                    SOLICITATION AND REVOCABILITY OF PROXIES

         This Proxy Statement is furnished in connection  with the  solicitation
of proxies by the Board of  Directors of CERBCO,  Inc.,  a Delaware  corporation
("CERBCO" or the  "Company"),  for use at the Special Meeting of Stockholders to
be held at the Holiday Inn, US Air Arena, 9100 Basil Court, Landover,  Maryland,
on Friday,  June 20, 1997 at 10:00 a.m.,  and at any  adjournments  thereof (the
"Meeting").

         At the Meeting, you will be asked to consider and to vote, in person or
by proxy,  for or against  the sale by the  Company of its  two-thirds  stake in
Capitol  Office  Solutions,  Inc.  ("COS")  held by the  Company's  wholly-owned
subsidiary CERBERONICS,  Inc. ("Cerberonics"),  for the consideration of a sales
price of $19 million and  two-thirds  of an  approximately  $5 million  pre-sale
distribution of excess cash from COS (the "Transaction").

         The Board of Directors (the "Board") has fixed the close of business on
April 21, 1997, as the record date (the "Record Date") for the  determination of
stockholders who are entitled to notice of, and to vote at, the Meeting.

         Stockholders are requested to complete,  sign and date the accompanying
proxy and return it  promptly to the Company in the  enclosed  envelope.  If the
enclosed proxy is executed and returned, it may be revoked at any time before it
is voted at the Meeting by a written  notice of  revocation  to the Secretary of
the  Company,  or by  executing a proxy  bearing a later  date,  or by voting in
person at the Meeting.

         Shares of Common Stock and shares of Class B Common  Stock  represented
by valid  proxies  received in time for the Meeting,  and not  revoked,  will be

of common stock will be voted FOR the Transaction; and, if authority is given to
them,  at the  discretion  of the proxy  holders,  on any other matters that may
properly come before the Meeting.

         The  cost of  solicitation  will be borne  by the  Company.  Additional
solicitations  may be made by mail,  telephone,  telegraph,  personal contact or

         This Proxy Statement and form of proxy and the  accompanying  Notice of
Special Meeting, Form 10-K and Form 10-Q are first being mailed to the Company's
stockholders of record on or about April 24, 1997.


                      OUTSTANDING SHARES AND VOTING RIGHTS

         Each share of Common  Stock is entitled to one vote,  and each share of
Class B Common Stock is entitled to ten votes, except with respect to any matter
requiring the vote of Common Stock or Class B Common Stock voting  separately as
a class.  As of the Record Date,  there were  outstanding  ----------  shares of
Common Stock, $.10 par value (the "Common Stock") and ---------- shares of Class
B Common Stock, $.10 par value (the "Class B Common Stock"),  which are the only
classes of stock of the Company  outstanding.  A quorum shall be  constituted by
the presence at the Meeting,  in person or by proxy,  of one-third  (1/3) of the
stock and issued and outstanding and entitled to vote.


                                        1

         Your  vote  is  very  important,  as  approval  of the  Transaction  is
conditioned  upon  the  affirmative  vote of a  majority  of the  votes  cast by
stockholders other than the Company's controlling stockholders (the "Non-Erikson
Stockholders").  The  controlling  stockholders  of the  Company  are  Robert W.
Erikson  and  George  Wm.  Erikson.  As of  the  Record  Date,  the  Non-Erikson
Stockholders held ----------- shares of outstanding Common Stock, entitling them
to cast -----------  votes, and ----------- shares of outstanding Class B Common
Stock,  entitling  them to cast  -----------  votes,  for a total of -----------
votes eligible to be cast by the Non-Erikson Stockholders.

         Approval of the Transaction for purposes of Section 271 of the Delaware
Corporation ("Section 271") Law requires a favorable vote of a majority of votes
entitled to be cast by all the  stockholders  of the  Company.  As of the Record
Date,  the Eriksons  held 117,302  shares of Common Stock and 247,564  shares of
Class B Common Stock, entitling them to cast 2,592,942 votes with respect to the
Transaction,  bringing to  -----------  the total number of votes entitled to be
cast by all stockholders  with respect to the Transaction.  Therefore,  at least
- -----------  affirmative  votes are  required  to approve  the  Transaction  for
purposes  of Section  271.  Provided  that a  majority  of the votes cast by the
Non-Erikson Stockholders are cast in favor of the Transaction, the Eriksons have
agreed  pursuant to the terms of the Transaction to vote  substantially  all (at
least  2,568,486  votes)  of their  shares  in favor  of the  Transaction.  As a
consequence,  the  affirmative  vote  of a  majority  of the  votes  cast by the
Non-Erikson  Stockholders  will result in at least 2,568,487 votes being cast in
favor of the Transaction, an amount in excess of the number of votes required by
Section 271 for approval.


         Since the  Transaction  is  conditioned  on a majority of votes cast by
Non-Erikson Stockholders, votes withheld by Non-Erikson Stockholders,  including
abstentions  and broker  non-votes,  will not be counted as either  votes for or
against the Transaction.  However, for purposes of Section 271, which requires a
favorable  vote  of a  majority  of  votes  entitled  to  be  cast  by  all  the
stockholders  of  the  Company,  votes  withheld  by  Non-Erikson  Stockholders,
including abstentions and broker non-votes, will be counted as votes against the
Transaction.

                           PROPOSAL - THE TRANSACTION


                                     SUMMARY

         The  following  is a summary of  certain  information  relating  to the
Transaction.  This summary is not intended to be a complete description of these
matters and is subject to and qualified in its entirety by reference to the more
detailed information regarding the Transaction described in this Proxy Statement
and contained in the Investment,  Redemption and Stock Purchase  Agreement dated
March 7, 1997, and certain other  agreements  dated as of the same date or to be
entered into in connection with the Transaction, including the Escrow Agreement,
the Erikson Voting Agreement,  the Erikson Consulting and Non-Compete  Agreement
and the Manoogian Executive Agreement,  copies of which are included as Exhibits
A, B, C, D, and E, respectively, to this Proxy Statement. Subject to stockholder
approval and certain other conditions, the Transaction is expected to close (the
"Closing") on or before June 30, 1997.


         The Company's  principal  executive  offices are located at 3421 Pennsy
Drive, Landover,  Maryland 20785, and the Company's phone number at such offices
is (301) 773-1784.  The Company's  stockholders  are urged to read and carefully
consider the entire Proxy Statement.

         The Company has entered into a definitive  Investment,  Redemption  and
Stock  Purchase  Agreement  dated  March 7,  1997 (the  "Redemption  Agreement")
pursuant to which COS will redeem the Company's  entire  two-thirds stake in COS
held   by   the   Company's   wholly-owned   subsidiary,    CERBERONICS,    Inc.
("Cerberonics"),  for approximately $19 million. COS is a provider of copier and
fax  equipment,  service and supplies in the  Washington,  D.C.  and  Baltimore,
Maryland  metropolitan  areas.  Under the  Redemption  Agreement,  the  Company,
through Cerberonics, will also receive a two-thirds share of an approximately $5
million  pre-redemption  distribution of excess cash from COS. The approximately
$22  million  to  be  received  by  Cerberonics   for  the  redemption  and  the
pre-redemption  distribution  will be subject to  adjustment  based upon audited
financial statements at the time of Closing.  After Closing, the Company intends
to declare and distribute  promptly a dividend of $1.50 per share to the holders
of Common  Stock  and  Class B Common  Stock as of a record  date  proximate  to
Closing.

         The Company's  controlling  interest in Insituform East,  Incorporated,
its other principal operating subsidiary which provides excavationless sewer and
pipeline  rehabilitation  services and which is also held  through  Cerberonics,
will not be affected by the Transaction.

         Other parties to the Redemption  Agreement  include Armen A. Manoogian,
President, a director and one-third owner of COS ("Mr. Manoogian"),  and Golder,
Thoma,  Cressey,  Rauner  Fund IV ("GTCR")  of  Chicago,  Illinois.  GTCR is the
controlling  stockholder of Global Imaging Systems,  Inc. of Tampa,  Florida,  a
consolidator of copier dealerships ("Global"). The Redemption Agreement provides
that GTCR and certain other  investors to be named at Closing (the  "Investors")
will  acquire  from Mr.  Manoogian  a portion  (5/8s) of his  current  one-third
interest  in COS for  approximately  $5  million  and  that Mr.  Manoogian  will
participate  ratably  in the $5  million  pre-redemption  distribution  by  COS.
Pursuant to the Redemption Agreement,  the Investors are to acquire newly issued
COS common stock in  consideration  of a $1 million  investment,  and GTCR is to
arrange the  additional  estimated $24 million  financing  that COS will need to
fund the redemption of COS stock held by  Cerberonics  and purchase of COS stock
from Mr. Manoogian. After such redemption and stock purchase, the Investors will
have a two-thirds  interest and Mr. Manoogian will have a one-third  interest in
the recapitalized and newly leveraged COS.

         For the  Transaction,  the  parties  assigned a value of $27 million to
COS,  excluding the approximately $5 million  pre-redemption  distribution.  The
Company's  $19 million  share of the total $27  million  value is  comprised  of
two-thirds  of the total  valuation  ($18  million),  plus a $1 million  control
premium in light of the Company's controlling interest in COS. Consequently, Mr.
Manoogian's minority interest is being valued at

                                        4

<PAGE>



$8 million, exclusive of his one-third interest in the $5 million pre-redemption
distribution. The Investors are to acquire 5/8 of that interest for $5 million.

         The  Redemption  Agreement  provides  that COS and each of the Eriksons
will enter into a three year consulting and  non-competition  agreement pursuant
to which the Eriksons are to serve as advisors and  consultants to COS after the
Transaction.  The Eriksons are each to receive $150,000 for the  non-competition
agreement  and $50,000 for  consulting  services  promptly  after  Closing,  and
$50,000 on each of the first and second anniversaries  thereof, if available and
able to perform the consulting  services.  Similarly,  the Redemption  Agreement
provides  that COS and Mr.  Manoogian  will  enter into an  Executive  Agreement
pursuant  to which  Mr.  Manoogian  will  serve as the  President  of COS  after
Closing,  at an initial  annual  base  salary of  $200,000  (subject to periodic
increase at the discretion of the COS Board),  with the potential for earning an
annual bonus of up to one-half of his annual base salary beginning in the fiscal
year ending June 30, 1998.

         The Transaction is conditioned,  among other things, upon the Company's
receipt from an investment  banker of an opinion stating that the  consideration
to be received for the sale of the Company's  two-thirds stake in COS is fair to
the  Company  from a  financial  point of view.  As a  consequence,  the Company
retained  Merrill Lynch  Business  Advisory  Services  ("MLBAS"),  a division of
Merrill Lynch, Pierce,  Fenner & Smith Incorporated,  to render an opinion as to
the  fairness  to  the  Company,   from  a  financial  point  of  view,  of  the
consideration  to  be  received  by  Cerberonics   pursuant  to  the  Redemption
Agreement.  At a meeting of the Board held on April 3, 1997, MLBAS delivered its
oral  opinion to the Board to the effect that the proposed  consideration  to be
received by  Cerberonics  pursuant to the  Redemption  Agreement was fair to the
Company from a financial point of view and  subsequently  confirmed such opinion
by delivery of its written  opinion dated as of April 4, 1997.  The full text of
MLBAS's opinion dated as of April 4, 1997, which sets forth, among other things,
assumptions made, procedures followed, matters considered and limitations on the
scope of review  undertaken is attached as Exhibit F to this Proxy Statement and
is incorporated  herein by reference.  The Company's  stockholders  are urged to
read the MLBAS opinion in its entirety.

         The  Transaction is also  conditioned  upon the separate  approval by a
majority of the votes cast by the Eriksons,  and by a majority of the votes cast
by the  Non-Erikson  Stockholders.  In connection  therewith,  the Eriksons have
entered  into a voting  agreement  pursuant to which each of them agrees to vote
substantially all of the shares of the Company's Common Stock and Class B Common
Stock held by each of them in favor of the  Transaction,  provided a majority of
the  votes  cast by the  Non-Erikson  Stockholders  are  voted  in  favor of the
Transaction.  As of the Record Date, the Non-Erikson Stockholders held shares of
outstanding  Common  Stock,   entitling  them  to  cast  votes,  and  shares  of
outstanding  Class B Common Stock,  entitling them to cast votes, for a total of
votes eligible to be cast by the Non-Erikson Stockholders.

         The  Company  acquired  its  two-thirds  stake  in COS in  1987  for an
investment of $500,000.  The Company also loaned COS $2.75  million,  which loan
was subsequently repaid by COS with interest.  Though COS struggled early on, in
recent years COS has performed  well,  contributing  on average in excess of 20%
pre-tax earnings on revenues during the last three years.

         In recent years, there has been an accelerated  consolidation of copier
dealers  nationwide,  principally by IKON Office  Solutions,  Inc.  ("Ikon") and
Danka Business  Systems,  PLC.  ("Danka"),  and more recently by Global.  Public
reports indicate that Ikon and Danka both have grown via industry  consolidation
to sales volumes in excess of $3 billion each.

         As a result of the industry  consolidation,  the Board expects that COS
will face  increasing  and  intensifying  competition  from these large national
networks,  each of which have the benefit of substantially  larger marketing and
distribution  resources,  and potential  preferential pricing from manufacturers
via higher volume purchasing levels, resulting in the risk for decreases in COS'
pre-tax margins.  The Board believes that the present strong performance of COS,
taken  together  with  the  continuing  industry  consolidation,  makes  this  a
favorable time for the Company to sell its interest in COS.

         Over the last three years, the Company received expressions of interest
from Ikon and Danka, the industry's two principal  consolidators,  regarding the
possible  sale of COS,  but  neither  company  appeared  willing  to pay a price
acceptable to the Board.

         Global first  approached the Company in October of 1994 about acquiring
COS,  and the Company  engaged in three  separate  rounds of  negotiations  with
Global  since that date.  The first round was  terminated  in March of 1995 when
Global lost its planned source of financing. The price then under discussion was
$24  million  for 100% of COS.  Global  approached  the Company a second time in
December of 1995,  again offering a $24 million  purchase price.  The issue of a
control premium for the Company was unresolved, and the Board then felt that the
purchase price was inadequate.

         The third round commenced in March of 1996 when Global made yet another
approach.  Over the next eight months,  basic terms generally  acceptable to the
Company were agreed upon. The price to the Company increased from $16 million to
$19 million  reflecting  both an  increased  transaction  value and a $1 million
control  premium  to the  Company.  Concerns  about  Global's  ability to obtain
financing  were  resolved  by  the  substitution  of  GTCR,  Global's  principal
stockholder, as the buyer. But significant unresolved issues remained.

         The Board desired to obtain an investment  banker's  opinion  regarding
the  fairness  of  the  price  prior  to  executing  the  Redemption  Agreement.
Ultimately  the  Company  agreed  to obtain  the  opinion  after the  Redemption
Agreement  was  executed  and to pay a break-up  fee of  $250,000 if the Company
terminated the Transaction as a result of an unfavorable opinion.

         During negotiations GTCR requested that the Eriksons enter into and the
Eriksons  ultimately  agreed to enter into a voting agreement  pursuant to which
they agreed to cast substantially all their votes in favor of the Transaction so
long as a majority of all votes cast by the Non-Erikson  Stockholders  were cast
in favor of the Transaction. The Eriksons objected to the extent that the voting
agreement  required them to give up certain rights related to their stock for an
extended period,  including "no shop" provisions and a prohibition on selling or
pledging their stock,  among other things.  The Eriksons asked for  compensation
from the  Company in the amount of $300,000  each for giving up these  rights in
furtherance of the  Transaction.  The Board was concerned about the reduction in
the net proceeds  from the  Transaction  if it paid this amount to the Eriksons.
Ultimately,  GTCR agreed to pay the Eriksons,  without  reducing the proceeds to
the Company,  a total of $300,000  each for agreeing not to compete with COS and
for providing  consulting services to COS for three years following Closing. The
Company  agreed to  reimburse  the Eriksons as  stockholders  for their costs in
reviewing and negotiating the voting  agreement and to indemnify the Eriksons as
stockholders in connection with the Transaction.

         Because  GTCR's  request  for  the  Eriksons  to  enter  into a  voting
agreement   raised   issues   involving  the  Eriksons   personally,   including
indemnification   as   stockholders,   and  because  the  Redemption   Agreement
contemplates  the  Eriksons  entering  into  a  consulting  and  non-competition
agreement  through which they are to receive  compensation,  the Board  believes
that it is appropriate  for the  Non-Erikson  Stockholders  to have a meaningful
voice in approving the  Transaction.  Ultimately GTCR agreed that the Redemption
Agreement would provide that the Transaction would not be deemed approved unless
a majority of all votes cast by the Non-Erikson  Stockholders were cast in favor
of the Transaction,  provided that the Company will pay a $250,000  break-up fee
if the stockholders fail to approve the Transaction.

THE BOARD OF DIRECTORS  BELIEVES THAT THE TRANSACTION IS FAIR TO AND IN THE BEST
INTEREST OF THE COMPANY.  THE BOARD OF DIRECTORS  HAS  UNANIMOUSLY  APPROVED THE
TRANSACTION AND RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE TRANSACTION.

General

         Holders  of the  Company's  Common  Stock and Class B Common  Stock are
being  asked to  consider  and to  approve  the  Transaction.  The  terms of the
Transaction  are set  forth in the  Redemption  Agreement  and  certain  related
agreements  entered  into in  connection  therewith.  The  Redemption  Agreement
provides  for (i) the $19  million  redemption  by COS of the entire  two-thirds
equity  interest  of  COS  held  by  Cerberonics,   the  Company's  wholly-owned
subsidiary, in conjunction with the recapitalization of COS, (ii) payment to the
Company of a  two-thirds  share of an  approximately  $5 million  pre-redemption
distribution  of excess cash from COS,  (iii) the  arrangement of $24 million in
additional  financing for COS,  (iv) a $1 million  investment in COS by GTCR and
the  Investors,  and (v) the purchase for $5 million by the Investors from Armen
A. Manoogian ("Mr.  Manoogian") of a majority of the remaining  one-third equity
interest of COS held by Mr. Manoogian.  The Redemption Agreement was executed on
March 7, 1997, subject to stockholder approval and certain other conditions. The
Transaction is expected to close on or before June 30, 1997.

