and shall fail to cure or substantially cure such default within ninety (90)
days after written notice thereof;

            (b) becomes bankrupt, insolvent, or dissolves provided in the case
of an involuntary bankruptcy the involved party shall have 60 days to dismiss

promotion of the sale of the Products and/or the support of the Products,
including but not limited to fulfillment of the Licensee's obligations under
Section 4.2(b) above.

            If Axcelis so elects, it shall give the Licensee written notice of
termination, specifying the cause and the effects thereof in accordance with
this Section 8.2. In the event that Axcelis elects to terminate its license
hereunder, the Licensee shall have the right to refer the matter to arbitration
in accordance with Section 9.7, in which case there shall be no effect on this
agreement until a decision has been issued from arbitration and the cure period
described in Section 9.7, if applicable, shall have expired. Upon any final
termination of this license, the Licensee shall immediately return any and all
hard copies of Technical Information to Axcelis.

      9. Miscellaneous.

            9.1. Confidentiality.

            (a) General. Except as may be mutually agreed by the parties and as
provided in Section 9.1(b), all confidential or proprietary information
disclosed by one party to the other in connection with the transactions proposed
in this Agreement and the negotiations between such parties shall be subject to
the terms of a Confidential Disclosure Agreement dated as of August 13, 2003
between Licensee and Axcelis.

            (b) Technical Information. The Technical Information to be furnished
by Axcelis hereunder is confidential and secret, and title to all such Technical
Information shall remain vested in Axcelis, subject to the exclusive license
granted hereunder. Each of the parties shall preserve and protect the
confidential nature of the Technical Information and shall not disclose the
Technical Information to

                                       8
<PAGE>

any third parties without the written consent of the other party except
suppliers, subcontractors and customers to the extent necessary to enable the
party to manufacture, use and sell the Products in accordance with the license
granted hereunder. Any and all drawings, blueprints, specifications and other
written materials produced by or at the request or direction of a party
disclosing Technical Information to any third party shall be marked with the
following language:

            "The technical information disclosed herein is the confidential
      property of Aspect Systems, Incorporated, as licensee of Axcelis
      Technologies, Inc. and is issued in confidence for engineering information
      only. It may not be reproduced or used in any way without an express
      written license from Aspect Systems Incorporated."

            (c) Liability for Disclosure. The disclosures permitted under
Section 9.1(c) above shall not relieve either party of its obligation to
maintain the confidentiality of the Technical Information, and each of the
parties shall be liable for any unauthorized disclosure by it or by those to
whom such party has made any disclosure.

            9.2. Assignment. Until the license granted hereunder is fully-paid,
the Licensee shall not be entitled to sublicense, transfer or otherwise assign
(including any assignment by merger or other operation of law) its rights or
delegate its obligations under this Agreement without the prior written approval
of Axcelis, except that (1) the Licensee may assign its rights and obligations
hereunder to an Affiliate of the Licensee existing on the date hereof, provided
advance notice thereof is provided to Axcelis and (2) the Licensee shall have
the right to subcontract the manufacture of parts and components for the
Products from time to time.

            9.3. Entire Agreement. The terms and provisions of this Agreement
constitute the entire agreement between the parties with respect to the subject
matter hereof. This Agreement shall supersede all previous communications,
either oral or written, between the parties with respect to the subject matter
hereof, including but not limited to the letter of intent dated September 25,
2003, but excluding the Confidential Disclosure Agreement dated August 13, 2003,
except as provided above. No agreement or understanding varying or extending
this Agreement shall be binding upon either party unless in writing signed by a
duly authorized officer or representative thereof.

            9.4. Non-Waiver of Rights and Disclaimer of Liability. Failure of
either party to enforce any of the provisions of this Agreement or any rights
with respect thereto or failure to exercise any election provided for herein
(except as expressly otherwise provided herein) shall in no way be considered a
waiver of such provisions, rights or elections or in any way to affect the
validity of this Agreement. The failure of either party to enforce any of said
provisions, rights or elections shall not preclude or prejudice such party from
later enforcing or exercising the same or any other provisions, rights, or
elections which it may have under this Agreement.

            9.5. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, all of which
shall constitute one and the same agreement.

            9.6. Disclaimer of Agency. This Agreement shall not constitute
either party the legal agent of the other, nor shall either party have the right
or authority to assume, create, or incur any liability or any obligation of any
kind, express or implied, against or on behalf of the other.

