liabilities of Sellers under the Purchased Contracts  and the employment
contracts listed on Schedule 1.02 hereto (collectively, the "Assumed
                    -------------
Liabilities").

     1.03. Excluded Liabilities.  Other than as set forth in Section 1.02
           --------------------
hereto, the parties hereto expressly agree that each of Sellers shall retain,
and Buyer shall not assume, and nothing contained in this Agreement shall be
construed as an assumption by Buyer of, any liabilities, obligations or
undertakings of either of Sellers, related to the Assets or otherwise, of any
nature whatsoever, whether accrued, absolute, fixed or contingent, known or
unknown due or to become due, unliquidated or otherwise.

     1.04  Purchase Price.  The aggregate purchase price (the "Purchase Price")
           --------------
to be paid by Buyer to Sellers for the Assets shall be (i) the "Base Price, " as
defined in Section 1.05 hereof, and (ii) the "Contingent Price," as defined in

     1.05  Base Price.  The portion of the Purchase Price that is payable, at
           ----------
the Closing and on each of three "Anniversary Payment Dates," as defined below
(the "Base Price"), is as follows:

           (a) Stock Consideration.  At the Closing, Buyer shall transfer to
Sellers or Sellers' assigns shares of its common stock, Nasdaq symbol TESI (the
"Buyer Common Stock") in the amount of 3,000,000 shares (the "Stock
Consideration").  The Stock

                                       4
<PAGE>

Consideration shall be payable, in the manner set forth in Section 1.07 hereof,
in fully paid, nonassessable shares of Buyer Common Stock, issued without
registration under the Securities Act of 1933 pursuant to an exemption
therefrom, and transfer shall be restricted as provided by Section 3.10. The
Stock Consideration shall be delivered free of any liens, security interests or
encumbrances arising by or through Buyer, except for the transfer restrictions
referred to in Section 3.10.

          (b)  Cash Consideration.  Buyer shall pay to Sellers cash in the
aggregate amount of $1,500,000 (the "Cash Consideration"), payable, in the
manner set forth in Section 1.07 hereof, in three installments (each an "Annual
Cash Payment") due, respectively, on each of the first three anniversaries of
the Closing Date (each of such three dates an "Anniversary Payment Date"), as
follows:  (1) an Annual Cash Payment of $300,000 on the first Anniversary
Payment Date; (2) an Annual Cash Payment of $500,000 on the second Anniversary
Payment Date; and (3) and an Annual Cash Payment of $700,000 on the third
Anniversary Payment Date.  With respect to the first Annual Cash Payment, Buyer
may elect to provide, in lieu of cash, a number of shares of Buyer Common Stock
equivalent in aggregate value to the amount of such Annual Cash Payment, the
value of each such share to be deemed equal to 80% of the average NASDAQ closing
price during the 20 trading days immediately prior to the relevant Anniversary
Payment Date (the "Optional Annual Stock Payment").

     1.06  Contingent Price.  In addition to the Base Price, Buyer shall pay to
           ----------------
Sellers, in the manner set forth in Section 1.07 hereof, an additional,
contingent amount (the "Contingent Price") in the form of an earnout (the
"Earnout"), but only if and to the extent Buyer is obligated to pay such Earnout
pursuant to the following procedures:

                                       5
<PAGE>

          (a)  The Earnout shall be payable in a maximum of three annual
payments (each an "Earnout Payment"), each due, respectively, 15 days after an
Anniversary Payment Date; provided, however, that no Earnout Payment shall be
                          --------  -------
due and payable on the respective Anniversary Payment Date unless the revenues
for products and services related to the Assets, or products and services
resulting from technology derived from the Assets (collectively, "Asset-Related
Revenues") generated during the 12-month period ending on each such Anniversary
Payment Date exceed, the following target amounts (each a "Target Revenue
Amount"): (i) $3,000,000, prior to the first Anniversary Payment Date; (ii)
$5,000,000, between the first and second Anniversary Payment Date, and (iii)
$7,000,000, between the second and third Anniversary Payment Date.

