DESCRIPTION OF DEBT SECURITIES

    The following describes some of the general terms and provisions of the indenture dated as of August 29, 2000, between us and U.S. Bank Trust National Association, as trustee, which, together with any other trustee(s) appointed with respect to a particular series of debt securities, we refer to as the "trustee." The particular terms of the debt securities will be set forth in a prospectus supplement relating to such debt securities and in the applicable form of note.

    The indenture has been filed as an exhibit to the registration statement of which this prospectus is a part and is available for inspection at the corporate trust office of the trustee, or as described below under "Where You Can Find More Information" beginning on page 2 of this prospectus. The indenture is subject to, and governed by, the Trust Indenture Act of 1939, as amended. The statements made in this prospectus relating to the indenture and the debt securities to be issued under the indenture are summaries of some, but not all, of the provisions of the indenture and the debt securities and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all provisions of the indenture and such debt securities. Unless otherwise specified, all section references appearing in this summary are to sections of the indenture.

General

    The debt securities will be direct, unsecured obligations of EOP Partnership and will rank equally with all other unsecured and unsubordinated indebtedness of EOP Partnership. Unless otherwise specified in the applicable prospectus supplement, Equity Office has no obligation for payment of principal of or interest on the debt securities. The debt securities may be issued in one or more series, in each case as established from time to time in or pursuant to authority granted by a resolution of the Equity Office board of trustees, as general partner of EOP Partnership, or as established in the indenture or in one or more indentures supplemental to the indenture. All debt securities of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the holders of the debt securities of such series, for issuances of additional debt securities of such series (Section 301).

    The indenture provides that there may be more than one trustee, each with respect to one or more series of debt securities. Any trustee under the indenture may resign or be removed with respect to one or more series of debt securities, and a successor trustee may be appointed to act with respect

4


to such series (Section 608). If two or more persons are acting as trustee with respect to different series of debt securities, each such trustee shall be a trustee of a trust under the applicable indenture separate and apart from the trust administered by any other trustee (Section 609), and, except as otherwise indicated herein, any action described herein to be taken by the trustee may be taken by each such trustee with respect to, and only with respect to, the one or more series of debt securities for which it is trustee under the indenture.

    Reference is made to the prospectus supplement relating to the series of debt securities being offered for the specific terms thereof, including:

5


    The debt securities may provide for less than the entire principal amount thereof to be payable upon declaration of acceleration of the maturity thereof. Special United States federal income tax, accounting and other considerations applicable to any such original issue discount securities will be described in the applicable prospectus supplement.

    Reference is made to the applicable prospectus supplement for information with respect to any additions to, modifications of or deletions from the events of default or covenants set forth in the indenture, including any addition of any covenant or other provision granting special rights upon the occurrence of specified events to the holders of a particular series of debt securities.

6


Denominations, Interest, Registration and Transfer

    Unless otherwise described in the applicable prospectus supplement, the debt securities of any series will be issuable in denominations of $1,000 and integral multiples thereof (Section 302).

    Unless otherwise specified in the applicable prospectus supplement, the principal of, and premium, if any, and interest on any series of debt securities will be payable at the corporate trust office of the trustee, initially located at 100 Wall Street, Corporate Trust Office, 16th floor, New York, New York 10005; provided that, at our option, payment of interest may be made by check mailed to the address of the person entitled thereto as it appears in the security register or by wire transfer of funds to such person at an account maintained within the United States (Sections 301, 305, 306, 307 and 1002).

    Unless otherwise specified with respect to a particular series of debt securities, any interest not punctually paid or duly provided for on any interest payment date with respect to a debt security will cease to be payable to the holder on the applicable regular record date and, at our election, may either be paid to the person in whose name such debt security is registered at the close of business on a special record date for the payment of such defaulted interest to be fixed by the trustee, or may be paid at any time in any other lawful manner, all as more completely described in the indenture. Notice of the fixing of any special record date for the payment of defaulted interest is required to be given to the holders of the affected debt securities not less than 10 days prior to such special record date. (Section 307).

