(a) to make as promptly as reasonably practicable and in accordance with any applicable time limits (and any extension thereof that may be granted), all such notifications or filings with any appropriate Relevant Authorities, whether jointly or separately (as may be required by applicable law), as Bidco reasonably considers are necessary or desirable for the implementation of the Acquisition, the obtaining of the Clearances and/or the satisfaction of the Conditions;

(j) following each of the Meetings and assuming the necessary resolutions are passed by the requisite majorities, as soon as reasonably practicable (and in accordance with the Timetable and this Agreement) take all necessary steps to seek the sanction of the Court to the Scheme (unless Bidco has notified Intec in writing that an event has occurred or a circumstance has arisen which Bidco considers is sufficiently material for the Panel to permit it to withdraw from the Acquisition), and take any other action reasonably necessary to implement the Acquisition (including, for the avoidance of doubt, reconvening the Court Meeting and any other necessary shareholder meetings if so required by the Court);

(k) subject to applicable confidentiality, legal and regulatory requirements, co-operate with and provide such details to Bidco in relation to the Intec Share Schemes as Bidco reasonably requires in order to plan and make proposals to the participants of the Intec Share Schemes and, if necessary, to communicate with such participants in respect of such proposals;

8. CONDUCT PENDING COMPLETION OF THE ACQUISITION

8.1 Pending the Acquisition Effective Date, and without prejudice to Rule 21 of the City Code and subject to all applicable legal and regulatory requirements, Intec shall and shall procure that each member of its Group shall:

(a) carry on its businesses in the ordinary course and, unless in accordance with the terms of existing arrangements entered into prior to the date of this Agreement or with the consent of Bidco, shall not undertake any material commitment or enter into any material contract (other than in connection with sales contracts of a revenue generating nature) or acquire or dispose of any material assets, liabilities or businesses. For the purposes of this clause 8.1(a), a matter shall be material if, in a single transaction or a series of related transactions, it amounts to or exceeds an aggregate amount of £2.5 million;

(b) disclose to Bidco as soon as reasonably practicable any matter of which it is aware which is reasonably likely to constitute a breach of any of the Conditions or result in any of them not being satisfied in the timescale contemplated by the Timetable, or otherwise result in a delay in the Timetable;

(c) once the Acquisition Document has been circulated to Intec Shareholders, except as required by law or by the Panel (after any rights Bidco may have to appeal a Panel ruling have been exhausted), not make any amendment or addition to, or otherwise vary, the terms of the Acquisition Document without the prior written approval of Bidco; and

(d) not:

(i) change the general terms of employment of its employees or the terms of employment of its directors in any way, other than in the ordinary course of business;

(ii) adopt or amend any employee benefit, bonus or profit sharing scheme (including without limitation any scheme having share purchase or share option provisions);

(iii) enter into any arrangements with the trustees of any pension scheme, in which it or any member of its Group participates, to pay employer contributions to such scheme other than those employer contributions agreed with the trustees as at the date of this Agreement, save as required by law or regulation or the rules of any such scheme;

Page 13

(iv) recommend, declare, announce, pay or make or propose the recommendation, declaration, payment or making of, any bonus, dividend, or other distribution to its shareholders without the prior written consent of Bidco;

(v) except in respect of options granted at the date of this Agreement under the Intec Share Schemes and save as contemplated pursuant to the Scheme, alter the authorised or allotted or issued share capital of Intec, nor grant any options or other rights to subscribe for any shares under the Intec Share Schemes, without the prior written consent of Bidco;

(vi) other than as contemplated by clause 8.4, amend the memorandum or articles of association of any member of Intec’s Group;

(vii) otherwise take any action which it knows would or might reasonably be expected to be prejudicial to the successful outcome of the Acquisition or which would or might reasonably be expected to have the effect of preventing any of the Conditions from being fulfilled or resulting in a delay to the Timetable;

(viii) enter into any loan agreement with any bank or other financial institution, issue any debt securities or (otherwise than in the ordinary course of business) incur any other indebtedness;

(ix) repay, accelerate or otherwise amend the terms of any indebtedness of any member of the Intec Group otherwise than in the usual course of carrying on its business or cancel any facilities available to Intec; or

(x) agree to do any of the above.

