                              EMPLOYMENT AGREEMENT

To Jonathan J. Ledecky:

         This Agreement establishes the terms of your employment with Aztec
Technology Partners, Inc., a Delaware corporation (the "Company"), as of June
10, 1998. This Agreement is contingent on and subject to the closing of the
distribution (the "Distribution") to the U.S. Office Products Company ("USOP")
stockholders of the Company's stock. If the Distribution does not close by
September 30, 1998, this Agreement will have no force or effect.

Duties             You agree to serve as a senior consultant to the Company
              providing strategic business advice and high level acquisition
              negotiations. In that capacity, you will report to the Company's
              senior management and its Board of Directors (the "Board"). The
              Board can require such reports of your activities on the Company's
              behalf as it reasonably deems appropriate. It can require your
              services to the extent consistent with your other contractual
              employment obligations to Consolidation Capital Corporation
              ("CCC"), USOP, and the other subsidiaries ("Other Spincos") of
              USOP whose common stock will be distributed to the USOP
              stockholders concurrent with the Company's stock, with the
              specific timing of your services to be mutually agreed. You agree
              to comply with the Company's generally applicable personnel
              policies to the extent applicable to a person working on your
              schedule and consistent with your obligations in this Agreement.

Term               The term of this Agreement runs from the day following the
              effective date of the Distribution (the "Closing Date") through
              June 30, 2000, unless earlier terminated as provided in this
              Agreement.

Salary             You will receive an annual salary of $48,000 from the Closing
              Date, payable in accordance with the Company's payroll policies.

Benefits           You are eligible for participation in the Company's generally
              applicable benefit plans and programs (including its 401(k) Plan)
              to the extent you satisfy their terms for participation.

Expenses           The Company will make available to you, on an as needed and
              as mutually agreed basis, office space, secretarial assistance,
              and supplies for the direct performance of your services to the
              Company. It will pay or reimburse you for reasonable business
              expenses relating to the direct performance of such services, to
              limits to be mutually agreed in advance, upon proper and timely
              substantiation.

Options            You are receiving options for the Common Stock of the Company
              in consideration for services as an employee of the Company.

Option             Your options will cover 7.5% of the Company's outstanding
              common stock determined as of the Distribution Date (excluding the
              stock under the Company's initial public offering), with no
              anti-dilution provisions in the event of issuance of additional
              shares of

              common stock (other than with respect to stock splits or reverse
              stock splits).

Term               Your option will expire ten years from the Closing Date.

Price              Your option will have a per share exercise price equal to the
              offering price in the Company's initial public offering, or if no
              initial public offering commences on the Closing Date, at the fair
              market value of the Company's common stock, as determined under
              the Company's option plan, for the date of grant.

Schedule           Your option will be fully vested when granted, but may not be
              exercised until the first anniversary of the Closing Date.

              Your option will become exercisable before that first anniversary
              if and to the extent that the Company accelerates the
              exercisability of the options for substantially all management
              optionholders.

              All unexercised portions of your options will expire if, as
              finally determined by a court, you violate the No Competition
              provision.

Disgorging         If a court finds that you violated the No Competition
 Option       provision, you agree that your unexercised options are
  Gain        retroactively forfeited as of the date of the violation and
              that, if you have exercised the options since the violation began,
              you will promptly pay the Company any Option Gain, net of any
              taxes actually paid on the options. For purposes of this
              Agreement, the "Option Gain" per share you received on exercise of
              options on or after the violation is

              Stock          for stock you have sold, the greater of (i) the
              Sold           spread between closing price on the date of
                             exercise and the exercise price paid ("Exercise
                             Spread") and (ii) the spread between the price at
                             which you sold the stock and the exercise price
                             paid, and

              Stock          for stock you have retained, the greater of (i)
              Retained       Exercise Spread and (ii) the spread between the
                             closing price on the date of the court's final
                             determination and the exercise price paid.

              All unexpired options will vest and be exercisable at your death.

Termination        The Company can terminate your employment under this
              Agreement only for "cause." "Cause" means your (i) conviction of
              or guilty or nolo contendere plea to a felony demonstrably and
              materially injurious to the Company's business, and resulting in a
              sentence of imprisonment, or (ii), as finally determined by a
              court, violation of the No Competition provision as it applies to
              the Company, provided that the Company will give you 10 days to
              resolve the violation before attempting to invoke this termination
              provision. For a termination under (ii), you agree to repay any
              salary you received from the Company between the date of the
              violation and the date of the court's determination.

