	3.	RIGHTS OF REFUSAL 

  

	 	(a)	Transfer Notice 

If at any time a Holder (the “Selling Holder”) proposes to Transfer Equity Securities and has received a firm offer from
prospective transferee(s), the Selling Holder shall give the Company and all the other Holders (“Entitled Holders”) written notice of the Selling Holder’s intention to make the Transfer (the “Transfer Notice”).
The Transfer Notice shall include (i) a description of the Equity Securities to be transferred (the “Offered Shares”), (ii) the identity of the prospective transferee(s) and (iii) the consideration and the material
terms and conditions upon which the proposed Transfer is to be made. The Transfer Notice shall certify that the Selling Holder has received a firm offer from the prospective transferee(s) and in good faith believes a binding agreement for the
Transfer is obtainable on the terms set forth in the Transfer Notice. The Transfer Notice shall also include a copy of any written proposal, term sheet or letter of intent or other agreement relating to the proposed Transfer. 

 

	 	(b)	Holders’ Right of First Refusal 

  

	 	(i)	Each Entitled Holder shall have an option for a period of fourteen (14) days from receipt of the Transfer Notice to elect to purchase the Offered Shares at the
same price and subject to the same material terms and conditions as described in the Transfer Notice. Each Entitled Holder may exercise such purchase option and, thereby, purchase all or any portion of the Offered Shares by notifying the Selling
Holder in writing before expiration of such fourteen (14) day period as to the number of such shares which such Entitled Holder (a “Participating Holder”) wishes to purchase. To the extent one or more Entitled Holders exercise
such purchase option, the number of Offered Shares that such Entitled Holder may purchase shall be correspondingly reduced to such Entitled Holder’s pro rata share of the Offered Shares. Each Entitled Holder’s “pro rata
share” of the Offered Shares shall be a fraction of the Offered Shares, of which the number of Ordinary Shares (including Ordinary Shares issuable upon conversion of Preferred Shares) owned by such Entitled Holder on the date of the
Transfer Notice shall be the numerator and the total number of Ordinary Shares (including Ordinary Shares issuable upon conversion of Preferred Shares) held by all Entitled Holders on the date of the Transfer Notice shall be the denominator.

  
 9 

	 	(ii)	In the event any Entitled Holder elects not to purchase its pro rata share of the Offered Shares available pursuant to its rights under Section 3(b)(i)
within the time period set forth therein, then the Selling Holder shall promptly give written notice to each of the Participating Holders (the “Overallotment Notice”), which shall set forth the number of Offered Shares not purchased
by the other Entitled Holders, and shall offer the Participating Holders the right to acquire the unsubscribed shares. Each Participating Holder shall have seven (7) days after receipt of the Overallotment Notice to deliver a written notice to
the Selling Holder of its election to purchase its pro rata share of the unsubscribed shares on the same terms and conditions as set forth in the Transfer Notice. For the purposes of this Section 3(b)(ii), the denominator described in
subsection (i) of this Section 3(b) shall be the total number of Ordinary Shares (including Ordinary Shares issuable upon conversion of the Preferred Shares) owned by all Participating Holders on the date of the Transfer Notice.

  

	 	(iii)	Each Participating Holder which is a venture capital fund shall be entitled to apportion the shares to be purchased among its partners, members, Affiliates and related
parties (including other venture capital funds affiliated with such fund), provided that such Participating Holder notifies the Selling Holder of such allocation. 

 

	 	(iv)	The Participating Holders shall effect the purchase of the Offered Shares with payment by check or wire transfer, against delivery of the Offered Shares, to be
purchased at a place agreed upon between the parties and at the time of the scheduled closing therefor, which shall be no later than forty five (45) days after receipt by the Entitled Holders of the Transfer Notice, unless the Transfer Notice
contemplated a later closing with the prospective third-party transferee(s) or unless the value of the purchase price has not yet been established pursuant to Section 3(e). 

