-------------------------------------------------------------------------------
A.       INTRODUCTION
-------------------------------------------------------------------------------

This Purchase and Marketing Agreement (including attachments and the Terms and
Conditions of our service programs, if applicable) (the "Agreement") is between
Dell Marketing L.P. and Customer for (i) the purchase and sale, in the United
States only, of computer hardware and related products, including
software-licensing arrangements specified in this Agreement ("Products") and
services for the Products ("Services"), and (ii) the marketing of Products with
Customer's proprietary software to physicians in the United States in accordance
with the program described in Attachment C ("Physicians Program"). When Dell
refers to "Customer" in this Agreement, Dell means the Customer identified
above. The date on which Dell signs this Agreement is the effective date.

This Agreement runs for an initial one-year term, and it will thereafter renew
automatically for successive one-year terms. Either party may terminate this
Agreement sooner as provided for in the "Termination" section below.

Customer has the option to take advantage of various programs related to the
Customer's purchase of Products and Services from Dell. Customer may take
advantage of the various programs by issuing a purchase order to Dell. Once Dell
accepts the purchase order or does not reject it, the programs will become a
part of this Agreement, along with the "Terms and Conditions" (see "Available
Service Options" below) to which they relate.

-------------------------------------------------------------------------------
B.       HOW TO BUY PRODUCTS
-------------------------------------------------------------------------------

1.       OBTAINING QUOTES. Customer may request a quote for its purchases
         on-line from its Premier Pages site or directly from its sales
         representative. Dell's written quotes are binding on Dell for thirty
         days from the date issued or as otherwise agreed to in writing by the
         parties. If, however, there are shortages in materials, increases in
         the cost of manufacturing materials or components or other factors
         beyond the reasonable control of Dell, Dell may revise the quotes and
         increase the price(s) of the Products and Services.

2.       ORDERING AND DELIVERY OF PRODUCTS.

         (a)      Ordering Products. Customer may place an order for Products
                  and Services by telephone or in writing. Telephone orders must
                  be confirmed in writing; written orders and telephone order
                  confirmations may be sent by facsimile. Customer may also
                  place an order electronically by participating in the
                  Web-Based Order" program below. Orders will be binding on both
                  Dell and Customer, unless Dell has notified Customer prior to
                  its placement, in writing or orally, that Dell is not
                  accepting the order. Except for order specific terms such as
                  quantity and pricing, this Agreement will exclusively control
                  the terms and conditions of all orders Customer places. No
                  other terms and conditions such as those appearing on or
                  embedded in orders, confirmations, order acknowledgements or
                  other communications will be binding.

                                       1
<PAGE>   2

         (b)      Canceling or Changing Orders. Customer may change or cancel an
                  order until the time Dell begins to manufacture it.

         (c)      Shipping Dates, Title and Inspection. When Dell accepts an
                  order, Dell will provide Customer with an estimated ship
                  date(s) for all Products ordered. Title to the Products,
                  except software that is subject to licensing agreements (see
                  "Software" below), passes from Dell to Customer when Dell
                  ships the Products from its manufacturing location. If
                  Customer is not satisfied with the Products, it has the right
                  to return them under the then current "Total Satisfaction"
                  policies described below.

         (d)      Web-Based Order Program. Customer may place its orders on-line
                  through its Premier Pages web site under the Web-Based Order
                  program. If Customer elects to participate in this program,
                  Dell will issue user names and passwords (the "Purchase
                  Codes") to Customer's designated contact person for placing
                  orders electronically. The names and passwords, which Dell may
                  revise from time to time, will allow Customer to access its
                  Premier Pages web site and place online orders. Customer
                  agrees to keep the Purchasing Codes confidential and control
                  their use. Customer also agrees that Dell is not responsible
                  for, and hereby waives, any cause of action against Dell for
                  Customer's misuse of the Purchase Codes. Dell will deactivate
                  Customer's Purchase Codes, upon Customer's request. If
                  electronic orders are placed using the Purchase Codes,
                  Customer agrees that it will be responsible for full payment
                  of any Products or Services ordered electronically using this
                  Web-Based Order program. When Products or Services are ordered
                  through the use of Purchase Codes, all of the terms and
                  conditions of this Agreement apply, including but not limited
                  to those related to order confirmation and limitation of
                  liability.

3.       PRICING AND OTHER CHARGES.

         (a)      Pricing. This Agreement allows Customer to purchase Products
                  from Dell under two pricing programs at a discount off
                  standard list price or special pricing. Customer may meet
                  Dell's requirements for both programs, but Customer cannot
                  combine the programs for a single Product purchase. Pricing
                  related to the Physicians Program is described in Attachment
                  C.

         (b)      Discounts Off Standard List Price. Customer's discounts are
                  listed in Attachment A and are based on Customer's commitment
                  to purchase its exclusive internal hardware requirements from
                  Dell. With thirty days' notice, Dell may adjust Customer's
                  discounts if Customer's annual purchases do not meet that
                  commitment. If Customer orders Products under the new
                  discounts, those orders are Customer's acceptance of the new
                  discounts for purchases going forward.

         (c)      Special Pricing. During the term of this Agreement, Dell may
                  offer to Customer special pricing on a limited number of
                  configurations for a limited period of time. Special pricing
                  is available based on Customer's commitment to purchase a
                  certain quantity of the designated configurations. Add-ons or
                  modifications to the designated configurations will be priced
                  at the discount under the Discounts Off Standard List Price
                  provided for in Attachment A.

         (d)      How Dell Calculates Customer's Discounts. The discount rates
                  are a percentage reduction off of Dell's then-current standard
                  list prices for Products and are calculated before shipping
                  and handling charges are added. All standard list prices are
                  in U.S. dollars and will change from time-to-time. Customer's
                  discounts are not available for special Products promotions
                  and cannot be combined with other offers.

         (e)      Sales and Other Transaction Taxes. Except for taxes imposed on
                  the net income of Dell, Customer is responsible for and agrees
                  to pay all sales, value added and other transactional taxes
                  associated with the sale of Products and Services, unless
                  Customer provides to Dell a valid tax exemption certificate.

         (f)      Shipping and Handling Options and Pricing. Customer may select
                  from one of the two following shipping options: (1) Customer
                  may direct Dell to ship Products using Dell's designated
                  carrier or (2) Customer may designate another carrier. If
                  Customer directs Dell to ship by using Dell's designated
                  carrier, Dell will invoice Customer for shipping and handling
                  costs, and Dell will bear the risk of loss of or any damage to
                  the Products during shipping. If Customer directs Dell to ship
                  by using Customer's designated carrier, Dell will ship
                  Products via Customer's carrier, freight collect or freight
                  prepaid by Customer, and Customer will bear the risk of loss
                  of or any damage to the Products during shipping.

4.       INVOICING/PAYMENT.

         (a)      Invoice. Dell will send invoices to Customer for Products or
                  Services Customer purchases when or shortly after the Products
                  are shipped.

         (b)      Payment Terms. Customer's payment terms will be net thirty
                  days from the invoice date, subject to continuing credit
                  approval. For invoices not paid within thirty days of the
                  invoice date, a late penalty charge of one percent (1%) per
                  month (pro-rated daily) will be applied against undisputed
                  overdue amounts. If amounts are overdue, Dell may, without
                  waiving any other rights and remedies to which Dell may be
                  entitled, decide not to accept additional orders from
                  Customer, terminate this Agreement, refuse to ship ordered
                  Products and/or seek collection from Customer of all amounts
                  due, including reasonable legal fees and costs of collection.

5.       PRODUCT SPECIFICATION. Dell has not tested or certified its Products
         for use in high risk applications including medical life support,
         nuclear power, mass and air transportation control or any other
         potentially life critical uses. Customer understands and agrees that
         Dell makes no assurances that the Products are suitable for any
         high-risk uses. Dell continually upgrades and revises its Product lines
         to provide Dell customers with the new Product offerings. Dell may
         revise or discontinue Product offerings at any time without prior
         notice to its customers. This constant Product re-engineering may occur
         between the time Customer orders Products and when Dell ships those
         Products to Customer. As a result, Products shipped to Customer may
         display minor differences from the Products Customer ordered, but they
         will meet or exceed all material specifications of the Products
         Customer ordered. In addition, Dell will meet with Customer quarterly
         to discuss product roadmaps on the configurations for which Customer
         receives special pricing.

6.       AFFILIATES. Customer, its corporate parent(s), and their subsidiaries
         and affiliates that are majority-owned by them or are under the voting
         control of any of them (referred to as "Affiliate" or "Affiliates") may
         order Products under this Agreement. Customer agrees to make all
         Affiliates aware of the terms and conditions of this Agreement and that
         by submitting an order each respective Affiliate agrees to be bound by
         such terms and conditions. Dell, in its sole discretion, may
         discontinue selling Products under this Agreement to any Affiliate or
         may require additional payment conditions for any Affiliate. Each
         Affiliate must agree that it is buying for its own use, and not for
         resale.

-------------------------------------------------------------------------------
C.       AVAILABLE SERVICE OPTIONS
-------------------------------------------------------------------------------

Dell will provide general service and support, to Customer in the United States,
in accordance with the service and support policies and conditions available at
the time Customer purchases the Products.

2.       SOFTWARE. Dell distributes software with its hardware Products.
         Customer agrees and understands that Dell provides this software to
         Customer subject to the license agreement shipped with the software or
         in a separate agreement between Customer and the software licensor.
         Customer agrees that it is bound to and will abide by each such license
         agreement.

3.       WARRANTY DISCLAIMERS.

         DELL DOES NOT MAKE ANY EXPRESS OR IMPLIED WARRANTIES ON SERVICES OR
         PRODUCTS EXCEPT THOSE INCLUDED IN THE LIMITED WARRANTY STATEMENTS
         SHIPPED WITH PRODUCTS. THOSE LIMITED WARRANTY STATEMENTS ARE THE
         EXCLUSIVE CONTROLLING TERMS AND CONDITIONS OF THE LIMITED WARRANTIES
         FOR PRODUCTS, AND THERE ARE NO WARRANTIES FOR SERVICES. NOTHING IN THIS
         AGREEMENT OR ANY OTHER WRITTEN DOCUMENTATION OR ANY ORAL COMMUNICATIONS
         WITH CUSTOMER MAY ALTER THE TERMS AND CONDITIONS OF DELL'S LIMITED
         WARRANTY STATEMENTS OR DELL'S DISCLAIMER OF WARRANTY FOR SERVICES. DELL
         MAY, IN ITS SOLE DISCRETION, REVISE ITS LIMITED WARRANTIES FROM TIME TO
         TIME. NO CHANGE IN LIMITED WARRANTIES WILL AFFECT PRODUCTS ALREADY
         ORDERED BY CUSTOMER. IF CUSTOMER HAS NOT TIMELY PAID DELL FOR PRODUCTS
         OR SERVICES, DELL MAY, IN ITS SOLE DISCRETION, DISCONTINUE PROVIDING
         WARRANTY, SERVICE AND TECHNICAL SUPPORT FOR THE UNPAID PRODUCT OR
         SERVICES. DELL DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED,
         INCLUDING WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY
         AND FITNESS FOR A PARTICULAR PURPOSE. ANY WARRANTY PROVIDED ON SOFTWARE
         OR A DELLWARE PRODUCT IS PROVIDED BY THE PUBLISHER OR ORIGINAL
         MANUFACTURER AND MAY VARY FROM PRODUCT TO PRODUCT.

4.       DELL'S INDEMNITY FOR INFRINGEMENT OF THIRD PARTY INTELLECTUAL PROPERTY
         RIGHTS. Dell will indemnify Customer from any third party claim that a
         Dell-branded hardware Product infringes on another person's or
         company's patent, copyright, trade secret or other intellectual
         property right in the United States as specified in this Section. This
         indemnity does not cover and specifically excludes (a) intellectual
         property rights recognized in countries and jurisdictions other than
         the United States; and (b) claims relating to DellWare products,
         Products of other manufacturers distributed to Customer by Dell, and
         software. Dell has no obligation under this Section for any claim
         resulting or arising from Customer's unauthorized modification of a
         Product or from any combination, operation or use of the Products with
         systems other than those provided by Dell to the extent that the claim
         is caused by such modification, combination, operation or use of the
         Products. Dell's duty to indemnify under this Section is contingent
         upon Dell receiving prompt notice of a claim and Dell's right to solely
         control resolution of a claim. Customer's sole remedy for an
         indemnified claim under this Section is as follows: Dell will, at its
         expense and in its discretion either (a) resolve the claim in a way
         that permits Customer's continued ownership and use of the affected
         Product, (b) provide a comparable, non-infringing replacement at no
         cost to Customer, or (c) accept return of the Product freight collect
         and provide a reasonable depreciated refund. This Section is the
         exclusive statement of Dell's liability and responsibility for
         indemnifying Customer and nothing in this Agreement or elsewhere will
         obligate Dell to provide any greater indemnity to Customer.

6.       CONFIDENTIALITY AND NON-DISCLOSURE. If a separate, written
         nondisclosure agreement exists between Dell and Customer, such
         agreement will control and will apply according to its terms and
         conditions to all confidential information the parties exchange with
         each other. If no separate written nondisclosure agreement exists
         between Dell and Customer, the terms listed in Attachment D will apply

                  Agreement at any time for any reason (with or without cause)
                  by providing at least thirty days' prior written notice. If
                  either party breaches its obligations under this Agreement,
                  the other party may terminate this Agreement by providing ten

                  required for any assignments by Dell to its affiliates or
                  subsidiaries. With Dell's prior approval, for the purpose of
                  leasing Products, Customer may assign its rights to purchase
                  Products under this Agreement to a third party on the terms
                  listed in the Revocable Assignment for Third Party Leasing.

