Confidential information shall consist of any information disclosed in writing, orally or in any other manner by a Party (the “Disclosing Party”) or otherwise made available to the other Party (the “Receiving Party”) concerning the Disclosing Party’s Intellectual Property Rights, know-how or performance of this Agreement or otherwise concerning the business, operations, trade secrets or other proprietary information of the Disclosing Party (“Confidential Information”). Except as otherwise provided herein, during the Term, and for [***] years thereafter, Archemix and SomaLogic shall not use or reveal or disclose to any Third Party any Confidential Information disclosed hereunder without first obtaining the written consent of the Disclosing Party. This confidentiality obligation shall not apply to such information:

(a) which is or becomes generally available to the public other than as a result of unauthorized disclosure thereof by the Receiving Party;

(b) which is lawfully received by the Receiving Party on a non-confidential basis from a Third Party that is not itself under any obligation of confidentiality or nondisclosure to the Disclosing Party or any other person with respect to such information;

(c) which by competent proof can be shown by the Receiving Party to have been independently developed by the Receiving Party; or

(d) which the Receiving Party establishes by competent proof was in its possession at the time of disclosure by the Disclosing Party and was not acquired, directly or indirectly from the Disclosing Party.

The Receiving Party shall use Confidential Information solely for the purposes of this Agreement and the transactions contemplated hereby and shall not disclose or disseminate any Confidential Information to any person at any time, except for disclosure to those of its directors, officers, employees, accountants, attorneys, advisers and agents whose duties reasonably require them to have access to such Confidential Information, provided that such directors, officers, employees, accountants, attorneys, advisers and agents are required to maintain the confidentiality of such Confidential Information to the same extent as if they were parties hereto. Each Receiving Party shall safeguard the Disclosing Party’s Confidential Information using at least the same degree of care, (but never less than a reasonable degree of care) that it uses to protect its own confidential or proprietary information.

4.2 Required Disclosures. All Confidential Information disclosed by the Disclosing Party to the Receiving Party shall remain the property of the Disclosing Party. The foregoing confidentiality and nondisclosure obligations shall not apply to information which is required to be publicly disclosed by law or by regulation; provided, however, that, in such event, the Receiving Party who is compelled to disclose such Confidential Information shall promptly notify, with a copy to the Disclosing Party, the court or other tribunal: (i) that Confidential Information received from the Disclosing Party under this Agreement remains the property of the Disclosing Party and (ii) of the confidentiality obligations under this Agreement. In addition, the

Receiving Party who is compelled to disclose the Confidential Information shall, to the extent permitted by law, take all steps necessary or desirable to maintain the confidentiality of the Disclosing Party’s Confidential Information and to insure that the court, other tribunal or appointee maintains such information in confidence in accordance with the terms of this Agreement.

4.3 Press Release. Immediately following the Parties’ execution of this Agreement, the Parties shall disclose the nature of this Agreement in a joint press release and each Party shall publish such press release on the Party’s web site for a period of at lease six (6) months; provided, however, that the Parties shall obtain each other’s prior consent on the text of such press release, such consent not to be unreasonably withheld or delayed. In the event that either Party reasonably determines that it is required by the applicable laws of any jurisdiction, or the rules of any stock exchange on which its securities are listed or traded, to publicly disclose information concerning this Agreement or the rights and obligations of the Parties hereunder, including without limitation, the circumstances under which money or other consideration may become payable hereunder and the amount(s) of such payment(s), then such Party shall provide the other Party with a reasonable opportunity to review the text of such disclosure and the disclosing Party shall use reasonable efforts to implement the reasonable comments provided by the other Party while still complying with such laws or rules.

