From 1976 to 1979, James H. Porter was vice-president and chief scientist of Energy Resources Corporation, Inc. (ERGO). On October 5, 1979, he resigned and organized Energy & Environmental Engineering, Inc. (EEE). The first business EEE undertook was a research project, to be done in collaboration with Howard University, for the United States Department of Energy concerning a *297method of burning high sulfur coal which would produce little air pollution. ERGO complains that Porter diverted a corporate opportunity, violated his employment agreement with ERGO and misappropriated trade secrets. A Superior Court judge sitting without a jury heard the case and entered judgment for the defendants.
We have the benefit of excellent findings of fact by the judge. Mass.R.Civ.P. 52(a), 365 Mass. 816 (1974). On those findings we rely for the factual setting of the case, with some fleshing out on the basis of undisputed matter in the record.
ERGO is a science and engineering company, located in Cambridge, which provides products and services in energy and environmental fields. Among its areas of investigation was staged fluidized bed combustion of coal. Ry that process, coal mixed with limestone could be burned so as to capture sulfur as a solid, rather than allowing it to escape into the atmosphere as a gas. To the end of developing a commercially efficient coal-fired furnace which harnessed that process, ERGO operated a fluidized bed combustor pilot plant and a full-scale fluid bed combustor test facility.
Porter had come to ERGO from the Massachusetts Institute of Technology, from which he held a doctoral degree and where he had been an associate professor in the department of chemical engineering. Fluidized bed combustion was a subject to which Porter had given attention at M.I.T. and about which he had written as early as 1963. At ERGO, research and development concerning application of the fluidized bed combustion process was under Porter’s general direction. As to royalties earned by ERGO from his inventions, Porter, under his employment agreement, was to receive 18% in addition to his annual salary (which was $52,000 in 1979).
In December, 1977, Porter went to Washington, D.G., to deliver a paper on fluidized bed combustion at a fifth annual meeting on that subject sponsored by the United States Environmental Protection Agency and the Department of Energy (DOE). While in Washington Porter looked up two *298colleagues at Howard University, Professors Cannon and Jackson, with whom he had been earlier acquainted. Cannon is chairman of the department of chemical engineering at Howard and Jackson is director of its fossil fuel laboratory.
This encounter led in due course to a joint proposal to DOE by Howard and ERGO for a development grant involving staged fluidized bed combustion of coal. Jackson had told Porter that DOE would be favorably disposed to a proposal from a “minority institution.” Howard, traditionally, has a black student body, and Cannon and Jackson are black. So is Porter. Howard was to be the primary applicant and ERGO would be the subcontractor. ERCO’s participation was approved by other executives of ERGO. During the first five months of 1979, Gannon, Jackson and Porter worked on the submission to DOE; Porter wrote most of the technical section. The draft proposal listed ERGO as a proposed subcontractor and included biographical information about ERGO personnel, notably, of course, about Porter.
In early May, 1979, during the course of a ride from Washington National Airport to DOE, Jackson advised Porter of a change of heart about working with ERGO. Jackson had become apprehensive that ERGO would claim the entire enterprise as its idea and that because “we are just little black people at a black university everybody was going to believe them.” Moreover, Jackson said, he didn’t want to be a part of something that might be seen as “blacks serving as sort of fronts for white firms getting minority money.” Finally, he thought that in the long run more money would flow from DOE if there were a minority subcontractor in the picture. Porter attempted to persuade Jackson to continue to work with ERGO.
During the conversation at DOE which followed, Jackson broached the subject of dealing with a subcontractor other than ERGO and was told by a DOE official that the key man was Porter, whether he was at ERGO or elsewhere . Cannon and Jackson came up to Cambridge a week *299later to see Porter at M.I.T. and suggested that, if he were to form his own company, they would be pleased to substitute it for ERGO in the proposal to DOE. Porter agreed to do so. Cannon and Jackson deleted references to ERGO and substituted EEE, a corporation to be formed by Porter. Thereafter, although he continued to work at ERGO, Porter cut himself off from the Howard submission to DOE. “I knew I was in a ticklish position, sought advice of counsel and decided it best I just not do anything on that proposal.”
