REPORT FROM THE CHAIRMAN AND THE CHIEF EXECUTIVE OFFICER

2008 was a landmark year for ImmuPharma plc which culminated in November 2008 in a transaction worth up to $500m in cash milestone payments in addition to significant royalties, with Cephalon Inc, an S&P500 company, for the worldwide development and commercialisation of our lead compound LupuzorTM. ImmuPharma has to date received $45 million in cash from Cephalon, of which $15 million was paid in Q4 2008 on the signing of the option agreement and $30 million in Q1 2009 on exercise of the option to license the worldwide rights to LupuzorTM . Cephalon is now responsible for all costs associated with its development and commercialisation. Cephalon and ImmuPharma have established a joint committee to oversee these activities.

Since the deal was announced, LupuzorTM successfully completed its ongoing phase IIb clinical trial in patients suffering with Systemic Lupus Erythematosus.

During Q1 2008 ImmuPharma entered the field of cancer therapy following the licensing of a novel cancer compound from ImmuPharma’s research partner, the Centre National de la Recherche Scientifique ("CNRS"). The lead compound, IPP-204106, has since shown outstanding preclinical data confirming the ability of the series of compounds to effectively control and stop the growth of a large panel of human cancer cell lines both "in vitro" and "in vivo". Collectively the studies comprised breast cancer, prostate cancer, melanoma, glioblastoma, leukaemia, colon cancer and pancreatic cancer cell lines.

In addition, we were proud to receive two grants totalling €1.15 million from prestigious French institutions to expedite the development of our cancer programme.

In early Q3 2008, we attracted new blue-chip institutional shareholders from the UK and Switzerland by way of a placing totalling £2.7m, before deduction of placing costs.

Our strong balance sheet enables us to maximise the value of our pipeline, including the novel cancer compound, a compound for the treatment of serious pain, a novel antibiotic for MRSA and our library of patented drug candidates, while LupuzorTM continues to progress through our partnership with Cephalon.

The Board of ImmuPharma plc would like to thank its partners, Cephalon and the Centre Nationale de la Recherche Scientifique in France for their collaboration and its shareholders for their continuing support during 2008.

REPORT FROM THE CHIEF SCIENTIFIC OFFICER

2008 was a year of exciting progress for ImmuPharma with the achievement of notable, key milestones. The pivotal, double-blind, placebo-controlled Phase IIb trial for LupuzorTM yielded statistically significant positive data in its interim analysis. ImmuPharma successfully concluded an option agreement with Cephalon, Inc. for LupuzorTM which has subsequently been exercised bringing the Company $45m in cash. Data for IPP-204106 has confirmed the ability of the programme to effectively control and stop the growth of a large panel of human cancer cell lines both “in vitro” and “in vivo”. €1.15m of grants have been awarded for the advancement of the cancer programme from prestigious French national institutions. With a successful share placement in the summer and the payments from Cephalon, Inc for LupuzorTM, the Group is well-placed to continue the development of all of its development assets.

The past year has seen a number of key developments for LupuzorTM our lead drug candidate for the treatment of lupus, a chronic, life-threatening autoimmune disease. These developments include: LupuzorTM completing the mandatory long term toxicology study package with no clinical or laboratory findings to suggest any safety issues. The LupuzorTM patent was approved in Japan and Australia and received notice of allowance from the US Patent Office, and ImmuPharma also received approval of the trademark name LupuzorTM by the US Patent and Trademark Office.

Importantly, the mechanism of action of LupuzorTM has been identified by researchers working with ImmuPharma at the Centre National de la Recherche Scientifique in Strasbourg. LupuzorTM has shown that it modulates, through a unique mechanism, a specific subset of CD4 T cells which play a critical role in the physiopathology of Lupus. A new patent which covers this discovery has been filed. This mechanism is consistent with and explains the very favourable safety profile of LupuzorTM (maintenance of the overall immune system while being effective) and its activity as a specific immune-modulator.

Furthermore, during the LupuzorTM’s Phase IIB study, an interim analysis was performed and reviewed by an independent Data Monitoring Committee according to ICH guidelines. This interim analysis demonstrated statistically significant superiority of LupuzorTM over placebo. This analysis was conducted after 125 randomised patients had completed the 12 week treatment period, half of them having also completed the additional 12 week follow up (week 24). The primary efficacy measure was a ‘SLEDAI response’ defined as a decrease of at least 4 points in the SLEDAI score, a scale generally accepted by physicians as an assessment of the clinical activity of Lupus patients, a lower score representing lower disease activity. The analysis of the data has demonstrated that the 200mcg dose of LupuzorTM administered every four weeks was statistically significantly superior to placebo (p=0.015). LupuzorTM was generally well-tolerated with no significant drug related adverse events recorded. This data follows on from the successful results which we observed with the preliminary Phase IIa trial.

