that Former Employee is a “specified employee” within the meaning of Code Section 409A(a)(2)(B)(i)

3. CONFIDENTIALITY OBLIGATIONS DO NOT TERMINATE

     Former Employee acknowledges that any confidentiality, proprietary rights or nondisclosure
agreement(s) in favor of Tekelec which she may have entered into in connection with her employment
(collectively, the “Nondisclosure Agreement”) with Tekelec is understood to be intended to survive,
and does survive, any termination of such employment, and accordingly nothing in this Agreement
shall be construed as terminating, limiting or otherwise affecting any such Nondisclosure Agreement
or Former Employee’s obligations thereunder. Without limiting the generality of the foregoing, no
time period set forth in this Agreement shall

2

 

be construed as
shortening or limiting the term of any such Nondisclosure Agreement, which term shall continue
as set forth therein.

4. BENEFITS

     4.1 Life Insurance Continuation. In lieu of Tekelec’s continuation of Former
Employee’s life insurance benefits after the Termination Date, the Severance Allowance described in
Section 6.2 below has been increased by the amount of $1800.00. Any conversion or continuation of
life insurance after the Termination Date shall be at Former Employee’s sole expense in accordance
with the terms of applicable life insurance policy.

     4.2 Health Care Insurance Continuation. Tekelec (at its expense) will continue, for a
period of 18 months following the Termination Date, health care coverage including medical, dental
and vision coverage for Former Employee and her family members so long as they are “qualified
beneficiaries” (as such term is defined in the Consolidated Omnibus Budget Reconciliation Act of
1985 (“COBRA”)) entitled to COBRA continuation coverage, such coverage to be provided under
Tekelec’s group health plan(s) generally available during such period to employees participating in
such plan(s) and at levels and with coverage no greater than those provided to such Former Employee
as of the Termination Date. Thereafter, Former Employee (at her expense) may elect coverage under
a conversion health plan available under Tekelec’s group health plan(s) from Tekelec’s health
insurance carrier if and to the extent she is entitled to do so as a matter of right under federal
or state law.

     4.3 Other Benefit Plans. Except as otherwise expressly provided in this Section 4 or
as required by applicable law, Former Employee shall have no right to continue her participation in
any Tekelec benefit plan following such employee’s termination.

5. STOCK OPTIONS

     5.1 Outstanding Stock Options. Exhibit A hereto sets forth any and all outstanding
stock options, warrants and other rights to purchase capital stock or other securities of Tekelec
which have been previously issued to Former Employee and which are outstanding and vested as of the
date hereof. Except as specifically set forth in Section 5.2 below, nothing in this Agreement
shall alter or affect any of such outstanding stock options, warrants or rights or Former
Employee’s rights or responsibilities with respect thereto, including but not limited to Former
Employee’s rights to exercise any of her options, warrants or rights following the Termination
Date.

     5.2 Extension of Exercise Period. The parties acknowledge that in connection with the
filing of Tekelec’s Current Report on Form 8-K in February 2006, wherein Tekelec announced that it
would restate previously issued financial statements, Tekelec is prohibited by applicable
securities laws from issuing any shares of its common stock (hereinafter referred to as the
“restriction”) and accordingly, Former Employee is unable to exercise any of her stock options
until Tekelec becomes current in its financial reporting and the restriction lapses. In
consideration for Former Employee’s release of claims set forth herein, and her continuing
performance of her obligations under the Employment Separation Agreement (including but not

3

 

limited to Former Employee’s obligations under Sections 7 , 8, 10 and 11 thereof), Tekelec
agrees to extend the exercise period with respect to Former Employee’s nonstatutory stock options
(“NSOs”) totaling 323,752 shares as set forth on Exhibit A, for a limited period following the
lapse of the restriction to the extent indicated in footnotes 2 through 5 therein. Upon the
termination dates as specified therein, said options to the extent not exercised shall terminate
and expire for all purposes.

     5.3 No Guarantees of Exercisability or Value; No Other Changes.  Tekelec has not
extended the term of the Incentive Stock Option granted to Former Employee on January 18, 2002 for
20,000 shares (the “ISO”), has not promised Former Employee that the restriction will lapse prior
to the termination of the ISO, and Former Employee understands that there can be no assurance that
Former Employee will have the opportunity to exercise the ISO. Former Employee further
acknowledges that Tekelec has not guaranteed the value of any of Former Employee’s nonstatutory
stock options. Except as specifically set forth in Section 5.2 above and Exhibit A, the time
period through which Former Employee may exercise her vested stock options shall expire in
accordance with the terms of the stock option plans under which Former Employee’s options were
granted.

6. PAYMENTS TO FORMER EMPLOYEE

     6.1 Employee Compensation. Tekelec has paid or shall pay in 2006 within the time
period required by law, any and all salary and accrued but unpaid vacation and sick pay owed by
Tekelec to Former Employee up to and including the Termination Date other than any severance
payments owed to her under the terms of this Agreement and certain bonuses as described in this
Section 6.1(b)

          (a) Former Employee’s quarterly bonus due for the fourth quarter of 2005 (Q405) in the amount
of $12,852.00, and her MBO 2005 bonus due in the amount of $58,527.00 shall be paid at the same
time as such bonuses are paid to other similarly situated executive officers of Tekelec but in no
event later than the Termination Date.

          (b) The parties acknowledge that any bonuses due to Former Employee for the first quarter of
2006 (“Q106”) and the second quarter of 2006 (“Q206”) may not have been calculated and/or paid as
of the Termination Date. Tekelec agrees to pay Former Employee any bonus due for Q106 and Q206
under the 2006 Executive Officer Bonus Plan when such bonuses are calculated and paid to similarly
situated executive officers of Tekelec, but in any case on or before December 31, 2006, and further
agrees to waive the requirement that Former Employee must be in active status on the bonus payment
date(s) to receive her bonuses for Q106 and Q206 Former Employee understands that Tekelec has not
promised that any bonus will be payable under the terms of the Executive Officer Bonus Plan for
such periods.

     6.2 Severance Allowance. In consideration for the release by Former Employee set forth
herein (including the release of any and all claims Former Employee has or may have under the Age
Discrimination in Employment Act (“ADEA”) and Older Workers Benefit Protection Act (“OWBPA”)) and
Former Employee’s performance of her obligations under this Agreement

4

 

     (including but not limited to Former Employee’s obligations under Section 7 hereof), Former
Employee is entitled to receive, and Tekelec shall pay to Former Employee a Severance Allowance in
the aggregate gross amount of $648,033.00 (the “Severance Allowance”), less all applicable
withholding taxes. Such Severance Allowance shall be paid by direct deposit into Former Employee’s
bank account on file with Tekelec according to the following schedule: Fifty percent (50%) of the
Severance Allowance ($324, 016.50, less all applicable withholdings and deductions) shall be due
and payable on January 3, 2007, and the remainder of the Severance Allowance shall be due and
payable in six (6) equal monthly installments of $54,002.75 (less all applicable withholdings and
deductions), on February 2, 2007, March 2, 2007, April 3, 2007, May 2, 2007, June 4, 2007, and a
final payment on July 3, 2007. The parties specifically acknowledge and agree that Former
Employee has requested and Tekelec has agreed to accumulate and defer all installment payments of
the Severance Allowance that would otherwise be due during the first six (6) months following the
Termination Date in order to comply with Section 409A of the Internal Revenue Code

7. NON-COMPETITION AND NON-SOLICITATION

     7.1 Subject and in addition to Former Employee’s existing fiduciary duties as a former officer
and employee of Tekelec to the extent such continues under applicable law after Former Employee’s
Termination Date, provided that Tekelec has not breached any of the terms of this Agreement or any
other currently existing written agreements between Tekelec and Former Employee, Former Employee
agrees until the earlier of (i) the completion of the Severance Covered Period or (ii) such date as
Tekelec may terminate this Agreement for default hereunder:

          (a) Not to engage, either directly or indirectly, in any Competing Business Activity (as
defined below) or be associated with a Competing Business Entity (as defined below) as an officer,
director, employee, principal, consultant, lender, creditor, investor, agent or otherwise for any
corporation, partnership, company, agency, person, association or any other entity; provided,
however, that nothing contained herein shall prevent Former Employee from owning not more than 5%
of the common equity and not more than 5% of the voting power of, or lending not more than $25,000
to, any Competing Business Entity or any business engaged in a Competing Business Activity;
provided, further, that for purposes of this agreement, any equity ownership, voting control or
lending activity of Former Employee shall be deemed to include that of (i) any family member or
(ii) person or entity controlled by Former Employee;

          (b) Not to call upon or cause to be called upon, or solicit or assist in the solicitation of,
in connection with any Competing Business Entity or Competing Business Activity, any entity,
agency, person, firm, association, partnership or corporation that is a customer or account of
Tekelec, currently and/or during the Severance Covered Period, for the purpose of selling, renting,
leasing, licensing or supplying any product or service that is the same as, similar to or
competitive with the products or services then being sold or developed by Tekelec;

5

 

          (c) Not to enter into an employment or agency relationship with a Competing Business Entity or
involving a Competing Business Activity with any person who, at the time of such entry, is an
officer, director, employee, principal or agent of or with respect to Tekelec; and

          (d) Not to induce or attempt to induce any person described in Section 7.1(c) to leave her
employment, agency, directorship or office with Tekelec.

activity of a person or entity (other than Tekelec) involving the development, design, manufacture,
distribution, marketing, licensing, renting, leasing or selling within the Territory (as defined

services of Tekelec then in existence or under development. For purposes hereof, the Territory
shall include the United States of America, Canada, Central America, South America, Europe, Japan,
Australia, Singapore, China, India, the Russian Federation and such other countries in which
Tekelec then distributes, markets, licenses, rents, leases or sells its products or services. An
entity as a whole shall be deemed to be a Competing Business Entity if it has one or more business

renting, leasing or selling directly or indirectly within the Territory of products or services
which are the same as, similar to or competitive with products or services of Tekelec then being
sold or under development and if and only if the revenues derived directly or indirectly from
engaging in such business activities by such entity represent either more than 3% of the entity’s
revenues or at least $5 million in aggregate sales, or both, for the then-preceding 12-month
period.

     7.3 The parties acknowledge that the provisions and obligations set forth in this Section 7
are an integral part of this Agreement and that in the event Former Employee breaches any of the
provisions or obligations of this Section 7 or any other term, provision or obligation of this
Agreement, then Tekelec, in addition to any other rights or remedy it may have at law, in equity,
by statute or otherwise, shall be excused from its payment obligations to Former Employee under the
Severance Plan and this Agreement.

8. CONFIDENTIAL INFORMATION AND TRADE SECRETS

     8.1 Former Employee hereby recognizes, acknowledges and agrees that Tekelec is the owner of
proprietary rights in certain confidential sales and marketing information, programs, tactics,
systems, methods, processes, compilations of technical and non-technical information, records and
other business, financial, sales, marketing and other information and things of value. To the
extent that any or all of the foregoing constitute valuable trade secrets and/or confidential
and/or privileged information of Tekelec, Former Employee hereby further agrees as follows:

          (a) That, except with prior written authorization from Tekelec’s CEO, for purposes related to
Tekelec’s best interests, she will not directly or indirectly duplicate, remove, transfer, disclose
or utilize, nor knowingly allow any other person to duplicate, remove, transfer, disclose or
utilize, any property, assets, trade secrets or other things of value, including, but not limited
to, records, techniques, procedures, systems, methods, market research, new product plans and
ideas, distribution arrangements, advertising and promotional materials, forms,

6

 

patterns,
lists of past, present or prospective customers, and data prepared for, stored in, processed
by or obtained from, an automated information system belonging to or in the possession of Tekelec
which are not intended for and have not been the subject of public disclosure. Former Employee
agrees to safeguard all Tekelec trade secrets in her possession or known to her at all times so
that they are not exposed to, or taken by, unauthorized persons and to exercise her reasonable
efforts to assure their safekeeping. This subsection shall not apply to information that as of the
date hereof is, or as of the date of such duplication, removal, transfer, disclosure or utilization
(or the knowing allowing thereof) by Former Employee has (i) become generally known to the public
or competitors of Tekelec (other than as a result of a breach of this Agreement); (ii) been
lawfully obtained by Former Employee from any third party who has lawfully obtained such
information without breaching any obligation of confidentiality; or (iii) been published or
generally disclosed to the public by Tekelec. Former Employee shall bear the burden of showing
that any of the foregoing exclusions applies to any information or materials.

          (b) That all improvements, discoveries, systems, techniques, ideas, processes, programs and
other things of value made or conceived in whole or in part by Former Employee with respect to any
aspects of Tekelec’s current or anticipated business while an employee of Tekelec are and remain
the sole and exclusive property of Tekelec, and Former Employee has disclosed all such things of
value to Tekelec and will cooperate with Tekelec to insure that the ownership by Tekelec of such
property is protected. All of such property of Tekelec in Former Employee’s possession or control,
including, but not limited to, all personal notes, documents and reproductions thereof, relating to
the business and the trade secrets or confidential or privileged information of Tekelec has already
been, or shall be immediately, delivered to Tekelec.

     8.2 Former Employee further acknowledges that as the result of her prior service as an officer
and employee of Tekelec, she has had access to, and is in possession of, information and documents
protected by the attorney-client privilege and by the attorney work product doctrine. Former
Employee understands that the privilege to hold such information and documents confidential is
Tekelec’s, not hers personally, and that she will not disclose the information or documents to any
person or entity without the express prior written consent of the CEO or Board of Tekelec unless
she is required to do so by law.

     8.3 Former Employee’s obligations set forth in this Section 8 shall be in addition to, and not
instead of, Former Employee’s obligations under any written Nondisclosure Agreement.

9. ENFORCEMENT OF SECTIONS 7 AND 8

     Former Employee hereby acknowledges and agrees that the services rendered by her to Tekelec in
the course of her prior employment were of a special and unique character, and that breach by her
of any provision of the covenants set forth in Sections 7 and 8 of this Agreement will cause
Tekelec irreparable injury and damages. Former Employee expressly agrees that Tekelec shall be
entitled, in addition to all other remedies available to it whether at law or in equity, to
injunctive or other equitable relief to secure their enforcement.

7

 

     The parties hereto expressly agree that the covenants contained in Sections 7 and 8 hereof are
reasonable in scope, duration and otherwise; however, if any of the restraints provided in said
covenants are adjudicated to be excessively broad as to geographic area or time or otherwise,
said restraint shall be reduced to whatever extent is reasonable and the restraint shall be fully
enforced in such modified form. Any provisions of said covenants not so reduced shall remain in
full force and effect.

10. PROHIBITION AGAINST DISPARAGEMENT

     10.1 Former Employee agrees that for a period of two years following the Effective Date any
communication, whether oral or written, occurring on or off the premises of Tekelec, made by her or
on her behalf to any person or entity (including, without limitation, any Tekelec employee,
customer, vendor, supplier, any competitor, any media entity and any person associated with any
media) which in any way relates to Tekelec (or any of its subsidiaries) or to Tekelec’s or any of
its subsidiaries’ directors, officers, management or employees: (a) will be truthful; and (b) will
not, directly or indirectly, criticize, disparage, or in any manner undermine the reputation or
business practices of Tekelec or its directors, officers, management or employees. In response to
any inquiries from prospective employers of Former Employee, Tekelec will confirm dates of
employment, positions held, and that Former Employee resigned together with a statement that
Tekelec’s policies prevent Tekelec from providing additional information and that no negative
inferences should be drawn from Tekelec’s failure to do so.

     10.2 The only exceptions to Section 10.1 shall be: (a) truthful statements privately made to
(i) the CEO of Tekelec, (ii) any member of Tekelec’s Board, (iii) Tekelec’s auditors, (iv) inside
or outside counsel of Tekelec, (v) Former Employee’s counsel or (vi) Former Employee’s spouse; (b)
truthful statements lawfully compelled and made under oath in connection with a court or government
administrative proceeding; and (c) truthful statements made to specified persons upon and in
compliance with prior written authorization from Tekelec’s CEO or Board to Former Employee
directing her to respond to inquiries from such specified persons.