SECTION 5
FILING, PROSECUTION AND MAINTENANCE OF PATENT RIGHTS

5.1 Patent Coordinators. Archemix and SomaLogic shall each appoint a patent coordinator (the “Patent Coordinators”), reasonably acceptable to the other Party, who shall serve as such Party’s primary liaison with the other Party on matters relating to filing, prosecution, maintenance and enforcement of the Licensed Patents. Each Party may replace its Patent Coordinator at any time by notice in writing to the other Party. The initial Patent Coordinators shall be:


		For Archemix:		John A. Harre

		For SomaLogic:		Randee S. Schwartz

5.2 Licensed Aptamers. The Parties, acting through the Patent Coordinators, shall be jointly responsible for preparing, filing, prosecuting, obtaining and maintaining, including opposition and nullity actions (collectively, “Procuring”) Patent Rights covering the Aptamer sequences licensed to Archemix pursuant to Section 2.2.1.2 herein. Archemix shall be solely responsible for all costs and fees associated with such efforts. Archemix shall be solely responsible for Procuring all other Patent Rights related to the Licensed Aptamers including, without limitation, methods of use, formulations, and methods of manufacture.

SECTION 6
ENFORCEMENT AND DEFENSE

6.1 Infringement of Licensed Patents. Each Party shall act in good faith to inform the other of any infringement of any of the Archemix Licensed Patents and/or SomaLogic

Licensed Patents within each of the Parties’ licensed fields by any Third Party of which it becomes aware. Subject to Section 6.2, each Party shall have the right (but not the obligation), at its own expense, to bring suit (or take other appropriate legal action) against any actual, alleged or threatened infringement of its rights under the Licensed Patents by a Third Party, with legal counsel of its own choice. Prior to bringing suit (or taking other appropriate legal action), notice will be provided to the other Party and the Parties will have an opportunity to confer regarding the suit. Any damages, monetary awards or other amounts recovered, whether by judgment or settlement, pursuant to any suit, proceeding or other legal action taken by a single Party under this Section shall belong solely to the Party bringing such action.

In the event the Parties mutually agree that the activities of a Third Party constitute an actual, alleged or threatened infringement of both Parties’ rights under the Licensed Patents, subject to any restrictions contained within Third Party Agreements, the Parties, acting through the Patent Coordinators, shall jointly determine whether to bring suit (or take other appropriate legal action) against the actual, alleged or threatened infringement. If both Parties desire to take such action, they shall jointly determine how to share the expense and proceeds, if any, of the action and they shall jointly choose legal counsel. If the Parties can not agree on how to jointly proceed, then each Party shall have the right (but not the obligation), at its own expense, to bring suit (or take other appropriate legal action) against any actual, alleged or threatened infringement of its rights under the Licensed Patents by a Third Party, with legal counsel of its own choice. If either Party declines to take any such action, the other Party shall have the right (but not the obligation), at its own expense, to bring suit (or take other appropriate legal action) against any actual, alleged or threatened infringement of its rights under the Licensed Patents by a Third Party, with legal counsel of its own choice. In either case, any damages, monetary awards or other amounts recovered, whether by judgment or settlement, pursuant to any suit, proceeding or other legal action taken by a single Party under this Section shall belong solely to the Party bringing such action.

If a Party brings any such action or proceeding hereunder, the other Party agrees to be joined as party plaintiff if necessary to prosecute such action or proceeding, and to give the Party bringing such action or proceeding reasonable assistance and authority to file and prosecute the suit at the expense of the Party bringing such action; provided, however, that neither Party shall be required to transfer any right, title or interest in or to any property to the other Party or any Third Party to confer standing on a Party hereunder.

6.2 Licensed Aptamers. In the event that any infringement relates to any Patent Rights covering Licensed Aptamers, Archemix shall have the sole right but not the obligation to enforce such Patent Rights.

6.3 Defense of Claims. Subject to any restrictions contained within any Third Party Agreements, in the event of the initiation of any suit by a Third Party Licensor against a Party hereunder for patent infringement arising out of such Party’s exercise of the license granted herein to the extent covered by a Third Party Agreement, such Party shall promptly notify the other Party in writing. The costs, expenses and responsibility for the defense of such suit shall be solely on the Party (or Parties) named in the suit unless otherwise agreed to by the Parties.

6.4 Warranty Disclaimer. NEITHER PARTY MAKES ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, OTHER THAN THOSE EXPRESSLY SET FORTH IN SECTION 9 BELOW, WITH RESPECT TO THE LICENSED PATENTS OR PRODUCTS, INCLUDING ANY WARRANTY OF NONINFRINGEMENT, PATENTABILITY, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

SECTION 7
TERM AND TERMINATION

7.1 Term. This Agreement shall commence upon the Restatement Effective Date and shall remain in effect until the expiration of the last to expire of the Archemix Licensed Patents, Archemix Patents, Other Archemix Patent Rights, SomaLogic Licensed Patents, SomaLogic Patents, and/or Other SomaLogic Patent Rights unless it is earlier terminated in accordance with this Section 7 (the “Term”).

