This article is meant only to posit the question above in relation solely to an existing Master Service Agreement (“MSA”). For a very good discussion of the Parol Evidence Rule please see Scott Unger’s article What Is The Parol Evidence Rule? Unger covers all the bases in his article. He provides the pertinent citations where the court explains the purpose behind the rule and he also cites case law discussing the policy concerns supporting the rule.
"The Parol Evidence Rule is a substantive rule which states that whenever contractual intent is sought to be ascertained from among several expressions of agreement by the parties, an earlier tentative agreement will be rejected in favor of a later expression that is final."
Or more succinctly
"the final agreement made by the parties supersedes any terms discussed in earlier negotiations"
Unger also points out that a good draftsman should always include a “merger clause” in the contract. This is usually a clause found near the end of a contract, probably in a miscellaneous section, simply stating that the agreement is the final and complete expression of the parties to the agreement. It is there to aid the court. What should also be found in that merger clause is a statement allowing for modifications to the contract. The language should read something similar to the following:
“This Agreement may be modified only by a writing signed by both parties.”
Let’s now consider the question above in the title of this posting. When asked to make an adjustment to the MSA, one automatically thinks of an amendment or perhaps a Statement of Work (“SOW”) if that is how changes are contemplated. A change can also be easily accomplished through a Project Change Request (“PCR”) form if such a form was contemplated in the initial MSA and suits the desired change. These are all standard ways to change the original MSA. However there are times when your client requests a change be accomplished through a Side Letter. And so the question we must ask is, “Why?” This is of course a red flag to the attorney.
First you must assure yourself that there is no fraud involved. At the slightest hint of any fraud the attorney must stop at once. The next steps are quite involved and I direct you to the Model Code of Professional Responsibility. I am not an expert in this area, however I did come across a very interesting article by Boris Feldman entitled WHAT TO DO WHEN YOU FIND THE SIDE LETTER: GUIDELINES FOR CEO’S, CFO’S, AND AUDIT COMMITTEE MEMBERS IN INVESTIGATING ACCOUNTING FRAUD. Feldman lays out a step-by-step approach which could be very helpful.
So absent fraud, the question remains “Why a Side Letter”. I do not think there is a definitive answer to this question. In my experience it could be that business people are more comfortable with a side letter. It could be the “that is the way we do business” mentality. There could be a distrust of lawyers and contracts. Also the lawyers are usually seen as placing roadblocks in front of the deal and so for expediency sake the business folks prefer a letter. In their minds it is quicker and easier. Of course there is the ever popular notion that the cost would be prohibitive. A more formalized document just looks more costly.
One’s knee jerk response might be that the Parol Evidence Rule prevents the introduction of such a Side Letter in the event that a dispute regarding the Side Letter finds itself in the courts. But as Unger correctly points out, the exclusion of all evidence of discussions or agreements purporting to change the existing agreement pertains to prior writings and expressions. I also have seen that the exclusion applies to all prior and contemporaneous writings. In the question I posit above I state that the MSA is an existing agreement; and therefore, the Side Letter contemplated is a subsequent writing. The mere fact that the date of the letter is later than the effective date of the MSA should be sufficient to allow the Side Letter into evidence to prove the modification. However may I suggest the following:
• First and foremost assure yourself that no fraud is involved in the request.
• Absent fraud, then insert an “incorporation by reference” clause into the contract. This should allow the multitude of protections existing in the MSA to be applicable to the matter discussed in the Side Letter. It could be as simple as “This letter is hereby annexed to and made a part of the Agreement specified above.”
• Insert an Acknowledgement at the end of the letter after the signature block. I usually use the following language, “Please acknowledge your acceptance of the above terms by signing and dating this letter in the spaces provided below and returning a signed original to me at the address as provided above.” This helps us meet the “…may be modified only by a writing signed by both parties” language that should be found in the merger clause.
I’d like to know what you think. Have you encountered this type of request? Does the incorporation by reference and the use on an acknowledgement suffice? Is there more that needs to be inserted into the Side Letter? Should we simply say “no” to any Side Letter?