 

	 	(c)	Additional Transfer Notice 

 Subject to the Entitled Holders’ rights set forth in Section 3(b), if at any time a Selling Holder proposes a Transfer, then, after the Entitled Holders have declined to purchase all or
any portion of the Offered Shares, the Selling Holder shall give the Company an “Additional Transfer Notice” which shall include all of the information and certifications required in a Transfer Notice and shall additionally identify
the Offered Shares which the Entitled Holders have declined to purchase (the “Remaining Shares”). 
  

	 	(d)	Company’s Right of First Refusal 

  

	 	(i)	The Company shall have an option, subject to compliance of applicable law for a period of fourteen (14) days from the Company’s receipt of the Additional
Transfer Notice from the Selling Holder to elect to purchase all or any portion of the Remaining Shares subject to the same material terms and conditions as described in the Additional Transfer Notice, by notifying the Selling Holder in writing,
before expiration of the fourteen (14) day period as to the number of such shares which the Company wishes to purchase. 

  
 10 

	 	(ii)	If the Company gives the Selling Holder notice that it desires to purchase such shares, then payment for the Remaining Shares shall be by check or wire transfer,
against delivery of the Remaining Shares to be purchased, at a place agreed upon between the parties and at the time of the scheduled closing therefor, which shall be no later than forty five (45) days after receipt by the Company of the
Additional Transfer Notice, unless the Additional Transfer Notice contemplated a later closing with the prospective third-party transferee(s) or unless the value of the purchase price has not yet been established pursuant to
Section 3(e). 

  

	 	(e)	Valuation of Property 

 Should the purchase price specified in the Transfer Notice or Additional Transfer Notice be payable in property other than cash or evidences of indebtedness, the Participating Holders (or the Company, as
the case may be) shall have the right to pay the purchase price in the form of cash equal in amount to the value of such property. If the Selling Holder and the Participating Holders (or the Company, as the case may be) cannot agree on such cash
value within ten (10) days after the Participating Holders’ receipt of the Transfer Notice (or the Company’s receipt of the Additional Transfer Notice), the valuation shall be made by an appraiser of recognized standing selected by
the Selling Holder and the Participating Holders (or the Company, as the case may be) or, if they cannot agree on an appraiser within twenty (20) days after the Participating Holders’ receipt of the Transfer Notice (or the Company’s
receipt of the Additional Transfer Notice), each shall select an appraiser of recognized standing and the two appraisers shall designate a third appraiser of recognized standing, whose appraisal shall be determinative of such value. The cost of such
appraisal shall be shared equally by the Selling Holder and the Participating Holders (and/or the Company, as the case may be), with that portion of the cost borne by the Participating Holders (and/or the Company, as the case may be) borne pro rata
by each based on the number of shares such parties were interested in purchasing pursuant to this Section 3. If the time for the closing of the Participating Holders’ purchase or the Company’s purchase has expired but for the
determination of the value of the purchase price offered by the prospective transferee(s), then such closing shall be held on or prior to the third business day after such valuation shall have been made pursuant to this subsection. 

 

	4.	RIGHTS OF CO-SALE 

  

	 	(a)	To the extent the Company and the Entitled Holders do not exercise their respective rights of refusal as to all of the Offered Shares pursuant to Section 3,
then each holder of any Preferred Share (a “Co-Selling Holder” for purposes of this Section 4) that notifies the Selling Holder in writing within thirty (30) days after receipt of the Transfer Notice referred to in
Section 3(a), shall have the right to participate in such sale of Equity Securities to the prospective transferee identified in the Transfer Notice and on the same terms and conditions as specified in such Transfer Notice. Such
Co-Selling Holder’s notice to the Selling Holder shall indicate the number of shares of Equity Securities the Co-Selling Holder wishes to sell under such Co-Selling Holder’s right to participate. This right of co-sale shall not apply with
respect to Offered Shares sold or to be sold to Participating Holders and/or the Company pursuant to Section 3. 

