The Company may from time to time offer Notes for sale otherwise than through the Agent; provided, however, that so long as this Agreement shall be in effect the Company shall not solicit offers to purchase Notes through any other agent without amending this Agreement to appoint such agent as an additional Agent hereunder on the same terms and conditions as provided herein for the Agent and without giving Agent prior notice of such appointment. The consent of the then-current Agents shall not be necessary for such purpose.

On the basis of the representations and warranties contained herein, but subject to the terms and conditions herein set forth, the Agent agrees, as an agent of the Company, to use its reasonable efforts to solicit offers to purchase the Notes upon the terms and conditions set forth in the Prospectus. Except as otherwise provided herein, so long as this Agreement shall remain in effect, the Company shall not, without the consent of the Agent, solicit or accept offers to purchase Notes otherwise than through the Agent provided, however, the Company expressly reserves the right to sell Notes directly to investors, in which case no commission will be payable with respect to any such 9 9 sale. The Agent may also purchase Notes from the Company as principal for purposes of resale, as more fully described in paragraph (e) of this Section. (b) Suspension of Solicitation. The Company reserves the right, in its sole discretion, to suspend solicitation of offers to purchase the Notes commencing at any time for any period of time or indefinitely.

The Agent shall communicate to the Company, orally or in writing, each reasonable offer to purchase Notes received by it as Agent. The Company shall have the sole right to accept offers to purchase the Notes and may reject any such offer in whole or in part. The Agent shall have the right, in its discretion reasonably exercised without advising the Company, to reject any offer to purchase the Notes received by it, in whole or in part, and any such rejection shall not be deemed a breach of its agreement contained herein. No Note which the Company has agreed to sell pursuant to this Agreement shall be deemed to have been purchased and paid for, or sold by the Company, until such Note shall have been delivered to the purchaser thereof against payment by such purchaser. (e) Purchases as Principal. Each sale of Notes to the Agent as principal, for resale to one or more investors or to another broker-dealer (acting as principal for purposes of resale), shall be made in accordance with the terms of this Agreement and a Purchase Agreement whether oral (and confirmed in writing by such Agent to the Company, which may be by facsimile transmission) or in writing, which will provide for the sale of such Notes to, and the purchase thereof by, the Agent. A Purchase Agreement may also specify certain provisions relating to the reoffering of such Notes by the Agent. The commitment of the Agent to purchase Notes from the Company as principal shall be deemed to have been made on the basis of the representations and warranties of the Company herein contained and shall be subject to the terms and conditions herein set forth. Each Purchase Agreement shall contain, to the extent applicable, those terms specified in Exhibit A hereto, including the time and date (each such time and date being referred to herein as a "Time of Delivery") and place of delivery of and payment for such Notes and such other information (as applicable) as is set forth in Exhibit C hereto. The Company agrees that if the Agent purchases Notes as principal for resale such Agent shall receive such compensation, in the form of a discount or otherwise, as shall be indicated in 10 10 the applicable Purchase Agreement or, if no compensation is indicated therein, a commission in accordance with Schedule A hereto.

The Agent may sell Notes to any dealer at a discount and, unless otherwise specified in the applicable Pricing Supplement, such discount allowed to any dealer will not be in excess of 66 2/3% of the discount to be received by such Agent from the Company. Such Purchase Agreement shall also specify any requirements for delivery of opinions of counsel, accountant's letters and officers' certificates pursuant to Section 5 hereof.

Administrative procedures respecting the sale of Notes (the "Procedures") are set forth in Exhibit B hereto and may be amended in writing from time to time by the Agent and the Company. The Agent and the Company agree to perform the respective duties and obligations specifically provided to be performed by each of them herein and in the Procedures. The Procedures shall apply to all transactions contemplated hereunder including sales of Notes to the Agent as principal pursuant to a Purchase Agreement, unless otherwise set forth in such Purchase Agreement.

based upon the Secretary's Certificate attached thereto as Exhibit A and certificates of good standing or qualification received from the respective state governmental agencies, each of Sun, the Company and the Principal Subsidiary is duly qualified to do business and in good standing as a foreign corporation, limited partnership or limited liability company, as the case may be, in all jurisdictions in which its respective ownership of properties or the conduct of its respective businesses requires such qualification (except where the failure to so qualify would not have a material adverse effect on the Company and the Subsidiaries taken as a whole), and has all power and authority necessary to own its respective properties and conduct the businesses in which it is engaged, as described in the Prospectus; provided, however, that this opinion shall not apply with respect to any states in which Sun, the Company or any of their subsidiaries are required to be qualified to do business solely as a result of the sale of the securities of the Company, Sun or their subsidiaries; all of the issued and outstanding capital stock of each corporate Principal Subsidiary has been duly authorized and validly issued and is fully paid and nonassessable, and, except as set forth in the Prospectus, all of such capital stock is owned by the Company, directly or through Subsidiaries, free and clear of any mortgage, pledge, lien, claim or encumbrance;

(v) Such counsel does not know of any contracts or other documents which are required to be filed as exhibits to the Registration Statement by the Act or by the Rules and Regulations, or which are required to be filed by the Exchange Act or the rules and regulations of the Commission thereunder as exhibits to any document incorporated by reference in the Prospectus, which have not been filed as exhibits to the Registration Statement or to such document or incorporated therein by reference as permitted by the Rules and Regulations or the rules and regulations of the Commission under the Exchange Act; (vi) To the best of such counsel's knowledge, neither the Company nor any of the Subsidiaries is in violation of its certificate of limited partnership, partnership agreement, corporate charter or by-laws, or in default (except where such default would not have a material adverse effect upon the Company and the Subsidiaries taken as a whole) under any agreement, indenture or instrument; (vii) The Indenture has been duly authorized by Sun and the Company, duly executed and delivered by Sun and the Company and duly qualified under the Trust Indenture Act and is a valid and legally binding obligation of Sun and the Company enforceable in accordance with its terms;