7.2 Termination for Material Breach. Failure by a Party (the “Breaching Party”) to comply with any of its material obligations contained herein (a “Default”) shall entitle the Party that is not in Default (the “Terminating Party”), subject to the notice, cure and dispute resolution provisions set forth or referenced in this Section 7.2, to either: (i) terminate this Agreement in its entirety as provided in Section 7.3.1 or (ii) terminate the rights, licenses and options granted hereunder to the Party in Default as provided for in Section 7.3.2. Upon a Default, the Terminating Party shall give notice to the Breaching Party specifying the nature of the Default, demanding that it cure such Default, and stating its intention to terminate this Agreement if such Default is not cured. If such Default is not cured, or action undertaken that will cure such Default within [***] days after the receipt of such notice, then the Terminating Party shall be entitled, without prejudice to any other rights conferred on it by this Agreement, and in addition to any other remedies available to it by law or in equity, to terminate this Agreement; provided, however, that any right to terminate this Agreement shall be stayed in the event that, during such [***] day period, the Breaching Party shall have initiated dispute resolution in accordance with Section 10.6 hereof with respect to the alleged Default.

7.3 Consequences of Termination.

7.3.1 Termination of this Agreement. Upon Default of this Agreement, subject to Section 7.2 above, the Terminating Party may choose to terminate this Agreement in its entirety. Upon such a termination, all rights and licenses conferred or granted hereunder shall terminate, subject to those obligations which survive termination as set forth in Section 7.7.

7.3.2 Partial Termination. Upon Default of this Agreement, subject to Section 7.2 above, the Terminating Party may choose to terminate this Agreement in part as set forth herein. Upon such a partial termination, all rights, licenses and options granted to the Breaching Party hereunder shall terminate and the Agreement shall, in all other respects (including without limitation, the Terminating Party’s obligation to make payments hereunder if any) continue in full force and effect in accordance with its terms.

7.4 Termination by Mutual Agreement. At any time, the Parties may agree in writing to terminate this Agreement, which termination shall be effective as of the date agreed upon by the Parties.

7.5 Termination Upon Insolvency. This Agreement may be terminated by either Party upon notice to the other Party should such other Party: (i) consent to the appointment of a receiver or a general assignment for the benefit of creditors, or (ii) file or consent to the filing of a petition under any bankruptcy or insolvency law or have any such petition filed against it which has not been stayed within [***] days of such filing.

7.6 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code.

7.7 Unilateral Right to Terminate. If the Restatement Effective Date does not occur on or before [***] business days from the Restatement Execution Date, either Party may terminate this Agreement immediately upon written notice to the other Party.

7.8 Accrued Rights; Surviving Obligations. Termination of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of a Party prior to or on account of such termination. All remedies provided hereunder or elsewhere are cumulative. Sections 2.8.2, 2.16.2, 3.6, 3.9, 4, 7.3, 7.8, 8, 9.1(d), 10.4, 10.5, 10.6, 10.10, 10.13, and 10.14 of this Agreement shall survive the termination of this Agreement for any reason and, Section 1 hereof shall survive such termination to the extent any terms defined therein are used in such other surviving provisions.

SECTION 8
INSURANCE; INDEMNITY

8.1 Insurance. Each Party shall maintain in full force and effect general liability insurance coverage, with terms comparable to those maintained by other similarly-situated biomedical companies engaged in similar activities, during the Term and for an additional period of [***] years thereafter. The amounts of insurance coverage required under this Section 8.1 shall not be construed to create a limit of the other Party’s liability with respect to its indemnification obligation under Section 8 or under any other provision of this Agreement.

