                        Registrant and First Union National Bank, as trustee

         Exhibit 4.2    Registration Rights Agreement dated November 26, 1996

         Exhibit 4.5    Form of Regulation S Global Note 

ITEM 9. SALES OF EQUITY SECURITIES PURSUANT TO REGULATION S

        Pursuant to a purchase agreement (the "Purchase Agreement") dated
November 20, 1996, between the Registrant and the initial purchasers, on
November 26, 1996, the Registrant sold $74,750,000 ($65,000,000 plus $9,750,000
pursuant to the exercise of the over-allotment option granted to the initial
purchasers) aggregate principal amount of its 6-1/4% Convertible Subordinated
Notes due 2003 (the "Notes") to the initial purchasers at an initial offering
price of 100% of the principal amount thereof, less 3% gross commission.

        The initial purchasers advised the Registrant that the Notes were to
be resold at 100% of the principal amount thereof (i) to qualified institutional
buyers in reliance on Rule 144A under the Securities Act of 1933, as amended
(the "Act") and to institutional "accredited investors" within the meaning of
Rule 501(a)(1), (2), (3) or (7) under the Act, that agreed in writing to comply
with the transfer restrictions and other conditions set forth in the Purchase
Agreement and (ii) outside the United States to certain persons in reliance on
Regulation S under the Act.  The initial purchasers advised the Registrant that
$1,750,000 aggregate principal amount of Notes were sold outside the United
States to certain persons in reliance on Regulations S under the Act.

        In connection with sales of the Notes outside the United States, each
initial purchaser agreed that, except for sales described above, it would not
offer, sell or deliver the Notes to, or for the account or benefit of, U.S.
persons (as 

                                2

<PAGE>

defined in Regulation S under the Act) (i) as part of such initial 
purchaser's distribution at any time or (ii) otherwise until 40 days after 
the later of the commencement of the offering of the Notes and the last 
closing date with respect to the Notes, and that it would send to each dealer 
to whom it sold such Notes during such period a confirmation or other notice 
setting forth the restrictions on offers and sales of the Notes within the 
United States or to, or for the account or benefit of, U.S. persons.  

        The Notes were issued under an Indenture, dated as of November 26, 
1996 (the "Indenture"), between the Registrant and First Union National Bank, 
as trustee.  The Notes represent general unsecured subordinated obligations 
of the Registrant.  The Notes are convertible into shares of the Registrant's 
Common Stock, par value $.10 per share (the "Common Stock"), at the option of 
the holder thereof, at any time after February 24, 1997 until the close of 
business on November 28, 2003, subject to prior redemption or repurchase, at 
an initial conversion price of $28.44 per share.   The conversion price is 
subject to adjustment (under formulae set forth in the Indenture) upon the 
occurrence of certain events, including, but not limited to: (i) the issuance 
of Common Stock as a dividend or distribution on the outstanding Common 
Stock; (ii) the issuance to all holders of Common Stock of certain rights, 
options or warrants to purchase Common Stock at less than the Current Market 
Price (as defined in the Indenture); (iii) certain subdivisions, combinations 
and reclassifications of Common Stock; (iv) certain defined distributions to 
all holders of Common Stock of any class of capital stock of the Registrant; 
(v) certain cash distributions; and (vi) the purchase of Common Stock 
pursuant to a tender offer made by the Registrant or any of its subsidiaries 
in certain defined circumstances.  

         The Registrant currently does not have a sufficient number of shares
of Common Stock available for issuance upon conversion of all of the Notes and
the exercise of all outstanding options granted by the Registrant pursuant to
the Registrant's Employee Incentive Stock Option Plan and Agent Stock Option
Plan.  In order to provide a sufficient number of shares of Common Stock to
permit the conversion of all Notes, the Registrant has agreed as soon as
practicable to seek and recommend the approval of its shareholders to amend its
articles of incorporation to increase the number of authorized shares of Common
Stock to an amount at least sufficient to permit the conversion of all Notes. 
In the event a holder of Notes desires to convert all, or any portion, of its
Notes into shares of Common Stock at a time when the Registrant does not have a
sufficient number of shares of Common Stock available for such conversion, in
lieu of delivering shares of Common Stock upon conversion of that portion of
such holder's Notes for which there 

                                  3

<PAGE>

is an insufficient number of shares of Common Stock (the "Cash Equivalent 
Notes"), the Registrant will pay to the holder converting the Cash Equivalent 
Notes an amount in cash equal to the Market Price of the shares of Common 
Stock into which the Cash Equivalent Notes are then convertible.  "Market 
Price" means the average of the last reported closing prices of the Common 
Stock for the ten trading day period (appropriately adjusted to take into 
account the occurrence during such period of certain events that would result 
in an adjustment of the conversion price), commencing on the first trading 
day after delivery of notice to such holder that the Registrant must pay cash 
in lieu of delivering shares of Common Stock.

Dear Sirs:

         Penn Treaty American Corporation, a Pennsylvania corporation (the
"COMPANY"), proposes, subject to the terms and conditions stated herein, to
issue and sell to the several Initial Purchasers named in Schedule I hereto (the
"INITIAL PURCHASERS") an aggregate of $65,000,000 principal amount of its 6-1/4%
Convertible Subordinated Notes due 2003 (the "FIRM NOTES").  In addition, the
Company proposes to grant to the Initial Purchasers an option, for the sole
purpose of covering over allotments in connection with the sale of the Firm
Notes, to purchase up to an additional $9,750,000 principal amount of Notes (the
"OPTIONAL NOTES") as provided in Section 2 below.  The Firm Notes and any
Optional Notes purchased by the Initial Purchasers are referred to herein as the
"NOTES".

         The Notes are to be issued pursuant to an indenture to be dated as of
November 26, 1996 (the "INDENTURE") between the Company and First Union National
Bank, as trustee (the "TRUSTEE"), and, except as otherwise provided therein and
in the Indenture, will be convertible into shares of the Company's common stock,
par value $.10 per share (the "COMMON STOCK"), on the terms set forth therein.
The holders of the Notes will be entitled to certain registration rights
provided under a Registration Rights Agreement to be dated November 26, 1996
(the "REGISTRATION RIGHTS AGREEMENT") between the Company and the Initial
Purchasers.

<PAGE>

         The Company has prepared a preliminary offering circular dated
November 8, 1996 (the "PRELIMINARY OFFERING CIRCULAR") and a final offering
circular dated November 20, 1996 (as supplemented from time to time with the
written consent of the Company and Bear, Stearns & Co. Inc. (as the
representative of the Initial Purchasers, the "REPRESENTATIVE") (the "OFFERING
CIRCULAR") with respect to the offering of the Notes contemplated by this
Agreement (the "OFFERING").  The terms "Preliminary Offering Circular" and
"Offering Circular" as used herein shall include all documents incorporated by
reference therein.

         The Notes have not been registered under the Securities Act of 1933,
as amended (the "SECURITIES ACT"), and are being offered and sold in reliance on
exemptions from or in transactions not subject to the registration requirements
of the Securities Act, including sales (i) made in the United States to
"qualified institutional buyers" as defined in, and in reliance on, Rule 144A
under the Securities Act ("RULE 144A") or to institutional "accredited
investors" as defined in Rule 501(a)(1),(2), (3) and (7) of Regulation D under
the Securities Act ("REGULATION D") and (ii) made outside the United States in
reliance on Regulation S under the Securities Act ("REGULATION S").

         1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company
represents and warrants to, and agrees with, the Initial Purchasers that:

         (a)  The Offering Circular, as of the date hereof, and as of the
Closing Date (as hereinafter defined) and as of the Additional Closing Date (as
hereinafter defined), if any, is and will be accurate in all material respects,
does not and will not contain an untrue statement of a material fact and does
not and will not omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.  No representation and
warranty is made in this Section 1(a), however, with respect to any information
contained in or omitted from the Offering Circular or any amendment thereof or
supplement thereto in reliance upon and in conformity with information furnished
in writing to the Company by either Initial Purchaser expressly for use in
connection with the preparation of the Offering Circular or any amendment
thereof or supplement thereto, as the case may be.

         (b)  Coopers & Lybrand L.L.P., who have certified certain of the
financial statements and supporting schedules included or incorporated by
reference in the Offering Circular, are independent public accountants as
required by the Securities Act and the rules and regulations promulgated
thereunder (the "REGULATIONS").

                                       2

<PAGE>

         (c)  The financial statements, including the notes thereto, and
supporting schedules, included or incorporated by reference in the Offering
Circular present fairly the consolidated financial position of the Company and
its subsidiaries as of the dates indicated and the consolidated results of
operations and changes in financial position of the Company and its subsidiaries
for the periods specified; except as otherwise stated in the Offering Circular,
such financial statements have been prepared in conformity with generally
accepted accounting principles applied on a consistent basis; and the supporting
schedules included or incorporated by reference in the Offering Circular present
fairly the information required to be stated therein.  The pro forma financial
statements and other pro forma financial information included in the Offering
Circular have been prepared in all material respects in accordance with the
rules and regulations of the Securities and Exchange Commission (the
"COMMISSION") with respect to pro forma financial statements, have been properly
compiled on the pro forma bases described therein, and, in the opinion of the
Company, the assumptions used in the preparation thereof are reasonable and the
adjustments used therein are appropriate to give effect to the transactions or
circumstances referred to therein.

         (d)  Other than Penn Treaty Life Insurance Company, Network America
Life Insurance Company, American Network Insurance Company and Senior Financial
Consultants Company (each, a "SIGNIFICANT SUBSIDIARY" and together, the
"SIGNIFICANT SUBSIDIARIES"), the Company does not own or control, directly or
indirectly, any corporation, association or other entity that would constitute a
"significant subsidiary" within the meaning of Rule 1-02(w) of Regulation S-X
under the Securities Act.

         (e)  Subsequent to the respective dates as of which information is
given in the Offering Circular, except as set forth in the Offering Circular,
there has been no material adverse change in the business, properties,
operations, condition (financial or otherwise) or results of operations of the
Company and its subsidiaries taken as a whole, whether or not arising from
transactions in the ordinary course of business, and since the date of the
latest balance sheet presented in the Offering Circular, neither the Company nor
any of the Significant Subsidiaries has incurred or undertaken any liabilities
or obligations, direct or contingent, that are material to the Company and its
subsidiaries taken as a whole, except for liabilities or obligations that are
disclosed in the Offering Circular.

         (f)  Each of the Company and the Significant Subsidiaries (i) has been
duly incorporated and is validly subsisting under the laws of its jurisdiction
of incorporation, (ii) is duly qualified and in good standing as a foreign
corporation in each jurisdiction in which the character or location of its
properties (owned, leased or 

                                       3

<PAGE>

licensed) or the nature or conduct of its business makes such qualification 
necessary, except for those failures to be so qualified or in good standing 
that will not in the aggregate have a material adverse effect on the Company 
and its subsidiaries taken as a whole, and (iii) has all requisite power and 
authority, and all necessary consents, approvals, authorizations, orders, 
registrations, qualifications, licenses and permits of and from all public, 
regulatory or governmental agencies and bodies (including without limitation 
all licenses from the insurance departments of the various states in which 
subsidiaries of the Company write business), to own, lease and operate its 
properties and conduct its business as now being conducted and as described 
in the Offering Circular.  Each subsidiary of the Company engaged in 
underwriting insurance has fulfilled and performed all of its material 
obligations under, and is in compliance with all material requirements and 
conditions of, all licenses from the insurance departments of the various 
states in which it currently underwrites insurance and no event has occurred 
that allows or, after notice or lapse of time, would allow or result in the 
revocation or termination of, or any material impairment of the rights and 
privileges of such subsidiary under, any such license.

         (g)  The Company has all requisite corporate power and authority to
execute, deliver and perform its obligations under this Agreement, the
Indenture, the Notes and the Registration Rights Agreement (collectively, the
"TRANSACTION AGREEMENTS"), and to consummate the transactions contemplated
hereby and thereby, including (without limitation) (i) the issuance, sale and
delivery of the Notes hereunder and (ii) the filing of any Registration
Statement under and as defined in the Registration Rights Agreement.

         (h)  The execution, delivery, and performance of this Agreement and
the other Transaction Agreements and the consummation of the transactions
contemplated hereby and thereby do not and will not (i) conflict with or result
in a breach of any of the terms and provisions of, or constitute a default (or
an event which with notice or lapse of time, or both, would constitute a
default) under, or result in the creation or imposition of any lien, charge or
encumbrance upon any property or assets of the Company or any of the Significant
Subsidiaries (other than as disclosed in the Offering Circular) pursuant to, any
agreement, instrument, franchise, license or permit to which the Company or any
of the Significant Subsidiaries is a party or by which any of such corporations
or their respective properties or assets is bound, except for such conflicts,
breaches or defaults or liens, charges or encumbrances that would not have a
material adverse effect on the condition (financial or otherwise), earnings or
business affairs of the Company and its subsidiaries, taken as a whole, (ii)
violate or conflict with any provision of the articles of incorporation or
bylaws of the Company or any of the Significant Subsidiaries or any judgment,
decree, order, statute, rule or regulation of any 

                                       4

<PAGE>

court or any public, governmental or regulatory agency or body having 
jurisdiction over the Company or any of the Significant Subsidiaries or any 
of their respective properties or assets, except for such violations or 
conflicts that would not have a material adverse effect on the condition 
(financial or otherwise), earnings or  business affairs of the Company and 
its subsidiaries, taken as a whole, or (iii) require any consent, approval, 
authorization, order, registration, filing, qualification, license or permit 
of or with any court or any public, governmental or regulatory agency or body 
having jurisdiction over the Company or any of the Significant Subsidiaries 
or any of their respective properties or assets, except (in the case of 
clause (iii) above) as disclosed in the Offering Circular and except for any 
such consents, approvals, authorizations, orders, registrations, filings, 
qualifications, licenses and permits as have been made or obtained or as may 
be required under state securities or Blue Sky laws or the securities laws of 
any jurisdiction outside the United States in connection with the purchase 
and distribution of the Notes by the Initial Purchasers, and except where the 
failure to obtain or make any such consents, approvals, authorizations, 
orders, registrations, filings, qualifications, licenses and permits would 
not have a material adverse effect on the condition (financial or otherwise), 
earnings or business affairs of the Company and its subsidiaries, taken as a 
whole.

         (i)  This Agreement and the transactions contemplated hereby have been
duly and validly authorized by the Company.  This Agreement has been duly and
validly executed and delivered by the Company and constitutes the legal, valid
and binding obligation of the Company, enforceable against the Company in
accordance with its terms, except as such enforcement may be subject to or

moratorium and other similar laws relating to or affecting creditors' rights
generally, or general equitable principles (whether considered in a proceeding
in equity or at law), and except as the enforceability thereof may be limited by
considerations of public policy.

         (j)  The Indenture has been duly and validly authorized by the Company
and, when executed and delivered by the Company and the Trustee, will have been
duly and validly executed and delivered by the Company and will constitute the

         2.   PURCHASE, SALE AND DELIVERY OF THE NOTES.

         (a)  On the basis of the representations, warranties, covenants and
agreements herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to sell to the Initial Purchasers, and the Initial
Purchasers, severally and not jointly, agree to purchase from the Company, the
principal amount of the Firm Notes set forth opposite their respective names in
Schedule I hereto at a purchase price equal to 100% of such principal amount
LESS an underwriting discount of 3% of such 

                                       8

<PAGE>

principal amount.  Payment of the purchase price for, and delivery of, the 
Firm Notes will be made at the offices of Bear Stearns & Co. Inc. (the 
"Representative") at 245 Park Avenue, New York, New York at 10:00 a.m. (New 
York City time) on November 26, 1996, unless postponed in accordance with 
Section 9 hereof, or at such other place, time and date as may be mutually 
agreed in writing between you and the Company (the time and date of such 
payment and delivery being herein called the "CLOSING DATE").

         (b)  In addition, on the basis of the representations, warranties,
covenants and agreements herein contained, but subject to the terms and
conditions herein set forth, the Company hereby grants to the Initial Purchasers
the option to purchase, severally and not jointly, up to U.S. $9,750,000
aggregate principal amount of Optional Notes, for the sole purpose of covering
over-allotments in the sale of Firm Notes by the Initial Purchasers, at the same
purchase price to be paid by the Initial Purchasers to the Company for the Firm
Notes as set forth in Section 2(a).  This option may be exercised, in whole or
in part, on one occasion only at any time on or before the 30th day following
the date of the Offering Circular, by written notice to the Company by the
Representative on behalf of the Initial Purchasers.  Such notice shall set forth
the aggregate principal amount of Optional Notes to be purchased pursuant to
such exercise of the option and the date and time, as reasonably determined by
the Representative, when the Optional Notes are to be delivered (such date and
time being herein sometimes referred to as the "ADDITIONAL CLOSING DATE");
PROVIDED that the Additional Closing Date shall not be earlier than (x) the
Closing Date or (y) the second full business day after the date on which the
option shall have been exercised, nor later than the eighth full business day
after the date on which the option shall have been exercised (unless such date
and time are postponed in accordance with Section 9 hereof).  The principal
amount of the Optional Notes to be purchased by each Initial Purchaser upon such
exercise shall bear the same ratio to the aggregate principal amount of Optional
Notes being purchased upon such exercise as the principal amount of Firm Notes
set forth opposite the name of such Initial Purchaser in Schedule I hereto (or
such number increased as set forth in Section 9 hereof) bears to the aggregate
principal amount of Firm Notes, subject to such adjustments to eliminate
fractional amounts as the Representative in its sole discretion may make.

         (c)  At or prior to the Closing Date and the Additional Closing Date
(if any) hereunder, the Company shall execute and deliver for authentication the
Notes to be purchased and sold on such date and shall deposit such Notes (except
for those purchased by "institutional accredited investors" which shall be in
definitive form) with The Depositary Trust Company ("DTC") for the account or
accounts of participants in DTC (including Euroclear and CEDEL, as the case may
be) purchasing beneficial interests therein.  The Initial Purchasers shall pay
or cause the purchase price for such 

                                       9

<PAGE>

Notes to be paid to or upon the order of the Company by wire transfer of same 
day funds against delivery of such Notes to or for the respective accounts of 
the Initial Purchasers.  Certificates evidencing the Notes shall be 
registered in the name of Cede & Co. as nominee for DTC or such other name or 
names and in such authorized denominations as the Representative may request 
in writing at least two full business days prior to the Closing Date or the 
Additional Closing Date, as the case may be.  The Company will permit the 
Representative to inspect such certificates at the offices of the 
Representative at least one full business day prior to the Closing Date and 
the Additional Closing Date (if any).

         3.   SUBSEQUENT OFFERS AND RESALES OF THE NOTES.  The Initial
Purchasers and the Company hereby establish and agree to observe the following
procedures in connection with the offer and sale of the Notes:

         (a)  Each Initial Purchaser has advised the Company and the
Representative that it will offer the Notes for resale only upon the terms and
conditions set forth in this Agreement and the Offering Circular. The Notes have
not been and will not be registered under the Securities Act.  Each Initial
Purchaser agrees that it will not take, and acknowledges that the Company has
not taken, any action that would constitute a public offering of the Notes in
any jurisdiction and further agrees that, with respect to the offer or sale of
any Notes or the delivery or distribution of any Offering Circular, it will
comply with applicable laws and regulations in such jurisdictions or to which it
is otherwise subject.

         (b)  Each Initial Purchaser represents and warrants that (i) it is a
"qualified institutional buyer" within the meaning of Rule 144A or an
institution that is an "accredited investor" within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Securities Act and (ii) that neither it nor
any of its affiliates nor any person acting on behalf of it or any such

such terms are defined in Rule 502(c) under the Securities Act, in connection
with the offer or sale of the Notes.

         (c)  In connection with sales outside the United States, each Initial
Purchaser agrees that it will not offer, sell or deliver Notes (i) as part of
the distribution thereof at any time or (ii) otherwise until 40 days after
completion of the distribution, as determined by the Representative, to or for
the account or benefit of U.S. Persons (as defined in Regulation S).  Each
Initial Purchaser confirms that neither it nor any of its affiliates nor any
person acting on behalf of it or any such affiliate has engaged in any "directed
selling efforts" (as such term is defined in Regulation S) with respect to the

                                      10

<PAGE>

Notes and that it, its affiliates and each such other person has complied with
the offering restrictions required by Regulation S with respect to the Notes.

         (d)  Each of the Initial Purchasers acknowledges and agrees that it
has not and will not offer, sell or deliver the Notes in the United States or to
or for the account of any U.S. Person other than (i) distributors (as defined in
Regulation S), (ii) institutional buyers that are reasonably believed to be
"qualified institutional buyers" (as defined in Rule 144A) and (iii)
institutional purchasers that are reasonably believed by the Initial Purchasers
to be "accredited investors" (as defined in Rule 501(a) (1), (2), (3) or (7)
under the Securities Act) and that have executed and delivered to the
Representative a letter in the form of Annex A to the Offering Circular.

         (e)  Each of the Initial Purchasers has advised the Company and the
Representative that, prior to the confirmation of sale of any Notes, it will
have sent to each dealer, distributor or person that purchases any Notes from it
during the restricted period and receives a selling concession, fee or other
remuneration in connection therewith a confirmation or notice substantially to
the following effect:

         "The Notes have not been registered under the Securities Act of
         1933, as amended (the "Securities Act"), and may not be offered
         and sold within the United States or to, or for the account or
         benefit of U.S. persons (i) as part of the initial distribution
         thereof at any time or (ii) otherwise until 40 days after the
         later of the completion of the distribution of the Notes, as
         determined by Bear Stearns & Co. Inc., except in accordance with
         Regulation S or Rule 144A under the Securities Act."

         (f)  Each Initial Purchaser represents, warrants and agrees that (i)
it has not offered or sold and will not offer or sell Notes in the United
Kingdom, other than to persons whose ordinary activities involve them in
acquiring, holding, managing or disposing of investments (whether as principal
or agent) for the purposes of their businesses or otherwise in circumstances
that will not result in an offer to the public within the meaning of the Public
Offers of Securities Regulations 1995, (ii) it has complied and will comply with
all applicable provisions of the Public Offers of Securities Regulations 1995
and the Financial Services Act of 1986 with respect to anything done by it in
relation to the Notes in, from or otherwise involving the United Kingdom, and
(iii) it has only issued or passed on, and will only issue or pass on, to any
person in the United Kingdom any documents received by it in connection with the
issue of the Notes if the person is of a kind described in Article 11(c) of the
Financial Services Act of 1986 (Investment Advertisements) (Exemptions) Order
1988 or is a 

                                      11

<PAGE>

person to whom the documents may lawfully be issued or passed on. Each 
Initial Purchaser further agrees that it will not offer or sell any Notes 
directly or indirectly in Japan or to any resident of Japan except (A) 
pursuant to an exemption from the registration requirements of the Securities 
and Exchange Law of Japan and (B) in compliance with any applicable 
requirements of Japanese law.  Each Initial Purchaser further agrees that it 
will not offer or sell any Notes directly or indirectly in any province of 
Canada except in compliance with all requirements of applicable securities 
laws and that it will not offer or sell any Notes in the Republic of France.

         4.   COVENANTS OF THE COMPANY.  The Company covenants and agrees with
the Initial Purchasers that:

         (a)  If at any time prior to the Closing Date or the Additional
Closing Date (if any) any event shall have occurred as a result of which the
Offering Circular as then amended or supplemented would in the reasonable
judgment of the Initial Purchasers or the Company include an untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, the Company will notify the

of the Initial Purchasers an amendment or supplement (in form and substance
satisfactory to you) which will correct such statement or omission.

number of copies of the Offering Circular and all amendments thereof and

rules and regulations of the National Association of Securities Dealers, Inc.,
relating to trading in the PORTAL market.

         (e)  For a period of ninety (90) days from the date of the Offering
Circular, the Company will not, without the prior written consent of the
Representative, offer to sell, sell, contract to sell, grant any option for the
sale of, or otherwise dispose of, directly or indirectly, any shares of Common
Stock or any rights to acquire Common Stock, other than the Notes and other than
Common Stock or options issued or granted 

                                      12

the Company will obtain and deliver to the Representative a letter from each 
of its executive officers and directors confirming the agreement of such 
person not to engage in any of the aforementioned transactions on his or her 
own behalf during such ninety (90)-day period.

         (f)  So long as any of the Notes are "restricted securities" within
the meaning of Rule 144(a)(3) under the Securities Act, the Company will provide
to any holder of the Notes or to any prospective purchaser of the Notes
designated by any holder, upon request of such holder or prospective purchaser,
information required to be provided by Rule 144A(d)(4) of the Securities Act if
at the time of such request, the Company is not subject to the reporting
requirements under Section 13 or 15(d) of the Exchange Act.

         (g)  None of the Company, its subsidiaries, its affiliates or any
person acting on behalf of any of them (other than the Initial Purchasers and
their respective affiliates, as to whom this undertaking by the Company shall
not be deemed to apply) will solicit any offer to buy or offer or sell the Notes
by means of any form of general solicitation or general advertising (as those
terms are used in Regulation D under the Securities Act) or in any manner
involving a public offering within the meaning of the Securities Act.

         (h)  None of the Company, its subsidiaries, its affiliates or any
person acting on behalf of any of them (other than the Initial Purchasers and
their respective affiliates, as to whom this undertaking by the Company shall
not be deemed to apply) will offer to sell, sell or solicit offers to buy or
otherwise negotiate in respect of the sale of any security (as defined in the
Securities Act) that would be integrated with the sale of the Notes so as to
require the registration of the Notes under the Securities Act.

         (i)  During the period of three (3) years from and after the Closing

resell any Notes that may have been purchased or otherwise acquired by them,
except in a transaction registered or exempt from registration under the
Securities Act.

         (j)  None of the Company, its subsidiaries, its affiliates or any
person acting on behalf of any of them (other than the Initial Purchasers and

shall not be deemed to apply) will comply with the offering restrictions of 
Regulation S with respect to those Notes offered and sold pursuant thereto.

         (k)  The Company will cooperate with the Initial Purchasers in
arranging for the Notes to be accepted for clearance and settlement through
Euroclear, CEDEL and The Depository Trust Company.

         (l)  Each of the Notes will bear, to the extent applicable, the legend

the time period and upon the other terms stated therein, except after the Notes
are resold in a transaction registered under the Securities Act.

         (m)  The Company will use its reasonable commercial efforts to obtain
a rating of the Notes by Standard & Poor's Corporation and will provide to such
organization such information as such organization reasonably shall require in
order to issue a rating of the Notes.

                      (viii) No consent, approval, authorization, order, 
         registration or qualification of or with any federal or 
         Pennsylvania governmental agency or body is required for the issue 
         and sale of the Notes by the Company and compliance by the Company 
         with the provisions of this Agreement and the Registration Rights 
         Agreement, except for the registration of the Notes under the 
         Securities Act (as to which no opinion is expressed in this 
         paragraph), and such 

                                      16

<PAGE>

         consents, approvals, authorizations, registrations or 
         qualifications as may be required under state securities or Blue 
         Sky laws or the securities laws of any jurisdiction outside the 
         United States in connection with the purchase and resale of the 
         Notes by the Initial Purchasers (as to which no opinion is 
         expressed).

                        (ix) The statements made in the Offering Circular 
         under the heading "Certain Tax Considerations," insofar as they 
         purport to constitute summaries of matters of United States federal 
         tax law and regulations or legal conclusions with respect thereto, 
         constitute accurate summaries of the matters described therein in 
         all material respects.
         
                         (x) No registration under the Securities Act of the 
         Notes or the shares of Common Stock issuable upon conversion of the 
         Notes in accordance with the Indenture, and no qualification of the 
         Indenture under the Trust Indenture Act of 1939, as amended, is 
         required for the offer and sale of the Notes by the Company to the 
         Initial Purchasers or the initial reoffer and resale of the Notes 
         by the Initial Purchasers solely in the manner contemplated by the 
         Offering Circular and this Agreement.
         
                        (xi) The authorized capital stock of the Company 
         conforms as to legal matters to the description thereof contained 
         in the Offering Circular under the heading "Description of Capital 
         Stock."  The outstanding shares of the Company's Common Stock have 
         been duly authorized and validly issued and are fully paid and 
         nonassessable.  The shares of Common Stock initially issuable upon 
         conversion of the Notes have been duly authorized and reserved for 
         issuance upon such conversion, except for and subject to the 
         limitations described in the Offering Circular on the number of 
         such shares available for that purpose, and, when issued and 
         delivered upon such conversion in accordance with the provisions of 
         the Indenture (assuming payment for and delivery of the Notes in 
         accordance with this Agreement), will be validly issued, fully paid 
         and nonassessable and no further approval or authority of the 
         shareholders or the Board of Directors of the Company will be 
         required for such issuance.
         
                       (xii) There are no preemptive rights to subscribe for 
         or purchase shares of the Company's Common Stock provided in the 
         Company's articles of incorporation or by-laws or, to the knowledge 
         of such counsel, in any agreement to which the Company is a party.

                      (xiii) To the knowledge of such counsel, no holders of 
         securities of the Company have rights to require the registration 
         of such securities because 

                                      17

<PAGE>

         of the filing by the Company of the Shelf Registration Statement or the
         New Notes Registration Statement (as such terms are defined in the 
         Offering Circular) except such as have been validly waived.
         
                       (xiv) Except as disclosed in the Offering Circular 
         and any document incorporated by reference therein, and except for 
         stock options outstanding under the Company's existing stock option 
         plan(s), to the knowledge of such counsel there are no outstanding 
         options, warrants or other rights calling for the issuance of, and 
         no commitments or obligations on the part of the Company to issue, 
         any shares of capital stock of the Company or any security 
         convertible into or exchangeable for capital stock of the Company.

In addition, such counsel shall state that such counsel has participated in 
conferences with officers and other representatives of the Company, 
representatives of the independent public accountants for the Company, 
representatives of the Initial Purchasers and Counsel for the Initial 
Purchasers at which the contents of the Offering Circular and related matters 
were discussed and, although such counsel did not independently verify such 
information and is not passing upon and does not assume any responsibility 
for the accuracy, completeness or fairness of the statements contained in the 
Offering Circular, on the basis of the foregoing (relying as to the factual 
matters upon the statements of officers and other representatives of the 
Company and public officials) no facts have come to such counsel's attention 
that caused such counsel to believe that the Offering Circular (other than 
the financial statements and notes thereto and other financial and accounting 
data included or incorporated by reference therein, or omitted therefrom, as 
to which such counsel need express no belief) at the date of the Offering 
Circular and as of the Closing Date contained or contains an untrue statement 
of a material fact or omitted or omits to state a material fact required to 
be stated therein or necessary to make the statements therein, in light of 
the circumstances under which they were made, not misleading.

         In rendering such opinion, such counsel may rely (x) as to matters 
involving the application of laws other than the laws of the United States 
and jurisdictions in which such counsel are admitted, to the extent such 
counsel may deem proper and to the extent specified in such opinion, if at 
all, upon an opinion or opinions (in form and substance reasonably 
satisfactory to Counsel for the Initial Purchasers) of other counsel, 
reasonably acceptable to Counsel for the Initial Purchasers, familiar with 
the applicable laws (it being understood, however, that with respect to the 
validity and binding effect of the Indenture, the Notes and the Registration 
Rights Agreement, counsel may opine as if such instruments were governed by 
the laws of the Commonwealth of Pennsylvania); (y) as to matters of fact, to 
the extent they deem 

                                      18

<PAGE>

proper, on the representations and warranties of the Company contained 
herein, on certificates of responsible officers of the Company and 
certificates or other written statements of officers of departments of 
various jurisdictions having custody of documents respecting the corporate 
existence or good standing of the Company and its subsidiaries, provided that 
copies of any such statements or certificates shall be delivered to Counsel 
for the Initial Purchasers.  The opinion of such counsel for the Company 
shall state that the opinion of any such other counsel is in form 
satisfactory to such counsel and, in their opinion, the Initial Purchasers 
and they are justified in relying thereon.

         (b)  All proceedings taken in connection with the sale of the Notes as
herein contemplated shall be reasonably satisfactory in form and substance to
you and to Counsel for the Initial Purchasers, and the Initial Purchasers shall
have received from said Counsel for the Initial Purchasers a favorable opinion,
dated as of the Closing Date with respect to the issuance and sale of the Notes,
the Offering Circular and such other related matters as you may reasonably
require, and the Company shall have furnished to Counsel for the Initial
Purchasers such documents as they reasonably may request for the purpose of
enabling them to pass upon such matters.

         (c)  At the Closing Date you shall have received a certificate of the
Chief Executive Officer and Chief Financial Officer of the Company, dated the
Closing Date, to the effect that (i) as of the date hereof and as of the Closing
Date, the representations and warranties of the Company set forth in Section 1
hereof are accurate in all material respects, (ii) as of the Closing Date, the
obligations of the Company to be performed hereunder on or prior thereto have
been duly performed in all material respects and (iii) subsequent to the
respective dates as of which information is given in the Offering Circular, the
Company and its subsidiaries have not sustained any material loss or
interference with their respective businesses or properties from fire, flood,
hurricane, accident or other calamity, whether or not covered by insurance, or
from any labor dispute or any legal or governmental proceeding, and there has
not been any material adverse change, or any development involving a material
adverse change, in the business, properties, operations, condition (financial or
otherwise), or results of operations of the Company and its subsidiaries taken
as a whole, except in each case as disclosed in the Offering Circular.

         (d)  At the time this Agreement is executed and at the Closing Date,
you shall have received a letter, from Coopers & Lybrand L.L.P., independent
accountants for the Company, dated, respectively, as of the date of this
Agreement and as of the Closing Date and addressed to the Initial Purchasers, in
form, scope and substance as shall have been previously agreed to by the
Representative.

                                      19

<PAGE>

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

         (f)  You shall have received from each person who is a director or
executive officer (as defined in the proxy rules of the Securities and Exchange
Commission) of the Company an agreement to the effect that during the period of
90 days from the date of the Offering Circular, such person will not, directly
or indirectly, without the prior written consent of the Representative, offer to
sell, sell, contract to sell, grant any option or rights to acquire or purchase
any option to sell, or otherwise dispose of, any shares of Common Stock.

         (g)  At the Closing Date, the Notes shall have been approved for
quotation in the PORTAL market.

         If any of the conditions specified in this Section 6 shall not have
been fulfilled in all material respects when and as required by this Agreement,
or if any of the certificates, opinions, written statements or letters furnished
to you or to Counsel for the Initial Purchasers pursuant to this Section 6 shall
not be in all material respects reasonably satisfactory in form and scope to the
Representative and to Counsel for the Initial Purchasers, all obligations of the
Initial Purchasers hereunder may be canceled by the Representative at, or at any
time prior to, the Closing Date and the obligations of the Initial Purchasers to
purchase the Optional Notes may be canceled by the Representative at, or at any
time prior to, the Additional Closing Date.  Notice of such cancellation shall
be given to the Company in writing, or by telephone, telex or telegraph,
confirmed in writing.

         7.   INDEMNIFICATION.

         (a)  The Company agrees to indemnify and hold harmless each Initial
Purchaser and each person, if any, who controls any Initial Purchaser within the
meaning of Section 15 of the Securities Act or Section 20(a) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), against any and all
losses, liabilities, claims, damages and expenses whatsoever as incurred
(including but not limited to attorneys' fees and any and all expenses
whatsoever incurred in investigating, preparing or defending against any
litigation, commenced or threatened, or any claim whatsoever, and any and all
amounts paid in settlement of any claim or litigation), joint or several, to
which they or any of them may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages
or expenses (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue 

                                      20

<PAGE>

statement of a material fact contained in the Offering Circular or any 
related Preliminary Offering Circular or any amendment or supplement thereto 
or arise out of or are based upon the omission or alleged omission to state 
therein a material fact required to be stated therein or necessary to make 
the statements therein, in light of the circumstances under which they were 
made, not misleading; PROVIDED, HOWEVER, that the Company will not be liable 
in any such case to the extent but only to the extent that any such loss, 
liability, claim, damage or expense arises out of or is based upon any such 
untrue statement or alleged untrue statement or omission or alleged omission 
made therein in reliance upon and in conformity with written information 
furnished to the Company by or on behalf of any Initial Purchaser through the 
Representative expressly for use therein, and PROVIDED FURTHER, that the 
foregoing indemnity with respect to any untrue statement contained in or 
omission from a Preliminary Offering Circular shall not inure to the benefit 
of any Initial Purchaser (or any person controlling such Initial Purchaser) 
from whom the person asserting any such loss, liability, claim, damage or 
expense purchased any of the Notes if a copy of the Offering Circular (as 
then amended or supplemented if the Company shall have furnished any 
amendments or supplements thereto) was not sent or given by or on behalf of 
such Initial Purchaser to such person at or prior to the written confirmation 
of the sale of such Notes to such person, and if the Offering Circular (as so 
amended or supplemented) would have cured the defect giving rise to such 
loss, claim, damage or liability. This indemnity agreement will be in 
addition to any liability which the Company may otherwise have including 
under this Agreement.

