EXHIBIT 10.1 The Directors Thermodynetics Inc 651 Day Hill Road Windsor CT 06095-1714 USA 10 March 2006 Dear Sirs, APPOINTMENT OF DAWNAY DAY 1.

DDCF and DDT are together referred to herein and in the attached standard terms as "Dawnay, Day". 1.2 Thermodynetics Inc ("Thermodynetics" or "the Client") is a US publicly traded company based in Windsor, Connecticut, USA. Thermodynetics, through its subsidiary, Turbotec Products Inc ("Turbotec"), is a manufacturer of high performance, high quality heat exchangers, fabricated metal components and flexible connector products for heat transfer, transportation, and plumbing applications. Turbotec markets its products in the United States, Canada and abroad to customers in the space conditioning, refrigeration, automotive, biomedical, plumbing, appliance, water heating and aerospace industries. 1.3 It is proposed that the Client will establish a UK registered Public Limited Company ("Newco") which is expected to change its name to Turbotec Products PLC (or such other name as the Client may approve) which will subsequently acquire the whole of the common stock of Turbotec held by the Client in exchange for the issue to the Client of ordinary shares in Newco. As a result, Newco will become a wholly-owned subsidiary of the Client. 1.4 It is proposed that Newco's ordinary shares are admitted to trading ("Admission") on AIM, a market operated by London Stock Exchange PLC ("LSE") in conjunction with a share placing ("the Placing") under which: 1.4.1 approximately $3.5M (net of expenses) will be raised as capital for Newco's trading subsidiary, Turbotec, through the issue of new ordinary shares in Newco; and 1.4.2 approximately $3.5M (net of expenses) will be raised as capital for the Client through the sale of ordinary shares held by it in Newco. 1.5 The proposed Placing and Admission are herein together referred to as the "Transaction". 1.6 Dawnay, Day has agreed to use its reasonable endeavours to procure investors for the new and existing ordinary shares in Newco which are to be issued and sold under the Placing. 1.7 Following the Transaction it is envisaged that the Client will retain a shareholding of approximately 60 per cent of the then issued share capital of Newco. 1.8 Dawnay, Day has also agreed with the Client that, on and from Admission, it will act as Newco's Nominated Adviser and Broker. 2.

The scope of the Nominated Adviser's role is broad and may involve Specific Assignments from time to time. Any matter which absorbs more than 2 days shall be treated as a Specific Assignment; 2.1.11 advising Newco on compliance with the City Code on Takeovers and Mergers and Substantial Acquisition Rules and liaising with the Takeover Panel as DDCF deems appropriate; 2.1.12 liaising with the LSE and regulatory bodies as required. 2.2 DDT WILL, ON AND FROM ADMISSION, ACT AS BROKER TO NEWCO AND AS SUCH ITS ROLE PRIOR TO AND FOLLOWING ADMISSION WILL INCLUDE: 2.2.1 advising the Client in relation to proposals to raise capital for Newco through the issue of new ordinary shares (and/or other securities) under the Placing; 2.2.2 advising the Client in relation to proposals to raise capital for the Client through the sale of existing ordinary shares (and/or other securities) under the Placing; 2.2.3 assisting with the preparation of a presentation for investors in relation to Newco and Turbotec; 2.2.4 preparing any pre-marketing research documentation; 2.2.5 coordinating and arranging the marketing to investors of the issue and sale of ordinary shares (and/or other securities) in Newco; 2.2.6 coordinating and arranging the Placing/underwriting arrangements, including, the receipt of funds by the Client and Newco, dealing arrangements, settlement registration and the payment of certain agreed expenses on behalf of the Client and Newco; 2.2.7 following Admission, as Newco's Broker, maintaining regular contact with Newco identifying any significant or unusual movements in its share price and identifying, as requested or required and as available to DDT, trading in Newco's ordinary shares and providing, when appropriate, data and statistics on share price movements and trading volumes; 2.2.8 preparing analysts' reports on Newco at such intervals as are deemed appropriate (after consultation with Newco's management); 2.2.9 providing twice yearly analyses of Newco's share registers; 2.2.10 providing guidance to Newco on its management of market expectations; 2.2.11 when appropriate and when requested, arranging for the management of Newco to make presentations to institutional investors and advising on the form and content of such presentations. 