(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder, which terms and
conditions include but are not limited to the exercise or purchase price, the time or times when Awards may vest and/or be exercised (which may be based on performance criteria), the circumstances (if any) when vesting will be accelerated or
forfeiture restrictions will be waived, and any restriction or limitation regarding any Award or Optioned Share; 
 (vi) to amend any
outstanding Award or agreement related to any Optioned Share, including any amendment adjusting vesting (e.g., in connection with a change in the terms or conditions under which such person is providing services to the Company), provided that no
amendment shall be made that would materially and adversely affect the rights of any Participant without his or her consent; 











 (vii) to determine whether and under what circumstances an Option may be settled in cash
under Section 10(c) instead of Common Stock; 
 (viii) subject to Applicable Laws, to implement an Option Exchange Program and

Participant shall be made without his or her consent; 
 (ix) to grant Awards to, or to modify the terms of any outstanding Option Agreement
or any agreement related to any Optioned Share held by, Participants who are foreign nationals or employed outside of the United States with such terms and conditions as the Administrator deems necessary or appropriate to accommodate differences in
local law, tax policy or custom which deviate from the terms and conditions set forth in this Plan to the extent necessary or appropriate to accommodate such differences; and 

(x) to construe and interpret the terms of the Plan, any Option Agreement and any agreement related to any Optioned Share, which
constructions, interpretations and decisions shall be final and binding on all Participants.

cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason
of any action taken or failure to act under the Plan or pursuant to the terms and conditions of any Award except for actions taken in bad faith or failures to act in bad faith, and (ii) any and all amounts paid by him or her in settlement
thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided that such member shall give the Company an opportunity, at its own expense,
to handle and defend any such claim, action, suit or proceeding before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to
which such persons may be entitled under the Company’s Certificate of Incorporation or Bylaws, as in effect from time to time, by contract, as a matter of law, or otherwise, or under any other power that the Company may have to indemnify or
hold harmless each such person. 
 5. Eligibility. 

(a) Recipients of Grants. Nonstatutory Stock Options may be granted to Employees and Consultants and any other individual
specified in the provisions of Section 4(c)(ii) above. Incentive Stock Options may be granted only to Employees, provided that Employees of Affiliates shall not be eligible to receive Incentive Stock Options. 

(b) Type of Option. Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a Nonstatutory
Stock Option. 











 (c) ISO $100,000 Limitation. Notwithstanding any designation under

Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock Options shall be taken into account in the order in which they were
granted, and the Fair Market Value of the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option, and the calculation will be performed in accordance with Section 422 of the Code and the
regulations promulgated thereunder. 
 (d) No Employment Rights. Neither the Plan nor any Award shall confer upon any Employee
or Consultant any right with respect to continuation of an employment or consulting relationship with the Company (any Parent or Subsidiary), nor shall it interfere in any way with such Employee’s or Consultant’s right or the
Company’s (Parent’s or Subsidiary’s) right to terminate his or her employment or consulting relationship at any time, with or without Cause. 

6. Term of Plan. The Plan shall become effective upon its adoption by the Board of Directors. It shall continue in effect
for a term of ten (10) years unless sooner terminated under Section 15 below. 
 7. Term of Option. The term
of each Option shall be the term stated in the Option Agreement; provided that the term shall be no more than seven (7) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement and provided further
that, in the case of an Incentive Stock Option granted to a person who at the time of such grant is a Ten Percent Holder, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in
the Option Agreement. 
 8. Australian scheme. Despite any other rule in this Plan, or any other terms and conditions
governing Awards or Optioned Shares (as contained in any other document or otherwise), Pre-Scheme Awards (as defined in Section 4(c)(ii) above): 

(1) are subject to the terms and conditions contained in this Plan; 

(2) are deemed to have the same grant date which applied to the relevant award in Atlassian Australia (“Equivalent Atlassian Australia
Award”) that was cancelled, and in respect of which such Pre-Scheme Award was provided as consideration by the Company, when the Schemes became effective (as contained in the relevant Option Agreement
of such Equivalent Atlassian Australia Award); 
 (3) have the exercise price and expiry date set out in the relevant Scheme (as defined in
Section 4(c)(ii) above), such exercise price and expiry date being the same as applied to the Equivalent Atlassian Australia Award (as contained in the relevant Option Agreement of such Equivalent Atlassian Australia Award); and 

(4) are deemed to have the same vesting schedule (and any other terms governing vesting, including any terms permitting any acceleration of
vesting) which applied to the Equivalent Atlassian Australia Award prior to the Schemes becoming effective (as contained in the relevant Option Agreement of such Equivalent Atlassian Australia Award), and any unvested
Pre-Scheme Awards will vest in accordance with such vesting schedule and terms. 











