Attention:  Mr. Kent P. Ainsworth
            Executive Vice President
            and Chief Financial Officer


Dear Mr. Ainsworth:

          We understand that URS Corporation, a Delaware corporation ("URS"), or
one or its subsidiaries will acquire (the "Acquisition") all of the issued and
outstanding shares of Dames & Moore Group, a Delaware corporation (the
"Company").  As we understand the Acquisition, URS, together with its wholly-
owned subsidiary ("Merger Sub") will, pursuant to an Agreement and Plan of
Merger to be entered into with the Company (the "Acquisition Agreement"), offer
to acquire through a tender offer (the "Tender Offer") all of the issued and
outstanding shares of the Company's capital stock (the "Company Stock") for a
price of $16 per share, in cash.  The Acquisition will be financed through (i) a
cash equity investment by Richard C. Blum & Associates, L.P. ("RCBA") in URS of
not less than $100 million (the "Equity Contribution"), (ii) URS" issuance and
sale on the date on which the Tender Offer is consummated (the "Closing Date")
of senior subordinated increasing rate notes in an aggregate principal amount of
$200 million (the "Bridge Notes") having substantially the terms set forth in
Exhibit A hereto (such Exhibit, together with Exhibit B hereto, collectively,
the "Term Sheet") (unless the Permanent Financing (as defined below) has been
consummated in connection with the Acquisition), and (iii) an aggregate amount
of $550 million in bank borrowings comprised of $450 million in term loans and
$100 million in a revolving credit facility (the "Senior Bank Financing") with
Wells Fargo Bank, N.A. ("Wells Fargo") and certain other financial institutions.
As promptly as reasonably practicable after the closing of the Tender Offer,
Merger Sub will consummate a merger with the Company in which the Company will
be the surviving corporation and a wholly-owned subsidiary of URS (the
"Merger").  As soon as reasonably practicable after the consummation of the
Acquisition, URS will issue $200 million in long-term, fixed-rate, unsecured,
subordinated debt securities (the "Permanent Financing"), the cash proceeds of
which will be used to redeem the Bridge Notes or any outstanding Rollover Notes
(as defined herein).  If by the maturity date of the 

 
                                       2


Bridge Notes the Permanent Financing shall not have been issued, or shall not
have been issued in an amount sufficient to repay the principal of and accrued
and unpaid interest on the Bridge Notes, such unpaid principal will be satisfied
by the issuance to the holders of the Bridge Notes of debt securities of URS
having substantially those terms set forth in Exhibit B hereto (the "Rollover
Notes"). The Acquisition, the refinancing of certain existing debt of URS and
the Company, and the debt and equity financings thereof described above are
hereinafter referred to as the "Transaction".

          Based upon and subject to the foregoing and as further provided below
and in the Term Sheet, Morgan Stanley & Co. Incorporated ("MS") hereby commits
to purchase, or to cause one or more of its affiliates to purchase, on the
Closing Date up to $200 million of the Bridge Notes, in each case on the terms
and subject to the conditions set forth in the Term Sheet.  The term
"Purchasers" as used in this Commitment Letter and the Term Sheet shall mean MS,
one or more of MS's assignees and the financial institutions referred to in the
succeeding paragraph who actually purchase or undertake the commitment to
purchase the Bridge Notes referred to herein.  Unless the Purchasers' commitment
hereunder shall have been terminated in accordance with the terms of this
Commitment Letter, the Purchasers shall have the exclusive right to purchase
Bridge Notes or otherwise provide other bridge or interim financing in
connection with the Acquisition and neither you nor the Company shall, directly
or indirectly, enter into any bridge or other interim financing in connection
with the Acquisition except for the sale of Bridge Notes to the Purchasers.  You
hereby represent and covenant that based on your review and analysis, to the
best of your knowledge, (a) all information other than Projections (as defined
below) that has been or is hereafter made available to the Purchasers by you or
your representatives, advisors or affiliates in connection with the Transaction
(the "Information") has been reviewed and analyzed by you in connection with the
performance of your own due diligence and is, or in the case of Information made
available after the date hereof will be, complete and correct in all material
respects and does not and will not contain any untrue statement of a material
fact or omit to state a material fact known to you and necessary to make the
statements contained therein, in the light of the circumstances under which such
statements were or are made, not misleading and (b) all financial projections
concerning the Company that have been or are hereafter made available to the
Purchasers by you or your representatives, advisors or affiliates in connection
with the Transactions (the "Projections") have been or, in the case of
Projections made available after the date hereof, will be prepared in good faith
based upon reasonable assumptions (it being understood that the Projections are
subject to significant uncertainties and contingencies, many of which are beyond
your control, and that no assurance can be given that such Projections will be
realized).  You agree to supplement the Information and the Projections prior to
the termination of the Purchasers' commitment hereunder so that the
representation and warranty made in the preceding sentence is correct as of such
date.  The Purchasers will be using and relying on the Information and the
Projections.  The representations and covenants contained in this paragraph
shall remain effective until a definitive financing agreement with respect to
the Bridge Notes (the "Financing Documentation") is executed and thereafter the
disclosure representations contained herein shall 

