                          REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT, dated as of May 22, 2000 by and between TRC
COMPANIES, INC., a Delaware corporation ("TRC") and John V. Lowney, individually
and as Trustee of the John V. Lowney 1990 Revocable Trust dated August 27, 1990,
Ron L. Helm, Ronald A. Massone, Stason I. Foster, C. Barry Butler, Thomas C.
Benson, Jr., Belinda P. Blackie, Thomas F. McCloskey and Peter M. Langtry (each
such individual a "Stockholder" and collectively, the "Stockholders").

     TRC and the Stockholders have entered into a Stock Purchase Agreement (the
"Agreement") dated May 22, 2000, pursuant to which, among other things, the
Stockholders will be entitled to receive, subject to the terms and conditions of
the Agreement shares of the common stock, $.10 par value, of TRC, (the "TRC
Shares") as well as Common Stock Purchase Warrants (the "Warrants") to purchase
TRC shares.

     In connection with the foregoing, TRC hereby grants to the Stockholders
certain registration and other rights with respect to the TRC Shares.

     Accordingly, the parties hereto agree as follows:

     1. REGISTRATION. (a) If TRC acts to register any of its common stock under
the Securities Act of 1933 (the "Act") (including for this purpose a
registration effected by TRC for stockholders other than the Stockholders) on or
before (i) one year after the Closing Date, or (ii) with respect to TRC Shares
purchased upon exercise of the Warrants, one year after a majority of the
Warrants are exercised, and the registration form to be used may be used without
substantial modification for the registration of the TRC Shares, TRC will give
prompt written notice to John V. Lowney as agent for the Stockholders (the
"Agent"), and will include in such registration statement all or any portion of
the TRC Shares which the Stockholders elect to sell in such registration,
provided that TRC shall not be obliged to, and shall not, include any TRC Shares
in more than one effective registration statement during the periods noted as
(i) and (ii) above. Furthermore, TRC shall not be obligated to and shall not
include any TRC Shares unless (a) the holders of at least 25,000 of the TRC
Shares subject to registration shall have requested registration, and (b) TRC's
underwriter shall determine that the inclusion of such TRC Shares would not
adversely affect TRC's offering. If TRC's underwriter determines that such TRC
Shares would adversely affect TRC's offering, the Sellers (as defined below)
will reduce the number of TRC Shares they propose to sell (pro rata) as
requested by TRC's underwriter, provided if the reduction is of twenty (20) or
more percent of the TRC Shares requested for registration, then the Stockholders
shall be entitled to participate in one additional registration in accordance
with this Agreement, provided that under no circumstances will such right
continue beyond one year after the Closing Date or with respect to TRC Shares
purchased upon exercise of the Warrants one year after the majority of the
Warrants are exercised.

     Any request for inclusion in a proposed registration shall be made within
thirty (30) days of receipt by the Agent of written notice from TRC.

                                       1
<Page>

          (b) Each holder of TRC Shares who wishes to have his TRC Shares
registered (a "Seller") will furnish TRC with such appropriate information
relating to the holder as TRC reasonably requests in writing. Following the
effective date of the registration statement, TRC will, upon the request of a
Seller, promptly supply such number of prospectuses meeting the requirements of
the Act as may be reasonably requested by the Seller to permit Seller to make a
public offering of all TRC Shares of the Seller included in the registration
statement. TRC will use its best efforts to qualify the TRC Shares for sale in
such states as the Seller may reasonably designate; provided that in no event
will TRC be required to file a general consent to service of process.

               In the event of any underwritten public offering, TRC shall enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. TRC shall notify
each Seller at any time when a prospectus relating to the sale of such Seller's
securities is required to be delivered under the Act of the happening of any
event as a result of which such prospectus includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing. TRC shall cause all TRC Shares registered pursuant
to this Agreement to be listed on each securities exchange on which similar
securities issued by TRC are then listed. TRC shall provide a transfer agent and
registrar for all TRC Shares registered pursuant to this Agreement and CUSIP
number for all such TRC Shares, in each case not later than the effective date
of such registration.