2.3 FOLLOWING ADMISSION, DAWNAY, DAY WILL: 2.3.1 if requested (and on reasonable notice), attend board meetings, annual general meetings and extraordinary general meetings of Newco; and 2.3.2 provide such other advice and assistance as may be required by the board of Newco and agreed with Dawnay, Day as would normally be provided by a nominated adviser, financial adviser and broker of a company whose securities are traded on AIM. 2.4 Dawnay, Day will work in conjunction with, and on occasions Dawnay, Day may need to rely on work performed by, Newco (and, where appropriate, by the Client) and Newco's other advisers. The scope of the services provided by Dawnay, Day and its responsibilities in providing them will be restricted to those usually provided and assumed by a company's nominated adviser or broker. In particular, Dawnay, Day would not expect to advise on the commercial aspects of any particular transaction, neither will we advise on legal, taxation or accounting issues, or in any other areas which are outside our expertise. 2.5 For the avoidance of doubt it is agreed that Dawnay, Day's responsibilities in relation to the Transaction and following Admission will not include verifying any advice (whether verbal or written) provided to us by the professional parties including solicitors and accountants retained by the Client and Newco. Dawnay, Day shall, however, be entitled to rely on this advice in performing its services. 2.6 For the avoidance of doubt, it is agreed that Dawnay, Day is not accepting responsibility for the commercial assessment of the Transaction or any other activities of the Client and/or Newco, such responsibility being entirely that of the Client's directors. 2.7 For the avoidance of doubt, it is agreed that Dawnay, Day is not obliged to sell, acquire, place, underwrite or sub-underwrite any investments, or to lend monies, unless and until it is otherwise expressly so agreed in writing. 2.8 Dawnay, Day may make unsolicited communications with the Client and Newco in connection with the performance of its services under this Agreement. 2.9 In carrying on its corporate finance and broking business Dawnay, Day is subject not only to the general laws that apply to such business, but also to a number of rules and regulations and the requirements of a number of regulators, many of which may also apply directly to Newco. Particular examples are the rules and regulations of the LSE, the Panel on Takeovers and Mergers, the Financial Services Authority ("FSA") and the Bank of England. The Client agrees that Dawnay, Day's duties to the Client and Newco will not restrict Dawnay, Day's freedom to take all steps that it considers to be necessary to comply with the laws, rules and regulations applicable to it and to refuse to take steps which it does not consider to be compliant, even if its action in so doing would apart from the provisions of this paragraph conflict with the terms of this Agreement. 2.10 In order to assist in carrying out its services under this Agreement Dawnay, Day shall be entitled but not obliged to appoint legal and other advisers or sub-agents as it deems reasonably necessary, the cost of which will be borne by the Client and/or Newco but such costs will be agreed with the Client before the costs are incurred and Dawnay, Day will inform the Client on a timely basis as to the costs incurred. For the avoidance of doubt, Dawnay, Day confirms its intention to appoint legal advisers to advise it in connection with the Transaction. 3. DAWNAY, DAY'S REMUNERATION 3.1 The Client agrees that Dawnay, Day shall be paid a fixed, non-refundable fee of (pound)20,000 to be paid on a staged basis (the "STAGED FEE") as follows: (pound)10,000 to be paid at the time when this Agreement is signed, (pound)5,000 to be paid one month thereafter and a further (pound)5,000 to be paid two weeks thereafter. 3.2 The Client also agrees that, on Admission, Dawnay, Day will be entitled to be paid out of the proceeds of issue and sale of ordinary shares in Newco pursuant to the Placing : 3.2.1 a commission equal to 6 PER CENT. of the monies raised by the Placing of new ordinary shares in Newco; and 3.2.2 a further fee of (pound)100,000. 3.3 in the event Newco's ordinary shares are not admitted to trading on AIM for any reason, Dawnay, Day shall not be entitled to any fees other than the Staged Fee and out-of-pocket expenses reasonably and properly incurred by Dawnay, Day. 3.4 The Client also agrees that, on Admission, it shall pay Dawnay, Day a commission equal to 6 PER CENT. of the monies raised by the sale of existing ordinary shares in Newco held by the Client pursuant to the Placing. 