  
 11 

	 	(b)	Each Co-Selling Holder may sell all or any part of that number of shares of Equity Securities equal to the product obtained by multiplying (i) the aggregate number
of shares of Equity Securities covered by the Transfer Notice and not sold pursuant to Section 3 by (ii) a fraction, the numerator of which is the number of Ordinary Shares (including Ordinary Shares issuable upon conversion of the
Preferred Shares) owned by the Co-Selling Holder on the date of the Transfer Notice and the denominator of which is the total number of Ordinary Shares (including Ordinary Shares issuable upon conversion of the Preferred Shares) owned by the Selling
Holder and all of the Co-Selling Holders on the date of the Transfer Notice, up to a maximum number equal to the number of Offered Shares indicated in the Transfer Notice under Section 3 minus the number of shares of Equity Securities to
be purchased by the Company and the other Participating Holders pursuant to Section 3. 

  

	 	(c)	Each Co-Selling Holder shall effect its participation in the sale by promptly delivering to the Selling Holder for transfer to the prospective transferee one or more
share certificates together with the duly executed instrument of transfer thereof), which represent: 

  

	 	(i)	the type and number of shares of Equity Securities which such Co-Selling Holder elects to sell; or 

 

	 	(ii)	that number of shares of Equity Securities that are at such time convertible into the number of Ordinary Shares which such Co-Selling Holder elects to sell;
provided, however, that, in the case of Preferred Shares, if the prospective third-party transferee objects to the delivery of Preferred Shares in lieu of Ordinary Shares, such Co-Selling Holder shall convert such Preferred Shares into
Ordinary Shares and deliver Ordinary Shares as provided in this subsection (c). The Company agrees to make any such conversion concurrent with the actual transfer of such shares to the transferee and contingent on such transfer.

  

	 	(d)	The share certificate or certificates (together with the duly executed instrument of transfer thereof) that the Co-Selling Holder delivers to the Selling Holder
pursuant to subsection (c) above shall be transferred to the prospective transferee in consummation of the sale of the Equity Securities pursuant to the terms and conditions specified in the Transfer Notice, and the Selling Holder shall
concurrently therewith remit to such Co-Selling Holder that portion of the sale proceeds to which such Co-Selling Holder is entitled by reason of its participation in such sale. To the extent that any prospective transferee or transferees prohibits
such assignment or otherwise refuses to purchase shares or other securities from a Co-Selling Holder exercising its rights of co-sale hereunder, the Selling Holder shall not sell to such prospective transferee or transferees any Equity Securities
unless and until, simultaneously with such sale, the Selling Holder shall purchase such shares or other securities from such Co-Selling Holder for the same consideration and on the same terms and conditions as the proposed transfer described in the
Transfer Notice. 

  
 12 

	5.	RIGHTS AS A HOLDER 

  

	 	(a)	Any Transfer between Holders (or between a Holder and the Company, as the case may be) pursuant to this Agreement shall be effected by the transferor selling as
beneficial owner of the relevant Equity Securities free and clear of all liens, charges and encumbrances, and together with all rights attaching thereto. 

  

	 	(b)	If the Company or any Participating Holder exercises its right of refusal to purchase the Offered Shares, then, upon the date that the notice of such exercise by the
Company or any Participating Holder is deemed delivered to the Selling Holder, the Selling Holder will have the right to receive payment for the Offered Shares from the Company or such Participating Holder, as the case may be, in accordance with the
terms of this Agreement, and the Selling Holder will forthwith cause all certificate(s) evidencing such Offered Shares (together with the duly executed instrument of transfer thereof) to be surrendered for Transfer to the Company or such
Participating Holder, as the case may be. 

