chairman’s statement
the results for the year have met 
market expectations despite a business
environment that continues to remain
tough turnover and pretax profits for 
the year which include the six month
contribution from our acquisition were
£83m and £15m respectively 2003
£63m and £22m basic earnings per
share were 302p 2003 454p
the group’s major achievement this year
has been the successful acquisition and
integration of seravac biotech proprietary
limited and its subsidiary “seravac”
seravac was established in cape town in
1955 and is a significant supplier of
naturally derived enzymes to markets
including the diagnostic pharmaceutical
biotechnology and research industries 
this acquisition has consolidated the
group’s existing position as one of the
world’s leading producers and suppliers of
diagnostic enzymes it has also extended 
the range of products with therapeutic
potential jacobus de kock one of the
former vendors of seravac is now executive
chairman of seravac and we are delighted
to welcome him onto the theratase board
as a nonexecutive director
the acquisition was funded by way of a
placing and open offer and through a new
senior debt facility at the same time we
were able to redeem the company’s
outstanding preference shares through
this early redemption we have been able 
to maximise shareholder value simplify 
the company’s capital structure and
manage more efficiently the maturity of 
our funding commitments
the group has also made progress with its
therapeutic projects in february 2004 we
announced a new joint venture investment
in a swedish biopharmaceutical company
applet with pharmalink a swedish
speciality pharmaceutical company
theratase and pharmalink will each invest
approximately £05m in the joint venture
contingent upon achieving development
milestones at 30 september 2004
£01m had already been invested by the
group in the project applet will initially
develop therapeutics using the enzyme
hyaluronidase for use as an antioedema
and antiinflammatory agent in the
prevention of transplant rejection the
group’s uk based subsidiary biozyme
laboratories will ultimately supply
hyaluronidase to the venture on the 
basis that development is successful 
in january 2004 we agreed to make 
a further investment in the form of a
€200000 convertible loan in ampharma
holdings bv “ ampharma” the dutch 
joint venture founded in 2000 to develop
therapeutics and diagnostic treatments for
sepsis and microbial infections theratase
made the investment on 2 december 2004
following the successful achievement of the
required technical milestone by ampharma
this investment which is part of a larger
fund raising initiative by ampharma to raise
a minimum of €175m is to fund extended
phase iia clinical trials using alkaline
phosphatase supplied by biozyme in sepsis
patients the commencement of these trials
was temporarily delayed by an ethical review
relating to patient informed consent which
have now been resolved it is now
anticipated that trial results will be
available by the third quarter of 2005 
an important technical milestone 
was achieved in may when ista
pharmaceuticals announced that it had
received us fda approval for the use of
vitrase
®
as a spreading agent biozyme
produces the active pharmaceutical
ingredient hyaluronidase for vitrase
®
 
this approval enables ista to sell vitrase
®
to ophthalmologists needing to facilitate
spreading of other drugs in the eye 
this represents an important event for
biozyme’s manufacturing facility which was
audited successfully by the fda in 2003
on behalf of the board i would like to
welcome our new employees in south
africa to the group and to thank them as
well as all of our uk and usa employees
for their efforts which are so important to
the continued success of the group 2004
has been a year of great change for the
group with new opportunities introduced
and a broadening of our offerings i look
forward to the challenges ahead in
improving profitability and seeking out
further appropriate opportunities
philip percival
chairman
18 january 2005
“the last 12 months have been a time of considerable
development and change for the group we have
succeeded in making major advances in progressing
the group’s strategy which is to build a specialist
pharmadiagnostics company through organic growth
appropriate synergistic acquisitions and by investing 
in research and development through therapeutic joint
ventures the group’s operations have continued to be
profitable and cash generative”

