	 	3.	 	Section 2.01(c) of the PLA shall be amended to read as follows:

LUCENT/ASPECT PROPRIETARY

 

	 	4.	 	ASPECT agrees to forego and relinquish any rights that ASPECT
previously had under the PLA to elect not to extend the LIMITED PERIOD

2007 payable on or before March 15, 2007.”

	 	5.	 	The payments that ASPECT is required to make to LUCENT under
paragraph 4 of this Letter Agreement shall be due even if ASPECT
exercises its right to terminate all or a portion of the licenses and
rights granted to it under Section 3.02(a) of the PLA or any other
Section of the PLA.

	 	6.	 	In the event that ASPECT fails to make the calendar year 2003
payment required on or before July 3, 2003 by paragraph 3 of this
Letter Agreement, this entire Letter Agreement shall be null and void
and the rights and obligations of the parties under the PLA shall
continue as specified in the PLA.

	 	7.	 	Any payments made by ASPECT under this Letter Agreement are
non-refundable.

	 	8.	 	Section 2.01(e) of the PLA shall be amended to read as follows:

“Overdue payments hereunder shall be subject to a late payment
charge calculated at an annual rate of six percentage points (6%)
over the prime rate or successive prime rates (as posted in New
York City) during delinquency. If the amount of such charge
exceeds the maximum permitted by law, such charge shall be reduced
to such maximum.”

	 	9.	 	ASPECT shall mean Aspect Communications Corporation, a California
corporation having an office at 1310 Ridder Park Drive, San Jose,
California 95131-2313. Any notice or other communication hereunder

            The Company hereby represents and warrants to Vista Fund and Vista
Partners that, except as set forth on the Schedule of Exceptions provided to
Vista Fund and Vista Partners (which exceptions shall be deemed to be
representations and warranties as if made hereunder):

            3.1 Existence; Qualification; Subsidiaries. The Company is duly
organized, validly existing and in good standing under the California General
Corporation Law and has full corporate power and authority to conduct its
business and own and operate its properties as now conducted, owned and
operated. The copies of the Articles of Incorporation and Bylaws of the Company
and all amendments thereto filed by the Company with the SEC prior to the date
of this Agreement are in full force and effect.

            3.2 Authorization, Noncontravention and Enforceability; Issuance of
Shares.

            (a) The Company has full power and authority and has taken all
required corporate and other action necessary to permit it to execute and
deliver this Agreement and to carry out the terms hereof and to issue and
deliver the Conversion Shares and the VEP Shares, and none of such actions will
(i) violate or conflict with any provision of the Articles of Incorporation of
the Company, the Bylaws of the Company or of any applicable law, regulation,
order, judgment or decree or rule of the Nasdaq National Market where the Common
Stock is listed, (ii) except as set forth on Schedule 3.2, result in the
material breach of or constitute a material default (or an event which, with
notice or lapse of time or both would constitute a default) under any agreement,
instrument or understanding to which the Company is a party or by which it is
bound, or (iii) result in or constitute a "change in control" under any
agreement, instrument or understanding to which the Company is a party or by

delivered by the Company and

                                       8
<PAGE>
constitutes a legal, valid and binding obligation of the Company, enforceable
against the Company in accordance with its terms, except to the extent limited
by applicable bankruptcy, insolvency, reorganization, moratorium and similar
laws of general application related to the enforcement of creditor's rights
generally (collectively "Creditors Rights Laws").

            (b) The Series B Shares have been duly authorized, validly issued,
are fully paid and are nonassessable. The Conversion Shares have been duly
authorized and reserved for issuance, and when issued and delivered upon
conversion of the Series B Shares, will be validly issued, fully paid and
nonassessable, and will be free of any and all Liens (other than any
restrictions on transfer under state and/or federal securities laws). The VEP
Shares have been duly authorized and reserved for issuance, and when issued and
delivered in accordance with this Agreement, will be validly issued, fully paid
and nonassessable, and will be free of any and all Liens (other than any
restrictions on transfer under state and/or federal securities laws). Neither
the issuance and delivery of the Conversion Shares or the VEP Shares is subject
to any preemptive right of any shareholder of the Company or to any right of
first refusal or other similar right in favor of any Person which has not been
waived.

            3.3 Capitalization. The Registration Statement, collectively with
the other filings made by the Company with the SEC prior to the date of this

appreciation rights, transfer restrictions (except restrictions imposed by
federal and state securities laws), Liens, currently effective rights of first

offer, antidilution provisions or any other preferential rights applicable to
the issuance and sale of securities of the Company or any of its Subsidiaries,
including, but not limited to, the Conversion Shares and the VEP Shares.