Background and Reasons for the Transaction

         During 1987 the Company was phasing out of defense work and was looking
for new  opportunities.  In October of that year,  the  Company  joined with Mr.
Manoogian in the  acquisition of COS for a purchase  price of $3.5 million.  The
Company invested  $500,000 for its ultimate  two-thirds share, and Mr. Manoogian
invested  initially  and upon later  exercise  of an option  $250,000  to end up
owning the other  one-third.  The Company loaned COS the remaining $2.75 million
to complete the leveraged  buy-out,  which loan was  subsequently  repaid by COS
with interest.

         Though COS  struggled  somewhat in the early years after the  Company's
investment, financial performance improved gradually until COS became the strong
performer  that it is today.  COS has now  delivered on average in excess of 20%
pre-tax earnings on revenues during the last three years.

         Mr.  Manoogian  has been the  President  of COS since  October of 1987.
Throughout  this  period,  Mr.  Manoogian,   as  well  as  the  Eriksons,   have
participated  in the Copier  Dealers  Association  to help them stay informed of
developments  in the copier market.  Through this  connection,  and the numerous
copier business owners and  professionals it has enabled them to meet, they have
acquired  information  about the performance and valuation of copier  businesses
and have observed a substantial consolidation of copier dealers,  principally by
Danka or Ikon, both of which are public companies with annual sales in excess of
$3 billion.  Available information shows that Danka has acquired over 100 copier
business over the last three years, and in calender 1996 alone Ikon has acquired
in excess of 80 copier businesses.

         As a result of the industry  consolidation,  the Board expects that COS
will face  increasing  and  intensifying  competition  from these large national
dealer  networks  owned by Ikon and  Danka,  both of which  have the  benefit of
substantially  larger  marketing  and  distribution  resources,   and  potential
preferential  pricing  from their  manufacturers  via higher  volume  purchasing
levels resulting in the risk for decreases in COS' pre-tax margins.


                                        7

         The Board  believes that the present  strong  performance of COS, taken
together with the continuing industry consolidation, makes this a favorable time
for the Company to sell its interest in COS.

         The lead buyer, GTCR, is the controlling stockholder of Global, a third
nationally recognized  consolidator in the copier industry. The Company believes
GTCR views COS as a highly profitable  business with a prestigious  product line
located in the fourth  largest  market in the  country,  making COS an important
addition to its growing national portfolio of copier businesses.

         Additionally,  because  the  Transaction  is  structured  such that Mr.
Manoogian  will  sell  only a portion  of his COS  stock  and will  remain  COS'
President,  GTCR will have the benefit of his industry experience and management
skills after Closing.

Certain Material Negotiations

         Ikon  first  approached  the  Company  in July of 1993 to  explore  the
Company's  willingness  to sell COS.  The Board  considered  Ikon's offer of $12
million for 100% of COS to be inadequate,  and nothing further developed at that
time.  Ikon  approached  the  Company  again in the spring of 1994 with an offer
substantially  similar to its first.  The Board  still  believed  that the price
offered was inadequate, particularly in light of the then recent improvements in
COS' profitability.

         In the fall of 1993, a Danka  representative  informally  contacted Mr.
Manoogian to explore whether there was an interest in selling COS. General price
ranges were discussed,  but they were unable to find sufficient common ground to
continue  discussions.  Danka contacted Mr. Manoogian again in the fall of 1996,
suggesting  that it may be  willing  to  acquire  100% of COS for a price in the
range of $20-$22 million.  Nothing developed from these discussions  because the
contemplated price was well below a $24 million price proffered by Global.

         Global  approached the Company about acquiring COS in the fall of 1994,
and  offered to  purchase  100% of COS stock for $24  million.  Though the Board
believed such price might fall within an  acceptable  range,  certain  essential
issues were not  resolved.  Among other things,  Mr.  Manoogian was unwilling to
accept anything other than a pro rata split of the sales proceeds,  which failed
to accord the Company any value for its control  position.  During the course of
discussions,  Global  advised the Company that it had lost its planned source of
financing and negotiations were subsequently discontinued.

         In March of 1995, Mr. Manoogian offered to purchase the Company's share
of COS for $16 million.  This was  equivalent to Global's  offer,  but similarly
failed  to  provide a control  premium  for the  Company  and  lacked  committed
financing. Nothing further developed in connection with that offer.

         In December of 1995, Global approached the Company a second time, again
offering a $24 million  purchase price and claiming new  financing.  The control
premium issue  remained  unresolved,  and the Board felt that the purchase price
had become  inadequate  in light of improved  earnings and growth  possibilities
available  to COS as a  result  of its  recent  expansion  into  the  Baltimore,
Maryland market. In addition, questions remained about the certainty of Global's
new financing, and discussions were suspended.

         In March of 1996,  Global  made a new  offer  to  purchase  COS,  which
commenced the round of negotiations  that ultimately led to the execution of the
Redemption  Agreement  one year  later.  The new  offer  for  100% of COS  stock
consisted  of  $16  million  to  the  Company,  $8  million  to  Mr.  Manoogian,
distribution  of COS' cash in  excess  of  $800,000  and  $1.75  million  to the
Eriksons  for  income  continuation/consulting  over  seven  years.  Global  was
informed  that  (i) the  purchase  price  was now  inadequate  considering  COS'
improved earnings,  (ii) the offer accorded the Company no control premium,  and
(iii) Global  would have to  adequately  prove its ability to obtain  financing.
Further,  the  Eriksons  would not discuss any  possible  payments to them while
Global was negotiating the sales price with the Company.

         Over the next eight months, these issues were resolved. The transaction
value of COS was  increased to $27  million,  and Mr.  Manoogian  agreed to a $1
million control premium for the Company, resulting in $19

                                        8

<PAGE>



million to the Company for its two-thirds interest. Mr. Manoogian also agreed to
accept $5 million for five- eighths of his one-third  interest and to retain the
remainder of his  interest,  thus  limiting the buyer's  required  investment to
approximately  $24 million.  Finally,  to ensure  committed  financing  Global's
principal stockholder, GTCR, was substituted as the buyer.

         On  December 5, 1996,  the Board  convened to discuss the status of the
negotiations.  A draft of the  proposed  agreement  prepared  by GTCR was  under
review by Company  counsel,  but there were a number of  significant  unresolved
issues.  To  further  assure  itself  that the  price  under  consideration  was
appropriate and fair to the Company,  the Board determined that it was desirable
for the Company to have the  Transaction  reviewed by an independent  investment
banking  firm.  The Board  directed the officers to contact  investment  banking
firms to  determine  availability  and cost of a fairness  opinion and  directed
counsel  to inform  GTCR that the  Company  desired  to  obtain  advice  from an
investment banker before proceeding further.

         At the  December 5 meeting,  counsel  advised  the Board that  although
Delaware  corporation  law probably  required a stockholder  vote to approve the
proposed transaction, the Erikson votes alone would be enough for such approval.
Because GTCR's request for the Eriksons to enter into a voting  agreement raised
issues involving the Eriksons personally,  the Board considered whether it might
be appropriate for the Non-Erikson Stockholders of each class of stockholders to
have a meaningful  voice in approving the Transaction.  That voting  requirement
was later modified to provide that the Transaction  would not be deemed approved
unless a majority of all votes cast by the Non-Erikson Stockholders were cast in
favor of the  Transaction,  with the  holders  of  Class B  Common  Stock  being
accorded  the  required  and usual ten votes per  share.  This  requirement  was
acceptable to GTCR, and is an integral part of the  Transaction as now presented
to the stockholders.

         At a meeting on December 16, 1996, the Board reviewed the status of the
search  for  an  investment   banker,  and  discussed  various  aspects  of  the
Transaction, including GTCR's insistence on a $1 million breakup fee.

         On January 7, 1997, GTCR informed the Company that, given the length of
time that the parties had been  negotiating,  GTCR would  withdraw  its proposal
unless the Company signed a definitive  agreement prior to the Company retaining
an investment bank. GTCR also insisted that any compensation arrangement with an
investment  bank not be  contingent  on the  success of this or any  alternative
transaction.

         The Board convened to discuss this development on January 15, 1997. The
Board felt that as a one-third  stockholder  of COS as well as its President for
the last nine years,  and as an employee of Xerox for  seventeen  years where he
rose  to a  Senior  Marketing  Executive  level,  Mr.  Manoogian  could  provide
additional  reliable  information  regarding  the  fairness  of the price  under
consideration.

         Mr. Manoogian reported orally and in a followup  memorandum that copier
dealers like COS typically  sold for cash at five to six times  earnings  before
interest and taxes ("EBIT") and  approximately  40% to 50% of sales revenue.  By
comparison,  the price  offered  for COS by GTCR was six times  EBIT and 134% of
sales revenue.  Mr. Manoogian's report further confirmed the Board's belief that
the price under consideration was appropriate.

         The  Board  faced  the  choice  of  risking  the  possible  loss of the
prospective  sale by insisting  upon a fairness  opinion  before  approving  the
transaction,  or of risking an unfavorable fairness opinion after execution of a
binding  agreement.  Given GTCR's position on the timing of an investment banker
opinion,  the Board  determined  that it had  sufficient  information  about the
fairness of the price to place a modest  break-up fee at risk pending receipt of
a formal  fairness  opinion.  The Company  then  offered  GTCR a break-up fee of
$250,000 in the event that the Company terminated the transaction as a result of
an  unfavorable  investment  banker  opinion  obtained  after  execution  of the
Redemption Agreement. GTCR ultimately agreed to this amount.

         The initial draft of the proposed Redemption Agreement prepared by GTCR
and transmitted to the Company in November 1996 included a requirement  that the
Eriksons execute a voting agreement requiring

                                        9

<PAGE>



them to vote their shares in favor of the transaction.  GTCR provided a draft of
the proposed  voting  agreement in early  December of 1996.  Upon reviewing this
draft,  the  Eriksons  were  concerned  with the  extent to which the  agreement
required them to give up certain  rights related to their Common Stock and Class
B Common Stock for the entire period from execution of the Redemption  Agreement
until closing of the  transaction.  Specifically,  the Eriksons were  personally
being asked to execute an agreement  which contained a "no shop" provision which
would prohibit or restrict  during the pendency of the transaction the Eriksons'
ability to sell or pledge  their  stock or to  solicit a sale of their  stock to
anyone other than GTCR, would require that they vote their stock in favor of the
transaction  and/or  grant  GTCR an  irrevocable  proxy to vote the  stock  with
respect to the  transaction,  and would  commit the  Eriksons to  recommend  the
transaction to the Non-Erikson Stockholders.

         Although the Eriksons believed that the proposed transaction was in the
Company's  best  interest,  they also felt that the  proposed  voting  agreement
required  them   individually   to  forfeit   valuable   rights  as  controlling
stockholders  of the Company and might subject them personally to certain risks,
including  the risk of  litigation.  They  believed  that they could  personally
suffer a  considerable  financial  detriment as a result of the  prohibition  on
marketing  their  stock of the  Company,  the  value of which  might  rise  upon
announcement  of the  transaction.  They  also  felt  that  the  timing  of this
prohibition on selling their stock was  inopportune,  as the Eriksons may desire
to sell some of their stock to fund a potentially  substantial obligation to the
Company  stemming  from a judgment in certain  litigation  (currently on appeal)
arising from the  Erikson's  1990 attempt to effect a sale of their  controlling
interest in the Company to Insituform Technologies, Inc. The Eriksons noted that
no other  stockholders  would be required to agree to such restrictions on their
stockholder rights.

         To help the Eriksons measure the financial detriment they might suffer,
the Eriksons  engaged  Puglisi & Associates to determine the cost of put options
on the Eriksons  shares of the Company's stock at a series of exercise prices if
those put  options  were  part of a  protective  put  strategy  employed  by the
Eriksons.  Using the  Black-Scholes  Option Pricing Model,  Puglisi & Associates
determined  that the cost of put options on the Erikson's  stock purchased for a
ninety-day  period would be between  $427,000 (at the then current market price)
and  $960,000  (at a market  price of $14.00).  The cost would be greater if the
options extended for a longer period.

         At a Board meeting on January 15, 1997, citing the Puglisi & Associates
analysis,  the Eriksons  asked the Company to  compensate  them in the amount of
$300,000 each for agreeing to enter into the voting agreement. The Eriksons also
asked for  indemnification for any suits brought against them as stockholders in
connection  with  the  transaction  and for  their  attorney  fees  incurred  in
connection with  negotiating a voting  agreement.  Although the Board understood
the Eriksons' concerns, it was concerned about the reduction in the net proceeds
of the  transaction  to the  Company  if the  Company  paid  this  amount to the
Eriksons.

         At the same  meeting  and  after  considerable  discussion,  the  Board
directed  counsel  to ask GTCR to either (i)  eliminate  the  requirement  for a
voting  agreement  in  exchange  for the Company  agreeing to a break-up  fee of
$250,000  in the  event  of an  unfavorable  investment  banker  opinion  or the
Company's  stockholders not approving the transaction,  or (ii) pay the Eriksons
the  $600,000 out of GTCR funds.  GTCR  subsequently  offered to  eliminate  the
voting  agreement  entirely,  but only if the  break-up  fee amount  remained at
$500,000 for the stated events.

         The Board  discussed  GTCR's offer at a meeting on January 20, 1997. At
that  time,  the  Eriksons  informed  the Board  that  given  the  course of the
negotiations  and their  obligations as directors and controlling  stockholders,
including insider trading restrictions and requirements to disclose their voting
intentions,  they  believed  their rights as  stockholders  might be impaired or
restricted even if the transaction  proceeded without the voting agreement,  and
without  compensation.  The Eriksons further informed the Board that there was a
possibility  that the  Eriksons  could  ultimately  decide to vote  against  the
transaction  as  stockholders,  after  voting  in  favor of the  transaction  as
directors.

         At a meeting  on  January  23,  1997,  the Board  determined  that with
respect to any matter in connection  with the possible sale of COS for which the
Company's counsel advised the Eriksons could be considered interested, a special
committee consisting of Messrs. Kincheloe and Hayes, as disinterested directors,
would

                                       10

<PAGE>



determine the Company's position. After conferring separately, Messrs. Kincheloe
and Hayes  determined  and the Board  resolved  that the Company  should offer a
break-up  fee of  $500,000  in the  event of an  unfavorable  investment  banker
opinion  or  disapproval  by the  Non-Erikson  stockholders,  but to  propose no
break-up fee in the event that the Eriksons did not approve the  transaction  as
stockholders.

         Further negotiations and consideration of the Board's most recent offer
resulted in GTCR making a proposal on January 27, 1997.  GTCR suggested that COS
would  benefit from  engaging the  Eriksons as  consultants  for a period of two
years and for the Eriksons  agreeing not to compete with COS. GTCR then proposed
compensation  to each of the  Eriksons of $150,000  per year for two years for a
consulting and non-compete agreement (later changed to three years with $150,000
paid to each promptly after Closing for non-compete, $50,000 each promptly after
Closing for consulting  services,  and $50,000 each for  consulting  services on
each of the first and second anniversaries  thereafter, if available and able to
provide  consulting  services).  GTCR further  proposed (i) a return to a voting
agreement with the Eriksons with no compensation, (ii) a breakup fee of $250,000
in the event of an unfavorable  investment  banker opinion or disapproval by the
Non-Erikson  Stockholders,  and (iii) an increase in the minimum cash to be left
in COS at closing from $800,000 to $1.2 million.

         This  proposal was  considered by the Board at a meeting on January 30,
1997.  As a  result  of  the  reinstatement  of  the  requirement  for a  voting
agreement,  the  Eriksons  again  asked to be  indemnified  as  stockholders  in
connection  with the  transaction,  and to be reimbursed for their legal fees in
drafting  and  negotiating  the voting  and,  consulting  agreements.  The Board
discussed the Eriksons'  request and was amenable to the Eriksons' request as to
the voting  agreement so long as legal counsel could be satisfied with the terms
of the indemnification.  (See "Related Agreements -- Erikson Voting Agreement").
Messrs.  Kincheloe  and Hayes met  separately,  then again with the full  Board.
While the Board felt that GTCR's proposal was satisfactory in most respects,  it
did not find satisfactory the increase in minimum cash left in COS from $800,000
to $1.2 million,  as it was  equivalent to decreasing  the purchase price to the
Company by $400,000.  While  meeting  separately,  Messrs.  Kincheloe  and Hayes
contacted Mr.  Manoogian and advised him the Board strongly opposed reducing the
sales  price and that he and GTCR  could not reduce the  Company's  proceeds  to
offset all or part of what COS would pay the  Eriksons  for the  consulting  and
non-competition  agreement.  The  meeting  ended  without a formal  decision  on
whether to accept or reject GTCR's most recent proposal.

         After  considering  the  Company's  concerns,  on February 3, 1997 GTCR
offered to drop the cash requirement back to $800,000, thus offering the Company
the full price that it had  negotiated;  and with a voting  agreement as part of
the transaction,  it was also clear that the Eriksons would vote in favor of the
transaction  as  stockholders  so  long as  there  is an  affirmative  vote of a
majority of votes cast by the Non-Erikson  Stockholders.  Counsel then proceeded
to  negotiate  the  terms of the  various  ancillary  documents  concerning  the
Transaction.

         By March 6, 1997, it appeared to counsel for the Company that all terms
of the proposed  transaction were satisfactory to the Company. On March 7, 1997,
the Board met to consider the Transaction in the final form  represented in this
Proxy Statement,  and found it to be in a form sufficient for  recommendation to
the Company's stockholders. The Board then voted to approve the Transaction.

Fairness Opinion

         At the April 3, 1997  meeting  of the  Board,  Merrill  Lynch  Business
Advisor  Services,  a  division  of  Merrill  Lynch,  Pierce,  Fenner  and Smith
Incorporated ("MLBAS') delivered its opinion to the Board to the effect that, as
of such date, the proposed  consideration to be received by Cerberonics pursuant
to the  Redemption  Agreement  was fair  from a  financial  point of view to the
Company.  MLBAS subsequently delivered to the Board its written opinion dated as
of April 4, 1997 to the foregoing effect.