Severance          If your employment ends because you resign or are properly
              terminated for cause, you will not receive severance or
              termination pay and your salary will end. Except to the extent the
              law or the terms of an applicable plan requires otherwise, neither
              you nor your beneficiary or estate will have any rights or claims
              under this Agreement or otherwise to receive severance or any
              other compensation or to participate in any other plan,
              arrangement, or benefit, after your termination of employment,
              other than with respect to your options.

No                 Consistent with certain of your prior obligations to USOP,
Competition   you will not, until after the end of the Restricted Period, for
              any reason whatsoever, directly or indirectly, for yourself or on
              behalf

              partnership, corporation, or business of whatever nature:

Competition        (i) engage, as an officer, director, shareholder, owner,
              partner, joint venturer, or in a managerial capacity, whether as
              an employee, independent contractor, consultant, or advisor, or as
              a sales representative, in any business (other than an Excluded
              Business, as defined below) selling any products or services in
              direct competition with the Company within 100 miles of where the
              Company or where any of the Company's subsidiaries or affiliates
              regularly maintains any of its or their offices with employees
              (the "Territory"), where "products or services" are determined for
              this clause with respect to products or services offered on or
              before January 13, 1998 by the Company and/or any of its
              subsidiaries or the predecessor companies combined to form the
              Company in connection with Distribution and where the geographic
              limitation is determined with reference to the Company and its
              subsidiaries and not to USOP or the other Spincos (e.g.,
              competition with respect to the Company is determined by reference
              to the location where the Company or its subsidiary has an office
              with employees and not to the locations of offices of other
              Spincos);

Employees          (ii) call upon any person who is, at that time, within the
              Territory, an employee of the Company (including the respective
              subsidiaries and/or affiliates thereof) in a managerial capacity
              for the purpose or with the intent of enticing such employee away
              from or out of the Company's employ (including the respective
              subsidiaries and/or affiliates thereof) other than a member of
              your immediate family; or

Customers          (iii) call upon any person or entity that is, at that time,
              or that has been, within one year prior to that time, a customer
              of the Company (including the respective subsidiaries and/or
              affiliates thereof) within the Territory for the purpose of
              soliciting or selling products or services in direct competition
              with the Company (including the respective subsidiaries and/or
              affiliates thereof) within the Territory other than on behalf of
              an Excluded Business.

              For purposes of this Agreement, the "Restricted Period" ends, on
              the later of the second anniversary of the Closing Date and the
              date one year after you leave employment with the Company and its
              subsidiaries and affiliates.

              For purposes of this Agreement, the "Excluded Businesses" are the
              following:

                   (i) any electrical contracting business that, at the time of
                   its creation or acquisition and at all later times, derives
                   more than 50% of its revenues from electrical contracting and
                   maintenance services, without regard to whether it would
                   otherwise violate the No Competition clause because it is
                   engaged in a business directly competitive with the Company
                   or any of its subsidiaries (together, "Aztec"), provided that
                   this exclusion does not permit the business to engage in any
                   of the lines of business described under "Consulting and
                   Engineering Services," "Systems and Network Design and
                   Implementation Services," and "Software Development and
                   Implementation Services" in the Aztec Form S-1 filed on June
                   3, 1998 (the "Aztec Specified Businesses") other than as
                   provided under (ii) or (vi) in the Excluded Businesses;

                   (ii) any business whose revenue from activities that compete
                   with Aztec and its subsidiaries, at the time of the
                   business's creation or acquisition and at all later times, is
                   less than $15 million per year, provided that this exclusion
                   does not permit the business to engage in the Aztec Specified
                   Businesses other than (i) as provided under (vi) in the
                   Excluded Businesses or (ii) through the pending

                   (iv) any business engaged, and only to the extent that it is
                   so engaged, in the business of selling, supplying, or
                   distributing janitorial or sanitary products or services;

                   (other than computers);

                   (vi) any business engaged, and only to the extent it is so

                   registration statement filed on the date of this Agreement,
                   so long as you are solely an investor in USM and not an
                   officer, director, or employee of, or consultant to, USM;
                   provided, however, that your service as a director will not
                   violate the foregoing requirement as long as you cease to be
                   a director no later than the 90th day after the effective
                   date of the registration of USM's initial public offering;

                   provided, that in each case you are engaged in suchbusiness
                   only in a policy making role and not in the entity's business
                   in a manner that would involve you in direct personal
                   competition with the Company (and its subsidiaries), provided
                   further that this proviso does not prevent your activities in
                   furtherance of acquisitions of Excluded Businesses, and
                   provided further that you will comply with your fiduciary
                   duties as a director of the Company in connection with the
                   Excluded Businesses.

