                                CHARLES F. BARNES

                              AS OF MARCH 31, 2000

<PAGE>   4

             This ASSET PURCHASE AGREEMENT (this "Agreement") is made and
entered into as of the 31st day of March, 2000, by and among NEWCO CONSULTANTS,
LLC, a Michigan limited liability company ("Buyer"), GORDON P. SACHS, DAVID M.
SACHS and CHARLES F. BARNES (all of whom are collectively referred to herein as
"Affiliates"), and TECHTEAM CAPITAL GROUP, LLC, a Michigan limited liability
company ("Seller").

                                    RECITALS

             WHEREAS, Seller is engaged in various business activities,
including the lease of computer and other equipment (collectively, the
"Business");

             WHEREAS, upon the terms and subject to the conditions of this
Agreement, Buyer desires to purchase from Seller, and Seller desires to sell to
Buyer, certain assets owned by Seller and used in the operation of the Business,
as more specifically identified herein (the "Purchased Assets");

             WHEREAS, the Affiliates are interested in the business and affairs
of Newco and in the transactions contemplated by this Agreement;

             NOW, THEREFORE, in consideration of the mutual covenants set forth
herein and other good and valuable consideration, the receipt and legal
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

                                    ARTICLE 1
                           SALE AND PURCHASE OF ASSETS

         1.1 Agreement of Purchase and Sale. Upon the terms and subject to the
conditions of this Agreement, at the Closing, the Seller shall sell, transfer,
assign, convey and deliver (or cause to be sold, transferred, conveyed, assigned
and delivered) to Buyer, and Buyer shall purchase, accept and acquire from
Seller, all of the right, title and interest of Seller in and to the Purchased
Assets. "Purchased Assets" shall mean the loan receivables and fixed assets that
are specifically set forth on Schedule 1.1 attached hereto, and the master
leases set forth on Schedule 10.1. Except as indicated on Schedule 3.3, the
Purchased Assets will be sold free and clear of all mortgages, deeds of trust,
liens, pledges, charges, security interests, contractual restrictions, claims or
encumbrances of any kind or character (collectively, "Encumbrances").
Notwithstanding the provisions of this Section 1.1, nothing in this Agreement
will constitute a transfer or an attempted transfer of any contract document or
agreement which is not capable of being transferred without the consent,
approval, waiver or novation of a third person or entity (including, without
limitation, a governmental authority), or with respect to which such transfer or
attempted transfer would constitute a breach thereof or a violation of any law,
other than those for which such consents, approvals, waivers or novations have
been obtained by the Seller prior to the Closing Date (such nontransferable
contract documents and agreements being collectively referred to herein as the
"Unassigned Contracts"). The Seller will not be obligated to transfer to the
Buyer any of its rights and obligations in and to any of the Unassigned
Contracts without first having obtained all consents, approvals, waivers and
novations necessary for such

                                       1

<PAGE>   5

transfers under the terms of such Unassigned Contracts or applicable law, and
the failure to effect such transfer shall not constitute a breach of this
Agreement so long as the Seller uses its best efforts to obtain such consents,
approvals, waivers and/or novations following the Closing. Upon obtaining any
such consent, approval, waiver or novation necessary to transfer an Unassigned
Contract following the Closing, the Unassigned Contracts will, without further
action, be deemed to be transferred to the Buyer. To the extent that the
consents, approvals, waivers and novations referred to in this paragraph are not
obtained by the Seller, the Seller will, as to each Unassigned Contract, use its
best efforts after the Closing Date to provide to Buyer the benefits of such
Unassigned Contracts, cooperate in any lawful arrangement designed to provide
such benefits to the Buyer without incurring any obligation to any third party,
and enforce, at the request of the Buyer, at the cost of and for the account of
the Buyer, any rights of the Seller arising from any such Unassigned Contract
(including, without limitation, the right to elect to terminate in accordance
with the terms thereof upon the request of the Buyer).

             1.2 Assumed Liabilities. On the terms and subject to the conditions
of this Agreement and in reliance upon the representations and warranties
contained herein, at the Closing, the Buyer and the Affiliates shall assume and
undertake to perform all of the liabilities and obligations of the Seller
specifically described on Schedule 1.2 (the "Assumed Liabilities"). Except for
the Assumed Liabilities, neither the Buyer nor the Affiliates shall assume and
the Seller shall retain and remain responsible for, any and all liabilities and
obligations of the Seller, including all liabilities and obligations with
respect to the Business (collectively, the "Retained Liabilities").

             1.3 Purchase Price; Allocation.

                                       be paid by the Buyer for the Purchased
                                       Assets, the Buyer shall pay to the Seller
                                       the purchase price (the "Purchase Price")
                                       at the Closing as follows:

and warranty of the Seller contained in or made pursuant to this Agreement,

herewith;

                  (b) the breach or nonfulfillment of any covenant of the Seller

save the Seller, its affiliates and their respective shareholders, officers,
directors, employees, successors and assigns (each, a "Seller Indemnitee")
harmless from and against, for and in respect of, any and all demands,
judgments, injuries, penalties, damages, losses, obligations, liabilities,
claims, actions or causes of action, encumbrances, costs and expenses
(including, without limitation, reasonable attorneys' fees and expert witness

                  (a) the untruth, inaccuracy or breach of any representation

             11.4 Claims for Indemnification; Limitations. No claim for
indemnification with respect to a breach of a representation and warranty shall
be made under this Agreement after the Survival Date unless prior to the
Survival Date the Buyer Indemnitee or the Seller Indemnitee, as the case may be,
shall have given the Seller or the Buyer, as the case may be, written notice of
such claim for indemnification. Neither the aggregate liability of the Buyer for
all such claims under Section 10.3 (other than claims involving fraud or
intentional misrepresentation), on the one hand, nor the aggregate liability of
the Seller for all such claims under Section 11.2 (other than claims involving
fraud or intentional misrepresentations), on the other hand, shall exceed the
Purchase Price. The amount of any claim by the Buyer Indemnitee or the Seller
Indemnitee for indemnity hereunder shall be reduced to reflect any actual tax
savings received by the Indemnitee (as defined below) within three (3) years
from the Closing Date that result from the liability that gave rise to such
indemnity. The amount of any claim by the Buyers or the Sellers for indemnity
hereunder shall be reduced to reflect any insurance proceeds recoverable by and
paid to the Indemnitee relating to such claim, provided that the foregoing
reduction shall not be applied if to do so would excuse any insurer from any
obligation to cover any loss.