         (b)  Each Initial Purchaser severally, and not jointly, agrees to
indemnify and hold harmless the Company, each of the directors of the Company,
each of the officers of the Company, and each other person, if any, who controls
the Company within the meaning of Section 15 of the Securities Act or Section
20(a) of the Exchange Act, against any losses, liabilities, claims, damages and
expenses whatsoever as incurred (including but not limited to attorneys' fees
and any and all expenses whatsoever incurred in investigating, preparing or
defending against any litigation, commenced or threatened, or any claim
whatsoever, and any and all amounts paid in settlement of any claim or
litigation), jointly or severally, to which they or any of them may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as such
losses, liabilities, claims, damages or expenses (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in the Offering Circular, or any related
Preliminary Offering Circular, or in any amendment thereof or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading, in each case to the extent, but only to the extent, that
any such 

                                      21

<PAGE>

loss, liability, claim, damage or expense arises out of or is based upon any 
such untrue statement or alleged untrue statement or omission or alleged 
omission made therein in reliance upon and in conformity with written 
information furnished to the Company by or on behalf of any Initial Purchaser 
through the Representative expressly for use therein; PROVIDED, HOWEVER, that 
in no case shall any Initial Purchaser be liable or responsible for any 
amount in excess of the aggregate principal amount of the Notes purchased by 
such Initial Purchaser hereunder.  This indemnity will be in addition to any 
liability which any Initial Purchaser may otherwise have including under this 
Agreement.  The Company acknowledges that the statements set forth in the 
last paragraph of the cover page and under the caption "Plan of Distribution" 
in the Offering Circular constitute the only information furnished in writing 
by or on behalf of any Initial Purchaser through Bear Stearns expressly for 
use in the Offering Circular or in any amendment thereof or supplement 
thereto, as the case may be. 

         (c)  Promptly after receipt by an indemnified party under subsection
(a) or (b) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify each party against whom
indemnification is to be sought in writing of the commencement thereof (but the
failure so to notify an indemnifying party shall not relieve it from any
liability which it may have otherwise than under this Section 7).  In case any
such action is brought against any indemnified party, and it notifies an
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein, and to the extent it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party.  Notwithstanding the
foregoing, the indemnified party or parties shall have the right to employ its
or their own counsel in any such case, but the fees and expenses of such counsel
shall be at the expense of such indemnified party or parties unless (i) the
employment of such counsel shall have been authorized in writing by one of the
indemnifying parties in connection with the defense of such action, (ii) the
indemnifying parties shall not have employed counsel to have charge of the
defense of such action within a reasonable time after notice of commencement of
the action, or (iii) such indemnified party or parties shall have reasonably
concluded that there may be defenses available to it or them which are different
from or additional to those available to one or all of the indemnifying parties
(in which case the indemnifying parties shall not have the right to direct the
defense of such action on behalf of the indemnified party or parties), in any of
which events such fees and expenses shall be borne by the indemnifying parties. 
In no event shall the indemnifying party be liable for the fees and expenses of
more than one counsel in connection with any one such action or separate but
similar related actions in the same jurisdiction arising out of the same general

                                      22

<PAGE>

allegations or circumstances.  Anything in this subsection to the contrary
notwithstanding, an indemnifying party shall not be liable for any settlement of
any claim or action effected without its written consent; PROVIDED, HOWEVER,
that such consent was not unreasonably withheld.

         8.   CONTRIBUTION.  In order to provide for contribution in
circumstances in which the indemnification provided for in Section 7 hereof is
for any reason held to be unavailable from any indemnifying party, or to any
indemnified party, or is insufficient to hold harmless a party indemnified
thereunder, the Company and the Initial Purchasers shall contribute to the
aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated by such indemnification provision (including any investigation,
legal and other expenses incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claims asserted, but after
deducting in the case of losses, claims, damages, liabilities and expenses
suffered by the Company any contribution received by the Company from persons,
other than the Initial Purchasers, who may also be liable for contribution,
including persons who control the Company within the meaning of Section 15 of
the Securities Act or Section 20(a) of the Exchange Act, officers and directors
of the Company) as incurred to which the Company and one or more of the Initial
Purchasers may be subject, in such proportions as is appropriate to reflect the
relative benefits received by the Company and the Initial Purchasers from the
offering of the Notes or, if such allocation is not permitted by applicable law
or indemnification is not available as a result of the indemnifying party not
having received notice as provided in Section 7 hereof, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company and the Initial Purchasers in connection with
the statements or omissions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received by the Company and the Initial Purchasers shall
be deemed to be in the same proportion as (x) the total proceeds from the
offering (net of underwriting discounts and commissions but before deducting
expenses) received by the Company and (y) the underwriting discounts and
commissions received by the Initial Purchasers respectively.  The relative fault
of the Company and of the Initial Purchasers 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 Company or the Initial Purchasers and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Company and the Initial
Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 8 were determined by pro rata allocation (even if the
Initial Purchasers were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations

                                      23

<PAGE>

referred to above.  Notwithstanding the provisions of this Section 8, (i) in no
case shall any Initial Purchaser be liable or responsible for any amount in
excess of the underwriting discount applicable to the Notes purchased by such
Initial Purchaser hereunder, (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation and (iii) no Initial Purchaser shall be required to
contribute any amount in excess of the amount by which the total price at which
the Note purchased by it and sold in the Offering were offered to subsequent
purchasers exceeds the amount of any damages that such Initial Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission.  For purposes of this Section 8, each
person, if any, who controls an Initial Purchaser within the meaning of Section
15 of the Securities Act or Section 20(a) of the Exchange Act shall have the
same rights to contribution as such Initial Purchaser, and each person, if any,
who controls the Company within the meaning of Section 15 of the Securities Act
or Section 20(a) of the Exchange Act, each officer and each director of the
Company shall have the same rights to contribution as the Company, subject in
each case to clauses (i) and (ii) of this Section 8.  Any party entitled to
contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties, notify each party or
parties from whom contribution may be sought, but the omission to so notify such
party or parties shall not relieve the party or parties from whom contribution
may be sought from any obligation it or they may have under this Section 8 or
otherwise.  No party shall be liable for contribution with respect to any action
or claim settled without its consent; PROVIDED, HOWEVER, that such consent was
not unreasonably withheld.

         9.   DEFAULT BY AN INITIAL PURCHASER.  If either of the Initial 
Purchasers shall fail at the Closing Date to purchase the Notes which it is 
obligated to purchase under this Agreement (the "Defaulted Notes"), the 
non-defaulting Initial Purchaser shall have the right, within 24 hours 
thereafter, to make arrangements for it to purchase all, but not less than 
all, of the Defaulted Notes upon the terms herein set forth; PROVIDED, 
HOWEVER, that if the non-defaulting Initial Purchaser shall not have 
completed such arrangements within such 24-hour period, then, upon the 
expiration of such 24-hour period, this Agreement shall terminate without 
liability on the part of the non-defaulting Initial Purchaser.

         No action taken pursuant to this Section shall relieve the defaulting
Initial Purchaser from liability in respect of its default.

                                      24

<PAGE>

         In the event of any such default which does not result in a
termination of this Agreement, either the non-defaulting Initial Purchaser or
the Company shall have the right to postpone the Closing Date for a period not
exceeding seven days in order to effect any required changes in the Offering
Circular or in any other documents or arrangements.

         10.  SURVIVAL OF REPRESENTATIONS AND AGREEMENTS.  All representations
and warranties, covenants and agreements of the Initial Purchasers and the
Company contained in this Agreement, including the agreements contained in
Section 5, the indemnity agreements contained in Section 7 and the contribution
agreements contained in Section 8, shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of any Initial
Purchasers or any agent, representative or controlling person thereof or by or
on behalf of the Company, any of its officers and directors or any controlling
person thereof, and shall survive delivery of and payment for the Notes to and
by the Initial Purchasers.  The representations contained in Section 1 and the
agreements contained in Sections 5, 7, 8 and 11(c) hereof shall survive the
termination of this Agreement, including termination pursuant to Section 9 or 11
hereof.

         11.  TERMINATION.

         (a)  The Representative shall have the right to terminate this
Agreement at any time prior to the Closing Date or the obligations of the
Initial Purchasers to purchase the Optional Notes at any time prior to the
Additional Closing Date, as the case may be, if (A) any domestic or
international event, act or occurrence shall have materially disrupted, or in
the Representative's reasonable opinion will in the immediate future materially
disrupt, the United States or international securities markets; or (B) trading
on the New York Stock Exchange shall have been suspended, or materially limited;
or (C) a banking moratorium shall have been declared by any United States
federal or New York or Pennsylvania state authority or if any new restriction
materially adversely affecting the distribution of the Firm Notes or the
Optional Notes, as the case may be, shall have become effective; or (D) any
"nationally recognized statistical rating organization" (as defined for purposes
of Rule 436(g) under the Securities Act) shall have announced that it is (i)
downgrading its rating assigned to any class of the Company's debt securities or
(ii) reviewing any such rating with a view to possible downgrading or with
negative implications; or (E) there shall have occurred any outbreak or
escalation of hostilities involving the United States, or a declaration of war
or national emergency by the United States, or any change in political,
financial or economic conditions the effect of which is such, in the judgment of
the Representative, to make it impracticable or inadvisable to proceed with the
offering, sale and delivery of the Firm 

                                      25

<PAGE>

Notes or the Optional Notes, as the case may be, on the terms contemplated by 
the Offering Circular.

         (b)  Any notice of termination pursuant to this Section 11 shall be by
telephone, telex, or telegraph, confirmed in writing by letter.

         (c)  If this Agreement shall be terminated pursuant to any of the
provisions hereof (otherwise than pursuant to Section 9 or 11(a) hereof), or if
the sale of the Notes provided for herein is not consummated because any
condition to the obligations of the Initial Purchasers set forth herein is not
satisfied or because of any refusal, inability or failure on the part of the
Company to perform any agreement herein or comply with any provision hereof, the
Company will, upon demand by the Representative, reimburse the Initial
Purchasers for all reasonable out-of-pocket expenses (including the reasonable
fees and expenses of Counsel for the Initial Purchasers), incurred by the
Initial Purchasers solely and directly in connection with the transactions
contemplated by this Agreement, and thereafter the Company shall have no further
liability to the Initial Purchaser.

         12.  NOTICE.  All communications hereunder, except as may be otherwise
specifically provided herein, shall be in writing and shall be mailed,
delivered, or telexed or telegraphed and confirmed in writing, (i) if to either
of the Initial Purchasers, to such Initial Purchaser in care of Bear, Stearns &
Co. Inc., 245 Park Avenue, New York, New York 10167, Attention:  Brian A.
McCarthy, Senior Managing Director or (ii) if to the Company, to the Company at
3440 Lehigh Street, Allentown, Pennsylvania 18103, Attention:  Cameron Waite,
Chief Financial Officer.

         13.  PARTIES.  This Agreement shall inure solely to the benefit of,
and shall be binding upon, the Initial Purchasers and the Company and their
respective successors and assigns, and no other person shall have or be deemed
to have any legal or equitable right, remedy or claim under or in respect of or
by virtue of this Agreement or any provision hereof.  The term "successors and
assigns" shall not include a purchaser, in its capacity as such, of Notes from
any of the Initial Purchasers.

         14.  GOVERNING LAW.  This Agreement shall be governed by the laws of
the State of New York.

                                      26

                                AND EXCHANGE OF NOTES

         Section 2.1  DESIGNATION, AMOUNT AND ISSUE OF NOTES.  The Notes shall
be designated as "6-1/4% Convertible Subordinated Notes Due 2003."  Notes not to
exceed the aggregate principal amount of $65,000,000 (up to $74,750,000
aggregate principal amount assuming the full exercise of the over-allotment
option granted to the initial purchasers of the Notes) upon the execution of
this Indenture, or from time to time thereafter, may be executed by the Company
and delivered to the Trustee for authentication, and the Trustee shall thereupon
authenticate and make available for delivery said Notes upon the written order
of the Company, signed by its (a) Chief Executive Officer, President, Chief
Operating Officer or Chief Financial Officer, and (b) any Treasurer or Secretary
or any Assistant Secretary, without any further action by the Company hereunder.

         Section 2.2  FORM OF NOTES.  Notes sold to Institutional Accredited
Investors that are neither QIBs nor Non-U.S. Persons will be issued in
definitive form in substantially the form of Exhibit A hereto, with the legends
in substantially the form indicated in Exhibit A hereto and such other legends
as may be applicable thereto, which definitive Notes shall be registered in the
name of the holders thereof, duly executed by the Company and authenticated by
the Trustee or the authenticating agent as provided herein.     

         Notes held by QIBs shall be issued initially in the form of one or
more global Notes (the "Restricted Global Note"), substantially in the form of
Exhibit B hereto, with the legends as may be applicable thereto, which
Restricted Global Note shall be deposited on behalf of the holders of the Notes
represented thereby with the Depositary and registered in the name of Cede & Co.
("Cede") as nominee of the Depositary, duly executed by the Company and
authenticated by the Trustee or the authenticating agent as provided herein.

         Notes offered and sold to persons outside the United States (each, a
"Non-U.S. Person") in reliance on Regulation S shall be issued initially in the
form of a global Note (the "Regulation S Global Note"), substantially in the
form of Exhibit C hereto, with the legends in substantially the form set forth
in Exhibit C hereto and such other legends as may be applicable thereto, which
Regulation S Global Note shall be deposited on behalf of the holders of the
Notes represented thereby with or on behalf of the Depositary, and registered in


                                      11
<PAGE>

the name of Cede as the Depositary's nominee, duly executed by the Company and
authenticated by the Trustee or an authenticating agent as provided herein, for
credit to the accounts of Euroclear and Cedel (or such other accounts as they
may direct).  Prior to and including the 40th day after the later of the
commencement of the offering of the Notes and the Closing Date (the "Restricted
Period"), beneficial interests in the Regulation S Global Note may only be held
through Euroclear or Cedel Bank.  During the Restricted Period, interests in the
Regulation S Global Note may be exchanged for interests in the Restricted Global
Note or for definitive Notes only in accordance with the certification
requirements described in this Article II.

         QIBs and, after the expiration of the Restricted Period, Non-U.S.
Persons may request that definitive Notes be issued in exchange for Notes
represented by the applicable global Note.  In addition, if at any time the
Depositary for the global Notes is unable or unwilling to act as Depositary and
no successor Depositary is appointed pursuant to Section 2.5(c) herein,
definitive Notes may be issued in exchange for Notes represented by the global
Notes.  Unless determined otherwise by the Company in accordance with applicable
law, after the expiration of the Restricted Period, definitive Notes issued upon
transfer or exchange of beneficial interests in Notes represented by the
Regulation S Global Note shall not bear the legend set forth in Section 2.5(c). 
Any definitive Note issued to a QIB pursuant to this paragraph shall bear the
legend set forth in Section 2.5(c).

         Any of the Notes may have such letters, numbers or other marks of
identification and such notations, legends and endorsements as the Company
officers executing the same may approve (execution thereof to be conclusive
evidence of such approval) and as are not inconsistent with the provisions of
this Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Notes may be listed, or to conform to usage.

         Any global Note shall represent such of the outstanding Notes as shall
be specified therein and shall provide that it shall represent the aggregate
amount of outstanding Notes from time to time endorsed thereon and that the
aggregate amount of outstanding Notes represented thereby may from time to time
be increased or reduced to reflect transfers or exchanges permitted hereby.  Any
endorsement of a global Note to reflect the amount of any increase or decrease
in the amount of outstanding Notes represented thereby shall be made by the
Trustee or the Custodian, at the direction of the Trustee, in such manner and
upon written instructions given by the holder of such Notes in accordance with
the Indenture.  Payment of principal of and


                                      12
<PAGE>

interest and premium, if any, on any global Note shall be made in accordance 
with the provisions of Section 2.3 hereof.

         The terms and provisions contained in the forms of Notes attached as
Exhibits A, B and C hereto shall constitute, and are hereby expressly made, a
part of this Indenture and to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

         Section 2.3   DATE AND DENOMINATION OF NOTES; PAYMENTS OF INTEREST. 
The Notes shall be issuable in registered form only without coupons in
denominations of $1,000 principal amount and integral multiples thereof.  Every
Note shall be dated the date of its authentication, shall bear interest from
November 26, 1996 and shall be payable semiannually on each June 1, and 
December 1, commencing June 1, 1997, as specified on the faces of the forms of 
Notes, attached as Exhibits A, B and C hereto.

         The person in whose name any Note (or its Predecessor Note) is
registered at the close of business on any record date with respect to any
interest payment date (including any Note that is converted after the record
date and on or before the interest payment date) shall be entitled to receive
the interest payable on such interest payment date notwithstanding the
cancellation of such Note upon any transfer, exchange or conversion subsequent
to the record date and prior to such interest payment date.  Interest may, at
the option of the Company, be paid by check mailed to the address of such person
as it appears on the Note register; provided that, with respect to any holder of
Notes with an aggregate principal amount equal to or in excess of $5,000,000, at
the request (such request to include appropriate wire instructions) of such
holder in writing to the Trustee on or before the record date preceding any
interest payment date, interest on such holder's Notes shall be paid by wire
transfer in immediately available funds.  The term "record date" with respect to
any interest payment date shall mean the May 15 or November 15 preceding said
June 1, or December 1.

         None of the Company, the Trustee or any paying agent shall have any
responsibility or liability for any aspect of the records relating to or payment
made on account of beneficial ownership interests in the global Notes or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.  

         Interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months.


                                      13
<PAGE>

         Any interest on any Note that is payable, but is not punctually paid
or duly provided for, on any said June 1, or December 1, (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Noteholder on
the relevant record date by virtue of his having been such Noteholder; and such
Defaulted Interest shall be paid by the Company, at its election in each case,
as provided in clause (1) or (2) below:

         (1)  The Company may elect to make payment of any Defaulted Interest
    to the persons in whose names the Notes (or their respective Predecessor
    Notes) are registered at the close of business on a special record date for
    the payment of such Defaulted Interest, which shall be fixed in the
    following manner.  The Company shall notify the Trustee in writing of the
    amount of Defaulted Interest to be paid on each Note and the date of the
    payment (which shall be not less than 25 days after the receipt by the
    Trustee of such notice, unless the Trustee shall consent to an earlier
    date), and at the same time, the Company shall deposit with the Trustee an
    amount of money equal to the aggregate amount to be paid in respect of such
    Defaulted Interest or shall make arrangements satisfactory to the Trustee
    for such deposit prior to the date of the proposed payment, such money when
    deposited to be held in trust for the benefit of the persons entitled to
    such Defaulted Interest as in this clause provided.  Thereupon, the Trustee
    shall fix a special record date for the payment of such Defaulted Interest,
    which shall be not more than 15 days and not less than 10 days prior to the
    date of the payment and not less than 10 days after the receipt by the
    Trustee of the notice of the proposed payment.  The Trustee shall promptly
    notify the Company of such special record date and, in the name and at the
    expense of the Company, shall cause notice of the payment of such Defaulted
    Interest and the special record date therefor to be mailed, first-class
    postage prepaid, to each Noteholder at his address as it appears in the
    Note register, not less than 10 days prior to such special record date. 
    Notice of the proposed payment of such Defaulted Interest and the special
    record date therefor having been so mailed, such Defaulted Interest shall
    be paid to the persons in whose names the Notes (or their respective
    Predecessor Notes) were registered at the close of business on such special
    record date and shall no longer be payable pursuant to the following
    clause (2).

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


                                      14
<PAGE>

    such manner of payment shall be deemed practicable by the Trustee.

         Section 2.4  EXECUTION OF NOTES.  The Notes shall be signed in the
name and on behalf of the Company by the signature of its Chief Executive
Officer, President, Chief Operating Officer or Chief Financial Officer and
attested by the signature of its Treasurer, Secretary or any of its Assistant
Secretaries (any of which signatures may be printed, engraved or otherwise
reproduced thereon, by facsimile or otherwise).  Only such Notes as shall bear
thereon a certificate of authentication substantially in the form set forth on
forms of Notes attached as Exhibits A, B and C hereto, manually executed by the
Trustee (or an authenticating agent appointed by the Trustee as provided by
Section 16.14), shall be entitled to the benefits of this Indenture or be valid
or obligatory for any purpose.  Such certificate by the Trustee (or such an
authenticating agent) upon any Note executed by the Company shall be conclusive
evidence that the Note so authenticated has been duly authenticated and
delivered hereunder and that the holder is entitled to the benefits of this
Indenture.

         In case any officer of the Company who shall have signed any of the
Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution of this Indenture any such
person was not such an officer.

         Section 2.5  EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES; 
RESTRICTIONS ON TRANSFER; DEPOSITARY.

         (a)  The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register maintained in such office and in any
other office or agency of the Company designated pursuant to Section 4.2 being
herein sometimes collectively referred to as the "Note register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Notes and of transfers of Notes.  Such Note
register shall be in written form or in any form capable of being converted into
written form within a reasonable period of time.  The Trustee is hereby
appointed "Note registrar" for the purpose of registering Notes and transfers of
Notes as herein provided.  The Company may appoint one or more co-registrars.


                                      15
<PAGE>

         Upon surrender for registration of transfer of any Note to the Note
registrar or any co-registrar and satisfaction of the requirements for such
transfer set forth in this Section 2.5, the Company shall execute, and the
Trustee shall authenticate and make available for delivery, in the name of the
designated transferee or transferees, one or more new Notes of any authorized
denominations and of a like aggregate principal amount and bearing such
restrictive legends as may be required by Sections 2.5(c) and (d).

         Notes may be exchanged for other Notes of any authorized denominations
and of a like aggregate principal amount, upon surrender of the Notes to be
exchanged at any such office or agency.  Whenever any Notes are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
make available for delivery, the Notes that the Noteholder making the exchange
is entitled to receive bearing certificate numbers not contemporaneously
outstanding.

         All Notes presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company, the Trustee, the Note registrar
or any co-registrar) be duly endorsed, or be accompanied by a written instrument
of transfer in form satisfactory to the Company, executed by the Noteholder
thereof or his attorney duly authorized in writing.

         No service charge shall be charged to the Noteholder for any exchange
or registration of transfer of Notes, but the Company may require payment of a
sum sufficient to cover any tax, assessments or other governmental charges that
may be imposed in connection therewith.

         None of the Company, the Trustee, the Note registrar or any
co-registrar shall be required to exchange or register a transfer of (a) any
Notes for a period of 15 days next preceding the mailing of a notice of
redemption, (b) any Notes called for redemption or, if a portion of any Note is
selected or called for redemption, such portion thereof selected or called for
redemption, (c) any Notes surrendered for conversion or, if a portion of any
Note is surrendered for conversion, such portion thereof surrendered for
conversion or (d) any Notes surrendered for repurchase pursuant to Section 3.5
or, if a portion of any Note is surrendered for repurchase pursuant to 
Section 3.5, such portion thereof surrendered for repurchase pursuant to 
Section 3.5.

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


                                      16
<PAGE>

of which is effectuated by the Trustee pursuant to this Section 2.5, shall be 
accompanied by an Officers' Certificate of the Company, executed by a 
Responsible Officer thereof, certifying that such transfer, exchange and/or 
registration is authorized by the Company and permitted hereunder.

         (b)  So long as the Notes are eligible for book-entry settlement with
the Depositary, or unless otherwise required by law, all Notes to be traded on
the PORTAL Market shall be represented by the Restricted Global Note registered
in the name of the Depositary or the nominee of the Depositary.  The transfer
and exchange of beneficial interests in any global Note that does not involve
the issuance of a definitive Note or the transfer of interests to another global
Note shall be effected through the Depositary (and not the Trustee or the
Custodian) in accordance with this Indenture (including the restrictions on
transfer set forth herein) and the procedures of the Depositary therefor. 
Neither the Trustee nor the Custodian (in such respective capacities) shall have
any responsibility for the transfer and exchange of beneficial interests in such
global Note that does not involve the issuance of a definitive Note or the
transfer of interests to another global Note.

         Any beneficial interest in Notes represented by the Restricted Global
Note that is transferred to an Institutional Accredited Investor that is not a
QIB shall be delivered in the form of a definitive Note in registered form in
accordance with Section 2.2 herein and shall cease to be an interest in Notes
represented by such Restricted Global Note and accordingly shall thereafter be
subject to all transfer restrictions and other procedures applicable to a
definitive Note held by Institutional Accredited Investors.

         Any transfer of a beneficial interest in a global Note that cannot be
effected through book-entry settlement must be effected by the delivery to the
transferee (or its nominee) of a definitive Note or Notes registered in the name
of the transferee (or its nominee) on the books maintained by the Trustee, in
accordance with the transfer instructions set forth herein.  With respect to any
such transfer, the Trustee or the Custodian, at the direction of the Trustee,
shall cause, in accordance with the standing instructions and procedures
existing between the Depositary and the Custodian, the aggregate principal
amount of the global Note to be reduced by the principal amount of the
beneficial interest in the Note being transferred and, following such reduction,
the Company shall execute and the Trustee shall authenticate and make available
for delivery to the transferee (or such transferee's nominee, as the case may
be), a definitive Note or Notes in the appropriate aggregate principal amount in
the name of such transferee (or its nominee) and bearing such restrictive
legends as may be required by this Indenture.  As a


                                      17
<PAGE>

condition to such transfer, if such transfer is made to an Institutional 
Accredited Investor, the Trustee or the Custodian, at the direction of the 
transferor, shall be provided with such representations and agreements 
relating to the restrictions on transfer of such Note or Notes from such 
transferee (or such transferee's nominee) substantially in the form as set 
forth in Exhibit D hereto and as the Trustee (or the Custodian) may otherwise 
reasonably require.

         Any transfer of a definitive Note or Notes must be effected by the
delivery to the transferee (or its nominee) of a definitive Note or Notes
registered in the name of the transferee (or its nominee) on the books
maintained by the Trustee.  With respect to any such transfer, the Company shall
execute and the Trustee shall authenticate and make available for delivery to
the transferee (or such transferee's nominee, as the case may be), a definitive
Note or Notes in the appropriate aggregate principal amount in the name of such
transferee (or its nominee) and bearing such restrictive legends as may be
required by this Indenture.  As a condition to such transfer, if such transfer
is made to an Institutional Accredited Investor, the Trustee or the Custodian,
at the direction of the transferor shall be provided with such representations
and agreements relating to the restrictions on transfer of such Note or Notes
from such transferee (or such transferee's nominee) substantially in the form as
set forth in Exhibit D hereto.

         So long as the Notes are eligible for book-entry settlement, or unless
otherwise required by law, upon any transfer of a definitive Note to a QIB in
accordance with Rule 144A, unless otherwise requested by the transferor, and
upon receipt of the definitive Note or Notes being so transferred, together with
a certificate in the form of Exhibit E hereto from the transferor that the
transferor reasonably believes the transferee is a QIB and is obtaining such
beneficial interest in a transaction meeting the requirements of Rule 144A and
any applicable securities laws of any state of the United States or any other
jurisdiction (or other evidence satisfactory to the Trustee), the Trustee shall
cancel such definitive Note or Notes and cause, or direct the Custodian to
cause, in accordance with the standing instructions and procedures existing
between the Depositary and the Custodian, the aggregate principal amount of
Notes represented by the Restricted Global Note to be increased accordingly.

         So long as the Notes are eligible for book-entry settlement, or unless
otherwise required by law, upon any transfer of a definitive Note in accordance
with Regulation S, if requested by the transferor, and upon receipt of the
definitive Note or Notes being so transferred, together with a certificate in
the form of Exhibit F hereto from the transferor that the


                                      18
<PAGE>

transfer was made in accordance with Rule 903 or 904 of Regulation S under 
the Securities Act (or other evidence satisfactory to the Trustee), the 
Trustee shall cancel such definitive Note or Notes and cause, or direct the 
Custodian to cause, in accordance with the standing instructions and 
procedures existing between the Depositary and the Custodian, the aggregate 
principal amount of Notes represented by the Regulation S Global Note to be 
increased accordingly.

         If a holder of a beneficial interest in the Restricted Global Note
wishes at any time to exchange its interest in the Restricted Global Note for an
interest in the Regulation S Global Note, or to transfer its interest in the
Restricted Global Note to a person who wishes to take delivery thereof in the
form of an interest in the Regulation S Global Note, whether before or after the
expiration of the Restricted Period, such holder may, subject to the rules and
procedures of the Depositary and to the requirements set forth in the following
sentence, exchange or cause the exchange or transfer or cause the transfer of
such interest for an equivalent beneficial interest in the Regulation S Global
Note.  Upon receipt by the Trustee, as transfer agent, of (1) written
instructions given in accordance with the Depositary's procedures from or on
behalf of a holder of a beneficial interest in the Restricted Global Note,
directing the Trustee (via DWAC), as transfer agent, to credit or cause to be
credited a beneficial interest in the Regulation S Global Note in an amount
equal to the beneficial interest in the Restricted Global Note to be exchanged
or transferred, (2) a written order given in accordance with the Depositary's
procedures containing information regarding the Euroclear or Cedel account to be
credited with such increase and the name of such account, and (3) a certificate
in the form of Exhibit G given by the holder of such beneficial interest stating
that the exchange or transfer of such interest has been made pursuant to and in
accordance with Rule 903 or Rule 904 of Regulation S under the Securities Act
and that if such transfer occurs prior to the expiration of the Restricted
Period, the interest transferred will be held immediately thereafter, until the
expiration of the Restricted Period, through Euroclear or Cedel (or other
evidence satisfactory to the Trustee), the Trustee, as transfer agent, shall
promptly deliver appropriate instructions to the Depositary (via DWAC), its
nominee, or the custodian for the Depositary, as the case may be, to reduce or
reflect on its records a reduction of the Restricted Global Note by the
aggregate principal amount of the beneficial interest in such Restricted Global
Note to be so exchanged or transferred from the relevant participant, and the
Trustee, as transfer agent, shall promptly deliver appropriate instructions (via
DWAC) to the Depositary, its nominee, or the custodian for the Depositary, as
the case may be, concurrently with such reduction, to increase or reflect on its
records an increase of the principal amount of such Regulation S Global Note


                                      19
<PAGE>

by the aggregate principal amount of the beneficial interest in such 
Restricted Global Note to be so exchanged or transferred, and to credit or 
cause to be credited to the account of the person specified in such 
instructions (who shall be Morgan Guaranty Trust Company of New York, 
Brussels office, as operator of Euroclear or Cedel or another agent member of 
Euroclear or Cedel, or both, as the case may be, acting for and on behalf of 
them) a beneficial interest in such Regulation S Global Note equal to the 
reduction in the principal amount of such Restricted Global Note.

         Prior to the expiration of the Restricted Period, a beneficial
interest in the Regulation S Global Note may be transferred to a person who
takes delivery in the form of a beneficial interest in the Restricted Global
Note, subject to the rules and procedures of Euroclear or Cedel and the
Depositary, as the case may be, and to the requirements set forth in the
following sentence.  Upon receipt by the Trustee, as transfer agent, from the
transferror of (1) written instructions given in accordance with the procedures
of Euroclear or Cedel and the Depositary, as the case may be, from or on behalf
of a beneficial owner of an interest in the Regulation S Global Note directing
the Trustee, as transfer agent, to credit or cause to be credited a beneficial
interest in the Restricted Global Note in an amount equal to the beneficial
interest in the Regulation S Global Note to be exchanged or transferred, (2) a
written order given in accordance with the procedures of Euroclear or Cedel and
the Depositary, as the case may be, containing information regarding the account
with the Depositary to be credited with such increase and the name of such
account, and (3) prior to the expiration of the Restricted Period, a certificate
in the form of Exhibit H given by the holder of such beneficial interest and
stating that such transfer is being made to a person who the transferor
reasonably believes is purchasing for its own account or accounts as to which it
exercises sole investment discretion and that such person and each such account
is a QIB in each case and is obtaining such beneficial interest in a transaction
meeting the requirements of Rule 144A and any applicable securities laws of any
state of the United States or any other jurisdiction (or other evidence
satisfactory to the Trustee), the Trustee, as transfer agent, shall promptly
deliver (via DWAC) appropriate instructions to the Depositary, its nominee, or
the custodian for the Depositary, as the case may be, to reduce or reflect on
its records a reduction of the Regulation S Global Note by the aggregate
principal amount of the beneficial interest in such Regulation S Global Note to
be exchanged or transferred, and the Trustee, as transfer agent, shall promptly
deliver (via DWAC) appropriate instructions to the Depositary, its nominee, or
the custodian for the Depositary, as the case may be, concurrently with such
reduction, to increase or reflect on its records an increase of the principal
amount of the Restricted Global Note by


                                      20
<PAGE>

the aggregate principal amount of the beneficial interest in the Regulation S 
Global Note to be so exchanged or transferred, and to credit or cause to be 
credited to the account of the person specified in such instructions a 
beneficial interest in the Restricted Global Note equal to the reduction in 
the principal amount of the Regulation S Global Note.  After the expiration 
of the Restricted Period, the certification requirement set forth in clause 
(3) of the second sentence of this paragraph shall no longer apply to such 
exchanges and transfers.

         If a holder of a definitive Note wishes at any time to exchange its
Note for a beneficial interest in any global Note (or vice versa), or to
transfer its definitive Note to a person who wishes to take delivery thereof in
the form of a beneficial interest in a global Note (or vice versa), such Notes
and beneficial interests may be exchanged or transferred for one another only in
accordance with such procedures as are consistent with the provisions of this
Section 2.2(c) (including the certification requirements intended to ensure that
such exchanges or transfers comply with Rule 144, Rule 144A or Regulation S, as
the case may be) and as may be from time to time adopted by the Company with
notice to and the consent of the Trustee.  Such Notes shall bear the legends
required by Sections 2.5(c) and (d) as applicable.

         Any beneficial interest in one of the global Notes that is transferred
to a person who takes delivery in the form of an interest in the other global
Note shall, upon transfer, cease to be an interest in such global Note and
become an interest in the other global Note and, accordingly, shall thereafter
be subject to all transfer restrictions and other procedures applicable to
beneficial interests in such other global Note for as long as it remains such an
interest.

         Any global Note may be endorsed with or have incorporated in the text
thereof such legends or recitals or changes not inconsistent with the provisions
of this Indenture as may be required by the Company with notice thereof to the
Custodian, the Depositary or by the National Association of Securities Dealers,
Inc. in order for the Notes to be tradeable on the PORTAL Market or as may be
required for the Notes to be tradeable on any market developed for trading of
securities pursuant to Rule 144A or required to comply with any applicable law
or any regulation thereunder or with Regulation S or with the rules and
regulations of any securities exchange upon which the Notes may be listed or
traded or to conform with any usage with respect thereto, or to indicate any
special limitations or restrictions to which any particular Notes are subject.

         (c)  Every Note that bears or is required under this Section 2.5(c) to
bear the legend set forth in this Section 


                                      21

<PAGE>

2.5(c) (together with any Common Stock issued upon conversion of the Notes 
and required to bear the legend set forth in Section 2.5(d), collectively, 
the "Restricted Securities") shall be subject to the restrictions on transfer 
set forth in this Section 2.5(c), unless such restrictions on transfer shall 
have been waived by the written consent of the Company or removed in 
accordance with the provisions of Section 2.5(e), and the holder of each such 
Restricted Security, by such holder's acceptance thereof, agrees to be bound 
by such restrictions on transfer.  As used in this Section 2.5(c), the term 
"transfer" encompasses any sale, pledge, transfer or other disposition of any 
Restricted Security.