         (b)      Independence of Parties. No provision of this Agreement will
                  or shall be deemed to create a partnership, joint venture or
                  other combination between Dell and Customer.

         (c)      Entire Agreement. This Agreement (with attachments and Terms
                  and Conditions of our service programs that are material terms

                  between Dell and Customer with respect to its subject matter
                  and supersedes all prior verbal and written understandings,
                  communications or agreements between Dell and Customer. No

         (d)      Severability. If any provision of this Agreement is void or
                  unenforceable, the remainder of this Agreement will remain in
                  full force and will not be terminated.

         (e)      Events Beyond Either Party's Control. Neither party will be
                  liable for any delays resulting from circumstances or causes

                                  ATTACHMENT B

            TO THE PURCHASE AND MARKETING AGREEMENT (THE "AGREEMENT")

                      DELLPLUS FACTORY INTEGRATION SERVICES

Dell will provide factory integration services to Customer on the following
terms and conditions:

DELLPLUS SERVICES PURCHASED. This Attachment shall apply each time Customer
engages Dell to provide DellPlus Integration Services as more fully set forth,
in each case, on the Technical Specification document to be executed by Customer
for each DellPlus Configuration. DellPlus Integration services may include:

1.       Installation or integration of Customer's custom software image, which
may include industry standard and/or custom software (in each case, a "DellPlus
Configuration");

2.       Installation or integration of a pre-configured bundle of third party
hardware and/or software, in a Dell system ("Order Ready"), and

3.       Asset tagging hardware integration or other system integration
services.

TECHNICAL SPECIFICATIONS. Dell may, at Customer's request, deliver to Customer a
"DellPlus Configuration", defined as products which include either (i) DellPlus
Services or (ii) Order Ready bundles for a per-system fee to be determined
between the parties. Customer is responsible for determining Customer technical
specifications for each DellPlus Configuration and for ensuring that those
technical specifications are properly documented to Dell in a verified and
signed "Technical Specification" form. Dell is not responsible for the operation
or suitability of any DellPlus Configuration or for any revision or engineering
changes in any third party products included in a DellPlus Configuration.
Customer acknowledges that the DellPlus Configurations are of Customer's
choosing. Customer is responsible for ensuring that all technical specifications
are properly documented to Dell in a verified and signed "Technical
Specification" form. Dell shall be entitled to rely on the Technical
Specification form. Dell is not responsible for liability or damage arising from
the installation of a DellPlus Configuration performed in accordance with the
Technical Specification form and Customer's instructions. If Dell is of the
reasonable view that the proposed DellPlus Configuration is not technically
feasible, Dell reserves the right to refuse to proceed with the development of
the configuration at any time.

SOFTWARE INSTALLATION. Customer will provide to Dell any custom software to be
installed in a DellPlus Configuration and Customer authorizes Dell to copy,
install and modify, if necessary, all software to be installed in any DellPlus
Configuration or to be recorded in electronic media for subsequent
re-installation of backup. Customer grants to Dell a non-exclusive,
royalty-free, right and license to reproduce, install on Dell Hardware products
and distribute the custom software image in conjunction with sales of Dell
hardware products to Customer and end-users pursuant to the Physician Program
described in Attachment C to this Agreement. Customer represents and warrants
that it has the right to authorize and grant this license to Dell to make
copies, alterations, modifications or adjustments to any software included in a
custom software image for purposes of installation of the DellPlus
Configuration. Customer warrants to Dell that it has obtained the right to
authorize Dell to copy and install any software included in an Order Ready
Configuration. Customer further represents and warrants to Dell and the end
users in the Physicians Program that any of the Software that is proprietary to
Customer does not infringe on any U.S. patent, copyright, trademark, or trade
secret of any third party.

EXPORT. Customer acknowledges that the DellPlus Configurations licensed or sold
hereunder are subject to the export control laws and regulations of the USA or
those of other countries from which they were supplied and in which they are
used. Customer further represents and warrants the facts set forth on the
Technical Specification form or any technical specification sheet or other
document provided by Customer. Customer recognizes that Dell will rely on such
documents if Customer exports products for Customer. Customer is solely
responsible for obtaining any specific licenses relating to the export of
DellPlus Configurations if a license is needed. Dell's acceptance of any order
for a DellPlus Configuration is contingent upon the issuance of any applicable
export license required by the United States Government; Dell is not liable for
delays or failure to deliver a product resulting from Customer's failure to
obtain such license.

INDEMNIFICATION. Customer agrees to indemnify and hold Dell harmless from any
and all liability, damages, claims or proceedings arising out of (i) Customer's
failure to obtain the appropriate license or other intellectual property rights
to support the installation of the DellPlus Configuration or Order Ready
Configuration, including the right to make any copies or reproductions of the
software provided by Customer; or (ii) any inaccurate representations regarding
the existence of an export license or the eligibility for export of software
without a license or (iii) the software image provided to Dell by Customer.

                                  ATTACHMENT C

            TO THE PURCHASE AND MARKETING AGREEMENT (THE "AGREEMENT')

                           PHYSICIAN MARKETING PROGRAM

         Dell Marketing L.P. ("Dell") and InfoCure Corp. ("Company") agree that
the following terms and conditions will apply to Dell's participation as
exclusive computer hardware supplier in the Company's program ("Physicians
Program") to provide physicians and dentists with a computer hardware package
that includes Dell-branded hardware and the Company's proprietary software
image, which image will be provided to Dell from the Company and loaded pursuant
to the Dell's DellPlus Factory Integrated Services. The Program will offer
physicians in the United States ("Buyers") the opportunity to purchase (or to
have purchased on Buyer's behalf for Buyer to lease) computer hardware loaded
with Company's image ("Products") from Dell. In lieu of a direct purchase, Dell
Financial Services L.P., a separate legal entity from Dell, will provide a
leasing option to qualified Buyers, as determined exclusively by Dell Financial
Services L.P.

1.       SCOPE AND TERMINATION

1.1      This Agreement covers Buyers in the United States only. Dell and
Company shall use good faith efforts to promptly agree on mutual terms for
expansion of the Physician Program to the United Kingdom, Europe, and Australia.

1.2      Each party may terminate their participation in the Physicians Program
in the manner set forth in Section E7 of the Agreement. Upon termination,
neither party will have any claim for any incidental, indirect, special or
consequential damages against the other arising out of or in connection with the
investment it may have made in the relationship established under the Agreement.

2.       PRICES; STANDARD CONFIGURATIONS

2.1      Dell and Company will agree on standard configurations for inclusion in
the Program ("Program Configurations"), the price to be paid by Buyers (or by
Dell Financial Services L.P. on behalf of the Buyers) will be fixed for 90 days
for the Program Configurations. If Dell increases its prices generally to
customers due to shortages of manufacturing materials or components, or to other
factors beyond the control of Dell, then Dell may increase the prices of Program
Configurations with 30 days notice to Company. Any fixed price for the Program
Configurations will be less than the then published list price on www.dell.com.
On a quarterly basis or such other time requested by Company, Dell and Company
will meet to discuss the Products offered in the Program.

2.2      Dell and Company agree that Program Configurations are the Products
that will be promoted for the Program. At Company's request, Dell will consider
adding or changing the Program Configurations. If a Buyer contacts Dell through
the Program and requests pricing on Products other than the Program
Configurations, Dell may (but is not obligated) to offer discounted pricing to
such Buyer, and the discount, if any, for such other Products will depend on the
Product and quantity ordered.

2.3      The pricing offered herein and Dell's participation in the Program is
conditioned upon (i) Dell being the only provider of computer hardware,
software, and peripherals recommended by Company to the Buyers for the Intel
platform, and (ii) Company's exclusive purchase of Dell's hardware for its
future internal hardware needs.

2.4      The terms and conditions of each sale to the Buyers (or Dell Financial
Services L.P. to lease to Buyers) will be governed by Dell's standard terms and
conditions.

3.       PRODUCTS

3.1      Dell's policy is one of on-going product update and revision. Dell may
revise and discontinue Products and services at any time, without notice,
including the Program Configurations. The Products shipped pursuant to the
Program will meet or exceed the material specifications of Products ordered;
however, minor differences between Products as shipped and Products as described
in a specification sheet or catalog are possible. The parts and assemblies used
in building the Products sold under the Program are selected from new and
equivalent to new parts and assemblies in accordance with industry practices.

<PAGE>   10

3.2      The Products and services to be included in the Program shall be
mutually agreed by Dell and Company. Company acknowledges that a Buyer may
request additional product information and services and Dell, at its sole
discretion, may provide a Buyer with such additional information about, and
sell, such products and services that are not approved for the Program by
Company. Once Dell establishes an account for a Buyer, the Company will be
entitled to Marketing Fee as provided herein on any subsequent purchases by that
Buyer under that account number, including purchases of goods and services
outside of the Program Configurations. Dell reserves the right to limit the
Marketing Fee for such subsequent purchases outside of the Program
Configurations upon thirty (30) days written notice to Company.

4.       COMPANY CUSTOM SOFTWARE IMAGE

4.1      The Products sold pursuant to the Program will include the Company's
custom ASP, server-based, and/or licensed software (the "Image"), which Image is
proprietary to Company or Company's licensor. Dell will install the Image
pursuant to this Agreement (Attachment B). Dell will hold any Company
proprietary software in confidence for Company and not use it except as
necessary to perform Dell's obligations under this Agreement to load on Program
Configuration for Buyers.

4.2      Company will bill and collect any fees related to the use of the Image
by the Buyers. Except for the charge for installation of the Image, Dell has no
responsibility to collect any fees from the Buyers related to the Image included
on the Program Configuration. Neither Dell or any employee of Dell has authority
to determine or set Company pricing for the Image.

4.3      Company is responsible for providing technical support to the Buyers
for the Image. Company shall establish and maintain support services for Buyers
for its Image. Company is responsible for determining its technical
specifications for installing the Image on the Standard Configuration and for
ensuring that those technical specifications are properly documented to Dell in
a verified and signed "Technical Specification" form. Dell is not responsible
for the operation (except as provided in Attachment B of this Agreement) or
suitability of the Image on the Program Configuration. Company represents and
warrants that the Image is suitable for the intended purpose Company represents
to Buyers.

5.       COMPANY'S MARKETING EFFORTS AND ORDER PROCESS

5.1      At its expense, Company will use commercially reasonable efforts to
market the Program to Buyers. Dell hereby appoints Company to market Products in
accordance with the terms of this Agreement. Specifically, Company agrees that
it will only market the Products with Company's proprietary software. Company
may not use distributors, third party sales agents, or other remarketers to sell
the Products without Dell's prior written approval of each such distributor,
third party sales agent, or other remarketer.

5.2      Marketing/Order Process. Whenever commercially reasonable, Company
will endeavor to provide Dell with a list of prospective Buyers at least ten
(10) days prior to Company contacting the Buyer to market Dell hardware under
the Physician Program. Dell acknowledges it may not always receive advance
notice of the prospects and will still endeavor to provide prompt processing of
the Buyers. Dell will set up customer accounts for the Buyers. Company's sales
team will offer Buyer the Program Configurations. For Buyers that elect to buy,
Company's sales team will complete Dell's PO Bundle for approval by the Buyer
and then submit it to a dedicated Dell e-mail address for the Physician Program.
Dell will immediately enter the Order (adding the Dell customer number for the
Buyer and generating an Order number). Dell will forward the Order to Dell
Financial Services L.P. for its review and approval. If Dell Financial Services
L.P. elects to lease to the Buyer (at Dell Financial Services L.P.'s sole
discretion) and receives its required documentation, Dell Financial Services
L.P. will authorize Dell to release the Order for production. Company and Dell
acknowledge that the goal is to make the order process as simple as possible for
the Buyers. If Dell does not have advance notification to establish a customer
account or the Order is not completed or submitted properly, the ability to
expedite the Order process and track the Marketing Fee (defined below) will be
impaired. Dell and Company agree to work together to mutually agree and develop
the order process related to the Physician Program.

5.3      Except as provided herein, Dell may appoint other resellers or
remarketers to sell or may directly market Products (excluding the Image) to
anyone, including without limitation, Buyers. Dell will not market or sell or
distribute Company's image or proprietary software except through the Company
and the Physician Program and Dell will not use Buyer information provided by
Company for any purpose except for facilitating Company's Physician Program

<PAGE>   11

and order process. Dell may market (directly or through third party agents) the
Products and/or other products and services to Buyers at any price Dell chooses
without any obligation or liability to Company provided the marketing does not
use any information (including, without limitation, the Buyer information)
provided by Company. Dell reserves the right to change its distribution channels
for Products and add or terminate other distributors, third party sales agents
or other remarketers, including distributors, third party sales agents and other
remarketers who may compete with Company. This Agreement does not guarantee that
Company will make any sales of the Products.

5.4      Recordkeeping/Document Delivery. Company agrees to provide Dell with
fifteen (15) days prior written notice of any material change related to
Company's business, which materially alters Company's plans for marketing the
Products to its customers. Company will provide all its end users with warranty
statements, registration cards, Software license agreements and other materials
related to the Image.

5.5      Relationship of the Parties. Dell and Company are independent
contractors. Neither Party will make any warranties or representations or assume
any obligations on the other Party's behalf. Neither Party is nor will claim to
be a legal representative, partner, franchisee, agent or employee of the other
Party except as specifically stated in this Agreement. Each Party is responsible
for the direction and compensation, and is liable for the actions of, its
employees.

6.       PUBLIC RELEASE OF INFORMATION, TRADEMARKS AND ADVERTISING

6.1      Public Release of Information. Neither Party may publicly release any
information relating to this Agreement, including the existence of this
Agreement, without first receiving the prior written approval of the other
Party. Relative to Dell, such prior written approval must be obtained from
Dell's public relations department. No other department within Dell is
authorized to consent to public releases of information.