11. COOPERATION

     Former Employee agrees that for a period of five years commencing with the Effective Date she
will cooperate fully and reasonably with Tekelec in connection with any future or currently pending
matter, proceeding, litigation or threatened litigation: (1) directly or indirectly involving
Tekelec (which, for purposes of this section, shall include Tekelec and each of its current and
future subsidiaries, successors or permitted assigns); or (2) directly or indirectly involving any
director, officer or employee of Tekelec (with regard to matters relating to such person(s) acting
in such capacities with regard to Tekelec business). Such cooperation shall include making herself
available upon reasonable notice at reasonable times and places for consultation and to testify
truthfully (at Tekelec’s expense for reasonable, pre-approved out-of-pocket travel costs plus a
daily fee equal to one-twentieth of her monthly severance compensation under Section 6.2 hereof for
each full or partial day during which Former Employee makes herself so available which shall be
paid with reasonable promptness following Tekelec’s receipt of an invoice from Former Employee) in
any action as reasonably requested by

8

 

the CEO or the Board of Directors. Former Employee further
agrees to immediately notify Tekelec’s CEO in writing in the event that she receives any legal
process or other communication purporting to require or request her to produce testimony,
documents, information or things in any manner related to
Tekelec, its directors, officers or employees, and that she will not produce testimony,
documents, information or other things with regard to any pending or threatened lawsuit or
proceeding regarding Tekelec without giving Tekelec prior written notice of the same and reasonable
time to protect its interests with respect thereto. Former Employee further promises that when so
directed by the CEO or the Board of Directors, she will make herself available to attend any such
legal proceeding and will truthfully respond to any questions in any manner concerning or relating
to Tekelec and will produce all documents and things in her possession or under her control which
in any manner concern or relate to Tekelec. Former Employee covenants and agrees that she will
immediately notify Tekelec’s CEO in writing in the event that she breaches any of the provisions of
Sections 7, 8, 10 or 11 hereof.

12. SOLE ENTITLEMENT

     Former Employee acknowledges and agrees that her sole entitlement to compensation, payments of
any kind, monetary and nonmonetary benefits and perquisites with respect to her prior Tekelec
relationship (as an officer and employee) is as set forth in this Agreement, Tekelec’s bonus plan
for officers as in effect from time to time, stock option and warrant agreements, COBRA, Tekelec
Indemnification Agreement dated April 8, 2005 by and between Tekelec and Former Employee, and such
other written agreements and securities between Tekelec and Former Employee as may exist or as may
be set forth on Exhibit B hereto.

13. RELEASE OF CLAIMS

     13.1 General. Former Employee does hereby and forever release and discharge Tekelec
and the predecessor corporation of Tekelec as well as the successors, current, prior or future
shareholders of record, officers, directors, heirs, predecessors, assigns, agents, employees,
attorneys, insurers and representatives of each of them, past, present or future, from any and all
cause or causes of action, actions, judgments, liens, indebtedness, damages, losses, claims,
liabilities and demands of any kind or character whatsoever, whether known or unknown, suspected to
exist or not suspected to exist, anticipated or not anticipated, whether or not heretofore brought
before any state or federal agency, court or other governmental entity which are existing on or
arising prior to the date of this Agreement and which, directly or indirectly, in whole or in part,
relate or are attributable to, connected with, or incidental to the previous employment of Former
Employee by Tekelec, the separation of that employment, and any dealings between the parties
concerning Former Employee’s employment existing prior to the date of execution of this Agreement,
excepting only those obligations expressly recited herein or to be performed hereunder. Nothing
contained in this Section 12 shall affect any rights, claims or causes of action which Former
Employee may have (1) with respect to her outstanding stock options, warrants or other stock
subscription rights to purchase Tekelec Common Stock or other securities under the terms and
conditions thereof; (2) as a shareholder of Tekelec; (3) to indemnification by Tekelec, to the
extent required under the provisions of Tekelec’s Articles of Incorporation, Tekelec’s Bylaws, the
California General Corporation Law, insurance or contracts, with respect to matters relating to
Former Employee’s prior service as a director, an officer,

9

 

employee and agent of Tekelec; (4) with
respect to any other written agreement listed on Exhibit B hereto; and (5) to make claims against
or seek indemnification or contribution from anyone not released by the first sentence of this
Section 12 with respect to any matter or anyone released by
the first sentence of this Section 12 with respect to any matter not released thereby; or (6)
with respect to Tekelec’s performance of this Agreement. Further, Former Employee waives
specifically any and all rights or claims Former Employee has or may have under the ADEA and/or the
OWBPA, and acknowledges that such waiver is given voluntarily in exchange for certain consideration
included in the severance benefits being paid pursuant to this Agreement.

     13.2 Waiver of Unknown Claims. Former Employee acknowledges that she is aware that
she may hereafter discover claims or facts different from or in addition to those she now knows or
believes to be true with respect to the matters herein released, and she agrees that this release
shall be and remain in effect in all respects a complete general release as to the matters released
and all claims relative thereto which may exist or may heretofore have existed, notwithstanding any
such different or additional facts. Former Employee acknowledges that she has been informed of
Section 1542 of the Civil Code of the State of California, and does hereby expressly waive and
relinquish all rights and benefits which she has or may have under said Section or any other
comparable section under the laws of North Carolina or other state as applicable. Section 1542
reads as follows:

“A general release does not extend to claims which the creditor does
not know or suspect to exist in his favor at the time of executing
the release, which if known by her must have materially affected his
settlement with the debtor.”

     13.3 Covenant Not to Sue on Matters Released. Former Employee covenants that she will
not make, assert or maintain against any person or entity that Former Employee has released in this
Agreement, any claim, demand, action, cause of action, suit or proceeding arising out of or in
connection with the matters herein released, including but not limited to any claim or right under
the ADEA, the OWBPA, or any other federal or state statute or regulation. Former Employee
represents and warrants that she has not assigned or transferred, purported to assign or transfer,
and will not assign or transfer, any matter or claim herein released. Former Employee represents
and warrants that she knows of no other person or entity which claims an interest in the matters or
claims herein released. Former Employee agrees to, and shall at all times, indemnify and hold
harmless each person and entity that Former Employee has released in this Agreement against any
claim, demand, damage, debt, liability, account, action or cause of action, or cost or expense,
including attorneys’ fees, resulting or arising from any breach of the representations, warranties
and covenants made herein.

14. ASSIGNMENT

     Former Employee represents and warrants that she has not heretofore assigned, transferred or
granted or purported to assign, transfer or grant any claims, entitlement, matters, demands or
causes of action herein released, disclaimed, discharged or terminated, and agrees to indemnify and
hold harmless Tekelec from and against any and all costs, expense, loss or liability incurred by
Tekelec as a consequence of any such assignment, transfer or grant.

10

 

15. FORMER EMPLOYEE REPRESENTATIONS

     Except as indicated on Exhibit C, from the period beginning on May 10, 2006 through the
Effective Date , Former Employee represents and warrants that she has not acted or omitted to act
in any respect which directly or indirectly would have constituted a violation of Sections 7, 8, 10
or 11 herein had this Agreement then been in effect.

hereto shall be in writing, shall specifically reference this Agreement and shall be deemed to be
duly sent and given upon actual delivery to and receipt by the relevant party (which notice, in the
case of Tekelec, must be from an officer of Tekelec) or five days after deposit in the U.S. mail by
certified or registered mail, return receipt requested, with postage prepaid, addressed as follows

     16.2 Legal Advice and Construction of Agreement. Both Tekelec and Former Employee
have received (or have voluntarily and knowingly elected not to receive) independent legal advice
with respect to the advisability of entering into this Agreement and with respect to all matters
covered by this Agreement and neither has been entitled to rely upon or has in fact relied upon the
legal or other advice of the other party or such other party’s counsel (or employees) in entering
into this Agreement. Without limiting the generality of the foregoing, Former Employee
acknowledges that she has been encouraged to obtain independent advice concerning the tax
consequences of the severance benefits payable under this Agreement including Section 409A of the
Internal Revenue Code, and that while both parties have cooperated in an effort to minimize any
adverse tax consequences, Tekelec has not made any

11

 

representations (other than as set forth
in Section 2.3 above) regarding, nor indemnified Former Employee with respect to any tax
liabilities that may be imposed on her.