In November, ImmuPharma was delighted to announce the signature of an option agreement with Cephalon, Inc. to obtain an exclusive, worldwide license to LupuzorTM. With the data arising from the interim analysis, Cephalon decided to exercise their option thereby assuming all expenses for Phase III studies and subsequent commercialisation of the product. We are delighted to have formed this partnership with Cephalon and to have secured the future development for LupuzorTM. The $45m cash arising from the signature of the option agreement and its subsequent exercise has provided a valuable cash base on which to further develop our other pipeline assets.

During the year, data on ImmuPharma’s anti-cancer nucleolin antagonist (“Nucant”) peptide programme, IPP-204106 was obtained confirming the ability of the compounds to effectively control and stop the growth of a large panel of human cancer cell lines both “in vitro” and “in vivo”. Collectively the studies comprised breast cancer, prostate cancer, melanoma, glioblastoma, leukaemia, colon cancer and pancreatic cancer cell lines. "In vivo" studies showed that tumours were completely eradicated and survival time increased without additional treatment. ImmuPharma has filed appropriate patents on the composition of matter relating to the peptides covering a large variety of Nucant structures. Manufacturing processes transferable to large scale production have also been successfully developed. Due to the considerable progress made, ImmuPharma has initiated the regulatory studies necessary for the development program of IPP-204106, and has applied for and successfully been awarded €1.15m of prestigious grants from French national research agencies.

While our core strategy is to focus on the progression of our Lupus and cancer compounds, we are also progressing our other lead candidates. Our two other lead drug candidates each represent a breakthrough approach and are very exciting compounds that fit perfectly with the Company’s model of niche diseases.

On behalf of the Board we would also like to extend our particular thanks to the team at the CNRS in Strasbourg with whom ImmuPharma has key collaborations.

Financial Review

The year ended 31 December 2008 had several notable financial milestones. The Group successfully raised £2.7m of new funds through a share placing with both UK and Swiss institutional investors in difficult market conditions. With our promising cancer program, the Group was awarded €1.15m of grants from prestigious French research agencies to further its development.

Furthermore, the Group entered into an option agreement with Cephalon, Inc in November which was exercised in February 2009 providing a total of $45m in cash. Coupled with the Group’s continued emphasis on controlled expenditure for the development of its assets, these additional funds will help secure the development of the Group through the next few years.

The Group continues to adopt International Financial Reporting Standards (IFRS) as its primary accounting basis.

Financial results for the period

The Operating Loss of £4.6m represents principally the expenditure on development carried out by Contract Research Organisations and the employment and running costs of the Group. The timing and extent of the research and development programme continues to be well controlled.

Research and development expenditure was £2.8m while administrative expenses were £1.8m. Research and development expenditure has risen in line with the progression of the Group’s assets, in particular the Phase IIb trial of LupuzorTM. Administrative expenditure increased slightly from previous years in line with expectations.

However, with the completion of the option agreement with Cephalon, Inc for LupuzorTM, the Group achieved a profitable position for the first time with a profit before tax for the year of £4.9m. The profit of the Group for the period after tax was £4.7m (compared to a loss of £3.1m for the year ended 31 December 2007).

Basic and diluted earnings per share was 6.23p and 5.72p respectively (prior period loss per share of 4.24p). No dividend is proposed.

In previous years, IFRS2, relating to share-based payments has had an impact on the Group’s results. While no new options were granted in 2008, there is a charge in the accounts of £97,730 which represents the current year charge for options previously granted. This is purely a notional amount stipulated by IFRS2 (and calculated using a statistical model) as a result of granting the options. A further £153,963 is due to be charged in the following years accounts under IFRS2, being the remainder of the fair value charge.

Net Funds

At 31 December 2008, the Group had cash and cash equivalents of £12.5M (31 December 2007 was £2.9M). Furthermore, in February 2009, Cephalon, Inc exercised their option to license LupuzorTM for a payment of $30m in cash, thereby further strengthening the Group’s cash position.

Treasury Policy

The policy continues to be that surplus funds of the Group are held in interest-bearing bank accounts on short or medium maturities, until commitments to future expenditure are made, when adequate funds are released to enable future expenditure to be incurred. The Group’s Treasury Policy and controls are straightforward and approved by the Board. The Group does not engage in speculative transactions.

Financial Strategy

The expenditure of the Group has been directed towards progressing its assets through clinical development to maximise their potential.

The overall strategy is to maintain a tight control over cash resources whilst enabling controlled development of the potential product portfolio. The Board remains alert to opportunities to raising further finance.
