condition or covenant provided for in this Indenture shall include:

          In any case where several matters are required to be certified by,

Person, or that they be so certified or covered by only one document, but one

of, or representations by, counsel,

that the certificate or opinion or representations with respect to the 
matters upon which his certificate or opinion is based are erroneous.  Any 
such certificate or opinion of counsel may be based, insofar as it relates to 
factual matters, upon a certificate or opinion of, or representations by, an

to such factual matters is in the possession of the Company, unless such 
counsel knows, or in the exercise of reasonable care should know, that the 
certificate or opinion or representations with respect to such matters are 
erroneous.
          Where any Person is required to make, give or execute two or more 
applications, requests, consents, certificates, statements, opinions or other 
instruments under this Indenture, they may, but need not, be consolidated and

SECTION 104.   ACTS OF HOLDERS; RECORD DATES.
          (a)  Any request, demand, authorization, direction, notice, 
consent, waiver or other action provided by this Indenture to be given 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 an 
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.
          (b)  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 or the 
Company, as the case may be, deems sufficient.
          (c)  The Company may, in the circumstances permitted by the Trust 
Indenture Act, fix any day as the record date for the purpose of determining 
the Holders of Outstanding 
                                     -15-
Convertible Debentures entitled to give, make or take any request, demand, 
authorization, direction, notice, consent, waiver or other action, or to vote 
on any action, authorized or permitted to be given or taken by Holders.  If 
not set by the Company prior to the first solicitation of a Holder made by 
any Person in respect of any such action, or, in the case of any such vote, 
prior to such vote, the record date for any such action or vote shall be the 
30th day (or, if later, the date of the most recent list of Holders required 
to be provided pursuant to Section 701) prior to such first solicitation or 
vote, as the case may be.  With regard to any record date, only the Holders 
on such date (or their duly designated proxies) shall be entitled to give or 
take, or vote on, the relevant action.
          (d)  The ownership of Convertible Debentures shall be proved by the 
Security Register.
          (e)  Any request, demand, authorization, direction, notice, 
consent, waiver or other Act of the Holder of any Convertible Debenture shall 
bind every future Holder of the same Convertible Debenture and the Holder of 
every Convertible Debenture 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 Convertible 
Debenture.
Without limiting the foregoing, a Holder entitled hereunder to give or take 
any such action with regard to any particular Convertible Debenture may do so 
with regard to all or any part of the principal amount of such Convertible 
Debenture or by one or more duly appointed agents each of which may do so 
pursuant to such appointment with regard to all or any different part of such 
principal amount.
SECTION 105.   NOTICES, ETC., TO TRUSTEE AND THE 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,
          (a)  the Trustee by any Holder or by the Company shall be 
sufficient for every purpose hereunder if made, given, furnished or filed in 
writing to or with the Trustee at its Corporate Trust Office, Attention: 
Corporate Trust & Agency Department, or
          (b)  the Company by the Trustee or by any Holder shall be 
sufficient for every purpose hereunder (unless otherwise herein expressly 
provided) if in writing and mailed, first-class postage prepaid, to the 
Company addressed to it at the address of its principal 
                                     -16-
office specified in the first paragraph of this instrument (Attention: Chief 
Financial Officer) 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 such Holder's 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.  Any notice when mailed to a Holder in the aforesaid manner shall be 
conclusively deemed to have been received by such Holder whether or not 
actually received by such Holder. 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 that 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 that 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.
                                     -17-
SECTION 109.   SUCCESSORS AND ASSIGNS.
          All covenants and agreements in this Indenture by the Company shall 
bind its successors and assigns, whether so expressed or not.
SECTION 110.   SEPARABILITY CLAUSE.
          In case any provision in this Indenture or in the Convertible 
Debentures 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 Convertible Debentures, express 
or implied, shall give to any Person, other than the parties hereto and their 
successors hereunder, the holders of Senior Indebtedness, the holders of 
Convertible Preferred Securities (to the extent provided herein) and the 
Holders of Convertible Debentures, any benefit or any legal or equitable 
right, remedy or claim under this Indenture.
SECTION 112.   GOVERNING LAW.
          THIS INDENTURE AND THE CONVERTIBLE DEBENTURES SHALL BE GOVERNED BY 
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT 
REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAWS.
SECTION 113.   LEGAL HOLIDAYS.
          In any case where any Interest Payment Date, Redemption Date or 
Stated Maturity of any Convertible Debenture or the last date on which a 
Holder has the right to convert his Convertible Debentures shall not be a 
Business Day, then (notwithstanding any other provision of this Indenture or 
of the Convertible Debentures) payment of interest or principal or conversion 
of the Convertible Debentures need not be made on such date, but may be made 
on the next succeeding Business Day (except that, if such Business Day is in 
the next succeeding calendar year, such Interest Payment Date, Redemption 
Date or Stated Maturity, as the case may be, shall be the immediately 
preceding Business Day) with the same force and effect as if made on the 
Interest Payment Date or Redemption Date, or at the Stated Maturity or on 
such last day for conversion, PROVIDED, that no interest shall accrue for 
                                     -18-

