 OFFERING
PERIODS; OFFERING DOCUMENTS; PURCHASE DATES 
 4.1 Offering Periods. The Administrator may from time to time grant or provide for
the grant of rights to purchase Ordinary Shares under the Plan to Eligible Employees during one or more periods (each, an “Offering Period”) selected by the Administrator. The terms and conditions applicable to each Offering
Period shall be set forth in an “Offering Document” adopted by the Administrator, which Offering Document shall be in such form and shall contain such terms and conditions as the Administrator shall deem appropriate and shall
be incorporated by reference into and made part of the Plan and shall be attached hereto as part of the Plan. The provisions of separate Offering Periods under the Plan need not be identical. 

4.2 Offering Documents . Each Offering Document with respect to an Offering Period shall specify (through incorporation of the
provisions of this Plan by reference or otherwise): 
 (a) the length of the Offering Period, which period shall not exceed twenty-seven
months; 
 (b) the maximum number of Shares that may be purchased by any Eligible Employee during such Offering Period, which, in the
absence of a contrary designation by the Administrator, shall be 25,000 Shares; and 
 (c) such other provisions as the Administrator
determines are appropriate, subject to the Plan. 
 ARTICLE V. 

ELIGIBILITY AND PARTICIPATION 

5.1 Eligibility. Any Eligible Employee who shall be employed by the Company or a Designated Subsidiary on a given Enrollment Date for
an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of this Article V and the limitations imposed by Section 423(b) of the Code. 

5.2 Enrollment in Plan 

(a) Except as otherwise set forth in an Offering Document or determined by the Administrator, an Eligible Employee may become a Participant in
the Plan for an Offering Period by delivering a subscription agreement to the Company by such time prior to the Enrollment Date for such Offering Period (or such other date specified in the Offering Document) designated by the Administrator and in
such form as the Company provides. 
 (b) Each subscription agreement shall designate a whole percentage of such Eligible Employee’s
Compensation to be withheld by the Company or the Designated Subsidiary employing such Eligible Employee on each payday during the Offering Period as payroll deductions under the Plan. The 

  
 5 








 
percentage of Compensation designated by an Eligible Employee may not be less than 1% and may not be more than the maximum percentage specified by the Administrator in the applicable Offering
Document (which percentage shall be 25% in the absence of any such designation) as payroll deductions. The payroll deductions made for each Participant shall be credited to an account for such Participant under the Plan and shall be deposited with
the general funds of the Company. 
 (c) A Participant may increase or decrease the percentage of Compensation designated in his or her
subscription agreement, subject to the limits of this Section 5.2, or may suspend his or her payroll deductions, at any time during an Offering Period; provided, however, that the Administrator may limit the number of changes a
Participant may make to his or her payroll deduction elections during each Offering Period in the applicable Offering Document (and in the absence of any specific designation by the Administrator, a Participant shall be allowed one change to his or
her payroll deduction elections during each Offering Period). Any such change or suspension of payroll deductions shall be effective with the first full payroll period following five business days after the Company’s receipt of the new
subscription agreement (or such shorter or longer period as may be specified by the Administrator in the applicable Offering Document). In the event a Participant suspends his or her payroll deductions, such Participant’s cumulative payroll
deductions prior to the suspension shall remain in his or her account and shall be applied to the purchase of Shares on the next occurring Purchase Date and shall not be paid to such Participant unless he or she withdraws from participation in the
Plan pursuant to Article VII. 
 (d) Except as otherwise set forth in an Offering Document or determined by the Administrator, a
Participant may participate in the Plan only by means of payroll deduction and may not make contributions by lump sum payment for any Offering Period. 

5.3 Payroll Deductions. Except as otherwise provided in the applicable Offering Document, payroll deductions for a Participant shall
commence on the first payroll following the Enrollment Date and shall end on the last payroll in the Offering Period to which the Participant’s authorization is applicable, unless sooner terminated by the Participant as provided in
Article VII or suspended by the Participant or the Administrator as provided in Section 5.2 and Section 5.6, respectively. 

