                                    RECITALS
                                    --------

     A. Pursuant to various  purchase orders and/or supply  contracts  issued by
Benteler  and  accepted  by Vulcan  (collectively,  the  "Purchase  Orders"  and
individually,  a "Purchase  Order"),  Vulcan is  obligated  to  manufacture  and
provide  Benteler with component  parts as set forth in the Purchase Orders (the
"Component  Parts").  Certain  of the  Component  Parts  are made for use in the
Nissan ZV7 product line.

     B. Citizens  provides  certain working capital and term financing to Vulcan
pursuant to a certain Demand Loan and Security Agreement (All Assets) dated July
30,  2003  between  Vulcan  and  Citizens  (together  with all other  documents,
instruments  and agreements  related thereto as same may be amended from time to
time, the "Citizens Loan Documents.")

     C. As of July 6, 2005,  Vulcan and  Thermodynetics  were  indebted to Wells
Fargo in the amount of $1,566,114.87 (the "Wells Fargo Indebtedness"),  pursuant
to a  Promissory  Note and  Security  Agreement  dated  as of July 25,  2003 and
related  documents  (the "Wells Fargo Loan  Documents").  Interest  continues to
accrue and become a part of the Wells Fargo  Indebtedness at the rate of $271.63
per day. The Wells Fargo  Indebtedness  is secured by a first priority  security
interest  in the  equipment  related  to the ZV7 line,  and all other  equipment
financed by Wells Fargo,  which is  described  on the  attached  Schedule 1 (the
"Purchased Equipment").

     D. As of July 6,  2005,  Vulcan  was  indebted  to Sturgis in the amount of
$359,551.39, plus all accrued fees and costs in the amount of $2,500 incurred by
Sturgis   in   connection   with  the   Sturgis   Indebtedness   (the   "Sturgis
Indebtedness"),  pursuant to a loan and  security  agreement  and other  related
documents  (the  "Sturgis  Loan  Documents").  Interest  continues to accrue and
become  a part of the  Sturgis  Indebtedness  at the  rate of  $53.52  per  day.
Thermodynetics has guarantied repayment of the Sturgis Indebtedness.

     E.  Citizens,  Wells  Fargo and  Sturgis  are  parties to an  Intercreditor
Agreement  dated  as of July  31,  2003  (the  "Intercreditor  Agreement").  The
Intercreditor  Agreement  provides that as between the Lenders,  the priority of
security interests in the assets of Vulcan is as follows:

                 Purchased Equipment:        1st - Wells Fargo, 2nd - Sturgis,
                                             3rd - Citizens

                                      (a)


                 All other assets of Vulcan: 1st - Citizens, 2nd - Sturgis

     F.  Vulcan  has  advised  Benteler  that it  faces  certain  financial  and
operational problems that impact on Vulcan's financial viability which threatens
the  supply of  Component  Parts.  As a result,  Benteler  must work  toward the
potential transition of the production of Component Parts, for the ZV7 and other
lines  currently  produced  by Vulcan for  Benteler,  either to  Benteler or its
designee.

     G. In this regard,  Vulcan has  requested  that  Benteler  provide  certain
financial  accommodations  to  Vulcan  in  order  to allow  Vulcan  to  continue
production of Component Parts pursuant to the terms of this Agreement.

     H. Benteler has requested  that Vulcan and Citizens  provide  Benteler with
certain  acknowledgements  and  assurances  in order to ensure an  uninterrupted
supply of  Component  Parts to satisfy  Benteler'  production  requirements  and
resourcing efforts through August 15, 2005.

     I. In  connection  with its  resourcing  efforts,  Benteler has arranged to
purchase the  Purchased  Equipment  from Wells Fargo and certain other assets of
Vulcan, upon surrender of such assets by Vulcan to Wells Fargo or sale by Vulcan
directly to Benteler.

     J.  Subject  to the terms of this  Agreement,  (a)  Benteler  has agreed to
provide certain  financial and other  accommodations  to Vulcan,  (b) Vulcan and
Citizens  have  agreed  to  provide   Benteler  with  certain   assurances   and
acknowledgements  as more  particularly  set  forth  herein,  and (c)  Benteler,
Vulcan, and Thermodynetics  have agreed to Benteler's purchase of certain assets
of Vulcan.