             11.5 Claims.

                  (a) Any claim for indemnity under Section 11.2 or 11.3 shall
be made by written notice from the party seeking to be indemnified (the
"Indemnitee") to the party from which indemnification is sought (the
"Indemnifying Party") specifying in reasonable detail the basis of the claim.

                  (b) When an Indemnitee seeking indemnification under Section
11.2 or 11.3 receives notice of any claims made by third parties ("Third Party
Claims") which is to be the basis for a claim for indemnification hereunder, the
Indemnitee shall give written notice within a reasonable

                                       10

<PAGE>   14

period thereof to the Indemnifying Party reasonably indicating the nature of
such claims and the basis thereof. Upon notice from the Indemnitee, the
Indemnifying Party may, but shall not be required to, assume the defense of any
such Third Party Claim, including its compromise or settlement, and the
Indemnifying Party shall pay all reasonable costs and expenses thereof and shall
be fully responsible for the outcome thereof, provided, however, that (i) the
Indemnifying Party shall not settle any such claim without the Indemnitee's
prior written consent (which consent shall not be unreasonably withheld) unless
the only remedy for such claim is monetary damages which are paid in full by the
Indemnifying Party, and (ii) the Indemnifying Party shall not, without the
written consent of the Indemnitee, settle or compromise any claim which does not
include as an unconditional term thereof the giving by the claimant or the
plaintiff to Indemnitee, a release from all liability in respect to such claim.
In connection with any claim involving any remedy other than monetary damages,
the Indemnitee shall have the right to be kept informed and be consulted in
connection with the resolution of such claim. The Indemnifying Party shall give
notice to the Indemnitee as to its intention to assume the defense of any such
Third Party Claim within twenty (20) days after the date of receipt of the
Indemnitee's notice in respect of such Third Party Claim. If an Indemnifying
Party does not give notice to the Indemnitee of its assumption of the defense of
the Third Party Claim within twenty (20) days after the Indemnitee's notice is
given, the Indemnifying Party shall be deemed to have waived its rights to
control the defense thereof. If the Indemnitee assumes the defense of any Third
Party Claim because of the failure of the Indemnifying Party to do so in
accordance with this Section 10.5, the Indemnifying Party shall pay all
reasonable costs and expenses of such defense and shall be fully responsible for
the outcome thereof. The Indemnifying Party shall have no liability with respect
to any compromise or settlement thereof effected without its prior written
consent, which consent shall not be unreasonably withheld.

                  (c) Both the Indemnitee and the Indemnifying Party shall
cooperate fully with one another in connection with the defense, compromise or
settlement of any such claim, proceeding or action, including, without
limitation, by making available to the other all pertinent information and
witnesses within its control.

             11.6 Effectiveness.  The provisions of this Article 11 shall be
effective  upon  consummation  of the Closing,  and prior to the Closing, shall
have no force and effect.

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is made as of
March 31, 2000, by and among National TechTeam, Inc., a Delaware corporation
(the "Company"), and David M. Sachs, Charles F. Barnes Gordon P. Sachs and
Stephen D. Sachs (each individually a "Shareholder" and collectively the
"Shareholders").

         WHEREAS, the Company and the Shareholders are parties to a certain
Separation and Release Agreement of even date herewith (the "Separation
Agreement"), pursuant to which the Company has agreed to provide the
registration rights set forth in this Agreement. Unless otherwise provided in
this Agreement, capitalized terms used herein shall have the meanings set forth
in paragraph 1 hereof.

         NOW, THEREFORE, the parties hereto agree as follows:

1.       DEFINITIONS.  As used in this Agreement, the following terms shall have
the meanings ascribed to them below:

         (a) "Business Day" means any Monday, Tuesday, Wednesday, Thursday or

Michigan, are authorized by law, regulation or executive order to close.

         (b) "Common Stock" means the common stock, par value $0.01 per share,
of the Company.

         (c) "Demand Registration Statement" shall have the meaning set forth in
Section 2.

         (d) "Contingent Shares" means the shares of Common Stock issued
pursuant to the Separation Agreement.

         (e) "Prospectus" has the meaning set forth in Section 5.

offer. For purposes of this Agreement, a Registrable Security ceases to
constitute a Registrable Security (i) when such Registrable Security shall have
been effectively registered under the Securities Act and disposed of in a public
market transaction pursuant to a Registration Statement, (ii) when such
Registrable Security shall have been sold pursuant to Rule 144 (or any successor
provision) under the Securities Act, (iii) when such Registrable Security shall
have been otherwise transferred and a new certificate for such Registrable
Security not bearing a legend restricting further transfer shall have been
delivered by the Company following the Company's receipt of an opinion of
counsel reasonably satisfactory to it that the issuance and delivery of such a
certificate is legal and proper under this Agreement and applicable law, (iv)
with respect to a particular Shareholder, on the date on which all of that
Shareholder's remaining Registrable Securities could be sold in a single
transaction in compliance with Rule 144 under the Securities Act, or (v) when
such Registrable Security shall have ceased to be outstanding.

         (j) "Registration Statement" means a Piggyback Registration Statement
or a Demand Registration Statement.

         (k) " Representative" means Charles F. Barnes.

         (l) "Securities Act" means the Securities Act of 1933, as amended.

         (m) "Termination Date" means the first date on which no Registrable
Securities are outstanding.

         (n) Other terms shall have the meaning ascribed to them in the recitals
and other sections of this Agreement.

2.       DEMAND REGISTRATION.

         a) Demand. Upon repayment of all indebtedness owed to the Company by
all of the Shareholders or any affiliates of the Shareholders, the Shareholders
shall have the right to require the Company to file one registration statement
(the "Demand Registration Statement") with the Securities and Exchange
Commission under the Securities Act, covering the sale of not less than 50,000
and not more than 350,000 shares of Registrable Securities. The right of the
Shareholders to require the Company to file a Demand Registration Statement
shall be exercised on behalf of the Shareholders by the Representative giving
written notice to the Company indicating the Shareholders who wish to have
Registrable Securities included in the Demand Registration and the amount of
Registrable Securities to be included for each such Shareholder. Upon receipt of
such notice the Company will follow the procedures contained in Sections 5 and
6, provided that, in any event, the Demand Registration Statement shall be filed
with the Securities and Exchange Commission within 60 days after the Company
shall have received such notice from the Representative or as soon thereafter as
practicable. Subject to Section 3(c) below, all of the Shareholders shall be
entitled to participate in the Registration;

                                       2
<PAGE>   36

provided, however, that the aggregate number of shares to be registered shall
not exceed 350,000.