5.4 Effect of Enrollment. A Participant’s completion of a subscription agreement will enroll such Participant in the Plan for each
subsequent Offering Period on the terms contained therein until the Participant either submits a new subscription agreement, withdraws from participation under the Plan as provided in Article VII or otherwise becomes ineligible to participate
in the Plan. 
 5.5 Limitation on Purchase of Ordinary Shares. An Eligible Employee may be granted rights under the Plan only if such
rights, together with any other rights granted to such Eligible Employee under “employee stock purchase plans” of the Company, any Parent or any Subsidiary, as specified by Section 423(b)(8) of the Code, do not permit such
employee’s rights to purchase shares of the Company or any Parent or Subsidiary to accrue at a rate that exceeds $25,000 of the fair market value of such shares (determined as of the first day of the Offering Period during which such rights are
granted) for each calendar year in which such rights are outstanding at any time. This limitation shall be applied in accordance with Section 423(b)(8) of the Code. 

5.6 Decrease or Suspension of Payroll Deductions. Notwithstanding the foregoing, to the extent necessary to comply with
Section 423(b)(8) of the Code and Section 5.5 or the other limitations set forth in this Plan, a Participant’s payroll deductions may be suspended by the Administrator at any time during an Offering Period. The balance of the amount
credited to the account of each Participant that has not been applied to the purchase of Shares by reason of Section 423(b)(8) of the Code, Section 5.5 or the other limitations set forth in this Plan shall be paid to such Participant in
one lump sum in cash as soon as reasonably practicable after the Purchase Date. 

  
 6 








 5.7 Foreign Employees. In order to facilitate participation in the Plan, the Administrator
may provide for such special terms applicable to Participants who are citizens or residents of a non-US jurisdiction, or who are employed by a Designated Subsidiary outside of the United States, as the
Administrator may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Such special terms may not be more favorable than the terms of rights granted under the Plan to Eligible Employees who are residents
of the United States. Moreover, the Administrator may approve such supplements to, or amendments, restatements or alternative versions of, this Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of
this Plan as in effect for any other purpose. No such special terms, supplements, amendments or restatements shall include any provisions that are inconsistent with the terms of this Plan as then in effect unless this Plan could have been amended to
eliminate such inconsistency without further approval by the shareholders of the Company. 
 5.8 Leave of Absence. During leaves of
absence approved by the Company meeting the requirements of Treasury Regulation Section 1.421-1(h)(2) under the Code, a Participant may continue participation in the Plan by making cash payments to the
Company on his or her normal payday equal to his or her authorized payroll deduction. 
 ARTICLE VI. 

GRANT AND EXERCISE OF RIGHTS 

6.1 Grant of Rights. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period shall
be granted a right to purchase the maximum number of Shares specified under Section 4.2, subject to the limits in Section 5.5, and shall have the right to buy, on each Purchase Date during such Offering Period (at the applicable Purchase
Price), such number of whole Shares as is determined by dividing (a) such Participant’s payroll deductions accumulated prior to such Purchase Date and retained in the Participant’s account as of the Purchase Date, by (b) the
applicable Purchase Price (rounded down to the nearest Share). The right shall expire on the last day of the Offering Period. 
 6.2
Exercise of Rights. On each Purchase Date, each Participant’s accumulated payroll deductions and any other additional payments specifically provided for in the applicable Offering Document will be applied to the purchase of whole Shares,
up to the maximum number of Shares permitted pursuant to the terms of the Plan and the applicable Offering Document, at the Purchase Price. No fractional Shares shall be issued upon the exercise of rights granted under the Plan, unless the Offering
Document specifically provides otherwise. Any cash in lieu of fractional Shares remaining after the purchase of whole Shares upon exercise of a purchase right will be credited to a Participant’s account and carried forward and applied toward
the purchase of whole Shares for the next following Offering Period. Shares issued pursuant to the Plan may be evidenced in such manner as the Administrator may determine and may be issued in certificated form or issued pursuant to book-entry
procedures. 
 6.3 Pro Rata Allocation of Shares. If the Administrator determines that, on a given Purchase Date, the number of
Shares with respect to which rights are to be exercised may exceed (a) the number of Shares that were available for issuance under the Plan on the Enrollment Date of the applicable Offering Period, or (b) the number of Shares available for
issuance under the Plan on such Purchase Date, the Administrator may in its sole discretion provide that the Company shall make a pro rata allocation of the Shares available for purchase on such Enrollment 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 

  
 7 








 
Participants for whom rights to purchase Ordinary Shares are to be exercised pursuant to this Article VI on such Purchase Date, and shall either (i) continue all Offering Periods then
in effect, or (ii) terminate any or all Offering Periods then in effect pursuant to Article IX. The Company may make pro rata allocation of the Shares available on the Enrollment 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 shareholders subsequent to such Enrollment Date. The balance of the amount credited to the account of each Participant that
has not been applied to the purchase of Shares shall be paid to such Participant in one lump sum in cash as soon as reasonably practicable after the Purchase Date. 