$355,670,131.25, except for Convertible Debentures authenticated and 
delivered upon registration of transfer of, or in exchange for, or in lieu 
of, other Convertible Debentures pursuant to Section 304, 305, 306, 906, 1109 
or 1301.
          The Convertible Debentures shall be known and designated as the "7% 
Convertible Junior Subordinated Debentures Due 2028" of the Company.  Their 
Stated Maturity shall be May 1, 2028, and they shall bear interest at the 
rate of 7% per annum, from May 4, 1998 or from the most recent Interest 
Payment Date to which interest has been paid or duly provided for, as the 
case may be, payable quarterly (subject to deferral as set forth herein), in 
arrears, on February 1, May 1, August 1 and November 1 (each an "Interest 
Payment Date") of each year, commencing August 1, 1998, until the principal 
thereof is paid or made available for payment, and they shall be paid to the 
Person in whose name the Convertible Debenture is registered at 5:00 p.m. 
(New York City time) on the regular record date for such interest 
installment, which shall be the close of business on the Business Day next 
preceding such interest payment date (the "Regular Record Date");  provided, 
however, in the event the Convertible Debentures are held by any entity other 
than the Trust, the Company may set other record dates.  Interest will 
compound quarterly and will accrue at the rate of 7% per annum on any 
interest installment in arrears for more than one quarter or during an 
extension of an interest payment period as set forth in Section 312 hereof.
          The amount of interest payable for any period will be computed on 
the basis of a 360-day year of twelve 30-day months. Except as provided in 
the following sentence, the amount of interest payable for any period shorter 
than a full quarterly period for which interest is computed, will be computed 
on the basis of the actual number of days elapsed per 90-day quarter.  In the 
event that any date on which interest is payable on the Convertible 
Debentures is not a Business Day, then payment of interest payable on such 
date will be made on the next succeeding day which is a Business Day (and 
without any interest or other payment in respect of any such delay), except 
that, if such Business Day is in the next succeeding calendar year, such 
payment shall be made on the immediately preceding Business Day, in each case 
with the same force and effect as if made on such date.
                                     -21-
          If at any time while the Property Trustee is the Holder of any 
Convertible Debentures, the Trust or the Property Trustee is required to pay 
any taxes, duties, assessments or governmental charges of whatever nature 
(other than withholding taxes) imposed by the United States, or any other 
taxing authority, then, in any such case, the Company will pay as additional 
interest ("Additional Interest") on the Convertible Debentures held by the 
Property Trustee, such amounts as shall be required so that the net amounts 
received and retained by the Trust and the Property Trustee after paying any 
such taxes, duties, assessments or other governmental charges will be not 
less than the amounts the Trust and the Property Trustee would have received 
had no such taxes, duties, assessments or other governmental charges been 
imposed.
          The principal of and interest on the Convertible Debentures shall 
be payable at the office or agency of the Company in the United States 
maintained for such purpose and at any other office or agency maintained by 
the Company for such purpose in such coin or currency of the United States of 
America as at the time of payment is legal tender for payment of public and 
private debts; PROVIDED, HOWEVER, that unless the Convertible Debentures are 
held by the Trust or any successor permissible under Section 612 of this 
Indenture, at the option of the Company payment of interest may be made by 
check mailed to the address of the Person entitled thereto as such address 
shall appear in the Security Register.
          The Convertible Debentures shall be redeemable as provided in 
Article Eleven hereof.
          The Convertible Debentures shall be subordinated in right of 
payment to Senior Indebtedness as provided in Article Twelve hereof.
          The Convertible Debentures shall be convertible as provided in 
Article Thirteen hereof.
SECTION 302.   DENOMINATIONS.
          The Convertible Debentures shall be issuable only in registered 
form without coupons.
                                     -22-
SECTION 303.   EXECUTION, AUTHENTICATION, DELIVERY AND DATING.
          The Convertible Debentures shall be executed on behalf of the 
Company by its Chairman of the Board, its Vice Chairman of the Board, its 
Chief Executive Officer, its President, its Chief Financial Officer,  or one 
of its Vice Presidents, and if the Company so chooses, under its corporate 
seal reproduced thereon attested by its Secretary or one of its Assistant 
Secretaries.  The signature of any of these officers on the Convertible 
Debentures may be manual or facsimile.
          Convertible Debentures 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 
Convertible Debentures or did not hold such offices at the date of such 
Convertible Debentures.
          At any time and from time to time after the execution and delivery 
of this Indenture, the Company may deliver Convertible Debentures executed by 
the Company to the Trustee for authentication, together with a Company Order 
for the authentication and delivery of such Convertible Debentures; and the 
Trustee in accordance with such Company Order shall authenticate and make 
available for delivery such Convertible Debentures as in this Indenture 
provided and not otherwise.
          The Convertible Debentures shall be dated the date of 
authentication.
          No Convertible Debenture shall be entitled to any benefit under 
this Indenture or be valid or obligatory for any purpose unless there appears 
on such Convertible Debenture a certificate of authentication substantially 
in the form provided for herein executed by the Trustee by manual signature, 
and such certificate upon any Convertible Debenture shall be conclusive 
evidence, and the only evidence, that such Convertible Debenture has been 
duly authenticated and delivered hereunder.
SECTION 304.   TEMPORARY CONVERTIBLE DEBENTURES.
          Pending the preparation of definitive Convertible Debentures, the 
Company may execute, and upon Company Order the Trustee shall authenticate 
and deliver, temporary Convertible Debentures which are typewritten, printed, 
lithographed or otherwise produced, in any authorized denomination, 
substantially of the tenor of the definitive Convertible Debentures in lieu 
of which they are issued and with such appropriate insertions, omissions, 
                                     -23-
substitutions and other variations as the officers executing such Convertible 
Debentures may determine, as evidenced by their execution of such Convertible 
Debentures.
          If temporary Convertible Debentures are issued, the Company will 
cause definitive Convertible Debentures to be prepared without unreasonable 
delay. After the preparation of definitive Convertible Debentures, the 
temporary Convertible Debentures shall be exchangeable for definitive 
Convertible Debentures upon surrender of the temporary Convertible Debentures 
at any office or agency of the Company designated pursuant to Section 1002, 
without charge to the Holder.  Upon surrender for cancellation of any one or 
more temporary Convertible Debentures the Company shall execute and the 
Trustee shall authenticate and make available for delivery in exchange 
therefor a like principal amount of definitive Convertible Debentures of 
authorized denominations.  Until so exchanged the temporary Convertible 
Debentures shall in all respects be entitled to the same benefits under this 
Indenture as definitive Convertible Debentures.
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 and in any 
other office or agency designated pursuant to Section 1002 being herein 
sometimes collectively 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 Convertible Debentures and of transfers of 
Convertible Debentures. The Trustee is hereby appointed "Security Registrar" 
for the purpose of registering Convertible Debentures and transfers of 
Convertible Debentures as herein provided.
          Upon surrender for registration of transfer of any Convertible 
Debenture at an office or agency of the Company designated pursuant to 
Section 1002 for such purpose, the Company shall execute, and the Trustee 
shall authenticate and deliver, in the name of the designated transferee or 
transferees, one or more new Convertible Debentures of any authorized 
denominations and of a like aggregate principal amount.
          At the option of the Holder, Convertible Debentures may be 
exchanged for other Convertible Debentures of any authorized denominations 
and of a like aggregate principal amount, upon surrender of the Convertible 
Debentures to be exchanged at such office or agency.  Whenever any 
Convertible Debentures are so surrendered for exchange, the Company shall 
execute, and the Trustee shall authenticate and make available for delivery, 
the Convertible Debentures which the Holder making the exchange is entitled 
to receive.
                                     -24-
          All Convertible Debentures issued upon any registration of transfer 
or exchange of Convertible Debentures shall be the valid obligations of the 
Company, evidencing the same debt, and entitled to the same benefits under 
this Indenture, as the Convertible Debentures surrendered upon such 
registration of transfer or exchange.
          Every Convertible Debenture presented or surrendered for 
registration of transfer or for exchange shall (if so required by the Company 
or the Trustee) be duly endorsed, or be accompanied by a written instrument 
of transfer in form satisfactory to the Company 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 Convertible Debentures, but the Company may require payment of a 
sum sufficient to cover any tax or other governmental charge that may be 
imposed in connection with any registration of transfer or exchange of 
Convertible Debentures, other than exchanges pursuant to Section 304, 906, 
1109 or 1301 not involving any transfer.
          The Company shall not be required (i) in the case of a partial 
redemption of the Securities, to issue, register the transfer of or exchange 
any Convertible Debenture during a period beginning at the opening of 
business 15 days before the day of the mailing of a notice of redemption of 
Convertible Debenture selected for redemption under the Section 1105 and 
ending at the close of business on the day of such mailing, or (ii) to 
register the transfer of or exchange any Convertible Debenture so selected 
for redemption in whole or in part, except the unredeemed portion of any 
Convertible Debenture being redeemed in part.
SECTION 306.   MUTILATED, DESTROYED, LOST AND STOLEN CONVERTIBLE DEBENTURES.
          If any mutilated Convertible Debenture is surrendered to the 
Trustee, the Company shall execute and the Trustee shall authenticate and 
deliver in exchange therefor a new Convertible Debenture of like tenor and 
principal amount and bearing a number not contemporaneously outstanding.
          If there shall be delivered to the Company and the Trustee (i) 
evidence to their satisfaction of the destruction, loss or theft of any 
Convertible Debenture and (ii) such Convertible Debenture 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 Convertible Debenture has been acquired by a bona fide purchaser, the 
Company shall execute and the Trustee shall authenticate and deliver, in lieu 
of any such
                                       -25-
destroyed, lost or stolen Convertible Debenture, a new Convertible Debenture 
of like tenor and principal amount and bearing a number not contemporaneously 
outstanding.
          In case any such mutilated, destroyed, lost or stolen Convertible 
Debenture has become or is about to become due and payable, the Company in 
its discretion may, instead of issuing a new Convertible Debenture, pay such 
Convertible Debenture.
          Upon the issuance of any new Convertible Debenture under this 
Section, the Company may require the payment of a sum sufficient to cover any 
tax or other governmental charge that may be imposed in relation thereto and 
any other expenses (including the fees and expenses of the Trustee) connected 
therewith.
          Every new Convertible Debenture issued pursuant to this Section in 
lieu of any destroyed, lost or stolen Convertible Debenture shall constitute 
an original additional contractual obligation of the Company, whether or not 
the destroyed, lost or stolen Convertible Debenture shall be at any time 
enforceable by anyone, and shall be entitled to all the benefits of this 
Indenture equally and proportionately with any and all other Convertible 
Debentures duly issued hereunder.
          The provisions of this Section are exclusive and shall preclude (to 
the extent lawful) all other rights and remedies with respect to the 
replacement or payment of mutilated, destroyed, lost or stolen Convertible 
Debentures.
SECTION 307.   PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.
          Interest on any Convertible Debenture which is payable, and is 
punctually paid or duly provided for, on any Interest Payment Date shall be 
paid to the Person in whose name that Convertible Debenture (or one or more 
Predecessor Securities) is registered at 5:00 p.m. (New York City time) on 
the Regular Record Date.
          Any interest on any Convertible Debenture which is payable, but is 
not punctually paid or duly provided for, on any Interest Payment Date 
(herein called "Defaulted Interest") shall forthwith cease to be payable to 
the Holder on the relevant Regular Record Date by virtue of having been such 
Holder, and such Defaulted Interest may be paid by the Company, at its 
election in each case, as provided in Clause (a) or (b) below:
          (a)  The Company may elect to make payment of any Defaulted 
Interest to the Persons in whose names the Convertible Debentures (or their 
respective Predecessor Securities) are registered at 5:00 p.m. (New York City 
time) on a Special Record Date for the
                                       -26-
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 Convertible Debenture and the 
date of the proposed payment, and at the same time the Company shall deposit 
with the Trustee an amount of money equal to the aggregate amount proposed to 
be paid in respect of such Defaulted Interest or shall make arrangements 
satisfactory to the Trustee for such deposit prior to the date of the 
proposed payment, such money when deposited to be held in trust for the 
benefit of the Persons entitled to such Defaulted Interest as in this Clause 
(a) provided.  Thereupon the Trustee shall fix a Special Record Date for the 
payment of such Defaulted Interest which shall be not more than 15 days and 
not less than 10 days prior to the date of the proposed payment and not less 
than 10 days after the receipt by the Trustee of the notice of the proposed 
payment.  The Trustee shall promptly notify the Company of such Special 
Record Date and, in the name and at the expense of the Company, shall cause 
notice of the proposed payment of such Defaulted Interest and the Special 
Record Date therefor to be mailed, first-class postage prepaid, to each 
Holder at his address as it appears in the Security Register, not less than 
10 days prior to such Special Record Date.  Notice of the proposed payment of 
such Defaulted Interest and the Special Record Date therefor having been so 
mailed, such Defaulted Interest shall be paid to the Persons in whose names 
the Convertible Debentures (or their respective Predecessor Securities) are 
registered at 5:00 p.m. (New York City time) on such Special Record Date and 
shall no longer be payable pursuant to the following Clause (b).
          (b)  The Company may make payment of any Defaulted Interest in any 
other lawful manner not inconsistent with the requirements of any securities 
exchange on which the Convertible Debentures may be listed, and, if so 
listed, 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 (B), such manner of payment shall be deemed practicable by the 
Trustee.
          Subject to the foregoing provisions of this Section 307, each 
Convertible Debenture delivered under this Indenture upon registration of 
transfer of or in exchange for or in lieu of any other Convertible Debenture 
shall carry the rights to interest accrued and unpaid, and to accrue 
(including in each such case Additional Payments, if any), which were carried 
by such other Convertible Debenture.
          In the case of any Convertible Debenture which is converted after 
any Regular Record Date and on or prior to the next succeeding Interest 
Payment Date (other than any Convertible Debenture whose Maturity is prior to 
such Interest Payment Date), interest whose Stated Maturity is on such 
Interest Payment Date shall be payable on such Interest Payment Date 
notwithstanding such conversion, and such interest (whether or not punctually 
                                       -27-
paid or duly provided for) shall be paid to the Person in whose name that 
Convertible Debenture (or one or more Predecessor Securities) is registered 
at 5:00 p.m. (New York City time) on such Regular Record Date.  Except as 
otherwise expressly provided in the immediately preceding sentence, in the 
case of any Convertible Debenture that is converted prior to any Regular 
Record Date, interest whose Stated Maturity is after the date of conversion 
of such Convertible Debenture shall not be payable, and the Company shall not 
make nor be required to make any other payment, adjustment or allowance with 
respect to accrued but unpaid interest (including Additional Payments, if 
any) on the Convertible Debentures being converted, which shall be deemed to 
be paid in full.  Subject to any right of the Holder of such Convertible 
Debenture or any Predecessor Security to receive interest as provided in this 
paragraph and the second paragraph of Clause (a) of Section 1302, the 
Company's delivery upon conversion of the fixed number of shares of Sun 
Common Stock into which the Convertible Debentures are convertible (together 
with the cash payment, if any, in lieu of fractional shares) shall be deemed 
to satisfy the Company's obligation to pay the principal amount at Maturity 
of the portion of Convertible Debentures so converted and any unpaid interest 
(including Additional Payments, if any) accrued on such Convertible 
Debentures at the time of such conversion.  If any Convertible Debenture 
called for redemption is converted, any money deposited with the Trustee or 
with any Paying Agent or so segregated and held in trust for the redemption 
of such Convertible Debenture shall (subject to any right of the Holder of 
such Convertible Debenture or any Predecessor Security to receive interest as 
provided in this paragraph) be paid to the Company upon Company Request or, 
if then held by the Company, shall be discharged from such trust.
SECTION 308.   PERSONS DEEMED OWNERS.
          Prior to due presentment of a Convertible Debenture for 
registration of transfer, the Company, the Trustee and any Agent of the 
Company or the Trustee may treat the Person in whose name such Convertible 
Debenture is registered as the owner of such Convertible Debenture for the 
purpose of receiving payment of principal of and (subject to Section 307) 
interest (including Additional Payments, if any) on such Convertible 
Debenture and for all other purposes whatsoever, whether or not such 
Convertible Debenture be overdue, and neither the Company, the Trustee nor 
any Agent of the Company or the Trustee shall be affected by notice to the 
contrary.
SECTION 309.   CANCELLATION.
          All Convertible Debentures surrendered for payment, redemption, 
registration of transfer or exchange or conversion shall, if surrendered to 
any Person other than the Trustee, be delivered to the Trustee and shall be 
promptly cancelled by it.  The Company 
                                       -28-
may at any time deliver to the Trustee for cancellation any Convertible 
Debentures previously authenticated and delivered hereunder which the Company 
may have acquired in any manner whatsoever, and all Convertible Debentures so 
delivered shall be promptly cancelled by the Trustee. No Convertible 
Debentures shall be authenticated in lieu of or in exchange for any 
Convertible Debentures cancelled as provided in this Section, except as 
expressly permitted by this Indenture.  All cancelled Convertible Debentures 
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 the 
certificates representing such cancelled Convertible Debentures.
SECTION 310.   RIGHT OF SET OFF.
          Notwithstanding anything to the contrary in this Indenture, the 
Company shall have the right to set off any payment it is otherwise required 
to make hereunder to the extent the Company has theretofore made, or is 
concurrently on the date of such payment making, a payment under the 
Guarantee.
SECTION 311.   CUSIP NUMBERS.
          The Company in issuing the Convertible Debentures 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 Convertible Debentures 
or as contained in any notice of a redemption and that reliance may be placed 
only on the other identification numbers printed on the Convertible 
Debentures, and any such redemption shall not be affected by any defect in or 
omission of such numbers.
SECTION 312.   OPTION TO EXTEND INTEREST PAYMENT PERIOD.
          (a)  So long as no Event of Default has occurred and is continuing, 
the Company shall have the right at any time during the term of the 
Convertible Debentures to defer interest payments (including Additional 
Payments) from time to time by extending the interest payment period for 
successive periods (each, an "Extension Period") not exceeding 20 consecutive 
quarters for each such period; PROVIDED that no Extension Period may extend 
beyond the maturity date of the Convertible Debentures.  At the end of each 
Extension Period, the Company shall pay all interest then accrued and unpaid 
(including Additional Interest and Liquidated Damages) together with interest 
thereon compounded quarterly at the rate specified for the Convertible 
Debentures to the extent permitted by applicable law ("Compounded Interest"); 
PROVIDED that during any Extension Period, the Company shall (i) 
                                       -29-
not declare or pay dividends on, or make a distribution with respect to, or 
redeem or purchase or acquire, or make a liquidation payment with respect to, 
any of its capital stock (other than (A) purchases or acquisitions of shares 
of Sun Common Stock in connection with the satisfaction by the Company of its 
obligations under any employee benefit plans or the satisfaction by the 
Company of its obligations pursuant to any contract or security requiring the 
Company to purchase shares of Sun Common Stock, (B) as a result of a 
reclassification of the Company's capital stock or the exchange or conversion 
of one class or series of the Company's capital stock for another class or 
series of the Company's capital stock or (C) the purchase of fractional 
interests in shares of the Company's capital stock pursuant to the conversion 
or exchange provisions of such capital stock or the security being converted 
or exchanged (or make any guarantee payments with respect to the foregoing), 
(ii) not make any payment of interest, principal or premium, if any, on or 
repay, repurchase or redeem any debt securities (including guarantees) issued 
by the Company that rank PARI PASSU with or junior to the Convertible 
Debentures (except by conversion into or exchange for shares of its capital 
stock) and (iii) not make any guarantee payments with respect to the 
foregoing (other than pursuant to the Guarantee).  Prior to the termination 
of any such Extension Period, the Company may further extend such Extension 
Period; PROVIDED that such Extension Period, together with all such previous 
and further extensions thereof, may not exceed 20 consecutive quarters or 
extend beyond the maturity date of the Convertible Debentures.  Upon the 
termination of any Extension Period and the payment of all amounts then due, 
the Company may commence a new Extension Period, subject to the above 
requirements.  No interest during an Extension Period, except at the end 
thereof, shall be due and payable.
          (b)  If the Property Trustee is the sole Holder of the Convertible 
Debentures at the time the Company selects an Extension Period, the Company 
shall give written notice to the Administrative Trustees and the Property 
Trustee of its selection of such Extension Period at least one Business Day 
prior to the earlier of (i) the date the distributions on the Convertible 
Preferred Securities are payable or (ii) if the Convertible Preferred 
Securities are listed on the New York Stock Exchange or other stock exchange 
or quotation system, the date the Trust is required to give notice to the New 
York Stock Exchange or other applicable self-regulatory organization or to 
holders of the Convertible Preferred Securities of the record date or the 
date such distributions are payable, but in any event not less than 10 
Business Days prior to such record date.  The Company shall cause the Trust 
to give notice of the Company's selection of such Extension Period to the 
holders of the Convertible Preferred Securities.
          (c)  If the Property Trustee is not the sole holder of the 
Convertible Debentures at the time the Company selects an Extension Period, 
the Company shall give the Holders of the Convertible Debentures and the 
Trustee written notice of its selection of such 
                                       -30-
Extension Period at least 10 Business Days prior to the earlier of (i) the 
next succeeding Interest Payment Date or (ii) if the Convertible Preferred 
Securities are listed on the New York Stock Exchange or other stock exchange 
or quotation system, the date the Company is required to give notice to the 
New York Stock Exchange or other applicable self-regulatory organization or 
to holders of the Convertible Debentures on the record or payment date of 
such related interest payment, but in any event not less than two Business 
Days prior to such record date.
          (d)  The quarter in which any notice is given pursuant to 
paragraphs (b) and (c) hereof shall be counted as one of the 20 quarters 
permitted in the maximum Extension Period permitted under paragraph (a) 
hereof.
SECTION 313.   PAYING AGENT, SECURITY REGISTRAR AND CONVERSION AGENT.
          The Trustee will initially act as Paying Agent, Security Registrar 
and Conversion Agent.  The Company may change any Paying Agent, Security 
Registrar, co-registrar or Conversion Agent without prior notice.  The 
Company or any of its Affiliates may act in any such capacity.  The Trustee 
is entitled to the protections of Article VI in its capacity as Paying Agent, 
Registrar and Conversion Agent.
SECTION 314.   GLOBAL SECURITY.
          (a)  In connection with a Dissolution Event,
               (1)  the Convertible Debentures in book-entry certificated 
form may be presented to the Trustee by the Property Trustee in exchange for 
a global Convertible Debenture in an aggregate principal amount equal to the 
aggregate principal amount of all outstanding Convertible Debentures (a 
"Global Security"), to be registered in the name of the Depositary, or its 
nominee, and delivered by the Trustee to the Depositary for crediting to the 
accounts of its participants pursuant to the instructions of the 
Administrative Trustees.  The Company upon any such presentation shall 
execute a Global Security in such aggregate principal amount and deliver the 
same to the Trustee for authentication and delivery in accordance with this 
Indenture.  Payments on the Convertible Debentures issued as a Global 
Security will be made to the Depositary; and
               (2)  if any Convertible Preferred Securities are held in non 
book-entry certificated form, the Convertible Debentures in certificated form 
may be presented to the Trustee by the Property Trustee and any Preferred 
Security Certificate which represents Convertible Preferred Securities other 
than Convertible Preferred Securities held by the
                                       -31-
Depositary or its nominee ("Non Book-Entry Preferred Securities") will be 
deemed to represent beneficial interests in Convertible Debentures presented 
to the Trustee by the Property Trustee having an aggregate principal amount 
equal to the aggregate liquidation amount of the Non Book-Entry Preferred 
Securities until such Preferred Security Certificates are presented to the 
Security Registrar for transfer or reissuance at which time such Convertible 
Preferred Security Certificates will be cancelled and a Convertible 
Debenture, registered in the name of the holder of the Convertible Preferred 
Security Certificate or the transferee of the holder of such Preferred 
Security Certificate, as the case may be, with an aggregate principal amount 
equal to the aggregate liquidation amount of the Convertible Preferred 
Security Certificate cancelled, will be executed by the Company and delivered 
to the Trustee for authentication and delivery in accordance with this 
Indenture.  On issue of such Convertible Debentures, Convertible Debentures 
with an equivalent aggregate principal amount that were presented by the 
Property Trustee to the Trustee will be deemed to have been cancelled.
          (b)  A Global Security may be transferred, in whole but not in 
part, only to another nominee of the Depositary, or to a nominee of such 
successor Depositary.
          (c)  If (i) the Depositary notifies the Company that it is 
unwilling or unable to continue as a depositary for such Global Security and 
no successor depositary shall have been appointed, (ii) the Depositary, at 
any time, ceases to be a clearing agency registered under the Exchange Act at 
which time the Depositary is required to be so registered to act as such 
depositary and no successor depositary shall have been appointed, (iii) the 
Company, in its sole discretion, determines that such Global Security shall 
be so exchangeable or (iv) there shall have occurred an Event of Default with 
respect to such Convertible Debentures, as the case may be, the Company will 
execute, and, subject to Article Three of this Indenture, the Trustee, upon 
written notice from the Company and receipt of a Company Order, will 
authenticate and deliver the Convertible Debentures in definitive registered 
form without coupons, in authorized denominations, and in an aggregate 
principal amount equal to the principal amount of the Global Security in 
exchange for such Global Security. In addition, upon an Event of Default or 
if the Company may at any time determine that the Convertible Debentures 
shall no longer be represented by a Global Security, in such event the 
Company will execute, and subject to Section 305 of this Indenture, the 
Trustee, upon receipt of an Officers' Certificate evidencing such 
determination by the Company, will authenticate and make available for 
delivery the Convertible Debentures in definitive registered form without 
coupons, in authorized denominations, and in an aggregate principal amount 
equal to the principal amount of the Global Security in exchange for such 
Global Security.  Upon the exchange of the Global Security for such 
Convertible Debentures in definitive registered form without coupons, in 
authorized denominations, the Global Security shall be cancelled

