solely in connection with the use of an AOL Voice Portal by AOL Voice Portal
users;

          (ii) Without limiting the generality of Section 2.1(a)(i), AOL shall
have the right to grant access to, and permit the use of the SpeechWorks
Software by, contractors and subcontractors retained from time to time by AOL or
any of its Affiliates solely as needed to furnish professional or technical
services to AOL or any of its Affiliates in connection with an AOL Voice Portal,
provided that such contractors and subcontractors execute an agreement with AOL
which contains provisions no less protective of the intellectual property rights
of SpeechWorks than those contained herein; and

          (iii) In partial consideration of the warrants to be issued pursuant
to the Common Stock and Warrant Purchase Agreement referenced in Section 7,
subject to clauses (I)-(III) of this Section 2.1(a)(iii) and the other terms of
this Section, SpeechWorks hereby authorizes AOL to grant licenses to the
SpeechWorks Software to third parties identified in writing by AOL whose content
is accessible by speech activated services via an AOL Voice Portal
(notwithstanding that [     ], including but not limited to [     ] or via other
[     ], provided, however, that the SpeechWorks Software shall not be used for
such other access), at [     ] cost to AOL or such third parties for such
SpeechWorks Software.  Such licenses shall be limited non-exclusive, non-
transferable, non-sublicensable, worldwide licenses, for a period of twenty four
(24) months from the date of grant of each such license, to use the SpeechWorks
Software solely in connection with use via an AOL Voice Portal by AOL Voice
Portal users.  Any grant of a license by AOL to a third party pursuant to this
Section 2.1(a)(iii) shall also be conditioned upon the following:

               (I) AOL shall require such third party to execute a license
agreement in a form consistent with the provisions of this Section 2.1(a)(iii)
to be agreed upon by AOL and SpeechWorks within thirty (30) days after the
Effective Date with respect to which SpeechWorks shall be an express third-party
beneficiary and licensor to such third party;

               (II) AOL shall provide to SpeechWorks a copy of such executed
license that shall include, without limitation, the number of ports licensed,
the location at which such third party plans to install the SpeechWorks Software
and a reasonably detailed description of the use of the SpeechWorks Software;
and

               (III) within five (5) business days of the receipt by SpeechWorks
of a copy of such executed license agreement, SpeechWorks shall provide to such
third-party a specifically identifiable copy of the Licensed Software.

          In addition to any license granted to a third party pursuant to this
Section 2.1(a)(iii) SpeechWorks authorizes AOL, in AOL's discretion, to offer to
such third party the opportunity to execute with SpeechWorks a [     ] fee-based
license to the SpeechWorks Software (the "Third Party License") at a discount
equal to [     ] percent ([     ]%) off of the [     ] list price then charged
generally by SpeechWorks to third party licensees.  In the event that such
third-party agrees to execute a Third Party

                                      -4-
<PAGE>

License, SpeechWorks shall pay to AOL an amount equal to [ ] percent ([ ]%) of
the [ ] list price then charged generally by SpeechWorks upon receipt by
SpeechWorks of the third party license fee.

          (iv) A voice portal associated with the [     ] service and operated
by AOL, although outside the scope of the grant of license to the SpeechWorks
Software in Section 2.1(a)(i) above, shall be included therein for purposes of
this Agreement.  In addition, in the event that AOL or an AOL Affiliate operates
a voice portal which does not otherwise fall under the grant of license to the
SpeechWorks Software under this Agreement, but which AOL demonstrates (x) is
operated by AOL or an AOL Affiliate as part of a larger strategic relationship
with the party for which such portal is operated and (y) is not otherwise
operated as part of an ASP or similar business strategy being implemented by
AOL, then AOL may request to SpeechWorks that such voice portal come under the
scope of the grant of license hereunder and SpeechWorks will reasonably consider
such request.  In the event that SpeechWorks determines that such voice portal
shall not fall under the scope of the grant of license hereunder, then AOL shall
be permitted to license the SpeechWorks Software from SpeechWorks for such
portal on [     ] per port pricing terms.

     (b) During the [     ] Period, [     ] Recognition Ports and System Seats
which may be used by  the permitted users specified in Section 2.1(a) [     ]
but (other than those already reported under the license in Section
2.1(a)(iii)(I)) shall be reported to SpeechWorks promptly on an Installation
Report; provided, however, that after the end of the [     ] Period, [     ]
Recognition Ports and System Seats that may be used by the permitted users
specified in Section 2.1(a) [     ] of Recognition Ports and System Seats
deployed immediately prior to the end of the Deployment Period, plus the
additional Recognition Ports and System Seats licensed under Section 2.7, if
any.

     (c)  AOL and the other permitted users specified in Section 2.1(a), [
], shall also be permitted to use (i) any currently available Rich Voice Content
listed on Exhibit A; (ii) any standard updates made available during the Term to
such Rich Voice Content listed on Exhibit A; and (iii) any other Rich Voice
Content not listed on Exhibit A but generally made available by SpeechWorks to
third-parties for no incremental cost, in each case only in connection with the
AOL Voice Portal and only to the extent such permitted users are entitled to use
the Licensed Software.  The use of all other Rich Voice Content not listed on
Exhibit A shall be subject to written terms and conditions to be mutually agreed
to by the parties; provided, however, that with respect to such Rich Voice
Content, AOL shall receive the [     ] then [     ] SpeechWorks customer for
such content.

     (d)  AOL, the AOL Affiliates and the other permitted users specified in
Section 2.1(a) obtain no rights in the Licensed Software pursuant to this
Agreement except the rights expressly granted hereunder.  Without limiting the
foregoing, the scope of the rights and licenses granted hereunder excludes (i)
all [     ], [     ] and [     ] service applications not used exclusively in
connection with the AOL Voice Portal, (ii) all [     ] and [     ] not [     ]
to an AOL Voice Portal, and (iii) all [     ] applications (including but not
limited to [     ], [     ], [     ] (i.e., [     ]), [     ], [     ] product,
and the like) not including any AOL [     ] portal or any other business
oriented content for which the target audience is either a [     ] or [     ]
users.  If AOL elects to extend the scope of the rights and licenses granted in
Section 2.1 to include any applications described in this Section 2.1(d), AOL
shall [     ] the then-current Version of the SpeechWorks Software to [     ] to
AOL.

2.2 Documentation License. Subject to the terms, conditions and restrictions set
forth in this Agreement, SpeechWorks hereby grants to each permitted user
specified in Section 2.1(a) a non-exclusive license, to use the Documentation,
and the Custom Software Documentation and to copy the Documentation and the
Custom Software Documentation only as necessary to enjoy the rights and licenses
granted to such permitted user under Section 2.1.

                                      -5-

provided that all such copies shall bear the original and unmodified copyright,
patent and other intellectual property markings as originally delivered by

environment not specified in Exhibit A. The parties respective intellectual
property rights with respect to the Custom Software and Custom Software

second year is $[     ], then the percentage retained by SpeechWorks in the
third year shall be [     ]%.  If such gross revenue in each of the third,
fourth, fifth and sixth years is $[     ], then the percentage retained by
SpeechWorks in the fourth, fifth, sixth and seventh years, respectively shall be

non-AOL content to its customers or other third parties that request it.  AOL
may terminate SpeechWorks' right and obligation to resell AOL Branded Content if
the SpeechWorks Software materially underperforms competitors in terms of
features, accuracy, response time and efficiency. AOL shall discuss with
SpeechWorks in good faith opportunities for the offering by SpeechWorks of
particular AOL Branded Content.