         (b) Number of Shares. In the event that the Shareholders have sold
Registrable Securities pursuant to a Piggyback Registration Statement prior to
the exercise of the right to a Demand Registration, the maximum amount of
Registrable Securities shares that may be sold pursuant to a Demand Registration
will be reduced by the amount of Registrable Securities sold pursuant to a
Piggyback Registration Statement.

3.       PIGGYBACK REGISTRATIONS.

         (a) Notice. Whenever the Company proposes to register any of its Common
Stock under the Securities Act for sale in an underwritten public offering,
other than pursuant to a registration on Form S-8 or Form S-4, or any other form
which in the future may be approved by the SEC in lieu of such forms for the
same purposes (a "Piggyback Registration"), the Company will give prompt written
notice to all holders of Registrable Securities of its intention to effect such
a registration and will, subject to Sections 3(c) and 3(d), include in such
registration all Registrable Securities with respect to which the Company has
received written requests for inclusion therein within 15 days after the receipt
of the Company's notice.

         (b) Priority in Primary Registrations. If a Piggyback Registration is
an underwritten offering on behalf of the Company, and the managing underwriters
advise the Company in writing that in their opinion the number of securities
requested to be included in such registration exceeds the number which can be
sold in such offering without adversely affecting the marketability of the
offering, the Company will include securities in such registration in the
following order of priority: (i) first, the securities the Company proposes to
sell, and (ii) second, the Registrable Securities requested to be included in
such registration by the Shareholders and all Common Stock requested to be
included in such registration by other holders of Common Stock having
registration rights (the "Other Common Stock"), pro-rata based on the respective
number of shares of Common Stock held by each Shareholder and other holder of
Common Stock.

         (c) Priority in Secondary Registrations. If a Piggyback Registration is
an underwritten secondary offering on behalf of holders of the Company's
securities, and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in such offering without
adversely affecting the marketability of the offering, the Company will include
securities in such registration in the following order of priority: (i) first,
the Registrable Securities requested to be included in such registration by the
Shareholders requesting such registration, (ii) second, all Other Common Stock
requested to be included in such registration by other holders of Common Stock
having registration rights (except for such Common Stock included in the
immediately preceding clause (i)), pro-rata based on the respective number of
shares of Common Stock held by each

                                       3
<PAGE>   37

Shareholder and other holders of Common Stock, and (iii) third, additional
securities of the Company requested to be included in such registration.

4.       Holdback Agreements. Each holder of Registrable Securities agrees not
to effect any public sale or distribution (including sales pursuant to Rule144)
of equity securities of the Company, or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and the 90-day period beginning on the effective date of any underwritten
Piggyback Registration in which Registrable Securities are included (except as
part of such underwritten registration), unless the underwriters managing the
registered public offering otherwise agree.

5.       Registration Procedures.

         (a)      Company Procedures.

                  (i) Whenever this Agreement requires, or the holders of
Registrable Securities have requested (as permitted hereunder), that any
Registrable Securities be registered pursuant to this Agreement, the Company
will use all reasonable efforts to effect the registration and the sale of such
Registrable Securities in accordance with the intended method of disposition
thereof, and pursuant thereto the Company will, as expeditiously as possible,
subject to the requirement set forth in Section 2(a) of the Company filing a
Demand Registration Statement within 60 days or as soon thereafter as
practicable:

                           (A) prepare and file with the Securities and Exchange
                  Commission a Registration Statement with respect to such
                  Registrable Securities and use all reasonable efforts to cause
                  such registration statement to become effective as soon as
                  practicable thereafter;

                           (B) prepare and file with the Securities and Exchange
                  Commission such amendments and supplements to such
                  Registration Statement and the prospectus used in connection
                  therewith (the "Prospectus") as may be necessary to keep such
                  Registration Statement effective for a period of not less than
                  ninety (90) days (plus, in the case of the Demand
                  Registration, any extension period required pursuant to
                  Section 6(b) plus any period during which the Shareholders are
                  unable to sell Registrable Securities due to an event
                  described in Section 5(a)(i)(F)) and comply with the
                  provisions of the Securities Act with respect to the
                  disposition of all securities covered by such Registration
                  Statement during such period;

                           (C) furnish each seller of Registrable Securities
                  such number of copies of such Registration Statement, each
                  amendment and supplement thereto, the Prospectus included in
                  such Registration Statement (including each preliminary
                  Prospectus) and such other documents as such seller may

                                       4
<PAGE>   38

                  reasonably request in order to facilitate the disposition of
                  the Registrable Securities owned by such seller;

                           (D) use all reasonable efforts to register and
                  qualify such Registrable Securities under the securities or
                  blue sky laws of such states and the District of Columbia as
                  any seller of Registrable Securities reasonably requests and
                  do any and all other acts and things which may be reasonably
                  necessary or advisable to enable such seller to consummate the
                  disposition in such states and the District of Columbia of the
                  Registrable Securities owned by such seller (provided that the
                  Company will not be required to (i) qualify generally to do
                  business in any jurisdiction where it would not otherwise be
                  required to qualify but for this subparagraph, (ii) subject
                  itself to taxation in any such jurisdiction or (iii) consent
                  to general service of process in any such jurisdiction);

                           (E) notify each seller of such Registrable Securities
                  of the happening of any event of which the Company becomes
                  aware, as a result of which the Prospectus included in such
                  Registration Statement contains an untrue statement of a
                  material fact or omits any fact necessary to make the
                  statements therein not misleading, and, at the request of any
                  such seller, as promptly as is practicable, the Company will
                  prepare a supplement or amendment to such Prospectus so that,
                  as thereafter delivered to the purchasers of such Registrable
                  Securities, such Prospectus will not contain an untrue
                  statement of a material fact or omit to state any fact
                  necessary to make the statements therein not misleading;

                           (F) notify each seller of any securities covered by
                  such Registration Statement (1) when such Registration
                  Statement, or any post-effective amendment to such
                  Registration Statement, shall have become effective, or any
                  amendment of or supplement to the Prospectus used in
                  connection therewith shall have been filed, (2) of any request
                  by the Securities and Exchange Commission to amend such
                  Registration Statement or to amend or supplement such
                  Prospectus or for additional information, (3) of the issuance
                  by the Securities and Exchange Commission of any stop order
                  suspending the effectiveness of such Registration Statement or
                  of any order preventing or suspending the use of any
                  preliminary prospectus, (4) of the suspension of the
                  qualification of such securities for offering or sale in any
                  jurisdiction, or of the institution of any proceedings for any
                  of such purposes, (5) of the happening of any event that makes
                  any statement made in such Registration Statement, any then
                  effective Prospectus or any other document incorporated
                  therein by reference untrue or that requires the making of any
                  changes in such Registration Statement, Prospectus or any
                  document incorporated therein by reference in order that such
                  documents not contain any untrue statement of a material fact
                  or omit to state any material fact required to be