liquidation of the Trust upon the redemption of all of the outstanding 
Convertible Preferred Securities of the Trust or (ii) certain mergers, 
consolidations or amalgamations, each as permitted by the Declaration.
SECTION 502.   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.
          If an Event of Default occurs and is continuing, then and in every 
such case the Trustee or the Holders of not less than 25% in principal amount 
of the Outstanding Convertible Debentures may declare the principal of all 
the Convertible Debentures and any other amounts payable hereunder 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 
and all accrued interest shall become immediately due and payable.
          At any time after such a declaration of acceleration has been made 
and before a judgment or decree for payment of the money due has been 
obtained by the Trustee as provided in this Article, the Holders of a 
majority in aggregate principal amount of the Outstanding Convertible 
Debentures, by written notice to the Company and the Trustee, may rescind and 
annul such declaration and its consequences if:
          (a)  the Company has paid or deposited with the Trustee a sum 
sufficient to pay
               (i)  all overdue interest (including Additional Payments, if
     any) on all Convertible Debentures,
               (ii)  the principal of any Convertible Debentures which have
     become due otherwise than by such declaration of acceleration and
     interest thereon at the rate borne by the Convertible Debentures, and
                                       -37-
               (iii)  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
          (b)  all Events of Default, other than the non-payment of the
principal of Convertible Debentures 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:
          (a)  default is made in the payment of any interest (including 
Additional Interest and Compounded Interest, if any) on any Convertible 
Debenture when such interest becomes due and payable and such default 
continues for a period of 30 days, or
          (b)  default is made in the payment of the principal of any 
Convertible Debenture at the Maturity thereof,
the Company will, upon demand of the Trustee, pay to it, for the benefit of 
the Holders of such Convertible Debentures, the whole amount then due and 
payable on such Convertible Debentures for principal and interest (including 
Additional Interest and Compounded Interest, if any) and, to the extent that 
payment thereof shall be legally enforceable, interest on any overdue 
principal and on any overdue interest (including Additional Interest and 
Compounded Interest, if any), at the rate borne by the Convertible 
Debentures, and, in addition thereto, such further amount as shall be 
sufficient to cover the costs and expenses of collection, including the 
reasonable compensation, expenses, disbursements and advances of the Trustee, 
its agents and counsel.
           If an Event of Default occurs and is continuing, the Trustee may 
in its discretion proceed to protect and enforce its rights and the rights of 
the Holders by such appropriate judicial proceedings as the Trustee shall 
deem most effectual to protect and enforce any such rights, whether for the 
specific enforcement of any covenant or agreement 
                                       -38-
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 Convertible Debentures), 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 Convertible Debentures or the rights of any Holder thereof or to 
authorize the Trustee to vote in respect of the claim of any Holder in any 
such proceeding.
SECTION 505.   TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF CONVERTIBLE
               DEBENTURES.
          All rights of action and claims under this Indenture or the 
Convertible Debentures may be prosecuted and enforced by the Trustee without 
the possession of any of the Convertible Debentures 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 
Convertible Debentures in respect of which such judgment has been recovered.
                                       -39-
SECTION 506.   APPLICATION OF MONEY COLLECTED.
          Subject to Article Twelve, 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 interest (including Additional Payments, if any), 
upon presentation of the Convertible Debentures 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 all Senior Indebtedness of the
     Company to the extent required by Article Twelve;
          THIRD:    To the payment of the amounts then due and unpaid for
     principal of and interest (including Additional Payments, if any) on
     the Convertible Debentures 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
     Convertible Debentures for principal and interest (including
     Additional Payments, if any), respectively; and
          FOURTH:   To the payment of the remainder, if any, to the
     Company.
SECTION 507.   LIMITATION ON SUITS.
          Subject to Section 516, no Holder of any Convertible Debenture 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
          (a)  such Holder has previously given written notice to the Trustee of
a continuing Event of Default;
          (b)  if the Trust is not the sole holder of Convertible Debentures,
the Holders of not less than 25% in aggregate principal amount of the
Outstanding Convertible Debentures 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;
                                       -40-
          (c)  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;
          (d)  the Trustee for 60 days after its receipt of such notice, 
request and offer of indemnity has failed to institute any such proceeding; 
and
          (e)  no direction inconsistent with such written request has been 
given to the Trustee during such 60-day period by the Holders of a majority 
in principal amount of the Outstanding Convertible Debentures;
it being understood and intended that no one or more Holders shall have any 
right in any manner whatever by virtue of, or by availing of, any provision 
of this Indenture to affect, disturb or prejudice the rights of any other 
Holders, or to obtain or to seek to obtain priority or preference over any 
other Holders or to enforce any right under this Indenture, except in the 
manner herein provided and for the equal and ratable benefit of all the 
Holders.
SECTION 508.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL AND INTEREST
               AND CONVERT.
          Notwithstanding any other provision in this Indenture, the Holder 
of any Convertible Debenture shall have the right, which is absolute and 
unconditional, to receive payment of the principal of and (subject to Section 
307) interest (including Additional Payments, if any) on such Convertible 
Debenture on the respective Stated Maturities expressed in such Convertible 
Debenture (or, in the case of redemption, on the Redemption Date) and to 
convert such Convertible Debenture in accordance with Article Thirteen and to 
institute suit for the enforcement of any such payment and right to convert, 
and such rights shall not be impaired without the consent of such Holder.
SECTION 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.
                                       -41-
SECTION 510.   RIGHTS AND REMEDIES CUMULATIVE.
          Except as otherwise provided with respect to the replacement or 
payment of mutilated, destroyed, lost or stolen Convertible Debentures 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 
Convertible Debenture to exercise any right or remedy accruing upon any Event 
of Default shall impair any such right or remedy or constitute a waiver of 
any such Event of Default or an acquiescence therein.  Every right and remedy 
given by this Article or by law to the Trustee or to the 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 
Convertible Debentures shall have the right to direct the time, method and 
place of conducting any proceeding for any remedy available to the Trustee or 
exercising any trust or power conferred on the Trustee; PROVIDED, that
          (a)  such direction shall not be in conflict with any rule of law 
or with this Indenture; and
          (b)  the Trustee may take any other action deemed proper by the 
Trustee which is not inconsistent with such direction.
SECTION 513.   WAIVER OF PAST DEFAULTS.
          Subject to Sections 502 and 902 hereof, the Holders of not less 
than a majority in principal amount of the Outstanding Convertible Debentures 
may on behalf of the Holders of all the Convertible Debentures waive any past 
default hereunder and its consequences, except a default
                                     -42-
          (a)  in the payment of the principal of, premium, if any, or 
interest (including Additional Payments, if any) on any Convertible Debenture 
(unless such default has been cured and a sum sufficient to pay all matured 
installments of interest and principal due otherwise than by acceleration has 
been deposited with the Trustee); or
          (b)  in respect of a covenant or provision hereof that under 
Article Nine cannot be modified or amended without the consent of the Holder 
of each Outstanding Security affected; PROVIDED, HOWEVER, that if the 
Convertible Debentures are held by the Trust or a trustee of the Trust, such 
waiver shall not be effective until the holders of a majority in liquidation 
amount of Trust Securities shall have consented to such waiver; PROVIDED, 
FURTHER, that if the consent of the Holder of each outstanding Convertible 
Debenture is required, such waiver shall not be effective until each holder 
of the Trust Securities shall have consented to such waiver.
          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 or in any suit for the enforcement of the right to 
receive the principal of and interest (including Additional Payments, if any) 
on any Convertible Debenture or to convert any Convertible Debenture in 
accordance with Article Thirteen.
SECTION 515.   WAIVER OF STAY OR EXTENSION LAWS.
          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 stay or extension 
law wherever enacted, now or at any time hereafter in force, which may affect 
the covenants or the performance of this Indenture; and the Company (to the 
extent that it may lawfully do so) hereby expressly waives all benefit or 
                                     -43-
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 516.   ENFORCEMENT BY HOLDERS OF CONVERTIBLE PREFERRED SECURITIES.
          Notwithstanding the foregoing, if an Event of Default has occurred 
and is continuing and such event is attributable to the failure of the 
Company to pay interest or principal on the Convertible Debentures on the 
date such interest or principal is otherwise payable, the Company 
acknowledges that, in such event, a holder of Convertible Preferred 
Securities may institute a Direct Action for payment on or after the 
respective due date specified in the Convertible Debentures.  The Company may 
not amend this Indenture to remove the foregoing right to bring a Direct 
Action without the prior written consent of all the holders of Convertible 
Preferred Securities.  Notwithstanding any payment made to such holder of 
Convertible Preferred Securities by the Company in connection with a Direct 
Action, the Company shall remain obligated to pay the principal of and 
interest on the Convertible Debentures (including Additional Payments, if 
any) held by the Trust or the Property Trustee and the Company shall be 
subrogated to the rights of the holder of such Convertible Preferred 
Securities with respect to payments on the Convertible Preferred Securities 
to the extent of any payments made by the Company to such holder in any 
Direct Action.  The holders of Convertible Preferred Securities will not be 
able to exercise directly any other remedy available to the Holders of the 
Convertible Debentures.
                                  ARTICLE VI
                                  The Trustee
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 personal financial liability in the performance of any of its 
duties or in the exercise of any of its rights or powers, if it shall have 
reasonable grounds for believing that the repayment of such funds or 
liability is not reasonably assured to it under the terms of this Indenture 
or indemnity reasonably satisfactory to the Trustee 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

and has a combined capital and surplus of at least $25,000,000 as set forth 
in its most recent published annual report of conditions and has its 
Corporate Trust Office in New York, New York.  If such Person publishes

specified in this Article.
SECTION 610.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

          (b)  The Trustee may resign at any time by giving written notice 
thereof to the Company.  If an instrument of acceptance by a successor 
Trustee shall not have been delivered to the Trustee within 30 days after the 
giving of such notice of resignation, the resigning Trustee may petition any 
court of competent jurisdiction for the appointment of a successor Trustee.
          (c)  The Trustee may be removed at any time by Act of the Holders 
of a majority in principal amount of the Outstanding Convertible Debentures, 
delivered to the Trustee and to the Company.  If an instrument of acceptance 
by a successor Trustee shall not have been delivered to the Trustee within 30 
days after the giving of such notice of resignation, the resigning Trustee

                                     -48-
          (d)  If at any time:
               (i)  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 Convertible Debenture for at least six months,
     or
               (ii)  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
               (iii)  the Trustee shall become incapable of acting or shall
     be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
     its property shall be appointed or any public officer shall take
     charge or control of the Trustee or of its property or affairs for the
     purpose of rehabilitation, conservation or liquidation,
then, in any such case, (A) the Company by Board Resolution may remove the 
Trustee, or (B) subject to Section 514, any Holder who has been a bona fide 
Holder of a Convertible Debenture for at least six months may, on behalf of 
himself and all others similarly situated, petition any court of competent 
jurisdiction for the removal of the Trustee and the appointment of a 
successor Trustee.
          (e)  If the Trustee shall resign, be removed or become incapable of 
acting, or if a vacancy shall occur in the office of Trustee for any cause, 
the Company, by a Board Resolution, shall promptly appoint a successor 
Trustee.  If, within one year after such resignation, removal or 
incapability, or the occurrence of such vacancy, a successor Trustee shall be 
appointed by Act of the Holders of a majority in principal amount of the 
Outstanding Convertible Debentures delivered to the Company and the retiring 
Trustee, the successor Trustee so appointed shall, forthwith upon its 
acceptance of such appointment, become the successor Trustee and supersede 
the successor Trustee appointed by the Company.  If no successor Trustee 
shall have been so appointed by the Company or the Holders and accepted 
appointment in the manner hereinafter provided, any Holder who has been a 
bona fide Holder of a Convertible Debenture for at least six months may, on 
behalf of himself and all others similarly situated, petition any court of 
competent jurisdiction for the appointment of a successor Trustee.
          (f)  The Company shall give notice of each resignation and each 
removal of the Trustee and each appointment of a successor Trustee to all 
Holders in the manner 
                                     -49-

SECTION 611.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.
          Every successor Trustee appointed hereunder shall execute, 
acknowledge and deliver to the Company and to the retiring Trustee an 
instrument accepting such appointment, and thereupon the resignation or 
removal of the retiring Trustee shall become effective and such successor 
Trustee, without any further act, deed or conveyance, shall become vested 
with all the rights, powers, trusts and duties of the retiring Trustee; 
PROVIDED, that on 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.  Upon request of any such successor Trustee, the Company shall 
execute any and all instruments required to more fully and certainly vest in 
and confirm to such successor Trustee all such rights, powers and trusts.
          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 Convertible Debentures 
shall have been authenticated, but not delivered, by the Trustee then in 
office, any successor by merger, conversion or consolidation to such 
authenticating Trustee may adopt such authentication and deliver the 
Convertible Debentures so authenticated with the same effect as if such 
successor Trustee had itself authenticated such Convertible Debentures.
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 Convertible Debentures), the Trustee 
shall be subject to the provisions 
                                     -50-
of the Trust Indenture Act regarding the collection of claims against the 
Company (or any such other obligor).

not constitute constructive notice of any information contained therein or

compliance with any of its covenants hereunder (as to which the Trustee is 
entitled to rely exclusively on Officers' Certificates).
          The Company shall also provide to the Trustee on a timely basis

indenture supplemental hereto.  If a record date is fixed, the Holders on 
such record date, or their duly designated proxies, and only such Persons, 
shall be entitled to consent to such supplemental indenture, whether or not 
such Holders remain Holders after such record date; PROVIDED that unless such 
consent shall have become effective by virtue of the requisite percentage 
having been obtained prior to the date which is 90 days after such record 
date, any such consent previously given shall automatically and without 
further action by any Holder be cancelled and of no further effect.
SECTION 903.   EXECUTION OF SUPPLEMENTAL INDENTURES.

interest on the Convertible Debentures and Additional Payments, if any, in 
accordance with the terms of the Convertible Debentures and this Indenture.
SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.
          The Company will maintain in the United States an office or agency 
where Convertible
                                     -57-
Debentures may be presented or surrendered for payment, where Convertible 
Debentures may be surrendered for registration of transfer or exchange and 
where notices and demands to or upon the Company in respect of the 
Convertible Debentures and this Indenture may be served.  The Company will 
give prompt written notice to the Trustee of the location, and any change in

the Trustee with the address thereof, such presentations, surrenders, notices 
and demands may be made or served at the Corporate Trust Office of the 
Trustee, 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 (in the United States) where the Convertible Debentures 
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 the United States 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 CONVERTIBLE DEBENTURE PAYMENTS TO BE HELD 
               IN TRUST.
          If the Company shall at any time act as its own Paying Agent, it 
will, on or before each due date of the principal of or interest on any of 
the Convertible Debentures, segregate and hold in trust for the benefit of 
the Persons entitled thereto a sum sufficient to pay the principal or 
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, it will, 
prior to each due date of the principal of or interest on any Convertible 
Debentures, 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 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 (i) comply with the provisions of the Trust Indenture 
Act applicable to it as a Paying Agent and (ii) during the continuance of any 
default by the Company (or any other obligor upon the Convertible Debentures) 
in the making of any payment in respect of the Convertible Debentures, upon
                                     -58-
the written request of the Trustee, forthwith pay to the Trustee all sums 
held in trust by such Paying Agent as such.
          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 interest 
on (including Additional Payments, if any) any Convertible Debenture and 
remaining unclaimed for two years after such principal or interest has become 
due and payable shall be paid to the Company on Company Request, or (if then 
held by the Company) shall be discharged from such trust; and the Holder of 
any such Convertible Debenture 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.
SECTION 1004.  STATEMENT BY OFFICERS AS TO DEFAULT.