    Subject to limitations imposed upon debt securities issued in book-entry form, the debt securities of any series will be exchangeable for other debt securities of the same series and of a like aggregate principal amount and tenor of different authorized denominations upon surrender of such debt securities at the corporate trust office of the trustee referred to above. In addition, subject to limitations imposed upon debt securities issued in book-entry form, the debt securities of any series may be surrendered for registration of transfer or exchange thereof at the corporate trust office of the trustee. Every debt security surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer. No service charge will be made for any registration of transfer or exchange of any debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (Section 305). If the applicable prospectus supplement refers to any transfer agent, in addition to the trustee, initially designated by us with respect to any series of debt securities, we may at any time rescind the designation of any such transfer agent or approve a change in the location through which any such transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for such series. We may at any time designate additional transfer agents with respect to any series of debt securities (Section 1002).

    Neither we nor the trustee under the indenture are required to:

    Maintenance of Properties.  We are required to cause all of our material properties used or useful in the conduct of our business or the business of any of our Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and to cause to be made all necessary repairs, renewals, replacements, betterments and improvements, all as in our reasonable judgment may be necessary so that our business may be properly and advantageously conducted at all times; provided, however, that we and our Subsidiaries may not be prevented from discontinuing the operation and maintenance of any of the properties if such discontinuance is, in our judgment, desirable in the conduct of our business and not disadvantageous in any material respect to the holders of our debt securities (Section 1007).

We will also in any event:

    We may consolidate with, or sell, lease or convey all or substantially all of our assets to, or merge with or into, any other corporation, limited liability company, association, partnership, real estate investment trust, company or business trust, provided that:

12


Events of Default, Notice and Waiver

    The following events are "events of default" with respect to the debt securities of a series:

    If an event of default under the indenture occurs and is continuing, then in every such case the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of the series in default may declare the principal amount of all of the debt securities of such series to be due and payable immediately by written notice thereof to EOP Partnership, and to the trustee if given by the holders. However, at any time after such a declaration of acceleration with respect to such debt securities has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of not less than a majority in principal amount of such outstanding debt securities may rescind and annul such declaration and its consequences if:

    The indenture also provides that the holders of not less than a majority in principal amount of the outstanding debt securities of a series may waive any past default with respect to such series and its consequences, except a default:

13


    The trustee will be required to give notice to the holder of debt securities within 90 days of a default under the indenture unless such default has been cured or waived; provided, however, that the trustee may withhold notice to the holders of any default (except a default in the payment of the principal of, or premium or Make-Whole Amount, if any, or interest on any debt securities or any additional amounts with respect to any debt security of such series or in the payment of any sinking fund installment in respect of any debt securities) if specified responsible officers of the trustee consider such withholding to be in the interest of such holders (Section 601).

    The indenture provides that no holder of debt securities or related coupon may institute any proceedings, judicial or otherwise, with respect to the indenture or for the appointment of a receiver or trustee, or for any remedy thereunder, except in the case of failure of the trustee, for 60 days, to act after it has received a written request to institute proceedings in respect of an event of default from the holders of not less than 25% in principal amount of the outstanding debt securities of a series, as well as an offer of indemnity reasonably satisfactory to it (Section 507). This provision will not prevent, however, any holder of debt securities from instituting suit for the enforcement of payment of the principal of, and premium or Make-Whole Amount, if any, and interest on, and any additional amounts in respect of, such debt securities at the respective due dates thereof (Section 508).

    Subject to the provisions in the indenture relating to its duties in case of default, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any holders of any debt securities then outstanding under the indenture, unless such holders shall have offered to the trustee thereunder reasonable security or indemnity (Section 602). The holders of not less than a majority in principal amount of the outstanding debt securities of a series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee in respect of such debt securities, or of exercising any trust or power conferred upon the trustee in respect of such debt securities and related coupons. However, the trustee may refuse to follow any direction which is in conflict with any law or the indenture, which may involve the trustee in personal liability or which may be unduly prejudicial to the holders of debt securities of such series not joining therein, but may take any other action deemed proper by the trustee which is not inconsistent with such direction. (Section 512).

    Within 120 days after the close of each fiscal year, we must deliver to the trustee a certificate, signed by one of several specified officers of Equity Office, our general partner, stating whether or not such officer has knowledge of any default under the indenture and, if so, specifying each such default and the nature and status thereof (Section 1011).