              To the extent permitted by your obligations to the relevant
              Excluded Business, as an employee and/or director of the Company
              (or its subsidiaries), you will inform the relevant entity of any
              opportunities for it associated with any of the Excluded
              Businesses.

              In addition to (and not in lieu of) the restriction contained in
              the Employees clause above, you agree that, during the period that
              the restrictions contained in this No Competition provision remain
              in effect, and so long as you are employed by, or otherwise
              affiliated with, CCC, you will not, directly or indirectly, offer
              employment with CCC to, or otherwise allow CCC to employ, any
              person who

                   is employed by the Company or a subsidiary of the Company at
                   the time; or

                   was so employed by the Company or a subsidiary of the Company
                   within one year prior to such time.

              Notwithstanding the above, the foregoing covenant shall not be
              deemed to prohibit you from acquiring capital stock in CCC or any
              Excluded Business or serving as an officer, director or employee
              or consultant to CCC, or acquiring as an investment not more than
              one percent (1%) of the capital stock of a competing business,
              whose stock is traded on a national securities exchange or
              over-the-counter, provided that such actions do not otherwise
              breach your obligations hereunder; and provided further that
              actions of CCC after you have ceased to be a director, officer,
              and employee of CCC will not constitute a breach of this covenant,
              despite your continued stock ownership, so long as you are not
              then directly assisting any competitive actions.

              Because of the difficulty of measuring economic losses to the
              Company as a result of a breach of the foregoing covenant, and
              because of the immediate and irreparable damage that could be
              caused to the Company for which it would have no other adequate
              remedy, you agree that the Company may enforce the No Competition
              provisions by injunctions and restraining orders.

              You and the Company agree that you will not be in violation of the
              No Competition provisions by virtue of your investment in or other
              relationship to USOP, any of the Spincos, or their respective
              subsidiaries, even if one of those entities engages in direct
              competition with another. You and the Company agree that CCC's
              acquisition or retention of Wilson Electric Company, Inc.
              ("Wilson") and Wilson's engaging in any lines of business in place
              as of the Closing Date do not violate the No Competition
              provision.

              You and the Company agree that the No Competition provisions
              impose a reasonable restraint on you in light of the Company's
              activities and business (including the Company's subsidiaries
              and/or affiliates) on the date of the execution of this Agreement.

              The Company agrees to consider reasonably and within two weeks of
              receipt any requests you make for a waiver from the No Competition
              provisions for a particular acquisition.

              You and the Company further agree that, if you enter into a
              business or pursue other activities not in competition with the
              Company (including the Company's subsidiaries), or similar
              activities or business in locations the operation of which, under
              such circumstances, does not violate the Competition clause of
              this No Competition provision, and in any event such new business,
              activities, or location is not in violation of this No Competition
              provision or of your obligations under this No Competition
              provision, if any, you will not be chargeable with a violation of
              this provision if the Company (including the Company's
              subsidiaries) shall thereafter enter the same, similar, or a
              competitive (i) business, (ii) course of activities, or (iii)
              location, as applicable.

              The covenants in this No Competition provision are severable and
              separate, and the unenforceability of any specific covenant does
              not affect the provisions of any other covenant. Moreover, if any
              court of competent jurisdiction shall determine that the scope,
              time, or territorial restrictions set forth are unreasonable, then
              it is the intention of the parties that such restrictions be
              enforced to the fullest extent which the court deems reasonable,
              and the Agreement shall thereby be reformed.

              All of the covenants in this No Competition provision shall be
              construed as an agreement independent of any other provision in
              this Agreement, and the existence of any claim or cause of action
              by you against the Company, whether predicated on this Agreement
              or otherwise, shall not constitute a defense to the enforcement by
              the Company of such covenants. It is specifically agreed that the
              Restricted Period, during which your agreements and covenants made
              in this provision shall be effective, is computed by excluding
              from such computation any time during which you are in violation
              of any provision of the No Competition provision.

