Exhibit 10.3

COMPLETION, PAYMENT AND PERFORMANCE GUARANTY

THIS COMPLETION, PAYMENT AND PERFORMANCE GUARANTY (this “Guaranty”), dated as of
July 11, 2006, is made and entered into by ALEXION PHARMACEUTICALS, INC., a
Delaware corporation (“Guarantor”), in favor of iSTAR FINANCIAL INC., a Maryland
corporation (collectively, with its successors and/or assigns, “Lender”), with
an address for notice hereunder of 1114 Avenue of the Americas, 27th Floor, New
York, New York 10036.

Background

A. ALEXION MANUFACTURING LLC, a Delaware limited liability company (the
“Borrower”) and Lender have entered into that certain Loan Agreement (as
amended, modified, supplemented or restated from time to time, the “Loan
Agreement”), dated of even date herewith, wherein, among other things, Lender
has agreed to make, and Borrower has agreed to accept, a loan in an original
maximum principal amount up to TWENTY SIX MILLION AND 00/100 DOLLARS
($26,000,000.00) (the “Loan”) upon the terms and conditions set forth in the
Loan Agreement. Any capitalized term used but not defined in this Guaranty shall
have the meaning ascribed to such term in the Loan Agreement.

B. The Loan is evidenced by a Promissory Note, dated of even date herewith, in
the original principal amount of up to $26,000,000.00 (together with any notes
given in substitution or exchange from time to time, as such Promissory Note and
substitute or exchange notes may, from time to time, be amended, modified,
supplemented or restated, the “Note”). The Note is secured by, among other
things, a Construction Mortgage Deed, Assignment of Leases and Rents, Security
Agreement, and Fixture Filing of even date herewith (as amended, modified,
supplemented or restated from time to time, the “Mortgage”).

C. Guarantor is the sole member of Borrower.

D. It is a condition to the making of the Loan that Guarantor execute and
deliver this Guaranty.

NOW, THEREFORE, in consideration of the Loan, and for other good and valuable
consideration, the receipt whereof is hereby acknowledged, Guarantor and its
successors and assigns, hereby covenants and agrees with Lender for the benefit
of Lender, its endorsees, participants, successors and assigns, as follows:

1. Guaranty.

(a) Scope of Guaranty. Guarantor as a primary obligor and not merely as a
surety, hereby absolutely, unconditionally and irrevocably guarantees to Lender
the prompt and complete payment (and performance, in the case of non-pecuniary
obligations) of all of the Guaranteed Obligations (as defined below) in full,
when and as the same shall become due, whether on any due date or performance
date or at stated maturity thereof, or by declaration, acceleration or required
payment, or upon demand or otherwise (including amounts and

--------------------------------------------------------------------------------

performance that would become due but for the operation of the automatic stay
under Section 362(a) of the United States Bankruptcy Code, Title 11, United
States Code, as amended (the “Bankruptcy Code”).

Guarantor hereby agrees, in furtherance of the foregoing and not in limitation
of any other right that the Lender may have at law or in equity against
Guarantor by virtue hereof, that upon the failure of Borrower to pay or perform
any of the Guaranteed Obligations when and as the same shall become due (or, as
provided below, would have become due), whether at stated maturity or due date
or performance date, as the case may be, by required payment or prepayment,
declaration, acceleration, demand or otherwise (including without limitation
amounts that would have become due, or could have been accelerated, but for the
operation of the automatic stay under Section 362(a) of the Bankruptcy Code,
whether or not any Creditor has taken any action to enforce or exercise any
right or remedy in respect of the Guaranteed Obligations, and interest and fees
which, but for the filing of a petition in bankruptcy with respect to Borrower,
would have accrued and become due on, or constituting, such Guaranteed
Obligations, whether or not a claim is allowed against Borrower for such amounts
in any such bankruptcy proceeding), Guarantor will forthwith pay and perform, or
cause to be paid and performed, all Guaranteed Obligations then due (or that
would have accrued and/or become due but for the filing of a petition in
bankruptcy with respect to Borrower) as aforesaid, and all other Guaranteed
Obligations then owed to the Lender as aforesaid.