end of each fiscal year of the Company ending after the date hereof, an

cured or waived or otherwise has ceased to exist, no payment (by set-off or 
otherwise) may be made by or on behalf of the Company which is an obligor 
under such Designated Senior Indebtedness on account of the principal of, 
premium, if any, or interest on the Convertible Debentures (including any 
repurchases of any of the Convertible Debentures), or on account of the 
redemption provisions of the Convertible Debentures, in any such case, other 
than payments made with Junior Convertible Debentures or from a Defeasance 
Trust.  Notwithstanding the foregoing, unless the Designated Senior 
Indebtedness in respect of which such event of default exists has been 
declared due and payable in its entirety within 179 days after the Payment 
Notice is delivered as set forth above (the "PAYMENT BLOCKAGE PERIOD") (and 
such declaration has not been rescinded or waived), at the end of the Payment 
Blockage Period, the Company shall be required to pay all sums not paid to 
the Holders of the Convertible Debentures during the Payment Blockage Period 
due to the foregoing prohibitions and to resume all other payments as and 
when due on the Convertible Debentures.  Any number of Payment Notices may be 
given; PROVIDED that (i) not more than one Payment Notice shall be given 
within a period of any 360 consecutive days, and (ii) no default that existed 
upon the date of such Payment Notice or the commencement of such Payment 
Blockage Period (whether or not such event of default is on the same issue of 
Senior Indebtedness) shall be made the basis for the commencement of any 
other Payment Blockage Period unless such other Payment Blockage Period is 
commenced by a Payment Notice from the Representative under the Credit 
Agreement and such event of default shall have been cured or waived for a 
period of at least 90 consecutive days. 
          (c)  Upon any distribution of assets of the Company upon any 
dissolution, winding up, total or partial liquidation or reorganization of 
the Company, whether voluntary or involuntary, in bankruptcy, insolvency, 
receivership or a similar proceeding or upon assignment for the benefit of 
creditors or any marshalling of assets or liabilities, the provisions of 
Section 1203 of this Indenture shall apply.
          The subordination provisions hereof shall continue to be effective 
or be reinstated, as the case may be, if at any time any payment of any 
Senior Indebtedness is rescinded or must otherwise be returned by any holder 
of such Senior Indebtedness upon the insolvency, bankruptcy or reorganization 
of the Company or otherwise, all as though such payment has not been made.
                                    -68-
SECTION 1203.  LIQUIDATION; DISSOLUTION; BANKRUPTCY.
          Upon any distribution of assets of the Company or upon any 
dissolution, winding up, total or partial liquidation or reorganization of 
the Company, whether voluntary or involuntary, in bankruptcy, insolvency, 
receivership or a similar proceeding or upon assignment for the benefit of 
creditors or any marshalling of assets or liabilities:
          (a)  the holders of all Senior Indebtedness of the Company, will 
first be entitled to receive payment in full in cash or Cash Equivalents (or 
have such payment duly provided for to the satisfaction of such holders) or 
otherwise to the extent holders accept satisfaction of amounts due by 
settlement in other than cash or Cash Equivalents before the Holders are 
entitled to receive any payment on account of the principal of, premium, if 
any, and interest on the Convertible Debentures or any Obligation in respect 
of the Convertible Debentures (other than Junior Convertible Debentures or 
from a Defeasance Trust);
          (b)  any payment or distribution of assets of the Company of any 
kind or character from any source, whether in cash, property or securities 
(other than Junior Convertible Debentures or from a Defeasance Trust) to 
which the Holders or the Trustee on behalf of the Holders would be entitled 
(by set-off or otherwise), except for the provisions of this Article Twelve, 
shall be paid by the liquidating trustee or Agent or other person making such 
a payment or distribution directly to the holders of such Senior Indebtedness 
or their representative to the extent necessary to make payment in full (or 
have such payment duly provided for) on all such Senior Indebtedness 
remaining unpaid, after giving effect to any concurrent payment or 
distribution to the holders of such Senior Indebtedness; and
          (c)  in the event that, notwithstanding the foregoing, any payment 
or distribution of assets of the Company (other than Junior Convertible 
Debentures or from a Defeasance Trust) shall be received by the Trustee or 
the Holders at a time when such payment or distribution is prohibited by the 
foregoing provisions, such payment or distribution shall be held in trust for 
the benefit of the holders of such Senior Indebtedness, and shall be paid or 
delivered by the Trustee or such Holders, as the case may be, to the holders 
of such Senior Indebtedness remaining unpaid or unprovided for or to their 
representative or representatives, or to the trustee or trustees under any 
indenture pursuant to which any instruments evidencing any of such Senior 
Indebtedness may have been issued, ratably according to the aggregate 
principal amounts remaining unpaid on account of such Senior Indebtedness 
held or represented by each, for application to the payment of all such 
Senior Indebtedness remaining unpaid, to the extent necessary to pay all such 
Senior Indebtedness in full in cash or Cash Equivalents or otherwise to the 
extent holders accept 
                                     -69-
satisfaction of amounts due by settlement in other than cash or Cash 
Equivalents after giving effect to any concurrent payment or distribution to 
the holders of such Senior Indebtedness.
SECTION 1204.  SUBROGATION.
          Subject to the payment in full in cash or Cash Equivalents of all 
Senior Indebtedness of the Company as provided herein, the Holders of 
Convertible Debentures shall be subrogated to the rights of the holders of 
such Senior Indebtedness to receive payments or distributions of assets of 
the Company applicable to the Senior Indebtedness until all amounts owing on 
the Convertible Debentures shall be paid in full, and for the purpose of such 
subrogation no such payments or distributions to the holders of such Senior 
Indebtedness by or on behalf of the Company, or by or on behalf of the 
Holders by virtue of this Article Twelve, which otherwise would have been 
made to the Holders shall, as between the Company and the Holders, be deemed 
to be payment by the Company or on account of such Senior Indebtedness, it 
being understood that the provisions of this Article Twelve are and are 
intended solely for the purpose of defining the relative rights of the 
Holders, on the one hand, and the holders of such Senior Indebtedness, on the 
other hand.
          If any payment or distribution to which the Holders would otherwise 
have been entitled but for the provisions of this Article Twelve shall have 
been applied, pursuant to the provisions of this Article Twelve, to the 
payment of amounts payable under Senior Indebtedness of the Company, then the 
Holders shall be entitled to receive from the holders of such Senior 
Indebtedness any payments or distributions received by such holders of Senior 
Indebtedness in excess of the amount sufficient to pay all amounts payable 
under or in respect of such Senior Indebtedness in full in cash or Cash 
Equivalents.
SECTION 1205.  TRUSTEE TO EFFECTUATE SUBORDINATION.
          Each Holder of Convertible Debentures by such Holder's acceptance 
thereof authorizes and directs the Trustee on such Holder's behalf to take 
such action as may be necessary or appropriate to effectuate the 
subordination provided in this Article Twelve and appoints the Trustee as 
such Holder's attorney-in-fact for any and all such purposes.
SECTION 1206.  NOTICE BY THE COMPANY.
          The Company shall give prompt written notice to a Responsible 
Officer of the Trustee of any fact known to the Company which would prohibit 
the making of any payment of monies to or by the Trustee in respect of the 
Convertible Debentures pursuant to the
                                     -70-
provisions of this Article Twelve.  Notwithstanding the provisions of this 
Article Twelve or any other provision of this Indenture, the Trustee shall 
not be charged with knowledge of the existence of any facts which would 
prohibit the making of any payment of monies to or by the Trustee in respect 
of the Convertible Debentures pursuant to the provision of this Article 
Twelve, unless and until a Responsible Officer of the Trustee shall have 
received written notice thereof at the Corporate Trust Office of the Trustee 
from the Company or a holder or holders of Senior Indebtedness or from any 
trustee therefor; and before the receipt of any such written notice, the 
Trustee, subject to the provisions of Section 603 hereof, shall be entitled 
in all respects to assume that no such facts exist; PROVIDED, HOWEVER, that 
if the Trustee shall not have received the notice provided for in this 
Section 1206 at least two Business Days prior to the date upon which by the 
terms hereof any money may become payable for any purpose (including, without 
limitation, the payment of the principal of (and premium, if any) or interest 
(including Additional Payments, if any) on any Convertible Debenture), then, 
anything herein contained to the contrary notwithstanding, the Trustee shall 
have full power and authority to receive such money and to apply the same to 
the purposes for which they were received, and shall not be affected by any 
notice to the contrary which may be received by it within two Business Days 
prior to such date.
          The Trustee, subject to the provisions of Section 603, shall be 
entitled to rely on the delivery to it of a written notice by a Person 
representing himself to be a holder of Senior Indebtedness (or a trustee on 
behalf of such holder) to establish that such notice has been given by a 
holder of such Senior Indebtedness or a trustee on behalf of any such holder 
or holders.  In the event that the Trustee determines in good faith that 
further evidence is required with respect to the right of any Person as a 
holder of Senior Indebtedness to participate in any payment or distribution 
pursuant to this Article Twelve, the Trustee may request such Person to 
furnish evidence to the reasonable satisfaction of the Trustee as to the 
amount of Senior Indebtedness held by such Person, the extent to which such 
Person is entitled to participate in such payment or distribution and any 
other facts pertinent to the right of such Person under this Article Twelve, 
and, if such evidence is not furnished, the Trustee may defer any payment to 
such Person pending judicial determination as to the right of such Person to 
receive such payment.
SECTION 1207.  RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.
          The Trustee in its individual capacity shall be entitled to all the 
rights set forth in this Article Twelve in respect of any Senior Indebtedness 
at any time held by it, to the same extent as any other holder of Senior 
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any 
of its rights as such holder.
                                     -71-
          With respect to the holders of Senior Indebtedness of the Company, 
the Trustee undertakes to perform or to observe only such of its covenants 
and obligations as are set forth in this Article Twelve, and no implied 
covenants or obligations with respect to the holders of such Senior 
Indebtedness shall be read into this Indenture against the Trustee.  The 
Trustee shall not be deemed to owe any fiduciary duty to the holders of such 
Senior Indebtedness and, subject to the provisions of Section 603, the 
Trustee shall not be liable to any holder of such Senior Indebtedness if it 
shall pay over or deliver to Holders of Convertible Debentures, the Company 
or any other Person money or assets to which any holder of such Senior 
Indebtedness shall be entitled by virtue of this Article Twelve or otherwise. 
With respect to the holders of Senior Indebtedness, the Trustee undertakes to 
perform or to observe only such of its covenants or obligations as are 
specifically set forth in this Article Twelve and no implied covenants or 
obligations with respect to holders of Senior Indebtedness shall be read into 
this Indenture against the Trustee.
SECTION 1208.  SUBORDINATION MAY NOT BE IMPAIRED.
          No right of any present or future holder of any Senior Indebtedness 
to enforce subordination as herein provided shall at any time in any way be 
prejudiced or impaired by any act or failure to act on the part of the 
Company or by any act or failure to act, in good faith, by any such holder, 
or by any noncompliance by the Company with the terms, provisions and 
covenants of this Indenture, regardless of any knowledge thereof which any 
such holder may have or otherwise be charged with.
          Without in any way limiting the generality of the foregoing 
paragraph, the holders of Senior Indebtedness may, at any time and from time 
to time, without the consent of or notice to the Trustee or the Holders of 
the Convertible Debentures, without incurring responsibility to the holders 
of the Convertible Debentures and without impairing or releasing the 
subordination provided in this Article Twelve or the obligations hereunder of 
the Holders of the Convertible Debentures to the holders of Senior 
Indebtedness, do any one or more of the following:  (i) change the manner, 
place or terms of payment or extend the time of payment of, or renew or 
alter, such Senior Indebtedness, or otherwise amend or supplement in any 
manner such Senior Indebtedness or any instrument evidencing the same or any 
agreement under which such Senior Indebtedness is outstanding; (ii) sell, 
exchange, release or otherwise deal with any property pledged, mortgaged or 
otherwise securing such Senior Indebtedness; (iii) release any Person liable 
in any manner for the collection of such Senior Indebtedness; and (iv) 
exercise or refrain from exercising any rights against the Company and any 
other Person.
                                     -72-
                                  ARTICLE XIII
                      Conversion of Convertible Debentures
SECTION 1301.  CONVERSION RIGHTS.
          Subject to and upon compliance with the provisions of this Article, 
the Convertible Debentures are convertible, at the option of the Holder, at 
any time after June 28, 1998 and on or prior to 5:00 p.m. (New York City 
time) on the Business Day immediately preceding the date of repayment of such 
Convertible Debentures, whether at maturity or upon redemption (either at the 
option of the Company or pursuant to a Tax Event), into fully paid and 
nonassessable shares of Sun Common Stock of the Company at an initial 
conversion rate of 1.2419 shares of Sun Common Stock for each $25 in 
aggregate principal amount of Convertible Debentures (equal to a conversion 
price of $20.13 per share of Sun Common Stock), subject to adjustment as 
described in this Article Thirteen.  A Holder of Convertible Debentures may 
convert any portion of the principal amount of the Convertible Debentures 
into that number of fully paid and nonassessable shares of Sun Common Stock 
(calculated as to each conversion to the nearest 1/100th of a share) obtained 
by dividing the principal amount of the Convertible Debentures to be 
converted by such conversion price.  In case a Convertible Debenture or 
portion thereof is called for redemption, such conversion right in respect of 
the Convertible Debenture or portion so called shall expire at 5:00 p.m. (New 
York City time) on the Business Day immediately preceding the corresponding 
Redemption Date, unless the Company defaults in making the payment due upon 
redemption.
SECTION 1302.  CONVERSION PROCEDURES.
          (a)  In order to convert all or a portion of the Convertible 
Debentures, the Holder thereof shall deliver to the Conversion Agent an 
irrevocable Notice of Conversion setting forth the principal amount of 
Convertible Debentures to be converted, together with the name or names, if 
other than the Holder, in which the shares of Sun Common Stock should be 
issued upon conversion and, if such Convertible Debentures are definitive 
Convertible Debentures, surrender to the Conversion Agent the Convertible 
Debentures to be converted, duly endorsed or assigned to the Company or in 
blank.  In addition, a holder of Convertible Preferred Securities may 
exercise its right under the Declaration to convert such Convertible 
Preferred Securities into Sun Common Stock by delivering to the Conversion 
Agent an irrevocable Notice of Conversion setting forth the information 
called for by the preceding sentence and directing the Conversion Agent (i) 
to exchange such Convertible Preferred Security for a portion of the 
Convertible Debentures held by the Trust 
                                     -73-
(at an exchange rate of $25 liquidation amount of Convertible Debentures for 
each Convertible Preferred Security) and (ii) to immediately convert such 
Convertible Debentures, on behalf of such holder, into Sun Common Stock of 
the Company pursuant to this Article Thirteen and, if such Convertible 
Preferred Securities are in definitive form, surrendering such Convertible 
Preferred Securities, duly endorsed or assigned to the Company or in blank.  
So long as any Convertible Preferred Securities are outstanding, the Trust 
shall not convert any Convertible Debentures except pursuant to a Notice of 
Conversion delivered to the Conversion Agent by a holder of Convertible 
Preferred Securities.
          If a Notice of Conversion is delivered on or after the Regular 
Record Date and prior to the subsequent Interest Payment Date, the Holder 
will be entitled to receive the interest payable on the subsequent Interest 
Payment Date on the portion of Convertible Debentures to be converted 
notwithstanding the conversion thereof prior to such Interest Payment Date.  
Except as otherwise provided in the immediately preceding sentence, in the 
case of any Convertible Debenture which is converted, interest whose Stated 
Maturity is after the date of conversion of such Convertible Debenture shall 
not be payable, and the Company shall not make nor be required to make any 
other payment, adjustment or allowance with respect to accrued but unpaid 
interest (including Additional Payments, if any) on the Convertible 
Debentures being converted, which shall be deemed to be paid in full.  If any 
Convertible Debenture called for redemption is converted, any money deposited 
with the Trustee or with any Paying Agent or so segregated and held in trust 
for the redemption of such Convertible Debenture shall (subject to any right 
of the Holder of such Convertible Debenture or any Predecessor Security to 
receive interest as provided in the last paragraph of Section 307 and this 
paragraph) be paid to the Company upon Company Request or, if then held by 
the Company, shall be discharged from such trust.
          Each conversion shall be deemed to have been effected immediately 
prior to 5:00 p.m. (New York City time) on the day on which the Notice of 
Conversion was received (the "Conversion Date") by the Conversion Agent from 
the Holder or from a holder of the Convertible Preferred Securities effecting 
a conversion thereof pursuant to its conversion rights under the Declaration, 
as the case may be.  The Person or Persons entitled to receive the Sun Common 
Stock issuable upon such conversion shall be treated for all purposes as the 
record holder or holders of such Sun Common Stock as of the Conversion Date.  
As promptly as practicable on or after the Conversion Date, the Company shall 
issue and deliver at the office of the Conversion Agent, unless otherwise 
directed by the Holder in the Notice of Conversion, a certificate or 
certificates for the number of full shares of Sun Common Stock issuable upon 
such conversion, together with the cash payment, if any, in lieu of any 
fraction of any share to the Person or Persons entitled to receive the same.  
The Conversion Agent shall deliver such certificate or certificates to such 
Person or Persons.
                                     -74-
          (b)  Subject to any right of the Holder of such Convertible 
Debenture or any Predecessor Security to receive interest as provided in the 
last paragraph of Section 307 and the second paragraph of Clause (a) of 
Section 1302, the Company's delivery upon conversion of the fixed number of 
shares of Sun Common Stock into which the Convertible Debentures are 
convertible (together with the cash payment, if any, in lieu of fractional 
shares) shall be deemed to satisfy the Company's obligation to pay the 
principal amount at Maturity of the portion of Convertible Debentures so 
converted and any unpaid interest (including Additional Payments, if any) 
accrued on such Convertible Debentures at the time of such conversion.
          (c)  No fractional shares of Sun Common Stock will be issued as a 
result of conversion, but in lieu thereof, the Company shall pay to the 
Conversion Agent a cash adjustment in an amount equal to the same fraction of 
the last reported sale price of such fractional interest on the date on which 
the Convertible Debentures or Convertible Preferred Securities, as the case 
may be, were duly surrendered to the Conversion Agent for conversion, or, if 
such day is not a Trading Day, on the next Trading Day, and the Conversion 
Agent in turn will make such payment, if any, to the Holder of the 
Convertible Debentures or the holder of the Convertible Preferred Securities 
so converted.
          (d)  In the event of the conversion of any Convertible Debenture in 
part only, a new Convertible Debenture or Convertible Debentures for the 
unconverted portion thereof will be issued in the name of the Holder thereof 
upon the cancellation thereof in accordance with Section 305.
          (e)  In effecting the conversion transactions described in this 
Section, the Conversion Agent is acting as Agent of the holders of 
Convertible Preferred Securities (in the exchange of Convertible Preferred 
Securities for Convertible Debentures) and as Agent of the Holders of 
Convertible Debentures (in the conversion of Convertible Debentures into Sun 
Common Stock), as the case may be, directing it to effect such conversion 
transactions.  The Conversion Agent is hereby authorized (i) to exchange 
Convertible Debentures held by the Trust from time to time for Convertible 
Preferred Securities in connection with the conversion of such Convertible 
Preferred Securities in accordance with this Article Thirteen and (ii) to 
convert all or a portion of the Convertible Debentures into Sun Common Stock 
and thereupon to deliver such shares of Sun Common Stock in accordance with 
the provisions of this Article Thirteen and to deliver to the Trust a new 
Convertible Debenture or Convertible Debentures for any resulting unconverted 
principal amount.
          (f)  Except as provided in Section 202, all shares of Sun Common 
Stock delivered upon any conversion of Restricted Securities shall bear a 
Restrictive Securities Legend substantially in the form of the legend 
required to be set forth on such Convertible 
                                     -75-
Debentures and shall be subject to the restrictions on transfer provided in 
such legend and in Section 314 hereof.  Neither the Trustee nor the 
Conversion Agent shall have any responsibility for the inclusion or content 
of any such Restrictive Securities Legend on such Sun Common Stock; PROVIDED, 
HOWEVER, that the Trustee or the Conversion Agent shall have provided to the 
Company or to the Company's transfer Agent for such Sun Common Stock, prior 
to or concurrently with a request to the Company to deliver to such 
Conversion Agent certificates for such Sun Common Stock, written notice that 
the Convertible Debentures delivered for conversion are Restricted Securities.
SECTION 1303.  CONVERSION PRICE ADJUSTMENTS.
          The conversion price shall be subject to adjustment (without 
duplication) from time to time as follows:
          (a)  In case the Company shall, while any of the Convertible 
Debentures are outstanding, (i) pay a dividend or make a distribution with 
respect to its Sun Common Stock in shares of Sun Common Stock, (ii) subdivide 