         The full text of MLBAS's opinion dated as of April 4, 1997,  which sets
forth,  among other  things,  assumptions  made,  procedures  followed,  matters
considered,  and limitations on the scope of review  undertaken,  is attached as
Exhibit F to this Proxy Statement and is incorporated herein by reference. The

                                       11

Company's stockholders are urged to read the MLBAS opinion in its entirety. This
summary of the opinion of MLBAS set forth in this Proxy  Statement  is qualified
in its entirety by reference to the full text of such opinion.

         MLBAS'S  OPINION IS DIRECTED TO THE  COMPANY'S  BOARD OF DIRECTORS  AND
ADDRESSES  ONLY  THE  FAIRNESS,   FROM  A  FINANCIAL   POINT  OF  VIEW,  OF  THE
CONSIDERATION  TO  BE  RECEIVED  BY  CERBERONICS   PURSUANT  TO  THE  REDEMPTION
AGREEMENT.  THE OPINION  DOES NOT ADDRESS THE  UNDERLYING  BUSINESS  DECISION TO
PROCEED WITH THE TRANSACTION AND DOES NOT CONSTITUTE, NOR SHOULD IT BE CONSTRUED
AS, A  RECOMMENDATION  TO ANY HOLDER OF THE  COMPANY'S  COMMON  STOCK OR CLASS B
COMMON  STOCK AS TO HOW  SUCH  STOCKHOLDER  SHOULD  VOTE AT THE  MEETING  ON THE
TRANSACTION OR ANY OTHER MATTER IN CONNECTION THEREWITH.

         In arriving at its opinion, among other things, MLBAS has: (i) reviewed
the Redemption  Agreement and the proposed  financial terms of the  Transaction;
(ii) reviewed audited financial information for the five fiscal years ended June
30,  1992  through  1996 for the  Company  and  COS,  as well as  various  other
unaudited  financial  information  for the Company and COS;  (iii) compared COS'
historical  results of operations  with that of certain public  companies  which
MLBAS considered  relevant for its analysis;  (iv) visited COS' headquarters and
conducted  discussions  with COS' senior  management  concerning the history and
past  performance  of COS' current  business  operations,  and reviewed  certain
forecasts  provided to MLBAS in the course of such  discussions  relating to the
business,  earnings,  cash flow,  assets and prospects of COS; (v) reviewed such
other financial studies and analyses and performed such other investigations and
took  into  account  such  accepted  financial  and  valuation   procedures  and
considerations  and such other matters as MLBAS deemed  relevant,  including its
assessment of general and local economic,  market and financial conditions which
have an impact on the industry in which COS operates.

         While  MLBAS  reviewed  the  financial  terms of  certain  transactions
involving  the  acquisition  of  companies  in  industries  comparable  to  COS'
operations,  MLBAS did not identify a  sufficient  number of  acquisitions  with
adequate available  information that it deemed to be relevant for the purpose of
its analysis and,  accordingly,  did not  undertake  any analysis  comparing the
financial terms of the Transaction with other acquisitions.

         In preparing its opinion, MLBAS relied on the accuracy and completeness
of all financial and other  information  supplied or otherwise made available to
it by the  Company  and  COS,  or  which  are  publicly  available,  and did not
independently  verify such information or undertake an independent  appraisal or
valuation of the assets or  liabilities  of COS.  With respect to any  financial
forecasts and projected  expense  reductions  provided to MLBAS by and discussed
with COS' management,  MLBAS assumed that such financial forecasts and projected
expense reductions  (together with the assumptions and bases therefor) have been
reasonably  prepared  and reflect the best  currently  available  estimates  and
judgment of COS' management as to the expected future  financial  performance of
COS.

         MLBAS's  opinion  is also  given on the  assumption  that  there are no
undisclosed or unexpected conditions which would affect the value of COS' assets
or the financial condition or operations of COS or the expected future financial
performance of COS. MLBAS's opinion is necessarily based upon market and general
economic conditions existing as of the date of its opinion.

         The terms of MLBAS's engagement are limited to expressing an opinion as
to whether  the  consideration  to be received  by  Cerberonics  pursuant to the
Redemption  Agreement is fair to the Company from a financial  point of view and
MLBAS was not  requested to assist and did not  participate  in  structuring  or
negotiating the terms of the Transaction.  In addition, MLBAS's opinion does not
address  the  relative  merits  of  the  Transaction  and  alternative  business
strategies involving COS, including the sale of COS to third parties.

         In connection  with  rendering  its opinion,  MLBAS  performed  certain
financial analyses,  consisting of those summarized below. The summary set forth
below does not purport to be a complete description of the analyses performed by
MLBAS in this regard,  although it describes all material analyses  performed by
MLBAS. The preparation of a fairness opinion involves various  determinations as
to the most appropriate and relevant

                                       12

<PAGE>



methods  of  financial  analysis  and the  application  of these  methods to the
particular  circumstances  and,  therefore,  such  an  opinion  is  not  readily
susceptible  to  a  partial  analysis  or  summary   description.   Accordingly,
notwithstanding  the separate factors  summarized below, MLBAS believes that its
analyses must be considered in their entirety and that selecting portions of its
analyses and factors  considered  by it,  without  considering  all analyses and
factors,  or attempting to ascribe relative weights to some or all such analyses
and  factors,  could  create  an  incomplete  view  of  the  evaluation  process
underlying MLBAS's opinion.

         In  performing  its  analyses,  MLBAS made  numerous  assumptions  with
respect to industry  performance,  general business and economic  conditions and
other  matters,  all of which are beyond the  control of MLBAS,  the Company and
GTCR. The analyses  performed by MLBAS are not necessarily  indicative of actual
values  or  actual  future  results,  which  may be  significantly  more or less
favorable  than  suggested by such  analyses.  In addition,  the analyses do not
purport to be  appraisals or to reflect the prices which may be obtained for COS
or its  securities  or assets at the present  time or at any time in the future.
Such analyses were prepared  solely as part of MLBAS's  analysis of the fairness
of the  consideration  to be received by Cerberonics  pursuant to the Redemption
Agreement  and were  provided to the Board in  connection  with the  delivery of
MLBAS's opinion.  With respect to the comparison of selected  companies analysis
summarized  below,  no public company  utilized as a comparison,  of course,  is
identical to COS and such analyses  necessarily  involve complex  considerations
and   judgments   concerning   the   differences   in  financial  and  operating
characteristics  of the companies and other factors that could affect the public
trading values of the companies concerned.

         The following is a summary of the material analyses  presented by MLBAS
to the Board in connection with its April 3, 1997 opinion.

         Discounted  Cash Flow Analysis.  MLBAS  performed  discounted cash flow
analyses  (i.e., an analysis of the present value of the projected cash flows of
the periods and at the discount  rates  indicated)  for COS based on projections
prepared using  assumptions  supplied by COS'  management of COS' net cash flows
for the period commencing on December 31, 1997 through June 30, 2006, inclusive,
using  discount  rates ranging from 16% through 18%,  inclusive,  and a terminal
multiple of  earnings  before  interest  and taxes of 8x.  MLBAS's  calculations
indicated a range of values based on  discounted  cash flows of $28.7 million to
$24.8 million, without giving effect to potential synergies that may result from
the Transaction.  After giving effect to such potential synergies, as well as to
COS' available cash,  outstanding debt and off-balance sheet liabilities,  MLBAS
estimated an indicated  range of values based on a discounted cash flow analysis
of $32.0 million to $27.7 million.

         Comparison of Selected  Companies.  MLBAS reviewed and compared certain
ratios and public market multiples  relating to publicly available data compiled
by Institutional Brokers Estimate System for a group of selected companies which
MLBAS deemed to be relevant,  consisting  of Danka  Business  Systems PLC,  IKON
Office Solutions,  Inc., Pitney Bowes, Inc. and Xerox Corp.  (collectively,  the
"COS Selected  Companies").  Based on a review of such  information  for the COS
Selected  Companies,  MLBAS determined that the relevant range based on the mean
and median for the latest  twelve months  available  earnings  before  interest,
taxes, depreciations and amortization ("LTM EBITDA") to be 12.3x to 13.7x.

         MLBAS then observed that as a result of, among other  factors,  (i) the
higher publicly  available  estimated earnings growth rates for the COS Selected
Companies as compared with the growth rate  estimated by COS management for COS,
(ii) the  substantially  smaller  size of COS as  compared  to the COS  Selected
Companies  and (iii) the  diversification  of the COS  Selected  Companies  into
businesses with higher margins,  the application of a discount  estimated at 60%
to the foregoing  multiples  would be necessary to render the foregoing range of
LTM EBITDA meaningful for comparative purposes.  This adjustment yielded a range
of adjusted LTM EBITDA of 4.9 x to 5.5x, which resulted in an implied  valuation
range of $24.1  million to $26.9  million.  After giving effect to the potential
synergies  that may result from the  Transaction,  as well as to COS'  available
cash,  outstanding debt and off-balance  sheet  liabilities,  MLBAS estimated an
indicated range of implied values based on adjusted LTM EBITDA  multiples of the
COS Selected Companies of $26.9 million to $30.0 million.


                                       13

<PAGE>



         MLBAS has been  retained by the Board as an  independent  contractor to
express an opinion to the Board with respect to the Transaction and will receive
a fee for its  services.  MLBAS,  among other things,  regularly  engages in the
valuation  of  business  and   securities   in   connection   with  mergers  and
acquisitions.  In addition,  in the ordinary course of its securities  business,
affiliates  of MLBAS may actively  trade debt and/or  equity  securities  of the
Company  for its own  account  and the  accounts  of its  customers,  and MLBAS,
therefore,  may  from  time  to  time  hold a long  or  short  position  in such
securities.

         The  Company  and MLBAS  have  entered  into a letter  agreement  dated
February 28, 1997 relating to the services to be provided by MLBAS in connection
with the  Transaction.  The Company has paid MLBAS a cash fee of $75,000 and has
agreed to pay MLBAS an additional  cash fee of $75,000 payable at the time MLBAS
delivered  its  opinion.  In such  letter,  the Company also agreed to reimburse
MLBAS for its reasonable  out-of-pocket expenses incurred in connection with its
advisory work,  including the  reasonable  fees and  disbursements  of its legal
counsel,  and to indemnify  MLBAS  against  certain  liabilities  relating to or
arising out of the Transaction,  including  liabilities  which might arise under
the federal securities laws.

         In  choosing   MLBAS  to  render   services  in  connection   with  the
Transaction,   the  Company  contacted  several  investment  banking  firms  and
discussed with them their relevant experience, their ability to perform the such
services within the required time frame and the fee they would charge.  Based on
the foregoing,  the Company decided that MLBAS was the best candidate to provide
the required fairness opinion.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS  BELIEVES THAT THE REDEMPTION  TRANSACTION IS FAIR TO AND
IN THE BEST  INTEREST OF THE  COMPANY.  THE BOARD OF DIRECTORS  HAS  UNANIMOUSLY
APPROVED THE REDEMPTION TRANSACTION AND RECOMMENDS THAT YOU VOTE FOR APPROVAL OF
THE REDEMPTION TRANSACTION.

Principal Terms of the Transaction

         The terms of the Transaction are set forth in the Redemption Agreement.
The principal terms of the Transaction are summarized below.

         Recapitalization.  The entire  outstanding  equity  interest  of COS is
represented by 1,200 shares of a single class of common stock,  two-thirds  (800
shares) of which are held by Cerberonics and one-third (400 shares) of which are
held by Mr.  Manoogian.  Prior to  Closing,  COS will amend its  certificate  of
incorporation  to  authorize  the  issuance  of three  classes of common  stock,
Classes A, B and C. The  Redemption  Agreement  then provides that each share of
COS' existing  common stock will be exchanged for .61875,  .37125 and .01 shares
of the new Class A, B and C common stock, respectively (the "Recapitalization"),
after  which  Cerberonics  will  hold  two-thirds  and Mr.  Manoogian  will hold
one-third of each of COS' three classes of stock, respectively.

         Financing.  The Redemption  Agreement provides that COS will enter into
commercially  reasonable credit facilities to be arranged by GTCR to provide for
up to approximately $24 million in loans in connection with the Transaction (the
"Financing").  The  arrangement of such financing is not a condition to Closing.
If the  Financing is not arranged  prior to Closing and all other  conditions to
Closing are met, the  Redemption  Agreement  provides that the Investors will be
responsible for funding on commercially  reasonable  terms the sums necessary to
consummate the Transaction.

         Redemption.   At  Closing,  and  after  the  Recapitalization  and  the
Financing (or alternatively, a financing by the Investors), COS will redeem (the
"Redemption") all the shares of COS Class A (495),  Class B (297) and Class C(8)
common  stock held by  Cerberonics  at a price of $23,750  per share for a total
redemption price of $19 million (the "Redemption  Price"). The Redemption Price,
net of certain  holdbacks and adjustments as discussed  below,  shall be paid to
Cerberonics  by  wire  transfer  or  cashier's  check  at  Closing.   After  the
Redemption,  neither  Cerberonics  nor the Company will hold any interest in the
capital stock of COS.

                                       14

<PAGE>



         The $19 million Redemption Price includes the Company's $18 million pro
rata share of the $27  million  value of COS  negotiated  by the  parties to the
Redemption  Agreement,  plus a $1  million  control  premium  for the  Company's
two-thirds  controlling interest.  Such amounts were negotiated exclusive of the
Company's pro rata interest in the  approximately $5 million  distribution to be
made by COS prior to the Redemption.

         Investment.  Contemporaneous  with the Redemption,  the Investors shall
purchase  from COS 49.5  shares  and .5 shares of COS Class A and Class C common
stock, respectively,  at a price of $20,000 per share for a total purchase price
of $1 million (the "Investment").

         Stock Purchase. Contemporaneous with the Redemption and the Investment,
the Investors shall purchase (the "Stock Purchase") from Mr. Manoogian 247.5 and
2.5 shares of COS Class A and Class C common stock, respectively,  at a price of
$20,000 per share for a total purchase price of $5 million (the "Stock  Purchase
Price").  The Stock Purchase Price, net of certain  holdbacks and adjustments as
discussed  below,  shall be paid to Mr.  Manoogian by wire transfer or cashier's
check at Closing. After the Stock Purchase, Mr. Manoogian will hold 148.5 shares
(100%) of the COS Class B common stock  outstanding  and 1.5 shares  (33.33%) of
the COS Class C common  stock  outstanding,  while the  Investors  will hold 297
shares  (100%)  of the COS  Class A  common  stock  outstanding  and 3.0  shares
(66.67%) of the COS Class C common stock outstanding.

         The Stock  Purchase  Price  represents  that portion (5/8) of the value
ascribed to Mr. Manoogian's  one-third interest in COS that the Investors are to
acquire.  The value ascribed to Mr.  Manoogian's  interest in COS is $8 million,
which equals one-third of COS' negotiated $27 million value,  less the Company's
$1  million  control  premium.  The  Investors  are to  acquire  250 of the  400
post-Recapitalization  shares of COS Class A, B and C common stock to be held by
Mr. Manoogian, for which they are to pay $5 million (250/400 x $8 million). Such
amounts were negotiated exclusive of Mr. Manoogian's pro rata interest in the $5
million distribution to be made by COS prior to the Redemption.

         Escrow Arrangements.  The Redemption Agreement requires Cerberonics and
Mr.  Manoogian to place a total of $1.5 million in escrow (the "Escrow  Sum") at
Closing  to cover  certain  indemnity  obligations  that  may  arise  under  the
Redemption  Agreement  (the  "Escrow  Arrangement").  The  Escrow  Sum  is to be
comprised of $1,055,556 from Cerberonics, which amount will be deducted from the
Redemption Price otherwise payable to Cerberonics;  $277,778 from Mr. Manoogian,
which amount will be deducted from the Stock Purchase Price otherwise payable to
Mr.  Manoogian;  and  $166,666,  which  amount Mr.  Manoogian  shall  satisfy by
delivering  8.33 shares of COS Class B common stock to the escrow agent.  Claims
arising  from  indemnity  obligations  exclusive  to either  Cerberonics  or Mr.
Manoogian  shall be satisfied from that portion of the Escrow Sum contributed by
the respective party whose  obligation  gives rise to the claim.  Claims arising
from mutual indemnity obligations shall be allocated 19/27ths to Cerberonics and
8/27ths to Mr. Manoogian and satisfied from the respective portion of the Escrow
Sum  contributed by each.  Amounts shall be paid out of the Escrow Sum to either
COS or the Investors,  depending on which party suffers the economic loss giving
rise to the respective indemnity claim. The balance of the portion of the Escrow
Sum contributed by Cerberonics and Mr.  Manoogian that is not paid or claimed in
satisfaction  of indemnity  obligations  within 365 days after  Closing shall be
returned  to  Cerberonics  or  Mr.  Manoogian,  respectively.  A  more  complete
description  of the escrow  arrangements  can be found in the copy of the Escrow
Agreement included as Exhibit B to this Proxy Statement.


         Redemption Price and Stock Purchase Price  Adjustments.  The Redemption
Agreement  provides that the Redemption  Price to be paid  Cerberonics  shall be
reduced by 19/27ths and the Stock Purchase Price to be paid Mr.  Manoogian shall
be reduced by 8/27ths of the amount of certain indebtedness of COS to be paid at
Closing ("Paid  Indebtedness") and certain working capital  deficiencies of COS.
As of the date of the  Redemption  Agreement,  March  7,  1997,  the  Redemption
Agreement anticipates that there will be no Paid Indebtedness.

         The Redemption  Agreement  provides that a preliminary  working capital
deficiency  adjustment  ("Preliminary  Adjustment")  shall be made at Closing if
COS' estimated working capital at Closing as reflected

                                       15

<PAGE>



on a preliminary  closing balance sheet to be delivered within 3 to 7 days prior
to  Closing  ("Preliminary  Working  Capital")  is less than the  amount of COS'
month-end  average working capital for the six full calendar months prior to the
month in which the Closing occurs,  less $50,000 (the "Six Month Average").  The
Six Month  Average  shall be  calculated  assuming  that the cash  component  of
working  capital at the end of each month is the lesser of COS'  actual  cash or
$800,000.