(ix) The execution, delivery and performance of this Agreement and the Purchase Agreement, if any, and compliance by Sun and the Company with the provisions of the Notes and the Indenture will not conflict with, or result in the creation or imposition of any lien, charge or encumbrance upon any of the assets of Sun, the Company or any of the Subsidiaries pursuant to the terms of, or constitute a default under, any agreement, indenture or instrument known to such counsel, or result in a violation of the certificate of limited partnership, partnership agreement, corporate charter or by-laws of Sun, the Company or any of the Subsidiaries (as in effect on the date of such opinion) or any order, rule or regulation (also as 16 16 in effect on the date of such opinion) of any court or governmental agency having jurisdiction over Sun, the Company, any of the Subsidiaries or their respective properties; and no consent, authorization or order of, or filing or registration with, any court or governmental agency is required for the execution, delivery and performance by Sun and the Company of this Agreement and the Purchase Agreement, if any, except such as may be required by the Act, the Trust Indenture Act, the Exchange Act or state securities laws;

(xii) To the knowledge of such counsel, no order directed to any document incorporated by reference in the Prospectus has been issued and no challenge has been made to the accuracy or adequacy of any such document;

it being understood that such counsel need express no opinion as to the financial statements or other financial or statistical information contained or incorporated therein or omitted therefrom; (xiii) The Registration Statement and the Prospectus (except that no opinion need be expressed as to the financial statements and other financial data contained therein or the Form T-1 that is an exhibit thereto) comply as to form in all material respects with the requirements of the Act and the Trust Indenture Act and the rules and regulations of the Commission under said Acts;

(xiv) The statements made in the Prospectus under the captions "Description of Debt Securities," "Description of the Notes" and "Special Provisions Relating to Multi-Currency Notes," insofar as they purport to summarize the provisions of documents or agreements specifically referred to therein, fairly present the information called for with respect thereto by Form S-3; (xv) Sun and the Company each has the corporate or partnership power and authority necessary to execute and deliver this Agreement and the Purchase Agreement, if any, and to perform its respective obligations (including the sale and delivery by the Company of the Notes under this Agreement);

and (xvii) The descriptions contained in the Prospectus under the heading "Federal Income Tax Considerations" and "Certain United States Federal Income Tax Considerations," while not purporting to discuss all possible income tax ramifications of the proposed issuance, is correct in all material respects; and the most recently filed opinion of such counsel filed as Exhibit 8.1 to the Registration Statement is confirmed and the Agent may rely on such opinion as though addressed to it; (xviii) Each partnership agreement to which the Company or any of the Subsidiaries is a party, and which relates to real property described in the Prospectus, has been duly authorized, executed and delivered by such applicable party and constitutes the valid agreement thereof, enforceable in accordance with its terms. The execution, delivery and performance of any of such agreements did not, at the time of execution and delivery, and does not constitute a breach of, or a default under, the charter, partnership agreement or by-laws of the Company or the Subsidiaries or, except where such breach or default would not have a material adverse effect on the Company, any material contract, lease or other instrument to which the Company or any of the Subsidiaries is a party or to which any of their properties may be bound or any law, administrative regulation or administrative or court decree. The opinions set forth in paragraphs (vii), (viii), (ix) and (xviii) above are subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors' rights generally, general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law), and except as enforceability thereof may be limited by (A) requirements that a claim with respect to any Notes payable other than in U.S. dollars (or a foreign currency or composite currency judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable law or (B) governmental authority to limit, delay or prohibit the making of payments outside the United States. In rendering such opinion, such counsel may rely as to matters of Maryland law on the opinion of Ober, Kaler Grimes & Shriver, or other Maryland counsel approved by the Agent, such approval not to be unreasonably withheld, delayed, or conditioned, which opinion shall be in form and substance satisfactory to counsel for the Agent, provided that such counsel shall state that it believes that both the Agent and it are justified in relying upon such opinion.