              Notwithstanding any of the foregoing, if any applicable law
              reduces the time period during which you are prohibited from

                               THIRD AMENDMENT TO
                  REVOLVING CREDIT AGREEMENT AND LIMITED WAIVER

         Third Amendment and Limited Waiver dated as of March 30, 1999 to
Revolving Credit Agreement (the "Third Amendment"), by and among AZTEC
TECHNOLOGY PARTNERS, INC., a Delaware corporation (the "Borrower"),
PROFESSIONAL COMPUTER SOLUTIONS, INC. ("PCSI"), as Co-Borrower with respect
to $15,000,000 in outstanding principal amount of Acquisition Loans, FLEET
NATIONAL BANK (F/K/A BANKBOSTON, N.A.) and the other lending institutions
listed on SCHEDULE 1 to the Credit Agreement (as hereinafter defined) (the
"Banks"), amending certain provisions of the Revolving Credit Agreement dated
as of July 27, 1998 (as amended and in effect from time to time, the "Credit
Agreement") by and among the Borrower, the Banks and BankBoston, N.A. (now
known as Fleet National Bank) as agent for the Banks (the "Agent"). Terms not
otherwise defined herein which are defined in the Credit Agreement shall have
the same respective meanings herein as therein.

         WHEREAS, the Borrower has requested that the Banks amend certain
provisions contained in the Credit Agreement and waive certain covenants
contained therein; and

         WHEREAS, the Banks have agreed with the Borrower, subject to the
terms and conditions contained herein, to modify certain terms and conditions
of the Credit Agreement and grant such waivers as specifically set forth in
this Third Amendment;

         WHEREAS, to reflect the allocation of debt among the Borrower and
its Subsidiaries, one of such Subsidiaries, which is currently a Guarantor
under the Guaranty, has agreed to assume joint and several liability with
respect to $15,000,000 in outstanding principal amount of the Acquisition
Loans;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements contained herein and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties
hereto hereby agree as follows:

         Section 1. WAIVER. The Borrower has informed the Agent and the Banks
that the Leverage Ratio for the period of October 1, 1999 through December
31, 1999 (the "Fourth Quarter") exceeded 3.50:1.00 during such Fourth Quarter
and, as such, the Borrower has failed to comply with ss. 11.1 of the Credit
Agreement during the Fourth Quarter. In addition, the Borrower has informed
the Agent and the Banks that the ratio of EBITDA for the Reference Period
ended on December 31, 1999 to Consolidated Total Interest Expense for such
Reference Period was less than 2.75 to 1.00 and, as such, the Borrower has
failed to comply with ss. 11.3 of the Credit Agreement at the end of the
Fourth Quarter. The Borrower has requested that the Banks waive, to the
limited extent necessary to permit such noncompliance for the Fourth Quarter,
the provisions of ss.ss. 11.1 and 11.3 of the Credit Agreement. Subject to
the satisfaction of the conditions precedent set forth in Section 12 hereof,
from and after the Effective Date (as defined in ss. 12 hereof) the Banks
hereby waive the provisions of ss.ss. 11.1 and 11.3 of the Credit Agreement
solely to the extent necessary to permit the above-referenced noncompliance,
and only with respect to the determination of compliance for the Fourth
Quarter.

<PAGE>

         SS. 2. CONSENT AND WAIVER. The Agent and the Bank hereby consent to
the following, notwithstanding that the same would otherwise violate various
terms and provisions of the Credit Agreement, and hereby waive any Default
and Events of Default (and only such Defaults and Events of Default) that
would otherwise be caused by such violations:

         (a)      an  assignment  for the  benefit  of  creditors  with
respect  to the  stock or  assets of Entra Computer Corp. and the winding up
and termination of business of Entra Computer Corp.;

         (b)     the sale of the stock or assets of Compel LLC, Fortran Corp.
and Mahon Communications Corporation to Morganthaler Partners pursuant to an
existing letter of intent for a price of at least the "Purchase Price" set
forth on SCHEDULE A and resulting in Net Cash Sale Proceeds after payment of
all fees and expenses of the Agent and the Banks then outstanding, including
without limitation any unpaid Amendment Fee and any earned and unpaid
Overadvance Fees, of not less than the "Release Amount" set forth on SCHEDULE
A, provided that on or before June 30, 2000, the Borrower uses all of the Net
Cash Sale Proceeds, first to pay all fees and expenses of the Agent and the
Banks then outstanding, including without limitation, unpaid Amendment Fee
and any earned and unpaid Overadvance Fees, and second, to repay Acquisition
Loans (or, to the extent Acquisition Loans have been paid in full, to repay
Revolving Credit Loans and permanently reduce the Total Commitment) and
provided further that none of the documents with respect to such sale shall
contain any provision that would adversely affect in a material manner the
interests of the Banks under the Credit Agreement or the Security Documents
and, notwithstanding the foregoing, to the extent the Banks are required to
disgorge any Net Cash Sale Proceeds paid to them as a result of any
rescission right that a purchaser may have under applicable law with respect
to such sale, then the Obligations that had been deemed satisfied by the
application of such Net Cash Sale Proceeds shall be deemed reinstated and any
security interest in any Collateral that had been released in connection
therewith shall be deemed restored as if such payment had never occurred; and