biozyme
diagnostic
biozyme’s most important products
continue to be glucose oxidase and
alkaline phosphatase over many 
years biozyme has established solid
relationships with some of the major
players in the diagnostics market
including lifescan europe a subsidiary 
of johnson  johnson which is one of
the main customers for glucose oxidase
which is incorporated into home blood
glucose testing kits this market is
growing at a rate of over 10 per 
annum due to the increasing incidence 
of diabetes worldwide alkaline
phosphatase which is manufactured 
from bovine intestine is a key enzyme
used extensively in immunodiagnostic
testing for the diagnosis of disease and
monitoring of physiological change it is
also used in pathology and organ function
tests during the last year considerable
efforts alongside defra department 
of the environment farming and rural
affairs have been made to ensure that
our manufacture and supply of alkaline
phosphatase continues to meet the 
latest eu regulations other enzymes 
for which biozyme holds a strong market
reputation include hyaluronidase
ribonuclease and urease
therapeutic
the core business and the sales it
generates through the diagnostics 
market are critically important for 
the group’s financial performance
additionally biozyme and seravac 
the recently acquired south african
business together represent a platform
for theratase to grow into new markets 
biozyme has through its excellent
production skills and product specification
profiles enabled theratase to access
exciting pharmaceutical product
development programmes which
incorporate enzymes produced by the
company as active pharmaceutical
intermediates apis in this respect the
recent rating of one of the manufacturing
units within biozyme by the us fda as
compliant with good manufacturing
practice gmp enables the inhouse
expertise to be employed to maximum
advantage in the new development
projects in which the company is
engaged gmp compliance is necessary
for the regulatory approval of therapeutic
products andor their components
achieving gmp compliance underlines 
our strategy of achieving maximum value
for shareholders by exploiting biozyme’s
core skills base and developing this along
ultimately more lucrative lines such as 
the production of substantially higher
margin enzymes as apis
the company is engaged in the following
api programmes exploiting the enzymes 
it produces for therapeutic applications
organ transplant rejection 
theratase recently announced the
formation of a new joint venture applet
mbj ab “applet” established with the
swedish speciality pharmaceutical
company pharmalink each company
plans to invest £05m in return for a
chief executive’s review
“the acquisition of seravac has broadened the group’s
turnover product and manufacturing bases and a 
new therapeutic programme has been commenced 
the group will be concentrating its efforts over the next
year on improving profitability at seravac as well as
continuing to seek out appropriate therapeutic
opportunities to fuel growth”

chief executive’s review continued
475 stake in the jv theratase will be
making its payments in four tranches over
a 14 month period which commenced 
in february 2004 on the achievement 
of developmentrelated milestones 
at year end the group had invested
£01m applet is exploring the use of
hyaluronidase for its potential to reduce
organ transplant rejection currently there
is no effective strategy for controlling
rejection within the first 24 hours of
organs transplanted into patients applet
intends to take hyaluronidase through 
the preclinical stage and into phase i 
and ii clinical trials intellectual property
generated through the work will be owned
by applet it is believed that hyaluronidase
could be used in all transplanted organs
liver kidney heart lung prior to surgical
interventions to minimise the risk of acute
phase rejections 
ophthalmic applications
the group supplies ista pharmaceuticals
inc with hyaluronidase for use in its drug
vitrase
®
 vitrase
®
has been approved by
the us fda for use as a spreading agent
this approval means that for the first time
biozyme will be manufacturing product
which will ultimately be used in a clinical
setting during the year biozyme entered
into a new three year supply agreement
with ista in addition biozyme granted
ista a technology licence to manufacture
hyaluronidase in consideration of this
ista has agreed to pay biozyme a fee of
11m in instalments payable over three
years of which 368000 had been
received in 2004 whilst biozyme has left
the door open for the negotiation of a
new contract it does not anticipate
particularly if ista fails to get vitrase
®
approved for vitreous haemorrhage
supplying ista with product beyond
august 2007 this has clear benefits 
to biozyme freeing up its gmp facility 
to pursue higher value projects 
sepsis and septic shock
ampharma is a joint venture in which
theratase holds approximately 9 of the
equity the venture was established in
2001 to evaluate the role of alkaline
phosphatase in the treatment of sepsis
and septic shock at 30 september 2004
theratase had invested £10m in cash
and inkind contributions which has
assisted ampharma’s clinical progress
alkaline phosphatase represents a potential
major market for ampharma in addition to
the equity stake the group has an exclusive
supply agreement following eventual
approval of the product the programme
has progressed well and has obtained
ethics committee approval to commence
an extended phase iia clinical trial in sepsis
patients the phase i and iia data obtained
to date in the small number of healthy
volunteers indicate the product is safe and
well tolerated the first small phase iia
study using simulated sepsis created 
by giving volunteers low doses of lps
achieved its main aim of demonstrating 
the potential of alkaline phosphatase to
hold back the development of the early
symptoms of septic shock it is expected
that clinical data from the phase iia study 
in 50–60 patients could be available 
in the second half of 2005

