Without unnecessary delay but, in any event, not later than the Exchange Date, the Company shall deliver to the Principal Paying Agent the Permanent Global Note. Upon the first occurrence of the events specified in paragraphs (i) and (ii) above, the Principal Paying Agent shall authenticate and deliver to the Common Depositary, in exchange for the portion of the Temporary Global Note being surrendered, the Permanent Global Note, in a principal amount equal to the aggregate principal amount of the Temporary Global Note so surrendered. The Principal Paying Agent shall endorse the Temporary Global Note to reflect a reduction in the principal amount equal to the principal amount thereupon represented by the Permanent Global Note and shall, after such endorsement, redeliver the Temporary Global Note to the Common Depositary. Upon any subsequent occurrence of the events specified in paragraph (i) and (ii) above, and upon surrender to the Principal Paying Agent of the Temporary Global Note to be exchanged and the Permanent Global Note, the Principal Paying Agent shall endorse the Temporary Global Note to reflect a reduction in the principal amount equal to the portion to be exchanged, and the Principal Paying Agent shall endorse the Permanent Global Note so as to increase the principal amount thereof by an amount equal to the portion being exchanged and shall thereupon redeliver the Permanent Global Note and the Temporary Global Note to the Common Depositary. At such time as the principal amount of the Temporary Global Note shall have been reduced to zero, the Trustee shall cancel the Temporary Global Note in accordance with Section 2.15 of the Supplemental Indenture. In each of the foregoing cases, the Euroclear Operator or Cedel Bank, as the case may be, shall then credit the portion of the Permanent Global Note being exchanged to the respective accounts of the beneficial owners of the portion of the Temporary Global Note so surrendered (or to such other accounts as such beneficial owners may direct). 5 SECTION 3.04. Exchange of Permanent Global Note for Definitive Notes. The beneficial owner of an interest in the Permanent Global Note is entitled to exchange such interest for Notes in definitive bearer form, serially numbered, with interest coupons ("Coupons") attached, substantially in the form set forth in Exhibit A-3 hereto ("Definitive Notes"), in denominations of U.S. $10,000 and in an aggregate principal amount equal to the amount of such beneficial interest, upon the occurrence of the following events: (i) the account holder having beneficial ownership of such interest instructs the Euroclear Operator or Cedel Bank, as the case may be, to request such exchange on its behalf and delivers to any Non-U.S. Paying Agent (which Non-U.S. Paying Agent shall deliver such request to the Trustee and the Company), through the Euroclear Operator or Cedel Bank, as the case may be, at least 30 days' written notice of such exchange, which notice specifies the number of Definitive Notes into which such interest shall be exchanged (each an "Exchange Request"); and (ii) on or after the earliest date on which such interests may be exchanged, the Common Depositary surrenders the Permanent Global Note to the Principal Paying Agent to be exchanged in whole for Definitive Notes. All (but not less than all) interests in the Permanent Global Note shall be so exchanged for one or more Definitive Notes (i) upon receipt by the Company of a copy of an Exchange Request from the first beneficial owner of an interest in the Permanent Global Note to make such an Exchange Request or (ii) upon receipt by the Principal Paying Agent and the Trustee of a notice from the Company stating that (x) the Permanent Global Note has been accelerated following an Event of Default or (y) the Euroclear Operator or Cedel Bank has been closed for business for a continuous period of fourteen days (other than by reason of public holidays) or has announced its intention to cease business permanently or in fact has done so. The Company shall, promptly upon delivery of any such notice to the Principal Paying Agent and the Trustee, cause the Common Depositary (i) to instruct the Principal Paying Agent and the Company regarding the aggregate principal amount of Definitive Notes that must be authenticated and delivered to each relevant clearing system in exchange for the Permanent Global Note and (ii) to surrender the Permanent Global Note to the Principal Paying Agent to be exchanged in whole for Definitive Notes. As soon as practicable after either (i) receiving a copy of an Exchange Request from a Non-U.S. Paying Agent or (ii) delivering to the Principal Paying 6 Agent and the Trustee such a notice of acceleration of the Permanent Global Note or of closure of a relevant clearing system, the Company shall deliver to the Principal Paying Agent Definitive Notes in authorized denominations equal in aggregate principal amount to the principal amount of the Permanent Global Note. Upon receiving an Exchange Notice or such a notice from the Company and the Permanent Global Note from the Common Depositary, the Principal Paying Agent shall authenticate and deliver to the Euroclear Operator or Cedel Bank, as the case may be, in exchange for each portion of the Permanent Global Note, such Definitive Notes. The Euroclear Operator or Cedel Bank, as the case may be, shall then deliver such Definitive Notes (A) in the case of an exchange initiated by an Exchange Request, (x) to the beneficial owner (or to such person as the beneficial owner may direct) of the portion of the Permanent Global Note with respect to which the Exchange Request was submitted and (y) to the Euroclear Operator and Cedel Bank, as the case may be, for the account of the beneficial owners of all remaining interests in the Permanent Global Note in accordance with their interests, or (B) in the case of an exchange following a notice of acceleration of the Permanent Global Note or of closure of a relevant clearing system, to the beneficial owners of all the interests in the Permanent Global Note in accordance with their interests. SECTION 3.05. No Exchange in Certain Circumstances.

