or
(v) result in the termination, suspension or revocation of any Authorization (as
defined below) of either Issuer or any of their subsidiaries or result in any
other impairment of the rights of the holder of any such Authorization, except,
in the case of clauses (i), (ii)(B), (iv) and (v), as would not, singly or in
the aggregate, have a Material Adverse Effect.

         (q) To the best knowledge of each Issuer, no action has been taken and
no law, statute, rule or regulation or order has been enacted, adopted or issued
by any governmental agency or body which prevents the execution, delivery and
performance of any of this Agreement, the Indenture, the Notes, the Warrants,
the Warrant Agreement or any of the other Operative Documents or the issuance of
the Securities, or suspends the sale of the Securities in any jurisdiction
referred to in Section 5(e) and no injunction, restraining order or other order
or relief of any nature by a federal or state court or other tribunal of
competent jurisdiction has been issued with respect to either Issuer which would
prevent or suspend the issuance or sale of the Units in any jurisdiction
referred to in Section 5(e).

         (r) There are no legal or governmental proceedings pending or
threatened to which either Issuer or any of their subsidiaries is or could be a
party or to which any of their respective property is or could be subject, which
might result, singly or in the aggregate, in a Material Adverse Effect.

         (s) To the best knowledge of each Issuer, neither Issuer nor any of
their subsidiaries has violated any foreign, federal, state or local law or
regulation relating to the protection of human health and safety, the
environment or hazardous or toxic substances or wastes, pollutants or
contaminants ("Environmental Laws"), any provisions of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), or any provisions of the
Foreign Corrupt Practices

                                       12
<PAGE>   14

Act or the rules and regulations promulgated thereunder, except for such
violations which, singly or in the aggregate, would not have a Material Adverse
Effect.

         (t) There are no known costs or liabilities associated with
Environmental Laws (including, without limitation, any capital or operating
expenditures required for clean-up, closure of properties or compliance with
Environmental Laws or any Authorization, any related constraints on operating
activities and any potential liabilities to third parties) which would, singly
or in the aggregate, have a material adverse effect on the business, financial
condition or results of operations of Holdings and its subsidiaries, taken as a
whole.

         (u) Each of the Issuers and their subsidiaries has such permits,
licenses, consents, exemptions, franchises, authorizations and other approvals
(each, an "Authorization") of, and has made all filings with and notices to,
all governmental or regulatory authorities and self-regulatory organizations and
all courts and other tribunals, including without limitation, under any
applicable Environmental Laws, as are necessary to own, lease, license and
operate its respective properties and to conduct its business, except where the
failure to have any such Authorization or to make any such filing or notice
would not, singly or in the aggregate, have a Material Adverse Effect. Each such
Authorization is valid and in full force and effect and each of the Issuers and
their subsidiaries is in compliance with all the terms and conditions thereof
and with the rules and regulations of the authorities and governing bodies
having jurisdiction with respect thereto; and no event has occurred (including,
without limitation, the receipt of any notice from any authority or governing
body) which allows or, after notice or lapse of time or both, would allow,
revocation, suspension or termination of any such Authorization or results or,
after notice or lapse of time or both, would result in any other impairment of
the rights of the holder of any such Authorization; and such Authorizations
contain no restrictions that are burdensome to either Issuer or any of their
subsidiaries; except, in each case, where such failure to be valid and in full
force and effect or to be in compliance, the occurrence of any such event or the
presence of any such restriction, would not, singly or in the aggregate, have a
Material Adverse Effect.

         (v) The accountants, KPMG Peat Marwick LLP, that have certified the
financial statements included in the Preliminary Offering Memorandum and the
Offering Memorandum are independent public accountants with respect to each
Issuer, as required by the Securities Act and the Exchange Act.

