3. Demand Registration.

(a) Request for Demand Registration.

Any Designated Holder may, at any time, make a written request to the Company to register, under the Securities Act on any form for which the Company then qualifies and deems appropriate (a Demand Registration), the
number of Registrable Securities stated in such request; provided, however, that the Company shall not be obligated to effect (i) any Demand Registration for less than an aggregate of US$10,000,000 in Registrable Securities,
(ii) more than two (2) Demand Registrations (including any F-3 Registrations pursuant to Section 5 hereof) during any calendar year for any Designated Holder or (iii) in any case, more than four (4) Demand Registrations
(including any F-3 Registrations pursuant to Section 5 hereof) in total under this Agreement, provided, further, that any Designated Holder shall not be entitled to request any Demand Registration after the fourth anniversary of
the date hereof. For purposes of the preceding sentence, two or more Registration Statements filed in response to one demand shall be counted as one Registration Statement. If at the time of any request to register Registrable Securities pursuant to
this Section 3(a), the Board of Directors makes a good faith determination that the filing of such Registration Statement would adversely affect the Company and its shareholders, as a whole, in any material respect, then the Company may at its
option direct that such request be delayed for a reasonable period not in excess of 90 days from the date of receipt of the Demand Registration; provided, however, that the Company shall not exercise such right to delay a request more
than two times or for more than a total of 90 days during any period of 365 days. In addition, the Company shall not be required to effect any registration within 180 days after the effective date of any other Registration Statement of the Company.
Each request for a Demand Registration by the Designated Holder shall state the amount of the Registrable Securities proposed to be sold and the intended method of disposition thereof. Upon a request for a Demand Registration, the Company shall use
its commercially reasonable efforts to promptly take such steps as are necessary or appropriate to prepare for the registration of the Registrable Securities to be registered.

(b) Demand Registration Procedures.

The Company shall use its commercially reasonable efforts to cause any such Demand Registration to become and remain effective not later than 90 days after it receives a request for Demand Registration under Section 3(a). After
receiving a Demand Request under Section 3(a), the Company shall follow the procedures in Section 7. A registration shall not constitute a Demand Registration until it has become effective and remains continuously effective for the lesser
of (i) the period during which all Registrable Securities registered in the Demand Registration are sold and (ii) 90 days; provided, however, that a registration shall not constitute a Demand Registration if (x) after
such Demand Registration has become effective, such registration or the related offer, sale or distribution of Registrable Securities thereunder is interfered with by any stop order, injunction or other order or requirement

of the SEC or other governmental agency or court for any reason not attributable to the Designated Holder and such interference is not thereafter eliminated or
(y) the reasonable and customary conditions specified in the underwriting agreement, if any, entered into in connection with such Demand Registration are not satisfied or waived, other than by reason of a failure by the Designated Holder or the
underwriter(s).

(c) Expenses.

If any registration is initiated by a Designated Holder as a Demand Registration, Giant Haven shall pay all Registration Expenses in connection therewith, whether or not such Demand Registration becomes effective, provided, however, that
the Designated Holder requesting such a Demand Registration shall pay (i) all discounts or underwriter commissions attributable to any Registrable Securities sold by it and (ii) all of its own out-of-pocket expenses, including all legal
fees of the counsel to such requesting Designated Holder in connection with any such registration.

(d) Selection of Underwriters.

(i) If a written request for a Demand Registration is made and the Designated Holder indicates that the applicable
Registrable Securities are to be sold pursuant to an underwritten offering, then the Designated Holder shall select the managing underwriter(s) to administer such offering subject to the written consent of the Company, which consent shall not be
unreasonably withheld.

(ii) If any F-3 Registration or takedown in connection with a Shelf Registration, as the case may
be, of Registrable Securities is in the form of an underwritten offering, the Company shall select an internationally reputable investment banking firm to act as the managing underwriter of the offering (the Approved Underwriter).

4. Incidental or Piggy-Back Registration.

(a) Request for Incidental Registration.