         Until three years after the later of the original issuance date of any
Note and the last date on which the Company or an Affiliate of the Company was
the owner of such Note, any certificate evidencing such Note (and all securities
issued in exchange therefor or substitution thereof, other than Common Stock, if
any, issued upon conversion thereof, which shall bear the legend set forth in
Section 2.5(d), if applicable) shall bear a legend in substantially the
following form, unless otherwise agreed by the Company (with notice thereof to
the Trustee):

    THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES
    ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES
    LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR
    THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE
    FOLLOWING SENTENCE.  BY ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT
    (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER
    THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS
    DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT)
    ("INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S. PERSON AND IS
    ACQUIRING THE NOTE EVIDENCED HEREBY IN AN OFFSHORE TRANSACTION; (2) AGREES
    THAT IT WILL NOT PRIOR TO THE DATE THAT IS THREE YEARS AFTER THE LATER OF
    THE ORIGINAL ISSUANCE OF THE NOTE EVIDENCED HEREBY AND THE LAST DATE ON
    WHICH PENN TREATY AMERICAN CORPORATION (THE "COMPANY") OR ANY "AFFILIATE"
    (AS DEFINED IN RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY WAS THE
    OWNER OF THE NOTE (THE "RESTRICTION TERMINATION DATE") RESELL OR OTHERWISE
    TRANSFER THE NOTE EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON
    CONVERSION OF SUCH NOTE EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY
    THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE
    144A UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL ACCREDITED INVESTOR
    THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO FIRST UNION NATIONAL BANK, AS
    TRUSTEE, A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS
    RELATING TO THE RESTRICTIONS ON TRANSFER OF THE NOTE EVIDENCED HEREBY (THE
    FORM OF WHICH LETTER CAN BE 


                                      22

<PAGE>

    OBTAINED FROM SUCH TRUSTEE), (D) OUTSIDE THE UNITED STATES IN COMPLIANCE 
    WITH RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (E) 
    PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER 
    THE SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO A REGISTRATION 
    STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT; 
    AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE NOTE 
    EVIDENCED HEREBY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF 
    THIS LEGEND.  IN CONNECTION WITH ANY TRANSFER OF THE NOTE EVIDENCED 
    HEREBY BEFORE THE RESTRICTION TERMINATION DATE, THE HOLDER MUST CHECK 
    THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE 
    MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO FIRST UNION 
    NATIONAL BANK, AS TRUSTEE.  IF THE PROPOSED TRANSFER IS PURSUANT TO 
    CLAUSE (C), (D) OR (E) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, 
    FURNISH TO FIRST UNION NATIONAL BANK, AS TRUSTEE, SUCH CERTIFICATIONS, 
    LEGAL OPINIONS OR OTHER INFORMATION AS THE COMPANY MAY REASONABLY 
    REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN 
    EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION 
    REQUIREMENTS OF THE SECURITIES ACT.  THIS LEGEND WILL BE REMOVED UPON 
    THE RESTRICTION TERMINATION DATE.  AS USED HEREIN, THE TERMS "OFFSHORE 
    TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN 
    TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         Any Note (or security issued in exchange or substitution therefor) as
to which such restrictions on transfer shall have expired in accordance with
their terms may, upon satisfaction of the requirements of Section 2.5(f) and
surrender of such Note for exchange to the Note registrar in accordance with the
provisions of this Section 2.5, be exchanged for a new Note or Notes, of like
tenor and aggregate principal amount, which shall not bear the restrictive
legend required by this Section 2.5(c).

         Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in this Section 2.5(c)), a global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary
or by a nominee of the Depositary to the Depositary or another nominee of the
Depositary or by the Depositary or any such nominee to a successor Depositary or
a nominee of such successor Depositary.

         The Depositary shall be a clearing agency registered under the
Exchange Act.  The Company initially appoints The Depository Trust Company to
act as Depositary with respect to the global Notes.  Initially, the global Notes
shall be issued to the Depositary, registered in the name of Cede, as the
nominee of the Depositary, and deposited with the Trustee as Custodian for Cede.


                                      23

<PAGE>

         Neither the Company nor the Trustee (or any registrar, paying agent or
conversion agent under this Indenture) shall have responsibility for the
performance by the Depositary and its nominees, Euroclear or Cedel Bank or their
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations.  The Depositary will take any
action permitted to be taken by a holder of Notes (including, without
limitation, the presentation of Notes for exchange as described below) only at
the direction of one or more participants to whose account with the Depositary
interests in the global Notes are credited, and only in respect of the principal
amount of the Notes represented by the global Notes as to which such participant
or participants has or have given such direction.

         If at any time the Depositary for the global Notes notifies the
Company that it is unwilling or unable to continue as Depositary for such Notes,
the Company may appoint a successor Depositary with respect to such Notes.  If a
successor Depositary for the Notes is not appointed by the Company within 90
days after the Company receives such notice, the Company shall execute, and the
Trustee, upon receipt of an Officers' Certificate for the authentication and
delivery of Notes, shall authenticate and make available for delivery, Notes in
definitive form, in an aggregate principal amount equal to the principal amount
of the global Notes in exchange for such global Notes.

         Definitive Notes issued in exchange for all or a part of a global Note
pursuant to this Section 2.5(c) shall be registered in such names and in such
authorized denominations as the Depositary, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee.  Upon
execution and authentication, the Trustee shall make available for delivery such
definitive Notes to the persons in whose names such definitive Notes are so
registered.

         At such time as all interests in global Notes have been redeemed,
converted, repurchased or canceled, such global Notes shall be, upon receipt
thereof, canceled by the Trustee in accordance with standing procedures and
instructions existing between the Depositary and the Custodian.  At any time
prior to such cancellation, if any interest in a global Note is exchanged for
definitive Notes, redeemed, repurchased, converted, canceled or transferred to a
transferee who receives definitive Notes therefor or any definitive Note is
exchanged or transferred for part of a global Note, the principal amount of such
global Note shall, in accordance with the standing procedures and instructions
existing between the Depositary and the Custodian, be reduced or increased, as
the case may be, and an endorsement shall be made on such global Note by the
Trustee or the 


                                      24

<PAGE>

Custodian, at the direction of the Trustee, to reflect such reduction or 
increase.

         The Company and the Trustee may for all purposes, including the making
of payments due on the Notes, deal with the Depositary as the authorized
representative of the Noteholders for the purposes of exercising the rights of
Noteholders hereunder.  The rights of the owner of any beneficial interest in a
global Note shall be limited to those established by law and agreements between
such owners and depository participants or Euroclear and Cedel; provided that no
such agreement shall give any rights to any person against the Company or the
Trustee without the written consent of the parties so affected.  Multiple
requests and directions from and votes of, the Depositary as holder of notes in
book entry form with respect to any particular matter shall not be deemed
inconsistent to the extent they do not represent an amount of notes in excess of
those held in the name of the Depositary or its nominee.

         (d)  Until three years after the later of the original issuance date
of any Note (other than any Note represented by the Regulation S Global Note)
and the last date on which the Company or an Affiliate of the Company was the
owner of such Note, any stock certificate representing Common Stock issued upon
conversion of such Note shall bear a legend in substantially the following form,
unless otherwise agreed by the Company (with written notice thereof to the
Trustee and any transfer agent for the Common Stock):

    THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
    SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
    SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR
    TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN
    THE FOLLOWING SENTENCE.  THE HOLDER HEREOF AGREES THAT PRIOR TO THE DATE
    THAT IS THREE YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE OF THE NOTE
    UPON THE CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS ISSUED
    AND THE LAST DATE ON WHICH PENN TREATY AMERICAN CORPORATION (THE "COMPANY")
    OR ANY "AFFILIATE" (AS DEFINED IN RULE 144 OF THE SECURITIES ACT) OF THE
    COMPANY WAS THE OWNER OF THE NOTE UPON THE CONVERSION OF WHICH THE COMMON
    STOCK EVIDENCED HEREBY WAS ISSUED OR THE COMMON STOCK EVIDENCED HEREBY (THE
    "RESTRICTION TERMINATION DATE"), (1) IT WILL NOT RESELL OR OTHERWISE
    TRANSFER THE COMMON STOCK EVIDENCED HEREBY EXCEPT (A) TO THE COMPANY OR ANY
    SUBSIDIARY THEREOF, (B) TO A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
    RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE 144A, (C) TO AN
    INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3)
    OR (7) UNDER THE SECURITIES ACT) THAT PRIOR TO SUCH TRANSFER, FURNISHES TO
    THE COMPANY'S 


                                      25

<PAGE>

    TRANSFER AGENT FOR ITS COMMON STOCK, A SIGNED LETTER CONTAINING CERTAIN 
    REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER 
    OF THE COMMON STOCK EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE 
    OBTAINED FROM SUCH TRANSFER AGENT), (D) OUTSIDE THE UNITED STATES IN 
    COMPLIANCE WITH RULE 903 OR 904 OF REGULATION S UNDER THE SECURITIES 
    ACT, (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 
    144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO A 
    REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE 
    SECURITIES ACT; (2) PRIOR TO ANY SUCH TRANSFER PURSUANT TO CLAUSE (C), 
    (D) OR (E) ABOVE, IT WILL FURNISH TO THE COMPANY'S TRANSFER AGENT FOR 
    COMMON STOCK, SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION 
    AS THE COMPANY MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS 
    BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT 
    SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (3) 
    IT WILL DELIVER TO EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY 
    IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  
    THIS LEGEND WILL BE REMOVED UPON THE SATISFACTION OF THE TRANSFER AGENT 
    THAT THE COMMON STOCK EVIDENCED HEREBY HAS BEEN OR IS BEING OFFERED AND 
    SOLD PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR IN ACCORDANCE 
    WITH RULE 144 OR RULE 903 OR RULE 904 OF REGULATION S UNDER THE 
    SECURITIES ACT.  AS USED HEREIN, THE TERMS "UNITED STATES" AND "U.S. 
    PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE 
    SECURITIES ACT.

         Any such Common Stock as to which such restrictions on transfer shall
have expired in accordance with their terms may, upon satisfaction of the
requirements of Section 2.5(f) and surrender of the certificates representing
such shares of Common Stock for exchange in accordance with the procedures of
the transfer agent for the Common Stock, be exchanged for a new certificate or
certificates for a like aggregate number of shares of Common Stock, which shall
not bear the restrictive legend required by this Section 2.5(d).

         (e)  Upon any sale or transfer of any Restricted Security (including
any interest in a global Note) (i) that is effected pursuant to an effective
registration statement under the Securities Act, (ii) that is effected pursuant
to Rule 144 as promulgated under the Securities Act as determined by counsel to
the Company or (iii) in connection with which the Trustee (or transfer agent for
the Common Stock, in the case of shares of Common Stock) receives certificates
and other information (including an opinion of counsel, if requested) reasonably
acceptable to the Company to the effect that such security shall no longer be
subject to the resale restrictions under federal and state securities laws, then
(A) in the case of a Restricted Security in definitive form, the Note registrar
or co-registrar 


                                      26

<PAGE>

(or transfer agent, in the case of Common Stock) shall permit the holder 
thereof to exchange such Restricted Security for a security that does not 
bear the legends set forth in Section 2.5(c) or 2.5(d), as applicable, and 
shall rescind any such restrictions on transfer and (B) in the case of 
Restricted Securities represented by a global Note, such Note shall no longer 
be subject to the restrictions contained in the legend set forth in Section 
2.5(c) (but still subject to the other provisions hereof).  In addition, any 
Note (or security issued in exchange or substitution therefor) or shares of 
Common Stock issued upon conversion of any Note, in either case, as to which 
the restrictions on transfer described in the legends set forth in Section 
2.5(c) and 2.5(d), respectively, have expired by their terms, may, upon 
surrender thereof (in accordance with the terms of this Indenture in the case 
of Notes) together with such certifications and other information (including 
an opinion of counsel having substantial experience in practice under the 
Securities Act and otherwise reasonably acceptable to the Company, addressed 
to the Company and the Trustee and in a form acceptable to the Company, to 
the effect that the transfer of such Restricted Security has been made in 
compliance with Rule 144 or such successor provision) acceptable to the 
Company be exchanged for a new Note or Notes of like tenor and aggregate 
principal amount (in the case of Notes), or a new certificate or certificates 
for a like aggregate number of shares of Common Stock (in the case of Common 
Stock), or a new certificate or other instrument of like tenor and amount (in 
the case of securities issued in exchange or substitution for Notes), which 
shall not bear the restrictive legends set forth in Sections 2.5(c) and 
2.5(d).

         (f)  Each holder or former holder of a Note agrees to indemnify the
Company and the Trustee against any liability that may result from the transfer,
exchange or assignment of such holder's or former holder's Note in violation of
any provision of this Indenture and/or applicable U.S. federal or state
securities law.

         Section 2.6  MUTILATED, DESTROYED, LOST OR STOLEN NOTES.  In case 
any Note shall become mutilated or be destroyed, lost or stolen, the Company 
in its discretion may execute, and upon its request, the Trustee or an 
authenticating agent appointed by the Trustee shall authenticate and make 
available for delivery a new Note bearing a number not contemporaneously 
outstanding in exchange and substitution for the mutilated Note or in lieu of 
and in substitution for the Note so destroyed, lost or stolen.  The Company 
may charge such applicant for the expenses of the Company in replacing a 
Note.  In every case the applicant for a substituted Note shall furnish to 
the Company, to the Trustee and, if applicable, to such authenticating agent 
such security or indemnity as may be required by them to save each of them 
harmless from any loss, liability, cost or expense caused by 


                                      27

<PAGE>

or connected with such substitution, and in every case of destruction, loss 
or theft, the applicant shall also furnish to the Company, to the Trustee 
and, if applicable, to such authenticating agent evidence to their 
satisfaction of the destruction, loss or theft of such Note and of the 
ownership thereof.

         The Trustee or such authenticating agent may authenticate any such
substituted Note and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may require.  Upon the issuance of any substituted Note, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses connected
therewith.  In case any Note that has matured or is about to mature or has been
called for redemption or is about to be repurchased or converted into Common
Stock or cash shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a substitute Note, pay or authorize the payment
of or convert or authorize the conversion of the same (without surrender
thereof, except in the case of a mutilated Note), as the case may be, if the
applicant for such payment or conversion shall furnish to the Company, to the
Trustee and, if applicable, to such authenticating agent such security or
indemnity as may be required by them to save each of them harmless from any
loss, liability, cost or expense caused by or connected with such substitution,
and in case of destruction, loss or theft, evidence satisfactory to the Company,
the Trustee and, if applicable, any paying agent or conversion agent of the
destruction, loss or theft of such Note and of the ownership thereof.

         Every substitute Note issued pursuant to the provisions of this
Section 2.6 in lieu of any Note that is destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not
the destroyed, lost or stolen Note shall be enforceable by anyone, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other
Notes duly issued hereunder.  To the extent permitted by law, all Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment or conversion of mutilated,
destroyed, lost or stolen Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment or conversion of negotiable
instruments or other securities without their surrender.

         Section 2.7  TEMPORARY NOTES.  Pending the preparation of definitive
Notes, the Company may execute and the Trustee or 


                                      28

<PAGE>

an authenticating agent appointed by the Trustee shall, upon written request 
of the Company, authenticate and make available for delivery temporary Notes 
(printed or lithographed).  Temporary Notes shall be issuable in any 
authorized denomination and shall be substantially in the form of the 
definitive Notes but with such omissions, insertions and variations as may be 
appropriate for temporary Notes, all as may be determined by the Company.  
Every such temporary Note shall be executed by the Company and authenticated 
by the Trustee or such authenticating agent upon the same conditions and in 
substantially the same manner, and with the same effect, as the definitive 
Notes.  Without unreasonable delay the Company shall execute and deliver to 
the Trustee or such authenticating agent definitive Notes (other than in the 
case of Notes in global form) and thereupon any or all temporary Notes (other 
than any such global Note) may be surrendered in exchange therefor, at each 
office or agency maintained by the Company pursuant to Section 4.2 and the 
Trustee or such authenticating agent shall authenticate and make available 
for delivery in exchange for such temporary Notes an equal aggregate 
principal amount of definitive Notes.  Such exchange shall be made by the 
Company at its own expense and without any charge therefor. Until so 
exchanged, the temporary Notes shall in all respects be entitled to the same 
benefits and subject to the same limitations under this Indenture as 
definitive Notes authenticated and delivered hereunder.

         Section 2.8  CANCELLATION OF NOTES PAID, ETC.  All Notes surrendered
for the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer shall, if surrendered to the Company or any paying
agent or any Note registrar or any conversion agent, be surrendered to the
Trustee and promptly canceled by it or, if surrendered to the Trustee, shall be
promptly canceled by it and no Notes shall be issued in lieu thereof except as
expressly permitted by any of the provisions of this Indenture.  If required by
the Company, the Trustee shall return canceled Notes to the Company.  If the
Company shall acquire any of the Notes, such acquisition shall not operate as a
redemption or satisfaction of the indebtedness represented by such Notes unless
and until the same are delivered to the Trustee for cancellation.

         Section 2.9  CUSIP NUMBERS.  The Company in issuing the Notes may use
"CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use
CUSIP numbers in notices of redemption as a convenience to holders; provided
that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, and any such redemption shall not
be affected by any defect in or


                                      29
<PAGE>

omission of such numbers.  The Company shall promptly notify the Trustee of 
any change in the CUSIP numbers.

declining redemption prices set forth below plus accrued and unpaid interest
thereon to the applicable redemption date if redeemed during the twelve-month

         Section 3.2  NOTICE OF REDEMPTION; SELECTION OF NOTES.  In case the
Company shall desire to exercise the right to redeem all or, as the case may 
be, any part of the Notes pursuant to Section 3.1, it shall fix a date for
redemption and, in the case of any redemption pursuant to Section 3.1, it or, 
at its written request accompanied by the proposed form of notice of redemption
(which must be received by the Trustee at least ten days prior to the date the
Trustee is requested to give notice as described below, unless a shorter period
is agreed to by the Trustee), the Trustee in the name of and at the expense of
the Company, shall publish a notice in the Wall Street Journal and mail or 
cause to be mailed a notice of such redemption at least 30 and not more than 60
days prior to the date fixed for redemption to the holders of Notes so to be 
redeemed as a whole or in part at their last addresses as the same appear on 
the Note register, provided that subject to the approval of the form of notice 
by the Trustee if the Company shall give such notice, it shall also give such 
notice, and notice of the Notes to be redeemed, to the Trustee.  Such mailing 
shall be by first class mail.  The notice, if mailed in the manner herein 
provided, shall be conclusively presumed to have been duly given, whether or 
not the holder receives such notice.  In any case, failure to give such notice 
by mail or any defect in the notice to the holder of any Note designated for 
redemption as a whole or in part shall not affect the validity of the 
proceedings for the redemption of any other Note.


                                      30

<PAGE>

         Each such notice of redemption shall identify the Notes to be redeemed
(including CUSIP numbers), specify the aggregate principal amount of Notes to 
be redeemed, the date fixed for redemption, the redemption price at which Notes
are to be redeemed, the place or places of payment, that payment shall be made 
upon presentation and surrender of such Notes, that interest accrued to the 
date fixed for redemption shall be paid as specified in said notice and that on
and after said date, interest thereon or on the portion thereof to be 
redeemed shall cease to accrue.  Such notice shall also state the current 
Conversion Price and the date on which the right to convert such Notes or 
portions thereof into Common Stock shall expire.  If fewer than all the Notes 
are to be redeemed, the notice of redemption shall identify the Notes to be 
redeemed.  In case any Note is to be redeemed in part only, the notice of 
redemption shall state the portion of the principal amount thereof to be 
redeemed and shall state that on and after the date fixed for redemption, 
upon surrender of such Note, a new Note or Notes in principal amount equal to 
the unredeemed portion thereof shall be issued. 

         On or prior to the Business Day prior to the redemption date specified
in the notice of redemption given as provided in this Section 3.2, the Company
shall deposit with the Trustee or with one or more paying agents (or, if the
Company is acting as its own paying agent, set aside, segregate and hold in
trust as provided in Section 4.4) an amount of money sufficient to redeem on 
the redemption date all the Notes so called for redemption (other than those
theretofore surrendered for conversion into Common Stock or cash) at the
appropriate redemption price, together with accrued interest to the date fixed
for redemption.  If any Note called for redemption is converted pursuant 
hereto, any money deposited with the Trustee or any paying agent or so 
segregated and held in trust for the redemption of such Note shall be paid to 
the Company upon its written request or, if then held by the Company, shall 
be discharged from such trust.  If fewer than all the Notes are to be redeemed,
the Company shall give the Trustee written notice in the form of an Officers' 
Certificate not fewer than 45 days (or such shorter period of time as may be 
acceptable to the Trustee) prior to the redemption date as to the aggregate 
principal amount of Notes to be redeemed.

         If fewer than all the Notes are to be redeemed, the Trustee shall
select the Notes or portions thereof to be redeemed (in principal amounts of
$1,000 or integral multiples thereof), by lot or, in its discretion, on a PRO
RATA basis.  If any Note selected for partial redemption is converted in part
after such selection, the converted portion of such Note shall be deemed (so 
far as may be) to be the portion to be selected for redemption.  The Notes (or
portions thereof) so selected shall be deemed duly


                                      31

<PAGE>

selected for redemption for all purposes hereof, notwithstanding that any 
such Note is converted as a whole or in part before the mailing of the notice 
of redemption. 

         Upon any redemption of less than all Notes, the Company and the
Trustee may treat as outstanding any Notes surrendered for conversion during 
the period of 15 days next preceding the mailing of a notice of redemption 
and need not treat as outstanding any Note authenticated and delivered during 
such period in exchange for the unconverted portion of any Note converted in 
part during such period.

         Section 3.3  PAYMENT OF NOTES CALLED FOR REDEMPTION.  If notice of
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date and at
the place or places stated in such notice at the applicable redemption price,
together with interest thereon accrued to the date fixed for redemption, and on
and after said date (unless the Company shall default in the payment of such
Notes at the redemption price, together with interest thereon accrued to said
date), interest on the Notes or portion of Notes so called for redemption shall
cease to accrue, and such Notes shall cease after the close of business on the
Business Day next preceding the date fixed for redemption to be convertible 
into Common Stock or cash and, except as provided in Sections 7.6 and 12.4, 
to be entitled to any benefit or security under this Indenture, and the holders
thereof shall have no right in respect of such Notes except the right to 
receive the redemption price thereof and unpaid interest thereon to the date 
fixed for redemption.  On presentation and surrender of such Notes at a place 
of payment in said notice specified, the said Notes or the specified portions 
thereof shall be paid and redeemed by the Company at the applicable 
redemption price, together with interest accrued thereon to the date fixed 
for redemption; provided that any semi-annual payment of interest becoming 
due on the date fixed for redemption shall be payable to the holders of such 
Notes registered as such on the relevant record date subject to the terms and 
provisions of Section 2.3 hereof.

         Upon presentation of any Note redeemed in part only, the Company shall
execute and the Trustee shall authenticate and make available for delivery to
the holder thereof, at the expense of the Company, a new Note or Notes, of
authorized denominations, in principal amount equal to the unredeemed portion 
of the Notes so presented.

         If any Note called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and premium, if any, shall, until paid or
duly provided for, bear interest


                                      32

<PAGE>

from the date fixed for redemption at the rate borne by the Note and such 
Note shall remain convertible into Common Stock  until the principal and 
premium, if any, shall have been paid or duly provided for.

         Section 3.4  CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.  In
connection with any redemption of Notes, with notice to the Trustee, the 
Company may arrange for the purchase and conversion of any Notes by an 
agreement with one or more investment bankers or other purchasers to purchase 
such Notes by paying to the Trustee in trust for the Noteholders, on or prior 
to the close of business one Business Day prior to the date fixed for 
redemption, an amount not less than the applicable redemption price, together 
with interest accrued to the date fixed for redemption, of such Notes.  
Notwithstanding anything to the contrary contained in this Article III, the 
obligation of the Company to pay the redemption price of such Notes, together 
with interest accrued to the date fixed for redemption, shall be deemed to be 
satisfied and discharged to the extent such amount is so paid by such 
purchasers.  If such an agreement is entered into, a copy of which shall be 
filed with the Trustee prior to the date fixed for redemption, any Notes not 
duly surrendered for conversion by the holders thereof may, at the option of 
the Company, be deemed, to the fullest extent permitted by law, acquired by 
such purchasers from such holders and (notwithstanding anything to the 
contrary contained in Article XIV) surrendered by such purchasers for 
conversion, prior to the close of business on the date fixed for redemption 
(and the right to convert any such Notes shall be deemed to have been 
extended through such time), subject to payment of the above amount as 
aforesaid.  At the direction of the Company, the Trustee shall hold and 
dispose of any such amount paid to it in the same manner as it would monies 
deposited with it by the Company for the redemption of Notes.  Without the 
Trustee's prior written consent, no arrangement between the Company and such 
purchasers for the purchase and conversion of any Notes shall increase or 
otherwise affect any of the powers, duties, responsibilities or obligations 
of the Trustee as set forth in this Indenture, and the Company agrees to 
indemnify the Trustee from, and hold it harmless against, any loss, liability 
or expense arising out of or in connection with any such arrangement for the 
purchase and conversion of any Notes between the Company and such purchasers 
including the costs and expenses incurred by the Trustee in the defense of 
any claim or liability arising out of or in connection with the exercise or 
performance of any of its powers, duties, responsibilities or obligations 
under this Indenture. 

         Section 3.5  REPURCHASE OF NOTES UPON A CHANGE OF CONTROL.


                                      33

<PAGE>

         (a)  If a Change of Control shall occur at any time, then each holder
of Notes shall have the right to require that the Company repurchase such
holder's Notes in whole or in part in integral multiples of $1,000 at a 
purchase price (the "Change of Control Purchase Price") in cash in an amount 
equal to 101% of the principal amount of such Notes, plus accrued and unpaid 
interest thereon, if any, to the purchase date (the "Change of Control 
Purchase Date") pursuant to the offer described below (the "Change of Control 
Offer") and in accordance with the other procedures set forth in this 
Indenture.

         (b)  Within 30 days following any Change of Control, the Company shall
publish a notice in the Wall Street Journal, notify the Trustee thereof and 
give written notice of such Change of Control to each holder of Notes, by 
first-class mail, postage prepaid, at the Noteholder's address appearing in 
the Note register, stating, among other things, (i) that a Change of Control 
has occurred, (ii) the Change of Control Purchase Price, (iii) the Change of 
Control Purchase Date (which shall be a Business Day no earlier than 30 days 
nor later than 60 days from the date such notice is mailed, or such later 
date as is necessary to comply with requirements under the Exchange Act), 
(iv) that any Note not tendered shall continue to accrue interest and to have 
all of the benefits of this Indenture, (v) that, unless the Company defaults 
in the payment of the Change of Control Purchase Price, any Notes accepted 
for payment pursuant to the Change of Control Offer shall cease to accrue 
interest after the Change of Control Purchase Date, (vi) that Noteholders 
electing to have any Notes purchased pursuant to a Change of Control Offer 
shall be required to surrender the Notes, with the form entitled "Option of 
Noteholder to Elect Purchase" on the reverse of the Notes completed, to the 
Company at the address specified in the notice prior to the close of business 
on the third Business Day preceding the Change of Control Purchase Date, 
(vii) that Noteholders shall be entitled to withdraw their election if the 
Company receives, not later than the close of business on the second Business 
Day preceding the Change of Control Purchase Date, a telegram, telex, 
facsimile transmission or letter setting forth the name of the Noteholder, 
the principal amount of Notes delivered for purchase, and a statement that 
such Noteholder is withdrawing his election to have such Notes purchased, and 
(viii) that Noteholders whose Notes are being purchased only in part shall be 
issued new Notes equal in principal amount to the unpurchased portion of the 
Notes surrendered, which unpurchased portion must be equal to $1,000 in 
principal amount or an integral multiple thereof.  The Company shall comply 
with the requirements of Rule 13e-4 and 14e-1 under the Exchange Act and any 
other securities laws and regulations thereunder to the extent such laws and 
regulations are applicable in connection with the repurchase of the Notes in 
connection with a Change of Control. 


                                      34

<PAGE>

         (c)  On the Change of Control Purchase Date, the Company shall, to the
extent lawful, (i) accept for payment Notes or portions thereof tendered
pursuant to the Change of Control Offer, (ii) deposit with the Trustee an 
amount equal to the Change of Control Purchase Price in respect of all Notes or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating 
the Notes or portions thereof tendered to the Company.  The Trustee shall 
promptly mail to each Noteholder of Notes so accepted payment in an amount 
equal to the purchase price of such Notes, and the Trustee shall promptly 
authenticate and mail to each Noteholder a new Note equal in principal amount 
to any unpurchased portion of the Notes surrendered, if any; provided that 
each such new Note shall be in a principal amount of $1,000 or an integral 
multiple thereof.  The Company shall publicly announce the results of the 
Change of Control Offer on or as soon as practicable after the Change of 
Control Payment Date. 

         (d)  The term "Change in Control" shall mean an event or series of
events in which (i) any "person" or "group" (as such terms are used in Sections
13(d) and 14(d) of the Exchange Act) acquires "beneficial ownership" (as
determined in accordance with Rule 13d-3 under the Exchange Act), directly or
indirectly, of more than 50% of the total Voting Stock of the Company at an
Acquisition Price less than the conversion price then in effect with respect to
the Notes and (ii) the holders of the Common Stock receive consideration which
is not all or substantially all common stock that is (or upon consummation of 
or immediately following such event or events will be) listed on a United 
States national securities exchange or approved for quotation on the Nasdaq 
Stock Market or any similar United States system of automated dissemination of
quotations of securities' prices; provided, however, that any such person or
group shall not be deemed to be the beneficial owner of, or to beneficially 
own, any Voting Stock tendered in a tender offer until such tendered Voting 
Stock is accepted for purchase under the tender offer.

         (e)  "Voting Stock" means stock of the class or classes pursuant to
which the holders thereof have the general voting power under ordinary
circumstances to elect at least a majority of the board of directors, managers
or trustees of a corporation (irrespective whether or not at the time stock of
any other class or classes shall have or might have voting power by reason of
the happening of any contingency).

                         PARTICULAR COVENANTS OF THE COMPANY


         Section 4.1  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.  The Company
covenants and agrees that it shall duly and punctually pay or cause to be paid
the principal of and premium, if any, and interest on each of the Notes at the
places, at the respective times and in the manner provided herein and in the
Notes.  Each installment of interest on the Notes due on any semi-annual
interest payment date may be paid by mailing checks for the interest payable to
or upon the written order of the holders of Notes entitled thereto as they 
shall appear on the Note register; provided that, with respect to any holder of
Notes with an aggregate principal amount equal to or in excess of $5,000,000, 
at the request (such request to include appropriate wire instructions) of such 
holder in writing to the Trustee, interest on such holder's Notes shall be paid
by wire transfer in immediately available funds.  An installment of principal 
or interest shall be considered paid on the date due if the Trustee or paying 
agent (other than the Company, a Subsidiary of the Company or any Affiliate of 
any of them) holds on that date money designated for and sufficient to pay the
installment of principal or interest and is not prohibited from paying such
money to the holders of the Notes pursuant to the terms of this Indenture.

         Section 4.2  MAINTENANCE OF OFFICE OR AGENCY.  The Company shall
maintain in the Borough of Manhattan, The City of New York, an office or agency
where the Notes may be surrendered for registration of transfer or exchange or
for presentation for payment or for conversion, redemption or repurchase and
where notices and demands to or upon the Company in respect of the Notes and
this Indenture may be served.  The Company shall give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency.  If at any time the Company shall fail to maintain any such office or
agency or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in the Borough of Manhattan,
The City of New York, for such purposes.  The Company shall give prompt written
notice to the Trustee of any such designation or rescission and of any change 
in the location of any such other office or agency.


                                      36

<PAGE>

         The Company hereby initially designates the Trustee as paying agent,
Note registrar and conversion agent and the office of Corporate Trust
Administration of the Trustee in the Borough of Manhattan, The City of New York
or the office of Corporate Trust Administration of the Trustee located in
Philadelphia, Pennsylvania, as two such offices or agencies of the Company for
the purposes set forth in the first paragraph of this Section 4.2.

         So long as the Trustee is the Note registrar, the Trustee agrees to
mail, or cause to be mailed, the notices set forth in Section 7.11(a).

         Section 4.3  APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE.  The
Company, whenever necessary to avoid or fill a vacancy in the office of 
Trustee, shall appoint, in the manner provided in Section 7.11, a Trustee, so 
that there shall at all times be a Trustee hereunder.

         Section 4.4  PROVISIONS AS TO PAYING AGENT.

         (a)  If the Company shall appoint a paying agent other than the
Trustee, or if the Trustee shall appoint such a paying agent, the Company or 
the Trustee, as the case may be, shall cause such paying agent to execute and
deliver to the Trustee an instrument in which such agent shall agree with the
Trustee, subject to the provisions of this Section 4.4:

         (1)  that it shall hold all sums held by it as such agent for the
    payment of the principal of, premium, if any, or interest on the Notes
    (whether such sums have been paid to it by the Company or by any other
    obligor on the Notes) in trust for the benefit of the holders of the Notes;

         (2)  that it shall give the Trustee written notice of any failure by
    the Company (or by any other obligor on the Notes) to make any payment of
    the principal of, premium, if any, or interest on the Notes when the same
    shall be due and payable; and

         (3)  that at any time during the continuance of an Event of Default,
    upon request of the Trustee, it shall forthwith pay to the Trustee all sums
    so held in trust.

         The Company shall, before each due date of the principal of, premium,
if any, or interest on the Notes, deposit with the paying agent a sum 
sufficient to pay such principal, premium, if any, or interest, and (unless 
such paying agent is the Trustee) the Company shall promptly notify the Trustee
of any failure to take such action.


                                      37

<PAGE>

         (b)  If the Company shall act as its own paying agent, it shall, on or
before each due date of the principal of, premium, if any, or interest on the
Notes, set aside, segregate and hold in trust for the benefit of the holders of
the Notes a sum sufficient to pay such principal, premium, if any, or interest
so becoming due and shall notify the Trustee of any failure to take such action
and of any failure by the Company (or any other obligor under the Notes) to 
make any payment of the principal of, premium, if any, or interest on the 
Notes when the same shall become due and payable.

         (c)  Anything in this Section 4.4 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture, or for any other reason, pay or cause to be paid 
to the Trustee all sums held in trust by the Company or any paying agent 
hereunder as required by this Section 4.4, such sums to be held by the Trustee 
upon the trusts herein contained and upon such payment by the Company or any 
paying agent to the Trustee, the Company or such paying agent shall be released
from all further liability with respect to such sums.

         (d)  Anything in this Section 4.4 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 4.4 is subject to
Sections 12.3 and 12.4.

         Section 4.5  CORPORATE EXISTENCE.  Subject to Article XI, the Company
shall do or cause to be done all things necessary to preserve and keep in full
force and effect (i) its corporate existence, and the corporate, partnership or
other existence of any Subsidiary of the Company, in accordance with the
respective organizational documents (as the same may be amended from time to
time) of the Company or any such Subsidiary and (ii) the rights (charter and
statutory), licenses and franchises of the Company and its Subsidiaries;
provided that the Company shall not be required to preserve any such right,
license or franchise, or the corporate, partnership or other existence of any 
of its Subsidiaries if the Board of Directors shall determine that the 
preservation thereof is no longer desirable in the conduct of the business of 
the Company and its Subsidiaries, taken as a whole, and that the loss thereof 
is not materially adverse to the holders of the Notes.

         Section 4.6  RULE 144A INFORMATION REQUIREMENT.  During the three-year
period following the original issuance date of any Note and during the
three-year period following the last date on which the Company or an Affiliate
of the Company was the owner of any Note (or shares of Common Stock issued upon
conversion of any Note), if the Company is subject neither to Section 13 nor
Section 15(d) of the Exchange Act, the Company shall at the written request of
any holder or beneficial holder of such Note


                                      38

<PAGE>

(or shares of Common Stock issued upon conversion of Notes) provide to such 
holder or beneficial holder of such Note (or shares of Common Stock issued 
upon conversion of Notes) and any prospective transferee designated by such 
holder or beneficial holder of such Note (or shares of Common Stock issued 
upon conversion of Notes) such information, if any, required by Rule 
144A(d)(4) under the Securities Act (so long as such information is required 
to permit such transfer under Rule 144A). 

         Section 4.7  STAY, EXTENSION AND USURY LAWS.  The Company covenants
(to the extent that it may lawfully do so) that it shall not at any time insist
upon, plead or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law or other law that would prohibit or 
forgive the Company from paying all or any portion of the principal of or 
interest on the Notes as contemplated herein, wherever enacted, now or at any 
time hereafter in force, or that may affect the covenants or the performance of
this Indenture; and the Company (to the extent it may lawfully do so) hereby 
expressly waives all benefit or advantage of any such law, and covenants that 
it shall not, by resort to any such law, hinder, delay or impede the execution 
of any power herein granted to the Trustee, but shall suffer and permit the 
execution of every such power as though no such law has been enacted.

         Section 4.8  COMPLIANCE STATEMENT; NOTICE OF DEFAULTS 

         (a) The Company shall deliver to the Trustee within 120 days after the
end of each fiscal year of the Company an Officers' Certificate stating whether
or not to the best knowledge of the signers thereof the Company is in 
compliance (without regard to periods of grace or notice requirements) with 
all conditions and covenants under this Indenture, and if the Company shall 
not be in compliance, specifying such non-compliance and the nature and 
status thereof of which such signer may have knowledge.