6.2      Advertising. Dell must approve all of Company's advertisements
concerning the Products or this Agreement. Dell may reject and disallow
Company's use of any advertising or publicity relative to the Products or this
Agreement that Dell finds, in Dell's sole discretion, to be inaccurate,
objectionable or misleading. Company, at Company's expense, will correct, change
or withdraw any such advertising or publicity rejected by Dell. The parties will
work together to streamline the advertising approval process with Dell providing
trademark usage guides and pre-approved advertising templates for Company's use.

6.3      Trademarks. Dell hereby grants Company the limited right to use Dell
trademarks and trade names for the limited purpose of marketing the Products to
Buyers. Company acquires no ownership rights in Dell trademarks or trade names
and the limited rights granted to Company under this Section end immediately
upon termination of this Agreement for any reason.

7.       DELL'S MARKETING MATERIALS

At its discretion, Dell may provide Company with marketing materials and
information regarding the Products offered through the Program for distribution
at Company expense by Company to Buyers. At its expense, Company will use
reasonable efforts to market the Program to Buyers. Unless otherwise agreed to
in writing, Dell will not prepare any special marketing materials related to the
Program and Company.

8.       MARKETING FEES

8.1      For orders that are placed through Company by Buyers in accordance with
this Agreement, Dell will pay a marketing fee ("Marketing Fee") in accordance
with this Agreement. Dell will pay on a quarterly basis, a Marketing Fee in the
amount of **** for Servers and **** for all other lines of business ("Marketing
Fee") based on the total dollar value of Qualifying Purchases (as defined
herein) during Dell's preceding fiscal quarter. Qualifying Purchases are all
purchases by Buyers (or on Buyers behalf by Dell Financial Services L.P.) made
via Company less shipping, handling, tax, returns and credits, and which
purchases are paid for during the prior fiscal quarter.

<PAGE>   12

8.2      Forty-five days after the end of each of Dell's fiscal quarters (April
30, July 31, October 31, January 31) during the term of this Agreement, Dell
will provide Company with a report, in a format to be defined by Dell, listing
Qualifying Purchases made during such prior fiscal quarter and will pay the
Marketing Fee on such amounts to Company at the address specified by Company.

8.3      Company agrees to notify each actual or prospective Buyer, where
necessary or required by law, of the potential payments that may be made to
Company by Dell prior to the time that such actual or prospective Buyer places
its order with Dell.

9.       LIMITATION OF LIABILITY

BOTH PARTIES EXPRESSLY AGREE THAT IN NO EVENT SHALL EITHER PARTY BE LIABLE OR
RESPONSIBLE TO THE OTHER PARTY FOR ANY INCIDENTAL, INDIRECT, SPECIAL OR
CONSEQUENTIAL DAMAGES WHATSOEVER, INCLUDING, BUT NOT LIMITED TO, LOST PROFITS
AND DAMAGES RESULTING FROM LOSS OF USE OR LOSS OF CORRUPTED DATA OR SOFTWARE,
EVEN IF SUCH PARTY HAS BEEN ADVISED, KNEW OF OR SHOULD HAVE KNOWN OF THE
POSSIBILITY THEREOF. THE PARTIES EXPRESSLY WAIVE ANY CLAIMS DESCRIBED IN THIS
SECTION. COMPANY FURTHER AGREES THAT IT SHALL INCLUDE IN ALL AGREEMENTS SELLING,
LEASING, OR TRANSFERRING OWNERSHIP OF THE PRODUCTS, A PROVISION SIMILAR TO THE
ABOVE DISCLAIMING AS TO DELL LIABILITY FOR INCIDENTAL, INDIRECT, SPECIAL, OR
CONSEQUENTIAL DAMAGES. DELL WILL NOT HAVE ANY LIABILITY FOR ANY DAMAGES ARISING
FROM THE USE OF THE PRODUCTS IN ANY HIGH-RISK ACTIVITY, INCLUDING, BUT NOT
LIMITED TO, THE OPERATION OF NUCLEAR FACILITIES, AIRCRAFT NAVIGATION OR
COMMUNICATION SYSTEMS, AIR TRAFFIC CONTROL, MEDICAL SYSTEMS, LIFE SUPPORT, OR
WEAPONS SYSTEMS.

10.      INDEMNIFICATION

10.1     Indemnity from Dell to Company.. Dell will indemnify Company from any
third party claim, demand, cause of action, debt or liability (including
attorneys' fees and expenses) that (a) Dell-branded hardware infringe,
misappropriate or otherwise violate any Intellectual Property rights of a third
party in the United States or that (b) Dell breached its agreement, its warranty
for Dell-Branded hardware or Dell provided services or otherwise arising out of
Dell's acts or omissions (an "Dell Indemnified Claim"). Dell will not indemnify
Company or bear any responsibility for any claim, demand, cause of action, debt
or liability based, in whole or part, upon Company's modification of the
Products or from any combination, operation or use of the Products with other
products or services. Dell's duty to indemnify under this Section is contingent
upon Dell receiving prompt notice of an Indemnified Claim and Dell's right to
solely control resolution of the Indemnified Claim. Company's sole remedy for a
Dell Indemnified Claim based on Infringement is as follows: Dell will, at its
expense and in its discretion, either (a) resolve the Indemnified Claim in a way
that permits continued ownership and use of the affected Product; (b) provide a
comparable non-infringing replacement Product at no cost to Company; or (c)
accept return of the Product freight collect and provide a reasonable
depreciated refund for the Product.

10.2     Indemnity from Company to Dell. Company will indemnify Dell from any
third party claim, demand, cause of action, debt or liability (including
attorneys' fees and expenses) that (a) Company's Image infringe, misappropriate
or otherwise violate any Intellectual Property rights of a third party in the
United States or that (b) Company breached its agreement, its warranty for the
Image or Company provided services or otherwise arising out of Company's acts or
omissions (an "Company Indemnified Claim"). Company will not indemnify Dell or
bear any responsibility for any claim, demand, cause of action, debt or
liability based, in whole or part, upon Dell's unauthorized modification or use
of Image. Company's duty to indemnify under this Section is contingent upon Dell
receiving prompt notice of a Company Indemnified Claim and Company's right to
solely control resolution of the Company Indemnified Claim. Company's sole
remedy for a Company Indemnified Claim based on Infringement is as follows:
Company will, at its expense and in its discretion, either (a) resolve the
Indemnified Claim in a way that permits continued ownership and use of the
affected Product; (b) provide a comparable non-infringing replacement Product at

                                  ATTACHMENT D

            TO THE PURCHASE AND MARKETING AGREEMENT (THE "AGREEMENT")

                            CONFIDENTIAL INFORMATION

For purposes of this Attachment D, "party" or "parties" shall mean Dell Computer
Corporation and Customer, including their respective subsidiaries and affiliates
who are providing information under this Agreement. The parties agree to
maintain confidential information as follows:

         1.       DEFINITION OF CONFIDENTIAL INFORMATION. The parties understand
                  and agree that confidential information is any and all current
                  and future Product and/or Services information, roadmap,
                  technical or financial information, customer names, addresses
                  and related data, contracts, practices, procedures and other
                  business information, including software reports, strategies,
                  plans, documents, drawings, machines, tools, models, patent
                  disclosures, samples, materials and requests for proposals
                  that may be disclosed between the parties, whether written,
                  oral, electronic or otherwise, however and wherever acquired
                  ("Confidential Information"). Confidential Information
                  excludes any information which would otherwise fall in the
                  definitions above, but which was (a) known to the recipient of
                  the information ("Recipient") before receipt from the
                  disclosing party; (b) publicly available through no fault of
                  Recipient; (c) rightly received by Recipient from a third
                  party without a duty of confidentiality; (d) disclosed by
                  disclosing party to a third party without a duty of
                  confidentiality on the third party; (e) independently
                  developed by Recipient without breach of this or any other
                  confidentiality agreement; or (f) disclosed by Recipient after
                  prior written approval from the disclosing party.

         2.       OBLIGATIONS OF CONFIDENTIALITY AND REMEDIES. Recipient agrees
                  to protect the disclosing party's Confidential Information
                  with the same degree of care, but no less than a reasonable
                  degree of care, as Recipient uses with respect to its own
                  Confidential Information. Neither party has any obligation to
                  exchange Confidential Information. Both parties acknowledge
                  and agree that the disclosure of the other party's
                  Confidential Information could cause irreparable harm.
                  Therefore, an injured party is entitled to applicable
                  equitable relief, including injunctions, in addition to other
                  remedies, for such wrongful disclosure of Confidential
                  Information. In addition, disclosure of Confidential
                  Information required by a government body or court of law is
                  not a violation of this Section if the Recipient gives prompt
                  notice of the required disclosure to the disclosing party.

         3.       TERM OF CONFIDENTIALITY OBLIGATIONS. Recipient's duty to
                  protect Confidential Information expires three (3) years from
                  the date of disclosure of the particular Confidential
                  Information, except for trade secrets, including without
                  limitation, Customer's Buyer lists and Customer-provided Buyer
                  information, which the Recipient shall have a duty to keep
                  confidential for so long as such information remains a trade
                  secret under applicable law.

         4.       COOPERATION REGARDING PUBLIC RELEASE OF INFORMATION. Both
                  parties agree to cooperate with each other in the release of
                  information, whether confidential or otherwise, relating to
                  the Agreement. Each party may mention the other party's name
                  in press releases or other public releases of information as
                  long as they have first obtained the other party's permission,
                  in writing, prior to the release of the information.

         5.       NO WARRANTIES ON CONFIDENTIAL INFORMATION. Neither party
                  warrants or guarantees the accuracy of any Confidential
                  Information transferred between the parties.Exhibit 4.1

SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

     In any case where  several  matters  are  required to be  certified  by, or
covered by an opinion of, any specified  Person,  it is not  necessary  that all
such  matters  be  certified  by, or covered by the  opinion  of,  only one such
Person,  or that they be so certified or covered by only one  document,  but one
such Person may certify or give an opinion  with respect to some matters and one
or more other such Persons as to other matters,  and any such Person may certify
or give an opinion as to such matters in one or several documents.

form one instrument.

SECTION 104. ACTS OF HOLDERS; RECORD DATES.

     Any request, demand,  authorization,  direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given,  made or taken
by Holders  may be  embodied  in and  evidenced  by one or more  instruments  of
substantially  similar  tenor  signed by such Holders in person or by agent duly
appointed in writing;  and, except as herein otherwise expressly provided,  such
action shall become  effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required,  to the Company. Such
instrument  or  instruments  (and the  action  embodied  therein  and  evidenced
thereby) are herein  sometimes  referred to as the "Act" of the Holders  signing
such instrument or instruments.  Proof of execution of any such instrument or of
a writing  appointing any such agent shall be sufficient for any purpose of this
Indenture  and (subject to Section 601)  conclusive  in favor of the Trustee and
the Company, if made in the manner provided in this Section.

     The fact and date of the execution by any Person of any such  instrument or
writing may be proved by the  affidavit  of a witness of such  execution or by a
certificate  of a notary  public  or  other  officer  authorized  by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a  signer  acting  in a  capacity  other  than  his  individual  capacity,  such
certificate  or  affidavit  shall  also  constitute   sufficient  proof  of  his
authority. The fact and date of the execution of any such instrument or writing,
or the  authority of the Person  executing  the same,  may also be proved in any
other manner which the Trustee deems sufficient.

     The ownership of Securities shall be proved by the Security Register.

     Any request, demand,  authorization,  direction, notice, consent, waiver or
other Act of the Holder of any Security  shall bind every  future  Holder of the
same Security and the Holder of every Security  issued upon the  registration of
transfer  thereof  or in  exchange  therefor  or in lieu  thereof  in respect of
anything  done,  omitted or suffered to be done by the Trustee or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Security.

     The Company may set any day as a record date for the purpose of determining
the Holders of Outstanding  Securities of any series  entitled to give,  make or
take any request, demand,  authorization,  direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given,  made or taken
by Holders of Securities of such series, PROVIDED that the Company may not set a
record  date for,  and the  provisions  of this  paragraph  shall not apply with
respect  to,  the  giving or  making  of any  notice,  declaration,  request  or
direction referred to in the next paragraph.  If any record date is set pursuant
to this paragraph,  the Holders of Outstanding Securities of the relevant series
on such  record  date,  and no  other  Holders,  shall be  entitled  to take the
relevant  action,  whether or not such Holders  remain Holders after such record
date;  PROVIDED that no such action shall be effective hereunder unless taken on
or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding  Securities of such series on such record date. Nothing in
this  paragraph  shall be  construed  to prevent the Company  from setting a new
record  date for any  action  for which a record  date has  previously  been set
pursuant  to this  paragraph  (whereupon  the record date  previously  set shall
automatically  and with no action by any Person be cancelled  and of no effect),
and nothing in this  paragraph  shall be  construed  to render  ineffective  any
action  taken by  Holders  of the  requisite  principal  amount  of  Outstanding
Securities  of the  relevant  series on the date such action is taken.  Promptly
after any record date is set pursuant to this paragraph, the Company, at its own
expense,  shall cause notice of such record date, the proposed action by Holders
and the applicable  Expiration Date to be given to the Trustee in writing and to
each  Holder of  Securities  of the  relevant  series in the manner set forth in
Section 106.