                                       5
<PAGE>   39

                  stated therein or necessary to make the statements therein not
                  misleading, and (6) of the Company's determination that a
                  further post-effective amendment to such Registration
                  Statement would be appropriate;

                           (G) use reasonable efforts to cause all such
                  Registrable Securities to be listed on the NASD automated
                  quotation system;

                           (H) otherwise use all reasonable efforts to comply
                  with all applicable rules and regulations of the Securities
                  and Exchange Commission, and make available to its security
                  holders, as soon as reasonably practicable, an earnings
                  statement covering the period of at least twelve months
                  beginning with the first day of the Company's first full
                  calendar quarter after the effective date of the Registration
                  Statement, which earnings statement shall satisfy the
                  provisions of Section 11(a) of the Securities Act and Rule 158
                  thereunder; and

                           (I) in the event of the issuance of any stop order
                  suspending the effectiveness of a Registration Statement, or
                  of any order suspending or preventing the use of any related
                  Prospectus or suspending the qualification of any Common Stock
                  included in such Registration Statement for sale in any
                  jurisdiction, the Company will use all reasonable efforts
                  promptly to obtain the withdrawal of such order.

          (b)     Shareholder Procedures.

                  (i) In connection with any Registration Statement, the Company
         may require each Shareholder to furnish to the Company such information
         regarding such Shareholder and his or her proposed distribution of
         Registrable Securities, to the extent necessary to comply with the
         Securities Act, as the Company may from time to time reasonably request
         in writing.

                  (ii) Each Shareholder agrees to cooperate and timely provide
         all necessary information to the Company in all reasonable respects in
         connection with the preparation and filing of each Registration
         Statement and any amendment thereof, any Prospectus relating thereto
         and any Prospectus supplement relating thereto with respect to the
         offer and sale of Registrable Securities of such Shareholder.

6.       Demand Registration Selling Restrictions. The following provisions
shall apply to the Demand Registration:

         (a) Notice to Company. The Representative agrees to notify the Company
at least two (2) Business Days prior to any disposition of Registrable
Securities pursuant to the Demand Registration Statement of a Shareholder's
intent to dispose of such Registrable Securities. Such notice shall be in
writing, by facsimile or by a telephone conversation with either the Company's
Chief Financial Officer, General Counsel or Director of Investor Relations, at
the address, facsimile number or the phone number, as the case may be, of the
Company, all as set forth in Section 11 below. The Company will exert reasonable
efforts to respond to such notice by the next Business Day, but in any event,
the Company shall respond no later than the second Business Day following the
date of receipt. Such response shall consist of one of the following:

                  (i) an oral or written confirmation that the Company knows of
         no reason why the Shareholder should not proceed with the proposed sale
         or disposition; or

                  (ii) a notification that the proposed disposition must be
         delayed for a period of up to thirty (30) days as provided in Section
         6(b) or

                  (iii) a confirmation from either the Chef Financial Officer or
         the General Counsel of the Company that the Company requires a limited
         time, not to exceed five (5) Business Days following the receipt of the
         Company's receipt of the Shareholder's notice, within which to
         determine which of the foregoing responses is appropriate under the
         circumstances.

         (b) Restriction on Sale. The Company may restrict disposition of such
Registrable Securities, in which event each Shareholder agrees not to dispose of
such Registrable Securities; provided that:

                  (i) the Company shall have delivered a notice in writing to
         the Representative stating that a delay in the disposition of
         Registrable Securities is necessary because the Company, in its
         reasonable judgment, exercised in good faith, has determined that such
         sales of Registrable Securities would require public disclosure by the
         Company of material nonpublic information that the Company deems
         advisable not to disclose;

                  (ii) in the event of the delivery of the notice described in
         (i) above by the Company, the Company shall exert commercially
         reasonable efforts to amend the Demand Registration Statement or amend
         or supplement the Prospectus, if necessary and to take all other
         actions necessary to allow the proposed disposition to take place as
         promptly as practicable after the conditions referred to therein have
         ceased to exist;

            (iii) the Company agrees to use all commercially reasonable
         efforts to keep the Demand Registration Statement, as amended pursuant
         to this Section 6(b), effective for an additional period of time equal
         to the period during which sales were restricted pursuant to this
         Section 6(b).

         (c) Discontinuance of Sale. Each Shareholder agrees that, upon receipt
of any notice from the Company of the happening of any event of the kind
described in any of Sections 5(a)(i)(F)(1)-(6), such Shareholder shall forthwith
discontinue all sales and distributions of Registrable Securities pursuant to
the then-current Prospectus until the Representative receives copies of a
supplemental or amended Demand Prospectus as contemplated by Section 6(c)(ii),
or until the Representative is advised in writing by the Company that the use of
the Prospectus may be resumed, and, if so directed by the Company, the
Representative will deliver to the Company all copies then in the possession of
the Shareholders of the Prospectus in effect with respect to the Registrable
Securities at the time of such notice by the Company. The Company shall promptly
take all such action as may be necessary or appropriate, including, without
limitation, the filing of an amendment to the Demand Registration Statement
and/or the filing of an amended Prospectus or a Prospectus supplement, to limit
the duration of any discontinuance with respect to the sale and distribution of
Registrable Securities pursuant to this Section 6(d).

         (e) Restrictions Cumulative. The restrictions described herein are in
addition to, and not in limitation of, any other restrictions that may be
applicable to each of the Shareholders, including, without limitation any
restrictions under applicable securities laws (such as the Company's employee
insider trading policy and general restrictions against trading in Company
securities while in possession of material non-public information concerning the
Company).

         7.  Registration Expenses.

         (a) The Company will bear all expenses of registration, except for any
underwriting spread and brokerage commission and transfer taxes incurred in
connection with sales of the Registrable Stock and except for expenses of any
legal counsel selected by the Shareholders to represent them in connection with
the sale of the Registrable Stock.

