(b)  Subject to definitions contained in other Articles of the Uniform Commercial Code that apply to particular Articles or parts thereof:

(2)  "Aggrieved party" means a party entitled to     pursue a remedy.
(3)  "Agreement", as distinguished from "contract",     means the bargain of the parties in fact, as found in their language or inferred from other circumstances, including course of performance, course of dealing, or usage of trade as provided in Section 1-303.
(4)  "Bank" means a person engaged in the business of     banking and includes a savings bank, savings and loan association, credit union, and trust company.
(5)  "Bearer" means a person in possession of a     negotiable instrument, document of title, or certificated security that is payable to bearer or indorsed in blank.

(7)  "Branch" includes a separately incorporated     foreign branch of a bank.
(8)  "Burden of establishing" a fact means the burden     of persuading the trier of fact that the existence of the fact is more probable than its nonexistence.
(9)  "Buyer in ordinary course of business" means a     person that buys goods in good faith, without knowledge that the sale violates the rights of another person in the goods, and in the ordinary course from a person, other than a pawnbroker, in the business of selling goods of that kind.  A person buys goods in the ordinary course if the sale to the person comports with the usual or customary practices in the kind of business in which the seller is engaged or with the seller's own usual or customary practices.  A person that sells oil, gas, or other minerals at the wellhead or minehead is a person in the business of selling goods of that kind.  A buyer in ordinary course of business may buy for cash, by exchange of other property, or on secured or unsecured credit, and may acquire goods or documents of title under a preexisting contract for sale.  Only a buyer that takes possession of the goods or has a right to recover the goods from the seller under Article 2 may be a buyer in ordinary course of business.

(A) a heading in capitals equal to or greater in         size than the surrounding text, or in contrasting type, font, or color to the surrounding text of the same or lesser size; and
(B) language in the body of a record or display         in larger type than the surrounding text, or in contrasting type, font, or color to the surrounding text of the same size, or set off from surrounding text of the same size by symbols or other marks that call attention to the language.
(11)  "Consumer" means an individual who enters into     a transaction primarily for personal, family, or household purposes.
(12)  "Contract", as distinguished from "agreement",     means the total legal obligation that results from the parties' agreement as determined by the Uniform Commercial Code as supplemented by any other applicable laws.
(13)  "Creditor" includes a general creditor, a     secured creditor, a lien creditor, and any representative of creditors, including an assignee for the benefit of creditors, a trustee in bankruptcy, a receiver in equity, and an executor or administrator of an insolvent debtor's or assignor's estate.

(20)  "Good faith" means honesty in fact in the     conduct or transaction concerned.
(21)  "Holder" means:
(A) the person in possession of a negotiable         instrument that is payable either to bearer or to an identified person that is the person in possession; or
(B) the person in possession of a document of         title if the goods are deliverable either to bearer or to the order of the person in possession.
(22)  "Insolvency proceeding" includes an assignment     for the benefit of creditors or other proceeding intended to liquidate or rehabilitate the estate of the person involved.

(29)  "Purchase" means taking by sale, lease,     discount, negotiation, mortgage, pledge, lien, security interest, issue or reissue, gift, or any other voluntary transaction creating an interest in property.
(30)  "Purchaser" means a person that takes by     purchase.
(31)  "Record" means information that is inscribed on     a tangible medium or that is stored in an electronic or other medium and is retrievable in perceivable form.
(32)  "Remedy" means any remedial right to which an     aggrieved party is entitled with or without resort to a tribunal.

(34)  "Right" includes remedy.

"Security interest" includes any interest of a consignor and a buyer of accounts, chattel paper, a payment intangible, or a promissory note in a transaction that is subject to Article 9.  "Security interest" does not include the special property interest of a buyer of goods on identification of those goods to a contract for sale under Section 2-401, but a buyer may also acquire a "security interest" by complying with Article 9.  Except as otherwise provided in Section 2-505, the right of a seller or lessor of goods under Article 2 or 2A to retain or acquire possession of the goods is not a "security interest", but a seller or lessor may also acquire a "security interest" by complying with Article 9.  The retention or reservation of title by a seller of goods notwithstanding shipment or delivery to the buyer under Section 2-401 is limited in effect to a reservation of a "security interest".  Whether a transaction in the form of a lease creates a "security interest" is determined pursuant to Section 1-203.
(36)  "Send" in connection with a writing, record, or     notice means:
(A) to deposit in the mail or deliver for         transmission by any other usual means of communication with postage or cost of transmission provided for and properly addressed and, in the case of an instrument, to an address specified thereon or otherwise agreed, or if there be none to any address reasonable under the circumstances; or
(B) in any other way to cause to be received any         record or notice within the time it would have arrived if properly sent.
(37)  "Signed" includes using any symbol executed or     adopted with present intention to adopt or accept a writing.