(or other independent accounts of the Company acceptable to the Agent) to furnish the Agent, (i) concurrently with such amendment, supplement, Time of Delivery relating to such sale or filing or (ii) if such amendment, supplement, or filing was not filed during a Marketing Period, on the first day of the next succeeding Marketing Period, a letter, addressed jointly to the Company and the Agent and dated the date of delivery of such letter, in form and substance reasonably satisfactory to the Agent, to the same effect as the letter referred to in Section 5(g) hereof but modified to relate to the Registration Statement and each Prospectus, as amended and supplemented to the date of such letter, with such changes as may be necessary to reflect changes in the financial statements and other information derived from the accounting records of the Company; provided, however, that if the Registration Statement or any Prospectus is amended or supplemented solely to include financial information as of and for a fiscal quarter, such accountants may limit the scope of such letter to the unaudited financial statements included in such amendment or supplement unless there is contained therein any other accounting, financial or statistical information that, in the reasonable judgment of the Agent, should be covered by such letter, in which event such letter shall also cover such other information. (e) Opinion on Settlement Date. On any settlement date for the sale of Notes, Sun and the Company shall, if requested by the Agent, furnish the Agent with a written opinion of outside counsel to Sun and the Company, dated such settlement date, in form satisfactory to the Agent, to the effect set forth in Section 5(e) hereof, but modified, as necessary, to relate to the Prospectus relating to the Notes to be delivered on such settlement date; provided, however, that in lieu of such opinion, such counsel may furnish the Agent with a letter to the effect that the Agent may rely on such prior opinion to the same extent as though it was dated such settlement date (except that statements in such prior opinion shall be deemed to relate to the Registration Statement and such Prospectus as amended or supplemented to the time of delivery of such letter authorizing reliance). Section 7. INDEMNIFICATION AND CONTRIBUTION (a) Indemnification of Agent. The Company shall indemnify and hold harmless the Agent and each person, if any, who controls the Agent within the meaning of the Act from and against any loss, claim, damage or liability, joint or several, and any action in respect thereof, to which the Agent 22 22 or controlling person may become subject, under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus, or arises out of, or is based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse the Agent and controlling person for any legal and other expenses reasonably incurred by the Agent or controlling person in investigating or defending or preparing to defend against any such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Form T-1 or made in the Registration Statement or the Prospectus in reliance upon and in conformity with written information furnished to the Company by the Agent specifically for inclusion therein; provided further, that as to any prospectus included in the Registration Statement before it became effective under the Act (a "Preliminary Prospectus") this indemnity agreement shall not inure to the benefit of the Agent on account of any loss, claim, damage, liability or action arising from the sale of Notes to any person by the Agent if the Agent failed to send or give a copy of the Prospectus, as the same may be amended or supplemented, to that person within the time required by the Act, and the untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact in such Preliminary Prospectus was corrected in the Prospectus, unless such failure resulted from noncompliance by the Company with Section 3(b). The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to the Agent or controlling person. (b) Indemnification of the Company. The Agent shall indemnify and hold harmless the Company, each of Sun's directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of Sun), each of its officers who signed the Registration Statement and any person who controls the Company within the meaning of the Act from and against any loss, claim, damage or liability, joint or several, and any action in respect thereof, to which the Company or any such director, officer or controlling person may become subject, under the Act, the Exchange Act or federal or state statutory law or regulation, at common law or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus, or arises out of, or is based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Agent specifically for inclusion therein, and shall reimburse the Company or any such director, officer or controlling person for any legal and other expenses reasonably incurred by such indemnified party in investigating or defending or preparing to defend against any such loss, claim, damage, liability or action. The foregoing indemnity agreement is in addition to any liability which the Agent may otherwise have to the Company or any such director, officer or controlling person. (c) Notice. Promptly after receipt by an indemnified party under this Section of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section except to the extent it has been materially prejudiced by such failure. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein, 23 23 and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Agent shall have the right to employ counsel to represent the Agent if, in the reasonable judgment of the Agent, it is advisable for the Agent to be represented by separate counsel, and in that event the fees and expenses of such counsel shall be paid by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. (d) Contribution. If the indemnification provided for in this Section 7 shall for any reason be unavailable to an indemnified party under Section 7(a) or 7(b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Agent on the other from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Agent on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Agent on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes (before deducting expenses) received by the Company bears to the total commissions received by the Agent with respect to such offering. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Agent, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Agent agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), the Agent shall not be required to contribute any amount in excess of the amount by which the total price at which the Notes sold through the Agent and distributed to the public were offered to the public exceeds the amount of any damages which the Agent has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 24 24 Section 8. STATUS OF THE AGENT In soliciting offers to purchase the Notes from the Company pursuant to this Agreement (other than in respect of any Purchase Agreement), the Agent is acting solely as agent for the Company and not as principal. The Agent will make reasonable efforts to assist the Company in obtaining performance by each purchaser whose offer to purchase Notes from the Company has been solicited by the Agent and accepted by the Company but the Agent shall have no liability to the Company in the event any such purchase is not consummated for any reason. If the Company shall default in its obligations to deliver Notes to a purchaser whose offer it has accepted, the Company shall (i) hold the Agent harmless against any loss, claim or damage arising from or as a result of such default by the Company and (ii), in particular, pay to the Agent any commission to which it would be entitled in connection with such sale. Section 9. REPRESENTATIONS, WARRANTIES AND OBLIGATIONS TO SURVIVE DELIVERY The respective indemnities, agreements, representations, warranties and other statements of the Company and the Agent contained in this Agreement, or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Agent or any person controlling the Agent or by or on behalf of the Company, and shall survive each delivery of and payment for any of the Notes. Section 10. TERMINATION This Agreement may be terminated for any reason with respect to any party hereto, at any time, by any party hereto upon the giving of one day's written notice of such termination to the other parties hereto. If, at the time of a termination, an offer to purchase any of the Notes has been accepted by the Company but the time of delivery to the purchaser has not occurred, the provisions of this Agreement shall remain in effect until such Notes are delivered. The provisions of Sections 2(c), 3(d), 3(h), 3(i), 4, 7, 8 and 9 hereof shall survive any termination of this Agreement. Section 11. SALES OF NOTES DENOMINATED IN A FOREIGN CURRENCY AND INDEXED NOTES If at any time the Company and the Agent shall determine to issue and sell Notes denominated in a currency or currency unit other than U.S. Dollars, which other currency may include a composite currency, or with respect to which an index is used to determine the amounts of payments of principal and any premium or interest, the Company and the Agent shall execute and deliver an Amendment (a "Foreign Currency Amendment" or "Indexed Note Amendment," as the case may be) in the form attached hereto as Exhibit D. Such amendment shall establish, as appropriate additions and modifications that shall apply to the sales, whether offered on an agency or principal basis, of the Notes covered thereby. Section 12. NOTICES Except as otherwise provided herein, all notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

Section 13. BINDING EFFECT; BENEFITS This Agreement shall be binding upon the Agent, Sun, the Company, and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (a) the representations, warranties, indemnities and agreements of Sun and the Company contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control the Agent within the meaning of Section 15 of the Act, and (b) the indemnity agreement of the Agent contained in Section 7 hereof shall be deemed to be for the benefit of directors of Sun (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of Sun), officers of Sun who have signed the Registration Statement and any person controlling the Company. Nothing in this Agreement is intended or shall be construed to give any person, other than the person referred to in this Section, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. Section 14. GOVERNING LAW; COUNTERPARTS This Agreement shall be governed by and construed in accordance with the laws of the State of New York. This Agreement may be executed in counterparts and the executed counterparts shall together constitute a single instrument. Section 15.