If, at any time, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering by the Company for its own account (other than a Registration Statement on Form F-4 or S-8 or any successor
thereto), then the Company shall give written notice of such proposed filing to each Designated Holder, at least fifteen (15) Business Days before the anticipated filing date, and such notice shall describe the proposed registration and
distribution and offer such Designated Holder the opportunity to register the number of Registrable Securities as such holder may request (an Incidental Registration). No Designated Holder shall be entitled to be named as a
selling securityholder in the Registration Statement, and no Designated Holder shall be entitled to use the prospectus forming a part thereof for resales of Registrable Securities at any time, unless such Designated Holder has responded in writing
indicating such Designated Holders intention to participate in the proposed registration and distribution within five (5) Business Days after such Designated Holders receipt of written notice from the Company. The Company shall, and

shall use its commercially reasonable efforts to cause the managing underwriter or underwriters of a proposed underwritten offering (the Company
Underwriter) to permit a Designated Holder who has requested in writing to participate in the Incidental Registration to include its Registrable Securities in such offering on the same terms and conditions as the securities of the Company
included therein. In connection with any Incidental Registration under this Section 4(a) involving an underwritten offering, the Company shall not be required to include any Registrable Securities in such underwritten offering unless the holder
thereof accepts the terms of the underwritten offering as agreed upon between the Company and the Company Underwriter, and then only in such quantity as will not, in the opinion of the Company Underwriter, have a material adverse effect on the
success of the offering by the Company. If in the written opinion of the Company Underwriter the registration of all or part of the Registrable Securities which one or more Designated Holders have requested to be included would materially adversely
affect the success of such offering, then the Company shall be required to include in such Incidental Registration, to the extent of the amount that the Company Underwriter believes may be sold without causing such adverse effect, first, all of the
securities to be offered for the account of the Company; second, the Registrable Securities to be offered for the account of the Designated Holders pursuant to this Section 4 and Other Registrable Shares, if any, to be offered for the account
of Other Holders requesting incidental or piggy-back registrations in accordance with their registration rights agreements with the Company, if necessary, allocated among the Designated Holders exercising the right to Incidental Registration and
such requesting Other Holders on a pro rata and non-discriminatory basis according to the number of Registrable Securities then outstanding held by each such Designated Holder requesting registration (excluding the Registrable Securities of any
Designated Holder that has chosen not to exercise its right to Incidental Registration) and the number of Other Registrable Securities then outstanding held by each such requesting Other Holder (excluding the Other Registrable Securities of any
Other Holder that has chosen not to request incidental registration under its registration rights agreement with the Company); and third, any other securities requested to be included in such underwritten offering.

(b) Expenses.

The Company shall pay
all Registration Expenses in connection with any Incidental Registration pursuant to this Section 4, whether or not such Incidental Registration becomes effective. The Designated Holders shall pay (i) all discounts or underwriter
commissions attributable to any Registrable Securities sold by them and (ii) all of their own out-of-pocket expenses, including all legal counsel fees in connection with any registration.

5. Form F-3 Registration.

(a)
Request for a Form F-3 Registration.

At any time when the Company is eligible to use Form F-3, in the event that the Company shall
receive from a Designated Holder a written request that the Company register, under the Securities Act, on Form F-3 (or any successor form then in effect)



- 7 -

(an F-3Registration), all or a portion of the Registrable Securities owned by such Designated Holder, the Company shall use its reasonable
best efforts (i) to file a Registration Statement covering the number of shares of Registrable Securities specified in such request on Form F-3 for public sale in accordance with the method of disposition specified in such request within 60
days after the receipt of the Designated Holders request therefor and (ii) to cause such F-3 Registration to be declared effective by the SEC as soon as reasonably practicable thereafter.

(b) Form F-3 Underwriting Procedures.

If the Company or the Designated Holder so elects, the Company shall use its commercially reasonable efforts to cause such F-3 Registration pursuant to this Section 5 to be in the form of a firm commitment underwritten offering and the
managing underwriter or underwriters selected for such offering shall be the Approved Underwriter selected in accordance with Section 3(d)(ii). If the Approved Underwriter advises the Company in writing that in its opinion marketing factors
require a limitation of the aggregate amount of Registrable Securities to be included in the underwritten offering, the Company shall include in such underwritten offering only the aggregate amount of Registrable Securities, on a pro rata basis
according to the number of Registrable Securities then outstanding held by each such Designated Holder requesting registration (excluding the Registrable Securities of any Designated Holder that has chosen not to exercise its right to F-3
Registration), that in the opinion of the Approved Underwriter may be sold without any material adverse effect on the success of such underwritten offering. If Other Holders are entitled to and elect to request for participation in such underwritten
offering to be made upon the election by the Company or the Designated Holder in accordance with this Section 5(b), and if the Approved Underwriter advises the Company in writing that in its opinion marketing factors require a limitation of the
aggregate amount of Registrable Securities and Other Registrable Securities to be included in such underwritten offering, the Company shall include in such underwritten offering only the aggregate amount of Registrable Securities and Other
Registrable Securities, on a pro rata and non-discriminatory basis according to the number of Registrable Securities then outstanding held by each such Designated Holder requesting registration (excluding the Registrable Securities of any Designated
Holder that has chosen not to exercise its right to F-3 Registration) and the number of Other Registrable Securities then outstanding held by each such requesting Other Holder (excluding the Other Registrable Securities of any Other Holder that has
chosen not to request Form F-3 registration under its registration rights agreement with the Company), that in the opinion of the Approved Underwriter may be sold without any material adverse effect on the success of such underwritten offering.