(810 ILCS 5/1-202) (from Ch. 26, par. 1-202)
Sec. 1-202. Notice; knowledge.
(a)  Subject to subsection (f), a person has "notice" of a fact if the person:
(1) has actual knowledge of it;
(2) has received a notice or notification of it; or
(3) from all the facts and circumstances known to the     person at the time in question, has reason to know that it exists.
(b)  "Knowledge" means actual knowledge.  "Knows" has a corresponding meaning.
(c)  "Discover", "learn", or words of similar import refer to knowledge rather than to reason to know.
(d)  A person "notifies" or "gives" a notice or notification to another person by taking such steps as may be reasonably required to inform the other person in ordinary course, whether or not the other person actually comes to know of it.
(e)  Subject to subsection (f), a person "receives" a notice or notification when:
(1) it comes to that person's attention;  or
(2) it is duly delivered in a form reasonable under     the circumstances at the place of business through which the contract was made or at another location held out by that person as the place for receipt of such communications.
(f)  Notice, knowledge, or a notice or notification received by an organization is effective for a particular transaction from the time it is brought to the attention of the individual conducting that transaction and, in any event, from the time it would have been brought to the individual's attention if the organization had exercised due diligence.  An organization exercises due diligence if it maintains reasonable routines for communicating significant information to the person conducting the transaction and there is reasonable compliance with the routines.  Due diligence does not require an individual acting for the organization to communicate information unless the communication is part of the individual's regular duties or the individual has reason to know of the transaction and that the transaction would be materially affected by the information.

(810 ILCS 5/1-203) (from Ch. 26, par. 1-203)
Sec. 1-203. Lease distinguished from security interest.
(a)  Whether a transaction in the form of a lease creates a lease or security interest is determined by the facts of each case.
(b)  A transaction in the form of a lease creates a security interest if the consideration that the lessee is to pay the lessor for the right to possession and use of the goods is an obligation for the term of the lease and is not subject to termination by the lessee, and:
(1) the original term of the lease is equal to or     greater than the remaining economic life of the goods;
(2) the lessee is bound to renew the lease for the     remaining economic life of the goods or is bound to become the owner of the goods;
(3) the lessee has an option to renew the lease for     the remaining economic life of the goods for no additional consideration or for nominal additional consideration upon compliance with the lease agreement; or
(4) the lessee has an option to become the owner of     the goods for no additional consideration or for nominal additional consideration upon compliance with the lease agreement.
(c)  A transaction in the form of a lease does not create a security interest merely because:
(1) the present value of the consideration the lessee     is obligated to pay the lessor for the right to possession and use of the goods is substantially equal to or is greater than the fair market value of the goods at the time the lease is entered into;
(2) the lessee assumes risk of loss of the goods;
(3) the lessee agrees to pay, with respect to the     goods, taxes, insurance, filing, recording, or registration fees, or service or maintenance costs;
(4) the lessee has an option to renew the lease or to     become the owner of the goods;
(5) the lessee has an option to renew the lease for a     fixed rent that is equal to or greater than the reasonably predictable fair market rent for the use of the goods for the term of the renewal at the time the option is to be performed; or
(6) the lessee has an option to become the owner of     the goods for a fixed price that is equal to or greater than the reasonably predictable fair market value of the goods at the time the option is to be performed.
(d)  Additional consideration is nominal if it is less than the lessee's reasonably predictable cost of performing under the lease agreement if the option is not exercised.  Additional consideration is not nominal if:
(1) when the option to renew the lease is granted to     the lessee, the rent is stated to be the fair market rent for the use of the goods for the term of the renewal determined at the time the option is to be performed; or
(2) when the option to become the owner of the goods     is granted to the lessee, the price is stated to be the fair market value of the goods determined at the time the option is to be performed.
(e)  The "remaining economic life of the goods" and "reasonably predictable" fair market rent, fair market value, or cost of performing under the lease agreement must be determined with reference to the facts and circumstances at the time the transaction is entered into.