(b) Obligations Guaranteed. As used in this Guaranty, “Guaranteed Obligations”
means, collectively: (1) the prompt and complete payment of the all principal
and interest payments and all other amounts, when due, in accordance with the
Loan Agreement, including, without limitation, the Loan, whether at stated
maturity or otherwise, (2) the payment and performance of all Obligations as
defined in the Loan Agreement, as and when due, and (3) all of the obligations,
duties and agreements of Borrower under the Loan Agreement and the other Loan
Documents relating to the construction, renovation, redevelopment, equipping and
furnishing of the Mortgaged Property and the Completion of the Initial
Construction Work in accordance with the Project Plans and Specifications, all
applicable Legal Requirements and all provisions of the Loan Documents. Without
limiting the generality of the foregoing, Guarantor absolutely, irrevocably and
unconditionally guarantees to Lender that:

(i) Borrower shall timely construct, renovate, redevelop, equip, furnish and
substantially complete and achieve Substantial Completion of Initial
Construction Work on or before Required Completion Date in compliance with the
Project Plans and Specifications, applicable Legal Requirements and the Loan
Documents;

(ii) The Borrower shall keep the Loan “in balance” (as more particularly
described in Section 3.2(d) of the Loan Agreement);

(iii) The Borrower shall fully and punctually deposit amounts required to be
paid pursuant to the loan balancing provisions of Section 3.2(d) of the Loan
Agreement;

 

- 2 -

--------------------------------------------------------------------------------

(iv) Borrower shall fully and punctually pay and discharge any and all costs and
expenses and liabilities incurred for or in connection with the construction,
renovation, redevelopment, equipping, furnishing and Completion of Initial
Construction Work, when and as the same may become due and payable, and also pay
and discharge any and all claims and demands for labor and materials used and
services rendered for or in connection with the construction, renovation,
redevelopment and Completion Initial Construction Work and/or installation of
all items of fixtures, furnishings and equipment and other personalty in
connection therewith; and

(v) The Mortgaged Property shall be and remain free and clear of any and all
Liens, claims, and demands from any and all Persons furnishing materials, labor
or services for or in connection with the construction, equipping, furnishing or
completion of the Initial Construction Work and/or the installation of all items
of fixtures, furnishings and equipment and other personalty in connection
therewith.

(c) Indemnity, Reimbursement and Performance. In the event that Borrower does
not fully perform the Guaranteed Obligations, then:

(i) Guarantor shall, within ten (10) days of demand by Lender, perform the
Guaranteed Obligations;

(ii) In the event that Guarantor fails to commence performance under the
immediately preceding Section l(c)(i) (i) within ten (10) Business Days after
Lender’s written demand and to diligently prosecute such performance to
completion thereof, and if Lender shall (a) cause any construction, renovation,
redevelopment, equipping and furnishing of the Initial Construction Work and the
Project Improvements, or takes any action whatsoever toward Completion of the
Project, (b) pay any costs in connection with the construction, renovation,
redevelopment, equipping and furnishing of the Initial Construction Work or the
completion of the Project Improvements, or (c) cause any lien, claim or demand
to be released or paid, then Guarantor shall promptly reimburse Lender within
ten (10) Business Days after written demand, for all sums paid and all costs and
expenses incurred by Lender in connection therewith; and

(iii) Guarantor will fully indemnify, defend and save Lender harmless from all
actual out of pocket third party costs and damages (including reasonable
attorney’s fees, including any diminution in value) that Lender may suffer by
reason of Guarantor’s failure to promptly and fully perform under the
immediately preceding Section l(c) (i) and (ii) above. In no event shall the
indemnification contained herein include consequential or punitive damages.

(d) Balancing. If, at any time and for any reason, Borrower shall fail to
deposit amounts required to be deposited by Section 3.2 of the Loan Agreement
within the ten (10) Business Day period provided therein for such payment, then
Guarantor shall, within five (5) Business Days after a written request by
Lender, deposit with Lender cash in an amount sufficient to cover the deficiency
not paid by Borrower. Lender shall hold and apply such deposited cash as
provided in the Loan Agreement.