5.2 Open Architecture. An objective of both parties is to create and maintain an
open speech internet architecture (i.e., without limitation, a speech internet

and third party voice and speech internet applications). To the extent
reasonably practical and consistent with industry developments, SpeechWorks will
endeavor to keep the SpeechWorks Software platform open to third parties and
compatible with third party voice recognition systems and portals. AOL and
SpeechWorks also agree to work together to define and promote standards for the
open speech Internet.

5.3 Additional Languages.  SpeechWorks will offer to AOL additional language
versions (i.e., other than American English) of the SpeechWorks Software, when

languages.  Subject to resource availability and upon reasonable notice, such
additional languages will be provided to AOL at [     ] of (a) a [     ]
additional payment of $[     ] per language or (b) if such language has been
previously licensed, [     ] the then-current version of such language.
Delivery of such additional software will not be considered essential elements
to the functionality of the AOL Voice Portal licenses or related professional
services.  If SpeechWorks elects to make available additional language versions
of SpeechWorks Software, AOL shall [     ] customer [     ] in terms of [     ]
and [     ] with regard to this Section 5.3.

otherwise, (ii) shall accurately, correctly, and consistently manage and
manipulate data involving dates, including formulas that involve dates in one
century or dates in more than one century, and (iii) shall not cause an
abnormally-ending routine or process within an application or generate incorrect
values or invalid results involving date data.

     (d) SpeechWorks represents and warrants that the SpeechWorks Software does
not contain any disabling codes, termination logic or any other means to
terminate the use thereof by AOL and its Affiliates or to otherwise disrupt or
electronically repossess the SpeechWorks Software.

     (e) SpeechWorks represents and warrants that: (i) it has the full corporate

OF SECTIONS 7.1 AND 7.2 OF EXHIBIT C, STATE SPEECHWORKS' SOLE AND EXCLUSIVE

REVENUES AND LOSS OF PROFITS, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

SECTION 10 -- INFRINGEMENT MATTERS; INDEMNITIES

10.1  Indemnities.  SpeechWorks agrees, at its own expense, to defend or, at
its option, to settle, any claim or action brought against AOL to the extent it
is based on a claim that AOL's use of the Licensed Software in accordance with
the scope of this Agreement infringes or violates any United States patent,
United States copyright, trademark, trade secret or other intellectual property
right of a third party, and will indemnify and hold AOL harmless from and
against any damages, costs and fees of any kind whatsoever incurred (including
reasonable attorneys' fees) that are attributable to such claim or action.  AOL
agrees that SpeechWorks shall have the foregoing obligation only if AOL provides
SpeechWorks with: (i) prompt written notification of the claim or action; (ii)
sole control and authority over the defense or settlement thereof (and will
consult with AOL with respect thereto to the extent reasonably practicable); and
(iii) all available information, assistance and authority to settle and/or
defend any such claim or action (all at SpeechWorks' sole cost and expense).
AOL shall have the right, at its expense, to participate in any such claim
through counsel of its choice.

10.2  Limited Remedies. If any Licensed Software becomes, or in the opinion
of SpeechWorks is likely to become, the subject of an infringement claim or
action, SpeechWorks may procure, at no cost to AOL, the right to continue using
the Licensed Software. If AOL is enjoined, by order of a court or other
governmental body, from using the Licensed Software as contemplated by this
Agreement as a result of an infringement claim or action, then SpeechWorks may,
at its sole option: (i) procure, at no cost to AOL, the right to continue using
the Licensed Software; (ii) replace or modify the SpeechWorks Software to render
it noninfringing, provided there is no material loss of functionality; or (iii)
if, in SpeechWorks' reasonable opinion, neither (i) nor (ii) are commercially
feasible terminate the license and refund the amounts AOL paid for such
SpeechWorks software. Except as provided in Section 10.1, the foregoing
provisions of this Section 10.2 state SpeechWorks' sole obligation and AOL's
exclusive remedy in the event any such claim.

                                      -15-
<PAGE>

10.3 Limitation of Liability; Additional Indemnities. SpeechWorks will have no
liability under this Section 10 or the limited warranty provided for in Section
9.1, or Section 7.1 of Exhibit C, for any claim or action where: (i) such claim
or action would have been avoided but for modifications of the Licensed
Software, or portions thereof, made by any party other than SpeechWorks (or any
third party retained by SpeechWorks pursuant to Section 3.3 of Exhibit C) after
delivery to AOL; (ii) such claim or action would have been avoided but for the
combination or use of the Licensed Software, or portions thereof, with other
products, processes or materials (including but not limited to the AOL
Technology) not otherwise recommended by SpeechWorks; (iii) after AOL is
enjoined from using the Licensed Software, AOL continues allegedly infringing
activities after being notified thereof (provided that AOL shall also indemnify
SpeechWorks against liabilities incurred by SpeechWorks as a result of AOL
continuing to engage in allegedly infringing activities after being notified
thereof, but prior to being enjoined from using the Licensed Software); (iv) AOL
continues allegedly infringing activities after being informed of modifications
that would have avoided the alleged infringement, provided that there is not
material loss of functionality; (v) AOL's use of the Licensed Software is not
strictly in accordance with the terms of this Agreement; or (vi) except to the
extent that AOL purchases maintenance and support services for such Custom
Software, such claim or action arises directly out of any portion of the Custom
Software created solely for the purpose of allowing the Licensed Software to
function in conjunction with an AOL Voice Portal or otherwise created pursuant
to detailed technical specifications provided to SpeechWorks by AOL. AOL agrees
to indemnify and hold SpeechWorks harmless from and against all losses, damages
and expenses, including reasonable attorney's fees, in connection with any
claims brought against SpeechWorks and its officers, employees, agents or
subcontractors arising as a result of any of the conditions described in clauses
(i) through (iv) above. SpeechWorks agrees that AOL shall be released from the
foregoing obligation unless SpeechWorks provides AOL with: (i) prompt written
notification of the claim or action; (ii) sole control and authority over the
defense or settlement thereof; and (iii) all available information, assistance
and authority to settle and/or defend any such claim or action.

SECTION 11 -- DEPLOYMENT PERIOD; TERM; TERMINATION

11.1  Initial Deployment Period; Optional Extension; Automatic Extension. The
initial period during which AOL may deploy an unlimited number of Recognition
Ports (as described in Section 2.1(b)) shall commence on the Effective Date and
continue for three (3) years thereafter; provided, however, that AOL may extend
such initial 3-year unlimited deployment period for up to an additional three 1-
year periods by written notice to SpeechWorks, and payment of the extension fees
specified in Section 6.2 above, at any time prior to the end of the then current
unlimited deployment period.  The initial 3-year unlimited deployment period and
each [     ]-year extension thereof are collectively referred to in this
Agreement as the "[     ] Period." When AOL has paid fees under Section 6.1 and
Section 6.2 of $[     ] in the aggregate, the Deployment Period shall
automatically be extended for an indefinite period of time until terminated
pursuant to Section 11.3, 11.4, 11.5 or 13.2; provided, however, that if the
amount of fees paid by AOL under Section 6.1 and Section 6.2 immediately prior
to the end of the Deployment Period (the "Actual Fees Paid") is less than $[
], AOL shall in its discretion be permitted to pay to SpeechWorks the difference
between $[     ] and the Actual Fees Paid and thereby be deemed to have paid $[
] for purposes of this Section 11.1.  Notwithstanding the foregoing, the
Deployment Period shall terminate automatically upon any termination or
expiration of this Agreement unless AOL has paid fees under Section 6.1 and
Section 6.2 of $[     ] in the aggregate prior to the end of the Term; provided,
however, that except in the case of a termination by SpeechWorks under Section
11.3 or by AOL under Section 11.5, AOL shall thereafter be permitted for a
period of twenty-four (24) months (i) to deploy Recognition Ports [     ] the
SpeechWorks [     ]  [     ]; and (ii) to [      ]  maintenance and support
services pursuant to [     ] maintenance and support service fee schedule at
which SpeechWorks [     ].