Modification of the Indenture

    Modifications and amendments of the indenture will be permitted to be made only with the consent of the holders of not less than a majority in principal amount of all outstanding debt securities of each series which is affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the holders of each such debt security affected thereby:

14


    A debt security shall be deemed outstanding if it has been authenticated and delivered under the indenture unless, among other things, such debt security has been canceled or redeemed.

    The indenture provides that the holders of not less than a majority in principal amount of outstanding debt securities of a series have the right to waive compliance by EOP Partnership with specified covenants in the indenture in respect of such debt securities (Section 1013). Compliance with the covenants described herein and such additional covenants with respect to the debt securities of a series generally may not be waived by the Equity Office board of trustees, as our general partner, or by the trustee.

    Modifications and amendments of the indenture will be permitted to be made by us and the trustee without the consent of any holder for any of the following purposes:

    The indenture contains provisions for convening meetings of the holders of debt securities (Section 1501). A meeting will be permitted to be called at any time by the trustee, and also, upon request, by EOP Partnership or the holders of at least 10% in principal amount of the outstanding debt securities, in any such case upon notice given as provided in the indenture (Section 1502). Except for any consent that must be given by the holder of each debt security affected by specified modifications and amendments of the indenture, any resolution presented at a meeting or adjourned meeting duly reconvened at which a quorum is present will be permitted to be adopted by the affirmative vote of the holders of a majority in aggregate principal amount of the outstanding debt securities represented at that meeting; provided, however, that, except as referred to above, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that may be made, given or taken by the holders of a specified percentage, which is less than a majority, in principal amount of the outstanding debt securities of a series may be adopted at a meeting or adjourned meeting duly reconvened at which a quorum is present by the affirmative vote of the holders of such specified percentage in principal amount of the outstanding debt securities of that series. Any resolution passed or decision taken at any meeting of holders of debt securities duly held in accordance with the indenture will be binding on all holders of debt securities of such series, whether or not present or represented at the meeting. The quorum at any meeting called to adopt a resolution, and at any reconvened meeting, will be persons holding or representing a majority in principal amount of the outstanding debt securities; provided, however, that if any action is to be taken at such meeting with respect to a consent or waiver which may be given by the holders of not less than a specified percentage in principal amount of the outstanding debt securities of a series, the persons holding or representing such specified percentage in principal amount of the outstanding debt securities of such series will constitute a quorum (Section 1504).

    Notwithstanding the foregoing provisions, if any action is to be taken at a meeting of holders of debt securities of any series with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that the indenture expressly provides may be made, given or taken by the holders of a specified percentage in principal amount of all outstanding debt securities affected thereby, or of the holders of such series and one or more additional series:

Satisfaction and Discharge

    We may discharge specified obligations to holders of debt securities that have not already been delivered to the trustee for cancellation and that either have become due and payable or will become

16


due and payable within one year, or scheduled for redemption within one year, by irrevocably depositing with the trustee, in trust, funds in such currency or currencies, currency unit or units or composite currency or currencies in which such debt securities are payable in an amount sufficient to pay the entire indebtedness on such debt securities in respect of principal, and premium or Make-Whole Amount, if any, and interest, and any additional amounts with respect thereto, to the date of such deposit, if such debt securities have become due and payable, or to the stated maturity or redemption date, as the case may be (Section 401).

Global Securities

    If the applicable prospectus supplement so indicates, the debt securities will be evidenced by one or more global securities, which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, or DTC, and registered in the name of Cede & Co., as DTC's nominee.

    Holders may hold their interests in any of the global securities directly through DTC, or indirectly through organizations which are participants in DTC. Transfers between participants will be effected in the ordinary way in accordance with DTC rules and will be settled in immediately available funds.

    Holders who are not DTC participants may beneficially own interests in a global security held by DTC only through participants, including some banks, brokers, dealers, trust companies and other parties that clear through or maintain a custodial relationship with a participant, either directly or indirectly, and have indirect access to the DTC system. So long as Cede & Co., as the nominee of DTC, is the registered owner of any global security, Cede for all purposes will be considered the sole holder of such global security. Except as provided below, owners of beneficial interests in a global security will not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form, and will not be considered the holders thereof.