 

- 3 -

--------------------------------------------------------------------------------

(e) Enforcement Costs. In addition to the foregoing payment obligations,
Guarantor further agrees to pay any and all actual out of pocket third party
costs and other expenses (the “Enforcement Costs”) that may be paid or incurred
directly or indirectly by each of the Lender in, or allocable to, collecting any
or all of the Guaranteed Obligations and/or preserving and/or enforcing any
rights and remedies under this Guaranty and/or in respect of the Guaranteed
Obligations (including, without limitation, all reasonable fees and expenses
incurred by the Lender and its respective agents and representatives in
connection with any default or event of default, beyond any applicable notice
and cure period, relating to, or other breach or violation of, this Guaranty
and/or Guaranteed Obligation and, to the extent the Lender from time to time
deem it necessary to employ counsel and/or consultants for any purpose relating
to this Guaranty and/or any Guaranteed Obligation, the reasonable fees and
expenses of such counsel and/or consultants). For purposes of this paragraph,
the term “counsel” includes attorneys who are employees of Lender acting as
counsel for Lender, and the terms “costs and expenses” and “fees and expenses”
shall include, without limitation, the fees charged by Lender for its in-house
counsel provided such fees are within the range of fees charged by attorneys of
similar experience at medium to large sized law firms located in the City of
Chicago, Illinois.

(f) Maximum Amount of Guaranty. Guarantor shall be liable under this Guaranty
for the maximum amount of such liability that can be hereby incurred without
rendering this Guaranty, as it relates to Guarantor, voidable under applicable
Legal Requirements relating to fraudulent conveyance or fraudulent transfer, and
not for any greater amount.

(g) Continuing Guaranty. This is an irrevocable, absolute, continuing guaranty
of payment and performance. This Guaranty may not be revoked by Guarantor and
shall continue to be effective with respect to the Guaranteed Obligations
arising or created after any attempted revocation by Guarantor and after
Guarantor’s dissolution (in which event this Guaranty shall be binding upon
Guarantor’s successors and assigns). It is the intent of Guarantor that the
obligations and liabilities of Guarantor hereunder are absolute and
unconditional under any and all circumstances and that until the Guaranteed
Obligations are fully, finally and indefeasibly satisfied, such obligations and
liabilities shall not be discharged or released in whole or in part, by any act
or occurrence which might, but for the provisions of this Guaranty, be deemed a
legal or equitable discharge or release of Guarantor. Each and every default,
beyond any applicable notice and cure period, in payment of any amounts due or
performance of any obligation required under this Guaranty shall give rise to a
separate cause of action hereunder, and separate suits may be brought hereunder
as each cause of action arises, or, in the discretion of Lender, may be brought
as a consolidated suit or suits.

2. Waivers.

(a) Guarantor hereby assents to all terms and agreements heretofore or hereafter
made by Borrower with the Lender, and, to the fullest extent permitted by
applicable law, waives notice of:

(i) Any loans or advances made by the Lender to Borrower under the Loan
Documents;

 

- 4 -

--------------------------------------------------------------------------------

(ii) The present existence or future incurring of any of the indebtedness
pursuant to the Note or any future modifications thereof or any terms or amounts
thereof or any Guaranteed Obligations or any terms or amounts thereof;

(iii) The obtaining or release of any guaranty or surety agreement (in addition
to this Guaranty), pledge, assignment, or other security for any of the
indebtedness evidenced by the Note, or any Guaranteed Obligations; and

(iv) Notice of protest, default, notice of intent to accelerate and notice of
acceleration in relation to any instrument relating to the indebtedness
evidenced by the Note or any Guaranteed Obligations.

(b) Guarantor hereby waives, to the fullest extent permitted by applicable law,
any rights and defenses which such Guarantor might have as a result of any
representation, warranty or statement made by the Lender or its agents to such
Guarantor in order to induce Guarantor to execute this Guaranty.

(c) Regardless of whether Guarantor may have made any payments to the Lender,
until the Loan is indefeasibly paid in full and except as set forth in
Section 10 hereof, Guarantor hereby waives, to the fullest extent permitted by
applicable law: (i) all rights of subrogation, indemnification, contribution and
any other rights to collect reimbursement from Borrower or any other party for
any sums paid to the Lender, whether contractual or arising by operation of law
(including the United States Bankruptcy Code or any successor or similar
statute) or otherwise, (ii) all rights to enforce any remedy that the Lender may
have against Borrower, and (iii) all rights to participate in any security now
or later to be held by the Lender for the Loan.