11.2  Term. The term of this Agreement (the "Term") shall commence on the
Effective Date and shall continue thereafter until terminated in accordance with
Section 11.3, 11.4, 11.5 or 13.2.

11.3  Termination By Either Party. Either party may terminate this Agreement
immediately upon giving notice in writing to the other party if such other party
commits a material breach of this Agreement and shall have failed to cure such
breach within thirty (30) days of receipt of a request in writing from the
notifying party to do so; provided, however, that a breach by SpeechWorks of its
obligations under Section 9 shall not be deemed to be a material breach but
instead shall be subject to the exclusive remedies set forth in Section 10.2.
The parties acknowledge that the failure to pay to SpeechWorks any material
amount when due hereunder shall constitute a material breach.  Notwithstanding
the foregoing, SpeechWorks shall have the right to terminate this Agreement
immediately upon the breach by AOL of any material term of Section 2.  Upon
termination by AOL under this Section 11.3, notwithstanding anything in this
Agreement to the contrary, (a) without AOL being obligated to pay any license
fees after the date of such Termination (other than unpaid license fees that had
become due prior to the date of the Termination), the number of Recognition
Ports and System Seats which may be used by the permitted users specified in
Section 2.1(a)(i) and (ii), and the time period during which AOL may deploy such
Recognition Ports and System Seats, shall not be limited but shall be reported
to SpeechWorks promptly on an Installation Report, and (b) SpeechWorks shall
continue to provide Maintenance and Support Services, upon payment therefor, in
accordance with this Agreement, including but not limited to Annex 1 of Exhibit
D hereto, until the later of (i) the date two years after the effective date of
termination or (ii) the sixth anniversary of the Effective Date.

11.4  Termination for Bankruptcy/Insolvency or Changes in Business.  Either
Party may terminate this Agreement immediately following written notice to the
other Party if the other Party (i) ceases to do business in the normal course,
(ii) becomes or is declared insolvent or bankrupt, (iii) is the subject of any
proceeding related to its liquidation or insolvency (whether voluntary or
involuntary) which is not dismissed within ninety (90) calendar days or
(iv) makes an assignment for the benefit of creditors.

11.5  TERMINATION BY AOL

     (a) AOL may terminate this Agreement upon written notice given to
SpeechWorks if SpeechWorks does not, on or before the tenth (10th) business day
following the Effective Date, (i) satisfy the conditions set forth in Sections
6(b)(iii), 6(b)(v) and 6(b)(vi) of the Common Stock and Warrant Purchase
Agreement referenced in Section 7; and (ii) issue the warrant to AOL as required
by Section 1(b) such Common Stock and Warrant Purchase Agreement.

     (b)  AOL may also terminate this Agreement at [     ] ([     ]) [     ]
[         ]. The foregoing termination shall be effective immediately prior to
the first anniversary of the Effective Date that follows SpeechWorks' receipt of
such termination notice, unless SpeechWorks receives the termination notice less
than thirty (30) days prior to the next anniversary of the Effective Date in
which case the termination shall be effective immediately prior to the second
anniversary of the Effective Date that follows SpeechWorks' receipt of such
termination notice. Notwithstanding the foregoing, AOL shall still be obligated
to pay the license fee specified in Section 6.1(b) if AOL terminates this
Agreement pursuant to this Section 11.5 prior to the first anniversary of the
Effective Date.

11.6 Effect of Termination. Immediately upon the termination of this
Agreement (whether pursuant to this Section 11 or for any other reason):
(a) except for the rights, licenses and obligations that by the express terms of
this Agreement are to survive the termination of this Agreement, all rights,
licenses and obligations of the parties under this Agreement shall immediately
terminate; and (b) any outstanding amounts due to either party hereunder shall
immediately become due and payable. Without limiting the generality of the
foregoing, the rights of AOL and any AOL Affiliate or third party specified in
Section 2 to use the Licensed Software as set forth herein shall survive the
termination of this Agreement unless this Agreement has been terminated by
SpeechWorks as a result of (x) AOL's breach of the scope of the license set
forth in Section 2, (y) AOL's failure to pay any license fees hereunder when due
or within the applicable cure period, or (z) any material breach by AOL of
Section 8, or of Section 6 of Exhibit C or Section 6 of Exhibit D; in which case
all rights and licenses granted hereunder with respect to the Licensed Software,
Documentation and Custom Software Documentation shall immediately terminate and,
upon request by SpeechWorks, any person or entity that had been using Licensed
Software pursuant to a license granted hereunder shall certify in writing to
SpeechWorks its non-use, deletion and/or destruction of the Licensed Software,
Documentation and Custom Documentation.

11.7 Survival. Notwithstanding anything to the contrary in this Section 11, the
provisions of Sections 6.3, 6.4, 6.5 through 6.9, 8, 9, 11, 14, 15.4, 15.6,
15.9, 15.10 and 15.11 shall survive termination of this Agreement.

SECTION 12--SOURCE CODE ESCROW

     Within thirty (30) days after the Effective Date, SpeechWorks and AOL shall
execute a source code escrow and license agreement substantially in the form of
Exhibit F with appropriate modifications to conform to the terms of this
Agreement (the "Escrow Agreement"). Each time SpeechWorks delivers a copy of
SpeechWorks Software or an Update or Version hereunder, SpeechWorks shall, at
its expense, place a copy of the Source Code of the SpeechWorks Software, Update
or Version into escrow. Without limiting the provisions of the Escrow Agreement,
and in addition to the Release Conditions (as defined in such Escrow Agreement),
in the event of a Trigger Event (hereinafter defined) where SpeechWorks is the
acquired party and the Acquiring Entity (hereinafter defined) is a Specified AOL
Competitor, the Source Code will be released to AOL and AOL shall be entitled to
exercise the license to such Source Code specified in the Escrow Agreement.
AOL's right to receive Source Code is at all times subject to Section 13.3
below.

SECTION 13--ASSIGNMENT AND CHANGE OF CONTROL

13.1 Assignment. Except as expressly permitted herein, neither party may assign,
transfer or pledge this Agreement, or any interest, license, or rights of any
kind herein, in any manner, without the prior written consent of the other party
to this Agreement, except (a) in the case of SpeechWorks, in connection with a
merger, reorganization or sale of substantially all of the business of
SpeechWorks, or, (b) in the case of AOL, (i) in connection with a merger,
reorganization or sale of substantially all of the business relating to the AOL
Voice Portal, or (ii) any assignment predicated upon the merger of AOL and Time
Warner, Inc. Any purported assignment, transfer or pledge of this Agreement in
violation of this Section 13 shall be null and void. Any permitted assignment,
transfer or pledge of this Agreement shall be subject to Section 13.2.

13.2 Mergers, Acquisition of Assets or Change of Control.

     (a)  (i)  If SpeechWorks consummates any permitted transaction or series of
transactions under which an entity (the "Acquiring Entity") would acquire,
whether by merger or otherwise, (A) substantially all of the business of
SpeechWorks or (B) beneficial ownership or control, directly or indirectly, of
more than fifty percent (50%) of the outstanding shares or securities
representing the right to vote for the election of directors of SpeechWorks
(each a "Trigger Event"), this Section 13.2 shall apply.

