- hereinafter referred to as Technology Company (TC) -   - dormant partner, hereinafter: tbg -
</TABLE>

                                to the amount of
                             *** DM 3,000,000.00***
                          (in words: DM three million)
            for financing the project described in (S) 1 paragraph 2

                                    Preamble

Within the framework of the programme "Investment Capital for Small Technology
Companies" carried out by the Federal Ministry of Education, Science, Research
and Technology (BMBF) and the Deutsche Ausgleichsbank, tbg supports technology
companies in the commercial business sector provided that they have not yet
existed for longer than 10 years and do not comply with the EU definition of
small companies throughout the federal territory, i.e.

     .    employ fewer than 50 members of staff

     and have either

     .    an annual sales revenue not exceeding DM 14 million

     or

     .    a balance sheet total not exceeding DM 10 million

     and

     .    are owned through a shareholding of less than 25 % by one or more
          companies not meeting this definition (except for public holding
          companies, venture capital companies and, unless control is exercised
          - institutional investors).

<PAGE>

Simultaneous compliance with all three of these basic requirements is necessary,
i.e. a company is only viewed as a small company if it has the required
independence, complies with the specifications as to the number of employees and
does not exceed at least one of the limits for the annual sales revenue or
balance sheet total.

tbg assumes participations only for the purpose of financing innovation projects
within the meaning of the Principles of Participation of tbg, which are an
integral part of this Agreement and which the TC acknowledges as follows:

     .    for pre-competitive research and development activities up to a
          logical second before starting commercial production according to the
          EU definition with the following delimitation:

          pre-competitive research includes research or experimental activities
          with the purpose of gaining new knowledge to facilitate the
          achievement of specific and practical goals such as the creation of
          new products, production methods or services. It is generally possible
          to say that they end upon the creation of a first prototype.
          Development includes work on the basis of applied research with the
          aim of introducing new or significantly improved products, production
          methods or services through to, but not only restricted to, industrial
          application and commercial use. Pilot and demonstration projects
          usually belong to this stage as well as the required continued
          development activities which finally lead to a pool of information
          which permits production to be started.

     .    for investments for the market launch.

                                      (S) 1

                             Purpose of the Company

1)   The TC entered in the Commercial Register of Muhlhausen Local Court under
     number B3706 operates a commercial enterprise according to the Articles of
     Association in the version dated 4 April 1996 for the purpose of

     the production and sale of accumulators

2)   Within the scope of the purpose of the company, the TC is involved in

     the final development and production of a lithium-polymeric solid
     accumulator

                                      (S) 2

                                  Contribution

1.   tbg shall pay a contribution amounting to DM 3,000,000.00 solely to support
     the innovation project described in (S) 1 paragraph 2 and on the basis of
     the information provided by the TC in the application for participation
     dated 16 March 1998 if the TU furnishes proof of the following partnership
     agreements:

     .    Partnership Agreement to the amount of DM 3,000,000.00 with

                                 TAMARCHCO GmbH
                                 Buchwiese 3

                                 65510 Idstein

          (hereinafter referred to as the Investor, also in case of several
          investors) and the investor with whom tbg has concluded a cooperation
          agreement

     .    Direct debit authorization to collect the fixed remuneration due by
          tbg.

2.   The contribution paid by tbg shall be used to jointly finance the
     project-related planning described in Annex I, which is an integral part of
     this Partnership Agreement. To finance the investments stated in the
     project planning for the market launch in the warehouse and stocks in hand,
     introductory advertising, personnel costs for the market launch and the
     set-up and expansion of a sales company, the TC shall receive a "de
     minimis" grant to the amount of DM 0.00 upon the conclusion of this
     Agreement. The subsidy value of all the "de minimis" grants which the TC
     receives within three years after the date of the first "de minimis" grant
     may not exceed DM 195,000. This shall not affect the possibility of the TC
     receiving funds from subsidy programmes notified by the European Commission
     irrespective of "de minimis" grants.

3.   The TC may call for the contribution after the start-up of the company (cf.
     (S) 4, paragraph 1) insofar as the immediate use thereof in accordance with
     regulations, a pro rata employment of funds in conjunction with the other
     financial resources set forth in Annex I and the entire financing of the
     innovation project are guaranteed.

     The Investor shall enclose a confirmation of the basic call conditions with
     the call.

4.   This Agreement ends if the contribution fails to be called at least
     partially by 31 January 1999 at the latest.