8.2 Indemnification. Subject to Section 8.3 below, from and after the Restatement Effective Date, except as otherwise herein specifically provided, each of the Parties hereto shall defend, indemnify and hold harmless the other Party and its successors and assigns, and their respective officers, directors, shareholders, partners and employees from and against all losses, damage, liability and expense including legal fees (but excluding punitive or consequential damages (including lost profits)) (“Losses”) incurred thereby or caused thereto arising out of or relating to (i) any breach or violation of, or failure to properly perform, any covenant or agreement made by such Indemnifying Party (as defined in Section 8.3) in this Agreement, unless waived in writing by the Indemnified Party (as defined in Section 8.3); (ii) any breach of any of the representations or warranties made by such Indemnifying Party in this Agreement;

(iii) the gross negligence or willful misconduct of the Indemnifying Party and (iv) product liability arising out of the manufacture, use, sale or importation of any product by the Indemnifying Party or an Affiliate or sublicensee of such Indemnifying Party.

8.3 Indemnification Procedure. If either Archemix or SomaLogic (in each case an “Indemnified Party”) receives any written claim which it believes is the subject of indemnity hereunder by the other Party (in each case an “Indemnifying Party”) the Indemnified Party shall, as soon as reasonably practicable after forming such belief, give notice thereof to the Indemnifying Party, including full particulars of such claim to the extent known to the Indemnified Party; provided, however, that the failure to give timely notice to the Indemnifying Party as contemplated hereby shall not release the Indemnifying Party from any liability to the Indemnified Party except to the extent the Indemnifying Party can demonstrate that such failure materially prejudiced the rights of the Indemnifying Party. The Indemnifying Party shall have the right, by prompt notice to the Indemnified Party, to assume the defense of such claim with counsel reasonably satisfactory to the Indemnified Party, and at the cost of the Indemnifying Party. If the Indemnifying Party does not so assume the defense of such claim, the Indemnified Party may assume such defense with counsel of its choice at the sole expense of the Indemnifying Party. If the Indemnifying Party so assumes such defense, the Indemnified Party may participate therein through counsel of its choice, but the cost of such counsel shall be borne solely by the Indemnified Party.

8.4 Assistance. The Party not assuming the defense of any such claim shall render all reasonable assistance to the Party assuming such defense, and all out-of-pocket costs of such assistance shall be borne solely by the Indemnifying Party.

8.5 Settlement. No such claim shall be settled other than by the Party defending the same, and then only with the consent of the other Party, which shall not be unreasonably withheld; provided, however, that the Indemnified Party shall have no obligation to consent to any settlement of any such claim which imposes on the Indemnified Party any liability or obligation which cannot be assumed and performed in full by the Indemnifying Party.

8.6 Limitation on Losses. IN NO EVENT SHALL ANY PARTY OR ANY OF THEIR AFFILIATES BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY OTHER PARTY, WHETHER IN CONTRACT, WARRANTY, NEGLIGENCE, TORT, STRICT LIABILITY OR OTHERWISE, ARISING OUT OF (A) THE MANUFACTURE, USE OR SALE OF ANY PRODUCT DEVELOPED OR MARKETED HEREUNDER OR (B) ANY BREACH OF OR FAILURE TO PERFORM ANY OF THE PROVISIONS OF THIS AGREEMENT EXCEPT TO THE EXTENT REQUIRED FOR AN INDEMNIFYING PARTY TO PROVIDE INDEMNITY TO AN INDEMNIFIED PARTY AGAINST SUCH DAMAGES PURSUANT TO SECTION 8.3 IN THE EVENT SUCH DAMAGES ARE SUCCESSFULLY ASSERTED AGAINST AN INDEMNIFIED PARTY BY A THIRD PARTY.

SECTION 9

SECTION 10
MISCELLANEOUS

10.1 Force Majeure. If the performance of any part of this Agreement by either Party, or of any obligation under this Agreement, is prevented, restricted, interfered with or delayed by reason of any cause beyond the control of the Party liable to perform (a “Force Majeure Event”), unless conclusive evidence to the contrary is provided, the Party so affected shall give written notice to the other Party within [***] days after the occurrence of such Force Majeure Event and, upon giving written notice to the other Party, be excused from such performance to the extent of such prevention, restriction, interference or delay, provided that the affected Party shall use its reasonable best efforts to avoid or remove such causes of nonperformance and shall continue performance with the utmost dispatch whenever such causes are removed. When such circumstances arise, the Parties shall discuss what, if any, modification of the terms of this Agreement may be required in order to arrive at an equitable solution. Force Majeure Events shall include, without limitation, war, revolution, invasion, insurrection, riots, mob violence, labor strikes, sabotage or other civil disorders, acts of God, or limitations imposed by laws, regulations or rules of any government or governmental agency.