     WHEREFORE,  based upon the  foregoing  recitals  and for good and  valuable
consideration,  the receipt and adequacy of which is  acknowledged,  the parties

     3.  Additional Equipment Purchases by Benteler.

         (a)  Benteler shall advise Vulcan and Citizens on the earlier of August
15, 2005 or within five business  days after it removes the Equipment  described
in sections  (a) and (b),  above,  if it desires to purchase  any  equipment  of
Vulcan in addition to the Equipment  outlined in sections (a) and (b),  above by
making an offer in writing to Vulcan  identifying  the specific  equipment to be
purchased and the proposed price to be paid and  requesting  that Citizens agree
to  release  its  lien  in the  specific  equipment  to be  purchased  for  said
consideration.

         (b)  In the event that Vulcan  accepts such offer,  Vulcan shall notify
Citizens of such and within 10 days thereof  Citizens  shall  inform  Vulcan and
Benteler whether or not Citizens will release its lien in such equipment for the
stated consideration. If an offer is accepted and Citizens has agreed to release
its lien on the equipment,  the purchase  price must be paid by Benteler  within
seven (7) days of  Citizens'  agreement  to release its lien or before  Benteler
removes  any  equipment  purchased  under  this  Section  3 from  the  Premises,
whichever occurs first.

         (c)  In the  event of a  purchase  pursuant  to this  Section  3,  upon
payment of the purchase price agreed to by the parties, (i) Vulcan shall provide
Benteler  with a Bill of Sale for the  equipment,  (ii)  Citizens  shall provide
Benteler  with  a  UCC-3  Financing  Statement  Amendment  which  releases  such
equipment from Citizens'  security  interest,  in form and substance  reasonably
acceptable to Citizens.

     4.  Benteler's Accommodations.

         (a)  In order to induce  Citizens  to provide the  accommodations  more
fully  set  forth  in this  Agreement  and  subject  to  Citizens  being in full
compliance with this  Agreement,  Benteler  agrees,  for the benefit of Citizens
only, to suspend and not to assert any  defenses,  rights and claims for setoffs
and/or recoupment, other than Allowed Setoffs (the "Waived Setoffs") against its
payables  to  Vulcan.  "Allowed  Setoffs"  means (a)  ordinary  course  setoffs,
recoupments  or deductions  for  defective or  non-conforming  product,  quality
problems,  warranty  claims for which Vulcan is liable,  unordered or unreleased
parts returned to Vulcan,  short  shipments,  misshipments,  improper  invoices,
duplicate  payments  or  billing  errors  (collectively,  the  "Ordinary  Course
Offsets"), which Ordinary Course Offsets shall not exceed $19,000, cumulatively,
and (b) the sum of $382,000.

         (b)  Subject to the terms of this  Section,  which is intended  for the
sole benefit of  Citizens,  Benteler  expressly  reserves and DOES NOT waive any
rights and interests it may have against Vulcan,  including setoffs asserted for
defensive  purposes.  However,  Benteler  agrees  that  it  shall  refrain  from
exercising its rights with respect to the Waived Setoffs against its payables to
Vulcan until such time as Vulcan's  obligations  to Citizens  under the Citizens
Loan Documents are satisfied in full.

         (c) Subject only to the Allowed  Offsets and as long as Citizens is in
compliance  with its obligations  under this  Agreement,  Benteler shall pay all
payables  to Vulcan as they come due,  either  within 30 days from the date such
payables  are  invoiced  (but no later than August 5, 2005) or the date on which


                                       4


Benteler removes the Equipment from the Premises, whichever occurs first.

         (d) Benteler  will  purchase all of Vulcan's  raw  materials,  work in
process and finished goods  inventory  related to the Component Parts which were
at the  Premises  as of July 5,  2005  and are  "useable"  (defined  below)  and
"merchantable" (defined below), (the "Inventory") from: Vulcan, and make payment
thereon to Citizens in accordance with the terms of this Agreement. For purposes
of this Agreement,  the term "useable" means Inventory which is not obsolete and
is capable of being used by  Benteler  in  connection  with its  production,  as
determined by Benteler in its sole discretion.  The term  "merchantable" as used
in this Agreement means merchantable as that term is defined in Section 2-314 of
the UCC AND  reasonably  in  conformance  with  all  applicable  Purchase  Order
specifications.

         (e)  The purchase  price for the  Inventory to be purchased  under this
Agreement (the "Inventory  Purchase  Price") will be (A) 100% of the cost of the
raw  materials  incorporated  into the  Inventory,  with cost based on  Vulcan's
actual  cost,   if  the   Inventory   is  in  the  form  of  raw   materials  or
work-in-process, or (B) the Purchase Order price if the Inventory is in the form
of finished Component Parts.

