any time and from time to time (whether or not after revocation or termination of this Guaranty), without incurring responsibility to Guarantor, and without impairing or releasing any of the obligations of Guarantor hereunder and, upon or without
any terms or conditions, and in whole or in part: (i) agree with ISCO to change the manner, place or terms of performance, including (without limitation) any change or extend the time of performance of, renew or alter, any of the Obligations,

any security nor any other dealing (or failure to deal) with any security by Payees with respect to any of the Obligations, shall impair or release any of the obligations of Guarantor hereunder. No invalidity, irregularity or unenforceability of all
or any part of the Obligations or of any security therefor shall affect, impair or be a defense to this Guaranty, and this Guaranty is a primary obligation of Guarantor. 
 (d) Waiver of Subrogation. No payment by Guarantor except the indefeasible performance in full of the Obligations shall entitle Guarantor to be subrogated to any of the rights of Payees. Guarantor shall have no
right of reimbursement or indemnity whatsoever and no right of recourse to or with respect to any assets or property of ISCO or to any security for the Obligations, unless and until all of the Obligations have been indefeasibly performed in full,

 2 

 (e) Payment Guaranty; Waiver of Defenses, Counterclaims, Etc. Guarantor hereby agrees that this
Guaranty constitutes guaranty of payment, performance and compliance (and not a guaranty of collection only), and waives any right to require that any resort be had by Payees to ISCO or any other guarantor or to any security pledged with respect to
the performance of any of the Obligations. Further, this guaranty of payment is absolute and unconditional, and shall remain valid, binding and fully enforceable irrespective of any circumstance of any nature that might otherwise constitute a
defense, offset, claim, abatement or counterclaim that Guarantor or ISCO may assert against Payees with respect to any of the Obligations or otherwise, including, but not limited to, failure of consideration, fraudulent inducement, breach of
warranty, payment, statute of frauds, statute of limitations, accord and satisfaction, and usury, and irrespective of the validity, legality, binding effect or enforceability of the terms of any agreement or instrument relating to any of the
Obligations. Guarantor hereby absolutely, unconditionally and irrevocably waives any and all rights to assert any such defenses, offsets, claims, abatements and counterclaims. In the event Payees are not permitted or otherwise unable (because of the
pendency of any bankruptcy, insolvency, receivership or other similar proceeding) to accelerate the Obligations but would otherwise be permitted to do so at such time pursuant to the Loan Agreement, Payees may demand performance in full under this
Guaranty as if all of the Obligations had been duly accelerated, and Guarantor will not raise, and hereby expressly waives, any claim or defense with respect to such acceleration. 
 Section 3. Remedies. In the case of any proceedings to collect any obligations of Guarantor, Guarantor shall pay all costs and
expenses of every kind for collection and enforcement of this Guaranty, including attorneys’ fees and disbursements. Upon the occurrence and during the continuance of any failure of any of the Obligations to be performed when due, Payees may
elect to nonjudicially or judicially foreclose against any real or personal property security it holds for the Obligations, or accept an assignment of any such security in lieu of foreclosure or compromise or adjust any part of the Obligations, or
make any other accommodation with ISCO or any other guarantor, pledgor or surety, or exercise any other remedy against ISCO or any other guarantor, pledgor or surety, or any security, in accordance with and subject to the provisions of the documents
creating such security interests. No such action by Payees will release, limit or otherwise affect the obligations of Guarantor to Payees, even if the effect of that action is to deprive Guarantor of the right to collect any reimbursement from ISCO
or any other person for any sums paid to Payees. 
 Section 4. Reinstatement, Indemnification, Etc. If claim is ever made
upon Payees for repayment, return, restoration or other recovery of any amount or amounts received by Payees in payment or on account of any of the Obligations, and Payees repay all or part of such amount: (a) because such payment or
application of proceeds is or may be avoided, invalidated, declared fraudulent, set aside or determined to be void or voidable as a preferential transfer, fraudulent conveyance, impermissible set off or a diversion of trust funds; or (b) for
any other reason, including (without limitation) by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over Payees or any of their property, or (ii) any settlement or compromise of any such
claim effected by Payees with any such claimant (including ISCO); then, and in such event, Guarantor agrees that any such judgment, decree, 
  

