if such change is announced at least five (5) days prior to the scheduled beginning of the first Offering Period to be affected. 
  
 4. Eligibility. 
  
 (a) First Offering Period. With respect to the first Offering Date of the First Offering Period, each individual who is an Employee as of
the date immediately preceding the IPO Date shall be eligible to be automatically granted an option to participate in such First Offering Period and these individuals shall thereby be automatically enrolled in the First Offering Period (subject to
the requirements of Sections 5(a) and 6(a)(i) below). 
  
 (b)
Subsequent Offering Periods. With respect to Offering Dates occurring after the IPO Date, any individual who is an Employee as of an applicable Offering Date shall be eligible to participate in such Offering Period, subject to the
requirements of Section 5 and to the limitations imposed by the Plan and Code Section 423(b). 
  
 5. Participation; Subscription Agreement. 
  
 (a) First Offering Period. With respect to the First Offering Period, an Employee eligible under Section 4(a) above, shall be granted an
option under Section 6(a)(i) below, and shall be entitled to continue his or her participation in such Offering Period only if he or she submits to the Company’s payroll office (or its designee) a properly completed subscription agreement
authorizing payroll deductions in accordance with Section 5(c) below in the form of subscription agreement provided by the Board for such purpose (i) no earlier than the effective date of the filing of the Company’s Registration Statement on
Form S-8 with respect to the Shares issuable under the Plan and (ii) no later than thirty (30) days following the date on which the Form S-8 becomes effective (such period referred to as the “Enrollment Period”). A
participant’s failure to submit the subscription agreement during the Enrollment Period pursuant to this Section 5(a) shall result in the automatic termination of his or her participation in the First Offering Period in accordance with Section
10(a). Payroll deductions shall commence with respect to the First Offering Period as of the first payday following the expiration of the Enrollment Period or on such other payday as is specified by the Board. The Board will provide notice to
participants granted an option under Section 6(a)(i) above as to the expiration of the Enrollment Period. 
  
 (b) Subsequent Offering Periods. An Employee who is eligible to participate in the Plan under Section 4(b) above may become a participant by
(i) submitting to the Company’s payroll office (or its designee), on or before a date prescribed by the Board prior to 
  

 4 

 
an applicable Offering Date, a properly completed subscription agreement authorizing payroll deductions in the form provided by the Board for such purpose,
or (ii) following an electronic or other enrollment procedure prescribed by the Board. 
  
 (c) Requirements as to Subscription Agreement and Participation. 
  
 (i) A participant’s subscription agreement shall set forth the percentage of the participant’s Compensation to be paid as Contributions
pursuant to the Plan, which percentage shall be a whole percentage and shall be not less than one percent (1%) and not more than fifteen percent (15%) (or such other maximum percentage as the Board may establish from time to time before an Offering
Period) of such participant’s Compensation on each payday during the Offering Period. 
  
 (ii) A participant’s subscription shall be effective for the Offering Period with respect to which it is filed, and also shall be automatically effective for each successive Offering Period that commences after
the end of the Offering Period for which it is filed, unless the participant changes his or her Contribution rate for the next Offering Period by following the procedures set forth in Section 5(c)(iii) below, withdraws from the Plan in accordance
with Section 10, or is otherwise ineligible to participate in the next Offering Period. 
  
 (iii) While a participant may not change his or her rate of Contributions during an ongoing Offering Period, a participant may discontinue his or her participation in the Plan as provided in Section 10 at any time
prior to a Purchase Date. In addition, subject to Section 5(b) above, a participant may change his or her rate of Contributions under the Plan with respect to the next Offering Period by filing a new subscription agreement with the Company on or
prior to the tenth (10th) business day prior to the first day of such next Offering Period (or by such other date as
is specified by the Board) or by following an electronic or other procedure designated by the Board, in each case specifying the new Contribution rate that shall apply with respect to such Offering Period. Such change in Contribution rate will be
effective as of the first payroll period following commencement of the next Offering Period. Notwithstanding the above, with respect to the First Offering Period, submission by a participant of a subscription agreement authorizing payroll deductions
at a rate that is less than the maximum rate at which they would be entitled to participate under the Plan shall be permitted. Payroll deductions for the First Offering Period shall commence on the first payday on or following the end of the
Enrollment Period (or on such other date as the Board may specify). 
  