(d) Guarantor further waives, to the fullest extent permitted by applicable law,
any defense to the recovery by the Lender against Guarantor of any deficiency or
otherwise to the enforcement of this Guaranty or any security for this Guaranty
based upon Creditor’s election of any remedy against Guarantor or Borrower,
including the defense to enforcement of this Guaranty by virtue of any
“anti-deficiency” statutes and their application following a non- judicial
foreclosure sale.

3. Events and Circumstances Not Reducing or Discharging Guarantor’s Obligations.
Guarantor hereby consents and agrees to each of the following, and agrees that
Guarantor’s obligations under this Guaranty shall not be released, diminished,
impaired, reduced or adversely affected by any of the following, and waives, to
the fullest extent permitted by applicable law, any rights and defenses
(excluding the rights to notice, if any, as herein provided or as required by
law) which Guarantor might have otherwise as a result of or in connection with
any of the following:

(a) any and all extensions, modifications, adjustments, indulgences,
forbearances or compromises that might be granted or given by the Lender to
Borrower, including, without limitation, any and all amendments, modifications,
supplements, extensions or restatements of any of the Loan Documents;

 

- 5 -

--------------------------------------------------------------------------------

(b) the insolvency, bankruptcy, rearrangement, adjustment, composition,
liquidation, disability, dissolution or lack of power of Borrower or any other
party at any time liable for the payment of all or part of the indebtedness
evidenced by the Note or any Guaranteed Obligations; or any dissolution,
consolidation or merger of Borrower or Guarantor, or any sale, lease or transfer
of any or all of the assets of Borrower or Guarantor, or any changes in the
ownership, partners or members of Borrower or Guarantor;

(c) the invalidity, illegality or unenforceability of all or any part of the
indebtedness evidenced by the Note or any Guaranteed Obligations, or any
document or agreement executed in connection with the indebtedness evidenced by
the Note or any Guaranteed Obligations, for any reason whatsoever, including,
without limitation, the fact that the indebtedness evidenced by the Note, or any
part thereof exceeds the amount permitted by law, the act of creating the
indebtedness evidenced by the Note or any Guaranteed Obligations or any part
thereof is ultra vires, the representatives executing the Note or the other Loan
Documents or otherwise creating the indebtedness evidenced by the Note or any
Guaranteed Obligations acted in excess of their authority, the indebtedness
evidenced by the Note violates applicable usury laws, Borrower has valid
defenses, claims or offsets (whether at law, in equity or by agreement) which
render the indebtedness evidenced by the Note or any Guaranteed Obligations
wholly or partially uncollectible from Borrower, the creation, performance or
repayment of the indebtedness evidenced by the Note or any Guaranteed
Obligations is illegal, uncollectible, legally impossible or unenforceable, or
any of the other Loan Documents pertaining to the indebtedness evidenced by the
Note or any Guaranteed Obligations are irregular or not genuine or authentic;
provided, however, the foregoing shall not prohibit Guarantor from (i) asserting
a defense of performance, (ii) asserting a compulsory counterclaim on an action
brought under this Guaranty, or (iii) subject to the remaining terms of the Loan
Documents, bringing a separate action against Lender for breaches of Lender’s
obligations under the Loan Documents;

(d) the taking or accepting of any other security, collateral or guaranty, or
other assurance of the payment, for all or any of the indebtedness evidenced by
the Note or any Guaranteed Obligations;

(e) any release, surrender or exchange of any collateral, property or security,
at any time existing in connection with, or assuring or securing payment of, all
or any part of the indebtedness evidenced by the Note or the Guaranteed
Obligations;

(f) the failure of the Lender or any other party to exercise diligence or
reasonable care in the preservation, protection, enforcement, sale or other
handling or treatment of all or any part of such collateral, property or
security;

(g) the fact that any collateral, security, security interest or lien
contemplated or intended to be given, created or granted as security for the
repayment of the indebtedness evidenced by the Note or Guaranteed Obligations
shall not be properly perfected or created, or shall prove to be unenforceable
or subordinate to any other security interest or lien, it being recognized and
agreed by Guarantor that Guarantor is not entering into this Guaranty in
reliance on, or in contemplation of the benefits of, the validity,
enforceability, collectibility or value of

 

- 6 -

--------------------------------------------------------------------------------

any of the collateral for the indebtedness evidenced by the Note or the
Guaranteed Obligations; or

(h) any payment by Borrower to the Lender is held to constitute a preference
under the Bankruptcy Code, or for any reason the Lender is required to refund
such payment or pay such amounts to such Borrower, or any other Person.