The Closing Price of the Texaco Common Stock on any of the Trading Days used to calculate the Conversion Amount will be subject to adjustment by the Calculation Agent as described below to the extent that any of the events requiring such adjustment occurs during the period commencing on the date of this Note and ending on such Trading Day. Texaco Common Stock Dividends and Extraordinary Dividends and Distributions In the event that a dividend or other distribution is declared (i) on any class of Texaco capital stock, payable in shares of Texaco Common Stock, (ii) on the Texaco Common Stock payable in cash in an amount greater than 10% of the Closing Price of the Texaco Common Stock on the date fixed for the determination of the shareholders of Texaco entitled to receive such cash dividend (an "Extraordinary Cash Dividend"), or (iii) on the Texaco Common Stock of A-2-7 evidences of indebtedness or assets (including securities, but excluding any dividend or distribution covered by clause (i) or any Texaco Spin-off described under "-Dissolution of Texaco; Mergers, Consolidations or Sales of Assets; Spin-offs" below) (an "Extraordinary Distribution"), any Closing Price of the Texaco Common Stock used to calculate the Conversion Amount on any Trading Day that follows the date (the "Texaco Record Date") fixed for the determination of the shareholders of Texaco entitled to receive such dividend or other distribution shall be increased by multiplying such Closing Price by a fraction, the numerator of which shall be the number of shares of Texaco Common Stock outstanding on the Texaco Record Date plus the number of shares constituting such distribution or, in the case of any Extraordinary Cash Dividend or Extraordinary Distribution, plus the number of shares of Texaco Common Stock that could be purchased with the amount of such Extraordinary Cash Dividend or the fair market value (as determined by the Calculation Agent, whose determination shall be conclusive and binding) of the evidences of indebtedness or assets constituting such Extraordinary Distribution at the Closing Price on the Trading Day immediately subsequent to such Texaco Record Date, and the denominator of which shall be the number of shares of Texaco Common Stock outstanding on the Texaco Record Date. Subdivisions and Combinations of the Texaco Common Stock In the event that the outstanding shares of Texaco Common Stock are subdivided into a greater number of shares, the Closing Price of the Texaco Common Stock used to calculate the Conversion Amount on any Trading Day that follows the date on which such subdivision becomes effective will be proportionately increased and, conversely, in the event that the outstanding shares of Texaco Common Stock are combined into a smaller number of shares, such Closing Price of the Texaco Common Stock will be proportionately reduced. Reclassifications of the Texaco Common Stock In the event that the Texaco Common Stock is changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification or otherwise (except to the extent otherwise provided under "-Texaco Common Stock Dividends and Extraordinary Dividends and Distributions" and "-Subdivisions and Combinations of Texaco Common Stock" above or pursuant to a Reorganization Event described under "-Dissolution of Texaco; Mergers, Consolidations or Sales of Assets; Spin-offs" below), the Conversion Amount will be calculated by using the aggregate Closing Prices of the shares of stock into which a share of Texaco Common Stock was changed on any Trading Day that follows the effectiveness of such change. A-2-8 As a result of the foregoing provisions, in the case of a reorganization or reclassification of the Texaco Common Stock, the Closing Prices of one or more securities in addition to or in substitution for the Texaco Common Stock may be used to calculate the Conversion Amount. For example, if the Texaco Common Stock were reclassified into one share of Texaco Class A Common Stock and one share of Texaco Class B Common Stock, the Conversion Amount would be calculated by reference to the Closing Prices of the Texaco Class A Common Stock and the Texaco Class B Common Stock. Other Dilution Events In the event that the Company (with the prior written approval of the Calculation Agent) or the Calculation Agent determines that an adjustment should be made to the Closing Price of the Texaco Common Stock on any of the Trading Days used to calculate the Conversion Amount as a result of one or more events or circumstances not otherwise described above (even if such event or circumstance is specifically excluded from the operation of the provisions described above), the Company shall at its own expense and acting reasonably request the Calculation Agent to determine as soon as practicable what adjustment (if any) is fair and reasonable to take account thereof. Dissolution of Texaco; Mergers, Consolidations or Sales of Assets; Spin-offs. In the event of any (i) consolidation or merger of Texaco with or into another entity (other than a consolidation or merger that does not result in a reclassification, conversion, exchange or cancellation of outstanding Texaco Common Stock), (ii) sale, transfer, lease or conveyance of all or substantially all of the assets of Texaco, (iii) liquidation, dissolution or winding up of Texaco or (iv) declaration of a distribution on the Texaco Common Stock of the common stock of any subsidiary of Texaco (a "Texaco Spin-off") (any of the events described in (i), (ii), (iii) or (iv), a "Reorganization Event"), for purposes of determining the Conversion Amount, the Closing Price of the Texaco Common Stock on any Trading Day subsequent to, in the case of a Reorganization Event other than a Texaco Spin-off, the effective time of such Reorganization Event or, in the case of a Texaco Spin-off, the record date fixed for the determination of the shareholders of Texaco entitled to receive the securities distributed in such Texaco Spin-off (the "Spin-off Record Date") will be deemed to be the amount equal to (1) the value of the cash and other property (including securities) received by a holder of a share of Texaco Common Stock (assuming such holder of Texaco Common Stock failed to exercise any rights of election and received per share the kind and amount received by a plurality of non-electing shares) in any such Reorganization Event (plus, in the case of a Texaco Spin-off, the value of a share A-2-9 of Texaco Common Stock), and (2) to the extent that such holder obtains securities in any Reorganization Event, the value of the cash and other property received by the holder of such securities in any subsequent event with respect to the issuer of such securities that would, if such issuer were Texaco, be a Reorganization Event. For purposes of determining any such Closing Prices, the value of (i) any cash and other property (other than securities) received in any such Reorganization Event will be an amount equal to the value of such cash and other property at the effective time of such Reorganization Event (as determined by the Calculation Agent, whose determination shall be conclusive and binding), and (ii) any property consisting of securities received in any such Reorganization Event will be an amount equal to the Closing Prices of such securities on any Trading Day following, in the case of a Reorganization Event other than a Texaco Spin-off, the effective time of such Reorganization Event or, in the case of a Texaco Spin-off, the Spin-off Record Date. If any action would require adjustment of the Closing Price pursuant to more than one of the foregoing provisions, only one adjustment shall be made and such adjustment shall be the amount of adjustment that has the highest absolute value to the Holder of this Note. No adjustment in the Closing Price shall be required unless such adjustment would require an increase or decrease of at least 1% of the Closing Price, but any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any subsequent adjustment. The Calculation Agent will promptly notify the Company and the Principal Conversion Agent, which will in turn notify the Holders, of any event requiring an adjustment and of the method of calculation to be used to make any dilution adjustment as described above. All determinations made by the Calculation Agent shall be at the sole discretion of the Calculation Agent and, in the absence of manifest error, shall be conclusive for all purposes and binding on the Company and the Holders, and the Calculation Agent shall have no liability therefor. All results of any calculation of the Conversion Amount will be rounded, if necessary, to the nearest one-one-hundred-thousandth of a percent (with five one-millionths of a percentage point being rounded downward).

