Unconditional Guaranty


 Exhibit 10.3 
 UNCONDITIONAL GUARANTY 
 For and in consideration of the loan by COMERICA BANK (“Bank”) to
TPTX, INC. (“Borrower”), which loan is made pursuant to a Loan and Security Agreement between Borrower and Bank dated as of June 11, 2008, as amended from time to time (the “Agreement”), and acknowledging that Bank would not
enter into the Agreement without the benefit of this Guaranty, the undersigned guarantor (“Guarantor”) hereby unconditionally and irrevocably guarantees the prompt and complete payment of all amounts that Borrower owes to Bank and
performance by Borrower of the Agreement and any other agreements between Borrower and Bank, as amended from time to time (collectively referred to as the “Agreements”), in strict accordance with their respective terms. All terms used
without definition in this Guaranty shall have the meaning assigned to them in the Agreement. 
 1. If Borrower does not pay any amount or
perform its obligations in strict accordance with the Agreements, Guarantor shall immediately pay all amounts due thereunder (including, without limitation, all principal, interest, and fees) and otherwise to proceed to complete the same and satisfy
all of Borrower’s obligations under the Agreements. 
 2. If there is more than one guarantor, the obligations hereunder are joint and
several, and whether or not there is more than one guarantor, the obligations hereunder are independent of the obligations of Borrower and any other person or entity, and a separate action or actions may be brought and prosecuted against Guarantor
whether action is brought against Borrower or whether Borrower be joined in any such action or actions. Guarantor waives the benefit of any statute of limitations affecting its liability hereunder or the enforcement thereof, to the extent permitted
by law. Guarantor’s liability under this Guaranty is not conditioned or contingent upon the genuineness, validity, regularity or enforceability of the Agreements. 
 3. Guarantor authorizes Bank, without notice or demand and without affecting its liability hereunder, from time to time to (a) renew, extend, or otherwise change the terms of the Agreements or any part thereof;
(b) take and hold security for the payment of this Guaranty or the Agreements, and exchange, enforce, waive and release any such security; and (c) apply such security and direct the order or manner of sale thereof as Bank in its sole
discretion may determine. 
 4. Guarantor waives any right to require Bank to (a) proceed against Borrower, any guarantor or any other
person; (b) proceed against or exhaust any security held from Borrower; or (c) pursue any other remedy in Bank’s power whatsoever. Bank may, at its election, exercise or decline or fail to exercise any right or remedy it may have
against Borrower or any security held by Bank, including without limitation the right to foreclose upon any such security by judicial or nonjudicial sale, without affecting or impairing in any way the liability of Guarantor hereunder. Guarantor
waives any defense arising by reason of any disability or other defense of Borrower or by reason of the cessation from any cause whatsoever of the liability of Borrower. Guarantor waives any setoff, defense or counterclaim that Borrower may have
against Bank. Guarantor waives any defense arising out of the absence, impairment or loss of any right of reimbursement or subrogation or any other rights against Borrower. Until all of the amounts that Borrower owes to Bank have been paid in full,
Guarantor shall have no right of subrogation or reimbursement, contribution or other rights against Borrower, and Guarantor waives any right to enforce any remedy that Bank now has or may hereafter have against Borrower. Guarantor waives all
presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor, and notices of acceptance of this Guaranty and of the existence, creation, or incurring of new or additional indebtedness. Guarantor
assumes the responsibility for being and keeping itself informed of the financial condition of Borrower and of all other circumstances bearing upon the risk of nonpayment of any indebtedness or nonperformance of any obligation of Borrower, warrants
to Bank that it will keep so informed, and agrees that absent a request for particular information by Guarantor, Bank shall not have any duty to advise Guarantor of information known to Bank regarding such condition or any such circumstances.
Guarantor waives the benefits of California Civil Code sections 2809, 2810, 2819, 2845, 2847, 2848, 2849, 2850, 2899 and 3433. 
 5.
Guarantor acknowledges that, to the extent Guarantor has or may have certain rights of subrogation or reimbursement against Borrower for claims arising out of this Guaranty, those rights may be impaired or destroyed if Bank elects to proceed against
any real property security of Borrower by non-judicial foreclosure. That impairment or destruction could, under certain judicial cases and based on equitable principles of estoppel, give rise to a defense by Guarantor against its obligations under
this Guaranty. Guarantor 

  