It is the unambiguous and unequivocal intention of Guarantor that Guarantor
shall be obligated to pay and perform the Guaranteed Obligations when due,
notwithstanding any occurrence, circumstance, event, action or omission
whatsoever, whether contemplated or uncontemplated, and whether or not otherwise
or particularly described herein, except for the full and final payment and
satisfaction of all Guaranteed Obligations.

4. Payment by Guarantor. If the Guaranteed Obligations, or any part thereof, are
not punctually paid or performed (following the expiration of any applicable
notice and cure periods), as the case may be, Guarantor shall, immediately
within ten (10) days of demand and without protest or notice of protest, pay the
amount due thereon to the Lender, at its address set forth above or as otherwise
designated by the Lender. Such demand(s) may be made at any time coincident with
or after the time for payment or performance of all or part of the Guaranteed
Obligations. Such demand shall be deemed made if given in accordance with
Section 18 hereof. It shall not be necessary for the Lender, in order to enforce
such payment or performance by Guarantor, first to institute suit or exhaust its
remedies against Borrower, or others liable to pay or perform such Guaranteed
Obligations, or to enforce its rights against any security which shall ever have
been given to secure the Guaranteed Obligations. The Lender shall not be
required to mitigate damages or take any other action to reduce, collect or
enforce the indebtedness evidenced by the Note or Guaranteed Obligations.

5. Indebtedness or Other Obligations of Guarantor. If Guarantor is or becomes
liable for any indebtedness owed by Borrower to the Lender by endorsement or
otherwise than under this Guaranty, such liability shall not be in any manner
impaired or affected by this Guaranty, and the rights of the Lender hereunder
shall be cumulative of any and all other rights that Lender may ever have
against Guarantor. The exercise by the Lender of any right or remedy hereunder
or under any other instrument or at law or in equity shall not preclude the
concurrent or subsequent exercise of any other instrument or remedy at law or in
equity and shall not preclude the concurrent or subsequent exercise of any other
right or remedy. Further, without in any way diminishing or limiting the
generality of the foregoing, it is specifically understood and agreed that this
Guaranty is given by Guarantor as an additional guaranty to any and all
guarantees hereafter executed and delivered to the Lender by Guarantor in favor
of the Lender relating to the indebtedness and obligations of Borrower to the
Lender, and nothing herein shall ever be deemed to replace or be in lieu of any
other of such previous or subsequent guarantees.

6. Application of Payments. If, at any time, there is any indebtedness or
obligations (or any portion thereof) of Borrower to the Lender which is not
guaranteed by Guarantor, the Lender, without in any manner impairing its rights
hereunder, may, at its option, apply all amounts realized by the Lender from
collateral or security held by the Lender first to the payment of such
unguaranteed indebtedness or obligations, with the remaining amounts, if any, to
then be applied to the payment of the indebtedness or obligations guaranteed by
Guarantor.

 

- 7 -

--------------------------------------------------------------------------------

7. Suits, Releases of Settlements with Others. Guarantor agrees that the Lender,
in its sole discretion, may bring suit against any other guarantor without
impairing the rights of the Lender or its successors and assigns against
Guarantor or any other guarantor of the Guaranteed Obligations; and the Lender
may settle or compromise with such other guarantor for such sum or sums as the
Lender may see fit and release such other guarantor from all further liability
to the Lender, all without impairing its rights against Guarantor.