The Notes are redeemable, at the option of the Company, in whole but not in part, at any time on or after August 5, 1999, at the principal amount thereof upon not less than 15 days' nor more than 30 days' notice to Holders. 8. Tax Redemption. The Notes may be redeemed as a whole, at the option of the Company at any time prior to maturity, upon the giving of a notice of redemption in the manner provided in the Indenture, at the principal amount thereof, together with accrued interest to the date fixed for redemption, if the Company determines that, as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of the United States or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment becomes effective on or after the date of this Note, the Company or Texaco Inc., as the case may be, has or will become obligated to pay Additional Amounts (as defined below) with respect to the Notes as described below under paragraph 9 hereof. Prior to the giving of any notice of redemption pursuant to this paragraph, the Company shall deliver to the Trustee (i) a certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company to so redeem have occurred (the date on which such certificate is delivered to the Trustee being the "Redemption Determination Date"), and (ii) an opinion of counsel reasonably acceptable to the Trustee to such effect based on such statement of facts; provided that no such notice of redemption shall be given earlier than 60 days prior to the earliest date on which the Company or Texaco Inc., as the case may be, would be obligated to pay such Additional Amounts if a payment in respect of any Note were then due. If the Company shall determine that any payment made outside the United States by the Company or Texaco Inc., as the case may be, by any Paying Agent of principal or interest due in respect of any Note or Coupon (as defined below) would, under any present or future laws or regulations of the United States, be subject to any certification, identification or other information reporting requirement of any kind, the effect of which is the disclosure to the Company, Texaco Inc., any Paying Agent or any governmental authority of the nationality, residence or identity of a beneficial owner of such Note or Coupon who is a United States Alien (as defined below under ", Payment of Additional Amounts") (other than such a requirement (a) that would not be applicable to a payment made by the Company or Texaco Inc., as the case may be, or any Paying A-2-11 Agent (i) directly to the beneficial owner or (ii) to a custodian, nominee or other agent of the beneficial owner, or (b) that can be satisfied by such custodian, nominee or other agent certifying to the effect that such beneficial owner is a United States Alien; provided that in each case referred to in clauses (a)(ii) and (b) payment by such custodian, nominee or agent to such beneficial owner would not otherwise be subject to any such requirement), the Company shall redeem the Notes, as a whole, at the principal amount thereof, together with accrued interest to the date fixed for redemption or, at the election of the Company or Texaco Inc., as the case may be, if the conditions of the next paragraph are satisfied, pay the additional amounts specified in such paragraph. The Company shall make such determination and election as soon as practicable and publish prompt notice thereof (the "Determination Notice") stating the effective date of such certification, identification or other information reporting requirements, whether the Company will redeem the Notes or has elected to pay the additional amounts specified in the next paragraph, and (if applicable) the last date by which the redemption of the Notes must take place, as provided in the next sentence. If the Company redeems the Notes, such redemption shall take place on such date, not later than one year after the publication of the Determination Notice, as the Company shall elect by notice to the Trustee. Notwithstanding the foregoing, the Company shall not so redeem the Notes if the Company or Texaco Inc., as the case may be, shall subsequently determine, not less than 30 days prior to the date fixed for redemption, that subsequent payments would not be subject to any such certification, identification or other information reporting requirement, in which case the Company shall publish prompt notice of such determination and any earlier redemption notice shall be revoked and of no further effect. If and so long as the certification, identification or other information reporting requirements referred to in the preceding paragraph would be fully satisfied by payment of a backup withholding tax or similar charge, the Company or Texaco Inc., as the case may be, may elect to pay as additional amounts such amounts as may be necessary so that every net payment made outside the United States following the effective date of such requirements by the Company or Texaco Inc., as the case may be, or any Paying Agent of principal or interest due in respect of any Note or any Coupon of which the beneficial owner is a United States Alien (but without any requirement that the nationality, residence or identity of such beneficial owner be disclosed to the Company, Texaco Inc., any Paying Agent or any governmental authority, with respect to the payment of such additional amounts), after deduction or withholding for or on account of such backup withholding tax or similar charge (other than a backup withholding tax or similar charge that (i) would not be applicable in the circumstances referred to in the second parenthetical clause of the first sentence of the preceding paragraph, or (ii) is imposed as a result of presentation of such Note or Coupon for payment A-2-12 more than 15 days after the date on which such payment becomes due and payable or on which payment thereof is duly provided for, whichever occurs later), will not be less than the amount provided for in such Note or Coupon to be then due and payable. In the event the Company or Texaco Inc., as the case may be, elects to pay any additional amounts pursuant to the applicable provisions of this paragraph, the Company shall have the right to redeem the Notes as a whole at any time pursuant to the provisions of the preceding paragraph and the redemption price of such Notes will not be reduced for applicable withholding taxes. If the Company or Texaco Inc., as the case may be, elects to pay additional amounts pursuant to this paragraph and the condition specified in the first sentence of this paragraph should no longer be satisfied, then the Company will redeem the Notes as a whole, pursuant to the applicable provisions of the preceding paragraph. 9. Payment of Additional Amounts. The Company will, subject to certain exceptions and limitations set forth below, pay such additional amounts (the "Additional Amounts") to the Holder of this Note who is a United States Alien as may be necessary in order that every net payment of the principal of and interest on this Note and any other amounts payable on such Note, after withholding for or on account of any present or future tax, assessment or governmental charge imposed upon or as a result of such payment by the United States (or any political subdivision or taxing authority thereof or therein), will not be less than the amount provided for in this Note to be then due and payable. The Company will not, however, be required to make any payment of Additional Amounts to any such Holder for or on account of: (a) any such tax, assessment or other governmental charge that would not have been so imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership or a corporation) and the United States and its possessions, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having or having had a permanent establishment therein or (ii) the presentation by the Holder of this Note for payment on a date more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; (b) any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment or governmental charge; A-2-13 (c) any tax, assessment or other governmental charge imposed by reason of such Holder's past or present status as a personal holding