      judgment, order or decree applicable to RCG.

   (d) Insurance Company Regulations. To the knowledge of RCG, after due
      inquiry, the fact that its parent, Reliance Insurance Company, is an

      acquired "as-is". Except as set forth in this Agreement, RCG will not be
      responsible for any liabilities or obligations of the Company, known or
      unknown, absolute or contingent arising before or after the Closing Date.

   (h) Litigation. Except as set forth on Schedule 4(h), there are no lawsuits
      or claims pending against RCG as of the date of this Agreement and
      relating to the Company with respect to which RCG has knowledge and which

      transactions contemplated hereby.

   (i) Related Party Transactions. Except as set forth on Schedule 4(i) hereto,

      enforceability may be subject to bankruptcy, insolvency, reorganization,
      moratorium or other laws, decisions or equitable principles now or
      hereafter in effect relating to or affecting the enforcement of creditors'
      rights or debtors' obligations generally, and (ii) that the remedy of

      defenses and to the discretion of the court before which any proceeding
      therefor may be brought.

   (c) No Conflicts. The execution and delivery of this Agreement by Consulting
      does not, and the consummation of the transactions contemplated hereby and
      compliance with the terms hereof will not, conflict with, or result in any
      violation of, or default (with or without notice or lapse of time, or
      both) under, or give rise to a right of termination, cancellation or
      acceleration of any obligation or to loss of a material benefit under, or,
      except under the terms of the Credit Agreement and Security Documents
      (each as defined in the Consulting Note) and the Bridge Note, result in
      the creation of any lien, claim, encumbrance, security interest, option,
      charge or restriction of any kind upon any of the properties or assets of
      Consulting under any provision of (i) the certificate of incorporation or

      any material statute, law, ordinance, rule or regulation applicable to
      Consulting or its assets.

   (d) Actions and Proceedings. There are no (i) outstanding judgments, orders,
      writs, injunctions or decrees of any court, governmental agency or
      arbitration tribunal against Consulting or, to the knowledge of
      Consulting, the Company which would have a material adverse effect on the
      ability of Consulting to consummate the transactions contemplated hereby
      or (ii) actions, suits, claims or legal, administrative or arbitration
      proceedings or investigations pending or, to the knowledge of Consulting,
      threatened against Consulting or, to the knowledge of Consulting, the

   (e) Disclosure. As of the date hereof, Consulting has furnished RCG with the
      financial statements and other reports listed in Schedule 5(e) attached
      hereto. Such financial statements have been prepared in accordance with
      generally accepted accounting principles applied on a consistent basis and
      fairly present the financial position and results of operations of the
      persons to which they purport to relate as of the dates and for the
      periods indicated, with the exception of year-end adjustments and
      footnotes. Between the end of the most recent fiscal period shown in such
      financial statements and the date hereof, except as set forth m Schedule
      5(e) hereto, there has not been any material adverse change in the
      business, operations, properties or financial position of Consulting (or
      of the persons to which such financial statements purport to relate).
      Neither this Agreement nor any financial statements, reports or other
      documents or


                                      -5-


      certificates furnished to RCG by Consulting in connection with the
      transactions contemplated hereby contain any untrue statement of a
      material fact or omit to state any material fact necessary to make the
      statements herein or therein contained not misleading. Neither the loans
      made to the Company pursuant to the Subordinated Note, the Bridge Note or
      the senior bank facility or all such loans in the aggregate will render
      the Company unable to pay its debts as they become due; Consulting is not
      contemplating either the filing of a petition by it under any state or
      federal bankruptcy or insolvency laws or the liquidation of all or a major
      portion of its property; and Consulting has no knowledge of any person
      contemplating the filing of any such petition against it.
     
   (f) Securities Laws. Consulting is acquiring the Common Stock to be purchased
      pursuant to this Agreement for its own account and with no present
      intention of distribution or reselling the Common Stock being purchased by
      it in any transaction which would be in violation of the securities laws
      of the United States of America or any state thereof. The capital stock of
      Hagler Bailly, Inc., the parent of Consulting ("Hagler"), has been issued
      in compliance with all applicable federal and state securities laws.
     