its outstanding shares of Sun Common Stock, (iii) combine its outstanding 
shares of Sun Common Stock into a smaller number of shares or (iv) issue by 
reclassification of its shares of Sun Common Stock any shares of capital 
stock of the Company, the conversion price in effect immediately prior to 
such action shall be adjusted so that the Holder of any Convertible 
Debentures thereafter surrendered for conversion shall be entitled to receive 
the number of shares of capital stock of the Company which he would have 
owned immediately following such action had such Convertible Debentures been 
converted immediately prior thereto.  An adjustment made pursuant to this 
Section 1303(a) shall become effective immediately after the record date in 
the case of a dividend or other distribution and shall become effective 
immediately after the effective date in case of a subdivision, combination or 
reclassification (or immediately after the record date if a record date shall 
have been established for such event).  If, as a result of an adjustment made 
pursuant to this Section 1303(a), the Holder of any Convertible Debenture 
thereafter surrendered for conversion shall become entitled to receive shares 
of two or more classes or series of capital stock of the Company, the Board 
of Directors (whose determination shall be conclusive and shall be described 
in a Board Resolution filed with the Trustee) shall determine the allocation 
of the adjusted conversion price between or among shares of such classes or 
series of capital stock.
          (b)  In case the Company shall, while any of the Convertible 
Debentures are outstanding, issue rights or warrants to all holders of its 
Sun Common Stock entitling them (for a period expiring within 45 days after 
the record date mentioned in this Section 1303(b)) to subscribe for or 
purchase shares of Sun Common Stock at a price per share less than the 
                                     -76-
current market price per share of Sun Common Stock (as determined pursuant to 
1303(f) below) on such record date, the conversion price for the Convertible 
Debentures shall be adjusted so that the same shall equal the price 
determined by multiplying the conversion price in effect immediately prior to 
the date of issuance of such rights or warrants by a fraction of which the 
numerator shall be the number of shares of Sun Common Stock outstanding on 
the date of issuance of such rights or warrants plus the number of shares 
which the aggregate offering price of the total number of shares so offered 
for subscription or purchase would purchase at such current market price, and 
of which the denominator shall be the number of shares of Sun Common Stock 
outstanding on the date of issuance of such rights or warrants plus the 
number of additional shares of Sun Common Stock offered for subscription or 
purchase.  Such adjustment shall become effective immediately after the 
record date for the determination of stockholders entitled to receive such 
rights or warrants.  For the purposes of this subsection, the number of 
shares of Sun Common Stock at any time outstanding shall not include shares 
held in the treasury of the Company.  The Company shall not issue any rights 
or warrants in respect of shares of Sun Common Stock held in the treasury of 
the Company.  In case any rights or warrants referred to in this subsection 
in respect of which an adjustment shall have been made shall expire 
unexercised within 45 days after the same shall have been distributed or 
issued by the Company, the conversion price shall be readjusted at the time 
of such expiration to the conversion price that would have been in effect if 
no adjustment had been made on account of the distribution or issuance of 
such expired rights or warrants.  In determining whether any rights, options 
or warrants entitle the holder to subscribe for or purchase Sun Common Stock 
at less than the Current Market Price,  and in determining the aggregate 
offering price of such shares of Sun Common Stock, there shall be taken into 
account any consideration received for such rights, options or warrants, the 
value of such consideration, if other than cash, to be determined by the 
Board of Directors.  Notwithstanding this Article XIII, no adjustment will 
be made pursuant to this Article if the Company makes proper provision for 
each Holder of Convertible Preferred Securities who converts a Convertible 
Preferred Security to receive, in addition to the Sun Common Stock issuable 
upon such conversion, the kind and amount of assets (including securities) if 
such Holder had been a holder of the Common Stock at the time of the 
distribution of such assets or securities.  Rights, options or warrants 
distributed by the Company to all holders of the Sun Common Stock that 
entitle the holders thereof to purchase shares of the Company's capital stock 
and that, until the occurrence of an event (a "Triggering Event"), (i) are 
deemed to be transferred with the Sun Common Stock, (ii) are not exercisable 
and (iii) are also issued in respect of future issuances of Sun Common Stock, 
shall not be deemed to be distributed until the occurrence of the Triggering 
Event.
          (c)  Subject to the last sentence of this Section 1303(c), in case 
the Company shall, by dividend or otherwise, distribute to all holders of its 
Sun Common Stock evidences 
                                     -77-
of its indebtedness, shares of any class or series of capital stock, cash or 
assets (including securities, but excluding any rights or warrants referred 
to in Section 1303(b) and dividends and distributions in connection with the 
liquidation, dissolution or winding up of the Company and dividends and 
distributions paid exclusively in cash and any dividend or distribution 
referred to in Section 1303(a)), the conversion price shall be reduced so 
that the same shall equal the price determined by multiplying the conversion 
price in effect immediately prior to the effectiveness of the conversion 
price reduction contemplated by this Section 1303(c) by a fraction of which 
the numerator shall be the current market price per share (determined as 
provided in Section 1303(f)) of Sun Common Stock on the date fixed for the 
payment of such distribution (the "Reference Date") less the fair market 
value (as determined in good faith by the Board of Directors, whose 
determination shall be conclusive and described in a resolution of the Board 
of Directors), on the Reference Date, of the portion of the evidences of 
indebtedness, shares of capital stock, cash and assets so distributed 
applicable to one share of Sun Common Stock and the denominator shall be such 
current market price per share of the Sun Common Stock, such reduction to 
become effective immediately prior to the opening of business on the day 
following the Reference Date.  In the event that such dividend or 
distribution is not so paid or made, the conversion price shall again be 
adjusted to be the conversion price which would then be in effect if such 
dividend or distribution had not occurred.  If the Board of Directors 
determines the fair market value of any distribution for purposes of this 
Section 1303(c) by reference to the actual or when issued trading market for 
any securities comprising such distribution, it must in doing so consider the 
prices in such market over the same period used in computing the current 
market price per share of Sun Common Stock (determined as provided in Section 
1303(f)).  For purposes of this Section 1303(c), any dividend or distribution 
that includes shares of Sun Common Stock or rights or warrants to subscribe 
for or purchase shares of Sun Common Stock shall be deemed instead to be (1) 
a dividend or distribution of the evidences of indebtedness, shares of 
capital stock, cash or assets other than such shares of Sun Common Stock or 
such rights or warrants (making any conversion price reduction required by 
this Section 1303(c)) immediately followed by (2) a dividend or distribution 
of such shares of Sun Common Stock or such rights or warrants (making any 
further conversion price reduction required by Section 1303(a) or 1303(b)), 
except (A) the Reference Date of such dividend or distribution as defined in 
this 1303(c) shall be substituted as (a) "the record date in the case of a 
dividend or other distribution," and (b) "the record date for the 
determination of stockholders entitled to receive such rights or warrants" 
and (c) "the date fixed for such determination" within the meaning of 
Sections 1303(a) and 1303(b) and (B) any shares of Sun Common Stock included 
in such dividend or distribution shall not be deemed outstanding for purposes 
of computing any adjustment of the conversion price in Section 1303(a).
                                     -78-
          (d)  In case the Company shall pay or make a dividend or other 
distribution on its Sun Common Stock exclusively in cash (excluding any cash 
portion of distributions referred to in Section 1303(c) or in connection with 
a consolidation, merger or sale of assets of the Company as referred to in 
Section 1304(c)), excluding cash dividends if such dividends (and other 
distributions) together with all other such all-cash dividends and 
distributions made within the preceding 12 months in respect of which no 
adjustment has been made do not exceed 20% of the Company's current 
capitalization (being the product of the then current market price per share 
determined as provided in Section 1303(f) of Sun Common Stock times the 
number of shares of Sun Common Stock then outstanding) on the Trading Day 
immediately preceding the date of declaration of such dividend, the 
conversion price shall be reduced so that the same shall equal the price 
determined by multiplying the conversion price in effect immediately prior to 
the effectiveness of the conversion price reduction contemplated by this 
Section 1303(d) by a fraction of which the numerator shall be the current 
market price per share (determined as provided in Section 1303(f)) of the Sun 
Common Stock on the date fixed for the payment of such distribution less the 
amount of cash so distributed and not excluded as provided applicable to one 
share of Sun Common Stock and the denominator shall be such current market 
price per share of the Sun Common Stock, such reduction to become effective 
immediately prior to the opening of business on the day following the date 
fixed for the payment of such distribution; PROVIDED, HOWEVER, that in the 
event the portion of the cash so distributed applicable to one share of Sun 
Common Stock is equal to or greater than the current market price per share 
(as defined in Section 1303(f)) of the Sun Common Stock on the record date 
mentioned above, in lieu of the foregoing adjustment, adequate provision 
shall be made so that each Holder of Convertible Debentures shall have the 
right to receive upon conversion the amount of cash such Holder would have 
received had such Holder converted each Convertible Debenture immediately 
prior to the record date for the distribution of the cash.  In the event that 
such dividend or distribution is not so paid or made, the conversion price 
shall again be adjusted to be the conversion price which would then be in 
effect if such record date had not been fixed.
          (e)  In case a tender or exchange offer (other than an odd-lot 
offer) made by the Company or any Subsidiary of the Company for all or any 
portion of the Sun Common Stock shall expire and such tender or exchange 
offer shall involve the payment by the Company or such Subsidiary of 
consideration per share of Sun Common Stock having a fair market value (as 
determined in good faith by the Board of Directors, whose determination shall 
be conclusive and described in a resolution of the Board of Directors) at the 
last time (the "Expiration Time") tenders or exchanges may be made pursuant 
to such tender or exchange offer (as it shall have been amended) that exceeds 
110% of the current market price per share (determined as provided in Section 
1303(f)) of the Sun Common Stock on the Trading Day next succeeding the 
Expiration Time, the conversion price shall be reduced so 
                                     -79-
that the same shall equal the price determined by multiplying the conversion 
price in effect immediately prior to the effectiveness of the conversion 
price reduction contemplated by this Section 1303(e) by a fraction of which 
the numerator shall be the number of shares of Sun Common Stock outstanding 
(including any tendered or exchanged shares) at the Expiration Time 
multiplied by the current market price per share (determined as provided in 
Section 1303(f)) of the Sun Common Stock on the Trading Day next succeeding 
the Expiration Time and the denominator shall be the sum of (x) the fair 
market value (determined as aforesaid) of the aggregate consideration payable 
to stockholders based on the acceptance (up to any maximum specified in the 
terms of the tender or exchange offer) of all shares validly tendered or 
exchanged and not withdrawn as of the Expiration Time (the shares deemed so 
accepted, up to any such maximum, being referred to as the "Purchased 
Shares") and (y) the product of the number of shares of Sun Common Stock 
outstanding (less any Purchased Shares) at the Expiration Time and the 
current market price per share (determined as provided in Section 1303(f)) of 
the Sun Common Stock on the Trading Day next succeeding the Expiration Time, 
such reduction to become effective immediately prior to the opening of 
business on the day following the Expiration Time.
          (f)  For the purpose of any computation under Section 1303(b), 
1303(c), 1303(d) or 1303(e), the current market price per share of Sun Common 
Stock on any date in question shall be deemed to be the average of the daily 
Closing Prices for the five consecutive Trading Days selected by the Company 
commencing not more than 20 Trading Days before, and ending not later than, 
the earlier of the day in question or, if applicable, the day before the "ex" 
date with respect to the issuance or distribution requiring such computation; 
PROVIDED, HOWEVER, that if another event occurs that would require an 
adjustment pursuant to Section 1303(a) through (e), inclusive, the Board of 
Directors may make such adjustments to the Closing Prices during such five 
Trading Day period as it deems appropriate to effectuate the intent of the 
adjustments in this Section 1303, in which case any such determination by the 
Board of Directors shall be set forth in a Board Resolution and shall be 
conclusive.  For purposes of this paragraph, the term "ex" date, (i) when 
used with respect to any issuance or distribution, means the first date on 
which the Sun Common Stock trades regular way on the New York Stock Exchange 
or on such successor securities exchange as the Sun Common Stock may be 
listed or in the relevant market from which the Closing Prices were obtained 
without the right to receive such issuance or distribution, and (ii) when 
used with respect to any tender or exchange offer, means the first date on 
which the Sun Common Stock trades regular way on such securities exchange or 
in such market after the Expiration Time of such offer.
          (g)  The Company may make such reductions in the conversion price, in
addition to those required by Sections 1303 (a) through (e), as it considers to
be advisable to 
                                     -80-
avoid or diminish any income tax to holders of Sun Common Stock or rights to 
purchase Sun Common Stock resulting from any dividend or distribution of 
stock (or rights to acquire stock) or from any event treated as such for 
income tax purposes.  The Company from time to time may reduce the conversion 
price by any amount for any period of time if the period is at least 20 days, 
the reduction is irrevocable during the period, and the Board of Directors of 
the Company shall have made a determination that such reduction would be in 
the best interest of the Company, which determination shall be conclusive.  
Whenever the conversion price is reduced pursuant to the preceding sentence, 
the Company shall mail to holders of record of the Convertible Debentures a 
notice of the reduction at least 15 days prior to the date the reduced 
conversion price takes effect, and such notice shall state the reduced 
conversion price and the period it will be in effect.
          (h)  No adjustment in the conversion price shall be required unless 
such adjustment would require an increase or decrease of at least 1% in the 
conversion price; PROVIDED, HOWEVER, that any adjustments which by reason of 
this Section 1303(h) are not required to be made shall be carried forward and 
taken into account in determining whether any subsequent adjustment shall be 
required.
          (i)  If any action would require adjustment of the conversion price 
pursuant to more than one of the provisions described above, only one 
adjustment shall be made and such adjustment shall be the amount of 
adjustment that has the highest absolute value to the Holder of the 
Convertible Debentures.
          (j) Except as stated above, the conversion price will not be 
adjusted for the issuance of Sun Common Stock or any securities convertible 
into or exchangeable into Sun Common Stock or carrying the right to purchase 
any of the foregoing.
SECTION 1304.  FUNDAMENTAL CHANGE.
          (a)  In the event that the Company is party to any transaction
(including, without limitation, a merger other than a merger that does not
result in a reclassification, conversion, exchange or cancellation of Sun Common
Stock), consolidation, sale of all or substantially all of the assets of the
Company, recapitalization or reclassification of Sun Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination of Sun Common Stock) or
any compulsory share exchange (each of the foregoing being referred to as a
"Transaction"), in each case, as a result of which shares of Sun Common Stock
shall be converted into the right to receive, or shall be exchanged for, (i) in
the case of any Transaction other than a Transaction involving a Common Stock
Fundamental Change (and 
                                     -81-
subject to funds being legally available for such purpose under applicable 
law at the time of such conversion), securities, cash or other property, each 
Convertible Preferred Security shall thereafter be convertible into the kind 
and, in the case of a Transaction which does not involve a Fundamental 
Change, amount of securities, cash and other property receivable upon the 
consummation of such Transaction by a holder of that number of shares of Sun 
Common Stock into which a Convertible Preferred Security was convertible 
immediately prior to such Transaction, or (ii) in the case of a Transaction 
involving a Common Stock Fundamental Change, common stock, each Convertible 
Preferred Security shall thereafter be convertible (in the manner described 
therein) into common stock of the kind received by holders of Sun Common 
Stock (but in each case after giving effect to any adjustment discussed below 
relating to a Fundamental Change if such Transaction constitutes a 
Fundamental Change).  The holders of Convertible Preferred Securities will 
have no voting rights with respect to any Transaction.
          (b)  If any Fundamental Change occurs, then the conversion price in 
effect will be adjusted immediately after such Fundamental Change as 
described below.  In addition, in the event of a Common Stock Fundamental 
Change, each Convertible Preferred Security shall be convertible solely into 
common stock of the kind received by holders of Sun Common Stock as a result 
of such Common Stock Fundamental Change.
          (c)  The conversion price in the case of any Transaction involving 
a Fundamental Change will be adjusted immediately after such Fundamental 
Change:
               (i)  in the case of a Non-Stock Fundamental Change, the
          conversion price of the Convertible Preferred Securities will
          thereupon become the lower of (A) the conversion price in effect
          immediately prior to such Non-Stock Fundamental Change, but after
          giving effect to any other prior adjustments effected pursuant to the
          preceding paragraphs, and (B) the greater of the Applicable Price or
          the then applicable Reference Market Price plus any then-accrued and
          unpaid distributions on one Convertible Preferred Security; and 
               (ii)  in the case of a Common Stock Fundamental Change, the
          conversion price of the Convertible Preferred Securities in effect
          immediately prior to such Common Stock Fundamental Change, but after
          giving effect to any other prior adjustments effected pursuant to the
          preceding paragraphs, will thereupon be adjusted by multiplying such
          conversion price by a fraction of which the numerator will be the
          Purchaser Stock Price and the denominator will be the Applicable
          Price; provided, however, that in the event of a Common Stock
          Fundamental Change in which (A) 100% of the value of the 
                                     -82-
          consideration received by a holder of Sun Common Stock is common 
          stock of the successor, acquirer, or other third party (and cash, 
          if any, is paid only with respect to any fractional interests in 
          such common stock resulting from such Common Stock Fundamental 
          Change) and (B) all Sun Common Stock will be have been exchanged 
          for, converted into, or acquired for common stock (and cash with 
          respect to fractional interests) of the successor, acquirer, or 
          other third party, the conversion price of the Convertible 
          Preferred Securities in effect immediately prior to such Common 
          Stock Fundamental Change will thereupon be adjusted by multiplying 
          such conversion price by a fraction of which the numerator will be 
          one and the denominator will be the number of shares of common 
          stock of  the successor, acquirer, or other third party received by 
          a holder of one share of Sun Common Stock as a result of such 
          Common Stock Fundamental Change.
          The Company or the Person formed by such consolidation or resulting
from such merger or which acquired such assets or which acquires the Company's
shares, as the case may be, shall make provision in its certificate or articles
of incorporation or other constituent document to establish such right.  Such
certificate or articles of incorporation or other constituent document shall
provide for adjustments which, for events subsequent to the effective date of
such certificate or articles of incorporation or other constituent document,
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article Thirteen.  The above provisions shall similarly apply to
successive transactions of the foregoing type.
SECTION 1305.  NOTICE OF ADJUSTMENTS OF CONVERSION PRICE.
          Whenever the conversion price is adjusted as herein provided:
          (a)  the Company shall compute the adjusted Conversion Price and shall
prepare a certificate signed by the Chief Financial Officer or the Treasurer of
the Company setting forth the adjusted Conversion Price and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed with the Trustee, the Conversion Agent and
the transfer Agent for the Convertible Preferred Securities and the Convertible
Debentures; and
          (b)  a notice stating the Conversion Price has been adjusted and
setting forth the adjusted Conversion Price shall as soon as practicable be
mailed by the Company to all record holders of Convertible Preferred Securities
and the Convertible Debentures at their last addresses as they appear upon the
stock transfer books of the Company and the Trust.
                                     -83-
SECTION 1306.  PRIOR NOTICE OF CERTAIN EVENTS.
          In case:
          (a)  the Company shall (i) declare any dividend (or any other
distribution) on its Sun Common Stock, other than (A) a dividend payable in
shares of Sun Common Stock or (B) a dividend payable in cash that would not
require an adjustment pursuant to Section 1303(c) or 1303(d), or (ii) authorize
a tender or exchange offer that would require an adjustment pursuant to Section
1303(e);
          (b)  the Company shall authorize the granting to all holders of Sun
Common Stock of rights or warrants to subscribe for or purchase any shares of
stock of any class or series or of any other rights or warrants;