            9.7. Arbitration. Any and all disputes or differences between the
parties pertaining to or arising out of this Agreement, or the breach thereof,
shall be settled by arbitration to be held in Boston, Massachusetts in
accordance with the rules of the American Arbitration Association in effect upon
the date that either party serves notice upon the other party of a demand for
arbitration. The dispute shall be arbitrated by one arbitrator selected by
agreement of both parties; provided, however, in the event the parties cannot
agree upon an arbitrator, the arbitrator shall be appointed by the American
Arbitration

                                       9

Association. The award rendered by the arbitrator shall be final, binding upon
the parties, and enforceable by any court of competent jurisdiction.

      If a dispute arises as to whether or not Axcelis is entitled to terminate
this Agreement under Section 8.2 and arbitration is initiated to resolve such
dispute which determines that Axcelis does have the right to terminate this
Agreement, the Licensee shall have ninety (90) days from the date of the
arbitration decision to rectify the events causing such termination right
consistent with the arbitration decision and remove the grounds for termination.

            9.8. Notices. All notices for all purposes under this Agreement
shall be deemed to have been sufficiently addressed when, if given to Axcelis,
addressed to:

      Chief Executive Officer
      Axcelis Technologies, Inc.
      108 Cherry Hill Drive
      Beverly, Massachusetts 01915 U.S.A.

      or when, if given to the Licensee, addressed to:

      President
      Aspect Systems, Incorporated
      375 E. Elliot Road, Suite 6
      Chandler, AZ 85225

      and if sent by registered mail with return receipt requested. The date of
posting shall be deemed to be the date on which such notice or request has been
given or served. The parties may give written notice of change of address by
mail or by facsimile and, after notice of such change has been received, any
notice or request shall thereafter be given to such party as above provided at
such changed address.

            9.9. Force Majeure. Performance by the parties under this Agreement
shall be subject to, and no party shall have liability for delays, failure to
deliver, or cancellation due to events that cannot be anticipated at the time of
the signing of this Agreement, which events neither the occurrence nor aftermath
of which are avoidable or surmountable with reasonable effort by the affected
party. Such events shall include, but not be limited to, war, insurrection,
rebellion, fire, theft, accident, flood, earthquake, Act of God, strike,
slow-down, labor dispute, transportation delay, embargo, and governmental act,
regulation or request. The affected party shall promptly notify the other party
if performance hereunder is delayed due to events covered by this paragraph. The
parties agree to open, frank and serious discussions in connection with such
delay. Time for performance under this Agreement shall be extended for a period
equal to the period of delay caused by such events. In the event such period of
delay extends beyond one hundred twenty (120) days, either party may terminate
this Agreement upon giving notice to the other party as provided herein

            9.10. Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of Massachusetts,
United States of America. If any provisions of this Agreement shall be invalid
under the laws of a particular state, country or jurisdiction where used, then
it is agreed that the whole agreement shall not be invalid but it shall be
construed as if not containing such invalid provision and the rights and
obligations of the parties shall be construed and enforced accordingly.

                                    EXHIBIT B
                              WORK LETTER AGREEMENT

      This Work Letter Agreement ("Work Letter") is executed simultaneously with
that certain First Amendment (the "Lease") between Aspect Systems, Inc., as
"Tenant", and TEACHERS INSURANCE AND ANNUITY ASSOCIATION OF AMERICA, a New York
corporation, as "Landlord", relating to demised premises ("Premises") at the
building commonly known as EAST VALLEY COMMERCE CENTER (the "Building"), which
Premises are more fully identified in the Lease. Capitalized terms used herein,
unless otherwise defined in this Work Letter, shall have the respective meanings
ascribed to them in the Lease.

      For and in consideration of the agreement to lease the Premises and the
mutual covenants contained herein and in the Lease, Landlord and Tenant hereby
agree as follows:

      1. Tenant's Initial Plans; the Work. Tenant desires Landlord to perform
certain leasehold improvement work in the Premises in substantial accordance
with the plan or plans (collectively, the "Initial Plan") to be prepared by
Aspect Systems, Inc. Not later than March 15, 1999, Tenant shall furnish to
Landlord such additional plans, drawings, specifications and finish details as
Landlord may reasonably request to enable Landlord's architects and engineers to
prepare mechanical, electrical and plumbing plans and to prepare the Working
Drawings, including a final telephone layout and special electrical connection
requirements, if any. All plans, drawings, specifications and other details
describing the Work which have been or are hereafter furnished by or on behalf
of Tenant shall be subject to Landlord's approval, which Landlord agrees shall
not be unreasonably withheld. Landlord shall not be deemed to have acted
unreasonably if it withholds its approval of any plans, specifications, drawings
or other details or of any Additional Work (as defined in Paragraph 7 below)
because, in Landlord's reasonable opinion, the work, as described in any such
item, or the Additional Work, as the case may be: (a) is likely to adversely
affect Building systems, the structure of the Building or the safety of the
Building and/or its occupants; (b) might impair Landlord's ability to furnish
services to Tenant or other tenants in the Building; (c) would increase the cost
of operating the Building; (d) would violate any governmental laws, rules or
ordinances (or interpretations thereof); (e) contains or uses hazardous or toxic
materials or substances; (f) would adversely affect the appearance of the
Building, (g) might adversely affect another tenant's premises; (h) is
prohibited by any ground lease affecting the Building or any mortgage, trust
deed or other instrument encumbering the Building, or (i) is likely to be
substantially delayed because of unavailability or shortage of labor or
materials necessary to perform such work or the difficulties or unusual nature
of such work. The foregoing reasons, however, shall not be the only reasons for
which Landlord may withhold its approval, whether or not such other reasons are
similar or dissimilar to the foregoing. Neither the approval by Landlord of the
Work or Initial Plan or any other plans, drawings, specifications or other items
associated with the Work nor Landlord's performance, supervision or monitoring
of the Work shall constitute any warranty by Landlord to Tenant of the adequacy
of the design for Tenant's intended use of the Premises, Landlord shall be
entitled to a payment of 5% of the cost associated with the completion of
Tenant's buildout, which cost shall include architectural and engineering and
similar fees and all costs associated with the construction of the space as
charged by the general contractor selected to perform the work This payment is
for the coordination and day to day supervision performed by Landlord's staff in
completing Tenant's buildout. This payment will be part of the Tenant Allowance
package.

      2. Working Drawings. If necessary for the performance of the Work and not
included as part of the Initial Plan attached hereto, Landlord shall prepare or
cause to be prepared final working drawings and specifications for the Work (the
"Working Drawings") based on and consistent with the Initial Plan and the other
Plans, drawings, specifications, finish details and other information furnished
by Tenant to Landlord and approved by Landlord pursuant to Paragraph 1 above. So
long as the Working Drawings are consistent with the Initial Plan, Tenant shall
approve the Working Drawings within three (3) days after receipt of same from
Landlord by initialing and returning to Landlord each sheet of the

<PAGE>

Working Drawings or by executing Landlord's approval form then in use, whichever
method of approval Landlord may designate.

      3. Performance of the Work; Allowance. Except as hereinafter provided to
the contrary, Landlord shall cause the performance of the Work using (except as
may be stated or shown otherwise in the Working Drawings) building standard
materials, quantities and procedures then in use by Landlord ("Building
Standards"). Landlord shall pay for a portion of the "Cost of Work" (as defined
below) in an amount not to exceed $51,200.00 (such amount being $10.00 per
rentable square foot of the Premises which is to be improved, as described in
the Working Drawings) (the "Allowance"), and Tenant shall pay for the entire
Cost of the Work in excess of the Allowance. Tenant shall not be entitled to any
credit, abatement or payment from Landlord in the event that the amount of the
Allowance specified above exceeds the Cost of the Work. For purposes of this
Agreement, the term "Cost of the Work" shall mean and include any and all costs
and expenses of the Work, including, without limitation, the cost of the Working
Drawings and of all labor (including overtime) and materials constituting the
Work.

      4. Payment. Prior to commencing the Work, Landlord shall submit to Tenant
a written statement of the total Cost of the Work (which shall include the
amount of any overtime projected as necessary to substantially complete the Work
by the Commencement Date specified in the Lease) as then known by Landlord, and
such statement shall indicate the amount, if any, by which the total Cost of the
Work exceeds the Allowance (the "Excess Costs"). Tenant agrees, within three (3)
days after submission to it of such statement, to execute and deliver to
Landlord, in the form then in use by Landlord, an authorization to proceed with
the Work, and Tenant shall also then pay to Landlord an amount equal to the
Excess Costs. No Work shall be commenced until Tenant has fully complied with
the preceding provisions of this Paragraph 4. In the event, and each time, that
any change order by Tenant, unknown field condition, delay caused by acts beyond
Landlord's control or other event or circumstance causes the Cost of the Work to
be increased after the time that Landlord delivers to Tenant the aforesaid
initial statement of the Cost of the Work, Landlord shall deliver to Tenant a
revised statement of the total Cost of the Work, indicating the revised
calculation of the Excess Costs, if any. Within three (3) days after submission
to Tenant of any such revised statement, Tenant shall pay to Landlord an amount
equal to the Excess Costs, as shown in such revised statement, less the amounts
previously paid by Tenant to Landlord on account of the Excess Costs, and
Landlord shall not be required to proceed further with the Work until Tenant has
paid such amount. Delays in the performance of the Work resulting from the
failure of Tenant to comply with the provisions of this Paragraph 4 shall be
deemed to be delays caused by Tenant.