   (g) Compliance with Lease Terms. The Company is in material compliance with
      each covenant, agreement and condition contained in the Lease (as defined
      in Section 6(f) below) other than its monetary obligations thereunder.
      With respect to monetary obligations under the Lease, the Company is in
      complete compliance therewith. Neither the Company nor Consulting knows of
      any event or condition that could give rise to a default under the Lease.

6. Covenants.

   (a) Consulting shall obtain all required governmental consents (including any
      necessary filings under the Hart-Scott-Rodino Antitrust Improvements Act),
      permissions, assignments of contracts, security clearances, and any other
      agreements required by it or the Company to acquire and own the Common
      Stock, except, in the case of the Company, such consents as may be
      required to be obtained by the Company or filings made by the Company
      solely by virtue of the Company's affiliation with RCG or Reliance
      Insurance Company (the "Consents").
     
   (b) RCG shall be responsible for any obligation or liability of the Company,
      absolute or contingent, arising with respect to the period prior to the
      Closing Date but after the Original Acquisition Date and

(A)known to RCG but not known to the Company or any Key Employee on or before
the Closing Date; or


                                       -6-


(B)not known to any of RCG, the Company or any Key Employee on or before the
Closing Date;

      and which, in the case of clause (B), arises principally from the failure
      by RCG or any person (other than an officer, director or employee of the
      Company) acting for, at the direction of, or for the benefit of RCG or its
      affiliates (other than the Company or its subsidiaries) to perform
      properly any obligation described on Schedule 6(b) hereof.

   (c) Consulting shall be responsible for any obligation or liability of the
      Company, absolute or contingent, arising before, on or after the Closing
      Date and

(A)known to the Company (even if also known to RCG) (on or prior to the Closing
Date, with respect to those liabilities arising with respect to the period on or
prior to the Closing Date) or;

(B)not known to either RCG or the Company (on or prior to the Closing Date, with
respect to those liabilities arising with respect to the period on or prior to
the Closing Date) and which, in the case of this clause (B), arises from any
cause other than the failure by RCG or any person (other than an officer,
director or employee of the Company) acting for, at the direction of, or for the
benefit of RCG or its affiliates (other than the Company or its subsidiaries) to
perform any obligation described on Schedule 6(b) hereof.

   (d) Consulting agrees that, immediately after the Closing Date, it will, and
      will cause the Company to delete all references to "RCG" or Reliance Group
      Holdings, Inc., from its name and from any letters, documents, or
      instruments relating to the Company or Consulting.

   (e) RCG or its affiliates will provide payroll services to the Company, at a
      cost, for the periods and on terms and conditions set forth on Exhibit D.

   (f) (i) Consulting agrees that it will endeavor to obtain for RCG a release
      (in form and substance satisfactory to RCG) (the "RCG Release") of all of
      RCG's obligations under all guarantees relating to the lease dated as of
      October 25, 1991 between the Company and Wilson Boulevard Venture
      (together with its successors and assigns, the "Landlord"), as amended by
      the First and Second Amendments thereto dated as of February__, 1993 and
      December 12, 1994, respectively (the "Lease). On the Closing Date,
      Consulting agrees to establish a reserve fund (the "Fund") at Chemical
      Bank, which shall have on deposit therein (A) at all times at least
      $180,000, prior to such date as the Revolving Commitment (as defined in
      the Credit Agreement) is raised to $4,500,000 and the cash collateral is
      released pursuant to Section 6.12(c) of the Credit Agreement (the "Initial
      Deposit End Date"), (B) at all times at least $350,000 from the Initial
      Deposit End Date through December 31, 1997, (C) at all


