distributed at no cost to Affiliates or otherwise for bona fide business, scientific or charitable
reasons (including without limitation in connection with clinical trials, compassionate sales or an

to the reasonable approval of ProQuest. 1.27 Patent Rightsshall mean all patents and patent applications and foreign counterparts

Compound in lieu of PQ-1002, in which event Guilford shall use Commercially Reasonable Efforts to
so Develop and Commercialize such Agreement Compound (subject to Section 2.2 above and Sections
5.3(d) and 6.4(i) below). Guilford, either directly or through any corporate partner(s) it
chooses, shall be responsible for paying all expenses associated with the Development and
Commercialization of PQ-1002 (or any other Agreement Compound, if applicable). If and when PQ-1002 (or another Agreement Compound, if applicable) has been successfully

PQ-1002 (Royalty) in the following amounts:  (i)
    five percent (5%) of Net Sales on the first One Hundred Million
Dollars ($100,000,000) in worldwide Net Sales in any calendar year;(ii)
    seven percent (7%) on the next One Hundred Million Dollars (i.e.,
between $100,000,000 and $200,000,000) in worldwide Net Sales in any calendar
year; and(iii)
    nine percent (9%) on all amounts of worldwide Net Sales in
excess of Two Hundred Million Dollars ($200,000,000) in any such calendar year. 6.2 Third Party Royalty Credit. On a country by country basis, fifty percent (50%) of any
Third Party Royalties paid by Guilford will be creditable against Royalties payable to ProQuest
under this Agreement. Credit for Third Party Royalties will be made on a quarterly basis;
provided, however, that no such credit shall reduce the amount of Royalties paid by Guilford for a
particular calendar quarter by more than 50%. 6.3 Term of Royalty.Royalty will be payable on a country by country basis until the last to
expire of the patent or patents in such country covering PQ-1002, and, in a country where no patent
ever issued covering PQ-1002, then until the last to expire of the patent or patents in the U.S.,
France, Germany or the United Kingdom covering PQ-1002. 6.4 Reports and Payments. (a) Cumulative Royalties.The obligation to pay Royalties under this Article 6 shall be
imposed only once (i) with respect to any sale of the same unit of Program Product; and (ii) with
respect to a single unit of Program Product regardless of how many valid issued or, assuming they
were to issue, patent claims included in Program Patent Rights would be infringed by Third Parties
by the making, using or selling of such Program Product. (b) Statements and Payments.Guilford shall deliver to ProQuest within sixty (60) days after
the end of