  

	6.	NON-EXERCISE OF RIGHTS 

  

	 	(a)	To the extent that the Company and the Entitled Holders have not exercised their rights to purchase the Offered Shares within the time periods specified in
Section 3 and the holder(s) of Preferred Shares has not exercised its rights to participate in the sale of the Equity Securities within the time periods specified in Section 4, the Selling Holder shall have a period of thirty
(30) days from the expiration of such rights in which to sell the Remaining Shares upon terms and conditions (including the purchase price) no more favorable than those specified in the Transfer Notice to the third-party transferee(s)
identified in the Transfer Notice. In the event the Selling Holder does not consummate the sale or disposition of the Remaining Shares within the thirty (30) day period from the expiration of these rights, the Company and the Entitled
Holders’ refusal rights and the co-sale rights of the Holder(s) of Preferred Shares shall continue to be applicable to any subsequent disposition of the Offered Shares or the Remaining Shares by the Selling Holder until such right lapses in
accordance with the terms of this Agreement. Furthermore, the exercise or non-exercise of the rights of the Company and the Entitled Holders under this Agreement to purchase Equity Securities from the Selling Holder, or the exercise or non-exercise
of the rights of the holder(s) of Preferred Shares to participate in sales of Equity Securities by the Selling Holder, shall not adversely affect their rights to make subsequent purchases from the Selling Holder of Equity Securities or subsequently
participate in sales of Equity Securities by the Selling Holder. 

  

	 	(b)	Any third-party transferee (if not already bound by the provisions of this Agreement) acquiring Equity Securities from any Holder pursuant to the provision of this
Agreement (including Section 9) shall execute and deliver a deed of adherence whereupon such transferee shall be bound by and shall be entitled to the benefit of this Agreement as if it were an original party and “Holder” and
(i) in the event of Ordinary Shares being acquired from an Existing Shareholder, “Existing Shareholder” hereunder or (ii) in the event of Preferred Shares being acquired from a Preferred Shareholder “Preferred
Shareholder” hereunder. 

  
 13 

	7.	PROHIBITED TRANSFERS 

  

	 	(a)	In the event the Selling Holder should sell any Equity Securities in contravention of the co-sale rights of the Co-Selling Holders under Section 4 (a
“Prohibited Transfer”), the Co-Selling Holders, in addition to such other remedies as may be available at law, in equity or hereunder, shall have the right provided in Section 7(b) below, and the Selling Holder shall be
bound by the applicable provisions of such right. 

  

	 	(b)	In the event of a Prohibited Transfer, a Co-Selling Holder shall have the right to sell to the Selling Holder the type and number of shares of Equity Securities equal
to the number of shares such Co-Selling Holder would have been entitled to transfer to the third-party transferee(s) under Section 4 hereof had the Prohibited Transfer been effected pursuant to and in compliance with the terms hereof.
Such sale shall be made on the following terms and conditions:

Holder’s rights under Section 4.

in such proportions as it deems appropriate. For purposes of this Section 12 only, “Pro Rata Share” shall mean the ratio of (x) the number of Ordinary Shares (including Ordinary Shares issuable upon conversion of

 Each time the Company proposes to offer any shares of, or securities convertible into or exchangeable or exercisable for any shares of, any class of its share capital (“New Shares”), the
Company shall first make an offering of such New Shares to all the Holders in accordance with the following provisions.

intention to offer such New Shares, (ii) the number of such New Shares to be offered, and (iii) the price and terms upon which it proposes to offer such New Shares.

	 	(b)	By written notification received by the Company, within twenty (20) calendar days after receipt of the Offer Notice, a Holder may elect to purchase, at the price
and on the terms specified in the Offer Notice, up to such Holder’s Pro Rata Share. If a Holder elects not to exercise its right to purchase such New Shares (the “Unsubscribed Shares”) within such 20-day period, the Company
shall promptly inform in writing those Holders who elect to exercise their rights to purchase and such Holders will have an additional seven (7) days to exercise an over allotment right to purchase the remaining Unsubscribed Shares, according
to their Pro Rata Share. 