          Excluded from the provisions of Section 1.06(a) are revenues derived
from additional products/enhancements created due to Buyers additional
investments and development, for which license and periodic maintenance fees are
charged in addition to those normally charged present customers for the Asset-
Related products and services, and which are not incremental adjustments to
Asset-Related revenues for product and service fees.

          (b)  In the event the Asset-Related Revenues exceed the Target Revenue
Amount with respect to a particular Anniversary Payment Date, an Earnout Payment
shall be due and payable by Buyer in an amount equal to the lesser of (i) 5% of
the portion of such Asset-Related Revenues in excess of such Target Revenue
Amount or (ii) $300,000, with respect to the first Anniversary Payment Date,
$500,000, with respect to the second Anniversary Payment Date, and $700,000,
with respect to the third Anniversary Payment Date.  The Earnout Payments are to
be computed independently, such that any or all of the three Earnout Payments
may or may not be paid, depending on achievement of the specified level of Asset
Related

                                       6
<PAGE>

Revenues for the relevant periods. However, if the average of the daily NASDAQ
closing prices of a share of Buyer Common Stock during the last 20 consecutive
trading days immediately prior to any Anniversary Payment Date upon which an
Earnout Payment is due and payable exceeds $2.00 per share, the Earnout Payment
percentage shall be reduced by 1% for each $1.00 increase in the stock price
above $2.00 per share (e.g. the Earnout Payment percentage would be reduced from
5% to 3% if the Buyer Common Stock price were $4.00 per share and 0% if the
Buyer Common Stock price were $7.00 per share).

     1.07  Manner of Payment; Escrow Fund.  On the Closing Date Buyer shall
           ------------------------------
deliver the Stock Consideration to an escrow agent (the "Escrow Agent") to be
held in escrow (the "Escrow Fund") for a period of 24 months after the Closing
Date pursuant to the terms of an escrow agreement to be executed by the parties
at the Closing (the "Escrow Agreement").  If at the first Anniversary Date the
equivalent publicly traded market value of the shares of Stock Consideration
held in the Escrow Fund is less than $4,000,000, and Buyer elects to provide
shares of Buyer Common Stock in lieu of the first Annual Cash Payment of
$300,000, Buyer may elect to place such stock in the Escrow Fund. The Escrow
Fund shall be subject to utilization as set forth in Section 6.01 hereof.
Releases of amounts from the Escrow Fund by the Escrow Agent shall be allowed
only as follows:

          (a)  300,000 shares of Buyer Common Stock shall be released pursuant
to Schedule 1.07(a) hereto on the first business day following the last day of
   ----------------
the twelve-month period commencing on the Closing Date, provided that there
                                                        --------
shall not have occurred any indemnifiable loss or losses, in an aggregate amount
exceeding the Threshold Claim Amount (as defined in Section 6.02 hereof), for
which Sellers have not fully indemnified Buyer.

                                       7
<PAGE>

          (b)  The balance of the Escrow Fund shall be released to Sellers on
the first business day following the earlier to occur of the following:

               (i)    the date of delivery by Sellers to Buyer of a guaranty in
     favor of Buyer, guaranteeing Sellers' Obligations (as defined in Section
     6.01 hereof), which guaranty either shall be supported by a letter of
     credit in an amount equal to the Maximum Indemnification Amount (as defined
     in Section 6.02 hereof), drawn on a United States bank reasonably
     acceptable to Buyer, or shall be another form of guaranty acceptable to
     Buyer; or
               (ii)   the last day of the 24-month period commencing on the
     Closing Date, unless Buyer objects in writing prior to such release based
     on the evidence of an indemnifiable loss or losses, in an aggregate amount
     exceeding the Threshold Claim Amount, for which Sellers have not fully
     indemnified Buyer.