##### 



each calendar quarter, a statement certified by Guilford as accurate to the best of its ability
based on information available to Guilford, setting forth for the previous quarter the following
information on a country-by-country basis: (i) Net Sales of Program Products; (ii) the basis for
any Royalty adjustments; and (iii) the Royalty due hereunder, which report shall be accompanied by
a remittance of the Royalty due. (c) Interest.If Guilford fails to pay undisputed Royalty within fifteen (15) days of the
date such Royalty is due, Guilford shall pay interest on the amount of such overdue Royalty (from
the original due date) at the rate of 10% per annum until it is paid in full. If any disputed
Royalty withheld by Guilford is later determined to have been properly owing as of the original due
date, Guilford shall likewise pay interest on the amount of such Royalty withheld at such interest
rate from the original due date until date of payment. (d) Taxes.All taxes levied on account of Royalties accruing under this Agreement shall be
paid by ProQuest. If laws or regulations require withholding of taxes from any payment by Guilford
to ProQuest hereunder, the taxes will be deducted by Guilford from remittable Royalty to ProQuest
and will be paid by Guilford to the proper taxing authority. Guilford will furnish ProQuest with
the original copies of all official receipts for such taxes. In the event of any such withholding,
the Parties agree to confer and cooperate in good faith regarding any filings with tax authorities
and other measures that may be taken to minimize the amount of any such withholding. (e) Currency.All amounts payable and calculations hereunder shall be in United States
dollars, and all payments under this Article 6 shall be made to ProQuest. As applicable, Net Sales
shall be translated into United States dollars at the rate of exchange at which United States
dollars are listed in International Financial Statistics (publisher, International Monetary Fund)
or if it is not available, The Wall Street Journal for the currency of the country in which the
sale is made at the average of the calendar quarter in which such sales were made. (f) Audit.Guilford shall maintain (and shall cause its Affiliates and sublicensees to
maintain) books and records as necessary to allow the accurate calculation of Royalties due
hereunder including any records required to calculate any Royalty adjustments hereunder. Once per
year ProQuest shall have the right to engage an independent accounting firm reasonably acceptable
to Guilford, at ProQuests expense, which shall have the right to examine in confidence during
normal business hours the relevant Guilford records in order to determine and/or verify the amount
of Royalty payments due hereunder. Should such accountants representing ProQuest deem it necessary
to examine the books and records of any sublicensee of Guilford in connection with such an audit,
the parties agree to cooperate and to reasonably exercise Guilfords right of access under its
agreement with such sublicensee, so as to minimize any disruption in Guilfords relations with such
sublicensee. Such independent auditor will prepare a report confirming or challenging the
Royalties paid by Guilford for any of the preceding three (3) annual periods (except any period
which has previously been subject to audit thereunder). In the event there was an under-payment by
Guilford hereunder, Guilford shall promptly make payment to ProQuest of any short-fall (with
interest specified under Section 6.4(c). In the event that there was an over-payment by Guilford
hereunder, Guilford shall credit the excess amount against future payments. In the event any
payment by Guilford shall prove to have been incorrect by more than seven-and-a-half percent (7.5%)
to ProQuest detriment, Guilford will reimburse ProQuest for its reasonable fees and costs of such
independent auditor. (g) Record Retention.Guilford shall keep complete and accurate records in sufficient detail
to permit ProQuest to confirm the accuracy of calculations of all payments hereunder. Such records
shall be retained by Guilford for no less than a three (3) year period following the year in which
any such payments were made hereunder, provided, however, that if there is a good faith dispute
between the parties continuing at the end of any such three (3) year period with respect to such
books and records, then the time period for RPR to maintain such books and records under dispute
shall be extended until such time as the dispute is finally resolved. (h) Survival.Subsections (f) and (g) of this Section 6.4 shall survive any termination of
this Agreement for the period set forth therein.

or otherwise agreed in writing, the Parties agree that, for the term of this Agreement and for five
(5) years thereafter, each Party receiving hereunder any Confidential Information (the Receiving
Party) of the other Party pursuant to this Agreement (the Disclosing Party), and ProQuest, with
respect to ProQuest Patent Rights and ProQuest Know-how that is Confidential Information, shall
keep such Confidential Information confidential and shall not publish or otherwise disclose or use
such Confidential Information for any purpose, except to the extent that it can be established by

    was already known to the Receiving Party, other than under an
obligation of confidentiality, at the time of disclosure by the Disclosing Party
and such Receiving Party has documentary evidence to that effect;(ii)
    was generally available to the public or otherwise part of the
public domain at the time of its disclosure to the Receiving Party;(iii)
    became generally available to the public or otherwise part of
the public domain after its disclosure or development, as the case may be, other
than through a breach by the Receiving Party of this Section 7.1;(iv)
    was disclosed to the Receiving Party, other than under an
obligation of confidentiality, by a Third Party who had no obligation to the
Disclosing Party not to disclose such information to others; or(v)
    was independently discovered or developed by the Receiving Party
without reference to any information or material disclosed hereunder, and this
is provable by documentary evidence.

7.2 Authorized Disclosure and Use. (a) Guilford.Guilford may disclose Confidential Information of ProQuest received from
ProQuest or a Third Party to the extent such disclosure is reasonably necessary in filing or
prosecuting patent applications, prosecuting or defending litigation, complying with applicable
governmental regulations or conducting preclinical or clinical trials, provided that if Guilford is
required by law or regulation to make any such disclosure of ProQuests Confidential Information,
Guilford will, except where impracticable for necessary disclosures (for example in the event of
medical emergency), give reasonable advance notice to ProQuest of such disclosure requirement and
will where applicable use its reasonable efforts to seek confidential treatment of such
Confidential Information required to be disclosed. In addition, Guilford shall be entitled to
disclose, under customary conditions of confidentiality similar to these contained in this Article
7, Confidential Information of ProQuest received from ProQuest, its Affiliate or a Third Party, in
connection with Guilfords performance under this Agreement to Develop and Commercialize PQ-1002 or
any other Agreement Compound, for purposes of conducting discussions with potential licensees,
investors, financial institutions, potential merger or acquisition partners or other advisers.
ProQuest understands that Guilford may file this Agreement and related agreements as exhibits to