 9. Option Exercise Price and Consideration. 

(a) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option shall
be such price as is determined by the Administrator and set forth in the Option Agreement, but shall be subject to the following: 
 (i) In
the case of an Incentive Stock Option 
 (A) granted to an Employee who at the time of grant is a Ten Percent Holder, the per Share exercise
price shall be no less than 110% of the Fair Market Value on the date of grant; 
 (B) granted to any other Employee, the per Share exercise
price shall be no less than 100% of the Fair Market Value on the date of grant; 
 (ii) Except as provided in subsection (iii) below,
in the case of a Nonstatutory Stock Option the per Share exercise price shall be such price as is determined by the Administrator, provided that, if the per Share exercise price is less than 100% of the Fair Market Value on the date of grant, it
shall otherwise comply with all Applicable Laws, including Section 409A of the Code; 
 (iii) In the case of a Nonstatutory Stock
Option that is intended to qualify as performance-based compensation under Section 162(m) of the Code and is granted on or after the date, if ever, on which a share of Common Stock becomes a Listed Security, the per Share exercise price shall
be no less than 100% of the Fair Market Value on the date of grant; and 
 (iv) Notwithstanding the foregoing, Options may be granted with a
per Share exercise price other than as required above pursuant to a merger or other corporate transaction. 
 (b) Permissible
Consideration. The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option and to the extent
required by Applicable Laws, shall be determined at the time of grant) and may consist entirely of (1) cash; (2) check; (3) to the extent permitted under Applicable Laws, delivery of a promissory note with such recourse, interest, security
and redemption provisions as the Administrator determines to be appropriate; (4) cancellation of indebtedness; (5) other previously owned Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price
of the Shares as to which the Option is exercised; (6) a Cashless Exercise; (7) such other consideration and method of payment permitted under Applicable Laws; or (8) any combination of the foregoing methods of payment. In making its
determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company and the Administrator may, in its sole discretion, refuse to accept a
particular form of consideration at the time of any Option exercise. 











 10. Exercise of Option. 

(a) General. 
 (i)
Exercisability. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, consistent with the terms of the Plan and reflected in the Option Agreement, including
vesting requirements and/or performance criteria with respect to the Company, and Parent or Subsidiary, and/or the Optionee. 
 (ii)
Leave of Absence. Vesting of Options shall be tolled during any unpaid leave of absence which is approved by the Company (unless otherwise required by the Applicable Laws). If such leave period includes part of a month, no vesting of
Optionee’s Options will occur for that month. Notwithstanding the foregoing, in the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon a Optionee’s returning from military leave (under
conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have applied had
the Optionee continued to provide services to the Company (or any Parent or Subsidiary, if applicable) throughout the leave on the same terms as he or she was providing services immediately prior to such leave. Vesting of Options may continue during
a period of leave, if Optionee continues to be paid by the Company during such leave. If Optionee is paid a portion of his or her salary during a period of leave, Optionee’s Options will vest over the leave period pro rata to the proportion of
the Optionees’ salary that is paid. 
 (iii) Minimum Exercise Requirements. An Option may not be exercised for a fraction
of a Share. The Administrator may require that an Option be exercised as to a minimum number of Shares, provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then
exercisable. 
 (iv) Procedures for and Results of Exercise. An Option shall be deemed exercised when written notice of such
exercise has been received by the Company in accordance with the terms of the Option Agreement by the person entitled to exercise the Option, the Company has received full payment for the Shares with respect to which the Option is exercised and has
paid, or made arrangements to satisfy, any applicable withholding requirements in accordance with Section 11 below. The exercise of an Option shall result in a decrease in the number of Shares that thereafter may be available, both for purposes
of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (v) Rights as Holder of
Capital Shares. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a holder
of capital shares shall exist with respect to the Optioned Share, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued,
except as provided in Section 13 below. 











 (b) Termination of Employment or Consulting Relationship. The Administrator
shall establish and set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain exercisable, if at all, following termination of an Optionee’s Continuous Service Status, which provisions may be waived
or modified by the Administrator at any time. To the extent that an Option Agreement does not specify the terms and conditions upon which an Option shall terminate upon termination of an Optionee’s Continuous Service Status, the following
provisions shall apply: 
 (i) General Provisions. If the Optionee (or other person entitled to exercise the Option) does not
exercise the Option to the extent so entitled within the time specified below, the Option shall terminate and the Optioned Share underlying the unexercised portion of the Option shall revert to the Plan. In no event may any Option be exercised after
the expiration of the Option term as set forth in the Option Agreement (and subject to Section 7). 
 (ii) Termination other than
Upon Disability or Death or for Cause. In the event of termination of an Optionee’s Continuous Service Status other than under the circumstances set forth in subsections (iii) through (v) below, such Optionee may exercise any
outstanding Option at any time within three (3) months following such termination to the extent the Optionee is vested in the Optioned Share. 