3.5 VAT, if applicable, will be charged on any fees and costs invoiced. 3.6 Following Admission and subject to agreement of the terms of Nominated Adviser and Broker Agreements, Dawnay, Day will be due an annual retainer of (pound)40,000 for acting as Nominated Adviser and Broker to Newco payable quarterly in advance with the first quarterly payment due on the date of Admission. Dawnay, Day will also be paid further fees for Specific Assignments to be agreed with the Client at the relevant time. 3.7 Should any transactions proceed other than the Transaction as contemplated in this Agreement and should Dawnay, Day have contributed directly or indirectly to that/those transaction(s), then Dawnay, Day shall be paid fees commensurate with its advice and/or other involvement. 3.8 Should the Transaction become more protracted, or more complex than initially contemplated, Dawnay, Day reserves the right to bill further amounts on account and/or charge additional fees to those set out above on a basis to be agreed. In particular, the above fees are on the basis that Admission takes place by no later than 30 September 2006; 3.9 Fees and expenses payable to Dawnay, Day pursuant to paragraphs 3.2 and 3.4 above may be deducted from the proceeds of the issue and sale of ordinary shares in Newco pursuant to the Placing,. Subject thereto all fees and expenses shall be paid within 10 days of the relevant invoice. 4. EXPENSES 4.1 Any out-of-pocket expenses (including hotel accommodation and travel expenses) reasonably and properly incurred by Dawnay, Day in relation to its role as described above shall be for the Client's account. Dawnay, Day shall not incur out-of-pocket expenses in excess of (pound)3,000 in any three month period without the Client's prior approval. Such costs/expenses will be recoverable by Dawnay, Day from the Client whether or not any transaction is completed. It is agreed that, on Admission, Dawnay, Day may recover costs and expenses incurred from the the proceeds of the issue and sale of ordinary shares in Newco pursuant to the Placing. 4.2 The Client will pay the reasonable and properly incurred expenses of the lawyers acting on behalf of Dawnay, Day in connection with the Transaction as described above. An estimate of such expenses in connection with the Transaction will be provided to the Client for approval prior to Dawnay, Day engaging lawyers for this purpose and any actual or foreseeable variation in any legal fee quotation will be notified to the Client on a timely basis. For the avoidance of doubt, the Client will pay such reasonable and properly incurred legal expenses regardless of whether the Transaction proceeds and Dawnay, Day will inform the Client and Newco on a timely basis as to the costs incurred. Any payment in respect of such legal fees will not be regarded as a reduction in the fees payable pursuant to the monthly transaction retainer fees described above. It is agreed that, on Admission, Dawnay, Day may recover the expenses of its lawyers from the proceeds of the issue and sale of ordinary shares in Newco pursuant to the Placing. 5. RESPONSIBILITY AND ANNOUNCEMENTS 5.1 The Client's directors acknowledge that they are the persons responsible for information provided to Dawnay, Day and for the published documentation and that they will be required to sign responsibility statements in relation thereto. For the avoidance of doubt the scope of this Agreement specifically excludes any commitment or responsibility on the part of Dawnay, Day to conduct any verification or due diligence work and you should therefore not rely on Dawnay, Day to carry out verification or seek, identify or assess due diligence matters. 5.2 Immediately prior to and following Admission, Dawnay, Day may release announcements on Newco's behalf, subject to the approval of a duly authorised director of Newco. Newco's directors recognise that, while Dawnay, Day may advise on the drafting of announcements, it is Newco's directors who are the persons responsible for them. Where there are circumstances where the release of announcements brings Dawnay, Day within the scope of the Market Abuse regime (even though there may be no intention to commit market abuse), Dawnay, Day may decline to act as release agent for Newco. 5.3 The Client agrees that, subsequent to completion of the Transaction, Dawnay, Day will have the right to publish advertisements in financial and other newspapers and journals at Dawnay, Day's expense describing its services in connection solely with the Transaction, the contents of which advertisements will be subject to the Client's prior approval (such approval not to be unreasonably withheld or delayed). 6.