(c) Request for a Shelf Registration.

So long as the Company is eligible to use Form F-3 or such other successor form permitting incorporation of public filing by reference, a Designated Holder shall be entitled, at any time, to request the Company to
file and maintain a Shelf Registration with the SEC under which all or any portion of Common Shares that is owned by it at the time of such request may be resold at any time and from time to time until such time as all such Common Shares are
eligible for sale pursuant to paragraph (k) of Rule 144 (or any successor provision then in effect) or in a single transaction pursuant to paragraph (e) of Rule 144 (or any successor provision then

in effect) under the Securities Act; provided that the aggregate amount of Registrable Securities included in such Shelf Registration as requested by the Designated
Holder is no less than US$10,000,000. The Company shall use its commercially reasonable efforts to cause any such Shelf Registration to become effective. If the Company shall propose to file a registration statement to effect a Shelf Registration
for the offer and sale of Common Shares of any other shareholder of the Company, the Company shall notify each Designated Holder and the Designated Holders shall have the right to require the registration of Registrable Securities under such Shelf
Registration in such amount as it may specify in writing to the Company within fifteen (15) Business Days after receiving notice of such proposed Shelf Registration, only if (i) such notification shall not violate the Companys
obligations to such shareholder of the Company and (ii) the Designated Holders shall obtain written consent of the Approved Underwriter of the takedown in connection with such Shelf Registration. The Company shall not be required to effect a
requested registration as a Shelf Registration if the Board of Directors of the Company shall have determined in good faith that filing such registration at the time of the request would adversely affect the Company and its shareholders, as a whole,
in any material respect, and then the Company may at its option direct that such request be delayed for a reasonable period not in excess of 90 days from the date of receipt of the request of Shelf Registration; provided, however, that
the Company shall not exercise such right to delay a request more than one time or for more than a total of 90 days during any period of 365 days. If the Board of Directors shall have made such a determination with respect to such Shelf
Registration, then the Company will consider to proceed with a Demand Registration or F-3 Registration which is not a Shelf Registration in accordance with Section 3(a) or 5(a), as the case may be, and the Designated Holders may not request
that any subsequent Demand Registration or F-3 Registration be a Shelf Registration until at least 90 days after such determination.

(d)
Companys Election to File a Shelf Registration.

Each Designated Holder agrees that the Company may, at any time at the
Companys option, file a Shelf Registration with the SEC in order to facilitate sales of Common Shares by a Designated Holder. In the event that such a Shelf Registration is declared effective by the SEC, the Company shall use its commercially
reasonable efforts to comply with any request for registration by a Designated Holder under this Agreement by providing an appropriate prospectus supplement under such Shelf Registration. The terms and conditions of this Agreement, including without
limitation, the provisions of Section 5(e), shall apply to the use and availability of such Shelf Registration as if it were the filing of a Registration Statement.

(e) Limitations on Form F-3 Registrations.

If at the time of any request to register Registrable
Securities pursuant to Section 5(a) or any utilization of a Shelf Registration pursuant to Section 5(c) or 5(d), the Board of Directors makes a good faith determination that such request to register Registrable Securities or utilize a
Shelf Registration would be reasonably likely to adversely affect the Company and its shareholders in any material aspect, then the Company may at its option direct that such request or continued availability be delayed for a

reasonable period not in excess of 90 days from the date of receipt of such request; provided, however, that the Company shall not exercise such right to
delay a request more than two times and for more than a total of 90 days during any period of 365 days. In addition, the Company shall not be required to effect any registration pursuant to Section 5(a): (i) if within 180 days after the
effective date of any other Registration Statement of the Company (other than on Form F-4 or S-8), (ii) if within the 12-month period preceding the date of such request, the Company has effected two registrations on Form F-3 pursuant to
Section 5(a) and all of the Registrable Securities registered therein have been sold, or (iii) if Form F-3 is not available for such offering by the relevant Designated Holder.

(f) Expenses.

The Company shall pay
all Registration Expenses in connection with any registration pursuant to Section 5, whether or not such F-3 Registration or the Shelf Registration becomes effective. The Designated Holders shall pay (i) all discounts or underwriter
commissions attributable to any Registrable Securities sold by them and (ii) all of their own out-of-pocket expenses, including all legal counsel fees in connection with any registration.

(g) Demand Registration.