    Neither we nor the trustee, nor any registrar or paying agent, will have any responsibility for the performance by DTC or their participants or indirect participants of their respective obligations under the rules and procedures governing their operations. DTC has advised EOP Partnership that it will take any action permitted to be taken by a holder of debt securities only at the direction of one or more participants whose accounts are credited with DTC interests in a global security.

    DTC has advised us as follows:

    Purchases of debt securities under the DTC system must be made by or through participants, which will receive a credit for the debt securities on DTC's records. The ownership interest of each actual purchaser of each debt security is in turn to be recorded on the participant's and indirect

17


participants' records. Purchasers will not receive written confirmation from DTC of their purchase, but purchasers are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participant or indirect participant through which the purchasers entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of participants and indirect participants acting on behalf of actual purchasers. Purchasers of debt securities will not receive certificates representing their ownership interests, except if the use of the book-entry system for the debt securities is discontinued.

    The deposit of debt securities with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities. DTC's records reflect only the identity of the participants whose accounts such debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

    The laws of some jurisdictions require that some purchasers of securities take physical delivery of securities in definitive form. Such laws may impair the ability to transfer beneficial interests in the global security.

    Redemption notices shall be sent to Cede & Co. If less than all of the principal amount of the global securities of the same series is being redeemed, DTC's practice is to determine by lot the amount of the interest of each participant therein to be redeemed.

    Conveyance of notices and other communications by DTC to participants, by participants to indirect participants and by participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements that may be in effect from time to time.

    Principal, Make-Whole Amount and interest payments on the debt securities will be made to Cede & Co. by wire transfer of immediately available funds. DTC's practice is to credit participants' accounts on the payable date in accordance with their respective holdings shown on DTC's records unless DTC has reason to believe that it will not receive payment on the payment date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such participant and not of DTC or EOP Partnership, subject to any statutory or regulation requirements as may be in effect from time to time. Payments of principal, Make-Whole Amount and interest to Cede & Co. is our responsibility, disbursement of such payments to participants is the responsibility of DTC, and disbursement of such payments to the beneficial owners of the debt securities is the responsibility of participants and indirect participants. Neither EOP Partnership nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

    DTC may discontinue providing its services as securities depository with respect to the debt securities at any time by giving us reasonable notice. Under such circumstances, in the event that a successor securities depository is not obtained, certificates for the relevant notes will be printed and delivered in exchange for interests in such global security. Any global security that is exchangeable pursuant to the preceding sentence shall be exchangeable for relevant debt securities in authorized denominations registered in such names as DTC shall direct. It is expected that such instruction will be based upon directions received by DTC from its participants with respect to ownership of beneficial interests in such global security.

    We may decide to discontinue use of the system of book-entry transfers through DTC, or a successor securities depository. In that event, certificates representing the debt securities will be printed and delivered.

    The information in this section concerning DTC and DTC's book-entry system has been obtained from sources that we believe to be reliable, but we do not take responsibility for the accuracy thereof.


DESCRIPTION OF WARRANTS

    We may issue warrants for the purchase of debt securities. Warrants may be issued independently or together with any other debt securities offered by any prospectus supplement and may be attached to or separate from such debt securities. Each series of warrants will be issued under a separate warrant agreement, each, a warrant agreement, to be entered into between the EOP Partnership and a warrant agent specified in the applicable prospectus supplement. The warrant agent will act solely as our agent of in connection with the warrants of such series and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. The following sets forth some general terms and provisions of the warrants offered hereby. Further terms of the warrants and the applicable warrant agreements will be set forth in the applicable prospectus supplement.

PLAN OF DISTRIBUTION

    We may sell the securities to one or more underwriters for public offering and sale by them or may sell the securities to investors directly or through agents. Any such underwriter or agent involved in the offer and sale of the securities will be named in the applicable prospectus supplement.