5.   tbg shall retain a processing fee amounting to 1.00% of the entire
     contribution as stipulated in this Agreement for the first part called.

6.   The contribution of tbg shall be managed on a separate deposit account by
     the TC. tbg is prohibited to withdraw any amounts from this account.

                        Statement of Application of Funds

The TC shall confirm that the contributed funds have been applied in accordance
with the regulations on the printed form enclosed with the letter allocating the
funds within 3 months after the expiry of the project period stated in Annex I
to this Agreement subject to an extension of this period by tbg. The statement
on the application of funds shall be presented to tbg via the Investor. Upon
request proof must be furnished to the Investor and tbg that the funds have been
applied in accordance with regulations.

If the costs entailed in the project should be reduced or further public funds
be subsequently received compared to the information provided in Annex I, tbg is
entitled to reduce its contribution at a ratio equivalent to the reduction in
the investment volume. The amount of reduction shall be retransferred to tbg
without delay.

                                      (S) 4

     application mutatis mutandis of (S) 9 (4) for the share of its contribution
     due for premature repayment.

                                      (S) 5

3.   The approvals required according to (S) 5 paragraph 2 shall be obtained
     from tbg directly.

     Approval shall be deemed given if tbg fails to declare its refusal to give
     its consent in writing within a period of 14 days after receipt of the
     notification on the measures requiring its approval according to (S) 5
     paragraph 2.

                                      (S) 6
                Right to Obtain Information and Rights of Control

1.   The TC shall report to tbg every six months, by 31 March and 30 September
     each year respectively, on the economic situation of the TC and on the
     status of the innovation project described in (S) 1 paragraph 2 as long as
     tbg does not waive such reports because the Investor simultaneously
     exercises control of the TC on behalf of tbg. In addition, tbg shall
     receive a short status report from the TC each month according to the
     enclosed Annex II and an updated business plan for the following year at
     the end of the financial year.

2.   Irrespective of whether the Investor simultaneously exercises control over
     the TC on behalf of tbg, the TC shall notify tbg directly of all measures
     going beyond customary business operations in due time.

     Furthermore, tbg is entitled to rights of control according to (S) 716
     German Civil Code. This also applies after the termination of the company
     to the extent required to examine the credit balance of assets for
     liquidation.

     Moreover, tbg is entitled to inspect all TC documents related to the
     innovation project described in (S) 1 paragraph 2 at any time. tbg may
     employ the services of third parties to discharge its rights of control.

3.   The TC shall grant rights of submission, rights to obtain information and
     rights to conduct an audit to the BMBF and to an official appointed by it
     to the same extent as to tbg. The TC declares its consent to the data
     gathered on its company and the subsidised innovation project being
     forwarded by tbg to BMBF or to an institute appointed by it for the
     scientific evaluation of the programme named in the preamble of this
     Agreement. Moreover, it declares itself willing to provide the information
     required for the scientific evaluation of the programme to the BMBF and an
     institute appointed by it directly, if necessary even after the end of the
     dormant partnership. The BMBF is entitled to pass on the data disclosed to
     it to the EU Commission to discharge its supervisory and control powers. It
     shall be ensured that TU does not suffer any damage during the preparation

<PAGE>

     and, if applicable, the publication of data on the programme.

4.   The Federal Audit Office is entitled to carry out audits on the TC
     according to (S) 91 Federal budgetary regulations [BHO]. The TC shall
     provide to the Federal Audit Office and tbg all the documents and papers
     for auditing purposes which the Federal Audit Office deems necessary; it
     shall also provide appropriate information.

                                      (S) 7
                                 Advisory Board

tbg may demand the formation of an advisory board at any time. tbg shall take
part in this advisory board taking due consideration of the amount of its
contribution. The advisory board shall advise the TC on business and technical
matters, in particular on the project described in (S) 1 paragraph 2. It has the
same rights to obtain information and rights of control to which tbg is entitled
under this Agreement.

                                      (S) 8
                   Financial Year, Annual Financial Statements

1.   The financial year of the dormant partnership corresponds to that of the TC
     ("participation year"). The financial year of the TC shall end on 31
     December each year.

2.   The TC shall prepare its annual financial statement (balance sheet, profit
     and loss account, notes) in compliance with Sections 238 - 289 of the
     German Commercial Code within six months after the expiry of the financial
     year and submit such to tbg as exemplifications bearing original signatures
     certified by an accountant or a sworn auditor.