“theratase’s 
marketing 
experience has
and will over 
time enhance
seravac’s market
position and 
pricing power” seravac
seravac is an established name in the
diagnostic market and has an ongoing
established trading relationship with
biozyme it operates in similar areas to
biozyme being the production and sale 
of diagnostic and therapeutic enzymes
although seravac and biozyme share
some customers there are few areas
where they are in direct competition
bringing the two businesses together 
has consolidated the group’s position 
as a significant producer and supplier 
of diagnostic enzymes 
seravac operates from a large
manufacturing facility in cape town where 
it employs around 60 staff it produces
approximately 40 different product lines 
all of which are sold outside of south africa
mainly via third party agency agreements
customers include some of the world’s
leading diagnostic and pharmaceutical
companies seravac is an approved
supplier for all its main customers and is
iso 9001 2000 compliant the company
is currently in the process of obtaining
registration with the us fda for good
manufacturing practiceseravac has
historically committed minimal resources 
to marketing and the board believes that
the application of theratase’s marketing
experience has and will over time enhance
seravac’s market position and pricing
power due to the minimal customer
overlap opportunities for crossselling 
and joint marketing initiatives are being
identified particularly in the usa the most
important market for biozyme seravac
manufactures pharmaceutical and
diagnostic enzymes its products may 
be split into two groups animal derived
enzymes and plant derived enzymes
animal derived enzymes
this category includes various proteases
which are enzymes extracted from bovine
pancreas and hyaluronidase which is 
an enzyme extracted from bovine or 
ovine testes the main products are
deoxyribonuclease chymotrypsin 
and chymotrypsinogen which are used 
as antiinflammatory agents as well as
digestive aids
plant derived enzymes
the main product in this category is
peroxidase which is extracted from
horseradish roots and is used in conjunction
with glucose oxidase to monitor glucose
levels in diabetics and as an indicator in
immunodiagnostics to monitor diseases
integration of seravac
in the six months since acquisition
excellent progress has been made in
integrating seravac into the group the
operations of seravac usa have been
combined with those of biozyme’s us
operations and seravac’s us office 
has been closed some management
changes have been made in cape town
to improve the management structure
joint marketing initiatives have
commenced and changes have been
made to technicalmarketing websites 
to facilitate crossselling seravac 
and biozyme use similar production
techniques for extraction and purification
of enzymes and operational synergies

application 08 theratase plc annual report and accounts 2004
chief executive’s review continued
from the sharing of knowledge and
production processes are already being
seen assistance from biozyme has
enabled seravac’s technical staff to make
a significant improvement in production
yields of some of their most important
products these yield enhancements 
have already assisted in achieving an
improvement in seravac’s margins 
scope remains for further improvements
and joint programmes are continuing 
to address both yields and also other
opportunities for joint product ventures
opportunities to rationalise the production
and sale of some products and to
improve the utilisation of plant are being
progressed in addition there may be an
opportunity to enter into joint research
and development projects particularly
in the area of therapeutics
the acquisition has resulted in the
enlarged group being less dependent 
on biozyme’s current two main products
alkaline phosphatase and glucose oxidase
as well as reducing seravac’s reliance 
on pancreatic enzymes the acquisition
has enhanced the group’s strategy of
expanding into the therapeutic enzyme
market as seravac has additional
therapeutic enzyme products to add 
to the group’s existing portfolio
through a number of agency agreements
seravac has a presence in far eastern
markets which are being utilised to assist
biozyme in selling into these areas
similarly biozyme is assisting seravac to
increase sales of its products in europe
the board believes that seravac has
several products which with the benefit
of technological enhancement have
significant growth potential in particular
through the sale of proteases as digestive
aids and food supplements into the far
eastern markets

business performance
the group is one of the few profitable
businesses in the listed diagnostic and
pharmaceutical sector turnover for the
year was £83m 2003 £63m an
increase of 317 seravac contributed

subsidiary are exported at biozyme 69
of turnover is exported mainly to north 
america and the eu at seravac exports
make up 100 of turnover mainly to
europe and the far east during 2004 
sales of alkaline phosphatase have 
been lower than in the previous year
largely because 2003 was boosted 
by a significant order from a us based
customer who typically orders every

particularly to lifescan europe have
strengthened in line with expectations 
operating profit for the group was £17m
2003 £22m of which £02m was

in the short term the board intends that
any future excess profits generated by

the acquisition of seravac has
considerably increased the group’s risk
exposure to foreign currency movements
recognising the need to manage these
foreign exchange exposures the board
has introduced appropriate controls and
procedures the board’s current view is
that hedging strategies do not at present
offer good value for money but this is kept
under constant review
the group entered certain foreign
currency contracts immediately prior to
the acquisition of seravac to manage 
the risk of movements in the south
african rand on the cost of repaying 
local borrowings the net exchange gain
arising of £95000 has been treated as 
a reduction in the borrowings acquired