Lehman Brothers Inc., as agent (the "Agent"), has agreed to use its reasonable best efforts to solicit offers to purchase the Notes. The Notes are being sold pursuant to a Distribution Agreement between the Company and the Agent dated _______________ ___, 1997 (as it may be supplemented or amended from time to time, the "Distribution Agreement") to which these administrative procedures are attached as an exhibit. The Notes will be issued under an indenture, dated as of April 24, 1996, between the Company, Sun Communities, Inc. ("Sun"), the general partner of the Company, and Bankers Trust Company, as trustee (the "Trustee"), as heretofore supplemented. The Notes will rank equally with all other unsecured and unsubordinated indebtedness of the Company and will have been registered with the Securities and Exchange Commission (the "Commission"). Terms defined in the Prospectus relating to the Notes (the "Prospectus") and in the Distribution Agreement shall have the same meaning when used in this exhibit. Special administrative procedures for Multi-Currency Notes and for Global Securities relating to Book-Entry Notes follow these administrative procedures. Administrative responsibilities, document control and record-keeping functions to be performed on behalf of the Company will be performed by Sun's Chief Financial Officer. Administrative procedures for the offering are explained below. PRICE TO PUBLIC Each Note will be issued at 100% of principal amount, unless otherwise determined by the Company. DATE OF ISSUANCE Each Note will be dated and issued as of the date of its authentication by the Trustee. MATURITIES Each Note will mature on a Business Day (as defined below) selected by the purchaser and agreed upon by the Company, such date being at least nine months from the date of issuance. Each Floating Rate Note will mature on an Interest Payment Date (as defined below). "Business Day" shall mean any day which is not a Saturday or Sunday and which is not a day on which banking institutions are generally authorized or obligated by law to close in The City of New York. REGISTRATION Notes will be issued only in fully registered form as either a Book-Entry Note or a Certificated Note. Certificated Notes may be presented for registration of transfer or exchange at the Trustee's New York office. 30 B-2 DENOMINATIONS The Notes (other than Notes represented by Global Securities) will be issued and payable in U.S. dollars in the denomination of $1,000 and any larger denomination which is an integral multiple of $1,000. INTEREST PAYMENTS Each Note bearing interest at a fixed rate (a "Fixed Rate Note") will bear interest from its issue date at the annual rate stated on the face thereof, payable on May 1 and November 1 of each year (each an "Interest Payment Date" with respect to such Fixed Rate Note) and at Stated Maturity or upon redemption, if applicable. Special provisions are set forth in the Prospectus relating to Notes bearing interest at a rate or rates determined by reference to an interest rate formula ("Floating Rate Notes") at a rate determined pursuant to the formula stated on the face thereof, payable in arrears on such dates as are specified therein (each an "Interest Payment Date" with respect to such Floating Rate Note). Interest on Fixed Rate Notes will be calculated and paid on the basis of a 360-day year of twelve 30-day months. Interest will be payable to the person in whose name such Note is registered at the close of business on the fifteenth day (whether or not a Business Day) next preceding an Interest Payment Date with respect to Fixed Rate Notes or Floating Rate Notes (the "Record Dates") next preceding the respective Interest Payment Date; provided, however, that interest payable at Stated Maturity will be payable to the person to whom principal shall be payable. Any payment of principal and interest on such Note required to be paid on an Interest Payment Date or at Stated Maturity or upon redemption, if applicable, which is not a Business Day shall be postponed to the next day which is a Business Day. The first payment of interest on any Note originally issued between a Record Date and an Interest Payment Date will be made on the Interest Payment Date following the next succeeding Record Date. All interest payments, excluding interest payments made at Stated Maturity or upon redemption, if applicable, will be made by check mailed to the person entitled thereto as provided above, or, at the option of the Company, by wire transfer to an account maintained by such person with a bank located in the United States. Notwithstanding the foregoing, the holder of $10 million or more in aggregate principal amount of Notes with the same Interest Payment Date may request payment by wire transfers. On the fifth Business Day immediately preceding each Interest Payment Date, the Trustee will furnish the Company with the total amount of the interest payments to be made on such Interest Payment Date. The Trustee (or any duly selected paying agent) will provide monthly to the Company's Treasury Department a list of the principal and interest to be paid on Notes maturing in the next succeeding month. The Company will provide to the Trustee not later than the payment date sufficient moneys to pay in full all principal and interest payments due on such payment date. The Trustee will assume responsibility for withholding taxes on interest paid as required by law. ACCEPTANCE AND REJECTION OF OFFERS The Company shall have the sole right to accept offers to purchase Notes and may reject any such offer in whole or in part. The Agent shall promptly communicate to the Company, orally or in writing, each reasonable offer to purchase Notes from the Company received by it other than those rejected by the Agent. The Agent shall have the right, in its discretion reasonably exercised without advising the Company, to reject any offers in whole or in part. 31 B-3 SETTLEMENT The receipt of immediately available funds in U.S. Dollars by the Company in payment for a Note (less the applicable commission) and the authentication and issuance of such Note shall, with respect to such Note, constitute "Settlement." All offers accepted by the Company will be settled from one to five Business Days from the date of acceptance by the Company pursuant to the timetable for Settlement set forth below unless the Company and the purchaser agree to Settlement on a later date; provided, however, that the Company will so notify the Trustee of any such later date on or before the Business Day immediately prior to the Settlement date. SETTLEMENT PROCEDURES In the event of a purchase of Notes by the Agent, as principal, appropriate Settlement details will be set forth in the Purchase Agreement to be entered into between the Agent and the Company pursuant to the Distribution Agreement. In the event of the sale of a Multi- Currency Note or an Indexed Note, additional or different Settlement details may be set forth in the Amendment to be entered into between the Agent and the Company pursuant to the Distribution Agreement. Settlement procedures with regard to each Note sold through the Agent shall be as follows: A. The Agent will advise the Company by telephone, telex or facsimile, of the following Settlement information: 1. Exact name in which the Note is to be registered ("Registered Owner"). 2. Exact address of the Registered Owner and address for payment of principal and interest, if any. 3. Taxpayer identification number of the Registered Owner. 4. Principal amount of the Note (and, if multiple Notes are to be issued, denominations thereof). 5. Settlement date. 6. Stated Maturity. 7. Issue Price and any OID information. 8.