         (w) The historical financial statements, together with related notes,
forming part of the Preliminary Offering Memorandum and the Offering Memorandum
(and any amendment or supplement thereto), present fairly the consolidated
financial position, results of operations and changes in financial position of
Insilco and its subsidiaries (and for the third quarter of 1998 Holdings and its
subsidiaries as set forth in Annex A to the Offering Memorandum) on the basis
stated in the Preliminary Offering Memorandum and the Offering Memorandum at the
respective dates or for the respective periods to which they apply; such
statements and related schedules and notes have been prepared in accordance with
generally accepted accounting principles consistently applied throughout the
periods involved, except as disclosed therein; and the other financial and
statistical information and data set forth in the Preliminary Offering
Memorandum and the Offering Memorandum (and any amendment or supplement thereto)
are, in all material respects, accurately presented and prepared on a basis
consistent with such 

                                       13
<PAGE>   15



financial statements and the books and records of Insilco and its subsidiaries
or Holdings and its subsidiaries, as the case may be.

         (x) To the best knowledge of each Issuer, each Issuer has complied with
all provisions of Section 517.075, Florida Statues (Chapter 92-198, Laws of
Florida).

         (y) The pro forma financial statements included in the Preliminary
Offering Memorandum and the Offering Memorandum have been prepared on a basis
consistent with the historical financial statements of Insilco and its
subsidiaries and give effect to assumptions used in the preparation thereof on a
reasonable basis and in good faith and present fairly the historical and
proposed transactions contemplated by the Preliminary Offering Memorandum and
the Offering Memorandum; and such pro forma financial statements comply as to
form in all material respects with the requirements applicable to pro forma
financial statements included in registration statements on Form S-1 under the
Securities Act. The other pro forma financial and statistical information and
data included in the Preliminary Offering Memorandum and the Offering Memorandum
are, in all material respects, accurately presented and prepared on a basis
consistent with the pro forma financial statements.

         (z) Neither Issuer is, and after giving effect to the offering and sale
of the Units and the application of the net proceeds thereof as described in the
Offering Memorandum, neither Issuer will be, an "investment company," as such
term is defined in the Investment Company Act of 1940, as amended.

         (aa) Except as otherwise set forth in the Offering Memorandum, there
are no contracts, agreements or understandings between either Issuer and any
person granting such person the right to require such Issuer to file a
registration statement under the Securities Act with respect to any securities
of the Issuer or to require such Issuer to include such securities with the
Securities registered pursuant to any Registration Statements.

         (bb) Neither Issuer nor any agent thereof acting on its behalf has
taken, and none of them will take, any action that might cause this Agreement or
the issuance or sale of the Series A Notes to violate Regulation G (12 C.F.R.
Part 207), Regulation T (12 C.F.R. Part 220), Regulation U (12 C.F.R. Part 221)
or Regulation X (12 C.F.R. Part 224) of the Board of Governors of the Federal
Reserve System.

         (cc) No "nationally recognized statistical rating organization" (as
such term is defined for purposes of Rule 436(g)(2) under the Securities Act)
(i) has imposed (or has informed either Issuer that it is considering imposing)
any condition (financial or otherwise) on such Issuer's retaining any rating
assigned to such Issuer or any securities of such Issuer or (ii) has indicated
to such Issuer that it is considering (A) the downgrading, suspension, or
withdrawal of, or any review for a possible change that does not indicate the
direction of the possible change in, any rating so assigned or (B) any change in
the outlook for any rating of such Issuer, or any securities of such Issuer.

         (dd) Since the respective dates as of which information is given in the
Offering Memorandum other than as set forth in the Offering Memorandum
(exclusive of any amendments or supplements thereto subsequent to the date of
this Agreement), (i) there has not occurred any material adverse change or any
development involving a prospective material adverse change in the condition,
financial or otherwise, or the earnings, business, management

                                       14
<PAGE>   16

or operations of Holdings and its subsidiaries, taken as a whole, (ii) there has
not been any material adverse change or any development involving a prospective
material adverse change in the capital stock or in the long-term debt of
Holdings or any of its subsidiaries and (iii) neither Holdings nor any of its
subsidiaries has incurred any material liability or obligation, direct or
contingent.