          (c) TRC will indemnify and hold harmless each Seller and each
underwriter, within the meaning of the Act, who may purchase from or sell for a
Seller TRC Shares, from and against any and all losses, claims, damages and
liabilities caused by any untrue statement or alleged untrue statement of a
material fact contained in any registration statement under the Act or any
prospectus included in it required to be filed or furnished by reason of this
Agreement or caused by any omission or alleged omission to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by an untrue statement or alleged untrue statement or omission or alleged
omission based upon information furnished or required to be furnished in writing
to TRC by the Seller or underwriter expressly for use in the registration
statement, which indemnifications will include each person, if any, who controls
any such Seller or underwriter within the meaning of the Act; PROVIDED, HOWEVER,
that TRC will not indemnify any Seller or underwriter or controlling person with
regard to a requested registration statement unless the Seller or underwriter
agrees to indemnify TRC, its directors, each officer signing the registration
statement and each person, if any, who controls TRC within the meaning of the
Act from and against any and all losses, claims, damages, and liabilities caused
by any untrue statement or alleged untrue statement of a material fact contained
in any registration statement or any prospectus required to be filed or
furnished by reason of this Agreement or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading insofar as such losses,
claims, damages or liabilities are caused by any untrue statement or alleged
untrue statement or omission or alleged omission based upon information
furnished in writing to TRC by the Seller or underwriter expressly for use
therein.

                                       2
<Page>

          (d) All costs and expenses incident to the registration and
qualifications required by this Section shall be borne by TRC, except that
underwriting discounts attributable to the TRC Shares, any legal fees of counsel
for the Sellers, and the cost of qualifying the TRC Shares for sale in any
states other than the states in which the common stock to be registered by TRC
is to be qualified shall be borne by the Sellers.

          (e) TRC shall not be required to effect any registration of TRC Shares
if it shall deliver to the Stockholders requesting such registration an opinion
of counsel (which opinion and counsel shall be reasonably satisfactory to such
Stockholders) to the effect that the TRC Shares held by such Stockholders may be
sold in the public market without registration under the Securities Act and any
applicable state securities laws.

     2. RULE 144. TRC shall take all actions necessary to enable holders of TRC
Shares to sell such securities without registration under the Securities Act
within the exemptions provided by (a) Rule 144, or (b) any similar rule or
regulation hereafter adopted by the Securities and Exchange Commission
including, without limiting the generality of the foregoing, filing on a timely
basis all reports required to be filed by the Exchange Act. Upon the request of
the Stockholders, TRC will deliver to such holders a written statement as to
whether it has complied with such requirements.

     3. ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause TRC to include
the TRC Shares in a registration statement pursuant to this Agreement may be
assigned (but only with all related obligations) by a Stockholder to a
transferee or assignee of such securities that (i) is a Stockholder's family
member, trust for the benefit of a Stockholder, or a trust or foundation formed
by the Stockholder, or (ii) after such assignment or transfer, holds at least
25,000 TRC Shares (subject to appropriate adjustment for stock splits, stock
dividends, combinations and other recapitalizations), provided: (a) TRC is,
within a reasonable time after such transfer, furnished with written notice of
the name and address of such transferee or assignee and the securities with
respect to which such registration rights are being assigned; (b) such
transferee or assignee agrees in writing to be bound by and subject to the terms
and conditions of this Agreement; and (c) such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

     4. AMENDMENT AND MODIFICATION. This Agreement may be amended, modified or
supplemented only by written agreement of the party or parties against whom
enforcement of such amendment, modification or supplement is sought.

