                             SUMMARY OF THE OFFER

Atchison Casting UK Limited is offering to buy the issued share capital which 
it has not already agreed to acquire of Sheffield Forgemasters Group Limited.

The Offer is, for each SFG Ordinary Share:

- -    an initial payment of 43.31 pence in cash; and

- -    a further possible payment depending on the amount of additional
     consideration (if any) received by the SFG Group in respect of the

For example:

A shareholder currently holding 100 SFG Ordinary Shares who accepts the Offer 
will receive a payment of L43.31 in cash. He may also receive a further cash 
payment at a later date - there are NO guarantees as to the amount or timing 
of this.

Should you accept the Offer, your cheque in respect of the initial payment 
for your SFG Ordinary Shares will be posted to you within 14 days of the 
Offer becoming or being declared unconditional in all respects (or, if later, 
within 14 days of your acceptance), provided that your share certificate has 
been received.

The board of directors of SFG is unanimously recommending acceptance of the 
Offer.

TO SFG SHAREHOLDERS 

Dear shareholder,

RECOMMENDED OFFER BY ATCHISON 

This document contains an offer by Atchison for the entire issued share 
capital of SFG (except for those shares that Atchison has already agreed to 
acquire). This letter sets out the background to the Offer and explains why 
your Board, which has been so advised by SG Hambros, considers the terms of 
the Offer to be fair and reasonable and is unanimously recommending 
acceptance of the Offer.

THE OFFER

The Offer by Atchison, which is subject to the terms and further conditions 
set out in this document, is made on the following basis:

For every SFG Ordinary Share:

- -    an initial payment of 43.31 pence; and

- -    a further possible payment, depending on the level of the ultimate sale
     proceeds from the Aerospace Transaction.

Atchison's obligation to make the further payment is secured by the Letter of 
Credit.

Further details of the Offer (including the basis of any further payment and 
details of the  payment arrangements) are given in the letter from Atchison 
as set out on pages 7 to 11 of this document.  This also explains the 
procedure for acceptance of the Offer.

BACKGROUND

The SFG Group completed the Aerospace Transaction on 6 February 1998.  Under 
the sale arrangements, the SFG Group received an initial payment of L67.5 
million, L3 million of which is being held as a retention. To the extent that 
the aggregate net assets acquired pursuant to the 


                                     -4-



Aerospace Transaction are above or below L22,513,000, the price for the 
Aerospace Transaction increases or decreases on a pound for pound basis 
accordingly.  The Aerospace Agreement contains detailed provisions dealing 
with the basis and preparation of Completion Accounts to verify such net 
assets.  The Completion Accounts have not yet been finalised, but based on 
the draft accounts provided to the Board by Allegheny Teledyne Incorporated 
it is expected that the SFG Group will receive the full retention of L3 
million plus an additional payment from Allegheny.

The Offer has been structured to pass the benefit of the release of the 
retention and any such additional payment to SFG Shareholders. Accordingly, 
the Committee (comprising of three representatives of the current SFG 
Shareholders) will have absolute authority, inter alia, to negotiate and 
finalise the Completion Accounts on behalf of the SFG Group (including, where 
appropriate, to take legal proceedings) and agree with Atchison the amount 
(if any) of the additional consideration to be paid to SFG Shareholders under 
the Offer.

MANAGEMENT AND EMPLOYEES

The Atchison Board has confirmed that the existing employment rights, 
including pension rights, of the management and employees of the SFG Group 
will be fully safeguarded and it has confirmed that it is the intention of 
Atchison to develop the SFG Group's businesses as an important part of the 
Atchison Group.

Once the Offer becomes or is declared unconditional in all respects I and the 
remaining members of the Board, save for David Fletcher, will resign.  

IRREVOCABLE UNDERTAKINGS

The directors, certain members of our families and related interests together 
with other SFG Shareholders (including the NatWest Funds and the Schroder 
Funds) have irrevocably undertaken to accept the Offer in respect of a total 
of at least 58,857,680 SFG Ordinary Shares (representing approximately 77.73 
per cent of the issued SFG Ordinary Share capital to which the Offer relates).

