     4.   March 17, 2005 German  Press  Release - SGL Carbon to Increase  Prices
          for Carbon Fibers and Carbon Fiber Products




SGL Carbon increases Graphite Electrode prices

Wiesbaden,  January  14,  2005.  SGL Carbon  announces  today new prices for its
Graphite  Electrodes  effective  January 15, 2005 for all new businesses in (the
last price  announcement  of September  28, 2004 was binding  until  January 14,
2005):

Americas, Asia (excluding China*), Near Middle East and Africa:
        o  For regular-sized Graphite Electrodes:      1,66 US$/lb  (3650 U$/mt)
        o  For extra-sized Graphite Electrodes:        1,82 US$/lb  (4000 U$/mt)

Europe:
        o  For regular-sized Graphite Electrodes:      2730 (euro)/mt
        o  For extra-sized Graphite Electrodes:        3000 (euro)/mt

           Regular sized is defined as:     Diameter 12" (300mm) - 24" (600 mm)
           Extra sized is defined as:       Diameter 26" (650mm) - 30" (750 mm)

These prices will be applicable for all orders  received by June 3, 2005 and for
shipments effected prior to December 31, 2005.

The steel industry continues to operate at record levels globally resulting in a
continuing strong demand for high performing graphite  electrodes.  For the year
2005 SGL Carbon is almost fully booked with firm orders for graphite electrodes.
Consequently  the strong demand for graphite  electrodes  has generated a strong
demand for needle coke,  the primary raw material  for the  manufacture  of high
power graphite electrodes.  SGL has contracted  sufficient  quantities of needle
coke to meet the demand in 2005, including contingencies.

The  combination  of  continuing  pressure  on  our  manufacturing   facilities,
increased  prices of all raw  materials  and energy as well as higher  operating
expenses,  significant  higher  logistic  costs and the  impact of the  volatile
exchange  rates has  resulted in higher cost for our graphite  electrodes  which
makes further adjustments of our electrodes prices unavoidable.

*Pricing in China is the sole  responsibility  of the joint venture  between SGL
Carbon and Tokai in Shanghai (STS).

SGL Carbon and Mitsubishi Rayon agree on co-operation in Carbon fiber

Wiesbaden,  January 31, 2005.  SGL Carbon and  Mitsubishi  Rayon Corp.  of Tokyo
Japan (MRC) have  agreed on a strategic  co-operation  in carbon  fiber.  Having
recently  signed  respective  long-term  contracts,  SGL  will  receive  certain
technologies, special raw material and support from MRC. This will assist SGL to
produce a highly improved Carbon fiber in its plant in Inverness/Scotland.

The unique  performance  potential  of this new carbon  fiber has  already  been
proven in pilot  plants at SGL and MRC. It  combines  the  performance  and high
quality  of  regular  small-tow  carbon  fiber  with  the  efficient  production
capacities SGL has developed in its plant in Inverness. The new fiber will allow
SGL to develop and capitalize on new  applications  including  automotive,  wind
energy,  infrastructure  and  concrete  reinforcement  applications,  from  2006
onwards.

As part of the strategic  alliance in technical and raw material  areas MRC will
receive in return up to 750 tons of this new carbon  fiber from SGL under a long
term supply agreement starting from Q1 2006 following further own investments of
MRC. Both sides are viewing the  co-operation  on the development and production
of the new  carbon  fiber as a first step  together,  and have  expectations  to
further  build the  partnership.  The  strategic  co-operation  strengthens  SGL
Carbon's global  competitive  position in the carbon fiber market especially for
high  quality  products,  in terms of  technology,  raw  material  and  capacity
utilization.  Furthermore SGL Technologies' own downstream  business in prepreg-
composite- and carbon/ceramic-materials (e.g. brake discs) will benefit from the
new carbon fiber quality.

SGL's Carbon Fibre  business  includes a 100 % owned modern  facility of approx.
5000 tons capacity for oxidized and carbon fiber in Inverness,  Scotland as well
as a 50 %  participation  in Carbon Fiber  Technology LLC (CFT), a Joint venture
with  Aldila Inc.  San  Diego/California  with  further  1000 tons carbon  fiber
capacity in Evanston,  Wyoming,  USA. Both plants were built up in recent years,
and include state of the art large  capacity  production  lines.  In total SGL's
Carbon Fiber  business  has a turnover of approx.  (euro)m 35 million at present
and is expected to grow in double digits over the next several years.