defending litigation or (if and after ProQuest becomes a public company) complying with applicable
securities regulations, provided that if Guilford is required by law or regulation to make any such
disclosure of Guilfords Confidential Information, ProQuest will, except where impracticable for
necessary disclosures, give reasonable advance notice to Guilford of such disclosure requirement
and will where applicable use its reasonable efforts to seek confidential treatment of such
Confidential Information required to be disclosed. ProQuest agrees to consult in good faith with
Guilford on the nature and scope of public references to Guilford in connection with any filings
required of ProQuest by law. ProQuest may disclose non-public (i) ProQuest Patent Rights and
ProQuest Know-how in existence prior to the Effective Date, and (ii) ProQuest Patent Rights and
ProQuest Know-how which come into existence from and after the Effective Date, so long as it does
not relate to Agreement Compounds, in each case under customary conditions of confidentiality
similar to those contained in this Article 7, for purposes of conducting discussions with potential
licensees, investors, financial institutions, potential merger or acquisition partners or other
advisers. 7.3 Termination of Prior Agreement.This Agreement supersedes the Confidentiality Agreement
between ProQuest and Guilford, dated January 12, 1999. All confidential information received by a
Party from the other under that agreement shall be deemed Confidential Information received under
this Agreement by a Receiving Party from a Disclosing Party and shall be subject to the terms of
this Article 7. 7.4 Publications.Except as provided in this Section 7.4, ProQuest shall not publish or
otherwise disclose non-public ProQuest Patent Rights or ProQuest Know-how relating to PQ-1002 or
other Agreement Compounds in an academic, scientific or medical publication without Guilfords
prior written consent. Guilford shall not in any event consent without being supplied a copy of
the proposed publication or disclosure at least thirty (30) days prior to intended submission for
publication or for oral presentation. Notwithstanding the first sentence of this Section 7.4,
ProQuest may publish preclinical data relating to PQ-1002 in existence as of the Effective Date,
provided Guilford is given at least thirty (30) days to review such manuscript or other disclosure
and to discuss any concerns with ProQuest, and provided further that ProQuest may not publish the
chemical structure of PQ-1002 (unless it has been previously publicly disclosed through no fault of
ProQuest). Subject to the other terms and conditions of this Agreement, each Party will comply with
standard academic practice regarding authorship of scientific publications and recognition of
contribution of other parties in any publications relating to Agreement Compounds.

reasonable opportunity to review and comment prior to release of such public announcement.
Guilford may make any public announcements it deems necessary or desirable under state and federal
securities laws concerning this Agreement and the Development and Commercialization of an Agreement
Compound. ProQuest, if it becomes and for so long as it remains a public company, may make any
public announcements it deems necessary or desirable under state and federal securities laws
concerning this Agreement. Subject to the foregoing two sentences and Section 7.2 above, Guilford
agrees to consult in good faith with ProQuest to agree on the nature and scope of Guilfords public
references to ProQuest, its shareholders, KUCR, and the University of Kansas, and ProQuest agrees
to consult in good faith with Guilford to agree on the nature and scope of ProQuests public

reasonable supporting documentation, provided that: (i) for the avoidance of doubt, Guilford shall
not reimburse ProQuest for any expenses or reimbursement obligations incurred for Patent
Prosecution of patents or patent applications that do not claim a composition of matter, use,
method, process or other matter relating to Agreement Compounds; and (ii) to the extent ProQuest
licenses Third Parties under a patent and/or patent application included in ProQuest Patent Rights
for compounds other than Agreement Compounds (for example, for prodrugs of camptothecin in the

expenses for such patent and/or patent application, based on the number of licensees under such
patent and/or patent application included in ProQuest Patent Rights. (c) Guilford.Guilford shall at its cost be responsible for and control the Patent
Prosecution of Program Patent Rights described in Section 8.1(ii) and (iii) above, and such other