         (ee) Each of the Preliminary Offering Memorandum and the Offering
Memorandum, as of its date, contains all the information specified in, and
meeting the requirements of, Rule 144A(d)(4) under the Securities Act.

         (ff) When the Series A Notes and Warrants are issued and delivered
pursuant to this Agreement, neither the Series A Notes nor the Warrants will be
of the same class (within the meaning of Rule 144A under the Securities Act) as
any security of Holdings or Insilco that is listed on a national securities
exchange registered under Section 6 of the Exchange Act or that is quoted in a
United States automated inter-dealer quotation system.

         (gg) No form of general solicitation or general advertising (as defined
in Regulation D under the Securities Act) was used by either Issuer or any of
its representatives (other than the Initial Purchaser, as to whom the Issuers
make no representation) in connection with the offer and sale of the Units
contemplated hereby, including, but not limited to, articles, notices or other
communications published in any newspaper, magazine, or similar medium or
broadcast over television or radio, or any seminar or meeting whose attendees
have been invited by any general solicitation or general advertising. No
securities of the same class as the Series A Notes or the Warrants have been
issued and sold by Insilco or Holdings within the six-month period immediately
prior to the date hereof.

         (hh) Prior to the effectiveness of any Registration Statement, the
Indenture is not required to be qualified under the TIA.

         (ii) No registration under the Securities Act of the Units, the
Warrants or the Series A Notes is required for the sale of such securities to
the Initial Purchaser as contemplated hereby or for the Exempt Resales assuming
the accuracy of the Initial Purchaser's representations and warranties and
agreements set forth in Section 7 hereof.

         (jj) There is no (i) material unfair labor practice complaint,
grievance or arbitration proceeding pending or, to the best knowledge of each
Issuer, threatened against either Issuer or any of their subsidiaries before the
National Labor Relations Board or any state or local labor relations board or
(ii) strike, labor dispute, slowdown or stoppage pending or, to the best
knowledge of each Issuer, threatened against either Issuer or any of their
subsidiaries, except for such actions specified in clause (i) or (ii) above,
which, singly or in the aggregate, would not have a Material Adverse Effect. To
the best of each Issuer's knowledge, no collective bargaining organizing
activities are taking place with respect to either Issuer or any of their
subsidiaries, which, singly or in the aggregate, would have a Material Adverse
Effect.

         (kk) Each of the Issuers and their subsidiaries maintain a system of
internal accounting controls sufficient to provide reasonable assurance that (i)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain asset accountability, and (ii) the recorded accountability 

                                       15
<PAGE>   17


for assets is compared with the existing assets at reasonable intervals and
appropriate action is taken with respect to any differences.

         (ll) Except as otherwise set forth in the Offering Memorandum, the
Issuers and their subsidiaries own or possess, or can acquire on reasonable
terms, all patents, patent rights, licenses, inventions, copyrights, know-how
(including trade secrets and other unpatented and/or unpatentable proprietary or
confidential information, systems or procedures), trademarks, service marks and
trade names ("intellectual property") currently employed by them in connection
with the business now operated by them except where the failure to own or
possess or otherwise be able to acquire such intellectual property would not,
singly or in the aggregate, have a Material Adverse Effect; and, to the best of
each Issuer's knowledge, neither of the Issuers nor any of their subsidiaries
has received any notice of infringement of or conflict with asserted rights of
others with respect to any of such intellectual property which, singly or in the
aggregate, if the subject of an unfavorable decision, ruling or finding, would
have a Material Adverse Effect.

         (mm) Each certificate signed by any officer of either Issuer and
delivered to the Initial Purchaser or counsel for the Initial Purchaser shall be
deemed to be a representation and warranty by such Issuer to the Initial
Purchaser as to the matters covered thereby.

