Luxembourg, 0423rd April 2003—Vantico Group S.A. (together with Vantico International S.A., "Vantico" or the "Company") announces that it has reached a binding agreement with the ad hoc committee (the "Committee") of holders of the Company's ~~senior~~12% ~~lenders~~Senior ~~have~~Subordinated ~~granted~~Notes andue ~~extension~~2010 to(the ~~existing~~"Senior ~~waivers~~Notes") toand ~~enable~~ the Company's principal toprivate ~~complete~~equity sponsor, Morgan Grenfell Private Equity ("MGPE") regarding the terms of a balance sheet restructuring ~~proposal~~(the as"Restructuring"). ~~described~~The inkey terms of the ~~Company's~~agreement ~~press~~reached ~~release~~with ~~dated~~the Committee 21and ~~March 2003~~MGPE are set out below.

The ~~extension~~Company isbelieves ~~effective~~that, ~~until~~given 16the recent ~~May 2003~~trading environment and based upon current working capital levels, this facility should adequately address the Company's liquidity requirements through the remaining restructuring process.

As the Company announced in its press release dated 29th January 2003, immediately following completion of the proposed restructuring MatlinPatterson Global Opportunities Partners, L.P. ("MatlinPatterson"), a member of the Committee, is expected to become the majority shareholder of the restructured Vantico. The Company has been notified that MatlinPatterson intends to transfer its equity interest in the restructured Vantico to the Huntsman group of companies ("Huntsman"). Vantico expects to benefit from operational and management synergies between Huntsman and the Company.

Helmut Strametz, Chief Executive Officer of Vantico, said:

"We are delighted to announce the completion of this important step in our financial restructuring. All parties have worked hard to put in place a framework which will lead to a significant reduction in the debt burden currently borne by the Company. This will provide the financial strength and flexibility the Company requires to pursue the opportunities present in the markets and to better service its customers."

Peter R. Huntsman, Chief Executive Officer of Huntsman, said:

"We are pleased our partner MatlinPatterson has achieved this milestone in Vantico's financial restructuring. Vantico is globally recognized as an innovator in the specialty chemicals industry, with high quality products and strong growth prospects driven by its leading technology position, excellent application know-how and reputation for providing innovative customer solutions. The specialty nature of Vantico's business would complement Huntsman's existing specialty businesses in polyurethanes, performance chemicals and surfactants. We are delighted to be working with Vantico and MatlinPatterson toward integrating Vantico into Huntsman and welcoming the Vantico associates to the Huntsman group of companies."

The key terms of the proposed restructuring are as follows:

Senior debt refinancing (the "Refinancing")

The Company has now signed commitment letters from two providers of finance. This is expected to result in the restructured Company securing approximately $325 million of new debt finance upon closing of the Restructuring, subject to satisfaction of certain conditions precedent. This new debt finance, together with the proceeds arising from the new share issue described below, will be used to fully repay the Company's existing senior indebtedness. In addition, the two providers of finance have agreed, subject to certain conditions, to provide adequate liquidity lines immediately upon closing.

The Refinancing is conditional on, inter alia, the successful closing of the debt exchange offers described below.

The Senior Notes

All holders of the Senior Notes will be invited to exchange their Notes for ordinary shares in a new holding company for the Vantico group of companies. The holders of the Senior Notes and MGPE, in its capacity as the provider of the short term bridge facility lent to Vantico Group S.A. during 2002 (the "Group Bridge" which amounts to CHF25 million and ranks pari passu with the Senior Notes), will be entitled to receive their pro-rata share, based on principal value, of 95% of the ordinary share capital of the new holding company.

Alternatively, holders of the Senior Notes will be offered a cash alternative in lieu of shares equivalent to €300 per €1,000 of principal value of the Senior Notes outstanding. The members of the Committee, who will be funding the cash alternative, have undertaken not to accept the cash alternative in respect of their holdings of Senior Notes.

The remaining 5% of the ordinary share capital of the new holding company will be offered to holders of the PIK Notes due 2011 and holders of existing equity in Vantico Holding S.A., as described below.