          (c)  On each Anniversary Payment Date, if the market value of a number
of publicly traded shares of Buyer Common Stock equal to the number of such
shares held in the Escrow Fund (based on the average of the daily NASDAQ closing
prices of a share of Buyer Common Stock during the last 20 consecutive trading
days immediately prior to any Anniversary Payment Date), is greater than 125% of
$4,000,000, the number of such shares in excess of the number whose equivalent
value equals 125% of $4,000,000 will be released from the Escrow Fund to Seller
within 10 business days of such Anniversary Date.

          (d)  The balance of the Escrow Fund or any portion thereof may be
released to Sellers

               (i)  upon and according to the joint written instructions of both
     Buyer and Sellers or

                                       8
<PAGE>

               (ii) otherwise by the Escrow Agent in accordance with the Escrow
     Agreement.

Sellers, jointly, on the one hand, and Buyer, on the other, shall share equally
all costs related to the establishment and maintenance of the Escrow Fund, as
provided in the Escrow Agreement.

     1.08 Allocation of Purchase Price.  Buyer and Sellers have mutually agreed
          ----------------------------
to allocate the Purchase Price among the Assets in the manner set forth in
Schedule 1.08 hereto, after taking into account the applicable treasury

forgoing, each of Sellers specifically represents and warrants that its title to
such Assets is free and clear of all liens and encumbrances held by any
subsidiary of either of Sellers, Dana Commercial Credit Corporation, a Delaware
corporation, or any other entity.

     3.07  No Tax Liens.  There are no liens for Taxes upon any of the Assets,
           ------------
except liens for Taxes not yet due.  For purposes of this Agreement, the term
"Taxes" means all federal, state, local or foreign taxes, charges, fees, levies,
or other assessments, including, without limitation, all net income, gross
income, gross receipts, sales, use, ad valorem, transfer, franchise, profits,
license, withholding, payroll, employment, social security, unemployment,
excise, estimated, severance, stamp, occupation, property, or other taxes,
customs duties, fees, assessments, or charges of any kind whatsoever.

True and correct copies of the Purchased Contracts have been made available to
Buyer.  Each of the Purchased Contracts is in full force and effect as of the
date hereof, constitutes binding obligations of each party thereto, and is valid
and enforceable in accordance with its terms.  To Sellers knowledge, neither of
Sellers nor any other party is in default under the terms of any of the
Purchased Contracts, and there exists no occurrence, event, condition or act
which, upon the giving of notice or the lapse of

                                       14
<PAGE>

time or otherwise, would likely become such a default. Except for any notices
relating to disputes with respect to purported amendment to the EAMS
Distribution Agreement (as defined in Section 6.01 hereof), neither of Sellers
has given to or received from any other individual or entity any notice or other
communication, whether oral or written, regarding any actual, alleged, possible
or potential violation or breach of, or default under, any of the Purchased
Contracts. None of the Purchased Contracts (a) is subject to cancellation or
termination upon the sale of the Assets to Buyer or (b) requires the consent of
a third party prior to the transfer thereof. Sellers expressly acknowledge their
liability for disputes relating to purported amendments to the EAMS Distribution
Agreement.

an allegation;

          (e) Neither of Sellers has granted any other person or entity any
rights (ownership, revenue-sharing or otherwise) with respect to any of the
Intellectual Property; and

          (f) to the actual knowledge of Sellers,  no person is using any
intellectual property that is confusingly similar to, which infringes upon, or
which violates Sellers' rights with respect to the Intellectual Property.

     3.10. Investment Intent; Legend on Shares.  Each of Sellers hereby
           -----------------------------------
represents and warrants as follows:

           (a) Sellers are acquiring the Stock Consideration for their own
account and not with a view to distribution thereof within the meaning of
Section 2(11) of the Securities Act of 1933 (the "Securities Act").  None of the
Stock Consideration will be registered under the Securities Act or the
securities laws of any state and each Seller agrees that none of such restricted
shares will be sold (or pledged, assigned or otherwise disposed, except pursuant
to the Escrow Agreement) or offered for sale without registration under the
Securities Act or the availability of an exemption therefrom or in violation of
any other law, statute, regulation or other legal requirement of the United
States of America or any state political subdivision thereof.  Each Seller
further understands and agrees that Buyer is not obligated to honor any attempt
by it to sell, pledge, transfer or otherwise dispose of any such shares of Buyer
Common Stock in the absence of an effective registration statement for such
shares under the Securities Act and applicable state securities laws or an
opinion of counsel, provided at the expense of Sellers and satisfactory in form
and substance to Buyer and their counsel, that an exemption from registration is
available.  As a consequence of the foregoing, Buyer shall have the right (at
its discretion) to cause any certificate evidencing shares of Buyer Common Stock
constituting Stock Consideration to bear the following legends in substantially
the following form:

          The shares represented by this certificate have not
          been registered under the Securities Act of 1933, as
          amended (the "1933 Act"), or the securities laws of any
          state. The shares may not be sold, transferred, pledged
          or hypothecated in the absence of any effective
          registration statement under the 1933 Act and such

                                       17
<PAGE>

          registration or qualification as may be necessary under
          the securities laws of any jurisdiction, or an opinion
          of counsel satisfactory to Tangram Enterprise
          Solutions, Inc. that such registration or qualification
          is not required.

          (b) On request of Sellers, Buyer will use best efforts to promptly
cause the legend to be removed once the underlying shares of Buyer Common Stock
are no longer subject to such share transfer restrictions and such removal, in
the opinion of Buyer's counsel, is no longer required under applicable legal
requirements.

          (c) Each Seller further represents and warrants to Buyer that:

              (i)   it has been furnished and has carefully read the information
contained in this Agreement, the Schedules hereto, the documents referred to
herein and in the Schedules hereto, and the reports filed by Buyer with the
Securities and Exchange Commission under the Securities Exchange Act of 1934
(the "Reports") previously delivered to it;

              (ii)  it has been provided an opportunity to obtain additional
information concerning Buyer, the Buyer Common Stock and any other relevant
matters;
              (iii) it has been given the opportunity to ask questions of, and
receive answers from, knowledgeable representatives of Buyer concerning Buyer
and the Buyer Common Stock.

     3.11 Litigation.  There are no actions, suits, proceedings, orders or
          -----------
investigations pending or, to the best knowledge of Sellers, threatened against
either of Sellers, at law or in equity, or before or by any federal, state,
municipal or other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, which if adversely

                                       18
<PAGE>

determined against such Seller would have a material adverse effect on such
Seller's ability to consummate the transactions contemplated in this Agreement.
Neither of Sellers is subject to any order, consent decree, settlement or other
similar written agreement of or with, or pending, to the knowledge of such
Seller, any federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign, or
any judgment, order, writ, injunction, decree or award of any federal, state or
municipal regulatory agency or arbitrator.

     3.12  Insurance. Sellers have at all times maintained insurance relating to
           ---------
the Assets and covering property, fire, casualty, liability, life, worker's
compensation, and all other forms of insurance customarily obtained by

     3.13  Permits. Sellers have, in full force and effect, all licenses,
           -------
permits and certificates, from federal, state, local and foreign authorities
necessary to conduct the business of Sellers related to the Assets
(collectively, the "Permits"). A true, correct and complete list of all the
Permits is set forth under the caption referencing this Section in Sellers'
Disclosure Schedule. Sellers have conducted the business related to the Assets
in compliance with all material terms and conditions of the Permits.

     3.14  Disclosure. No representation or warranty by Sellers contained in
           ----------
this Agreement or in Sellers' Disclosure Schedule, or any certificate or other
instrument referred to herein contains or will contain any untrue statement of a
material fact or omits or will omit to state any material fact which is
necessary in order to make the statements contained herein or therein, not
misleading. There is no fact known to Sellers relating to the Assets or to the
business, affairs, operations, or condition of Sellers that materially adversely
affects the Assets and which has not been disclosed to Buyer by Sellers.

                              Disclosure Schedule


          Except as disclosed below, Sellers offer no other disclosures as
exceptions to the representations and warranties contained in Article III of the
Asset Purchase Agreement.