Agent's Commission (to be paid in the form of a discount from the proceeds remitted to the Company upon Settlement). B. The Company will confirm the above Settlement information to the Trustee by telephone, telex or facsimile, and the Trustee will assign a Note number to the transaction. If the Company rejects an offer, the Company will promptly notify the Agent and the Trustee by telephone. C. The Trustee will complete the first page of the preprinted 4-ply Note packet [Note: Such a packet need not be prepared if the Company is utilizing the book-entry system, see procedures below], the form of which was previously approved by the Company, the Agent and the Trustee. D. The Trustee will deliver the Note (with the attached white confirmation) and the yellow and blue stubs to the Agent. The Agent will acknowledge receipt of the Note by completing the yellow stub and returning it to the Trustee. E. The Agent will cause to be wire transferred to a bank account designated by the Company immediately available funds in U.S. dollars in the amount of the principal amount of the Note, less the applicable commission or discount, if any. F. The Agent will deliver the Note (with the attached white confirmation) to the purchaser against payment in immediately available funds in the amount of the principal amount of the Note. The Agent will deliver to the purchaser a copy of the most recent Prospectus applicable to the Note with or prior to any written offer of Notes, delivery of the Note and the confirmation and payment by the purchaser for the Note. G. The Agent will obtain the acknowledgement of receipt for the Note and Prospectus by the purchaser through the purchaser's completion of the blue stub. H. The Trustee will mail the pink stub to Sun's Chief Financial Officer. 33 B-5 SETTLEMENT PROCEDURES TIMETABLE For offers accepted by the Company, Settlement procedures "A" through "H" set forth above shall be completed on or before the respective times set forth below: SETTLEMENT PROCEDURE TIME (NEW YORK) =============================================================== A 5 PM on date of order B 3 PM on the Business Day prior to Settlement Date C-D 12 Noon on the Settlement Date E 2:15 PM on the Settlement date F-G 3 PM on the Settlement Date H 5 PM on Business Day after the Settlement Date FAILS In the event that a purchaser of a Note shall either fail to accept delivery of or make payment for such Note on the date fixed by the Company for Settlement, the Agent will immediately notify the Trustee and Sun's Chief Financial Officer by telephone, confirmed in writing, of such failure and return the Note to the Trustee. Upon the Trustee's receipt of the Note from the Agent, the Company will promptly return to the Agent an amount of immediately available funds in U.S. dollars equal to any amount previously transferred to the Company in respect of the Note pursuant to advances made by the Agent. Such returns will be made on the Settlement date, if possible, and in any event not later than 12 noon (New York City time) on the Business Day following the Settlement date. The Company will reimburse the Agent on an equitable basis for its loss of the use of the funds during the period when the funds were credited to the account of the Company. Upon receipt of the Note in respect of which the default occurred, the Trustee will mark the Note "cancelled," make appropriate entries in its records and deliver the Note to the Company with an appropriate debit advice. The Agent will not be entitled to any commission with respect to any Note which the purchaser does not accept or make payment for. PRICING REDEMPTION Except as otherwise specified in the applicable Pricing Supplement and on the Notes, the Notes will not be redeemable prior to their Stated Maturity. If so specified in a Pricing Supplement and on the Note, such Note will be subject to redemption by the Company, at any time on or after the date set forth on such supplement and the Note, in whole or from time to time in part, at the option of the Company, at the redemption price set forth therein, together with interest accrued thereon on the date of redemption. Notice of redemption shall be given by first-class mail postage prepaid, mailed not less than 30 days nor more than 60 days prior to the date of redemption, to each holder of Notes to be redeemed, in the manner and in accordance with the Indenture. In the event of redemption in part of any Note, a new Note for the amount of the unredeemed portion shall be issued in the name of the Holder upon cancellation of the redeemed Note. 34 B-6 MATURITY Upon presentation of each Note at Maturity the Trustee (or any duly appointed Paying Agent) will pay the principal amount thereof, together with accrued interest through the date of redemption. Such payment shall be made in immediately available funds in U.S. dollars, provided that the Note is presented to the Trustee (or any such Paying Agent) in time for the Trustee (or such Paying Agent) to make payments in such funds in accordance with its normal procedures. The Company will provide the Trustee (and any such Paying Agent) with funds available for immediate use for such purpose. Notes presented at Maturity will be cancelled by the Trustee as provided in the Indenture. PROCEDURES FOR ESTABLISHING THE TERMS OF THE NOTES The Company and the Agent will discuss from time to time the rates to be borne by the Notes that may be sold as a result of the solicitation of offers by the Agent. Once the Agent has recorded any indication of interest in Notes upon certain terms, and communicated with the Company, if the Company accepts an offer to purchase Notes upon such terms, it will prepare a Pricing Supplement in the form previously approved by the Agent, reflecting the terms of such Notes and, after approval from the Agent, will arrange to have such Pricing Supplement (together with the Prospectus, if amended or supplemented) filed with the Commission and will supply an appropriate number of copies of the Prospectus, as then amended or supplemented, together with such Pricing Supplement, to the Agent. See "Delivery of Prospectus." No settlements with respect to Notes upon such terms may occur prior to such filing and the Agent will not, prior to such filing, mail confirmations to customers who have offered to purchase Notes upon such terms. After such filing, sales, mailing of confirmations and settlements may occur with respect to Notes upon such terms, subject to the provisions of "Delivery of Prospectus" below. If the Company decides to post rates and a decision has been reached to change interest rates, the Company will promptly notify the Agent. The Agent will forthwith suspend solicitation of purchases. At that time, the Agent will recommend and the Company will establish rates to be so "posted." Following establishment of posted rates and prior to the filing described in the following sentence, the Agent may only record indications of interest in purchasing Notes at the posted rates. Once the Agent has recorded any indication of interest in Notes at the posted rates and communicated with the Company, if the Company plans to accept an offer at the posted rate, it will prepare a Pricing Supplement reflecting such posted rates and, after approval from the Agent, will arrange to have such Pricing Supplement (together with the Prospectus if amended or supplemented) filed with the Commission and will supply an appropriate number of copies of the Prospectus, as then amended or supplemented, to the Agent. See "Delivery of Prospectus." No settlements at the posted rates may occur prior to such filing and the Agent will not, prior to such filing, mail confirmations to customers who have offered to purchase Notes at the posted rates. After such filing, sales, mailing of confirmations and settlements may resume, subject to the provisions of "Delivery of Prospectus" below. SUSPENSION OF SOLICITATION; AMENDMENT OR SUPPLEMENT In the event that at the time the Agent, at the direction of the Company, suspends solicitation of offers to purchase from the Company there shall be any orders outstanding which have not been settled, the Company will promptly advise the Agent and the Trustee whether such orders may be settled and whether copies of the Prospectus as theretofore amended and/or supplemented as in effect at the time of the suspension may be delivered in connection with the settlement of such orders. The Company will have the sole responsibility for such decision and for any arrangements which may be made in the event that the Company determines that such orders may not be settled or that copies of such Prospectus may not be so delivered. 35 B-7 DELIVERY OF PROSPECTUS A copy of the Prospectus as most recently amended or supplemented on the date of delivery thereof, together with the applicable Pricing Supplement, must be delivered to a purchaser prior to or together with the earlier of the delivery of (i) the written confirmation of a sale sent to a purchaser or his agent and (ii) any Note purchased by such purchaser.