    We may offer and sell the securities at a fixed price or prices, which may be changed, at prices related to the prevailing market prices at the time of sale or at negotiated prices for cash or assets in transactions that do not constitute a business combination within the meaning of Rule 145 promulgated under the Securities Act. We also may offer and sell debt securities upon the exercise of warrants. We also may, from time to time, authorize underwriters acting as our agents to offer and sell the securities upon the terms and conditions as are set forth in the applicable prospectus supplement. In connection with the sale of the securities, underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of the securities for whom they may act as agent. Underwriters may sell securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers from whom they may act as agent.

    Any underwriting compensation paid by us to underwriters or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be set forth in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions, under the Securities Act. Underwriters, dealers and agents may be entitled, under agreements entered into with us, to indemnification against and contribution toward specified civil liabilities, including liabilities under the Securities Act of 1933, as amended.

    If so indicated in the applicable prospectus supplement, we will authorize dealers acting as our agents to solicit offers by specified institutions to purchase securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts, or contracts, providing for payment and delivery on the date or dates stated in such prospectus supplement. Each such contract will be for an amount not less than, and the aggregate principal amount of securities sold pursuant to such contracts shall be not less nor more than, the respective amounts stated in the applicable prospectus supplement. Institutions with whom such contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions, and other institutions but will in all cases be subject to our approval. Such contracts will not be subject to any conditions except:

    Some of the underwriters and their affiliates may engage in transactions with and perform services for us and our subsidiaries in the ordinary course of business.

Item 15.  Indemnification of Trustees and Officers

    Pursuant to its Second Amended and Restated Agreement of Limited Partnership, EOP Partnership is obligated to indemnify, to the fullest extent provided by law, any person or entity made a party to a proceeding by reason of its status as a general partner, a limited partner or a trustee, director or officer of EOP Partnership or any general partner and such other persons or entities as Equity Office may designate from time to time in its sole discretion (an "Indemnitee") from and against any and all losses, claims, damages, liabilities, joint or several, expenses, including attorneys' fees and other legal fees and expenses, judgments, fines, settlements and other amounts arising from or in connection with any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, incurred by the Indemnitee and relating to EOP Partnership or the general partners or the operation of, or the ownership of property by, any of them as set forth in the Partnership Agreement in which any such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, unless it is established by a final determination of a court of competent jurisdiction that: (a) the act or omission of the Indemnitee was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty, (b) the Indemnitee actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the Indemnitee had reasonable cause to believe that the act or omission was unlawful. Any indemnification shall be made only out of the assets of EOP Partnership, and any insurance proceeds from the liability policy covering the general partners and any Indemnitee, and neither a general partner nor any limited partner shall have any obligation to contribute to the capital of EOP Partnership or otherwise provide funds to enable EOP Partnership to fund its indemnity obligations. EOP Partnership is obligated to advance amounts to an Indemnitee for expenses upon receipt of (a) a written affirmation of the Indemnitee that it believes it has met the standard of conduct necessary to entitle it to indemnification and (b) a written undertaking of the Indemnitee that it will repay any such advances if it shall be ultimately determined that it did not meet such standard of conduct. The foregoing indemnification rights are in addition to any other rights afforded to an Indemnitee under any other agreement, by vote of the partners, under applicable law or otherwise, and shall continue as to an Indemnitee who has ceased to serve in such capacity unless otherwise provided in a written agreement pursuant to which such Indemnitees are indemnified. EOP Partnership is authorized to purchase and maintain insurance on behalf of the Indemnitees with respect to the foregoing matters. EOP Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to EOP Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute fines; and actions taken or omitted by the Indemnitee

II-1


with respect to an employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the interests of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is not opposed to the best interests of EOP Partnership. An Indemnitee shall not be denied indemnification in whole or in part because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of the Partnership Agreement.

Item 17.  Undertakings

(a)
The undersigned registrant hereby undertakes:

(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)
To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in this registration statement;

provided, however, that subparagraphs (i) and (ii) above shall not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in the periodic reports

II-2


filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement.

(b)
The undersigned registrant hereby further undertakes that, for the purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the Securities offered herein, and the offering of such Securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to existing provisions or arrangements whereby the registrant may indemnify a director, officer or controlling person of the registrant against liabilities arising under the Securities Act of 1933, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