(iii) Disability of Optionee. In the event of termination of an Optionee’s Continuous Service Status as a result of
his or her Disability, such Optionee may exercise any outstanding Option at any time within six (6) months following such termination to the extent the Optionee is vested in the Optioned Share. 

(iv) Death of Optionee. In the event of the death of an Optionee during the period of Continuous Service Status since the date
of grant of any outstanding Option, or within six (6) months following termination of Optionee’s Continuous Service Status, the Option may be exercised by any beneficiary designated in accordance with Section 17 below, or if there are
no such beneficiaries, by the Optionee’s estate, or by a person who acquired the right to exercise the Option by bequest or inheritance, at any time within six (6) months following the date of death or, if earlier, the date the
Optionee’s Continuous Service Status terminated, but only to the extent the Optionee is vested in the Optioned Share. 
 (v)
Termination for Cause. In the event of termination of an Optionee’s Continuous Service Status for Cause, any outstanding Option (including any vested portion thereof) held by such Optionee shall immediately terminate in its
entirety upon first notification to the Optionee of termination of the Optionee’s Continuous Service Status for Cause. If an Optionee’s Continuous Service Status is suspended pending an investigation of whether the Optionee’s
Continuous Service Status will be terminated for Cause, all the Optionee’s rights under any Option, including the right to exercise the Option, shall be suspended during the investigation period. Nothing in this Section 10(b)(v) shall in
any way limit the Company’s right to purchase unvested Shares issued upon exercise of an Option as set forth in the applicable Option Agreement. 

(c) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares an Option previously
granted under the Plan based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made. 











 11. Taxes. 

(a) As a condition of the grant, vesting and exercise of an Award, the Participant (or in the case of the Participant’s death or a
permitted transferee, the person holding or exercising the Award) shall make such arrangements as the Administrator may require for the satisfaction of any applicable U.S. federal, state or local tax withholding obligations or foreign tax
withholding obligations that may arise in connection with such Award. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. 

(b) The Administrator may permit a Participant (or in the case of the Participant’s death or a permitted transferee, the person holding or
exercising the Award) to satisfy all or part of his or her tax withholding obligations by Cashless Exercise or by surrendering Shares (either directly or by stock attestation) that he or she previously acquired; provided that, unless the Cashless
Exercise is an approved broker-assisted Cashless Exercise, the Shares tendered for payment have been previously held for a minimum duration (e.g., to avoid financial accounting charges to the Company’s earnings), or as otherwise permitted to
avoid financial accounting charges under applicable accounting guidance, amounts withheld shall not exceed the amount necessary to satisfy the Company’s tax withholding obligations at the minimum statutory withholding rates, including, but not
limited to, U.S. federal and state income taxes, payroll taxes, and foreign taxes, if applicable. Any payment of taxes by surrendering Shares to the Company may be subject to restrictions, including, but not limited to, any restrictions required by
rules of the Securities and Exchange Commission. 
 12. Non-Transferability of
Options. 
 (a) General. Except as set forth in this Section 12, Options may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution. The designation of a beneficiary by an Optionee will not constitute a transfer. An Option may be exercised, during the lifetime of
the holder of the Option, only by such holder or a transferee permitted by this Section 12. 
 (b) Limited Transferability
Rights. Notwithstanding anything else in this Section 12, the Administrator may in its sole discretion grant Nonstatutory Stock Options that may be transferred by instrument to an inter vivos or testamentary trust in which the Options
are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift to Family Members. Notwithstanding the foregoing, beginning with (i) the period when the Company begins to rely on the exemption described in Rule 12h-1(f)(1) promulgated under the Exchange Act, as determined by the Board in its sole discretion, and (ii) ending on the earlier of (A) the date when the Company ceases to rely on such exemption, as
determined by the Board in its sole discretion, or (B) the date when the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, an Option, or prior to exercise, the Shares subject to the Option,
may not be pledged, hypothecated or otherwise transferred or disposed of, in any manner, including by entering into any short position, any “put equivalent position” or any “call equivalent position” (as defined in Rule 16a-1(h) and Rule 16a-1(b) of the Exchange Act, 











 
respectively), other than to (i) persons who are Family Members through gifts or domestic relations orders, or (ii) to an executor or guardian of the Participant upon the death or
disability of the Participant. Notwithstanding the foregoing sentence, the Board, in its sole discretion, may permit transfers to the Company or in connection with a Corporate Transaction (as defined below) or other acquisition transactions
involving the Company to the extent permitted by Rule 12h-1(f) of the Exchange Act. 
 13.
Adjustments Upon Changes in Capitalization, Merger or Certain Other Transactions and Post-listing Lock-up. 