         (b) The Company shall file with the Trustee written notice of the
occurrence of any default or Event of Default within ten days of its becoming
aware of any such default or Event of Default.

         4.9  LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
SUBSIDIARIES.  The Company shall not, and shall not permit any of its
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction on the
ability of any Subsidiary to (i) pay dividends or make any other distribution 
on its Capital Stock or with respect to any other interest or participation in,
or measured by, its profits, or pay any indebtedness owed to, the Company or a
Subsidiary of the Company,


                                      39

<PAGE>

(ii) make loans or advances to the Company or any Subsidiary of the Company, 
or (iii) transfer any of its properties or assets to the Company.

         Section 4.10  TAXES.  The Company shall pay or discharge or cause to
be paid or discharged, before the same shall become delinquent, (i) all taxes,
assessments and governmental charges (including withholding taxes and any
penalties, interest and additions to taxes) levied or imposed upon the Company
or its Subsidiaries or upon the income, profits or property of the Company or
any such Subsidiary and (ii) all lawful claims for labor, materials and 
supplies that, if unpaid, might by law become a lien upon the property of the 
Company or any such Subsidiary; provided that the Company shall not be required
to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in 
good faith by appropriate proceedings and for which disputed amounts adequate 
reserves have been made.

         Section 4.11  INSURANCE.  The Company shall provide, or cause to be
provided, for itself and its Subsidiaries, insurance (including appropriate
self-insurance) against loss or damage of the kinds customarily insured against
by corporations similarly situated and owning like properties, including, but

Directors to be appropriate.

                                     THE COMPANY


         Section 5.1  NOTEHOLDERS' LISTS.  The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to 
it of the names and addresses of holders of Notes, the Company and the Trustee,
and shall otherwise comply with Trust Indenture Act Section 312(a).  If the 
Trustee is not the Notes registrar, the Company shall furnish to the Trustee on
or before at least seven Business Days preceding each interest payment date and
at such other times as the Trustee may request in writing a list in such form 
and as of such date as the Trustee reasonably may require of the names and 
addresses of holders of Notes, and the Company shall otherwise comply with 
Trust Indenture Act Section 312(a).

     Section 5.2  REPORTS BY COMPANY.  The Company shall deliver to the Trustee
within 15 days after it files the same with the Commission, copies of all 
reports and information (or copies of such portions of any of the foregoing as 
the Commission may by its rules and regulations prescribe), if any, which the
Company is required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act or pursuant to the immediately following sentence.  So long
as at least $5,000,000 aggregate principal amount of Notes remain outstanding,
the Company shall file with the Commission such reports as may be required
pursuant to Section 13 of the Exchange Act in respect of a security registered
pursuant to Section 12 of the Exchange Act, regardless of whether the Company is
otherwise required to file such reports.  If the Company is not subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act (or otherwise
required to file reports pursuant to the immediately preceding sentence), the
Company shall deliver to the Trustee, within 15 days after it would have been
required to file such information with the Commission were it required to do so,
annual and quarterly financial statements, including any notes thereto (and, in
the case of a fiscal year end, an auditors' report by an independent certified
public accounting firm of established national reputation), and a "Management's
Discussion and Analysis of Financial Condition and Results of Operations," in
each case substantially equivalent to that which it would have been required to
include in such quarterly or annual reports, information, documents or other
reports if it had been subject to the requirements of Section 13 or 15(d) of the
Exchange Act.  The Company shall provide copies of the foregoing materials to
the Noteholders to the extent required by the Trust Indenture Act once this
Indenture has been qualified.  The Company shall also  comply with the other
provisions of the Trust Indenture Act Section 314(a).

     If the Company is not required to file the reports and information 
described above with the Commission, and the Company's Common Stock is still 
publicly held, the Company shall deliver an annual financial report for the 
Common Stock (as required by the Commission) to the Trustee no later than 120
days from the end of its fiscal year and quarterly financial reports for the
Common Stock (as required by the Commission) no later than 30 days after the 
end of each quarter; provided, however, that if the Company's Common Stock is no
longer publicly held, the Company shall deliver annual and quarterly reports to
the Trustee at the same times as described in this paragraph, but the Company
shall not have to include management's discussion and analysis of financial
conditions and results of operations or description of the business sections in
such reports.

     Delivery of such reports, information and documents to the Trustee is for 
informational purposes only and the Trustee's receipt of such shall not 
constitute constructive notice of any information contained therein or 
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).


                                      ARTICLE VI

                                DEFAULTS AND REMEDIES


     Section 6.1  EVENTS OF DEFAULT.  In case one or more of the following
Events of Default (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body) shall have occurred and be
continuing:

         (a) default in the payment of the principal of or premium, if any, on 
     the Notes when due at maturity, upon redemption or otherwise, including 
     failure by the Company to purchase the Notes when required under 
     Section 3.5 (whether or not such payment shall be prohibited by Article XV
     of this Indenture); or

         (b) default in the payment of any installment of interest on the Notes
      as and when the same shall become due and payable (whether or not such 
      payment shall be prohibited by Article XV of this Indenture), and 
      continuance of such default for a period of 30 days; or

         (c) a failure on the part of the Company to duly observe or perform any
     other covenants or agreements on the part of the Company in this Indenture 
     (other than a default in the performance or breach of a covenant or 
     agreement that is specifically dealt with elsewhere in this Section 6.1)
     that continues for a period of 90 days after the date on which written
     notice of such failure, requiring the Company to remedy the same, shall
     have been given to the Company by the Trustee, or to the Company and a
     Responsible Officer of the Trustee, by the holders of at least 25% in
     aggregate principal amount of the Notes at the time outstanding determined
     in accordance with Section 8.4; or

         (d) an event of default occurs under any mortgage, indenture or 
     instrument under which there may be issued or by which there may be secured
     or evidenced any indebtedness 


                                      42
<PAGE>

     for money borrowed by the Company or any of its Subsidiaries (or the 
     payment of which is guaranteed by the Company or any of its Subsidiaries),
     whether such indebtedness or guarantee now exists or shall be created after
     the date hereof, which default (i) is caused by a failure to pay principal
     or interest on such indebtedness prior to the expiration of the grace 
     period provided in such indebtedness (a "Payment Default") or (ii) results
     in the acceleration of such indebtedness prior to its expressed maturity 
     and, in each case, the principal amount of such indebtedness, together 
     with the principal amount of any other such indebtedness under which there
     has been a Payment Default or the maturity of which has been so 
     accelerated, aggregates $10 million or more;

         (e) final judgments or decrees shall be entered by a court of competent
    jurisdiction against the Company or any Subsidiary involving liabilities of 
    $10 million or more (singly or in the aggregate) (after deducting the 
    portion of such liabilities accepted by a reputable insurance company) and 
    such final judgments or decrees shall not have been vacated, discharged, 
    satisfied or stayed pending appeal within 60 days from the entry thereof;

         (f) the Company shall commence a voluntary case or other proceeding
    seeking liquidation, reorganization or other relief with respect to itself
    or its debts under any bankruptcy, insolvency or other similar law now or
    hereafter in effect, or seeking the appointment of a trustee, receiver,
    liquidator, custodian or other similar official of it or any substantial
    part of its property, or shall consent to any such relief or to the
    appointment of or taking possession by any such official in an involuntary
    case or other proceeding commenced against it or shall make a general
    assignment for the benefit of creditors or shall fail generally to pay its
    debts as they become due; or

         (g) an involuntary case or other proceeding shall be commenced
    against the Company seeking liquidation, reorganization or other relief
    with respect to it or its debts under any bankruptcy, insolvency or other
    similar law now or hereafter in effect or seeking the appointment of a
    trustee, receiver, liquidator, custodian or other similar official of it or
    any substantial part of its property, and such involuntary case or other
    proceeding shall remain undismissed and unstayed for a period of 60
    consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 6.1(f) or (g)), unless the principal of all of the Notes shall have
already become due and payable, 


                                      43
<PAGE>

either the Trustee or the holders of not less than 25% in aggregate principal 
amount of the Notes then outstanding hereunder determined in accordance with 
Section 8.4, by notice in writing to the Company (and to the Trustee if given
by Noteholders), may declare the principal of, premium, if any, on the Notes and
the interest accrued thereon to be due and payable immediately, and upon any 
such declaration the same shall become and shall be immediately due and payable,
anything in this Indenture or in the Notes contained to the contrary 
notwithstanding.  If an Event of Default specified in Section 6.1(f) or 
(g) occurs and is continuing, the principal of all the Notes and the interest 
accrued thereon shall be immediately due and payable.  The foregoing provision 
is subject to the conditions that if, at any time after the principal of the 
Notes shall have been so declared due and payable, and before any judgment or 
decree for the payment of the monies due shall have been obtained or entered as 
hereinafter provided, the Company shall pay or shall deposit with the Trustee a 
sum sufficient to pay all matured installments of interest upon all Notes and 
the principal of and premium, if any, on any and all Notes that shall have 
become due otherwise than by acceleration (with interest on overdue installments
of interest (to the extent that payment of such interest is enforceable under 
applicable law) and on such principal and premium, if any, at the rate borne by
the Notes, to the date of such payment or deposit) and amounts due to the 
Trustee pursuant to Section 7.7, and if any and all defaults under this 
Indenture, other than the nonpayment of principal of, premium, if any, and 
accrued interest on Notes that shall have become due by acceleration, shall 
have been cured or waived pursuant to Section 6.7, then and in every such case 
the holders of a majority in aggregate principal amount of the Notes then 
outstanding, by written notice to the Company and to the Trustee, may waive all
defaults or Events of Default and rescind and annul such declaration and its
consequences; but no such waiver or rescission and annulment shall extend to or
shall affect any subsequent default or Event of Default, or shall impair any
right consequent thereto.  The Company shall notify a Responsible Officer of the
Trustee, promptly upon becoming aware thereof, of any Event of Default.

     In case the Trustee shall have proceeded to enforce any right under this 
Indenture and such proceedings shall have been discontinued or abandoned 
because of such waiver or rescission and annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the holders of Notes and the Trustee shall be restored respectively
to their several positions and rights hereunder, and all rights, remedies and
powers of the Company, the holders of Notes and the Trustee shall continue as
though no such proceeding had been taken.

     Section 6.2  PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR.  The Company
covenants that (a) in case a default shall be made in the payment of any
installment of interest upon any of the Notes as and when the same shall become
due and payable, and such default shall have continued for a period of 30 days,
or (b) in case default shall be made in the payment of the principal of or
premium, if any, on any of the Notes as and when the same shall have become due
and payable, whether at maturity of the Notes or in connection with any
redemption or repurchase, by declaration or otherwise, then, upon demand of the
Trustee, the Company shall pay to the Trustee, for the benefit of the holders of
the Notes, the whole amount that then shall have become due and payable on all
such Notes for principal of, premium, if any, or interest, or both, as the case
may be, with interest upon the overdue principal, premium, if any, and (to the
extent that payment of such interest is enforceable under applicable law) upon
the overdue installments of interest at the rate borne by the Notes; and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including reasonable compensation to the Trustee,
its agents, attorneys and counsel, and any expenses or liabilities incurred by
the Trustee hereunder other than through its negligence or bad faith.  Until
such demand by the Trustee, the Company may pay the principal of and premium, if
any, and interest on the Notes to the registered holders, whether or not the
Notes are overdue.

     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes
and collect in the manner provided by law out of the property of the Company or
any other obligor on the Notes wherever situated the monies adjudged or decreed
to be payable.

     In case there shall be pending proceedings for the bankruptcy or for the 
reorganization of the Company or any other obligor on the Notes under Title 11 
of the United States Code or any other applicable law, or in case a receiver,
assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or
similar official shall have been appointed for or taken possession of the
Company or such other obligor, the property of the Company or such other
obligor, or in the case of any other judicial proceedings relative to the
Company or such other obligor upon the Notes, or to the creditors or property of
the Company or such other obligor, the Trustee, irrespective of whether the
principal of the Notes shall then be due and payable as therein expressed or by
declaration or otherwise and 


                                      45
<PAGE>

irrespective of whether the Trustee shall have made any demand pursuant to the 
provisions of this Section 6.2, shall be entitled and empowered, by intervention
in such proceedings or otherwise, to file and prove a claim or claims for the 
whole amount of principal, premium, if any, and interest owing and unpaid in 
respect of the Notes and, in case of any judicial proceedings, to file such 
proofs of claim and other papers or documents as may be necessary or advisable 
in order to have the claims of the Trustee and of the Noteholders allowed in 
such judicial proceedings relative to the Company or any other obligor on the 
Notes, its or their creditors, or its or their property and to collect and 
receive any monies or other property payable or deliverable on any such claims 
and to distribute the same after the deduction of any amounts due the Trustee 
under Section 7.7; and any receiver, assignee or trustee in bankruptcy or 
reorganization, liquidator, custodian or similar official is hereby authorized 
by each of the Noteholders to make such payments to the Trustee and, in the 
event that the Trustee shall consent to the making of such payments directly 
to the Noteholders, to pay to the Trustee any amount due it for reasonable 
compensation, expenses, advances and disbursements, including counsel fees 
incurred by it up to the date of such distribution.  To the extent that such 
payment of reasonable compensation, expenses, advances and disbursements out of
the estate in any such proceedings shall be denied for any reason, payment of 
the same shall be secured by a lien on, and shall be paid out of, any and all 
distributions, dividends, monies, securities and other property that the holders
of the Notes may be entitled to receive in such proceedings, whether in 
liquidation or under any plan of reorganization or arrangement or otherwise.

    Nothing herein contained shall be deemed to authorize the Trustee to 
authorize or consent to or adopt on behalf of any Noteholder any plan of
reorganization or arrangement affecting the Notes or the rights of any
Noteholder, or to authorize the Trustee to vote in respect of the claim of any
Noteholder in any such proceeding.

    All rights of action and of asserting claims under this Indenture, or under
any of the Notes, may be enforced by the Trustee without the possession of any 
of the Notes or the production thereof on any trial or other proceeding relative
thereto, and any such suit or proceeding instituted by the Trustee shall be 
rought in its own name as trustee of an express trust, and any recovery of 
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be 
for the ratable benefit of the holders of the Notes.

    In any proceedings brought by the Trustee pursuant to this Indenture or any
supplement hereto (and in any proceedings 


                                      46
<PAGE>

involving the interpretation of any provision of this Indenture to which the 
Trustee shall be a party), the Trustee shall be held to represent all the 
holders of the Notes, and it shall not be necessary to make any holders of the 
Notes parties to any such proceedings.

     Section 6.3  APPLICATION OF MONIES COLLECTED BY TRUSTEE.  Any monies
collected by the Trustee pursuant to this Article VI shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid:

         First:  To the payment of all amounts due the Trustee under Section 
    7.7;

         Second:  Subject to the provisions of Article XV, in case the principal
    of the outstanding Notes shall not have become due and be unpaid, to the 
    payment of interest on the Notes in default in the order of the maturity of
    the installments of such interest, with interest (to the extent that such 
    interest has been collected by the Trustee) upon the overdue installments 
    of interest at the rate borne by the Notes, such payments to be made 
    ratably to the persons entitled thereto; and

         Third:  Subject to the provisions of Article XV, in case the principal
    of the outstanding Notes shall have become due, by declaration or
    otherwise, and be unpaid, to the payment of the whole amount then holding
    and unpaid upon the Notes for principal, premium, if any, and interest,
    with interest on the overdue principal and premium, if any, and (to the
    extent that such interest has been collected by the Trustee) upon overdue
    installments of interest at the rate borne by the Notes; and in case such
    monies shall be insufficient to pay in full the whole amounts so due and
    unpaid upon the Notes, then to the payment of such principal, premium, if
    any, and interest without preference or priority of principal and premium,
    if any, over interest, or of interest over principal and premium, if any,
    or of any installment of interest over any other installment of interest,
    or of any Note over any other Note, ratably to the aggregate of such
    principal and premium, if any, and accrued and unpaid interest.

    Section 6.4  PROCEEDINGS BY NOTEHOLDER.  No holder of any Note shall
have any right by virtue of or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture, or for the appointment of a receiver, trustee,


                                      47

<PAGE>

liquidator, custodian or other similar official, or for any other remedy 
hereunder, unless such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof, as hereinbefore
provided, and unless also the holders of not less than 25% in aggregate
principal amount of the Notes then outstanding shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby, and the Trustee for 60 days after its receipt of
such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding, and no direction inconsistent
with such written request shall have been given to the Trustee pursuant to
Section 6.7; it being understood and intended, and being expressly covenanted by
the taker and holder of every Note with every other taker and holder and the
Trustee, that no one or more holders of Notes shall have any right in any manner
whatever by virtue of or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any other holder of Notes, to obtain
or seek to obtain priority over or preference to any other such holder or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all holders of Notes (except as
otherwise provided herein).  For the protection and enforcement of this Section
6.4, each and every Noteholder and the Trustee shall be entitled to such relief
as can be given either at law or in equity.

    Notwithstanding any other provision of this Indenture and any provision of 
any Note, the right of any holder of any Note to receive payment of the 
principal of, premium, if any, and interest on such Note, on or after the 
respective due dates expressed in such Note, or to institute suit for the
enforcement of any such payment on or after such respective dates against the
Company shall not be impaired or affected without the consent of such holder
except as otherwise set forth herein.

    Anything in this Indenture or the Notes to the contrary notwithstanding, 
the holder of any Note, without the consent of either the Trustee or the holder
of any other Note, in his own behalf and for his own benefit, may enforce, and 
may institute and maintain any proceeding suitable to enforce, his rights of 
conversion as provided herein.

    Section 6.5  PROCEEDINGS BY TRUSTEE.  In case of an Event of Default
and subject to the provisions of Section 7.7 hereof, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either by 


                                      48
<PAGE>

suit in equity or by action at law or by proceeding in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained in 
this Indenture or in aid of the exercise of any power granted in this Indenture
or to enforce any other legal or equitable right vested in the Trustee by this
Indenture or by law.

    Section 6.6  REMEDIES CUMULATIVE AND CONTINUING.  Except as provided in 
Section 2.6, all powers and remedies given by this Article VI to the Trustee
or to the Noteholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of such powers and remedies or of any other powers
and remedies available to the Trustee or the holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture, and no delay or omission
of the Trustee or of any holder of any of the Notes to exercise any right or
power accruing upon any default or Event of Default occurring and continuing as
aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such default or any acquiescence therein; and, subject to the
provisions of Section 6.4, every power and remedy given by this Article VI or by
law to the Trustee or to the Noteholders may be exercised from time to time, and
as often as shall be deemed expedient, by the Trustee or by the Noteholders.

    Section 6.7  DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY 
OF NOTEHOLDERS.  The holders of a majority in aggregate principal amount of the
Notes at the time outstanding (determined in accordance with Section 8.4) shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power 
conferred on the Trustee; provided that (a) such direction shall not be in 
conflict with any rule of law or with this Indenture and (b) the Trustee may 
take any other action deemed proper by the Trustee that is not inconsistent 
with such direction.  The holders of a majority in aggregate principal amount 
of the Notes at the time outstanding (determined in accordance with Section 8.4)
may on behalf of the holders of all of the Notes waive any past default or 
Event of Default hereunder and its consequences except (i) a default in the 
payment of interest or premium, if any, on, or the principal of, the Notes, 
(ii) a failure by the Company to convert any Notes into Common Stock or cash, 
as the case may be, or (iii) a default in respect of a covenant or provisions 
hereof that under Article X cannot be modified or amended without the consent 
of the holders of all Notes then outstanding.  Whenever any default or Event of
Default hereunder shall have been waived as permitted by this Section 6.7, 
said default or Event of Default shall for all purposes of the Notes and this 
Indenture be deemed to have been cured and to be not continuing and the Company,
the Trustee and the holders of 


                                      49
<PAGE>

the Notes shall as reasonably possible be restored to their former positions and
rights hereunder; but no such waiver shall extend to any subsequent or other 
default or Event of Default or impair any right consequent thereon.

    Section 6.8  NOTICE OF DEFAULTS.  The Trustee shall, within 90 days after 
the occurrence of a default, mail to all Noteholders, as the names and addresses
of such holders appear upon the Note register, notice of all defaults of which 
a Responsible Officer has actual knowledge, unless such defaults shall have 
been cured or waived before the giving of such notice; provided that, except 
in the case of default in the payment of the principal of, premium, if any, or 
interest on any of the Notes, the Trustee shall be protected in withholding 
such notice if and so long as a Responsible Officer of the Trustee in good faith
determine that the withholding of such notice is in the interests of the 
Noteholders.

    Section 6.9  UNDERTAKING TO PAY COSTS.  All parties to this Indenture agree,
and each holder of any Note by his acceptance thereof shall be deemed to have 
agreed, that any court may, in its discretion, require, in any suit for the 
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; provided that the provisions of this Section 6.9
shall not apply to any suit instituted by the Trustee, to any suit instituted by
any Noteholder or group of Noteholders holding in the aggregate more than 10% in
principal amount of the Notes at the time outstanding determined in accordance
with Section 8.4 or to any suit instituted by any Noteholder for the enforcement
of the payment of the principal of, premium, if any, or interest on any Note on
or after the due date expressed in such Note or to any suit for the enforcement
of the right to convert any Note in accordance with the provisions of Article
XIV.

                                      50

<PAGE>

vested in it by this Indenture and use the same degree of care and skill in 
its exercise as a prudent person would exercise or use under the

         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture; provided that in the case of any such certificates
         or opinions that by any provision hereof are specifically required to
         be furnished to the Trustee, the Trustee shall be under a duty to
         examine the same to determine whether or not they conform to the
         requirements of this Indenture (but need not confirm or investigate
         the accuracy of mathematical calculations or other facts stated
         therein).  

         (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful

         (b) of this Section 7.1;

              (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer of the Trustee unless it

         facts reasonably available to the Trustee; and

              (iii)     the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.7.

Trustee is subject to paragraphs (a), (b), (c) and (e) of this Section 7.1.

         (e)  The Trustee may refuse to perform any duty or exercise any right
or power or extend or risk its own funds or

         Section 7.3  RELIANCE ON DOCUMENTS, OPINIONS, ETC.  Except as
otherwise provided in Section 7.1:

         (a)  The Trustee may rely and shall be protected in acting upon any
    resolution, certificate, statement, instrument, opinion, report, notice,
    request, consent, order, bond, debenture, coupon or other paper or document
    believed by it in good faith to be genuine and to have been signed or
    presented by the proper party or parties;

the compensation of a trustee of an express trust), and the Company shall pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with

discharge of this Indenture.

         Section 7.8  OFFICERS' CERTIFICATE AS EVIDENCE.  Except as otherwise
provided in Section 7.1, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence or bad faith on the part of the
Trustee, be deemed to be conclusively proved and established by an Officers'
Certificate delivered to the Trustee, and such Officers' Certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken or omitted by it under the
provisions of this Indenture upon the faith thereof.

         Section 7.9  CONFLICTING INTERESTS OF TRUSTEE.  In the event that the
Trust Indenture Act is applicable hereto, and if the Trustee has or shall
acquire a conflicting interest within the meaning of Trust Indenture Act Section

interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

Trust Indenture Act Section 310(a)(1) and Section 310(a)(5) and that has a
combined capital and surplus of at least $50,000,000.  If such person publishes
reports of condition at least annually, pursuant to law or to the requirements
of any supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such person shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time the Trustee shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article VII.

         Section 7.11  RESIGNATION OR REMOVAL OF TRUSTEE. 

         (a)  The Trustee may at any time resign by giving written notice of
such resignation to the Company; and the Company shall mail, or cause to be
mailed, notice thereof to the holders of Notes at their addresses as they shall
appear on the Note register.  Upon receiving such notice of resignation, the
Company shall promptly appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of 


                                      55

<PAGE>

Directors, one copy of which instrument shall be delivered to the resigning 
Trustee and one copy to the successor trustee. 

         (b)  In case at any time any of the following shall occur:

         (i)  the Trustee shall fail to comply with Section 7.9 after written
    request therefor by the Company or by any Noteholder who has been a BONA
    FIDE holder of a Note or Notes for at least six months; or

         (ii) the Trustee shall cease to be eligible in accordance with the
    provisions of Section 7.10 and shall fail to resign after written request
    therefor by the Company or by any such Noteholder; or

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

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee, or any Noteholder who
has been a BONA FIDE holder of a Note or Notes for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee.  Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, remove the Trustee and appoint a successor
trustee.

         (c)  The holders of a majority in aggregate principal amount of the
Notes at the time outstanding may at any time remove the Trustee and nominate a
successor trustee, which shall be deemed appointed as successor trustee unless
within ten days after notice to the Company of such nomination the Company
objects thereto, in which case the Trustee so removed or any Noteholder, upon
the terms and conditions and otherwise as provided in the next paragraph, may
petition any court of competent jurisdiction for an appointment of a successor
trustee.

         If no successor trustee shall have been so appointed and have accepted
appointment within 60 days after removal or the mailing of such notice of
resignation to the Noteholders, the Trustee resigning or being removed may
petition any court of competent jurisdiction for the appointment of a successor
trust-


                                      56

<PAGE>

ee, or, in the case of either resignation or removal, any Noteholder who has 
been a BONA FIDE holder of a Note or Notes for at least six months may, on 
behalf of himself and all others similarly situated, petition any such court 
for the appointment of a successor trustee.  Such court may thereupon, after 
such notice, if any, as it may deem proper and prescribe, appoint a successor 
trustee.

         (d)  Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 7.11 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 7.12.

         Section 7.12  ACCEPTANCE BY SUCCESSOR TRUSTEE.  Any successor trustee
appointed as provided in Section 7.11 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon, the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect as
if originally named as trustee herein; but on the written request of the Company
or of the successor trustee, the Trustee ceasing to act shall, upon payment of
any amounts then due it pursuant to the provisions of Section 7.7, execute and
deliver an instrument transferring to such successor trustee all the rights and
powers of the Trustee so ceasing to act.  Upon request of any such successor
trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor trustee all such
rights and powers.  Any Trustee ceasing to act shall, nevertheless, retain a
lien upon all property and funds held or collected by such trustee as such,
except for funds held in trust for the benefit of holders of particular Notes,
to secure any amounts then due it pursuant to the provisions of Section 7.7.

         No successor trustee shall accept appointment as provided in this
Section 7.12 unless at the time of such acceptance such successor trustee shall
be qualified under the provisions of Section 7.9 and eligible under the
provisions of Section 7.10.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 7.12, the Company shall mail or cause to be mailed notice of the
succession of such Trustee hereunder to the holders of Notes at their addresses
as they shall appear on the Note register.  If the Company fails to mail such
notice within ten days after acceptance of appointment by the successor 


                                      57

<PAGE>

trustee, the successor trustee shall cause such notice to be mailed at the 
expense of the Company.

         Section 7.13  SUCCESSOR, BY MERGER, ETC.  Any corporation into which
the Trustee may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee, shall be the
successor to the Trustee hereunder, provided such corporation shall be qualified
under the provisions of Section 7.9 and eligible under the provisions of Section
7.10 without the execution or filing of any paper or any further act on the part
of any of the parties hereto.

         Section 7.14  LIMITATION ON RIGHTS OF TRUSTEE AS CREDITOR.  If and
when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Notes) and the Trust Indenture Act is applicable hereto, the
Trustee shall be subject to the provisions of Trust Indenture Act Section 311(a)
or, if applicable, Trust Indenture Act Section 311(b) regarding the collection
of the claims against the Company (or any such other obligor).

                              CONCERNING THE NOTEHOLDERS

         Section 8.1  ACTION BY NOTEHOLDERS.  Whenever in this Indenture it is
provided that the holders of a specified percentage in aggregate principal
amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by Noteholders
in person or by agent or proxy appointed in writing, (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly
called and held in accordance with the provisions of Article IX or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of Noteholders.  Whenever the Company or the Trustee solicits the taking
of any action by the holders of the Notes, the Company or the Trustee may fix in
advance of such solicitation, a date as the record date for determining holders
entitled to take such action.  The record date shall be not more than 15 days
prior to the date of commencement of solicitation of such action.

         Section 8.2  PROOF OF EXECUTION BY NOTEHOLDERS.  Subject to the
provisions of Sections 7.1, 7.2 and 9.5, proof of the execution of any
instrument by a Noteholder or by agent or proxy shall be sufficient if made in

Note register or by a certificate of the Note registrar.

         The record of any Noteholders' meeting shall be proved in the manner
provided in Section 9.5.

         Section 8.3  WHO ARE DEEMED ABSOLUTE OWNERS.  The Company, the
Trustee, any paying agent, any conversion agent and any Note registrar may deem
the person in whose name such Note shall be registered upon the books of the
Company to be, and may treat such person as, the absolute owner of such Note
(whether or not such Note shall be overdue and notwithstanding any notation of
ownership or other writing thereon) for the purpose of receiving payment of or
on account of the principal of, premium, if any, and interest on such Note, for
conversion of such Note and for all other purposes; and neither the Company nor
the Trustee nor any paying agent nor any conversion agent nor any Note registrar
shall be affected by any notice to the contrary.  All such payments so made to
any holder for the time being, or upon order of such holder, shall be valid and,
to the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for monies payable upon any such Note.

         The Depositary shall be deemed to be the owner of any global Note for
all purposes, including receipt of notices to Noteholders and payment of
principal of, premium, if any, and interest on the Notes.  None of the Company,
the Trustee (in its capacity as Trustee), any paying agent or the Note registrar
(or co-registrar) shall have any responsibility for any aspect of the records
relating to or payments made on account of beneficial interests of a global Note
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

         Section 8.4  COMPANY-OWNED NOTES DISREGARDED.  In determining whether
the holders of the requisite aggregate principal amount of Notes have concurred
in any direction, consent, waiver or other action under this Indenture, Notes
that are owned by the Company or any other obligor on the Notes or by any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any other obligor on the Notes shall be
disregarded and deemed not to be outstanding for the purpose of any such
determination; provided that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, consent, waiver or other
action, only Notes that a Responsible Officer of the Trustee actually knows are
so owned shall be so disregarded.  


                                      59

<PAGE>

Notes so owned that have been pledged in good faith may be regarded as 
outstanding for the purposes of this Section 8.4 if the pledgee shall 
establish to the satisfaction of the Trustee the pledger's right to vote such 
Notes and that the pledgee is not the Company, any other obligor on the Notes 
or a person directly or indirectly controlling or controlled by or under 
direct or indirect common control with the Company or any such other obligor. 
 In the case of a dispute as to such right, any decision by the Trustee taken 
upon the advice of counsel shall be full protection to the Trustee.  Upon 
request of the Trustee, the Company shall furnish to the Trustee promptly an 
Officers' Certificate listing and identifying all Notes, if any, known by the 
Company to be owned or held by or for the account of any of the above 
described persons; and subject to Section 7.1, the Trustee shall be entitled 
to accept such Officers' Certificate as conclusive evidence of the facts 
therein set forth and of the fact that all Notes not listed therein are 
outstanding for the purpose of any such determination.

         Section 8.5  REVOCATION OF CONSENTS, FUTURE HOLDERS BOUND.  At any
time prior to (but not after) the evidencing to the Trustee, as provided in
Section 8.1, of the taking of any action by the holders of the percentage in
aggregate principal amount of the Notes specified in this Indenture in
connection with such action, any holder of a Note that is shown by the evidence
to be included in the Notes the holders of which have consented to such action
may, by filing written notice with the Trustee at its Corporate Trust Office and
upon proof of holding as provided in Section 8.2, revoke such action so far as
concerns such Note.  Except as aforesaid, any such action taken by the holder of
any Note shall be conclusive and binding upon such holder and upon all future
holders and owners of such Note and of any Notes issued in exchange or
substitution therefor, irrespective of whether any notation in regard thereto is
made upon such Note or any Note issued in exchange or substitution therefor.

    period may be shorter or longer than that allowed in the case of other
    defaults) or may provide for an immediate enforcement upon such default or
    may limit the remedies available to the Trustee upon such default;

         (e)  to provide for the issuance under this Indenture of Notes in
    coupon form (including Notes registrable as to principal only) and to
    provide for exchangeability of such Notes with the Notes issued hereunder
    in fully registered form and to make all appropriate changes for such
    purpose;


                                        63
<PAGE>

         (f)  to cure any ambiguity or to correct or supplement any provision
    contained herein or in any supplemental indenture that may be defective or
    inconsistent with any other provision contained herein or in any
    supplemental indenture, or to make such other provisions in regard to
    matters or questions arising under this Indenture that shall not adversely
    affect the interests of the holders of the Notes;

         (g)  to evidence and provide for the acceptance of appointment
    hereunder by a successor Trustee with respect to the Notes; or

         (h)  to modify, eliminate or add to the provisions of this Indenture
    to such extent necessary to effect the qualification of this Indenture
    under the Trust Indenture Act (if applicable), or under any similar federal
    statute hereafter enacted (if applicable).

         The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations that may be therein contained and to accept the
conveyance, transfer and assignment of any property thereunder, but the Trustee
shall not be obligated to, but may in its discretion, enter into any
supplemental indenture that affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

         Any supplemental indenture authorized by the provisions of this
Section 10.1 may be executed by the Company and the Trustee without the consent
of the holders of any of the Notes at the time outstanding, notwithstanding any
of the provisions of Section 10.2.

         Section 10.2  SUPPLEMENTAL INDENTURES WITH CONSENT OF NOTEHOLDERS. 
With the consent (evidenced as provided in Article VIII) of the holders of not
less than a majority in aggregate principal amount of the Notes at the time
outstanding, the Company, when authorized by a Board Resolution and the Trustee,
may from time to time and at any time enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or any
supplemental indenture or of modifying in any manner the rights of the holders
of the Notes; provided that no such supplemental indenture shall (i) without the
consent of the holders of each Note so affected, extend the fixed maturity of
any Note, or reduce the rate or extend the time of payment of interest thereon,
or reduce the principal amount thereof or premium, if any, thereon or reduce any
amount payable on redemption or repurchase thereof, alter the obligation of the
Company to repurchase the Notes at the option of the holder upon


                                        64
<PAGE>

the occurrence of a Change of Control or impair or affect the right of any 
Noteholder to institute suit for the payment thereof or make the principal 
thereof or interest or premium, if any, thereon payable in any coin or 
currency other than that provided in the Notes, modify the subordination 
provisions in a manner adverse to the holders of the Notes, or impair the 
right to convert the Notes into Common Stock or cash subject to the terms set 
forth herein or (ii) without the consent of the holders of all the Notes then 
outstanding, reduce the aforesaid percentage of Notes, the holders of which 
are required to consent to any such supplemental indenture.

         Upon the request of the Company, accompanied by a copy of a Board
Resolution certified by its Secretary or Assistant Secretary authorizing the
execution of any such supplemental indenture, and upon the filing with the
Trustee of evidence of the consent of Noteholders as aforesaid, the Trustee
shall join with the Company in the execution of such supplemental indenture
unless such supplemental indenture affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise, in which case the Trustee may in
its discretion, but shall not be obligated to, enter into such supplemental
indenture.

         It shall not be necessary for the consent of the Noteholders under
this Section 10.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

         Section 10.3  EFFECT OF SUPPLEMENTAL INDENTURES.  Any supplemental
indenture executed pursuant to the provisions of this Article X shall comply
with the Trust Indenture Act, as then in effect, if such supplemental indenture
is then required to so comply.  Upon the execution of any supplemental indenture
pursuant to the provisions of this Article X, this Indenture shall be and be
deemed to be modified and amended in accordance therewith and the respective
rights, limitation of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Notes shall thereafter
be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and
conditions of this Indenture for any and all purposes.

         Section 10.4  NOTATION ON NOTES.  Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of
this Article X may bear a notation in form approved by the Company as to any
matter provided for in such supplemental indenture, but they need not do so. 
After notice to the Trustee, if the Company shall determine to add such a
notation, new Notes so modified as to conform, in the opinion


                                        65
<PAGE>

of the Board of Directors, to any modification of this Indenture contained in 
any such supplemental indenture may, at the Company's expense, be prepared 
and executed by the Company, authenticated by the Trustee (or an 
authenticating agent duly appointed by the Trustee pursuant to Section 16.14) 
and delivered in exchange for the Notes then outstanding, upon surrender of 
such Notes then outstanding.

         Section 10.5  EVIDENCE OF COMPLIANCE OF SUPPLEMENTAL INDENTURE TO BE
FURNISHED TO THE TRUSTEE.  The Trustee shall be furnished with and, subject to
the provisions of Sections 7.1 and 7.2, may rely conclusively upon an Officers'
Certificate and an Opinion of Counsel as conclusive evidence that any
supplemental indenture executed pursuant hereto complies with the requirements
of this Article X.