About three weeks later, Richard H. Rosen, the president of ERGO, Robert S. Davis, an executive vice-president, and Porter met for a routine review of pending ERGO projects. At that meeting Rosen asked Porter, “How about the Howard proposal?” Porter responded, “We’re not going to get that.” Rosen and Davis made no further inquiry and went on to the next item of business. Davis asked Porter about the Howard proposal on a later occasion and, once again, was told, without further elaboration, that ERGO wasn’t going to get a subcontract from Howard.
Toward the end of September or the beginning of October, 1979, DOE awarded a grant to Howard and on or about October 5, 1979, Porter resigned his offices at ERGO on one day’s notice. He told Davis and Rosen that his reason for leaving was to organize a corporation which would work in the area of computerized cars. Rosen, still unaware of Porter’s participation in the Howard project, hired Porter as an independent consultant to ERGO for a period of sixty days.
1. The corporate opportunity. None of the parties debates that exploitation of the fluidized bed combustion process was squarely within ERCO’s corporate activity and that, without more, an officer of ERGO had a fiduciary duty not to divert that opportunity for his own benefit. See Durfee v. Durfee & Canning, Inc., 323 Mass. 187, 198-199 (1948); BBF, Inc. v. Germanium Power Devices Corp., 13 Mass. App. Ct. 166, 172 (1982), and cases cited. Indeed, Porter used his time as an employee of ERGO and the time of other employees of ERGO, as well as certain graphics, *300in preparing a draft of the submission to DOE which ultimately reeled in a grant. Contrast Lincoln Stores, Inc. v. Grant, 309 Mass. 417, 421-422 (1941); Black v. Parker Mfg. Co., 329 Mass. 105, 112-113 (1952).
Porter’s defense is that the staged fluidized bed combustion project with Howard ceased being a corporate opportunity for ERGO when Jackson refused to deal with ERGO. When a corporation is unable to avail itself of an opportunity, its employee, officer or director is free to exploit it. Miller v. Miller, 301 Minn. 207, 225 (1974). 3 Fletcher, Cyclopedia of the Law of Private Corporations § 862.1 (rev. perm. ed. 1975).2 It was a defense which the trial judge thought convincing: “[N]o amount of persuasion,” he wrote, “could alter Dr. Jackson’s resolve that the subcontractor be a minority concern.” Porter was not to be asked for “performance of fiduciary duty even to the point of futility.” The difficulty with the judge’s reasoning is that the unalter ability of Jackson’s resolve can by no means be certain so long as Porter, by keeping Jackson’s position and his reasons for it a secret, never afforded ERGO a chance to test it. Had Porter told ERGO about Howard University’s desire (as manifested by Jackson) to deal with a subcontractor controlled by persons who were black, the matter might have taken a variety of turns. Other officers of ERGO might have persuaded Jackson and Cannon — or others at Howard — that the status of Porter with ERGO was such that their unease about ERGO was not warranted. It might have been possible to organize a corporation in which Porter had a majority position and ERGO had a minority position. These are but two of many possibilities.
For the reason that the firmness of a refusal to deal cannot be adequately tested by the corporate executive alone, it has not been favored as a defense unless the refusal has first been disclosed to the corporation. Without full disclosure it is too difficult to verify the unwillingness to deal and too *301easy for the executive to induce the unwillingness. Note, Corporate Opportunity, 74 Harv.L.Rev. 765, 773 (1961). See Brudney & Clark, A New Look at Corporate Opportunities, 94 Harv.L.Rev. 997, 1021 (1981). If the refusal to deal is shrouded in secrecy, it is too likely that the tempted officer will find himself in the position of Fielding’s “fair creature” of whom he wrote, “[He] would have ravished her, if she had not, by a timely compliance, prevented him.”3
Although the defense of a refusal to deal has not been squarely confronted in Massachusetts cases, similar defenses of corporate inability to exploit an opportunity have had a cool reception. In Durfee v. Durfee & Canning, Inc., 323 Mass, at 200-202, the credit weakness of the corporation did not permit Canning, who was a director and principal officer, to turn to his own account the purchase of gasoline which would have been advantageous to the corporation. Production Mach. Co. v. Howe, 327 Mass. 372, 375-378 (1951), required disclosure of the availability of a line of business that, although new to the corporation, was within its manufacturing capacity. “Breach of the duty [to protect the interests of the corporation] could be found although no corruption, dishonesty, or bad faith was involved.” Id. at 378. In Cain v. Cain, 3 Mass. App. Ct. 467, 476-477 (1975), we required the defendant to inform the corporation of which he was a director and treasurer that the loss of certain business was imminent.