internal control
the objective of the directors and senior management is to
safeguard the value of the business and assets of the group
part of this objective requires the development of relevant
policies and appropriate internal controls to ensure proper
management of the group’s resources and the identification
of risks which might serve to undermine them
the board acknowledges that it has ultimate responsibility for
the group’s system of internal control and for reviewing their
effectiveness however it is recognised that these systems are
designed to manage rather than eliminate the risk of failure 
to achieve business objectives and can only provide reasonable
but not absolute assurance against material misstatement 
or loss and eliminating the risk of failure to achieve 
business objectives
as prescribed in the guidance of the turnbull committee on
internal control an ongoing process has been established for
identifying evaluating and managing the significant risks faced
by the group this process has been in place throughout the
year in review and up to the date of the approval of the annual
report and accounts
the board has established a risk management committee
the “risk committee” chaired by dr aikman which includes
mr anderson and ms rooke it reviews the risk management
and control processes and reports to the board the risk
committee considers
• the key risks inherent in the business and their identification
evaluation and management
• the effectiveness of the control systems in managing 
those risks
• the response to significant risks which have been identified
• the changes between annual assessments in significant risks
and the group’s ability to respond to changes in the business
environment
• the scope and quality of management’s ongoing monitoring 
of risks
• the communication of monitoring results to the board and
• the actual and potential impact of any risks on financial
performance
the board has reviewed the effectiveness of its systems during
the year in the following key areas
strategy including business strategy the future
direction of the group reputation and value
compliance including compliance with listing rules
director’s duties and general regulatory
compliance
legal including employment risks environmental
health and safety issues intellectual property
insurance risks and cover and acquisitions
financial including detailed budgets plans and
forecasts which are approved by the group
board preparation of business plans which
include the identification of and the
assessment of business risks monitoring of
actual results compared with budgets and
updated forecasts defined procedures for
the appraisal review and authorisation of
capital expenditure
market including market place regulatory changes
customer service and product risks
production including development production and
quality assurance
communication including communication information
technology and website
a corporate risk register is reviewed regularly and updated
annually as a means of identifying and evaluating the significant
risks which may affect the group and the policies and
procedures by which these risks are managed
in view of the current size of the group the risk management
committee believe that the above procedures are adequate and
consequently the creation of an internal audit function is not
deemed necessary
going concern
the directors are of the opinion that the group has adequate
resources to continue in operational existence for the
foreseeable future for this reason they continue to adopt
the going concern basis in preparing the accounts
compliance with the combined code
during the year ended 30 september 2004 the company has
been in compliance with the requirements of the combined
code in place during the year except in the following areas
• the audit committee comprises of two independent non
executive directors and not at least three as is required 
this reflects the current size of the group
• the board believes that given its size and constitution it is
not appropriate to specify a “senior” nonexecutive director 
or to appoint a nomination committee 18 theratase plc annual report and accounts 2004

