regulatory agencies within ten (10) days of mailing or receipt of Regulatory Filings, Regulatory Documentation or communications, as the case may be, with a regulatory agency. TSD shall provide to PPD copies of all final clinical study reports. A
PPD JDC member shall have the right to consult with the JDC if the PPD JDC member reasonably believes information is needed from TSD in order to protect PPD’s interests, as the case may be, in the subject matter of this Agreement, and TSD
through the JDC shall reasonably cooperate in connection therewith. To accomplish its objectives, the JDC will meet quarterly, or more often if mutually agreed upon by the Parties, during the term of any Development Plan or during any period of
post-marketing regulatory activity, and will meet at least annually thereafter. The JDC may meet in person or by telephone or video conference. In-person JDC meetings will be held in Chicago, IL or such other sites that the Parties may mutually

 5.4 Costs and Expenses. The Parties shall apportion costs and expenses as follows: 
  
 (a) PPD shall be solely responsible for all direct and indirect
costs and expenses (including internal personnel and other internal costs and expenses) related to Phase II Trials pursuant to the Collaboration Agreement accrued prior to [*]; and 
  
 (b) TSD shall reimburse PPD for [*]% of all Phase III Development Costs accrued before [*] and PPD shall be
responsible for the remaining [*]% of such costs. 
  
 (c) Within six (6) months of the Effective Date, PPD shall submit a final request for reimbursement for any and all monies PPD seeks reimbursement for from TSD under Section 5.4(b) hereof. Schedule 5.4 lists all expenses that are
outstanding under Section 5.4(b) as of the Effective Date. TSD shall pay to PPD such amounts owed no later than thirty (30) days after receipt of such final request from PPD. 
  
 5.5 Third Party License Payments. If TSD, its Affiliates or licensees pay an upfront payment, milestone, royalty or
other payment to a Third Party in consideration for immunity from or license to such Third Party’s intellectual property rights with respect to the Product, then [*] percent ([*]%) of such payment shall be credited to TSD against the subsequent
royalty payment that comes due to PPD under Article 5, provided however, that no royalty payment to PPD under Article 5 shall be reduced by more than [*] percent ([*]%). For sake of clarity, a license to a specific pharmaceutical active ingredient
other than a Compound used in a Combination Product or a Takeda Combination Product shall not be treated as a Third Party License payment under this Section 5.5. Notwithstanding the foregoing, PPD shall reimburse TSD $500,000 for the [*].

  
 5.6 Payments Non-Refundable. All payments to PPD under
this Article 5 and Article 6 are noncreditable and nonrefundable, and TSD shall not have any right to set off any amounts provided to be paid under this Article 5 or Article 6.

Development, Inc., 3151 South 17th Street, Wilmington, North Carolina, 28412, Attn: Corporate Controller. The amount of royalty payment due to PPD shall be paid by TSD concurrently with the remittance of each royalty report. Interest shall accrue on
any payments due under this Agreement (including royalties) not paid when due through and including the date upon which PPD has collected the funds in accordance herewith at a rate equal to the lesser of (i) the sum of [*] percent ([*]%) plus the
prime rate of interest quoted in the Money Rates (or equivalent) section of The Wall Street Journal (or any substitute source mutually agreed to by the Parties), calculated daily on the basis of a three hundred sixty (360) day year, or (ii)
the maximum interest rate allowed by applicable law. Except as set forth in Section 6.3, payments pursuant to this Section 6.1(b) shall be made in U.S. dollars. 
  

6.2 Taxes. Each Party shall pay any and all taxes levied on account of all payments it receives under this Agreement. If laws or regulations
require that taxes be withheld, the paying Party will (a) deduct those taxes from the remittable payment, (b) pay the taxes to the proper taxing authority, and (c) send evidence of the obligation together with proof of tax payment to the non-paying
Party within thirty (30) days following that tax payment. Any such payments made by the paying Party shall be treated as having been made to the non-paying Party under this Article 6.

royalty payments pursuant to Section 5.3 arising from Net Sales made in that country shall be paid to PPD in the country in local currency by deposit in a local bank designated by PPD, unless the Parties otherwise agree. 
  
 6.4 Foreign Exchange. Conversion of sales recorded in local currencies to
U.S. dollars will be done for such currencies using the average rate of exchange for the applicable quarter based upon the daily rates for such currencies at the time published in The Wall Street Journal (or any substitute source mutually
agreed to by the Parties). 
  