 6. Grant of Option; Limitations. 
  
 (a) Grant of Option. 
  
 (i)
First Offering Period. With respect to the First Offering Period, each eligible Employee shall automatically be granted an option to purchase on the Purchase Date for the First Offering Period a number of Shares of the Company’s
Common Stock determined by dividing the maximum amount permitted under the Plan (which amount shall be a percentage of such Employee’s Compensation) with respect to such Offering Period, by the applicable Purchase Price, subject to the
limitations in subsections (c), (d) and (e) of this 
  

 5 

 Section 6 (which limitations shall be applied in a manner that permits granting of an option of less than the maximum
amount specified in this Section 6(a)(i) in order to conform to the limitations of such subsections). 
  
 (ii) Subsequent Offering Periods. Except with respect to the First Offering Period, and subject to the limitations in subsections (c), (d)
and (e) of this Section 6 and Section 11(b), on the Offering Date of each Offering Period, each eligible Employee participating in such Offering Period shall be granted an option to purchase on each Purchase Date within such Offering Period a number
of Shares of the Company’s Common Stock determined by dividing such Employee’s Contributions accumulated prior to such Purchase Date and retained in the participant’s account as of the Purchase Date by the applicable Purchase Price.

  
 (b) Acceptance of Option Grant. An Employee may
accept the grant of such option (i) with respect to the First Offering Period, by submitting a properly completed subscription agreement in accordance with the requirements of Section 5(a) above on or before the last day of the Enrollment Period,
and (ii) with respect to subsequent Offering Periods, by electing to participate in the Plan in accordance with the requirements of Section 5(b). Exercise of the option shall occur as provided in Section 8 below. 
  
 (c) Limit on Number of Shares Purchased. Notwithstanding the
above, the maximum number of Shares an Employee may purchase during each Offering Period (including the First Offering Period) shall be 2,500 Shares (before giving effect to a stock split effected in connection with the Company’s initial public
offering and subject to any further adjustment pursuant to Section 17 below), and provided further that such purchase shall be subject to the limitations set forth in Sections 11(b). In addition to the limits on an Employee’s participation in
the Plan set forth herein, the Board in its sole discretion may establish new or change existing limits on the number of Shares an Employee may elect to purchase with respect to any Offering Period if such limit is announced at least ten (10) days
prior to the scheduled beginning of the first Offering Period to be affected. 
  
 (d) Limit on Value of Shares Purchased. Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an option under the Plan if such option would permit his or her rights to
purchase stock under all employee stock purchase plans (described in Section 423 of the Code) of the Company and its Subsidiaries to accrue at a rate which exceeds twenty-five thousand dollars ($25,000) of the Fair Market Value (as defined in
Section 2(l) above) of such stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time. 
  
 (e) 5% Owner Limit. Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an option under the Plan if,
immediately after the grant, such Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company and/or hold outstanding options to purchase stock
possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any subsidiary of the Company. 
  

 6 

 7. Method of Payment for Purchase of Shares. This Plan shall be operated as a payroll
deduction plan. All payroll deductions made by a participant shall be credited to his or her account under the Plan. A participant may not make any additional payments into such account other than through the payroll deduction feature of the Plan.

  
 (a) Limitation on Payroll Deductions.
Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and the limitations of Section 6, a participant’s payroll deductions may be decreased by the Company to zero percent (0%) at any time during
an Offering Period. Payroll deductions shall re-commence at the rate provided in such participant’s subscription agreement at the beginning of the next Offering Period or, in the case of the limitation of Section 6(d), the first Offering Period
which is scheduled to end in the following calendar year, unless the participant withdraws in accordance with Section 10, or is otherwise ineligible to participate in such Offering Period. 
  
 (b) Tax Withholding. At the time an option is exercised, in
whole or in part, or at the time some or all of the Company’s Common Stock issued under the Plan is disposed of, the participant must make adequate provision for the Company’s federal, state, or other tax withholding obligations, if any,
which arise upon the exercise of the option or the disposition of the Common Stock. At any time, the Company may, but shall not be obligated to, withhold from the participant’s compensation the amount necessary for the Company to meet
applicable withholding obligations, including any withholding required to make available to the Company any tax deductions or benefits attributable to sale or early disposition of Common Stock by the participant. 
  