8.2 Intec undertakes that, except with the prior written consent of Bidco, it will not agree, announce or submit to its shareholders for approval in general meeting any resolution in relation to a Major Transaction.

8.3 Intec shall promptly notify Bidco if Intec becomes aware of any act, matter or thing inconsistent with its obligations contained in clause 8.1.

8.4 Intec shall propose to Intec Shareholders such changes as Bidco may reasonably require to Intec’s articles of association in order to implement the Acquisition in relation to holders of options under the Intec Share Schemes.

8.5 Intec agrees that:

(a) it shall not, and shall procure that no Intec Connected Person shall, directly or indirectly, solicit, initiate or otherwise seek to procure any Competing Proposal or Major Transaction (provided that the above shall not prevent it or any Intec Connected Person from responding to or dealing with any unsolicited offer, proposal, enquiry or approach which the Intec Directors reasonably consider to be bona fide);

(b) except in circumstances consistent with the proviso in clause 8.5(a) it shall not, and shall procure that no Intec Connected Person shall, directly or indirectly, disclose information to any third party in connection with a possible Competing Proposal or Major Transaction other than to the extent required to comply with Rule 20.2 of the City Code;

Page 14

(c) except in circumstances consistent with the proviso in clause 8.5(a), or as required by the City Code, it shall not, and shall procure that no Intec Connected Person shall, enter into or participate in any discussions or negotiations or otherwise communicate with any person in relation to any possible Competing Proposal or Major Transaction;

(d) it shall notify Bidco in writing if it or any Intec Connected Person receives any bona fide approach in relation to a possible Competing Proposal or Major Transaction or any valid request for information under Rule 20.2 of the City Code, in each case as soon as reasonably practicable after any such approach or request (as the case may be) is received (provided that it need not identify the third party or the terms of such approach to Bidco); and

(e) it shall, as soon as reasonably practicable thereafter, notify and provide to Bidco any information that it provides to a third party in connection with any possible Competing Proposal or Major Transaction.

8.6 In the event that Intec or any Intec Connected Person receives any Rule 20.2 request as is referred to in clause 8.5 it shall, in complying with such request, provide only such information (and in the same form) as it has previously provided to Bidco and only to the extent that such information has been requested.

9. BREAK FEE

9.1 As an inducement to Bidco to release the Rule 2.5 Announcement, Intec undertakes to pay to Bidco the sum of £2,329,025 (the Break Fee), by way of compensation, if the Rule 2.5 Announcement is released and after such announcement any of the following events occur:

(a) the Intec Directors (or any committee thereof) withdraw, qualify or adversely modify, for whatever reason, the terms of their recommendation of the Acquisition and/or their publicly stated intention to make such recommendation and/or recommend a Competing Proposal; or

(b) a Competing Proposal is announced (whether or not on a pre-conditional basis and whether pursuant to Rule 2.4 of the City Code, Rule 2.5 of the City Code or otherwise) before the Acquisition has lapsed or (with the consent of the Panel) has been withdrawn, and that Competing Proposal or any other Competing Proposal that is announced (whether or not on a pre-conditional basis and whether pursuant to Rule 2.4 of the City Code, Rule 2.5 of the City Code or otherwise) during the same offer period (as such term is defined in the City Code) as the first Competing Proposal subsequently becomes effective, becomes or is declared unconditional in all respects or is otherwise completed; or

(c) if the Acquisition is proceeding by way of the Scheme, the Court Meeting and/or the General Meeting is adjourned without the prior written consent of Bidco (unless such adjournment is a Permitted Adjournment).

9.2 If the Break Fee becomes payable pursuant to clause 9.1, Intec shall pay the Break Fee by not later than five Business Days after the earlier of: (i) the date on which the relevant Competing Proposal becomes effective, becomes or is declared unconditional in all respects or is otherwise completed; or (ii) the time at which Bidco’s original offer lapses or is withdrawn or (if Bidco’s offer is implemented by way of scheme of arrangement) where the Scheme is adjourned sine die.