     16.3 Parties’ Understanding. Tekelec and Former Employee state that each has
carefully read this Agreement, that it has been fully explained to it/her by its/her attorney (or
that it/she has voluntarily and knowingly elected not to receive such explanation), that it/she
fully understands its final and binding effect, that the only promises made to it/her to sign the
Agreement are those stated herein, and that it/she is signing this Agreement voluntarily.

     16.4 Recitals and Section Headings. Each term of this Agreement is contractual and
not merely a recital. All recitals are incorporated by reference into this Agreement. Captions
and section headings are used herein for convenience only, are not part of this Agreement and shall
not be used in interpreting or construing it.

     16.5 Entire Agreement. This Agreement constitutes a single integrated contract
expressing the entire agreement of the parties with respect to the subject matter hereof and
supersedes all prior and contemporaneous oral and written agreements and discussions with respect
to the subject matter hereof. Notwithstanding the foregoing, the parties understand and agree that
any Nondisclosure Agreement and all other written agreements between Former Employee and Tekelec
are separate from this Agreement and, subject to the terms and conditions of each such agreement,
shall survive the execution of this Agreement, and nothing contained in this Agreement shall be
construed as affecting the rights or obligations of either party set forth in such agreements.

     16.6 Severability. In the event any provision of this Agreement or the application
thereof to any circumstance shall be determined by arbitration pursuant to Section 16.10 of this
Agreement or held by a court of competent jurisdiction to be invalid, illegal or unenforceable, or
to be excessively broad as to time, duration, geographical scope, activity, subject or otherwise,
it shall be construed to be limited or reduced so as to be enforceable to the maximum extent
allowed by applicable law as it shall then be in force, and if such construction shall not be
feasible, then such provision shall be deemed to be deleted herefrom in any action before that
court, and all other provisions of this Agreement shall remain in full force and effect.

     16.7 Amendment and Waiver. This Agreement and each provision hereof may be amended,
modified, supplemented or waived only by a written document specifically identifying this Agreement
and signed by each party hereto. Except as expressly provided in this Agreement, no course of
dealing between the parties hereto and no delay in exercising any right, power or remedy conferred
hereby or now or hereafter existing at law, in equity, by statute or otherwise, shall operate as a
waiver of, or otherwise prejudice, any such rights, power or remedy.

     16.8 Cumulative Remedies. None of the rights, powers or remedies conferred herein
shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in
addition to every other right, power or remedy, whether conferred herein or now or hereafter
available at law, in equity, by statute or otherwise.

12

 

     16.9 Specific Performance. Each party hereto may obtain specific performance to
enforce its/her rights hereunder and each party acknowledges that failure to fulfill its/her
obligations to the other party hereto would result in irreparable harm.

     16.10 Arbitration. Except for the right of either party to apply to a court of
competent jurisdiction for a Temporary Restraining Order to preserve the status quo or prevent
irreparable harm, any dispute or controversy between Tekelec and Former Employee under this
Agreement involving its interpretation or the obligations of a party hereto shall be determined by
binding arbitration in accordance with the National Rules for the Arbitration of Employment
Disputes of the American Arbitration Association, in Wake County , State of North Carolina.
Tekelec shall be responsible for paying the filing fee and tribunal costs associated with
arbitration. The arbitrators shall have the authority to permit discovery, to the extent deemed
appropriate by the arbitrator, upon request of a party. The arbitrator shall have no power or
authority to add to or, except as otherwise provided by Section 16.6 hereof, to detract from the
agreements of the parties, and the prevailing party shall recover costs and attorneys’ fees
incurred in arbitration. Employee shall not be entitled to receive any reimbursement of costs and
attorneys’ fees pursuant to this section if the parties agree that the reimbursement would be
included in the Former Employee’s income pursuant to Section 409A(a)(1)(A) of the Code, or would
result in the imposition of any additional tax or interest charge pursuant to Section 409A(a)(1)(B)
of the Code).The arbitrator shall have the authority to grant injunctive relief in a form
substantially similar to that which would otherwise be granted by a court of law. The arbitrator
shall have no authority to award punitive or consequential damages. The resulting arbitration
award may be enforced, or injunctive relief may be sought, in any court of competent jurisdiction.
Any action arising out of or relating to this Agreement may be filed only in the Superior Court of
the County of Wake, North Carolina or the United States District Court for the Eastern District of
North Carolina.

     16.11 Choice of Law and Venue. This Agreement was negotiated, executed and delivered
within the State of North Carolina, and the rights and obligations of the parties hereto shall be
construed and enforced in accordance with and governed by the internal (and not the conflict of
laws) laws of the State of North Carolina applicable to the construction and enforcement of
contracts between parties resident in North Carolina which are entered into and fully performed in
North Carolina. Any action or proceeding arising out of, relating to or concerning this Agreement
that is not subject to the arbitration provisions set forth in Section 16.10 above shall be filed
in the state courts of the County of Wake, State of North Carolina or in a United States District
Court for the Eastern District of North Carolina and in no other location. The parties hereby
waive the right to object to such location on the basis of venue.

     16.12 Attorneys’ Fees. In the event a lawsuit is instituted by either party
concerning a dispute under this Agreement, the prevailing party in such lawsuit shall be entitled
to recover from the losing party all reasonable attorneys’ fees, costs of suit and expenses
(including the reasonable fees, costs and expenses of appeals), in addition to whatever damages or
other relief the injured party is otherwise entitled to under law or equity in connection with such
dispute; provided, however, that Former Employee shall not be entitled to receive any reimbursement
of costs, expenses and attorneys’ fees pursuant to this section if the parties agree that the

13

 

reimbursement
would be included in the Former Employee’s income pursuant to Section 409A(a)(1)(A) of the
Code, or would result in the imposition of any additional tax or interest charge pursuant to
Section 409A(a)(1)(B) of the Code.

     16.13 Force Majeure. Neither Tekelec nor Former Employee shall be deemed in default
if its/her performance of obligations hereunder is delayed or become impossible or impracticable by
reason of any act of God, war, fire, earthquake, strike, civil commotion, epidemic, or any other
cause beyond such party’s reasonable control.

     16.14 Counterparts. This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute one and the same
instrument.

     16.15 Successors and Assigns. Neither party may assign this Agreement or any of its
rights or obligations hereunder (including, without limitation, rights and duties of performance)
to any third party or entity, and this Agreement may not be involuntarily assigned or assigned by
operation of law, without the prior written consent of the non-assigning party, which consent may
be given or withheld by such non-assigning party in the sole exercise of its discretion, except
that Tekelec may assign this Agreement to a corporation acquiring: (1) 50% or more of Tekelec’s
capital stock in a merger or acquisition; or (2) all or substantially all of the assets of Tekelec
in a single transaction; and except that Former Employee may transfer or assign her rights under
this Agreement voluntarily, involuntarily or by operation of law upon or as a result of her death
to her heirs, estate and/or personal representative(s). Any prohibited assignment shall be null
and void, and any attempted assignment of this Agreement in violation of this section shall
constitute a material breach of this Agreement and cause for its termination by and at the election
of the other party hereto by notice. This Agreement shall be binding upon and inure to the benefit
of each of the parties hereto and each person or entity released pursuant to Section 12 hereof and,
except as otherwise provided herein, their respective legal successors and permitted assigns.

     16.16 Payment Procedure. Except as otherwise explicitly provided herein or in the
Severance Plan, all payments by Tekelec to Former Employee or by Former Employee to Tekelec due
hereunder may be by, at the paying party’s election, cash, wire transfer or check. Except as
explicitly provided herein or in the Severance Plan, neither party may reduce any payment or
obligation due hereunder by any amount owed or believed owed to the other party under any other
agreement, whether oral or written, now in effect or hereafter entered into.

obligations set forth in Sections 7, 8 and 10 through 16 shall survive any termination of this
Agreement for any reason whatsoever.