 (c) Interest. No interest shall accrue on the Contributions of
a participant in the Plan. 
  
 8. Exercise of
Option. 
  
 (a) During his or her lifetime, a
participant’s option to purchase Shares hereunder is exercisable only by him or her. 
  
 (b) Unless a participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of Shares will be exercised automatically on the Purchase Date of an Offering Period, and unless otherwise
limited by Section 6 or Section 11(b), the maximum number of full Shares subject to the option will be purchased at the applicable Purchase Price with the accumulated Contributions in the participant’s account. 
  
 (c) No fractional Shares shall be purchased. Any payroll deductions
accumulated in a participant’s account which are not sufficient to purchase a full Share shall be retained in the participant’s account for the subsequent Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 below. Any other amounts left over in a participant’s account after a Purchase Date shall be returned to the participant. 
  
 9. Delivery. The Shares purchased upon exercise of an option hereunder shall be deemed to be transferred to the participant as soon as
administratively practicable on or following the Purchase Date. As promptly as administratively practicable after each Purchase Date of each 
  

 7 

 Offering Period, the Company shall arrange the delivery to each participant, as appropriate, a certificate representing
the Shares purchased upon exercise of his or her option. Notwithstanding the foregoing, the Board may require that all Shares purchased under the Plan be held in an account (the participant’s “ESPP Stock Account”) established
in the name of the participant (or in the name of the participant and his or her spouse, as designated by the participant on his or her subscription agreement), subject to such rules as determined by the Board and uniformly applied to all
participants, including designation of a brokerage or other financial services firm (an “ESPP Broker”) to hold such Shares for the participant’s ESPP Stock Account with registration of such Shares in the name of such ESPP
Broker for the benefit of the participant (or for the benefit of the participant and his or her spouse, as designated by the participant on his or her subscription agreement). 
  
 10. Withdrawal from Plan. 
  
 (a) Withdrawal not in connection with Interruption or Termination of Continuous Service Status.

  
 (i) A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time prior to a Purchase Date by giving written notice to the Company. All of the participant’s Contributions credited to his or her account will be paid to him or her promptly
after receipt of his or her notice of withdrawal and his or her option for the current period will be automatically terminated, and no further Contributions for the purchase of Shares will be made during the Offering Period. With respect to the
First Offering Period, a participant who fails to submit a subscription agreement prior to termination of the Enrollment Period, in accordance with Section 5(a) shall be deemed to have withdrawn from the Plan under this Section 10(a). 
  
 (ii) A participant’s withdrawal from an Offering Period will not have
any effect upon his or her eligibility to participate in a succeeding Offering Period or in any similar plan which may hereafter be adopted by the Company. 
  
 (b) Withdrawal in connection with Interruption or Termination of Continuous Service Status. In the event an Employee fails to remain in
Continuous Service Status during the Offering Period in which he or she is participating, he or she will be deemed to have elected to withdraw from the Plan and any option he or she holds to purchase Shares under the Plan terminated. Upon
termination of a participant’s Continuous Service Status prior to the Purchase Date of an Offering Period for any reason, including death or retirement, the Contributions credited to his or her account will be returned to him or her or, in the
case of his or her death, to the person or persons entitled thereto under Section 13. 
  
 11. Stock. 
  
 (a) Subject to adjustment as provided in Section 17, the maximum number of Shares which shall be made available for sale under the Plan shall be 600,000 Shares, plus an annual increase on the first day of each of the Company’s fiscal
years beginning in 2005 and ending in 2010 equal to the lesser of (i) 300,000 Shares, (ii) one percent (1%) of the Shares 
  

 8 

 outstanding on the last day of the immediately preceding fiscal year, or (iii) such lesser number of Shares as is
determined by the Board. 
  