                                      (S) 9
                             Profit and Loss Sharing

1.   tbg shall receive a minimum remuneration amounting to 6.00% p.a. for its
     contribution irrespective of the year-end results of the TC. This is due
     and payable every six months subsequently as per 31 March and 30 September
     each year.

2.   In other respects, tbg shall receive 12.00% of the generated annual net
     profits from the time the contribution is called.

     For a period in which tbg holds more than one participating interest in the
     TC, it shall only receive a total of 12 % for all the participating
     interests in addition to the respective minimum remuneration for the
     generated net profits.

     Should the TC receive additional injections of capital in the course of
     further financing rounds, tbg shall adjust its profit sharing to the
     capital ratio applicable at such time.

     This profit-sharing is payable within 2 weeks after the approval of the
     annual financial statement ((S) 8 paragraph 2).

3.   For the calculation according to paragraph 2 the annual net profit before
     consideration of the share in the profits of tbg is relevant.

<PAGE>

          a)   The following shall be added to the annual net profit:

               .    taxes on corporate income and business profits and any
                    profit-sharing bonus for directors insofar as they have
                    reduced the annual net profit shown;

               .    extraordinary expenses, if such are incurred under business
                    transactions which were carried out before the start of the
                    dormant partnership;

               .    losses incurred due to the sale or destruction of fixed
                    assets insofar as these already existed on the date of the
                    start-up of the company.

          b)   The following shall be deducted from the annual net profit:

               .    amounts gained from the retransfer of tax-free reserves
                    which were formed before the start of the dormant
                    partnership;

               .    extraordinary income if such are gained from business
                    transactions which were carried out before the start of the
                    dormant partnership;

               .    grants, bonuses and allocations by the public sector if
                    these affected net income;

               .    income from the sale of fixed assets insofar as these
                    already existed on the date of the start-up of the company.

          c)   In the year in which the participation is called, the accrual of
               the annual net profit shall be considered as evenly spread over
               the year to calculate the share in the profits according to
               paragraph 2.

4.   tbg is entitled to demand a non-recurrent remuneration of 30% of the amount
     invested plus 6% of the amount invested at the end of the period of
     participation for each year after the expiry of the fifth full year of
     participation (final remuneration). The annually paid share in the profits
     according to (S) 9 paragraph 2 shall be offset against the final
     remuneration payable. Should the total share in the profits exceed the
     final remuneration, no reimbursement shall be made.

     tbg shall only exercise this right if this appears justified in its opinion
     on the basis of the overall economic situation of the TC, in particular due
     to the profits made in the three years prior to the end of the
     participation and the hidden reserves formed during the period of
     participation.

5.   tbg shall not share in the losses of the TC.

                                     (S) 10
                                      Taxes

The TC shall attend to the remittance of the capital gains tax prescribed by law
plus the solidarity surcharge for the remuneration for the dormant holding and
withhold the capital gains tax and the solidarity surcharge from the respective
payments to tbg and pay these to the tax office responsible immediately after
these become due and payable. After remittance, the TC shall provide
certificates to tbg within the meaning of (S) 15a (3) Income Tax Act on the
printed forms provided for this purpose by tbg within 2 months after the due
date of the payments.

                     Liquidation of the Dormant Partnership

1.   In the event of the liquidation of the TC, the dormant partnership shall be
     dissolved. The dormant holding shall be repaid in such a case.

2.   (S) 9 paragraph 4 shall be applicable even in this case.

                                     (S) 12
                                   Termination

1.   The TC is entitled to dissolve the participation of tbg in whole or in part
     by observing a notice period of three months to 30 June or 31 December of
     each year. Should this dissolution take place by the end of the fifth full
     year of participation, the contribution shall be repaid to tbg with a
     premium amounting to 30.00%. From the start of the sixth year of
     participation, the provision set forth in (S) 9 paragraph 4 applies. Tbg
     may then waive payment of the premium if termination is given due to the
     discontinuance of the innovation project subsidised according to (S) 1
     paragraph 2.