company or foreign personal holding company or controlled foreign corporation or passive foreign investment company with respect to the United States or as a corporation that accumulates earnings to avoid United States federal income tax or as a private foundation or other tax-exempt organization; (d) any tax, assessment or other governmental charge that is payable otherwise than by withholding from payments on or in respect of this Note; (e) any tax, assessment or other governmental charge required to be withheld by any Paying Agent from any payment of principal of or interest on this Note, if such payment can be made without such withholding by any other Paying Agent in a city in Western Europe; (f) any tax, assessment or other governmental charge that would not have been imposed but for the failure to comply with certification, information or other reporting requirements concerning the nationality, residence or identity of the owner or beneficial owner of this Note, if such compliance is required by statute or by regulation of the United States or of any political subdivision or taxing authority thereof or therein as a precondition to relief or exemption from such tax, assessment or other governmental charge; (g) any tax, assessment or other governmental charge imposed by reason of such Holder's past or present status as the actual or constructive owner of 10% or more of the total combined voting power of all classes of stock entitled to vote of the Company or as a direct or indirect subsidiary of the Company; or (h) any combination of items (a), (b), (c), (d), (e), (f) or (g); nor shall Additional Amounts be paid with respect to any payment on this Note to a United States Alien who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of the United States (or any political subdivision thereof) to be included in the income, for tax purposes, of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of this Note. A-2-14 As used herein, the term "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a nonresident alien individual, a nonresident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is a foreign corporation, a nonresident alien individual or a nonresident alien fiduciary of a foreign estate or trust. 10. Transfer. The Holder of this Note may transfer this Note in accordance with the Indenture; provided that this Note may be transferred only to a common depositary outside the United States for the Euroclear Operator and Cedel Bank or to a nominee of such a depositary. The Company may require the Holder of this Note, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. 11. Persons Deemed Owners. The bearer of this Note may be treated as the owner of it for all purposes. 12. Amendments and Waivers. Subject to certain exceptions, the Notes or the Indenture with respect to the Notes may be amended with the consent of the Holders of at least 50.1% in principal amount of the Notes outstanding, and any past default or compliance with any provision may be waived with the consent of the Holders of at least 50.1% in principal amount of the Notes outstanding. Without the consent of any Holder, the Indenture or the Notes may be amended to cure any ambiguity, defect or inconsistency; to provide for assumption of the Company's obligations to Holders; or to make any change that does not adversely affect the rights of any Holder. 13. Restrictive Covenants. The Notes are unsecured general obligation of the Company limited to $200,000,000 in aggregate principal amount. The Indenture does not limit other unsecured debt. It does limit certain mortgages and sale-leaseback transactions of Texaco Inc. if the property mortgaged or leased is a refinery or a manufacturing plant in the United States or any oil or gas producing property onshore or offshore the United States that is of material importance to the total business of Texaco Inc. and its consolidated subsidiaries. The limitations are subject to a number of A-2-15 important qualifications and exceptions. Once a year Texaco Inc. must report to the Trustee on compliance with the limitations. When a successor corporation assumes all the obligations of the Company under the Notes and the Indenture with respect to the Notes, the Company will be released from those obligations. 14. Defaults and Remedies. An Event of Default is: default for 30 days in payment of interest on the Notes; default in payment of principal on the Notes; failure by the Company or by Texaco Inc., as the case may be, for 90 days after notice to the Company to comply with any of its other agreements in the Notes or the Indenture; and certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes may declare all the Notes to be due and payable immediately. Holders may not enforce the Notes or the Indenture with respect to the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Notes or the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. 15. Trustee Dealings with Company or Texaco Inc. The Chase Manhattan Bank as Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company, Texaco Inc. or any affiliates of either, and may otherwise deal with the Company, Texaco Inc. or any affiliates of either, as if it were not Trustee. 16. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company or Texaco Inc. shall not have any liability for any obligations of the Company or Texaco Inc. under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes. A-2-16 17. Exchange for Definitive Notes. The beneficial owner of all or a portion of this Note may exchange its interest in this Note upon not less than 30 days' written notice to any Non-U.S. Paying Agent through the relevant clearing system, in whole, for Notes in definitive bearer form with interest coupons ("Coupons") attached ("Definitive Notes") in denominations of U.S.$10,000. Interests in this Note shall also be exchanged by the Company in whole, but not in part, for Definitive Notes if (i) this Note is accelerated following an Event of Default or (ii) either the Euroclear Operator or Cedel Bank is closed for business for a continuous period of fourteen days (other than by reason of public holidays) or announces an intention to cease business permanently or in fact does so. The Company shall give notice to the Principal Paying Agent promptly following any such acceleration or upon learning of any such closure. Any exchanges referred to above shall be made at the office of the Principal Paying Agent, upon compliance with the procedures set forth in the Indenture; provided that the Company shall not be required to exchange this Note for a period of fifteen calendar days preceding the first publication of a notice of redemption of the Notes. Upon exchange of this Note in whole for Definitive Notes, the Principal Paying Agent shall cause Schedule A of this Note to be endorsed to reflect the reduction of the principal amount hereof by an amount equal to the aggregate principal amount of such Definitive Notes, whereupon the principal amount hereof shall be reduced for all purposes by the amount so exchanged and noted. All such exchanges of this Note will be free of service charge, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The date of any Definitive Note delivered upon any exchange of this Note shall be such that no gain or loss of interest results from such exchange. All (and not less than all) interests in this Note will be exchanged for Definitive Notes as soon as practicable after (i) the first beneficial owner of an interest in this Note exchanges its interest for Definitive Notes or (ii) the Company gives notice to the Principal Paying Agent of an acceleration of the Note or the closure of a relevant clearing system as described above. 18. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. A-2-17 GUARANTY TEXACO INC., a Delaware corporation (the "Guarantor"), unconditionally guarantees to the Holder of this Note the due and punctual payment of the principal of and interest on this Note.

Interest Payable: August 5 Texaco Capital Inc. promises to pay to bearer, upon surrender hereof, the principal sum of U.S.$10,000 on August 5, 2004 (except to the extent previously redeemed or converted).