                                      ARTICLE XI

                       CONSOLIDATION, MERGER, SALE, CONVEYANCE,
                                  TRANSFER AND LEASE


         Section 11.1  COMPANY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.  The
Company shall not consolidate with or merge with or into, or convey, transfer or
lease all or substantially all of its assets (determined on a consolidated
basis) to any person unless: (i) either the Company is the resulting, surviving
or transferee person (the "Successor Company") or the Successor Company is a
person organized and existing under the laws of the United States or any State
thereof or the District of Columbia, and the Successor Company (if not the
Company) expressly assumes by a supplemental indenture, executed and delivered
to the Trustee, in form satisfactory to the Trustee, all the obligations of the
Company under this Indenture and the Notes, including the rights pursuant to
Article XIV hereof, (ii) immediately after giving effect to such transaction, no
Event of Default has happened and is continuing and (iii) the Company delivers
to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating
that such consolidation, merger or transfer and such supplemental indenture (if
any) comply with this Indenture.

         Section 11.2  SUCCESSOR COMPANY TO BE SUBSTITUTED.  In case of any
such consolidation, merger, sale, conveyance, transfer or lease and upon the
assumption by the Successor Company, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the due and
punctual payment of the principal of, premium, if any, and interest on all of
the Notes and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Company, such Successor
Company shall succeed to and be substituted for the Company, with the same
effect as if it


                                        66
<PAGE>

had been named herein as the party hereto.  When a Successor Company duly 
assumes all the obligations of the Company pursuant to this Indenture and the 
Notes, the predecessor shall be released from all such obligations.

         Section 11.3  OPINION OF COUNSEL TO BE GIVEN TO TRUSTEE.  The Trustee,
subject to Sections 7.1 and 7.2, shall receive an Officers' Certificate and an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or lease and any such assumption complies with the
provisions of this Article XI.


                                     ARTICLE XII

                       SATISFACTION AND DISCHARGE OF INDENTURE;
                                   UNCLAIMED MONEYS


         Section 12.1  LEGAL DEFEASANCE AND COVENANT DEFEASANCE OF THE NOTES.

         (a)  The Company may, at its option by Board Resolution, at any time,
with respect to the Notes, elect to have either paragraph (b) or paragraph (c)
below be applied to the outstanding Notes upon compliance with the conditions
set forth in paragraph (d).

         (b)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company shall be deemed to have been
released and discharged from its obligations with respect to the outstanding
Notes on the date the conditions set forth in paragraph (d) below are satisfied
(hereinafter, "legal defeasance").  For this purpose, such legal defeasance
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by the outstanding Notes, which shall thereafter be
deemed to be "outstanding" only for the purposes of the Sections of and matters
under this Indenture referred to in clauses (i) and (ii) below and to have
satisfied all its other obligations under such Notes and this Indenture insofar
as such Notes are concerned, except for the following, which shall survive until
otherwise terminated or discharged hereunder: (i) the rights of holders of
outstanding Notes to receive solely from the trust fund described in paragraph
(d) below and as more fully set forth in such paragraph, payments in respect of
the principal of, premium, if any, and interest on such Notes when such payments
are due and (ii) obligations listed in Section 12.3.

         (c)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (c), the Company shall be


                                        67
<PAGE>

released and discharged from its obligations under any covenant contained in 
Article XI and Section 3.5 with respect to the outstanding Notes on and after 
the date the conditions set forth in paragraph (d) are satisfied 
(hereinafter, "covenant defeasance"), and the Notes shall thereafter be 
deemed to be not "outstanding" for the purpose of any direction, waiver, 
consent or declaration or act of holders (and the consequences of any 
thereof) in connection with such covenants, but shall continue to be deemed 
"outstanding" for all other purposes hereunder.  For this purpose, such 
covenant defeasance means that, with respect to the outstanding Notes, the 
Company may omit to comply with and shall have no liability in respect of any 
term, condition or limitation set forth in any such covenant, whether 
directly or indirectly, by reason of any reference elsewhere herein to any 
such covenant or by reason of any reference in any such covenant to any other 
provision herein or in any other document, and such omission to comply shall 
not constitute a Default or an Event of Default under Section 6.1, but, 
except as specified above, the remainder of this Indenture and such Notes 
shall be unaffected thereby.

         (d)  The following shall be the conditions to application of either
paragraph (b) or paragraph (c) above to the outstanding Notes:

              (i) The Company shall have irrevocably deposited in trust with
    the Trustee, pursuant to an irrevocable trust and security agreement in
    form and substance satisfactory to the Trustee, cash or non-callable U.S.
    Government Obligations maturing as to principal and interest at such times,
    or a combination thereof, in such amounts as are sufficient, without
    consideration of the reinvestment of such interest and after payment of all
    federal, state and local taxes or other charges or assessments in respect
    thereof payable by the Trustee, in the opinion of a nationally recognized
    firm of independent public accountants expressed in a written certification
    thereof (in form and substance reasonably satisfactory to the Trustee)
    delivered to the Trustee, to pay the principal of, premium, if any, and
    interest on the outstanding Notes on the dates on which any such payments
    are due and payable in accordance with the terms of this Indenture and of
    the Notes as well as all other sums payable hereunder by the Company;

              (ii)  (A)  No Event of Default shall have occurred or be
    continuing on the date of such deposit, and (B) no Default or Event of
    Default under Section 6.1(f) or 6.1(g) shall occur on or before the 123rd
    day after the date of such deposit;


                                        68
<PAGE>

              (iii) Such deposit shall not result in a Default under this
    Indenture or a breach or violation of, or constitute a default under, any
    other instrument or agreement to which the Company is a party or by which
    it or its property is bound;

              (iv) In the case of a legal defeasance under paragraph (b) above,
    the Company has delivered to the Trustee an Opinion of Counsel in form and
    substance reasonably satisfactory to the Trustee stating that (A) the
    Company has received from, or there has been published by, the Internal
    Revenue Service a ruling applicable to such a defeasance or (B) since the
    date of this Indenture, there has been a change in the applicable federal
    income tax law, in either case to the effect that, and based thereon such
    opinion shall confirm that, the holders of the Notes shall not recognize
    income, gain or loss for federal income tax purposes as a result of such
    deposit, defeasance and discharge and shall be subject to federal income
    tax on the same amounts and in the same manner and at the same times as
    would have been the case if such deposit, defeasance and discharge had not
    occurred; and, in the case of a covenant defeasance under paragraph (c)
    above, the Company shall deliver to the Trustee an Officers' Certificate
    and an Opinion of Counsel, in form and substance reasonably satisfactory to
    the Trustee, to the effect that holders of the Notes shall not recognize
    income, gain or loss for federal income tax purposes as a result of such
    deposit and defeasance and shall be subject to federal income tax on the
    same amounts and in the same manner and at the same times as would have
    been the case if such deposit and defeasance had not occurred;

              (v) The holders shall have a perfected security interest under
    applicable law in the cash or U.S. Government Obligations deposited
    pursuant to Section 12.1(d)(i) above;

              (vi) The Company shall have delivered to the Trustee an Opinion
    of Counsel, in form and substance reasonably satisfactory to the Trustee,
    to the effect that, after the passage of 123 days following the deposit,
    the trust funds shall not be subject to any applicable bankruptcy,
    insolvency, reorganization or similar law affecting creditors' rights
    generally;

              (vii) Such defeasance shall not cause the Trustee to have a
    conflicting interest with respect to any securities of the Company; and

              (viii) The Company has delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel in form 


                                        69
<PAGE>

    and substance reasonably satisfactory to the Trustee, each stating that all
    conditions precedent specified herein relating to the defeasance 
    contemplated by this Section 12.1 have been complied with;

provided, that no deposit under clause (i) shall be effective to terminate 
the obligations of the Company under the Notes or this Indenture prior to the 
passage of 123 days following such deposit.

         Section 12.2  TERMINATION OF OBLIGATIONS UPON CANCELLATION OF THE
NOTES.  In addition to the Company's rights under Section 12.1, the Company may
terminate all of its obligations under this Indenture (subject to Section 12.3)
when:

         (a)  (i) all Notes theretofore authenticated and delivered (other than
    Notes that have been destroyed, lost or stolen and that have been replaced,
    converted or paid as provided in Section 2.6) have been delivered to the
    Trustee for cancellation; and

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

         (b)  (i) the Notes not previously delivered to the Trustee for
    cancellation shall have become due and payable or are by their terms to
    become due and payable within one year or are to be called for redemption
    under arrangements satisfactory to the Trustee upon delivery of notice,
    (ii) the Company shall have irrevocably deposited with the Trustee, as
    trust funds, cash, in an amount sufficient to pay principal of premium, if
    any, and interest on the outstanding Notes, to maturity or redemption, as
    the case may be, (iii) such deposit shall not result in a breach or
    violation of, or constitute a default under, any agreement or instrument
    pursuant to which the Company is a party or by which it or its property is
    bound and (iv) the Company has delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel in form and substance reasonably
    satisfactory to the Trustee, each stating that all conditions related to
    such defeasance have been complied with.

         Section 12.3  SURVIVAL OF CERTAIN OBLIGATIONS.  Notwithstanding the
satisfaction and discharge of this Indenture and of the Notes referred to in
Section 12.1 or 12.2, the respective obligations of the Company and the Trustee
under Sections 2.3, 2.4, 2.5, 2.6, 3.1, 4.2, 5.1, 6.4, 6.9, 7.6, 7.11, 12.5,
12.6, 12.7, Articles XIV and XV shall survive until the Notes are no longer
outstanding, and thereafter, the obligations of the


                                        70

<PAGE>

Company and the Trustee under Sections 6.9, 7.6, 12.5, 12.6 and 12.7 shall 
survive.  Nothing contained in this Article XII shall abrogate any of the 
rights, obligations or duties of the Trustee under this Indenture.

         Section 12.4  ACKNOWLEDGMENT OF DISCHARGE BY TRUSTEE.  Subject to 
Section 12.7, after (i) the conditions of Section 12.1 or 12.2 have been 
satisfied, (ii) the Company has paid or caused to be paid all other sums 
payable hereunder by the Company and (iii) the Company has delivered to the 
Trustee an Officers' Certificate and an Opinion of Counsel, each stating that 
all conditions precedent referred to in clause (i) above relating to the 
satisfaction and discharge of this Indenture have been complied with, the 
Trustee upon written request shall acknowledge in writing the discharge of 
the Company's obligations under this Indenture except for those surviving 
obligations specified in Section 12.3.

         Section 12.5  APPLICATION OF TRUST ASSETS.  The Trustee shall hold 
any cash or U.S. Government Obligations deposited with it in the irrevocable 
trust established pursuant to Section 12.1 or 12.2, as the case may be.  The 
Trustee shall apply the deposited cash or the U.S. Government Obligations, 
together with earnings thereon in accordance with this Indenture and the 
terms of the irrevocable trust agreement established pursuant to Section 12.1 
or 12.2, as the case may be, to the payment of principal of, premium, if any, 
and interest on the Notes.  The cash or U.S. Government Obligations so held 
in trust and deposited with the Trustee in compliance with Section 12.1 or 
12.2, as the case may be, shall not be part of the trust estate under this 
Indenture, but shall constitute a separate trust fund for the benefit of all 
holders entitled thereto.  Except as specifically provided herein, the 
Trustee shall not be requested to invest any amounts held by it for the 
benefit of the holders or pay interest on uninvested amounts to any holder.

         The Company shall pay and indemnify the Trustee against any tax, fee 
or other charge imposed on or assessed against the U.S. Government 
Obligations deposited pursuant to Section 12.1 hereof or Section 12.2 hereof 
or the principal and interest received in respect thereof other than any such 
tax, fee or other charge which by law is for the account of the holders of 
outstanding Notes.

         Section 12.6  REPAYMENT TO THE COMPANY; UNCLAIMED MONEY.  Subject to
applicable laws governing escheat of such property, and upon termination of the
trust established pursuant to Section 12.1 hereof or 12.2 hereof, as the case
may be, the Trustee shall promptly pay to the Company upon written request any
excess cash or U.S. Government Obligations held by them.  Additionally, if
amounts for the payment of principal, premium, 


                                      71

<PAGE>

if any, or interest remains unclaimed for two years, the Trustee shall, upon 
written request, pay such amounts back to the Company forthwith.  Thereafter, 
all liability of the Trustee with respect to such amounts shall cease.  After 
payment to the Company, holders entitled to such payment must look to the 
Company for such payment as general creditors unless an applicable abandoned 
property law designates another person.

         Section 12.7  REINSTATEMENT.  If the Trustee is unable to apply any
cash or U.S. Government Obligations in accordance with Section 12.1 or 12.2 by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 12.1 or 12.2 until such time as the Trustee is permitted to apply all
such cash or U.S. Government Obligations in accordance with Section 12.1 or
12.2, as the case may be; provided that if the Company makes any payment of
principal of, premium, if any, or interest on any Notes following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the holders of such Notes to receive such payment from the amounts held by
the Trustee.


                                     ARTICLE XIII

                       IMMUNITY OF INCORPORATORS, SHAREHOLDERS,
                                OFFICERS AND DIRECTORS


         Section 13.1  INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS.  No
recourse for the payment of the principal of, or premium, if any, or interest on
any Note, or for any claim based thereon or otherwise in respect thereof, and no
recourse under or upon any obligation, covenant or agreement of the Company in
this Indenture or in any supplemental indenture or in any Note, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, shareholder, officer or director, as such, past, present or
future, of the Company or of any successor entity, either directly or through
the Company or any successor entity, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise; it being expressly understood that all such liability is hereby
expressly waived and released as a condition of, and as a consideration for, the
execution of this Indenture and the issuance of the Notes.

                                     ARTICLE XIV

                                 CONVERSION OF NOTES

         Section 14.1  RIGHT TO CONVERT.

              (a)  Subject to and upon compliance with the provisions of this 
Indenture, the holder of any Note shall have the right, at the option of such 
holder, at any time after 90 days following the latest date of original 
issuance of the Notes and prior to the close of business on November 28, 2003 
(except that, with respect to any Note or portion of a Note that shall be 
called for redemption or delivered for repurchase, such right shall terminate 
at the close of business one Business Day immediately preceding the date 
fixed for redemption or repurchase of such Note or portion of a Note unless 
the Company shall default in payment due upon redemption thereof) to convert 
the principal amount of any such Note, or any portion of such principal 
amount that is $1,000 or an integral multiple thereof, into that number of 
fully paid and nonassessable shares of Common Stock (as such shares shall 
then be constituted) obtained by dividing the aggregate principal amount of 
the Notes or portion thereof surrendered for conversion by the Conversion 
Price in effect at such time rounded to the nearest 1/100,000th of a share 
(with 0.000005 being rolled upward) as such amount shall be certified by the 
Company as provided in an Officers' Certificate, by surrender of the Note so 
to be converted in whole or in part in the manner provided in Section 14.2.  
A Note (or portion thereof) in respect of which a holder is exercising its 
option to require repurchase upon a change of control pursuant to Section 3.5 
of this Indenture, may only be converted if such holder withdraws its 
election to exercise said redemption option in accordance with the terms of 
this Indenture.  A holder of Notes is not entitled to any rights of a holder 
of Common Stock until such holder has converted such holder's Notes to Common 
Stock and only to the extent such Notes are deemed to have been converted to 
Common Stock under this Article XIV.

              (b)  In the event a holder desires to convert all, or any
portion, of its Notes into shares of Common Stock (or other securities into
which the Notes are then convertible) and the Company does not have authorized a
sufficient number of shares of Common Stock (or other securities into which the
Notes are then convertible) for such conversion, then in lieu of delivering
shares of Common Stock (or other securities into which the Notes are then
convertible) upon conversion pursuant to 14.1(a) of that portion of such
holder's Notes for which there is an insufficient number of shares of Common
Stock (or other securities into which the Notes are then convertible) (the "Cash
Equivalent Notes"), the Company shall pay to the holder 


                                      73

<PAGE>

converting the Cash Equivalent Notes who properly exercises the conversion 
privilege, as set forth in Section 14.2, an amount, as calculated by the 
Company and certified to the Trustee in an Officers' Certificate of the 
Company, in cash equal to the Market Cash Conversion Price of the shares of 
Common Stock into which such Cash Equivalent Notes are then convertible.

              (c)  In the event that the Company directs the Trustee to pay 
cash upon any conversion in lieu of delivering shares of Common Stock or any 
other securities, as the case may be, the Company shall deliver to the 
Trustee written notice of such election not later than the close of business 
on the first Trading Day after the date of receipt by the Trustee of the 
notice of conversion delivered by such holder pursuant to Section 14.2, and 
the Trustee shall notify by facsimile the contact person specified in the 
holder's Conversion Notice of such election by the Company to such holder.  
In such event, notwithstanding any other provisions in this Article XIV, in 
lieu of delivering Common Stock upon conversion of such Notes surrendered in 
accordance with Section 14.2, the Company shall pay or direct the Trustee to 
pay the holder surrendering such securities an amount in cash equal to the 
Market Cash Conversion Price of the shares of Common Stock, plus any cash and 
other property theretofore apportioned to such shares of Common Stock in 
accordance with Section 14.2.  Prior to or concurrently with such cash 
payment, the Company will provide the Trustee with an Officers' Certificate 
setting forth the Market Cash Conversion Price and will deposit with the 
paying agent the cash so payable. The Trustee shall have no obligation or 
liability with respect to the calculation of the Market Cash Conversion Price.

         Section 14.2  EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON 
STOCK ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS.  In order to 
exercise the conversion privilege with respect to any Note in definitive 
form, the holder of any such Note to be converted in whole or in part shall 
surrender such Note, duly endorsed, at an office or agency maintained by the 
Company pursuant to Section 4.2, accompanied by the funds, if any, required 
by the penultimate paragraph of this Section 14.2, and shall give written 
notice of conversion in the form provided on the form of Note (or such other 
notice that is acceptable to the Company) to the office or agency that the 
holder elects to convert such Note or the portion thereof specified in said 
notice.  Such notice shall state the name, telephone number and facsimile 
number of the contact person for the Conversion Notice and shall also state 
the name or names (with address) in which the certificate or certificates for 
shares of Common Stock that shall be issuable on such conversion shall be 
issued and shall be accompanied by transfer taxes, if required pursuant to 
Section 14.7.  Each such Note surrendered for conversion shall, unless the 
shares issuable on conversion 


                                      74

<PAGE>

are to be issued in the name of the holder of such Note as it appears on the 
Note register, be duly endorsed by, or be accompanied by instruments of 
transfer in form satisfactory to the Company duly executed by, the holder or 
his duly authorized attorney.

         In order to exercise the conversion privilege with respect to any
interest in a global Note, the beneficial holder must complete the appropriate
instruction form for conversion pursuant to the Depositary's book-entry
conversion program and follow the other procedures set forth in such program.

         As promptly as practicable after satisfaction of the requirements for
conversion set forth above, subject to Section 14.1(b) and in compliance with
any restrictions on transfer if shares issuable on conversion are to be issued
in a name other than that of the Noteholder (as if such transfer were a transfer
of the Note or Notes (or portion thereof) so converted), the Company shall issue
and shall deliver to such holder at the office or agency maintained by the
Company for such purpose pursuant to Section 4.2, a certificate or certificates
for the number of full shares issuable upon the conversion of such Note or
portion thereof in accordance with the provisions of this Article XIV and a
check or cash in respect of any fractional interest in respect of a share of
Common Stock arising upon such conversion, as provided in Section 14.3. In case
any Note of a denomination greater than $1,000 shall be surrendered for partial
conversion, and subject to Section 2.3, the Company shall execute and the
Trustee shall authenticate and make available for delivery to the holder of the
Note so surrendered, without charge to him, a new Note or Notes in authorized
denominations in an aggregate principal amount equal to the unconverted portion
of the surrendered Note.

         Each conversion shall be deemed to have been effected as to any such
Note (or portion thereof) on the date on which the requirements set forth above
in this Section 14.2 have been satisfied as to such Note (or portion thereof),
and, subject to Section 14.1(b), the person in whose name any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become on said date the holder of record of the shares
represented thereby; provided that any such surrender on any date when the stock
transfer books of the Company shall be closed shall constitute the person in
whose name the certificates are to be issued as the record holder thereof for
all purposes on the next succeeding day on which such stock transfer books are
open, but such conversion shall be at the Conversion Price in effect on the date
upon which such Note shall have been surrendered.


                                      75

<PAGE>

         Any Note or portion thereof surrendered for conversion during the
period from the close of business on the record date for any interest payment
date to the opening of business on the next succeeding interest payment date
shall (unless such Note or portion thereof being converted shall have been
called for redemption on a redemption date during the period from the close of
business on or after any record date for the payment of interest to the close of
business on the business day following the corresponding interest payment date)
be accompanied by payment, in funds acceptable to the Company, of an amount
equal to the interest payable on such succeeding interest payment date on the
principal amount being converted; provided that no such payment need be made if
there shall exist at the time of conversion a default in the payment of interest
on the Notes.  An amount equal to such payment shall be paid by the Company on
the corresponding interest payment date to the holder of such Note at the close
of business on such record date; provided that if the Company shall default in
the payment of interest on such interest payment date, such amount shall be paid
to the person who made such required payment.  The interest payment with respect
to a Note called for redemption on a date between the close of business on any
record date for the payment of interest to the close of business on the business
day following the corresponding interest payment date and surrendered for
conversion during that period shall be payable on the corresponding interest
payment date to the registered holder at the close of business on that record
date (notwithstanding the conversion of such Note before the corresponding
interest payment date) and a holder who elects to convert during that period
need not include funds equal to the interest paid.  Except as provided above in
this Section 14.2, no adjustment shall be made for interest accrued on any Note
converted or for dividends on any shares issued upon the conversion of such Note
as provided in this Article XIV.

         Upon the conversion of an interest in a global Note, the Trustee, or
the Custodian at the direction of the Trustee, shall make a notation on such
global Note as to the reduction in the principal amount represented thereby.

         Section 14.3  CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES.  No
fractional shares of Common Stock or scrip representing fractional shares shall
be issued upon conversion of Notes.  Subject to Section 14.1(b), (i) if more
than one Note shall be surrendered for conversion at one time by the same
holder, the number of fully paid and nonassessable shares of Common Stock
issuable upon conversion of a Note shall be determined by dividing the aggregate
principal amount of such Notes or portion thereof surrendered for conversion by
the Conversion Price in effect at such time and (ii) the aggregate number of
shares of Common Stock issuable upon conversion shall be rounded to the nearest
1/100,000th of a share (with .0000005 


                                      76

<PAGE>

being rolled upward).  If any fractional share of stock would be issuable 
upon the conversion of any Note or Notes, the Company shall make an 
adjustment therefor in cash at the current market value thereof.  The current 
market value of a share of Common Stock shall be determined by multiplying 
the fractional share by the Closing Price on the Trading Day immediately 
preceding the date on which the Notes (or specified portions thereof) are 
deemed to have been converted.

         Section 14.4  CONVERSION PRICE.  The Conversion Price shall be as
specified in the forms of Notes (herein called the "Conversion Price") attached
as Exhibits A, B and C hereto, subject to adjustment as provided in this Article
XIV.

         Section 14.5  ADJUSTMENT OF CONVERSION PRICE.  The Conversion Price
shall be adjusted from time to time by the Company as follows:

         (a)  In case the Company shall (i) pay a dividend or make a
    distribution on its outstanding Common Stock in shares of its Common Stock,
    (ii) subdivide or split its outstanding Common Stock into a greater number
    of shares, (iii) combine its outstanding Common Stock into a smaller number
    of shares or (iv) issue any shares of capital stock by reclassification of
    its Common Stock, the conversion price in effect immediately prior thereto
    shall be adjusted so that the holder of any Notes thereafter surrendered
    for conversion shall be entitled to receive the number of shares of Common
    Stock of the Company which such holder would have owned or have been
    entitled to receive after the occurrence of any of the events described
    above had such Notes been surrendered for conversion immediately prior to
    the occurrence of such event or the record date therefor, whichever is
    earlier.  An adjustment made pursuant to this subsection (a) shall become
    effective immediately after the close of business on the record date for
    determination of shareholders entitled to receive such dividend or
    distribution in the case of a dividend or distribution (except as provided
    in Section 14.5(j)) and shall become effective immediately after the close
    of business on the effective date in the case of a subdivision, split,
    combination or reclassification.  Any shares of Common Stock issuable in
    payment of a dividend shall be deemed to have been issued immediately prior
    to the close of business on the record date for such dividend for purposes
    of calculating the number of outstanding shares of Common Stock under
    Sections 14.5(b) and (c).

         (b)  In case the Company shall issue rights, options or warrants to
    all holders of its outstanding shares of Common Stock entitling them to
    subscribe for or purchase shares of 


                                      77

<PAGE>

    Common Stock at a price per share less than the Current Market Price 
    (as defined in Section 14.5(g)) on the Record Date fixed for determination
    of shareholders entitled to receive such rights, options or warrants, the 
    Conversion Price shall be adjusted so that the same shall equal the price 
    determined by multiplying the Conversion Price in effect at the opening of 
    business on the date after the Record Date by a fraction the numerator of 
    which shall be the number of shares of Common Stock outstanding at the close
    of business on the Record Date plus the number of shares that the aggregate
    offering price of the total number of shares so offered would purchase at 
    such Current Market Price, and the denominator of which shall be the number
    of shares of Common Stock outstanding on the close of business on the Record
    Date plus the total number of additional shares of Common Stock so offered 
    for subscription or purchase.  Such adjustment shall become effective 
    immediately after the opening of business on the day following the Record 
    Date fixed for determination of shareholders entitled to receive such 
    rights, options or warrants.  To the extent that shares of Common Stock are
    not delivered  after the expiration or termination of such rights, options 
    or warrants, the Conversion Price shall be readjusted to the Conversion 
    Price that would then be in effect had the adjustments made upon the 
    issuance of such rights, options or warrants been made on the basis of 
    delivery of only the number of shares of Common Stock actually delivered. 
    In the event that such rights, options or warrants are not so issued, the 
    Conversion Price shall again be adjusted to be the Conversion Price that 
    would then be in effect if such date fixed for the determination of 
    shareholders entitled to receive such rights, options or warrants had not 
    been fixed. In determining whether any rights, options or warrants entitle 
    the holders to subscribe for or purchase shares of Common Stock at less than
    such Current Market Price, and in determining the aggregate offering price 
    of such shares of Common Stock, there shall be taken into account any 
    consideration received for such rights, options or warrants, the value of 
    such consideration, if other than cash, to be determined by the Board of
    Directors.

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


                                      78

<PAGE>

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

         (d)  In case the Company shall, by dividend or otherwise, distribute
    to all holders of its Common Stock shares of any class of capital stock of
    the Company (other than any dividends or distributions to which Section
    14.5(a) applies) or evidences of its indebtedness or assets (including
    securities, but excluding any rights, options or warrants referred to in
    Section 14.5(b), and excluding any dividend or distribution (x) in
    connection with the liquidation, dissolution or winding-up of the Company,
    whether voluntary or involuntary, (y) exclusively in cash or (z) referred
    to in Section 14.5(a) (any of the foregoing hereinafter in this Section
    14.5(d) called the "Securities")), then, in each such case, the Conversion
    Price shall be reduced so that the same shall be equal to the price
    determined by multiplying the Conversion Price in effect immediately prior
    to the close of business on the Record Date (as defined in Section 14.5(g))
    with respect to such distribution by a fraction of which the numerator
    shall be the Current Market Price (determined as provided in Section
    14.5(g)) on such date less the fair market value (as determined by the
    Board of Directors, whose determination shall be conclusive and described
    in a Board Resolution) on such date of the portion of the Securities so
    distributed applicable to one share of Common Stock and the denominator
    shall be such Current Market Price, such reduction to become effective
    immediately prior to the opening of business on the day following the
    Record Date; provided that in the event the then fair market value (as so
    determined) of the portion of the Securities so distributed applicable to
    one share of Common Stock is equal to or greater than the Current Market
    Price on the Record Date, in lieu of the foregoing adjustment, adequate
    provision shall be made so that each Noteholder shall have the right to
    receive upon conversion the amount of Securities such holder would have
    received had such holder converted each Note on such date.  In the event
    that such dividend or distribution is not so paid or made, the Conversion
    Price shall again be adjusted to be the Conversion Price that would then be
    in effect if such dividend or distribution had not been declared.  If the
    Board of Directors determines the fair market value of any distribution for
    purposes of this Section 14.5(d) by reference to the actual or when issued
    trading market for any securities comprising all or part of such
    distribution, it must in doing so consider the prices in such market over


                                      79

<PAGE>

    the same period used in computing the Current Market Price pursuant to
    Section 14.5(g) to the extent possible.

         Notwithstanding the foregoing provisions of this Section 14.5(d), no
    adjustment shall be made hereunder for any distribution of Securities if
    the Company makes proper provision so that each Noteholder who converts a
    Note (or any portion thereof) after the date fixed for determination of
    shareholders entitled to receive such distribution shall be entitled to
    receive upon such conversion, in addition to the shares of Common Stock
    issuable upon such conversion, the amount and kind of Securities that such
    holder would have been entitled to receive if such holder had, immediately
    prior to such determination date, converted such Note into Common Stock;
    provided that, with respect to any Securities that are convertible,
    exchangeable or exercisable, the foregoing provision shall only apply to
    the extent (and so long as) the Securities receivable upon conversion of
    such Note would be convertible, exchangeable or exercisable, as applicable,
    without any loss of rights or privileges for a period of at least 60 days
    following conversion of such Note.

         Rights, options or warrants distributed by the Company to all holders
    of Common Stock entitling the holders thereof to purchase shares of the
    Company's capital stock (either initially or under certain circumstances),
    which rights, options or warrants, until the occurrence of a specified
    event or events (the "Trigger Event") (i) are deemed to be transferred with
    such shares of Common Stock, (ii) are not exercisable and (iii) are also
    issued in respect of future issuances of Common Stock, shall not be deemed
    distributed for purposes of this Section 14.5(d) (and no adjustment to the
    Conversion Price under Section 14.5(d) shall be required) until the
    occurrence of the earliest Trigger Event.  In addition, in the event of any
    distribution of rights, options or warrants, or any Trigger Event with
    respect thereto, that shall have resulted in an adjustment to the
    Conversion Price under this Section 14.5(d), (1) in the case of any such
    rights, options or warrants that shall all have been redeemed or
    repurchased without exercise by any holders thereof, the Conversion Price
    shall be readjusted upon such final redemption or repurchase to give effect
    to such distribution or Trigger Event, as the case may be, as though it
    were a cash distribution, equal to the per share redemption or repurchase
    price received by a holder of Common Stock with respect to such rights,
    options or warrants (assuming such holder had retained such rights, options
    or warrants), made to all holders of Common Stock as of the date of such
    redemption or repurchase, and (2) in the case of such rights, options or
    warrants all of which shall


                                      80

<PAGE>

    have expired or been terminated without exercise by any holder 
    thereof, the Conversion Price shall be readjusted as if such issuance
    had not occurred.

         For purposes of this Section 14.5(d) and Sections 14.5(a) and (b), any
    dividend or distribution to which this Section 14.5(d) is applicable that
    also includes shares of Common Stock, or rights, options or warrants to
    subscribe for or purchase shares of Common Stock (or both), shall be deemed
    instead to be (1) a dividend or distribution of the evidences of
    indebtedness, assets or shares of capital stock other than such shares of
    Common Stock or rights, options or warrants (and any Conversion Price
    reduction required by this Section 14.5(d) with respect to such dividend or
    distribution shall then be made) immediately followed by (2) a dividend or
    distribution of such shares of Common Stock or such rights, options or
    warrants (and any further Conversion Price reduction required by Sections
    14.5(a) and (b) with respect to such dividend or distribution shall then be
    made) except (A) the Record Date of such dividend or distribution shall be
    substituted as "the date fixed for the determination of shareholders
    entitled to receive such dividend or other distribution" and "the date
    fixed for such determination" within the meaning of Sections 14.5(a) and
    (b) and (B) any shares of Common Stock included in such dividend or
    distribution shall not be deemed "outstanding at the close of business on
    the date fixed for such determination" within the meaning of Section
    14.5(a).

         (e)  In case the Company shall, by dividend or otherwise, distribute
    to all holders of its Common Stock cash (excluding any cash that is
    distributed upon a merger or consolidation to which Section 14.6 applies or
    as part of a distribution referred to in Section 14.5(d) for which an
    adjustment to the Conversion Price is provided therein) in an aggregate
    amount that, combined together with (1) the aggregate amount of any other
    such distributions to all holders of its Common Stock made exclusively in
    cash within the 12 months preceding the date of payment of such
    distribution, and in respect of which no adjustment pursuant to this
    Section 14.5(e) has been made, and (2) the aggregate of any cash plus the
    fair market value (as determined by the Board of Directors, whose
    determination shall be conclusive and described in a Board Resolution) of
    consideration payable in respect of any tender offer, by the Company or any
    of its Subsidiaries for all or any portion of the Common Stock concluded
    within the 12 months preceding the date of payment of such distribution,
    and in respect of which no adjustment pursuant to Section 14.5(f) has been
    made, exceeds 20.0% of the product of the Current Market Price (determined
    as provided in Section 14.5(g)) on the Record


                                     81

<PAGE>

    Date with respect to such distribution times the number of shares of Common
    Stock outstanding on such date, then, and in each such case, immediately
    after the close of business on such date, unless the Company elects to 
    reserve such cash for distribution to the holders of the Notes upon the 
    conversion of the Notes so that any such holder converting Notes shall 
    receive upon such conversion, in addition to the shares of Common Stock 
    to that such holder is entitled, the amount of cash which such holder 
    would have received if such holder had, immediately prior to the Record
    Date for such distribution of cash, converted its Notes into Common 
    Stock, the Conversion Price shall be reduced so that the same shall 
    equal the price determined by multiplying the Conversion Price in 
    effect immediately prior to the close of business on such date by a 
    fraction (i) the numerator of which shall be equal to the Current 
    Market Price on the Record Date less an amount equal to the quotient 
    of (x) the excess of such combined amount over such 20.0% and (y)
    the number of shares of Common Stock outstanding on the Record Date and
    (ii) the denominator of which shall be equal to the Current Market Price on
    such date; provided that in the event the portion of the cash so
    distributed applicable to one share of Common Stock is equal to or greater
    than the Current Market Price of the Common Stock on the Record Date, in
    lieu of the foregoing adjustment, adequate provision shall be made so that
    each Noteholder shall have the right to receive upon conversion the amount
    of cash such holder would have received had such holder converted each Note
    on the Record Date.  In the event that such dividend or distribution is not
    so paid or made, the Conversion Price shall again be adjusted to be the
    Conversion Price that would then be in effect if such dividend or
    distribution had not been declared.

         (f)  In case a tender offer made by the Company or any of its
    Subsidiaries for all or any portion of the Common Stock shall expire and
    such tender offer (as amended upon the expiration thereof) shall require
    the payment to shareholders (based on the acceptance (up to any maximum
    specified in the terms of the tender offer) of Purchased Shares (as defined
    below)) of an aggregate consideration having a fair market value (as
    determined by the Board of Directors, whose determination shall be
    conclusive and described in a Board Resolution) that combined together with
    (1) the aggregate of the cash plus the fair market value (as determined by
    the Board of Directors, whose determination shall be conclusive and
    described in a Board Resolution), as of the expiration of such tender
    offer, of consideration payable in respect of any other tender offer, by
    the Company or any of its Subsidiaries for all or any portion of the Common
    Stock expiring within the 12 months preceding the 


                                     82

<PAGE>

    expiration of such tender offer, and in respect of which no adjustment 
    pursuant to Section 14.5(f) has been made, and (2) the aggregate 
    amount of any distributions to all holders of the Company's 
    Common Stock made exclusively in cash within 12 months preceding 
    the expiration of such tender offer, and in respect of which 
    no adjustment pursuant to Section 14.5 (e) has been made, exceeds
    20.0% of the product of the Current Market Price (determined as provided in
    Section 14.5(g)) as of the last time (the "Expiration Time") tenders could
    have been made pursuant to such tender offer (as it may be amended) times
    the number of shares of Common Stock outstanding (including any tendered
    shares) on the Expiration Time, then, and in each such case, immediately
    prior to the opening of business on the day after the date of the
    Expiration Time, the Conversion Price shall be adjusted so that the same
    shall equal the price determined by multiplying the Conversion Price in
    effect immediately prior to close of business on the date of the Expiration
    Time by a fraction of which the numerator shall be the number of shares of
    Common Stock outstanding (including any tendered shares) on the Expiration
    Time multiplied by the Current Market Price of the Common Stock on the
    Trading Day next succeeding the Expiration Time and the denominator shall
    be the sum of (x) the fair market value (determined as aforesaid) of the
    aggregate consideration payable to shareholders based on the acceptance (up
    to any maximum specified in the terms of the tender offer) of all shares
    validly tendered and not withdrawn as of the Expiration Time (the shares
    deemed so accepted, up to any such maximum, being referred to as the
    "Purchased Shares") and (y) the product of the number of shares of Common
    Stock outstanding (less any Purchased Shares) on the Expiration Time and
    the Current Market Price of the Common Stock on the Trading Day next
    succeeding the Expiration Time, such reduction to become effective
    immediately prior to the opening of business on the day following the
    Expiration Time.  In the event that the Company is obligated to purchase
    shares pursuant to any such tender offer, but the Company is permanently
    prevented by applicable law from effecting any such purchases or all such
    purchases are rescinded, the Conversion Price shall again be adjusted to be
    the Conversion Price that would then be in effect if such tender offer had
    not been made.