8. Warranties, Representations and Covenants.

(a) Guarantor warrants and represents, as follows:

(i) Guarantor has received, or will receive, direct or indirect benefit from the
making of this Guaranty, the making of the Loan and the entering into and
execution of the Loan Agreement and the Loan Documents in connection therewith;

(ii) Guarantor is familiar with, and has independently reviewed the financial
condition of the Borrower and is familiar with the value of any and all
collateral intended to be created as security for the payment and performance of
the indebtedness evidenced by the Note and the Guaranteed Obligations, and
Guarantor assumes full responsibility for keeping fully informed as to such
matters in the future; however, Guarantor is not relying on such financial
condition or the collateral as an inducement to enter into this Guaranty; and

(iii) All financial statements concerning Guarantor which have been or will
hereafter be furnished by Guarantor or Borrower to the Lender pursuant to the
Loan Documents, have been or will be prepared in accordance with GAAP
consistently applied (except as disclosed therein, to the extent the Lender
approves such disclosure; provided that the Lender’s approval shall not be
required so long as (a) Guarantor is a reporting company under the Exchange Act,
and (b) Guarantor’s financial statements are audited by a so-called “Big-4”
accounting firm) and, in all material respects, present fairly the financial
condition of the Persons covered thereby as at the dates thereof and the results
of their operations for the periods then ended.

(iv) No ERISA Affiliate of Guarantor maintains or contributes to, or has any
obligation under, any Employee Benefit Plans. Guarantor is not an “employee
benefit plan” (within the meaning of section 3(3) of ERISA) to which ERISA
applies and Guarantor’s assets do not constitute plan assets. No actions, suits
or claims under any laws and regulations promulgated pursuant to ERISA are
pending or, to Guarantor’s knowledge, threatened against Guarantor. Guarantor
has no knowledge of any material liability incurred by Guarantor which remains
unsatisfied for any taxes or penalties with respect to any employee benefit plan
or any Multiemployer Plan, or of any lien which has been imposed on Guarantor’s
assets pursuant to section 412 of the Code or sections 302 or 4068 of ERISA. The
Loan, the execution, delivery and performance of the Loan Documents and the
transactions contemplated by this Guaranty do not constitute a non-exempt
prohibited transaction under ERISA or the Code. Guarantor is an “operating
company” as defined in ERISA.

 

- 8 -

--------------------------------------------------------------------------------

(v) As of the date hereof, and after giving effect to this Guaranty and the
contingent obligations evidenced hereby, Guarantor is and expects to be solvent
at all times, and has and expects to have assets at all times which, fairly
valued, exceed his or its obligations, liabilities and debts, and has and
expects to have property and assets at all times sufficient to satisfy and repay
its obligations and liabilities.

(b) Guarantor covenants and agrees that, for so long as this Guaranty remains in
effect, Guarantor shall not liquidate, wind-up or dissolve itself (or suffer any
liquidation or dissolution).

9. Subordination. If, for any reason Borrower is now or hereafter becomes
indebted to Guarantor (such indebtedness and all interest thereon being referred
to as the “Affiliated Debt”), such Affiliated Debt shall, at all times, be
subordinate in all respects to the full payment and performance of the
obligations evidenced by the Note, and Guarantor shall not be entitled to
enforce or receive payment thereof until all of the obligations evidenced by the
Note have been fully paid. Guarantor agrees that any liens, mortgages, deeds of
trust, security interests, judgment liens, charges or other encumbrances upon
Borrower’s assets securing payment of the Affiliated Debt shall be and remain
subordinate and inferior to any liens, security interests, judgment liens,
charge or other encumbrances upon Borrower’s assets securing the payment of the
obligations evidenced by the Note and Guaranteed Obligations, and without the
prior written consent of the Lender, Guarantor shall not exercise or enforce any
creditor’s rights of any nature against Borrower to collect the Affiliated Debt
(other than demand payment therefor). In the event of the receivership,
bankruptcy, reorganization, arrangement, debtor’s relief or other insolvency
proceedings involving Borrower as a debtor, to the fullest extent permitted by
law, the Lender shall have the right and authority, either in its own name or as
attorney-in-fact for Guarantor, to file such proof of debt claim, petition or
other documents and to take such other steps as are necessary to prove its
rights hereunder.