Interest. Texaco Capital Inc. (the "Company"), a Delaware corporation, promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Company will pay interest annually on August 5 of each year (each, an "Interest Payment Date"). Interest on the Note will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from August 5, 1997 (the "Issue Date"). Except as provided in the Indenture, this Note will cease to bear interest from and after the earliest of (a) August 5, 2004, (b) the Interest Payment Date immediately preceding the Conversion Date (as defined below) relating to the conversion of this Note into the Conversion Amount (as defined below) or, if there is no such Interest Payment Date, the Issue Date or (c) the date fixed for redemption of this Note. If interest is required to be calculated for a period of less than one year, it will be calculated on the basis of a 360-day year consisting of 12 months of 30 days each. 2. Method of Payment. Payment of principal and interest on this Note will be made in immediately available funds, subject to any applicable laws and regulations, only against presentation and surrender of this Note or the relevant interest coupon (a "Coupon"), as the case may be, at the office of any Non-U.S. Paying Agent by check or, at the option of the Holder of this Note, by wire transfer of immediately available funds to an account maintained by the payee with a bank located outside the United States if appropriate wire transfer instructions have been received by such Non-U.S. Paying Agent not less than 15 calendar days prior to an applicable payment date. No payment on this Note or any Coupon appertaining hereto will be made at any office or agency of the Company in the United States (as defined below) or by check mailed to an address in the United States or by wire transfer to an account maintained by the Holder of this Note or such Coupon with a bank in the United States except as may be permitted under United States federal tax laws and regulations then in effect without adverse tax consequences to the Company. Notwithstanding the foregoing, in the event that payment in U.S. dollars of the full amount payable on this Note or any Coupon appertaining hereto at the offices of all Non-U.S. Paying Agents (as defined below) would be illegal or effectively precluded as a result of exchange controls or similar restrictions, payment on this Note or such Coupon will be made by a Paying Agent in the Borough of A-3-3 Manhattan, The City of New York, if and only if (i) such Paying Agent, under applicable law and regulations, would be able to make such payment and (ii) such payment would not involve, in the opinion of the Company, adverse tax consequences for the Company. 3.

Initially, The Chase Manhattan Bank, as Trustee (the "Trustee"), at its office in London at Trinity Tower, 9 Thomas More Street, London E19YT, England, will act as the principal Paying Agent for the Notes outside the United States (the "Principal Paying Agent") and as the principal Conversion Agent for the Notes outside the United States (the "Principal Conversion Agent"). Initially, Chase Manhattan Bank Luxembourg S.A., at its office in Luxembourg at 5 rue Plaetis, L-2338 Luxembourg, Luxembourg, will act as a Paying Agent and a Conversion Agent in Luxembourg. The Company may appoint additional Paying Agents or Conversion Agents or change any Paying Agent or Conversion Agent without notice to Holders (any such additional Paying Agent or other Paying Agent for the Notes outside the United States, a "Non-U.S. Paying Agent"). 4. Indenture. The Company issued this Note as part of a Series of Securities, designated as "3.50% Guaranteed Cash-Settled Convertible Notes Due 2004" (the "Notes"), under an indenture dated as of August 24, 1984, as supplemented and restated by the First Supplemental Indenture dated as of January 31, 1990, as further amended by the First Supplement to the First Supplemental Indenture dated as of October 11, 1990, and as further amended by the Second Supplement to the First Supplemental Indenture dated as of August 5, 1997 (as so supplemented and amended, the "Indenture"), among the Company, Texaco Inc. and the Trustee. The terms of this Note include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code ss.ss. 7aaa-77bbbb) as amended (the "Act"). This Note is subject to all such terms, and the Holder of this Note is referred to the Indenture and the Act for a statement of them. All terms used in this Note which are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture. A-3-4 5. Guaranty.

On any Business Day (as defined below) during the Conversion Period, the Holder of this Note may give notice to any Conversion Agent, who will provide copies to the Company, the Calculation Agent, the Principal Conversion Agent and the Trustee, in writing in the form provided in the Indenture (a "Conversion Notice"), that such Holder elects to convert this Note into the Conversion Amount. To be converted, this Note, together with all unmatured Coupons appertaining hereto (for this purpose treating any Coupon expressed to be payable on the relevant Conversion Date as an unmatured Coupon), must be surrendered to a Conversion Agent together with the Conversion Notice relating thereto. Any question as to the validity of a Conversion Notice or as to whether such notice has been properly and timely given will be resolved finally by the Principal Conversion Agent in its sole discretion. On and after the Conversion Date with respect to this Note, unmatured Coupons relating hereto (whether or not attached hereto) shall become void and no payment shall be made in respect thereof. On the Settlement Date (as defined below) with respect to the conversion of this Note, the Holder of this Note will be entitled to receive the Conversion Amount in cash. Any payment of the Conversion Amount shall be deemed to be a payment of principal for all purposes under the Indenture and the Notes. As used herein: (a) the term "Business Day" means any day that is not a Saturday, a Sunday or a day on which banking institutions or trust companies in the City of New York, the City of London or Luxembourg are authorized or obligated by law or executive order to close; (b) the term "Closing Price" means, with respect to any security on any date, the closing sale price or last reported sale price for the security on the principal securities exchange or national market system on which such security is listed for trading or quoted on such date or, if such security is not so listed or quoted on such date, the fair market value of A-3-5 such security on such date, as determined by the Calculation Agent, in each case subject to adjustment as described below; (c) the term "Conversion Amount" means, (i) if the relevant Conversion Notice is delivered prior to notice of redemption having been given by the Company, an amount in cash determined by the Calculation Agent to be the Closing Price of the Texaco Common Stock on the related Conversion Date (or, if the Conversion Date is not a Trading Day, on the first following day that is a Trading Day) multiplied by the Conversion Ratio, or (ii) if the relevant Conversion Notice is delivered after the giving of a notice of redemption by the Company or within eight Business Days prior to July 22, 2004, an amount in cash determined by the Calculation Agent to be the average of the Closing Prices of the Texaco Common Stock on the five consecutive Trading Days commencing on the applicable Conversion Date multiplied by the Conversion Ratio; (d) the term "Conversion Date" means, with respect to any Note surrendered for conversion, the second Business Day immediately following the date of delivery of the related Conversion Notice to the relevant Conversion Agent; (e) the term "Conversion Period" means the period commencing on September 15, 1997 and ending at 5:00 P.M., London time, on July 22, 2004 or, if this Note shall have been called for redemption prior to August 5, 2004, ending at 5:00 P.M., London time, on the date eight Business Days prior to the date fixed for redemption thereof; provided that if the Company defaults in making payment in full in respect of this