         (g)  For purposes of this Section 14.5, the following terms shall have
    the meaning indicated:

              (i)  "Closing Price" with respect to any securities on any day
         shall mean the closing sale price regular way on such day or, in case
         no such sale takes place on such day, the average of the reported
         closing


                                      83

<PAGE>

         bid and asked prices, regular way, in each case on the New
         York Stock Exchange, or, if such security is not listed or admitted to
         trading on such Exchange, on the principal national security exchange
         or quotation system on which such security is quoted or listed or
         admitted to trading, or, if not quoted or listed or admitted to
         trading on any national securities exchange or quotation system, the
         average of the closing bid and asked prices of such security on the
         over-the-counter market on the day in question as reported by the
         National Quotation Bureau Incorporated, or a similar generally
         accepted reporting service, or if not so available, in such manner as
         furnished by any New York Stock Exchange member firm selected from
         time to time by the Board of Directors for that purpose, or a price
         determined in good faith by the Board of Directors, whose
         determination shall be conclusive and described in a Board Resolution.

              (ii) "Current Market Price" shall mean the average of the daily
         Closing Prices per share of Common Stock for the ten consecutive
         Trading Days immediately prior to the date in question; provided that
         (1) if the "ex" date (as hereinafter defined) for any event (other
         than the issuance or distribution or Change of Control requiring such
         computation) that requires an adjustment to the Conversion Price
         pursuant to Section 14.5(a), (b), (c), (d), (e) or (f) occurs during
         such ten consecutive Trading Days, the Closing Price for each Trading
         Day prior to the "ex" date for such other event shall be adjusted by
         multiplying such Closing Price by the same fraction by which the
         Conversion Price is so required to be adjusted as a result of such
         other event, (2) if the "ex" date for any event (other than the
         issuance, distribution or Change of Control requiring such
         computation) that requires an adjustment to the Conversion Price
         pursuant to Section 14.5(a), (b), (c), (d), (e) or (f) occurs on or
         after the "ex" date for the issuance or distribution requiring such
         computation and prior to the day in question, the Closing Price for
         each Trading Day on and after the "ex" date for such other event shall
         be adjusted by multiplying such Closing Price by the reciprocal of the
         fraction by which the Conversion Price is so required to be adjusted
         as a result of such other event and (3) if the "ex" date for the
         issuance, distribution or Change of Control requiring such computation
         is prior to the day in question, after taking into account any
         adjustment required pursuant to clause (1) or (2) of this proviso, the
         Closing Price for each Trading Day on or after such "ex" date shall be
         adjusted by adding


                                      84

<PAGE>

         thereto the amount of any cash and the fair market value (as 
         determined by the Board of Directors in a manner consistent
         with any determination of such value for purposes of Section 14.5(d)
         or (f), whose determination shall be conclusive and described in a
         Board Resolution) of the evidences of indebtedness, shares of capital
         stock or assets being distributed applicable to one share of Common
         Stock as of the close of business on the day before such "ex" date. 
         For purposes of any computation under Section 14.5(f), the Current
         Market Price of the Common Stock on any date shall be deemed to be the
         average of the daily Closing Prices per share of Common Stock for such
         day and the next two succeeding Trading Days; provided that if the
         "ex" date for any event (other than the tender or exchange offer
         requiring such computation) that requires an adjustment to the
         Conversion Price pursuant to Section 14.5(a), (b), (c), (d), (e) or
         (f) occurs on or after the Expiration Time for the tender or exchange
         offer requiring such computation and prior to the day in question, the
         Closing Price for each Trading Day on and after the "ex" date for such
         other event shall be adjusted by multiplying such Closing Price by the
         reciprocal of the fraction by which the Conversion Price is so
         required to be adjusted as a result of such other event.  For purposes
         of this paragraph, the term "ex" date, (1) when used with respect to
         any issuance or distribution, means the first date on which the Common
         Stock trades regular way on the relevant exchange or in the relevant
         market from which the Closing Price was obtained without the right to
         receive such issuance or distribution, (2) when used with respect to
         any subdivision or combination of shares of Common Stock, means the
         first date on which the Common Stock trades regular way on such
         exchange or in such market after the time at which such subdivision or
         combination becomes effective and (3) when used with respect to any
         tender or exchange offer means the first date on which the Common
         Stock trades regular way on such exchange or in such market after the
         expiration of such offer.  Notwithstanding the foregoing, whenever
         successive adjustments to the Conversion Price are called for pursuant
         to this Section 14.5, such adjustments shall be made to the Current
         Market Price as may be necessary or appropriate to effectuate the
         intent of this Section 14.5 and to avoid unjust or inequitable results
         as determined in good faith by the Board of Directors.


                                      85

<PAGE>

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

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


         (h)  The Company may make such reductions in the Conversion Price, in
    addition to those required by Sections 14.5(a), (b), (c), (d), (e) and (f),
    as the Board of Directors considers to be advisable to avoid or diminish
    any income tax to holders of Common Stock or rights to purchase Common
    Stock resulting from any dividend or distribution of stock (or rights to
    acquire stock) or from any event treated as such for income tax purposes. 
    To the extent permitted by applicable law, the Company from time to time
    may reduce the Conversion Price by any amount for any period of time if the
    period is at least 20 days, the reduction is irrevocable during the period
    and the Board of Directors shall have made a determination that such
    reduction would be in the best interests of the Company, which
    determination shall be conclusive and described in a Board Resolution. 
    Whenever the Conversion Price is reduced pursuant to the preceding
    sentence, the Company shall mail to all holders of record of the Notes a
    notice of the reduction at least 15 days prior to the date the reduced
    Conversion Price takes effect, and such notice shall state the reduced
    Conversion Price and the period it shall be in effect.

         (i)  No adjustment in the Conversion Price shall be required unless
    such adjustment would require an increase or decrease of at least 1% in
    such price; provided that any adjustments that by reason of this Section
    14.5(i) are not required to be made shall be carried forward and taken into
    account in any subsequent adjustment.  All calculations under this Article
    XIV shall be made by the Company and shall be made to the nearest 1/100,000
    (with 0.0000005 being rolled upward).


                                      86

<PAGE>

         No adjustment need be made for rights to purchase Common Stock
    pursuant to a Company plan for reinvestment of dividends or interest.

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

         To the extent the Notes become convertible into cash, assets, property
    or securities (other than Common Stock of the Company), no adjustment need
    be made thereafter as to the cash, assets, property or such securities
    (except as such securities may otherwise by their terms provide), and
    interest shall not accrue on such cash.

         (j)  Whenever the Conversion Price is adjusted as herein provided, the
    Company shall promptly file with the Trustee and any conversion agent other
    than the Trustee an Officers' Certificate setting forth the Conversion
    Price after such adjustment and setting forth a brief statement of the
    facts requiring such adjustment.  Promptly after delivery of such
    certificate, the Company shall prepare a notice of such adjustment of the
    Conversion Price setting forth the adjusted Conversion Price and the date
    on which each adjustment becomes effective and shall mail such notice of
    such adjustment of the Conversion Price to the holder of each Note at his
    last address appearing on the Note register provided for in Section 2.5,
    within 20 days after execution thereof.  Failure to deliver such notice
    shall not effect the legality or validity of any such adjustment.

         (k)  In any case in which this Section 14.5 provides that an
    adjustment shall become effective immediately after a Record Date for an
    event, the Company may defer until the occurrence of such event (i) issuing
    to the holder of any Note converted after such Record Date and before the
    occurrence of such event the additional shares of Common Stock issuable
    upon such conversion by reason of the adjustment required by such event
    over and above the Common Stock issuable upon such conversion before giving
    effect to such adjustment and (ii) paying to such holder any amount in cash
    in lieu of any fraction pursuant to Section 14.3.

         Section 14.6  EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR
SALE.  If any of the following events occur, namely (i) any reclassification or
change of outstanding shares of Common Stock (other than a change in par value,
or to or from no par value, as a result of a subdivision or combination), (ii)
any consolidation, merger or combination of the Company with another corporation
as a result of which holders of Common Stock shall be entitled to receive stock,
securities or other property or assets (including cash) with respect to or in


                                      87

<PAGE>

exchange for such Common Stock or (iii) any sale or conveyance of the properties
and assets of the Company as, or substantially as, an entirety (determined on a
consolidated basis) to any other corporation as a result of which holders of
Common Stock shall be entitled to receive stock, securities or other property or
assets (including cash) with respect to or in exchange for such Common Stock,
then the Company or the successor or purchasing corporation, as the case may be,
shall execute with the Trustee a supplemental indenture (which shall comply with
the Trust Indenture Act as in force at the date of execution of such
supplemental indenture if such supplemental indenture is then required to so
comply) providing that the Notes shall be convertible into the kind and amount
of shares of stock and other securities or property or assets (including cash)
receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance by a holder of a number of shares of Common
Stock issuable upon conversion of such Notes (assuming, for such purposes, a
sufficient number of authorized shares of Common Stock available to convert all
such Notes) immediately prior to such reclassification, change, consolidation,
merger, combination, sale or conveyance, assuming such holder of Common Stock
did not exercise his rights of election, if any, as to the kind or amount of
securities, cash or other property receivable upon such reclassification,
change, consolidation, merger, combination, sale or conveyance (provided that,
if the kind or amount of securities, cash or other property receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance
is not the same for each share of Common Stock in respect of which such rights
of election shall not have been exercised ("non-electing share"), then for the
purposes of this Section 14.6 the kind and amount of securities, cash or other
property receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance for each non-electing share shall be deemed to
be the kind and amount so receivable per share by a plurality of the
non-electing shares).  Such supplemental indenture shall provide for adjustments
that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article XIV.

         The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at his address appearing on the
Note register provided for in Section 2.5, within 20 days after execution
thereof.  Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture.

         The above provisions of this Section 14.6 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

         Section 14.7  TAXES ON SHARES ISSUED.  The issuance of stock
certificates on conversions of Notes shall be made without charge to the
converting Noteholder for any transfer or similar tax in respect of the issue
thereof.  The Company shall not, however, be required to pay any tax that may be
payable in respect of any transfer involved in the issue and delivery of stock
in any name other than that of the holder of any Note converted, and the Company
shall not be required to issue or deliver any such stock certificate unless and
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.

         Section 14.8  RESERVATION OF SHARES; SHARES TO BE FULLY PAID; LISTING
OF COMMON STOCK.  Subject to Section 14.1(b) the Company shall provide, free
from preemptive rights, out of its authorized but unissued shares or shares held
in treasury, sufficient shares to provide for the conversion of the Notes from
time to time as such Notes are presented for conversion.

         Before taking any action that would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Notes, the Company shall take all corporate
action that may, in the opinion of its counsel, be necessary in order that the
Company may validly and legally issue shares of such Common Stock at such
adjusted Conversion Price.

         The Company covenants that all shares of Common Stock that may be
issued upon conversion of Notes shall, upon issuance, be fully paid and
nonassessable by the Company and free from all taxes, liens and charges with
respect to the issuance thereof.

         The Company further covenants that it shall, if permitted by the rules
of the Nasdaq Stock Market, list and keep listed, so long as the Common Stock
shall be so listed on such exchange, all Common Stock issuable upon conversion
of the Notes.

         Section 14.9  RESPONSIBILITY OF TRUSTEE.  The Trustee and any other
conversion agent shall not at any time be under any duty or responsibility to
any holder of Notes to determine whether any facts exist that may require any
adjustment of the Conversion Price or notice thereof, or with respect to the
nature, accuracy or extent or calculation of any such adjustment when made, or
with respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same.  The Trustee and any other
conversion agent shall not be accountable with respect to the validity or value
(or the kind or amount) of any shares of Common Stock, or of any securities or
property, that may at any time be issued or delivered upon the conversion of any
Note; and the Trustee and any other conversion


                                      89

<PAGE>

agent make no representations with respect thereto or actions or omissions by 
the Company in connection with this Article XIV.  Subject to the provisions 
of Section 7.1, neither the Trustee nor any conversion agent shall be 
responsible for any failure of the Company to issue, transfer or deliver any 
shares of Common Stock or stock certificates or other securities or property 
or cash upon the surrender of any Note for the purpose of conversion or to 
comply with any of the duties, responsibilities or covenants of the Company 
contained in this Article XIV.  Without limiting the generality of the 
foregoing, neither the Trustee nor any conversion agent shall be under any 
responsibility to determine whether a supplemental indenture under Section 
14.6 hereof need to be entered into or the correctness of any provisions 
contained in any supplemental indenture entered into pursuant to Section 14.6 
relating either to the kind or amount of shares of stock or securities or 
property (including cash) receivable by Noteholders upon the conversion of 
their Notes after any event referred to in such Section 14.6 or to any 
adjustment to be made with respect thereto, and may accept as conclusive 
evidence of the correctness of any such provisions, and shall be protected in 
relying upon, the Officers' Certificate (which the Company shall be obligated 
to file with the Trustee prior to the execution of any such supplemental 
indenture) with respect thereto.

         Section 14.10  NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS.  In case:

         (a)  the Company makes any distribution or dividend that would require
    an adjustment in the Conversion Price pursuant to Section 14.5; or

         (b)  the Company takes any action that would require a supplemental
    indenture pursuant to Section 14.6; or

         (c)  of the voluntary or involuntary dissolution, liquidation or
    winding-up of the Company,

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Notes at his address appearing on the Note register, as promptly as
possible but in any event at least 15 days prior to the applicable date
hereinafter specified, a notice stating (x) the date on which a record date is
to be taken for the purpose of such dividend, distribution, rights, options or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of record to be entitled to such dividend, distribution, rights,
options or warrants are to be determined or (y) the date on which such
reclassification, change, consolidation, merger, sale, conveyance, transfer,
dissolution, liquidation or winding-up is expected to become effective or occur
and the date as of which it is expected that holders of record of Common Stock
shall be entitled to exchange


                                      90
<PAGE>

their Common Stock for securities or other property deliverable upon such 
reclassification, change, consolidation, merger, sale, conveyance, transfer, 
dissolution, liquidation or winding-up.  Neither the failure to give such 
notice nor any defect therein shall affect the legality or validity of the 
proceedings referenced in clauses (a) through (c) of this Section 14.10.


                                      ARTICLE XV

                                    SUBORDINATION


         Section 15.1  AGREEMENT TO SUBORDINATE.  The Company agrees, and each
Noteholder by accepting a Note agrees, that the indebtedness evidenced by the
Notes is subordinated in right of payment, to the extent and in the manner
provided in this Article XV, to the prior payment in full of all Senior
Indebtedness and that the subordination is for the benefit of the holders of
Senior Indebtedness.

         Section 15.2  CERTAIN DEFINITIONS.  For purposes of this Article XV,
the following terms shall have the meaning indicated:

         (1)  "Representative" shall mean a duly authorized indenture trustee
    or other trustee, agent or representative for any Senior Indebtedness.

         (2)  "Senior Indebtedness" with respect to the Notes means the
    principal of, premium, if any, and interest on, and any fees, costs,
    expenses and any other amounts (including indemnity payments) related to
    the following, whether outstanding on the date hereof or hereafter incurred
    or created:  (a) indebtedness, matured or unmatured, whether or not
    contingent, of the Company for money borrowed evidenced by notes or other
    written obligations, (b) any interest rate contract, interest rate swap
    agreement or other similar agreement or arrangement designed to protect the
    Company or any of its Subsidiaries against fluctuations in interest rates,
    (c) indebtedness, matured or unmatured, whether or not contingent, of the
    Company evidenced by notes, debentures, bonds or similar instruments or
    letters of credit (or reimbursement agreements in respect thereof), (d)
    obligations of the Company as lessee under capitalized leases and under
    leases of property made as part of any sale and leaseback transactions, (e)
    indebtedness of others of any of the kinds described in the preceding
    clauses (a) through (d) assumed or guaranteed by the Company and (f)
    renewals, extensions, modifications, amendments, and refundings of, and
    indebtedness and obligations of a


                                      91

<PAGE>

    successor person issued in exchange for or in replacement of, indebtedness 
    or obligations of the kinds described in the preceding clauses (a) through 
    (f), unless the agreement pursuant to which any such indebtedness described
    in clauses (a) through (f) is created, issued, assumed or guaranteed 
    expressly provides that such indebtedness is not senior or superior in 
    right of payment to the Notes; provided that the following shall not 
    constitute Senior Indebtedness: (i) any indebtedness or obligation of the 
    Company in respect of the Notes, (ii) any indebtedness of the Company to 
    any of its Subsidiaries or other Affiliates; (iii) any indebtedness that is
    subordinated or junior in any respect to any other indebtedness of the 
    Company other than Senior Indebtedness; and (iv) any indebtedness incurred 
    for the purchase of goods or materials in the ordinary course of business.

         For the purposes of this Indenture, Senior Indebtedness shall not be
deemed to have been paid in full until the holders of the Senior Indebtedness
shall have indefeasibly received payment in full in cash of all Senior
Indebtedness; provided that if any holder of Senior Indebtedness agrees to
accept payment in full of such Senior Indebtedness for consideration other than
cash, such holder shall be deemed to have indefeasibly received payment in full
of such Senior Indebtedness.  The provisions of this Article XV shall continue
to be effective or be reinstated, as the case may be, if at any time any 
payment of any of the Senior Indebtedness is rescinded or must otherwise be 
returned by any holder of Senior Indebtedness upon the insolvency, bankruptcy 
or organization of the Company or otherwise, all as though such payment had not
been made.

         A distribution may consist of cash, securities or other property, by
set-off or otherwise.

         Section 15.3  LIQUIDATION; DISSOLUTION; BANKRUPTCY.  Upon any
distribution to creditors of the Company in a liquidation or dissolution of the
Company or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Company or its property, in an assignment for the
benefit of creditors or any marshalling of the Company's assets and 
liabilities, (a) holders of all Senior Indebtedness shall first be entitled to 
receive payment in full of all amounts due or to become due thereon before 
Noteholders shall be entitled to receive any payment with respect to the 
principal of, premium, if any, or interest on the Notes (except that 
Noteholders may receive securities that are subordinated to at least the same 
extent as the Notes to Senior Indebtedness and any securities issued in 
exchange for Senior Indebtedness) and (b) until all Senior Indebtedness (as 
provided in clause (a) above) is paid in full, any distribution to which 
Noteholders would be entitled but for this Article shall be made to holders 
of Senior Indebtedness


                                      92

<PAGE>

(except that Noteholders may receive securities that are subordinated to at 
least the same extent as the Notes to (x) Senior  Indebtedness and (y) any 
securities issued in exchange for Senior  Indebtedness), as their interests 
may appear.  

         Section 15.4  DEFAULT ON SENIOR INDEBTEDNESS.  The Company may not
make any payment upon or in respect of the Notes (except in such subordinated
securities) and may not acquire from the Trustee or any Noteholder any Note for
cash or property (other than securities that are subordinated to at least the
same extent as the Note to (i) Senior Indebtedness and (ii) any securities
issued in exchange for Senior Indebtedness) until all Senior Indebtedness has
been paid in full if:

         (a)  a default in the payment of the principal of, premium, if
    any, or interest on Senior Indebtedness occurs and is continuing
    beyond any applicable period of grace (a "Payment Default"); or 

         (b)  a default, other than a Payment Default on Senior
    Indebtedness occurs and is continuing that permits holders of the
    Senior Indebtedness as to which such default relates to accelerate its
    maturity (a "Nonpayment Default") and the Trustee receives a notice of
    the default (a "Payment Blockage Notice") from the Representative or
    Representatives of holders of at least a majority in principal amount
    of Senior Indebtedness then outstanding.  No Nonpayment Default that
    existed or was continuing on the date of delivery of any such Payment
    Blockage Notice to the Trustee shall be, or be made, the basis for a
    subsequent Payment Blockage Notice unless such default shall have been
    cured or waived for a period of not less than 180 days.  No new period
    of payment blockage may be commenced within 360 days after the receipt
    by the Trustee of any prior Payment Blockage Notice.

         The Company, with notice and evidence of the occurrence of (c) or (d)
provided to the Trustee, may and shall resume payments on and distributions in
respect of the Notes and may acquire them upon the earlier of:

         (c)  in the case of a Payment Default, upon the date on which the
    default is cured or waived, or

         (d)  in the case of a default other than a NonPayment Default: 179
    days after the date on which the applicable Payment Blockage Notice is
    received, unless the maturity of such Senior Indebtedness has been
    accelerated,


                                      93

<PAGE>

if this Article XV otherwise permits the payment, distribution or acquisition 
at the time of such payment or acquisition.

         Section 15.5  WHEN DISTRIBUTION MUST BE PAID OVER.  In the event that
the Trustee (or paying agent if other than the Trustee) or any Noteholder
receives any payment of principal or interest with respect to the Notes at a
time when such payment is prohibited by Section 15.3 or 15.4 hereof, such
payment shall be held by the Trustee (or paying agent if other than the 
Trustee) or such Noteholder, in trust for the benefit of, and immediately 
shall be paid over and delivered, upon written request, to, the holders of 
Senior Indebtedness as their interests may appear or their Representative 
under the indenture or other agreement (if any) pursuant to which Senior 
Indebtedness may have been issued, as their respective interests may appear, 
for application to the payment of all Senior Indebtedness remaining unpaid 
to the extent necessary to pay all Senior Indebtedness in full in accordance 
with its terms, after giving effect to any concurrent payment or 
distribution to or for the holders of Senior Indebtedness.

         With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform only such obligations on the part of the Trustee as are
specifically set forth in this Article XV, and no implied covenants or
obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee.  The Trustee shall not be deemed to 
owe any fiduciary duty to the holders of Senior Indebtedness and shall not 
be liable to any such holders if the Trustee shall pay over or distribute to 
or on behalf of Noteholders or the Company or any other person money or 
assets to which any holders of Senior Indebtedness shall be entitled by 
virtue of this Article XV, except if such payment is made as a result of the 
willful misconduct or gross negligence of the Trustee.

         Section 15.6  NOTICE BY COMPANY.  The Company shall promptly notify
the Trustee and the paying agent in writing of any facts known to the Company
that would cause a payment of any principal or interest with respect to the
Notes to violate this Article XV, but failure to give such notice shall not
affect the subordination of the Notes to the Senior Indebtedness as provided in
this Article XV.

         Section 15.7  SUBROGATION.  Until all Senior Indebtedness is paid in
full and until the Notes are paid in full, Noteholders shall be subrogated
(equally and ratably with all other indebtedness pari passu with the Notes) to
the rights of holders of Senior Indebtedness to receive distributions 
applicable to Senior Indebtedness to the extent that distributions otherwise 
payable to the Noteholders have been applied to the payment of Senior 
Indebtedness.  A distribution made under this Article XV to holders of 
Senior Indebtedness that


                                      94

<PAGE>

otherwise would have been made to Noteholders is not, as between the Company 
and Noteholders, a payment by the Company on the Notes. 

         Section 15.8  RELATIVE RIGHTS.  This Article XV defines the relative
rights of Noteholders and holders of Senior Indebtedness.  Nothing in this
Indenture shall:

         (a)  impair, as between the Company and the Noteholders, the
    obligation of the Company, which is absolute and unconditional, to pay
    principal of, premium, if any, and interest on the Notes in accordance with
    their terms;

         (b)  affect the relative rights of Noteholders and creditors of the
    Company other than their rights in relation to holders of Senior
    Indebtedness; or

         (c)  prevent the Trustee or any Noteholder from exercising its
    available remedies upon a default or Event of Default, subject to the
    rights of holders and owners of Senior Indebtedness to receive
    distributions and payments otherwise payable to Noteholders.

         If the Company fails because of this Article XV to pay principal of,
premium, if any, or interest on a Note on the due date, the failure is still a
default or Event of Default. 

         Section 15.9  SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.  No right
of any holder of Senior Indebtedness to enforce the subordination of the
indebtedness evidenced by the Notes shall be impaired by any act or failure to
act by the Company or any holder of Notes or by the failure of the Company or
any holder of Notes to comply with this Indenture. 

         Section 15.10  DISTRIBUTION OR NOTICE TO REPRESENTATIVE.  Whenever a
distribution is to be made or a notice given to holders of Senior Indebtedness,
the distribution may be made and the notice given to their Representative. 

         Upon any payment or distribution of assets of the Company referred to
in this Article XV, the Trustee and the Noteholders shall be entitled to rely
upon any order or decree made by any court of competent jurisdiction or upon 
any certificate of such Representative or of the liquidating trustee or agent 
or other person making any distribution to the Trustee or to the Noteholders 
for the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or


                                      95

<PAGE>

distributed thereon and all other facts pertinent thereto or to this Article
XV.

         Section 15.11  RIGHTS OF TRUSTEE AND PAYING AGENT.  Notwithstanding
the provisions of this Article XV or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment or distribution by the Trustee, and 
the Trustee and the paying agent may continue to make payments on the Notes, 
unless the Trustee shall have received at its Corporate Trust Office at least 
three Business Days prior to the date of such payment written notice of facts 
that would cause the payment of any principal, premium, if any, and interest 
with respect to the Notes to violate this Article XV.  Only the Company or a
Representative may give the notice.  Nothing in this Article XV shall impair 
the claims of, or payments to, the Trustee under or pursuant to Section 7.6 
hereof.

         The Trustee shall be entitled to rely on the delivery to it of a
written notice by a person representing such person to be a holder of Senior
Indebtedness (or a trustee or agent on behalf of such holder) to establish that
such notice has been given by a holder of Senior Indebtedness (or a trustee or
agent on behalf of any such holder).  In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of 
any person as a holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article XV, the Trustee may request such person 
to furnish evidence to the reasonable satisfaction of the Trustee as to the 
amount of Senior Indebtedness held by such person, the extent to which such 
person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such person under this Article XV, and if such
evidence is not furnished, the Trustee may defer any payment which it may be
required to make for the benefit of such person pursuant to the terms of this
Indenture pending judicial determination as to the rights of such person to
receive such payment.

         The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee.  Any
paying agent, any authenticating agent, any conversion agent, any Note 
registrar and their successors may do the same with like rights.

         Section 15.12  AUTHORIZATION TO EFFECT SUBORDINATION.  Each holder of
a Note by the holder's acceptance thereof authorizes and directs the Trustee on
the holder's behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article XV and appoints the
Trustee to act as the holder's attorney-in-fact for any and all such purposes.
Without limiting the foregoing, each


                                      96

<PAGE>

Representative is hereby irrevocably authorized and empowered (in its own 
name or in the name of the Noteholders or the Trustee or otherwise), but 
shall have no obligation, to demand, sue for, collect and receive every 
payment or distribution referred to in Section 15.3 above and give 
acquittance therefor and to file claims and proofs of claim and take such 
other action as it may deem necessary or advisable for the exercise or 
enforcement of any of the rights or interests of the holders or owners of 
the Senior Indebtedness hereunder; provided that for purposes of this Section 
15.12 holders or owners of Senior Indebtedness may act only through such
Representative.

         Section 15.13  CONVERSIONS NOT DEEMED PAYMENT.  For the purposes of
this Article XV only, the issuance and delivery of Common Stock upon conversion
of the Notes in accordance with Article XIV shall not be deemed to constitute a
payment or distribution on account of the principal of or interest on the Notes
or on account of the purchase or other acquisition of Notes.  Nothing contained
in this Article or elsewhere in this Indenture or in the Notes is intended to 
or shall impair, as among the Company, its creditors other than holders of 
Senior Indebtedness and the holders, the right, which is absolute and 
unconditional, of the holder of any Note to convert such Note in accordance 
with Article XIV.

         Section 15.14  AMENDMENTS.  The provisions of this Article XV shall
not be amended or modified without the written consent of the holders of Senior
Indebtedness.


                                     ARTICLE XVI

effect by the


                                      97

         Section 16.10  TRUST INDENTURE ACT.  This Indenture is hereby made
subject to, and shall be governed by, the provisions of the Trust Indenture Act
required to be part of and to govern indentures qualified under the Trust
Indenture Act.

         Section 16.11  TRUST INDENTURE ACT CONTROLS.  If any provision of this
Indenture limits, qualifies, or conflicts with the duties imposed by operation
of the Trust Indenture Act, the imposed duties, upon qualification of this

the Notes, expressed or implied, shall give to any person, other than the
parties hereto, any paying agent, any authenticating agent, any conversion

to its direction in the authentication and delivery of Notes in connection with
the original issuance thereof and transfers and exchanges of Notes hereunder,
including under Sections 2.4, 2.5, 2.6, 2.7 and 3.3, as fully to all intents 
and purposes as though the authenticating agent had been expressly authorized 
by this Indenture and those Sections to authenticate and deliver Notes.  For 
all purposes of this Indenture, the authentication and delivery of Notes by the
authenticating agent shall be deemed to be authentication and delivery of such
Notes "by the Trustee" and a certificate of authentication executed on behalf 
of the Trustee by an authenticating agent shall be deemed to satisfy any

of any authenticating agent, shall be the successor of the


                                      100

<PAGE>

authenticating agent hereunder, if such successor company is otherwise 
eligible under this Section, without the execution or filing of any paper or 
any further act on the part of the parties hereto or the authenticating 
agent or such successor company.

notice of resignation to the Trustee and to the Company.  The Trustee may at 
any time terminate the agency of any authenticating agent by giving written 
notice of termination to such authenticating agent and to the Company.  Upon 
receiving such a notice of resignation or upon such a termination, or in case 
at any time any authenticating agent shall cease to be eligible under this 
Section, the Trustee shall promptly appoint a successor authenticating agent 
(which may be the Trustee), shall give written notice of such appointment to 
the Company and shall mail notice of such appointment to all holders of Notes 
as the names and addresses of such holders appear on the Note register.

         The Company agrees to pay to the authenticating agent from time to
time reasonable compensation for its services.

         The provisions of Sections 7.3, 7.4, 7.5, 8.3 and this Section 16.14
shall be applicable to any authenticating agent.

         Section 16.15  EXECUTION IN COUNTERPARTS.  This Indenture may be

         PENN TREATY AMERICAN CORPORATION, a corporation duly organized and
validly existing under the laws of the Commonwealth of Pennsylvania (the
"Company"), which term includes any Successor Company under the Indenture
referred to on the reverse hereof, for value received hereby promises to pay to
___________ ________________, or registered assigns, the principal sum of
______________________________________ Dollars on December 1, 2003 at the office
or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York, or, at the option of the holder of this Note,
at the Corporate Trust Office of the Trustee, in such coin or currency of the
United States of America as at the time of payment shall be legal tender for the
payment of public and private debts, and to pay interest, semi-annually on
June 1 and December 1 of each year (each an "Interest Payment Date"), commencing
June 1, 1997, on said principal sum at said office or agency, in like coin or
currency, at the rate per annum specified in the title of this Note, from
November 26, 1996 or the most recent Interest Payment Date, as the case may be,
next preceding the date of this Note to which interest has been paid or duly
provided for, unless the date hereof is a date to which interest has been paid
or duly provided for, in which case from the date of this Note, or unless no
interest has been paid or duly provided for on the Notes, in which case from
November 26, 1996, until payment of said principal sum has been made or duly
provided for.  Any interest on any Note that is payable, but is not punctually
paid or duly provided for on said June 1 or December 1 (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Noteholder on the relevant
record date by virtue of his having been such Noteholder; and such Defaulted
Interest shall be paid


                                      A-2

<PAGE>

by the Company, at its election in each case, either (i) by notifying the 
Trustee of a special record date, the amount of interest to be paid on such 
special record date and the date of payment (not more than 25 days after 
receipt by the Trustee of such interest, unless the Trustee shall consent to 
an earlier date) and depositing with the Trustee an amount of money equal to 
the aggregate amount to be paid in respect of such Defaulted Interest on 
making arrangements satisfactory to the Trustee for such deposit or (ii) in 
any lawful manner not inconsistent with the requirements of any securities 
exchange on which the Notes may be listed and upon notice requested by such 
exchange, if, after notice to the Trustee, the Trustee deems such manner of 
payment to be practicable.  The interest so payable on any June 1 or December 
1 will be paid to the person in whose name this Note (or one or more 
Predecessor Notes) is registered at the close of business on the record date, 
which shall be the May 15 or November 15 (whether or not a Business Day) next 
preceding such June 1 or December 1, respectively; provided that any such 
interest not punctually paid or duly provided for shall be payable as 
provided in the Indenture.  Interest shall be paid by check mailed to the 
registered holder at the registered address of such person unless other 
arrangements are made in accordance with the provisions of the Indenture.

         Reference is made to the further provisions of this Note set forth on
the reverse hereof, including, without limitation, provisions giving the holder
of this Note the right to convert this Note into Common Stock of the Company
(or, under certain circumstances specified in the Indenture, into an amount of
cash as set forth in the Indenture) on the terms and subject to the limitations
referred to on the reverse hereof and as more fully specified in the Indenture. 
Such further provisions shall for all purposes have the same effect as though
fully set forth at this place.

         This Note shall not be valid or become obligatory for any purpose
until the certificate of authentication hereon shall have been manually signed
by the Trustee, or a duly authorized authenticating agent under the Indenture.

                              [FORM OF REVERSE OF NOTE]

                           PENN TREATY AMERICAN CORPORATION

                    6-1/4% Convertible Subordinated Notes Due 2003

         This Note is one of a duly authorized issue of Notes of the Company,
designated as its 6-1/4% Convertible Subordinated Notes Due 2003 (herein called
the "Notes"), limited to the aggregate principal amount of $74,750,000 all
issued or to be issued under and pursuant to an Indenture dated as of November
26, 1996 (the "Indenture"), between the Company and First Union National Bank,
as trustee (the "Trustee"), to which Indenture and all indentures supplemental
thereto reference is hereby made for a complete description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Company and the holders of the Notes.  Each Note is subject to, and
qualified by, all such terms as set forth in the Indenture certain of which are
summarized hereon and each holder of a Note is referred to the corresponding
provisions of the Indenture for a complete statement of such terms.  To the
extent that there is any inconsistency between the summary provisions set forth
in the Notes and the Indenture, the provisions of the Indenture shall govern. 
Capitalized terms used but not defined in this Note shall have the meanings
ascribed to them in the Indenture.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest on all Notes may be declared, and upon said declaration shall become,
due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

         The payment of principal of, premium, if any, and interest on the
Notes will, to the extent set forth in the Indenture, be subordinated in right
of payment to the prior payment in full of all Senior Indebtedness (as defined
in the Indenture).  Upon any distribution to creditors of the Company in a
liquidation or dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding related to the Company or its
property, in an assignment for the benefit of creditors or any marshalling of
the Company's assets and liabilities, the holders of all Senior Indebtedness
will first be entitled to receive payment in full of all amounts due or to
become due thereon before the holders of the Notes will be entitled to receive
any payment in respect of the principal of, premium, if any, or interest on the
Notes (except that holders of Notes may receive securities that are subordinated
at least to the same extent as the Notes to Senior Indebtedness and any
securities issued in exchange for Senior Indebtedness).