         Each Issuer acknowledges that the Initial Purchaser and, for purposes
of the opinions to be delivered to the Initial Purchaser pursuant to Section 9
hereof, counsel to the Issuer and counsel to the Initial Purchaser will rely
upon the accuracy and truth of the foregoing representations and hereby consents
to such reliance.

         7. INITIAL PURCHASER'S REPRESENTATIONS AND WARRANTIES. The Initial
Purchaser represents and warrants to, and agrees with, the Issuers:

         (a) The Initial Purchaser is either a QIB or an institutional
"accredited investor" (as such term is defined in Rule 501(a)(1), (2), (3) or
(7) under the Securities Act, an "Accredited Institution"), in either case,
with such knowledge and experience in financial and business matters as is
necessary in order to evaluate the merits and risks of an investment in the
Units.

         (b) The Initial Purchaser is not acquiring the Units with a view to any
distribution thereof or with any present intention of offering or selling any of
the Units in a transaction that would violate the Securities Act or the
securities laws of any state of the United States or any other applicable
jurisdiction. The Initial Purchaser will be reoffering and reselling the Units
only to QIBs in reliance on the exemption from the registration requirements of
the Securities Act provided by Rule 144A.

         (c) The Initial Purchaser agrees that no form of general solicitation
or general advertising (within the meaning of Regulation D under the Securities
Act) has been or will be used by the Initial Purchaser or any of its
representatives in connection with the offer and sale of the Units pursuant
hereto, including, but not limited to, articles, notices or other communications
published in any newspaper, magazine or similar medium or broadcast over
television or radio, or any seminar or meeting whose attendees have been invited
by any general solicitation or general advertising.

                                       16
<PAGE>   18


         (d) The Initial Purchaser agrees that, in connection with Exempt
Resales, the Initial Purchaser will solicit offers to buy the Units only from,
and will offer to sell the Units only to, Eligible Purchasers. The Initial
Purchaser further agrees that it will offer to sell the Units only to, and will
solicit offers to buy the Units only from Eligible Purchasers that the Initial
Purchaser reasonably believes are QIBs that agree that (x) the Units purchased
by them may be resold, pledged or otherwise transferred within the time period
referred to under Rule 144(k) (taking into account the provisions of Rule 144(d)
under the Securities Act, if applicable) under the Securities Act, as in effect
on the date of the transfer of such Units, only (I) to the Issuers or any of
their subsidiaries, (II) to a person whom the seller reasonably believes is a
QIB purchasing for its own account or for the account of a QIB in a transaction
meeting the requirements of Rule 144A under the Securities Act, (III) in a
transaction meeting the requirements of Rule 144 under the Securities Act, (IV)
to an Accredited Institution that, prior to such transfer (A) in the case of the
Series A Notes, furnishes the Trustee a signed letter containing certain
representations and agreements relating to the registration of transfer of such
Series A Notes (the form of which may be obtained from the Trustee) or (B) in
the case of the Warrants, furnishes the Warrant Agent a signed letter containing
certain representations and agreements relating to the registration of transfer
of such Warrants (the form of which may be obtained from the Warrant Agent),
and, with respect to the Series A Notes, if such transfer is in respect of an
aggregate principal amount of Series A Notes less than $250,000, and, with
respect to the Warrants, an opinion of counsel acceptable to the Issuers that
such transfer is in compliance with the Securities Act, (V) in accordance with
another exemption from the registration requirements of the Securities Act (and
based upon an opinion of counsel acceptable to the Issuer thereof) or (VI)
pursuant to an effective registration statement and, in each case, in accordance
with the applicable securities laws of any State of the United States or any
other applicable jurisdiction and (y) they will deliver to each person to whom
such Units or an interest therein is transferred a notice substantially to the
effect of the foregoing.

         The Initial Purchaser acknowledges that the Issuers and, for purposes
of the opinions to be delivered to the Initial Purchaser pursuant to Section 9
hereof, counsel to the Issuers and counsel to the Initial Purchaser will rely
upon the accuracy and truth of the foregoing representations, and the Initial
Purchaser hereby consents to such reliance.