Note or prior to the date fixed for redemption hereof, the Conversion Period will continue until 5:00 P.M., London time, on the date upon which the full amount of the moneys payable in respect of this Note has been duly received by the Trustee and notice of such receipt has been duly given to the Holders of the Notes by the Trustee; (f) the term "Conversion Ratio" means 71.35 shares of Texaco Common Stock per U.S. $10,000 principal amount of Notes; (g) the term "Settlement Date" means the day as soon as reasonably practicable after the Conversion Date determined by the Calculation Agent and the Principal Conversion Agent to be the day for payment of the Conversion Amount; A-3-6 (h) the term "Texaco Common Stock" means the common stock of Texaco Inc.; and (i) "Trading Day" means, with respect to any security, any day that is a trading day on the principal securities exchange or national market system on which such security is then listed other than a day on which (i) trading on such exchange or national market system is scheduled to close prior to its regular weekday closing time or (ii) there occurs any suspension of or limitation imposed on trading of such security on such exchange during the one-half hour period that ends at its regular weekday closing time that is, in the determination of the Calculation Agent, material. The Closing Price of the Texaco Common Stock on any of the Trading Days used to calculate the Conversion Amount will be subject to adjustment by the Calculation Agent as described below to the extent that any of the events requiring such adjustment occurs during the period commencing on the date of this Note and ending on such Trading Day. Texaco Common Stock Dividends and Extraordinary Dividends and Distributions In the event that a dividend or other distribution is declared (i) on any class of Texaco capital stock, payable in shares of Texaco Common Stock, (ii) on the Texaco Common Stock payable in cash in an amount greater than 10% of the Closing Price of the Texaco Common Stock on the date fixed for the determination of the shareholders of Texaco entitled to receive such cash dividend (an "Extraordinary Cash Dividend"), or (iii) on the Texaco Common Stock of evidences of indebtedness or assets (including securities, but excluding any dividend or distribution covered by clause (i) or any Texaco Spin-off described under "-Dissolution of Texaco; Mergers, Consolidations or Sales of Assets; Spin-offs" below) (an "Extraordinary Distribution"), any Closing Price of the Texaco Common Stock used to calculate the Conversion Amount on any Trading Day that follows the date (the "Texaco Record Date") fixed for the determination of the shareholders of Texaco entitled to receive such dividend or other distribution shall be increased by multiplying such Closing Price by a fraction, the numerator of which shall be the number of shares of Texaco Common Stock outstanding on the Texaco Record Date plus the number of shares constituting such distribution or, in the case of any Extraordinary Cash Dividend or Extraordinary Distribution, plus the number of shares of Texaco Common Stock that could be purchased with the amount of such Extraordinary Cash Dividend or A-3-7 the fair market value (as determined by the Calculation Agent, whose determination shall be conclusive and binding) of the evidences of indebtedness or assets constituting such Extraordinary Distribution at the Closing Price on the Trading Day immediately subsequent to such Texaco Record Date, and the denominator of which shall be the number of shares of Texaco Common Stock outstanding on the Texaco Record Date. Subdivisions and Combinations of the Texaco Common Stock In the event that the outstanding shares of Texaco Common Stock are subdivided into a greater number of shares, the Closing Price of the Texaco Common Stock used to calculate the Conversion Amount on any Trading Day that follows the date on which such subdivision becomes effective will be proportionately increased and, conversely, in the event that the outstanding shares of Texaco Common Stock are combined into a smaller number of shares, such Closing Price of the Texaco Common Stock will be proportionately reduced. Reclassifications of the Texaco Common Stock In the event that the Texaco Common Stock is changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification or otherwise (except to the extent otherwise provided under "-Texaco Common Stock Dividends and Extraordinary Dividends and Distributions" and "-Subdivisions and Combinations of Texaco Common Stock" above or pursuant to a Reorganization Event described under "-Dissolution of Texaco; Mergers, Consolidations or Sales of Assets; Spin-offs" below), the Conversion Amount will be calculated by using the aggregate Closing Prices of the shares of stock into which a share of Texaco Common Stock was changed on any Trading Day that follows the effectiveness of such change. As a result of the foregoing provisions, in the case of a reorganization or reclassification of the Texaco Common Stock, the Closing Prices of one or more securities in addition to or in substitution for the Texaco Common Stock may be used to calculate the Conversion Amount. For example, if the Texaco Common Stock were reclassified into one share of Texaco Class A Common Stock and one share of Texaco Class B Common Stock, the Conversion Amount would be calculated by reference to the Closing Prices of the Texaco Class A Common Stock and the Texaco Class B Common Stock. A-3-8 Other Dilution Events In the event that the Company (with the prior written approval of the Calculation Agent) or the Calculation Agent determines that an adjustment should be made to the Closing Price of the Texaco Common Stock on any of the Trading Days used to calculate the Conversion Amount as a result of one or more events or circumstances not otherwise described above (even if such event or circumstance is specifically excluded from the operation of the provisions described above), the Company shall at its own expense and acting reasonably request the Calculation Agent to determine as soon as practicable what adjustment (if any) is fair and reasonable to take account thereof. Dissolution of Texaco; Mergers, Consolidations or Sales of Assets; Spin-offs In the event of any (i) consolidation or merger of Texaco with or into another entity (other than a consolidation or merger that does not result in a reclassification, conversion, exchange or cancellation of outstanding Texaco Common Stock), (ii) sale, transfer, lease or conveyance of all or substantially all of the assets of Texaco, (iii) liquidation, dissolution or winding up of Texaco or (iv) declaration of a distribution on the Texaco Common Stock of the common stock of any subsidiary of Texaco (a "Texaco Spin-off") (any of the events described in (i), (ii), (iii) or (iv), a "Reorganization Event"), for purposes of determining the Conversion Amount, the Closing Price of the Texaco Common Stock on any Trading Day subsequent to, in the case of a Reorganization Event other than a Texaco Spin-off, the effective time of such Reorganization Event or, in the case of a Texaco Spin-off, the record date fixed for the determination of the shareholders of Texaco entitled to receive the securities distributed in such Texaco Spin-off (the "Spin-off Record Date") will be deemed to be the amount equal to (1) the value of the cash and other property (including securities) received by a holder of a share of Texaco Common Stock (assuming such holder of Texaco Common Stock failed to exercise any rights of election and received per share the kind and amount received by a plurality of non-electing shares) in any such Reorganization Event (plus, in the case of a Texaco Spin-off, the value of a share of Texaco Common Stock), and (2) to the extent that such holder obtains securities in any Reorganization Event, the value of the cash and other property received by the holder of such securities in any subsequent event with respect to the issuer of such securities that would, if such issuer were Texaco, be a Reorganization Event. For purposes of determining any such Closing Prices, the value of (i) any