 (b) If the Board determines that, on
a given Purchase Date, the number of Shares with respect to which options are to be exercised may exceed (i) the number of Shares that were available for sale under the Plan on the Offering Date of the applicable Offering Period, or (ii) the number
of Shares available for sale under the Plan on such Purchase Date, the Board may in its sole discretion provide (x) that the Company shall make a pro rata allocation of the Shares available for purchase on such Offering Date or Purchase Date, as
applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Purchase Date, and continue all Offering Periods
then in effect, or (y) that the Company shall make a pro rata allocation of the Shares available for purchase on such Offering Date or Purchase Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase Common Stock on such Purchase Date, and terminate any or all Offering Periods then in effect pursuant to Section 18 below. The Company may make pro rata allocation of
the Shares available on the Offering Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional Shares for issuance under the Plan by the Company’s stockholders subsequent to such
Offering Date. 
  
 (c) The participant shall have no dividend,
voting or other shareholder rights in Shares covered by any option to acquire Shares under the Plan until such option has been exercised in accordance with Section 8. 
  
 (d) Shares to be delivered to a participant under the Plan will be registered in the name of the participant or in the name
of the participant and his or her spouse; provided that if the Board has determined that Shares shall be held in an ESPP Stock Account held by an ESPP Broker in accordance with Section 9, Shares shall be registered in the name of such ESPP Broker
for the benefit of the participant (or the participant and his or her spouse, as designated by the participant in his or her subscription agreement). 
  
 12. Administration. The Board, or one or more committees named by the Board, shall supervise and administer the Plan and shall have full
power to adopt, amend and rescind any rules deemed desirable and appropriate for the administration of the Plan and not inconsistent with the Plan, to construe and interpret the Plan, and to make all other determinations necessary or advisable for
the administration of the Plan. The Board may, in its sole discretion and on such terms and conditions as it may provide, delegate to one or more individuals all or any part of its authority and powers under the Plan. All determinations,
interpretations, constructions, findings and determinations made by the Board (or its committee or other designee) with respect to the Plan shall be binding on all parties. 
  
 13. Designation of Beneficiary. 
  
 (a) A participant may file a written designation of a beneficiary who is to receive any Shares and cash, if any, from the
participant’s account under the Plan in the event of 
  

 9 

 such participant’s death subsequent to the end of a Purchase Period but prior to delivery to him or her of such
Shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any cash from the participant’s account under the Plan in the event of such participant’s death prior to the Purchase Date of an
Offering Period. If a participant is married and the designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective. Such designation of beneficiary shall be on such form and delivered in such manner
as determined by the Company, and shall be effective upon acknowledgement of receipt by the Company. 
  
 (b) A designation of beneficiary may be changed by the participant (and his or her spouse, if any) at any time by written notice. In the event of the
death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant’s death, the Company shall deliver such Shares and/or cash to the executor or Board of the estate of the
participant, or if no such executor or Board has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such Shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or
if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 
  
 14. Transferability. Neither Contributions credited to a participant’s account nor any rights with regard to the exercise of an option
or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution, or as provided in this Section 14) by the participant. Any such attempt at
assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with Section 10. 
  
 15. Use of Funds. The Company may use all Contributions received or held by the Company under the Plan for any
corporate purpose, and the Company shall not be obligated to segregate such Contributions. 
  
 16. Reports. Individual accounts will be maintained for each participant in the Plan. Statements of account will be given to participating Employees at least annually, which statements will set forth the
amounts of Contributions, the per Share Purchase Price, the number of Shares purchased and the remaining cash balance, if any. 
  
 17. Adjustments Upon Changes in Capitalization; Corporate Transactions. 
  
 (a) Adjustment. Subject to any required action by the
stockholders of the Company, the number of Shares covered by each option under the Plan which has not yet been exercised and the number of Shares which have been authorized for issuance under the Plan but have not yet been placed under option
(collectively, the “Reserves”), as well as the maximum number of Shares which may be purchased by a participant in an Offering Period, the number of Shares set forth in Section 11(a)(i) above, and the per Share Purchase Price
covered by each option under the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock (including any such 
  

 10 

 change in the number of Shares of Common Stock effected in connection with a change in domicile of the Company), or any
other increase or decrease in the number of Shares effected without receipt of consideration by the Company; provided however that conversion of any convertible securities of the Company shall not be deemed to have been “effected without
receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an option. 
  
 (b) Corporate Transactions. 
  