THE EXCHANGE AGREEMENT AND THE DEED OF WARRANTY AND UNDERTAKING

Pursuant to the Exchange Agreement, David Fletcher and certain senior 
managers of the SFG Group and members of their families have agreed to sell a 
proportion of their holdings of SFG Ordinary Shares (representing, in 
aggregate, 1.64 per cent of the issued share capital of SFG) in return for 
the issue to them of new ordinary shares in Atchison, representing, in 
aggregate, approximately 5 per cent of the issued share capital of Atchison 
following the Offer (instead of the initial payment of consideration to which 
they would have otherwise been entitled under the Offer) plus a cash payment 
equal to the additional payment per SFG Ordinary Share that is subsequently 
paid to SFG Shareholders under the Offer. Further details of the Exchange 
Agreement are contained in paragraph 4 of Appendix II of this document.

Under the Deed of Warranty and Undertaking, David Fletcher, Malcolm Brand and 
Phillip Wright (a former director of SFG) have agreed to give certain 
warranties to Atchison regarding 


                                     -5-



the business and assets of the SFG Group and Atchison has agreed to the 
Committee finalising and agreeing the Completion Accounts and, where 
appropriate, taking legal proceedings. Further details of the Deed of 
Warranty and Undertaking are contained in paragraph 5 of Appendix II of this 
document.

Save for the Exchange Agreement and Deed of Warranty and Undertaking, the 
directors do not have any material interest in any contract entered into by 
any member of the Atchison Group.   

ADDITIONAL INFORMATION

A copy of the latest published audited accounts for SFG, being those to 31 
March 1997, is enclosed.  Since the date to which such accounts were prepared 
SFG has entered into the Aerospace Transaction, redeemed 113,385,528 
preferred ordinary shares of 30 pence and repaid its term loan in the 
principal sum of L35 million from the Bank of Scotland.  The prospects for 
SFG during the current financial year have been adversely affected by the 
strength of sterling.

Save as set out above, there has been no material change in the financial 
position or prospects of SFG since 31 March 1997, being the date to which the 
last audited accounts were prepared.

Details of the directors' interests (if any) in the shares of SFG and 
Atchison are set out in paragraph  2(i) of Appendix II of this document.

Your attention is drawn to the contents of the remainder of this document.

RECOMMENDATION

THE DIRECTORS OF SFG, WHO HAVE BEEN SO ADVISED BY SG HAMBROS, CONSIDER THE 
TERMS OF THE OFFER TO BE FAIR AND REASONABLE. IN PROVIDING ADVICE TO THE 
DIRECTORS, SG HAMBROS HAS TAKEN ACCOUNT OF THE DIRECTORS' COMMERCIAL 
ASSESSMENTS.

THE DIRECTORS UNANIMOUSLY RECOMMEND ALL SFG SHAREHOLDERS TO ACCEPT THE OFFER.

Yours faithfully

TO SFG SHAREHOLDERS 

Dear Sir or Madam,

RECOMMENDED OFFER FOR SFG

1    INTRODUCTION

     Atchison has decided to make an offer for all the SFG Ordinary Shares 
     which it has not already contracted to acquire pursuant to the Exchange 
     Agreement. This document contains the Offer.  A Form of Acceptance to be 
     used in connection with the Offer is enclosed.

2    RECOMMENDATION

     Your attention is drawn to the letter from your Chairman on pages 4 to 6 
     of this document in which it is stated that the directors of SFG 
     unanimously recommend SFG Shareholders to accept the Offer. 

3    INFORMATION ON ATCHISON AND BACKGROUND TO THE OFFER

     Atchison is a newly formed company acquired by the Atchison Group for 
     the purpose of making the Offer. It is a wholly owned subsidiary of 
     Atchison Casting Corporation.  It has not traded and has not prepared 
     any accounts for any period.  The issued share capital of Atchison is 
     L10.45 million.