Page 15

9.3 All sums payable under this clause 9 shall be paid in the form of an electronic funds transfer for same day value to such bank account as may be notified by Bidco in writing to Intec and shall be paid in full free from any deduction or withholding whatsoever (save only as may be required by law) and without regard to any lien, right of set-off, counterclaim or otherwise.

9.4 The parties anticipate, and shall use all reasonable endeavours to secure, that the Break Fee is not treated for VAT purposes as consideration for a taxable supply. If, however, the Break Fee is determined by HM Revenue & Customs to be in whole or part consideration for a taxable supply in respect of which Bidco (or the representative member of the group of which Bidco is a member) is liable to account for VAT then, to the extent that such VAT is recoverable by Intec (or the representative member of the group of which Intec is a member) by repayment or credit, the amount of the Break Fee shall be increased to take account of such recoverable VAT, such that (i) the Break Fee (inclusive of any amount of VAT); less (ii) any amount of VAT in respect of which Intec (or such representative member) is entitled to credit or repayment, shall be equal to the amount that the Break Fee would have been in the absence of any such VAT. For the avoidance of doubt, if and to the extent that such VAT is irrecoverable by Intec (or such representative member) then no additional amount shall be paid in respect of such VAT and the Break Fee shall be VAT inclusive.

9.5 Such adjusting payment as may be required by Intec to give effect to clause 9.4 above shall be made five Business Days after the date on which the determination by HM Revenue & Customs has been communicated by Bidco to Intec (together with such evidence of it as is reasonable in the circumstances to provide, and together with the provision of a valid VAT invoice) or, if later, five Business Days after the VAT is recovered.

9.6 Nothing in this Agreement shall oblige Intec to pay to Bidco any amount (whether in the form of the Break Fee or in damages in respect of any breach of any provision of this Agreement) that the Panel would not permit it to pay pursuant to Rule 21.2 of the City Code or which would otherwise be unlawful.

10. TERMINATION

10.1 This Agreement may be terminated and, subject to clause 10.2, all obligations of Bidco and Intec under this Agreement shall cease, as follows:

(a) as agreed in writing between Bidco and Intec at any time prior to the Acquisition Effective Date;

(b) if the Scheme lapses or terminates, unless Bidco has elected prior to such time or elects within five Business Days following such time, to implement the Acquisition by way of the Takeover Offer in accordance with clause 3.7;

(c) if Bidco elects to implement the Acquisition by way of the Takeover Offer, the Takeover Offer is withdrawn by Bidco (with the consent of the Panel if required) or lapses;

(d) upon service of a notice by Bidco on Intec if at any time prior to satisfaction of the Conditions a person (or persons) not acting in concert with Bidco unconditionally acquires more than 50 per cent. of Intec’s then issued ordinary share capital;

(e) upon service of a written notice by Bidco on Intec if the recommendation of the Intec Directors contained in the Rule 2.5 Announcement is withdrawn, qualified or adversely modified at any time prior to the Scheme Court Hearing; or

Page 16

(f) upon service of a written notice by Intec on Bidco if, to comply with their fiduciary duties (based on appropriate external financial and legal advice), the recommendation of the Intec Directors contained in the Rule 2.5 Announcement is withdrawn, qualified or modified adversely at any time prior to the Scheme Court Hearing; or

(g) if the Acquisition Effective Date has not occurred by the Longstop Date.

10.2 Termination of this Agreement shall be without prejudice to the rights of either of the parties which have arisen prior to termination, including (without limitation) any claim in respect of a breach of this Agreement. Clauses 1 (Definitions and Interpretation), 9 (Break Fee), 11 (Costs), 12 (Announcements), 14 (Entire Agreement) and 15 (Miscellaneous) shall survive termination of this Agreement.

11. COSTS

11.1 Without prejudice to its other rights pursuant to this Agreement (or in relation to a breach by either party of the terms of this Agreement), each party shall pay its own costs and expenses in connection with or incidental to the Acquisition.

12. FIDUCIARY DUTIES OF THE INTEC DIRECTORS

12.1 The obligations and restrictions imposed on Intec and the Intec Directors under clauses 2.1, 2.2, 3.1, 3.2 (a) to (e) (inclusive), 3.2 (h) to (l) (inclusive) and 8.1(d)(vii) of this Agreement shall not apply to the extent that the Intec Directors conclude (based on appropriate external financial and legal advice) that they are obliged to disregard such obligation or restriction in order to comply with their fiduciary duties.