Because of potential conflicts of interest and to preserve confidentiality of customer information, the Dawnay, Day Group operates rules and procedures (commonly known as "Chinese Walls") to ensure the confidentiality of information. 3.2 You acknowledge and agree provided we maintain all information provided by or with respect to you or your business as confidential that we may provide our services to you: (i) notwithstanding that another connected company or division/part of DDCF or DDT (or a customer of such a company) might be regarded as having interests which conflict with our mandate with you (including but not limited to effecting transactions or holding positions for its own account or those of customers in securities or related investments which are the subject of or related to or affected by the Mandate); AND (ii) only on the basis of information known to the personnel within DDCF or DDT who are responsible for advising you; AND (iii) without being required or obliged to have any regard to any other information within the Dawnay, Day Group; AND (iv) without being required to disclose to you or the employees advising you nor to make use for your benefit any information known to Dawnay, Day that belongs to or is confidential to another client or to another member of the Dawnay, Day Group or that belongs to and is confidential to DDCF or DDT and relates to some other aspect of its business. 3.3 If we become aware that we, a connected company, or any director or employee has any interest in any proposed transaction which may conflict to a material extent with the Mandate, then we will, as soon as practicable either: (i) disclose that such a conflict has arisen; OR if such disclosure would, in our reasonable opinion, be contrary to our obligations to a third party or otherwise be unethical, (ii) cease to provide services to you; OR (iii) take other steps as we reasonably consider to be fair and reasonable in the circumstances. Dawnay, Day's directors and employees are also required to comply with a "Policy of Independence" and to disregard any such interest, relationship or arrangement when advising you or arranging transactions for you. 4. LIMITATION ON DAWNAY, DAY'S DUTIES 4.1 Save to the extent (if any) expressly agreed in writing with you, we shall not have any obligation or other responsibility to carry out any financial or other investigation or due diligence into any corporate or other entity which is involved in or relevant to the Mandate including, without limitation, any prospective target or investee company or prospective purchaser. 4.2 Dawnay, Day accepts no liability or other responsibility to you if, in the course of the performance of our duties to you, we reveal to a prospective financier or other third party the existence of a potential transaction or other business opportunity and such financier or third party (or connected parties) subsequently pursues and/or secures such transaction or other opportunity. 4.3 Dawnay, Day has no duties or obligations to you other than those expressly and specifically set out in the terms of the Mandate and in other written correspondence with you. Dawnay, Day shall not be liable to you except in respect of its negligence or wilful default in the performance of such duties and obligations and you shall make no claim against Dawnay, Day or any of its directors, officers, members, employees or agents ("Indemnified Persons") to recover any loss or damage which you may suffer by reason of or arising out of anything done or omitted to be done in relation to the provision of services by Dawnay, Day unless and to the extent that such claim is made against Dawnay, Day alone and arises as a result of its negligence or wilful default in the performance of such duties and obligations. 4.4 However, these provisions shall not exclude or restrict any duty or liability which we have in relation to you under the rules of FSA or any liability which we may incur under the Financial Services and Markets Act 2000 ("FSMA") or those rules in respect of breach of any such duty. 5. CUSTOMER INDEMNITY 5.1 You hereby irrevocably and unconditionally agree to indemnify and hold harmless each of DDT and DDCF , for itself and as trustee for each of the other Indemnified Persons (as defined in paragraph 4.3 above) and any connected company and the directors and employees of any connected company, (whether before or after 2 of 2 termination of the Mandate) from and against any and all claims, actions, demands, liabilities, proceedings or judgements brought or made against us and all losses, charges and expenses (including but not limited to fees and expenses incurred in connection with the investigation, preparation for or defence of any inquiry, inspection or investigation or any pending or threatened claim, action, litigation or proceedings) which any of us may suffer or incur and which in any case are directly or indirectly occasioned by or as a result from or are attributable to anything done or omitted to be done in connection with the provision of services to you by us, or any act or omission (including without limitation, the provision of information which is inaccurate or misleading) by you. 5.2 However, this indemnity shall not apply to any loss or liability to the extent it arises or results from any contravention by us of the rules of the FSA or of the FSMA or from any negligence or wilful default on our part. 5.3 References in this section to "us" or "our" include references to Dawnay, Day, and each of the other Indemnified Persons (as defined in paragraph 4.3 above) and any connected company and the directors and employees of any connected company. 