         The  Trustee  may set any  day as a  record  date  for the  purpose  of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default,  (ii) any  declaration  of
acceleration  referred  to in  Section  502,  (iii)  any  request  to  institute
proceedings  referred to in Section 507(2) or (iv) any direction  referred to in
Section 512, in each case with  respect to  Securities  of such  series.  If any
record  date is set  pursuant  to this  paragraph,  the  Holders of  Outstanding
Securities of such series on such record date,  and no other  Holders,  shall be
entitled to join in such notice, declaration,  request or direction,  whether or
not such Holders  remain  Holders after such record date;  PROVIDED that no such
action shall be effective  hereunder  unless taken on or prior to the applicable
Expiration  Date by Holders of the  requisite  principal  amount of  Outstanding
Securities of such series on such record date.  Nothing in this paragraph  shall
be  construed  to prevent  the  Trustee  from  setting a new record date for any
action  for  which a  record  date has  previously  been  set  pursuant  to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be  cancelled  and of no  effect),  and  nothing in this
paragraph  shall be construed to render  ineffective any action taken by Holders
of the  requisite  principal  amount of  Outstanding  Securities of the relevant
series on the date such action is taken.  Promptly  after any record date is set
pursuant to this paragraph,  the Trustee, at the Company's expense,  shall cause

                                      -8-
<PAGE>
notice of such record date,  the proposed  action by Holders and the  applicable
Expiration  Date to be given to the  Company  in writing  and to each  Holder of
Securities of the relevant series in the manner set forth in Section 106.

     With  respect to any record date set  pursuant to this  Section,  the party
hereto which sets such record  dates may  designate  any day as the  "Expiration
Date" and from time to time may change  the  Expiration  Date to any  earlier or
later day;  PROVIDED that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing,  and
to each Holder of Securities  of the relevant  series in the manner set forth in
Section 106, on or prior to the existing  Expiration Date. If an Expiration Date
is not designated  with respect to any record date set pursuant to this Section,
the party  hereto  which set such record date shall be deemed to have  initially
designated  the 180th day after such  record  date as the  Expiration  Date with
respect thereto,  subject to its right to change the Expiration Date as provided
in this paragraph.  Notwithstanding  the foregoing,  no Expiration Date shall be
later than the 180th day after the applicable record date.

     Without  limiting the foregoing,  a Holder  entitled  hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal  amount of such Security or by one or more duly
appointed  agents  each of which may do so  pursuant  to such  appointment  with
regard to all or any part of such principal amount.

SECTION 105. NOTICES, ETC., TO TRUSTEE AND COMPANY.

     Any request, demand,  authorization,  direction, notice, consent, waiver or
Act of Holders or other  document  provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

                                      -9-
<PAGE>
          (1) the  Trustee by any Holder or by the Company  shall be  sufficient
     for every purpose hereunder if made,  given,  furnished or filed in writing
     to or with the Trustee at its Corporate Trust Office, Attention:  Corporate
     Trust Trustee Administration, or

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

SECTION 106. NOTICE TO HOLDERS; WAIVER.

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

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

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

     If any provision hereof limits,  qualifies or conflicts with a provision of
the Trust  Indenture  Act which is  required  under such Act to be a part of and
govern this Indenture,  the latter provision shall control.  If any provision of
this  Indenture  modifies or excludes any  provision of the Trust  Indenture Act
which may be so modified or excluded,  the latter  provision  shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

SECTION 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

     The Article and Section  headings  herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

     In case any  provision  in this  Indenture  or in the  Securities  shall be
invalid, illegal or unenforceable,  the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 111. BENEFITS OF INDENTURE.

     Nothing in this Indenture or in the Securities,  express or implied,  shall
give to any Person, other than the parties hereto and their successors hereunder
and the Holders,  any benefit or any legal or equitable  right,  remedy or claim
under this Indenture.

     This  Indenture  and the  Securities  shall be governed by and construed in
accordance with the law of the State of New York, without regard to conflicts of
laws principles thereof.

SECTION 113. LEGAL HOLIDAYS.

     In any case where any  Interest  Payment  Date,  Redemption  Date or Stated
Maturity of any  Security  shall not be a Business  Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
(other than a provision  of any  Security  which  specifically  states that such
provision shall apply in lieu of this Section)) payment of interest or principal
(and  premium,  if any) need not be made at such  Place of Payment on such date,

with the same  force  and  effect  as if made on the  Interest  Payment  Date or

SECTION 302. DENOMINATIONS.

     The  Securities of each series shall be issuable  only in fully  registered
form  without  coupons and only in such  denominations  as shall be specified as

with respect to the  Securities  of any series,  the  Securities  of such series
shall be issuable in denominations of $1,000 and any integral multiple thereof.

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The  Securities  shall be executed on behalf of the Company by its Chairman

Presidents,  under  its  corporate  seal  reproduced  thereon  attested  by  its
Secretary or one of its  Assistant  Secretaries  or Associate  Secretaries.  The
signature of any of these officers on the Securities may be manual or facsimile.

     Securities  bearing the manual or facsimile  signatures of individuals  who
were at any time the proper  officers  of the  Company  shall bind the  Company,
notwithstanding  that such  individuals  or any of them have ceased to hold such
offices prior to the  authentication  and delivery of such Securities or did not
hold such offices at the date of such Securities.

                                      -20-
<PAGE>
     At any time and from time to time after the  execution and delivery of this
Indenture,  the  Company may deliver  Securities  of any series  executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication  and delivery of such  Securities,  and the Trustee in accordance
with the Company Order shall  authenticate and deliver such  Securities.  If the
form or terms of the  Securities  of the  series  have  been  established  by or
pursuant to one or more Board  Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this  Indenture  in relation  to such  Securities,  the  Trustee  shall be
entitled to receive,  and (subject to Section  601) shall be fully  protected in
relying upon, an Opinion of Counsel stating,

          (1) if the form of such Securities has been established by or pursuant
     to Board  Resolution  as permitted by Section 201,  that such form has been
     established in conformity with the provisions of this Indenture;

          (2) if the  terms  of such  Securities  have  been  established  by or
     pursuant to Board  Resolution  as permitted by Section 301, that such terms
     have been  established in conformity with the provisions of this Indenture;
     and

          (3) that such  Securities,  when  authenticated  and  delivered by the
     Trustee  and  issued  by the  Company  in the  manner  and  subject  to any
     conditions specified in such Opinion of Counsel,  will constitute valid and
     legally binding  obligations of the Company  enforceable in accordance with
     their  terms,  subject  to  bankruptcy,  insolvency,  fraudulent  transfer,
     reorganization,  moratorium  and  similar  laws  of  general  applicability
     relating  to  or  affecting   creditors'   rights  and  to  general  equity
     principles.

If such  form or terms  have  been so  established,  the  Trustee  shall  not be
required  to  authenticate  such  Securities  if the  issue  of such  Securities
pursuant to this  Indenture  will  affect the  Trustee's  own rights,  duties or
immunities  under the  Securities  and this  Indenture  or otherwise in a manner
which is not reasonably acceptable to the Trustee.

     Notwithstanding  the  provisions  of  Section  301  and  of  the  preceding
paragraph,  if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers'  Certificate  otherwise
required  pursuant to Section  301 or the  Company  Order and Opinion of Counsel
otherwise  required  pursuant  to such  preceding  paragraph  at or prior to the
authentication  of each Security of such series if such  documents are delivered
at or prior to the  authentication  upon original issuance of the first Security
of such series to be issued.

     Each Security shall be dated the date of its authentication.

     No Security  shall be entitled to any benefit  under this  Indenture  or be
valid or  obligatory  for any purpose  unless there  appears on such  Security a
certificate  of  authentication  substantially  in the form  provided for herein
executed  by the  Trustee  by manual  signature  and such  certificate  upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has  been  duly  authenticated  and  delivered  hereunder.  Notwithstanding  the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the  Company,  and the Company  shall  deliver such
Security to the Trustee for  cancellation  as provided in Section  309,  for all

                                      -21-
<PAGE>
purposes of this  Indenture  such  Security  shall be deemed  never to have been
authenticated  and  delivered  hereunder  and  shall  never be  entitled  to the
benefits of this Indenture.

SECTION 304. TEMPORARY SECURITIES.

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

     If temporary  Securities  of any series are issued,  the Company will cause
definitive  Securities of that series to be prepared without unreasonable delay.
After the  preparation  of definitive  Securities of such series,  the temporary
Securities of such series shall be  exchangeable  for  definitive  Securities of
such series upon  surrender of the  temporary  Securities  of such series at the
office or agency of the Company in a Place of Payment for that  series,  without
charge  to the  Holder.  Upon  surrender  for  cancellation  of any  one or more
temporary  Securities  of any series,  the Company shall execute and the Trustee
shall  authenticate  and deliver in  exchange  therefor  one or more  definitive
Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount. Until so exchanged,  the temporary Securities of
any series  shall in all  respects be entitled to the same  benefits  under this
Indenture as definitive Securities of such series and tenor.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

     The Company  shall cause to be kept at the  Corporate  Trust  Office of the
Trustee a  register  (the  register  maintained  in such  office or in any other
office or agency of the  Company in a Place of Payment  being  herein  sometimes
referred to as the  "Security  Register") in which,  subject to such  reasonable
regulations as it may prescribe,  the Company shall provide for the registration
of Securities  and of transfers of Securities.  The Trustee is hereby  appointed
"Security Registrar" for the purpose of registering  Securities and transfers of
Securities as herein provided.

     Upon surrender for  registration of transfer of any Security of a series at
the office or agency of the Company in a Place of Payment for that  series,  the
Company shall execute,  and the Trustee shall  authenticate and deliver,  in the
name of the designated transferee or transferees,  one or more new Securities of
the same series, of any authorized denominations and of like tenor and aggregate
principal amount.

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

                                      -22-
<PAGE>
     All  Securities  issued  upon any  registration  of transfer or exchange of
Securities  shall be the valid  obligations of the Company,  evidencing the same
debt, and entitled to the same benefits under this Indenture,  as the Securities
surrendered upon such registration of transfer or exchange.

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

     No  service  charge  shall  be made for any  registration  of  transfer  or
exchange of Securities,  but the Company may require payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
with any  registration  of  transfer  or  exchange  of  Securities,  other  than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

     If the Securities of any series (or of any series and specified  tenor) are
to be redeemed,  the Company  shall not be required  (A) to issue,  register the
transfer of or  exchange  any  Securities  of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of  redemption of any
such  Securities  selected for redemption and ending at the close of business on
the day of such  mailing,  or (B) to register  the  transfer of or exchange  any
Security so selected for  redemption in whole or in part,  except the unredeemed
portion of any Security being redeemed in part.

     The  provisions  of Clauses (1), (2), (3) and (4) below shall apply only to
Global Securities:

          (1) Each Global Security  authenticated  under this Indenture shall be
     registered  in the  name  of the  Depositary  designated  for  such  Global
     Security or a nominee thereof and delivered to such Depositary or a nominee
     thereof  or  custodian  therefor,  and  each  such  Global  Security  shall
     constitute a single Security for all purposes of this Indenture.

          (2) Notwithstanding  any other provision in this Indenture,  no Global
     Security may be exchanged  in whole or in part for  Securities  registered,
     and no transfer of a Global Security in whole or in part may be registered,
     in the name of any  Person  other  than  the  Depositary  for  such  Global
     Security or a nominee  thereof unless (A) such  Depositary (i) has notified
     the Company that it is unwilling  or unable to continue as  Depositary  for
     such Global Security or (ii) has ceased to be a clearing agency  registered
     under the Exchange  Act, (B) there shall have occurred and be continuing an
     Event of Default  with  respect to such Global  Security or (C) there shall
     exist  such  circumstances,  if  any,  in  addition  to or in  lieu  of the
     foregoing  as have been  specified  for this  purpose  as  contemplated  by
     Section 301.

          (3) Subject to Clause (2) above, any exchange of a Global Security for
     other Securities may be made in whole or in part, and all Securities issued

                                      -23-
<PAGE>
     in  exchange  for a  Global  Security  or  any  portion  thereof  shall  be
     registered in such names as the Depositary  for such Global  Security shall
     direct.

          (4) Every Security  authenticated  and delivered upon  registration of
     transfer  of, or in  exchange  for or in lieu of, a Global  Security or any
     portion thereof, whether pursuant to this Section, Section 304, 306, 906 or
     1107 or otherwise, shall be authenticated and delivered in the form of, and
     shall be, a Global Security, unless such Security is registered in the name
     of a Person other than the Depositary for such Global Security or a nominee
     thereof.

SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

     If any mutilated Security is surrendered to the Trustee,  the Company shall
execute and the Trustee shall  authenticate  and deliver in exchange  therefor a
new  Security  of the same  series  and of like tenor and  principal  amount and
bearing a number not contemporaneously outstanding.

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

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

     Upon the issuance of any new Security  under this Section,  the Company may
require the payment of a sum  sufficient to cover any tax or other  governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

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

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

                                      -24-

SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

     Except as otherwise provided as contemplated by Section 301 with respect to
any series of  Securities,  interest on any  Security  which is payable,  and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to  the  Person  in  whose  name  that  Security  (or  one or  more  Predecessor
Securities)  is registered  at the close of business on the Regular  Record Date
for such interest.