13. ANNOUNCEMENTS

13.1 Subject to clause 13.2, prior to the satisfaction or waiver (as the case may be) of the Conditions, no announcement or statement shall be made regarding the Acquisition except on a joint basis or on terms agreed in advance by the other party (such agreement not to be unreasonably withheld or delayed).

13.2 The restriction in clause 13.1 shall not apply to: (i) any announcement or statement required by applicable law, regulation, court order, Relevant Authority or the rules of any stock exchange provided that the party required to make such an announcement or statement will, if practicable, consult with the other party as to the content and timing of such announcement or statement and the extent of the required disclosure; (ii) any announcement or statement made by either party following an announcement or statement by a third party of a possible offer, or firm intention to make an offer, for Intec; or (iii) any announcement or statement made by Intec in which the recommendation of the Intec Directors is withdrawn, modified, qualified or amended in accordance with clause 6.2.

14. ENTIRE AGREEMENT

14.1 Subject to clause 14.3, this Agreement and the Confidentiality Agreement constitute the entire agreement between the parties relating to the Acquisition and supersede any previous agreement whether written or oral between the parties in relation to the Acquisition, except that the confidentiality provisions in the Confidentiality Agreement shall remain in full force and effect in accordance with the terms of such agreement.

Page 17

14.2 Each party acknowledges that in entering into this Agreement it is not relying upon any pre-contractual statement that is not set out in this Agreement or the Confidentiality Agreement. If there is any inconsistency between the terms of the Confidentiality Agreement and this Agreement, the relevant terms of this Agreement shall prevail.

14.3 The parties agree that the undertakings and obligations set out in paragraph 10 (“Standstill Obligation”) of the Confidentiality Agreement shall expire on the execution of this Agreement. All other terms of the Confidentiality Agreement shall continue in full force and effect, as amended by this clause 14. For the purposes of paragraph 1 (“Duty of Confidentiality”) of the Confidentiality Agreement, Intec hereby consents to the disclosure, copying, reproduction and distribution by CSG International to any provider or potential provider of finance to the CSG Group for the purposes of the Acquisition of any Information reasonably requested by any such provider or potential provider of such finance provided that.

(a) CSG International shall be responsible for procuring that each provider or potential provider of finance who receives Information adheres to the confidentiality obligations contained in the Confidentiality Agreement as if it were a party to such agreement; and

(b) access to Information is provided on the condition that any Information provided to such provider or potential provider of finance is used only for the purposes of making a decision relating to the financing of the Acquisition.

14.4 The parties agree that, on execution of this Agreement, the Non-Solicitation Agreement shall terminate and all rights and obligations of CSG International and Intec thereafter shall cease (save in respect of any antecedent breach of such agreement).

14.5 Except in the case of fraud, no party shall have any right of action against any other party to this Agreement arising out of or in connection with any pre-contractual statement except to the extent that it is repeated in this Agreement or the Confidentiality Agreement.

14.6 For the purposes of this clause, pre-contractual statement means any draft, agreement, undertaking, representation, warranty, promise, assurance or arrangement of any nature whatsoever, whether or not in writing, relating to the subject matter of this Agreement or the Confidentiality Agreement made or given by any person at any time prior to the date of this Agreement.

SCHEDULE 3

INTEC SHARE SCHEMES

Part 1

Share Scheme Proposals

Introduction

1. It is the commercial intention of Intec and Bidco that the options and awards held under the Intec Share Schemes by employees of Intec and its Group will be dealt with in accordance with the terms set out in this Schedule. For the avoidance of doubt, should the Acquisition proceed by way of a Takeover Offer (rather than by way of Scheme), unless otherwise specified the provisions of this Schedule shall apply as far as possible on the same terms and conditions to such Takeover Offer (as applicable).