     5. NOTICES. Any notice or other communication required or permitted
hereunder shall be in writing and shall be delivered personally, by reputable

          (ii) As an addition to the Purchase Price, Buyer shall pay Seller,

for purposes of reviewing and resolving any disputes concerning the calculation
of the Earnout Payment. In the event that Seller notifies Buyer of a dispute ,
the undisputed portion of the Earnout Payment shall be paid to Seller on the due

arbitration to a mutually agreeable independent accountant. The cost of the
arbitration shall be shared equally by the parties, provided, however, that the
prevailing party in the arbitration shall be reimbursed for all costs and
expanses incurred in resolving the dispute. The determination by the arbitrator

                                       2

          (d) REGISTRATION. The TRC Shares deliverable hereunder will not be
registered and will bear a restrictive legend in substantially the following
form:

               "The Stock represented by this Certificate has not been
               registered under the Federal Securities Act of 1933, as amended,
               and may not be assigned, transferred or otherwise disposed of
               without an opinion of counsel satisfactory to the Company that an
               exemption under such Act is available therefor or that an
               applicable registration statement under such Act is effective
               with respect thereto. In addition, the stock has not been
               registered or qualified in accordance with the securities laws of
               any state and transfer may be made only in compliance with such
               laws."

          (e) Registration Rights. If, within one (1) year after the Closing
Date, Parent files a registration statement under the Securities Act of 1933, as
amended, or any successor statute then in effect, covering a public offering in
excess of $7,500,000 by Parent or any stockholder of Parent of shares of the
common stock of Parent other than a registration statement solely in connection
with an employee benefit plan, Buyer shall first so notify Seller of Parent's
intent to file a registration statement. Within sixty (60) days after giving
such notice to Seller, Seller may, by written notice to Parent, request that
Seller's shares be included in such registration statement. In such case and
with the giving of Seller's notice, Buyer shall use its best efforts to include
such shares in the registration statement and related underwriting arrangements.
No such effort need be made, however, if, in the reasonable opinion of counsel
for Parent, the disposition of such shares is exempt from applicable
registration requirements at that time. If the offering by Parent is
underwritten, any shares disposed of pursuant to this provision will be
underwritten by the same underwriter or underwriters on the same basis as other
shares included in the offering. In the event the managing underwriter or

Securities and Exchange Commission pursuant to the Securities Exchange Act of
1934, as amended (the "Exchange Act"), since December 31, 1998 (collectively,
the "SEC Reports"). The SEC Reports complied in all material respects with all
applicable requirements of the Exchange Act and, as of their respective filing
dates, did not contain any untrue statement of material fact or omit to state a
material fact necessary in order to make the statements made therein, in light
of the circumstances under which they were made, not misleading. The audited and
unaudited consolidated financial statements of Buyer included in the SEC Reports
have been prepared in accordance with generally accepted accounting principles
applied on a consistent basis (except as stated in the financial statements) and

as of the dates thereof and the results of their operations and changes in
financial position for the periods then ended, subject, in the case of the
unaudited financial statements, to normal year-end audit adjustments.

statements herein not misleading.

broker in connection with the transactions contemplated hereby.

     4.9 INVESTMENT. Buyer understands that the Company Shares to be acquired in
this Transaction have not and will not be registered under the Securities Act of
1933 or under any state securities laws, that no public offering is involved in
the offering and sale of the Company Shares, and Buyer is acquiring the Company
Shares solely for its own account for investment purposes and not with a view to
a distribution thereof.

     4.10 Tax Effect. The acquisition of the TRC Shares by Seller will be
treated as a nontaxable exchange of stock by Seller for federal income tax
purposes. Parent shall report the transaction for tax purposes in a manner
consistent with this tax position.

(except to the extent a Notice as hereinafter defined asserting a claim for

faith prior to such date to the party which made such representation or

                                       14
<Page>

warranty). The covenants and agreements contained herein to be performed or
complied with after the Closing shall survive the Closing and expire in
accordance with their terms.

