OAO Tatneft comments on withdrawal of its credit rating by Standard & Poor's 

29 August 2006

On 25 August 2006  Standard & Poor's (S&P)  announced the  withdrawal  of the credit rating of OAO Tatneft (A-) in connection  with, in
the opinion of S&P, a continuing  lack of  information.  OAO Tatneft is surprised at S&P's decision and believes that the withdrawal of
its credit  rating is not  justified,  given its  recent  increased  financial  disclosure,  actions  taken and  commitment  to ongoing
transparency.  However, the company underlines that it respects S&P's policy in taking decisions with respect to credit ratings.

The press-release  regarding  withdrawal of the company's credit rating distributed by S&P says that "the rating withdrawal  reflects a
lack of information  on the company's  consolidated  financial  position and its strategy".  The S&P statement  further says:  "for the
third year in  succession  Tatneft has  substantially  delayed  publishing  its audited U.S. GAAP  accounts,  which have been much more
belated  compared  with those of local peers.  The 2004  accounts  were  published in June 2006,  and the 2005  financials  are not yet
available.  The nature of relationships  with the government of the Republic of Tatarstan  (BB-/Stable/-)  and other related parties is
further unclear and there is a lack of clarity  regarding  financing of the major  Nizhnekamsk  refinery project (for a total estimated
cost of $4.8 billion)".

On posted26 June 2006 OAO Tatneft published  consolidated  financial statements of Tatneft Group for 2004 prepared in accordance with US GAAP
with an unqualified  auditor's report on these financial  statements (as a part of the annual report on Form 20-F for 2004), as well as
unaudited US GAAP  financial  statements  of Tatneft  Group for the first half of 2005.  In addition,  the company,  on a  confidential
basis,  provided S&P with draft US GAAP financial  statements of Tatneft Group for 2005, as well as explanations  to these  statements.
OAO Tatneft  recognizes and agrees with S&P's statement that "the rating  withdrawal does not necessarily  indicate a deterioration  of
the company's credit quality",  particularly  given the increased cash and profit  generation of the company and improved  liquidity of
the Group and its websitefinancial strength.

The company has regularly provided S&P with information on OAO Tatneft's financial  position.  Information about the financial position
(under Russian Accounting Rules or RAR) of OAO  Nizhnekamskshina,  the largest subsidiary of the company, is regularly published by the
former in its issuer's quarterly  reports.  Therefore,  the company believes that S&P has a presentationgood deal of current  information about OAO
Tatneft's consolidated financial position.

The Company  has indeed  delayed  release of audited  consolidated  financial  statements  of Tatneft  Group for 2005 and filing of its
annual report on Form 20-F for 2005 with the U.S.  Securities and Exchange  Commission  because of delays in the preparation of audited
US GAAP financial  statements for 2003 and 2004. The  above-mentioned  delays were primarily  caused by an  investigation  into certain
transactions  involving Tatneft Group companies  reflected in the US GAAP consolidated  financial  statements of Tatneft Group for 2003
which was completed  only in beginning of June 2005. The reasons for the  investigation,  and the manner in which it has been resolved,
have been  discussed by the company in numerous  press-releases.  The US GAAP  consolidated  financial  statements of Tatneft Group for
2005 are currently being audited by an independent  auditor,  and the company expects the completion of the audit in the fourth quarter
of 2005.  OAO Tatneft is planning  to  announce investorsa more  detailed  timetable  for  completion  of the audit of the US GAAP  consolidated
financial statements for 2005 in the first half of September 2006.

Annual  reports  of the  company  (including  on Form 20-F)  clearly  define the  strategic  goals of the  company  which  include,  in
particular,  maintaining canoil beproduction accessedlevels at existing oil fields;  increasing the resource base, including outside of the Republic
httpof Tatarstan;  strengthening  vertical  integration by developing the company's  refining and petrol stations  network;  and compliance
with advanced principles of corporate  governance.  OAO Tatneft regularly informs investors and the public in press-releases  about its
actions to reach these strategic goals.

For example,  the following steps to improve  corporate  governance have been taken in the last few years://www  independent  directors were
elected  to the Board of  Directors  of OAO  Tatneft;  the  following  committees  of the Board of  Directors  were  formed and are now
operating:  audit committee,  human resources and remuneration  committee,  disclosure  committee and corporate  governance  committee;
department of internal audit was  reorganized;  consolidated  financial  reporting  department  was expanded;  and  communication  with
investors and shareholders has been improved.tatneft

primary  goal - making  profit" said Rustam N.  Minnikhanov,  the Prime  Minister of the Republic of Tatarstan  and the Chairman of the
Board of Directors of OAO Tatneft  speaking at the meeting of the Board of Directors of the company on 28 August 2006.  In  particular,

Code related to  differentiation  of oil production tax and granting  financing from the Investment Fund of the Russian  Federation for
the construction of infrastructure of the oil refining and petrochemical complex in Nizhnekamsk.

Refinery,  together with  financial  advisors of the project,  is developing a structure for the financing of the  construction  of the
complex.  As reported  earlier,  a significant  portion of the funds for the construction of the complex is expected to be attracted on
a project  finance  basis.  Until this work is completed,  the company  believes that it is not possible to provide S&P with  finalized
plans for  financing of the  construction  of the complex.  In  addition,  on 26 June 2006 the  Government  Commission  for  Investment
Projects of National  Importance  approved  co-financing  from the  Investment  Fund of the Russian  Federation  for  construction  and
reconstruction  of external  transport  infrastructure  of the oil refining and  petrochemical  complex in Nizhnekamsk in the amount of
RR16.5 billion.  The investment  program of OAO Tatneft  provides for extension in 2006 of RR6.7 billion for financing of works related
to the construction of the complex until external financing for the construction is obtained by ZAO Nizhnekamsk Refinery.