         8.       INDEMNIFICATION.

         (a) The Issuers, jointly and severally, agree to indemnify and hold
harmless the Initial Purchaser, its directors, its officers and each person, if
any, who controls the Initial Purchaser within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages, liabilities and judgments (including, without
limitation, any legal or other expenses incurred in connection with
investigating or defending any matter, including any action, that could give
rise to any such losses, claims, damages, liabilities or judgments) caused by
any untrue statement or alleged untrue statement of a material fact contained in
the Offering Memorandum (or any amendment or supplement thereto), the
Preliminary Offering Memorandum or any Rule 144A Information provided by the
Issuers to any holder or prospective purchaser of Units pursuant to Section 5(h)
or caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities or
judgments are caused by any such untrue statement or omission or 

                                       17

<PAGE>   19

alleged untrue statement or omission based upon information relating to the
Initial Purchaser furnished in writing to the Issuers by the Initial Purchaser;
provided, however, that the foregoing indemnity agreement with respect to any
Preliminary Offering Memorandum shall not inure to the benefit of the Initial
Purchaser if the Initial Purchaser fails to deliver a final Offering Memorandum
(as then amended or supplemented, provided by the Issuers to the Initial
Purchaser in the requisite quantity and on a timely basis to permit proper
delivery on or prior to the Closing Date) to the person asserting any losses,
claims, damages and liabilities and judgments caused by any untrue statement or
alleged untrue statement of a material fact contained in any Preliminary
Offering Memorandum, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, if such material misstatement or omission or
alleged material misstatement or omission was cured in the final Offering
Memorandum.

         (b) The Initial Purchaser agrees to indemnify and hold harmless each
Issuer and its directors and officers and each person, if any, who controls
(within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act) such Issuer to the same extent as the foregoing indemnity from the
Issuers to the Initial Purchaser but only with reference to information relating
to the Initial Purchaser furnished in writing to the Issuers by the Initial
Purchaser expressly for use in the Preliminary Offering Memorandum or the
Offering Memorandum.

         (c) In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"Indemnified Party"), the Indemnified Party shall promptly notify the person
against whom such indemnity may be sought (the "Indemnifying Party") in
writing and the Indemnifying Party shall assume the defense of such action,
including the employment of counsel reasonably satisfactory to the Indemnified
Party and the payment of all fees and expenses of such counsel, as incurred
(except that, in the case of any action in respect of which indemnity may be
sought pursuant to both Sections 8(a) and 8(b), the Initial Purchaser shall not
be required to assume the defense of such action pursuant to this Section 8(c),
but may employ separate counsel and participate in the defense thereof, but the
fees and expenses of such counsel, except as provided below, shall be at the
expense of the Initial Purchaser). Any Indemnified Party shall have the right to
employ separate counsel in any such action and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party unless (i) the employment of such counsel shall have been
specifically authorized in writing by the Indemnifying Party, (ii) the
Indemnifying Party shall have failed to assume the defense of such action or
employ counsel reasonably satisfactory to the Indemnified Party or (iii) the
named parties to any such action (including any impleaded parties) include both
the Indemnified Party and the Indemnifying Party, and the Indemnified Party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the Indemnifying Party (in which case the Indemnifying Party shall
not have the right to assume the defense of such action on behalf of the
Indemnified Party). In any such case, the Indemnifying Party shall not, in
connection with any one action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) for all Indemnified Parties
and all such fees and expenses shall be reimbursed as they are incurred. Such
firm shall be designated 