         (f)  Benteler will only be obligated to purchase  Inventory  under this
Agreement  if Vulcan can sell and deliver  the  Inventory  to Benteler  free and
clear of all  liens  and  security  interests.  Upon  payment  of the  Inventory
Purchase Price, Citizens shall release all liens, claims, or encumbrances it has
in the Inventory.

notify him that such payment is being made.  Pursuant to this Agreement,  Vulcan
hereby authorizes and directs Citizens to (i) debit from the appropriate  Vulcan
account any  payments  received  pursuant to this  Section 4 and (ii) apply such
payment to the Citizens  Indebtedness  in such manner as Citizens  determines in
its sole discretion.

     5.  CITIZENS' ACCOMMODATIONS.
         -------------------------

         (a)  In consideration of, and subject to,  Benteler's  performance with
each  and  every of its  obligations  hereunder,  Citizens  shall  refrain  from
enforcing any of its rights against  Vulcan's assets used in connection with the
production of Component  Parts,  so as to interfere with Vulcan's  production of


                                       5


Component Parts for Benteler until the earlier of (i) Benteler's refusal to fund
any Budget or, alternatively, to fund operations at the Premises under an agreed
upon Access Agreement or (ii) August 15, 2005. To the extent Benteler  continues
to fund  operations  and to occupy the Premises  beyond August 15, 2005,  Vulcan
agrees to  negotiate  with  Benteler  in good faith,  pursuant to Section  9(f),
below, as to a fair rental value for Benteler's  continued use of Vulcan assets,
subject to the approval of Citizens,  if any, beyond August 15, 2005. A schedule
of Vulcan  assets to be used by in  connection  with the  production  (either by
Benteler or Vulcan) of Component Parts is attached hereto as Schedule 3.

         (b)   Citizens'  agreement to refrain from  enforcing any of its rights
against  Vulcan's  assets  identified  on  Schedule  3 so as to  interfere  with
Vulcan's  production of Component  Parts for Benteler  pursuant to Section 5(a),
above,  shall not prevent  Citizens  from  exercising  its rights under the loan
documents  with respect to Vulcan assets which are not identified on Schedule 3,
including,  but not  limited  to, the right to  conduct an auction  sale of such
assets. To the extent a Vulcan asset necessary for Vulcan's continued production
of Component  Parts is excluded from Schedule 3, Benteler and Citizens  agree to
work together in good faith to ensure that Citizens' exercise of its rights with
respect to the excluded Vulcan asset does not interfere with Vulcan's production
of Component Parts for Benteler under this Agreement.

         (c)   Benteler  has  advised  Citizens  that  it may  purchase  certain
materials  necessary  for the  production of Component  Parts  directly from the
suppliers  of  such  materials.  Citizens  agrees  that to the  extent  Benteler
purchases any materials directly that all such materials shall be Bailed Assets,
subject to Benteler's  right to remove from the Premises as set forth in Section
7,  below,  and NOT  SUBJECT TO any lien,  claim,  encumbrance  or  interest  of
Citizens.

          (d) The parties to this Agreement  acknowledge  that,  notwithstanding
Benteler's  agreement  to  refrain  from  applying  the Waived  Offsets  against
payables owed by it to Vulcan, as set forth in Section 4, above,  Benteler still
maintains a claim against Vulcan for the Waived Offsets until paid but shall not
at any  time  prior to the  payment  in full of all  obligations  of  Vulcan  to
Citizens, assert any such claim.

     6.  Vulcan's and Thermodynetics Accommodations.

         (a)  For so long as Benteler continues to fund the Budget,  Vulcan will
continue to produce Component Parts, including any Component Parts for inventory
banks,  and comply with the terms of the Budget through the Funding Period,  all
as defined below.

         (b)   Vulcan  will  provide  Benteler  and its  respective  agents  and
representatives,   consultants  and  employees  reasonable  access  to  Vulcan's
operations,  books,  records,  officers and employees at reasonable times during
business hours, or outside of business hours upon  reasonable  request,  for the
purposes of monitoring  Vulcan's compliance with the terms of this Agreement and
any other agreements and contracts between the parties and Vulcan. Vulcan agrees
to fully cooperate with the agents, representatives,  consultants,  officers and
employees of the respective  parties to accomplish the ends contemplated by this
Agreement.

                                       6


         (c) For so long as Benteler continues to fund the Budget,  Vulcan will
build inventory banks of Component Parts in the following amounts:

               (i)  19,000  excess  Component  Parts for the  Nissan ZV7 line by
     August 15, 2005, above and beyond the Component Parts required for Nissan's
     consumption during that period;

               (ii) 12,000 excess  Component  Parts for Toyota by July 31, 2005,
     above and beyond the  Component  Parts  required for  Toyota's  consumption
     during that period;

               (iii) 18,000 excess parts made for CS by July 31, 2005, above and
     beyond the Component Parts required for consumption during that period; and

               (iv) 16,000 excess parts made for the Hemi also by July 31, 2005,
     above and beyond the parts required for consumption during that period.