                                      -7-


      times at least $450,000 from January 1, 1998 through December 31, 1998
      (provided that the Initial Deposit End Date has occurred), and (D) at all
      times at least $550,000 after December 31, 1998 (provided that the Initial
      Deposit End Date has occurred); provided that the Fund may be discontinued
      and closed-out by Consulting on such date as the RCG Release is
      effectuated or during any period in which there is in full force and
      effect a surety bond from an insurance company, in an amount and
      containing such terms as are reasonably satisfactory to RCG (a "Surety
      Bond"). Any money in the Fund shall be immediately disbursed to RCG at
      such time as any monetary obligations under the Lease are due and unpaid
      (after giving effect to applicable grace periods in the Lease). In the
      event that the RCG Release is not effectuated by June 30, 1996, Consulting
      shall endeavor to obtain and keep in full force and effect, until such RCG
      Release is obtained, a Surety Bond; provided that the obligation to obtain
      and keep in full force and effect a Surety Bond shall be solely in the
      good faith business discretion of Consulting. RCG agrees to pay the first
      $50,000 in premium payments for the Surety Bond for each of any two full
      twelve-month periods ending prior to June 30, 1998 covered thereby (which
      premiums shall be paid by RCG to the insurance company issuing the Surety
      Bond). Any amount in excess of $50,000 for each of such two twelve-month
      periods and all amounts thereafter with respect to the Surety Bond, if
      obtained, shall be the responsibility of Consulting.

            (ii) Notwithstanding anything contained in this Section 6(f) to the
            contrary, in the event that the RCG Release is obtained prior to
            June 30, 1998 and a condition thereto is the payment of money to the
            Landlord, RCG agrees to pay to the Landlord an amount equal to the
            lesser of (i) the excess of $100,000 ($50,000 after June 30, 1996)
            over the amount previously paid or payable by RCG in respect of a
            Surety Bond and (ii) the amount of the required payment to the
            Landlord.

            (iii) Consulting shall deliver to RCG, no later than 10 days after
            the end of each fiscal quarter, a statement showing the amount on
            deposit in the Fund (or, a statement from its chief financial
            officer that no Fund is required pursuant to this paragraph (f)
            because a Surety Bond is in full force and effect) and a certificate
            from its chief financial officer to the effect that all of the
            monetary obligations of Consulting under the Lease for the three
            months included in such quarter were timely paid and that no other
            default exists under the Lease.

   (g) On or before June 29, 1995, Consulting shall provide to RCG a balance
      sheet as at the Closing Date and an income statement for the period
      beginning on May 1, 1995 and ending on the Closing Date, each of which
      shall be certified by the chief financial officer of Consulting and must
      be satisfactory in scope and form to RCG and be prepared on a basis
      consistent with past practices. Consulting agrees to pay to RCG an amount
      equal to the excess, if any, of the product of 35% times the earnings of


                                       -8-


      the Company reflected on such income statement (the "Actual Tax Payment")
      over the Estimated Tax Payment. RCG agrees to pay to Consulting the
      amount, if any, by which the Estimated Tax Payment exceeds the Actual Tax
      Payment. Any payments to be made by RCG or Consulting under this
      subparagraph (g) shall be made in immediately available funds no later
      than July 5, 1995.

   (h) RCG agrees that each of the Key Employees who is also an officer or
      director of RCG shall be entitled, in their capacities as such, to such
      indemnification as is provided to officers and directors of RCG pursuant
      to Article VIII of RCG's Bylaws, as in effect on the date hereof.

7. Indemnification.

      RCG shall indemnify Consulting, its affiliates and each of their
      respective officers, directors, employees and agents against and hold them
      harmless from any loss, liability, claim, damage or expense (including

      indemnified party to the extent arising from (i) any breach of any
      representation, warranty or covenant of RCG contained in this Agreement or

      or incurred by any such indemnified party to the extent arising from (i)
      any breach of any representation, warranty or covenant of Consulting
      contained in this Agreement or (ii) any claim made by any landlord or
      employee of the Company against RCG or any of its affiliates (other than
      the Company and its subsidiaries) in respect of any of the items listed on
      Exhibit C hereto or (iii) any matter for which Consulting is responsible
      as provided in Section 6(c) above.