ProQuest Patent Rights, Guilford shall give ProQuest sufficient notice to afford ProQuest the
opportunity to do so at ProQuests cost, in which event, ProQuest will own such ProQuest Patent
Rights, free and clear of any license to Guilford under this Agreement. (d)ProQuest agrees to use commercially reasonable efforts, in consultation with Guilford, to
diligently conduct Patent Prosecution of ProQuest Patent Rights in a manner so as to preserve and

---



##### 



(a) Guilford.Guilford shall have the right but not the obligation, in its own name, to
enforce Program Patent Rights against any Third Party suspected of infringing a claim of Program
Patent Rights, subject, to the extent applicable, to the terms of Article 8 of the KU License, as
amended by the Consent and Agreement. Guilford shall have exclusive control over the conduct of
any such proceedings, including the right to settle or compromise such proceedings, subject, to the
extent applicable, to the terms of Article 8 of the KU License, as amended by the Consent and
Agreement. Subject to Guilfords right to be reimbursed out of any award or recovery under Section
8.3(b) below, the expense of any proceeding Guilford initiates, including lawyers fees and costs,
shall be borne by Guilford. ProQuest agrees to cooperate (at Guilfords expense for ProQuests
out-of-pocket expenses) with Guilford in such action as Guilford may reasonably request. (b) Disposition of Any Award or Recovery.Any award or recovery paid to Guilford by a Third
Party as a result of such patent infringement proceedings (whether by way of settlement or
otherwise) shall: (i) first be applied toward reimbursement of legal fees, costs and expenses
incurred by the Parties in proportion to their out-of-pocket expenditures of such fees, costs and
expenses; and (ii) second, from the remainder, if any, Guilford shall pay to ProQuest an amount
equal to the applicable Royalty rate as applied to the remainder as though such remainder were Net
Sales of Program Products in the year in which the award or recovery is received. (c) ProQuest.ProQuest shall by its own counsel and at its own expense have the right to
participate and be represented in any such proceeding that Guilford initiates regarding ProQuest
Patent Rights described in Section 8.3(a) above. In the event that Guilford does not initiate an
action to enforce Program Patent Rights against a Third Party suspected of infringing a claim of
ProQuest Patent Rights, ProQuest may give notice to Guilford that ProQuest intends to bring such
enforcement action at ProQuests own expense. In such event, the Parties shall confer, and if
Guilford has a commercially reasonable basis for foregoing or delaying such infringement
proceeding, then Guilfords decision shall govern, provided, however, in determining whether there
is a commercially reasonable basis for Guilfords decision, any interest (direct or indirect) held
by Guilford in the suspected infringer shall be disregarded. Any recovery made by ProQuest from a
Third Party pursuant to any infringement action ProQuest brings as contemplated in this Section
8.3(c) will be allocated as if it were recovered by Guilford under Section 8.3(b) above and the
Consent and Agreement. 8.4 Infringement Defense.Guilford shall defend and control any suit against any of Guilford,
Guilfords Affiliates or sublicensees, ProQuest and/or ProQuests Affiliates alleging infringement
of any patent or other intellectual property right of a Third Party arising out of the manufacture,
use, sale, offer to sell or importation of a Program Product by Guilford, Guilfords Affiliates or
sublicensees. Guilford shall be responsible for all costs, expenses and damages, including
lawyers fees and costs, associated with any such suit or action, and shall indemnify ProQuest
against any losses, claims or damages ProQuest may suffer or incur as a result of such infringement
defense, provided that (i) Guilford shall be entitled to a 50% credit (with excess credit carrying
over to future payment obligations) toward any Milestone Payments (whether for stock of ProQuest
under the Stock Purchase Agreement or otherwise) or Royalty under Article 5 or 6 above for all such
costs, expenses, damages and indemnity reimbursement obligations actually paid by Guilford; (ii)
for any item of cost, expense, damage or reimbursement paid by Guilford, the credit described in
clause (i) shall only apply to Milestone Payments or Royalties that become due after Guilford pays
such item; and (iii) for the avoidance of doubt, any prospective royalty obligation mandated by any
settlement, judgment or award will be treated as Third Party Royalty under Section 6.2 above. 8.5 Cooperation Among the Parties.Subject, to the extent applicable, to the terms of the KU
License, as amended by the Consent and Agreement: (i) neither Party shall admit the invalidity or
unpatentability of any ProQuest Patent Rights or take any other action that may diminish the scope
of protection for Agreement Compounds without the other Partys prior written consent (such consent
not to be unreasonably withheld) in any action taken in the prosecution of, or in the defense of an
action by a Third Party alleging patent invalidity or unpatentability of any patent application or
patent included among the ProQuest Patent Rights; (ii) with respect to Patent Prosecution conducted
by Guilford of ProQuest Patent Rights, Guilford shall provide ProQuest sufficient time before the
due date and filing thereof, to review and comment on patent applications and patents and material
correspondence to and from the U.S. Patent and Trademark Office and foreign patent offices; (iii)
the Parties agree to cooperate with each other and to use best efforts to ensure the cooperation of
any of their respective personnel and licensee(s) or licensor(s) as might reasonably be requested
in any such matters, and shall sign any necessary legal papers and provide the prosecuting party
with useful data or other information; (iv) the Parties will confer on what action to take with
respect to the defense of infringement proceedings naming both Guilford and ProQuest or in