The  agreement  and  cooperation  with  Mitsubishi,  one of the world's  leading
manufacturers  of carbon fibers and  especially of the carbon fiber raw material
Polyacrylonitrile  (PAN),  represents  a major  stretegic  step  change in SGL's
worldwide carbon fiber business.

SGL Carbon: Fiscal year 2004

o  Portfolio streamlining due to sale of Surface Protection business

o  EBIT before restructuring expenses up 51%

o  Net debt substantially lower 

o  Considerable increase in earnings projected for 2005

Wiesbaden,  March 10, 2005. SGL Carbon's annual financial  statement for 2004 is
characterized  by the sale of its Surface  Protection  business,  a  substantial
increase in EBIT, and a significant improvement in free cash flow and net debt.

Increase in profits from continuing operations
On January 6, 2005,  the sale of the Surface  Protection  business of the former
Corrosion Protection (CP) business was completed.  As a result of this portfolio
streamlining, SGL Carbon was able to dispose heavily loss-making operations (net
loss in 2004:  (euro) 21  million,  including  a loss on EBIT level of (euro) 17
million).  On Group level,  the sale resulted in a non-cash  book  write-down of
(euro) 65 million on the carrying value. Both effects are recorded in the annual
financial  statements under "discontinued  operations".  As previously reported,
SGL Carbon is retaining the profitable Process  Technology (PT) business,  which
generated  sales of (euro) 47 million in 2004. The sale as well as  improvements
across  all  businesses  resulted  in  a  substantial  improvement  of  the  key
performance   indicators  for   "continuing   operations".   Thus,  EBIT  before
restructuring expenses rose by 51% year on year from (euro) 56 million to (euro)
85 million  and after  restructuring  expenses  by 39% from (euro) 47 million to
(euro) 65 million.

Return to profitability
In the year under review, net financing costs improved from (euro) 75 million in
the previous year to (euro) 60 million due to the decrease in refinancing  costs
from  (euro)  16  million  in 2003 to  (euro) 4  million  in 2004.  At (euro) 50
million, interest expense on loans and pensions remained almost unchanged (2003:
(euro) 49 million),  although net interest  expense on loans rose from (euro) 23
million to (euro) 30 million.

SGL Carbon's  "continuing  operations"  reported a profit before tax of (euro) 5
million  (2003:  loss of (euro) 48  million).  The after tax profit was (euro) 4
million  (previous year: loss of (euro) 29 million).  "Discontinued  operations"
generated  a net loss of (euro) 86  million in 2004,  comprising  largely a book
write-down  of (euro) 65 million on the carrying  value and the accrued net loss
of (euro) 21 million for the year. In total,  consolidated net loss increased to
(euro)  82  million  in 2004,  from  (euro) 50  million  in the  previous  year,
equivalent to a loss per share of (euro) 1.57 (2003: (euro) 2.27).

Carbon and Graphite (CG): Substantial improvement in earnings
At (euro) 555 million, CG sales remained nearly unchanged over the previous year
(2003:  (euro) 558  million),  but rose by 5% without  currency  effects.  Sales
volumes of Graphite  Electrodes climbed by 3% to a record level of 209,000 tons.
Price  increases  of an  average  of 1% in the euro  zone and 14% in the  dollar
region were  accepted  in the  market,  although  the  effects  were  negatively
influenced by the exchange-rate  parities.  In spite of the weak US dollar, EBIT
before restructuring  expenses increased by over 42% to (euro) 98 million (2003:
(euro) 69 million).  The ongoing  cost-cutting  programs  yielded net savings of
(euro) 17 million compared to 2003.