2. In this Schedule “Intec Share Schemes” means:

(a) the Intec Company Share Option Scheme (the “CSOP”) which provides for the grant of HM Revenue & Customs approved options (the “Approved Options”) and unapproved options (the “Unapproved Options”);

(b) the Intec Long Term Incentive Plan (the “LTIP”) which provides for the grant of performance and matching conditional share awards and options (the “Awards”); and

(c) the Intec 2000 Stock Option and Incentive Plan for United States Employees (the “US Plan”) which provides for the grant of qualifying and non-qualifying incentive stock options (the “US Options”).

3. Intec hereby confirms that:

(a) the table set out in Section A of Part 2 of this Schedule correctly details all subsisting Approved Options, Unapproved Options and US Options to acquire Intec Shares as at the date of this Agreement (together the “Options”);

(b) the table set out in Section D of Part 2 of this Schedule correctly details all subsisting Awards to acquire Intec Shares as at the date of this Agreement;

(c) no further Options or Awards or other rights to acquire Intec Shares will be granted under any of the Intec Share Schemes or any other employee benefit, bonus or profit sharing scheme prior to the effective date of the Scheme; and

(d) save to the extent that certain Options and/or Awards are satisfied using Intec Shares from the EBT (for which see paragraphs 16-18 below), all Options and Awards that are exercised or will vest as a result of the Scheme will be satisfied using new issue Intec Shares.

Making the Proposals

4. If the Acquisition proceeds by way of Scheme, Intec undertakes to take all necessary steps to prepare, in a form to be agreed between Intec and Bidco, letters to each of the participants in the Intec Share Schemes, and to post or arrange the posting of such letters on

Page 23

or as soon as reasonably practicable after the posting of the Scheme Document. Such letters shall be produced in sufficient time to afford Bidco and its relevant professional advisors to comment on the same and shall include a form enabling the participants to exercise their Options conditionally upon the Court sanctioning the Scheme (at the Scheme Court Hearing and to the extent exercisable in accordance with the relevant Intec Share Scheme rules, as amended where applicable and subject to tax authority approval where applicable) and shall inform participants of their rights under the Intec Share Schemes, including details of the lapse provisions in relation to their Options and/or their Awards and explaining what shall happen, under the Scheme, to the Intec Shares that they shall receive on the exercise of their Options and/or the vesting of their Awards (as applicable).

The Proposals: Options

5. Intec hereby confirms that the table set out in Section B of Part 2 of this Schedule correctly details (as at the date of this Agreement) all subsisting Options to acquire Intec Shares that are ‘in the money’ (i.e. their exercise prices are lower than the proposed offer price of 72 pence per Intec Share).

6. For the above purposes, Intec’s remuneration committee (the “Remuneration Committee”) has confirmed that the performance conditions attaching to the subsisting Options set out in Section B of Part 2 of this Schedule have been satisfied in full and the Options are currently exercisable in full in accordance with their terms.

7. Where permitted by the rules of the relevant Intec Share Scheme, holders of subsisting Options shall be permitted to exercise their subsisting Options at such time as would:

(a) enable the holders of Approved Options to qualify, where possible, for beneficial income tax and National Insurance contributions treatment on exercise of such options; and

(b) enable Intec (or the relevant employing company in Intec’s Group) to receive a corporation tax deduction under Part 12 of the Corporation Tax Act 2009 in relation to the exercise of Options and/or receipt of Intec Shares under the Intec Share Schemes;

8. Participants under the CSOP and the US Plan will be offered the opportunity to exercise their Options conditionally upon the Court sanctioning the Scheme (at the Scheme Court Hearing) and shall be offered a ‘cashless exercise facility’ (structured as an undertaking to pay) whereby any exercise price payable on the exercise of an Option (along with any tax, employee and employer’s National Insurance contributions that they have agreed to pay or their equivalents in any jurisdiction required to be withheld) will be deducted from the cash consideration due to the participant under the Scheme and remitted to or at the direction of Intec.

9. Options granted under the CSOP shall lapse, to the extent not exercised, at the end of one month following the effective date of the Scheme. Options granted under the US Plan, to the extent not exercised, will continue to subsist following the effective date of the Scheme, on an indefinite basis and otherwise in accordance with the US Plan rules.