         (b) Payment by Selling Shareholders. To the extent registration
expenses are not required to be paid by the Company, each holder of securities
included in any registration hereunder will pay those registration expenses
allocable on a share-by-share basis to the registration of such holder's
securities so included, and any registration expenses not so allocable will be
borne by all sellers of securities included in such registration in proportion
to the aggregate selling price of the securities to be so registered.

8.       Indemnification.

         (a) Company Indemnification. The Company shall indemnify and hold
harmless, to the fullest extent permitted by law, each seller of Registrable
Securities, any underwriter for such registration and each person or entity, if
any, controlling such seller or underwriter within the meaning of the Securities
Act or the Exchange Act against all losses, claims, damages, liabilities and
expenses (including reasonable costs of investigation and legal expenses) to
which such seller, underwriter or controlling person or entity, as the case may
be, may become subject under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages, liabilities or
expenses (or actions in respect thereof) arise out of or are based upon any of
the following (collectively, "Violations"):

                  (ii) any untrue statement or alleged untrue statement of a
         material fact contained in any Registration Statement, any Prospectus
         or any amendments or supplements thereto;

                  (ii) the omission or alleged omission to state therein a
         material fact required to be stated therein, or necessary to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading; or

                  (iii) any violation or alleged violation by the Company, in
         connection with such registration, of the Securities Act, the Exchange
         Act, any state securities law or any rule or regulation promulgated
         under the Securities Act, the Exchange Act or any state securities law;

provided, however, that the Company shall not be liable in any such case for any
such loss, claim, damage, liability or action to the extent that it arises out
of or is based upon a Violation which occurs in reliance upon and in conformity
with written information furnished for use in connection with such registration
by any such seller, underwriter or controlling person or entity.

         (b) Selling Shareholder Indemnification. Each seller of Registrable
Securities shall indemnify and hold harmless, to the fullest extent permitted by
law, the Company, its officers, directors, employees, representatives and
agents, and each Person who controls (within the meaning of the Securities Act)
the Company, against all losses, claims, damages, liabilities and expenses
(including reasonable costs of investigation and legal expenses) resulting from
any untrue or alleged untrue statement of a material fact contained in any
Registration Statement, any Prospectus, or any amendment or supplement thereto,
and any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, to the extent the same
arises out of or is based upon any untrue statement or alleged untrue statement
of a material fact or any omission or alleged omission to state a material fact
in such Registration Statement, Prospectus, amendment or supplement, as the case
may be, made or omitted, as the case

                                       9
<PAGE>   43

may be, in reliance upon and in conformity with written information furnished to
the Company by such seller for use therein, or if such offering is not an
underwritten offering, by such seller's failure to deliver a copy of the
Registration Statement, Prospectus or any amendment or supplement thereto after
the Company has furnished such seller with a sufficient number of copies of the
same. In no event shall any indemnification obligation under this Section 8(b)
or by any seller under Section 8(d) exceed the net proceeds from the offering
received by such seller.

         (c) Notice of Claim. Each party entitled to indemnification under this
Section 8 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided, that counsel for the
Indemnifying Party, who will conduct the defense of such claim or litigation, is
approved by the Indemnified Party (whose approval will not be unreasonably
withheld or delayed); and provided, further, that the failure of any Indemnified
Party to give notice as provided herein shall not relieve the Indemnifying Party
of its obligations except to the extent that its defense of the claim or
litigation involved is prejudiced by such failure. The Indemnified Party may
participate in such defense at such party's expense. No Indemnifying Party, in
the defense of any such claim or litigation, except with the consent of each
Indemnified Party, shall consent to entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect of any claim or litigation, and no Indemnified Party will
consent to entry of any judgment or settle any claim or litigation without the
prior written consent of the Indemnifying Party. Each Indemnified Party shall
furnish such information regarding himself, herself or itself and the claim in
question as the Indemnifying Party may reasonably request and as shall be
reasonably required in connection with the defense of such claim and litigation
resulting therefrom.

         (d) Contribution. If for any reason the indemnification provided for in
this Section 8 from an Indemnifying Party, although otherwise applicable by its
terms, is determined by a court of competent jurisdiction to be unavailable to
an Indemnified Party hereunder, then the Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by the Indemnified Parties as a result of such losses, claims, damages,
liabilities or expenses in such proportion as is appropriate to reflect the
relative fault of such Indemnifying Party and the Indemnified Parties in
connection with the actions that resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and the Indemnified Parties shall
be determined by reference to, among other things, whether any action in
question, including any untrue or alleged untrue statement of a material fact,
has been made by, or relates to information supplied by, such Indemnifying Party
or the Indemnified Parties, and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such action. The amount
paid or payable by a party as a result of the losses, claims, damages,
liabilities

                                       10
<PAGE>   44

and expenses referred to above shall be deemed to include, subject
to the limitations set forth in Section 8(c), any legal or other fees or
expenses reasonably incurred by such party in connection with any investigation
or proceeding.

9.       Participation in Underwritten Registrations. No Person may participate
in any underwritten registration hereunder unless such Person (a) agrees to sell
such Person's securities on the basis provided in any underwriting arrangements
approved by the Company and other Person or Persons entitled hereunder to
approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements.

10.      Reports Under Exchange Act. With a view to making available to the
holders of the Registrable Securities the benefits of Rule 144 and any other
rule or regulations of the Securities and Exchange Commission that may at any
time permit a holder to sell securities of the Company to the public without
registration, the Company agrees to use its reasonable best efforts to do all of
the following:

         (a) Public  Information.  Make and keep public information available
as contemplated in Rule 144, at all times;

         (b) SEC Reports. File with the Securities and Exchange Commission all
reports and other documents required of the Company under the Securities Act and
the Exchange Act; and

         (c) Rule 144 Statement. Furnish to any holder, so long as such holder
owns any of the Registrable Securities, forthwith upon request a written
statement by the Company that it has complied with the reporting requirements of
Rule 144, the Securities Act and the Exchange Act (at any time after it has
become subject to such reporting requirements), a copy of the most recent annual
or quarterly report of the Company and such other reports and documents so filed
with the Securities and Exchange Commission by the Company as may be reasonably
requested in availing any holder, under any rule or regulation of the Securities
and Exchange Commission, of the right to sell any such Registrable Securities
without registration.

11.      Miscellaneous.

         (a) No Inconsistent Agreements. The Company will not hereafter enter
into any agreement with respect to its securities which violates the rights
granted to the holders of Registrable Securities in this Agreement.