      5. Substantial Completion. Landlord shall cause the Work to be
"substantially completed" on or before the scheduled date of commencement of the
term of the Lease as specified in Section 1.05 of the Lease, subject to delays
caused by strikes, lockouts, boycotts or other labor problems, casualties,
discontinuance of any utility or other service required for performance of the
Work, unavailability or shortages of materials or other problems in obtaining
materials necessary for performance of the Work or any other matter beyond the
control of Landlord (or beyond the control of Landlord's contractors or
subcontractors performing the Work) and also subject to "Tenant Delays" (as
defined and described in Paragraph 6 of this Work Letter). The Work shall be
deemed to be "substantially completed" for all purposes under this Work Letter
and the Lease if and when Landlord's architect issues a written certificate to
Landlord and Tenant, certifying that the Work has been substantially completed
(i.e., completed except for "punchlist" items listed in such architect's
certificate) in substantial compliance with the Working Drawings, or when Tenant
first takes occupancy of the Premises, whichever first occurs. If the Work is
not deemed to be substantially completed on or before the scheduled date of the
commencement of the term of the Lease as specified in Section 1.05 of the Lease,
(a) Landlord agrees to use reasonable efforts to complete the Work as soon as
practicable thereafter, (b) the Lease shall remain in full force and effect, (c)
Landlord shall not be deemed to be in breach or default of the Lease or this
Work Letter as a result thereof and Landlord shall have no liability to Tenant
as a result of any delay in occupancy (whether for

                                       2
<PAGE>

damages, abatement of Rent or otherwise), and (d) except in the event of Tenant
Delays, and notwithstanding anything contained in the Lease to the contrary, the
Commencement Date of the Lease Term as specified in Section 1.05 of the Lease
shall be extended to the date on which the Work is deemed to be substantially
completed and the Expiration Date of the Lease Term as specified in Section 1.06
of the Lease shall be extended by an equal number of days. At the request of
either Landlord or Tenant in the event of such extensions in the commencement
and expiration dates of the term of the Lease, Tenant and Landlord shall execute
and deliver an amendment to the Lease reflecting such extensions. Landlord
agrees to use reasonable diligence to complete all punch1ist work listed in the
aforesaid architect's certificate promptly after substantial completion.

      6. Tenant Delays. There shall be no extension of the scheduled
commencement or expiration date of the term of the Lease (as otherwise
permissibly extended under Paragraph 5 above) if the Work has not been
substantially completed on said scheduled commencement date by reason of any
delay attributable to Tenant ("Tenant Delays"), including without limitation:

            (i) the failure of Tenant to furnish all or any plans, drawings,
specifications, finish details or the other information required under Paragraph
1 above on or before the date stated in Paragraph 1;

            (ii) the failure of Tenant to grant approval of the Working Drawings
within the time required under Paragraph 2 above;

            (iii) the failure of Tenant to comply with the requirements of
Paragraph 4 above;

            (iv) Tenant's requirements for special work or materials, finishes,
or installations other than the Building Standards or Tenant's requirements for
special construction staging or phasing;

            (v) the performance of any Additional Work (as defined in Paragraph
7 below) requested by Tenant or the performance of any work in the Premises by
any person, firm or corporation employed by or on behalf of Tenant, or any
failure to complete or delay in completion of such work; or

            (vi) any other act or omission of Tenant that causes a delay.

      7. Additional Work. Upon Tenant's request and submission by Tenant (at
Tenant's sole cost and expense) of the necessary information and/or plans and
specifications for work other than the Work described in the Working Drawings
("Additional Work") and the approval by Landlord of such Additional Work, which
approval Landlord agrees shall not be unreasonably withheld, Landlord shall
perform such Additional Work, at Tenant's sole cost and expense, subject,
however, to the following provisions of this Paragraph 7. Prior to commencing
any Additional Work requested by Tenant, Landlord shall submit to Tenant a
written statement of the cost of such Additional Work, which cost shall include
a fee payable to Landlord in the amount of 15% of the total cost of such
Additional Work as compensation to Landlord for monitoring the Additional Work
and for administration, overhead and field supervision associated with the
Additional Work and an additional charge payable to Landlord in the amount of 5%
of the total Cost of the Additional Work as compensation for Landlord's general
conditions (such fee and additional charge being hereinafter referred to
collectively as "Landlord's Additional Compensation"), and, concurrently with
such statement of cost, Landlord shall also submit to Tenant a proposed tenant
extra order (the "TEO") for the Additional Work in the standard form then in use
by Landlord.