cash and other property (other than securities) received in any such Reorganization Event will be an amount equal to the value of such cash and other property at the effective time of such Reorganization Event (as determined A-3-9 by the Calculation Agent, whose determination shall be conclusive and binding), and (ii) any property consisting of securities received in any such Reorganization Event will be an amount equal to the Closing Prices of such securities on any Trading Day following, in the case of a Reorganization Event other than a Texaco Spin-off, the effective time of such Reorganization Event or, in the case of a Texaco Spin-off, the Spin-off Record Date. If any action would require adjustment of the Closing Price pursuant to more than one of the foregoing provisions, only one adjustment shall be made and such adjustment shall be the amount of adjustment that has the highest absolute value to the Holder of this Note. No adjustment in the Closing Price shall be required unless such adjustment would require an increase or decrease of at least 1% of the Closing Price, but any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any subsequent adjustment. The Calculation Agent will promptly notify the Company and the Principal Conversion Agent, which will in turn notify the Holders, of any event requiring an adjustment and of the method of calculation to be used to make any dilution adjustment as described above. All determinations made by the Calculation Agent shall be at the sole discretion of the Calculation Agent and, in the absence of manifest error, shall be conclusive for all purposes and binding on the Company and the Holders, and the Calculation Agent shall have no liability therefor. All results of any calculation of the Conversion Amount will be rounded, if necessary, to the nearest one-one-hundred-thousandth of a percent (with five one-millionths of a percentage point being rounded downward). 7. Redemption. The Notes are redeemable, at the option of the Company, in whole but not in part, at any time on or after August 5, 1999, at the principal amount thereof upon not less than 15 days' nor more than 30 days' notice to Holders. 8. Tax Redemption. The Notes may be redeemed as a whole, at the option of the Company at any time prior to maturity, upon the giving of a notice of redemption in the manner provided in the Indenture, at the principal amount thereof, together with accrued interest to the date fixed for redemption, if the Company determines that, A-3-10 as a result of any change in or amendment to the laws (or any regulations or rulings promulgated thereunder) of the United States or of any political subdivision or taxing authority thereof or therein affecting taxation, or any change in official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment becomes effective on or after the date of this Note, the Company or Texaco Inc., as the case may be, has or will become obligated to pay Additional Amounts (as defined below) with respect to the Notes as described below under paragraph 9 hereof. Prior to the giving of any notice of redemption pursuant to this paragraph, the Company shall deliver to the Trustee (i) a certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company to so redeem have occurred (the date on which such certificate is delivered to the Trustee being the "Redemption Determination Date"), and (ii) an opinion of counsel reasonably acceptable to the Trustee to such effect based on such statement of facts; provided that no such notice of redemption shall be given earlier than 60 days prior to the earliest date on which the Company or Texaco Inc., as the case may be, would be obligated to pay such Additional Amounts if a payment in respect of any Note were then due. If the Company shall determine that any payment made outside the United States by the Company or Texaco Inc., as the case may be, by any Paying Agent of principal or interest due in respect of any Note or Coupon would, under any present or future laws or regulations of the United States, be subject to any certification, identification or other information reporting requirement of any kind, the effect of which is the disclosure to the Company, Texaco Inc., any Paying Agent or any governmental authority of the nationality, residence or identity of a beneficial owner of such Note or Coupon who is a United States Alien (as defined below under ", Payment of Additional Amounts") (other than such a requirement (a) that would not be applicable to a payment made by the Company or Texaco Inc., as the case may be, or any Paying Agent (i) directly to the beneficial owner or (ii) to a custodian, nominee or other agent of the beneficial owner, or (b) that can be satisfied by such custodian, nominee or other agent certifying to the effect that such beneficial owner is a United States Alien; provided that in each case referred to in clauses (a)(ii) and (b) payment by such custodian, nominee or agent to such beneficial owner would not otherwise be subject to any such requirement), the Company shall redeem the Notes, as a whole, at the principal amount thereof, together with accrued interest to the date fixed for redemption or, at the election of the Company or Texaco Inc., as the case may be, if the conditions of the next paragraph are satisfied, pay the additional amounts specified in such paragraph. The Company shall make such determination and election as soon as practicable and publish prompt notice A-3-11 thereof (the "Determination Notice") stating the effective date of such certification, identification or other information reporting requirements, whether the Company will redeem the Notes or has elected to pay the additional amounts specified in the next paragraph, and (if applicable) the last date by which the redemption of the Notes must take place, as provided in the next sentence. If the Company redeems the Notes, such redemption shall take place on such date, not later than one year after the publication of the Determination Notice, as the Company shall elect by notice to the Trustee. Notwithstanding the foregoing, the Company shall not so redeem the Notes if the Company or Texaco Inc., as the case may be, shall subsequently determine, not less than 30 days prior to the date fixed for redemption, that subsequent payments would not be subject to any such certification, identification or other information reporting requirement, in which case the Company shall publish prompt notice of such determination and any earlier redemption notice shall be revoked and of no further effect. If and so long as the certification, identification or other information reporting requirements referred to in the preceding paragraph would be fully satisfied by payment of a backup withholding tax or similar charge, the Company or Texaco Inc., as the case may be, may elect to pay as additional amounts such amounts as may be necessary so that every net payment made outside the United States following the effective date of such requirements by the Company or Texaco Inc., as the case may be, or any Paying Agent of principal or interest due in respect of any Note or any Coupon of which the beneficial owner is a United States Alien (but without any requirement that the nationality, residence or identity of such beneficial owner be disclosed to the Company, Texaco Inc., any Paying Agent or any governmental authority, with respect to the payment of such additional amounts), after deduction or withholding for or on account of such backup withholding tax or similar charge (other than a backup withholding tax or similar charge that (i) would not be applicable in the circumstances referred to in the second parenthetical clause of the first sentence of the preceding paragraph, or (ii) is imposed as a result of presentation of such Note or Coupon for payment more than 15 days after the date on which such payment becomes due and payable or on which payment thereof is duly provided for, whichever occurs later), will not be less than the amount provided for in such Note or Coupon to be then due and payable. In the event the Company or Texaco Inc., as the case may be, elects to pay any additional amounts pursuant to the applicable provisions of this paragraph, the Company shall have the right to redeem the Notes as a whole at any time pursuant to the provisions of the preceding paragraph and the redemption price of such Notes will not be reduced for applicable withholding taxes. If the Company or Texaco Inc., as the case may be, elects to pay additional amounts pursuant to this paragraph and the condition specified in the first sentence of this A-3-12 paragraph should no longer be satisfied, then the Company will redeem the Notes as a whole, pursuant to the applicable provisions of the preceding paragraph. 