  

	 	(c)	If all New Shares referred to in the Offer Notice that the Holders are entitled to purchase pursuant to this Section 12 are not elected to be purchased as
provided therein, the Company may, during the 60-day period following the expiration of the period provided in Section 12(b), offer the Unsubscribed Shares that were not purchased, either directly or indirectly or by virtue of an
exercise of the over allotment right the Holders have pursuant to this Section 12 to any person or persons at a price not less than, and upon terms no more favorable to the offeree than those specified in the Offer Notice. If the Company
does not enter into an agreement for the sale of the New Shares within such period, or if such agreement is not consummated within ninety (90) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such
New Shares shall not be offered unless first reoffered to all the Holders in accordance herewith.

already bound by the provisions of this Agreement) shall execute and deliver a deed of adherence whereupon such person or persons shall be bound by and shall be entitled to the benefit of this Agreement as if it were an original party and Holder

grants, option plans, purchase plans or other employee share incentive programs or arrangements approved in accordance with the provisions of this Agreement;

Preferred Shareholders’ tax advisors determine that the Preferred Shareholders’ interest in the Company is subject to any such reporting requirements, the Company agrees, upon a request from such Preferred Shareholder, to provide such
information to such Preferred Shareholder as may be necessary to fulfill such Preferred Shareholder’s obligations thereunder. 

  

	 	(l)	The Company shall use its commercially reasonable efforts to minimize its risk of being, or becoming, classified as a “passive foreign investment company” (a
“PFIC”) within the meaning of Section 1297 of the Code. The Company shall make due inquiry with its tax advisors on at least an annual basis regarding its status as a PFIC, and if the Company is informed by its tax advisors that it
has become a PFIC, or that there is a likelihood of the Company being classified as a PFIC for any taxable year, the Company shall promptly notify the Preferred Shareholders of such status or risk, as the case may be. In connection with a
“Qualified Electing Fund” election made by a Preferred Shareholder pursuant to Section 1295 of the United States Internal Revenue Code or a “Protective Statement” filed by a Preferred Shareholder pursuant to Treasury
Regulation Section 1.1295-3, as amended (or any successor thereto), the Company shall provide annual financial information to the Preferred Shareholder in the form attached hereto as Exhibit E as soon as reasonably practicable following
the end of each taxable year of such Preferred Shareholder (but in no event later than 90 days following the end of each such taxable year), and shall provide such Preferred Shareholder with access to such other Company information as may be
required for purposes of filing U.S. federal income tax returns in connection with such Qualified Electing Fund election or Protective Statement.

	 	(m)	The Company shall not, without the written consent of a Preferred Shareholder, issue or transfer securities in the Company to such Preferred Shareholder if following
such issuance or transfer the Company, in the determination of counsel or accountants for such Preferred Shareholder, would be a controlled foreign corporation (a “CFC”) as defined in Section 957 of the Code with respect to the
securities held by such Preferred Shareholder. The Company shall make due inquiry with its tax advisors on at least an annual basis regarding its status as a CFC and regarding whether any portion of the Company’s income is Subpart F income. In
the event that Company is determined by the Company’s tax advisors or by counsel or accountants for any Preferred Shareholder to be a CFC with respect to the securities held by such Preferred Shareholder, the Company agrees to use commercially
reasonable efforts to avoid generating Subpart F income. 

  

	 	(n)	For purposes of paragraphs (i) through (iii) of this Section 18(n): 

 

	 	(1)	“U.S. Investor” means (A) any Preferred Shareholder that is a United States person and (B) any Preferred Shareholder that is an entity

its subsidiaries to permit such U.S. Investor to (i) accurately prepare all tax returns and comply with any reporting requirements and (ii) make any election, with respect to the Company or any of its direct or indirect subsidiaries, and
comply with any reporting or other requirements incident to such election. 

