| |  | | the legal validity of such conversions and mergers.  Although not |  | immune from variation in the partnership agreement, noncompliance |  | with the requirements of Article 9 in effecting a conversion or |  | merger is to deny that "safe harbor" validity to the transaction. |  | In this regard, Sections 903(b) and 905(c)(2) require that the |  | conversion or merger of a limited partnership be approved by all of |  | the partners, notwithstanding a contrary provision in the limited |  | partnership agreement.  Thus, in effect, the agreement can not vary |  | the voting requirement without sacrificing the benefits of the |  | "safe harbor." |

 | 
 
 
 |  | |  | 1.__Law and equity.__Unless displaced by particular provisions |  | of this chapter, the principles of law and equity supplement this |  | chapter. | 
 | 
 
 
 |  | |  | 2.__Interest rate.__If an obligation to pay interest arises |  | under this chapter and the rate is not specified, the rate is |  | that specified in Title 14, section 1602-B. |

 | 
 
 
 |  | |  | The principles of law and equity supplement RUPA unless |  | displaced by a particular provision of the Act.  This broad |  | statement combines the separate rules contained in UPA Sections |  | 4(2), 4(3), and 5.  These supplementary principles encompass not |  | only the law of agency and estoppel and the law merchant |  | mentioned in the UPA, but all of the other principles listed in |  | UCC Section 1103: the law relative to capacity to contract, |  | fraud, misrepresentation, duress, coercion, mistake, bankruptcy, |  | and other common law validating or invalidating causes, such as |  | unconscionability.  No substantive change from either the UPA or |  | the UCC is intended. | 
 | 
 
 
 |  | |  | It was thought unnecessary to repeat the UPA Section 4(1) |  | admonition that statutes in derogation of the common law are not |  | to be strictly construed.  This principle is now so well |  | established that it is not necessary to so state in the Act.  No |  | change in the law is intended.  See the Comment to RUPA Section |  | 1101. | 
 | 
 
 
 |  | |  | Subsection (b) is new.  It is based on the definition of |  | "interest" in Section 1482(5) of the Georgia act and establishes |  | the applicable rate of interest in the absence of an agreement |  | among the partners.  Adopting States can select the State's legal |  | rate of interest or other statutory interest rate, such as the |  | rate for judgments. |