                                       18
<PAGE>   20


in writing by Donaldson, Lufkin & Jenrette Securities Corporation, in the case
of the parties indemnified pursuant to Section 8(a), and by the Issuers, in the
case of parties indemnified pursuant to Section 8(b). The Indemnifying Party
shall indemnify and hold harmless the Indemnified Party from and against any and
all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
business days after the Indemnifying Party shall have received a request from
the Indemnified Party for reimbursement for the fees and expenses of counsel (in
any case where such fees and expenses are at the expense of the Indemnifying
Party) and, prior to the date of such settlement, the Indemnifying Party shall
have failed to comply with such reimbursement request. No Indemnifying Party
shall, without the prior written consent of the Indemnified Party, effect any
settlement or compromise of, or consent to the entry of judgment with respect
to, any pending or threatened action in respect of which the Indemnified Party
is or could have been a party and indemnity or contribution may be or could have
been sought hereunder by the Indemnified Party, unless such settlement,
compromise or judgment (i) includes an unconditional release of the Indemnified
Party from all liability on claims that are or could have been the subject
matter of such action and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of the
Indemnified Party.

         (d) To the extent the indemnification provided for in this Section 8 is
unavailable to an Indemnified Party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Issuers, on the one hand, and the Initial Purchaser, on the other hand, from the
offering of the Units or (ii) if the allocation provided by clause 8(d)(i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause 8(d)(i) above but
also the relative fault of the Issuers, on the one hand, and the Initial
Purchaser, on the other hand, in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or judgments, as
well as any other relevant equitable considerations. The relative benefits
received by the Issuers, on the one hand, and the Initial Purchaser, on the
other hand, shall be deemed to be in the same proportion as the total net
proceeds from the offering of the Units (after underwriting discounts and
commissions, but before deducting expenses) received by the Issuers, and the
total discounts and commissions received by the Initial Purchaser bear to the
total price to investors of the Units, in each case, as set forth in the table
on the cover page of the Offering Memorandum. The relative fault of the Issuers,
on the one hand, and the Initial Purchaser, on the other hand, shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Issuers, on the one hand,
or the Initial Purchaser, on the other hand, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

         The Issuers and the Initial Purchaser agree that it would not be just
and equitable if contribution pursuant to this Section 8(d) were determined by
pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified 

                                       19

         (a) All the representations and warranties of the Issuers contained in
this Agreement shall be true and correct on the Closing Date with the same force
and effect as if made on and as of the Closing Date.

downgrading, suspension or withdrawal of, nor shall any notice have been given
of any potential or intended downgrading, suspension or withdrawal of, or of any
review (or of any potential or intended review) for a possible change that does
not indicate the direction of the possible change in, any rating of either
Issuer or any securities of either Issuer (including, without limitation, the

Offering Memorandum other than as set forth in the Offering Memorandum
(exclusive of any amendments or supplements thereto subsequent to the date of

which, in any such case described in clause 9(c)(i), 9(c)(ii) or 9(c)(iii), in
the judgment of the Initial Purchaser, is material and adverse and, in the
judgment of the Initial Purchaser, makes it impracticable to market the Units on
the terms and in the manner contemplated in the Offering Memorandum.

         (d) You shall have received on the Closing Date a certificate dated the
Closing Date, signed by the President and the Chief Financial Officer of each
Issuer, confirming the matters set forth in Sections 6(cc), 9(a), 9(b) and 9(c)

         (e) The Initial Purchaser shall have received on the Closing Date an
opinion (satisfactory to the Initial Purchaser and counsel for the Initial
Purchaser), dated the Closing Date, of Kenneth H. Koch, General Counsel for the
Issuers, to the effect that:

                  (i) each Issuer has been duly incorporated and is validly
         existing in good standing under the laws of its jurisdiction of
         organization and has the requisite power to enter into the Operative
         Documents to which it is a party;

                     (ii) all the outstanding shares of capital stock of Insilco
         are duly authorized and validly issued and are fully paid and
         non-assessable and have not been issued in violation of any preemptive
         rights pursuant to law or Insilco's certificate of incorporation;

                    (iii) all the shares of capital stock of Holdings
         outstanding prior to the Mergers and the Merger Financing (as such
         terms are defined in the Offering Memorandum), and any shares of
         capital stock of Holdings issued subsequent to the Mergers and prior to
         the date hereof, are duly authorized and validly issued and, to such
         counsel's knowledge, fully paid and non-assessable and have not been
         issued in violation of any preemptive rights pursuant to law or
         Holding's certificate of incorporation;