                                      A-5

<PAGE>

         The Company also may not make any payment upon or in respect of the
Notes (except in such subordinated securities) and may not acquire from the
Trustee or the holder of any Note for cash or property (other than securities
subordinated to at least the same extent as the Note to (i) all Senior
Indebtedness and (ii) any securities issued in exchange for Senior Indebtedness)
until all Senior Indebtedness has been paid in full if (a) a default in the
payment of the principal of, premium, if any, or interest on Senior Indebtedness
occurs and is continuing beyond any applicable period of grace or (b) any other
default occurs and is continuing with respect to Senior Indebtedness that
permits holders of the Senior Indebtedness as to which such default relates to
accelerate its maturity and the Trustee receives a notice of such default (a
"Payment Blockage Notice") from the representative or representatives of holders
of at least a majority in principal amount of Senior Indebtedness then
outstanding.  Payments on the Notes may and shall be resumed (i) in the case of
a Payment Default, upon the date on which such default is cured or waived, or
(ii) in the case of a Nonpayment Default, 179 days after the date on which the
applicable Payment Blockage Notice is received, unless the maturity of any
Senior Indebtedness has been accelerated.  No new period of payment blockage may
be commenced within 360 days after the receipt by the Trustee of any prior
Payment Blockage Notice.  No default, other than a Nonpayment Default, that
existed or was continuing on the date of delivery of any Payment Blockage Notice
to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage
Notice unless such default shall have been cured or waived for a period of not
less than 180 days.

         In the event that the Trustee (or paying agent if other than the
Trustee) or any holder of the Notes receives any payment of principal or
interest with respect to the Notes at a time when such payment is prohibited
under the Indenture, such payment shall be held in trust for the benefit of, and
immediately shall be paid over and delivered to, the holders of Senior
Indebtedness or their representative as their respective interests may appear. 
After all Senior Indebtedness is paid in full and until the Notes are paid in
full, the holders of the Notes shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Notes have
been applied to the payment of Senior Indebtedness.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, evidenced as in
the Indenture provided, to execute supplemental indentures adding any provisions
to or changing in any manner or eliminating any of the provisions of


                                      A-6

<PAGE>

the Indenture or of any supplemental indenture or modifying in any manner the 
rights of the holders of the Notes; provided that no such supplemental 
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate 
or extend the time of payment of interest thereon, or reduce the principal 
amount thereof or premium, if any, thereon, or reduce any amount payable on 
redemption thereof, alter the obligation of the Company to repurchase the 
Notes at the option of the holders upon the occurrence of a Change of 
Control, or impair or affect the right of any Noteholder to institute suit 
for the payment thereof, or make the principal thereof or interest or 
premium, if any, thereon payable in any coin or currency other than that 
provided in the Notes, modify the subordination provisions in a manner 
adverse to the holders of the Notes, or impair the right to convert the Notes 
into Common Stock subject to the terms set forth in the Indenture without the 
consent of the holder of each Note so affected or (ii) reduce the aforesaid 
percentage of Notes, the holders of which are required to consent to any such 
supplemental indenture, without the consent of the holders of all Notes then 
outstanding.  The Company and the Trustee may amend or supplement the 
Indenture without notice to or consent of any holder of Notes in certain 
events specified in the Indenture.  It is also provided in the Indenture 
that, prior to any declaration accelerating the maturity of the Notes, the 
holders of a majority in aggregate principal amount of the Notes at the time 
outstanding may on behalf of the holders of all of the Notes waive any past 
default or Event of Default under the Indenture and its consequences except a 
default in the payment of interest or any premium on or the principal of any 
of the Notes, a failure by the Company to convert any Notes into Common Stock 
of the Company, unless otherwise excused pursuant to the terms of the 
Indenture, or a default in respect of a covenant or provision of the 
Indenture that under Article X thereof cannot be modified or amended without 
the consent of the holders of all Notes then outstanding.  Any such consent 
or waiver by the holder of this Note (unless revoked as provided in the 
Indenture) shall be conclusive and binding upon such holder and upon all 
future holders and owners of this Note and any Notes that may be issued in 
exchange or substitution hereof, irrespective of whether or not any notation 
thereof is made upon this Note or such other Notes.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the place, at the respective times, at the rate and in the coin
or currency herein prescribed.


                                      A-7

<PAGE>

         Interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months.

         The Notes are issuable in registered form without coupons in
denominations of $1,000 principal amount and integral multiples thereof.  At the
office or agency of the Company referred to on the face hereof, and in the
manner and subject to the limitations provided in the Indenture, without payment
of any service charge but with payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any
registration or exchange of Notes, Notes may be exchanged for a like aggregate
principal amount of Notes of other authorized denominations.

         The Notes are not redeemable at the option of the Company prior to
December 3, 1999.  At any time on or after that date, the Notes may be redeemed
at the Company's option, upon notice as set forth in the Indenture, in whole at
any time or in part from time to time, at the following prices (expressed in
percentages of the principal amount), together with accrued interest to the date
fixed for redemption if redeemed during the 12-month period beginning:

                        DATE                REDEMPTION PRICE
                        ----                ----------------

                   December 3, 1999              103.13%
                   December 1, 2000              102.08%
                   December 1, 2001              101.04%

and 100% on or after December 1, 2002; provided that if the date fixed for
redemption is a date on or after the record date and on or before the next
following Interest Payment Date, then the interest payable on such date shall be
paid to the holder of record on the next preceding May 15 or November 15,
respectively.

         If a Change of Control (as defined in the Indenture) shall occur at
any time, then each holder of Notes shall have the right to require that the
Company repurchase such holder's Notes in whole or in part in integral multiples
of $1,000, at a purchase price in cash in an amount equal to 101% of the
principal amount of such Notes, plus accrued and unpaid interest, if any, to the
repurchase date pursuant to an offer to be made by the Company and in accordance
with the procedures set forth in the Indenture.

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after 90 days following the latest date of
original issuance of the Notes and prior to the close of business on November
28, 2003, subject to prior redemption or repurchase, or, as to all or any
portion hereof called for redemption, prior to the close of business one


                                      A-8

<PAGE>

business day before the date fixed for redemption (unless the Company shall
default in payment due upon redemption thereof), to convert the principal hereof
or any portion of such principal that is $1,000 or an integral multiple thereof,
into that number of fully paid and non-assessable shares of the Company's Common
Stock, as said shares shall be constituted at the date of conversion, obtained
by dividing the principal amount of this Note or portion thereof to be converted
by the conversion price of $28.44 per share or such conversion price as adjusted
from time to time as provided in the Indenture, upon surrender of this Note,
together with a conversion notice as provided in the Indenture, to the Company
at the office or agency of the Company maintained for that purpose in the
Borough of Manhattan, The City of New York, or at the option of such holder, the
Corporate Trust Office of the Trustee, and, unless the shares issuable on
conversion are to be issued in the same name as this Note, duly endorsed by, or
accompanied by instruments of transfer in form satisfactory to the Company duly
executed by, the holder or by his duly authorized attorney.  

         Except as described in the Indenture, no adjustment will be made on
conversion of any Notes for interest accrued thereon or for dividends paid on
any Common Stock issued.  A Holder of Notes at the close of business on a record
date will be entitled to receive the interest payable on such Notes on the
corresponding interest payment date.  However, Notes surrendered for conversion
during the period from the close of business on a record date to the opening of
business on the next succeeding interest payment date must be accompanied by
funds equal to the interest payable on such succeeding interest payment date on
the principal amount so converted (unless such Note or portion thereof being
converted is called for redemption on a redemption date during the period from
the close of business on or after any record date to the close of business on
the business day following the corresponding interest payment date).  The
interest payment with respect to a Note called for redemption on a date between
the close of business on any record date for the payment of interest to the
close of business on the business day following the corresponding interest
payment date and surrendered for conversion during that period will be payable
on the corresponding interest payment date to the registered Holder at the close
of business on that record date (notwithstanding the conversion of such Note
before the corresponding interest payment date).  A Holder of Notes who elects
to convert during that period need not include funds equal to the interest paid.
The Company is not required to issue fractional shares of Common Stock upon
conversion of Notes and, in lieu thereof, will pay a cash adjustment based upon
the closing price of the Common Stock on the last business day prior to the date
of conversion.


                                      A-9

<PAGE>

         In the event a holder desires to convert all or any portion of its
Notes into shares of Common Stock and the Company does not have authorized a
sufficient number of shares of Common Stock for such conversion, in lieu of
delivering shares of Common Stock (or other securities into which the Notes are
then convertible) upon conversion of that portion of such holder's Notes for
which there is an insufficient number of shares of Common Stock (the "Cash
Equivalent Notes") pursuant to the provisions of the Indenture, the Company will
pay to the holder converting the Cash Equivalent Notes who properly exercises
the conversion privilege, as set forth in the Indenture, an amount in cash equal
to the Market Cash Conversion Price (as defined in the Indenture) of the shares
of Common Stock into which such Cash Equivalent Notes are then convertible.

         Upon due presentment for registration of transfer of this Note at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, or at the option of the holder of this Note, at the Corporate Trust Office
of the Trustee, a new Note or Notes of authorized denominations for an equal
aggregate principal amount will be issued to the transferee in exchange thereof,
subject to the conditions and limitations provided in the Indenture, without
charge except for any tax or other governmental charge imposed in connection
therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,
any conversion agent and any Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Note (whether or not this Note shall
be overdue and notwithstanding any notation of ownership or other writing hereon
made by anyone other than the Company or any Note registrar), for the purpose of
receiving payment hereof, or on account hereof, for the conversion hereof and
for all other purposes, and neither the Company nor the Trustee nor any other
authenticating agent nor any paying agent nor any other conversion agent nor any
Note registrar shall be affected by any notice to the contrary.  All payments
made to or upon the order of such registered holder shall, to the extent of the
sum or sums paid, satisfy and discharge liability for monies payable on this
Note.

         No recourse for the payment of the principal of or any premium or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall
be had against any incorporator, shareholder, officer or director, as such,
past, present or future, of the Company or of any Successor Company, either
directly or through the Company or any Successor Company, whether by virtue of
any constitution, statute or rule of law or by the enforcement of any assessment
or penalty

or otherwise, all such liability being, by the acceptance hereof and as part 
of the consideration for the issue hereof, expressly waived and released.

         PENN TREATY AMERICAN CORPORATION, a corporation duly organized and
validly existing under the laws of the Commonwealth of Pennsylvania (the
"Company"), which term includes any Successor Company under the Indenture
referred to on the reverse hereof, for value received hereby promises to pay to
_______________________________, or registered assigns, the principal sum of
_________________________________Dollars (subject to adjustment as set forth in
the next paragraph hereof) on December 1, 2003, at the office or agency of the
Company maintained for that purpose in the Borough of Manhattan, The City of New

the option of the holder of this Restricted Global Note, at the Corporate 
Trust Office of the Trustee, in such coin or currency of the United States of 
America as at the time of payment shall be legal tender for the payment of 
public and private debts, and to pay interest, semi-annually on June 1 and 
December 1 of each year (each an "Interest Payment Date"), commencing June 1, 
1997, on said principal sum at said office or agency, in like coin or 
currency, at the rate per annum specified in the title of this Restricted 
Global Note, from November 26, 1996 or the most recent Interest Payment Date, 
as the case may be, next preceding the date of this Restricted Global Note to 
which interest has been paid or duly provided for, unless the date hereof is 
a date to which interest has been paid or duly provided for, in which case 
from the date of this Restricted Global Note, or unless no interest has been 
paid or duly provided for on the Notes, in which case from November 26, 1996, 
until payment of said principal sum has been made or duly provided for.  Any 
interest on any Note that is payable, but is not punctually paid or duly 
provided for on said June 1 or December 1 (herein called "Defaulted 
Interest") shall forthwith cease to be payable to the Noteholder on the 
relevant record date by virtue of his having been such Noteholder; and such 
Defaulted Interest shall be paid by the Company, at its election in each 
case, either (i) by notifying the Trustee of a special record date, the 
amount of interest to be paid on such special record date and the date of 
payment (not more than 25 days after receipt by the Trustee of such interest, 
unless the Trustee shall consent to an earlier date) and depositing with the 
Trustee an amount of money equal to the aggregate amount to be paid in 
respect of such Defaulted Interest on making arrangements satisfactory to the 
Trustee for such deposit or (ii) in any lawful manner not inconsistent with 
the requirements of any securities exchange on which the Notes may be listed 
and upon notice requested by such exchange, if, after notice to the Trustee, 
the Trustee deems such manner of payment to be practicable.  The interest so 
payable on any June 1 or December 1 will be paid to the person in whose name 
this Restricted Global Note (or one or more Predecessor Notes) is registered 
at the close of business on the record date, which shall be the May 15 or 
November 15 (whether or not a Business Day) next preceding such June 1 or 
December 1, respectively; provided that any such interest not punctually paid 
or duly provided for shall be payable as provided in the Indenture.  Interest 
shall be paid by check mailed to the registered holder at the registered 
address of such person unless other arrangements are made in accordance with 
the provisions of the Indenture.

         The aggregate principal amount of this Restricted Global Note
represented hereby may from time to time be reduced or increased to reflect
exchanges of a part of this Restricted Global Note for interests in the
Regulation S Global Note or

Global Note effected by delivery of interests in the Regulation S Global Note 
or definitive Notes, in each case, and in any such case, by means of 
notations on the Schedule of Exchanges, Conversions, Redemptions, 
Repurchases, Cancellations and Transfers on the last page hereof.  
Notwithstanding any provision of this Restricted Global Note to the contrary,

Regulation S Global Note or definitive Notes, (ii) exchanges of interests in 
the Regulation S Global Note or definitive Notes for a part of this

Note or definitive Notes in return for a part of this Restricted Global Note 
and (vi) transfers of a part of this Restricted Global Note effected by 
delivery of interests in the Regulation S Global Note or definitive Notes may 
be effected without the surrendering of this Restricted Global Note, provided 
that appropriate notations on the Schedule of Exchanges, Conversions, 
Redemptions, Repurchases, Cancellations and Transfers are made by the 
Trustee, or the Custodian at the direction of the Trustee, to reflect the 
appropriate reduction or increase, as the case may be, in the aggregate 
principal amount of this Restricted Global Note resulting therefrom or as a 
consequence thereof.

         Reference is made to the further provisions of this Restricted 
Global Note set forth on the reverse hereof, including, without limitation, 
provisions giving the holder of this Restricted Global Note the right to 
convert this Restricted Global Note into Common Stock of the Company (or, 
under certain circumstances specified in the Indenture, into an amount of 
cash as set forth in the Indenture) on the terms and subject to the 
limitations referred to on the reveres hereof and as more fully specified in 
the Indenture.  Such further provisions shall for all purposes have the same 
effect as though fully set forth at this place.

         This Restricted Global Note shall not be valid or become obligatory 
for any purpose until the certificate of authentication hereon shall have 
been manually signed by the Trustee or a duly authorized authenticating agent 
under the Indenture.

                           PENN TREATY AMERICAN CORPORATION

                    6-1/4% Convertible Subordinated Notes Due 2003


         This Restricted Global Note is one of a duly authorized issue of 
Notes of the Company, designated as its 6-1/4% Convertible Subordinated Notes 
Due 2003 (herein called the "Notes"), limited to the aggregate principal 
amount of $65,000,000 (up to $74,750,000 aggregate principal amount assuming 
the full exercise of the over-allotment option granted to the initial 
purchasers of the Notes) all issued or to be issued under and pursuant to an 
Indenture dated as of November 26, 1996 (the "Indenture"), between the 
Company and First Union National Bank, as trustee (the "Trustee"), to which 
Indenture and all indentures supplemental thereto reference is hereby made 
for a complete description of the rights, limitations of rights, obligations, 
duties and immunities thereunder of the Trustee, the Company and the holders 
of the Notes.  Each Note is subject to, and qualified by, all such terms as 
set forth in the Indenture certain of which are summarized hereon and each 
holder of a Note is referred to the corresponding provisions of the Indenture 
for a complete statement of such terms.  To the extent that there is any 
inconsistency between the summary provisions set forth in the Notes and the 
Indenture, the provisions of the Indenture shall govern. Capitalized terms 
used but not defined in this Restricted Global Note shall have the meanings 
ascribed to them in the Indenture.

         In case an Event of Default, as defined in the Indenture, shall have 
occurred and be continuing, the principal of, premium, if any, and accrued 
interest on all Notes may be declared, and upon said declaration shall 
become, due and payable, in the manner, with the effect and subject to the 
conditions provided in the Indenture.

         The payment of principal of, premium, if any, and interest on the 
Notes will, to the extent set forth in the Indenture, be subordinated in 
right of payment to the prior payment in full of all Senior Indebtedness (as 
defined in the Indenture).  Upon any distribution to creditors of the Company 
in a liquidation or dissolution of the Company or in a bankruptcy, 
reorganization, insolvency, receivership or similar proceeding related to the 
Company or its property, in an assignment for the benefit of creditors or any 
marshalling of the Company's assets and liabilities, the holders of all 
Senior Indebtedness will first be entitled to receive payment in full of all 
amounts due or to become due thereon before the holders of the Notes will be 
entitled to receive any payment in respect of the principal of, 


                                      B-7

<PAGE>

premium, if any, or interest on the Notes (except that holders of Notes may 
receive securities that are subordinated at least to the same extent as the 
Notes to Senior Indebtedness and any securities issued in exchange for Senior 
Indebtedness).

         The Company also may not make any payment upon or in respect of the 
Notes (except in such subordinated securities) and may not acquire from the 
Trustee or the holder of any Note for cash or property (other than securities 
subordinated to at least the same extent as the Note to (i) Senior 
Indebtedness and (ii) any securities issued in exchange for Senior 
Indebtedness) until all Senior Indebtedness has been paid in full if (a) a 
default in the payment of the principal of, premium, if any, or interest on 
Senior Indebtedness occurs and is continuing beyond any applicable period of 
grace or (b) any other default occurs and is continuing with respect to 
Senior Indebtedness that permits holders of the Senior Indebtedness as to 
which such default relates to accelerate its maturity and the Trustee 
receives a notice of such default (a "Payment Blockage Notice") from the 
representative or representatives of holders of at least a majority in 
principal amount of Senior Indebtedness then outstanding.  Payments on the 
Notes may and shall be resumed (i) in the case of a Payment Default, upon the 
date on which such default is cured or waived, or (ii) in the case of a 
Nonpayment Default, 179 days after the date on which the applicable Payment 
Blockage Notice is received, unless the maturity of any Senior Indebtedness 
has been accelerated.  No new period of payment blockage may be commenced 
within 360 days after the receipt by the Trustee of any prior Payment 
Blockage Notice.  No default, other than a Nonpayment Default, that existed 
or was continuing on the date of delivery of any Payment Blockage Notice to 
the Trustee shall be, or be made, the basis for a subsequent Payment Blockage 
Notice unless such default shall have been cured or waived for a period of 
not less than 180 days.

         In the event that the Trustee (or paying agent if other than the 
Trustee) or any holder of the Notes receives any payment of principal or 
interest with respect to the Notes at a time when such payment is prohibited 
under the Indenture, such payment shall be held in trust for the benefit of, 
and immediately shall be paid over and delivered to, the holders of Senior 
Indebtedness or their representative as their respective interests may 
appear. After all Senior Indebtedness is paid in full and until the Notes are 
paid in full, the holders of the Notes shall be subrogated (equally and 
ratably with all other Indebtedness pari passu with the Notes) to the rights 
of holders of Senior Indebtedness to receive distributions applicable to 
Senior Indebtedness to the extent that distributions otherwise payable to the 
holders of the Notes have been applied to the payment of Senior Indebtedness.


                                      B-8

         The Indenture contains provisions permitting the Company and the 
Trustee, with the consent of the holders of not less than a majority in 
aggregate principal amount of the Notes at the time outstanding, evidenced as 
in the Indenture provided, to execute supplemental indentures adding any 
provisions to or changing in any manner or eliminating any of the provisions 
of the Indenture or of any supplemental indenture or modifying in any manner 
the rights of the holders of the Notes; provided that no such supplemental 
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate 
or extend the time of payment of interest thereon, or reduce the principal 
amount thereof or premium, if any, thereon, or reduce any amount payable on 
redemption thereof, alter the obligation of the Company to repurchase the 
Notes at the option of the holders upon the occurrence of a Change of 
Control, or impair or affect the right of any Noteholder to institute suit 
for the payment thereof, or make the principal thereof or interest or 
premium, if any, thereon payable in any coin or currency other than that 
provided in the Notes, modify the subordination provisions in a manner 
adverse to the holders of the Notes, or impair the right to convert the Notes 
into Common Stock subject to the terms set forth in the Indenture without the 
consent of the holder of each Note so affected or (ii) reduce the aforesaid 
percentage of Notes, the holders of which are required to consent to any such 
supplemental indenture, without the consent of the holders of all Notes then 
outstanding.  The Company and the Trustee may amend or supplement the 
Indenture without notice to or consent of any holder of Notes in certain 
events specified in the Indenture.  It is also provided in the Indenture 
that, prior to any declaration accelerating the maturity of the Notes, the 
holders of a majority in aggregate principal amount of the Notes at the time 
outstanding may on behalf of the holders of all of the Notes waive any past 
default or Event of Default under the Indenture and its consequences except a 
default in the payment of interest or any premium on or the principal of any 
of the Notes, a failure by the Company to convert any Notes into Common Stock 
of the Company, unless otherwise excused pursuant to the terms of the 
Indenture, or a default in respect of a covenant or provision of the 
Indenture that under Article X thereof cannot be modified or amended without 
the consent of the holders of all Notes then outstanding.  Any such consent 
or waiver by the holder of this Restricted Global Note (unless revoked as 
provided in the Indenture) shall be conclusive and binding upon such holder 
and upon all future holders and owners of this Restricted Global Note and any 
Notes that may be issued in exchange or substitution hereof, irrespective of 
whether or not any notation thereof is made upon this Restricted Global Note 
or such other Notes.

         No reference herein to the Indenture and no provision of this 
Restricted Global Note or of the Indenture shall alter or impair the 
obligation of the Company, which is absolute and 


                                      B-9
<PAGE>

unconditional, to pay the principal of and any premium and interest on this 
Restricted Global Note at the place, at the respective times, at the rate and 
in the coin or currency herein prescribed.

         Interest on the Notes shall be computed on the basis of a 360-day 
year composed of twelve 30-day months.

         The Notes are issuable in registered form without coupons in 
denominations of $1,000 principal amount and integral multiples thereof.  At 
the office or agency of the Company referred to on the face hereof, and in 
the manner and subject to the limitations provided in the Indenture, without 
payment of any service charge but with payment of a sum sufficient to cover 
any tax or other governmental charge that may be imposed in connection with 
any registration or exchange of Notes, Notes may be exchanged for a like 
aggregate principal amount of Notes of other authorized denominations.

         The Notes are not redeemable at the option of the Company prior to 
December 3, 1999.  At any time on or after that date, the Notes may be 
redeemed at the Company's option, upon notice as set forth in the Indenture, 
in whole at any time or in part from time to time, at the following prices 
(expressed in percentages of the principal amount), together with accrued 
interest to the date fixed for redemption if redeemed during the 12-month 
period beginning:

         Date                Redemption Price
         ----                ----------------
    December 3, 1999              103.13%
    December 1, 2000              102.08%
    December 1, 2001              101.04%

and 100% on or after December 1, 2002; provided that if the date fixed for 
redemption is a date on or after the record date and on or before the next 
following Interest Payment Date, then the interest payable on such date shall 
be paid to the holder of record on the next preceding May 15 or November 15, 
respectively.

         If a Change of Control (as defined in the Indenture) shall occur at 
any time, then each holder of Notes shall have the right to require that the 
Company repurchase such holder's Notes in whole or in part in integral 
multiples of $1,000, at a purchase price in cash in an amount equal to 101% 
of the principal amount of such Notes, plus accrued and unpaid interest, if 
any, to the repurchase date pursuant to an offer to be made by the Company 
and in accordance with the procedures set forth in the Indenture.


                                      B-10

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after 90 days following the latest date of
original issuance of the Notes and prior to the close of business on
November 28, 2003, subject to prior redemption or repurchase, or, as to all or
any portion hereof called for redemption, prior to the close of business one
business day before the date fixed for redemption (unless the Company shall
default in payment due upon redemption thereof), to convert the principal hereof
or any portion of such principal that is $1,000 or an integral multiple thereof,
into that number of fully paid and non-assessable shares of the Company's Common
Stock, as said shares shall be constituted at the date of conversion, obtained
by dividing the principal amount of this Restricted Global Note or portion
thereof to be converted by the conversion price of $28.44 per share or such
conversion price as adjusted from time to time as provided in the Indenture,
upon surrender of this Restricted Global Note, together with a conversion notice
as provided in the Indenture, to the Company at the office or agency of the
Company maintained for that purpose in the Borough of Manhattan, The City of New
York, or at the option of such holder, the Corporate Trust Office of the
Trustee, and, unless the shares issuable on conversion are to be issued in the
same name as this Restricted Global Note, duly endorsed by, or accompanied by
instruments of transfer in form satisfactory to the Company duly executed by,
the holder or by his duly authorized attorney.  

         Except as described in the Indenture, no adjustment will be made on
conversion of any Notes for interest accrued thereon or for dividends paid on
any Common Stock issued.  A Holder of Notes at the close of business on a record
date will be entitled to receive the interest payable on such Notes on the
corresponding interest payment date.  However, Notes surrendered for conversion
during the period from the close of business on a record date to the opening of
business on the next succeeding interest payment date must be accompanied by
funds equal to the interest payable on such succeeding interest payment date on
the principal amount so converted (unless such Note or portion thereof being
converted is called for redemption on a redemption date during the period from
the close of business on or after any record date to the close of business on
the business day following the corresponding interest payment date).  The
interest payment with respect to a Note called for redemption on a date between
the close of business on any record date for the payment of interest to the
close of business on the business day following the corresponding interest
payment date and surrendered for conversion during that period will be payable
on the corresponding interest payment date to the registered Holder at the close
of business on that record date (notwithstanding the conversion of such Note
before the corresponding interest payment date).  A Holder of Notes who elects
to convert during that 


                                      B-11

<PAGE>

period need not include funds equal to the interest paid. The Company is not 
required to issue fractional shares of Common Stock upon conversion of Notes 
and, in lieu thereof, will pay a cash adjustment based upon the closing price 
of the Common Stock on the last business day prior to the date of conversion.

         In the event a holder desires to convert all or any portion of its
Notes into shares of Common Stock and the Company does not have authorized a
sufficient number of shares of Common Stock for such conversion, in lieu of
delivering shares of Common Stock (or other securities into which the Notes are
then convertible) upon conversion of that portion of such holder's Notes for
which there is an insufficient number of shares of Common Stock (the "Cash
Equivalent Notes") pursuant to the provisions of the Indenture, the Company will
pay to the holder converting the Cash Equivalent Notes who properly exercises
the conversion privilege, as set forth in the Indenture, an amount in cash equal
to the Market Cash Conversion Price (as defined in the Indenture) of the shares
of Common Stock into which such Cash Equivalent Notes are then convertible.

         Upon due presentment for registration of transfer of this Restricted
Global Note at the office or agency of the Company in the Borough of Manhattan,
The City of New York, or at the option of the holder of this Restricted Global
Note, at the Corporate Trust Office of the Trustee, a new Note or Notes of
authorized denominations for an equal aggregate principal amount will be issued
to the transferee in exchange thereof, subject to the conditions and limitations
provided in the Indenture, without charge except for any tax or other
governmental charge imposed in connection therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,
any conversion agent and any Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Restricted Global Note (whether or
not this Restricted Global Note shall be overdue and notwithstanding any
notation of ownership or other writing hereon made by anyone other than the
Company or any Note registrar), for the purpose of receiving payment hereof, or
on account hereof, for the conversion hereof and for all other purposes, and
neither the Company nor the Trustee nor any other authenticating agent nor any
paying agent nor any other conversion agent nor any Note registrar shall be
affected by any notice to the contrary.  All payments made to or upon the order
of such registered holder shall, to the extent of the sum or sums paid, satisfy
and discharge liability for monies payable on this Restricted Global Note.

         No recourse for the payment of the principal of or any premium or
interest on this Restricted Global Note, or for any claim based hereon or
otherwise in respect hereof, and no

hereof) on December 1, 2003, at the office or agency of the Company 
maintained for that purpose in the Borough of Manhattan, The City of New 
York, or, at the option of the holder of this Regulation S Global Note, at 
the Corporate Trust Office of the Trustee, in such coin or currency of the 
United States of America as at the time of payment shall be legal tender for 
the payment of public and private debts, and to pay interest, semi-annually 
on June 1 and December 1 of each year (each an "Interest Payment Date"), 
commencing June 1, 1997, on said principal sum at said office or agency, in 
like coin or currency, at the rate per annum specified in the title of this 
Regulation S Global Note, from November 26, 1996 or the most recent Interest 
Payment Date, as the case may be, next preceding the date of this Regulation 
S Global Note to which interest has been paid or duly provided for, unless 
the date hereof is a date to which interest has been paid or duly provided 
for, in which case from the date of this Regulation S Global Note, or unless 
no interest has been paid or duly provided for on the Notes, in which case 
from November 26, 1996, until payment of said principal sum has been made or 
duly provided for. Any interest on any Note that is payable, but is not 
punctually paid or duly provided for on said June 1 or December 1 (herein 
called "Defaulted Interest") shall forthwith cease to be payable to the 
Noteholder on the relevant record date by virtue of his having been such 
Noteholder; and such Defaulted Interest shall be paid by the Company, at its 
election in each case, either (i) by notifying the Trustee of a special 
record date, the amount of interest to be paid on such special record date 
and the date of payment (not more than 25 days after receipt by the Trustee 
of such interest, unless the Trustee shall consent to an earlier date) and 
depositing with the Trustee an amount of money equal to the aggregate amount 
to be paid in respect of such Defaulted Interest on making arrangements 
satisfactory to the Trustee for such deposit or (ii) in any lawful manner not 
inconsistent with the requirements of any securities exchange on which the 
Notes may be listed and upon notice requested by such exchange, if, after 
notice to the Trustee, the Trustee deems such manner of payment to be 
practicable.  The interest so payable on any June 1 or December 1 will be 
paid to the person in whose name this Regulation S Global Note (or one or 
more Predecessor Notes) is registered at the close of business on the record 
date, which shall be the May 15 or November 15 (whether or not a Business 
Day) next preceding such June 1 or December 1, respectively; provided that 
any such interest not punctually paid or duly provided for shall be payable 
as provided in the Indenture.  Interest shall be paid by check mailed to the 
registered holder at the registered address of such person unless other 
arrangements are made in accordance with the provisions of the Indenture.

         The aggregate principal amount of this Regulation S Global Note
represented hereby may from time to time be reduced

Regulation S Global Note, provided that appropriate notations on the Schedule 
of Exchanges, Conversions, Redemptions, Repurchases, Cancellations and 
Transfers are made by the Trustee, or the Custodian at the direction of the 
Trustee, to reflect the appropriate reduction or increase, as the case may 
be, in the aggregate principal amount of this Regulation S Global Note 
resulting therefrom or as a consequence thereof.

Global Note set forth on the reverse hereof, including, without limitation,
provisions giving the holder of this Regulation S Global Note the right to

                         PENN TREATY AMERICAN CORPORATION

                  6-1/4% Convertible Subordinated Notes Due 2003


         This Regulation S Global Note is one of a duly authorized issue of
Notes of the Company, designated as its 6-1/4% Convertible Subordinated Notes
Due 2003 (herein called the "Notes"), limited to the aggregate principal amount
of $65,000,000 (up to $74,750,000 aggregate principal amount assuming the full
exercise of the over-allotment option granted to the initial purchasers of the
Notes) all issued or to be issued under and pursuant to an Indenture dated as of
November 26, 1996 (the "Indenture"), between the Company and First Union
National Bank, as trustee (the "Trustee"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a complete description of the
rights, limitations of rights, obligations, duties and immunities thereunder of
the Trustee, the Company and the holders of the Notes.  Each Note is subject to,
and qualified by, all such terms as set forth in the Indenture certain of which
are summarized hereon and each holder of a Note is referred to the corresponding
provisions of the Indenture for a complete statement of such terms.  To the
extent that there is any inconsistency between the summary provisions set forth
in the Notes and the Indenture, the provisions of the Indenture shall govern. 
Capitalized terms used but not defined in this Regulation S Global Note shall
have the meanings ascribed to them in the Indenture.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest on all Notes may be declared, and upon said declaration shall become,
due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

         The payment of principal of, premium, if any, and interest on the
Notes will, to the extent set forth in the Indenture, be subordinated in right
of payment to the prior payment in full of all Senior Indebtedness (as defined
in the Indenture).  Upon any distribution to creditors of the Company in a
liquidation or dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding related to the Company or its
property, in an assignment for the benefit of creditors or any marshalling of
the Company's assets and liabilities, the holders of all Senior Indebtedness
will first be entitled to receive payment in full of all amounts due or to
become due thereon before the holders of the Notes will be entitled to receive
any payment in respect of the principal of,


                                      C-8
<PAGE>

premium, if any, or interest on the Notes (except that holders of Notes may 
receive securities that are subordinated at least to the same extent as the 
Notes to Senior Indebtedness and any securities issued in exchange for Senior 
Indebtedness).

         The Company also may not make any payment upon or in respect of the
Notes (except in such subordinated securities) and may not acquire from the
Trustee or the holder of any Note for cash or property (other than securities
subordinated to at least the same extent as the Note to (i) Senior Indebtedness
and (ii) any securities issued in exchange for Senior Indebtedness) until all
Senior Indebtedness has been paid in full if (a) a default in the payment of the
principal of, premium, if any, or interest on Senior Indebtedness occurs and is
continuing beyond any applicable period of grace or (b) any other default occurs
and is continuing with respect to Senior Indebtedness that permits holders of
the Senior Indebtedness as to which such default relates to accelerate its
maturity and the Trustee receives a notice of such default (a "Payment Blockage
Notice") from the representative or representatives of holders of at least a
majority in principal amount of Senior Indebtedness then outstanding.  Payments
on the Notes may and shall be resumed (i) in the case of a Payment Default, upon
the date on which such default is cured or waived, or (ii) in the case of a
Nonpayment Default, 179 days after the date on which the applicable Payment
Blockage Notice is received, unless the maturity of any Senior Indebtedness has
been accelerated.  No new period of payment blockage may be commenced within 360
days after the receipt by the Trustee of any prior Payment Blockage Notice.  No
default, other than a Nonpayment Default, that existed or was continuing on the
date of delivery of any Payment Blockage Notice to the Trustee shall be, or be
made, the basis for a subsequent Payment Blockage Notice unless such default
shall have been cured or waived for a period of not less than 180 days.

         In the event that the Trustee (or paying agent if other than the
Trustee) or any holder of the Notes receives any payment of principal or
interest with respect to the Notes at a time when such payment is prohibited
under the Indenture, such payment shall be held in trust for the benefit of, and
immediately shall be paid over and delivered to, the holders of Senior
Indebtedness or their representative as their respective interests may appear. 
After all Senior Indebtedness is paid in full and until the Notes are paid in
full, the holders of the Notes shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Notes have
been applied to the payment of Senior Indebtedness.


                                      C-9
<PAGE>

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, evidenced as in
the Indenture provided, to execute supplemental indentures adding any provisions
to or changing in any manner or eliminating any of the provisions of the
Indenture or of any supplemental indenture or modifying in any manner the rights
of the holders of the Notes; provided that no such supplemental indenture shall
(i) extend the fixed maturity of any Note, or reduce the rate or extend the time
of payment of interest thereon, or reduce the principal amount thereof or
premium, if any, thereon, or reduce any amount payable on redemption thereof,
alter the obligation of the Company to repurchase the Notes at the option of the
holders upon the occurrence of a Change of Control, or impair or affect the
right of any Noteholder to institute suit for the payment thereof, or make the
principal thereof or interest or premium, if any, thereon payable in any coin or
currency other than that provided in the Notes, modify the subordination
provisions in a manner adverse to the holders of the Notes, or impair the right
to convert the Notes into Common Stock subject to the terms set forth in the
Indenture without the consent of the holder of each Note so affected or (ii)
reduce the aforesaid percentage of Notes, the holders of which are required to
consent to any such supplemental indenture, without the consent of the holders
of all Notes then outstanding.  The Company and the Trustee may amend or
supplement the Indenture without notice to or consent of any holder of Notes in
certain events specified in the Indenture.  It is also provided in the Indenture
that, prior to any declaration accelerating the maturity of the Notes, the
holders of a majority in aggregate principal amount of the Notes at the time
outstanding may on behalf of the holders of all of the Notes waive any past
default or Event of Default under the Indenture and its consequences except a
default in the payment of interest or any premium on or the principal of any of
the Notes, a failure by the Company to convert any Notes into Common Stock of
the Company, unless otherwise excused pursuant to the terms of the Indenture, or
a default in respect of a covenant or provision of the Indenture that under
Article X thereof cannot be modified or amended without the consent of the
holders of all Notes then outstanding.  Any such consent or waiver by the holder
of this Regulation S Global Note (unless revoked as provided in the Indenture)
shall be conclusive and binding upon such holder and upon all future holders and
owners of this Regulation S Global Note and any Notes that may be issued in
exchange or substitution hereof, irrespective of whether or not any notation
thereof is made upon this Regulation S Global Note or such other Notes.