         (c)      the sale of the stock or assets of any Subsidiary of the
Borrower (including any Subsidiary currently proposed to be sold to
Morganthaler as described in clause (b) above that is not sold pursuant to
the terms set forth in clause (b) above), to one or more unrelated third
parties in one or more arm's length transactions, for a price resulting in
Net Cash Sale Proceeds after payment of all fees and expenses of the Agent
and the Banks then outstanding, including without limitation any unpaid
Amendment Fee and any earned and unpaid Overadvance Fees, at least equal to
the Minimum Net Cash Sale Proceeds for such Subsidiary, provided that the
Borrower first pays all fees and expenses of the Agent and the Banks then
outstanding, including without limitation any unpaid Amendment Fee and any
earned and unpaid Overadvance Fees and then from the remaining Net Cash Sale
Proceeds of each such sale repays Acquisition Loans (or, to the extent
Acquisition Loans have been paid in full, repays Revolving Credit Loans and
permanently reduce the Total Commitment) in an amount equal to the sum of the
Minimum Net Cash Sale Proceeds for such Subsidiary and 80% of the Net Cash
Sale Proceeds of such sale in excess of the Minimum Net Cash Sale Proceeds
for such Subsidiary, on the date of receipt of such proceeds, and provided
further that none of the documents with respect to such sale shall contain
(i) any provision that would adversely affect in a material manner the
interests of the Banks under the Credit Agreement or the Security Documents
and, notwithstanding the foregoing, to the extent the Banks are required to
disgorge any Net Cash Sale Proceeds paid to them as a result of any
rescission right that a purchaser may have under applicable law with respect
to such sale, then the Obligations that had been deemed satisfied by the
application of such Net Cash Sale Proceeds shall be deemed reinstated and any

                                       2
<PAGE>

security interest in any Collateral that had been released in connection
therewith shall be deemed restored as if such payment had never occurred.

         SS. 3.   TOTAL ACQUISITION COMMITMEnt. Pursuant to the Second
Amendment, the Total Acquisition Commitment was permanently reduced to the
outstanding balance of the Current Acquisition Loans (those outstanding on
November 8, 1999). The Total Acquisition Commitment and the Total Facility
Commitment shall be permanently reduced by the amount of any principal
payments or prepayments received with respect to the Acquisition Loans after
November 8, 1999, whether received heretofore or hereafter.

         SS. 4.   ASSUMPTION OF DEBT BY PCSI. PCSI hereby agrees to assume,
and hereby assumes, joint and several liability with Aztec as a Co-Borrower
with respect to all obligations under the Credit Agreement with respect to a
portion of the Acquisition Loans having an outstanding principal amount of
$15,000,000 on the Effective Date of the Third Amendment. Aztec and PCSI
shall exchange the existing Acquisition Note held by each Bank for (i) an
Acquisition Note signed by Aztec and PCSI as Co-Borrowers in a principal
amount equal to such Bank's respective Commitment Percentage of $15,000,000
and (ii) an Acquisition Note signed by Aztec as Borrower each in a principal
amount equal to such Bank's Acquisition Commitment minus the principal amount
of the Acquisition Note delivered to such Bank pursuant to clause (i) above.
The term "Borrower" shall be deemed to refer to both Aztec and PCSI as it
relates to such portion of the Acquisition Loans assumed by PCSI as
Co-Borrower to the extent appropriate in the context. Any Net Offering
Proceeds with respect to PCSI that are required to be used to repay
Acquisition Loans hereunder, subject to the limitations set forth in Section
4.8.2 of the Credit Agreement (as amended hereby), shall first be applied to
repay Acquisition Loans that have been assumed by PCSI as Co-Borrower until
repaid in full, then to repay other Acquisition Loans. Repayment of the
Acquisition Loans that have been assumed by PCSI as Co-Borrower shall not be
deemed to release PCSI from its obligations under the Guaranty. By signing
below, PCSI shall be deemed to have made all of the representations and
warranties of the Borrower set forth in Section 8 of the Credit Agreement as
of the Effective Date (except that with respect to Section 8.4 and 8.22, PCSI
shall be deemed to make only such portion of such representations and
warranties as relate to PCSI as a Subsidiary of the Borrower). Both Borrowers
and all of the Guarantors (by signing the attached Ratification of Guaranty)
hereby agree that the Guaranty and all of the Security Documents to which
each is a party shall be deemed to secure the Acquisition Notes assumed by
PCSI as Co-Borrower on a PARI PASSU basis with the other Notes. Both
Borrowers agree to make any filings and take any other actions necessary to
ensure that the Acquisition Notes assumed by PCSI as Co-Borrower, as well as
the Acquisition Notes and Revolving Credit Notes of Aztec, are secured on a
PARI PASSU basis by a first perfected security interest in favor of the
Agent, for its benefit and that of the Banks, in all assets of both Borrowers
and all Guarantors, subject only to Permitted Liens.