         (b) Remedies. Any Person having rights under any provision of this
Agreement will be entitled to enforce such rights specifically to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. The parties hereto agree and
acknowledge that money damages

                                       11
<PAGE>   45

may not be an adequate remedy for any breach of the provisions of this Agreement
and that any party may in its sole discretion apply to any court of law or
equity of competent jurisdiction (without posting any bond or other security)
for specific performance and for other injunctive relief in order to enforce or
prevent violation of the provisions of this Agreement.

         (c) Amendments and Waivers. Except as otherwise provided herein, the
provisions of this Agreement may be amended or waived only upon the prior
written consent of the Company and holders of at least a majority of the
Registrable Securities.

         (d) Successors and Assigns. All covenants and agreements in this
Agreement by or on behalf of any of the parties hereto will bind and inure to
the benefit of the respective successors and permitted assigns. No Shareholder
may assign his or her rights or obligations under this Agreement without the
prior written consent of the Company.

         (e) Severability. Whenever possible, each provision of this Agreement
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be prohibited by or
invalid under applicable law, such provision will be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
this Agreement.

         (f) Counterparts. This Agreement may be executed in two or more
counterparts, any one of which need not contain the signatures of more than one
party, but all such counterparts taken together will constitute one and the same
Agreement.

         (g) Descriptive Headings. The descriptive headings of this Agreement
are inserted for convenience only and do not constitute a part of this
Agreement.

         (h) Governing Law. The corporate law of Delaware will govern all issues
concerning the relative rights of the Company and its shareholders. All other
questions concerning the construction, validity and interpretation of this
Agreement will be governed by the internal law, and not the law of conflicts, of
Michigan.

         (i) Notices. All notices or other communications which are required or

                        SEPARATION AND RELEASE AGREEMENT

         AGREEMENT dated as of the 31st day of March, 2000 by and among National
TechTeam, Inc., a Delaware corporation ("TechTeam"); TechTeam Capital Group,
LLC, a Michigan limited liability company ("TTCG"), and David M. Sachs ("David
Sachs"), Charles F. Barnes ("Barnes") Gordon P. Sachs ("Gordon Sachs") and
Stephen D. Sachs ("Stephen Sachs") The foregoing individuals are hereinafter
collectively referred to as the "Employees."

                                    RECITALS

         WHEREAS, David Sachs is an employee of TTCG under a certain Employment
Agreement dated as of January 31, 1998 ("Employment Agreement");

         WHEREAS, Barnes, Gordon Sachs and Stephen Sachs are presently employees
of TTCG;

         WHEREAS, Newco Consultants, LLC, a new company, organized by certain of
the Employees wishes to purchase certain of the assets of TTCG, which
transaction is the subject of a separate agreement and instruments between the
parties hereto or their affiliates ("TTCG Sale"); and

         WHEREAS, Employees on the one hand, and TechTeam and TTCG on the other
hand, each wish to terminate the existing relationships between them and, except
for certain limited rights and obligations that are specifically reserved or
excluded herein, fully and finally to release each other from any and all
liability existing by virtue thereof or from any other reason or thing.

         NOW THEREFORE, in consideration of the premises and the mutual
covenants set forth herein, and other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereby
agree as follows:

         1. Contingent Shares. TechTeam agrees, subject to the terms and
conditions set forth herein, to issue to the Employees the number of shares of
the restricted common stock of TechTeam ("Contingent Shares"), which shall be
determined as set forth below and which shares shall be issued to the Employees
in the nearest whole shares that equal the proportions set forth opposite their
names:

         David Sachs       -       50%
         Charles Barnes    -       25%
         Gordon Sachs      -       25%

Issuance of the Contingent Shares shall be subject to the following terms and
conditions:

                  (a) the number of shares to be issued shall be determined as
         follows:

<PAGE>   49

                           (i) Step One: the attached Schedule 1 contains a
                  preliminary calculation of the number of Contingent Shares
                  that has been determined based solely upon (A) the actual
                  financial results of TTCG for the period from 2/1/98 through
                  2/29/00 and (B) pro-forma financial results of TTCG for the
                  period from 3/1/00 through 12/31/01. The Contingent Shares
                  shown on Schedule 1 shall be the "Base Number" for purposes of
                  the calculation.

                           (ii) Step Two: Not later than January 31, 2001,
                  TTCG's accountants shall prepare TTCG's financial statements
                  for the ten months ended 12/31/00 in accordance with generally
                  accepted accounting principles, consistently applied. Schedule
                  1 shall then be revised (to prepare a "Revised Schedule 1") as
                  follows:

                           (A)  TTCG's net operating income for the ten months
                                ended 12/31/00 shall be substituted for the same
                                period results in the pro-forma financial
                                results referenced in (i)(B) above and,

                           (B)  only in the event that TTCG's net operating
                                income for the ten months ended 12/31/00 is
                                greater than or less than the Profit/Loss shown
                                on Schedule 1 by a factor of 15%, Employees will
                                prepare, or cause to be prepared, a revised
                                pro-forma financial projection for TTCG for 2001
                                which will be prepared consistently with the
                                methodology and principles utilized in the
                                preparation of (i)(B) above, and that revised
                                pro forma shall be substituted for the pro forma
                                referenced in (i)(B) above.

                           Following the above calculations, the Base Number of
                           Contingent Shares will be increased or reduced, as
                           appropriate, by the difference, if any, between the
                           original Schedule 1 and the Revised Schedule 1. That
                           resulting number of Contingent Shares will be the
                           number to be issued to the Employees and TechTeam
                           shall, no later than February 15, 2001 instruct its
                           transfer agent to issue the proper number shares to
                           Employees. Notwithstanding any of the foregoing, in
                           no event shall the number of Contingent Shares exceed
                           325,000 shares of TechTeam stock.

                  (b) For the purpose of determining the Contingent Amount and
         the number of Contingent Shares, the parties agree that interest on
         inter-company borrowings between TTCG and TechTeam prior to March 31,
         2000 shall be included as a cost item. The parties further agree that
         for the

                                       2

<PAGE>   50

         period between April 1, 2000 and December 31, 2001, interest on
         intercompany borrowings between TTCG and TechTeam shall not be included
         as a cost item for purposes of determining the Contingent Amount and
         the number of Contingent Shares and in addition any future gains or
         losses to TTCG that result from the sale of assets that are coming off
         Leases shall be excluded from calculation of the Contingent Amount and
         the number of Contingent Shares.