     Any  interest on any  Security of any series  which is payable,  but is not
punctually  paid or duly  provided  for, on any  Interest  Payment  Date (herein
called  "Defaulted  Interest") shall forthwith cease to be payable to the Holder
on the relevant  Regular  Record Date by virtue of having been such Holder,  and
such  Defaulted  Interest  may be paid by the  Company,  at its election in each
case, as provided in Clause (1) or (2) below:

          (1) The Company may elect to make payment of any Defaulted Interest to
     the  Persons  in whose  names  the  Securities  of such  series  (or  their
     respective Predecessor  Securities) 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 proposed to be paid
     on each Security of such series and the date of the proposed  payment,  and
     at the same time the Company  shall  deposit  with the Trustee an amount of
     money equal to the aggregate  amount proposed to be paid in respect of such
     Defaulted  Interest or shall make arrangements  satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited  to be held in trust for the benefit of the  Persons  entitled to
     such Defaulted  Interest as in this Clause provided.  Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted  Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the  Trustee of the  notice of the  proposed  payment.  The  Trustee  shall
     promptly  notify the Company of such  Special  Record Date and, in the name
     and at the  expense of the  Company,  shall  cause  notice of the  proposed
     payment of such Defaulted  Interest and the Special Record Date therefor to
     be given to each  Holder of  Securities  of such  series in the  manner set
     forth in Section 106,  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

     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 on the
     Securities of any series in any other lawful manner not  inconsistent  with
     the requirements of any securities exchange on which such Securities may be
     listed, and upon such notice as may be required by such exchange, if, after
     notice given by the Company to the Trustee of the proposed payment pursuant
     to this Clause,  such manner of payment shall be deemed  practicable by the

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

SECTION 308. PERSONS DEEMED OWNERS.

     Prior to due presentment of a Security for  registration  of transfer,  the
Company,  the  Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such  Security is  registered as the owner of such Security
for the  purpose  of  receiving  payment of  principal  of and any  premium  and
(subject  to  Section  307) any  interest  on such  Security  and for all  other
purposes  whatsoever,  whether or not such Security be overdue,  and neither the
Company,  the  Trustee  nor any agent of the  Company  or the  Trustee  shall be
affected by notice to the contrary.

SECTION 309. CANCELLATION.

     All  Securities  surrendered  for  payment,  redemption,   registration  of
transfer or exchange or for credit  against any sinking fund payment  shall,  if
surrendered  to any Person other than the  Trustee,  be delivered to the Trustee
and shall be promptly  cancelled  by it. The Company may at any time  deliver to
the  Trustee  for  cancellation  any  Securities  previously  authenticated  and
delivered   hereunder  which  the  Company  may  have  acquired  in  any  manner
whatsoever,  and may deliver to the Trustee (or to any other Person for delivery
to  the  Trustee)  for  cancellation  any  Securities  previously  authenticated
hereunder  which the  Company  has not issued and sold,  and all  Securities  so
delivered  shall be promptly  cancelled by the Trustee.  No Securities  shall be
authenticated in lieu of or in exchange for any Securities cancelled as provided
in this Section, except as expressly permitted by this Indenture.  All cancelled
Securities  held by the  Trustee  shall be  disposed of as directed by a Company
Order; provided, however, that the Trustee shall not be required to destroy such
cancelled Securities.

SECTION 310. COMPUTATION OF INTEREST.

     Except as otherwise specified as contemplated by Section 301 for Securities
of any series,  interest on the  Securities  of each series shall be computed on
the basis of a 360-day year of twelve 30-day months.

SECTION 311. CUSIP NUMBERS.

     The Company in issuing  the  Securities  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  Securities  or as  contained  in any  notice  of a
redemption  and that  reliance  may be placed  only on the other  identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

discharge of this Indenture, when

     delivered to the Trustee for cancellation; or

          (B) all such Securities not  theretofore  delivered to the Trustee for
     cancellation

               (i) have become due and payable, or

          redemption  by the  Trustee in the name,  and at the  expense,  of the
          Company,

and the  Company,  in the case of (i),  (ii) or (iii)  above,  has  deposited or
caused to be deposited  with the Trustee as trust funds in trust for the purpose
money in an amount  sufficient to pay and discharge the entire  indebtedness  on
such Securities not theretofore  delivered to the Trustee for cancellation,  for
principal  and any premium and interest to the date of such deposit (in the case
of  Securities  which have become due and payable) or to the Stated  Maturity or
Redemption Date, as the case may be;

          (2) the Company  has paid or caused to be paid all other sums  payable

     Notwithstanding  the  satisfaction  and  discharge of this  Indenture,  the
obligations of the Company to the Trustee under Section 607, the  obligations of
the Company to any  Authenticating  Agent under  Section 614 and, if money shall
have been deposited with the Trustee  pursuant to subclause (B) of Clause (1) of
this  Section,  the  obligations  of the Trustee  under Section 402 and the last
paragraph of Section 1003 shall survive.

deposited  with the  Trustee  pursuant to Section 401 shall be held in trust and
applied by it, in  accordance  with the  provisions of the  Securities  and this
Indenture,  to  the  payment,  either  directly  or  through  any  Paying  Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

     or the making by it of an assignment  for the benefit of creditors,  or the
     admission by it in writing of its  inability to pay its debts  generally as
     they  become  due,  or the  taking of  corporate  action by the  Company in
     furtherance of any such action; or

          (7) any other Event of Default  provided with respect to Securities of
     that series.

SECTION 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event of Default (other than an Event of Default specified in Section
501(5)  or  501(6))  with  respect  to  Securities  of any  series  at the  time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal  amount of the Outstanding  Securities
of that series may declare the  principal  amount of all the  Securities of that
series  (or,  if any  Securities  of that  series are  Original  Issue  Discount
Securities,  such portion of the principal  amount of such  Securities as may be
specified by the terms thereof) to be due and payable  immediately,  by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such  declaration  such  principal  amount (or  specified  amount)  shall become
immediately due and payable.  If an Event of Default specified in Section 501(5)
or 501(6)  with  respect to  Securities  of any  series at the time  Outstanding
occurs,  the principal  amount of all the  Securities of that series (or, if any
Securities of that series are Original Issue Discount  Securities,  such portion
of the  principal  amount of such  Securities  as may be  specified by the terms

                                      -29-
<PAGE>
thereof) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

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

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

               (A) all overdue interest on all Securities of that series,

               (B) the principal of (and premium,  if any, on) any Securities of
          that series which have become due otherwise  than by such  declaration
          of  acceleration  and  any  interest  thereon  at the  rate  or  rates
          prescribed therefor in such Securities,

               (C) to the  extent  that  payment  of such  interest  is  lawful,
          interest  upon  overdue  interest  at the  rate  or  rates  prescribed
          therefor in such Securities, and

               (D) all sums paid or advanced by the  Trustee  hereunder  and the
          reasonable compensation,  expenses,  disbursements and advances of the
          Trustee, its agents and counsel;

     and

          (2) all Events of Default with respect to  Securities  of that series,
     other than the  non-payment  of the  principal of Securities of that series
     which have become due solely by such declaration of acceleration, have been
     cured or waived as provided in Section 513.

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

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

     The Company covenants that if

          (1)  default is made in the payment of any  interest  on any  Security
     when such interest becomes due and payable and such default continues for a
     period of 30 days, or

          (2) default is made in the payment of the principal of (or premium, if
     any, on) any Security at the Maturity thereof,

                                      -30-
<PAGE>
the Company will, upon demand of the Trustee,  pay to it, for the benefit of the
Holders  of such  Securities,  the whole  amount  then due and  payable  on such
Securities  for  principal  and any premium and interest and, to the extent that
payment of such interest shall be legally  enforceable,  interest on any overdue
principal  and  premium  and on any  overdue  interest,  at the  rate  or  rates
prescribed therefor in such Securities,  and, in addition thereto,  such further
amount as shall be  sufficient  to cover the costs and  expenses of  collection,
including the reasonable compensation,  expenses,  disbursements and advances of
the Trustee, its agents and counsel.

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

SECTION 504. TRUSTEE MAY FILE PROOFS OF CLAIM.

     In case of any  judicial  proceeding  relative to the Company (or any other
obligor upon the Securities),  its property or its creditors,  the Trustee shall
be entitled and empowered,  by intervention in such proceeding or otherwise,  to
take any and all actions  authorized  under the Trust  Indenture Act in order to
have claims of the Holders and the Trustee  allowed in any such  proceeding.  In
particular, the Trustee shall be authorized to collect and receive any moneys or
other  property  payable or deliverable on any such claims and to distribute the
same; and any custodian,  receiver, assignee, trustee, liquidator,  sequestrator
or other similar official in any such judicial  proceeding is hereby  authorized
by each Holder to make such  payments to the Trustee  and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation,  expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

     No provision of this Indenture  shall be deemed to authorize the Trustee to
authorize  or  consent to or accept or adopt on behalf of any Holder any plan of
reorganization,  arrangement, adjustment or composition affecting the Securities
or the  rights of any  Holder  thereof or to  authorize  the  Trustee to vote in
respect of the claim of any Holder in any such  proceeding;  PROVIDED,  HOWEVER,
that the  Trustee  may,  on behalf of the  Holders,  vote for the  election of a
trustee in  bankruptcy  or similar  official and be a member of a creditors'  or
other similar committee.

SECTION 505. TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

     All rights of action and claims under this  Indenture or the Securities may
be prosecuted  and enforced by the Trustee  without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such  proceeding  instituted  by the Trustee shall be brought 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  Securities  in respect  of which  such  judgment  has been
recovered.

                                      -31-
<PAGE>
SECTION 506. APPLICATION OF MONEY COLLECTED.

     Any money  collected  by the  Trustee  pursuant  to this  Article  shall be
applied in the following  order,  at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities and the notation thereon of 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 607;

     SECOND:  To the payment of the amounts then due and unpaid for principal of
and any premium and  interest on the  Securities  in respect of which or for the
benefit of which such money has been collected,  ratably,  without preference or
priority  of any  kind,  according  to the  amounts  due  and  payable  on  such
Securities for principal and any premium and interest, respectively; and

     THIRD:  To the payment of the balance,  if any, to the Company or any other
Person or Persons legally entitled thereto.

SECTION 507. LIMITATION ON SUITS.

     No Holder of any  Security of any series  shall have any right to institute
any proceeding,  judicial or otherwise,  with respect to this Indenture,  or for
the  appointment  of a receiver or trustee,  or for any other remedy  hereunder,
unless

          (1) such Holder has previously  given written notice to the Trustee of
     a  continuing  Event of  Default  with  respect to the  Securities  of that
     series;

          (2) the  Holders  of not less  than  25% in  principal  amount  of the
     Outstanding  Securities  of that series shall have made written  request to
     the Trustee to institute proceedings in respect of such Event of Default in
     its own name as Trustee hereunder;

          (3) such  Holder or Holders  have  offered to the  Trustee  reasonable
     indemnity  against the costs,  expenses and  liabilities  to be incurred in
     compliance with such request;

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

          (5) no direction inconsistent with such written request has been given
     to the Trustee  during  such 60-day  period by the Holders of a majority in
     principal amount of the Outstanding Securities of that series;

it being  understood and intended that no one or more of such Holders shall have
any right in any manner  whatever by virtue of, or by availing of, any provision
of this  Indenture to affect,  disturb or  prejudice  the rights of any other of
such Holders,  or to obtain or to seek to obtain priority or preference over any

                                      -32-
<PAGE>
other of such  Holders or to enforce any right under this  Indenture,  except in
the manner herein  provided and for the equal and ratable benefit of all of such
Holders.

SECTION 508. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
             PREMIUM AND INTEREST.

     Notwithstanding  any other provision in this  Indenture,  the Holder of any
Security shall have the right, which is absolute and  unconditional,  to receive
payment of the  principal  of and any  premium  and  (subject  to  Section  307)
interest on such Security on the respective Stated Maturities  expressed in such
Security  (or,  in the  case  of  redemption,  on the  Redemption  Date)  and to
institute suit for the  enforcement  of any such payment,  and such rights shall
not be impaired without the consent of such Holder.

SECTION 509. RESTORATION OF RIGHTS AND REMEDIES.

     If the Trustee or any Holder has  instituted  any proceeding to enforce any
right or remedy under this Indenture and such  proceeding has been  discontinued
or abandoned for any reason, or has been determined  adversely to the Trustee or
to such Holder,  then and in every such case,  subject to any  determination  in
such  proceeding,  the  Company,  the Trustee and the Holders  shall be restored
severally and  respectively to their former  positions  hereunder and thereafter
all rights and remedies of the Trustee and the Holders shall  continue as though
no such proceeding had been instituted.

SECTION 510. RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise  provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
306, no right or remedy herein  conferred  upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy,  and every
right and remedy shall,  to the extent  permitted by law, be  cumulative  and in
addition to every other right and remedy  given  hereunder  or now or  hereafter
existing at law or in equity or  otherwise.  The  assertion or employment of any
right or remedy  hereunder,  or  otherwise,  shall not  prevent  the  concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 511. DELAY OR OMISSION NOT WAIVER.

     No delay or omission of the Trustee or of any Holder of any  Securities  to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or  constitute  a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised  from time to time,  and as often
as may be deemed  expedient,  by the Trustee or by the Holders,  as the case may
be.

SECTION 512. CONTROL BY HOLDERS.

     The Holders of a majority in principal amount of the Outstanding Securities
of any  series  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,  with respect to the Securities of
such series, provided that

                                      -33-
<PAGE>
          (1) such  direction  shall not be in conflict  with any rule of law or
     with this Indenture,

          (2) the Trustee may take any other action deemed proper by the Trustee
     which is not inconsistent with such direction, and

          (3) subject to the  provisions  of Section 601, the Trustee shall have
     the right to decline to follow any such  direction  if the  Trustee in good
     faith shall, by a Responsible Officer or Officers of the Trustee, determine
     that the  proceedings  so  directed  would  involve the Trustee in personal
     liability.

SECTION 513. WAIVER OF PAST DEFAULTS.

     The  Holders  of not  less  than a  majority  in  principal  amount  of the
Outstanding  Securities  of any series  may on behalf of the  Holders of all the
Securities of such series waive any past default  hereunder with respect to such
series and its consequences, except a default

          (1) in the payment of the  principal  of or any premium or interest on
     any Security of such series, or

          (2) in respect of a covenant or provision  hereof which under  Article
     Nine  cannot be  modified  or amended  without the consent of the Holder of
     each Outstanding Security of such series affected.