6.4 Withholding. At the time a Participant’s rights under the Plan are exercised, in whole or in part, or at the time some or all
of the Ordinary Shares 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, that arise upon the exercise of the right or the
disposition of the Ordinary Shares. 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 Ordinary Shares by the Participant.  

6.5 Conditions to Issuance of Ordinary Shares. The Company shall not be required to issue or deliver any certificate or certificates
for, or make any book entries evidencing, Shares purchased upon the exercise of rights under the Plan prior to fulfillment of all of the following conditions: 

(a) The admission of such Shares to listing on all stock exchanges, if any, on which the Ordinary Shares are then listed; 

(b) The completion of any registration or other qualification of such Shares under any state or federal law or under the rulings or
regulations of the Securities and Exchange Commission or any other governmental regulatory body, that the Administrator shall, in its absolute discretion, deem necessary or advisable; 

(c) The obtaining of any approval or other clearance from any state or federal governmental agency that the Administrator shall, in its
absolute discretion, determine to be necessary or advisable; 
 (d) The payment to the Company of all amounts that it is required to
withhold under federal, state or local law upon exercise of the rights, if any; and 
 (e) The lapse of such reasonable period of time
following the exercise of the rights as the Administrator may from time to time establish for reasons of administrative convenience. 

ARTICLE VII. 

WITHDRAWAL; CESSATION OF ELIGIBILITY 

7.1 Withdrawal. A Participant may withdraw all but not less than all of the payroll deductions credited to his or her account and not
yet used to exercise his or her rights under the Plan at any time by giving written notice to the Company in a form acceptable to the Company no later than one week prior to the end of the Offering Period. All of the Participant’s payroll
deductions credited to his or her account during an Offering Period shall be paid to such Participant as soon as reasonably practicable after receipt of notice of withdrawal and such Participant’s rights for the Offering Period shall be
automatically terminated, and no further payroll deductions for the purchase of Shares shall be made for such Offering Period. If a Participant withdraws from an Offering Period, payroll deductions shall not resume at the beginning of the next
Offering Period unless the Participant timely delivers to the Company a new subscription agreement. 

  
 8 








 7.2 Future Participation. A Participant’s withdrawal from an Offering Period shall
not have any effect upon his or her eligibility to participate in any similar plan that may hereafter be adopted by the Company or a Designated Subsidiary or in subsequent Offering Periods that commence after the termination of the Offering Period
from which the Participant withdraws. 
 7.3 Cessation of Eligibility. Upon a Participant’s ceasing to be an Eligible Employee
for any reason, he or she shall be deemed to have elected to withdraw from the Plan pursuant to this Article VII and the payroll deductions credited to such Participant’s account during the Offering Period shall be paid to such Participant
or, in the case of his or her death, to the person or persons entitled thereto under Section 12.4, as soon as reasonably practicable, and such Participant’s rights for the Offering Period shall be automatically terminated. 

ARTICLE VIII. 

ADJUSTMENTS UPON CHANGES IN SHARES 

8.1 Changes in Capitalization. Subject to Section 8.3, in the event that the Administrator determines that any dividend or other
distribution (whether in the form of cash, Ordinary Shares, other securities, or other property), Change in Control, reorganization, merger, amalgamation, consolidation, combination, repurchase, recapitalization, liquidation, dissolution, or sale,
transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Ordinary Shares or other securities of the Company, issuance of warrants or other rights to purchase Ordinary Shares or other
securities of the Company, or other similar corporate transaction or event, as determined by the Administrator, affects the Ordinary Shares such that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any outstanding purchase rights under the Plan, the Administrator shall make equitable adjustments, if any, to reflect
such change with respect to (a) the aggregate number and type of Shares (or other securities or property) that may be issued under the Plan (including, but not limited to, adjustments of the limitations in Section 3.1 and the limitations
established in each Offering Document pursuant to Section 4.2 on the maximum number of Shares that may be purchased); (b) the class(es) and number of Shares and price per Share subject to outstanding rights; and (c) the Purchase Price with
respect to any outstanding rights. 
 8.2 Other Adjustments. Subject to Section 8.3, in the event of any transaction or event
described in Section 8.1 or any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate (including without limitation any Change in
Control), or of changes in Applicable Law or accounting principles, the Administrator, in its discretion, and on such terms and conditions as it deems appropriate, is hereby authorized to take any one or more of the following actions whenever the
Administrator determines that such action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any right under the Plan, to facilitate
such transactions or events or to give effect to such changes in laws, regulations or principles: 
 (a) To provide for either
(i) termination of any outstanding right in exchange for an amount of cash, if any, equal to the amount that would have been obtained upon the exercise of such right had such right been currently exercisable or (ii) the replacement of such
outstanding right with other rights or property selected by the Administrator in its sole discretion; 