Vulcan will immediately ship inventory bank Component Parts as they are produced
to such locations designated by Benteler. Benteler shall have the right to waive
any or all of the inventory bank requirements at its discretion.

         (d)  For so long as Benteler continues to fund the Budget,  Vulcan will
allow Benteler,  its employees,  agents,  contingency  suppliers and consultants
access to inspect Bailed Assets and Vulcan's  operations at mutually  convenient
times upon request.

         (e)  Simultaneous  with execution of this Agreement,  Vulcan will enter
into the  Access  Agreement  attached  as  Exhibit H (the  "Access  Agreement"),
discussed more fully in Section 9, below.

         (f)  Vulcan  agrees to provide to Benteler (i) periodic  cashflows  and
comparisons to the Budget on a weekly basis; (ii) any financial information that
Vulcan currently provides to Citizens  simultaneously with Vulcan providing such
information to Citizens;  and (iii) any further financial information reasonably
requested by Benteler. Vulcan shall concurrently provide Citizens with copies of
all reports and other  information which Vulcan delivers to Benteler pursuant to
this Agreement.

         (g)  Upon  Benteler's  request,  Vulcan  will use its best  efforts  to
cooperate with Benteler in the  resourcing of any or all of the Component  Parts
to an alternate source.

         (h)  Thermodynetics, in its capacity as the sole shareholder of Vulcan,
consents to Vulcan  entering into this  Agreement  and the Access  Agreement and
consents to all of the terms contained in these  agreements  including,  without
limitation,  the access rights granted to Benteler,  and will not interfere with
Vulcan's  timely  performance  of all of its  obligations  under this  Agreement
and/or the Access Agreement.  Thermodynetics  also agrees that it will take such
shareholder  action as is necessary to authorize Vulcan to consummate any of the
transactions contemplated by this Agreement or the Access Agreement.

                                       7


         (i)   Thermodynetics  also  acknowledges and reaffirms its obligations,
subject to the terms of this  Agreement,  to Benteler in connection with (i) the
unconditional  Guaranty  to  Benteler  in the  amount of  $175,000  executed  in
January,  2005 and (ii) this Agreement.  Benteler hereby acknowledges and agrees
that  Thermodynetics  has no other obligations to it, other than those expressly
described in the preceding sentence.

     7.  Acknowledgment of Ownership of Bailed Assets.

         (a)  Certain tooling and other assets owned by Benteler  (collectively,
the "Bailed Assets") are bailed at the Premises.  Vulcan and Benteler shall work
together to compile an accurate list of tooling and other assets which  comprise
the Bailed Assets on or before July 15, 2005.  Upon  compilation  of the list of
Bailed Assets, and Benteler's provision to Citizens of evidence  satisfactory to

shall have the right to  immediately  enter the Premises and take  possession of
any Equipment, Inventory or Bailed Asset, subject to (i) payment of the Purchase
Price with respect to the Equipment  and (ii) payment of the Inventory  Purchase
Price with respect to the Inventory. Vulcan agrees to cooperate with and provide

2005 and (ii) provide for staffing and operations  sufficient to build a bank of
at least 19,000 excess  Component Parts by August 15, 2005, above and beyond the
Component Parts required for Nissan's consumption during that period. The Budget
shall also provide for staffing and operations  sufficient to build a bank of at
least 12,000 excess  Component  Parts made for Toyota,  18,000 excess  Component
Parts made for CS and 16,000  excess  Component  Parts made for the Hemi also by
July 31, 2005, above and beyond the Component Parts required for each respective
OEM's consumption during that period.

         (b)   Benteler  may,  at its sole and  exclusive  discretion,  fund the
operations  of Vulcan  pursuant to the terms of the Budget.  Each week's  Budget
shall run from  Monday  through  Sunday and shall be  presented  to  Benteler by
Vulcan no later  than  noon EDT on the  Friday  of the week  preceding  the week
provided for in the Budget.  Benteler  shall notify  Vulcan  before the close of
business on the Friday prior to the week provided for in the Budget,  whether or
not the Budget is  approved  as  submitted.  To the extent  Benteler  approves a
weekly Budget, it shall be obligated to fund the week's operations in accordance
with the approved Budget.