     16.18 No Admission. Neither the entry into this Agreement nor the giving of
consideration hereunder shall constitute an admission of any wrongdoing by Tekelec or Former
Employee.

     16.19 Limitation of Damages. Except as expressly set forth herein, in any action or
proceeding arising out of, relating to or concerning this Agreement, including any claim of

14

 

breach
of contract, liability shall be limited to compensatory damages proximately caused by the
breach and neither party shall, under any circumstances, be liable to the other party for
consequential, incidental, indirect or special damages, including but not limited to lost profits
or income, even if such party has been apprised of the likelihood of such damages occurring.

     16.20 Pronouns. As used herein, the words “she”, “her” and “herself” shall be deemed
to refer to the feminine as the identity of the person referred to and the context may require.

     16.21 Effectiveness. This Agreement shall become effective upon execution by the
later of the parties hereto to execute this Agreement.

17. 21 DAY REVIEW PERIOD; RIGHT TO REVOKE

acknowledges that she has been given a period of 21 days within which to consider the terms and
provisions of this Agreement with her attorney. If Former Employee has executed and delivered to
Tekelec this Agreement prior to the expiration of such 21-day period, then in doing so, Former
Employee acknowledges that she has unconditionally and irrevocably waived her right to that
unexpired portion of such 21-day period. In addition, Former Employee shall have the right to
revoke this Agreement for a period of seven days following the date on which this Agreement is

18. 409A COMPLIANCE

     18.1 Severance Plan Superseded. The parties intend that this Agreement shall
constitute an amendment and restatement of the Severance Plan’s provisions as they apply to Former
Employee for the purpose of bringing the Severance Plan documentation into compliance with Code
Section 409A, effective retroactively to January 1, 2005.

     18.2 Construction in Accordance with Code Section 409A. The parties agree that,
pending the effective date of final regulations, this Agreement shall be administered in good faith
in compliance with Section 409A of the Code, and applicable guidance thereunder, with respect to
any amounts treated as compensation deferred after December 31, 2004. The parties intend that the
terms of this Agreement be construed in a manner consistent with Code Section 409A and in a manner
that will not result in amounts being included in the Former Employee’s income pursuant to Section
409A(a)(1)(A) of the Code, or that would result in the imposition of any additional tax or interest
charge pursuant to Section 409A(a)(1)(B) of the Code.

     18.3 Tekelec and Former Employee agree to cooperate to the extent reasonably necessary
(without unreasonable cost or burden to Tekelec) to prevent amounts payable hereunder from being
included in Former Employee’s income pursuant to Section 409A(1)(A) of the Code or being subject to
any additional tax or interest charge pursuant to Section 409A(a)(1)(B) of the Code, provided that
there shall be no change in the value of Former

15

 

Employee’s compensation or benefits or in Tekelec’s costs or administrative burdens in fulfilling
its obligations under the applicable plan, agreement or arrangement.

AMENDED AND RESTATED

TEKELEC 2005 EMPLOYEE STOCK PURCHASE PLAN

     The following constitutes the provisions of the Amended and Restated Tekelec 2005 Employee
Stock Purchase Plan (the “Plan”).

     1. Purpose. The purpose of the Plan is to provide employees of Tekelec (the
“Company”) and its subsidiaries with an opportunity to purchase Common Stock of the Company through
payroll deductions. It is the intention of the Company that the Plan qualify as an “Employee Stock
Purchase Plan” under Section 423 of the Internal Revenue Code of 1986, as amended. The provisions
of the Plan shall, accordingly, be construed so as to extend and limit participation in a manner
consistent with the requirements of that section of the Code, as amended from time to time. The
Plan modifies, supplements and supersedes the terms of the Original Plan (as defined herein), as
modified, supplemented and superseded by the Supplemental Provisions approved by the Compensation
Committee of the Company’s Board of Directors on June 10, 2005.

     2. Certain Definitions.

          (a) “Amendment Effective Date” shall mean June 26, 2006.

          (b) “Board” shall mean the Board of Directors of the Company or any committee thereof
designated by the Board of Directors of the Company in accordance with Section 13 of the Plan.

          (c) “Code” shall mean the Internal Revenue Code of 1986, as amended, and any applicable
regulations promulgated thereunder.

          (d) “Common Stock” shall mean the common stock of the Company.

          (e) “Compensation,” unless otherwise determined by the Board of Directors of the Company,

options or participation in a stock option or purchase programs and contributions by the Company to
qualified deferred compensation plans.

          (f) “Eligible Subsidiary” means any subsidiary that from time to time is expressly designated
by the Board as being an “Eligible Subsidiary” for purposes of the Plan. As of the Amendment
Effective Date, each of Santera Systems Inc., VocalData, Inc. and Taqua, Inc. has been designated

of any other Subsidiary are not eligible to participate in the Plan.

          (g) “Employee” means any person, including an officer, who is customarily employed for more
than 20 hours per week by the Company or its Eligible Subsidiary and more

 

 

than five months in any
calendar year. For purposes of the Plan, the employment relationship shall be treated as
continuing intact while the individual is on sick leave or other leave of absence approved by the
Company. Where the period of leave exceeds 90 days and the individual’s right to reemployment is
not guaranteed either by statute or by contract, the employment relationship shall be deemed to
have terminated on the 91st day of such leave.

SmallCap Market of The Nasdaq Stock Market, its fair market value shall be the closing sales
price for such stock (or the mean of the closing bid and asked prices, if no sales were
reported) as reported on such date (or, if such day is not a Trading Day, on the most recent
Trading Day prior to such date) in The Wall Street Journal or such other source as
the Board deems reliable;

               (ii) If the Common Stock is regularly quoted by a recognized securities dealer but
sales prices are not reported, its fair market value shall be the mean of the closing bid
and asked prices for the Common Stock on such date (or, if such day is not a Trading Day, on
the most recent Trading Day prior to such date), as reported in The Wall Street
Journal or such other source as the Board deems reliable; or

               (iii) In the absence of an established market for the Common Stock, the fair market
value thereof shall be determined in good faith by the Board.

2

 

          (n) “Purchase Price” shall mean 85% of the Fair Market Value of a share of Common Stock on the
Enrollment Date or on the Exercise Date, whichever is lower; provided, however,
that the Purchase Price may be adjusted by the Board pursuant to Section 19.

          (o) “Subsidiary” means any corporation described in Section 424 of the Code in which the
Company owns, directly or indirectly, 50% or more of the voting shares.

          (p) “Trading Day” shall mean a day on which national stock exchanges and The Nasdaq Stock
Market are open for trading.

     3. Eligibility.

          (b) Exceptions. Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan if:

               (i) immediately after the grant, such Employee (or any other person whose stock
ownership would be attributed to such Employee pursuant to Section 424(d) of the Code) would
own shares and/or hold outstanding options to purchase shares possessing five percent or
more of the total combined voting power or value of all classes of shares of the Company or
of any Subsidiary; or

                (ii) such option would permit the Employee’s rights to purchase shares under all
employee stock purchase plans of the Company and its Subsidiaries to accrue (i.e., become
exercisable) at a rate which exceeds $25,000 of fair market value of such shares (determined
at the time such option is granted) for any calendar year in which such option is
outstanding at any time.

     4. Offering Periods.

          (a) Prior to the Amendment Effective Date. Prior to the Amendment Effective Date and
subject to Section 4(c) below, the Plan shall be implemented by consecutive, overlapping 24-month
Offering Periods with a new 24-month Offering Period commencing on the first Trading Day on or
after August 1 and February 1 of each year, or on such other date as the Board shall determine, and
continuing thereafter until terminated in accordance with Section 20 hereof. The first such
24-month Offering Period under the Plan shall commence on August 1, 2005.

          (b) Subsequent to the Amendment Effective Date. Subsequent to the Amendment Effective
Date, the Plan shall be implemented by consecutive six-month Offering Periods. The first such
six-month Offering Period shall commence on August 1, 2006.

          (c) Offering Period Commencing on February 1, 2006. Notwithstanding the terms of the
Original Plan and Section 4(a) above, the Offering Period that commenced on February 1, 2006 shall
terminate on July 31, 2006.