Each
registration requested by a Designated Holder pursuant to this Section 5 shall be deemed a Demand Registration for purposes of Section 3(a)(ii) and Section 3(a)(iii).

6. Restrictions on Public Sale by the Designated Holder.

If, and to the extent, requested by the Approved Underwriter or the Company Underwriter, as the case may be, in the case of an underwritten public offering, a Designated Holder agrees (i) not to effect any public
sale or distribution of any Registrable Securities or of any securities convertible into or exchangeable or exercisable for such Registrable Securities, including a sale pursuant to Rule 144, and (ii) not to make any request for a Demand
Registration, F-3 Registration or Shelf Registration under this Agreement, during a 120-day period or such shorter period agreed upon by such Designated Holder and the requesting party beginning thirty (30) days prior to the anticipated
effective date of the Registration Statement relating to such offering (except as part of such registration).

7. Registration
Procedures.

(a) Obligations of the Company. Whenever registration of Registrable Securities has been requested pursuant to
Section 3, Section 4 or Section 5 of this Agreement, the Company shall:

(i) use its commercially reasonable
efforts to prepare and file, as promptly as practicable, with the SEC a Registration Statement on any form for which the Company then qualifies and which form shall be available for the sale of such Registrable Securities in accordance with the
intended method of distribution thereof, and use its commercially reasonable

covered by such Registration Statement have been sold, or in the case of a Shelf Registration, until such time as the Registrable Securities covered thereby have been sold pursuant to such registration or cease to be deemed Registrable Securities,

Registration Statement and each amendment and supplement thereto (in each case including all exhibits thereto) as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(iv) use its commercially reasonable efforts to register or qualify such Registrable Securities under such other securities
or blue sky laws of such jurisdictions within the United States as any seller of Registrable Securities may reasonably request, and to continue such qualification in effect in such jurisdiction for as long as any such seller reasonably
requests or until all of such Registrable Securities are sold, whichever is shortest, and do any and all other acts and things which may be reasonably necessary or reasonably advisable to enable any such seller to consummate the disposition in such
jurisdictions of the Registrable Securities owned by such seller; provided, however, that the Company shall not be required to (x) qualify generally to do business in any jurisdiction where it would not otherwise be required to
qualify but

required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, and the Company shall use its commercially reasonable efforts to promptly prepare a supplement to or
amendment of such prospectus and furnish to each seller a reasonable number of copies of such supplement to or amendment of such prospectus as may be necessary so that, after delivery to the purchasers of such Registrable Securities, such prospectus
as supplemented or amended shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which
they were made;

(vi) enter into and perform customary agreements (including an underwriting agreement in customary form
with the Approved Underwriter or Company Underwriter, if any, selected as provided in Section 3, Section 4 or Section 5, as the case may be) and take such other reasonable actions as are reasonably prudent and reasonably required in
order to expedite or facilitate the disposition of such Registrable Securities;

(vii) make available at reasonable times

such Records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company, at the Companys expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential;

(viii) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC;

other evidence reasonably satisfactory) that such certificates may be unlegended; provided further, however, that if at a later date for any reason such certificates require that a legend be set forth on the certificates, then such Designated Holder

8. Indemnification and Contribution.

(a) Indemnification by the Company.

The Company agrees to indemnify and hold harmless each Designated Holder and each
Person who controls (within the meaning of Section 15 of the Securities Act) such Designated Holder from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) (collectively,
Damages) incurred by them arising out of or based upon any untrue, or allegedly untrue, statement of a material fact contained in any Registration Statement, prospectus or preliminary prospectus (as amended or supplemented if the
Company shall have furnished any amendments or supplements thereto) or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not
misleading, except insofar as: (i) the same are made in reliance upon, caused by or contained in any information concerning such Designated Holder furnished in writing to the Company by or on behalf of such Designated Holder expressly for use
therein, including, without limitation, the information furnished to the Company pursuant to Section 7(b), or (ii) such Damages would not have occurred but for such Designated Holders continued disposition of Registrable Securities

underwriters (within the meaning of Section 15 of the Securities Act) to the same extent as provided above with respect to the indemnification of the Designated Holder of Registrable Securities.

(b) Indemnification by Designated Holder.