2.   Should good cause exist, the dormant partnership may also be terminated
     without notice by each of its partners by submitting a written notification
     to this effect. If the contribution has not been paid at all or has not
     been paid in full, tbg shall be released from its obligation to pay the
     contribution upon submission of the notice of termination.

     tbg shall be entitled to terminate for good cause especially if

          a)   the TC has provided incorrect information in the application for
               participation

          b)   it emerges that the basic conditions for granting or retaining
               the participation were not met or the basic conditions for
               retaining the participation have ceased to apply, in particular
               that the innovation project described in (S) 1 paragraph 2 has
               proved itself to be impractical or has been discontinued by the
               TC or essentially modified. If the innovation project described
               in (S) 1 paragraph 2 has proved itself to be technical unfeasible
               or economically unviable, tbg may waive the repayment of the
               participation in whole or in part if this thereby enables the
               continued existence of the TC;

          c)   the TC fails to present the statement on the application of funds
               according to (S) 3 despite a reminder within three months after
               the due date;

          d)   bills accepted by the TC are protested, the TC stops payments, an
               application is filed for bankruptcy proceedings or an application
               is filed to open court settlement proceedings or insolvency is
               established in any other manner;

          e)   those managerial employee(s) with know-how at the TC upon
               conclusion of the agreement concerning the dormant partnership
               is/are no longer employed full-time as company manager(s) of the
               TC;

          f)   one of the measures listed in (S) 5 paragraph 2 was implemented
               without obtaining the prior consent of tbg.

<PAGE>

                                     (S) 13
                                  Payments Due

Interest at 4% p.a. shall be paid for outstanding payments from the time such
payments are delayed until receipt thereof by tbg.

                                     (S) 14
                               General Provisions

1.   Amendments and supplements to this Agreement must be made in writing. There
     are no additional verbal agreements to this Agreement.

2.   Should a provision of this Agreement be legally invalid, this shall not
     affect the remaining provisions. The TC and tbg undertake to replace
     invalid contractual provisions by provisions which are legally valid and
     most closely approximate the sense and purpose of the legally invalid
     provisions.

                                           AT&T MA REFERENCE NO. 11882
                                                                ---------------

                          GENERAL TERMS AND CONDITIONS

The following terms and conditions shall apply to the provision and use of the
products and services ("Service" or "Services") provided by AT&T pursuant to
this Agreement.

1.0      DEFINITIONS

1.1 "Affiliate" of a party means any entity that controls, is controlled by or
is under common control with such party, and, in the case of AT&T, it also means
any entity which AT&T has authorized to offer any Service or part of any
Service.

1.2 "Content" means information made available, displayed or transmitted in
connection with a Service (including, without limitation, information made
available by means of an HTML "hot link", a third party posting or similar
means) including all trademarks, service marks and domain names contained
therein as well as the contents of any bulletin boards or chat forums, and, all
updates, upgrades, modifications and other versions of any of the foregoing.

1.3 "User" means anyone who uses or accesses any Service purchased by You under
this Agreement.

2.0      CHARGES AND BILLING

2.1 You shall pay AT&T for Your and Users' use of the Services at the rates and
charges specified in the Attachments, without deduction, setoff or delay for any
reason. Charges set forth in the Attachments are exclusive of any applicable
taxes. You may be required at any time to pay a deposit if AT&T determines that
You are not creditworthy.

2.2 You shall pay all shipping charges, taxes (excluding those on AT&T's net
income) and other similar charges (and any related interest and penalties)
relating to the sale, transfer of ownership, installation, license, use or
provision of the Services, except to the extent a valid tax exemption
certificate is provided by You to AT&T prior to the delivery of Services.

2.3 Payment in U.S. currency is due within thirty (30) days after the date of
the invoice and shall refer to the invoice number. Restrictive endorsements or
other statements on checks accepted by AT&T will not apply. You shall reimburse
AT&T for all costs (including reasonable attorney fees) associated with
collecting delinquent or dishonored payments. At AT&T's option, interest charges
may be added to any past due amounts at the lower of 1.5% per month or the
maximum rate allowed by law.

3.0      RESPONSIBILITIES OF THE PARTIES

3.1 AT&T agrees to provide Services to You, subject to the availability of the
Services, in accordance with the terms and conditions, and at the charges
specified in this Agreement, consistent with all applicable laws and
regulations.

3.2 You shall assure that Your and Users' use of the Services and Content will
at all times comply with all applicable laws, regulations and written and
electronic instructions for use. AT&T reserves the right to terminate affected
Attachments, suspend affected Services, and/or remove Your or Users' Content
from the Services, if AT&T determines, in the exercise of its reasonable
discretion, that such use or Content does not conform with the requirements set
forth in this Agreement or interferes with AT&T's ability to provide Services to
You or others or receives notice from a reputable source that Your or Users' use
or Content may violate any laws or regulations. AT&T's actions or inaction under
this Section shall not constitute review or approval of Your or Users' use or
Content. AT&T will use reasonable efforts to provide notice to You before taking
action under this Section.