     Atchison Casting Corporation was formed in 1991 and is based in 
     Atchison, Kansas, USA and is the holding company for the Atchison Group. 
     The Atchison Group is a manufacturer of iron, steel and nonferrous 
     castings in a wide range of sizes and alloys. The Atchison Group 
     currently employs more than 3,000 people and serves more than 400 
     customers. It is estimated that annual sales for the current fiscal year 
     will exceed $300 million. Atchison Casting Corporation's shares are 
     traded on the New York Stock Exchange.  

     As the foundry and casting industries consolidate, the strategy of the 
     Atchison Group has been to buy foundries, die casters, forges and 
     machine shops and to sponsor and 


                                     -7-



     encourage the introduction of technology for the design and production of 
     cast and forged components which are lighter, stronger and more efficient.

     To date, the Atchison Group has acquired 15 foundries and die casters, 
     with five machine shops, in the United States and Canada. The 
     acquisition of SFG will expand the Atchison Group's product range into 
     forgings and ingot and into rolls for steel, aluminium, paper and 
     plastic processing. The acquisition will also increase the range of 
     casting size which the Atchison Group can deliver at the top end of the 
     market.  The skilled workforce and experienced technical staff in the 
     SFG Group are a very important part of the acquisition, and will bring a 
     wealth of knowledge to the Atchison Group which it is hoped will enhance 
     its position within the foundry and casting industries.  Atchison hopes 
     that SFG will be a springboard into other international markets for the 
     Atchison Group, which up to now has operated primarily in the United 
     States and Canada.

4    THE OFFER

     Atchison offers to acquire, on the terms and subject to the conditions 
     set out in this document and in the Form of Acceptance, all the SFG 
     Ordinary Shares (other than those which it has contracted to acquire 
     pursuant to the Exchange Agreement) on the following basis:

     For each SFG Ordinary Share:

     -    an initial payment of 43.31 pence in cash; and

     -    a further payment depending on the amount of the Aerospace 
          Additional Payment (the "ADDITIONAL CONSIDERATION"). 

     The aggregate initial payment due to each SFG Shareholder will be 
     rounded down to the nearest whole penny.

     The Additional Consideration per SFG Ordinary Share shall be a pro rata 
     amount (based on the number of SFG Ordinary Shares in issue as at the 
     date of this document) of the aggregate of:
     
     -    an amount equal to the Aerospace Additional Payment 

     PLUS

     -    an amount equal to any interest which shall have accrued on the 
          Aerospace Additional Payment from the date of payment or discharge to
          the SFG Group (or as it may otherwise direct) and the date preceding 
          the day when the Additional Consideration  is paid to SFG Shareholders

     LESS

          Atchison Group in connection with the issue of the Letter of Credit as
          agreed by the Committee in its sole discretion (such agreement not to 
          be unreasonably withheld or delayed)

     LESS

     -    an amount equal to all external costs, fees and expenses incurred 
          by the SFG Group in relation to the Offer, the Aerospace Transaction 
          or related matters which are agreed by the Committee in its sole 
          discretion

     LESS

     -    an amount equal to all external costs, fees and expenses incurred 
          by SFL and/or the Committee in the agreement and determination of the

          and/or the Additional Consideration (including those of the Security 
          and Payment Agent) as agreed by the Committee in its sole discretion

     LESS

     -    an amount equal to the stamp duty payable by Atchison in respect of 
          the Additional Consideration. 

     Any Additional Consideration will be paid to the Security and Payment 
     Agent for distribution to SFG Shareholders on or before the date which 
     is seven days after the later of the date which is seven weeks from the 
     date when the Offer becomes or is declared unconditional in all respects 
     and the date upon which payment or discharge of the Aerospace Additional 
     Payment  to the SFG Group (or as it may otherwise direct) is made in 
     accordance with the terms of the Aerospace Agreement and the CTS 
     Agreement.  

     Harris Trust and Savings Bank in Chicago, the United States has issued 
     the Letter of Credit to the Security and Payment Agent for the benefit 
     of all SFG Shareholders as at the date of this document such that in the 
     event that Atchison does not pay the Additional Consideration and/or the 
     cash due under the Exchange Agreement within seven days of its due date, 
     the Bank will (subject to the terms of the Letter of Credit) make such 
     payment to the Security and Payment Agent on behalf of the relevant SFG 
     Shareholders, up to a maximum amount of L9,000,000 in aggregate.