10. Waiver of Subrogation. Notwithstanding any other provision of this Guaranty
to the contrary, until the Loan is indefeasibly paid in full, Guarantor hereby
waives any claim or other rights which Guarantor may now have or hereafter
acquire against Borrower or any other guarantor of all or any of the obligations
that arise from the existence or performance of Guarantor’s obligations under
this Guaranty (all such claims and rights are referred to as “Guarantor’s
Conditional Rights”), including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, or indemnification, any right to
participate in any claim or remedy of the Lender against Borrower or any
security or collateral which the Lender now has or hereafter acquires, whether
or not such claim, remedy or right arises in equity or under contract, statute
(including the Bankruptcy Code or any successor or similar statute) or common
law, by any payment made hereunder or otherwise, including without limitation,
the right to take or receive from Borrower, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or security on
account of such claim or other rights. If, notwithstanding the foregoing
provisions, any amount shall be paid to Guarantor on account of Guarantor’s
Conditional Rights and either (i) such amount is paid to Guarantor at any time
when the Guaranteed Obligations shall not have been paid or performed in full,
or (ii) regardless of when such amount is paid to Guarantor, any payment made by
Borrower to the Lender is subsequently invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid by the Lender or paid over to a
trustee, receiver or any other entity, whether under any

 

- 9 -

--------------------------------------------------------------------------------

bankruptcy act or otherwise (such payment, a “Preferential Payment”), then such
amount paid to Guarantor shall be held in trust for the benefit of the Lender
and shall forthwith be paid to the Lender to be credited and applied upon the
Guaranteed Obligations, whether matured or unmatured, in such order as the
Lender, in its sole and absolute discretion, shall determine. The foregoing
waivers shall be effective until the Guaranteed Obligations have been paid and
performed in full.

11. Impairment of Subrogation Rights; Waivers of Rights Under the
Anti-Deficiency Rules.

(a) Guarantor agrees that upon the occurrence and during the continuance of an
Event of Default under the Loan Documents, the Lender in its sole discretion,
without prior notice to or consent of Guarantor, may elect to (i) foreclose
either nonjudicially or judicially against any real or personal property
security (including, without limitation, the Mortgaged Property) it holds for
the obligations evidenced by the Note or any Guaranteed Obligations, or any part
thereof, (ii) accept any transfer or assignment of any such security in lieu of
foreclosure, (iii) compromise or adjust any part of such obligations, or
(iv) make any other accommodation with Borrower or Guarantor, or exercise any
other remedy against Borrower or any collateral or security. No such action by
the Lender will release or limit the liability of Guarantor to the Lender, who
shall remain liable under this Guaranty after the action, even if the effect of
that action is to deprive Guarantor of the right to collect reimbursement from
Borrower or any other person for any sums paid to the Lender or Guarantor’s
rights of subrogation, contribution, or indemnity against Borrower or any other
person. Without limiting the foregoing, it is understood and agreed that on any
foreclosure or assignment in lieu of foreclosure of any collateral or security
held by the Lender, such security will no longer exist and that any right that
Guarantor might otherwise have, on full payment of the Guaranteed Obligations by
Guarantor to the Lender, to participate in any such security or to be subrogated
to any rights of the Lender with respect to any such security will be
nonexistent; nor shall Guarantor be deemed to have any right, title, interest or
claim under any circumstances in or to any real or personal property held by the
Lender or any third party following any foreclosure or assignment in lieu of
foreclosure of any such security.

(b) Guarantor understands and acknowledges that if the Lender forecloses
judicially or nonjudicially against any real property security for Borrower’s
obligations, such foreclosure could impair or destroy any right or ability that
Guarantor may have to seek reimbursement, contribution, or indemnification for
any amounts paid by Guarantor under this Guaranty.

(c) Without limiting the foregoing, Guarantor waives, to the fullest extent
permitted by applicable law, all rights and defenses arising out of an election
of remedies by the Lender, even though that election of remedies, such as
nonjudicial foreclosure with respect to security for a guaranteed obligation,
may adversely affect Guarantor’s rights of subrogation and reimbursement against
Borrower.