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

SECTION 514. UNDERTAKING FOR COSTS.

     In any  suit  for  the  enforcement  of any  right  or  remedy  under  this
Indenture,  or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an  undertaking to pay the costs of such suit, and may assess costs against
any such party  litigant,  in the manner and to the extent provided in the Trust
Indenture  Act;  PROVIDED that neither this Section nor the Trust  Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company or the Trustee.

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

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

SECTION 601. CERTAIN DUTIES AND RESPONSIBILITIES.

     The duties and  responsibilities of the Trustee shall be as provided by the
Trust  Indenture  Act.  Notwithstanding  the  foregoing,  no  provision  of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers,  if it shall have  reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not  reasonably  assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting  the  liability of or affording  protection to the Trustee shall be
subject to the provisions of this Section.

SECTION 602. NOTICE OF DEFAULTS.

     If a default occurs hereunder with respect to Securities of any series, the
Trustee  shall give the  Holders of  Securities  of such  series  notice of such
default as and to the extent  provided  by the Trust  Indenture  Act;  PROVIDED,
HOWEVER,  that in the case of any default of the character  specified in Section
501(4) with  respect to  Securities  of such  series,  no such notice to Holders
shall be given  until at least 30 days  after the  occurrence  thereof.  For the
purpose of this Section,  the term "default"  means any event which is, or after
notice or lapse of time or both would  become,  an Event of Default with respect
to Securities of such series.

SECTION 603. CERTAIN RIGHTS OF TRUSTEE.

     Subject to the provisions of Section 601:

          (1) the  Trustee  may  rely  and  shall  be  protected  in  acting  or

     instrument,  opinion, report, notice, request,  direction,  consent, order,
     bond,  debenture,  note,  other evidence of  indebtedness or other paper or
     document  believed by it to be genuine and to have been signed or presented

          (3) whenever in the administration of this Indenture the Trustee shall
     deem it desirable that a matter be proved or  established  prior to taking,
     suffering  or omitting  any action  hereunder,  the Trustee  (unless  other
     evidence  be herein  specifically  prescribed)  may,  in the absence of bad
     faith on its part, rely upon an Officers' Certificate;

          (4) the Trustee  may consult  with  counsel of its  selection  and the
     advice of such counsel or any Opinion of Counsel shall be full and complete
     authorization  and  protection in respect of any action taken,  suffered or
     omitted by it hereunder in good faith and in reliance thereon;

                                      -35-
<PAGE>
          (5) the Trustee  shall be under no  obligation  to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders pursuant to this Indenture, unless such Holders shall
     have offered to the Trustee  reasonable  security or indemnity  against the
     costs, expenses and liabilities which might be incurred by it in compliance
     with such request or direction;

          (6) the Trustee shall not be bound to make any investigation  into the
     facts  or  matters  stated  in  any  resolution,   certificate,  statement,
     instrument,  opinion, report, notice, request,  direction,  consent, order,
     bond,  debenture,  note,  other evidence of  indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation  into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or  investigation,  it
     shall be  entitled  to  examine  the books,  records  and  premises  of the
     Company, personally or by agent or attorney; and

          (7) the Trustee may execute any of the trusts or powers  hereunder  or
     perform any duties  hereunder  either  directly or by or through  agents or
     attorneys and the Trustee shall not be  responsible  for any  misconduct or
     negligence on the part of any agent or attorney  appointed with due care by
     it hereunder.

SECTION 604. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

     The recitals  contained herein and in the Securities,  except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating  Agent assumes any responsibility
for their  correctness.  The Trustee makes no representations as to the validity
or sufficiency of this Indenture or of the  Securities.  Neither the Trustee nor
any Authenticating  Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

SECTION 605. MAY HOLD SECURITIES.

     The Trustee,  any  Authenticating  Agent,  any Paying  Agent,  any Security
Registrar  or any other agent of the  Company,  in its  individual  or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
608 and 613, may  otherwise  deal with the Company with the same rights it would
have if it were  not  Trustee,  Authenticating  Agent,  Paying  Agent,  Security
Registrar or such other agent.

SECTION 606. MONEY HELD IN TRUST.

     Money held by the Trustee in trust  hereunder  need not be segregated  from
other funds except to the extent  required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

SECTION 607. COMPENSATION AND REIMBURSEMENT.

     The Company agrees

                                      -36-
<PAGE>
          (1) to pay to the Trustee from time to time such compensation as shall
     be agreed  to in  writing  between  the  Company  and the  Trustee  for all
     services rendered by it hereunder (which  compensation shall not be limited
     by any  provision of law in regard to the  compensation  of a trustee of an
     express trust);

          (2) except as otherwise  expressly  provided herein,  to reimburse the
     Trustee upon its request for all  reasonable  expenses,  disbursements  and
     advances  incurred or made by the Trustee in accordance  with any provision
     of this Indenture  (including the reasonable  compensation and the expenses
     and  disbursements  of its agents and  counsel),  except any such  expense,
     disbursement  or advance as may be  attributable  to its  negligence or bad
     faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss,  liability or expense incurred without negligence or bad faith on its
     part, arising out of or in connection with the acceptance or administration
     of the trust or trusts  hereunder,  including  the  costs and  expenses  of
     defending  itself  against any claim or  liability in  connection  with the
     exercise or performance of any of its powers or duties hereunder.

     The Trustee shall have a lien prior to the Securities upon all property and
funds held by it hereunder  for any amount owing it or any  predecessor  Trustee
pursuant to this Section 607, except with respect to funds held in trust for the
benefit of the Holders of particular Securities.

     Without  limiting any rights available to the Trustee under applicable law,
when the Trustee incurs expenses or renders services in connection with an Event
of  Default  specified  in  Section  501(5)  or  Section  501(6),  the  expenses
(including  the  reasonable  charges  and  expenses  of  its  counsel)  and  the
compensation   for  the  services  are  intended  to   constitute   expenses  of
administration  under any applicable Federal or State bankruptcy,  insolvency or
other similar law.

     The  provisions  of this  Section  shall  survive the  termination  of this
Indenture.

SECTION 608. CONFLICTING INTERESTS.

     If the  Trustee  has or shall  acquire a  conflicting  interest  within the
meaning of the Trust  Indenture  Act, the Trustee  shall either  eliminate  such
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.  To the extent
permitted  by such Act,  the Trustee  shall not be deemed to have a  conflicting
interest  by virtue of being a trustee  under  this  Indenture  with  respect to
Securities of more than one series.

SECTION 609. CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

     There  shall at all  times be one (and  only one)  Trustee  hereunder  with
respect to the  Securities  of each series,  which may be Trustee  hereunder for
Securities of one or more other  series.  Each Trustee shall be a Person that is
eligible  pursuant to the Trust  Indenture Act to act as such and has a combined
capital  and  surplus  of at least  $50,000,000.  If any such  Person  publishes
reports of condition at least annually,  pursuant to law or to the  requirements
of its supervising or examining authority, then for the purposes of this Section
and to the extent permitted by the Trust Indenture Act, the combined capital and

                                      -37-
<PAGE>
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  with  respect to the  Securities  of any series  shall cease to be
eligible in accordance  with the  provisions  of this  Section,  it shall resign
immediately  in the  manner and with the effect  hereinafter  specified  in this
Article.

SECTION 610. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     No  resignation or removal of the Trustee and no appointment of a successor
Trustee  pursuant to this Article shall become effective until the acceptance of
appointment  by  the  successor   Trustee  in  accordance  with  the  applicable
requirements of Section 611.

     The Trustee may resign at any time with respect to the Securities of one or
more series by giving written  notice thereof to the Company.  If the instrument
of acceptance by a successor Trustee required by Section 611 shall not have been
delivered  to the  Trustee  within 30 days  after the  giving of such  notice of
resignation,   the  resigning  Trustee  may  petition  any  court  of  competent
jurisdiction  for the  appointment  of a successor  Trustee  with respect to the
Securities of such series.

     The Trustee may be removed at any time with  respect to the  Securities  of
any  series by Act of the  Holders  of a  majority  in  principal  amount of the
Outstanding  Securities  of such  series,  delivered  to the  Trustee and to the
Company.

     If at any time:

          (1) the Trustee  shall fail to comply with  Section 608 after  written
     request  therefor  by the Company or by any Holder who has been a bona fide
     Holder of a Security for at least six months, or

          (2) the Trustee shall cease to be eligible under Section 609 and shall
     fail to resign after written request therefor by the Company or by any such
     Holder, or

          (3) 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,  (A) the Company by a Board  Resolution  may remove the
Trustee  with  respect to all  Securities,  or (B) subject to Section  514,  any
Holder  who has been a bona fide  Holder of a  Security  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  with respect to all
Securities and the appointment of a successor Trustee or Trustees.

     If the Trustee shall resign,  be removed or become incapable of acting,  or
if a vacancy shall occur in the office of Trustee for any cause, with respect to
the Securities of one or more series, the Company, by a Board Resolution,  shall
promptly appoint a successor  Trustee or Trustees with respect to the Securities
of that or those series (it being understood that any such successor Trustee may

                                      -38-
<PAGE>
be appointed with respect to the Securities of one or more or all of such series
and  that at any  time  there  shall be only one  Trustee  with  respect  to the
Securities  of any  particular  series)  and shall  comply  with the  applicable
requirements of Section 611. If, within one year after such resignation, removal
or  incapability,  or the occurrence of such vacancy,  a successor  Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal  amount of the Outstanding  Securities of such series
delivered  to the Company and the retiring  Trustee,  the  successor  Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable  requirements of Section 611,  become the successor  Trustee
with respect to the  Securities of such series and to that extent  supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the  Securities  of any series shall have been so appointed by the Company or
the Holders and accepted  appointment in the manner required by Section 611, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent  jurisdiction for the appointment of a successor  Trustee
with respect to the Securities of such series.

     The Company shall give notice of each  resignation  and each removal of the
Trustee with respect to the  Securities of any series and each  appointment of a
successor Trustee with respect to the Securities of any series to all Holders of
Securities  of such series in the manner  provided in Section  106.  Each notice
shall include the name of the successor  Trustee with respect to the  Securities
of such series and the address of its Corporate Trust Office.

SECTION 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     In case of the appointment hereunder of a successor Trustee with respect to
all  Securities,  every such  successor  Trustee  so  appointed  shall  execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting  such  appointment,  and thereupon the  resignation  or removal of the
retiring Trustee shall become effective and such successor Trustee,  without any
further  act,  deed or  conveyance,  shall  become  vested  with all the rights,
powers,  trusts and duties of the retiring  Trustee;  but, on the request of the
Company or the successor  Trustee,  such retiring Trustee shall, upon payment of
its charges,  execute and deliver an instrument  transferring  to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign,  transfer and deliver to such  successor  Trustee all property and money
held by such retiring Trustee hereunder.

     In case of the appointment hereunder of a successor Trustee with respect to
the  Securities of one or more (but not all) series,  the Company,  the retiring
Trustee and each successor Trustee with respect to the Securities of one or more
series shall execute and deliver an indenture  supplemental  hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor  Trustee relates,  (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed  necessary or desirable to confirm that all the rights,  powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring  Trustee is not retiring shall continue
to be vested in the retiring Trustee,  and (3) shall add to or change any of the
provisions of this  Indenture as shall be necessary to provide for or facilitate

                                      -39-
<PAGE>
the  administration  of the trusts hereunder by more than one Trustee,  it being
understood  that  nothing  herein  or  in  such  supplemental   indenture  shall
constitute  such  Trustees  co-trustees  of the same  trust  and that  each such
Trustee shall be trustee of a trust or trusts hereunder  separate and apart from
any trust or trusts hereunder  administered by any other such Trustee;  and upon
the execution and delivery of such  supplemental  indenture the  resignation  or
removal of the retiring  Trustee shall become  effective to the extent  provided
therein  and each such  successor  Trustee,  without any  further  act,  deed or
conveyance,  shall become vested with all the rights,  powers, trusts and duties
of the retiring  Trustee with respect to the  Securities of that or those series
to which the appointment of such successor  Trustee relates;  but, on request of
the Company or any successor  Trustee,  such retiring Trustee shall duly assign,
transfer  and deliver to such  successor  Trustee all property and money held by
such retiring Trustee  hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

     Upon request of any such successor  Trustee,  the Company shall execute any
and all  instruments  for more fully and certainly  vesting in and confirming to
such  successor  Trustee all such rights,  powers and trusts  referred to in the
first or second preceding paragraph, as the case may be.

     No successor  Trustee  shall accept its  appointment  unless at the time of
such  acceptance  such  successor  Trustee shall be qualified and eligible under
this Article.

SECTION 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     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 the corporate trust business
of the Trustee,  shall be the successor of the Trustee hereunder,  provided such
corporation  shall be  otherwise  qualified  and  eligible  under this  Article,
without the  execution  or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not  delivered,  by the Trustee  then in office,  any  successor  by merger,
conversion  or  consolidation  to such  authenticating  Trustee  may adopt  such
authentication  and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

SECTION 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     If and when the  Trustee  shall be or become a creditor  of the Company (or
any other  obligor  upon the  Securities),  the Trustee  shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

SECTION 614. APPOINTMENT OF AUTHENTICATING AGENT.