          (ii) Upon a Trigger Event in which the Acquiring Entity is a Specified
AOL Competitor or upon a Trigger Event after which SpeechWorks announces that it
is shutting down or migrating from

                                      -17-
<PAGE>

the current Speechworks platform to a different speech recognition platform
(e.g. the Nuance platform, a different proprietary platform, or to any other
speech recognition platform) or de facto shuts down or migrates away such
platform (e.g. by no longer providing a similar level and quality of licensing
and/or support services to third party licensees of such platform or similar
indicia), then: (A) AOL shall be entitled, at its option, to terminate this
Agreement upon thirty (30) days' written notice, (B) without AOL being obligated
to pay any license fees after the date of the Trigger Event (other than unpaid
license fees that had become due prior to the date of the Trigger Event), the
number of Recognition Ports and System Seats which may be used by the permitted
users specified in Section 2.1(a)(i) and (ii), and the time period during which
AOL may deploy such Recognition Ports and System Seats, shall not be limited but
shall be reported to SpeechWorks promptly on an Installation Report, (C) the
Acquiring Entity shall agree in writing to provide Maintenance and Support
Services, upon payment therefor, in accordance with this Agreement, including
but not limited to Annex 1 of Exhibit D, until the later of (1) the date two
years after the date of the Trigger Event or (2) the sixth anniversary of the
Effective Date, (D) on or prior to the date which is within 60 days of such
termination SpeechWorks will refund to AOL all licensing fees paid by AOL to
SpeechWorks under this Agreement up to the date of such termination, and (E) at
AOL's option SpeechWorks shall provide AOL with the services, for one full year
after such termination, of the equivalent of five full time SpeechWorks
engineers or similar SpeechWorks consultants qualified to work with AOL to
effect a transition of the AOL Voice Portals away from the SpeechWorks platform
and on to an alternate platform chosen by AOL. In the event of any Trigger
Event, prior to consummating such transaction or series of transactions, if this
Agreement is not terminated in accordance with (A) above, the Acquiring Entity
shall agree in writing to be bound by the terms and conditions of this
Agreement.

          (iii) Upon aTrigger Event in which the Acquiring Entity is a Specified
SpeechWorks Competitor or upon a Trigger Event after which Speechworks announces
that it is shutting down or migrating from the current Speechworks platform to a
different speech recognition platform (e.g. the Nuance Platform, a different
proprietary platform, or to any other speech recognition platform) or de facto
shuts down or migrates away such platform (e.g. by no longer providing a similar
level and quality of licensing and/or support services to third party licensees
of such platform or similar indicia) (A) notwithstanding anything in Section 3.1
of Exhibit D to the contrary, SpeechWorks shall provide support for the then
current production Version of the Licensed Software in accordance with Exhibit D
and shall support the immediately prior release for a period of three (3) years
after the release of the then current production Version, (B) upon a migration
by the Acquiring Entity off of the SpeechWorks platform, without AOL being
obligated to pay any license fees after such migration (other than unpaid
license fees that had become due prior to such migration), the number of
Recognition Ports and System Seats which may be used by the permitted users
specified in Section 2.1(a)(i) and (ii), and the time period during which AOL
may deploy such Recognition Ports and System Seats, shall not be limited but
shall be reported to SpeechWorks promptly on an Installation Report, and (C) the
Acquiring Entity shall agree in writing to provide Maintenance and Support
Services, upon payment therefor, in accordance with this Agreement, including
but not limited to Annex 1 of Exhibit D, until the later of (1) the date two
years after the date of the Trigger Event or (2) the sixth anniversary of the
Effective Date.

     (b) If prior to a firm commitment underwritten public offering by
SpeechWorks pursuant to an effective registration statement filed under the
Securities Act of 1933, as amended, in which shares of the common stock of
SpeechWorks are approved for listing on a national securities market, either (i)
SpeechWorks receives a bona fide offer from a third party to affect a Trigger
Event; or (ii) SpeechWorks determines to seek an offer from any third party to
affect a Trigger Event, then in either such event SpeechWorks shall before
executing any binding documentation with respect thereto other than a
nondisclosure agreement, but including but not limited to a "standstill"
provision, provide to AOL written notice of the receipt of such offer or its
determination to seek such offers, together with description of the material
terms (including but not limited to price, form of consideration and type of
security) of any such offer (but excluding the identity of the third
party(ies)). For a period of ten (10) business days from such notice,
SpeechWorks will not sign a definitive agreement to engage in a Trigger Event.

13.3 Acquisition of Specified SpeechWorks Competitor. If at any time AOL, or
any AOL Affiliate, directly or indirectly controls, is controlled by or is under
common control with (as control is defined in the definition of Affiliate) a
Specified SpeechWorks Competitor, then AOL's right to receive Source Code under
Section 12, and Section 4.1(d) of the Escrow Agreement, shall be suspended until
such time when AOL has divested itself or otherwise disposed or ceased
operations of those business units responsible for software that is similar in
nature or functionality to the Licensed Software (and has not reacquired or
resumed such operations, in which case such rights shall again be suspended and
AOL, if it has received Source Code under the sections referenced above, shall
immediately delete, destroy or return all copies of the Source Code and related
documentation, and certify the same to SpeechWorks).

SECTION 14 -- DISPUTE RESOLUTION

14.1 Amicable Resolution. The parties shall first attempt to amicably resolve
any dispute that may arise under this Agreement. If the parties cannot resolve
the dispute within thirty (30) days, either party may refer the dispute to
arbitration pursuant to Section 14.2.

14.2 Arbitration pursuant to Section 14.1, any controversy or claim arising out
of or relating to this Agreement shall be settled by arbitration in accordance
with the Commercial Arbitration Rules of the American Arbitration Association,
except that the parties shall be entitled to reasonable document and deposition
discovery from each other limited to the matters in dispute. A judgment upon the
award rendered by the arbitrator shall be final and nonappealable, and may be
entered in any court having jurisdiction thereof. The arbitration proceeding
shall be conducted by a single arbitrator knowledgeable regarding matters in the
software industry and held in Boston, Massachusetts or such other location as
the parties may mutually agree upon. Notwithstanding the foregoing, (a) AOL
recognizes and acknowledges that any use or disclosure of the Licensed Software,
Documentation, Custom Software Documentation or SpeechWorks' Confidential
Information, by AOL and (b) SpeechWorks recognizes and acknowledges that any use
or disclosure of the AOL Technology and any Confidential Information, of AOL or
its Affiliates, in either event in a manner inconsistent with the provisions of
this Agreement may cause SpeechWorks or AOL (as the case may be) irreparable
damage for which remedies other than injunctive relief may be inadequate, and
SpeechWorks or AOL (as the case may be) may therefore seek from any court of
competent jurisdiction, injunctive and other equitable relief as appropriate. If
either party seeks injunctive or other equitable relief in the event of a breach
or threatened breach of this Agreement by the other party or such other party's
Affiliates, then such other party agrees that it shall not allege in any such
proceeding that the party seeking such injunctive or equitable relief has an
adequate remedy at law. If a party seeks any equitable remedies (including
injunctive relief), it shall not be precluded or prevented from seeking remedies
at law, nor shall it be deemed to have made an election of remedies.