 (i) In the event of a dissolution or liquidation of the Company, any
Offering Period then in progress will terminate immediately prior to the consummation of such action, unless otherwise provided by the Board. In the event of a Corporate Transaction, each option outstanding under the Plan shall be assumed or an
equivalent option shall be substituted by the successor corporation or a parent or Subsidiary of such successor corporation. In the event that the successor corporation refuses to assume or substitute equivalent options for options outstanding under
the Plan, each Offering Period then in progress shall be shortened and a new Purchase Date shall be set (the “New Purchase Date”), as of which date any Offering Period then in progress will terminate. The New Purchase Date shall be
on or before the date of consummation of the Corporate Transaction and the Board shall notify each participant in writing, at least ten (10) days prior to the New Purchase Date, that the Purchase Date for his or her option has been changed to the
New Purchase Date and that his or her option will be exercised automatically on the New Purchase Date, unless prior to such date he or she has withdrawn from the Offering Period as provided in Section 10. 
  
 (ii) For purposes of this Section 17, an option granted under the Plan shall
be deemed to be assumed, without limitation, if, at the time of issuance of the stock or other consideration upon a Corporate Transaction, each holder of an option under the Plan would be entitled to receive upon exercise of the option the same
number and kind of shares of stock or the same amount of property, cash or securities as such holder would have been entitled to receive upon the occurrence of the transaction if the holder had been, immediately prior to the transaction, the holder
of the number of Shares of Common Stock covered by the option at such time (after giving effect to any adjustments in the number of Shares covered by the option as provided for in this Section 17); provided however that if the consideration received
in the transaction is not solely common stock of the successor corporation or its parent (as defined in Section 424(e) of the Code), the Board may, with the consent of the successor corporation, provide for the consideration to be received upon
exercise of the option to be solely common stock of the successor corporation or its parent equal in Fair Market Value to the per share consideration received by holders of Common Stock in the transaction. 
  
 (c) Other Adjustments. The Board may, if it so determines in
the exercise of its sole discretion, also make provision for adjusting the Reserves, as well as the price per Share of Common Stock covered by each outstanding option, in the event that the Company effects one or more reorganizations,
recapitalizations, rights offerings or other increases or reductions of

 18. Amendment or
Termination. 
  
 (a) The Board may at any time and
for any reason terminate or amend the Plan. Except as provided in Section 17 and this Section 18, no such termination of the Plan may affect options previously granted, provided that the Plan or an Offering Period may be terminated by the Board on a
Purchase Date or by the Board’s setting a new Purchase Date with respect to an Offering Period then in progress if the Board determines that termination of the Plan and/or the Offering Period is in the best interests of the Company and its
stockholders, or if continuation of the Plan and/or the Offering Period would cause the Company to incur adverse accounting charges as a result of a change after the effective date of the Plan in the generally accepted accounting rules applicable to
the Plan. Except as provided in Section 17 and in this Section 18, no amendment to the Plan shall make any change in any option previously granted which adversely affects the rights of any participant. In addition, to the extent necessary to comply
with Rule 16b-3 under the Exchange Act, or under Section 423 of the Code (or any successor rule or provision or any other applicable law, regulation or stock exchange rule), the Company shall obtain stockholder approval in such a manner and to such
a degree as so required. 
  
 (b) Without stockholder consent and
without regard to whether any participant rights may be considered to have been adversely affected, the Board (or its committee) shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount of
Contributions withheld from a participant’s Compensation during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated
by a participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that
amounts applied toward the purchase of Common Stock for each participant properly correspond with amounts withheld from the participant’s Compensation, and establish such other limitations or procedures as the Board (or its committee)
determines in its sole discretion advisable which are consistent with the Plan. 
  
 19. Notices. All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the
Company at the location, or by the person, designated by the Company for the receipt thereof. 
  
 20. Conditions Upon Issuance of Shares. Shares shall not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such Shares pursuant thereto shall comply
with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, applicable state securities laws and the
requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. 
  

 12 

 As a condition to the exercise of an option, the Company may require the person exercising such option to
represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation
is required by any of the aforementioned applicable provisions of law. 
  