(d) Guarantor intentionally, freely, irrevocably and unconditionally waives and
relinquishes, to the fullest extent permitted by applicable law, all rights
which may be available to it under any provision of applicable law to limit the
amount of any deficiency

 

- 10 -

--------------------------------------------------------------------------------

judgment or other judgment which may be obtained against Guarantor under this
Guaranty to not more than the amount by which the unpaid Guaranteed Obligations
plus all other indebtedness due from Borrower under the Loan Documents exceeds
the fair market value or fair value of any real or personal property securing
said obligations and any other indebtedness due from Borrower under the Loan
Documents, including, without limitation, all rights to an appraisement of,
judicial or other hearing on, or other determination of the value of said
property. Guarantor acknowledges and agrees that, as a result of the foregoing
waiver, the Lender may be entitled to recover from Guarantor an amount which,
when combined with the value of any real or personal property foreclosed upon by
the Lender (or the proceeds of the sale of which have been received by the
Lender) and any sums collected by the Lender from Borrower or other Persons,
might exceed the amount of the Guaranteed Obligations plus all other
indebtedness due from Borrower under the Loan Documents.

(e) Guarantor understands and agrees that the Lender may have the ability to
pursue Guarantor for a judgment on the Guaranteed Obligations without having
first foreclosed on the real property security for such Guaranteed Obligations,
that the Lender may have the ability to sue Guarantor for a deficiency judgment
on the Guaranteed Obligations after a non-judicial foreclosure sale or,
regardless of any election of remedies by the Lender, if the Guaranteed
Obligations or any of the other indebtedness of Borrower to the Lender under the
Loan Documents is considered to have been provided by a vendor to a buyer and to
evidence part of the purchase price for the real property security, and that the
Lender may be able to recover from Borrower an amount which, when combined with
the fair market value of the property acquired by the Lender in a foreclosure
sale or the proceeds of the foreclosure sale received by the Lender, might
exceed the amount of the Guaranteed Obligations due and owing by Guarantor and
the amounts payable under the Loan Documents.

(f) Without limiting any of the other waivers and provisions set forth in this
Guaranty, Guarantor waives all rights and defenses that Guarantor may have
because Borrower’s debt is secured by real property; this means, among other
things: (a) the Lender may collect from Guarantor without first foreclosing on
any real or personal property collateral pledged by Borrower; (b) the amount of
the Guaranteed Obligations 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; (c) the Lender may collect from Guarantor even if the
Lender, by foreclosing on the real property collateral, has destroyed any right
Guarantor may have to collect from Borrower. This is an unconditional and
irrevocable waiver of any rights and defenses Guarantor may have because the
indebtedness evidenced by the Note is secured by real property.

Notwithstanding the foregoing or any provisions of Section 11(a) hereof, nothing
contained in this Guaranty shall in any way be deemed to imply that any other
state’s law other than the law of the State of New York shall govern this
Guaranty or any of the Loan Documents in any respect, except as expressly set
forth therein, including with respect to the exercise of the Lender’s remedies
under the Loan Documents.

Notwithstanding any other provision herein to the contrary, upon the
indefeasible payment in full of the Note, Guarantor shall have all rights of
subrogation available at law or in equity.

assigns, and in the event of an assignment by the Lender, its successors and
assigns, of the obligations evidenced by the Note, or any part or parts thereof,
the rights and benefits hereunder, to the extent applicable to the obligations
so assigned, shall be transferred with such obligations.

13. No Release if Preference, Refund, Etc. In the event any payment by Borrower
to the Lender is determined to be a preferential payment under any applicable
bankruptcy or insolvency laws, or if for any reason the Lender is required to
refund part or all of any payment or pay the amount thereof to any other party,
such repayment by the Lender to Borrower shall not constitute a release of
Guarantor from any liability hereunder, and Guarantor agrees to pay such amount
to the Lender upon demand to the extent such amount constitutes a Guaranteed
Obligation.

14. Right of Set-Off. In addition to any other rights now or hereafter granted
under applicable law and not by way of limitation of any such rights, upon
Guarantor’s failure to pay the Guaranteed Obligations, within ten (10) days of
demand by the Lender, the Lender is hereby authorized at any time and from time
to time, without notice to Guarantor or to any other person, to set off and to
appropriate and to apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by the Lender to or for the credit or the
account of Guarantor against or on account of the obligations evidenced by the
Note.