 6.5 Records; Inspection. TSD
shall keep, and shall require its Permitted Sellers to keep, complete, true and accurate books of accounts and records for the purpose of determining the basis and accuracy of payments to be made under this Agreement. Such records shall be kept in
accordance with generally accepted accounting principals, showing Net Sales of Product on a country-by-country and Product-by-Product bases, and TSD’s or its Permitted Sellers’ usual internal practices and procedures, consistently applied.
Such books and records shall be kept for at least five (5) years following the end of the calendar quarter to which they pertain. Such records will be open for inspection by PPD during such five (5) year period by independent accountants reasonably
acceptable to TSD, solely for the purpose of verifying the basis and accuracy of amounts in the payment statements hereunder. Such inspections shall be made no more than once each calendar year, at reasonable time and on reasonable notice and shall
be limited to information related to Products. Results of any such inspection shall be deemed to be Confidential Information of TSD. If any errors in favor of TSD are discovered in the course of such inspection, then within thirty (30) days of
written request by PPD, TSD shall pay PPD those amounts that PPD would 
  


	[*]	Confidential treatment requested; certain information omitted and filed separately with the SEC. 








 have received in the absence of such errors, plus interest pursuant to and in accordance with Section
6.1(b). Inspections conducted under this Section 6.5 shall be at the expense of PPD, unless a variation or error in favor of TSD exceeding [*] percent ([*]%) of the amount stated for the period covered by the inspection is established in the course
of such inspection, whereupon all costs relating to the inspection for such period will be paid promptly by TSD.

NEGLIGENCE, STRICT LIABILITY OR OTHER TORT, OR OTHERWISE ARISING OUT OF THIS AGREEMENT, PROVIDED HOWEVER, THAT THE FOREGOING SHALL NOT PRECLUDE A CLAIM BY PPD FOR DAMAGES CAUSED BY A MATERIAL BREACH BY TSD OF ITS OBLIGATIONS UNDER THIS
AGREEMENT FOR THOSE PAYMENTS THAT PPD WOULD HAVE REALIZED PURSUANT TO ARTICLE 5 HAD TSD COMPLIED WITH ITS OBLIGATIONS UNDER THIS AGREEMENT. 
  
 7.5 Payment of Indemnification. Upon the final, unappealable determination of liability and the amount of the indemnification payment under this

 ARTICLE 12 
  
 PPD OPTION TO PPD PRODUCTS 
  
 12.1 PPD Option #1 to Develop PPD Products. PPD may elect to pursue the development and commercialization of one or more of SYR110322, SYR110619, [*] as a PPD Product at such time that TSD is not
actively developing or commercializing at least one of SYR110322, SYR110619, [*] (“PPD Option #1”). 
  
 12.2 PPD Option #2 to Develop PPD Products. In the event that (a) PPD provides TSD with notice that a material breach has occurred under the Agreement with regard to TSD’s failure to use
Diligent Efforts to develop SYR110322, SYR110619, [*]; (b) TSD does not make substantial sustained efforts to effect a cure of such material breach within ninety (90) days of receipt of such written notice by PPD where such substantial sustained
efforts are reasonably likely to cure such breach; and (c) PPD provides notice that that such material breach has not been cured, then PPD may pursue the development and commercialization of the Compound that was the subject of the material breach
as a PPD Product if PPD provides notice to TSD within one (1) year from the date of written notice of such material breach (“PPD Option #2”). 
  
 12.3 PPD Election to Develop PPD Products. PPD may elect to exercise PPD Option #1 or PPD Option #2 by providing TSD with written notice indicating
the Compound(s) from among SYR110322, SYR110619, [*] which PPD desires to develop and commercialize. The Parties agree to make an appropriate filing with the Federal Trade Commission under the HSR Act, if necessary, as soon as practicable upon the
receipt by TSD of an election by PPD under this Section 12.3, and shall use their best efforts to expedite such filing. The Parties will share equally the HSR Act filing fee and will request early termination of the waiting period. 
  