          (d) Change of Duration of Offering Periods. The Board shall have the power to change
the duration of Offering Periods (including the commencement dates thereof) with respect to future
offerings without shareholder approval if any such change is announced at least five days prior to
the scheduled beginning of the first Offering Period to be affected thereafter.

          (e) Effect of Participation in an Offering Period. Participation in one offering
under the Plan shall neither limit nor require participation in any other offering.

     5. Participation.

          (a) Enrollment. An eligible Employee may become a participant in the Plan by
completing and signing a subscription agreement authorizing payroll deductions in the form of the
Subscription Agreement attached to this Plan as Attachment A (the “Subscription Agreement”)
and by filing it with the Company’s payroll office on or before the 25th day of the calendar month
prior to the start of the applicable Offering Period with respect to which it is to be effective
(unless a different time for filing the Subscription
Agreement has been set by the Company with respect to a given offering). The Company will
provide employees with advance notice of all such enrollment periods. Enrollment periods will
typically commence on or about the first day of the calendar month immediately prior to the
commencement of an Offering Period and will end on such 25th day of such calendar month. An
Employee’s authorization and participation in the Plan shall become effective on the first
Enrollment Date following the timely filing of his or her Subscription Agreement and shall remain
effective until revoked by the participant by the filing of a Payroll Deduction Authorization
Change or Withdrawal form as described in Section 10(a) hereof or until changed by the filing of a
Payroll Deduction Authorization Change or Withdrawal form providing for a change in the
participant’s payroll deduction rate. An Employee who becomes eligible to participate in the Plan
after the commencement of an Offering Period or who is eligible but declines to participate prior
to the commencement of such Offering Period may not become a participant in the Plan until the
commencement of the next Offering Period.

     6. Payroll Deductions.

          (a) Commencement of Deductions. Payroll deductions for a participant shall commence
on the first payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period as to which such authorization is applicable, unless sooner terminated by the
participant as provided in Section 10 hereof.

          (b) Rate of Deductions. At the time a participant files his or her Subscription
Agreement with the Company, he or she shall elect to have payroll deductions made on each payday
during the next Offering Period at a percentage rate equal to a positive whole number not exceeding
15%, or such other maximum rate as may be determined from time to time by the Board subject to the
provisions of Section 19 hereof, of the Compensation which would otherwise be payable to such
participant on each such payday.

4

 

          (c) Automatic Continuation of Deductions. Payroll deductions for a participant shall
automatically continue from Offering Period to Offering Period until changed or terminated by the
participant in accordance with the terms hereof.

          (d) Credit to Plan Accounts. All payroll deductions authorized by a participant shall
be credited to the participant’s individual account under the Plan. A participant may not make any
additional payments into such account.

          (e) Termination of Deductions and Changes in Rate of Payroll Deductions. A
participant may terminate his or her participation in the Plan prior to the termination of any
Purchase Period as provided in Section 10 hereof, or may increase or decrease the rate of his or
her payroll deductions for a future Purchase Period by completing and filing with the Company, on
or before the 25th day of the calendar month prior to the start of the next Purchase Period, a
Payroll Deduction Authorization Change or Withdrawal form in the form attached hereto as
Attachment B (“Payroll Deduction Authorization Change or Withdrawal Form”) authorizing a
change in payroll deduction rate or a withdrawal, as applicable; provided, however,
that prior to the Amendment Effective Date, any such increase in the rate of payroll deductions
with respect to a future six-month Purchase Period (as opposed to a future 24-month Offering
Period) was limited to a maximum increase of 5%. The Board may, in its discretion, limit the
number of participation rate changes during any Offering Period. The change in rate shall be
effective as of the first full payday of the next Purchase Period. A participant’s Subscription
Agreement shall remain in effect for successive Offering Periods (and, prior to the Amendment
Effective Date, for successive Purchase Periods within a 24-Month Offering Period) unless
terminated as provided in Section 10 hereof.

     7. Grant of Option. On the Enrollment Date of each Offering Period, each participant
in such Offering Period shall automatically be granted an option to purchase on the Exercise Date
during such Offering Period (or, prior to the Amendment Effective Date, on each Exercise Date
during such Offering Period), at the applicable Purchase Price, up to a number of shares of the
Company’s Common Stock determined by dividing such Employee’s payroll deductions accumulated prior
to such Exercise Date and retained in the participant’s account as of the Exercise Date by the
applicable Purchase Price; provided, however, that in no event shall an Employee be
permitted to purchase during each Purchase Period more than a number of shares equal to the lesser
of (1) the number of Shares determined by dividing $12,500 by the Fair Market Value of a share of
the Company’s Common Stock (subject to any adjustment pursuant to Section 19) on the Enrollment
Date or (2) 1,500 shares, and provided further that such grant of options and purchase shall in all
cases be subject to the limitations set forth in Sections 3(b) and 12 hereof. The Board may, for
future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of
shares of the Company’s Common Stock an Employee may purchase during each Purchase Period.
Exercise of the option shall occur as provided in Section 8 hereof, unless the participant has
withdrawn pursuant to Section 10 hereof. The option shall expire on the last day of the Offering
Period.

5

 

     8. Exercise of Option.

          (a) Automatic Exercise on Exercise Dates. Unless a participant withdraws from the
Plan as provided in Section 10, his or her option for the purchase of shares shall be exercised
automatically on each Exercise Date and the accumulated payroll deductions credited to a
participant’s account on the Exercise Date will be applied to purchase whole shares of the
Company’s Common Stock (up to the maximum number subject to option as determined in Section 7
hereof) at the Purchase Price. Any amount credited to a participant’s account and not applied to
the purchase of Common Stock by reason of the limitation on the number of shares subject to option
(including amounts representing a fractional share) shall be
refunded promptly to such participant after the Exercise Date. A participant’s option to
purchase shares hereunder shall be nontransferable other than by will or the laws of descent and
distribution and shall be exercisable during the participant’s lifetime only by the participant.

          (b) Allocation of Shares if Insufficient Shares are Available on Enrollment or Exercise
Date. If the Board determines that, on a given Enrollment Date or Exercise Date, the number of
shares with respect to which options are to be granted or exercised, as applicable, may exceed (i)
the number of shares of Common Stock that were available for sale under the Plan on the Enrollment
Date of the applicable Offering Period, or (ii) the number of shares available for sale under the
Plan on such Exercise Date, the Board may in its sole discretion (x) provide that the Company shall
make a pro rata allocation of the shares of Common Stock available for grant or purchase on such
Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable and
as it shall determine in its sole discretion to be equitable among all participants granted options
to purchase Common Stock on such Enrollment Date or exercising options to purchase Common Stock on
such Exercise Date, as applicable, and continue the Offering Period(s) then in effect, or (y)
provide that the Company shall make a pro rata allocation of the shares available for grant or
purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable among all
participants granted options to purchase Common Stock on such Enrollment Date or exercising options
to purchase Common Stock on such Exercise Date, and terminate any Offering Period(s) then in effect
pursuant to Section 19 hereof. The Company may make a pro rata allocation of the shares available
on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence,
notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s
shareholders subsequent to such Enrollment Date. In the event of any pro rata allocation of
shares, the Company shall give written notice of such allocation to each participant affected
thereby and shall reduce the rate of payroll deductions, if necessary.

     9. Delivery; Holding Period. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange for the issuance and delivery to, or
credit to the account of, each participant, as appropriate, of the shares purchased upon exercise
of his or her option. At the election of the Company, the issuance and delivery of the shares
purchased upon exercise of a participant’s option may be effected by transfer (electronic or
otherwise in the discretion of the Company) of such shares to a securities account maintained in
the participant’s name. The shares purchased upon exercise of any option granted to a participant
may not be assigned, transferred, pledged or otherwise disposed of in any way (other than by will
or by the laws

6

 

of descent and distribution) for a period of (i) 90 days following the exercise of
any option on or prior to the Amendment Effective Date or (ii) 30 days following the exercise of
any option subsequent to the Amendment Effective Date; provided, however, that the
Board of Directors may, in its sole discretion, permit an assignment, transfer, pledge
or other disposition of such shares at such other time as the Company’s Board of Directors may
determine in the event that the participant has suffered a hardship, as determined by the Company’s
Board of Directors in its sole discretion. Shares purchased upon exercise of any option granted to
a participant and subject to the above restrictions may include a legend indicating that such
shares may not be transferred, pledged or otherwise disposed of for 90 days or 30 days, as
applicable, from the date of issue.