value), or of any consolidation or merger to which the Company is a party and
for which approval of any stockholders of the Company shall be required, or of
the sale or transfer of all or substantially all of the assets of the Company or
of any compulsory share exchange whereby the Sun Common Stock is converted into
other securities, cash or other property; or
          (d) of the voluntary or involuntary dissolution, liquidation or
winding up of the Company;
then the Company shall (1) if any Convertible Preferred Securities are

warrants or, if a record is not to be taken, the date as of which the holders of
Sun Common Stock of record to be entitled to such dividend, distribution, rights
or warrants are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up is expected to become effective, and the date as of which it is
expected that holders of Sun Common Stock of record shall be entitled to
exchange their shares of Sun Common Stock for securities, cash 
                                     -84-
or other property deliverable upon such reclassification, consolidation, 
merger, sale, transfer, share exchange, dissolution, liquidation or winding 
up (but no failure to mail such notice or any defect therein or in the 
mailing thereof shall affect the validity of the corporate action required to 
be specified in such notice).
SECTION 1307.  CERTAIN DEFINED TERMS.
          The following definitions shall apply to terms used in this Article
Thirteen:
          (a)  "CLOSING PRICE" of any Sun Common Stock on any day shall mean 
the reported last sale price on such day or in case no sale takes place on 
such day, the average of the reported closing bid and asked prices in each 
case on the New York Stock Exchange Consolidated Transactions Tape or, if the 
stock is not listed or admitted to trading on the New York Stock Exchange, on 
the principal national securities exchange on which such stock is listed or 
admitted to trading or, if not listed or admitted to trading on any national