Section 3.02 No Breach:

     There are outstanding notes or commitments with Dana Commercial Credit
     Corporation, the original vendor of Wyzdom to Axial that could be
     accelerated or considered breached by DCCC.

Section 3.05  Absence of Undisclosed Liabilities:

     (a)  According to Deloitte & Touche Auditor's report for year ended
          December 31, 1999 for ATH " In our opinion, the accounting records,
          the financial statements and the proposed appropriation of available
          earnings comply with the law and company's articles of incorporation,
          ...". Since ATH financials are prepared to comply with Swiss law,
          Seller cannot represent that Swiss law and GAAP are identical.

     (b)  Version 6.0 of Wyzdom contains software licensed from ChiMu
          Corporation. A Software License Agreement dated November 1, 1997 was
          executed by DCCC and sent to ChiMu, but the signed agreement was never
          signed by ChiMu. Subsequently the ChiMu software has been removed from
          Wyzdom, and future releases after V6.0 will not include it.

     (c)  There are letters dated 1 November, 2000, 6 February, 2001 and 7
          February, 2001 from Axial to EAMS, which have been provided to
          Tangram. Sellers shall remain liable for disputes arising from these
          letters.

Section 3.06  Title to Assets:

     A letter from DCCC dated 26 January 2001 confirms to Axial that "DCCC holds
     no further rights or claims to Wyzdom software", and there are no other
     liens or security interests.

               Term Sheet attached to the Letter of Understanding


                            TANGRAM-AXIAL TERM SHEET


1.   "Tangram" agrees to acquire, and "Axial" (collectively Axial Technology
     Holding AG plus Axial Investments and Trading Limited plus Wyzdom Solutions
     Inc. or their respective assignees) agree to sell to Tangram, free and
     clear of all liens and encumbrances, the following assets owned by Axial:

     a.   All rights of ownership to the Axial proprietary asset management
        technology commonly known as Wyzdom

     b.   All source code, and all documentation and tools developed to create,
        implement and support Wyzdom and related products and services

     c.   All intellectual property trademarks, copyrights, naming rights,
        domains and patents related to Wyzdom and related products and services.

     d.   All license and distribution agreements for Wyzdom products and
        related services.

     e.   All support contracts for Wyzdom products and services.

     f.   All client and prospect lists, databases, and related proprietary
        marketing and sales information for Wyzdom products and services.

     g.   All marketing, Sales, Implementation Customer Support, and Training
        documentation, together with all processes and procedures, related to
        Wyzdom products.

2.  Tangram agrees to pay Axial the following compensation for the assets
    defined in Item 1 by the following three steps.

                                       45
<PAGE>

a.   Tangram common stock (Nasdaq symbol TESI) - 3,000,000 shares at closing,
   provided the outstanding stock pre-closing is less than 17 million shares.
   Tangram shall deliver 1,500,000 shares at closing and escrow 1,500,000 shares
   to secure Axial's indemnification of Tangram with regard to any breach of the
   representations and warranties given by Axial in the definitive agreement.
   Absent an indemnifiable event the escrowed shares shall be delivered six
   months following closing or the Tangram/Wyzdom -Asset Management product
   launch date, whichever comes first. Axial has the right to renegotiate or
   decline if the closing price average of the prior five trading days before
   closing is below $0.25 per share, and Tangram has similar right to
   renegotiate or decline if the closing price average of the five trading days
   before closing is greater than $1.00 per share.

b.   Cash in the amount of $1,500,000, payable during the three years after
   closing as follows:

   . End of 12/th/ month - $300,000 USD, with Tangram having the option to
     provide Tangram common stock in lieu of cash, with the per share price
     computed at 80% of the average market closing price during the 10 trading
     days preceding the end of month 12.