DENOMINATIONS The authorized denominations for Multi-Currency Notes will be set forth in the applicable Pricing Supplement. CURRENCIES Unless otherwise specified in the applicable Pricing Supplement, purchasers of Multi-Currency Notes are required to pay for such Multi- Currency Notes in the Specified Currency in immediately available funds. If requested by the purchaser of the Multi-Currency Note on or prior to the fifth Business Day preceding the date of delivery of the Multi-Currency Notes (or by such other day as the Presenting Agent shall determine), the Presenting Agent will arrange the conversion of U.S. dollars into such Specified Currency to enable the purchaser to pay for the Multi-Currency Notes. Each such conversion will be made by the Presenting Agent on such terms and subject to such conditions, limitations and charges as such Presenting Agent may from time to time establish in accordance with its regular foreign exchange practices. All costs of exchange will be borne by the purchasers of the Multi-Currency Notes. PAYMENT OF PRINCIPAL AND INTEREST The principal of, premium, if any, and interest on Multi-Currency Notes will be payable in the Specified Currency. Unless otherwise indicated in the applicable Pricing Supplement, the agent appointed by the Company (the "Exchange Rate Agent") will convert all such payments of principal, premium, if any, and interest to U.S. dollars. However, unless otherwise indicated in the applicable Pricing Supplement, the holder of a Multi-Currency Note may elect to receive such payments in the Specified Currency as described below. Any U.S. dollar amount to be received by a holder of a Multi-Currency Note will be based on the highest bid quotation in The City of New York received by the Exchange Rate Agent at approximately 11:00 A.M., New York City time, on the second Business Day preceding the applicable payment date from three recognized foreign exchange dealers (one of which may be the Exchange Rate Agent) for the purchase by the quoting dealer of the Specified Currency for U.S. dollars for settlement on such payment date in the aggregate amount of the Specified Currency payable to all holders of Notes scheduled to receive U.S. dollar payments and at which the applicable dealer commits to execute a contract. If such bid quotations are not available, payments will be made in the Specified Currency. All currency exchange costs will be borne by the holder of the Multi-Currency Note by deductions from such payments. A holder of a Multi-Currency Note may, unless otherwise specified in the applicable Pricing Supplement, elect to receive payment of the principal of, premium, if any, and interest on such Multi-Currency Notes in the Specified Currency, by transmitting a written request for such payment by mail, hand delivered, or by cable, telex or other form of facsimile transmission to the principal office of the Trustee (acting as the Company's paying agent in The City of New York) on or prior to the Record Date or at least sixteen days prior to Maturity, as the case may be, such election to remain in effect until revoked by written notice to the Trustee received by the Trustee on or prior to the Record 37 B-9 Date or at least sixteen days prior to Maturity, as the case may be. A holder of a Multi-Currency Note may elect to receive payment in the Specified Currency for all principal, premium, if any, and interest payments and need not file a separate election for each payment. Interest on Multi-Currency Notes paid in U.S. dollars will be paid in the manner specified in the applicable Pricing Supplement. Unless otherwise specified in the applicable Pricing Supplement, interest on Multi-Currency Notes paid in the Specified Currency will be paid by wire transfer to a bank account maintained by the holder in the country of the Specified Currency. The principal of Multi-Currency Notes, together with interest accrued and unpaid therein, due at Maturity will be paid in immediately available funds against presentation of such Multi-Currency Notes at the principal office of the Trustee, provided that principal, premium, if any, and interest payable at Maturity in a Specified Currency will be paid by wire transfer to such bank account. Any payment of principal or interest required to be made on an Interest Payment Date or at Maturity of a Multi-Currency Note which is not a Business Day need not be made on such day, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or Maturity, as the case may be, and no interest shall accrue from the period from and after such Interest Payment Date or Maturity. PAYMENT CURRENCY If a Specified Currency is not available for payment of principal or interest with respect to a Multi-Currency Note due to the imposition of exchange controls or other circumstances beyond the reasonable control of the Company, the Company will be entitled to satisfy its obligations to holders of Multi-Currency Notes by making such payment in U.S. dollars on the basis of the noon buying rate in The City of New York for cable transfers of the Specified Currency as certified for customs purposes by the Federal Reserve Bank of New York (the "Market Exchange Rate") on the second day prior to such payment, or if such Market Exchange Rate is not then available, on the basis of the most recently available Market Exchange Rate or as otherwise indicated in the applicable Pricing Supplement. Any payment made under such circumstances in U.S. dollars where required payment is in a Specified Currency will