     10. Withdrawal; Termination of Employment.

          (a) Withdrawal from Plan and Immediate Cancellation of Option. A participant may
terminate his or her participation in an offering under the Plan and withdraw all, but not less
than all, of the payroll deductions credited to his or her account under the Plan at any time prior
to an Exercise Date by giving written notice of withdrawal to the Company on a Payroll Deduction
Authorization Change or Withdrawal Form. In such case, all of the participant’s payroll deductions
credited to his or her account shall be paid to him or her promptly after receipt of his or her
notice of withdrawal, his or her option for the Offering Period shall be automatically canceled,
and no further payroll deductions for the purchase of shares shall be made for such Offering
Period. If a participant withdraws from an Offering Period, payroll deductions shall not resume at
the beginning of the succeeding Offering Period unless the participant delivers to the Company a
new Subscription Agreement in accordance with Section 5 hereof.

          (b) Withdrawal from Plan without Cancellation of Option in Current Purchase Period. A
participant may terminate his or her participation in the Plan effective as of the first day of the
next Purchase Period by giving written notice of withdrawal to the Company on a Payroll Deduction
Authorization Change or Withdrawal Form. In such case, the participant’s payroll deductions will
continue through the end of the Purchase Period in which the notice of withdrawal is given, all
amounts deducted from the participant’s Compensation during such Purchase Period will be applied to
the purchase of Common Stock pursuant to the Plan, and following such termination of participation
no further payroll deductions for the purchase of shares shall be made except pursuant to a new
Subscription Agreement delivered in accordance with Section 5 hereof.

          (c) Termination of Employment. Upon termination of a participant’s employment for any
reason, including retirement or death, as soon as practicable after such termination, the payroll
deductions credited to his or her account shall be returned to him or her or, in the case of his or
her death, to the person or persons entitled thereto under Section 14, and his or her option shall
be automatically canceled.

          (d) Employment for Less than 20 Hours Per Week. In the event an Employee fails to
remain in the continuous employ of the Company or its Eligible Subsidiaries for more than 20 hours
per week during the Offering Period in which the
Employee is a participant, he or she will be deemed to have elected to withdraw from the Plan
and the payroll deductions credited to his or her account will be returned to him or her and his or
her option will be canceled.

7

 

          (e) Effect of Withdrawal on Future Eligibility. A participant’s withdrawal from an
offering shall not have any effect upon his or her eligibility to participate in a subsequent
offering or in any similar plan which may hereafter be adopted by the Company.

     11. Interest. No interest shall accrue on the payroll deductions of a participant in
the Plan.

     12. Stock.

          (a) Authorized Shares. The maximum number of shares of the Company’s Common Stock
which shall be made available for sale under the Plan shall be 1,000,000 shares, subject to
adjustment upon changes in capitalization of the Company as provided in Section 18(a) hereof,
together with a cumulative annual increase to the number of shares reserved for issuance thereunder
on August 1, 2006 and on each August 1 thereafter equal to the lesser of (i) 500,000 shares, (ii)
1% of the number of outstanding shares of Common Stock of the Company on the date of such increase
or (iii) such amount as may be determined by the Board. The shares to be sold to participants in
the Plan will be authorized but unissued shares. Upon the cancellation of any option granted under
the Plan, the shares subject thereto shall return to the Plan and become available for options
thereafter granted under the Plan.

          (b) No Interest or Voting Rights in Shares. A participant will have no interest or
voting right in shares covered by his or her option until such option has been exercised.

          (c) Registration of Shares. Shares to be issued to a participant under the Plan
shall, as specified in the participant’s Subscription Agreement, be registered in the name of the
participant or in the name of the participant and his or her spouse.

     13. Administration. The Plan shall be administered by the Board or a committee of
members of the Board appointed by the Board. The Board or its committee shall have full and
exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to
determine eligibility and to adjudicate all disputed claims filed under the Plan. Every finding,
decision and determination made by the Board or its committee shall, to the fullest extent
permitted by law, be final and binding upon all parties.

     14. Designation of Beneficiary.

          (a) Designation. A participant may file a written designation of a beneficiary who is
to receive any shares and cash, if any, from the participant’s account under the Plan in the event
of such participant’s death subsequent to the Exercise Date on which an option is exercised but
prior to delivery to him or her of such shares and cash. In addition, a participant may file a
written designation of a beneficiary who is to receive any cash from the participant’s account
under the Plan in the event of such participant’s death prior to exercise of the option. If a
participant is married and the designated beneficiary is not the spouse, spousal consent shall be
required for such designation to be effective.

8

 

          (b) Change in Beneficiary. Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a participant and in the
absence of a valid designation of a beneficiary who is living at the time of such participant’s
death, the Company shall deliver such shares and/or cash to the executor or administrator of the
estate of the participant; or if no such executor or administrator has been appointed (to the
knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to
the spouse or to any one or more dependents or relatives of the participant; or if no spouse,
dependent or relative is known to the Company, then to such other person as the Company may
designate.

     15. Transferability. Neither payroll deductions credited to a participant’s account
nor any rights with regard to the exercise of an option or to receive shares under the Plan may be
assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of
descent and distribution, pursuant to a qualified domestic relations order as defined by the Code
or Title I of the Employee Retirement Income Security Act, or the rules thereunder, or as provided
in Section 14 hereof) by the participant. Any such attempt at assignment, transfer, pledge or
other disposition shall be without effect, except that the Company may treat such act as an
election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

     16. Use of Funds. All payroll deductions received or held by the Company on behalf of
a participant under the Plan may be used by the Company for any corporate purpose, and the Company
shall not be obligated to segregate such payroll deductions.

     17. Reports. Individual accounts will be maintained for each participant in the Plan. Individual
statements of account will be given to participating Employees at least annually, which statements
shall set forth the amounts of payroll deductions, the Purchase Price, the number of shares
purchased and the remaining cash balance, if any, in a participant’s account.

     18. Adjustments upon Changes in Capitalization or Control.

          (a) Changes in Capitalization. Subject to any required action by the shareholders of
the Company, the number of shares of Common Stock covered by each option under the Plan which has
not yet been exercised and the number of shares of Common Stock which has been authorized for
issuance under the Plan but has not yet been placed under option or which has been returned to the
Plan upon the cancellation of an option, as well as the option price per share of Common Stock
covered by each option under the Plan which has not yet been exercised, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from
a stock split, reverse stock split, stock dividend, combination of the Common Stock, or any other
increase or decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any convertible
securities of the Company shall not be deemed to have been “effected without receipt of
consideration.” Such adjustment shall be made by the Board, whose determination in that respect
shall be final, binding and conclusive. Except as expressly provided herein, no issue by the
Company of shares of stock of any class, or securities convertible into shares of stock of any
class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number
or price of shares of Common Stock subject to option.

9

 

          (b) Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Offering Period then in progress shall be shortened by setting a
new Exercise Date (the “New Exercise Date”), and shall terminate immediately prior to the
consummation of such proposed dissolution or liquidation, unless provided otherwise by the Board.
The New Exercise Date shall be before the date of the Company’s proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten business days prior
to the New Exercise Date, that the Exercise Date for the participant’s option has been changed to
the New Exercise Date and that the participant’s option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as
provided in Section 10 hereof.

          (c) Merger or Asset Sale. In the event of a proposed sale of all or substantially all
of the assets of the Company, or the merger of the Company with or into another corporation, each
outstanding option shall be assumed or an equivalent option substituted by the successor
corporation or a parent or subsidiary of the successor corporation. In the event that the
successor corporation refuses to assume or substitute for the option, any Purchase Periods then in
progress shall be shortened by setting a new Exercise
Date (the “Modified Exercise Date”) and any Offering Periods then in progress shall end on the
Modified Exercise Date. The Modified Exercise Date shall be before the date of the Company’s
proposed sale or merger. The Board shall notify each participant in writing, at least ten business
days prior to the Modified Exercise Date, that the Exercise Date for the participant’s option has
been changed to the Modified Exercise Date and that the participant’s option shall be exercised
automatically on the Modified Exercise Date, unless prior to such date the participant has
withdrawn from the Offering Period as provided in Section 10 hereof.