In connection with any Registration Statement in which a Designated Holder is participating pursuant to Section 3, Section 4 or Section 5 hereof, such Designated Holder shall promptly furnish to the Company in writing such
information with respect to such Designated Holder as the Company may reasonably request or as may be required by law for use in connection with any such Registration Statement or prospectus and all information required to be disclosed in order to
make the information previously furnished to the Company by such Designated Holder not materially misleading or necessary to cause such Registration Statement not to omit a material fact with respect to such Designated Holder necessary in order to
make the statements therein not misleading. The Designated Holder agrees to, severally and not jointly with any other Designated Holder, indemnify and hold harmless the Company, any underwriter retained by the Company and each Person who controls
the Company or such underwriter (within the meaning of Section 15 of the Securities Act) to the same extent as the foregoing indemnity from the Company to such Designated Holder, but only with respect to any such information with respect to
such Designated Holder furnished in writing to the Company by or on behalf of such Designated Holder expressly for use therein, including, without limitation, the information furnished to the Company pursuant to this Section 8(b); provided,
however, that the total amount to be indemnified by such Designated Holder pursuant to this Section 8(b) shall be limited to the net proceeds received by such Designated Holder in the offering to which the Registration Statement or prospectus
relates.

(c) Indemnification Procedures.

Promptly after receipt by an indemnified party under this Section 8 (an Indemnified Party) of notice of any claim or the commencement of any action, the Indemnified Party shall, if a claim in respect
thereof is to be made against the indemnifying party under this Section 8 (the Indemnifying Party), notify the Indemnifying Party in writing of the claim or the commencement of that action; provided, however, that the failure
to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have under this Section 8 except to the extent the Indemnifying Party has been materially prejudiced by such failure
and, provided further, that the failure to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to an Indemnified Party otherwise than under this Section 8. If any such
claim or action shall be brought against an Indemnified Party, and it shall notify the Indemnifying Party thereof, the Indemnifying Party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly
notified Indemnifying Party, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or
action, the Indemnifying Party shall not be liable to the Indemnified Party under this Section 8 for any legal and other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs
of investigation; provided, however, that the Company shall have the right to employ counsel to represent jointly the Company and its officers, directors, employees and controlling Persons who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the Company against the Designated Holders under this Section 8 if, in the reasonable judgment of the Company, it is advisable for the Company and its officers, directors, employees and controlling
Persons to be jointly represented by separate counsel, and in that event

the fees and expenses of such separate counsel shall be paid by the Company. No Indemnifying Party shall (i) without the prior written consent of the Indemnified
Parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the Indemnified Parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each Indemnified Party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the
Indemnifying Party or if there be a final judgment of the plaintiff in any such action, the Indemnifying Party agrees to indemnify and hold harmless any Indemnified Party from and against any loss or liability by reason of such settlement or
judgment.

(d) Contribution.

If the indemnification provided for in this Section 8 from the Indemnifying Party is unavailable to an Indemnified Party hereunder in respect of any Damages referred to therein, then the Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Damages in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection
with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative faults of such Indemnifying Party and Indemnified Party shall be determined by reference
to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Sections 8(a),
8(b) and 8(c), any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding; provided, however, that the total amount to be indemnified by the Designated Holder shall be limited to
the net proceeds actually received by such Designated Holder in the offering. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

(e) Survival.

The obligations of the Company and Designated Holders under this Section 9 shall survive the completion of any offering of Registrable Securities in
a Registration Statement, regardless of the expiration of any statutes of limitation or extensions of such statutes.

provided that each Investor may disclose such information to any of its auditors, attorneys and other representatives who agree to be bound by the provisions of this Section 9(b). In the event that an Investor or any Person to whom an Investor
is entitled to disclose information hereunder is required to disclose any Confidential Information in order to comply with any applicable law, regulation, legal or judicial process (by oral questions, interrogatories, requests for information or
documents, subpoena, civil investigation demand or similar process) or stock exchange rule or regulation, the Investor shall in advance of such disclosure provide the Company with prompt notice of such requirement(s) and shall cooperate with the
Company so that the Company may, at its expense, seek a protective order or other appropriate remedy. If, in the absence of a protective order or the receipt of a waiver from the Company after a request in writing therefore is made by an Investor
(such request to be made as soon as reasonably practicable to allow the Company a reasonable amount of time to respond thereto), the Investor or such other Person is legally required to disclose Confidential Information, the Investor or such other
Person may disclose such information without liability hereunder. The term Confidential Information shall not include information (i) which is or becomes publicly available other than as a result of disclosure of such information by an Investor
in violation of this Section 9(b) or any Person to whom an Investor is entitled to disclose such information hereunder, (ii) which is or becomes available to the recipient of such information on a non-confidential basis from a source which
is not, to the recipients knowledge, bound by a confidentiality or other similar agreement or any other legal or fiduciary obligation to the Company or its subsidiaries which prohibits disclosure of such information or (iii) information
that was known by an Investor prior to disclosure by the Company (as evidenced by written records), provided that such information was not known by the Investor to be subject to any legal or contractual obligation of confidentiality owed to the
Company.