SECTION 15 -- GENERAL TERMS

15.1 Force Majeure. Except for the obligation to make payments, nonperformance
of either party shall be excused to the extent that performance is rendered
impossible by strike, fire, flood, governmental acts or orders or restrictions,
failure of suppliers, or any other reason where failure to perform is beyond the
reasonable control of the non-performing party.

15.2 Notices. Any required notices hereunder shall be given in writing at the
address of each party set forth above, to the persons identified for such
purpose in the Common Stock and Warrant Purchase Agreement referenced in Section
7 above, or to such other in the manner contemplated herein, and shall be deemed
served when delivered or, if delivery is not accomplished by reason or some
fault of the addressee, when tendered.

                                      -19-
<PAGE>

15.3 Relationship Between the Parties. In all matters relating to this
Agreement, AOL and SpeechWorks shall act as independent contractors. Except as
may be otherwise expressly permitted hereunder, neither party will represent
that it has any authority to assume or create any obligation, expressed or
implied, on behalf of the other party, or to represent the other party as agent,
employee, or in any other capacity.  Neither party shall have any obligation,
expressed or implied, except as expressly set forth herein.

15.4 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York without giving effect to
principles of conflicts of laws.

15.5 Export Controls; Government Use.  AOL agrees and certifies that neither
the Licensed Software, nor any other technical data received from SpeechWorks,
nor the direct product thereof, will be exported or re-exported outside the
United States except as authorized and as permitted by the laws and regulations
of the United States.  Any use of the Licensed Software by the U.S. Government
is conditioned upon the Government agreeing that the Licensed Software is
subject to Restricted Rights as provided under the provisions set forth in
subdivision (c)(1)(ii) of Clause 252.227-7013 of the Defense Federal Acquisition
Regulations Supplement, or the similar acquisition regulations of other
applicable U.S. Government organizations.

15.6 Entire Agreement; Headings; Counterparts. This Agreement constitutes the
entire agreement and understanding between the parties with respect to the
subject matter hereof, and supersedes all prior agreements, arrangements and
undertakings between the parties.  No addition to or modification of any
provision of this Agreement shall be binding upon the parties unless made by a
written instrument signed by a duly authorized representative of each of the
parties.  The headings to the sections of this Agreement are for ease of
reference only and shall not affect the interpretation or construction of this
Agreement. This Agreement may be executed in counterparts, each of which shall
be deemed to be an original and all of which shall be deemed to be an original
instrument. The Exhibits are an integral part of this Agreement.

15.7 Publicity. Consistent with the applicable regulatory requirements, the
parties shall issue a mutually agreed upon joint press release, at a mutually
agreed upon time, announcing the selection of SpeechWorks and the collaboration
to launch the AOL Voice Portal and to collaborate on industry standards.  Not
withstanding the foregoing in the event that SpeechWorks, on the advice of
counsel, is required to issue a press release under applicable law or regulatory
requirement, SpeechWorks will provide reasonable notice to AOL and an
opportunity to comment on such press release.  Finally, in partial consideration
of the warrants to be issued pursuant to the Common Stock and Warrant Purchase
Agreement referenced in Section 7, the parties have agreed to additional
requirements in connection with publicity as more fully set out on Exhibit G.

15.8 Partial Invalidity; Waiver. If any provision of this Agreement or the
application thereof to any party or circumstances shall be declared void,
illegal or unenforceable, the remainder of this Agreement shall be valid and
enforceable to the extent permitted by applicable law. In such event the parties
shall use their best efforts to replace the invalid or unenforceable provision
by a provision that, to the extent permitted by applicable law, achieves the
purposes intended under the invalid or unenforceable provision.  Any deviation
by either party from the terms and conditions with applicable laws, rules and
regulations shall not be considered a breach of this Agreement.  No failure of
either party to exercise any power or right given either party hereunder or to
insist upon strict compliance by either party with its obligations hereunder,
and no custom or practice of the parties at variance with the terms hereof shall

                        SPEECHWORKS SOFTWARE; PRODUCTS


I.  SpeechWorks Software.
    --------------------

The software available for licensing under the terms of the Agreement to which
this Exhibit is attached is as follows:

SPEECHWORKS(R) is a solution for speech-enabling transactional applications over
the telephone. packaged as six functional components:

     1.  SpeechWorks SMARTRecognizer(TM) recognizes words or phrases from
     individual vocabularies in the call flow and provides processing of phrases
     and sentences. This engine supports a range of hardware platforms and
     scales to thousands of phone lines. Its features include:

     2.  SPEECHWORKS DIALOGMODULES(TM) are high-level building blocks
     representing frequently used caller interactions that developers can
     assemble and integrate into applications. Each DialolgModule encapsulates a
     particular task such as capturing a "yes" or "no" response or creating a
     voice menu. The DialogModules are made available in three bundles/packages.

       A.  BASE:  Includes recognition kernel, reporting tools, and the
       following DialogModules:

       AlphaNumeric String - Collects a string of connected (pauses are not
       required) numbers and letters. Patterns or a list of valid strings can be
       specified.

       Continuous Digits - Recognizes a string of connected digits only.
       Constraints such as string length or the allowed values can be specified.
       Item List - Lets callers speak words or phrases from a list (up to 250
       words), e.g. "Please say the name of the person you are calling?" or
       "What stock would you like to buy?"

       VoiceMenu - Lets callers choose a word or phrase from a list (maximum
       of 20). Menus are similar to ItemLists, but shorter so that the prompt
       can read each item to the caller.

       YesNo - Performs the essential function of identifying affirmative and
       negative responses from callers.

       B.  EXTENDED:  Includes Base DialogModules, recognition kernel, reporting
       tools, and the following DialogModules:

       CreditCardNumber - Collects a credit card number. Can understand the
       major credit cards and many private label cards from retailers

       CCExpDate - Collects the expiration date for a credit card, usually month
       and year. It recognizes the last day of a given month as well.

       Currency - Lets callers speak a monetary value in a natural way, e.g.,
       "One hundred twenty-five dollars and thirty two cents. Non US dollars can
       be customized.

       Date - Collects dates in several formats, e.g., June Fourth or 6/4/70,
       nicknames can be mapped, e.g., Christmas or today, allowing callers to
       speak a date in a natural way

       ItemList - Up to 2,500 words

       NaturalNumbers - Collects whole numerical amounts; callers can say "fifty
       four hundred".  Vocabulary for units can also be added, as in "a thousand
       boxes".

       SocialSecurityNumber - Collects a 9-digit US Social Security number.
       Illegal numbers, such as those beginning with three zeroes, are screened
       out

                                      A-1
<PAGE>

       Spelling - Recognizes individual letters so that callers may choose to
       spell out a request.

       TimeOfDay - Collects a naturally spoken time of day.  Callers can use 12-
       hour or 24-hour times, as well as prefix words such as "about" and
       "around TelephoneNumber - Collects a phone number in the "North American
       Numbering Plan" consisting of ten, seven or three digits.  It allows
       common phrases such as "area code" and "one eight hundred".

       ZipCode - Recognizes a five and/or nine digit United States ZIP code

       C.  PROFESSIONAL NL (NATURAL LANGUAGE): Includes Extended DialogModules,
       recognition kernel, reporting tools, and the following DialogModules:

       ItemList - Greater than 2,500 words or phrases

       CustomContext  - Provides the ability to run the results of custom
       modules created with the Software Development Kit.

       The Professional NL will typically require some level of SpeechWorks
       custom development services or development support.