      Tenant shall execute and deliver to Landlord such TEO and shall pay to
Landlord the entire cost of the Additional Work, including Landlord's Additional
Compensation (as reflected in Landlord's statement of such cost), within five
(5) days after Landlord's submission of such statement and TEO to Tenant. If
Tenant fails to execute or deliver such TEO or pay the entire cost of such
Additional Work

                                       3
<PAGE>

within such 5-day period, then Landlord shall not be obligated to do any of the
Additional Work and may proceed to do only the Work, as specified in the Working
Drawings.

      8. Tenant Access. Landlord, in Landlord's reasonable discretion and upon
request by Tenant, may grant to Tenant a license to have access to the Premises
prior to the date designated in the Lease for the commencement of the term of
the Lease to allow Tenant to do other work required by Tenant to make the
Premises ready for Tenant's use and occupancy (the "Tenant's Pre-Occupancy
Work"). It shall be a condition to the grant by Landlord and continued
effectiveness of such license that:

            (a) Tenant shall give to Landlord a written request to have such
access to the Premises not less than five (5) days prior to the date on which
such access will commence, which written request shall contain or shall be
accompanied by each of the following items, all in form and substance reasonably
acceptable to Landlord: (i) a detailed description of and schedule for Tenant's
Pre-Occupancy Work; (ii) the names and addresses of all contractors,
subcontractors and material suppliers and all other representatives of Tenant
who or which will be entering the Premises on behalf of Tenant to perform
Tenant's Pre-Occupancy Work or will be supplying materials for such work, and
the approximate number of individuals, itemized by trade, who will be present in
the Premises; (iii) copies of all contracts, subcontracts and material purchase
orders pertaining to Tenant's Pre-Occupancy Work; (iv) copies of all plans and
specifications pertaining to Tenant's Pre-Occupancy Work; (v) copies of all
licenses and permits required in connection with the performance of Tenant's
Pre-Occupancy Work; (vi) certificates of insurance (in amounts satisfactory to
Landlord and with the parties identified in, or required by, the Lease named as
additional insureds) and instruments of indemnification against all claims,
costs, expenses, damages and liabilities which may arise in connection with
Tenant's Pre-Occupancy Work; and (vii) assurances of the ability of Tenant to
pay for all of Tenant's Pre-Occupancy Work and/or a letter of credit or other
security deemed appropriate by Landlord securing Tenant's lien-free completion
of Tenant's Pre-Occupancy Work.

            (b) Such pre-term access by Tenant and its representatives shall be
subject to scheduling by Landlord.

            (c) Tenant's employees, agents, contractors, workmen, mechanics,
suppliers and invitees shall work in harmony and not interfere with Landlord or
Landlord's agents in performing the Work and any Additional Work in the
Premises, Landlord's work in other premises and in common areas of the Building,
or the general operation of the Building. If at any time any such person
representing Tenant shall cause or threaten to cause such disharmony or
interference, including labor disharmony, and Tenant fails to immediately
institute and maintain such corrective actions as directed by Landlord, then
Landlord may withdraw such license upon twenty-four (24) hours' prior written
notice to Tenant.

            (d) Any such entry into and occupancy of the Premises by Tenant or
any person or entity working for or on behalf of Tenant shall be deemed to be
subject to all of the terms, covenants, conditions and provisions of the Lease,
specifically including the provisions of Section IX thereof (regarding Tenant's
improvements and alterations to the Premises), and excluding only the covenant
to pay Rent. Landlord shall not be liable for any injury, loss or damage which
may occur to any of Tenant's Pre-Occupancy Work made in or about the Premises or
to property placed therein prior to the commencement of the term of the Lease,
the same being at Tenant's sole risk and liability. Tenant shall be liable to
Landlord for any damage to the Premises or to any portion of the Work or
Additional Work caused by Tenant or any of Tenant's employees, agents,
contractors, workmen or suppliers. In the event that the performance of Tenant's
Pre-Occupancy Work causes extra costs to Landlord or requires the use of
elevators during hours other than ________a.m. to _______p.m. on Monday through
Friday (excluding holidays) or of other Building services, Tenant shall
reimburse Landlord for such extra cost, and/or shall pay Landlord for such
elevator service or other building services at Landlord's standard rates then in
effect.