  

	 	(iii)	The Company shall: furnish to each U.S. Investor upon its reasonable request, on a timely basis, and at the Company’s expense, all information reasonably necessary
to satisfy the U.S. income tax return filing requirements of such U.S. Investor (or such other person that owns any direct or indirect interest in such U.S. Investor) arising from its investment in the Company. 

  
 27 

	 	(o)	The Company shall not, and the Founders shall cause the Company and any other persons or entities directly or indirectly Controlled by them not to, and the Company
shall ensure that the Company’s subsidiaries (including any Subsidiary) and their respective officers, directors, and representatives shall not, in violation of any applicable law and regulations, make, directly or indirectly, any payment, loan
or gift of any money, or anything of value to, or for the use of, any government official (including an official of a government-owned or controlled entity), any political party or official, or any candidate for political office, or any other person
where it knows or has reason to know that such payment, loan or gift would be given directly or indirectly to any government official or political party or official candidate, and they shall not, in violation of any applicable law and regulation,
take any action or make any payment (including promises to take action or make payments), in each case for the purpose of inducing any of the foregoing persons to do any act to make any decisions in his or its official capacity (including a decision
to fail to perform his or its official function) or use his or its influence with a government or instrumentality in order to affect any act or decision of such government or instrumentality in order to assist the Company or any Preferred
Shareholder or their respective subsidiaries in obtaining or retaining any business or to obtain an unfair competitive advantage or which may cause the Company or any Preferred Shareholder or their respective subsidiaries to be in violation of, any
applicable laws and regulations. Notwithstanding anything to the contrary in this Section 18(m), any facilitating or expediting payment made to a government official for the purpose of expediting or securing the performance of a routine
governmental action by a government official shall not constitute a breach of the covenant made in this Section 18(i). 

  

	 	(p)	The Company shall ensure that each Group Company is in full compliance with United States and international economic and trade sanctions, including those administered
by the Office of Foreign Assets Control of the United States Department of the Treasury. Without limiting the generality of the foregoing, the Company shall insure that (i) no officer, director or employee of the Company or any Subsidiary or
any Affiliate thereof shall entered into any transaction with, or for the benefit of, any of the individuals or institutions named on lists of sanctioned persons, including the Office of Foreign Assets Control of the United States Department of the

 EXHIBIT E – PFIC QUESTIONNAIRE 

 

	(1)	This questionnaire applies to the taxable year of 21ViaNet Group, Inc. (“Company”) beginning on January 1,
[        ], and ending on December 31, [        ]. 

  

	(2)	PLEASE CHECK HERE IF 75% OR MORE OF THE
COMPANY’S GROSS INCOME CONSTITUTES PASSIVE INCOME. 

 Passive income: For purposes of this test, passive income includes: 
  

	 	•	 	 Dividends, interests, royalties, rents and annuities, excluding, however, rents and royalties which are received from an unrelated party in
connection with the active conduct of a trade or business. 

  

	 	•	 	 Net gains from the sale or exchange of property— 

 

	 	•	 	 which gives rise to dividends, interest, rents or annuities (excluding, however, property used in the conduct of a banking, finance or similar
business, or in the conduct of an insurance business); 

  

	 	•	 	 which is an interest in a trust, partnership, or REMIC; or 

 

	 	•	 	 which does not give rise to income. 

  

	 	•	 	 Net gains from transactions in commodities. 

  

	 	•	 	 Net foreign currency gains. 

  

	 	•	 	 Any income equivalent to interest. 

 Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by value of another corporation, the Company must take into account its proportionate share of the income received by such
other corporation. 
  

	(3)	PLEASE CHECK HERE IF THE AVERAGE FAIR MARKET
VALUE DURING THE TAXABLE YEAR OF PASSIVE ASSETS HELD BY THE COMPANY
EQUALS 50% OR MORE OF THE AVERAGE FAIR MARKET VALUE OF ALL OF
THE COMPANY’S ASSETS. 

