                                                                      On June 26, 2006, OAO Tatneft issued the following press release:
June 26, 2006

For immediate release

OAO Tatneft announces its intention to delist from the New York Stock Exchange and to terminate its registration with the SEC

OAO Tatneft  (NYSE:  TNT;  LSE:  ATAD) (the  "Company")  announced  today that it plans to delist  voluntarily  from the New York Stock
Exchange  (the "NYSE") so as to  concentrate  trading in its equity  securities  outside of the Russian  Federation on the London Stock
Exchange (the "LSE").  In addition,  when  circumstances  permit,  the Company intends to apply for termination of the  registration of
its ordinary shares with the U.S. Securities and Exchange Commission (the "SEC").

The  decision  to  delist  from the NYSE and to  terminate  the  registration  with the SEC has been  taken  following  a review of the
appropriateness  of  maintaining  multiple  international  listings.  The Company is the only major Russian issuer to have a listing in
both London and New York.  Given the increase in recent years in costs  associated with the  registration  of the Company's  securities
with the SEC, a decision was made to  concentrate  international  trading of the Company's  equity  securities  in London.  The Company
believes that direct cost savings,  resulting from the planned  de-listing and deregistration in the United States, can be realized for
shareholders and that the focus on a single international trading market for the Company's equity securities may increase liquidity.

The Company  currently  expects to file its application for delisting from the NYSE in mid-August  2006.  Following  delisting from the
NYSE and pending the filing of the  Company's  application  for  deregistration  from the SEC, the Company  will remain  subject to the
regulations  of the  SEC.  To  facilitate  termination  of the  registration  of its  ordinary  shares  with the SEC,  the  Company  is
considering  amendments to the deposit  agreement  relating to its ADR facility (the "Deposit  Agreement")  that would prevent  persons
resident in the United  States  (other than certain  "qualified  institutional  buyers"  identified  by the Company  acting in its sole
discretion) from  participating in the facility.  The Company  currently  expects that The Bank of New York, the depositary for the ADR
facility  (the  "Depositary")  and the Company  will sign these  amendments,  and that the  Depositary  will give formal  notice of the
amendments  to  registered  owners of ADRs,  on or about July 10,  2006.  The  Company  intends to  reserve  the right to refrain  from
implementing  the proposed  amendments to the Deposit  Agreement in the event that the SEC adopts new rules relating to  deregistration
in a form that would permit the Company to deregister without implementing those amendments.

The Company's  representatives  will discuss the planned delisting and deregistration  and U.S. GAAP financial  highlights for 2004 and
the first half of 2005 on a conference  call at 9 a.m.,  Eastern  Daylight  Time,  2 p.m.  British  Summer Time, 5 p.m.  Moscow time on
Tuesday, June 27, 2006.   To participate in this conference call, dial one of the following numbers using participant code C915967:

Further information on the Company's current  expectations  regarding timing of the various steps associated with the planned delisting
and the  proposed  amendments  to the  Deposit  Agreement  can be found in Appendix  A.  Further  information  regarding  the  proposed
amendments to the Deposit Agreement and related matters can be found in Appendix B.

                                                              Appendix B
                                               Proposed Amendments to Deposit Agreement

The proposed amendments to the Deposit Agreement would include principally the following:

-        Requiring  that,  on or before a date  designated  by the Company and the  Depositary  with at least 30 days' prior  notice to
         owners of ADRs (the  "Certification  Date"),  beneficial owners of the ADRs must certify either (i) that they are not resident
         in the United States or (ii) that they are  "qualified  institutional  buyers" or "QIBs" and that they request to be permitted
         to continue to hold GDRs following the Certification Date;[1]

-        Redesignating  the  ADRs  as  "Global  Depositary  Receipts"  ("GDRs")  with  effect  as  of a few  business  days  after  the
         Certification Date;