 12.4 License to PPD regarding PPD Products. Subject to the terms of this
Agreement, TSD will grant to PPD as of the Effective Date a perpetual, royalty bearing, worldwide, exclusive (even as to TSD) license, with right to grant sublicenses, to all Intellectual Property owned or otherwise Controlled by TSD or its
Affiliates related to SYR110322, SYR110619, [*], to develop, make, have made, use, import, offer for sale and sell Products comprising SYR110322, SYR110619, [*] (the “PPD License”). To the extent that TSD is unable to grant an
exclusive license to any Intellectual Property Controlled by TSD or an Affiliate of TSD, such license granted by TSD to PPD will be non-exclusive with respect to such Intellectual Property. The PPD License granted by TSD to PPD pursuant to this
Section 12.4 is conditioned upon and shall only become 
  


	[*]	Confidential treatment requested; certain information omitted and filed separately with the SEC. 








 effective on a Compound by Compound basis following the exercise of PPD Option #1 or PPD Option #2 pursuant
to Sections 12.1-12.3, subject to the expiration or earlier termination of any notice and waiting period under the HSR Act, if necessary. Any costs not otherwise reimbursed by PPD for licenses to Third Party intellectual property rights acquired
pursuant to Section 5.5, to the extent transferred (TSD does not assure their transferability) from TSD to PPD at PPD’s request, shall be immediately reimbursed by PPD. 
  
 12.5 TSD Obligations Following PPD’s Exercise of Option #1 or Option #2. At such time that PPD exercises PPD Option
#1 or PPD Option #2 pursuant to Section 12.3, the PPD License shall become effective. Promptly following effectiveness of the PPD License, TSD shall deliver to PPD any and all data and documentation in TSD’s Control relating to the development
of such elected Compound. TSD shall also promptly notify PPD if it later discovers any data or documentation in TSD’s Control related to the development of such elected Compound that was not previously delivered to PPD and shall promptly
deliver such to PPD. TSD shall also transfer to PPD the legal title to the associated INDs presently on file and any comparable filings in other countries of the Territory for such elected Compound. TSD shall also transfer to PPD ownership of all
Drug Substance, CTM and Finished Product of such elected Compound and any other Material in TSD’s possession as of the time such option is exercised. 
  
 12.6 Control over development of PPD Products. Following the effectiveness of the PPD License, PPD shall have the right, at its sole discretion and
expense, to develop and commercialize such elected Compound. PPD shall be free to select Affiliates, licensees and subcontractors, in its sole discretion, to develop and commercialize PPD Products for such elected Compound, provided however, that
PPD shall be liable for all of its obligations under this Article. PPD shall also provide TSD with the same indemnification protection as TSD affords to PPD pursuant to this Agreement for Products. 
  
 12.7 Payments to TSD for PPD Products. In regard to any Compound(s) from
among SYR110322, SYR110619, [*] that PPD exercises Option #1 or PPD Option #2 pursuant to Section 12.3, then effective as of when PPD exercises such option, PPD shall have the same Milestone Payment and Royalty obligations to TSD that TSD would have
had to PPD under Article 5 of this Agreement if it were TSD developing such PPD Product instead of PPD. PPD shall pay TSD out of Net Sales of PPD Products all costs in regard to Drug Substance, CTM and Finished Product of such elected Compound and
any other Material transferred to PPD pursuant to Section 12.5. 
  
 12.8 Reversion to TSD absent PPD Diligent Efforts All rights granted to PPD under this Article shall be subject to reversion to TSD at any such time that PPD fails to utilize Diligent Efforts to develop and commercialize such elected
Compound or materially breaches its obligations under this Article including the payment obligations set forth in Section 12.7. 
  
 12.9 Exercise of PPD Option #2 not exclusive remedy. The Parties agree that PPD’s exercise of PPD Option #2 pursuant to Section 12.3 based on a
material breach shall not be exclusive or prejudicial to any other rights or remedies that PPD may otherwise have on account of the failure of TSD to use Diligent Efforts to develop SYR110322, SYR110619, [*]. 
  


	[*]	Confidential treatment requested; certain information omitted and filed separately with the SEC. 








 12.10 Specific Performance as Remedy for Breach of Section 12.5. The Parties agree that following
PPD’s proper exercise of PPD Option #1 or PPD Option #2 pursuant to Sections 12.1-12.3, should TSD fail to reasonably comply with its obligations under Section 12.5, then, following such breach, PPD shall have the right to seek specific
performance by TSD of its obligations under Section 12.5.

 Takeda Acquires the Rights to DPP4 Inhibitors Granted to
PPDI 
  
 Osaka, Japan/Wilmington, N.C., July
xx, 2005 — Takeda Pharmaceutical Company Limited (“Takeda”) and PPD, Inc. (Nasdaq: PPDI) today announced an agreement in which Takeda acquired the development and marketing rights to all dipeptidyl peptidase IV (DPP4) inhibitors
previously granted to PPD under an agreement between PPD and Syrrx, Inc. Takeda acquired Syrrx, Inc., now known as Takeda San Diego, Inc., in March 2005. 
  