     10.2 INDEMNIFICATION BY SELLER. From and after the Closing, Seller shall
indemnify and hold harmless Buyer from and against any and all demands, claims,
losses, liabilities, actions or causes of action, assessments, damages, fines,
taxes, penalties, costs and expenses (including, without limitation, interest,

asserted by Buyer against Seller or asserted by third parties) (collectively
"Losses") incurred or suffered by Buyer, and their affiliates, and their
respective officers, directors, employees, agents and representatives arising
out of, resulting from, or relating to (a) any breach by Seller of any of his
representations and warranties contained in this Agreement; or (b) any failure
by Seller to perform any of his respective covenants or agreements contained in
this Agreement. Notwithstanding any other provision of this Agreement, and
except as provided in the following sentence, the total aggregate liability of

warranties made by Buyer in this Agreement; (b) any failure by Buyer to perform
any of its covenants or agreements contained in this Agreement; or (c) the
business or operations of Company after the Closing, except to the extent
arising out of, resulting from or relating to any breach of any of the
representations and warranties and covenants of Seller under this Agreement or
the business or operations of Company prior to the Closing.

     10.4 PROCEDURE. (a) In the event that any party hereto shall sustain or
incur any Losses in respect of which indemnification may be sought by such party
pursuant to this Article 10, the party seeking such indemnification (the
"Indemnitee") shall assert a claim for indemnification by giving written notice
thereof (the "Notice") to the party (or parties) providing indemnification (the
"Indemnitor") within thirty (30) days after (i) receipt of written notice of
commencement of any third party litigation against such Indemnitee, (ii) receipt
by such Indemnitee of written notice of any third party claim pursuant to an
invoice, notice of claim or assessment against such Indemnitee, or (iii) such
Indemnitee becomes aware of the existence of any other event in respect of which
indemnification may be sought from the Indemnitor (including, without
limitation, any inaccuracy of any representation or warranty or breach of any
covenant). The Notice shall describe the claim and the specific facts and
circumstances in reasonable detail, and shall indicate the amount, if known, or
an estimate, if possible, of the Losses that have been or may be incurred or
suffered by such Indemnitee. The failure to timely deliver a Notice shall not
relieve the Indemnitor from the obligation to indemnify hereunder except to the
extent that the Indemnitor is prejudiced thereby. In case any third party claim,
action or proceeding (a "Claim") is brought against any Indemnitee, the
Indemnitor shall be entitled to assume the defense thereof, by written notice to
the Indemnitee of its intention to do so within 30 days after receipt of the
Notice. If the Indemnitor shall assume the defense of such Claim, without the
consent of the Indemnitee, which shall not be unreasonably withheld, the
Indemnitor shall not settle such Claim unless such settlement includes as an
unconditional term thereof the giving by the claimant or the plaintiff of a
release of the Indemnitee, satisfactory to the Indemnitee, from all liability
with respect to such Claim. Notwithstanding the assumption by the Indemnitor of
the defense of any Claim as provided in this subsection, the Indemnitee shall be
permitted to join in the defense of such Claim and to employ counsel at its own
expense; PROVIDED, HOWEVER, that if the defendants in any action shall include
both an Indemnitor and any Indemnitee, and such Indemnitee shall have reasonably
concluded that counsel selected by the Indemnitor has a conflict of interest
because of the availability of different or additional defenses to such
Indemnitee, such Indemnitee shall have the right to select separate counsel to
participate in the defense of such action on its behalf, at the expense of the
Indemnitor.

          (b) If the Indemnitor shall fail to notify the Indemnitee of its
desire to assume the defense of any such Claim within the prescribed period of
time, or shall notify the Indemnitee that it will not assume the defense of any
such Claim, then the Indemnitee may assume the defense of any such Claim, in
which event it may do so in such manner as it may deem appropriate, and the
Indemnitor shall be bound by any determinations made in

                                       15

<Page>

any litigation with respect to any Claim or any settlement thereof, provided
that any such determinations or settlement shall not affect the right of the
Indemnitor to dispute any claim for indemnification by the Indemnitee.