---



##### 



proceedings to enforce patents claiming the ProQuest Patent Rights against a Third Party; (v)
except to the extent Patent Prosecution rights are granted to ProQuest in Section 8.2(a) above, if
the Parties cannot agree on the course of action to be taken in the Patent Prosecution of any
Program Patent Rights or in the defense of any Third Party infringement action, Guilfords
decisions shall control; and (vi) each Party agrees to bring to the attention of the other Party
any patent or patent application it discovers, or has discovered, and which relates to the subject
matter of this Agreement. 8.6 Foreign Filings.The Parties shall consult with each other concerning the scope of
filings of ProQuest Patent Rights, and ProQuest shall cause ProQuest Patent Rights it is
prosecuting under Section 8.2 above to be filed in those countries designated by Guilford, provided
that each Party shall use Commercially Reasonable Efforts to cause ProQuest Patent Rights to be
filed at least in the United States, Europe, Canada and Japan. In the event ProQuest elects to
file ProQuest Patent Rights in countries other than those designated by Guilford, then Guilford
shall be relieved of its reimbursement obligations under Section 8.2(b) above for such ProQuest
Patent Rights in such countries; and ProQuest shall own such ProQuest Patent Rights free and clear
of any license to Guilford under this Agreement. Guilford shall have the final discretion with
respect to the ultimate geographic scope of filing of Guilford Patent Rights. 8.7 Patent Assignment.ProQuest will not assign its rights under any jointly owned Program
Patent Rights except with the prior written consent of Guilford, provided that ProQuest may assign
such rights without consent to an Affiliate or other permitted assignee under this Agreement in
connection with a merger or similar reorganization or the sale of all or substantially all of its
assets, as provided in Section 13.1 below. 8.8 No Warranty Respecting Patents.No Party makes any warranty with respect to the validity,
perfection or dominance of any Patent or other proprietary right or with respect to the absence of
right in Third Parties which may be infringed by the manufacture, sale or other use of any Program
Product. ARTICLE 9. REPRESENTATIONS AND WARRANTIES 9.1 Representations and Warranties of ProQuest.Except as set forth on the Disclosure