                  (c) The pro-forma financial results have been prepared solely
         by the Employees without any direction or influence from any other
         persons. The parties further confirm that neither TechTeam nor TTCG
         shall have any obligation (nor do they have any intention) to take any
         actions to increase the business of TTCG.

                  (d) The accounting effect of any sale, transfer, assignment,
         or disposition of any of TTCG's right, title, or interest in the assets
         of TTCG shall have no effect upon the calculation of the Contingent
         Amounts or the number of Contingent Shares.

                  (e) Any change by either TTCG, its parent company, or its
         outside public accountants in the carrying value or rate of
         depreciation of any of TTCG's assets (except for assets added to the
         portfolio for the first three months of 2000) shall have no effect for
         purposes of calculating the Contingent Amount or the number of
         Contingent shares.

                  (f) Issuance of the Contingent Shares shall be subject to the
         condition precedent that all outstanding indebtedness under the
         promissory notes ("Notes") given by Newco and by the Employees to TTCG
         in connection with the TTCG Sale shall have been discharged. In the
         event such indebtedness shall not have been discharged by January 31,
         2001, TechTeam shall be entitled to direct the transfer agent to issue
         to it the nearest whole number of Contingent Shares, based upon the

between TechTeam Capital Group, LLC, a Michigan Limited Liability Company
("TTCG"), and Newco Consultants, LLC, a Michigan limited liability company
("NEWCO"). TTCG and NEWCO are sometimes referred to hereafter as the "Parties."

         when such re-lease or sale is in accordance with the terms of the
         master lease or the equipment schedule then in effect.

                  1.3 INDEPENDENT CONTRACTOR RELATIONSHIP. The parties agree

         provided Re-Marketing Services under Section 1.2 of this Agreement,
         TTCG shall pay NEWCO a quarterly fee (the "Re-Marketing Fee") equal to
         100 percent of the amount, if any, by which the aggregate cash received

         where NEWCO has provided Re-Marketing Services under Section 1.2 of
         this Agreement, TTCG shall also pay NEWCO a quarterly fee equal to 100
         percent of the amount, if any, by which the aggregate cash received

         calendar quarter. A listing of those leases with booked estimated
         residuals and those with no booked estimated residuals is attached as
         Schedule B. In addition, TTCG shall pay NEWCO 100 percent of the cash
         received from re-marketing agreements on sold leases where TTCG has
         booked no estimated residual value.

         2000.

            and hold harmless TTCG and any parent, subsidiary or affiliate
            thereof, and all directors, officers. employees, agents and
            consultants of each of the foregoing (collectively, the "Indemnified
            TTCG Parties" and individually an "Indemnified TTCG Party") from and
            against all demands, claims, actions or causes of action,
            assessments, losses, damages, liabilities (whether absolute, or
            accrued, contingent or otherwise), costs and expenses, including but
            not limited to, interest, penalties and attorneys' fees and expenses
            (collectively, "Damages"), asserted against, imposed upon or
            incurred by any Indemnified TTCG Party, directly or indirectly, by
            reason of or resulting from or relating to any of the following:

                    (i) Misrepresentation or breach by NEWCO of any warranty or
                 covenant or term or condition made or contained in this
                 Agreement or in any certificate, schedule or other instrument
                 furnished or to be furnished to TTCG under this Agreement;

                    (ii) Litigation or other claims arising from the acts or
                 failures to act of NEWCO in accordance with (A) applicable
                 federal, state or local statute, ordinance or common law or (B)
                 the terms and conditions of this Agreement.

            The only exclusion from this indemnification provision is liability
            arising from negligent acts or omissions of TTCG.

<PAGE>   61

                (b) NOTICE AND DEFENSE OF CLAIMS. If requested by NEWCO or if
            the Indemnified TTCG Party so desires, the Indemnified TTCG Party
            shall tender the defense to NEWCO of any matter for which the
            Indemnified TTCG Party believes it is entitled to indemnification
            pursuant to Section 6.1(a) of this Agreement, in which event NEWCO
            shall conduct such defense at its sole cost and thereafter be liable
            for all Damages with respect to such claim or proceeding. Such
            notice shall be given in accordance with Section 7.7 hereof.

                If NEWCO elects to assume control of such defense or settlement,
            it shall conduct such defense or settlement in a manner reasonably
            satisfactory and effective to protect the Indemnified TTCG Party
            fully; NEWCO and its counsel will keep the Indemnified TTCG Party
            fully advised as to the conduct of such defense or settlement, and
            no compromise or settlement shall be agreed or made without the
            Indemnified TTCG Party's written consent. In any case, the
            Indemnified TTCG Party shall have the right to employ its own
            counsel and such counsel may participate in such action, but the
            reasonable fees and expenses of such counsel shall be at the expense
            of the Indemnified TTCG Party, when and as incurred unless (A) the
            employment of counsel by the Indemnified TTCG Party has been
            authorized in writing by NEWCO, (B) the Indemnified TTCG Party shall
            have reasonably concluded that there may be a conflict of interest
            between NEWCO and the Indemnified TTCG Party in the conduct of the
            defense of such action, or (C) NEWCO shall not in fact have employed
            independent counsel reasonably satisfactory to the Indemnified TTCG
            Party to assume the defense of such action and shall have been so
            notified by the Indemnified TTCG Party. If clause (B) or (C) of the
            preceding sentence shall be applicable, then counsel for the
            Indemnified TTCG Party shall have the right to direct the defense of
            such claim, action, suit or proceeding on behalf of the Indemnified
            TTCG Party and the reasonable fees and disbursements of such counsel
            shall constitute Damages hereunder.

                The Indemnified TTCG Party and NEWCO, as the case may be, shall
            be kept fully informed of such claim, action, suit or proceeding at
            all stages thereof, whether or not such party is represented by its
            own counsel.

            6.2 INDEMNIFICATION OF NEWCO BY TTCG.

                (a) INDEMNIFICATION. TTCG hereby agrees to indemnify, defend and
            hold harmless NEWCO and any parent, subsidiary or affiliate thereof,
            and all directors, officers, employees (except the Leased
            Employees), agents and consultants of each of the foregoing
            (collectively, the "Indemnified NEWCO Parties," and individually, an
            "Indemnified NEWCO Party") from and against all demands, claims,
            actions or causes of action, assessments, losses, damages,
            liabilities, (whether absolute, or accrued, contingent or
            otherwise), costs and expenses, including but not limited to,
            interest, penalties and attorneys' fees and expenses (collectively,
            "Damages"), asserted against, imposed upon or incurred

                                       5
<PAGE>   62

            by any Indemnified NEWCO Party, directly or indirectly, by
            reason of or resulting from or relating to any of the following:

                        (i)  Misrepresentation or breach by TTCG of any
                    warranty or covenant or term or condition made or contained
                    in this Agreement or in any certificate, schedule or other
                    instrument furnished or to be furnished to NEWCO under this
                    Agreement; and

                        (ii) Litigation or other claims arising from the acts
                    or failures to act of TTCG in accordance with (A)
                    applicable federal, state or local statute, ordinance or
                    common law or (B) the terms and conditions of this
                    Agreement.