          (c) Amounts payable by the Indemnitor to the Indemnitee in respect of
any Losses for which such party is entitled to indemnification hereunder shall
be payable by the Indemnitor as incurred by the Indemnitee. In the event Seller
is obligated to pay Buyer pursuant to this Article 10, Seller may make such
payment by reducing the face amount of the Note by a corresponding amount.

     10.5 INVESTIGATIONS; WAIVERS. The survival periods and rights to
indemnification provided for in this Article shall remain in effect for the
period set forth in Section 10.1 above notwithstanding any investigation at any
time by or on behalf of any party hereto or any waiver by any party hereto of
any condition to such party's obligations to consummate the transactions
contemplated hereby.

11.      TERMINATION

     11.1 TERMINATION AND ABANDONMENT. This Agreement may be terminated and the
transactions contemplated by this Agreement may be abandoned at any time prior
to the Closing;

          (a) by mutual written consent of Buyer and Seller; or

          (b) by Buyer if the Buyer is not reasonably satisfied with the results
of its continuing due diligence regarding the Company; or

          (c) by Buyer, on the one hand, or Seller on the other hand, if the
Closing shall not have occurred on or before December 29, 2000; PROVIDED,
HOWEVER, that the right to terminate this Agreement under this Section 11.1(c)
shall not be available to any party whose failure to fulfill any obligations
under this Agreement had been the cause of, or resulted in, the failure of the
Closing to occur on or before such date; or

          (d) by Buyer, on the one hand, or Seller on the other hand, if any
court of competent jurisdiction shall have issued an order, decree or ruling or
taken any other action restraining, enjoining or otherwise prohibiting the
transactions contemplated under this Agreement and such order, decree, ruling or
other action shall have become final and nonappealable.

     11.2 EFFECT OF TERMINATION. In the event of the termination of this
Agreement pursuant to Section 11.1, this Agreement shall forthwith become void,
and (except as provided in Section 11.3) there shall be no liability or
obligation on the part of any party hereto.

     11.3 FEES AND EXPENSES. Whether or not the transactions contemplated by
this Agreement are consummated, each of the parties hereto shall pay its own
expenses incurred in connection with the transactions contemplated hereby,
including taxes and legal, accounting and other fees. Notwithstanding the
provisions of Section 11.2, if this Agreement is terminated by Seller, on the
one hand, or Buyer, on the other hand, by reason of a breach by the other of
this Agreement, in addition to any other remedy available at law or in equity,
the terminating party shall be reimbursed by the breaching party for all
reasonable out-of-pocket costs and expenses incurred by the terminating party in
connection with the transactions contemplated by this Agreement.

12.      MISCELLANEOUS

     12.1 SPECIFIC PERFORMANCE. Seller, on the one hand, and Buyer, on the other
hand, acknowledge that the other will be irreparably harmed and will have no
adequate remedy at law if such party fails to perform any of its obligations
under this Agreement. It is accordingly agreed that, in addition to any other
remedies which may be available, the Parties shall have the right to obtain
injunctive relief to restrain a breach or threatened breach of, or otherwise
obtain specific performance of, covenants and other agreements of the other
party contained in this Agreement.

                                       16

     12.2 WAIVERS. No action taken pursuant to this Agreement, including any
investigation by or on behalf of any party hereto, shall be deemed to constitute
a waiver by the party taking such action of compliance with any representation,
warranty, covenant or agreement contained herein. The waiver by any party hereto
of any condition or of a breach of any provision of this Agreement shall not
operate or be construed as a waiver of any other condition or other breach. The
waiver by any party of any of the conditions precedent to its obligations under
this Agreement shall not preclude it from seeking redress for breach of this
Agreement other than with respect to the condition so waived.

     12.3 NOTICES. All notices, requests, demands, applications, and other
communications which are required to be or may be given under this Agreement