(d) Subject to Section 13.5, if Guilford has not, directly or through a partner, filed the
first NDA for PQ-1002 no later than the fifth anniversary of the Determination Date. The Parties agree that (c) and (d) above shall not apply in the event Guilford has decided to

except as otherwise specifically provided in this Agreement, Guilford shall have no further or
additional right and license to use the ProQuest Patent Rights, ProQuest Know-how or Confidential
Information of ProQuest. Notwithstanding the foregoing, Guilford shall have a limited right and
license to use such ProQuest Patent Rights, Pro-Quest Know-how or Confidential Information solely
to complete any Regulatory Filings required by law, to make any disclosures required by law,
including state and federal securities laws, and in connection with the marketing, distribution and
sale of all of its inventory of the Program Products existing as of the date of termination of this
Agreement for a six (6) month period following such date of termination. (b) Transfer of Certain Information.Subject to Section 10.4(d) below, Guilford shall within

covered by Guilford Patent Rights or Guilford Know-how, provided that nothing herein shall be
deemed to be a license by Guilford to ProQuest of any other Patent Rights of Guilford. In such
case, Guilford shall within 60 days following any such termination disclose or make available to
ProQuest Guilford Know-how in Guilfords Control as of such termination necessary to utilize any
such process contemplated in (ii) above. Notwithstanding Section 7.1, ProQuest may then disclose
non-public Guilford Patent Rights or Guilford Know-how contemplated in the preceding sentence under
customary conditions of confidentiality similar to those contained in Article 7 for purposes of
conducting discussions with potential licensees, investors, financial institutions, merger or
acquisition partners or other advisers. (d) Termination Due to ProQuests Breach.In the event this Agreement is terminated by
Guilford pursuant to Section 10.2(a), the provisions of Section 10.4(a) through (c) shall not
apply, and Section 10.4(e) shall apply to ProQuest, but not to Guilford, and without limiting any
other remedies Guilford may have against ProQuest, Guilford shall have a permanent, exclusive
worldwide license under ProQuest Patent Rights and ProQuest Know-how to Develop and Commercialize
any Agreement Compound then in Development or Commercialization, subject to Guilford making the
payments to ProQuest in the amounts and at the times provided in Articles 5 and 6. (e) Return or Destruction. Subject to Section 10.4(d) above, each Receiving Party shall
promptly return to the Disclosing Party or destroy all tangible embodiments of Confidential
Information received from the Disclosing Party, and all tangible embodiments of Program Patent

(f) Accrued Rights, Surviving Obligations.Unless explicitly provided otherwise in this
Agreement, termination, relinquishment or expiration of the Agreement for any reason shall be
without prejudice to any rights which shall have accrued to the benefit to either Party prior to
such termination, relinquishment or expiration, including damages arising from any breach under
this Agreement. Such termination, relinquishment or expiration shall not relieve any Party from
obligations which are expressly indicated to survive termination or expiration of the Agreement. (g) Sublicensee Rights.In the event that this Agreement and/or the rights and licenses
granted under this Agreement to Guilford are terminated, any sublicense granted under this
Agreement shall remain in full force and effect as a direct license between ProQuest and the
sublicensee under the terms and conditions of the sublicense agreement, subject to sublicensee (i)
curing any breach by Guilford, if such termination was due to a breach by Guilford, and (ii)
agreeing in writing to be bound to ProQuest under such terms and conditions as well as those
related to indemnification and confidentiality contained in Articles 7 and 11 hereof within thirty
(30) days after ProQuest provides written notice to sublicensee of the termination of Guilfords
rights and licenses under this Agreement, provided that the financial terms are no less favorable
to ProQuest, and ProQuests obligations under such sublicense are no greater, than currently
existing under this Agreement. At the request of Guilford, ProQuest will acknowledge to a
sublicensee, ProQuests obligations to sublicensee under this Section 10.4(f). ARTICLE 11. INDEMNIFICATION 11.1 Indemnification by Guilford.Guilford will defend and indemnify ProQuest, its
officers, directors, employees, and agents and hold them harmless from all liability, loss, damage
and cost arising out of (i) any claims of any nature (excluding claims by Third Parties relating to
patent infringement, except to the extent and subject to the terms specifically set forth in
Section 8.4 above) arising out of the research, Development or Commercialization of any Agreement
Compound (or any Program Product or any other product that contains an Agreement Compound) by, on
behalf of or under the authority of Guilford, or (ii) any breach of Guilfords representations or
warranties under this Agreement. 11.2 Indemnification by ProQuest.ProQuest will indemnify Guilford, its officers, directors,
employees, agents, and licensees and hold them harmless from all liability, loss, damage and cost
arising out of any breach of ProQuests representations or warranties under this Agreement. 11.3 Procedure.In the event it becomes aware of a claim for which indemnification may be
sought under this Article 11, the indemnified Party shall promptly notify the other in writing of
the claim. In case any proceeding (including any governmental investigation) shall be instituted
involving any Party in respect of which indemnity may be sought pursuant to this Article 11, such
Party (the Indemnified Party) shall promptly notify the other Party (the Indemnifying Party) in
writing and the Indemnifying Party and Indemnified Party shall meet to discuss how to respond to
any claims that are the subject matter of such proceeding. The Indemnifying Party, upon request of
the Indemnified Party, shall retain counsel reasonably satisfactory to the Indemnified Party to
represent the Indemnified Party and shall pay the fees and expenses of such counsel related to such
proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party
unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded
parties) include both the Indemnifying Party and the Indemnified Party and representation of both
parties by the same counsel would be inappropriate due to actual or potential differing interests
between them. All such fees and expenses shall be reimbursed as they are incurred. The
Indemnifying Party shall not be liable for any settlement of any proceeding effected without its
written consent, but if settled with such consent or if there be a final judgment for the
plaintiff, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any
loss or liability by reason of such settlement or judgment. The Indemnifying Party shall not,
without