                                       8


          (c)  Notwithstanding  the above or any funding provided by Benteler to
Vulcan,  Benteler  shall be under no obligation to approve any Budget or to fund
or continue the operations,  or pay any liability,  of Vulcan,  except as agreed
under any Budget  approved by  Benteler,  and  Benteler  may cease  funding such
operations  at any time  without  notice to any  party,  provided  that,  in all
events, Benteler shall fully fund any previously approved Budget.

         (d)  At such time as Benteler  discontinues  funding the agreed Budget,
and if Benteler  is not  otherwise  conducting  and  funding  operations  at the
Premises  under  the  Access  Agreement,  Vulcan  can,  in its sole  discretion,
terminate  operations,  and Citizens shall be free to exercise all of its rights
and remedies against Vulcan's assets (regardless of whether such assets are used
in the production of Component  Parts for Bentler).  Benteler  agrees that if it
discontinues  funding the Budget  while  Vulcan is still  indebted to  Citizens,
Benteler shall not apply the Waived Offset against any payables owed by Benteler
to Vulcan until Citizens has been paid in full.

     9.  Sublease of Premises.

         (a)  At the option of Benteler,  Vulcan  shall sublet (the  "Sublease")
the premises at which it currently  operates (the  "Premises") and, after August
15, 2005,  any other  equipment  related to other  Benteler  production  through
December 31, 2005 on a month-to-month basis,  terminable only by Benteler in its
sole discretion.  Vulcan shall obtain its landlord's  consent to the Sublease of
the Premises.  Benteler's  monthly  rental under the Sublease  shall be the same
amount  required to be paid each month to its  landlord  under the lease for the
Premises.  In the event Benteler  exercises its option to Sublease the Premises,
the Sublease  shall  terminate on the earlier of (i) the date on which  Benteler
notifies Vulcan of its intent to terminate the Sublease,  (ii) the date on which
Benteler ceases operating at the Premises, or (iii) December 31, 2005.

         (b)  No later than July 15,  2005,  all  billed and unpaid  liabilities
associated with the Premises,  including but not limited to, any (i) amounts due
from Vulcan to its landlord with respect to Vulcan's occupation of the Premises,
(ii) property taxes, or (iii) utilities, shall be paid by Vulcan down to a level
necessary to continue service of the relevant utility  uninterrupted beyond July
15, 2005.

         (c)  In the  event any  utility  takes  any  action to cease  providing
utility  service to the  Premises  related to amounts  due for  utility  service
provided  prior to July 1, 2005,  Thermodynetics  shall  immediately  pay to the
respective  utility  provider an amount  sufficient  to allow for the  continued
utility service at the Premises.  Thermodynetics'  liability under the preceding
sentence  shall  terminate  90 days after the date set forth on this  Agreement;
however,  in the  event  Benteler  is not  funding  production  of  Parts at the
Premises  either  pursuant  to the Budget or an agreed  Access  Agreement,  then
Thermodynetics's  liability  under  the  preceding  sentence  shall  immediately
terminate.

         (d)  In the  event  Benteler  exercises  its  option  to  Sublease  the
Premises,  pursuant to the Access Agreement,  Vulcan (i) grants Benteler a right
of access to the Premises for purposes of conducting  operations (subject to the
rights of Citizens)  and (ii)  provides  that Vulcan shall lease to Benteler the
necessary personnel for Benteler's required operations.

                                       9


         (e)  In the event  Benteler  exercises  its  rights  under  the  Access
Agreement or Sublease,  Benteler  hereby agrees that Citizens  shall be provided
with  reasonable  access to the  Premises  for the  purpose  of  inspecting  any
collateral  granted to  Citizens  by Vulcan or  enforcing  Citizens'  rights and
remedies against any such collateral  (including,  without  limitation,  for the
purpose of conducting a foreclosure sale of Vulcan assets).

         (f)  To the extent  Benteler  occupies the Premises  beyond  August 15,
2005, Benteler and Vulcan shall negotiate (subject to approval by Citizens), and
Benteler  shall pay to Citizens on behalf of Vulcan,  a reasonable  rental for a
period of up to thirty (30) days (or such longer period as is mutually agreed to
between  Benteler and Citizens) for the continued use of assets owned by Vulcan,
if any, after that date.

     10. Release of Benteler by Vulcan and Thermodynetics.  In consideration for
the   accommodations   that   Benteler  is  providing  to  Vulcan,   Vulcan  and
Thermodynetics  hereby for themselves and for all of their respective affiliated
companies, and for all officers, directors, partners, members,  representatives,

transferred, conveyed, abandoned, or otherwise disposed of any Claim.

ever had or now has  against  Thermodynetics  for,  upon,  or by  reason  of any