         No reference herein to the Indenture and no provision of this
Regulation S Global Note or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and


                                     C-10
<PAGE>

unconditional, to pay the principal of and any premium and interest on this 
Regulation S Global Note at the place, at the respective times, at the rate and 
in the coin or currency herein prescribed.

         Interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months.

         The Notes are issuable in registered form without coupons in
denominations of $1,000 principal amount and integral multiples thereof.  At the
office or agency of the Company referred to on the face hereof, and in the
manner and subject to the limitations provided in the Indenture, without payment
of any service charge but with payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any
registration or exchange of Notes, Notes may be exchanged for a like aggregate
principal amount of Notes of other authorized denominations.

         The Notes are not redeemable at the option of the Company prior to
December 3, 1999.  At any time on or after that date, the Notes may be redeemed
at the Company's option, upon notice as set forth in the Indenture, in whole at
any time or in part from time to time, at the following prices (expressed in
percentages of the principal amount), together with accrued interest to the date
fixed for redemption if redeemed during the 12-month period beginning:

                    Date                   Redemption Price
                    ----                   ----------------
                December 3, 1999               103.13%
                December 1, 2000               102.08%
                December 1, 2001               101.04%

and 100% on or after December 1, 2002; provided that if the date fixed for
redemption is a date on or after the record date and on or before the next
following Interest Payment Date, then the interest payable on such date shall be
paid to the holder of record on the next preceding May 15 or November 15,
respectively.

         If a Change of Control (as defined in the Indenture) shall occur at
any time, then each holder of Notes shall have the right to require that the
Company repurchase such holder's Notes in whole or in part in integral multiples
of $1,000, at a purchase price in cash in an amount equal to 101% of the
principal amount of such Notes, plus accrued and unpaid interest, if any, to the
repurchase date pursuant to an offer to be made by the Company and in accordance
with the procedures set forth in the Indenture.


                                     C-11
<PAGE>

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after 90 days following the latest date of
original issuance of the Notes and prior to the close of business on November
28, 2003, subject to prior redemption or repurchase, or, as to all or any
portion hereof called for redemption, prior to the close of business one
business day before the date fixed for redemption (unless the Company shall
default in payment due upon redemption thereof), to convert the principal hereof
or any portion of such principal that is $1,000 or an integral multiple thereof,
into that number of fully paid and non-assessable shares of the Company's Common
Stock, as said shares shall be constituted at the date of conversion, obtained
by dividing the principal amount of this Regulation S Global Note or portion
thereof to be converted by the conversion price of $28.44 per share or such
conversion price as adjusted from time to time as provided in the Indenture,
upon surrender of this Regulation S Global Note, together with a conversion
notice as provided in the Indenture, to the Company at the office or agency of
the Company maintained for that purpose in the Borough of Manhattan, The City of
New York, or at the option of such holder, the Corporate Trust Office of the
Trustee, and, unless the shares issuable on conversion are to be issued in the
same name as this Regulation S Global Note, duly endorsed by, or accompanied by
instruments of transfer in form satisfactory to the Company duly executed by,
the holder or by his duly authorized attorney.

         Except as described in the Indenture, no adjustment will be made on
conversion of any Notes for interest accrued thereon or for dividends paid on
any Common Stock issued.  A Holder of Notes at the close of business on a record
date will be entitled to receive the interest payable on such Notes on the
corresponding interest payment date.  However, Notes surrendered for conversion
during the period from the close of business on a record date to the opening of
business on the next succeeding interest payment date must be accompanied by
funds equal to the interest payable on such succeeding interest payment date on
the principal amount so converted (unless such Note or portion thereof being
converted is called for redemption on a redemption date during the period from
the close of business on or after any record date to the close of business on
the business day following the corresponding interest payment date).  The
interest payment with respect to a Note called for redemption on a date between
the close of business on any record date for the payment of interest to the
close of business on the business day following the corresponding interest
payment date and surrendered for conversion during that period will be payable
on the corresponding interest payment date to the registered Holder at the close
of business on that record date (notwithstanding the conversion of such Note
before the corresponding interest payment date).  A Holder of Notes who elects
to convert during that


                                     C-12
<PAGE>

period need not include funds equal to the interest paid. The Company is not 
required to issue fractional shares of Common Stock upon conversion of Notes 
and, in lieu thereof, will pay a cash adjustment based upon the closing price 
of the Common Stock on the last business day prior to the date of conversion.

         In the event a holder desires to convert all or any portion of its
Notes into shares of Common Stock and the Company does not have authorized a
sufficient number of shares of Common Stock for such conversion, in lieu of
delivering shares of Common Stock (or other securities into which the Notes are
then convertible) upon conversion of that portion of such holder's Notes for
which there is an insufficient number of shares of Common Stock (the "Cash
Equivalent Notes") pursuant to the provisions of the Indenture, the Company will
pay to the holder converting the Cash Equivalent Notes who properly exercises
the conversion privilege, as set forth in the Indenture, an amount in cash equal
to the Market Cash Conversion Price (as defined in the Indenture) of the shares
of Common Stock into which such Cash Equivalent Notes are then convertible.

         Upon due presentment for registration of transfer of this Regulation S
Global Note at the office or agency of the Company in the Borough of Manhattan,
The City of New York, or at the option of the holder of this Regulation S Global
Note, at the Corporate Trust Office of the Trustee, a new Note or Notes of
authorized denominations for an equal aggregate principal amount will be issued
to the transferee in exchange thereof, subject to the conditions and limitations
provided in the Indenture, without charge except for any tax or other
governmental charge imposed in connection therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,
any conversion agent and any Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Regulation S Global Note (whether or
not this Regulation S Global Note shall be overdue and notwithstanding any
notation of ownership or other writing hereon made by anyone other than the
Company or any Note registrar), for the purpose of receiving payment hereof, or
on account hereof, for the conversion hereof and for all other purposes, and
neither the Company nor the Trustee nor any other authenticating agent nor any
paying agent nor any other conversion agent nor any Note registrar shall be
affected by any notice to the contrary.  All payments made to or upon the order
of such registered holder shall, to the extent of the sum or sums paid, satisfy
and discharge liability for monies payable on this Regulation S Global Note.

         No recourse for the payment of the principal of or any premium or
interest on this Regulation S Global Note, or for any claim based hereon or
otherwise in respect hereof, and no


                                     C-13
<PAGE>

recourse under or upon any obligation, covenant or agreement of the Company in 
the Indenture or any indenture supplemental thereto or in any Note, or because 
of the creation of any indebtedness represented thereby, shall be had against 
any incorporator, shareholder, officer or director, as such, past, present or 
future, of the Company or of any Successor Company, either directly or through 
the Company or any Successor Company, whether by virtue of any constitution, 
statute or rule of law or by the enforcement of any assessment or penalty or 
otherwise, all such liability being, by the acceptance hereof and as part of 
the consideration for the issue hereof, expressly waived and released.

         For value received __________________________________ hereby sell(s), 
assign(s) and transfer(s) unto _______________________ (please insert social 
security or other identifying number of assignee) the within Note, and hereby 
irrevocably constitutes and appoints ______________________________ attorney to 
transfer the said Note on the books of the Company, with full power of 
substitution in the premises.

         In connection with any transfer of the within Note occurring prior to
the third anniversary of the date of original issuance of such Note, the
undersigned confirms that such Note is being transferred:

   [ ] To Penn Treaty American Corporation or a subsidiary thereof; or

   [ ] Pursuant to and in compliance with Rule 144A under the Securities Act
       of 1933, as amended; or

   [ ] To an institutional accredited investor pursuant to and in compliance
       with the Securities Act of 1933, as amended; or

   [ ] Pursuant to and in compliance with Regulation S under the Securities
       Act of 1933, as amended; or

   [ ] Pursuant to and in compliance with Rule 144 under the Securities Act

         Unless one of the boxes above is checked, the Trustee will refuse to

registered holder thereof (or hereof); provided, however, that the Trustee may,
in its sole discretion, register the transfer of such Notes if it has received
such certifications, legal opinions and/or other information as the Company has
reasonably requested to confirm that such transfer is being made pursuant to an
exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act of 1933, as amended.

         In addition, if the transferee is an institutional accredited investor

partial transfer, a minimum amount of U.S.$1,000 and any integral multiple of

         In connection with such request, and in respect of such Notes, the
Transferor does hereby certify that such Notes are being transferred in
accordance with Rule 144A under the Securities Act of 1933, as amended (the
"Securities Act"), to a transferee that the Transferor reasonably believes is

transferee exercises sole investment discretion and the transferee and any such
account is a "qualified institutional buyer" within the meaning of Rule 144A, in
each case in a transaction meeting the requirements of Rule 144A and in
accordance with any applicable securities laws of any state of the United States
or any other jurisdiction.  The Transferor does

3.  REGISTRATION

         (a)  SHELF REGISTRATION.  The Company hereby agrees to:

              (i)  use its best efforts to file or cause to be filed a
         continuous registration statement pursuant to Rule 415 under the
         Securities Act (together with the Prospectus included therein, all
         amendments and supplements thereto (including post-effective
         amendments) and all exhibits and materials incorporated by reference
         therein, the "SHELF REGISTRATION STATEMENT") on or prior to the 90th
         day after the Closing Date (the "SHELF FILING DEADLINE"), which Shelf
         Registration Statement shall provide for resales of all Transfer
         Restricted Securities, PROVIDED that the Sellers thereof shall have
         provided in a timely manner the information required pursuant to
         Section 3(b) hereof; and

              (ii) use all reasonable efforts to cause the Shelf Registration
         Statement to be declared effective by the Commission as promptly as
         practicable after the Closing Date (the "EFFECTIVENESS TARGET DATE").

Subject to any notice by the Company in accordance with Section 4(b) hereof of
the existence of any fact or event of the kind described in Section 4(b)(iii)(D)
hereof, the Company shall use all reasonable efforts to keep the Shelf
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Sections 4(a) and (b) hereof to the extent
necessary to ensure that it is available for resales of Transfer Restricted
Securities by the Sellers entitled to the benefit of this Section 3(a) and to
ensure that the Shelf Registration Statement conforms to the requirements of
this Agreement, the Securities Act and the policies, rules and regulations of
the Commission as announced from time to time thereunder for a period of at
least three years following the Closing Date, PROVIDED that the Company shall
not be obligated to keep the Shelf Registration Statement effective, if it has
received an opinion from its counsel, Ballard Spahr Andrews & Ingersoll, or
other counsel designated by the Company and reasonably acceptable to the
Purchasers ("COMPANY

                                         5
<PAGE>

COUNSEL"), to the effect that the Transfer Restricted
Securities can be freely offered and sold without the continued effectiveness of
the Shelf Registration Statement.

         (b)  CERTIFIED SECURITIES; PROVISION BY SELLERS OF CERTAIN INFORMATION
IN CONNECTION WITH THE SHELF REGISTRATION STATEMENT.  No Seller of Transfer
Restricted Securities may include any of its Transfer Restricted Securities in
any Shelf Registration Statement pursuant to this Agreement unless such Seller
furnishes to the Company in writing, within 20 business days after receipt of a
request therefor, such information as the Company may reasonably request for use
in connection with the Shelf Registration Statement or any Prospectus or
preliminary Prospectus included therein.  After the first such request for
information by the Company, it shall be the sole responsibility of each Seller
to (i) notify the Company of any change of address or change of ownership of
Transfer Restricted Securities of such Seller and (ii) supply the Company with
such information that the Company reasonably needs in order to list such Seller
as a selling security holder in the Shelf Registration Statement or any
Prospectus or preliminary Prospectus included therein.  In connection with all
such requests for information from Sellers of Transfer Restricted Securities,
the Company shall use all reasonable efforts to notify such Sellers of the
requirements set forth in the preceding sentence.  Each Seller as to which any
Shelf Registration Statement is being effected agrees to furnish promptly to the
Company all information required to be disclosed in such Shelf Registration
Statement in order to make the information previously furnished to the Company
by such Seller for inclusion therein not materially misleading.

         (c)  REGISTERED EXCHANGE OFFER.  If, based upon a written opinion of
Company Counsel addressed and delivered to the Holders, the Company determines
that it is permissible under applicable law and Commission policy to Consummate
an Exchange Offer, the Company may at its election Consummate an Exchange Offer
in lieu of filing and maintaining the Shelf Registration Statement described
herein.  If the Company elects to Consummate an Exchange Offer in accordance
with the provisions hereof, the Company shall (i) cause to be filed with the
Commission no later than the Shelf Filing Deadline (or later if the Company has
filed and maintained a Shelf Registration Statement pursuant to this Agreement),
a Registration Statement (the "EXCHANGE OFFER REGISTRATION STATEMENT") under the
Securities Act relating to (A) a new issue of notes identical in all material
respects to the Notes except as to transfer restrictions (the "NEW NOTES") and
(B) the shares of Common Stock issuable upon conversion of such New Notes, (ii)
use all reasonable efforts to cause such Registration Statement to become
effective no later than the Effectiveness Target Date, (iii) in connection with
the foregoing, file (A) all pre-effective amendments to such Registration

                                         7
<PAGE>

Statement as may be necessary in order to cause such Registration Statement to
become effective, (B) if applicable, a post-effective amendment to such
Registration Statement pursuant to Rule 430A under the Securities Act and (C)
cause all necessary filings in connection with the registration and
qualification of the New Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer and
(iv) upon the effectiveness of the Registration Statement, commence the Exchange
Offer.  The Company shall cause the Exchange Offer to comply with all applicable
federal and state securities laws.  No securities other than the New Notes (and
the shares of Common Stock issuable upon conversion of such New Notes) shall be
included in the Exchange Offer Registration Statement.  The Company shall use
all reasonable efforts to cause the Exchange Offer to be Consummated on the
earliest practicable date after the Exchange Offer Registration Statement has
become effective, but in no event later than 30 Business Days after such
effectiveness.  The Exchange Offer shall be on the appropriate form permitting
registration of the New Notes to be offered in exchange for the Notes and to
permit resales of New Notes and shares of Common Stock received by Broker-
Dealers in the Exchange Offer by delivering the Prospectus contained in the
Exchange Offer Registration Statement.  The "Plan of Distribution" section in
the Prospectus contained in the Exchange Offer Registration Statement shall not
name any such Broker-Dealer or disclose the amount of Notes held by any such
Broker-Dealer except to the extent required by Commission policy.  The Company
shall use its best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented and amended to the extent necessary to
ensure that it is available for resales of New Notes acquired by Broker-Dealers
for their own accounts as a result of market-making activities or other trading
activities, and to ensure that it conforms with the requirements of this
Agreement, the Securities Act and the policies, rules and regulations of the
Commission as announced from time to time, for a period of one year from the
date on which the Exchange Offer Registration Statement is declared effective. 
The Company shall provide sufficient copies of the latest version of such
Prospectus to Broker-Dealers promptly upon request at any time during such 
one-year period in order to facilitate such resales.  Notwithstanding anything
herein to the contrary, despite the Consummation of an Exchange Offer, the
Company shall be required to file the Shelf Registration Statement in accordance
with Section 3(a) hereof if any Holder of Transfer Restricted Securities shall
notify the Company within 20 Business Days of the Consummation of the Exchange
Offer (x) that such Holder is prohibited by applicable law or Commission policy
from participating in the Exchange Offer or (y) that such Holder may not resell
the New Notes acquired by it in the Exchange Offer to the public without
delivering a prospectus and that the Prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such
Holder or

                                         7
<PAGE>

(z) that such Holder is a Broker-Dealer and holds Notes acquired
directly from the Company or one of its affiliates.

         such Registration Statement continuously effective and provide all
         requisite financial statements for the period specified in Section 3

         such Registration Statement or the Prospectus contained therein (A) to
         contain a material misstatement or omission or (B) not to be effective
         and usable for resales of Transfer Restricted Securities during the
         period required by this Agreement, the Company shall file promptly an
         appropriate amendment to such Registration Statement correcting any
         such misstatement or omission, and, in the case of either clause (A)
         or (B), except as set forth in Section 4(b)(xv) below, use all
         reasonable efforts to cause such amendment to be declared effective

         thereafter;
    
              (ii) subject to the provisions of Section 4(d) hereof, the

<PAGE>

         and post-effective amendments to such Registration Statement as may be
         necessary to keep such Registration Statement effective for the
         applicable period set forth in Section 3 hereof, or such shorter
         period as shall terminate when all Transfer Restricted Securities
         covered by such Registration Statement have been sold; subject to the
         provisions of Section 4(d) hereof, the Company shall cause the
         Prospectus to be supplemented by any required Prospectus supplement,
         and as so supplemented, cause the Prospectus to be filed pursuant to
         Rule 424 under the Securities Act and to comply fully with the
         applicable provisions of Rules 424 and 430A under the Securities Act
         in a timely manner; and comply with the provisions of the Securities
         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 set
         forth in such Registration Statement;

              (iii)     the Company shall use all reasonable efforts to advise
         the Sellers promptly and, if requested by such Persons, to confirm
         such advice in writing, (A) when the Prospectus or any Prospectus
         supplement or post-effective amendment to any Registration Statement
         in which the Sellers are listed as such has been filed, and, with
         respect to any 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 in which the Sellers are listed as
         such or for additional information relating thereto, (C) of the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement in which the Sellers are
         listed as such under the Securities 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 of
         the initiation of any proceeding for any of the preceding purposes or
         (D) of the existence of any fact or the happening of any event
         (including without limitation pending negotiations relating to, or the
         consummation of, a transaction or the occurrence of any event that
         would require additional disclosure of material, non-public
         information by the Company in the Registration Statement as to which
         the Company has a BONA FIDE business purpose for preserving
         confidentiality or that renders the Company unable to comply with
         Commission requirements) that makes untrue any statement of a material
         fact made in

                                         9
<PAGE>

         the Registration Statement, the Prospectus, any amendment or 
         supplement thereto in which the Sellers are listed as such or any
         document incorporated by reference therein, or that requires the
         making of any additions to or changes in the Registration Statement or
         the Prospectus in order to make the statements therein not misleading
         (it being understood, however, that the Company need merely advise the
         Sellers of the existence of such fact or event but shall not be
         obligated to describe the same, either generically or specifically). 
         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 Company shall use its best efforts to obtain the withdrawal
         or lifting of such order at the earliest possible time;

              (iv) the Company shall furnish to each Purchaser, and to each
         Seller who may have requested the same in writing, before filing with
         the Commission, copies of any Registration Statement or any Prospectus
         included therein and any amendments or supplements thereto (including
         all documents incorporated by reference prior to the effectiveness of
         such Registration Statement), which documents, other than documents
         incorporated by reference, shall be subject to the review by the
         Purchasers for a period of at least five Business Days, and the
         Company shall not file any such Registration Statement or Prospectus
         or any amendment or supplement to any such Registration Statement or
         Prospectus to which the Purchasers shall reasonably object within five
         Business Days after the receipt thereof;

              (v)  if practicable, promptly prior to the filing of any document
         that is to be incorporated by reference into a Registration Statement
         or Prospectus subsequent to the effectiveness thereof, and in any
         event no later than the date such document is filed with the

         and other customary due diligence matters, and include such

         such document prior to the filing thereof as the Purchasers reasonably
         may request;

              (vi) subject to Section 4(d) hereof, if so requested in writing
         by any Seller, the Company shall promptly incorporate in any
         Registration Statement or Prospectus, pursuant to a supplement or
         post-effective amendment if necessary, such information as such Seller
         may reasonably request in writing to have included therein, the
         purchase price being paid therefor and any other terms of the offering
         of the Transfer Restricted Securities or New Notes to be sold in such
         offering; and, subject to Section 4(d) hereof, make all required
         filings of any such Prospectus supplement or post-effective amendment
         as soon as practicable after the Company is notified of the matters to
         be incorporated in such Prospectus supplement or post-effective
         amendment;

              (vii)     upon the written request of a Seller, the Company shall
         furnish to such Seller 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);

              (viii)    the Company shall deliver to each Seller without
         charge, as many copies of the Prospectus (including each preliminary
         prospectus intended for public distribution) and any amendment or
         supplement thereto as such Seller reasonably may request; subject to
         any notice by the Company in accordance with this Section 4(b) of the
         existence of any fact or event of the kind described in Section
         4(b)(iii)(D) hereof, the Company hereby consents to the use of the
         Prospectus and any amendment or supplement thereto by each Seller
         named therein in connection with the offering and the sale of the
         Transfer Restricted Securities or New Notes covered by the Prospectus
         or any amendment or supplement thereto, PROVIDED that such use of the
         Prospectus, and such offering and sale, conforms to the Plan of
         Distribution set forth in the Prospectus and complies with all
         applicable laws;

              (ix) the Company shall cooperate with the Sellers to facilitate
         the timely preparation and delivery of certificates representing
         Transfer Restricted Securities to be sold and not bearing any
         restrictive legends


                                         11
<PAGE>

         and, subject to the terms of the Indenture, enable such certificates
         to be in such denominations and registered in such names as the 
         Sellers may request in writing at least two Business Days prior to
         any sale of Transfer Restricted Securities;

              (x)  as soon as reasonably practicable after the occurrence of
         any fact or event of the kind described in Section 4(b)(iii)(D) above,
         the Company shall 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 shall not contain an untrue
         statement of a material fact or omit to state any material fact
         necessary, in light of the circumstances in which it was made, to make
         the statements therein not misleading, PROVIDED that notwithstanding
         anything to the contrary herein, the Company shall not be required to
         prepare and file such a supplement or post-effective amendment or
         document if the fact no longer exists; and PROVIDED, FURTHER, that, in
         the event of a material business transaction (including without
         limitation pending negotiations relating to such a transaction) that,
         based upon the advice of the Company Counsel, would require disclosure
         by the Company in the Registration Statement of material, nonpublic
         information that the Company has a BONA FIDE business purpose for not
         disclosing, then for so long as such circumstances and such business
         purpose continue to exist, the Company shall not be required to
         prepare and file a supplement or post-effective amendment hereunder;

              (xi) the Company shall provide a CUSIP number for all Transfer
         Restricted Securities not later than the effective date of the
         Registration Statement and provide the Trustee under the Indenture
         with certificates for the Notes or New Notes, as the case may be, that
         are in a form eligible for deposit with The Depository Trust Company;

              (xii)     the Company shall otherwise use its best efforts to
         comply with all applicable rules and regulations of the Commission,
         and make generally available to its security holders, in a regular
         filing on Form 10-Q or Form 10-K, a consolidated earnings statement
         that covers a period of at least twelve consecutive calendar months
         commencing after the ef-

                                         12
<PAGE>

         fective date of the Registration Statement and satisfies the provisions
         of Section 11(a) of the Securities Act and Rule 158 thereunder;

              (xiii)    the Company shall cause the Indenture to be qualified
         under the TIA not later than the effective date of the first
         Registration Statement required to be filed by this Agreement, and, in
         connection therewith, cooperate with the Trustee and the Holders of
         Notes to effect such changes, if any, to the Indenture as may be
         required for such Indenture to be so qualified in accordance with the
         terms of the TIA, and execute, and use all reasonable efforts to cause
         the Trustee to execute, all documents that may be required to effect
         such changes and all other forms and documents required to be filed
         with the Commission to enable such Indenture to be so qualified in a
         timely manner;

              (xiv)     the Company shall cause the shares of Common Stock
         covered by the Registration Statement to be listed on such securities
         exchange or automated quotation system on which the Company's Common
         Stock is then listed; and

              (xv) the Company shall provide promptly to each Holder upon
         request any document filed with the Commission pursuant to the
         requirements of Section 13 and Section 15 of the Exchange Act.

    Each Seller, by its acquisition of a Transfer Restricted Security,
shall be deemed to have agreed that, upon receipt of any notice from the Company
of the existence of any fact or event of the kind described in Section
4(b)(iii)(D) hereof, such Seller shall:  (i) keep the fact of such notice
confidential and (ii) forthwith discontinue disposition of Transfer Restricted
Securities pursuant to the applicable Registration Statement until such Seller's
receipt of the copies of a supplemented or amended Prospectus as contemplated by
Section 4(b)(xv) hereof, or until it receives advice in writing (the "ADVICE")
from the Company that the use of the Prospectus may be resumed, and has received
copies of any additional or supplemental filings that are incorporated by
reference in the Prospectus.  If so directed by the Company, each Seller shall
deliver to the Company (at the expense of the Company) all copies, other than
permanent file copies then in such Seller's possession, of the Prospectus
covering such Transfer Restricted Securities that was current at the time of
receipt of such notice.  In the event the Company shall give any such notice,
the time period regarding the effectiveness of such Registration Statement set
forth in Section 3 hereof shall be extended by the number of days during the
period from and including the date of the



                                         13
<PAGE>

giving of such notice pursuant to Section 4(b)(iii)(D) hereof to and 
including the date when each Seller named in such Registration Statement 
shall have received the copies of the supplemented or amended prospectus 
contemplated by Section 4(b)(xv) hereof or shall have received the Advice, 
PROVIDED that the time period regarding the effectiveness of such 
Registration Statement set forth in Section 3 hereof shall not be extended, 
if the Company has received an opinion from Company Counsel to the effect 
that the Restricted Transfer Securities can be freely tradable without the 
continued effectiveness of the Shelf Registration Statement.

    (c)  In connection with the Exchange Offer, the Company shall comply with 
all of the provisions of Section 4(b) (other than those that are not 
applicable) and shall use its best efforts to effect such exchange to permit 
the sale of Transfer Restricted Securities being sold in accordance with the 
intended method or methods of distribution thereof.  In addition, prior to 
effectiveness of the Exchange Offer Registration Statement, the Company shall 
provide a supplemental letter to the Commission (i) stating that they are 
registering the Exchange Offer in reliance on the position of the Commission 
enunciated in EXXON CAPITAL HOLDINGS CORPORATION (available May 13, 1988), 
MORGAN STANLEY AND CO., INC. (available June 5, 1991) and, if applicable, any 
no-action letter obtained by the Company and (ii) including a representation 
that the Company has not entered into any arrangement or understanding with 
any Person to distribute the New Notes to be received in the Exchange Offer 
and that, to the best of the Company's information and belief, each Holder 
participating in the Exchange Offer is acquiring the New Notes in its 
ordinary course of business and has no arrangement or understanding with any 
Person to participate in the distribution of the New Notes received in the 
Exchange Offer. As a condition to its participation in the Exchange Offer 
pursuant to the terms of this Agreement, each Holder of Transfer Restricted 
Securities shall furnish, upon the request of the Company, prior to the 
Consummation thereof, a written representation to the Company (which may be 
contained in the letter of transmittal contemplated by the Exchange Offer 
Registration Statement) to the effect that (A) it is not an affiliate of the 
Company, (B) it is not engaged in and does not intend to engage in and has no 
arrangement or understanding with any person to participate in, a 
distribution of the New Notes to be issued in the Exchange Offer and (C) it 
is acquiring the New Notes in its ordinary course of business.  In addition, 
all such Holders of Transfer Restricted Securities shall otherwise cooperate 
in the Company's preparations for the Exchange Offer. Each Purchaser, for 
itself and on behalf of the Holders, hereby acknowledges and agrees, and each 
Holder by its purchase of Transfer Restricted Securities shall be deemed to 
have acknowledged and agreed, that any Broker-Dealer and any Holder using the 
Exchange Offer to participate in a distribution of the securities to be 
acquired in the Exchange Offer (1)


                                         14
<PAGE>

could not under Commission policy as in effect on the date of this Agreement 
rely on the position of the Commission enunciated in MORGAN STANLEY AND CO., 
INC. (available June 5, 1991) and EXXON CAPITAL HOLDINGS CORPORATION 
(available May 13, 1988), as interpreted in the Commission's letter to 
Shearman & Sterling dated July 2, 1993, and similar no-action letters and (2) 
must comply with the registration and prospectus delivery requirements of the 
Securities Act in connection with a secondary resale transaction and that 
such a secondary resale transaction should be covered by an effective 
registration statement containing the selling security holder information 
required by Item 507 or 508, as applicable, of Regulation S-K under the 
Securities Act if the resales are of New Notes obtained by such Holder in 
exchange for Notes acquired by such Holder directly from the Company.

    (d)  Notwithstanding anything to the contrary contained herein, the
Company shall be obligated to amend the Registration Statement or amend or
supplement the Prospectus no more often than quarterly if the sole reason for
such amendment or supplement is the furnishing of new or amended information
from one or more Sellers and until any such amendment or supplement is filed,
such Seller or Sellers, as the case may be, shall not sell any securities
pursuant to the then current Registration Statement and Prospectus.


5.  REGISTRATION EXPENSES

    The following expenses incident to the Company's performance of or
compliance with this Agreement shall be borne by the Company regardless of
whether a Registration Statement becomes effective, including, without
limitation:  (i) all registration and filing fees and expenses (including
filings made by any Purchaser or Seller with the NASD); (ii) the reasonable fees
and expenses of Weil, Gotshal & Manges LLP or such other single firm of counsel
as may be chosen by holders of a majority in principal amount of the Transfer
Restricted Securities included within the coverage of such Registration
Statement for the services of such firm in connection with the registration of
such Sellers' Transfer Restricted Securities under cover thereof; (iii) all
expenses of printing or copying (including printing of any certificates
evidencing the Notes and printing or copying of Prospectuses), messenger and
delivery services and telephone; (iv) all fees and disbursements of counsel for
the Company; (v) all application and filing fees in connection with listing of
the Common Stock on a national securities exchange or automated quotation system
pursuant to the provisions of Section 4(b)(xiv) hereof; and (vi) all fees and
disbursements of independent certified public accountants of the Company
(including the expenses of any special audit and comfort


                                         15
<PAGE>

letters required by or incident to such performance).  The Company shall, in 
any event, bear its own internal expenses (including, without limitation, all 
salaries and expenses of its officers and employees performing legal or 
accounting duties), the expenses of any annual audit and the fees and 
expenses of any Person, including special experts, retained by the Company.  
The Company shall not be responsible for any other expenses or costs, 
including, but not limited to, commissions, fees and discounts of brokers, 
dealers and agents.

6.  INDEMNIFICATION

    (a)  The Company agrees to indemnify and hold harmless (i) each Seller
and (ii) each person, if any, who controls (within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act) any Seller (any of the
persons referred to in this clause (ii) being hereinafter referred to as a
"controlling person") and (iii) the respective officers, directors, partners,
employees, representatives and agents of any Seller or any controlling person
(any person referred to in clause (i), (ii) or (iii) may hereinafter be referred
to as an "INDEMNIFIED PERSON"), to the fullest extent lawful, from and against
any and all losses, claims, damages, liabilities, judgments, costs and expenses
("LOSSES") (including, without limitation and as incurred, reimbursement of all
costs of investigating, preparing, pursuing or defending any claim or action, or
any investigation or proceeding by any governmental agency or body, commenced or
threatened, including the reasonable fees and expenses of counsel to any
Indemnified Person) directly or indirectly caused by, related to, based upon,
arising out of or in connection with any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement or
Prospectus (or any amendment or supplement thereto) or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, except (as to any Seller) insofar as
such Losses are caused by an untrue statement or omission or alleged untrue
statement or omission that is made in reliance upon and in conformity with
information relating to such Seller furnished in writing to the Company by such
Seller for use therein.  The Company shall notify the Sellers promptly of the
institution, threat or assertion of any claim, proceeding (including any
governmental investigation) or litigation in connection with the matters
addressed by this Agreement that involves the Company or any Indemnified Person.

    (b)  In case any action or proceeding (including, without limitation,
any governmental or regulatory investigation or proceeding) shall be brought or


                                         16
<PAGE>

asserted against any of the Indemnified Persons with respect to which indemnity
may be sought against the Company, such Indemnified Person shall promptly notify
the Company in writing (PROVIDED that the failure to give such notice shall not
relieve the Company of its obligations pursuant to this Agreement).  Any
Indemnified Person 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 such Indemnified Person, PROVIDED that the
fees and expenses of such counsel shall be at the expense of the Company if (i)
the Company has failed to assume the defense and employ counsel reasonably
satisfactory to the Sellers or (ii) the named parties to any such action
(including any impleaded parties) include such Indemnified Person and the
Company and such Indemnified Person shall have reasonably concluded that there
may be one or more legal defenses available to it that are different from or in
addition to those available to the Company; PROVIDED, FURTHER, that the Company
shall not in such event be responsible hereunder for the fees and expenses of
more than one firm of separate counsel, which firm shall be designated by the
Sellers and shall be subject to the Company's approval, not to be unreasonably
withheld, in connection with any one such action or separate but similar related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, in addition to any local counsel.  The Company shall not be
liable for any settlement of any such action or proceeding effected without its
prior written consent, which consent shall not be unreasonably withheld or
delayed, and the Company agrees to indemnify and hold harmless any Indemnified
Person from and against any Loss by reason of any settlement of any action
effected with its written consent.  The Company shall not, without the prior
written consent of each Indemnified Person, settle or compromise or consent to
the entry of a judgment in or otherwise seek to terminate any pending or
threatened action, claim, litigation or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not any
Indemnified Person is a party thereto), unless such settlement, compromise,
consent or termination includes a release of each Indemnified Person from all
liability arising out of such action, claim, litigation or proceeding.

    (c)  Each Seller, by including its Transfer Restricted Securities
within the coverage of a Registration Statement hereunder, shall be deemed to
have agreed, severally and not jointly, to indemnify and hold harmless the
Company, its directors, its officers, and any person controlling (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
the Company, and the respective officers, directors, partners, employees,
representatives and agents of each such person, to the same extent as the
foregoing indemnity from the Company to each of the Indemnified Persons, but
only with respect to claims and actions based on information relating to

                                         17
<PAGE>

such Seller furnished in writing by such Seller for use in any Registration 
Statement or Prospectus.  In case any action or proceeding shall be brought 
against the Company or any of its directors or officers or any such 
controlling person in respect of which indemnity may be sought against a 
Seller, such Seller shall have the rights and duties given the Company, and 
each of the Company or its directors or officers of such controlling person 
shall have the rights and duties given to each Indemnified Person by the 
proceeding paragraph.  In no event shall the liability of any Seller 
hereunder be greater in amount than the dollar amount of the proceeds 
received by such Seller upon the sale of the securities registered for the 
account of such Seller pursuant to provisions hereof.

    (d)  If the indemnification provided for in this Section 6 is
unavailable to a party entitled to indemnification in respect of any Losses
referred to herein, 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 (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Sellers on the other hand from their sale of Transfer Restricted
Securities or (ii) if such allocation is not permitted by applicable law, the
relative fault of the Company on the one hand and of the Indemnified Person on
the other in connection with the statements or omissions that resulted in such
Losses as well as any other relevant equitable considerations.  The relative
fault of the Company on the one hand and of the Indemnified Person on the other
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 Company or by
the Indemnified Person and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission. 
The indemnity and contribution obligations of each indemnifying party set forth
herein shall be in addition to any liability or obligation such indemnifying
party may otherwise have to any indemnified party, including under this
Agreement.

    The Company and each Purchaser, for itself and on behalf of the
Sellers, 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 Sellers
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.  The amount paid or payable by an
indemnified party as a result of the Losses referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such


                                         18
<PAGE>

indemnified party in connection with investigating or defending any such 
action or claim. Notwithstanding the provisions of this Section 6, none of 
the Sellers (and their related Indemnified Persons) shall be required to 
contribute, in the aggregate, any amount in excess of the amount by which the 
total proceeds received by such Seller with respect to the Notes exceeds the 
amount of any damages which such Seller 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 Securities Act) shall be entitled to 
contribution from any person who was not guilty of such fraudulent 
misrepresentation.  The Sellers' obligations to contribute pursuant to this 
Section 6(d) are several, in proportion to the respective principal amount of 
Notes held by each Seller, and not joint.

7.  RULE 144A

    The Company hereby agrees with each Holder, for so long as any
Transfer Restricted Securities remain outstanding, to make available to any
Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchase of such Transfer Restricted
Securities from such Holder or beneficial owner, any information required to be
supplied to a Holder by Rule 144A(d)(4) under the Securities Act in order to
permit offers and sales of such Transfer Restricted Securities pursuant to Rule
144A.


8.  MISCELLANEOUS

    (a)  REMEDIES.  Each party agrees that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by such party
of the provisions of this Agreement and hereby agrees to waive the defense in
any action for specific performance that a remedy at law would be adequate.

    (b)  NO INCONSISTENT AGREEMENTS.  The Company shall 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 or for the benefit of
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder are not inconsistent with the rights
granted to the holders of the Company's securities under any agreement in effect
on the date hereof.

Transfer Restricted Securities.