     The Trustee may appoint an  Authenticating  Agent or Agents with respect to
one or more series of  Securities  which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue
and upon exchange,  registration  of transfer or partial  redemption  thereof or
pursuant to Section 306, and  Securities so  authenticated  shall be entitled to
the  benefits  of this  Indenture  and  shall be valid  and  obligatory  for all
purposes as if authenticated  by the Trustee  hereunder.  Wherever  reference is

                                      -40-
<PAGE>
made in this Indenture to the  authentication  and delivery of Securities by the
Trustee or the Trustee's certificate of authentication,  such reference shall be
deemed to include  authentication  and  delivery  on behalf of the Trustee by an
Authenticating  Agent and a certificate of authentication  executed on behalf of
the  Trustee by an  Authenticating  Agent.  Each  Authenticating  Agent shall be
acceptable to the Company and shall at all times be a corporation  organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent,  having a combined  capital and surplus of not less than  $50,000,000 and
subject to supervision or  examination  by Federal or State  authority.  If such
Authenticating Agent publishes reports of condition at least annually,  pursuant
to law or to the requirements of said supervising or examining  authority,  then
for the  purposes  of this  Section,  the  combined  capital and surplus of such
Authenticating  Agent shall be deemed to be its combined  capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  such Authenticating  Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

     An  Authenticating  Agent may resign at any time by giving  written  notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an  Authenticating  Agent by giving written notice thereof to such
Authenticating  Agent  and to the  Company.  Upon  receiving  such a  notice  of
resignation  or  upon  such  a  termination,   or  in  case  at  any  time  such
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  the Trustee may appoint a successor  Authenticating
Agent  which  shall be  acceptable  to the Company and shall give notice of such
appointment  in the manner  provided in Section 106 to all Holders of Securities
of the series with respect to which such  Authenticating  Agent will serve.  Any
successor  Authenticating  Agent upon  acceptance of its  appointment  hereunder
shall become  vested with all the rights,  powers and duties of its  predecessor
hereunder,  with like effect as if originally named as an Authenticating  Agent.
No successor  Authenticating  Agent shall be appointed unless eligible under the
provisions of this Section.

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

     If an  appointment  with respect to one or more series is made  pursuant to
this  Section,  the  Securities  of such series may have  endorsed  thereon,  in
addition  to  the  Trustee's  certificate  of  authentication,   an  alternative
certificate of authentication in the following form:

     This is one of the Securities of the series designated  therein referred to
in the within-mentioned Indenture.

     Indenture, or

                                    COVENANTS

SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

     The  Company  covenants  and  agrees  for the  benefit  of each  series  of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the  Securities of that series in  accordance  with the terms of
the Securities and this Indenture.

SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY.

     The  Company  will  maintain  in each  Place of  Payment  for any series of
Securities an office or agency where  Securities of that series may be presented
or surrendered for payment,  where  Securities of that series may be surrendered
for  registration  of transfer or exchange  and where  notices and demands to or
upon the Company in respect of the  Securities of that series and this Indenture
may be served. The Company will 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  required  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

                                      -47-
<PAGE>
Office of the Trustee,  and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time  designate one or more other offices
or  agencies  where the  Securities  of one or more series may be  presented  or
surrendered  for any or all such purposes and may from time to time rescind such
designations; PROVIDED, HOWEVER, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for  Securities  of any series for such  purposes.  The
Company will 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.

SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

     If the Company  shall at any time act as its own Paying  Agent with respect
to any  series  of  Securities,  it  will,  on or  before  each  due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate  and hold in trust for the benefit of the Persons  entitled  thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided  and will  promptly  notify the  Trustee of its action or failure so to
act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities,  it will,  prior to each due date of the principal of or any premium
or interest on any Securities of that series,  deposit with a Paying Agent a sum
sufficient  to pay such  amount,  such sum to be held as  provided  by the Trust
Indenture  Act,  and (unless  such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

     The Company will cause each Paying Agent for any series of Securities other
than the Trustee to execute and  deliver to the Trustee an  instrument  in which
such Paying Agent shall agree with the  Trustee,  subject to the  provisions  of
this Section,  that such Paying Agent will (1) comply with the provisions of the
Trust  Indenture  Act  applicable  to it as a Paying  Agent and (2)  during  the
continuance  of any  default  by the  Company  (or any  other  obligor  upon the
Securities  of that  series)  in the  making of any  payment  in  respect of the
Securities of that series,  upon the written  request of the Trustee,  forthwith
pay to the Trustee  all sums held in trust by such  Paying  Agent for payment in
respect of the Securities of that series.

     The Company may at any time, for the purpose of obtaining the  satisfaction
and  discharge of this  Indenture or for any other  purpose,  pay, or by Company
Order  direct any Paying  Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying  Agent,  such sums to be held by the Trustee upon the
same  trusts as those  upon  which  such sums were held by the  Company  or such
Paying Agent;  and,  upon such payment by any Paying Agent to the Trustee,  such
Paying Agent shall be released from all further  liability  with respect to such
money.

     Any money  deposited with the Trustee or any Paying Agent,  or then held by
the  Company,  in trust for the  payment of the  principal  of or any premium or
interest on any  Security of any series and  remaining  unclaimed  for two years
after such  principal,  premium or interest has become due and payable  shall be

                                      -48-
<PAGE>
paid to the Company on Company  Request,  or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor,  look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money,  and all  liability of the Company as trustee  thereof,  shall  thereupon
cease;  PROVIDED,  HOWEVER,  that the Trustee or such Paying Agent, before being
required to make any such repayment,  may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published  on each  Business  Day and of general  circulation  in the Borough of
Manhattan,  The City of New York,  New York,  notice  that  such  money  remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such  publication,  any unclaimed balance of such money
then remaining will be repaid to the Company.

SECTION 1004. STATEMENT BY OFFICERS AS TO DEFAULT.

     The Company will  deliver to the Trustee,  within 120 days after the end of
each fiscal year of the  Company  ending  after the date  hereof,  an  Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions  and conditions of this  Indenture  (without  regard to any period of
grace or requirement of notice provided  hereunder) and, if the Company shall be
in default,  specifying  all such defaults and the nature and status  thereof of
which they may have knowledge.

SECTION 1005. EXISTENCE.

     Subject  to  Article  Eight,  the  Company  will do or cause to be done all
things  necessary to preserve  and keep in full force and effect its  existence,
rights  (charter and  statutory) and  franchises;  PROVIDED,  HOWEVER,  that the
Company  shall not be required to preserve  any such right or  franchise  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 that the loss
thereof is not disadvantageous in any material respect to the Holders.

SECTION 1006. MAINTENANCE OF PROPERTIES.

     The Company will cause all properties  used or useful in the conduct of its
business or the business of any  Subsidiary  to be  maintained  and kept in good
condition,  repair and working order and supplied  with all necessary  equipment
and  will  cause  to be made  all  necessary  repairs,  renewals,  replacements,
betterments and improvements  thereof, all as in the judgment of the Company may
be necessary  so that the business  carried on in  connection  therewith  may be
properly and  advantageously  conducted at all times;  PROVIDED,  HOWEVER,  that
nothing in this  Section  shall  prevent  the  Company  from  discontinuing  the
operation or maintenance of any of such properties if such discontinuance is, in
the  judgment of the  Company,  desirable  in the conduct of its business or the
business of any Subsidiary and not  disadvantageous  in any material  respect to
the Holders.

<PAGE>
SECTION 1007.  PAYMENT OF TAXES AND OTHER CLAIMS.

     The Company will pay or discharge or cause to be paid or discharged, before
the same shall become  delinquent,  (1) all taxes,  assessments and governmental
charges levied or imposed upon the Company or any Subsidiary or upon the income,
profits or property of the Company or any Subsidiary,  and (2) all lawful claims
for labor,  materials and supplies which, if unpaid,  might by law become a lien
upon the property of the Company or any Subsidiary;  PROVIDED, HOWEVER, that the
Company  shall  not be  required  to pay or  discharge  or  cause  to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

SECTION 1008. WAIVER OF CERTAIN COVENANTS.

     Except as otherwise specified as contemplated by Section 301 for Securities
of such series,  the Company may, with respect to the  Securities of any series,
omit in any particular instance to comply with any term,  provision or condition
set forth in any covenant provided pursuant to Section 301(19), 901(2) or 901(7)
for the benefit of the Holders of such series or in any of Sections 1006 through
1007 if before the time for such  compliance  the Holders of at least 66-2/3% in
principal  amount of the Outstanding  Securities of such series shall, by Act of
such Holders,  either waive such  compliance in such instance or generally waive
compliance  with such term,  provision  or  condition,  but no such waiver shall
extend to or affect such term,  provision or  condition  except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the  Company  and the  duties of the  Trustee  in  respect  of any such term,
provision or condition shall remain in full force and effect.

SECTION 1009. CALCULATION OF ORIGINAL ISSUE DISCOUNT.

     The  Company  shall  file  with  the  Trustee  promptly  at the end of each
calendar year a written notice  specifying the amount of original issue discount
(including daily rates and accrual periods) accrued on Outstanding Securities as
of the end of such year.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

SECTION 1101. APPLICABILITY OF ARTICLE.

     Securities of any series which are redeemable  before their Stated Maturity
shall be  redeemable  in  accordance  with their terms and (except as  otherwise
specified as contemplated by Section 301 for such Securities) in accordance with
this Article.

SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The election of the Company to redeem any Securities  shall be evidenced by
a Board Resolution or in another manner specified as contemplated by Section 301
for such  Securities.  In case of any redemption at the election of the Company,
the Company shall,  at least 60 days prior to the  Redemption  Date fixed by the
Company (unless a shorter notice shall be  satisfactory to the Trustee),  notify
the Trustee of such  Redemption  Date, of the principal  amount of Securities of
such series to be redeemed and, if applicable, of the tenor of the Securities to
be  redeemed.  In the case of any  redemption  of  Securities  (a)  prior to the

                                      -50-
<PAGE>
expiration of any restriction on such  redemption  provided in the terms of such
Securities or elsewhere in this Indenture, or (b) pursuant to an election of the
Company  which  is  subject  to a  condition  specified  in the  terms  of  such
Securities or elsewhere in this Indenture, the Company shall furnish the Trustee
with an Officers'  Certificate  evidencing  compliance with such  restriction or
condition.

SECTION 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

     If less than all the  Securities  of any series are to be redeemed  (unless
all the Securities of such series and of a specified tenor are to be redeemed or
unless  such  redemption  affects  only  a  single  Security),   the  particular
Securities  to be redeemed  shall be selected not more than 60 days prior to the
Redemption Date by the Trustee,  from the Outstanding  Securities of such series
not previously  called for redemption,  by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the  principal  amount of any Security of such series,  PROVIDED that
the  unredeemed  portion of the principal  amount of any Security shall be in an
authorized  denomination  (which  shall not be less than the minimum  authorized
denomination) for such Security.  If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security),  the particular  Securities to be redeemed shall be selected
not more than 60 days  prior to the  Redemption  Date by the  Trustee,  from the
Outstanding  Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

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

     The provisions of the two preceding paragraphs shall not apply with respect
to any redemption affecting only a single Security,  whether such Security is to
be redeemed in whole or in part. In the case of any such redemption in part, the
unredeemed  portion  of the  principal  amount  of the  Security  shall be in an
authorized  denomination  (which  shall not be less than the minimum  authorized
denomination) for such Security.

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

SECTION 1104. NOTICE OF REDEMPTION.

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

     All notices of  redemption  shall  identify the  Securities  to be redeemed
(including CUSIP number) and shall state:

          (1) the Redemption Date,

                                      -51-
<PAGE>
          (2) the Redemption Price,

          (3) if less than all the Outstanding Securities of any series and of a
     specified  tenor  consisting  of  more  than a  single  Security  are to be
     redeemed, the identification (and, in the case of partial redemption of any
     such Securities,  the principal amounts) of the particular Securities to be
     redeemed and, if less than all the Outstanding Securities of any series and
     of a specified  tenor  consisting of a single  Security are to be redeemed,
     the principal amount of the particular Security to be redeemed,

          (4) that on the Redemption  Date the Redemption  Price will become due
     and payable upon each such Security to be redeemed and, if applicable, that
     interest thereon will cease to accrue on and after said date,

          (5) the place or places where each such Security is to be  surrendered
     for payment of the Redemption Price, and

          (6) that the redemption is for a sinking fund, if such is the case.

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

SECTION 1105. DEPOSIT OF REDEMPTION PRICE.

     Prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying  Agent (or,  if the  Company  is acting as its own  Paying  Agent,
segregate  and hold in trust as  provided  in  Section  1003) an amount of money
sufficient to pay the Redemption  Price of, and (except if the  Redemption  Date
shall be an Interest Payment Date) accrued interest on, all the Securities which
are to be redeemed on that date.

SECTION 1106. SECURITIES PAYABLE ON REDEMPTION DATE.

     Notice of redemption  having been given as aforesaid,  the Securities so to
be  redeemed  shall,  on the  Redemption  Date,  become  due and  payable at the
Redemption  Price  therein  specified,  and from and after such date (unless the
Company  shall  default  in the  payment  of the  Redemption  Price and  accrued
interest) such  Securities  shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption  Price,  together with accrued interest
to the Redemption Date; PROVIDED,  HOWEVER,  that, unless otherwise specified as
contemplated  by Section 301,  installments of interest whose Stated Maturity is
on or prior to the  Redemption  Date  will be  payable  to the  Holders  of such
Securities,  or one or more  Predecessor  Securities,  registered as such at the
close of business on the relevant  Record Dates according to their terms and the
provisions of Section 307.

     If any Security  called for redemption  shall not be so paid upon surrender
thereof for  redemption,  the principal and any premium shall,  until paid, bear
interest  from  the  Redemption  Date at the  rate  prescribed  therefor  in the
Security.

SECTION 1107. SECURITIES REDEEMED IN PART.