   . End of 24/th/ month - $500,000 USD

   . End of 36/th/ month - $700,000 USD

c. An upside cash bonus, payable during the three years after closing, provided
   the revenue generated for asset management products and services in aggregate
   exceeded $3 million during first 12 months, $5 million during second 12
   months, and $7 million during third 12 months. When revenues exceed these
   baseline amounts during each respective 12 month

                                       46
<PAGE>

   period, Axial will earn a 5% cash bonus on asset management revenue in excess
   of the agreed baseline amounts up to a limit of an additional $300,000,
   $500,000, and $700,000 over and above the amounts specified in item 2b above
   computed through end of month 12, 24, and 36 respectively. The upside cash
   bonuses are to be computed independently, such that any or all of the 3
   bonuses may or may not be paid depending upon the achievement of the revenue
   goal for any one period. However, if the Tangram common stock price exceeds
   an average price of $2.00 per share (computed based on the average of the
   closing prices during the last month of each of the 12 month periods), the
   cash bonus is reduced 1.0% for each $1.00 increase in stock price above
   $2.00, up to a limit of $7.00. (e.g. If the average stock price is $4, the
   bonus is reduced to 3%; If the limit is reached -$7 or above for any defined
   12 month period, the bonus is reduced to 0%.)

3. Axial agrees that Tangram may enter into employment negotiations with key
   people currently employed by Wyzdom Solutions. A prerequisite to closing
   shall be Tangram having employed sufficient Wyzdom employees to transfer to
   Tangram the necessary domain expertise. If closing does not occur, Tangram
   agrees not to employ them during the following 12 months without the consent
   of Axial.

4. Axial agrees to work diligently with Tangram to determine strong incentives
   for key people from Wyzdom Solutions that become Tangram employees, such that
   there is incentive through Axial as well as through Tangram for mutual
   success by all parties for a period of twelve months following closing.

5. Axial shall be entitled to one board seat of Tangram as long as Axial has
   outstanding earn-out entitlement and/or collectively holds greater than 10%
   of the ordinary issued stock of TESI. Thomas R. Brown, or another qualified
   officer of Axial or its holding company, will become

                                       47
<PAGE>

   a member of the Board of Directors of Tangram upon closing. His initial term
   will be one year, and he will be provided all voting rights and privileges as
   normally granted to other outside directors.

6. Axial and Tangram will enter into a set of business licenses and other
   agreements at closing:

   a.   Axial will be granted a perpetual, non-exclusive, no-cost license, plus
      source and object code software, for the most current version by Wyzdom at
      the time of closing for use within the business of Axial. This license
      does not allow for sale or lease of Wyzdom to other end users or
      distributors but does envisage the use of Wyzdom for the provision of
      hosted asset management services by Axial as part of its business
      offerings.

   b.   Axial will enter into agreement and will pay normal product maintenance
      fees for future Tangram product upgrades at the most favored client rate.
      During the efficacy of the agreement, Axial will be provided the product
      upgrades to Wyzdom, or its successor product created by Tangram. In
      addition, source code upgrades will be provided under same conditions as
      item 6.a.

   c.   Axial will be able to acquire other Tangram products and support at most
      favored distributor rate for its internal use.

   d.   Where Axial's business needs special features for the Wyzdom/Tangram
      product, upon reasonable notice Tangram agrees to provide custom technical
      support at their most favored client rates. When Axial pays for such
      features, Tangram agrees to provide *Axial exclusive use of such special
      features for six months after acceptable delivery to Axial. Tangram
      retains the ownership and right to use such features in their products
      thereafter at Tangram's option.

                                       48
<PAGE>

e.    Axial and Tangram agree to negotiate a separate distribution agreement
      whereby Axial may serve as a distributor or similar value function for
      Tangram in Europe and Africa, to the extent such an agreement will not be
      competitive with existing sales channels.

7. Wyzdom Solution Inc's capital equipment and building lease are not included
   as part of the consideration paid by Tangram in Item 2. However, if Tangram
   desires any such equipment prior to closing that is not already sold to
   others, Axial agrees to sell it to Tangram at Axial's then book value.

8. Closing is scheduled for on or before 31 January 2001, and will require
   approval of the board of directors of Axial and Tangram as well as of all
   applicable regulatory authorities prior to closing. Time is of the essence.

9. No public announcement regarding this transaction will be made by either
   party without the prior approval of Tangram's or Axial's legal counsel.