A case closer on its facts to that at bar was Kelly v. 74 & 76 W. Tremont Ave. Corp., 4 Misc. 2d 533 (N.Y. Sup. Ct. 1956), in which the executive, defending a diversion of a corporate opportunity, claimed that the seller would not have sold certain controlling stock to his corporation at the same price available to him. Commenting that, at the least, the executive was required to make full and frank disclosure of this refusal to deal, the court wrote: “If Jameson [the seller], in no event, would change his mind, and Gold-*302stein [the buyer] made full disclosure, there would have been time enough to have permitted Goldstein’s purchase of the stock for himself and his favored colleagues.” Id. at 537. See also Patient Care Servs., S.C. v. Segal, 32 Ill. App. 3d 1021, 1031 (1975); Ellzeyy. Fyr-Pruf, Inc., 376 So.2d 1328 (Miss. 1979). We conclude that before a person invokes refusal to deal as a reason for diverting a corporate opportunity he must unambiguously disclose that refusal to the corporation to which he owes a duty, together with a fair statement of the reasons for that refusal. Porter’s statement, “We’re not going to get that,” fell far short of that standard. Indeed, Porter went beyond nondisclosure. He acted secretively and even on the occasion of his departure from ERGO masked his true reason for leaving.
2. Misappropriation of trade secrets. It might be thought that the questions of misappropriation of trade secrets are subsumed in the corporate opportunity question; that is, whatever damages flow from diversion of the corporate opportunity would be the same as from misappropriation of trade secrets concerning staged fluidized bed combustion, if there were any. Upon closer examination, the diversion of the corporate opportunity related not to fluidized bed combustion but to joining with Howard to obtain a development grant for the process. The misappropriation question retains significance.
The trial judge found that: “fluidized bed technology and concepts have been common knowledge in the professional and scientific community for a number of years; . . . that staged or multi-staged fluidized beds have been in existence for at least [twenty] years and are illustrated and discussed in technical literature . . .;” and that such nuances as ERGO had developed through Porter’s work had not been closely guarded. There was support in the record for these findings and we are far from a conviction that a mistake has been made. New England Canteen Serv., Inc. v. Ashley, 372 Mass. 671, 675 (1977). On the basis of these findings the judge correctly ruled that Porter was not to be broadly restrained from putting to use the product of his *303general knowledge, experience and skill in the fluidized bed combustion field. J. T. Healy & Son v. James A. Murphy & Son, 357 Mass. 728, 736 (1970). Jet Spray Cooler, Inc. v. Crampton, 361 Mass. 835, 840 (1972). Jet Spray Cooler, Inc. v. Crampton, 377 Mass. 159, 165 (1979). Chomerics, Inc. v. Ehrreich, 12 Mass. App. Ct. 1, 6 (1981). See also Manos v. Melton, 358 Mich. 500 (1960), a case close on its facts to that at bar.
3. Other issues. Whether Porter was in breach of his employment agreement is subsumed in the resolution of the previous issues, i.e., the diversion of the corporate opportunity is perforce a breach of a provision in the employment agreement that the employee will “diligently perform all duties of his . . . employment and . . . devote his full time, skill, energy and ability for the promotion of the business of the Company.” The same damage results, whether seen as flowing from violation of Porter’s fiduciary duty or violation of the agreement. Since no misappropriation of trade secrets was found, Porter cannot be in breach of that portion of the agreement which required him not to divulge confidential information.
ERCO’s claim under G. L. c. 93A is governed by Newton v. Moffie, 13 Mass. App. Ct. 462, 469 (1982), and is, therefore, without merit.
The judgment is reversed and the case is remanded to the Superior Court for assessment of damages based on a computation of EEE’s net profits from the DOE grant. The court should disallow as deductions from EEE’s gross profits fees and expenses incident to the DOE project which ERGO would not have had to incur, and distributions to Porter in excess of $52,000 per year. Nondeductible expenses shall include, but shall not be limited to, EEE’s legal fees in connection with its incorporation and this litigation.
So ordered.
The inability asserted is often a lack of financial capacity by the corporation. See, e.g., Durfee v. Durfee & Canning, Inc., 323 Mass, at 202.