         The Redemption  Agreement further provides for an audit, within 90 days
of  Closing,  of  the  preliminary  closing  balance  sheet  used  to  calculate
Preliminary  Working  Capital.  If  such  audit  results  in a  working  capital
determination  ("Audited Working Capital") lower than both the Six Month Average
and Preliminary Working Capital, the Redemption and Stock Purchase Prices are to
be further  reduced  (allocated  19/27ths  and  8/27ths to  Cerberonics  and Mr.
Manoogian, respectively) by the lesser of the difference between Audited Working
Capital and the Six Month  Average or the  difference  between  Audited  Working
Capital and  Preliminary  Working  Capital.  If Audited  Working Capital exceeds
Preliminary Working Capital,  the Redemption and Stock Purchase Prices are to be
increased  (allocated  19/27ths and 8/27ths to  Cerberonics  and Mr.  Manoogian,
respectively)  by the lesser of the difference  between  Audited Working Capital
and Preliminary  Working Capital or the difference between the Six Month Average
and  Preliminary  Working  Capital.  Any adjustments to the Redemption and Stock
Purchase  Prices  based on the audit  (either  up or down) are to be paid by the
respective parties in immediately  available funds within 10 days of delivery of
the audited balance sheet.

         The Redemption  Agreement also provides that if the Transaction  closes
after July 4, 1997 and COS  retains  its cash flow after such date,  Cerberonics
and Mr.  Manoogian  shall  earn  interest,  beginning  July 5,  1997,  on  their
respective  Redemption  Price and Stock Purchase Price,  calculated at the prime
rate announced by The Chase Manhattan Bank on July 5, 1997.

         Representations  and  Warranties.  The  Redemption  Agreement  contains
various  representations and warranties of the parties thereto.  With respect to

vote upon the Transaction.  The Redemption  Agreement  further provides that the
Board shall recommend approval by the Company's  stockholders of the Transaction
and take all lawful action to solicit such approval.  The  Redemption  Agreement
contemplates that the Board shall seek and condition approval of the Transaction
on approval by a majority of the votes cast by the Non-Erikson Stockholders, and
that such a majority vote, coupled with the vote of the Eriksons pursuant to the
Voting Agreement, shall be sufficient to approve the Transaction.

         The Redemption  Agreement also provides that COS will not, and that the

         In addition,  the Redemption Agreement provides that from March 7, 1997

status of any actions relating thereto.

         Conditions to Closing.  Closing of the Transaction is subject to, among
other  conditions,  the vote in favor of the  Transaction  of a majority  of the
votes  cast  by  the  Non-Erikson  Stockholders.  As of  the  record  date,  the
Non-Erikson  Stockholders held -----------  shares of outstanding  Common Stock,
entitling them to cast -----------  votes, and ----------- shares of outstanding
Class B Common Stock,  entitling them to cast -----------  votes, for a total of
votes eligible to be cast by the Non-Erikson Stockholders.

         In  addition,  the  Transaction  is subject to the vote in favor of the
Transaction of a majority of the votes  entitled to be cast by all  stockholders
of the Company.  With respect  thereto,  the Eriksons have entered into a voting
agreement  (See "Related  Agreements -- Erikson Voting  Agreement")  pursuant to
which  each  of  them  agrees,  so  long  as a  majority  of  votes  cast by the
Non-Erikson Stockholders are voted in favor of the Transaction, to vote in favor
of the Transaction  all of the shares of the Company's  Common Stock and Class B
Common Stock held by each of them, exclusive of 2,246 shares of Common Stock and
2,246 shares of Class B Common Stock held jointly by George Wm. Erikson with his
spouse. Pursuant to such voting

                                       17

agreement, in the event a majority of votes cast by the Non-Erikson Stockholders
are voted in favor of the Transaction, the Eriksons have agreed to cast at least
2,568,486 votes in favor of the Transaction,  which number of affirmative  votes
alone would satisfy  Section 271 of the Delaware  Corporation  Law requiring the
affirmative  vote of at least a majority  of all votes  entitled  to be cast for
approval of the Transaction.

         Indemnification.  The  Redemption  Agreement  sets forth the Company's,
Cerberonics',  and Mr.  Manoogian's  obligations  to indemnify the Investors and
their officers,  directors and affiliates from and against costs arising out of:
their  misrepresentation,  breach or default  of or under any of the  covenants,
agreements or other  provisions set forth in the  Redemption  Agreement or other
agreements  related  thereto;  claims or liability  arising out of litigation or
potential  litigation  for which COS should have but did not establish a reserve
within its  financial  statements;  and  tortious  acts or omissions of COS, the
Company,  Cerberonics  or Mr.  Manoogian  that  occurred  prior to Closing.  The
indemnification  obligations  are  generally  borne jointly and severally by the
Company and Mr.  Manoogian,  except with respect to  liability  assigned to each
based on, among other factors, the knowledge of the respective parties. There is
no  indemnification  obligation until the aggregate  indemnification  obligation
exceeds $50,000.  Thereafter,  except with respect to liability arising from the
breach of certain  representations  and warranties,  there is liability only for
amounts in excess of $50,000 up to an amount equal to 10% of the total  combined
Redemption  and  Stock  Purchase  Prices  (i.e.  an  approximate  limit  of $2.4
million).  With respect to liability arising from the breach of  representations
and  warranties  relating  to (i) COS'  capitalization  and  rights of others to
acquire COS capital stock,  (ii) due authorization of shares to be issued to the
Investors  pursuant to the  Investment,  (iii) the  adequacy and accuracy of tax
returns and tax filings,  and (iv) the absence of liens or  encumbrances  on the
COS  capital  stock  to be  redeemed  from  Cerberonics  or  purchased  from Mr.
Manoogian,  the indemnify  obligation of the Company and Mr.  Manoogian shall be
unlimited.

         Break-Up  Fees. The  Redemption  Agreement  provides for the payment of
certain fees in the event the Redemption  Agreement is terminated  under certain
circumstances.  If the Investors  terminate the Redemption  Agreement other than
(i) upon mutual  consent of the  parties to the  Redemption  Agreement,  (ii) in
response  to  litigation,  pending  or  threatened,  restraining  or  seeking to
restrain  the  transactions  contemplated  by the  Redemption  Agreement,  (iii)
because certain  conditions to Closing were not satisfied,  (iv) upon withdrawal
by the Board of its approval of the Redemption  Agreement,  (v) upon issuance of
an unfavorable  fairness opinion from an investment banker, or (vi) rejection by
the Company's stockholders of the Transaction, or the Company's failure to close
the Transaction  after  satisfaction of the conditions  thereto,  the Redemption
Agreement provides for the payment by the Investors of $1 million to Cerberonics
and Mr.  Manoogian (to be allocated  19/27ths to Cerberonics  and 8/27ths to Mr.
Manoogian).  Similarly,  if the Company terminates the Redemption Agreement upon
entering into a definitive  agreement  with a third party for the sale of either
the assets or capital  stock of COS, or the Board  withdraws its approval of the
Redemption  Agreement,  the Redemption Agreement provides for the payment by the
Company of $1 million to the Investors.  The Redemption  Agreement also provides
that the Company  shall pay a fee of $250,000 to the  Investors if the Company's
stockholders fail to approve the Transaction, or if the Company does not proceed
with the Transaction because an investment banker issues an unfavorable fairness
opinion regarding the Redemption Agreement.  In such case, if the Company enters
into a definitive agreement with a third party for the sale of either the assets
or capital stock of COS within one year  thereafter,  the  Redemption  Agreement
provides  for the  payment  by the  Company  of an  additional  $750,000  to the
Investors.

         Related Agreements.

         Erikson Consulting and  Non-Competition  Agreement.  In connection with
the Transaction, the Redemption Agreement contemplates that each of the Eriksons
shall  enter  into  a  three-year   consulting  and  non-competition   agreement
("Consulting  Agreement")  with COS  effective  as of  Closing.  Pursuant to and
during  the  term  of  the  Consulting  Agreement,  the  Eriksons  shall  at all
reasonable  times be available to COS on a mutually  agreeable "as needed" basis
to serve as an advisor and  consultant to COS, its  management  and its Board of
Directors in connection  with the  operation of COS'  business.  The  Consulting
Agreement provides that each of the Eriksons shall be available to COS to render
such services at least one and up to three days each month,  which  services are
to be scheduled and performed in a manner that will not detract from their

                                       18

<PAGE>



performance as directors and officers of the Company.  The Consulting  Agreement
also  provides  that the Eriksons  will keep  confidential  certain  information
relating to COS and the  operation of its  business  which they may obtain while
rendering  services  pursuant to the  Consulting  Agreement.  In  addition,  the
Consulting  Agreement  provides that the Eriksons shall not,  during the term of
the  Consulting  Agreement  and for up to two  years  thereafter,  engage in any
manner (except  through  ownership of less than 5% of a publicly traded company)
in any business that competes with COS or solicit for  employment  elsewhere the
employees of COS.

         In return for the Eriksons'  non-disclosure and non-compete agreements,
the  Consulting  Agreement  provides  for the payment of $150,000 to each of the
Eriksons promptly after Closing.  In contemplation of the consulting services to
be rendered by the Eriksons,  the Consulting  Agreement provides for the payment
of  $150,000  to each  of the  Eriksons.  Unless  COS  and  the  Eriksons  agree
otherwise,  such amount is scheduled to be paid to each of the Eriksons in three
annual  $50,000  payments,  the first of which is due promptly after Closing and
the  remaining  two of which are due,  respectively,  on the  first  and  second
anniversaries  thereof,  if the Eriksons are  available and able to provide such
services.  The Consulting  Agreement  contemplates that late payments of amounts
due thereunder  shall bear interest at the rate of eight percent per annum until
paid. A copy of the Consulting  Agreement is included as Exhibit D to this Proxy
Statement.

         Erikson Voting  Agreement.  In connection with the condition to Closing
that a majority  of the votes  entitled  to be cast by all  stockholders  of the
Company be cast in favor of the  Transaction,  the Eriksons  have entered into a
voting agreement (the "Voting Agreement")  pursuant to which each of them agrees
to vote in favor of the  Transaction  all of the shares of the Company's  Common
Stock and Class B Common  Stock held by each of them,  exclusive of 2,246 shares
of Common  Stock and 2,246 shares of Class B Common Stock held jointly by George
Wm. Erikson with his spouse.  The Voting Agreement provides that such obligation
is contingent upon a majority of the votes cast by the Non-Erikson  Stockholders
being cast in favor of the Transaction.  Pursuant to the Voting  Agreement,  the
Eriksons have also granted to GTCR an irrevocable proxy to vote such shares with
respect to certain matters which may arise relating to, or which may impede, the
Transaction.

         The  Voting  Agreement  provides  that  to  the  extent  the  Company's
directors other than the Eriksons were permitted in the proper exercise of their
fiduciary  duties to commit  the  Company to  indemnify  the  Eriksons  in their
capacities as  stockholders,  the Company shall  indemnify and hold harmless the
Eriksons in their  capacities  as  stockholders  with  respect to the review and
negotiation of the Voting Agreement and, with certain exceptions and limitations
with respect to litigation by other  stockholders of the Company,  other parties
to the agreement and third parties.  In addition,  the Voting Agreement provides
that the  Eriksons  shall  indemnify  the  Company's  directors,  other than the
Eriksons,  to the extent that they are not otherwise  indemnified by the Company
or  under  policies  of  insurance  maintained  by the  Company,  against  costs
reasonably  incurred  by them  arising  from  the  Company's  entering  into the
agreement to indemnify the Eriksons  under the Voting  Agreement.  A copy of the
Voting Agreement is included as Exhibit C to this Proxy Statement.

         Manoogian Executive Agreement. In connection with the Transaction,  the
Redemption Agreement  contemplates that COS and Mr. Manoogian will enter into an
Executive Agreement (the "Executive  Agreement") pursuant to which Mr. Manoogian
will serve as the President of COS for an initial three year term. The Executive
Agreement renews automatically for additional  successive one year terms, at the
end of the  initial  three  year term and each  anniversary  thereafter,  unless
either COS or Mr.  Manoogian  terminates  the Executive  Agreement in writing at
least 30 days prior to the end of any such term.

         The  Executive  Agreement  provides  for Mr.  Manoogian  to  receive an
initial  annual base salary of  $200,000,  subject to periodic  increases at the
discretion  of the COS Board of Directors  (the "COS Board").  In addition,  the
Executive  Agreement  provides  that Mr.  Manoogian  may earn,  beginning in the
fiscal year ending June 30, 1998,  an annual bonus of up to one-half of his then
base annual salary, if COS meets certain yearly business targets  established by
the COS  Board.  Mr.  Manoogian  is also  entitled,  pursuant  to the  Executive
Agreement,  to certain other fringe benefits  approved by the COS Board and made
available to other COS senior executives.  In addition,  the Executive Agreement
sets forth certain non-competition and confidentiality

                                       19

<PAGE>



agreements  of Mr.  Manoogian  relating to his  employment by COS. A copy of the
Executive Agreement is included as Exhibit E to this Proxy Statement.

         Other Related Agreements.  The Redemption  Agreement  contemplates that
the  parties to the  Transaction  and  others  will  enter  into  various  other
agreements relating thereto.  Such agreements  include,  but are not limited to:
(i) an agreement among the Investors and Mr.  Manoogian as  post-Redemption  COS
stockholders  with respect to  establishing  COS' board of  directors,  assuring
continuity  of COS'  management  and  ownership,  limiting  stock  transfers and
providing for supermajority  voting for certain matters; and (ii) a registration
agreement between COS and the Investors granting investors certain  registration
rights relating to the COS stock they are to receive.

Interests of Certain Persons in the Transaction

         Other than as described herein, no director or executive officer of the
Company, and no associate of such persons, has any substantial interest,  direct
or indirect,  in the  Transaction,  other than in the interest  arising from the
ownership of the Company's  Common Stock and Class B Common Stock, in which case
the director or officer receives no extra or special benefit not shared on a pro
rata basis by all other holders of such stock.

         The Redemption Agreement contemplates that effective as of Closing each
of the Eriksons  shall enter into a three-year  consulting  and  non-competition
agreement  with COS  pursuant  to which each is  scheduled  to receive  $200,000
promptly  after  Closing,  $50,000 one year after  Closing and $50,000 two years
after Closing.  See "Erikson  Consulting and  Non-Competition  Agreement"  under
"Related Agreements" above.

Federal Income Tax Consequences

         The  Transaction  will be a taxable  transaction  to the  Company.  The
Company will  recognize  gain measured by the  difference,  if any,  between the
amount realized from the Redemption and the Company's  adjusted tax basis in the
COS stock being redeemed.  The Transaction will not be a taxable  transaction to
the Company's stockholders.

Regulatory Requirements

         To the Company's  knowledge,  there are no federal or state  regulatory
requirements  which must be complied with,  nor are there any such  governmental
consents or approvals that must be obtained, in connection with the Transaction.

Accounting Treatment

         The Transaction, if approved by the stockholders, will be accounted for
as a  disposal  of a  segment  of a  business.  In  accordance  with  Accounting
Principles  Board  Opinion  No.  30,  "Reporting  the  Results of  Operations  -
Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary,
Unusual and  Infrequently  Occurring  Events and  Transactions"  ("APB 30"), the
results of  operations of COS will be removed from the  consolidated  results of
operations of the Company and shown separately as discontinued operations on the
Company's  Statement of Earnings as of the measurement  date,  which will be the
date of the Meeting.  The expected gain from the Transaction  will be recognized
when  realized  on the date of the  Closing.  In  accordance  with  APB 30,  the
recognized  gain will include any income or loss of generated by COS between the
measurement date and Closing.


                                 USE OF PROCEEDS

         The   Company   anticipates   receiving    approximately    $22,000,000
($19,000,000  purchase  price  plus  two-thirds  of  an  approximate  $5,000,000
pre-Closing dividend) as a consequence of the Transaction, before

                                       20

<PAGE>



transaction expenses. Promplty after Closing, the Company intends to declare and
distribute  a dividend  of $1.50 per share to the  holders  of Common  Stock and
Class B Common Stock, as of a record date proximate to Closing.  Based on shares
outstanding  as of the Record Date for the Meeting,  the Company  estimates such
dividend to total  $2,211,000.  The balance of the proceeds from the Transaction
will be used for general  corporate  purposes and for potential  acquisitions of
businesses,   technologies   or   products.   The  Company   currently   has  no
understanding,  commitment or agreement  with respect to any such  acquisitions.
Pending  such  uses,  the  Company  intends  to  invest  the  proceeds  from the
Transaction in short term, investment grade, interest bearing securities.

                           INVESTMENT, REDEMPTION AND
                            STOCK PURCHASE AGREEMENT


                  THIS INVESTMENT, REDEMPTION AND STOCK PURCHASE AGREEMENT (this
"Agreement")  is entered into as of March 7, 1997, by and among  GOLDER,  THOMA,
CRESSEY,  RAUNER FUND IV, L.P., a Delaware limited  partnership  ("GTCR IV"), on
behalf of itself and certain other  investors  who may execute a joinder  hereto
and shall be  listed  on  Schedule  1 of this  Agreement  (GTCR IV and the other
signatory  investors  shall be referred to herein  individually as an "Investor"
and  collectively as the  "Investors"),  CAPITOL OFFICE  SOLUTIONS,  INC. (f/k/a
Capitol Copy Products,  Inc.), a Delaware  corporation (the "Company"),  CERBCO,
INC.,  a  Delaware  corporation  ("Cerbco"),   CERBERONICS,   INC.,  a  Delaware
corporation   and  a   wholly-owned   subsidiary   of   Cerbco   ("Cerberonics")
(collectively, Cerbco and Cerberonics are referred to herein as the "Cerberonics
Parties"),  and ARMEN  MANOOGIAN  ("Manoogian";  collectively,  the  Cerberonics
Parties and Manoogian are sometimes referred to herein as the "Stockholders" and
individually as a "Stockholder").