company’s policy on the remuneration of directors together

remuneration of the other executive directors and senior group
employees and the chief executive is invited to attend the
committee’s meetings but is not present when his own
remuneration is being discussed
the committee meets usually at least twice a year
remuneration policy
the objectives of the remuneration policy for executive directors
are that
• the total remuneration package should be competitive 
with companies in the same sector which are of similar 
size so that it will attract retain and motivate executives 
with the skills and calibre required to maximise return 
for shareholders
• remuneration should align the interests of executives with
those of shareholders through the use of performance driven
cash based awards and share options in addition to base
salary and benefits
•performance targets should be challenging and
• the details of each element of remuneration should be clear
and easily understood
the components of the remuneration of the executive directors
are as follows
base salary
individual base salaries are reviewed annually by the
committee taking into account a number of factors including
individual performance responsibility changes and company
performance base salary is also determined with reference 
to an appropriate comparator group of companies which 
is reviewed annually in this respect specific reference to 
base salary alignment is made to the executive directors’
remuneration in the techmark companies report factors
taken into account for comparison purposes include company
type and sector and measurement of company size by market
capitalisation and turnover
short term incentives – performance bonus
the executive directors are entitled to an annual discretionary
bonus under the executive directors’ bonus scheme the
annual bonus is set at a percentage of base salary on a sliding
scale bonuses are earned on the achievement of gross margin
based on forecast for each 1 of gross margin achieved above
95 of forecast the executive directors are entitled to receive
a discretionary bonus equivalent to 3 of base salary up to a
maximum of 20 of base salary the remuneration committee
determined not to award the executive directors with a bonus
under this scheme during the year
the chief executive under his service contract is entitled 
to an annual performance bonus of between 5 and 10 of 
his base salary subject to his meeting and exceeding agreed
profit targets for the business
in june 2004 the committee determined that the executive
directors should each receive a bonus following the acquisition
of seravac biotech proprietary limited recognising that the
executive directors managed the execution of a large number 
of complex transactions in a relatively short period of time and
showed excellent negotiating skills
share incentive schemes
the company operates an executive share option scheme
executive share option scheme
the executive share option scheme was approved by
shareholders in june 1993 under the scheme rules options
can only be granted within a period of not more than 42 days
after the date on which the annual or half yearly results of the
directors’ remuneration report annual report and accounts 2004 theratase plc 19
company are announced the aggregate maximum amount 
of options which can be granted to an individual is limited to
four times annual salary the maximum number of options that
can be granted in any 10 year period is limited to a number of
shares equal to 10 of the ordinary issued share capital of 
the company options may be exercised between the first and
seventh anniversary of the date of grant the exercise price 
of an option is not less than the mid market price of an
ordinary share on the dealing day preceding the date of grant 
of the options no performance criteria are imposed for
exercising options
the scheme expired in june 2004 since under the rules of 
the scheme no option can be granted to an eligible employee 
at any time after the 10th anniversary of the scheme the last
grant of option to executive directors under the scheme was
made on 28 january 2002
the committee has recently reviewed and taken advice on
possible replacement share incentive schemes on the basis 
of the committee’s advice the board is now proposing to 
adopt the following new schemes
• theratase plc long term incentive plan
• theratase plc savings related share option plan
• theratase plc international savings related share 
option plan

subsidiary undertakings acquired is capitalised as an intangible asset in accordance with frs 10 for acquisitions made after 
1 october 1998 and written off on a straight line basis over its economic life which is 20 years
goodwill arising on acquisitions before 1 october 1998 was written off directly against reserves on acquisition
on the subsequent disposal or termination of a previously acquired subsidiary undertaking the profit or loss on disposal or
termination is calculated after charging the remaining balance of goodwill after amortisation or in respect of subsidiary undertakings
acquired before 1 october 1998 the gross amount of the related goodwill previously written off directly against reserves

notes
forming part of the financial statements 30 theratase plc annual report and accounts 2004
1 accounting policies continued
leasing and hire purchase
where the group enters into a lease which entails taking substantially all the risks and rewards of ownership of an asset the lease 
is treated as a “finance lease” these assets together with assets acquired under hire purchase arrangements are recorded in 
the balance sheet as tangible fixed assets and are depreciated over their estimated useful lives future instalments under such
arrangements net of finance charges are included within creditors rentals payable are apportioned between the finance element
which is charged to the profit and loss account and the capital element which reduces the outstanding obligation for future
instalments
when the group has leasehold property commitments and the group is no longer using the property the directors have made
provision for future commitments at the estimated discounted cost to the group
all other leases are accounted for as “operating leases” and the rentals are charged to the profit and loss account on a straight line
basis over the life of the lease
debt issue costs
in accordance with frs 4 the separately identifiable costs arising on the issue of debt instruments are capitalised and disclosed
within creditors as a deduction from the related debt issue costs are amortised over the life of the debt instruments they relate 
to and the associated charge to the profit and loss account is included as an interest expense
pension costs
the group operates defined contribution pension schemes the amount charged against profits represents the contributions payable
to the scheme in respect of the accounting period the assets of the schemes are held separately from those of the group
fh baxter holdings limited and its subsidiaries operated a defined benefit scheme until the sale of the trade and assets of the
division in march 1996 the scheme has been discontinued and is in the process of being wound up no contributions have been
made since march 1996
seravac biotech proprietary limited provides post employment medical aid benefits to seven retired former employees costs are
assessed using the projected unit credit method
research and development expenditure
the cost of fixed assets acquired to provide facilities for research and development activities is capitalised as tangible fixed assets
and depreciated over the expected useful economic life of the asset concerned research and development expenditure is written 
off against profits in the year in which it is incurred
grants
revenue based grants are credited to the profit and loss account so as to match them with the expenditure towards which they are
intended to contribute capital based grants are credited to the profit and loss account over the estimated useful economic lives of
the assets to which they are related
stocks
stocks are stated at the lower of cost and net realisable value for work in progress and finished goods manufactured by the group
cost includes an appropriate proportion of attributable overheads
taxation
the charge for taxation is based on the result for the year and takes into account taxation deferred because of timing differences
between the treatment of certain items for taxation and accounting purposes deferred tax is recognised without discounting in
respect of all timing differences between the treatment of certain items for taxation and accounting purposes which have arisen 
but not reversed by the balance sheet date except as otherwise required by frs 19
employee share schemes
the cost of awards to employees that take the form of shares or rights to shares is recognised over the period to which the award
relates provision is made for employer’s national insurance contributions which would become due on exercise of these options