       Name - Available with Release 6.0 making it easier to collect a person's
       first, last or first and last names where the names are completely
       unknown.  Speech Attendant apps should continue using the ItemList
       DialogModules

     3.  SPEECHWORKS REPORTING AND ANALYSIS TOOL is bundled with each of the
     DialogModule packages. The tool generates text diagnostic reports about
     applications based on call logging data. The reports included are:

       Call-Start - displays a percentage breakdown by one hour time period of
       when calls are initiated helping to identify peaks in system usage.

       Call-Length  - displays a percentage breakdown of calls by duration
       tracking the efficiency of user interface improvements that result in the
       reduction of call length.

       Module Transaction Results - summarizes execution results for each
       DialogModule presenting an overall success rate.  Success rates lower
       than 90% indicate problem areas.

       Module Callflow Results - summarizes results of each attempt to collect
       the primary DialogModule data from the caller.  High values for denied
       confirmation and rejection indicate that recognition is not performing
       well.

       Context Results  - summarizes the result of each recognition event.  This
       report illustrates a complete picture of the caller experience at the
       transaction level.

       Module Vocabulary Results - summarizes results classified by the answer
       returned by the recognizer via a DialogModule.  This report can be used
       to give an indication of a) how effective the system recognized a
       caller's utterance and b) how easily callers were able to clarify/confirm
       what was said.

       Context Stats - summarizes various additional statistics for each
       recognition context.  This report allows quick identification of problem
       contexts indicating that improvements are required

     4.  SPEECHWORKS SOFTWARE DEVELOPMENT KIT (SDK) includes the following suite
     of editors and utilities for configuring DialogModules, providing service
     management functions, and supporting ongoing tuning and maintenance:
     Vocabulary Editor (VED), Grammar Development Tools and Application Tuning
     Tools. Included with the SDK are Four (4) Professional NL Run Time Port
     licenses, for development purposes only.

     5.  SPEECHWORKS VOCABULARY LIBRARIES supply pre-packaged and continuously
     maintained language contexts for spoken words/phrases. The User Interface
     for the application using these libraries is not included. The following
     libraries are currently available: (i) Stock Names & Symbols Vocabulary and
     (ii) Mutual Fund Names & Symbols Vocabulary.

sufficient to deliver each Deliverable on or before the applicable Milestone
Dates as agreed under the Statement of Work.

3.2  AOL Delay.  AOL acknowledges that any delay by AOL in providing data,
access, or services required by SpeechWorks to complete a Milestone will give
SpeechWorks, upon written notice to AOL, the right to delay subsequent
Milestones by up to: (a) an equivalent delay if the AOL delay is [     ] or
less; (b) [     ] for each [     ] of [       ], if the [      ] is more than
[     ], but less than [      ]; or (c) an equivalent [    ] plus [       ] if
the [       ] is [     ] or longer. In the event of (b) or (c), the parties
will meet to discuss the schedule for resuming work, but such schedule shall not
require SpeechWorks to resume work any sooner than the day after the last day of
delay permitted in this Section 3.2.

3.3  Use of Third Party Contractors. SpeechWorks may, from time to time, engage
third parties to render services in connection with SpeechWorks' development of
the Deliverables; provided, however, that all such third parties who perform

[                        ].

4.  ACCEPTANCE OF DELIVERABLES

4.1  Initial Testing; Rejection. SpeechWorks shall inform AOL as it completes
each Deliverable.  Within [     ] ([     ]) days (the "Acceptance Period") after
receipt of a Deliverable that is associated with a Milestone Fee, AOL may, upon
written notice (the "Rejection Notice") to SpeechWorks, reject any such
Deliverable which fails materially to satisfy the Acceptance Criteria for such
Deliverable.  In any such Rejection Notice, AOL shall document in reasonable
detail the relevant part of the Acceptance Criteria to which the Deliverable
failed materially to satisfy.

4.2  Correction of Failures. SpeechWorks shall use all commercially reasonable
efforts to correct any failure(s) materially to satisfy Acceptance Criteria that
both: (a) are documented in a Rejection Notice that AOL provides in compliance
with Section 4.1 of this Exhibit C and (b) the existence of which SpeechWorks
can confirm; and to deliver the corrected Deliverable to AOL within fifteen (15)
days of receiving such Rejection Notice.  Upon re-delivery of the Deliverable,
AOL shall have an additional Acceptance Period to re-perform tests and establish
that the corrected Deliverable conforms with applicable Acceptance Criteria and
may give a Rejection Notice to SpeechWorks within such additional Acceptance
Period of any continuing failure(s) materially to satisfy Acceptance Criteria.
The foregoing acceptance/rejection/correction process shall be repeated until
all such failures have been corrected by SpeechWorks and AOL's acceptance of the
Deliverable; provided, however, that if, after three (3) attempts SpeechWorks is
unable to correct material failure(s) to satisfy Acceptance Criteria, AOL may
reject the Deliverable.  In the event of such rejection, AOL shall return such
rejected Deliverable, including any copies thereof, and the related
documentation, including any copies thereof, to SpeechWorks.  In such event,
unless the parties otherwise agree in writing, [                     ] to [   ]
all [       ] and other [                  ] by [
      ] [       ], and SpeechWorks shall be under no obligation to continue
to produce Deliverables for the Project for which the rejected Deliverables were
produced.

4.3  Deemed Acceptance. Notwithstanding anything to the contrary in this
Section 4, a Deliverable will be deemed accepted and the associated Milestone
Fee shall be due immediately if either (a) AOL deploys such Deliverable in a
production environment, taking "live" calls; or (b) SpeechWorks receives no
Rejection Notice within a relevant Acceptance Period.

5.  CONSIDERATION; MAINTENANCE AND SUPPORT

5.1  Price.  Except as otherwise provided in Section 2.2 of this Exhibit C, in

                             ANNEX 1 TO EXHIBIT C
                        PRECURSOR TO STATEMENT OF WORK

I.  Objective of Document.
    ---------------------

The following is a general description of the scope and functionality of the AOL
Voice Portal, as well as the resources and remuneration that the parties will
respectively provide in developing [     ] of the AOL Voice Portal.  This
document shall be used as the basis for the definitive Statement of Work to be
developed and agreed to with respect to [     ], which definitive Statement of
Work shall be incorporated by reference into and constitute a part of this
Annex 1.

     The parties recognize that the specifics or scope of the AOL Voice Portal
may shift as the definitive Statement of Work is developed or during the
development or deployment of the AOL Voice Portal itself.  In such cases, the
parties will work together to develop a plan (resource commitments,
remuneration, etc.) that is similar to the plan outlined herein, including
specifically SpeechWorks deploying an adequate amount of resources to accomplish
such plan; provided, however, that SpeechWorks shall provide to AOL at a minimum
the resource commitment specifically enumerated in Section IX hereof at AOL's
option as outlined in Section IX.

II.  Voice Portal Principles.
     -----------------------

     This document describes currently anticipated features and functionality
for an [     ] voice portal service, which will initially be optimized for AOL
subscribers. The initial delivery ([     ]) will consist of an [     ]
navigation system and a set of [     ] voice-sites representing key AOL and
[    ] properties.

     The service is intended to be open and extensible to [ ] since, to the
degree possible and as provided in [    ] subsequent to [     ] (or, if
requested by AOL, within [      ] for incremental consideration according to
the principles outlined in Section VIII and Section IX below), it will employ a
standards-based navigation system and will use VoiceXML. Specifically, the goal
is to allow:

          - The AOL Voice Portal service to (1) expand easily beyond the initial
set of content offerings, and (2) access content outside the initial AOL Voice
Portal service offering ([      ]sites etc.). This will enable AOL to leverage
new business opportunities as they become available.