  
 9 








 (b) To provide that the outstanding rights under the Plan shall be assumed by the successor or
survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar rights covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and
kind of shares and prices; 
 (c) To make adjustments in the number and type of Shares (or other securities or property) subject to
outstanding rights under the Plan and/or in the terms and conditions of outstanding rights and rights that may be granted in the future; 

(d) To provide that Participants’ accumulated payroll deductions may be used to purchase Ordinary Shares prior to the next occurring
Purchase Date on such date as the Administrator determines in its sole discretion and the Participants’ rights under the ongoing Offering Period(s) shall be terminated; and 

(e) To provide that all outstanding rights shall terminate without being exercised. 

8.3 No Adjustment Under Certain Circumstances. No adjustment or action described in this Article VIII or in any
other provision of the Plan shall be authorized to the extent that such adjustment or action would cause the Plan to fail to satisfy the requirements of Section 423 of the Code. 

8.4 No Other Rights. Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or
consolidation of shares of any class, the payment of any dividend, any increase or decrease in the number of shares of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation. Except as expressly
provided in the Plan or pursuant to action of the Administrator under the Plan, no issuance by the Company of shares of any class, or securities convertible into shares of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number of Shares subject to outstanding rights under the Plan or the Purchase Price with respect to any outstanding rights. 

ARTICLE IX. 
 AMENDMENT,
MODIFICATION AND TERMINATION 
 9.1 Amendment, Modification and Termination. The Administrator may amend, suspend or terminate
the Plan at any time and from time to time; provided, however, that approval of the Company’s shareholders shall be required to amend the Plan to: (a) increase the aggregate number, or change the type, of shares that
may be sold pursuant to rights under the Plan under Section 3.1 (other than an adjustment as provided by Article VIII); (b) change the corporations or classes of corporations whose employees may be granted rights under the Plan; or
(c) change the Plan in any manner that would cause the Plan to no longer be an “employee stock purchase plan” within the meaning of Section 423(b) of the Code. 

9.2 Certain Changes to Plan. Without shareholder consent and without regard to whether any Participant rights may be considered to have
been adversely affected, to the extent permitted by Section 423 of the Code, the Administrator shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld from 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 withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Ordinary Shares for each Participant properly
correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion to be advisable that are consistent with the Plan.

 (a) altering the Purchase Price for any Offering Period including
an Offering Period underway at the time of the change in Purchase Price; 
 (b) shortening any Offering Period so that the Offering Period
ends on a new Purchase Date, including an Offering Period underway at the time of the Administrator action; and

TERM OF PLAN 
 The Plan
shall be effective on the Effective Date. The effectiveness of the Plan shall be subject to approval of the Plan by the shareholders of the Company within twelve months following the date the Plan is first approved by the Board. No right may be
granted under the Plan prior to such shareholder approval. No rights may be granted under the Plan during any period of suspension of the Plan or after termination of the Plan.

ADMINISTRATION 
 11.1
Administrator. Unless otherwise determined by the Board, the Administrator of the Plan shall be the Compensation Committee of the Board (or another committee or a subcommittee of the Board to which the Board delegates administration of the
Plan) (such committee, the “Committee”). The Board may at any time vest in the Board any authority or duties for administration of the Plan. 

11.2 Action by the Administrator. Unless otherwise established by the Board or in any charter of the Administrator, a majority of the
Administrator shall constitute a quorum. The acts of a majority of the members present at any meeting at which a quorum is present and, subject to Applicable Law and the memorandum and articles of association of the Company, acts approved in writing
by a majority of the Administrator in lieu of a meeting, shall be deemed the acts of the Administrator. Each member of the Administrator is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any
officer or other employee of the Company or any Designated Subsidiary, the Company’s independent certified public accountants, or any executive compensation consultant or other professional retained by the Company to assist in the
administration of the Plan.

 11.3 Authority of Administrator. The Administrator shall have the power, subject to, and
within the limitations of, the express provisions of the Plan: 
 (a) To determine when and how rights to purchase Ordinary Shares shall be
granted and the provisions of each offering of such rights (which need not be identical). 
 (b) To designate from time to time which
Subsidiaries of the Company shall be Designated Subsidiaries, which designation may be made without the approval of the shareholders of the Company. 