10.3 Severability. In the event any provision of this Agreement shall be held illegal, void, or ineffective, then the Parties shall promptly negotiate in good faith a lawful, valid and enforceable provision that is as similar to the invalid provision as may be possible, in order to maintain the benefits and burdens accruing to the Parties hereunder, and the remaining portions hereof shall remain in full force and effect. In the event that the Parties cannot agree on a provision to replace such invalid provision, and the provision is material to a Party’s overall benefits and burdens hereunder, then the Parties shall attempt, in good faith, to amend this

Agreement to maintain the overall balance of benefits and burdens between the Parties as set forth herein.

10.4 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to the rules of conflict of laws thereof.

Exhibit 10.6(b)

Dispute Resolution for Disputes under Section 10.6(b)

A. Any arbitration commenced pursuant to Section 10.6(b) above will be conducted in accordance with the following rules:

(1) In the event that either Party (the “Complaining Party”) notifies the other (the “Defending Party”) in writing that it believes that the Defending Party is acting in violation of this Agreement, and in that notification states with reasonable particularity the nature of such alleged violation, the Parties will then cooperate in an expedited arbitration proceeding in which the merits of such allegation are determined.

(2) Immediately upon receipt of the above-mentioned notification, the Parties will confer and seek to agree upon a single arbitrator who is available to hear and decide the merits of the alleged violation within the time frame set forth herein. If such agreement is not reached within [***] days of said notification, the Parties will, on the first business day following, the expiration of such [***] days, jointly request in writing, sent immediately by facsimile, that the Chicago, Illinois office of the American Arbitration Association (“AAA“) select an arbitrator within [***] days who the AAA believes, in its sole discretion, is qualified and sufficiently available to decide the matters in issue and to do so within the time frame set forth herein. If either Party fails to join in such joint request the other Party shall have the right to make such request on behalf of both Parties.

(3) Within [***] days following the designation of the arbitrator, the Complaining Party shall serve, by immediate facsimile, upon the Defending Party and the arbitrator, its factual and legal submission, together with all documents it wishes to be considered by the arbitrator, in support of its claim that the Defending Party is acting in violation of this Agreement.

(4) Within [***] days following the service of the submission referred to in sub-subsection (3) above, the Defending Party shall serve, by immediate facsimile, upon the Complaining Party, its factual and legal submission together with all documents it wishes to be considered by the arbitrator, in opposition to the Complaining Party’s allegations.

(5) Within [***] days after service of the Defending Party’s submission, either Party may request from the other Party any specifical1y identified document in the other Party’s possession which the requesting Party believes is relevant and important for the arbitrator to consider in deciding the case. Within [***] days after receiving such request, the other Party shall either provide the requested documents or notify the requesting Party and arbitrator that it opposes the request or some part thereof, in which case the arbitrator shall hold

a conference call with the Parties within [***] days, hear the Parties’ arguments, and decide and provide the Parties with a copy of a written decision, under the general principles followed in AAA proceedings, within [***] days, what documents must be provided. Within [***] days after such decision by the arbitrator, all documents required to be produced shall be delivered to the requesting Party. In the event of a Party’s failure to make timely production of documents pursuant to the arbitrator’s ruling, the arbitrator shall have discretion to disallow or limit the claim or defense of that Party.

(6) Within [***] days after production of all documents by the Parties as provided for herein, the arbitrator shall request, by facsimile to the Parties, any further factual or legal information from the Parties he/she believes to be necessary to decide the matters in issue. The Parties shall provide such information to the arbitrator and to each other within [***] days of said request.

(7) Within [***] days after the completion of document production, the arbitrator shall hold a hearing at a location of the arbitrator’s choosing in Chicago. The length of such hearing, the number of witnesses, the number of documents to be considered, and all other aspects of such hearing shall be determined by the arbitrator such that such hearing does not last for more than ten (10) days, including weekends.