##### 



the written consent of the Indemnified Party, effect any settlement of any pending or
threatened proceeding in respect of which the Indemnified Party is, or arising out of the same set
of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified
Party, unless such settlement includes an unconditional release of the Indemnified Party from all
liability on claims that are the subject matter of such proceeding. 11.4 Survival.The provisions of this Article 11 shall survive any termination of this
Agreement. ARTICLE 12. DISPUTE RESOLUTION 12.1 General.The Parties desire to establish the procedures in this Article 12 to
facilitate the resolution of any dispute pertaining to the rights and obligations of the Parties
under this Agreement in an expedient and commercially reasonable manner by mutual cooperation and
without resort to litigation. Except as otherwise provided in this Agreement or agreed by the
Parties in writing, all disputes under this Agreement will be resolved as set forth in this Article
12. 12.2 Initial Attempts to Resolve Disputes. (a) Any disputes between the Parties will first be addressed either informally between
the Parties or raised in the forum of the Governance Committee. If the matter is sufficiently
urgent, either Party may request a special meeting of the Governance Committee, in which event the
Parties will use Commercially Reasonable Efforts to convene such a special meeting at a time and
place that is mutually convenient to the Parties. If the Parties are unable to resolve a dispute
among them informally or in the Governance Committee, or the Governance Committee could not be
convened to consider the matter, during a period of thirty (30) days following the giving of formal
written notice by one Party to the other specifically invoking the dispute resolution procedure
contained in this Article 12, then either Party may, by written notice to the other, have such
dispute referred to their respective executive officers designated below or their successors, for
attempted resolution by good faith negotiations: For Guilford:Chief Executive Officer of Guilford For ProQuest:Chief Executive Officer of ProQuest In the event the designated executive officers are not able to resolve any such dispute within
thirty (30) days after written notice given by one Party to the other invoking this stage in the
dispute resolution procedure under this Article 12, either Party may by written notice to the other
commence the Arbitration process set forth in Section 12.3 below. (b) All negotiations pursuant to this Section 12.2 shall be treated as compromise and
settlement negotiations. Nothing said or disclosed, nor any document produced, in the course of
such negotiations which is not otherwise independently discoverable shall be offered or received as
evidence or used for impeachment or for any other purpose in any current or future arbitration or
litigation. 12.3 Arbitration.If a dispute has not been resolved by negotiation as provided in Section
12.2 above, then, except as otherwise provided in this Section 12.3, the dispute shall be
determined by arbitration in Chicago, Illinois in accordance with the Commercial Arbitration Rules
of the AAA, by three (3) arbitrators each of whom (i) has the qualifications and experience set
forth in subsection (a) of this Section 12.3 and (ii) is selected as provided in subsection (b) of
this Section 12.3. Any issue as to whether or the extent to which the dispute is subject to the
arbitration and other dispute resolution provisions contained in this Agreement, including, but not
limited to, issues relating to the validity or enforceability of these arbitration provisions, the
applicability of any statute of limitations or other defense relating to the timeliness of the
assertion of any claim or any other matter relating to the arbitrability of such claim, shall be
decided by the arbitrators; provided, however, that any person or entity who or which has not
agreed to be bound by the provisions of this Agreement or these arbitration provisions shall not be
bound by any