(c) To construe and interpret the Plan and rights granted under it, and to establish, amend and revoke rules and regulations for its
administration. The Administrator, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective. 

(d) To amend, suspend or terminate the Plan as provided in Article IX. 

(e) Generally, to exercise such powers and to perform such acts as the Administrator deems necessary or expedient to promote the best
interests of the Company and its Subsidiaries and to carry out the intent that the Plan be treated as an “employee stock purchase plan” within the meaning of Section 423 of the Code. 

11.4 Decisions Binding. The Administrator’s interpretation of the Plan, any rights granted pursuant to the Plan, any subscription
agreement and all decisions and determinations by the Administrator with respect to the Plan are final, binding, and conclusive on all parties. 

ARTICLE XII. 

MISCELLANEOUS 
 12.1
Restriction upon Assignment. A right granted under the Plan shall not be transferable other than by will or the applicable laws of descent and distribution, and is exercisable during the Participant’s lifetime only by the
Participant. Except as provided in Section 12.4 hereof, a right under the Plan may not be exercised to any extent except by the Participant. The Company shall not recognize and shall be under no duty to recognize any assignment or alienation of
the Participant’s interest in the Plan, the Participant’s rights under the Plan or any rights thereunder. 
 12.2 Rights as a
Shareholder. With respect to Shares subject to a right granted under the Plan, a Participant shall not be deemed to be a shareholder of the Company, and the Participant shall not have any of the rights or privileges of a shareholder, until such
Shares have been issued to the Participant or his or her nominee following exercise of the Participant’s rights under the Plan. No adjustments shall be made for dividends (ordinary or extraordinary, whether in cash securities, or other
property) or distribution or other rights for which the record date occurs prior to the date of such issuance, except as otherwise expressly provided herein or as determined by the Administrator. 

12.3 Interest. No interest shall accrue on the payroll deductions or contributions of a Participant under the Plan. 

12.4 Designation of Beneficiary. 

(a) A Participant may, in the manner determined by the Administrator, file a written designation of a beneficiary who is to receive any Shares
and/or cash, if any, from the Participant’s 

  
 12 








 
account under the Plan in the event of such Participant’s death subsequent to a Purchase Date on which the Participant’s rights are exercised but prior to delivery to such Participant
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 exercise of the
Participant’s rights under the Plan. If the Participant is married and resides in a community property state, a designation of a person other than the Participant’s spouse as his or her beneficiary shall not be effective without the prior
written consent of the Participant’s spouse. 
 (b) Such designation of beneficiary may be changed by the Participant at any time by
written notice to the Company. 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 administrator of the estate of the Participant, or if no such executor or administrator 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. 

12.5 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. 

12.6 Equal Rights and Privileges. Subject to Section 5.7, all Eligible Employees will have equal rights and privileges under this
Plan so that this Plan qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code. Subject to Section 5.7, any provision of this Plan that is inconsistent with Section 423 of the Code will,
without further act or amendment by the Company, the Board or the Administrator, be reformed to comply with the equal rights and privileges requirement of Section 423 of the Code. 

12.7 Use of Funds. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate
purpose, and the Company shall not be obligated to segregate such payroll deductions. 
 12.8 Reports. Statements of account shall be
given to Participants at least annually, which statements shall set forth the amounts of payroll deductions, the Purchase Price, the number of Shares purchased and the remaining cash balance, if any. 

12.9 No Employment Rights. Nothing in the Plan shall be construed to give any person (including any Eligible Employee or Participant)
the right to remain in the employ of the Company or any Parent or Subsidiary or affect the right of the Company or any Parent or Subsidiary to terminate the employment of any person (including any Eligible Employee or Participant) at any time, with
or without cause. 
 12.10 Notice of Disposition of Shares. Each Participant shall give prompt notice to the Company of any
disposition or other transfer of any Shares purchased upon exercise of a right under the Plan if such disposition or transfer is made: (a) within two years from the Enrollment Date of the Offering Period in which the Shares were purchased or
(b) within one year after the Purchase Date on which such Shares were purchased. Such notice shall specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other
consideration, by the Participant in such disposition or other transfer.

submit any form or notice as set forth herein by means of an electronic form approved by the Administrator. Before the commencement of an Offering Period, the Administrator shall prescribe the time limits within which any such electronic form shall