of the  Credit  Agreement  is  hereby amended as follows:

               (a)     the  definitions of "Borrowing Base" and

the Credit  Agreement is hereby  amended as follows:

                 (a)     Section 2.2 of the Credit  Agreement is hereby
amended by deleting the heading "COMMITMENT FEE" and replacing it with the
heading "COMMITMENT FEE AND OVERADVANCE FEE," by inserting a subheading
"2.2.1. COMMITMENT FEE." after such heading and by adding the following at
the end of such ss. 2.2:

such unpaid fees) or, in the event of a capitalization event (including any
initial public offering of capital stock of PCSI), the Net Offering Proceeds
(to the extent such exceed the amount of such unpaid fees) of such Asset Sale.

                 SS. 7.     AMENDMENT TO SS. 4 OF THE CREDIT AGREEMENT.

                 (a)   Section 4.3 of the Credit Agreement is hereby amended

Borrower shall, immediately upon receipt thereof, pay all outstanding fees
and expenses of the Agent and the Banks, including without limitation any
Overadvance Fees and Amendment Fee required to be paid from such proceeds and

such Subsidiary; with the Total Acquisition Commitment (and/or the Total
Commitment, as applicable) and the Total Facility Commitment also being
permanently reduced by the amount of such prepayment.

         SS. 8.     AMENDMENT  TO SS. 6  OF THE  CREDIT  AGREEMENT.
Section 6.1  of the  Credit  Agreement  is  hereby amended by adding the
following at the end of such ss. 6.1:

Commitment) of the Banks an amendment fee (the "Amendment Fee") equal to the
sum of (i) one percent (1%) of the Total Facility Commitment and (ii) all
unreimbursed expenses of the Agent and the Banks required to be reimbursed by
the Borrower pursuant to the Revolving Credit Agreement. Such Amendment Fee

2000 and the remaining installments due on the first day of each month
thereafter to and including September 1, 2000; provided, however, that in the

amended by  inserting immediately after the end of the text of ss. 9.4(h) the
following:

Borrower will make financial and other appropriate officers of the Borrower
and its Subsidiaries available to the Agent and the Banks for a dial-in
conference call, which will be arranged by the Borrower and of which
arrangements the Borrower shall notify the Agent and the Banks at least one

the foregoing reports or other reports delivered to the Banks by the Borrower
or its Subsidiaries and answer any questions the Agent or the Banks may have

use commercially reasonable efforts to continue to provide reports to the

                 "The Borrower shall continue to maintain the engagement

satisfied in full and (ii) the Revolving Credit Maturity Date."