##### 



arbitration award rendered by the arbitrators unless such person or entity participates in the
arbitration proceeding and does not object to being bound by such award at or prior to the
commencement of the arbitration hearing. The arbitrators shall base their award on the terms of
this Agreement, and they shall endeavor to follow the law and judicial precedents which a U.S.
District Judge sitting in the Southern District of New York would apply in the event the dispute
were litigated in such court; provided, however, that nothing contained herein shall be deemed to
enlarge the grounds for vacating arbitral awards even if, despite such endeavors, the arbitrators
fail to correctly follow applicable law. The arbitrators shall render their award in writing and,
unless all Parties agree otherwise, shall include an explanation in reasonable detail of the
reasons for their award. The arbitration shall be governed by the substantive laws of the State of
New York and applicable to contracts made and to be performed therein, without regard to conflicts
of law rules, and by the arbitration law of the Federal Arbitration Act (Title 9, U.S. Code), and
judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction
thereof. The Parties expressly waive any putative right they may otherwise have to seek an award
of punitive damages arising out of any dispute hereunder. (a) Qualifications.Each person named on any list of potential arbitrators shall be either
(i) a neutral and impartial lawyer with excellent academic and professional credentials (x) who is
or has been practicing law at least fifteen (15) years, specializing in either general commercial
litigation or general corporate and commercial matters (or, if the dispute involves patent matters,
such as whether a product Developed and Commercialized by Guilford is an Agreement Compound or a
Program Product, then in patent law or litigation or judging relating to patents), with experience
in the field of the pharmaceutical/biotechnology industry and (y) who has had both training and
experience as an arbitrator and is generally available to serve as an arbitrator, or (ii) an
impartial and neutral retired U.S. federal court judge or an impartial and neutral retired judge
from the highest state court who (x) served as a judge for at least ten (10) years and (y) has had
both training and experience as an arbitrator and is generally available to serve as an arbitrator. (b) Selection.Each arbitrator shall be selected as provided in this Section 12.3 and
otherwise in accordance with the AAAs Commercial Arbitration Rules in effect on the Effective
Date. 12.4 Expenses.All expenses and fees of the arbitrators and expenses for hearing facilities
and other expenses of the arbitration shall be borne equally by Guilford and ProQuest unless the
Parties agree otherwise or unless the arbitrators in the award assess such expenses against one of
the Parties or allocate such expenses other than equally between Guilford and ProQuest. Each of
the Parties shall bear its own counsel fees and the expenses of its witnesses except (i) to the
extent otherwise provided in this Agreement or by applicable law or (ii) to the extent the
arbitrators in their discretion determine for any reason to allocate such fees and expenses among
the Parties in a different manner. Any attorney or retired judge who serves as an arbitrator shall
be compensated at a rate equal to his or her current regular hourly billing rate unless otherwise
mutually agreed upon by the Parties and the arbitrator. 12.5 Certain Terms.For purposes of this Article 12, the term impartial shall mean any
person who is not nor has been within the previous five (5) years an employee or paid consultant of
a Party, and does not have any other extended familial, close social, material ownership or other
relationship to a Party. 12.6 Arbitration Confidentiality.All aspects of an arbitration conducted pursuant to this
Agreement shall be and remain confidential and all participants shall be bound by judicially
enforceable obligations of strict confidentiality except to the extent (i) required by law,
including, without limitation, material disclosure requirements under applicable securities laws,
or (ii) the Parties agree in writing to waive in whole or part such confidentiality. 12.7 Survival.Any duty to arbitrate under this Agreement shall survive and remain in effect
and enforceable after termination of this Agreement for any reason.