                                    Recitals

     Pursuant to this  Agreement,  the  Company,  which is engaged in the office
equipment dealer and service industry in the Washington,  D.C. metropolitan area
(the  "Business"),   will  be  recapitalized  in  a  series  of  contemporaneous
transactions. Due to the complexity of these transactions,  they will be briefly
described in the following recitals:

a.   THE CURRENT CAPITALIZATION OF THE COMPANY

     On the date of this  Agreement,  the Company's  capitalization  consists of
40,000 shares of Common Stock, $.10 par value, of which no shares are issued and
outstanding, and 10,000 shares of Class B Common Stock, $.10 par value, of which
1,200 shares are issued and  outstanding.  No preferred  stock is  authorized or
outstanding.  Cerberonics  owns 800  shares of the Class B Common  Stock  (i.e.,
two-thirds  of the  outstanding  equity) and  Manoogian  owns the  remaining 400
shares of the Class B Common Stock (i.e.,  one-third of the outstanding equity).
A chart showing the details of the Company's current capitalization is set forth
in Part 1 of Schedule 2 attached hereto.

b.   THE RECAPITALIZATION

     Prior to the closing of the transactions  described in Recitals C through F
below (collectively,  the "Transactions"),  the Company will recapitalize itself
(the  "Recapitalization"),  by amending  its  Certificate  of  Incorporation  to
authorize  three classes of common stock,  Class A Common Stock,  $.01 par value
(the  "Class A  Common"),  Class B Common  Stock,  $.01 par value (the  "Class B
Common"),  and Class C Common  Stock,  $.01 par  value  (the  "Class C  Common,"
together  with the Class A Common and the Class B Common,  the "Common  Stock").
Pursuant to the  Recapitalization,  each share of the Company's currently issued
and  outstanding  Class B Common  Stock will be exchanged  for .61875  shares of
Class A  Common,  .37125  shares  of Class B Common  and .01  shares  of Class C
Common. A chart showing the details of the Recapitalization is set forth in Part
2 of Schedule 2 attached hereto.

c.   THE FINANCING

     It is  anticipated  that the Company will enter into a credit  agreement or
agreements with a financial  institution or institutions (the "Financing") to be
arranged by GTCR IV (the "Credit  Facilities"),  which Credit  Facilities  shall
provide for a loan or loans to the Company on commercially reasonable terms in




                                        1

<PAGE>



connection with the  Transactions in the principal amount of up to approximately
$24,000,000 (the "Loan Proceeds"). The closing of the Credit Facilities is not a
condition  precedent to the closing of the  Transactions,  and if for any reason
the  Financing  is not  fully  consummated,  such  that  some or all of the Loan
Proceeds  are not  received by the  Company,  but all of the  remaining  closing
conditions  to  this  Agreement  are  satisfied,  then  the  Investors  will  be
responsible for funding on commercially  reasonable  terms the sums necessary to
consummate  the  Transactions  (any such  other  funds,  together  with any Loan
Proceeds as  necessary  to  consummate  the  Transactions,  shall be referred to
herein as the "Financing Proceeds").

d.   THE REDEMPTION

     Following the Recapitalization and, if it occurs, the closing of the Credit
Facilities,  and subject to the terms and conditions of this  Agreement,  all of
the shares of Class A Common,  Class B Common and Class C Common of the  Company
held by Cerberonics (the  "Cerberonics  Shares") will be redeemed by the Company
for a purchase  price of $23,750 per share and an  aggregate  purchase  price of
$19,000,000  subject to adjustment and escrow holdbacks as provided herein) (the
"Redemption").

e.   THE INVESTMENT

     Contemporaneously  with  the  Redemption,  and  subject  to the  terms  and
conditions of this Agreement,  the Investors will purchase from the Company 49.5
shares of Class A Common and .5 shares of Class C Common for a purchase price of
$20,000  per  share  and  an  aggregate   purchase  price  of  $1,000,000   (the
"Investment").

f.   THE STOCK PURCHASE

     Contemporaneously  with the Redemption and the  Investment,  and subject to
the terms and  conditions of this  Agreement,  the Investors  will purchase from
Manoogian  all 247.5 shares of Class A Common held by him and 62.5% of the Class
C Common (2.5 shares) held by him for a purchase  price of $20,000 per share and
an aggregate  purchase  price of $5,000,000  (subject to  adjustment  and escrow
holdbacks as provided  herein) (the "Stock  Purchase").  In connection  with the
Transactions,  Manoogian,  the Investors and the Company will enter into various
stockholder   agreements,   registration   rights   agreements   and  employment
agreements,  all  as  provided  herein.  A  chart  showing  the  effect  of  the
Transactions on the Company's  capitalization is set forth in Part 6 of Schedule
2 attached hereto.

g.   SUMMARY OF THE TRANSACTIONS

     In sum, in the context of the  Transactions  the Company is being valued at
$27,000,000.  Cerberonics is receiving  $19,000,000 for redeeming its two-thirds
interest,  which is equal to two-thirds of $27,000,000 plus a $1,000,000 control
premium.  Manoogian's  one-third interest is therefore valued at $8,000,000.  He
will receive  $5,000,000 in conjunction  with the  Transactions for a portion of
his  interest in the  Company  and will end up with a one-third  interest in the
newly leveraged Company,  with the remaining  two-thirds  interest being held by
the  Investors.  The foregoing  valuation and payments are subject to adjustment
and  holdbacks as provided  herein.  In addition to the  foregoing,  immediately
prior to the Closing,  the Company will  distribute to Cerberonics and Manoogian
(in proportion to their respective two-thirds/one-third interest in the Company)
all but approximately $800,000 of the Company's cash.

          "Tax Return" means any return, report or similar statement required to
     be filed with  respect to any Taxes  (including  any  attached  schedules),
     including,  without limitation,  any information return,  claim for refund,
     amended return and declaration of estimated Tax.

          "Transaction Date" has the meaning specified in Section 2.8(c).

          "Working  Capital"  shall mean the  difference  between the  Company's
     current assets and its current  liabilities as such items are calculated in
     accordance with GAAP, consistent with the Company's past practices.


                                   ARTICLE II
                      THE REDEMPTION, FINANCING, INVESTMENT
                               AND STOCK PURCHASE

2.1  Recapitalization.  Prior to the Closing  Date,  the Company shall amend its
     Certificate of Incorporation to authorize the issuance of the three classes
     of the Common Stock (i.e.,  Class A Common Stock,  Class B Common Stock and
     Class C Common Stock) each having the rights and  preferences  set forth in
     the   Amendment  to  the  Company's   Certificate   of   Incorporation   in
     substantially  the form of  Exhibit F  attached  hereto and as set forth in
     more  detail  in the chart in Part 2 of  Schedule  2, and as  necessary  to
     effect the Transactions.

2.2  The  Financing.  On the Closing Date,  assuming such  facilities  have been
     arranged,  the Company shall  consummate the Financing by entering into the
     Credit Facilities.  The closing of the Credit Facilities is not a condition
     precedent  to the  closing of the  Transactions,  and if for any reason the
     Company is unable to borrow a sufficient  amount of Loan Proceeds,  but all
     of the other  conditions  precedent to the consummation of the Transactions
     have been  satisfied,  then the  Investors  shall be required to provide or
     otherwise  arrange   sufficient   Financing   Proceeds  to  consummate  the
     Transactions.

2.3  The Redemption; Redemption Price. On the Closing Date, subject to the terms
     and  conditions  set  forth  herein,   the  Company  shall  consummate  the
     Redemption by redeeming all of the Cerberonics Shares (i.e., the 495 shares
     of Class A Common,  297  shares  of Class B Common  and 8 shares of Class C
     Common) held by the Cerberonics Parties following the Recapitalization (see
     Part 2 of Schedule 2).  Subject to the terms of Sections 2.7, 2.8 and 2.11,
     which  provisions  require certain  holdbacks and adjustments  prior to the
     distribution of such price to Cerberonics,  the Cerberonics Shares shall be
     redeemed at a price of $23,750 per share, for an aggregate gross redemption
     price of $19,000,000 (the "Redemption Price").

2.4  The Investment. On the Closing Date, contemporaneously with consummation of
     the  Redemption  and subject to the terms and  conditions set forth herein,
     the  Company and the  Investors  shall  consummate  the  Investment  by the
     Investors  purchasing from the Company, and the Company issuing and selling
     to the  Investors,  49.5  shares of Class A Common and .5 shares of Class C
     Common at a price of $20,000 per share, for an aggregate  purchase price of
     $1,000,000 (the "Investment Price") (see Part 4 of Schedule 2).

2.5  The  Stock  Purchase.  On the  Closing  Date,  contemporaneously  with  the
     consummation  of the Redemption and the Investment and subject to the terms
     and  conditions  set  forth  herein,  the  Investors  and  Manoogian  shall
     consummate  the Stock Purchase by Manoogian  selling to the Investors,  and
     the Investors purchasing from Manoogian, 247.5 shares of Class A Common and
     2.5  shares  of Class C Common  (the  "Manoogian  Shares")  (see  Part 5 of
     Schedule  2).  Subject to the terms of Sections  2.7,  2.8 and 2.11,  which
     provisions   require  certain   holdbacks  and  adjustments  prior  to  the
     distribution of the stock purchase price to Manoogian, the Manoogian Shares
     shall be purchased at a price of $20,000 per share,  for an aggregate gross
     purchase price of $5,000,000 (the "Stock Purchase Price").

2.6  Allocation Among the Investors. GTCR IV is the sole Investor as of the date
     that this Agreement is executed;  provided,  however, that on or before ten
     (10) days prior to the Closing  Date,  GTCR IV will present the Company and
     the Stockholders  with an updated Schedule 1 (the "Schedule of Investors"),
     and each  additional  Investor shown thereon shall execute a counterpart of
     this  Agreement on or prior to the Closing Date in accordance  with Section
     10.15.  Allocation  as among the  Investors of the Shares  purchased by the
     Investors pursuant to the Investment and the Stock Purchase shall be as set
     forth on the Schedule of Investors,  and the overall  capitalization of the
     Company following the consummation of all of the Transactions,  shall be as
     set forth in Part 6 of Schedule 2.

2.7  Escrow Arrangements. Pursuant to the Escrow Agreement (in substantially the
     form of Exhibit A) to be entered into among the Stockholders,  the Company,
     the  Investors  and the Escrow Agent,  the  Stockholders  shall cause to be
     delivered to the Escrow Agent at Closing $1,500,000,  which amount shall be
     allocated as follows: (i) in respect of the Cerberonics Parties, $1,055,556
     (19/27 x $1,500,000)  shall be deducted from the Redemption Price; and (ii)
     in respect of Manoogian,  (A) $277,778 (= 8/27 x $1,500,000 x 5/8) shall be
     deducted from the Stock Purchase  Price,  and (B) Manoogian will deliver to
     the Escrow Agent  pursuant to the Escrow  Agreement  8.33 shares of Class B
     Common Stock (=(8/27 x $1,500,000 x 3/8) / $20,000).  (The cash portions of
     such escrowed amounts, together with interest accrued thereon and the Class
     B Common Stock  escrowed by  Manoogian  shall be referred to as the "Escrow
     Sum.")  The Escrow  Sum shall be held  pursuant  to the terms of the Escrow
     Agreement for payment of amounts,  if any, owing by the Stockholders to the
     Company or the Investors in accordance with Article VIII below.  The Escrow
     Agreement  shall  provide for the proper  allocation of claims made against
     the  Escrow  Sum by the  Investors  as among the  Cerberonics  Parties  and
     Manoogian, as well as the priority as between the cash and stock portion of
     the  Escrow  Sum  contributed  by  Manoogian.   Where  the  indemnification
     obligations are mutual (as between the Cerberonics  Parties and Manoogian),
     the proper  allocation of  responsibility  under such  provisions  shall be
     19/27ths,  the  Cerberonics  Parties  and  8/27ths,  Manoogian.  Where  the
     indemnification  obligations  are separate  (e.g.,  where  Manoogian has an
     indemnification  obligation  under  this  Agreement,  but  the  Cerberonics
     Parties do not), the




                                        8

<PAGE>



Investors or the Company shall  proceed  separately  under the Escrow  Agreement
against the  Stockholder(s)  which has the obligation to indemnify the Investors
or the Company . Where the  indemnification  is a result of a claim involving an
economic loss to or of the Company,  the relevant  Escrow Sum shall be delivered
to the Company, and where the claim involves a direct (as opposed to derivative)
economic loss to the  Investors,  such funds shall be delivered to the Investors
on a pro-rata  basis.  At the  conclusion  of the period ending on the 365th day
after the  Closing  Date (such  period  being  referred to herein as the "Escrow
Period"),  such portion of the Escrow Sum not theretofore  claimed by or paid to
the Company or the Investors,  as the case may be, in accordance  with the terms
of  the  Escrow   Agreement  and  this  Agreement  shall  be  disbursed  to  the
Stockholders as provided in the Escrow Agreement. The Stockholders,  the Company
and the Investors agree that each will execute and deliver such  instruments and
documents  as are  reasonably  furnished  by any  other  party  to  enable  such
furnishing  party to  receive  those  portions  of the  Escrow  Sum to which the
furnishing  party is entitled under the  provisions of the Escrow  Agreement and
this Agreement.

2.8  Redemption Price and Stock Purchase Price Adjustments.

               (a) Funded Indebtedness Adjustment. The Redemption Price shall be
          reduced by an amount equal to 19/27ths,  and the Stock  Purchase Price
          shall be reduced by an amount equal to 8/27ths, of the total amount of
          any Funded  Indebtedness  paid at the Closing to satisfy the Company's
          Funded Indebtedness as at the Closing Date;  provided,  however,  that
          the term "Funded  Indebtedness"  shall not include  borrowings  of the
          Company under the Credit  Facilities  (if any),  it being  anticipated
          that the Financing Proceeds will be used at the Closing, in accordance
          with the terms of Section  7.1(e)  hereof,  to satisfy,  discharge and
          refinance the Company's  Funded  Indebtedness  (if any) existing as at
          the Closing Date.

               (b) Working  Capital  Adjustment.  The  Redemption  Price will be
          further reduced by an amount equal to 19/27ths, and the Stock Purchase
          Price shall be further  reduced by an amount equal to 8/27ths,  of the
          total amount, if any, by which the Working Capital as reflected on the
          Preliminary  Closing  Balance  Sheet is less than that amount which is
          $50,000 less than the average of the working  capital  balances of the
          Company at the end of each of the six full  calendar  months  prior to
          the month in which the Closing  occurs,  assuming for purposes of each
          such average,  that the cash component of Working Capital shall be the
          actual cash for each such month or  $800,000,  whichever is the lesser
          amount.

               (c) Adjustment if Closing Occurs After the  Transaction  Date. In
          the event the Closing does not occur prior to a date which is 120 days
          after the date of this Agreement  (the  "Transaction  Date"),  and the
          Company's  Cash Flow (as defined in Section  2.14)  subsequent  to the
          Transaction  Date shall be retained by the Company pursuant to Section
          2.14,  then the  Redemption  Price and the Stock  Purchase Price shall
          each be adjusted  upward in accordance  with the last sentence of this
          Section  2.8(c),  on a  dollar-for  dollar  basis,  by the  amount  of
          interest earned on the Net Redemption Price and the Net Stock Purchase
          Price during the period  commencing on the Transaction Date and ending
          on the Closing  Date,  calculated  at the prime rate of  interest  per
          annum as at the  Transaction  Date  publicly  announced  by The  Chase
          Manhattan Bank. Any adjustment made under this Section 2.8(c) shall be
          allocated  19/27ths to the  Redemption  Price and 8/27ths to the Stock
          Purchase Price.

               (d)  Allocation.  Any  reduction  to  the  Stock  Purchase  Price
          pursuant  to  paragraphs  (a) or (b) of  this  Section  2.8  shall  be
          allocated pro-rata among the Investors.

2.9  Payment  of  Net   Redemption   Price  and  Net  Stock  Purchase  Price  to
     Stockholders.  On the Closing  Date,  following  the  establishment  of the
     escrow under Section 2.7 and the Redemption  Price and Stock Purchase Price
     adjustments required under Section 2.8, the remaining Redemption Price (the
     "Net  Redemption  Price")  shall be paid to  Cerberonics  and the remaining
     Stock  Purchase  Price (the "Net Stock  Purchase  Price")  shall be paid to
     Manoogian. The Net Redemption Price and the




                                        9

<PAGE>



     Net Stock  Purchase  Price  shall each be paid in cash by wire  transfer of
     funds or by cashier's  checks to the accounts of Cerberonics and Manoogian,
     as the same are specified in Schedule 2.9.

2.10 Closing Audit.  Within ninety (90) days  following the Closing Date,  there
     shall be delivered to the Investors,  the Company and the  Stockholders  an
     audit,  prepared by Ernst & Young in  accordance  with  generally  accepted
     auditing  standards (and  consistent with the Company's  audited  financial
     statements for the 1994,  1995 and 1996 fiscal years),  of the  Preliminary
     Closing  Balance  Sheet of the  Company at and as of the Closing  Date.  In
     connection with such audit, the Preliminary  Closing Balance Sheet shall be
     adjusted in accordance with GAAP (as so audited and adjusted,  the "Audited
     and Adjusted Closing Balance Sheet").  The cost of the Audited and Adjusted
     Closing  Balance  Sheet shall be paid by the  Company.  In the event that a
     Stockholder  disputes  any  item(s) on the  Audited  and  Adjusted  Closing
     Balance Sheet within ten days after the Stockholders'  receipt thereof, the
     disputing   Stockholder  or   Stockholders   shall  select  and  retain  an
     independent  "Big Six" accounting firm (the  "Independent  Accountants") to
     review the  disputed  item(s) on the Audited and Adjusted  Closing  Balance
     Sheet. The final  determination of such disputed item(s) by the Independent
     Accountants  shall be reflected on the Audited and Adjusted Closing Balance
     Sheet. The cost of retaining the Independent  Accountants shall be borne by
     the Stockholders; provided, however, that the Investors shall reimburse the
     Stockholders  for 100% of the cost of the  Independent  Accountants  in the
     event that such review  results in an increase of more than  $25,000 in the
     Company's  Working Capital as reflected on the Audited and Adjusted Closing
     Balance Sheet prepared by Ernst & Young.