 Note: This test is
applied on a gross basis; no liabilities are taken into account. 
 Passive Assets: For purposes of this test, “passive
assets” are those assets which generate (or are reasonably expected to generate) passive income (as defined above). Assets which generate partly passive and partly non-passive income are considered passive assets to the extent of the relative
proportion of passive income (compared to non-passive income) generated in a particular taxable year by such assets. Please note the following: 
  

	 	•	 	 A trade or service receivable is non-passive if it results from sales or services provided in the ordinary course of business.

  
 63 

	 	•	 	 Intangible assets that produce identifiable items of income, such as patents or licenses, are characterized in terms of the type of income produced.

  

	 	•	 	 Goodwill and going concern value must be identified to a specific income producing activity and are characterized in accordance with the nature of that
activity. 

  

	 	•	 	 Cash and other assets easily convertible into cash are passive assets, even when used as working capital. 

 

	 	•	 	 Stock and securities (including tax-exempt securities) are passive assets, unless held by a dealer as inventory. 

Average value: For purposes of this test, “average fair market value” equals the average quarterly fair market value of the
assets for the relevant taxable year. 
 Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by
value of another corporation, the Company must take into account its proportionate share of the passive assets of such other corporation. 
  

	(4)	PLEASE CHECK HERE IF (A) MORE THAN 50% OF
THE COMPANY’S STOCK (BY VOTING POWER OR BY VALUE) IS OWNED
BY FIVE OR FEWER U.S. PERSONS OR ENTITIES AND (B) THE AVERAGE
AGGREGATE ADJUSTED TAX BASES (AS DETERMINED UNDER U.S. TAX PRINCIPLES) DURING THE
TAXABLE YEAR OF THE PASSIVE ASSETS HELD BY THE COMPANY EQUALS 50% OR
MORE OF THE AVERAGE AGGREGATE ADJUSTED TAX BASES OF ALL OF THE
COMPANY’S ASSETS. 

 Average value: For purposes of this test,
“average aggregate adjusted tax bases” equals the average quarterly aggregate adjusted tax bases of the assets for the relevant taxable year. 
 Look-through rule: if the Company owns, directly or indirectly, 25% of the stock by value of another corporation, the Company must take into account its proportionate share of the passive assets of such
other corporation 
  

	(5)	[PREFERRED SHAREHOLDER] HAS THE FOLLOWING PRO-RATA
SHARE OF THE ORDINARY EARNINGS AND NET CAPITAL GAIN OF THE COMPANY
AS DETERMINED UNDER U.S. INCOME TAX PRINCIPLES FOR THE TAXABLE YEAR OF
THE COMPANY: 

 Ordinary Earnings:
                     (as determined under U.S. income tax principles) 
 Net Capital Gain:                      (as determined under U.S income tax principles)

 Pro Rata Share: For purposes of the foregoing, the shareholder’s pro rata share equals the amount that would have been
distributed with respect to the shareholder’s stock if, on each day during the taxable year of the Company, the Company had distributed to each shareholder its pro rata share of that day’s ratable share (determined by allocating to each
day of the year, an equal amount of the Company’s aggregate ordinary earnings and aggregate net capital gain for such year) of the Company’s ordinary earnings and net capital gain for such year. Determination of a shareholder’s pro
rata share will require reference to the Company’s charter, certificate of incorporation, articles of association or other comparable governing document. 

  
 64 

	(6)	The amount of cash and fair market value of other property distributed or deemed distributed by Company to [Preferred Shareholder] during the taxable year specified in
paragraph 1. is as follows: 

 Cash:
                     

Fair Market Value of Property:
                     
  

	(7)	Company will permit [Preferred Shareholder] to inspect and copy Company’s permanent books of account, records, and such other documents as may be maintained by
Company that are necessary to establish that PFIC ordinary earnings and net capital gain, as provided in Section 1293(e) of the U.S. Internal Revenue Code of 1986, as amended (or any successor provision thereto), are computed in accordance with
U.S. income tax principles.