Graphite Specialties (GS): Integration of Process Technology (PT) business
GS sales including the integrated PT business (sales in 2004: (euro) 47 million;
2003:  (euro) 56  million)  rose by 3% to (euro) 236 million  (2003:  (euro) 230
million).  The positive volume and price effects of 5% were negatively  impacted
by currency (2%). EBIT before  restructuring  expenses including PT climbed from
(euro) 16 million to (euro) 17 million.  On a comparable  basis,  EBIT more than
doubled from (euro) 7 million to (euro) 17 million when  eliminating  a large PT
project which had contributed an additional (euro) 6 million in 2003.  Moreover,
one time gain of (euro) 3 million  bettered  the GS business in 2003 as a result
of the sale of  EC-business.  Net  savings  contributed  (euro) 6 million in the
year.

                                       2


SGL Technologies (SGL T): Significant increase in demand
Spurred by improved business  conditions,  SGL T sales increased by 6% to (euro)
133 million in 2004,  rising by as much as 13% adjusted by currency  translation
impacts. Sales of Carbon Fiber and  Carbon-Ceramic-Brake  Disc were particularly
encouraging.  EBIT in this  segment  was  burdened  by  start-up  costs  for new
aerospace and defense  projects as well as additional  research and  development
expenses of (euro) 5 million including the projected  development of large-scale
serial  production for our  Carbon-Ceramic-Brake  Discs.  Loss at the EBIT level
before restructuring  expenses came to (euro) 9 million,  down from the previous
year's   loss   of   (euro)   12   million.   Excluding   the   losses   of  the
Carbon-Ceramic-Brake  Disc business,  SGL T came close to break even at the EBIT
level in 2004.

Balance sheet structure improved - net debt down
The balance sheet improved  substantially over 2003 primarily as a result of the
successful  refinancing  and the sale of Surface  Protection  business.  Whereas
total assets increased by (euro) 68 million to (euro) 1,315 million, equity rose
by (euro) 165 million to (euro) 282 million,  resulting in an improvement in the
equity ratio from 9% to 21%. On a pro-forma  basis,  i.e.  excluding  the assets
held for "discontinued operations" of (euro) 64 million (date of sale January 6,
2005) as well as the special escrow accounts to cover the remaining repayment of
the  convertible  bond  maturing in 2005 ((euro) 51 million)  and for  antitrust
fines ((euro) 77 million), the equity ratio stands at 25%.

In the year under  review,  net debt was reduced by (euro) 127 million to (euro)
321 million (December 31, 2004) mainly due to the capital increase  concluded on
February 9, 2004 which generated net proceeds of (euro) 244 million. Of these, a
sum of  (euro)  128  million  was  still  held at the end of the year in the two
escrow  accounts for the repayment of the  convertible  bond and for  anti-trust
payments.  Even after the capital  increase,  net debt was further  reduced from
(euro) 365 million (March 31, 2004) to (euro) 321 million.

                                       3



Substantial improvement in earnings expected for 2005
SGL Carbon  expects to achieve an increase  in sales of approx.  5% as well as a
disproportionately  high  EBIT  growth.  This  positive  performance  should  be
supported by all  businesses.  CG expects to achieve higher  earnings  thanks to
continued  strong  demand  in  Graphite  Electrodes  leading  to  full  capacity
utilization,  price  increases  already  implemented  and  further  cost-cutting
activities.  GS will also be able to report a higher  profit on the  strength of
volume and price increases as well as ongoing  cost-reductions.  Demand in SGL T
will   show   some   turnover    growth   whilst    earnings    should   improve
overproportinately.

With  most of the  restructuring  efforts  completed,  the  Company  will  cease
reporting  ongoing  restructuring  costs  in the  future.  Based  on  continuing
positive cash flow, SGL Carbon will reduce debt further.  The Company expects an
EBIT of more than (euro) 15 million for the first quarter of 2005.

SGL Carbon to increase prices for carbon fibers
and carbon fiber products

Wiesbaden, March 17, 2005. SGL Carbon's business unit SGL Technologies announces
price  increases  across its carbon fiber products range with immediate  effect.
The double  digit  percentage  increases  vary from  product to product and will
affect  the  Company's  carbon  fibers as well as  fabrics,  prepregs  and other
fiber-reinforced matrix products.

Jan Verdenhalven,  Managing Director of SGL Technologies commented: "These price
increases  are based on raw material  cost  increases as well as on  continually
tightening demand and supply situation in the carbon fiber markets."