 
                                       3

be terminated and of no further force and effect. Those matters that are not
covered or made clear herein or in the Term Sheet are subject to mutual
agreement of the parties. This Commitment Letter may not be amended or modified,
and no waiver will be effective, except by a writing duly executed by the
parties hereto. Fees payable to MS in connection with the Bridge Notes and the
Permanent Financing shall be payable as described in the fee letter (the "Fee
Letter") executed simultaneously herewith.

          MS reserves the right, prior to or after execution of the definitive
documentation for the Bridge Notes, to syndicate all or part of its commitment
for the Bridge Notes to one or more financial institutions that will become
parties to such definitive documentation pursuant to a syndication to be managed
by MS, and the commitment of MS hereunder shall be reduced as and when binding
commitments are received from such financial institutions; provided that (i) MS
shall consult with you in identifying such financial institutions and (ii) the
financial ability of any such institution to purchase the respective Bridge
Notes shall be reasonably acceptable to you.  MS may commence syndication
efforts promptly after the execution of this letter by you and you agree
actively to assist MS in achieving a syndication that is satisfactory to you and
MS.  Such syndication will be accomplished by a variety of means, including
direct contact during the syndication between senior management and advisors of
URS and the proposed syndicate members.  To assist MS in its syndication
efforts, you hereby agree (a) to provide and cause your advisors to provide MS
and the other syndicate members upon request with all information reasonably
deemed necessary by MS to complete syndication, including but not limited to
information and evaluations prepared by you and your advisors or on your behalf
relating to the Transaction, (b) to assist MS upon request in the preparation of
an Information Memorandum to be used in connection with the syndication of the
Bridge Notes and (c) to make available your senior officers and representatives,
in each case from time to time and upon reasonable notice to attend and make
presentations regarding the business and prospects of URS at a meeting or
meetings of lenders or prospective lenders.  In addition, you agree that, except
for the Senior Bank Financing and any refinancing, renewal or increase thereof,
no financing for you or any of your subsidiaries or affiliates shall be
syndicated, privately placed or publicly offered to the extent that such
financing could have an adverse effect on the syndication of the Bridge Notes
(it being understood that lease financings in the ordinary course of business
shall not be prohibited by this sentence).

          By your execution of this Commitment Letter, you hereby retain MS to
act as exclusive agent or sole underwriter for the Permanent Financing
(including any other financing that will refinance the Bridge Notes or Rollover
Notes or other debt financing the proceeds of which are used to fund in part the
Acquisition (excluding the Senior Bank Financing)), and MS agrees to act as such
exclusive agent or sole underwriter pursuant to the terms of an underwriting or
placement agreement and related transaction documents (collectively, the
"Purchase Agreement"). Neither you nor the Company shall, directly or indirectly
(except through MS or as otherwise approved by MS), sell or offer to sell any
debt security for cash or property in 

 
                                       4

connection with the financing of the Acquisition or any related refinancings
(other than (a) loans incurred under and pursuant to the Senior Bank Facility,
(b) the Equity Contribution and (c) the Bridge Notes) during the term of our
engagement for the Permanent Financing. Notwithstanding anything to the contrary
contained herein or any oral representations or assurances previously or
subsequently made by the parties, this Commitment Letter is not intended to be
and does not constitute a commitment or obligation by MS to act as an
underwriter or placement agent in connection with any offering or sale of
securities (other than MS's obligation to purchase the Bridge Notes as provided
herein); and no liability or obligation on the part of MS to proceed with or
participate in an offering of securities by you or the Company shall be created
or exist unless or until MS has executed and delivered a Purchase Agreement and
then only in accordance with the terms and conditions set forth therein (other
than MS's obligation to purchase the Bridge Notes as provided herein). The
engagement of MS hereunder for the Permanent Financing may be terminated (i) by
MS at any time, or (ii) by you after the earliest to occur of (1) the
termination of the Acquisition Agreement in accordance with its terms, (2) the
use of the proceeds of the sale of the Permanent Financing contemplated by this
Commitment Letter or (3) 18 months after the consummation of the Acquisition, by
prior written notice thereof to MS; provided, however, that any fees earned
prior to the date of such termination shall survive such termination.