 Under the new agreement, Takeda, through Takeda San Diego, acquired all the remaining rights to develop and commercialize the DPP4
inhibitors, which rights had been shared by PPD and Takeda San Diego under the collaboration agreement dated November 19, 2003. In exchange for terminating the collaboration agreement and transferring its rights to Takeda, PPD will receive an
upfront payment of US$15.0 million, plus development and sales milestones, and royalties on sales of DPP4 inhibitors if approved for marketing. 
  
 The agreement further provides that PPD will serve as the sole provider to Takeda of Phase II and Phase III clinical development services in
the US and the EU for the DPP4 inhibitors. This will enable the DPP4 development program to continue without interruption. Further details of the financial terms of the agreement were not disclosed. 
  
 A variety of pre-clinical and clinical findings to date indicate
DPP4 inhibitors have the potential to treat type 2 diabetes. DPP4 degrades GLP-1 (Glucagon-like peptide-1), an important hormone that is released in response to the intake of food and that stimulates pancreatic beta cells to increase the secretion
of insulin and that has potential to improve beta cell function itself. DPP4 inhibitors, taken orally, work by blocking GLP-1 degradation to keep its concentration for a longer period of time. Therefore, DPP4 inhibitors are expected to be one of the
new generation agents for diabetes treatment. 
  
 “We are pleased to reach this agreement with PPD, allowing us full rights to DPP4 inhibitors created by our new colleagues at Takeda San Diego,” said Yasuchika Hasegawa, President & Chief Operating Officer of Takeda. “We
believe that these DPP4 inhibitors will enhance Takeda’s diabetes franchise in the future”. 
  
 “We too are excited with the new arrangement with Takeda for the continued development and commercialization of the DPP4 assets,”
said Fred Eshelman, Chief Executive Officer of PPD. “With the signing of this agreement, this becomes the second program under which we have advanced the clinical development of a compound and then transferred it to a third party for continued
development and commercialization, thereby further validating our compound partnering strategy. As a worldwide leader in diabetes medicines, we believe that Takeda is an outstanding partner for this program.”

 7.3 Indemnification Procedure. 
  

	 	(a)	If any action is brought against a party entitled to indemnification under Section 7.1 or 7.2, as applicable, (each, an “Indemnified Party”), such
Indemnified Party or Parties shall promptly notify the party obligated to provide indemnification (an “Indemnifying Party”) in writing of the institution of such action. 

  

	 	(b)	Promptly upon receipt of notice pursuant to subparagraph (a) above, the Indemnifying Party shall promptly assume the defense of such action, including, without
limitation, the employment of counsel reasonably satisfactory to such Indemnified Party or Parties, and payment of expenses. An Indemnified Party or Parties shall have the right to employ its or their own counsel in any such case, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or Parties, unless: 

  

	 	(i)	the employment of such counsel shall have been authorized in writing by the Indemnifying Party in connection with the defense of such action; or


  

	 	(ii)	the named parties to such action include both the Indemnified Party or Parties and the Indemnifying Party and such Indemnified Party or Parties shall have reasonably

 (c) Notwithstanding anything contained in this Section 7.3 to the contrary, the Indemnifying Party shall not be liable for any
settlement of any such claim or action effected without its written consent, which consent shall not be unreasonably withheld. The Indemnifying Party shall have the right to settle or compromise any action, or permit a default or consent to the
entry of judgment in, or otherwise seek to terminate, any pending or threatened action, in respect of which indemnity may be sought hereunder (whether or not any Indemnified Party is a party thereto), provided such settlement, compromise,
consent, or termination includes an unconditional release of each Indemnified Party from all liability in respect of such action. In the event such an unconditional release is not obtainable for each Indemnified Party, then the Indemnifying Party
must obtain the prior written consent of any Indemnified Party not so released before the Indemnifying Party may enter into such settlement, compromise, consent or termination. 







 8. PPD represents and warrants that the Sites listed under “Phase II Clinical Research
Agreements and Letters of Indemnification” on Schedule 7.1 have not executed contracts with third party providers for services performed under the respective Clinical Research Agreements for Protocol [*] entitled, “[*]”.