-        Introducing a provision that the ordinary  shares  underlying all GDRs except those  beneficially  owned by persons who, on or
         before the  Certification  Date,  (i) have  certified that they are not "resident in the United States" or (ii) have certified
         that they are QIBs and have been  approved by the Company,  will be sold by Depositary  outside the United States  pursuant to
         Regulation S under the U.S.  Securities Act of 1933, as amended (the  "Securities  Act"),  and that,  upon completion of those
         sales, the proceeds of those sales will be transferred to the beneficial holders of such GDRs;

-        Introducing  a provision  that  deposits  into the  restructured  GDR facility  will be accepted only from persons who are not
         resident in the United States; and

-        Introducing  a provision  that  transfers  of the GDRs may not be made to  U.S.-resident  persons  other than to QIBs who take
         delivery  pursuant to a new deposit  facility  that the Company  intends to  establish  to permit (i)  purchase and holding of
         depositary  receipts  representing  the Company's  ordinary shares by  U.S.-resident  QIBs and (ii) trading in such depositary
         receipts among U.S.-resident QIBs (the "Rule 144A Deposit Facility").

The amendments to the Deposit  Agreement  would provide that the Company may instruct the  Depositary to refrain from selling  ordinary
shares  underlying GDRs beneficially  owned by certain QIBs identified by the Company acting in its sole discretion,  even if such QIBs
are resident in the United States.  The Company  currently  expects to exercise this  discretion to permit certain  U.S.-resident  QIBs
with the largest holdings of ADRs prior to the  Certification  Date to continue to hold GDRs after the  Certification  Date, so long as
this does not in the Company's view  jeopardize the Company's  ability to terminate the  registration  of its ordinary  shares with the
SEC under  applicable  rules.  The  amendments  to the Deposit  Agreement  also would  provide that the Company may, from time to time,
serve a mandatory  notice on any one or more such QIBs  (identified by the Company,  acting in its sole  discretion)  requiring them to
transfer  their GDRs to a non-U.S.  resident  person or,  upon  expiration  of a  reasonable  period,  to require the  ordinary  shares
underlying the GDRs  beneficially  owned by such QIBs to be sold by the Depositary  outside the United States  pursuant to Regulation S
under the  Securities  Act, and that,  upon  completion of those sales,  the proceeds of those sales will be  transferred to such QIBs.
The new deposit  agreement  that the Company and the  Depositary  propose to enter to establish  the Rule 144A Deposit  Facility  would
contain a similar provision.

The GDRs would remain listed on the LSE. The  depositary  receipts  issued from the Rule 144A Deposit  Facility  would not be listed on
the LSE or on any other securities exchange.

The Company is aware that the SEC has proposed new rules  governing  termination  of  registration  of securities  under the Securities
Exchange Act of 1934,  as amended.  Such rules,  when adopted by the SEC, may permit the Company to terminate the  registration  of its
ordinary  shares  with the SEC  without  the need to amend its  Deposit  Agreement  as  described  above.  If and when  such  rules are
adopted,  the Company  intends to reassess  the Deposit  Agreement  (and the new deposit  agreement  relating to the Rule 144A  Deposit
Facility) to determine whether  restrictions on participation in the related  depositary  receipt facilities by persons resident in the
United States could be relaxed without  jeopardizing  the Company's  ability to terminate the  registration of its ordinary shares with
the SEC.

________________________________________________________________________________

[1]      Under the  amendments  to the Deposit  Agreement,  a  beneficial  owner's  certification  that he, she or it either (i) is not
         "resident  in the United  States" or (ii) is a QIB and  requests  permission  to continue  to hold GDRs will not be  effective
         unless the beneficial owner,  together with the certification,  deposits its GDR with the Depositary or transfers the relevant
         GDRs to a blocked account with The Depository Trust Company,  in either case until after the  Certification  Date. The purpose
         of this requirement is to prevent  beneficial owners that have either (i) certified  non-U.S.  residence or (ii) certified QIB
         status and  requested  permission  to  continue to hold GDRs from  transferring  their ADRs to a person who is resident in the
         United States prior to the Certification Date.