     Any Security which is to be redeemed only in part shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires,  due
endorsement by, or a written  instrument of transfer in form satisfactory to the
Company and the Trustee  duly  executed  by, the Holder  thereof or his attorney
duly  authorized  in writing),  and the Company shall  execute,  and the Trustee
shall  authenticate  and deliver to the Holder of such Security  without service
charge,  a new Security or Securities  of the same series and of like tenor,  of
any authorized  denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the  unredeemed  portion of the principal of
the Security so surrendered.

                                  SINKING FUNDS

SECTION 1201. APPLICABILITY OF ARTICLE.

     The  provisions of this Article shall be applicable to any sinking fund for
the  retirement of  Securities  of any series  except as otherwise  specified as
contemplated by Section 301 for such Securities.

     The minimum amount of any sinking fund payment provided for by the terms of
any Securities is herein referred to as a "mandatory sinking fund payment",  and
any payment in excess of such minimum  amount  provided for by the terms of such
Securities  is herein  referred to as an  "optional  sinking fund  payment".  If
provided for by the terms of any Securities, the cash amount of any sinking fund
payment may be subject to  reduction as provided in Section  1202.  Each sinking
fund payment shall be applied to the redemption of Securities as provided for by
the terms of such Securities.

SECTION 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

     The Company (1) may deliver Outstanding  Securities of a series (other than
any previously  called for redemption) and (2) may apply as a credit  Securities
of a series  which have been  redeemed  either at the  election  of the  Company
pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in each
case in satisfaction of all or any part of any sinking fund payment with respect
to any  Securities  of such series  required to be made pursuant to the terms of
such  Securities  as and to the  extent  provided  for  by  the  terms  of  such
Securities;  PROVIDED  that  the  Securities  to be so  credited  have  not been
previously so credited.  The  Securities to be so credited shall be received and
credited for such purpose by the Trustee at the Redemption  Price,  as specified
in the  Securities so to be redeemed,  for redemption  through  operation of the
sinking  fund and the  amount of such  sinking  fund  payment  shall be  reduced
accordingly.

SECTION 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

     Not less  than 60 days  prior to each  sinking  fund  payment  date for any
Securities,  the Company will  deliver to the Trustee an  Officers'  Certificate

                                      -53-
<PAGE>
specifying  the  amount  of the  next  ensuing  sinking  fund  payment  for such
Securities  pursuant to the terms of such Securities,  the portion  thereof,  if
any,  which is to be  satisfied by payment of cash and the portion  thereof,  if
any, which is to be satisfied by delivering and crediting Securities pursuant to
Section 1202 and stating the basis for such credit and that such Securities have
not been  previously  so  credited  and will also  deliver  to the  Trustee  any
Securities to be so delivered.  Not less than 30 days prior to each such sinking
fund payment date,  the Trustee shall select the  Securities to be redeemed upon
such sinking fund payment date in the manner specified in Section 1103 and cause
notice of the  redemption  thereof to be given in the name of and at the expense
of the Company in the manner  provided in Section 1104.  Such notice having been
duly given,  the redemption of such Securities  shall be made upon the terms and
in the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301. Company's Option to Effect Defeasance or Covenant Defeasance.

     The Company may elect,  at its option at any time,  to have Section 1302 or
Section 1303 applied to any Securities or any series of Securities,  as the case
may be, designated  pursuant to Section 301 as being defeasible pursuant to such
Section 1302 or 1303, in accordance  with any applicable  requirements  provided
pursuant to Section 301 and upon  compliance with the conditions set forth below
in this Article.  Any such election shall be evidenced by a Board  Resolution or
in another manner specified as contemplated by Section 301 for such Securities.

SECTION 1302. DEFEASANCE AND DISCHARGE.

     Upon the  Company's  exercise  of its option (if any) to have this  Section
applied to any Securities or any series of  Securities,  as the case may be, the
Company  shall be deemed  to have  been  discharged  from its  obligations  with
respect to such Securities as provided in this Section on and after the date the
conditions  set  forth  in  Section  1304  are  satisfied   (hereinafter  called
"Defeasance"). For this purpose, such Defeasance means that the Company shall be
deemed to have paid and discharged the entire  indebtedness  represented by such
Securities and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company,  shall execute proper instruments  acknowledging the
same),  subject to the following which shall survive until otherwise  terminated
or  discharged  hereunder:  (1) the  rights of  Holders  of such  Securities  to
receive,  solely from the trust fund described in Section 1304 and as more fully
set forth in such  Section,  payments  in  respect of the  principal  of and any
premium and interest on such Securities when payments are due, (2) the Company's
obligations  with respect to such Securities  under Sections 304, 305, 306, 1002
and 1003,  and with  respect to the Trustee  under  Section 607, (3) the rights,
powers,  trusts,  duties and  immunities  of the Trustee  hereunder and (4) this
Article.  Subject to compliance with this Article,  the Company may exercise its
option (if any) to have this Section  applied to any Securities  notwithstanding
the prior  exercise of its option (if any) to have  Section 1303 applied to such
Securities.

                                      -54-
<PAGE>
SECTION 1303. COVENANT DEFEASANCE.

     Upon the  Company's  exercise  of its option (if any) to have this  Section
applied to any Securities or any series of  Securities,  as the case may be, (1)
the  Company  shall be  released  from its  obligations  under  Section  801(3),
Sections 1006 through 1007,  inclusive,  and any covenants  provided pursuant to
Section 301(19), 901(2), 901(6) or 901(7) for the benefit of the Holders of such
Securities  and (2) the  occurrence  of any event  specified in Sections  501(4)
(with respect to any of Section 801(3),  Sections 1006 through 1007,  inclusive,
and any such covenants provided pursuant to Section 301(19),  901(2),  901(6) or
901(7))  and  501(7)  shall be deemed not to be or result in an Event of Default
with  respect to such  Securities  as provided in this  Section on and after the
date the conditions set forth in Section 1304 are satisfied  (hereinafter called
"Covenant  Defeasance").  For this purpose, such Covenant Defeasance means that,
with respect to such  Securities,  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  specified  Section (to the extent so  specified in the case of Section
501(4)),  whether  directly or indirectly  by reason of any reference  elsewhere
herein to any such Section or by reason of any  reference in any such Section to
any other provision  herein or in any other document,  but the remainder of this
Indenture and such Securities shall be unaffected thereby.

SECTION 1304. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

     The following shall be the conditions to the application of Section 1302 or
Section 1303 to any Securities or any series of Securities, as the case may be:

          (1) The  Company  shall  irrevocably  have  deposited  or caused to be
     deposited  with the  Trustee  as trust  funds in trust for the  purpose  of
     making the following  payments,  specifically  pledged as security for, and
     dedicated  solely to, the  benefit of the Holders of such  Securities,  (A)
     money in an amount,  or (B) U.S.  Government  Obligations which through the
     scheduled   payment  of  principal  and  interest  in  respect  thereof  in
     accordance with their terms will provide, not later than one day before the
     due date of any payment,  money in an amount, or (C) a combination thereof,
     in each case sufficient,  in the opinion of a nationally recognized firm of
     independent public accountants expressed in a written certification thereof
     delivered to the Trustee, to pay and discharge,  and which shall be applied
     by the Trustee to pay and  discharge,  the principal of and any premium and
     interest on such Securities on the respective  Stated  Maturities or on any
     Redemption  Date  established  pursuant to clause (9) below,  in accordance
     with the terms of this Indenture and such Securities. As used herein, "U.S.
     Government  Obligation"  means  (x)  any  security  which  is (i) a  direct
     obligation  of the United  States of America  for the  payment of which the
     full faith and credit of the United States of America is pledged or (ii) an
     obligation of a Person  controlled or supervised by and acting as an agency
     or  instrumentality of the United States of America the payment of which is
     unconditionally  guaranteed  as a full faith and credit  obligation  by the
     United  States  of  America,  which,  in  either  case (i) or (ii),  is not
     callable or  redeemable  at the option of the issuer  thereof,  and (y) any
     depositary  receipt issued by a bank (as defined in Section  3(a)(2) of the
     Securities Act) as custodian with respect to any U.S. Government Obligation
     which is  specified  in  Clause  (x)  above  and held by such  bank for the
     account of the holder of such  depositary  receipt,  or with respect to any
     specific  payment  of  principal  of or  interest  on any  U.S.  Government
     Obligation  which is so  specified  and  held,  PROVIDED  that  (except  as
     required by law) such  custodian is not  authorized  to make any  deduction
     from the amount payable to the holder of such  depositary  receipt from any

                                      -55-
<PAGE>
     amount  received  by  the  custodian  in  respect  of the  U.S.  Government
     Obligation  or the specific  payment of principal or interest  evidenced by
     such depositary receipt.

          (2) In the event of an  election  to have  Section  1302  apply to any
     Securities  or any series of  Securities,  as the case may be, the  Company
     shall have delivered to the Trustee an Opinion of Counsel  stating that (A)
     the Company has received from, or there has been published by, the Internal
     Revenue  Service a ruling or (B) since the date of this  instrument,  there
     has been a change in the applicable  Federal income tax law, in either case
     (A) or (B) to the effect that, and based thereon such opinion shall confirm
     that,  the Holders of such  Securities  will not recognize gain or loss for
     Federal  income tax  purposes as a result of the  deposit,  Defeasance  and
     discharge  to be  effected  with  respect  to such  Securities  and will be
     subject to Federal income tax on the same amount, in the same manner and at
     the  same  times  as would  be the  case if such  deposit,  Defeasance  and
     discharge were not to occur.

          (3) In the event of an  election  to have  Section  1303  apply to any
     Securities  or any series of  Securities,  as the case may be, the  Company
     shall  have  delivered  to the  Trustee an Opinion of Counsel to the effect
     that the Holders of such  Securities  will not  recognize  gain or loss for
     Federal  income  tax  purposes  as a result  of the  deposit  and  Covenant
     Defeasance  to be  effected  with  respect to such  Securities  and will be
     subject to Federal income tax on the same amount, in the same manner and at
     the same times as would be the case if such deposit and Covenant Defeasance
     were not to occur.

          (4) The  Company  shall have  delivered  to the  Trustee an  Officers'
     Certificate  to the  effect  that  neither  such  Securities  nor any other
     Securities of the same series,  if then listed on any securities  exchange,
     will be delisted as a result of such deposit.

          (5) No event which is, or after  notice or lapse of time or both would
     become,  an Event of Default with respect to such  Securities  or any other
     Securities  shall  have  occurred  and be  continuing  at the  time of such
     deposit or, with regard to any such event  specified in Sections 501(5) and
     (6), at any time on or prior to the 90th day after the date of such deposit
     (it being  understood  that this  condition  shall not be deemed  satisfied
     until after such 90th day).

          (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee
     to have a conflicting  interest  within the meaning of the Trust  Indenture
     Act  (assuming  all  Securities  are in default  within the meaning of such
     Act).

          (7) Such  Defeasance  or  Covenant  Defeasance  shall not  result in a
     breach or violation of, or constitute a default under,  any other agreement
     or instrument to which the Company is a party or by which it is bound.

          (8) Such  Defeasance  or Covenant  Defeasance  shall not result in the
     trust arising from such deposit  constituting an investment  company within
     the  meaning  of the  Investment  Company  Act unless  such trust  shall be
     registered under such Act or exempt from registration thereunder.

                                      -56-
<PAGE>
          (9) If the  Securities  are to be  redeemed  prior to Stated  Maturity
     (other than from  mandatory  sinking fund payments or analogous  payments),
     notice of such  redemption  shall  have been duly  given  pursuant  to this
     Indenture or provision therefor satisfactory to the Trustee shall have been
     made.

          (10) The Company  shall have  delivered  to the  Trustee an  Officers'
     Certificate  and an Opinion of Counsel,  each stating  that all  conditions
     precedent with respect to such Defeasance or Covenant  Defeasance have been
     complied with.

SECTION 1305. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
              TRUST; MISCELLANEOUS PROVISIONS.

     Subject to the  provisions of the last paragraph of Section 1003, all money
and U.S. Government  Obligations (including the proceeds thereof) deposited with
the Trustee  pursuant to Section 1304 in respect of any Securities shall be held
in trust and applied by the Trustee,  in accordance  with the provisions of such
Securities and this  Indenture,  to the payment,  either directly or through any
such Paying Agent  (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Holders of such Securities, of all sums due and to
become due thereon in respect of  principal  and any premium and  interest,  but
money so held in trust need not be  segregated  from other  funds  except to the
extent required by law.

     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 1304 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 Securities.

     Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon  Company  Request any money
or U.S.  Government  Obligations  held by it as  provided  in Section  1304 with
respect to any Securities which, in the opinion of a nationally  recognized firm
of independent public accountants  expressed in a written  certification thereof
delivered to the Trustee,  are in excess of the amount  thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance,  as
the case may be, with respect to such Securities.

SECTION 1306. REINSTATEMENT.

     If the  Trustee  or the  Paying  Agent  is  unable  to apply  any  money in
accordance  with this Article with  respect to any  Securities  by reason of any
order or judgment of any court or governmental authority enjoining,  restraining
or otherwise  prohibiting  such  application,  then the  obligations  under this
Indenture  and such  Securities  from which the Company has been  discharged  or
released  pursuant to Section  1302 or 1303 shall be revived and  reinstated  as

                                      -57-
<PAGE>
though no deposit had  occurred  pursuant to this  Article  with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1305 with respect to such Securities
in accordance with this Article;  PROVIDED,  HOWEVER,  that if the Company makes
any payment of  principal  of or any  premium or  interest on any such  Security
following such reinstatement of its obligations, the Company shall be subrogated
to the rights (if any) of the Holders of such Securities to receive such payment
from the money so held in trust.

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

     This  instrument  may be  executed in any number of  counterparts,  each of
which so executed shall be deemed to be an original,  but all such  counterparts
shall together constitute but one and the same instrument.

     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Indenture to be
duly executed as of the day and year first above written.