9. Payment of Additional Amounts. The Company will, subject to certain exceptions and limitations set forth below, pay such additional amounts (the "Additional Amounts") to the Holder of this Note or of any Coupon appertaining hereto who is a United States Alien as may be necessary in order that every net payment of the principal of and interest on this Note and any other amounts payable on such Note, after withholding for or on account of any present or future tax, assessment or governmental charge imposed upon or as a result of such payment by the United States (or any political subdivision or taxing authority thereof or therein), will not be less than the amount provided for in this Note or such Coupon to be then due and payable. The Company will not, however, be required to make any payment of Additional Amounts to any such Holder for or on account of: (a) any such tax, assessment or other governmental charge that would not have been so imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership or a corporation) and the United States and its possessions, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or having or having had a permanent establishment therein or (ii) the presentation by the Holder of this Note or any such Coupon for payment on a date more than 15 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; (b) any estate, inheritance, gift, sales, transfer or personal property tax or any similar tax, assessment or governmental charge; (c) any tax, assessment or other governmental charge imposed by reason of such Holder's past or present status as a personal holding company or foreign personal holding company or controlled foreign corporation or passive foreign investment company with respect to the United States or as a corporation that accumulates earnings to avoid United States federal income tax or as a private foundation or other tax-exempt organization; A-3-13 (d) any tax, assessment or other governmental charge that is payable otherwise than by withholding from payments on or in respect of this Note; (e) any tax, assessment or other governmental charge required to be withheld by any Paying Agent from any payment of principal of or interest on this Note, if such payment can be made without such withholding by any other Paying Agent in a city in Western Europe; (f) any tax, assessment or other governmental charge that would not have been imposed but for the failure to comply with certification, information or other reporting requirements concerning the nationality, residence or identity of the owner or beneficial owner of this Note, if such compliance is required by statute or by regulation of the United States or of any political subdivision or taxing authority thereof or therein as a precondition to relief or exemption from such tax, assessment or other governmental charge; (g) any tax, assessment or other governmental charge imposed by reason of such Holder's past or present status as the actual or constructive owner of 10% or more of the total combined voting power of all classes of stock entitled to vote of the Company or as a direct or indirect subsidiary of the Company; or (h) any combination of items (a), (b), (c), (d), (e), (f) or (g); nor shall Additional Amounts be paid with respect to any payment on this Note to a United States Alien who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of the United States (or any political subdivision thereof) to be included in the income, for tax purposes, of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of this Note. As used herein, the term "United States Alien" means any person who, for United States federal income tax purposes, is a foreign corporation, a nonresident alien individual, a nonresident alien fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is a foreign corporation, a nonresident alien individual or a nonresident alien fiduciary of a foreign estate or trust. A-3-14 10. Transfer. The Holder of this Note may transfer this Note in accordance with the Indenture. The Company may require the Holder of this Note, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. 11. Persons Deemed Owners. The bearer of this Note may be treated as the owner of it for all purposes. 12. Amendments and Waivers. Subject to certain exceptions, the Notes or the Indenture with respect to the Notes may be amended with the consent of the Holders of at least 50.1% in principal amount of the Notes outstanding, and any past default or compliance with any provision may be waived with the consent of the Holders of at least 50.1% in principal amount of the Notes outstanding. Without the consent of any Holder, the Indenture or the Notes may be amended to cure any ambiguity, defect or inconsistency; to provide for assumption of the Company's obligations to Holders; or to make any change that does not adversely affect the rights of any Holder. 13. Restrictive Covenants. The Notes are unsecured general obligation of the Company limited to $200,000,000 in aggregate principal amount. The Indenture does not limit other unsecured debt. It does limit certain mortgages and sale-leaseback transactions of Texaco Inc. if the property mortgaged or leased is a refinery or a manufacturing plant in the United States or any oil or gas producing property onshore or offshore the United States that is of material importance to the total business of Texaco Inc. and its consolidated subsidiaries. The limitations are subject to a number of important qualifications and exceptions. Once a year Texaco Inc. must report to the Trustee on compliance with the limitations. When a successor corporation assumes all the obligations of the Company under the Notes and the Indenture with respect to the Notes, the Company will be released from those obligations. A-3-15 14. Defaults and Remedies. An Event of Default is: default for 30 days in payment of interest on the Notes; default in payment of principal on the Notes; failure by the Company or by Texaco Inc., as the case may be, for 90 days after notice to the Company to comply with any of its other agreements in the Notes or the Indenture; and certain events of bankruptcy or insolvency. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes may declare all the Notes to be due and payable immediately. Holders may not enforce the Notes or the Indenture except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Notes or the Indenture with respect to the Notes. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in their interests. 15. Trustee Dealings with Company or Texaco Inc. The Chase Manhattan Bank as Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company, Texaco Inc. or any affiliates of either, and may otherwise deal with the Company, Texaco Inc. or any affiliates of either, as if it were not Trustee. 16. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Company or Texaco Inc. shall not have any liability for any obligations of the Company or Texaco Inc. under the Notes or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes. 17. Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. A-3-16 GUARANTY TEXACO INC., a Delaware corporation (the "Guarantor"), unconditionally guarantees to the Holder of this Note the due and punctual payment of the principal of and interest on this Note. The Guarantor shall not be entitled to receive any payments based upon a right of subrogation with respect to any amounts paid by the Guarantor to Holders until the principal of and interest on all Notes shall have been paid in full or for which payment has been provided.