2.11 Post-Closing  Redemption Price and Stock Purchase Price Adjustment.  In the
     event that the Working  Capital as  reflected  on the Audited and  Adjusted
     Closing  Balance  Sheet is $50,000  less than the  average  of the  working
     capital balances on the Company's monthly financial  statements for the six
     full  calendar  months  prior  to the  month in which  the  Closing  occurs
     (assuming  for the  purposes of such  average  that the cash  component  of
     Working  Capital  shall be the  actual  cash for such  period or  $800,000,
     whichever is the lesser  amount),  then the Redemption  Price and the Stock
     Purchase Price will each be adjusted  downward in accordance  with the last
     sentence of this Section 2.11, on a dollar-for-dollar basis, to reflect the
     lesser  of (i) the  decrease,  if any,  in the  total  Working  Capital  as
     reflected on the Audited and Adjusted Closing Balance Sheet from the amount
     of Working Capital  reflected on the  Preliminary  Closing Balance Sheet or
     (ii) the amount,  if added to the Working Capital  reflected on the Audited
     and Adjusted Closing Balance Sheet, which would sum to that number which is
     $50,000  less than the  average  of the  working  capital  balances  on the
     Company's  monthly  financial  statements for the six full calendar  months
     prior to the month in which the Closing occurs.  Conversely, the Redemption
     Price and the Stock  Purchase  Price will be adjusted  upward in accordance
     with the last sentence of this Section 2.11, on a dollar-for  dollar basis,
     to reflect the increase,  if any, in the total Working Capital as reflected
     on the  Audited  and  Adjusted  Closing  Balance  Sheet  from the amount of
     Working  Capital  reflected  on  the  Preliminary  Closing  Balance  Sheet;
     provided, however, that in no event shall such upward adjustment exceed the
     total  amount  of any  adjustment  to the  Redemption  Price  and the Stock
     Purchase  Price made  pursuant to Section  2.8(b) above.  The  post-closing
     adjustment to the Redemption  Price and the Stock Purchase  Price,  if any,
     shall be paid by the  Stockholders  to the Company or by the Company to the
     Stockholders, as the case may be, in immediately available funds within ten
     (10) days of delivery of the Audited and Adjusted  Closing  Balance  Sheet.
     Any adjustment made under this Section 2.11 shall be allocated  19/27ths to
     the Redemption Price and 8/27ths to the Stock Purchase Price.

2.12 Example.  An example of the foregoing  Redemption  Price and Stock Purchase
     Price  adjustments,  escrow  arrangements and funding mechanics is attached
     hereto as Schedule 2.12.

2.13 Closing.

               (a)  Deliveries.  In the  event  that  all of the  conditions  to
          Closing (as defined in paragraph  (b) below) set forth in Sections 7.1
          and 7.2 have been  satisfied  or  waived,  the  parties  hereto  shall
          deliver to the appropriate other parties all certificates,  documents,
          exhibits, schedules and other instruments reasonably  




                                       10

<PAGE>



     required  to be  delivered  at  Closing  by  the  parties  or  their
     respective counsel pursuant to this Agreement, each of which shall be fully
     executed and  completed,  as  appropriate,  and (i) the Financing  Proceeds
     shall be  remitted  in  immediately  available  funds to the  Company to be
     utilized to fund the  Redemption,  (ii) the Company shall remit or cause to
     be remitted to Cerberonics  the Net Redemption  Price,  (iii) the Investors
     shall remit or cause to be remitted in immediately  available  funds to the
     Company the  Investment  Price for the purchase and sale of the  Investment
     Shares,  (iv)  the  Investors  shall  remit  or  cause  to be  remitted  in
     immediately  available  funds to Manoogian the Net Stock Purchase Price for
     the purchase and sale of the Manoogian  Shares,  and (v) the Escrow Account
     shall be funded.

               (b)  Time  and  Place.   The  closing  (the   "Closing")  of  the
          Transactions shall occur at the offices of Arent Fox Kintner Plotkin &
          Kahn at 10:00 a.m.,  local time,  on a date which is no later than one
          (1) business day after the Cerbco stockholders' meeting is convened to
          vote on the Redemption in accordance  with Section 5.2,  provided that
          as of said date all of the conditions to Closing set forth in Sections
          7.1 and 7.2 have been satisfied by the responsible  party or waived by
          the party benefitted  thereby and thus entitled to waive the same (the
          "Closing Date"), or such other time as the Investors,  the Company and
          the Stockholders may mutually agree.

2.14 Consequence of Delay in Closing.  Notwithstanding  anything to the contrary
     in this  Agreement,  in the event the Closing occurs after the  Transaction
     Date,  and such delay is not caused by an act or omission of the Investors,
     then the effective date of the Closing shall be the Transaction  Date, such
     that  the  Preliminary   Closing  Balance  Sheet  shall  be  based  on  the
     Transaction  Date  and the Cash  Flow (as  defined  below)  of the  Company
     subsequent to the Transaction Date shall be retained by the Company for the
     benefit of its  stockholders  (post-Closing).  For purposes  hereof,  "Cash
     Flow"  shall be  defined  as the  Company's  net  income  (after  tax) plus
     non-cash expenses such as depreciation and amortization, less any increases
     in Working Capital and any capital expenditures.


                                   ARTICLE III
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY
                                AND STOCKHOLDERS

     In making the  representations  and  warranties  set forth below,  the term
"material" shall be deemed to mean an amount of money greater than $50,000,  the
terms "material  adverse change,"  "material  adverse trend,"  "material adverse
effect,"  or any other  term of like  import  shall mean the  occurrence  of any
single event, or any series of related events, or set of related  circumstances,
which proximately causes an actual,  direct economic loss to the Company,  taken
as a whole,  in excess of $50,000 per  occurrence or $100,000 in the  aggregate.
The term "knowledge," as used in connection with any representation  made by the
Cerberonics   Parties,   shall  (i)  mean  actual  knowledge  of  the  Eriksons,
Cerberonics or Cerbco after reasonable investigation and (ii) be deemed to exist
with respect to any matter for which a reserve was provided for in the Company's
financial  statements,  regardless of whether the reserve is sufficient to cover
any loss in respect of such matter. Subject to the foregoing, in connection with
the Transactions, the Company and the Stockholders jointly and severally (except
as set forth in Sections  3.29 and 3.30)  represent and warrant to the Investors
as set forth in this Article III:

3.1  Capitalization.  Immediately prior to the Closing,  the authorized  capital
     stock of the Company is as described in Recital A above; provided, however,
     that as of the Closing  Date and  pursuant to Section 2.1 hereof,  prior to
     the  consummation  of the  Transactions,  the Company will  consummate  the
     Recapitalization  so as to have  10,000  shares of Class A  Common,  10,000
     shares of Class B Common  and 100 shares of Class C Common  authorized,  of
     which  742.5,  445.5  and 12  shares,  respectively,  will  be  issued  and
     outstanding.  All of the outstanding shares of capital stock of the Company
     are duly authorized, validly issued, fully paid, and nonassessable.  All of
     the outstanding shares of capital stock of the Company are owned of record




                                       11

<PAGE>



          and  beneficially  by  the  Stockholders,  with  Cerberonics  owning
          two-thirds and Manoogian owning one-third of such shares, as set forth
          in Part 1 (pre-Recapitalization) and Part 2 (post-Recapitalization) of
          Schedule  2. None of the  outstanding  shares of capital  stock of the
          Company was issued or will be transferred pursuant to the transactions
          contemplated  by this  Agreement  in violation  of any  preemptive  or
          preferential rights of any Person.

     3.2  Issuance of the Investment Shares. The issuance,  sale and delivery of
          the Investment Shares in accordance with this Agreement have been duly
          authorized  by all  necessary  corporate  action  on the  part  of the
          Company,  and the Investment Shares when so issued, sold and delivered
          against  payment  therefor in accordance  with this  Agreement will be
          duly and  validly  issued,  fully  paid and  nonassessable.  Except as
          provided in this  Agreement,  there are no  statutory  or  contractual
          stockholders  preemptive  rights with  respect to the  issuance of the
          Investment  Shares   hereunder.   Based  in  part  on  the  investment
          representations  of the  Investors in Section 4.4, the Company has not
          violated any applicable federal or state securities laws in connection
          with the offer,  sale or issuance of any of its capital stock, and the
          offer,  sale and issuance of the  Investment  Shares  hereunder do not
          require  registration under the Securities Act or any applicable state
          securities laws.

     3.3  Other  Rights to Acquire  Capital  Stock.  Except as set forth in this
          Agreement,  there are no authorized or outstanding warrants,  options,
          or rights of any kind to acquire  from the  Company any equity or debt
          securities  of  the  Company,   or  securities   convertible  into  or
          exchangeable  for equity or debt securities of the Company,  and there
          are no shares of capital  stock of the Company  reserved  for issuance
          for any  purpose nor any  contracts,  commitments,  understandings  or
          arrangements  which require the Company to issue,  sell or deliver any

     3.9  Properties.  Attached  hereto as Schedule  3.9 is a list  containing a
          description  of all  interests in real  property  (including,  without
          limitation, leasehold interests) and personal property utilized by the
          Company in the conduct of the  Business  having a book value in excess
          of $25,000 as of the date  hereof.  Except as  expressly  set forth on
          Schedule 3.9 (or in respect of the  Company's  accounts  receivable or
          Inventory,  on Schedule 3.20),  such real and personal  properties are
          free and  clear of  Encumbrances.  The  Investors  have  reviewed  the
          results  of a lien  search  covering  all of the  Company's  real  and
          personal  property  in the States of  Virginia  and  Maryland  and the
          District of Columbia.  All of the properties  and assets  necessary in
          the Business as currently  conducted  (including,  without limitation,
          all  books,   records,   computers  and  computer  software  and  data
          processing  systems) are owned,  leased or licensed by the Company and
          are suitable for the purposes for which they are currently being used.
          The material  physical  properties of the Company,  including the real
          properties leased by the Company,  are in good operating condition and
          repair,  normal wear and tear excepted,  and are free from any defects
          of a material  nature.  Except as otherwise set forth on Schedule 3.9,
          the Company has full and unrestricted legal and equitable title to all
          such  properties  and assets.  The  operation  of the  properties  and
          Business  of the  Company in the manner in which they are now and have
          been  operated  does not  violate  any  zoning  ordinances,  municipal
          regulations,  or  other  Requirements  of  Laws,  except  for any such
          violations which would not,  individually or in the aggregate,  have a
          Material  Adverse  Effect.  Except as set forth on  Schedule  3.9,  no
          covenants,  easements,  rights-of-way, or regulations of record impair
          the uses of the  properties  of the Company for the purposes for which
          they are now operated.  All leases of real or personal property by the
          Company are legal, valid,  binding,  enforceable and in full force and
          effect and will remain legal, valid, binding,  enforceable and in full
          force and effect on identical terms immediately following the Closing.
          The  Company has  obtained  all  required  material  approvals  of any
          Governmental  Body  (including  Governmental  Permits)  required to be
          obtained by the Company in connection with the operation thereof,  and
          the  facilities  owned or leased by the Company have been operated and
          maintained by the Company in accordance with all Requirements of Laws.

          all   material   licenses,   certificates,   privileges,   immunities,
          approvals, franchises,  authorizations and permits held or applied for
          by the Company from any Governmental Body (herein  collectively called
          "Governmental  Permits")  the  absence of which  could have a Material
          Adverse Effect. The Company has complied in all material respects with
          the terms and  conditions  of all such  Governmental  Permits,  and no
          violation of any such Governmental  Permit or the Requirements of Laws
          governing  the  issuance or  continued  validity  thereof has occurred
          other than violations (if any) which would not  individually or in the
          aggregate have a Material  Adverse  Effect.  No additional  Government
          Permit is required  from any  Governmental  Body thereof in connection
          with the conduct of the Business  which  Governmental  Permit,  if not
          obtained, would have a Material Adverse Effect.

     3.11 Intellectual Property.  Attached hereto as Schedule 3.11 is a list and
          brief description of all patents, trademarks,  tradenames, copyrights,
          licenses,  computer  software or data (other than  general  commercial

          registered  in the name of the Company or in which the Company has any
          rights,  licenses,  or  immunities  (collectively,  the  "Intellectual
          Property"). The Company has furnished the Investors with copies of all
          license agreements to which the Company is a party, either as licensor
          or licensee,  with  respect to any  Intellectual  Property.  Except as
          described on Schedule 3.11 hereto, the Company has good and marketable
          title to or the right to use such Intellectual Property 




                                       14

          and all inventions,  processes,  designs,  formulae, trade secrets
          and  know-how  necessary  for  the  conduct  of its  Business,  in its
          Business as presently  conducted without the payment of any royalty or
          similar  payment,  and the  Company  is not  infringing  on any patent
          right,  tradename,  copyright or trademark right or other Intellectual
          Property right of others, and neither the Company nor the Stockholders
          are aware of any  infringement  by others of any such rights  owned by
          the Company.

     3.12 Compliance  with Laws.  The Company has (i)  complied in all  material
          respects with all Requirements of Laws, Governmental Permits and Court
          Orders  applicable  to the  Business  and has  filed  with the  proper
          Governmental  Bodies  all  statements  and  reports  required  by  all
          Requirements of Laws,  Governmental  Permits and Court Orders to which
          the Company or any of its  employees  (because of their  activities on
          behalf of the Company) are subject and (ii) conducted the Business and
          is in compliance in all material respects with all federal,  state and
          local  energy,  public  utility,   health,  safety  and  environmental

          the Clean Air Act, the Clean Water Act,  RCRA, the Safe Drinking Water
          Act, CERCLA,  OSHA, the Toxic  Substances  Control Act and any similar
          state,   local   or   foreign   laws   (collectively    "Environmental
          Obligations")  and  all  other  federal,   state,   local  or  foreign
          governmental and regulatory requirements,  except, in the case of both
          (i) and (ii) above, where any such failure to comply would not, in the
          aggregate,  have a Material Adverse Effect.  No claim has been made by
          any  Governmental  Body (and,  to the knowledge of the Company and the
          Stockholders,  no such claim is  anticipated)  to the effect  that the
          Business fails to comply,  in any respect,  with any  Requirements  of
          Laws,  Governmental  Permit  or  Environmental  Obligation  or  that a
          Governmental Permit or Court Order is necessary in respect thereto.

          Copies  of all such  insurance  policies  have been  delivered  to the
          Investors.  No event  relating to the Company has occurred  which will
          result in (i)  cancellation  of any such  insurance  policies;  (ii) a
          retroactive  upward  adjustment of premiums  under any such  insurance
          policies; or (iii) any prospective upward adjustment in such premiums.

          under any of the  Contracts,  and the Company has not waived any right
          under  any of the  Contracts.  Subject  to the  foregoing,  all of the
          Contracts to which the Company is a party are legal,  valid,  binding,
          enforceable and in full force and effect and will remain legal, valid,
          binding,  enforceable  and in full force and effect on identical terms
          immediately  after the Closing.  Except as set forth in Schedule 3.15,
          the Company has not guaranteed any obligations of any other Person.

     3.16 Claims and Proceedings. Attached hereto as Schedule 3.16 is a list and
          brief description of all material claims, actions, suits, proceedings,
          or investigations pending (or, to the Company's knowledge,  threatened
          against) or affecting the Company or any of its  properties or assets,
          at law or in equity, or before or by any court,  municipality or other
          Governmental  Body. Except as set forth on Schedule 3.16, none of such
          claims, actions, suits, proceedings,  or investigations will result in
          any material  liability  or loss to the  Company.  The Company has not
          been,  and  the  Company  is not  now,  subject  to any  Court  Order,
          stipulation,  or consent of or with any court or Governmental Body. No
          inquiry,  action  or  proceeding  has  been  asserted,  threatened  or
          instituted   to  restrain  or  prohibit   the   carrying  out  of  the
          transactions  contemplated  by  this  Agreement  or to  challenge  the
          validity of such  transactions  or any part thereof or seeking damages
          on account thereof.  Except as set forth on Schedule 3.16, there is no
          basis for any such valid claim or action.

     3.17 Taxes.

               (a) All Federal,  foreign,  state, county and local income, gross
          receipts,   excise,   property,   franchise,   license,   sales,  use,
          withholding, and other Taxes and all Tax Returns which are required to
          be filed by the  Company on or before the date  hereof have been filed
          within the time and in the manner  provided  by law,  and all such Tax
          Returns  are  true  and  correct  and   accurately   reflect  the  Tax
          liabilities  of the  Company.  No Tax  Returns  of the  Company or the
          Stockholders  are  presently  subject to an  extension  of the time to
          file. Other than as described in the proviso which follows, all Taxes,
          assessments,  penalties, and interest of the Company which have become
          due pursuant to such Tax Returns or any assessments received have been
          paid or  adequately  accrued on the  Company's  Financial  Statements;
          provided, however, in respect




                                       16

          of the gross receipts tax in Fairfax County,  Virginia  disclosed
          by the Company in Schedules  3.4(b) and 3.27, the Company will satisfy
          and  discharge  any such taxes prior to Closing.  The  provisions  for
          Taxes  reflected  on the balance  sheets  contained  in the  Financial
          Statements are adequate to cover all of the Company's Tax  liabilities
          for the  respective  periods  then  ended and all prior  periods.  The
          Company has not executed any presently  effective  waiver or extension
          of any statute of limitations  against  assessments  and collection of
          Taxes,  and there are no pending or  threatened  claims,  assessments,
          notices, proposals to assess, deficiencies,  or audits with respect to
          any such Taxes.  For  Governmental  Bodies  with  respect to which the
          Company does not file Tax Returns, no such government body has claimed
          that any of the  Company  is or may be  subject  to  taxation  by that
          government  body. The Company has withheld and paid all Taxes required
          to have been  withheld  and paid in  connection  with  amounts paid or
          owing to any employee,  stockholder,  creditor, independent contractor
          or other  party.  There  are no tax  liens on any of the  property  or
          assets of the Company.

               (b) Neither the  Company nor any other  corporation  has filed an
          election  under  section  341(f) of the Code that is applicable to the
          Company or any assets  held by the  Company.  The Company has not made
          any  payments,  is not  obligated to make any  payments,  and is not a
          party to any agreement that under certain circumstances could obligate
          it to make any payments  that will not be  deductible  under Code Sec.
          280G.  The Company has not been a United States real property  holding
          corporation  within  the  meaning  of Code Sec.  897(c)(2)  during the
          applicable period specified in Code Sec. 897(c)(1)(A)(ii). The Company
          is not a party  to any Tax  allocation  or  sharing  agreement.  Since
          September  1992,  the Company has not been (nor does the Company  have
          any  liability  for unpaid  Taxes  because it once was) a member of an
          affiliated  group during any part of which return year any corporation
          other than the Company also was a member of the affiliated  group. The
          Company has never made an election to be taxed under  subchapter  S of
          the Code.

               (c) No transaction  contemplated  by this Agreement is subject to
          withholding  under  Section  1445 of the Code  and no  stock  transfer
          taxes,  real estate  transfer  taxes or similar  taxes will be imposed
          upon the issuance and sale of the Shares pursuant to this Agreement.