          (d) No Fractional Shares. No fractional shares of Common Stock shall be issuable on
account of any adjustment described herein, and the aggregate number of shares into which shares
then covered by an option, when changed as the result of such adjustment, shall be reduced to the
largest number of whole shares resulting from such adjustment, unless the Board, in its sole
discretion, shall determine to issue scrip certificates in respect to any fractional shares, which
scrip certificates, in such event, shall be in a form and have such terms and conditions as the
Board in its discretion shall prescribe.

     19. Amendment or Termination.

          (a) Amendment and Termination in General. The Board of Directors of the Company may
at any time and for any reason terminate or amend the Plan. Except as provided in Section 18
hereof, no such amendment or termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date if the Board
determines that the termination of the Offering Period or the Plan is in the best interests of the
Company and its shareholders. Except as provided in Section 18 and this Section 19, no amendment
may make any change in any option theretofore granted which adversely affects the rights of any
participant without the prior written consent of such participant.

10

 

          (b) Modifications Relating to Section 423 of the Code. To the extent necessary to
comply with Section 423 of the Code (or any successor rule or provision or any other applicable
law, regulation or stock exchange rule), the Company shall obtain shareholder approval of any
amendment to the Plan in such a manner and to such a degree as is required.

          (c) Limitations and Procedures with respect to Offering Periods. Without shareholder
approval and without regard to whether any participant rights may be considered to have been
“adversely affected,” the Board (or its committee) shall be entitled to change the Offering
Periods, limit the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S.
dollars, permit payroll withholding in excess of the amount designated by a participant in order to
adjust for delays or mistakes in the Company’s processing of properly completed withholding
elections, establish reasonable waiting and
adjustment periods and/or accounting and crediting procedures to ensure that amounts applied
toward the purchase of Common Stock for each participant properly correspond with amounts withheld
from the participant’s Compensation, and establish such other limitations or procedures as the
Board (or its committee) determines in its sole discretion advisable which are consistent with the
Plan.

          (d) Modifications Relating to Unfavorable Accounting Consequences. In the event the
Board determines that the ongoing operation of the Plan may result in unfavorable financial
accounting consequences, the Board may, in its discretion and to the extent necessary or desirable,
modify or amend the Plan to reduce or eliminate such accounting consequence including, but not
limited to:

                (i) altering the Purchase Price for any Offering Period including an Offering Period
underway at the time of the change in Purchase Price;

               (ii) shortening any Offering Period so that Offering Period ends on a new Exercise
Date, including an Offering Period underway at the time of the Board action; and

               (iii) allocating shares.

          Such modifications or amendments shall not require shareholder approval or the consent of any
Plan participants.

     20. Term of Plan. The Original Plan became effective upon its approval by vote of the
outstanding shares of the Company as provided in Section 22. The Plan shall continue in effect for
a term of ten years following the date of approval of the Original Plan by the Board (i.e., until
May 13, 2015) unless sooner terminated under Sections 19 or 22 hereof.

     21. Notices. All notices or other communications (i) by a participant to the Company
in connection with the Plan shall be deemed to have been duly given when received in the form
specified by the Company at the location, or by the person, designated by the Company for the
receipt thereof and (ii) by the Company to a participant in connection with the Plan shall be
deemed to have been duly given when received by the participant or, if earlier, five days after
deposit in the

11

 

United States mail by certified or registered mail, return receipt requested, first
class postage prepaid, addressed to the participant at his or her address as shown on the records
of the Company or as such participant may request by written notice to the Company hereunder.

     22. Shareholder Approval. The effectiveness of the Original Plan was expressly subject to approval by the Company’s
shareholders prior to August 31, 2005 by the affirmative vote of the holders of a majority of the
outstanding shares of stock of the Company present or represented and entitled to vote thereon at a
shareholder meeting duly held or by written consent in accordance with applicable law. Such
approval was given at a regular meeting of the Company’s shareholders held on May 13, 2005. The
amendment and restatement of the Original Plan as of the Amendment Effective Date is not subject to
the approval of the Company’s shareholders.

     23. Automatic Transfer to Low Price Offering Period. Prior to the Amendment Effective
Date and to the extent permitted by any applicable laws, regulations or stock exchange or market
system rules, if the Fair Market Value of the Common Stock on any Exercise Date in an Offering
Period is lower than the Fair Market Value of the Common Stock on the Enrollment Date of such
Offering Period, then all participants in the Offering Period shall be automatically withdrawn from
such Offering Period immediately after the exercise of their option on such Exercise Date and
automatically re-enrolled in the immediately following Offering Period as of the first day thereof
in accordance with the terms and conditions of their Subscription Agreement then in effect.
Effective as of the Amendment Effective Date, this Section 23 shall not apply to any Offering
Periods then in effect or commencing thereafter.

     24. No Enlargement of Employee Rights. The Plan is purely voluntary on the part of
the Company, and the continuance of the Plan shall not be deemed to constitute a contract between
the Company and any Employee, or to be consideration for or a condition of the employment of any
Employee. Nothing contained in this Plan shall be deemed to give any Employee the right to be
retained in the employ of the Company, its parent, any Subsidiary or a successor corporation, or to
interfere with the right of the Company or any such corporations to discharge or retire any
Employee thereof at any time. No Employee shall have any right to or interest in options
authorized hereunder prior to the grant of an option to such Employee, and upon such grant he or
she shall have only such rights and interests as are expressly provided herein, subject, however,
to all applicable provisions of the Company’s Articles of Incorporation, as the same may be amended
from time to time.

     25. Information to Participants. The Company shall provide without charge to each
participant in the Plan copies of such annual and periodic reports as are provided by the Company
to its shareholders generally.

     26. Governing Law. To the extent that federal laws do not otherwise control, the Plan and all determinations
made or actions taken pursuant hereto shall be governed by the laws of the State of California,
without regard to the conflicts of laws rules thereof.

     27. Tax Withholding. If at any time the Company or any Eligible Subsidiary is
required, under applicable laws and regulations, to withhold, or to make any deduction of, any
taxes or take any other action in connection with any exercise of an option granted hereunder or
any disposition

12

 

of shares of Common Stock issued hereunder, the participant must make adequate
provision for the Company’s federal, state or other tax withholding obligations which arise from
such exercise or disposition. The Company or such Eligible Subsidiary shall have the right to
deduct or withhold from the participant’s compensation the amount necessary for the Company or such
Eligible Subsidiary to meet applicable withholding obligations.

     28. Securities Law Compliance. No shares of Common Stock may be issued upon the
exercise of any option under the Plan until all requirements of applicable federal, state, foreign
or other securities laws with respect to the purchase, sale and issuance of shares of Common Stock
shall have been satisfied. If any action must be taken because of such requirements, then the
purchase, sale and issuance of shares shall be postponed until such action can reasonably be taken.
Upon request by the Company, an Employee shall deliver to the Company such information,
representations or undertakings as the Company may reasonably request in order to comply with any
registration requirements or exemptions therefrom of applicable securities laws. The Company may
require any securities so issued to bear a legend, may give its transfer agent instructions, and
may take such other steps as in its judgment are reasonably required to prevent any violation of
applicable securities laws.

Subscription Agreement and subject to the terms and conditions of the Plan.

Offering Period commencing (check one): o August 1, 200___   o February 1,
200___

	2.	 	I hereby authorize Tekelec to make regular payroll deductions, at the rate indicated below
and in accordance with the terms of the Plan, from the total Compensation (as defined in the
Plan) including overtime, bonuses, commissions and other earnings, if any, paid to me during
each Offering Period during which I remain a participant in the Plan:

	3.	 	I understand that payroll deductions at the indicated rate will continue from Offering Period