4.0      USE OF INFORMATION

4.1 All documentation, technical information, Software, business information, or
other materials that are disclosed by either party to the other in the course of
performing this Agreement shall be considered proprietary information
("INFORMATION") of the disclosing party, provided such information is in written
or other tangible form that is clearly marked as "proprietary" or
"confidential". This Agreement shall be deemed to be AT&T and Your INFORMATION.
Your Content shall be deemed to be Your INFORMATION.

4.2 Each party's INFORMATION shall, for a period of three (3) years following
its disclosure (except in the case of Software, for an indefinite period): (i)
be held in confidence; (ii) be used only for purposes of performing this
Agreement (including in the case of AT&T, the ability to monitor and record Your
transmissions in order to detect fraud, check quality, and to operate, maintain
and repair the Services) and using the Services; and (iii) not be disclosed
except to the receiving party's employees, agents and contractors having a
need-to-know (provided that such agents and contractors are not direct
competitors of either party and agree in writing to use and disclosure
restrictions as restrictive as this Article 4), or to the extent required by law
(provided that prompt advance notice is provided to the disclosing party to the
extent practicable).

4.3 The restrictions in this Article shall not apply to any information that:
(i) is independently developed by the receiving party; or (ii) is lawfully
received by the receiving party free of any obligation to keep it confidential;
or (iii) becomes generally available to the public other than by breach of this
Agreement.

5.0      PUBLICITY AND MARKS

5.1 No public statements or announcements relating to this Agreement shall be
issued by either party without the prior written consent of the other party.

5.2 Each party agrees not to display or use, in advertising or otherwise, any of
the other party's trade names, logos, trademarks, service marks or other indicia
of origin (collectively "Marks") without the other party's prior written
consent, provided that such consent may be revoked at any time.

6.0      SOFTWARE

6.1 AT&T grants You a personal, non-transferable and non-exclusive license
(without the right to sublicense) to use, in object code form, all software and
associated written and electronic documentation and data furnished pursuant to
the Attachments (collectively, the "Software"), solely in connection with the
Services and solely in accordance with applicable written and electronic
documentation. You will refrain from taking any steps to reverse assemble,
reverse compile or otherwise derive a source code version of the Software. The
Software shall at all times remain the sole and exclusive property of AT&T or
its suppliers. "Third-Party Software" means Software that bears a copyright
notice of a third party. "AT&T Software" means all Software other than
Third-Party Software.

6.2 You shall not copy or download the Software, except that You shall be
permitted to make two (2) copies of the Software, one for archive and the other
for disaster recovery purposes. Any copy must contain the same copyright notices
and proprietary markings as the original Software.

6.3 You shall assure that Your Users comply with the terms and conditions of
this Article 6.

6.4 The term of the license granted hereunder shall be coterminous with the
Attachment which covers the Software.

6.5 You agree to comply with any additional restrictions that are provided with
any Third-Party Software.

<PAGE>

6.6 AT&T warrants that all AT&T Software will perform substantially in
accordance with its applicable published specifications for the term of the
Attachment which covers the Software. If You return to AT&T, within such period,
any AT&T Software that does not comply with this warranty, then AT&T, at its
option, will either repair or replace the portion of the AT&T Software that does
not comply or refund any amount You prepaid for the time periods following
return of such failed or defective AT&T Software to AT&T. This warranty will
apply only if the AT&T Software is used in accordance with the terms of this
Agreement and is not altered, modified or tampered with by You or Users.

7.0      ADJUSTMENTS TO MINIMUM ANNUAL REVENUE COMMITMENTS

In the event of a business downturn beyond Your control, or a corporate
divestiture, merger, acquisition or significant restructuring or reorganization
of Your business, or network optimization using other AT&T Services, or
reduction of the rates and charges, or chronic Service failures, or force
majeure events, any of which significantly impairs your ability to meet Your
minimum annual revenue commitments under an Attachment, AT&T will offer to
adjust the affected minimum annual revenue commitments so as to reflect Your
reduced traffic volumes, after taking into account the effect of such a
reduction on AT&T's costs and the AT&T prices that would otherwise be available
at the revised minimum annual revenue commitment levels. If we reach mutual
agreement on revised minimum annual revenue commitments, we will amend or
replace the affected Attachment, as applicable. This provision shall not apply
to a change resulting from a decision by You to transfer portions of Your
traffic or projected growth to service providers other than AT&T. You must give
AT&T written notice of the conditions You believe will require the application
of this provision. This provision does not constitute a waiver of any charges,
including, but not limited to, monthly recurring charges and shortfall charges,
incurred by You prior to amendment or replacement of the affected Attachment.