(8) Within [***] days after the close of the hearing, either Party may submit to the arbitrator, with service upon the other, further written arguments based upon evidence heard at the hearing.

(9) Within [***] days after the close of the hearing, the arbitrator shall render her/his written decision, sent by facsimile to the Parties, on all issues submitted for decision. The arbitrator shall state briefly the facts and reasons for such decision.

(10) Within [***] days after receiving the decision, either Party may submit a request to the arbitrator, with service by facsimile on the other Party, for reconsideration of the decision, setting forth all factual and legal arguments in support of such request. Within [***] days thereafter, the other Party may submit to the arbitrator, with service by facsimile on the other Party, an opposition or other response to the request.

(11) Within [***] days after receipt of any such requests for reconsideration and responses thereto, the arbitrator shall render her/his decision as to such request and a final ruling on the merits of all claims heard in the arbitration. This decision will be final and binding upon the Parties as to all issues decided in the arbitration, subject only to judicial review under the Federal Arbitration Act.

(12) The Parties shall pay promptly and in equal shares all expenses of the arbitration as assessed by the arbitrator and/or the AAA.

(13) In addition to the specific powers and responsibilities set forth herein, the arbitrator shall have all powers and discretion customarily exercised in arbitrations under the Commercial Rules of the AAA.

B. If either Party hereto wishes to have an interpretation as to whether a particular action or proposed action would violate this Agreement, such Party may commence an arbitration to determine whether such action would constitute a violation. Any arbitration commenced pursuant to this section B will be conducted in accordance with the following rules:

(1) In the event a Complaining Party wishes to obtain a declaratory ruling in arbitration as to whether a particular action or proposed action would violate this Agreement, the Complaining Party shall notify the Defending Party and in that notification state with reasonable particularity the nature of the issue raised and the declaratory ruling sought, and the Parties will then cooperate in an expedited arbitration proceeding in which the merits of such declaratory relief are determined.

(2) Immediately upon receipt of the above-mentioned notification, the Parties will confer and seek to agree upon a single arbitrator who is available to hear and decide the merits of the declaratory relief requested within the time frame set forth herein. If such agreement is not reached within [***] days after said notification, the Parties will, on the first business day following the expiration of such [***] days, jointly request in writing, sent immediately by facsimile, that the Chicago office of the AAA select an arbitrator within [***] days who the AAA believes, in its sole discretion, is qualified and sufficiently available to decide the matters in issue and to do so within the time frame set forth herein. If either Party fails to join in such joint request, the other Party shall have the right to make such request on behalf of both Parties.

(5) Within [***] days after the service of the Defending Party’s submission, the arbitrator shall hold a hearing at a location of the arbitrator’s choosing in Chicago. The length of such hearing, the number of witnesses, the number of documents to be considered, and all other aspects of such hearing shall be determined by the arbitrator such that such hearing does not last for more than ten (10) days, including weekends.

(6) Within [***] days after the close of the hearing, either Party may submit to the arbitrator, with service upon the other, further written arguments based upon evidence heard at the hearing.

(7) Within [***] days after the close of the hearing, the arbitrator shall render her/his written decision, sent by facsimile to the Parties, on all issues submitted for decision. The arbitrator shall state briefly the facts and reasons for such decision.

(8) Within [***] days after receiving the decision, either Party may submit a request to the arbitrator, with service by facsimile on the other Party, for reconsideration of the decision, setting forth all factual and legal arguments in support of such request. Within [***] days thereafter, the other Party may submit to the arbitrator, with service by facsimile on the other Party, an opposition or other response to the request.

(9) Within [***] days after receipt of any such requests for reconsideration and responses thereto, the arbitrator shall render her/his decision as to such request and a final ruling on the merits of all claims heard in the arbitration. This decision will be final and binding upon the Parties as to all issues decided in the arbitration, subject only to judicial review under the Federal Arbitration Act.

(10) The Parties shall pay promptly and in equal shares all expenses of the arbitration as assessed by the arbitrator and/or the AAA.

(11) In addition to the specific powers and responsibilities set forth herein, the arbitrator shall have all powers and discretion customarily exercised in arbitrations under the Commercial Rules of the AAA.