 21. Term of Plan; Effective Date. The Plan shall become effective upon the IPO Date. It shall continue in effect for a term of twenty (20) years unless sooner terminated under Section 18.

purposes of determining LIBOR for each Interest Period. The Calculation Agent may be removed by the Issuer at any time. If the Calculation Agent is unable or unwilling to act as such or is removed by the Issuer, or if the Calculation Agent fails to
determine LIBOR for an Interest Period, the Issuer shall promptly appoint a replacement Calculation Agent that does not control or is not controlled by or under common control with the Issuer or its Affiliates. The Calculation Agent may not resign
its duties, and the Issuer may not remove the Calculation Agent, without a successor having been duly appointed. 
  
 (b) On each LIBOR Determination Date, the Calculation Agent shall determine LIBOR on the basis of the rate for deposits in United States dollars for a
one-month period which appears on Telerate Page 3750 as of 11:00 a.m., London time, on such date. If such rate does not appear on Telerate Page 3750, the rate for that LIBOR Determination Date shall be determined on the basis of the rates at which
deposits in United States dollars are offered by the Reference Banks at approximately 11:00 a.m., London time, on that day to prime banks in the London interbank market for a one-month period. The Calculation Agent shall request the principal London
office of each of the Reference Banks to provide a quotation of its rate. If at least two such quotations are provided, the rate for that LIBOR Determination Date shall be the arithmetic mean of the quotations. If fewer than two quotations are
provided as requested, the rate for that LIBOR Determination Date will be the arithmetic mean of the rates quoted by four 
  

 7 

 major banks in New York City, selected by the Beneficiary, at approximately 11:00 a.m., New York City time, on that day
for loans in United States dollars to leading European banks for a one-month period. 
  
 (c) The Note Interest Rate applicable to the then current and the immediately preceding Interest Periods may be obtained by telephoning the Indenture Trustee at its corporate trust office at (212) 815-3247 or such
other telephone number as shall be designated by the Indenture Trustee for such purpose by prior written notice by the Indenture Trustee to each Noteholder from time to time. 
  
 (d) On each LIBOR Determination Date, the Calculation Agent shall send to the Indenture Trustee and the Beneficiary, by
facsimile transmission, notification of LIBOR for the following Interest Period. 
  
 Section 2.04. Payments of Interest and Principal. 
  
 (a) Any installment of interest or principal, if any, payable on any Class C(2004-1) Note which is punctually paid or duly provided for by the Issuer and the Indenture Trustee on the applicable Interest Payment Date
or Principal Payment Date shall be paid by the Paying Agent to the Person in whose name such Class C(2004-1) Note (or one or more Predecessor Notes) is registered on the Record Date, by wire transfer of immediately available funds to such
Person’s account as has been designated by written instructions received by the Paying Agent from such Person not later than the close of business on the third Business Day preceding the date of payment or, if no such account has been so
designated, by check mailed first-class, postage prepaid to such Person’s address as it appears on the Note Register on such Record Date, except that with respect to Notes registered on the Record Date in the name of the nominee of Cede &
Co., payment shall be made by wire transfer in immediately available funds to the account designated by such nominee. 
  
 (b) The right of the Class C(2004-1) Noteholders to receive payments from the Issuer will terminate on the first Business Day following the Class
C(2004-1) Termination Date. 
  
 Section 2.05. Targeted Deposit
to the Class C Reserve Account. The deposit targeted to be made to the Class C Reserve sub-Account for the Class C(2004-1) Notes for any Transfer Date will be an amount equal to (i) to the product of (A) Class C Reserve Account Percentage for
the related Monthly Period times (B) the sum of the Initial Outstanding Dollar Principal Amounts of each tranche of Outstanding MBNAseries Notes as of the last day of the preceding Monthly Period times (C) a fraction, the numerator of
which is the Nominal Liquidation Amount of the Class C(2004-1) Notes as of the close of business on the last day of the preceding Monthly Period and the denominator of which is the Nominal Liquidation Amount of all Class C Notes in the MBNAseries as
of the close of business on the last day of the preceding Monthly Period, minus (ii) any amount previously on deposit in the Class C(2004-1) Reserve sub-Account prior to such targeted deposit; provided however, that if an Early
Redemption Event or Event of Default occurs with respect to the Class C(2004-1) Notes, the deposit targeted will be the Adjusted Outstanding Dollar Principal Amount of the Class C(2004-1) notes minus the amount then on deposit in such
sub-Account.