          - The AOL Voice Portal content to be accessed by other compatible
voice browsers that might emerge as the Speech-enabled Web expands

     Throughout this project, AOL intends to develop the expertise required to
become a leading player in the emerging field of voice content. Working with
SpeechWorks, AOL's objective is to gain the tools and skills necessary to:

          - Design, develop and produce voice sites (for its [    ] or [    ]).
          - Deploy and maintain a scalable service
          - Develop and product audio prompts / content

                                      C-7
<PAGE>

III.  Voice Portal Functionality.
      --------------------------

     As currently contemplated, at [     ] launch, Voice Portal users will
dial an [     ] number and be connected to a  speech application which will
allow them navigation to a selection of voice enabled content: [     ],
[     ], [     ] and [     ], and sites ([     ]): [     ], [     ] [     ],
[     ].  In addition, the AOL Voice Portal will interact with the AOL [     ]
to provide AOL Voice Portal Users with access to the AOL [     ] access to
their [     ], either through a voice interface, or via a a oetrombonea [____]
call out to/back from that service.  In addition, the service will enable
[     ], including adds that offer the ability to "[     ]" [     ].

NOTE: several of the above applications have already been developed
(e.g., [     ] and "[     ]") and the [     ] and [     ] may be useful as
foundations (given that the content has already been structured for a limited
form factor).

IV.  Registration.
     ------------

     AOL promotions will initially notify [     ]about the AOL Voice Portal
service and [     ].   All [     ] of the [     ] (e.g.,  not [     ]) can
become authenticated members..   Those who opt to sign up for the AOL Voice
Portal service will be asked to enter an [     ] and [     ]. This [     ]
will be a the [     ] of the [     ] from which they expect to call the
service.   The [     ] will be [     ] selected by the member.  Creation of a
secure-ID login to the AOL namespace will be co-built by AOL and SpeechWorks.

V.  Sign In.
    -------

     Once registered  with the AOL Voice Portal, ,members can call the [     ]to
access the service.   If they are calling from the [     ] the ANI will be
verified and they will be simply asked to type in or say the PIN.   If they are
calling from a phone other than the designated primary phone number they will be
asked to key in the [     ] and then the [     ].


VI.  Channels and Other Features.
     ---------------------------

     The AOL Voice Portal will be organized into [     ].   Above the [     ]
will be a welcome layer that will include sign-in, introduction, help,
promotions, and possibly [     ].  Each [     ] will integrate functionality
from other [     ] so that members can move in a fluid fashion between
functions (e.g., [     ] and [     ].) The [     ] selection will be as follows:

[     ]/[     ]/[     ]/[     ]:
- [     ]
- [     ]
- [     ]
- [     ]
- [     ]
- [     ]
- [     ]
- [     ]
- [     ]
- [     ]

[     ]:

     Integration of the existing [     ] service (currently in beta), with a
voice driven interface (note: key issues here are authenticating the member
[     ] and developing a voice recognition based TUI).

[     ]:

     The ability to [     ] and track results for [     ], including an option
for the user to respond and be transferred to either (a) a routine that offers
more pre-recorded information, or (b) directly to the [     ] [     ].

[     ]:

     This [     ] reproduces current [     ] functionality including:

          - [     ]
          - [     ]
          - [     ] ([     ])

[     ]:

     Integration of the [     ] application featuring:

          - [     ].

VIII.  Estimated Timing and Resource Commitments.

Timing:

     .  Provided deal is executed no later July 15, Speechworks to lead a
        product kickoff meeting within [     ] [     ] of execution.

     .  Speechworks to deliver working system deployed on AOL's required number
        of ports no later than [     ] [     ] from kickoff if the system is
        [     ] in [     ].  If the system is [     ] using [     ],
        SpeechWorks will deliver the application within [     ] from kickoff.

Resource Commitments:

     .  Speechworks anticipates dedicating approximately [     ] to developing
        the AOL Voice Portal.  This estimate anticipates I) that the functional
        "depth" and complexity of the relevant applications will be reasonably
        bounded by both parties to work within the [     ] window, ii) that the
        applications are developed in [     ] (not [     ]), and iii) that the
        system is deployed on [     ] ports with a second [     ]-port VRU
        deployed for N+1 redundancy.

     .  Speechworks anticipates that developing the [     ] service in a [     ]
        environment would add [     ]% to the development resources required
        for the task, and would add [     ] to the duration of work.

     .  Speechworks anticipates that deploying the [     ] service on
        approximately [     ] ports would add [     ] to the project, although
        due to parallel work would not slow the deployment by more than [     ]
        to [     ] [     ].

IX.  Consideration.

     As compensation for building the [     ] AOL Voice Portal, AOL shall
provide to  Speechworks payments totalling $[     ], payable:

     .  [     ] invoiced within 10 days after the Effective Date
     .  [     ] upon a mutually-agreed upon midpoint milestone
     .  [     ] upon completion of the work by Speechworks

      In the event that the scope of [     ] changes (including, as outlined
above, the option to deploy on more ports or to develop in [     ]), the
parties will mutually agree to a new scope and Speechworks will commit the
resources necessary to develop the revised [     ] service; provided, however,
that in any event SpeechWorks shall provide to AOL, beginning at the time that
work under any definitive Statement of Work for Phase 1 begins, with up to
[     ] of service at a rate of $[     ].  Further, based on the revisions to
the scope, the consideration outlined above will be adjusted as follows:

     .  If Speechworks commits fewer resources the consideration will be
reduced by a pro-rata amount (which will be calculated by dividing the
estimated resources of the new scope by the estimated resources of the [     ]
scope outlined herein and multiplying by the total consideration outlined
herein), or

                                     C-12
<PAGE>

     .  If Speechworks commits greater resources the consideration will be
increased by a pro-rata amount (which will be calculated by dividing the
estimated resources of the new scope by the estimated resources of the [     ]
scope outlined herein and multiplying by the total consideration outlined
herein).

  AOL shall pay Speechworks the full amount due at each milestone, regardless of
whether AOL launches the portal.
Hardware Platform

For planning purposes, SpeechWorks recommends that AOL proceed with the hardware
platform proposed by [     ] in a 5/12/00 e-mail from [     ] of [     ] to [
] of [     ].  The configuration outlined in this e-mail was as follows:

-  [     ], [     ], [     ]
-  [     ]
-  [     ]

Specific hardware will be determine in the Specification Phase of the project.

classification shall be made.

hereunder shall be performed by remote access unless SpeechWorks and AOL
mutually agree that on-site service at AOL's site is required in which event AOL

cost or difficulty of SpeechWorks providing such services.

2.10  Additional Services. If AOL requests, materials or services for the

lodging and related expenses, and any other reasonable expenses incurred by
SpeechWorks in providing such materials and service; provided that all travel,
lodging and related expenses, and any other expenses in excess of $1,000, if not

                              Annex 1 to Exhibit D
                          Description of Support Plan



1.  Error Corrections.  Upon receipt of notice(s) from AOL specifying Errors in
the Licensed Software, SpeechWorks will resolve the Errors according to the
following Severity Levels:

     (a)  Level 1 Errors: SpeechWorks will work with AOL on a [     ], [     ]
                    basis, will begin working with AOL's system administration
                    group member(s) within [     ] of the notification, and will
                    [     ] to resolve the Level 1 Error as quickly as possible.
                    SpeechWorks shall be deemed to have "resolved" a Level 1
                    Error if [     ] that the Error has been corrected or
                    reduced in scope to a Level 2, 3 or 4 Error.