8.0      FORCE MAJEURE

Neither AT&T nor You shall be liable for any delay, failure in performance, loss
or damage due to: fire, explosion, power blackout, earthquake, flood, the
elements, strike, embargo, labor disputes, acts of civil or military authority,
war, acts of God, acts or omissions of carriers or suppliers, acts of regulatory
or governmental agencies, or other causes beyond such party's reasonable
control, whether or not similar to the foregoing, except that Your obligation to
pay for charges incurred for Services received by You shall not be excused.

9.0      LIMITATIONS OF LIABILITY

9.1 For purposes of all exclusive remedies and limitations of liability set
forth in this Agreement or any Attachment, "AT&T" shall be defined as AT&T, its
Affiliates, and its and their employees, directors, officers, agents,
representatives, subcontractors, interconnection service providers and
suppliers; and "You" shall be defined as You, Your Affiliates, and Your and
their employees, directors, officers, agents, and representatives; and "Damages"
will refer collectively to all injury, damage, liability, loss, penalty,
interest and expense incurred.

9.2 EITHER PARTY'S ENTIRE LIABILITY AND THE OTHER PARTY'S EXCLUSIVE REMEDIES,
FOR ANY DAMAGES CAUSED BY ANY SERVICE DEFECT OR FAILURE, OR FOR OTHER CLAIMS
ARISING IN CONNECTION WITH ANY SERVICE OR OBLIGATIONS UNDER THIS AGREEMENT SHALL
BE:

(i) FOR BODILY INJURY OR DEATH TO ANY PERSON, OR REAL OR TANGIBLE PROPERTY
DAMAGE, NEGLIGENTLY CAUSED BY A PARTY, OR DAMAGES ARISING FROM THE WILLFUL
MISCONDUCT OF A PARTY OR ANY BREACH OF ARTICLES 4 OR 5, THE OTHER PARTY'S RIGHT
TO PROVEN DIRECT DAMAGES;

(ii) FOR DEFECTS OR FAILURES OF SOFTWARE, THE REMEDIES SET FORTH IN SECTION 6.6;

(iii) FOR INTELLECTUAL PROPERTY INFRINGEMENT, THE REMEDIES SET FORTH IN ARTICLE
11;

(iv) FOR DAMAGES OTHER THAN THOSE SET FORTH ABOVE AND NOT EXCLUDED UNDER
THIS AGREEMENT, EACH PARTY'S LIABILITY SHALL BE LIMITED TO PROVEN DIRECT DAMAGES
NOT TO EXCEED PER CLAIM (OR IN THE AGGREGATE DURING ANY TWELVE (12) MONTH
PERIOD) AN AMOUNT EQUAL TO THE TOTAL NET PAYMENTS MADE BY YOU FOR THE AFFECTED
SERVICE DURING THE THREE (3) MONTHS PRECEDING THE MONTH IN WHICH THE DAMAGE
OCCURRED. THIS SHALL NOT LIMIT YOUR RESPONSIBILITY FOR THE PAYMENT OF ALL
PROPERLY DUE CHARGES UNDER THIS AGREEMENT.

9.3 EXCEPT FOR THE PARTIES' ARTICLE 11 OBLIGATIONS, NEITHER PARTY SHALL BE
LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE,
RELIANCE OR SPECIAL DAMAGES, INCLUDING WITHOUT LIMITATION, DAMAGES FOR LOST
PROFITS, ADVANTAGE, SAVINGS OR REVENUES OF ANY KIND OR INCREASED COST OF
OPERATIONS.

9.4 AT&T ALSO SHALL NOT BE LIABLE FOR ANY DAMAGES ARISING OUT OF OR RELATING TO:
INTEROPERABILITY, ACCESS OR INTERCONNECTION OF THE SERVICES WITH APPLICATIONS,
EQUIPMENT, SERVICES, CONTENT OR NETWORKS PROVIDED BY YOU OR THIRD PARTIES;
SERVICE INTERRUPTIONS (EXCEPT WHERE A CREDIT IS EXPLICITLY SET FORTH IN AN
ATTACHMENT OR SERVICE GUIDE) OR LOST OR ALTERED MESSAGES OR TRANSMISSIONS; OR,
UNAUTHORIZED ACCESS TO OR THEFT, ALTERATION, LOSS OR DESTRUCTION OF YOUR, USERS'
OR THIRD PARTIES' APPLICATIONS, CONTENT, DATA, PROGRAMS, INFORMATION, NETWORK OR
SYSTEMS.