      (c) Procedures Relating to Indemnification.

         (i) Notice. In order for a party to be entitled to any indemnification
             provided for under this Agreement in respect of, arising out of or
             involving a claim or demand made by any person, firm, governmental
             authority or corporation against the indemnified party (a "Third
             Party Claim"), such indemnified party


                                      -9-


            must notify the indemnifying party in writing, and in reasonable
            detail, of the Third Party Claim as promptly as reasonably possible
            after receipt by such indemnified party of written notice of the
            Third Party Claim. Thereafter, if the indemnifying has assumed the
            defense of such Third Party Claim, the indemnified party shall
            deliver to the indemnifying party, within three business days after
            the indemnified party's receipt thereof, copies of all notices and
            documents (including court papers) received by the indemnified party
            relating to the Third Party Claim. Notwithstanding anything
            contained in this subparagraph (c) to the contrary, the failure to
            deliver any notices or documents required to be delivered pursuant
            to this subparagraph (c) shall not affect the indemnification
            provided hereunder except to the extent the indemnifying party shall
            have been actually prejudiced as a result of such failure.

            (ii)  Defense. If a Third Party Claim is made against an indemnified
                  party, the indemnifying party will be entitled to participate
                  in the defense thereof and, if it so chooses, to assume the
                  defense thereof with counsel selected by the indemnifying
                  party and reasonably satisfactory to the indemnified party.
                  Should the indemnifying party so elect to assume the defense
                  of a Third Party Claim, the indemnifying party will not be
                  liable to the indemnified party for legal expenses
                  subsequently incurred by the indemnified party in connection
                  with the defense thereof. If the indemnifying party assumes
                  such defense, the indemnified party shall have the right to
                  participate in the defense thereof and to employ counsel, at
                  its own expense, separate from the counsel employed by the
                  indemnifying party, it being understood that the indemnifying
                  party shall control such defense. The indemnifying party shall
                  be liable for the fees and expenses of counsel employed by the
                  indemnified party for any period during which the indemnifying
                  party has not assumed the defense thereof; provided, however,
                  that if the indemnified party's counsel determines that the
                  indemnified party has or may have defenses to the Third Party
                  Claim apart from or conflicting with the defenses of the
                  indemnifying party, then the indemnified party shall be
                  entitled to retain its own separate counsel and the
                  indemnifying party shall be liable for legal expenses incurred
                  by the indemnified party in the defense of such Third Party
                  Claim. If the indemnifying party chooses to defend any Third
                  Party Claim, all the parties thereto shall cooperate in the
                  defense or prosecution thereof. Such cooperation shall include
                  the retention and (upon the indemnifying party's request)
                  access to the indemnifying party of records and information
                  which are reasonably relevant to such Third Party Claim, and
                  making employees available on a mutually convenient basis to
                  provide additional information and explanation of any material
                  provided hereunder. Whether or not the indemnifying party
                  shall have assumed the defense of a Third Party Claim,


                                      -10-


                  the indemnified party shall not admit any liability with
                  respect to, or settle, compromise or discharge such Third
                  Party Claim without the indemnifying party's prior written
                  consent (which consent shall not be unreasonably
                  withheld). If the indemnifying party shall have assumed
                  the defense of a Third Party Claim, the indemnifying party
                  shall not settle such Third Party Claim without the
                  indemnified party's prior written consent (which consent
                  shall not be unreasonably withheld).

                  Notwithstanding the foregoing, if there is a reasonable
                  probability that the indemnifying party will not be able to
                  satisfy its indemnification obligations under this Section 7,
                  the indemnified party will have the right to defend and, after
                  reasonable consultation with the indemnifying party, to
                  compromise or settle the Third Party Claim.

      (d) In no event shall Consulting have any right to set-off against the
          Bridge Note or the Consulting Note any amount due from RCG to
          Consulting under this Section 7, but RCG shall be entitled to credit,
          dollar for dollar, the Consulting Note for any amount due from RCG
          under this Section 7.