     (b)  Level 2 Errors: SpeechWorks will exert commercially reasonable efforts
                    to resolve the Level 2 Error as quickly as possible.  If
                    such Error is not resolved within [     ], SpeechWorks will,
                    at AOL's option, work with AOL's system administration group
                    member(s) to resolve such Error on a [     ], [     ] basis
                    until it is resolved.  SpeechWorks shall be deemed to have
                    "resolved" a Level 2 Error if [     ] that the Error has
                    been corrected or reduced in scope to a Level 3 or 4 Error.

     (c)  Level 3 Errors: SpeechWorks will exert commercially reasonable
                    efforts to resolve the Level 3 Error within [     ].  If
                    such Error is not resolved within [     ], SpeechWorks will
                    exert commercially reasonable efforts to resolve the Error
                    as quickly as possible.  SpeechWorks shall be deemed to have
                    "resolved" a Level 3 Error if [     ] that the Error has
                    been corrected or reduced in scope to a Level 4 Error.

     (d)  Level 4 Errors: SpeechWorks will exert commercially reasonable
                    efforts to correct Level 4 Errors in the next standard
                    Update of the Licensed Software, or earlier at their sole
                    discretion.

2.    Escalation Procedure.

     (a)  Level 1 Errors: Should SpeechWorks be unable to resolve a Level 1
                    Error within [     ] after notification, the appropriate
                    second level managers from AOL and SpeechWorks shall meet by
                    teleconference and thoroughly discuss the current status and
                    resolution plan.  From that point until the Error is
                    resolved, SpeechWorks will provide an appropriate AOL
                    manager every [     ] an evaluation of the existing Error
                    resolution efforts and an estimate resolution time.  Should
                    SpeechWorks be unable to resolve a Level 1 Error within [
                    ] after notification, the appropriate third level managers
                    from AOL and SpeechWorks shall jointly review the status of
                    the Situation, and every [     ] thereafter until the Error
                    is resolved.  Should SpeechWorks be unable to resolve a
                    Level 1 Error within [     ] after notification, the
                    appropriate fourth level managers from AOL and SpeechWorks
                    shall jointly review the status of the Situation, and every
                    [     ] thereafter until the Error is resolved.

                                      D-7

                    evaluation of the existing Error resolution efforts and an
                    estimate resolution time.  Should SpeechWorks be unable to
                    resolve a Level 2 Error within [     ] after notification,
                    the appropriate second level managers from AOL and

Services under Section 2.1 of Exhibit D after the [     ] of the Effective Date,
AOL may purchase Versions at SpeechWorks' standard list prices therefor (except
that AOL shall be provided Versions for no additional charge if AOL has paid
SpeechWorks' then-current standard maintenance and support fees for maintenance
and support services during each [     ] period following the end of the

collectively as the "Product").

B.   Depositor desires to avoid disclosure of its proprietary technology except

C.   The availability of the proprietary technology of Depositor is critical to

to provide for the retention, administration and controlled access of certain
proprietary technology materials of Depositor.

E.   The parties desire this Agreement to be supplementary to the License

1.1  OBLIGATION TO MAKE DEPOSIT.  Upon the signing of this Agreement by the
parties, including the signing of the Acceptance Form, Depositor shall deliver
to DSI the proprietary technology and other materials ("Deposit Materials")
required to be deposited by the License Agreement or, if the License Agreement
does not identify the materials to be deposited with DSI, then such materials
will be identified on an Appendix 1.  If Appendix 1 is applicable, it is to be
prepared and signed by Depositor and preferred Beneficiary.  DSI shall have no
obligation with respect to the preparation, signing or delivery of Appendix 1.

1.2  IDENTIFICATION OF TANGIBLE MEDIA.  Prior to the delivery of the Deposit
Materials to DSI, Depositor shall conspicuously label for identification each
document, magnetic tape, disk, or other tangible media upon which the Deposit
Materials are written or stored.  Additionally, Depositor shall complete
Appendix 2 to this Agreement by listing each such tangible media by the item
label description, the type of media and the quantity.  The Appendix 2 must be
signed by Depositor and delivered to DSI with the Deposit Materials.  Unless and
until Depositor makes the initial deposit with DSI, DSI shall have no obligation
with respect to this Agreement, except the obligation to notify the parties
regarding the status of the deposit account as required in Section 2.2 below.

                                      F-1
<PAGE>

1.3  DEPOSIT INSPECTION.  When DSI receives the Deposit Materials and the
Appendix 2, DSI will conduct a deposit inspection by visually matching the
labeling of the tangible media containing the Deposit Materials to the item
descriptions and quantity listed n the Appendix 2.  In addition to the deposit
inspection, Preferred Beneficiary may elect to cause a verification of the
Deposit Materials in accordance with Section 1.6 below.

1.4  ACCEPTANCE OF DEPOSIT.  At completion of the deposit inspection, if DSI
determines that the labeling of the tangible media matches the item descriptions
and quantity on Appendix 2, DSI will date and sign the Appendix 2 and mail a
copy thereof to Depositor and Preferred Beneficiary.  If DSI determines that the
labeling does not match the item descriptions or quantity on the Appendix 2, DSI
will (a) note the discrepancies in writing on the Appendix 2; (b) date and sign
the Appendix 2 with the exceptions noted; and (c) mail a copy of the Appendix 2
to Depositor and Preferred Beneficiary.  DSI's acceptance of the deposit occurs
upon the signing of the Appendix 2 by DSI.  Delivery of the signed Appendix 2 to
Preferred Beneficiary is Preferred Beneficiary's notice that the Deposit
Materials have been received and accepted by DSI.

   (a)  Depositor lawfully possesses all of the Deposit Materials deposited with
DSI;

materials identified either in the License Agreement or Appendix 1, as the case
may be; and

   (e)  The Deposit Materials are readable and useable in their current form or,
if the Deposit Materials are encrypted, the decryption tools and decryption keys
have also been deposited.

1.6  VERIFICATION.  Preferred Beneficiary shall have the right, at Preferred
Beneficiary's expense, to cause a verification of any Deposit Materials.  A
verification determines, in different levels of detail, the accuracy,
completeness, sufficiency and quality of the Deposit Materials.  If a
verification is elected after the Deposit Materials have been delivered to DSI,
then only DSI, or at DSI's election an independent person or company selected
and supervised by DSI and who has signed a confidentiality agreement with terms
and conditions substantially similar to those set forth in Section 2.1, in which
Depositor is named as a third party beneficiary, may perform the verification.
Such verification may be requested once per Appendix 2, no later than thirty
(30) days after delivery thereof to DSI by Depositor.  Depositor may at its
discretion designate a representative to be present at the verification.

1.7  DEPOSIT UPDATES.  Unless otherwise provided by the License Agreement,
Depositor shall update the Deposit Materials within 60 days of each release of a
new version of the Product to be delivered under the License Agreement.  Such
updates will be added to the existing deposit.  All deposit updates shall be
listed on a new Appendix 2 and the new Appendix 2 shall be signed by Depositor.
Each Appendix 2 will be held and maintained separately within the escrow
account.  An independent record will be created which will document the activity

Agreement to the Deposit Materials shall include the initial Deposit Materials
and any updates.

exchanged only on written instructions signed by Depositor and Preferred
Beneficiary, or as otherwise provided in this Agreement.