 1 







 
waives that defense and any others arising from Bank’s election to pursue non-judicial foreclosure. Without limiting the generality of the foregoing,
Guarantor waives any and all benefits and defenses under California Code of Civil Procedure Sections 580a, 580b, 580d and 726, to the extent they are applicable. 
 Guarantor waives all rights and defenses arising out of an election of remedies by Bank even though that election of remedies, such as a nonjudicial foreclosure with respect to security for a guaranteed obligation,
has destroyed the Guarantor’s rights of subrogation and reimbursement against Borrower by the operation of Section 580d of the Code of Civil Procedure or otherwise. 
 Without limiting the generality of any other waiver or other provision set forth in this Guaranty, each undersigned Guarantor waives all rights and
defenses that any such undersigned Guarantor may have because the Indebtedness is secured by real property. This means, among other things: 
 (1) Bank may collect from any undersigned Guarantor without first foreclosing on any real or personal property collateral pledged by any Borrower to secure the Indebtedness. 
 (2) If Bank forecloses on any real property collateral pledged by any Borrower to secure the Indebtedness: 
 (a) the amount of the Indebtedness may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the
collateral is worth more than the sale price. 
 (b) Bank may collect from any undersigned Guarantor even if Bank, by
foreclosing on the real property pledged as collateral, has destroyed any right that the undersigned Guarantor may have to collect from Borrower. 
 This is an unconditional and irrevocable waiver of any rights and defenses each undersigned Guarantor may have because the Indebtedness is secured by Real Property. These rights and defenses include, but are not limited to, any rights or
defenses based upon Section 580a, 580b, 580d, or 726 of the California Code of Civil Procedure. 
 6. If Borrower becomes insolvent or
is adjudicated bankrupt or files a petition for reorganization, arrangement, composition or similar relief under any present or future provision of the United States Bankruptcy Code, or if such a petition is filed against Borrower, and in any such
proceeding some or all of any indebtedness or obligations under the Agreements are terminated or rejected or any obligation of Borrower is modified or abrogated, or if Borrower’s obligations are otherwise avoided for any reason, Guarantor
agrees that Guarantor’s liability hereunder shall not thereby be affected or modified and such liability shall continue in full force and effect as if no such action or proceeding had occurred. This Guaranty shall continue to be effective or be
reinstated, as the case may be, if any payment must be returned by Bank upon the insolvency, bankruptcy or reorganization of Borrower, Guarantor, any other guarantor, or otherwise, as though such payment had not been made. 
 7. Any indebtedness of Borrower now or hereafter held by Guarantor is hereby subordinated to any indebtedness of Borrower to Bank; and such indebtedness
of Borrower to Guarantor shall be collected, enforced and received by Guarantor as trustee for Bank and be paid over to Bank on account of the indebtedness of Borrower to Bank but without reducing or affecting in any manner the liability of
Guarantor under the other provisions of this Guaranty. 
 8. Guarantor agrees to pay reasonable attorneys’ fees and all other costs and
expenses which may be incurred by Bank in the enforcement of this Guaranty. No terms or provisions of this Guaranty may be changed, waived, revoked or amended without the prior written consent of Bank and Guarantor. Should any provision of this
Guaranty be determined by a court of competent jurisdiction to be unenforceable, all of the other provisions shall remain effective. This Guaranty, together with any agreements (including without limitation any security agreements or any pledge
agreements) executed in connection with this Guaranty, embodies the entire agreement among the parties hereto with respect to the matters set forth herein, and supersedes all prior agreements among the parties with respect to the matters set forth
herein. No course of prior dealing among the parties, no usage of 

  