                        filed with respect to the Company for a Post-Affiliation
                        Year that results in an increase in Taxes payable by
                        Consulting or the Company; and

                  (y)   such Adjustment results in a corresponding Adjustment to
                        items reported on a return filed with respect to RCG or
                        any affiliate of RCG (including the Company) for an

                  (z)   the Taxes payable by or on behalf of RCG (or such

                        are reduced by such Adjustment (the "RCG Decrease"),

                        Decrease. Payment under this paragraph shall be made no

                        results in an increase in the Taxes payable by RCG or an
                        affiliate of RCG; and

                  (y)   such Adjustment results in a corresponding Adjustment to
                        items reported on a tax return filed with respect to
                        Consulting or any affiliate of Consulting (including the

                  (z)   the Taxes payable by or on behalf of Consulting (or such
                        affiliate) with respect to such Post-Affiliation period
                        are reduced by such Adjustment (the "Consulting
                        Decrease"), then Consulting shall pay to RCG an amount
                        equal to such increase in Taxes of RCG or such
                        affiliate. The amount payable by Consulting under this
                        paragraph shall be limited to the Consulting Decrease,
                        plus interest calculated as under pursuant to Code
                        Section 6621, or comparable interest from state or local

                  Consolidated Return for an Affiliation Year:

                  (x)   the Company's taxable income is determined (by
                        Consulting or RCG with the agreement of the other that
                        the change is appropriate, or by the IRS) to be greater
                        than its taxable income as originally reported on such
                        Consolidated Return (other than as a result of an
                        Adjustment described in subparagraph (c)(i) or (c)(ii)
                        above), the Company shall pay to RCG an amount equal to

                  (y)   the Company's taxable income is determined (by
                        Consulting or RCG with the agreement of the other that
                        the change is appropriate, or by the IRS) to be less
                        than its taxable income as originally reported on such
                        Consolidated Return (other than as a result of an
                        Adjustment described in subparagraph (c)(i) or (c)(ii)
                        above, RCG shall pay to Consulting an amount equal to
                        the product of the reduction in taxable income and the
                        maximum federal Tax rate for the applicable year (plus
                        interest);

                  (z)   Payment pursuant to this subparagraph (iii) shall be
                        made no later than five (5) business days after RCG
                        receives or otherwise actually realizes a refund of or
                        is assessed the additional tax.

            (iv)  Notice of Adjustments by RCG. RCG shall promptly notify
                  Consulting of any IRS notice or revenue agent's report or
                  equivalent state or local tax authority notice received by RCG
                  which could result in an Adjustment giving rise to a liability
                  of Consulting or the Company under this Agreement. However,
                  the failure to give such notice shall not relieve Consulting
                  or the Company from any liability that it may have hereunder,
                  except to the extent that such failure results in increased
                  liability to Consulting or the Company arising out of its
                  obligations to pay RCG as provided in this Section 8. RCG
                  shall keep Consulting informed of developments regarding such
                  notice or report and shall consult with the Company or
                  Consulting concerning the appropriate actions or positions to
                  be taken in such proceedings to the extent such developments:

                  (x)   relate to any liability of Consulting or the Company to
                        RCG under this Agreement, or

                  (y)   could affect the liability of Consulting or the Company
                        for Taxes in a Post-Affiliation Year.

            (v)   Notice of Adjustments by Consulting and the Company.
                  Consulting shall promptly notify RCG of any IRS notice or
                  revenue agent's report or equivalent state or local tax
                  authority notice received by Consulting or the Company which
                  could result in an Adjustment giving rise to a liability of
                  RCG under this Agreement. However, the failure to give such
                  notice shall not relieve RCG from any liability that it may
                  have hereunder, except to the extent that such failure results
                  in increased liability to RCG arising out of its obligations
                  to pay Consulting. Consulting shall keep RCG informed of
                  developments regarding such report or notice to the extent
                  such developments relate to any liability of RCG to Consulting
                  or the Company under this Agreement.