     The Committee shall, in its sole discretion, authorise the Security and

     non-payment.

     respects:

     (i)    the appointment of the Security and Payment Agent to act as his 
            agent with respect to the receipt and settlement of the whole or 
            part of the consideration due under the Offer and the Letter of 
            Credit and an irrevocable authority to the Security and Payment 
            Agent on such SFG Shareholder's behalf to:

            (a)  receive the consideration due under the Offer and/or the 
                 proceeds of any drawing under the Letter of Credit on behalf 
                 of such SFG Shareholder and to pay such consideration and/or 
                 proportionate share of such proceeds to such SFG Shareholder

                 rely and shall be fully protected in so doing), to draw upon 
                 or cancel the Letter of Credit and to take all such steps 
                 for such purpose as the Security and Payment Agent may, in 
                 its absolute discretion, determine, provided that the 
                 Security and Payment Agent shall not make any drawing upon 
                 the Letter of Credit to the extent that the Security and 
                 Payment Agent has actually received an unconditional and 
                 irrevocable payment of cleared funds into the client account 
                 of Dibb Lupton Alsop held at National Westminster Bank plc, 
                 Sheffield, account number 58076 in respect of the 
                 obligations of Atchison which are covered by the Letter of 
                 Credit. (For the avoidance of doubt, if any such payment so 
                 received satisfies the obligations of Atchison which are 
                 covered by the Letter of Credit in part only, the Security 
                 and Payment Agent shall be entitled to draw upon the Letter 
                 of Credit to the extent of the then unsatisfied obligations);

     (ii)   an acknowledgement that, in the exercise of any right or power 
            provided for in this Appendix 1, the Security and Payment Agent 
            shall act in accordance with the instructions of the Committee 
            (subject to the provisions of Clause 12(i)(c)) or as this 
            Appendix 1 may require and shall be fully protected in so doing, 
            and in the absence of any such instructions and/or relevant 
            requirement contained in this Appendix 1, the Security and 
            Payment Agent may act or refrain from acting with respect to such 
            right or power as it shall see fit;

     (iii)  an acknowledgement and agreement that the relationship between 
            the SFG Shareholders and the Security and Payment Agent is that 
            of principal and agent and nothing herein shall constitute the 
            Security and Payment Agent a trustee or fiduciary for such SFG 
            Shareholder or any other person;

     (iv)   an agreement that the Security and Payment Agent shall not be 
            liable to the SFG 


                                     -16-



            Shareholders for any breach by Atchison of its obligations under 
            the Offer or for any breach by the issuing bank of its obligations 
            under the Letter of Credit;

     (v)    an agreement that the Security and Payment Agent may act through 
            its personnel and through agents selected by it with reasonable 
            care (who shall be entitled to the same protections as those 
            given to the Security and Payment Agent hereunder);

     (vi)   an agreement and acknowledgement that the Security and Payment 
            Agent shall not be required to ascertain or enquire as to the 
            performance or observance by Atchison of the terms of the Offer 
            and that nothing herein contained shall oblige the Security and 
            Payment Agent to threaten, take or institute any legal action or 
            any other proceedings on behalf of the SFG Shareholders and that, 
            until the Security and Payment Agent shall have received 
            instructions from the Committee to do so, it shall not be 
            required to take any action to draw on or cancel the Letter of 
            Credit;

     (vii)  an agreement and acknowledgement that neither the Security and 
            Payment Agent nor any of its officers, shareholders, employees or 
            agents shall be liable to the SFG Shareholders for any action 
            taken or omitted to be taken under or in connection with the 
            Letter of Credit unless caused by its or their negligence or 
            wilful misconduct;

     (viii) an agreement and acknowledgement that the Security and Payment 
            Agent may rely on any communication or document reasonably 
            believed by it to be genuine or correct;