            3.4 Private Sale; No Shareholder Approval.

            (a) Assuming the accuracy of the representations of Vista Fund and
Vista Partners contained herein and any Vista Assignee, if applicable, neither

hereunder requires or will require registration under the Securities Act or any
state securities laws.

                                       9
<PAGE>

Subsidiaries' business which if decided adversely to any such Person could have
or reasonably be expected to have a Material Adverse Effect or prevent,
materially delay or materially impair the ability of the Company to consummate
the transactions contemplated by this Agreement.

VEP Shares, Vista Fund or Vista Partners, as applicable, shall deliver written
notice to the Company describing in reasonable detail the proposed transfer,
together with an opinion of counsel (Sullivan & Cromwell LLP or such other
counsel which, to the Company's reasonable satisfaction, is knowledgeable in
securities law matters), to the effect that such transfer may be effected
without registration of such shares under the Securities Act. Neither Vista Fund
nor Vista Partners, as applicable, shall consummate a

                                       12

consideration for the services Vista Fund, Vista Partners or their Affiliates
performed in structuring and arranging the transactions contemplated by this
Agreement, the Company will pay to Vista Partners (or its Affiliate) a
transaction fee equal to $3,000,000 (the "Closing Fee"), by wire transfer of
immediately available funds to an account specified in writing to the Company by
Vista Partners no later than two Business Days prior to the Closing. In
addition, on the earlier of (x) the Closing Date, and (y) the third business day
after this Agreement is terminated, unless this Agreement is terminated pursuant
to Section 7.5(b), the Company shall reimburse Vista Fund, Vista Partners or
their Affiliates for (i) the reasonable fees and expenses of Sullivan & Cromwell

contemplated by this Agreement, and (ii) all other reasonable fees and out of
pocket expenses incurred by Vista Fund, Vista Partners or their Affiliates in
connection with the transactions contemplated hereunder (including, without
limitation, fees and expenses of legal counsel, accountants or other
representatives). After the Closing, the Company agrees to reimburse Vista Fund,
Vista Partners or their Affiliates for all reasonable fees and expenses
(including reasonable

                                       21
<PAGE>
legal fees) incurred in connection with any future amendment to, waiver of or
the enforcement by Vista Fund or Vista Partners of any of its rights arising
under this Agreement. The parties' respective obligations to pay expenses
relating to the transaction contemplated by the Underwriting Agreement shall be
governed by the Underwriting Agreement.

            8.6 Amendment and Waiver. No amendment or waiver of any provision of
this Agreement shall be effective, unless the same shall be in writing and
signed by the Parties. No such waiver shall operate as a waiver of, or estoppel
with respect to, any subsequent or other failure. No failure by any Party to
take any action against any breach of this Agreement or default by any other
Party shall constitute a waiver of such Party's right to enforce any provision
hereof or to take any such action.

            8.7 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one agreement.

            8.8 Headings. The headings of the various sections of this Agreement
have been inserted for reference only and shall not be deemed to be a part of
this Agreement.

            8.9 Specific Performance. The Company, on the one hand, and Vista
Fund or Vista Partners, on the other hand, acknowledges that money damages may
not be a sufficient remedy for any breach of this Agreement. It is accordingly
agreed that the parties shall be entitled to seek specific performance and
injunctive relief as remedies for any such breach, these remedies being in
addition to any of the remedies to which they may be entitled at law or equity.

            8.10 Remedies Cumulative. Except as otherwise provided herein, the
remedies provided herein shall be cumulative and shall not preclude the
assertion by any Party hereto of any other rights or the seeking of any other
remedies against any other Party hereto.

            8.11 GOVERNING LAW. ALL ISSUES AND QUESTIONS RELATING TO THE
CONSTRUCTION, INTERPRETATION AND ENFORCEMENT OF THIS AGREEMENT SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF
CALIFORNIA, WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAWS OR CHOICE
OF LAW OF THE STATE OF CALIFORNIA OR ANY OTHER JURISDICTION WHICH WOULD RESULT
IN THE APPLICATION OF THE LAW OF ANY JURISDICTION OTHER THAN THE STATE OF
CALIFORNIA.

            8.12 No Third Party Beneficiaries. Except as specifically set forth
or referred to herein, nothing herein is intended or shall be construed to
confer upon any

                                       22
<PAGE>
person or entity other than the Parties and their successors or assigns, any
rights or remedies under or by reason of this Agreement.

            8.13 Severability. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction to be invalid,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

            8.14 Time of the Essence; Computation of Time. Time is of the
essence for each and every provision of this Agreement. Whenever the last day
for the exercise of any privilege or the discharge or any duty hereunder shall
fall upon a non-Business Day, the Party having such privilege or duty may
exercise such privilege or discharge such duty on the next succeeding Business
Day.