                                      -16-


      (d)   Indemnification. RCG agrees to pay and shall indemnify and hold
            harmless the Company and Consulting from and against all Taxes, and
            RCG shall be entitled to receive and retain all refunds of Taxes, in
            each case, only to the extent attributable to the operations or
            assets of any member of the Affiliated Group other than the Company
            and its subsidiaries.

      (e)   Cooperation; Furnishing of Information. The parties agree to provide
            each other with such cooperation and information as may be
            reasonably requested in connection with:

            (i)   the preparation or filing of any Tax return, report, amended
                  return or claim for refund with respect to Taxes;

            (ii)  the conduct of any audit; or

            (iii) making any other computation or determination required
                  hereunder.

      (f)   Record Retention. RCG and the Company shall retain all relevant tax
            returns, schedules and workpapers, and all related material records
            or other documents until the expiration of the statute of
            limitations (including extensions) of the taxable years to which
            such returns and other documents relate, but in any event for a
            period of not less than seven (7) years, provided, however, that RCG
            is not required to retain any documents which have been furnished to
            the Company or Consulting.

      (g)   Code Section 338(h)(10) Election.

            (i)   Subject to subparagraph (g)(iii) below, Consulting agrees to,
                  and RCG agrees to have its parent entity, join in a Code
                  Section 338(h)(10) Election with respect to the acquisition by
                  Consulting of the Common Stock. RCG agrees to execute Form
                  8023-A (or any replacement form), to comply with all the
                  requirements of Code Section 338(h)(10) and Regulations
                  promulgated thereunder, and to take any other action
                  reasonably requested by Consulting in order to make and
                  effectuate this election. Other than as set forth in this
                  paragraph (g), all Taxes arising as a result of the Code
                  Section 338(h)(10) Election are the responsibility of the
                  Company or Consulting.

            (ii)  Notwithstanding the provisions of subparagraph (g)(i) above,
                  in the event of a failure to make a Code Section 338(h)(10)
                  Election, other than a failure resulting from a breach by RCG
                  or its parent entity of the provisions of this paragraph (g),
                  RCG shall have no liability for any such Taxes resulting from
                  any other election made by Consulting pursuant to Code Section
                  338. RCG and Consulting agree to use their best efforts to
                  agree on an allocation of the purchase price among the assets
                  of the Company as of the Closing that is


                                      -17-


                  acceptable to both parties. In the event that such agreement
                  has not been reached by June 29, 1995, Consulting shall obtain
                  and deliver to RCG an appraisal of such assets performed by an
                  appraiser selected and paid by Consulting. Such appraisal
                  shall be obtained by Consulting and delivered to RCG by August
                  15, 1995 and shall be used by Consulting and RCG in allocating
                  and reporting the fair market values of the assets of the
                  Company for purposes of Code Section 338. Prior to June 29,
                  1995, Consulting shall prepare and deliver to RCG a schedule
                  showing state apportionments of payroll, property and sales
                  for the period January 1, 1995 through the Closing Date in a
                  form consistent with those schedules delivered to RCG by the
                  Company in prior years.

            (iii) Notwithstanding anything contained in this subparagraph
                  (g)(iii) to the contrary, RCG's parent entity shall have no
                  obligation to join in, and Consulting shall not file a Code
                  Section 338(h)(10) Election unless (A) Consulting has paid to
                  each appropriate state taxing authority, at such time as the
                  extension for such state return is filed pursuant to
                  subparagraph (b)(iv) of this Section 8, an amount equal to the
                  state Taxes to be paid as a result of the Code Section
                  338(h)(10) Election, based on the allocations agreed to by RCG
                  and Consulting pursuant to subparagraph (g)(ii) above, (B)
                  prior to such filing, Consulting has executed and delivered to
                  RCG (i) a promissory note (pari passu with the Credit
                  Agreement) in a principal amount equal to the Incremental
                  Federal Income Taxes and on such terms as are contained in,
                  and in the form attached hereto as Exhibit E (the "Tax Note"),
                  (ii) a guaranty of the Tax Note by Hagler (pari passu with the
                  guaranty by Hagler granted to the Bank under the Credit
                  Agreement) in the form attached hereto as Exhibit E-1 and
                  (iii) evidence that the Bank (as defined in the Credit
                  Agreement) has consented to the Tax Note and the Hagler
                  guaranty thereof, and (C) the Bridge Note has been repaid in
                  full.