not constitute a default under the Indenture. OUTSTANDING MULTI-CURRENCY NOTES For purposes of calculating the principal amount of any Multi-Currency Note for any purpose under the Indenture, the principal amount of such Multi-Currency Note at any time Outstanding shall be deemed to be the U.S. dollar equivalent at the Market Exchange Rate, determined as of the date of the original issuance of such Multi-Currency Note, of the principal amount of such Multi-Currency Note. DETAILS FOR SETTLEMENT OF MULTI-CURRENCY NOTES In addition to the Settlement information specified in "Settlement Procedures" above, the Presenting Agent shall communicate to the Company in the manner set forth in "Settlement Procedures" the following information: 1. Specified Currency 2. Denominations 3. Wire transfer and overseas bank account information (if holder has elected payment in a Specified Currency). 38 B-10 SPECIAL ADMINISTRATIVE PROCEDURES FOR BOOK-ENTRY NOTES Each Note will be represented by either a Global Security delivered to the Trustee, as agent for the Depository Trust Company ("DTC"), and recorded in the book-entry system maintained by DTC or a certificate delivered to the Holder thereof or a Person designated by such Holder. An owner of a Book-Entry Note will not be entitled to receive a certificate representing such Note. In connection with the qualification of the Book-Entry Notes for eligibility in the book-entry system maintained by DTC, the Trustee will perform the custodial, document control and administrative functions described below, in accordance with its respective obligations under a Letter of Representations from the Company and the Trustee to DTC and a Medium-Term Note Certificate Agreement previously entered into between the Trustee and DTC, and its obligations as a participant in DTC, including DTC's Same-Day Funds Settlement System ("SDFS"). Except as otherwise set forth in this Exhibit B, Book-Entry Notes will be issued in accordance with the administrative procedures set forth below. ISSUANCE On any date of settlement (as defined under "Settlement" below) of one or more Fixed Rate Book-Entry Notes, the Company will issue a single Global Security in fully registered form without coupons representing the principal amount of all of such Notes that have the same original issuance date, interest rate and Stated Maturity. Similarly, on any settlement date for one or more Floating Rate Book-Entry Notes, the Company will issue a single Global Security representing the principal amount of all of such Notes that have the same interest rate formula, original issuance date, Initial Interest Rate, Interest Payment Dates, Index Maturity, Spread, Spread Multiplier, minimum interest rate (if any), maximum interest rate (if any) and Stated Maturity. Each Global Security will be dated and issued as of the date of its authentication by the Trustee. Each Global Security will have an interest accrual date (the "Interest Accrual Date"), which will be (i) with respect to an original Global Security (or any portion thereof), its original issuance date and (ii) with respect to any Global Security (or portion thereof) issued subsequently upon exchange of a Global Security or in lieu of a destroyed, lost or stolen Global Security, the most recent Interest Payment Date to which interest has been paid or duly provided for on the predecessor Global Security or Securities (or if no such payment or provision has been made, the original issuance date of the predecessor Global Security), regardless of the date of authentication of such subsequently issued Global Security. No Global Security will represent (i) both Fixed Rate and Floating Rate Book-Entry Notes or (ii) any Certificated Note or (iii) any Multi-Currency or Indexed Note. IDENTIFICATION NUMBERS The Company will arrange, on or prior to commencement of a program for the offering of Book-Entry Notes, with the CUSIP Service Bureau of Standard & Poor's Corporation (the "CUSIP Service Bureau") for the reservation of a series of CUSIP numbers (including tranche numbers), consisting of approximately 900 CUSIP numbers and relating to Global Securities representing the Book-Entry Notes. The Trustee has or will obtain from the CUSIP Service Bureau a written list of such series of reserved CUSIP numbers and will deliver to the Company and DTC such written list of 900 CUSIP numbers of such series. The Company will assign CUSIP numbers to Global Securities as described below under Settlement Procedure "B." DTC will notify the CUSIP Service Bureau periodically of the CUSIP numbers that the Company has assigned to Global Securities. The Trustee will notify the Company at any time when fewer than 100 of the reserved CUSIP numbers remain unassigned to Global Securities, and if it deems necessary, the Company will reserve additional CUSIP numbers for assignment to Global Securities representing Book- Entry Notes. Upon obtaining such additional CUSIP numbers the Trustee shall deliver such additional CUSIP numbers to the Company and DTC. 39 B-11 REGISTRATION Each Global Security will be registered in the name of Cede & Co., as nominee for DTC, on the Securities Register maintained under the Indenture governing such Global Security. The beneficial owner of a Book-Entry Note (or one or more indirect participants in DTC designated by such owner) will designate one or more participants in DTC (with respect to such Note, the "Participants") to act as agent or agents for such owner in connection with the book-entry system maintained