                  2003 STOCK OPTION PLAN

Restricted Stock Unit Award Agreement



Tekelec ("Tekelec" or the "Company") hereby grants to you a Restricted Stock Unit Award
under the Tekelec Amended and Restated 2003 Stock Option Plan (the "Plan"), as set forth below. 


	
Name:
	
Franco Plastina

	
Date of Grant:
	
May 7, 2007

	
Number of Restricted Stock Units:
	
100,000

	
Nature of  Restricted Stock Units:
	
Each Restricted Stock Unit ("RSU") represents the right to receive
one share ("Share") of Tekelec Common Stock to be issued and delivered at the end of any applicable vesting period, subject to the risk of
cancellation as described in the Plan.

	
Vesting Schedule:
	
For purposes of the RSUs, the Compensation Committee of the Company's
Board of Directors has established both an operating income-based objective and a revenue-based objective for the Company's fiscal year
ending December 31, 2007 (the "2007 Fiscal Year").  These objectives are set forth in Supplemental Provisions incorporated herein by
reference.

If the Company achieves the operating income-based objective for the 2007 Fiscal Year, the RSUs will become
eligible for vesting as set forth below based on the extent to which the Company achieves the revenue-based objective for the 2007 Fiscal
Year:

	 	


	if the Company achieves less than 80% of the revenue-based objective, the
RSUs will be forfeited; 


	if the Company achieves between 80% and 89.99% of the revenue-based objective, 80,000 RSUs will vest as set
forth below; 


	if the Company achieves between 90% and 99.99% of the revenue-based objective, 90,000 RSUs will vest as set
forth below; and 


	if the Company achieves 100% or more of the revenue-based objective, all 100,000 RSUs will vest as set forth
below.





	 	
To the extent that any of the RSUs become eligible for vesting as provided
above, the RSUs will vest over a four-year period, with 25% of the RSUs vesting on May 7, 2008 and the remaining 75% of the RSUs vesting
in three equal installments on May 7, 2009, May 7, 2010 and May 7, 2011, provided that with respect to each such vesting of an installment
you remain an employee of the Company (or any of its affiliates) from the RSU grant date through such
vesting date.










	
Forfeiture:
	
If you cease to serve as an Employee for any reason, any RSUs which are not
vested as of the date of such termination shall not vest and shall automatically be cancelled and forfeited for no value and without any
issuance of Shares.

	
Taxes:
	
Payment of the applicable taxes in connection with the vesting of RSUs must be
made by check or a Cashless Exercise (see Section 4(c) of Restricted Stock Unit Terms and Conditions attached hereto).

TEKELEC AMENDED AND RESTATED

2003 STOCK OPTION PLAN 

Restricted Stock Unit Award Agreement - Restricted Stock Unit Terms and Conditions

The following Restricted Stock Unit Terms and Conditions apply to the Restricted Stock Unit Award granted by
Tekelec ("Tekelec" or the "Company") to the Participant whose name appears on the Restricted Stock Unit Award Agreement cover page to
which these Restricted Stock Unit Terms and Conditions are attached.





	Amended and Restated 2003 Stock Option Plan.  This Restricted Stock Unit Award is in all respects
subject to the terms, definitions and provisions of the Tekelec Amended and Restated 2003 Stock Option Plan (the "Plan") adopted by the
Company and incorporated herein by reference.  Capitalized terms defined in the Plan but not defined in this Restricted Stock Unit Award
Agreement shall have the meanings given to them in the Plan.


	Vesting of Restricted Stock Units Awards.



	Upon each vesting date for the Restricted Stock Unit Award (each, a "Vesting Date"), one share of Tekelec
Common Stock shall be issuable for each Restricted Stock Unit that vests on such date, subject to the terms and provision of the Plan and
this Restricted Stock Unit Award Agreement.  Following vesting, the Company will issue and transfer such Shares to the Participant as soon
as administratively feasible following satisfaction of any required withholding tax obligations as provided in Section 4 below.
Notwithstanding anything to the contrary set forth herein, but subject to Section 3 below, delivery of Shares pursuant to a Restricted
Stock Unit Award shall be made no later than 2-1/2 months after the close of Tekelec's first taxable year in which such Shares are no longer
subject to a risk of forfeiture (within the meaning of Section 409A of the Code).  


	To the extent the Restricted Stock Units vest and Shares are issued and delivered to the Participant, such
Shares will be free of the terms and conditions of this Restricted Stock Unit Award Agreement.


	No rights of a shareholder shall exist with respect to the Restricted Stock Units as a result of the mere grant of
the Restricted Stock Units.  Such rights shall exist only after issuance of the Shares following the applicable Vesting Date.


	Delivery of Shares upon Vesting of Restricted Stock Units.  Restricted Stock Units (if not previously
forfeited) will automatically be settled on or about the Vesting Date or Vesting Dates set forth on the cover page of this Restricted Stock Unit
Award Agreement.  The Company may make delivery of Shares upon vesting of Restricted Stock Units either by (i) delivering one or more
stock certificates representing such Shares to the Participant, registered in the name of the Participant, or (ii) depositing such Shares into an
account maintained for the Participant and established in connection with any Company plan or arrangement providing for investment in
Common Stock of the Company, including without limitation any on-line securities account maintained by the Participant with E*Trade
Securities LLC ("E*Trade") as an employee of Tekelec.  All certificates for Shares and all Shares shall be subject to such stop transfer orders
and other restrictions as the Company may deem advisable under the rules, regulations and other requirements of the Securities and
Exchange Commission, any stock exchange or quotation system upon which the Shares are then listed or quoted, and any applicable
Federal or state securities law, and the Company may cause a legend or legends to be put on any such certificates (or other appropriate
restrictions and/or notations to be associated with any accounts in which such Shares are held) to make appropriate reference to such
restrictions.