The PIK Notes due 2011 (the "PIK Notes")

Subject to agreement being reached with the stakeholders of Vantico Holding S.A., all holders of the PIK Notes, issued by Vantico Holding S.A., will be invited to exchange their PIK Notes for ordinary shares in the new holding company. The holders will be entitled to exchange their PIK Notes for their pro-rata share, based on principal value of the PIK Notes outstanding, of 2.5% of the ordinary share capital of the new holding company.

Alternatively, the holders of the PIK Notes will be offered a cash alternative in lieu of shares equivalent to up to €20 per €1,000 of principal value outstanding. The cash alternative to the holders of the PIK Notes will also be separately funded by the Committee.

Existing shareholders

Subject to agreement being reached with the stakeholders of Vantico Holding S.A., the existing shareholders of Vantico Holding S.A. together with MGPE, in its capacity as the provider of the bridge facility lent to Vantico Holding S.A. in 2002 (the "Holding Bridge", amounting to CHF50 million and subordinated to the PIK Notes), will be entitled to exchange their existing investment in the Vantico Holding S.A. for their pro-rata share, based on amount invested to date, of 2.5% of the ordinary share capital of the new holding company.

A new shareholder agreement has been negotiated which will provide certain shareholder protections to minority shareholders in the restructured Vantico.

For illustrative purposes the following table sets out the possible equity holdings immediately prior to the New Share Issue and Committee Bridge equitisation (described below) assuming that all parties entitled to take ordinary shares in the new holding company elect to do so.

Stakeholder	Pre New Share Issue
	% of total(1)
The Committee	65.1	%
Other holders of Senior Notes	23.9	%
Group Bridge provider	6.0	%
Holders of PIK Notes	2.5	%
Holding Bridge provider	0.2	%
Existing shareholders	2.3	%
Total	100	%

1.: Assuming an exchange rate of CHF1.4625 to €1. Final exchange rates will be determined three working days before closing of the Restructuring

New share issue

Simultaneous with the debt exchange offers described above, those stakeholders in the Company who elect to receive ordinary shares in the new holding company will be invited to subscribe for their pro-rata share of a new ordinary share issue (the "New Share Issue"). The New Share Issue will raise CHF150 million and is expected to purchase 61.85% of the ordinary share capital of the new holding company following the new Share Issue. The New Share Issue will be priced at a level which implies a 22.5% recovery for the holders of the Senior Notes.

The Committee has agreed to back-stop the New Share Issue in full and will therefore take up any subscription rights not exercised by any other party entitled to do so.

The Committee Bridge

Simultaneous with the closing of the restructuring steps described above, the amount owed under the Committee Bridge will be repaid to the extent possible with available liquidity resources and subject to maintaining certain liquidity levels within the Company. Thereafter any amount owed, but not repaid, will be exchanged for ordinary shares in the new holding company. The issue of these new shares will be at a rate of 0.4% of the then issued ordinary share capital per CHF1 million of Committee Bridge then outstanding. This share issue will dilute all Restructuring participants from their shareholding immediately following the New Share Issue.

The Committee has also agreed to provide a further equity injection of up to $50 million if such equity injection is required to complete the Restructuring in certain circumstances. The issue of such new shares would be at a rate of 1.0% of the then issued ordinary share capital per $1 million invested by the Committee. This share issue would dilute all Restructuring participants from their shareholdings following the New Share Issue and the equitisation of the Committee Bridge.

Implementation

The restructuring steps described above are expected to be implemented through (i) a tender offer by the new holding company to the holders of the Senior Notes; (ii) a private exchange offer between the provider of the Group Bridge and the new holding company; (iii) a private exchange offer between the stakeholders of Vantico Holding S.A. and the new holding company and (iv) a private exchange offer between Vantico Group S.A. and the new holding company. Each of these tender or exchange offers will be conditional upon the closing of the Refinancing and subject to minimum acceptance

conditions of 99%. In the event that the minimum acceptance conditions are not satisfied, the Company expects to utilise a court procedure to effect the proposed transactions. In such circumstances, the Company believes that the offers that would then be made to existing stakeholders would be significantly less attractive than the proposals outlined above.

The Company intends to launch the proposed restructuring steps described above in early May 2003 and anticipates completing the restructuring during the second quarter of 2003.