 2 







 
trade, and no parol or extrinsic evidence of any nature shall be used to supplement, modify or vary any of the terms hereof. There are no conditions to the
full effectiveness of this Guaranty. Bank may assign this Guaranty without in any way affecting Guarantor’s liability under it. This Guaranty shall inure to the benefit of Bank and its successors and assigns. This Guaranty is in addition to the
guaranties of any other guarantors and any and all other guaranties of Borrower’s indebtedness or liabilities to Bank. 
 9. Guarantor
represents and warrants to Bank that (i) Guarantor has taken all necessary and appropriate action to authorize the execution, delivery and performance of this Guaranty, (ii) execution, delivery and performance of this Guaranty do not
conflict with or result in a breach of or constitute a default under Guarantor’s Certificate of Incorporation or Bylaws or other organizational documents or agreements to which it is party or by which it is bound, and (iii) this Guaranty
constitutes a valid and binding obligation, enforceable against Guarantor in accordance with its terms. 
 10. Guarantor covenants and agrees
that Guarantor shall do all of the following: 
 10.1 Guarantor shall maintain its corporate existence, remain in good
standing in Delaware, and continue to qualify in each jurisdiction in which the failure to so qualify could have a material adverse effect on the financial condition, operations or business of Guarantor. Guarantor shall maintain in force all
licenses, approvals and agreements, the loss of which could have a material adverse effect on its financial condition, operations or business. 
 10.2 Guarantor shall comply with all statutes, laws, ordinances, directives, orders, and government rules and regulations to which it is subject if non-compliance with such laws could adversely affect the financial
condition, operations or business of Guarantor. 
 10.3 At any time and from time to time Guarantor shall execute and deliver
such further instruments and take such further action as may reasonably be requested by Bank to effect the purposes of this Guaranty. 
 10.4 Guarantor shall not transfer, assign, encumber or otherwise dispose of any shares of capital stock or other equity interest Guarantor may now have or hereafter acquire in Borrower. 
 11. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER. 
 This Guaranty shall be governed by, and construed in accordance with, the internal laws of the State of California, without regard to principles of conflicts of law. Each of Borrower and Bank hereby submits to the
exclusive jurisdiction of the state and Federal courts located in the County of Santa Clara, State of California. THE UNDERSIGNED ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN
CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO
TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS GUARANTY OR ANY OTHER DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN THE UNDERSIGNED PARTIES. 
 12. REFERENCE PROVISION. 
 In the event the Jury Trial Waiver set forth above is not
enforceable, the parties elect to proceed under this Judicial Reference Provision. 
 12.1 Mechanics. 
 (a) With the exception of the items specified in clause (c), below, any controversy, dispute or claim (each, a “Claim”) between
the parties arising out of or relating to this Agreement or any other document, instrument or agreement between the undersigned parties (collectively in this Section, the “Comerica Documents”), will be resolved by a reference 

  

 3 







 
proceeding in California in accordance with the provisions of Sections 638 et seq. of the California Code of Civil Procedure (“CCP”), or their
successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Comerica Documents, venue for the reference
proceeding will be in the state or federal court in the county or district where the real property involved in the action, if any, is located or in the state or federal court in the county or district where venue is otherwise appropriate under
applicable law (the “Court”). 
 (b) The matters that shall not be subject to a reference are the following:
(i) nonjudicial foreclosure of any security interests in real or personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary, provisional or
ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). This reference provision does not limit the right of any party to exercise or oppose any of the
rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does not
waive the right of any party to a reference pursuant to this reference provision as provided herein. 
 (c) The referee shall
be a retired judge or justice selected by mutual written agreement of the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by
the Presiding Judge of the Court (or his or her representative). A request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted.
Pursuant to CCP § 170.6, each party shall have one peremptory challenge to the referee selected by the Presiding Judge of the Court (or his or her representative). 
 (d) The parties agree that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested,
subject to change in the time periods specified herein for good cause shown, to (i) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection of the referee, (ii) if practicable, try
all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement of decision within twenty (20) days after the matter has been submitted for decision. 
 (e) The referee will have power to expand or limit the amount and duration of discovery. The referee may set or extend discovery deadlines
or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered based upon good cause shown, no party shall be entitled to “priority” in conducting discovery,
depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All disputes relating to discovery which cannot be resolved by the parties
shall be submitted to the referee whose decision shall be final and binding. 
 12.2 Procedures. Except as expressly
set forth herein, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of
the reference proceeding. All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before
the referee, and the referee will be provided a courtesy copy of the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs to the
prevailing party, the parties will equally share the cost of the referee and the court reporter at trial. 
 12.3
Application of Law. The referee shall be required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of
California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a
court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the
reference. Pursuant to CCP § 644, 

  

 4 







 
such decision shall be entered by the Court as a judgment or an order in the same manner as if the action had been tried by the Court and any such decision
will be final, binding and conclusive. The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order entered by the referee. The parties reserve the right to findings of fact, conclusions of laws,
a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under this provision. 
 12.4 Repeal. If the enabling legislation which provides for appointment of a referee is repealed (and no successor statute is
enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge or justice, in accordance with the California
Arbitration Act §1280 through §1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding. 
 12.5 THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES, DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED
BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS REFERENCE
PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE OTHER COMERICA DOCUMENTS. 
 IN WITNESS WHEREOF, the undersigned Guarantor has executed this Guaranty as of June 11, 2008.