     3.18 Personnel. Attached hereto as Schedule 3.18 is a list of the names and
          annual rates of compensation  of the directors and executive  officers
          of the Company, and of the employees of the Company whose annual rates
          of compensation  during the fiscal year ended June 30, 1996 (including
          base salary,  bonus and incentive pay) exceed (or by December 31, 1996
          are expected to exceed)  $75,000.  Schedule 3.18 also  summarizes  the
          bonus, profit sharing,  percentage  compensation,  company automobile,
          club membership,  and other like benefits,  if any, paid or payable to
          such directors,  officers,  and employees  during the Company's fiscal
          year ended June 30, 1996 and to the date  hereof.  Schedule  3.18 also
          contains  a brief  description  of all  material  terms of  employment
          agreements to which the Company is a party and all severance  benefits
          which any  director,  officer or  employee of the Company is or may be
          entitled to receive.  The  employee  relations of the Company are good
          and  there  is  no  pending  or  threatened  labor  dispute  or  union
          organization  campaign.  None  of the  employees  of the  Company  are
          represented  by any labor  union or  organization.  The  Company is in
          compliance  in all material  respects  with all  Requirements  of Laws
          respecting employment and employment  practices,  terms and conditions
          of employment,  and wages and hours, and are not engaged in any unfair
          labor  practices.  Neither the Company nor the  Stockholders  has been
          advised,  or has any reason to believe,  that any of the persons whose
          names are set forth on Schedule  3.18 or any other  employee  will not
          agree to remain employed by the Company after the  consummation of the
          transactions  contemplated  hereby.  There is no unfair labor practice
          claim against the Company before the National Labor  Relations  Board,
          or any  strike,  dispute,  slowdown,  or  stoppage  pending or, to the
          knowledge of the Company and the Stockholders,  threatened  against or
          involving the Company, and none has occurred.

     3.19 Business  Relations.  Neither the Company nor the Stockholders know or
          have any  reason  to  believe  that any  supplier  of the  Company  or
          customer  comprising  more than 5% of the  Company's  sales or service
          revenues  will  cease  to do  business  with  the  Company  after  the
          consummation of the




                                       17

<PAGE>



          Transactions  in  the  same  manner  and at the  same  levels  as
          previously conducted with the Company, except for any reductions which
          do not result in a Material  Adverse  Change.  Neither the Company nor
          the Stockholders  have received any notice of any material  disruption
          (including  delayed  deliveries  or  allocations  by suppliers) in the
          availability  of any  material  portion of the  materials  used by the
          Company  nor are the  Company or the  Stockholders  aware of any facts
          which could lead it  reasonably  to believe that the Business  will be
          subject to any such material disruption.

               (a) Accounts  Receivable.  All of the accounts,  notes, and loans

               this  Agreement  or referred to herein and except as disclosed in
               Schedule  3.28 hereto,  neither  this  Agreement,  the  Schedules
               hereto, nor any information, instrument, or document delivered to
               the  Investors  pursuant to this  Agreement  contains  any untrue
               statement of a material fact or omits any material fact necessary

               violation of the federal  securities laws or any applicable state
               securities  laws;  provided  that nothing  contained  herein will
               prevent  the  Investors  and  subsequent  holders  of  Restricted
               Securities from  transferring  such securities in compliance with
               the provisions of Section 6.2 hereof.

          4.5  No Undisclosed Agreement. Other than as described in the Exhibits
               hereto,   there  are  no  undisclosed   agreements   between  the
               Investors,  or any one of them,  or any  Affiliate of any of them

          paid (on a  pro-rated  basis  for the  partial  year in the  event the
          Closing  Date is before June 30,  1997)  prior to the Closing  Date as
          opposed  to  October  1997 as would  have been the case  under  normal
          circumstances),  change any bonus, insurance, pension, compensation or
          other  benefit  plan or  arrangement  made for or with or covering any
          officers  or  employees  of the  Company;  (v)  waive  any  rights  of

          dispose of or acquire  any  material  assets  outside of the  ordinary
          course of the Business, or agree to do any of the foregoing.

               (b) Conduct of Business.  The Company  will and the  Stockholders
          shall cause the Company to continue to record its  transactions and to
          prepare its financial  statements  consistently and in accordance with
          GAAP,  consistent  with  past  practice.  The  Company  will  and  the
          Stockholders shall cause the Company to preserve  substantially intact
          its  business   organization  and  present   relationships   with  its
          customers,  suppliers  and  employees  and  to  maintain  all  of  its

               (c) Nature of Breach. The Company shall give prompt notice to the

          Closing Date.

               (d) No Solicitation.

                                    (i)  Immediately  following the execution of
                  this Agreement, the Company and the Stockholders will and will
                  use their best efforts to cause each of their  representatives
                  (including such parties' employees,  counsel, investment bank,
                  accountants,  and  similar  consultants  and  representatives)
                  ("Representatives")   to   terminate   any  and  all  existing
                  activities,  discussions and  negotiations  with third parties
                  (other  than   Investors)   with   respect  to  any   possible
                  transaction involving the acquisition of the Company's capital
                  stock or assets or the merger or other business combination of
                  the Company with or into any such third party.

                                    (ii) The Company and the  Stockholders  will
                  not  (and  will  use  their  best   efforts  to  cause   their
                  Representatives   not  to)  solicit,   initiate  or  knowingly
                  encourage the  submission of, any offer or proposal to acquire
                  all or any part of the capital  stock of the Company or all or
                  any material  portion of the assets or business of the Company
                  (other than the transactions  contemplated by this Agreement),
                  whether by merger,  purchase of stock or assets, tender offer,
                  exchange  offer  or  otherwise  (an  "Alternative  Proposal"),
                  provided,  however,  that, if the Company, the Stockholders or
                  any of their  Representatives  shall  receive  an  Alternative
                  Proposal,   then  such   Representatives   may  discuss   such
                  Alternative   Proposal   with  the  Person   presenting   such
                  Alternative Proposal and provide information to such Person if
                  the board of  directors  of Cerbco  determines  in good faith,
                  after considering the advice of its legal counsel,  that it is
                  required to do so in order to discharge properly its fiduciary
                  duty to Cerbco's stockholders.

                                    (iii) The Company and the Stockholders  will
                  promptly communicate to the Investors the terms and conditions
                  of any  Alternative  Proposal  that they may  receive and will
                  keep the  Investors  informed  as to the status of any actions
                  (including any discussions with




                                       21

<PAGE>



                  any potential third party acquiror in the form of proposals or
                  counter-proposals)   taken   pursuant   to  such   Alternative
                  Proposal.

                                    (iv) If the Company or the  Stockholders  or
                  any of their  Representatives  receive an Alternative Proposal
                  and the board of directors of Cerbco determines in good faith,
                  after considering the advice of its legal counsel,  that it is
                  required to do so in order to discharge properly its fiduciary
                  duty to Cerbco's  stockholders,  then such Representatives may
                  negotiate the terms of such Alternative Proposal and a binding
                  definitive agreement with such Person with respect thereto (an
                  "Alternative Transaction").

                                    (v)  Nothing in this  Section  5.1(d)  shall
                  permit  the  Company or the  Stockholders  to  terminate  this
                  Agreement  except as  specifically  provided in Section 9.1 or
                  9.3.

               (e)  Access to  Information.  The  Stockholders  shall  cause the
          Company to afford the Investors  access,  during normal business hours
          and upon reasonable notice, to all of the assets,  properties,  books,
          records,  and  agreements  of the  Company,  and shall  furnish to the
          Investors and their  representatives  such  information  regarding the
          Company as the Investors may reasonably  request;  provided,  however,
          that any such investigation shall be conducted in such a manner as not
          to interfere unreasonably with the operation of the Business.

               (f) Transfers or Restrictions.  The Stockholders  shall not sell,
          transfer, pledge or grant a security interest in, or otherwise dispose
          of or encumber,  any of the outstanding shares of the capital stock of
          the Company without the consent of the Investors.

          5.2  Cerbco  Stockholders  Meeting.   Cerbco  shall  take  all  action
               necessary in accordance  with  applicable law and its certificate
               of  incorporation  and  by-laws  to  convene  a  meeting  of  its
               stockholders as promptly as practicable after the date hereof for
               the purpose of voting on the proposed Redemption (the "Redemption
               Proposal").  The board of  directors  of Cerbco  shall  recommend
               approval  of the  Redemption  Proposal  and shall take all lawful
               action to solicit such approval,  including the timely mailing of
               a Proxy Statement to the stockholders of Cerbco, which shall have
               been reviewed by the Investors.  It is acknowledged and agreed by
               the Investors that the Cerbco board of directors intends to seek,
               and condition the consummation of the Redemption on, the separate
               approval  of the  Redemption  Proposal by a majority of the votes
               cast by the non-Erikson stockholders of Cerbco, and that any such
               majority vote of the votes cast by the non-Erikson  stockholders,
               coupled with the votes of the Eriksons as provided in the Erikson
               Voting  Agreement,  shall be sufficient to approve the Redemption
               in accordance  with Delaware law and Cerbco's  corporate  charter
               documents.  Notwithstanding  the  above,  however,  it shall be a
               condition  to the  mailing of such Proxy  Statement  that  Cerbco
               shall have received an opinion from a qualified, independent firm
               of investment  bankers or financial  advisors  selected by Cerbco
               (which  opinion  shall be  acceptable  in form and  substance  to
               Cerbco) to the effect  that the  consideration  to be received in
               the  Redemption by Cerberonics is fair to Cerbco from a financial
               point of view,  and such opinion  shall not have been  withdrawn,
               revoked or modified;  provided,  however,  that the  compensation
               arrangements   with  such   investment  bank  shall  (i)  not  be
               contingent on the successful consummation of the Redemption,  and
               (ii)  provide  that  such bank  shall be  ineligible  to  receive
               compensation   in  connection   with  the   consummation  of  any
               Alternative Transaction consummated prior to the expiration of 18
               months  following the termination of this Agreement under Article
               IX.

          5.3  Consents of Others.  Prior to the Closing, the Stockholders shall
               use their  commercially  reasonable best efforts to obtain and to
               cause the  Company to obtain  all  authorizations,  consents  and
               permits  required  of the Company or the  Stockholders  to permit
               them to consummate the Transactions, including without limitation
               any consents required under the Canon License Agreement described
               on Schedule 3.11 or under any of the Company's leases.

          5.4  Stockholders' Efforts. The Company and the Stockholders shall use
               all reasonable efforts to cause all conditions for the Closing to
               be met.

          5.5  Powers of Attorney.  The Stockholders  shall cause the Company to
               terminate  at or prior to Closing all powers of attorney  granted
               by the Company,  other than those relating to service of process,
               qualification or pursuant to governmental regulatory or licensing
               agreements,  or representation before the IRS or other government
               agencies.

          5.6  Transfer  Taxes.  The  Stockholders  shall be responsible for and
               shall pay all stock  transfer or gains taxes (if any) incurred in
               connection  with the Redemption  (in the case of the  Cerberonics
               Parties) or the Stock Purchase (in the case of Manoogian).

          5.7  Notice of  Developments;  Update  of  Disclosure  Schedules.  The
               Company and the  Stockholders  will give prompt written notice to
               the Investors of any material  development  affecting the assets,
               liabilities, Business, financial condition, operations or results
               of  operations  of the  Company  and each party  hereto will give
               prompt written  notice to the others of any material  development
               affecting  the ability of any of such parties to  consummate  the
               Transactions.  The  Company and the  Stockholders  shall have the
               right,  for a period from the date of this Agreement to that date
               which is not later than fifteen (15)  business  days prior to the
               Closing Date, to update any of the disclosure  schedules provided
               under  Article  III;  provided,  however,  that if  such  updated
               schedules  reveal a change  that is  material  (defined as in the
               preamble to Article III), the Investors  shall notify the Company
               and the Stockholders within three (3) business days of receipt of
               such  updated  schedule  that the same  contains  such a material
               change.  If after a period  of ten (10)  business  days  from the
               receipt of the Investors' notice, the parties are unable to reach
               an agreement regarding an appropriate  adjustment to the Purchase
               Price  or  other  amendment  to this  Agreement  that  adequately
               compensates the Investors for the adverse impact of such material
               change,  then the  Investors  may,  at their  option,  either (i)
               terminate this Agreement  without  liability for the break-up fee
               set forth in the first sentence of Section 9.3, or (ii) waive the
               right to claim  that  such  matter  constitutes  a breach  of the
               representations  and warranties of this  Agreement  under Section
               7.1(b) or Article VIII.


                                   ARTICLE VI
                             POST-CLOSING COVENANTS

          6.1  General. In case at any time after the Closing any further action
               is legally  necessary  or  reasonably  desirable to carry out the
               purposes of this  Agreement,  each of the parties  will take such
               further  action  (including  the  execution  and delivery of such
               further  instruments and documents) as any other party reasonably
               may request,  all at the sole cost and expense of the  requesting
               party (unless the requesting party is entitled to indemnification
               therefor under Article VIII below). Each Stockholder acknowledges
               and agrees that from and after the  Closing  the Company  will be
               entitled  to  possession  of  all  documents,   books,   records,
               agreements,  and  financial  data  of any  sort  relating  to the
               Company,  which shall be maintained at the chief executive office
               of the Company; provided, however, that the Stockholders shall be
               entitled to reasonable access to and to make copies of such books
               and records at its sole cost and  expense  and the  Company  will
               maintain the books,  records and material financial data relating
               to the Company for a period of at least three (3) years.

          6.2  Litigation  Support.  In the  event  and for so long as any party
               actively  is   contesting   or  defending   against  any  charge,
               complaint,  action,  suit,  proceeding,  hearing,  investigation,
               claim,   or  demand  in  connection   with  (i)  any  transaction
               contemplated  under this  Agreement or (ii) any fact,  situation,
               circumstance,   status,  condition,   activity,  practice,  plan,
               occurrence,   event,   incident,   action,  failure  to  act,  or
               transaction  on or  prior  to  the  Closing  Date  involving  the
               Company, each of the other parties will cooperate with it and its
               counsel  in  the  contest  or  defense,   make  available   their
               personnel, and provide such testimony and




                                       23

<PAGE>



          access  to  their  books  and  records  as  shall  be  reasonably
          necessary in connection  with the contest or defense,  all at the sole
          cost and expense of the  contesting  or  defending  party  (unless the
          contesting or defending party is entitled to indemnification  therefor
          under Article VIII below).

          6.3  Transition.  For a period of three (3) years  following  Closing,
               the  Stockholders  will not take any  action  that  primarily  is
               designed  or  intended  to have the  effect of  discouraging  any
               lessor, licensor, customer, supplier, or other business associate
               of the Company from maintaining the same business  relations with
               the Company after the Closing as it  maintained  with the Company
               prior to the Closing.  For a period of three (3) years  following
               Closing,  the  Stockholders  will  refer all  customer  inquiries
               relating  to  the  Business  to  the   Company.   In  respect  of
               Manoogian's   commitment   pursuant  to  the  foregoing,   it  is
               acknowledged  that his agreement  thereto is in  consideration of
               his receipt of the Stock Purchase Price and is independent of any
               similar  agreement   pursuant  to  the  terms  of  the  Manoogian
               Executive Agreement.

          6.4  Confidentiality. The Stockholders will treat and hold as such all
               Confidential   Information,   refrain   from  using  any  of  the
               Confidential Information except in connection with this Agreement
               for a period of three (3) years  from the  Closing,  and  deliver
               promptly to the Company or destroy,  at the request and option of
               the  Company,  all tangible  embodiments  (and all copies) of the
               Confidential  Information  which are in its possession  except as
               otherwise  permitted  herein.  In  the  event  that  any  of  the
               Stockholders  is  requested  or  required  (by oral  question  or

                                   ARTICLE VII
            CONDITIONS TO OBLIGATION OF PARTIES TO CONSUMMATE CLOSING

          7.1  Conditions to the Investors'  Obligations.  The obligation of the
               Investors  under this  Agreement  to  consummate  the  Closing is
               subject to the conditions that:

               (a) Satisfaction with Due Diligence. The Investors shall have the
          right to conduct  their due diligence on the Company and the Business,
          and  it  is  a  condition   precedent  to  the   consummation  of  the
          Transactions  that the  Investors  shall be  satisfied in all material
          respects  with  their  due  diligence  investigation  of the  Company;
          provided,  however, that although the Investors may continue their due
          diligence  investigation up through the Closing Date, in order for the
          Investors  to  terminate  this  Agreement  due to the  results of such
          investigation  without  liability for the $1,000,000  break-up fee set
          forth in the first  sentence of Section 9.3, the Investors must notify
          the  Company and the  Stockholders  on or before the 60th day from the
          date of this Agreement that it has found a material  adverse matter or
          problem in the course of such  investigation  such that the reasonably
          demonstrable  impact on the Purchase  Price (whether as a result of an
          individual  adverse matter or problem or in the aggregate for all such
          adverse  matters or problems) (the "Impact") is in excess of $100,000.
          Failure by the  Investors  to provide  such notice  within such 60-day
          period shall  constitute a waiver by the  Investors of this  condition
          precedent.  Any  such  notice  shall  contain  a  reasonably  detailed
          description  of  such  matter  or  problem  and  the  Company  and the
          Stockholders  shall have 15 days to either (i)  resolve  the matter or
          cure the problem to the Investors'  reasonable  satisfaction,  or (ii)
          after good faith negotiations by all parties,  reach an agreement with
          the  Investors  regarding an  appropriate  adjustment  to the Purchase
          Price or other amendment to this Agreement that adequately compensates
          the  Investors for the adverse  impact of such matter or problem.  For
          the purposes of the previous sentence,  reducing the Purchase Price by
          an amount equal to the Impact shall be deemed  reasonable.  Failure of
          either (i) or (ii) to occur  within  such  15-day  period  may, at the
          option of the Investors,  result in a termination of this Agreement by
          the  Investors  (again,  without  liability for any break-up fee under
          Section  9.3).  If no such notice is delivered by the  Investors on or
          before the 60th day from the date of this Agreement, and the Investors
          terminate   this   Agreement  as  a  result  of  their  due  diligence
          investigation, then provided that neither Section 9.1(c) or any of the
          other




                                       24

<PAGE>



          termination  triggers  under  Section  9.1  are  applicable,  the
          Investors shall owe the break-up fee required by the first sentence of
          Section 9.3.