9. Termination.

The agreement of RCG to sell and of Consulting to purchase the Common Stock
shall terminate on the close of business on May 26, 1995 (unless extended by
written agreement among the parties) if the Closing shall not have occurred

Company for work on this transaction) and/or Consulting (including the formation

survive the Closing hereunder.

indemnifying party in connection with the transactions contemplated by this
Agreement.

termination of the Credit Agreement, provided that in the event that any
provision of Section 7 of the Credit Agreement is waived (or amended in a manner
which has the effect of being a waiver, i.e., such amendment is not modifying
future compliance with the Credit Agreement) and the Company has certified to
Holder that no consideration has been offered or given by the Company or Hagler
to the person consenting to such waiver or amendment in order to obtain such
waiver or amendment and has requested Holder to consent in writing to such

to the Company for cancellation, and in the case of loss, an agreement of
indemnity by Holder, the Company at its expense will execute and deliver, in

            fail to make such amortization payments when due (or within 90 days
            of the date provided for in the Credit Agreement, provided that
            acceptance of such late payment by State Street Bank and Trust
            Company shall not be deemed a waiver under clause (i) above); or

                  (e) if the Company shall fail to perform or comply with (i)

Dear Linda and Lowell:

In the spirit of the covenants that are likely to be included in the final
Credit Agreement and Subordinated Note we have been negotiating with you, the
purpose of this letter is to inform you of some recent developments concerning
the U.S. Agency for International Development (USAID) which could adversely
affect Hagler Bailly's financial performance in the coming months. As you know,
USAID is the single largest client of the firm. Over the first four months of
this year, it accounted for approximately 62% of our gross revenues, 44% of our
net revenues and 40% of our gross profits.

First, on May 9, we received a copy of a memorandum for USAID (dated April 24,
1995) informing us to start clearing all major expenses with our cognizant
contracting officer. A copy of this memorandum is enclosed. Second, last night,
the House Budget Committee voted to abolish USAID, fold USAID's functions into
the State Department and substantially cut the U.S. foreign assistance budget.
Specifically, the House proposed a 25% cut in assistance to Russia which has
been a major source of revenue for us.


Ms. Linda A. Moulton
Mr. Lowell C. Freilberg

Needless to say we are following these developments very closely to ensure they
do not materially affect the overall financial performance of the company.
Despite these uncertainties, management is still committed to the repurchase of
the firm from RCG International. If you have any questions or need additional
information please call me.

Sincerely yours,

/s/ Henri-Claude Bailly

MEMORANDUM FOR ALL USAID CONTRACTORS, GRANTEES AND RECIPIENTS

FROM:          Michael D. Sherwin, Procurement Executive

SUBJECT:       Possible USAID Budget Reductions


As you may be aware, there are currently very serious discussions underway in
the U.S. Congress regarding possible rescissions of the approved Fiscal Year
1995 U.S. Agency for International Development (USAID) budget. Concurrently, the
Congress is also discussing very significant reductions in the proposed Fiscal
Year 1996 budget request for USAID.

As a result of the aforementioned deliberations, we must take precautions
regarding upcoming incurrence of expenses under all USAID procurement and
assistance instruments currently in effect. Cuts of the magnitude being
discussed could cause significant changes or, in some cases, outright
termination of procurement and "assistance" instruments.

Therefore, effective this date, you are hereby notified to contact your
cognizant Contracting, Grant or Agreement Officer of record before any major
expenses are incurred, until further advised. Examples would include major
subcontractors, major equipment procurements, mobilization of long-term overseas
personnel, etc.

Further information may be obtained from our cognizant official in the USAID
Office of Procurement.


                                  SCHEDULE 6(b)
                                 RCG Obligations