(a) Changes in Capitalization. Subject to any action required under Applicable Laws by the holders of capital stock of the
Company, (i) the numbers and class of Shares or other stock or securities: (y) available for future Awards under Section 3 above and (z) covered by each outstanding Award, (ii) the price per Share covered by each such
outstanding Option, and (iii) any repurchase price per Share applicable to Shares issued pursuant to any Award, shall be proportionately adjusted by the Administrator in the event of a stock split, reverse stock split, stock dividend,
combination, consolidation, recapitalization (including a recapitalization through a large nonrecurring cash dividend) or reclassification of the Shares, subdivision of the Shares, a rights offering, a reorganization, merger, spin-off, split-up, change in corporate structure or other similar occurrence. Any adjustment by the Administrator pursuant to this Section 13(a) shall be made in the
Administrator’s sole and absolute discretion and shall be final, binding and conclusive. Except as expressly provided herein, no issuance 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 Award. If, by reason of a transaction described in this Section 13(a) or an adjustment pursuant to this
Section 13(a), a Participant’s Award agreement or agreement related to any Optioned Share covers additional or different shares of stock or securities, then such additional or different shares, and the Award agreement or agreement related
to the Optioned Share in respect thereof, shall be subject to all of the terms, conditions and restrictions which were applicable to the Award or Optioned Share prior to such adjustment. Notwithstanding the foregoing, the Administrator shall in any
event make such adjustments as may be required by Section 25102(o) of the California Corporations Code. 
 (b) Dissolution or
Liquidation. In the event of the dissolution or liquidation of the Company, each Award will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 

(c) Corporate Transactions. In the event of a sale of all or substantially all of the Company’s assets, or a merger,
consolidation or other capital reorganization or business combination transaction of the Company with or into another corporation, entity or person (a “Corporate Transaction”), each outstanding Option shall either be
(i) assumed or an equivalent option or right shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”), or (ii) terminated in exchange for a
payment of cash, securities and/or other property equal to the excess of the Fair Market Value of the portion of the Optioned Share that is vested and exercisable immediately prior to the consummation of the Corporate Transaction over the per Share
exercise price thereof. Notwithstanding the foregoing, in the event such Successor Corporation does not agree to such assumption, substitution or exchange, each such Option shall terminate upon the consummation of the Corporate Transaction. 











 14. Time of Granting Options. The date of grant of an Award shall, for
all purposes, be the date on which the Administrator makes the determination granting such Award, or such other date as is determined by the Administrator, provided that in the case of any Incentive Stock Option, the grant date shall be the later of
the date on which the Administrator makes the determination granting such Incentive Stock Option or the date of commencement of the Optionee’s employment relationship with the Company. 

15. Amendment and Termination of the Plan. The Board may at any time amend or terminate the Plan, but no amendment or
termination (other than an adjustment pursuant to Section 13 above) shall be made that would materially and adversely affect the rights of any Participant under any outstanding Award, without his or her consent. In addition, to the extent
necessary and desirable to comply with the Applicable Laws, the Company shall obtain the approval of holders of capital stock with respect to any Plan amendment in such a manner and to such a degree as required. 

16. Conditions Upon Issuance of Shares. Notwithstanding any other provision of the Plan or any agreement entered into by
the Company pursuant to the Plan, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such issuance or delivery would comply with the Applicable Laws, with such compliance
determined by the Company in consultation with its legal counsel. As a condition to the exercise of any Option, the Company may require the person exercising the Option to represent and warrant at the time of any such exercise or purchase 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 Applicable Laws. Shares issued upon exercise of
Options prior to the date, if ever, on which a share of Common Stock becomes a Listed Security shall be subject to a right of first refusal in favor of the Company pursuant to which the Participant will be required to offer Shares to the Company
before selling or transferring them to any third party on such terms and subject to such conditions as is reflected in the applicable Option Agreement. 