 3 

 order, settlement or compromise shall be binding upon Guarantor, notwithstanding any revocation hereof or the
cancellation of any Notes or other instrument or document evidencing any of the Obligations and the obligations of Guarantor hereunder shall continue to apply, or shall automatically (and without further action) be reinstated if not then in effect,
as case may be, and Guarantor shall be and remain liable to Payees hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by Payees. Guarantor hereby indemnifies Payees, and agrees to
reimburse and hold Payees harmless on demand, from and against all actions, claims, losses, judgments, damages, amounts paid in settlement and expenses (including reasonable attorneys’ fees and court costs) brought against or incurred by Payees
and arising out of, relating to or in connection with any of the Obligations. 
 Section 5. Waiver of Rights, Etc. No
delay on the part of Payees in exercising any of their options, powers or rights, or partial or single exercise thereof, shall constitute a waiver thereof. No waiver of any of their rights hereunder, and no modification or amendment of this
Guaranty, shall be deemed to be made by Payees unless the same shall be in writing, duly signed by an officer of each Payee on behalf of such Payee, and each such waiver, if any, shall apply only with respect to the specific instance involved, and
shall in no way impair the rights of Payees or the obligations of Guarantor to Payees in any other respect at any other time. 
 Section 6. Enforcement, Etc. Payees, in their sole discretion, may proceed to exercise or enforce any right, power, privilege, remedy or interest that Payees may have under this Guaranty, the Obligations or any applicable
law: at law, in equity, in rem or in any other forum available under applicable law; without notice except as otherwise expressly required by law provided herein; without pursuing, exhausting or otherwise exercising or enforcing any other right,
power, privilege, remedy or interest that Payees may have against or in respect of Guarantor, the Obligations, ISCO, any other guarantor, surety, pledgor, collateral or any other person or thing; and without regard to any act or omission of Payees
or any other person. Each Payee may enforce this Guaranty individually as to its portion of the Obligations. 
 Section 7.
Reliance. Guarantor expressly acknowledges that Guarantor has not received or relied upon any oral or written agreements, understandings, representations or warranties from Payees or any other party with respect to this Guaranty (or
any of Guarantor’s obligations hereunder), and that this Guaranty contains the entire understanding of the parties with respect to the subject matter hereof and supersedes and replaces any and all prior oral or written agreements and

 2 

 (e) Payment Guaranty; Waiver of Defenses, Counterclaims, Etc. Guarantor hereby agrees that this
Guaranty constitutes guaranty of payment, performance and compliance (and not a guaranty of collection only), and waives any right to require that any resort be had by Payees to ISCO or any other guarantor or to any security pledged with respect to
the performance of any of the Obligations. Further, this guaranty of payment is absolute and unconditional, and shall remain valid, binding and fully enforceable irrespective of any circumstance of any nature that might otherwise constitute a
defense, offset, claim, abatement or counterclaim that Guarantor or ISCO may assert against Payees with respect to any of the Obligations or otherwise, including, but not limited to, failure of consideration, fraudulent inducement, breach of
warranty, payment, statute of frauds, statute of limitations, accord and satisfaction, and usury, and irrespective of the validity, legality, binding effect or enforceability of the terms of any agreement or instrument relating to any of the
Obligations. Guarantor hereby absolutely, unconditionally and irrevocably waives any and all rights to assert any such defenses, offsets, claims, abatements and counterclaims. In the event Payees are not permitted or otherwise unable (because of the

Guaranty as if all of the Obligations had been duly accelerated, and Guarantor will not raise, and hereby expressly waives, any claim or defense with respect to such acceleration.

make any other accommodation with ISCO or any other guarantor, pledgor or surety, or exercise any other remedy against ISCO or any other guarantor, pledgor or surety, or any security, in accordance with and subject to the provisions of the documents
creating such security interests. No such action by Payees will release, limit or otherwise affect the obligations of Guarantor to Payees, even if the effect of that action is to deprive Guarantor of the right to collect any reimbursement from ISCO
or any other person for any sums paid to Payees. 
 Section 4. Reinstatement, Indemnification, Etc. If claim is ever made
upon Payees for repayment, return, restoration or other recovery of any amount or amounts received by Payees in payment or on account of any of the Obligations, and Payees repay all or part of such amount: (a) because such payment or
application of proceeds is or may be avoided, invalidated, declared fraudulent, set aside or determined to be void or voidable as a preferential transfer, fraudulent conveyance, impermissible set off or a diversion of trust funds; or (b) for
any other reason, including (without limitation) by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over Payees or any of their property, or (ii) any settlement or compromise of any such
claim effected by Payees with any such claimant (including ISCO); then, and in such event, Guarantor agrees that any such judgment, decree, 
  

 3 

 order, settlement or compromise shall be binding upon Guarantor, notwithstanding any revocation hereof or the
cancellation of any Notes or other instrument or document evidencing any of the Obligations and the obligations of Guarantor hereunder shall continue to apply, or shall automatically (and without further action) be reinstated if not then in effect,

and arising out of, relating to or in connection with any of the Obligations.

delay on the part of Payees in exercising any of their options, powers or rights, or partial or single exercise thereof, shall constitute a waiver thereof. No waiver of any of their rights hereunder, and no modification or amendment of this

shall in no way impair the rights of Payees or the obligations of Guarantor to Payees in any other respect at any other time. 
 Section 6. Enforcement, Etc. Payees, in their sole discretion, may proceed to exercise or enforce any right, power, privilege, remedy or interest that Payees may have under this Guaranty, the Obligations or any applicable
law: at law, in equity, in rem or in any other forum available under applicable law; without notice except as otherwise expressly required by law provided herein; without pursuing, exhausting or otherwise exercising or enforcing any other right,
power, privilege, remedy or interest that Payees may have against or in respect of Guarantor, the Obligations, ISCO, any other guarantor, surety, pledgor, collateral or any other person or thing; and without regard to any act or omission of Payees
or any other person. Each Payee may enforce this Guaranty individually as to its portion of the Obligations.