                  (iv) each Significant Subsidiary is a corporation duly

         being conducted. Each Issuer and each Significant Subsidiary is a
         corporation duly qualified to transact business and is in good standing
         as a foreign corporation in each jurisdiction where the character of
         its activities requires such qualification, except where the failure to
         be so qualified would not have a Material Adverse Effect;

                      (v) all of the outstanding shares of the capital stock of
         each Significant Subsidiary are duly authorized, validly issued, and,
         to such counsel's knowledge, fully paid and nonassessable, and have not
         been issued in violation of any preemptive rights pursuant to law or in
         such certificate of incorporation of such Significant Subsidiary, and
         all of the outstanding shares of the capital stock of each Significant
         Subsidiary are owned by Insilco, however, as set forth in the Offering
         Memorandum, all of such shares have been pledged to Insilco's lenders
         under the Existing Credit Facility (as such term is defined in the
         Offering Memorandum) and are expected to be pledged to Insilco's



                                       21

         Credit Facility, with respect to the pledge of Insilco stock, and such
         other registration rights agreements as are described in the Offering
         Memorandum) granting any person the right to require either Issuer to
         file a registration statement under the Securities Act with respect to
         any securities of the Issuers or to require either Issuer to include
         such securities with the Securities registered pursuant to any
         Registration Statement; and

                    (vii) the execution, delivery and performance by the Issuers
         of the Operative Documents to which each is a party, the consummation
         of the transactions contemplated thereby and compliance by the Issuers
         with the provisions thereof, and the consummation of the Offer to
         Purchase, will not (i) except to the extent such has been obtained,
         require any consent, approval, authorization or other order of, or
         qualification with, any court or governmental body or agency (except
         such as may be required under the Securities Act or the securities or
         Blue Sky laws of the various states or by NASD or the Secretary of
         State of Delaware), (ii) conflict with or constitute a breach of any of
         the terms or provisions of, or a default under, (A) the certificate of
         incorporation or bylaws of Insilco or Holdings, as the case may be, or
         (B), assuming receipt of the consents from the lenders under the
         Existing Credit Facility as described in the Offering Memorandum,

         of parties to, or conflict with or constitute a breach of any of the
         terms or provisions of, or a default under, any document, agreement or
         other instrument to which Holdings or any of its subsidiaries is a
         party or by which any of them is bound, (iii) to such counsel's
         knowledge, violate or conflict with any statute or any order, rule or

         respective properties, or (iv) result in the termination, suspension or
         revocation of any Authorization of Holdings or any of its subsidiaries,
         except in the case of clauses (i), (ii)(B), (iii) and (iv), as would

rendered to the Initial Purchaser at the request of the Issuers and shall so
state therein.

force and effect, and will survive delivery of and payment for the Units,
regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of the Initial Purchaser, the officers or directors of the
Initial Purchaser, any person controlling the Initial Purchaser, the Issuers,
the officers or directors of the Issuers, or any person controlling the Issuer,
(ii) acceptance of the Units and payment for them hereunder and (iii)
termination of this Agreement.


         If for any reason the Units are not delivered by or on behalf of the
Issuers as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 10), Insilco agrees to reimburse the Initial
Purchaser for all out-of-pocket expenses (including the fees and disbursements
of counsel) incurred by them. Notwithstanding any termination of this Agreement,
Insilco shall be liable for all expenses which the Issuers have agreed to pay
pursuant to Section 5(i) hereof. Insilco also agrees to reimburse the Initial
Purchaser and its officers, directors and each person, if any, who controls the
Initial Purchaser within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act for any and all fees and expenses (including
without limitation the fees and expenses of counsel) incurred by them in
connection with enforcing their rights under this Agreement (including without
limitation their rights under Section 8).