                 (e)     Section 9 of the Credit  Agreement is hereby
amended by inserting  new ss.ss. 9.20, 9.21, 9.22 and 9.23 immediately after

                 9.20.  PCSI IPO.  The  Borrower  will use  commercially
reasonable  efforts to pursue an initial public offering of the stock of its
Subsidiary Professional Computer Solutions, Inc. ("PCSI"). The Borrower will
obtain the prior written consent of the Agent and each of the Banks for any
initial public offering of the stock of PCSI, which consent shall not
unreasonably be withheld. In the event such consent is granted and such
initial public offering occurs, the Agent, for the benefit of itself and the
Banks, shall continue to have a first priority perfected security interest
with respect to all of the capital stock of PCSI, other than shares sold in
such initial public offering. The Borrower shall pay, or shall cause PCSI to
pay, any unpaid Amendment Fee and any earned and unpaid Overadvance Fees and
other unpaid fees and expenses of the Agent and the Banks from the Net
Offering Proceeds of such offering (including the offering of underwriters'
overallotment shares, if any) and shall use a portion of the remaining Net
Offering Proceeds of such offering (including the offering of underwriters'
overallotment shares, if any), in an amount equal to the greater of (a)
$15,000,000 and (b) 25% of such Net Offering Proceeds, to repay Obligations,
with such amount being applied first to repay Acquisition Notes with respect
to which PCSI and Aztec are jointly and severally liable until paid in full,
then Acquisition Notes of Aztec until paid in full, then Revolving Credit
Notes until paid in full.

                 9.21.  ADDITIONAL  FINANCING.  The Borrower  will use
commercially  reasonable efforts to seek at least $20,000,000 in additional
financing or investment in the form of subordinated debt, preferred stock or
convertible securities. The prior written consent of the Agent and the Banks
shall be required for any such additional financing or investment, whether in
the form of subordinated debt or preferred stock or convertible securities
and the Agent and the Banks may condition such consent upon the use of all of
the first $20,000,000 in Net Cash Sale Proceeds of such additional financing
to repay Obligations. Restrictions on liens in ss. 10.2, restrictions on
indebtedness in ss. 10.1, provisions regarding Restricted Payments in ss.
10.4 and restrictions on amendments to Capitalization Documents in ss. 10.13
contained in this Revolving Credit Agreement shall apply unless specifically
waived in writing by the Agent and the Banks. The holders of any such
subordinated debt, preferred stock or convertible securities shall be
required to enter into a subordination agreement in form and substance
reasonably satisfactory to the Agent and the Banks.

                                       8
<PAGE>

                 9.22. WARRANTS.  As consideration for the Third Amendment,
the Borrower agrees that on each date set forth on the attached SCHEDULE B,
in the event that the Total Facility Commitment is not permanently reduced to
the amount set forth with respect to such date on such SCHEDULE B, the
Borrower shall automatically issue to each of the Banks a warrant to purchase
common stock of the Borrower in the form attached hereto as EXHIBIT I (each a
"WARRANT"), exercisable for the number of Warrant Shares (as defined in the
Warrant) equal to such Bank's PRO RATA share (in accordance with such Bank's
Commitment Percentage of the Total Facility Commitment) of the number of
Warrant Shares that, when combined with the cumulative number of Warrant
Shares for which all Warrants theretofore issued to the Banks would be
exercisable, would equal the percentage of the outstanding shares of the
Borrower's common stock on such date (assuming issuance of all shares of
common stock issuable upon exercise of all outstanding options, warrants and
other rights and upon conversion of all outstanding convertible securities)
set forth on such SCHEDULE B for the respective date, regardless of whether
the Borrower had failed or succeeded in reducing the Total Facility
Commitment to the level set forth on such SCHEDULE B with respect to any
prior date. For purposes of determining whether the Total Facility Commitment
has been permanently reduced to the amount set forth with respect to each
date set forth on SCHEDULE B, amounts in respect of Amendment Fee or
Overadvance Fees paid from proceeds of an Asset Sale (including without
limitation a capitalization event) in advance of the scheduled installment
payment date or Revolving Credit or Acquisition Loan Maturity Date, as
applicable, shall be deemed to have been applied to permanently reduce the
Total Facility Commitment. The Borrower shall enter into a Registration
Rights Agreement with the Banks in form and substance satisfactory to the
Agent and the Banks within fourteen (14) days after the Effective Date. The
Borrower shall be obligated to file on the terms set forth in such
Registration Rights Agreement, within thirty (30) days after the Effective
Date of the Third Amendment, a registration statement with the Securities and
Exchange Commission with respect to the resale of the Warrant Shares by the
Banks and shall use its commercially reasonable efforts to have the
Securities and Exchange Commission prepared to declare such registration
statement effective by June 30, 2000, including filing all amendments
necessary to reflect changes in the Borrower's Circumstances. The Borrower
needs not request acceleration of effectiveness until Warrants have been
issued, at which time the Borrower will use its commercially reasonable
efforts to have the registration statement declared effective. Assuming it
has used its commercially reasonable efforts and continues to do so, the
failure of such registration statement to become effective shall not
constitute a Default or Event of Default under the Credit Agreement or this
Third Amendment. The Borrower will at all times maintain sufficient
authorized but unissued shares of Common Stock reserved for issuance upon
exercise of the Warrants. On the date of issuance of each of the Warrants,
each such Warrant shall have been duly and validly issued to the respective
Bank. The Warrant Shares will be duly and validly issued, fully paid and
nonassessable upon issuance by the Borrower and payment of the exercise price
therefor in accordance with the provisions of the Warrants. Upon exercise of
the Warrants, and the delivery by the Borrower of stock certificates
representing Warrant Shares, all in accordance with the terms of the
Warrants, lawful and valid title to each of such Warrant Shares will be
conveyed to and vested in the Banks, free and clear of all restrictions and
other liens and encumbrances, except the agreements, restrictions and other
liens and encumbrances (if any) imposed by the Third Amendment, the Warrants
and applicable law.

