Subject	Yandex N.V. - Legal Opinion on Prospectus Supplement on Form 6-K

Dear Sirs,

We, Van Doorne N.V., have acted as special legal advisers to Yandex N.V. (the “Company”) in connection with the offering (the “Offering”) of 9,340,101 Class A Ordinary Shares with a nominal value of EUR 0.01 each in the capital of the Company (the “Offer Shares”), including up to 1,218,274 additional Class A Ordinary Shares with a nominal value of EUR 0.01 each in the capital of the Company, in each case as described in the Prospectus Supplement filed by you with the U.S. Securities and Exchange Commission (the “Prospectus Supplement”).

This legal opinion is furnished to you in order to be filed in connection with the Offering with the U.S. Securities and Exchange Commission. Unless otherwise defined in this legal opinion (including the Schedule) or unless the context otherwise requires, words and expressions defined in the Prospectus Supplement will have the same meanings when used in this legal opinion.

For the purpose of this legal opinion we have examined and relied on the documents listed in the Schedule (the “Documents”) and such other documents as we in our absolute discretion have deemed relevant.

In connection with our examination and in giving the opinions expressed below we have assumed:

a) the genuineness of the signatures on the Documents, the authenticity and completeness of the Documents submitted to us as originals, the conformity to the original documents of any Documents submitted to us as drafts, (electronic or hard) copies or translations and the authenticity and completeness of the original documents;

b) that (1) no resolution for the dissolution (ontbinding) of the Company has been taken, no application has been made for the bankruptcy (faillissement) or the (provisional) suspension of payments (surseance van betaling) of the Company, (2) the Company has not been dissolved and has not been declared bankrupt or granted a (provisional) suspension of payments in the Netherlands, (3) no foreign insolvency proceedings have commenced in respect of the Company and (4) no order for the administration of assets of the Company has been made;

c) that the factual confirmations contained in the Corporate Resolutions accurately and completely reflect the matters purported to be evidenced thereby;

d) that the issue price for the Offer Shares shall have been paid in full in cash and shall have been received by the Company;

e) that no acquiror of the Offer Shares is subject to, controlled by or otherwise connected with a person, organisation or country which is subject to United Nations, European Union or Dutch sanctions implemented or effective in The Netherlands under or pursuant to the Sanction Act 1977 (Sanctiewet 1977), the Economic Offences Act (Wet economische delicten), the General Customs Act (Algemene Douanewet) or Regulations of the European Union; and

f) that any foreign law which may apply with respect to the issue of the offer Shares does not affect this legal opinion.

This legal opinion is given only with respect to Dutch law in force as at the date hereof and as applied and generally interpreted on the basis of case-law published on the date hereof. We do not assume any obligation to advise you (or any other person entitled to rely on this legal opinion) of subsequent changes in Dutch law or in the interpretation thereof.

Based on and subject to the foregoing and subject to the qualifications set out below and matters of fact, documents or events not disclosed to us, we express the following opinions:

1 The Company is duly incorporated as a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) and is validly existing under Dutch law as a limited liability company (naamloze vennootschap).

2 The Offer Shares have been validly issued and fully-paid and are non-assessable.

The opinions expressed above are subject to the following qualifications:

(A) Our opinions expressed herein are subject to and limited by applicable Dutch or foreign bankruptcy, suspension of payment, insolvency, reorganisation and other laws relating to or affecting the rights of creditors or secured creditors generally.

(B) The term “non-assessable” as used in this legal opinion means that the holder of a share will not by reason of merely being such holder, be subject to assessment of calls by the Company or its creditors for further payment on such share.

(C) Our opinions expressed herein may be affected by (i) the rules of good faith (redelijkheid en billijkheid), force majeure (niet-toerekenbare tekortkoming) and unforeseen circumstances (onvoorziene omstandigheden), (ii) the general defences available to debtors under Dutch law which include rights to suspend performance (opschortingsrechten), rights of set-off (verrekening), mistake (dwaling), duress (bedreiging), fraude (bedrog), undue influence (misbruik van omstandigheden) and fraudulent preference (pauliana) and (iii) the rules of decency (goede zeden) and public order (openbare orde).

This legal opinion is given subject to, and may only be relied upon on, the express condition that (i) Van Doorne N.V. is the exclusive party issuing this legal opinion, (ii) in respect of Dutch legal concepts, which are expressed in this legal opinion in English terms, the original Dutch terms shall prevail and (iii) this legal opinion shall be governed by, and construed in accordance with, Dutch law.

This legal opinion is strictly limited to the matters stated herein and may not be read by implication as extending to matters not specifically referred to and may only be relied upon in connection with the Offering. We hereby consent to the filing of this legal opinion in connection with the Offering with the U.S. Securities and Exchange Commission and the reference to Van Doorne N.V. in the Prospectus Supplement under the caption “Legal Matters”. In giving such consent, we do not admit that we come within the category of persons whose consent is required under Section 7 of the U.S. Securities Act of 1933 or the rules and regulations promulgated thereunder.

Yours faithfully,
/s/ Van Doorne N.V.