9.5 EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, AT&T MAKES NO WARRANTIES,
EXPRESS OR IMPLIED, AND SPECIFICALLY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, TITLE OR NON-INFRINGEMENT OR ANY WARRANTY
ARISING BY USAGE OF TRADE, COURSE OF DEALING OR COURSE OF PERFORMANCE.

9.6 THE LIMITATIONS OF LIABILITY SET FORTH IN THIS AGREEMENT SHALL APPLY: (i)
REGARDLESS OF THE FORM OF ACTION, WHETHER IN CONTRACT, TORT, STRICT LIABILITY OR
OTHERWISE; AND (ii) WHETHER OR NOT DAMAGES WERE FORESEEABLE. THESE LIMITATIONS
OF LIABILITY SHALL SURVIVE FAILURE OF ANY EXCLUSIVE REMEDIES PROVIDED IN THIS
AGREEMENT.

10.0     TERMINATION

10.1 If a party fails to perform or observe any material term or condition of
this Agreement and the failure continues unremedied for thirty (30) days after
receipt of written notice, (i) the other party may terminate for cause any
Attachment affected by the breach, or (ii) where the failure is a non-payment by
You of any charge when due, AT&T may, at its option, terminate or suspend
Service and/or require a deposit under affected Attachments.

10.2 An Attachment may be terminated immediately upon written notice by: (i)
either party if the other party has violated the other party's Marks, becomes
insolvent or involved in a liquidation or termination of its business, files a
bankruptcy

<PAGE>

petition, has an involuntary bankruptcy petition filed against it (if not
dismissed within thirty (30) days of filing), becomes adjudicated bankrupt, or
becomes involved in an assignment for the benefit of its creditors; or (ii)
either party due to a material breach of any provision of Article 4.

10.3 You shall be responsible for payment of all charges under a terminated
Attachment incurred as of the effective date of termination. You shall also be
liable to AT&T for Termination Charges, if specified in a terminated Attachment,
in the event that AT&T terminates under Section 10.1 or 10.2, or You terminate
without cause.

10.4 Termination by either party of an Attachment does not waive any other
rights or remedies it may have under this Agreement. Termination or suspension
of an Attachment shall not affect the rights and obligations of the parties
under any other Attachment.

11.0     FURTHER RESPONSIBILITIES

11.1 AT&T agrees to defend or settle any claim against You and to pay all
Damages that a court may award against You in any suit that alleges a Service
infringes any patent, trademark, copyright or trade secret, except where the
claim or suit arises out of or results from: Your or User's Content;
modifications to the Service or combinations of the Service with other services
or products, by You or others; AT&T's adherence to Your written requirements;
or, use of the Service in violation of this Agreement. You agree to defend or
settle any claim against AT&T and to pay all Damages that a court may award
against AT&T in any suit that alleges a Service infringes any patent, trademark,
copyright or trade secret, due to any of the exceptions in the preceding
sentence.

11.2 Whenever AT&T is responsible under Section 11.1, AT&T may at its option
either procure the right for You to continue using, or may replace or modify the
alleged infringing Service so that the Service becomes noninfringing, but if
those alternatives are not reasonably achievable, AT&T may terminate the
affected Attachment without liability other than as stated in Section 11.1.

11.3 AT&T grants to You the right to permit Users to access and use the
Services, provided that You shall remain solely responsible for such access and
use. You shall defend, indemnify and hold harmless AT&T from and against all
Damages arising out of third party claims relating to Your or Users' use of the
Service or Content or performance of the Service.

11.4 The indemnified party under this Article 11: (i) must notify the other
party in writing promptly upon learning of any claim or suit for which
indemnification may be sought, provided that failure to do so shall have no
effect except to the extent the other party is prejudiced thereby; (ii) shall
have the right to participate in such defense or settlement with its own counsel
and at its sole expense, but the other party shall have control of the defense
or settlement; and (iii) shall reasonably cooperate with the defense.