          Notwithstanding the foregoing provisions, the issuance of any 
shares of Sun Common Stock pursuant to any plan providing for the 
reinvestment of dividends or interest payable on securities of the Company 
and the investment of additional optional amounts in shares of Sun Common 
Stock under any such plan, and the issuance of any shares of Sun Common Stock 
or options or rights to purchase such shares pursuant to any employee benefit 
plan or program of the Company or pursuant to any option, warrant, right or 
exercisable, exchangeable or convertible security outstanding as of the date 
the Convertible Debentures were first issued, shall not be deemed to 
constitute an issuance of Sun Common Stock or exercisable, exchangeable or 
convertible securities by the Company to which any of the adjustment 
provisions described above applies.  There shall also be no adjustment of the 
conversion price in case of the issuance of any stock (or securities 
convertible into or exchangeable for stock) of the Company except as 
specifically described in this Article Thirteen.
                                     -85-
SECTION 1309.  CERTAIN ADDITIONAL RIGHTS.
          In case the Company shall, by dividend or otherwise, declare or 
make a distribution on its Sun Common Stock referred to in Section 1303(c) or 
1303(d) (including, without limitation, dividends or distributions referred 
to in the last sentence of Section 1303(c)), the Holder of the Convertible 
Debentures, upon the conversion thereof subsequent to 5:00 p.m. (New York 
City time) on the date fixed for the determination of stockholders entitled 
to receive such distribution and prior to the effectiveness of the conversion 
price adjustment in respect of such distribution, shall also be entitled to 
receive for each share of Sun Common Stock into which the Convertible 
Debentures are converted, the portion of the shares of Sun Common Stock, 
rights, warrants, evidences of indebtedness, shares of capital stock, cash 
and assets so distributed applicable to one share of Sun Common Stock; 
PROVIDED, HOWEVER, that, at the election of the Company (whose election shall 
be evidenced by a resolution of the Board of Directors) with respect to all 
Holders so converting, the Company may, in lieu of distributing to such 
Holder any portion of such distribution not consisting of cash or securities 
of the Company, pay such Holder an amount in cash equal to the fair market 
value thereof (as determined in good faith by the Board of Directors, whose 
determination shall be conclusive and described in a resolution of the Board 
of Directors).  If any conversion of Convertible Debentures described in the 
immediately preceding sentence occurs prior to the payment date for a 
distribution to holders of Sun Common Stock which the Holder of Convertible 
Debentures so converted is entitled to receive in accordance with the 
immediately preceding sentence, the Company may elect (such election to be 
evidenced by a resolution of the Board of Directors) to distribute to such 
Holder a due ▇▇▇▇ for the shares of Sun Common Stock, rights, warrants, 
evidences of indebtedness, shares of capital stock, cash or assets to which 
such Holder is so entitled, PROVIDED, that such due ▇▇▇▇ (i) meets any 
applicable requirements of the principal national securities exchange or 
other market on which the Sun Common Stock is then traded and (ii) requires 
payment or delivery of such shares of Sun Common Stock, rights, warrants, 
evidences of indebtedness, shares of capital stock, cash or assets no later 
than the date of payment or delivery thereof to holders of shares of Sun 
Common Stock receiving such distribution.
SECTION 1310.  RESTRICTIONS ON SUN COMMON STOCK ISSUABLE UPON CONVERSION.
          (a)  Shares of Sun Common Stock to be issued upon conversion of a 
Convertible Debenture in respect of Restricted Convertible Preferred 
Securities shall bear the following legend (the "Restricted Common Stock 
Legend") unless the Company determines otherwise in accordance with 
applicable law.
                                     -86-
     THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE 
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE 
SECURITIES LAWS.  NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION 
HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR 
OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH 
TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS 
OF THE SECURITIES ACT.  THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF 
AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE 
WHICH IS AFTER THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES 
THEREOF UNDER RULE 144(k) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR RULE) 
(THE "RESALE RESTRICTION TERMINATION DATE") ONLY (A) TO SUN HEALTHCARE GROUP, 
INC. (THE "COMPANY") (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT 
UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL "ACCREDITED INVESTOR" 
WITHIN THE MEANING OF SUBPARAGRAPH (a)(1), (2), (3) OR (7) OF RULE 501 UNDER 
THE SECURITIES ACT THAT IS ACQUIRING THE SECURITY FOR ITS OWN ACCOUNT, OR FOR 
THE ACCOUNT OF SUCH AN INSTITUTIONAL "ACCREDITED INVESTOR," FOR INVESTMENT 
PURPOSES AND NOT WITH A VIEW TO, OR FOR OFFER OR SALE IN CONNECTION WITH, ANY 
DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT, OR (D) PURSUANT TO ANOTHER 
AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, 
SUBJECT TO THE COMPANY'S AND THE TRANSFER AGENT'S RIGHT PRIOR TO ANY SUCH 
OFFER, SALE OR TRANSFER (i) PURSUANT TO CLAUSES (C) OR (D) TO REQUIRE THE 
DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION 
SATISFACTORY TO EACH OF THEM, AND (ii) IN EACH OF THE FOREGOING CASES TO 
REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THIS SECURITY 
IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRANSFER AGENT.  THIS 
LEGEND WILL BE REMOVED UPON THE REQUEST OF A HOLDER AFTER THE RESALE 
RESTRICTION TERMINATION DATE.
          (b)  If shares of Sun Common Stock to be issued upon conversion of 
a Convertible Debenture in respect of Restricted Convertible Preferred 
Securities are to be registered in a name other than that of the Holder of 
such Convertible Preferred Security, then the Person in whose name such 
shares of Sun Common Stock are to be registered must deliver to the 
Conversion Agent a certificate satisfactory to the Company and signed by such 
Person, as to compliance with the restrictions on transfer applicable to such 
Convertible Preferred Security. Neither the Trustee nor any Conversion Agent 
or Registrar shall be
                                     -87-
required to register in a name other than that of the Holder shares of Sun 
Common Stock issued upon conversion of any such Convertible Debenture in 
respect of such Convertible Preferred Securities not so accompanied by a 
properly completed certificate.
SECTION 1311.  TRUSTEE NOT RESPONSIBLE FOR DETERMINING CONVERSION PRICE OR
               ADJUSTMENTS.
          Neither the Trustee nor any Conversion Agent shall at any time be 
under any duty or responsibility to any Holder of any Convertible Debenture 
to determine whether any facts exist which may require any adjustment of the 
conversion price, or with respect to the nature or extent of any such 
adjustment when made, or with respect to the method employed, or herein or in 
any supplemental indenture provided to be employed, in making the same.  
Neither the Trustee nor any Conversion Agent shall be accountable with 
respect to the validity or value (or the kind of account) of any shares of 
Sun Common Stock or of any securities or property, which may at any time be 
issued or delivered upon the conversion of any Convertible Debenture; and 
neither the Trustee nor any Conversion Agent makes any representation with 
respect thereto.  Neither the Trustee nor any Conversion Agent shall be 
responsible for any failure of the Company to make any cash payment or to 
issue, transfer or deliver any shares of Sun Common Stock or stock 
certificates or other securities or property upon the surrender of any 
Convertible Debenture for the purpose of conversion, or, except as expressly 
herein provided, to comply with any of the covenants of the Company contained 
in Article Ten or this Article Thirteen.
                                  ARTICLE XIV

                             Officers and Directors
SECTION 1401.  NO RECOURSE.
          No recourse under or upon any obligation, covenant or agreement of 
this Indenture, or of any Convertible Debenture, or for any claim based 
thereon or otherwise in respect thereof, shall be had against any 
incorporator, stockholder, officer or director, past, present or future as 
such, of the Company or of any predecessor or successor corporation, either 
directly or through the Company or any such predecessor or successor 
corporation, whether by virtue of any constitution, statute or rule of law, 
or by the enforcement of any assessment or penalty or otherwise; it being 
expressly understood that this Indenture and the obligations issued hereunder 
are solely corporate obligations, and that no such personal liability 
whatever shall attach to, or is or shall be incurred by, the incorporators, 
stockholders,

                  [FORM OF REVERSE OF CONVERTIBLE DEBENTURE]
          This Convertible Debenture is one of a duly authorized issue of 
securities of the Company designated as its 7% Convertible Junior 
Subordinated Debenture Due 2028   (herein called the "Convertible 
Debentures"), in aggregate principal amount of $355,670,131.25, issued and to 
be issued under an Indenture, dated as of May 4, 1998 (herein called the 
"Indenture"), between the Company and The Bank of New York, as Trustee 
(herein called the "Trustee", which term includes any successor trustee under 
the Indenture), to which Indenture and all indentures supplemental thereto 
reference is hereby made for a statement of the respective rights, 
limitations of rights, duties and immunities thereunder of the Trustee, the 
Company and the Holders of the Convertible Debentures, and of the terms upon 
which the Convertible Debentures are, and are to be, authenticated and 
delivered.  The terms of the Convertible Debentures include those stated in 
the Indenture and those made part of the Indenture by the Trust Indenture Act 
of 1939 (15 U.S.C. Sections  77aaa-77bbbb) ("TIA") as in effect on the date 
of the Indenture.  The Convertible Debentures are subject to, and qualified 
by, all such terms, certain of which are summarized hereon, and holders are 
referred to the Indenture and the TIA for a statement of such terms. No 
reference herein to the Indenture and no provision of this Convertible 
Debenture or of the Indenture shall alter or impair the obligation of the 
Company, which is absolute and unconditional, to pay the principal of and 
interest on this Convertible Debenture at the times, place and rate, and in 
the coin or currency, herein prescribed or to convert this Convertible 
Debenture as provided in the Indenture.  All terms used in this Convertible 
Debenture which are defined in the Indenture shall have the meanings assigned 
to them in the Indenture.  The Company will furnish to any Holder upon 
written request and without charge a copy of the Indenture.
          (1)  INTEREST.  The Convertible Debentures shall bear interest at 
the rate of 7% per annum, from May 4, 1998 or from the most recent Interest 
Payment Date to which interest has been paid or duly provided for, as the 
case may be, payable quarterly (subject to deferral as set forth herein), in 
arrears, on February 1, May 1, August 1 and November 1 (each an "Interest 
Payment Date") of each year, commencing August 1, 1998, until the principal 
thereof is paid or made available for payment, and they shall be paid to the 
Person in whose name the Convertible Debenture is registered at 5:00 p.m. 
(New York City time) on the regular record date for such interest 
installment, which shall be the close of business on the Business Day next 
preceding such Interest Payment Date (provided that the Company has not set a 
new record date pursuant to the Indenture) (the "Regular Record Date").  
Interest will compound quarterly and will accrue at the rate of 7% per annum 
on any interest installment in arrears for more than one quarter or during an 
extension of an interest payment period as set forth below.
                                     -7-
          The amount of interest payable for any period will be computed on 
the basis of a 360-day year of twelve 30-day months.  Except as provided in 
the following sentence, the amount of interest payable for any period shorter 
than a full quarterly period for which interest in computed, will be computed 
on the basis of the actual number of days elapsed per 90-day quarter.  In the 
event that any date on which interest is payable on the Convertible 
Debentures is not a Business Day, then payment of interest payable on such 
date will be made on the next succeeding day which is a Business Day (and 
without any interest or other payment in respect of any such delay), except 
that, if such Business Day is in the next succeeding calendar year, such 
payment shall be made on the immediately preceding Business Day, in each case 
with the same force and effect as if made on such date.
          If at any time while the Property Trustee is the Holder of any 
Convertible Debentures, the Trust or the Property Trustee is required to pay 
any taxes, duties, assessments or governmental charges of whatever nature 
(other than withholding taxes) imposed by the United States, or any other 
taxing authority, then, in any such case, the Company shall pay as additional 
interest ("Additional Interest") on the Convertible Debentures held by the 
Property Trustee, such amounts as shall be required so that the net amounts 
received and retained by the Trust and the Property Trustee after paying any 
such taxes, duties, assessments or other governmental charges will be not 
less than the amounts the Trust and the Property Trustee would have received 
had no such taxes, duties, assessments or other governmental charges been 
imposed.
          The principal of and interest on the Convertible Debentures shall 
be payable [insert, if global security is issued to the Depositary Trust 
Company or its nominee] [insert, if securities in definitive form are issued 
at the corporate office of the Indenture Trustee in the City of New York or 
at the office or agency of the Paying Agent in the United States maintained 
for such purpose] in such coin or currency of the United States of America 
as at the time of payment is legal tender for payment of public and private 
debts; PROVIDED, HOWEVER, that at the option of the Company payment of 
interest may be made by (i) check mailed to the address of the Person 
entitled thereto as such address shall appear in the Security Register, or 
(ii) by wire transfer to an account maintained by the Person entitled thereto 
as specified in the Securities Register, provided that proper transfer 
instructions have been received by the Regular Record Date.
          (2)  OPTION TO EXTEND INTEREST PAYMENT PERIOD.  The Company shall 
have the right at any time during the term of the Convertible Debentures to 
defer interest payments (including Additional Payments) from time to time by 
extending the interest payment period for successive periods (each, an 
"Extension Period") not exceeding 20 consecutive quarters for each such 
period; PROVIDED, no Extension Period may extend beyond the maturity date of 
the 
                                     -8-
Convertible Debentures.  At the end of each Extension Period, the Company 
shall pay all interest then accrued and unpaid (including Additional 
Interest) together with interest thereon compounded quarterly at the rate 
specified for the Convertible Debentures to the extent permitted by 
applicable law ("Compounded Interest"); PROVIDED, that during any Extension 
Period, the Company shall (i) not declare or pay dividends on, or make a 
distribution with respect to, or redeem or purchase or acquire, or make a 
liquidation payment with respect to, any of its capital stock (other than (A) 
purchases or acquisitions of shares of Sun Common Stock in connection with 
the satisfaction by the Company of its obligations under any employee benefit 
plans or the satisfaction by the Company of its obligations pursuant to any 
contract or security requiring the Company to purchase shares of Sun Common 
Stock, (B) as a result of a reclassification of the Company's capital stock 
or the exchange or conversion of one class or series of the Company's capital 
stock for another class or series of the Company's capital stock or (C) the 
purchase of fractional interests in shares of the Company's capital stock 
pursuant to the conversion or exchange provisions of such capital stock or 
the security being converted or exchanged) or make any guarantee payments 
with respect to the foregoing, (ii) not make any payment of interest, 
principal or premium, if any, on or repay, repurchase or redeem any debt 
securities (including guarantees) issued by the Company that rank PARI PASSU 
with or junior to the Convertible Debentures (except by conversion into or 
exchange for shares of its capital stock) and (iii) not make any guarantee 
payments with respect to the foregoing (other than pursuant to the 
Guarantee).  Prior to the termination of any such Extension Period, the 
Company may further extend such Extension Period; PROVIDED, that such 
Extension Period, together with all such previous and further extensions 
thereof, may not exceed 20 consecutive quarters or extend beyond the maturity 
date of the Convertible Debentures.  Upon the termination of any Extension 
Period and the payment of all amounts then due, the Company may commence a 
new Extension Period, subject to the above requirements.  No interest during 
an Extension Period shall be due and payable.  Notwithstanding anything to 
the contrary, the Company shall not have the right at any time to defer any 
Additional Interest, including by extending the interest payment period.
          If the Property Trustee is the sole Holder of the Convertible 
Debentures at the time the Company selects an Extension Period, the Company 
shall give written notice to the Administrative Trustees, the Property 
Trustee and the Trustee of its selection of such Extension Period at least 
one Business Day prior to the earlier of (i) the date the distributions on 
the Convertible Preferred Securities are payable or (ii) if the Convertible 
Preferred Securities are listed on the New York Stock Exchange or other stock 
exchange or quotation system, the date the Trust is required to give notice 
to the New York Stock Exchange or other applicable self-regulatory 
organization or to holders of the Convertible Preferred Securities of the 
record date or the date such distributions are payable, but in any event not 
less than 10 Business Days prior to such record date.
                                     -9-
          If the Property Trustee is not the sole holder of the Convertible 
Debentures at the time the Company selects an Extension Period, the Company 
shall give the Holders of the Convertible Debentures and the Trustee written 
notice of its selection of such Extension Period at least ten Business Days 
prior to the earlier of (i) the next succeeding Interest Payment Date or (ii) 
if the Convertible Preferred Securities are listed on the New York Stock 
Exchange or other stock exchange or quotation system, the date the Company is 
required to give notice to the New York Stock Exchange or other applicable 
self-regulatory organization or to holders of the Convertible Debentures on 
the record or payment date of such related interest payment, but in any event 
not less than two Business Days prior to such record date.
          The quarter in which any notice is given pursuant to paragraphs 
second and third of this Section 2 shall be counted as one of the 20 quarters 
permitted in the maximum Extension Period permitted under paragraph one of 
this Section 2.
          (3)  PAYING AGENT AND SECURITY REGISTRAR.  The Trustee will act as 
Paying Agent, Security Registrar and Conversion Agent.  The Company may 
change any Paying Agent, Security Registrar, co-registrar or Conversion Agent 
without prior notice.  The Company or any of its Affiliates may act in any 
such capacity.
          (4)  REDEMPTION.  The Company shall have the right to redeem the 
Convertible Debentures, in whole or in part, at any time or from time to time 
after  May 3, 2001 upon not less than 30 nor more than 60 days' notice, at 
the optional redemption prices (expressed as a percentage of the principal 
amount of Convertible Debentures to be redeemed) shown below, plus any 
accrued and unpaid interest (including Additional Payments, if any) to the 
Redemption Date, if redeemed during the 12-month period beginning May 3,:

     Year                                        Amount   
     ----                                     -------------