            The only exclusion from this indemnification provision is liability
            arising from grossly negligent acts of NEWCO.

                 (b) NOTICE AND DEFENSE OF CLAIMS. If requested by the TTCG or
            if the Indemnified NEWCO Party so desires, the Indemnified NEWCO
            Party shall tender the defense to TTCG of any matter for which the
            Indemnified NEWCO Party believes it is entitled to indemnification
            pursuant to Section 6.2(a) of this Agreement, in which event TTCG
            shall conduct such defense at its sole cost and thereafter be liable
            for all Damages with respect to such claim or proceeding. Such
            notice shall be given in accordance with Section 7.7 hereof.

                 If TTCG elects to assume control of such defense or settlement,
            it shall conduct such defense or settlement in a manner reasonably
            satisfactory and effective to protect the Indemnified NEWCO Party
            fully; TTCG and its counsel will keep the Indemnified NEWCO Party
            fully advised as to the conduct of such defense or settlement, and
            no compromise or settlement shall be agreed or made without the
            Indemnified NEWCO Party's written consent. In any case, the
            Indemnified NEWCO Party shall have the right to employ its own
            counsel and such counsel may participate in such action, but the
            reasonable fees and expenses of such counsel shall be at the expense
            of the Indemnified NEWCO Party, when and as incurred unless (A) the
            employment of counsel by the Indemnified NEWCO Party has been
            authorized in writing by TTCG, (B) the Indemnified NEWCO Party shall
            have reasonably concluded that there may be a conflict of interest
            between TTCG and the Indemnified NEWCO Party in the conduct of the
            defense of such action, or (C) TTCG shall not in fact have employed
            independent counsel reasonably satisfactory to the Indemnified NEWCO
            Party to assume the defense of such action and shall have been so
            notified by the Indemnified NEWCO Party. If clause (B) or (C) of the
            preceding sentence shall be applicable, then counsel for the
            Indemnified NEWCO Party shall have the right to direct the defense
            of such claim, action, suit or proceeding on behalf of the
            Indemnified NEWCO Party and the reasonable fees and disbursements of
            such counsel shall constitute Damages hereunder.

<PAGE>   63

                           The Indemnified NEWCO Party and TTCG, as the case may
                  be, shall be kept fully informed of such claim, action, suit
                  or proceeding at all stages thereof, whether or not such party
                  is represented by its own counsel.

                  6.3 COOPERATION. The parties hereto agree to render to each
         other such assistance as may reasonably be expected of each other and
         to cooperate in good faith with each other in order to insure the
         proper and adequate defense of any claim, action, suit or proceeding
         brought by any third party. Where counsel has been selected pursuant to
         Section 6.1(a) or Section 6.2(a), each party shall be entitled to rely
         on the advice of such counsel in the conduct of the defense.

                  6.4 CONFIDENTIALITY. The parties agree to cooperate in such a
         manner as to preserve and uphold the confidentiality of all
         confidential business records and the attorney-client and work-product
         privileges. In connection therewith, each party agrees (a) it will use
         its best efforts in any action, suit or proceeding in which it has
         assumed or participated in the defense to avoid production of
         confidential business records (consistent with applicable law and rules
         of procedures) and (b) all communications between any party hereto and
         counsel responsible for or participating in the defense of any action,
         suit or proceeding shall, to the extent possible, be made so as to
         preserve any applicable attorney-client or work-product privilege.

                  7. MISCELLANEOUS.

                  7.1 ASSIGNMENT. Neither party shall assign this Agreement or

         hereto constitute the entire agreement between the parties with regard
         to the subject matter herein. No oral or written agreement or practice

         supersede this Agreement.

                  7.3 AMENDMENT. None of the terms and provisions of this
         Agreement may be modified or amended in any way except by an instrument
         in writing executed by each party hereto.

                  7.4 WAIVER. Failure by either party hereto at any time to
         require performance by the other party or to claim a breach of any
         provision of this Agreement will not be construed as a waiver of any
         subsequent breach nor effect the validity and operation of this
         Agreement, nor prejudice either party with regard to any subsequent
         action.

                  7.5 NOTICES. Any notice or other communications required or
         permitted hereunder shall be sufficiently given if in writing and

         delivered personally or by wire transmission; (b) on the next business
         day after deposit with an overnight air courier; or (c) three business
         days after being sent, if sent by registered or certified mail.

                  7.6 GOVERNING LAW. This Agreement shall be interpreted and
         enforced under the laws of the State of Michigan applicable to
         contracts made and to be performed entirely within such State without
         giving effect to choice of law principles of such State. The parties
         irrevocably consent to the jurisdiction of the courts of Michigan to
         determine all issues which may arise under this Agreement.

                  7.7 SEVERABILITY. If any one or more of the provisions of this
         Agreement should be invalid, illegal or unenforceable in any respect,
         the validity, legality and enforceability of the remaining provisions
         contained herein shall not in any way be affected, impaired or
         prejudiced thereby.

                  7.8 FORCE MAJEURE. Neither party hereto shall be liable to the
         other for any loss of business or any other damages caused by an
         interruption of this Agreement whereas such interruption is due to:

         statute, order, or regulation prohibiting the performance of this
         Agreement; riots, strikes, labor stoppages, lockouts or labor disputes
         to the extent such occurrences are not caused by the actions of the
         party seeking relief under this Section; or other causes beyond the
         reasonable control of NEWCO or TTCG.

                  7.9 SUCCESSORS AND ASSIGNS. This Agreement shall be binding
         upon NEWCO and TTCG and the successors, transfers and assigns of each.

                  7.10 SECTION HEADINGS. The Section Headings of this Agreement
         are for the convenience of the parties only and in no way after,
         modify, amend, limit or restrict contractual obligations of the
         parties.

                  7.11 COUNTERPARTS. This Agreement may be executed in one or
         more counterparts, each of which shall be deemed to be an original, but