12.0     GENERAL PROVISIONS

12.1 Any supplement, modification or waiver of any provision of this Agreement
must be in writing and signed by authorized representatives of both parties. A
waiver by either party of any breach of this Agreement shall not operate as a
waiver of any other breach of this Agreement.

12.2 This Agreement may not be assigned by either party without the prior
written consent of the other, except that either party may, without the other
party's consent, assign this Agreement or any Attachment to a present or future
Affiliate or successor, provided that any such assignment by You shall be
contingent upon AT&T determining the assignee to be creditworthy and in
compliance with any eligibility criteria for the Services. AT&T may subcontract
work to be performed under this Agreement, but shall retain responsibility for
all such work.

12.3 If any portion of this Agreement is found to be invalid or unenforceable,
the remaining provisions shall remain in effect and the parties shall promptly
negotiate to replace invalid or unenforceable portions that are essential parts
of this Agreement.

12.4 Any legal action arising in connection with this Agreement must begin
within two (2) years after the cause of action arises.

12.5 All required notices under this Agreement shall be in writing and either
mailed by certified or registered mail, postage prepaid return receipt
requested, sent by express courier or hand delivered and addressed to each party
at the address set forth on the cover page of this Agreement or, if the notice
relates to a specific Attachment, the address set forth in such Attachment, or
such other address that a party indicates in writing.

12.6 State law issues concerning construction, interpretation and performance of
this Agreement shall be governed by the substantive law of the State of New
York, excluding its choice of law rules. The United Nations Convention on
Contracts for International Sale of Goods shall not apply.

12.7 This Agreement does not provide any third party (including Users) with any
remedy, claim, liability, reimbursement, cause of action or other right or
privilege.

12.8 The respective obligations of You and AT&T, which by their nature would
continue beyond the termination or expiration of any Attachment or this
Agreement, including, without limitation, the obligations regarding Use of
Information, Publicity and Marks, Further Responsibilities and Limitations of
Liability, shall survive termination or expiration.

12.9 THIS AGREEMENT CONSTITUTES THE ENTIRE AGREEMENT BETWEEN THE PARTIES WITH
RESPECT TO THE SERVICES. THIS AGREEMENT SUPERSEDES ALL PRIOR AGREEMENTS,
PROPOSALS, REPRESENTATIONS, STATEMENTS OR UNDERSTANDINGS, WHETHER WRITTEN OR
ORAL CONCERNING THE SERVICES, OR THE RIGHTS AND OBLIGATIONS RELATING TO THE
SERVICES. THIS AGREEMENT SHALL NOT BE CONTRADICTED, OR SUPPLEMENTED BY ANY
WRITTEN OR ORAL STATEMENTS, PROPOSALS, REPRESENTATIONS, ADVERTISEMENTS, SERVICE
DESCRIPTIONS OR YOUR PURCHASE ORDER FORMS NOT EXPRESSLY SET FORTH IN THIS
AGREEMENT OR AN ATTACHMENT.

                                MASTER AGREEMENT

This is the Addendum to the Master Agreement by and between CORAM, INC.
("CUSTOMER", "You", or "Your"), a DELAWARE corporation having a principal place
of business at 1675 BROADWAY, SUITE 900, DENVER, CO, 80202 and AT&T Corp., a New
York corporation ("AT&T"), with offices at 55 Corporate Drive, Bridgewater, NJ
08807, on behalf of itself and its Affiliates.

CUSTOMER and AT&T hereby agree to the following modifications to the General
Terms and Conditions of the Master Agreement:

         1. ARTICLE 10.0 - TERMINATION

         SECTION 10.2 is modified by adding the following at the end of
         10.2.(i):

         The parties acknowledge and agree that as of the date of execution of
         this Agreement, Customer has filed a petition for protection under
         Chapter 11 of the United States Bankruptcy Code. Notwithstanding that,
         as of the date of execution of the Agreement, Customer is in
         bankruptcy, AT&T will not terminate this Agreement as a consequence of
         such bankruptcy; provided that AT&T does not waive any rights under
         this Agreement, including any right to terminate the Agreement upon the
         happening of any subsequent event that would give rise to such right or
         rights of termination, including without limitation, any subsequent
         bankruptcy filing of Customer.

Except as modified herein, the terms of the Master Agreement remain unchanged
and in full force and effect.

IN WITNESS WHEREOF, AT&T and CUSTOMER have caused this Addendum to be executed
by their duly authorized representatives.