	Taxes. 



	Responsibility of the Participant.  The Participant is responsible for any taxes required to be withheld under
Federal, state or local law in connection with: (i) the vesting of the Restricted Stock





                                              3









Unit Award and the issuance and delivery of Shares
to the Participant, or (iii) any other event occurring pursuant to this Restricted Stock Unit Award Agreement or the Plan (collectively,
"Taxes").



	Payment in Cash.  The Participant may elect to pay to the Company an amount sufficient to cover such
Taxes by delivering to the Company a check or by such other means as the Company may establish or permit.


	Cashless Exercise.  Subject to the Participant's compliance with the company's policy on Insider Trading
and Tipping (as in effect from time to time), the Participant may elect to pay the Company his or her obligations for the payment of such
Taxes through a special sale and remittance procedure commonly referred to as a "cashless exercise" or "sell to cover" transaction pursuant
to which the Participant (or any other person(s) entitled to receive the Shares upon vesting) shall concurrently provide irrevocable written
instructions:



	to E*Trade (through the Participant's on-line account) to effect the immediate sale of a sufficient number of the
Shares acquired upon the vesting of the Shares to enable E*Trade to remit, out of the sales proceeds available upon the settlement date,
sufficient funds to Tekelec to cover all applicable federal, state and local income and employment taxes required to be withheld by Tekelec by
reason of such vesting and/or sale; and


	to Tekelec to deliver any certificate(s) or other evidence of ownership for such sold Shares directly to E*Trade in
order to complete the sale transaction.


	Payment by Withholding of Shares.  In the Company's sole discretion and in the lieu of Participant's
election under Section 4(c), the Company may elect to retain that number of whole Shares which would otherwise be deliverable in
connection with the Restricted Stock Unit Award upon vesting and which have a Fair Market Value sufficient to satisfy the amount of the
Taxes required to be withheld.  "Fair Market Value" for this purpose shall be as determined in the Plan as of the last trading day before the
applicable Vesting Date.


	Company Rights.  Any election pursuant to this Section 4 above shall be made in writing on such
form or electronically in such manner (including through a Participant's on-line E*Trade account) as shall be prescribed by the Company for
such purpose.  The Company also reserves the right to withhold Taxes, in accordance with any applicable law, from (i) any compensation or
other amounts payable to the Participant and/or (ii) the Shares otherwise issuable to the Participant.


	Termination of Employment.  If the Participant ceases to serve as an Employee for any reason and
thereby terminates his or her Continuous Status as an Employee, the Participant's Restricted Stock Units which are not vested as of the date
of such termination shall not vest and shall automatically be cancelled and forfeited for no value and without any issuance of Shares.



	Nontransferability of Restricted Stock Units.  This Restricted Stock Unit Award may not be sold, pledged,
assigned, hypothecated, gifted, transferred or disposed of in any manner either voluntarily or involuntarily by operation of law, other than
transfers between spouses incident to a divorce.  Subject to the foregoing and the terms of the Plan, the terms of this Restricted Stock Unit
Award shall be binding upon the executors, administrators, heirs, successors and assigns of the Participant.  The Shares issued upon vesting
of the Restricted Stock Unit Award will not be subject to restrictions on transfer under this Section 6.


	No Dividend Equivalents.  The Participant shall not be entitled to receive, currently or on a deferred
basis, any payments (i.e., "dividend equivalents") equivalent to cash, stock or other property paid by the Company as dividends on the
Company's Common Stock prior to the vesting of the Restricted Stock Units.

                                              4








	No Right of Employment.  Neither the Plan nor this Restricted Stock Unit Award shall confer upon the
Participant any right to continue in the employment of the Company or limit in any respect the right of the Company to discharge the
Participant at any time, with or without cause and with or without notice.


	Miscellaneous.

	Successors and Assigns.  This Restricted Stock Unit Award Agreement shall bind and inure only to the benefit of the parties to this
Restricted Stock Unit Award Agreement (the "Parties") and their respective permitted successors and assigns.


	No Third-Party Beneficiaries.  Nothing in this Restricted Stock Unit Award Agreement is intended to
confer any rights or remedies on any persons other than the Parties and their respective permitted successors or assigns.  Nothing in this
Restricted Stock Unit Award Agreement is intended to relieve or discharge the obligation or liability of third persons to any Party.  No
provision of this Restricted Stock Unit Award Agreement shall give any third person any right of subrogation or action over or against any
Party.


	Amendments.



	The Committee reserves the right to amend the terms and provisions of this Restricted Stock Unit Award without
the Participant's consent to comply with any Federal or state securities law.


	Except as specifically provided in subsection (i) above, this Restricted Stock Unit Award Agreement shall
not be changed or modified, in whole or in part, except by supplemental agreement signed by the Parties.  Either Party may waive
compliance by the other Party with any of the covenants or conditions of this Restricted Stock Unit Award Agreement, but no waiver shall be
binding unless executed in writing by the Party making the waiver.  No waiver or any provision of this Restricted Stock Unit Award Agreement
shall be deemed, or shall constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing
waiver.  Any consent under this Restricted Stock Unit Award Agreement shall be in writing and shall be effective only to the extent specifically
set forth in such writing.


	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 conflict of
laws rules thereof.


	Severability.  If any provision of this Restricted Stock Unit Award Agreement or the application of such
provision to any person or circumstances is held invalid or unenforceable, the remainder of this Restricted Stock Unit Award Agreement, or
the application of such provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be
affected thereby.