     (ix)   an agreement to indemnify the Security and Payment Agent on 
            demand for any and all liabilities, losses, damages, penalties, 
            actions, judgements, costs, expenses or disbursements of any kind 
            whatsoever which may be imposed on, incurred by or asserted 
            against the Security and Payment Agent or any of its officers, 
            shareholders, employees or agents in any way relating to or 
            arising out of its acting as such Security and Payment Agent or 
            performing its duties in connection therewith or any action taken 
            or omitted to be taken by such Security and Payment Agent 
            thereunder including, without limitation, the normal 
            administrative costs and expenses incidental to the performance 
            of its agency duties hereunder (such indemnification by such SFG 
            Shareholder shall be pro rata to his entitlement to the 
            consideration payable under the Offer) and an authority to the 
            Security and Payment Agent to deduct from any monies received by 
            it on behalf of the SFG Shareholder and retain for its own 
            benefit any and all amounts due under this paragraph or otherwise 
            (together with any applicable value added or other tax); and

     (x)    an agreement that the Security and Payment Agent may refrain from 
            doing anything which would or might in its reasonable opinion:

            (a)  be contrary to the law of any applicable jurisdiction or any 
                 applicable official directive; or

            (b)  render it liable to any person

            and may do anything which in its reasonable opinion (acting on 
            legal advice) is necessary to comply with any such law or directive.

     to the person or persons executing a Form of Acceptance and, in the 
     event of more than one person executing a Form of Acceptance, the

                 otherwise than by subscription are held by or on behalf of

                 shareholder of SFG or any person who has been such a 
                 director or shareholder at any time during the period of 12 
                 months immediately preceding the date of the Offer, being an 
                 agreement or arrangement which is connected with or 
                 dependent on the Offer.  

            (c)  There is no agreement or arrangement by which any shares or 
                 debentures acquired by Atchison in pursuance of the Offer 
                 will or may be transferred to any other person. 

            (d)  There have been no dealings in the shares or debentures of 
                 Atchison 


                                     -20-



                 during the period of 12 months immediately preceding the date 
                 of the Offer by any person who was a director of Atchison at 
                 any time during that period.

            (e)  There are no service contracts between Atchison and its 
                 directors which have or are capable of having a duration of 
                 more than one year.  

3    MISCELLANEOUS

     (i)    If it becomes entitled so to do, Atchison intends to acquire the 
            shares of any dissenting minority of SFG Shareholders under the 
            compulsory acquisition procedures in part XIIIA of the Companies 
            Act 1985. 

     (ii)   Upon the Offer becoming or being declared unconditional in all 
            respects all of the existing members of the Board of SFG, save 
            for David Fletcher, will resign. It is estimated that the 
            aggregate amount which will be payable in respect of severance 
            payments to resigning members of the SFG Board will be 
            approximately L220,000.  David Fletcher is to receive a bonus of 
            L150,000 (including employer's national insurance).

     (iii)  Save as detailed in paragraph (ii) above it is not proposed, in 
            connection with the Offer, that any payment or other benefit be 
            made or given to any director or former director of SFG in 
            connection with or as compensation or consideration for his 
            ceasing to be a director or to hold any office held in 
            conjunction with a directorship or, in the case of a former 
            director, to hold any office which he held in conjunction with 
            his former directorship and which he continued to hold after 
            ceasing to be a director.  The acquisition of the SFG Ordinary 
            Shares to which the Offer relates is not conditional upon the SFG 
            Shareholders approving or consenting to, any such payment or 
            benefit being made or given.
          
     (iv)   Atchison has no reason to believe that there has been any 
            material change in the financial position or prospects of SFG 
            since 31 March 1997 other than that referred to in the Additional 
            Information section of the SFG Chairman's letter on page 6 of 
            this document.

4    SUMMARY OF THE EXCHANGE AGREEMENT 

     Under the Exchange Agreement, David Fletcher and certain senior managers 
     of the SFG Group (the "Managers") and members of their families have 
     agreed to sell a proportion of their holdings of SFG Ordinary Shares 
     (representing, in aggregate, 1.64 per cent of the issued share capital 
     of SFG) in return for, first, the issue to them of new ordinary shares 
     in Atchison, representing, in aggregate, approximately 5 per cent of the 
     issued share capital of Atchison following the Offer and, second, a cash 
     payment equal to the Additional Consideration per SFG Ordinary Share 
     which is paid to SFG Shareholders under the Offer.  Upon completion of 
     the Exchange Agreement, David Fletcher, will hold 3% of Atchison's 
     issued share capital.