by DTC, and DTC will record in book-entry form, in accordance with instructions provided by such Participants, a credit balance with respect to such Note in the account of such Participants. The ownership interest of such beneficial owner in such Note will be recorded through the records of such Participants or through the separate records of such Participants and one or more indirect participants in DTC. TRANSFERS Transfers of a Book-Entry Note will be accomplished by book entries made by DTC and, in turn, by Participants (and in certain cases, one or more indirect participants in DTC) acting on behalf of beneficial transferors and transferees of such Note. CONSOLIDATION AND EXCHANGE The Trustee may deliver to DTC and the CUSIP Service Bureau at any time a written notice of consolidation specifying (i) the CUSIP numbers of two or more Outstanding Global Securities that represent (A) Fixed Rate Book-Entry Notes having the same original issuance date, interest rate and Stated Maturity and with respect to which interest has been paid to the same date or (B) Floating Rate Book-Entry Notes having the same interest rate formula, original issuance date, Initial Interest Rate, Interest Payment Dates, Index Maturity, Spread or Spread Multiplier, minimum interest rate (if any), maximum interest rate (if any) and with respect to which interest has been paid to the same date, (ii) a date, occurring at least thirty days after such written notice is delivered and at least thirty days before the next Interest Payment Date for such Book-Entry Notes, on which such Global Securities shall be exchanged for a single replacement Global Security and (iii) a new CUSIP number, obtained from the Company, to be assigned to such replacement Global Security. Upon receipt of such a notice, DTC will send to its participants (including the Trustee) a written reorganization notice to the effect that such exchange will occur on such date. Prior to the specified exchange date, the Trustee will deliver to the CUSIP Service Bureau a written notice setting forth such exchange date and the new CUSIP number and stating that, as of such exchange date, the CUSIP numbers of the Global Securities to be exchanged will no longer be valid. On the specified exchange date, the Trustee will exchange such Global Securities for a single Global Security bearing the new CUSIP number and a new Interest Accrual Date, and the CUSIP numbers of the exchanged Global Securities will, in accordance with CUSIP Service Bureau procedures, be cancelled and not immediately reassigned. Notwithstanding the foregoing, if the Global Securities to be exchanged exceed $200,000,000 in aggregate principal amount, one Global Security will be authenticated and issued to represent each $200,000,000 of principal amount of the exchanged Global Securities and an additional Global Security will be authenticated and issued to represent any remaining principal amount of such Global Securities (see "Denominations" below). MATURITIES Each Book-Entry Note will mature on a date not less than nine months after the settlement date for such Note. A Floating Rate Book- Entry Note will mature only on an Interest Payment Date for such Note. 40 B-12 DENOMINATIONS Book-Entry Notes will be issued in principal amounts of $1,000 or any amount in excess thereof that is an integral multiple of $1,000. Global Securities representing one or more Book-Entry Notes will be denominated in principal amounts not in excess of $200,000,000. If one or more Book-Entry Notes having an aggregate principal amount in excess of $200,000,000 would, but for the preceding sentence, be represented by a single Global Security, then one Global Security will be issued to represent each $200,000,000 principal amount of such Book-Entry Note or Notes and an additional Global Security will be issued to represent any remaining principal amount of such Book-Entry Note or Notes. In such a case, each of the Global Securities representing such Book-Entry Note or Notes shall be assigned the same CUSIP number. INTEREST General. Interest on each Book-Entry Note will accrue from the Interest Accrual Date of the Global Security representing such Note. Each payment of interest on a Book-Entry Note will include interest accrued through the day preceding, as the case may be, the Interest Payment Date or Maturity; provided, however, that if the Interest Reset Dates with respect to any such Note are daily or weekly, interest payable on any Interest Payment Date, other than interest payable on any date on which principal for such Note is payable, will include interest accrued from but excluding the second preceding Regular Record Date to and including the next preceding Regular Record Date. Interest payable at the Maturity of a Book-Entry Note will be payable to the Person to whom the principal of such Note is payable. Standard & Poor's Corporation will use the information received in the pending deposit message described under Settlement Procedure "C" below in order to include the amount of any interest payable and certain other information regarding the related Global Security in the appropriate weekly bond report published by Standard & Poor's Corporation. On the first Business Day of January, April, July and October of each year, the Trustee will deliver to the Company and DTC a written list of Regular Record Dates and Interest Payment Dates that will occur with respect to Floating Rate Book-Entry Notes during the six-month period beginning on such first Business Day.