(1) in return for a binding commitment to extend     credit or for the extension of immediately available credit, whether or not drawn upon and whether or not a charge-back is provided for in the event of difficulties in collection;
(2) as security for, or in total or partial     satisfaction of, a preexisting claim;

(810 ILCS 5/1-301)
Sec. 1-301. Territorial applicability; parties' power to choose applicable law.
(a) Except as otherwise provided in this Section, when a transaction bears a reasonable relation to this State and also to another state or nation the parties may agree that the law either of this State or of such other state or nation shall govern their rights and duties.
(b) In the absence of an agreement effective under subsection (a), and except as provided in subsection (c), the Uniform Commercial Code applies to transactions bearing an appropriate relation to this State.
(c) If one of the following provisions of the Uniform Commercial Code specifies the applicable law, that provision governs and a contrary agreement is effective only to the extent permitted by the law so specified:
(1)  Section 2-402;
(2)  Sections 2A-105 and 2A-106;
(3)  Section 4-102;
(4)  Section 4A-507;
(5)  Section 5-116;

(Source: P.A. 95-895, eff. 1-1-09.)
(810 ILCS 5/1-302)
Sec. 1-302. Variation by agreement.
(a)  Except as otherwise provided in subsection (b) or elsewhere in the Uniform Commercial Code, the effect of provisions of the Uniform Commercial Code may be varied by agreement.
(b)  The obligations of good faith, diligence, reasonableness, and care prescribed by the Uniform Commercial Code may not be disclaimed by agreement.  The parties, by agreement, may determine the standards by which the performance of those obligations is to be measured if those standards are not manifestly unreasonable. Whenever the Uniform Commercial Code requires an action to be taken within a reasonable time, a time that is not manifestly unreasonable may be fixed by agreement.
(c)  The presence in certain provisions of the Uniform Commercial Code of the phrase "unless otherwise agreed", or words of similar import, does not imply that the effect of other provisions may not be varied by agreement under this Section.
(Source: P.A. 95-895, eff. 1-1-09.)
(810 ILCS 5/1-303)
Sec. 1-303. Course of performance, course of dealing, and usage of trade.
(a)  A "course of performance" is a sequence of conduct between the parties to a particular transaction that exists if:
(1) the agreement of the parties with respect to the     transaction involves repeated occasions for performance by a  party; and
(2) the other party, with knowledge of the nature of     the performance and opportunity for objection to it, accepts the performance or acquiesces in it without objection.
(b)  A "course of dealing" is a sequence of conduct concerning previous transactions between the parties to a particular transaction that is fairly to be regarded as establishing a common basis of understanding for interpreting their expressions and other conduct.
(c)  A "usage of trade" is any practice or method of dealing having such regularity of observance in a place, vocation, or trade as to justify an expectation that it will be observed with respect to the transaction in question.  The existence and scope of such a usage must be proved as facts.  If it is established that such a usage is embodied in a trade code or similar record, the interpretation of the record is a question of law.
(d)  A course of performance or course of dealing between the parties or usage of trade in the vocation or trade in which they are engaged or of which they are or should be aware is relevant in ascertaining the meaning of the parties' agreement, may give particular meaning to specific terms of the agreement, and may supplement or qualify the terms of the agreement.  A usage of trade applicable in the place in which part of the performance under the agreement is to occur may be so utilized as to that part of the performance.
(e)  Except as otherwise provided in subsection (f), the express terms of an agreement and any applicable course of performance, course of dealing, or usage of trade must be construed whenever reasonable as consistent with each other.  If such a construction is unreasonable:
(1) express terms prevail over course of performance,     course of dealing, and usage of trade;
(2) course of performance prevails over course of     dealing and usage of trade; and
(3) course of dealing prevails over usage of trade.
(f)  Subject to Section 2-209, a course of performance is relevant to show a waiver or modification of any term inconsistent with the course of performance.
(g)  Evidence of a relevant usage of trade offered by one party is not admissible unless that party has given the other party notice that the court finds sufficient to prevent unfair surprise to the other party.

(810 ILCS 5/1-305)
Sec. 1-305. Remedies to be liberally administered.
(a)  The remedies provided by the Uniform Commercial Code must be liberally administered to the end that the aggrieved party may be put in as good a position as if the other party had fully performed but neither consequential or special damages nor penal damages may be had except as specifically provided in the Uniform Commercial Code or by other rule of law.

A document in due form purporting to be a bill of lading, policy or certificate of insurance, official weigher's or inspector's certificate, consular invoice, or any other document authorized or required by the contract to be issued by a third party is prima facie evidence of its own authenticity and genuineness and of the facts stated in the document by the third party.

Sec. 1-309. Option to accelerate at will.   A term providing that one party or that party's successor in interest may accelerate payment or performance or require collateral or additional collateral "at will" or when the party "deems itself insecure", or words of similar import, means that the party has power to do so only if that party in good faith believes that the prospect of payment or performance is impaired.  The burden of establishing lack of good faith is on the party against which the power has been exercised.