          Upon request from MS, URS shall take reasonable steps to assist MS in
preparing an offering document and shall participate in due diligence and
marketing efforts (including a road show) so that, as soon as reasonably
practicable after such request, the Permanent Financing can be completed on such
terms and conditions as are customary for similar high-yield financings in light
of the then-prevailing market conditions.

          In partial consideration for our commitment hereunder URS hereby
agrees to indemnify and hold harmless the Purchasers, each of the members or
shareholders or other investors or holders of interests in, or other transferees
of the Purchasers (collectively, "Additional Investors"), any affiliates of the
Purchasers and the Additional Investors, and each other person, if any,
controlling the Purchasers or any Additional Investors and any of their
respective affiliates, and any of the directors, officers, agents and employees
of any of the foregoing (each, an "Indemnified Person") from and against any
losses, claims, damages or liabilities related to, arising out of or in
connection with the matters that are the subject of the commitment made
hereunder (including, without limitation, any use made or proposed to be made by
URS of the proceeds from the Transaction) or in connection with any aspect of
the Transaction (collectively, the "Subject Matter"), and will reimburse any
Indemnified Person for all expenses (including fees and expenses of counsel) as
they are incurred in connection with investigating, preparing, pursuing or
defending any action, claim, suit, investigation or proceeding related to,
arising out of or in connection with the Subject Matter, whether or not pending
or threatened and whether or not such action, claim, suit or proceeding is
brought by you, your subsidiaries, creditors or any Indemnified Person, or any
Indemnified Person is otherwise a party thereto, and whether or not the
Transaction is consummated.  URS will not, however, be responsible for any

 
                                       5

losses, claims, damages or liabilities (or expenses relating thereto) that are
finally judicially determined to have resulted from the bad faith, willful
misconduct or gross negligence of any Indemnified Person. URS also agrees that
no Indemnified Person shall have any liability (whether direct or indirect, in
contract or tort or otherwise) to URS for or in connection with the Subject
Matter, except for any such liability for losses, claims, damages or liabilities
incurred by you that are finally judicially determined to have resulted from the
bad faith, willful misconduct or gross negligence of such Indemnified Person and
except for direct damages (but not consequential or punitive damages) incurred
by you that are finally judicially determined to have resulted from the
Purchasers' wrongful failure to purchase the Bridge Notes.

          URS will not, without the prior written consent of the Purchasers,
settle, compromise, consent to the entry of any judgment in or otherwise seek to
terminate any action, claim, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not any Indemnified Person
is a party thereto) unless such settlement, compromise, consent or termination
includes a full and unconditional release of each Indemnified Person from any
liabilities arising out of such action, claim, suit or proceeding.

          If the indemnification provided for in the second preceding paragraph
of this Commitment Letter is judicially determined to be unavailable (other than
in accordance with the terms hereof) to an Indemnified Person in respect of any
losses, claims, damages or liabilities referred to herein, then, in lieu of
indemnifying such Indemnified Person hereunder, URS agrees to contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities (and expenses relating thereto) (i) in such
proportion as is appropriate to reflect the relative benefits to URS on the one
hand, and the Purchasers, on the other hand, of the Transaction or (ii) if the
allocation provided by clause (i) is not available, in such proportion as is
appropriate to reflect not only the relative benefits referred to in such clause
(i) but also the relative fault of URS and the Purchasers, as well as any other
relevant equitable considerations; provided that in no event shall the
Purchasers' aggregate contribution to the amount paid or payable exceed the
aggregate amount of fees actually received by them under this Commitment Letter.

          URS  agrees to pay all reasonable legal and other out-of-pocket
expenses of the Purchasers in connection with this Commitment Letter, the
Financing Documentation and the other matters referred to herein, including
travel costs, document production and other expenses of this type, and the fees
of outside counsel and fees of other professional advisors, whether or not the
Acquisition is consummated or any Bridge Notes are actually issued.  In
addition, you hereby agree to pay when and as due the fees described in the Fee
Letter.