the subsidiary is more dependent on the economic environment of the investing company’s currency are translated into sterling at
the rate of exchange on the day the transaction occurs or at the contracted rate if the transaction is covered by a forward exchange
contract monetary assets and liabilities which are denominated in a foreign currency are translated at the rate of exchange ruling at
the balance sheet date and the gains and losses on translation are included in the profit and loss account
the assets and liabilities of all other overseas subsidiary undertakings are translated at the closing exchange rates the profit and
loss accounts of such undertakings are consolidated at the average rate during the year where the translation of the net assets 
and related foreign currency borrowings gives rise to a net exchange difference this is taken directly to reserves

dear shareholder
new employee share plans 
introduction 
resolutions 8 to 13 request shareholders to approve a long
term incentive plan a uk sharesave plan an international
sharesave plan and an employee share ownership plan trust
this letter sets out the reasons for the adoption of the plans and
the circular summarises them 
long term incentive plan “ltip”
the remuneration committee has reviewed the remuneration 
of the company’s senior executives and following independent
advice the committee has decided that a ltip for senior
executives should be recommended for adoption by
shareholders this will replace the company’s 1993 executive
share option scheme which has now expired and which did not
contain performance targets 
the design of the ltip is intended to ensure that the interests 
of senior executives and shareholders are brought more closely
into line over the medium to long term and will incorporate
challenging performance targets the first awards will be granted
shortly after the agm in march 2005 the target applying to the
initial awards will be based upon comparing the growth in the
company’s total shareholder return “tsr” with the tsr of the
companies in the techmark mediscience index over a three year 
performance period ending on 30 september 2007 and will
require the company’s tsr to be in the median or better before
any awards vest 
sharesave plans
the remuneration committee have decided to introduce a uk
sharesave plan which will be approved by the inland revenue
and will be open to all uk employees and an international
sharesave plan to enable all overseas employees to participate
on similar terms these plans replace a previous sharesave plan
which has now expired 
the sharesave plans are designed to give all employees an
interest in the performance of the company 
employee share ownership plan trust
the intention is to source sharesave options and ltip awards
using a combination of new issue and market purchase shares
for this reason it is proposed to introduce an employee share
ownership plan trust “esop” the esop will operate in
conjunction with ltip and sharesave plans it will be able 
to buy shares in the market or subscribe for shares subject 
to certain limits and transfer shares to participants to satisfy
sharesave options and ltip awards

commencing on the date on which the uk saye is approved 
by the inland revenue which will be shortly after it is adopted
by the company in general meeting thereafter invitations may
be issued in the six week period after the date on which the
company releases its results for any financial period or on any
day on which the board resolves that exceptional circumstances
exist which justify the grant of options

but is intended to be used to grant options in conjunction with 
a savings contract to eligible employees outside the uk
the principal terms of the international saye are similar to the
saye except that
• the international saye is not approved by the inland revenue
so it does not qualify for favourable tax treatment
• eligible employees need not be chargeable to uk income tax
• no tax free bonus is payable on completion of the relevant
savings contract but interest is paid on the savings made by
participants
• the participant’s employer may recover any tax or social
security due on the exercise of the option from the participant
unless the participant satisfies that liability himself or has
entered into arrangements to satisfy the liability for example
by the sale of sufficient shares 56 theratase plc annual report and accounts 2004
• the board has discretion to determine whether instead of
delivering shares on the exercise of options the participant
will be paid a sum equal to the difference between the 
market value of the shares on the date on which the option 
is exercised and the exercise price
• options may be adjusted to reflect variations in share capital
and the rules may be amended without the approval of the
inland revenue and
• the board may establish subplans based on the international
saye but modified to take account of local tax exchange
control or securities in different jurisdictions