                                     -21-



     The Exchange Agreement contains certain warranties on the part of the 
     Managers and their families and Atchison.

     The Exchange Agreement is conditional upon the Offer becoming or being 
     declared unconditional in all respects on or before 30 April 1998 and 
     Atchison having been registered as the holder of at least 50 per cent of 
     the SFG Ordinary Shares.  The Exchange Agreement will be completed as 
     soon as these conditions are satisfied.  If the conditions are not 
     satisfied on or before 30 April 1998 the Exchange Agreement will cease 
     to be of effect.

     Each of the Managers will be granted an option to acquire at nominal 
     value further shares in Atchison up to the number of shares issued to 
     them and their families in return for their SFG Ordinary Shares.  The 
     option is generally exercisable as to one fifth at the end of each of 
     years one to five from the date of completion of the Exchange Agreement, 
     provided that at the relevant time the relevant Manager continues to be 
     employed by Atchison.  The option is exercisable earlier upon the sale 
     or flotation of Atchison or SFG.

     Between the fifth and tenth anniversary of completion of the Exchange 
     Agreement the Managers and their families will have the option to 
     exchange all of their Atchison shares (including those issued pursuant 
     to the options) for shares in Atchison Casting Corporation having a net 
     asset value (determined by reference to the most recent management 
     accounts of Atchison Casting Corporation) equal to 85% of the net asset 
     value of the Atchison shares exchanged.

5    SUMMARY OF THE DEED OF WARRANTY AND UNDERTAKING 

     Under the Deed of Warranty and Undertaking David Fletcher, Malcolm Brand 
     and Phillip Wright (the "Covenantors") have irrevocably undertaken to 
     accept the Offer and have given certain further undertakings regarding 
     the operation of the business of the SFG Group pending the Offer 
     becoming or being declared unconditional in all respects.  In addition, 
     the Covenantors have agreed to give certain warranties (subject to 
     agreed limitations on the amounts which may be claimed under those 
     warranties and the time period in which claims may be brought) to 
     Atchison regarding the business and assets of the SFG Group and a deed 
     of covenant (subject to similar limitations) regarding taxation which 
     may be payable by the SFG Group in respect of periods prior to the Offer 
     becoming so unconditional.

     Malcolm Brand and Phillip Wright have also given covenants under which 
     they agree not to be involved in any business competing with that of the 
     SFG Group until 31 December 1998.

     Atchison has agreed that the Committee will have absolute authority to 
     negotiate and finalise the Completion Accounts on behalf of the SFG 
     Group and recover the Aerospace Additional Payment (including authority 
     to litigate).

     The Deed of Warranty and Undertaking will cease to be of effect if the 
     Offer lapses or is withdrawn.


                                     -22-



6    SUMMARY OF AEROSPACE AGREEMENT

     Under the Aerospace Agreement, SFL agreed to sell the entire issued 
     share capitals of Forgemasters Inc, Jessop Saville Limited, SMP Metals 
     Inc and Special Melted Products Limited for an initial consideration of 
     L67.5 million plus the Aerospace Additional Payment (which includes a L3 
     million retention from the initial payment of L67.5 million).  David 
     Fletcher, Malcolm Brand and Phillip Wright gave certain warranties 
     (subject to agreed limitations on the amounts which may be claimed under 
     those warranties and the time period in which claims may be brought) to 
     the other parties to such agreement regarding the business and assets of 
     the companies sold and those of CTS sold under the CTS Agreement. They 
     also gave a deed of covenant (subject to similar limitations) regarding 
     taxation which may be payable by the companies sold in respect of the 
     periods prior to completion of the agreement.

     Malcolm Brand and Phillip Wright also gave covenants under which they 
     agreed  not to be involved in any business competing with the businesses 
     of the companies sold or the businesses of CTS until 31 December 1998.