          This commitment will expire at the earliest of (a) 5:00 p.m. New York
City time on May 7, 1999 and (b) the execution of the Acquisition Agreement by
all parties thereto, unless accepted prior to such time and, if accepted prior
to such time, shall expire at the earliest of (i) 

 
                                       6

consummation of the Acquisition or another transaction or series of transactions
in which URS or any of its affiliates acquires, directly or indirectly, any
stock or assets of the Company, (ii) termination of the Acquisition Agreement,
(iii) consummation of the Permanent Financing and (iv) 5:00 p.m. New York City
time on September 30, 1999, if the closing of the Tender Offer shall not have
occurred by such time. No such termination shall affect your obligations under
each of the five immediately preceding paragraphs, including the obligation to
pay all fees set forth in the Fee Letter, which shall remain in full force and
effect regardless of any termination or the completion of the Transaction.

          This Commitment Letter shall be governed by the laws of the State of
New York.  Any right to trial by jury with respect to any claim, action, suit or
proceeding arising out of or contemplated by this letter is hereby waived and
the parties hereto hereby submit to the non-exclusive jurisdiction of the
federal and New York State courts located in the City of New York in connection
with any dispute related to this letter and/or any matters contemplated hereby.
This Commitment Letter is not assignable by you to any other person.  This
Commitment Letter and the Term Sheet (and the contents thereof) may not be
disclosed to any other person except your accountants and attorneys in
connection with the Acquisition and then only on a confidential basis and in
connection with the Transaction; provided that coincidental with your execution
of the Acquisition Agreement and delivery to the Board of Directors of the
Company you may disclose this Commitment Letter to the Company and its advisors,
RCBA and its advisors and Wells Fargo and its advisors and (ii) after your
acceptance of this Commitment Letter, you may reference the existence of, or
file, this Commitment Letter to the extent required in connection with any law
or regulation (including any securities law or regulation), order or decree.

          This Commitment Letter is not intended to confer upon any person,
other than the parties hereto, their successors hereunder and MS and its
affiliates, any benefit or any legal or equitable right, remedy or claim
hereunder.

                  SENIOR SUBORDINATED INCREASING RATE NOTES:

                       SUMMARY OF TERMS AND CONDITIONS/1/ 


Issuer:               URS.

Issue:                Unsecured Senior Subordinated Increasing Rate Notes (the
                      "Bridge Notes") issued pursuant to a Securities Purchase
                      Agreement (the "Securities Purchase Agreement") between
                      the Issuer and the Purchasers.

Use of Proceeds:      The proceeds of the Bridge Notes, along with borrowings
                      under the term loan and revolving loan portions of the
                      Senior Bank Financing and proceeds from the Equity
                      Contribution, will be used (i) to finance the purchase
                      price of the Acquisition (including any appraisal rights
                      in connection therewith), (ii) to refinance certain
                      existing debt of the Issuer and the Company, and (iii) to
                      pay costs and expenses in connection with the Transaction.

Principal Amount:     Up to $200.0 million.

Price:                100% of the principal amount.

Interest Rate:        Interest on the Bridge Notes shall be paid at the
                      Applicable Bridge Note Interest Rate (as defined below)
                      and payable quarterly in arrears. "Applicable Bridge Note
                      Interest Rate" means the higher of the following, as
                      determined as of the beginning of each three-month period:
                      (i) three-month U.S. Dollar LIBOR (as determined from
                      specified sources) plus 650 basis points and (ii) the

- --------------------
/1/   Capitalized terms used but not defined herein are used as defined in the
      Commitment Letter (the "Commitment Letter") to which this Summary of Terms
      and Conditions is attached.


                      highest yield on any of the 1-, 3-, 5- and 10-year direct
                      obligations issued by the United States plus 600 basis
                      points; provided that if the Bridge Notes are not retired
                      in whole by the end of the first six months following the
                      issuance date, the Applicable Bridge Note Interest Rate
                      otherwise in effect will increase by 100 basis points and
                      shall thereafter increase by an additional 50 basis points
                      at the end of each subsequent three-month period for so
                      long as the Bridge Notes are outstanding (the aggregate
                      number of basis points by which the Applicable Bridge Note
                      Interest Rate has so increased during the term of the
                      Bridge Notes being the "Incremental Spread"); and provided
                      further that (A) in no event shall the Applicable Bridge
                      Note Interest Rate exceed 17.0% and (B) the amount of cash
                      interest paid will be subject to a cap of 15.0%, with the
                      excess (if any) of the Applicable Bridge Note Interest
                      Rate over such interest rate cap to be paid in additional
                      Bridge Notes.

Maturity:             One year from the date of issuance.

Ranking:              The Bridge Notes will be unsecured and senior to all
                      subordinated indebtedness of the Issuer and will be pari
                      passu with all other unsubordinated indebtedness of the
                      Issuer except that they will be subordinated to the Senior
                      Bank Financing and any refinancing or renewal thereof.