                 9.23.  POSTCLOSING  ITEMS.  The Borrower shall deliver to
the Agent,  within 90 days after the Effective Date of the Third Amendment:
(a) satisfactory evidence that all liens against the assets of the Borrower
and its Subsidiaries other than Permitted Liens have been released and
removed of record, (b) fully executed Pledged Account Agreements in form and
substance satisfactory to the Agent with respect to each depository account
of the Borrower and each of its Subsidiaries, as required by the Second
Amendment and (c) all items required to

                                       9
<PAGE>

be delivered under the Credit Agreement that were not delivered prior to the
Effective Date of the Third Amendment in form and substance satisfactory to
the Agent (provided that the Agent shall deliver to the Borrower a definitive
list of all such items within 30 days after the Effective Date of the Third
Amendment). The Borrower shall deliver to the Agent, within seven days after
the Effective Date of the Third Amendment a revised DISCLOSURE SCHEDULE that
is accurate and complete as of such Effective Date and which DISCLOSURE
SCHEDULE shall contain no information that had such information been known to
the Banks on such Effective Date would have caused any Bank acting reasonably
to have refused to agree to the Third Amendment. The Borrower shall deliver
to the Agent at the time of execution and delivery of the Registration Rights
Agreement, an opinion of counsel reasonably satisfactory in form and
substance to the Agent as to the corporate power and authority of the
Borrower, due authorization, execution and delivery, validity and
enforceability of the Registration Rights Agreement and other customary
provisions. The Borrower shall deliver to the Agent at the time of execution
and delivery of any Warrants, an opinion of counsel reasonably satisfactory
in form and substance to the Agent as to the corporate power and authority
and capitalization of the Borrower, due authorization, execution and
delivery, validity and enforceability of the Warrants and other customary
provisions. The Borrower hereby agrees to pay all reasonable expenses,
including legal fees and disbursements incurred by the Agent and the Banks in
connection with the Third Amendment and the transactions contemplated thereby
and any other expenses, legal fees and disbursements required to be paid
pursuant to ss. 17.1 of the Revolving Credit Agreement for which an invoice
is submitted after the date of the Third Amendment within 30 days after the
date of the respective invoice.

         SS. 10.  AMENDMENT TO SS. 11 OF THE CREDIT  AGREEment.  Section 11
of the Credit Agreement is hereby amended by deleting ss. 11 in its entirety
and restating it as follows:

                  11.1.    CAPITAL  EXPENDITURES.  The  Borrower  will not
make,  or permit any  Subsidiary  of the Borrower  to make,  Capital
Expenditures  in any fiscal  year that  exceed,  in the  aggregate,
$4,000,000.  This covenant shall be tested on the last day of each fiscal
year.

                  11.2. DEBT SERVICE COVERAGE RATIO. The Borrower will not
permit the Debt Service Coverage Ratio to be less than 1.00 to 1.00, tested
on the last day of each fiscal quarter with respect to the fiscal quarter
then ended.

         SS. 11.  AMENDMENT TO SS. 27 OF THE CREDIT  AGREEment.  Section 27
of the Credit Agreement is hereby amended by deleting the second sentence
thereof in its entirety and restating it as follows:

effective date of any waiver by the Majority Banks of the Event of Default
relating thereto), the amount of the Commitments or Acquisition Commitments
of the Banks, the release of all or substantially all of the Collateral, and