Page 24

The Proposals: Awards

10. The parties agree that the table set out in Section D of Part 2 of this Schedule correctly details (as at the date of this Agreement) all subsisting Awards to acquire Intec Shares that will vest (in the case of conditional share awards) or that will become exercisable (in the case of nil or nominal cost options) upon the Court sanctioning of the Scheme (at the Scheme Court Hearing) subject to the satisfaction of performance conditions.

11. For the above purposes, the Remuneration Committee has confirmed that the performance conditions attaching to the subsisting Awards set out in Section D of Part 2 of this Schedule have been met as to the estimated vesting percentages set out in column 7. These percentages relate to (i) a performance target based on Intec’s earnings per share (“EPS”) and (ii) a performance target based on Intec’s total shareholder return (“TSR”). The Remuneration Committee has further confirmed that Intec’s relative performance against the EPS target has been measured based on an earnings forecast prepared for the Remuneration Committee immediately prior to the announcement of the Acquisition, the results of which are reflected in the estimated percentages and share numbers in Section D of Part 2, accordingly. It has also been confirmed that Intec’s relative performance against the TSR target has been estimated for the purposes of this agreement (the results of which are reflected in Section D of Part 2) but will be measured again as close to the date of delisting as practicable and it is then that the estimated percentages and share numbers in Section D of Part 2 will be finalised. The Remuneration Committee has also exercised its discretion under the Rules of the LTIP by which it has considered it inappropriate to apply the time pro-rata reduction which would otherwise apply to the outstanding LTIP awards.

12. Participants under the LTIP whose Awards are in the form of nominal cost options and which will become exercisable upon the Court sanctioning of the Scheme will not be required to finance the exercise of such Awards. Instead the Participants will be offered the opportunity to exercise their Awards using a ‘cashless exercise facility’ on the same terms as the Options described in paragraph 8 above with the exercise price to be deducted from the cash consideration due to them under the Scheme and remitted to or at the direction of Intec.

13. Awards will lapse, to the extent not exercised in the case of nil or nominal cost options and to the extent not vested in the case of conditional share awards, in accordance with the LTIP rules.

The Proposals: Non-UK Jurisdictions

14. The parties agree that they shall co-operate together to consider whether it may be appropriate for tax, securities law or administrative reasons to invite holders of Options and/or Awards who are resident in a jurisdiction outside of the UK, as an alternative to exercise and/or vesting, to cancel their Options and/or Awards conditionally upon the Scheme becoming effective, in consideration for a cash payment equal to the offer price of 72 pence per Intec Share less any applicable exercise price per Intec Share, multiplied by the number of Intec Shares subject to the relevant Option / Award (the “Cash Cancellation Payment”). Any such Cash Cancellation Payment will be made by Bidco (unless otherwise agreed between Intec and Bidco) and will be subject to a deduction for any applicable withholding taxes and employee social security contributions due.

The Underwater Options

15. Intec hereby confirms that the table set out in Section C of Part 2 of this Schedule correctly details (as at the date of this Agreement) all subsisting Options to acquire Intec Shares that are ‘underwater’ (i.e. their exercise prices are higher than the proposed offer price of 72 pence per Intec Share).

Page 25

The EBT

16. The Intec Employee Share Trust, constituted by a trust deed dated 13 June 2000 (the “EBT”), currently holds 270,000 unallocated Intec Shares in the trust fund.

17. The parties agree that the trustees of the EBT will be requested to consider and if thought fit, agree to satisfy certain Options and/or Awards using these unallocated Intec Shares.

18. To the extent that the trustees of the EBT are unable to utilise any or all of the Intec Shares held by the EBT to satisfy Options and/or Awards, any remaining proceeds received for the Intec Shares held by the EBT under the Scheme will be used by the EBT to repay the loan currently outstanding between by the EBT and Independent Technologies Systems Limited (a subsidiary of Intec) which loan was provided on an interest free basis under the terms of a loan agreement dated 14 June 2000.

Articles of Association

19. Intec and Bidco agree that the board of directors of Intec shall propose (at the General Meeting) an amendment to the articles of association of Intec by the adoption and inclusion of a new article under which any Intec Shares issued after the effective date of the Scheme shall be immediately transferred to Bidco (or as it may direct) in exchange for the same consideration as is due under the Scheme.