Guarantees:           Same guarantees as are provided to the lenders under the
                      Senior Bank Financing (the "Senior Lenders") but the
                      guarantees will be unsecured and senior to all
                      subordinated indebtedness of the guarantor and will be
                      pari passu with all other unsubordinated indebtedness of
                      the guarantor, except that they will be subordinated to
                      the guarantor's guarantee of the Issuer's obligations
                      under the Senior Bank Financing or any refinancing or
                      renewal thereof. Upon a release by the Senior Lenders of
                      the guarantee by any subsidiary guarantor under the Senior
                      Bank Financing, any guarantee by such subsidiary hereunder
                      shall also be released.

Mandatory Redemption: The Issuer will redeem the Bridge Notes at 100% of their
                      principal amount plus accrued interest to the redemption
                      date with (i) the net proceeds from the Permanent
                      Financing, (ii) to the extent not required to prepay the
                      Senior Bank Financing, the net proceeds from the issuance
                      of any other debt or equity securities (with exceptions to
                      be determined) and (iii) to the extent not required to
                      prepay the

                                      A-2


                      Senior Bank Financing, the net proceeds from asset sales
                      (with exceptions to be determined).

Change-of-Control:    The Issuer will redeem the Bridge Notes upon any 
                      change-of-control (to be defined in a mutually acceptable
                      manner) of the Issuer at a redemption price of 101% of par
                      plus accrued interest.

Optional Redemption:  The Bridge Notes will be callable, in whole or in part,
                      upon not less than 10 days written notice, at the option
                      of the Issuer, at any time at 100% of par plus accrued
                      interest to the redemption date.

Mandatory Exchange:   If the Bridge Notes have not been previously redeemed in
                      full for cash on or prior to maturity, the principal of
                      the Bridge Notes outstanding at maturity shall, subject to
                      certain conditions precedent, be satisfied at maturity
                      through the issuance and delivery of the Rollover Notes
                      described below in the attached term sheet (Exhibit B).

Right to Resell
Bridge Notes:         The Purchasers shall have the absolute and unconditional
                      right, consistent with applicable securities laws, to
                      resell the Bridge Notes to one or more third parties,

                          probable liability on its debts as they become
                          absolute and matured, (iii) such person does not

                          debts or

                                      A-5


                          liabilities beyond its ability to pay as such debts

                          engaged, and is not about to engage, in business or a
                          transaction for which its property would constitute an
                          unreasonably small capital.

                          issuance of appropriate subsidiary guarantees, and
                          receipt by the Purchasers of reasonably satisfactory
                          opinions of counsel to the Issuer and to the
                          Purchasers as to the Transaction, together with
                          customary closing documentation.

                      6.  All material governmental and third party consents and
                          approvals necessary in connection with the Transaction
                          and the issuance of the Bridge Notes shall have been
                          obtained (without the imposition of any material
                          conditions that are not acceptable to the Purchasers)
                          and shall remain in effect; all applicable waiting
                          periods shall have expired without any adverse action
                          being taken by any competent authority; and no law or

                          Required Purchasers that restrains, prevents or
                          imposes materially adverse conditions upon the

                          its subsidiaries, taken as a whole, or the Company and
                          its subsidiaries, taken as a whole, since the end of
                          the most recent fiscal year (October 31, 1998) in the

                          fiscal quarter (December 25, 1998) for fiscal 1998 in

                          events or

                          circumstances) shall have come to the attention of
                          Purchasers that are inconsistent with the information
                          disclosed to the Purchasers by or on behalf of the
                          Issuer or the Company prior to the date of the
                          Commitment Letter and that, either individually or in
                          the aggregate, could reasonably be expected, in the
                          reasonable judgment of the Purchasers, to have a
                          material adverse effect on (a) the business, financial
                          condition, operations, performance, properties or

                          Guarantors to perform their obligations to the
                          Purchasers (collectively, a "Material Adverse

                      8.  There shall exist no action, suit, investigation,
                          litigation or proceeding (including those pertaining
                          to environmental matters) pending or threatened in any
                          court or before any arbitrator or governmental or
                          regulatory agency or authority that could reasonably
                          be expected to have a Material Adverse Effect (except
                          for such actions, suits, investigations, litigation
                          and proceedings disclosed to the Purchasers prior to
                          the date of the Commitment Letter).

                      9.  Absence of any disruption or change in financial,
                          banking or capital markets or in the regulatory
                          environment that in the good faith judgment of the
                          Purchasers could materially and adversely affect the
                          sale of the Bridge Notes or the refinancing thereof.

                          limitation, reasonable legal fees and expenses) and