     2005 and thereafter  . . . . . . . .         100.000%
          If the Company has deferred interest payments, all unpaid interest 
must be paid in cash prior to redemption.  Any redemption pursuant to this 
Section 1101 shall be made pursuant to the provisions of Sections 1103 
through 1108 hereof.
                                     -10-
          The Convertible Debentures are subject to redemption in whole (but 
not in part), at any time within 90 days, if a Tax Event (as defined in the 
Declaration) shall occur and be continuing, at a redemption price equal to 
100% of the principal amount thereof plus accrued but unpaid interest 
(including Additional Payments, if any) to the Redemption Date.  On and after 
the Redemption Date, interest ceases to accrue on the Convertible Debentures 
or portions of them called for 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 Convertible Debentures to be redeemed, at 
such Holder's address appearing in the Security Register.  The Convertible 
Debentures in denominations larger than $25 may be redeemed in part but only 
in integral multiples of $25.  In the event of a redemption of less than all 
of the Convertible Debentures, the Convertible Debentures will be chosen for 
redemption by the Trustee in accordance with the Indenture.
          If this Convertible Debenture is redeemed subsequent to a Regular 
Record Date with respect to any Interest Payment Date specified above and on 
or prior to such Interest Payment Date, then any accrued interest will be 
paid to the person in whose name this Convertible Debenture is registered at 
the close of business on such record date.
          (5)  SINKING FUND.  The Convertible Debentures are not entitled to 
the benefit of any sinking fund.
          (6)  SUBORDINATION.  The payment of the principal of, premium, if 
any, and interest (including Additional Payments, if any) on all Convertible 
Debentures is subordinated and junior in right of payment to the prior 
payment in full of all existing and future Senior Indebtedness, whether 
outstanding at the date of this Indenture or thereafter incurred.  Each 
holder, by accepting a Convertible Debenture, agrees to such subordination 
and authorizes and directs the Trustee on its behalf to take such action as 
may be necessary or appropriate to effectuate the subordination so provided 
and appoints the Trustee as its attorney-in-fact for such purpose.

principal, premium, if any, and interest in respect of (A) indebtedness of 
such obligor for money borrowed and (B) indebtedness evidenced by securities, 
debentures, bonds or other similar instruments issued by such obligor,

lease obligations of such obligor, (iii) all obligations of such obligor 
issued or assumed as the deferred purchase price of property, all conditional 
sale obligations of such obligor and all obligations of such obligor under

through (v) above of other Persons secured by any lien on any property or 
asset of such obligor (whether or not such obligation is assumed by such

subordinated to or PARI PASSU with the Convertible Debentures and (2) any 
indebtedness between or among such obligor or its affiliates, including all 
other debt securities and guarantees in respect of those debt securities

vehicle of the Company (a "Financing Entity") in connection with the issuance 
by such Financing Entity of Convertible Preferred Securities or other 
securities which rank PARI PASSU with, or junior to, the Convertible 
Preferred Securities, unless otherwise provided in the terms of such debt 
securities.  Such Senior Indebtedness shall continue to be Senior 
Indebtedness and entitled to the benefits of the subordination provisions 
irrespective of any amendment, modification or waiver of any term of such 
Senior Indebtedness, except as otherwise provided in the exception clauses 
above.
          (7)  CONVERSION.  The Holder of any Convertible Debenture has the 
right, exercisable at any time on or before 5:00 p.m. (New York City time) on 
the Business Day immediately preceding the date of repayment of such 
Convertible Debentures, whether at maturity or upon redemption (either at the 
option of the Company or pursuant to a Tax Event), 
                                       -12-
to convert the principal amount thereof (or any portion thereof that is an 
integral multiple of $25) into fully paid and nonassessable shares of Sun 
Common Stock of the Company at an initial conversion rate of 1.2419 shares of 
Sun Common Stock for each $25 in aggregate principal amount of Convertible 
Debentures (equal to a conversion price of $20.13  per share of Sun Common 
Stock), subject to adjustment under certain circumstances as set forth in 
Section 1303 and 1304. The number of shares issuable upon conversion of a 
Convertible Debenture is determined by dividing the principal amount of the 
Convertible Debenture converted by the conversion price in effect on the 
Conversion Date.  No fractional shares will be issued upon conversion but a 
cash adjustment will be made for any fractional interest.  The outstanding 
principal amount of any Convertible Debenture shall be reduced by the portion 
of the principal amount thereof converted into shares of Sun Common Stock.
          To convert a Convertible Debenture, a Holder must (i) complete and 
sign a conversion notice substantially in the form attached hereto, 
(ii) surrender the Convertible Debenture to a Conversion Agent, (iii) furnish 
appropriate endorsements or transfer documents if required by the Security 
Registrar or Conversion Agent and (iv) pay any transfer or similar tax, if 
required.  If a Notice of Conversion is delivered on or after the Regular 
Record Date and prior to the subsequent Interest Payment Date, the Holder 
will be entitled to receive the interest payable on the subsequent Interest 
Payment Date on the portion of Convertible Debentures to be converted 
notwithstanding the conversion thereof prior to such Interest Payment Date.  
Except as otherwise provided in the immediately preceding sentence, in the 
case of any Convertible Debenture which is converted, interest whose Stated 
Maturity is after the date of conversion of such Convertible Debenture shall 
not be payable, and the Company shall not make nor be required to make any 
other payment, adjustment or allowance with respect to accrued but unpaid 
interest (including Additional Payments, if any) on the Convertible 
Debentures being converted, which shall be deemed to be paid in full.  If any 
Convertible Debenture called for redemption is converted, any money deposited 
with the Trustee or with any Paying Agent or so segregated and held in trust 
for the redemption of such Convertible Debenture shall (subject to any right 
of the Holder of such Convertible Debenture or any Predecessor Security to 
receive interest as provided in the last paragraph of Section 307 and this 
paragraph) be paid to the Company upon Company Request or, if then held by 
the Company, shall be discharged from such trust.
          (8)  REGISTRATION RIGHTS.  The holders of the Convertible Preferred 
Securities, the Convertible Debentures issuable in respect of the Convertible 
Preferred Securities, the shares of Sun Common Stock issuable upon conversion 
of the Convertible Preferred Securities and the Convertible Debentures, and 
the Guarantee (collectively, the "REGISTRABLE SECURITIES") are entitled to 
the benefits of a Registration Rights Agreement, dated as of May 4, 1998, 
between the Company and the Initial Purchasers (the "REGISTRATION RIGHTS 
AGREEMENT"). 
                                       -13-
Pursuant to the Registration Rights Agreement, the Company has agreed for the 
benefit of the holders of Registrable Securities that (i) it will, at its 
cost, use its reasonable best efforts within 90 days after the date of 
original issuance of the Registrable Securities, to file a shelf registration 
statement (the "SHELF REGISTRATION STATEMENT") with the Commission with 
respect to the resales of the Registrable Securities, (ii) it will use its 
reasonable best efforts to cause such Shelf Registration Statement to be 
declared effective by the Commission within 150 days after the date of 
issuance of the Registrable Securities and (iii) it will use its reasonable 
best efforts to maintain such Shelf Registration Statement continuously 
effective under the Securities Act until two years after the date of original 
issuance of the Convertible Preferred Securities (or such earlier date as the 
holders of Registrable Securities are able to sell all Registrable Securities 
immediately without restriction, whether pursuant to Rule 144(k) under the 
Securities Act or any successor rule thereto or otherwise) (the 
"EFFECTIVENESS PERIOD") or such holders have sold all such Registrable 
Securities pursuant to an effective Registration Statement.  The Trust and 
the Company will be permitted to suspend the use of the prospectus (which is 
a part of the Shelf Registration Statement) in connection with sales of 
Registrable Securities by holders during certain periods of time under 
certain circumstances relating to pending corporate developments relating to 
the Company and public filings with the Commission and similar events.
          If (i) on or prior to 90 days following the date of original issuance
          of the Registrable Securities, a Shelf Registration Statement has not
          been filed with the Commission or (ii) on or prior to the 150th day
          following the original issuance of the Registrable Securities, such
          Shelf Registration Statement has not been declared effective (each
          such event a "REGISTRATION DEFAULT"), additional interest ("LIQUIDATED
          DAMAGES") will accrue on the Convertible Debentures and, accordingly,
          additional distributions will accrue on the Convertible Preferred
          Securities, from and including the day following such Registration
          Default until such time as such Shelf Registration Statement is filed
          or such Shelf Registration Statement is declared effective, as the
          case may be.  Liquidated Damages will be paid quarterly in arrears
          (subject to the Company's ability to defer payment of Liquidated
          Damages during any Extension Period), with the first quarterly payment
          due on the first Interest Payment Date following the date on which
          such Liquidated Damages begin to accrue, and will accrue at a rate per
          annum equal to an additional 0.25% of the principal amount or
          liquidation amount, as applicable, to and including the 90th day
          following such Registration Default and 0.50% thereof from and after
          the 91st day following such Registration Default.  The curing of any
          Registration Default will reset the rate at which Liquidated Damages
          begin to accrue for any subsequent new Registration Default to a rate
          per annum equal to an additional one-quarter of one percent (0.25%) of
          the 
                                       -14-
          principal amount or liquidation amount, as applicable, to and
          including the 90th day following such Registration Default and
          one-half of one percent (0.50%) thereof from and after the 91st day
          following such new Registration Default.  The Guarantor shall have the
          right to suspend the Shelf Registration Statement under certain
          circumstances for up to 90 consecutive days. In the event that during
          the Effectiveness Period the Shelf Registration Statement ceases to be
          effective for more than 90 consecutive days or any 120 days, whether
          or not consecutive, during any 12-month period then the interest rate
          borne by the Debentures and the distribution rate borne by the
          Convertible Preferred Securities will each increase by an additional
          0.25% per annum from such 91st or 121st day, as applicable, of the
          applicable 12-month period such Shelf Registration Statement ceases to
          be effective until the earlier of such time as (i) the Shelf
          Registration Statement again becomes effective or (ii) the
          Effectiveness Period expires.
          The summary of certain provisions of the Registration Rights 
Agreement in this Section 8 is subject to, and is qualified in its entirety, 
by reference to the Registration Rights Agreement.
          (9)  REGISTRATION, TRANSFER, EXCHANGE AND DENOMINATIONS.  As 
provided in the Indenture and subject to certain limitations therein set 
forth, the transfer of this Convertible Debenture is registrable in the 
Security Register, upon surrender of this Convertible Debenture for 
registration of transfer at the office or agency of the Company in New York, 
New York, duly endorsed by, or accompanied by a written instrument of 
transfer in form satisfactory to the Company and the Security Registrar duly 
executed by, the Holder hereof or his attorney duly authorized in writing, 
and thereupon one or more new Convertible Debentures, of authorized 
denominations and for the same aggregate principal amount, will be issued to 
the designated transferee or transferees.
          The Convertible Debentures are issuable only in registered form 
without coupons in denominations of $25 and integral multiples thereof.  No 
service charge shall be made for any such registration of transfer or 
exchange, but the Company may require payment of a sum sufficient to cover 
any tax or other governmental charge payable in connection therewith.  Prior 
to due presentment of this Convertible Debenture for registration of 
transfer, the Company, the Trustee and any Agent of the Company or the 
Trustee may treat the Person in whose name this Convertible Debenture is 
registered as the owner hereof for all purposes, whether or not this 
Convertible Debenture be overdue, and neither the Company, the Trustee nor 
any such Agent shall be affected by notice to the contrary.  In the event of 
redemption or conversion of this Convertible Debenture in part only, a new 
Convertible Debenture or Convertible Debentures 
                                       -15-
for the unredeemed or unconverted portion hereof will be issued in the name 
of the Holder hereof upon the cancellation hereof.
          (10) PERSONS DEEMED OWNERS.  Except as provided in the Indenture, 
the registered Holder of a Convertible Debenture may be treated as its owner 
for all purposes.
          (11) UNCLAIMED MONEY.  If money for the payment of principal or 
interest remains unclaimed for two years, the Trustee and the Paying Agent 
shall pay the money back to the Company at its written request.  After that, 
Holders of Convertible Debentures entitled to the money must look to the 
Company for payment unless an abandoned property law designates another 
Person and all liability of the Trustee and such Paying Agent with respect to 
such money shall cease.
          (12) DEFAULTS AND REMEDIES.  The Convertible Debentures shall have 
the Events of Default as set forth in Section 501 of the Indenture.  Subject 
to certain limitations in the Indenture, if an Event of Default occurs and is 
continuing, the Trustee by notice to the Company or the Holders of at least 
25% in aggregate principal amount of the then outstanding Convertible 
Debentures by notice to the Company and the Trustee may declare all the 
Convertible Debentures to be due and payable immediately.
          The Holders of a majority in principal amount of the Convertible 
Debentures then outstanding by written notice to the Trustee may rescind an 
acceleration and its consequences if the rescission would not conflict with 
any judgment or decree and if all existing Events of Default have been cured 
or waived except nonpayment of principal or interest that has become due 
solely because of the acceleration.  Holders may not enforce the Indenture or 
the Convertible Debentures except as provided in the Indenture.  Subject to 
certain limitations, Holders of a majority in principal amount of the then 
outstanding Convertible Debentures issued under the Indenture may direct the 
Trustee in its exercise of any trust or power.  The Convertible Debentures 
are unsecured general obligations of the Company.  The Company must furnish 
annually compliance certificates to the Trustee.  The above description of 
Events of Default and remedies is qualified by reference to, and subject in 
its entirety by, the more complete description thereof contained in the 
Indenture.
          (13) AMENDMENTS, SUPPLEMENTS AND WAIVERS.  The Indenture permits, 
with certain exceptions as therein provided, the amendment thereof and the 
modification of the rights and obligations of the Company and the rights of 
the Holders of the Convertible Debentures under the Indenture at any time by 
the Company and the Trustee with the consent of the Holders of a majority in 
aggregate principal amount of the Convertible Debentures at the time 
Outstanding.  The Indenture also contains provisions permitting the Holders of
                                       -16-
specified percentages in aggregate principal amount of the Convertible 
Debentures at the time Outstanding, on behalf of the Holders of all the 
Convertible Debentures, to waive compliance by the Company with certain 
provisions of the Indenture and certain past defaults under the Indenture and 
their consequences.  Any such consent or waiver by the Holder of this 
Convertible Debenture shall be conclusive and binding upon such Holder and 
upon all future Holders of this Convertible Debenture and of any Convertible 
Debenture issued upon the registration of transfer hereof or in exchange 
herefor or in lieu hereof, whether or not notation of such consent or waiver 
is made upon this Convertible Debenture.
          (14) TRUSTEE DEALINGS WITH THE COMPANY.  The Trustee, in its 
individual or any other capacity may become the owner or pledgee of the 
Convertible Debentures and may otherwise deal with the Company or an 
Affiliate with the same rights it would have, as if it were not Trustee, 
subject to certain limitations provided for in the Indenture and in the TIA.  
Any Agent may do the same with like rights.
          (15) NO RECOURSE AGAINST OTHERS.  A director, officer, employee or 
stockholder, as such, of the Company shall not have any liability for any 
obligations of the Company under the Convertible Debentures or the Indenture 
or for any claim based on, in respect of or by reason of such obligations or 
their creation.  Each Holder of the Convertible Debentures by accepting a 
Convertible Debenture waives and releases all such liability.  The waiver and 
release are part of the consideration for the issue of the Convertible 
Debentures.
          (16) GOVERNING LAW.  THE INTERNAL LAWS OF THE STATE OF NEW YORK 
SHALL GOVERN THE INDENTURE AND THE CONVERTIBLE DEBENTURES WITHOUT REGARD TO 
CONFLICT OF LAW PROVISIONS THEREOF.
          (17) AUTHENTICATION.  The Convertible Debentures shall not be valid 
until authenticated by the manual signature of an authorized officer of the 
Trustee or an authenticating Agent.
                                       -17-