6. AUTHORISATION 6.1 Dawnay, Day is authorised by you to do anything on your behalf that Dawnay, Day in its absolute discretion considers necessary or desirable in order (i) to carry out the Mandate which may include acting through approved agents or sub-agents and (ii) to comply with any applicable legal or regulatory requirements. 6.2 You authorise Dawnay, Day to rely on any instructions, notices or requests (whether in writing or not) given (or appearing to be given) by any director or employee of yours who is reasonably believed by Dawnay, Day to be authorised by you to give such instructions, notices or requests. 7. FSA CLIENT MONEY 7.1 Dawnay, Day does not hold Client Money and is therefore not authorised to and shall not hold or receive monies on your behalf. 7.2 The Customer will arrange for an account or accounts to be established with one or more approved banks in order for monies to be held or received in relation to the Transaction or any other transaction contemplated by the Mandate. 8. GENERAL PROVISIONS 8.1 The basis of our charges is as set out in the Mandate Agreement. 8.2 You undertake to comply with and abide by all applicable statutes, rules, regulations and requirements, including without limitation the City Code on Take-overs and Mergers. 8.3 The Mandate Agreement, when countersigned, and these standard terms represent our contract with you. No person who is not a party to this contract shall have any right to enforce any terms of it, whether or not any of the terms expressly (or by implication) purport to confer any benefit on such persons. You will not pursue any claims against Dawnay, Day's employees or persons engaged by Dawnay, Day under a contract for services personally and acknowledge that such persons are entitled to rely on the Contracts (Rights of Third Parties) Act as a means of preventing such claims being brought against them. 8.5 You agree that: (i) Dawnay, Day may require confirmation or evidence to support information contained in, or omitted from, any document Dawnay, Day is required to approve, or in respect of which you may incur any liability to third parties, whether or not you accept full responsibility for the preparation and contents of the document; (ii) Dawnay, Day may refuse to issue, consent to the issue of, or approve any document, or require you to cease to distribute any document, if at any time Dawnay, Day becomes aware of information that in its opinion renders the document untrue, inaccurate or misleading in any material respect; (iii) without detracting from Dawnay, Day's right to make such enquiries as Dawnay, Day may consider appropriate in the discharge of its obligations hereunder, shall be entitled to rely upon all information supplied by you or your advisers and shall not in any respect be responsible for the accuracy or completeness of, or have any obligation to verify, the same; and (iv) any documents provided to us in final form will be approved by your Board, and your directors will be solely responsible for them. 8.6 Paragraph headings are used in these Terms of Business for convenience only and shall not affect their construction. 3 of 3 9. TERMINATION 9.1 Subject to the specific termination terms set out in the Mandate Agreement: (i) this Mandate can be terminated by either party giving one month's written notice to the other. (ii) if within 12 months of the termination of the Mandate, you enter into any transactions initiated by us or referred to in the Mandate Agreement, you hereby agree to pay us a fee calculated in accordance with the provisions of the Mandate Agreement. 10. COMPLAINTS If you have any complaints about our services under this Mandate, you should write to the "Group Compliance Officer" of Dawnay, Day at 9-11 Grosvenor Gardens, London, SW1W 0BD. The Group Compliance Officer is responsible for investigating and resolving any complaints from Customers. We will provide you with details of our internal Complaints Procedure upon request, or automatically in the event that you make a complaint that is not satisfactorily resolved within one business day after receipt of your complaint. 11. COMPENSATION We are covered by the Financial Services Compensation Scheme. You may be entitled to compensation from the scheme if we cannot meet our obligations. This depends on the nature of the claimant, type of business and the circumstances of the claim. Eligible claimants in respect of most types of investment business are covered for 100% of the first (pound)30,000 and 90% of the next (pound)20,000 so the maximum compensation is (pound)48,000. Further information about compensation arrangements is available from the Financial Services Compensation Scheme. 12. GOVERNING LAW AND JURISDICTION These Terms of Business and the Mandate Agreement shall be construed in accordance with and governed by English Law. You submit to the non-exclusive jurisdiction of the English Courts.