17. Beneficiaries. Unless stated otherwise in an Award agreement, a Participant may designate one or more beneficiaries
with respect to an Award by timely filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Participant’s death. If no beneficiary was designated
or if no designated beneficiary survives the Participant, then after a Participant’s death any vested Award(s) shall be transferred or distributed to the Participant’s estate. 

18. Approval of Holders of Capital Stock. If required by the Applicable Laws, continuance of the Plan shall be subject to
approval by the holders of capital stock of the Company within twelve (12) months before or after the date the Plan is adopted or, to the extent required by Applicable Laws, any date the Plan is amended. Such approval shall be obtained in the
manner and to the degree required under the Applicable Laws. 











 19. Addenda. The Administrator may approve such addenda to the Plan as
it may consider necessary or appropriate for the purpose of granting Awards to Employees or Consultants, which Awards may contain such terms and conditions as the Administrator deems necessary or appropriate to accommodate differences in local law,
tax policy or custom, which, if so required under Applicable Laws, may deviate from the terms and conditions set forth in this Plan. The terms of any such addenda shall supersede the terms of the Plan to the extent necessary to accommodate such
differences but shall not otherwise affect the terms of the Plan as in effect for any other purpose. 
 20. Information to
Participants. Beginning on the earlier of (i) the date that the aggregate number of Participants under this Plan is five hundred (500) or more and the Company is relying on the exemption provided by Rule 12h-1(f)(1) under the Exchange Act, and (ii) the date that the Company is required to deliver information to Participants pursuant to Rule 701 under the Securities Act, and until such time as the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, is no longer relying on the exemption provided by Rule 12h-1(f)(1) under the Exchange Act or is no longer required
to deliver information to Participants pursuant to Rule 701 under the Securities Act, the Company shall provide to each Participant the information described in paragraphs (e)(3), (4), and (5) of Rule 701 under the Securities Act not less
frequently than every six (6) months with the financial statements being not more than one hundred and eighty (180) days old and with such information provided either by physical or electronic delivery to the Participants or by written
notice to the Participants of the availability of the information on an Internet site that may be password-protected and of any password needed to access the information. The Company may request that Participants agree to keep the information to be
provided pursuant to this section confidential. If a Participant does not agree to keep the information to be provided pursuant to this section confidential, then the Company will not be required to provide the information unless otherwise required
pursuant to Rule 12h-1(f)(1) under the Exchange Act or Rule 701 of the Securities Act. 











 ADDENDUM A 

ATLASSIAN CORPORATION PTY LIMITED 2010 U.S. SHARE OPTION PLAN 

(California Participants) 
 Prior
to the date, if ever, on which a share of Common Stock becomes a Listed Security and/or the Company is subject to the reporting requirements of the Exchange Act, the terms set forth herein shall apply to Awards issued to California Participants. All
capitalized terms used herein but not otherwise defined shall have the respective meanings set forth in the Plan. 
 1. The following rules
shall apply to any Option in the event of termination of the Participant’s Continuous Service Status: 
 a. If such termination was for
reasons other than death, “disability” (as defined below), or Cause, the Participant shall have until the earlier of (i) the expiration of the Option term as set forth in the Option Agreement or (ii) at least thirty
(30) days after the date of such termination to exercise his or her Option to the extent the Participant is entitled to exercise on his or her termination date. 

b. If such termination was due to death or disability, the Participant shall have until the earlier of (i) the expiration of the Option
term as set forth in the Option Agreement or (ii) at least six (6) months after the date of such termination to exercise his or her Option to the extent the Participant is entitled to exercise on his or her termination date. 

“Disability” for purposes of this Addendum shall mean the inability of the Participant, in the opinion of a qualified physician acceptable to the
Company, to perform the major duties of the Participant’s position with the Company or any Parent or Subsidiary because of the sickness of injury of the Participant. 

2. Notwithstanding anything stated herein to the contrary, no Option shall be exercisable on or after the tenth anniversary of the date of
grant and any Award agreement shall terminate on or before the tenth anniversary of the date of grant. 
 3. The Company shall furnish
summary financial information (audited or unaudited) of the Company’s financial condition and results of operations, consistent with the requirements of Applicable Laws, at least annually to each California Participant during the period such
Participant has one or more Awards outstanding, and in the case of an individual who acquired Shares pursuant to the Plan, during the period such Participant owns such Shares. The Company shall not be required to provide such information if
(i) the issuance is limited to key employees whose duties in connection with the Company assure their access to equivalent information or (ii) the Plan or any agreement complies with all conditions of Rule 701 of the Securities Act;
provided that for purposes of determining such compliance, any registered domestic partner shall be considered a “family member” as that term is defined in Rule 701.