               (b) Covenants,  Representations  and Warranties.  The Company and
          the  Stockholders  shall have  performed in all material  respects all
          obligations and agreements and complied in all material  respects with
          all covenants contained in this Agreement to be performed and complied
          with  by  any  of  them  prior  to  or  at  the  Closing   Date.   The
          representations and warranties of the Company and the Stockholders set
          forth in this Agreement shall be accurate in all material  respects at
          and as of the  Closing  Date with the same  force and effect as though
          made on and as of the Closing  Date  except for any changes  resulting
          from activities or  transactions  which may have taken place after the
          date hereof and which are permitted or  contemplated by this Agreement
          or which have been entered into in the ordinary course of business and
          except to the extent  that such  representations  and  warranties  are
          expressly  made  as  of  another   specified  date  and,  as  to  such
          representation, the same shall be true as of such specified date.

               (c) Hart-Scott-Rodino; Other Consents. All statutory requirements

          the  consummation of the transactions  contemplated  hereby shall have
          been obtained in form and  substance  reasonably  satisfactory  to the
          Investors  unless  such  failure  shall  not have a  Material  Adverse
          Effect.  In addition,  the Company  shall have obtained a consent from
          Canon under the License Agreement  described on Schedule 3.11, if same
          is required  under the terms thereof as a result of the  Transactions.

          shall  have  approved  the  consummation  of  this  Agreement  and the
          transactions contemplated hereby.

               (d)  Cash  on  Balance   Sheet.   The  Company's  cash  and  cash
          equivalents immediately prior to Closing shall on a consolidated basis
          be not less than  $800,000,  if the Closing  Date occurs  prior to the
          Transaction Date. If the Closing Date is subsequent to the Transaction
          Date,  then in accordance  with Section 2.14,  the Company's  cash and
          cash equivalents shall be not less than $800,000 as of the Transaction
          Date  plus the cash  component  of the  Company's  net  income  on the
          Closing Date.

               (e) Discharge of Indebtedness and Encumbrances.  The Stockholders
          and the  Company  shall have  provided  for the payment in full of all
          Funded  Indebtedness  of the  Company  and all  extended  credit  from
          vendors at the Closing.  Such Funded  Indebtedness  as of December 31,
          1996 is listed on Schedule 7.1(e) hereto.  The Stockholders shall have
          also  caused  the  Company  to have  terminated  or  provided  for the

          all  material  respects  with all  covenants  contained in the Erikson

                                  ARTICLE VIII
                                 INDEMNIFICATION





                                       27

<PAGE>



               Notwithstanding  anything to the  contrary in this  Agreement,
the  Investors,  the  Company  and  the  Stockholders  shall  have no  claim  of
entitlement  for  reimbursement  of losses or damages in any way  related to the
Transactions under this Agreement except as provided in this Article VIII.

          8.1  Indemnification  by the Stockholders.  The Stockholders agree to,
               individually  and not jointly and  severally,  indemnify and hold
               harmless  the  Investors or the Company  (post-Closing)  and each
               officer,  director,  and affiliate of any Investor or the Company
               (post-Closing) (collectively, the "Indemnified Parties") from and
               against  any  and  all  damages,  losses,  claims,   liabilities,
               demands, charges, suits, penalties, costs and expenses (including
               court costs and reasonable  attorneys' fees and expenses incurred
               in investigating  and preparing for any litigation or proceeding)
               (collectively,  the  "Indemnifiable  Costs"),  which  any  of the
               Indemnified   Parties  may  sustain,  or  to  which  any  of  the
               Indemnified  Parties  may be  subjected,  arising  out of (A) any
               misrepresentation,  breach or default by the  Stockholders or the
               Company   (pre-Closing)   of  or  under  any  of  the  covenants,
               agreements or other provisions of this Agreement or any agreement
               or document  executed in connection  herewith;  (B) the assertion
               and final  determination of any claim or liability against any of
               the Indemnified  Parties by any Person based upon the facts which
               form the alleged basis for any litigation to the extent it should
               have been, but was not, reserved for in the Financial  Statements
               in accordance with GAAP; and (C) the Company's (pre-Closing) or a
               Stockholder's  tortious acts or omissions to act prior to Closing
               for which the Company did not carry liability insurance,  whether
               or not such  acts or  omissions  to act  result  in a  breach  or
               violation of any  representation  or warranty.  Determination  of
               whether the Company,  on the one hand, or the  Investors,  on the
               other hand,  is entitled to  indemnification  hereunder  shall be
               made by such  parties  in light of the  economic  impact  or loss
               caused  by the  matter  which  is the  subject  of the  claim  of
               indemnification.  By way of example,  a claim of  indemnification
               for breaches of the  representation  made in Section 3.17 (Taxes)
               would impact the Company so that the Company would be entitled to
               indemnification.  A claim of indemnification based on a breach of
               Section  3.29 (No Liens on Shares)  would  affect the  Investors'
               investment in the Company directly (as opposed to  derivatively),
               so that the Investors would be entitled to indemnification.

          8.2  Defense of Claims.  If any legal  proceeding shall be instituted,
               or any claim or demand  made,  against any  Indemnified  Party in
               respect of which the Stockholders may be liable  hereunder,  such
               Indemnified Party shall give prompt written notice thereof to the
               Stockholders  and,  except as  otherwise  provided in Section 8.4
               below, the Stockholders  shall have the right to defend, or cause
               the Company or its successors to defend, any litigation,  action,
               suit,  demand,  or claim for which they may seek  indemnification
               unless,  in  the  reasonable  judgment  of  the  Investors,  such
               litigation,  action,  suit,  demand,  or claim, or the resolution
               thereof,  would  have an  ongoing  effect on the  Investors,  the
               Company  or its  successors,  and such  Indemnified  Party  shall
               extend  reasonable  cooperation in connection  with such defense,
               which  shall be at the  Stockholders'  expense.  In the event the
               Stockholders  fail to defend the same within a reasonable  length
               of  time,  the   Indemnified   Parties  and/or  the  Company  (as
               appropriate) shall be entitled to assume the defense thereof, and
               the Stockholders shall be liable to repay the Indemnified Parties
               and/or the Company (as appropriate)  for all expenses  reasonably
               incurred in connection  with said defense  (including  reasonable
               attorneys' fees and settlement payments) if it is determined that
               such request for  indemnification was proper. If the Stockholders
               shall not have the right to assume the defense of any litigation,
               action,  suit,  demand, or claim in accordance with either of the
               two preceding  sentences,  the Indemnified Parties shall have the
               right to control the  defense of and to settle,  with the consent
               of the  Stockholders,  which  consent  shall not be  unreasonably
               withheld,  such litigation,  action,  suit, demand, or claim, but
               the  Stockholders  shall be entitled,  at their own  expense,  to
               participate in such litigation, action, suit, demand, or claim.

          8.3  Escrow  Claim.  If any  claim for  indemnification  is made by an
               Indemnified  Party  pursuant  to this  Article  VIII prior to the
               expiration of the Escrow Period, such Indemnified Party may apply
               to the Escrow Agent provided in Section 2.7 of this Agreement for
               reimbursement  of such claim in accordance with the provisions of
               the Escrow Agreement.

          8.4  Tax Audits,  Etc. In the event of an audit of a Tax Return of the
               Company  with  respect  to which an  Indemnified  Party  might be
               entitled to  indemnification  pursuant to this Article VIII,  the
               Stockholders   shall  have  the  right  in  proportion  to  their
               respective  interest  in the  Company  prior to the  consummation
               hereof,  to control any and all such  audits  which may result in
               the  assessment of  additional  Taxes against the Company and any
               and all subsequent proceedings in connection therewith, including
               appeals  (subject to the prior written  consent of the Investors,
               which shall not  unreasonably  be withheld).  The Company and the
               Stockholders  shall  each  cooperate  fully with the other in all
               matters  relating  to any  such  audit or  other  Tax  proceeding
               (including  according access to all records pertaining  thereto),
               and  will  execute  and  file  any and all  consents,  powers  of
               attorney, and other documents as shall be reasonably necessary in
               connection  therewith.  If  additional  Taxes are  payable by the
               Company  as a result of any such audit or other  proceeding,  the
               Stockholders  shall be  responsible  for and shall  promptly  pay
               their proportionate share of all Taxes,  interest,  and penalties
               to which any of the  Indemnified  Parties  shall be  entitled  to
               indemnification.

          8.5  Indemnification   of  the  Stockholders  and  the  Company.   The
               Investors  agree,  on a joint and several basis, to indemnify and
               hold harmless the  Stockholders and the Company and each officer,
               director,  stockholder  or  affiliate  of the  Company,  from and
               against  any   Indemnifiable   Costs   arising  out  of  (A)  any
               misrepresentation, breach or default by the Investors of or under
               any of the  covenants,  agreements  or other  provisions  of this
               Agreement  or any  agreement or document  executed in  connection
               herewith and (B) any tortious  acts or omissions by the Investors
               or the Company  after the Closing.  In addition,  the Company and
               the Investors shall indemnify the Stockholders for any payment by
               the Stockholders of the Company's obligations occurring after the
               Closing Date.

          8.6  Limits on  Indemnification.  Except  for any claims for breach of
               the  representations  and  warranties of the  Stockholders  under
               Sections 3.1, 3.2, 3.3, 3.17 or 3.29 hereof (the  indemnification
               for  which  shall  expire  on the  expiration  of the  applicable
               statute of limitations),  the indemnification provided under this
               Article  VIII shall  expire  twelve  (12) months from the Closing
               Date. The Stockholders  shall not be obligated to pay any amounts
               for  indemnification  under this Article VIII until the aggregate
               indemnification  obligation hereunder exceeds $50,000,  whereupon
               the  Stockholders  shall only be liable for all amounts in excess
               of  such  $50,000  for  which   indemnification  may  be  sought.
               Notwithstanding the foregoing,  in no event shall any Stockholder
               have any liability to the Investors in excess of their  allocable
               portion of ten  percent  (10%)  (i.e.,  allocated  7.0379% to the
               Cerberonics  Parties and 2.963% to  Manoogian)  of the sum of (i)
               the Redemption  Price,  as adjusted by Sections 2.8 and 2.11, and
               (ii) the Stock  Purchase  Price,  as adjusted by Sections 2.8 and
               2.11   (except   for   claims   made  for  any   breach   of  the
               representations and warranties of the Stockholders under Sections
               3.1, 3.2, 3.3, 3.17 or 3.29 hereof,  for which no such limitation
               on the Stockholders' indemnification obligations shall apply). In
               addition,  (i) the  Cerberonics  Parties shall only be liable for
               breaches  of the  representations  and  warranties  contained  in
               Sections 3.8 through 3.20, 3.23, 3.24, 3.25, 3.27 and 3.28 to the
               extent it or the  Eriksons  had actual  knowledge of such breach,
               (ii) the Cerberonics Parties shall only be liable for breaches of
               the representations  and warranties  contained in Section 3.29 to
               the extent such breach  relates to the  Cerberonics  Shares,  and
               (iii)  Manoogian  shall  only  be  liable  for  breaches  of  the
               representations  and warranties  contained in Section 3.29 to the
               extent such breach relates to the Manoogian Shares and shall have
               no liability for breaches of the  representations  and warranties
               made by the  Cerberonics  Parties under  Section  3.30.  However,
               nothing in this Article VIII shall limit the Investors in any way
               in  exercising  or securing any remedies  provided by  applicable
               common law with  respect to the  conduct of the  Stockholders  in
               connection  with this  Agreement or in the amount of damages that
               it can  recover  from  the  Stockholders  in the  event  that the
               Investors  successfully  prove  intentional  fraud or intentional
               fraudulent conduct in connection with this Agreement.

                                   TERMINATION

          9.1  Termination.  This  Agreement may be terminated at any time prior
               to the Closing:

               (a)  Mutual  Consent.  Upon the  mutual  written  consent  of all
          parties hereto;

               (b)  Litigation.  By either  Stockholder  or the  Company  or the
          Investors if an  injunction or other order shall have been issued by a
          court or administrative body of competent jurisdiction,  or litigation
          or a governmental  proceeding  shall be pending or  threatened,  which
          restrains  or seeks to restrain or otherwise  would make  unlawful the
          consummation of the transactions contemplated by this Agreement;

               (c) Conditions to the Investors' Obligations. By the Investors if
          any of the  conditions  provided in Section 7.1 hereof  shall not have
          been satisfied,  complied with or performed in any material respect on
          or before the Closing Date and the Investors  shall not have waived in
          writing   such   failure   of    satisfaction,    non-compliance    or
          non-performance;

               (d)   Conditions   to  the   Stockholders'   and  the   Company's
          Obligations.  By  the  Stockholders  and  the  Company  if  any of the
          conditions  provided  in  Section  7.2  hereof  shall  not  have  been
          satisfied,  complied  with or performed in any material  respect on or
          before  the  Closing  Date,  and the  Stockholders  have not waived in
          writing   such   failure   of    satisfaction,    non-compliance    or
          non-performance;

               (e)  Alternative  Transaction.  By  Cerbco  if  (i)  Cerbco,  the
          Stockholders  and/or the Company is (or are)  prepared to enter into a
          binding definitive agreement to effect an Alternative Transaction; and
          (ii) the Company,  the Stockholders  and/or Cerbco has (or have) given
          the  Investors  at  least  five (5)  business  days'  notice  of their
          intention to terminate this Agreement  pursuant to this Section 9.1(e)
          (which notice shall include a  description  of all relevant  terms and
          conditions  of such  Alternative  Transaction),  during  which  period
          Investors  shall  have  the  opportunity  to  propose   amendments  or
          modifications to the terms of the Redemption and the Stock Purchase;

               (f) Withdrawal of Cerbco Board Approval.  By the Investors if the
          Cerbco  board of directors  shall have  amended or withdrawn  any such
          recommendation and such  recommendation is not reinstated in its prior
          form within five (5) business days after such  amendment or withdrawal
          other than as a result of the events  described in  paragraphs  (g) or
          (h) below;

               (g) Lack of  Favorable  Fairness  Opinion.  By the  Investors  or
          Cerbco if the Cerbco board of directors shall have failed to recommend
          adoption of the Redemption Proposal at the time the Proxy Statement is
          first  mailed to  Cerbco's  stockholders  and such  failure  is due to
          Cerbco having  obtained,  pursuant to Section 5.2, a fairness  opinion
          that is not favorable; or

               (h) Rejection by Cerbco Stockholders.  By the Investors or Cerbco
          if the  stockholders  of  Cerbco  shall  have  failed to  approve  the
          Transaction at meetings duly convened therefore in accordance with the
          terms of Sections 5.2 and 7.1(i).

          9.2  Effect of  Termination.  Termination of this Agreement by a party
               pursuant  to this  Article  IX shall not of itself  result in any
               liability on such party or his or its respective representatives,
               directors,  officers,  stockholders  or  agents.  In the event of
               termination of this Agreement,  nothing contained in this Section
               9.2 shall relieve any party from liability for any breach of this
               Agreement.

          9.3  Fees and Expenses.  If (i) the Investors terminate this Agreement
               at any time  under  circumstances  where  the  provisions  of and
               events described by Section 9.1(a), (b), (c), (f), (g) or (h) are
               not

          applicable,   or  (ii)  the  Investors  fail  to  consummate  the
          Transactions  through no fault of the Stockholders or the Company, and
          the  Company  and  the  Stockholders  have  otherwise   satisfied  all
          conditions  precedent  applicable  to such parties  under Section 7.1,
          then the  Investors  shall,  jointly and  severally,  promptly pay the
          Stockholders  (19/27ths to Cerberonics and 8/27ths to Manoogian) a fee
          equal to  $1,000,000  (subject,  however,  to the operation of Section
          7.1(a)). If this Agreement is terminated pursuant to Section 9.1(e) or
          (f), Cerbco shall promptly pay Investors a fee equal to $1,000,000. If
          this Agreement is terminated pursuant to Section 9.1(g) or (h), Cerbco
          shall  promptly pay  Investors a fee equal to (i) $250,000 in same day
          funds (such amount being a reasonable  estimate of the Investors costs
          and expenses) and (ii) if an  Alternative  Transaction  is consummated
          within one (1) year following such termination, an additional $750,000
          shall be payable by Cerbco to the Investors upon such  consummation of
          the Alternative  Transaction.  Any such fees shall be paid in same day
          funds and in no event later than one business day after termination of
          this  Agreement  and shall bear  interest on such amount from the date
          payable  until  paid  at a rate  of  eight  percent  (8%)  per  annum.
          Notwithstanding  anything  to the  contrary  in this  Article  IX, any
          termination  by either party under  Sections  9.1(e),  (f), (g) or (h)
          shall not be effective  until  Investors have received  payment of the
          $1,000,000 fee payable pursuant to the second sentence of this Section
          9.3 in the case of a termination  under Sections 9.1(e) or (f), or the
          $250,000 fee payable  pursuant to clause (i) of the third  sentence of
          this Section 9.3 in the case of a termination  under Section 9.1(g) or
          (h).

                                  MISCELLANEOUS

          10.1 Modifications.  Any  amendment,  change or  modification  of this
               Agreement  shall be void  unless  in  writing  and  signed by all
               parties  hereto.  No  failure  or delay by any  party  hereto  in
               exercising any right, power or privilege hereunder (and no course
               of dealing  between or among any of the parties) shall operate as
               a waiver of any such right, power or privilege.  No waiver of any
               default  on any one  occasion  shall  constitute  a waiver of any
               subsequent or other default. No single or partial exercise of any
               such right, power or privilege shall preclude the further or full
               exercise thereof.

          10.2 Notices. All notices and other communications  hereunder shall be
               in  writing  and shall be deemed  to have  been duly  given  when

               and  agreements   referred  to  herein,   constitute  the  entire
               agreement  between the  parties  hereto and  supersede  all prior

               hereof.

          10.7 Governing  Law. This  Agreement  and its validity,  construction,
               enforcement,   and  interpretation   shall  be  governed  by  the

          10.8 Survival of Representations, Warranties and Covenants. Regardless
               of any  investigation  at any time  made by or on  behalf  of any
               party hereto or of any  information any party may have in respect
               thereof,   all  covenants,   agreements,   representations,   and
               warranties and the related indemnities made hereunder or pursuant
               hereto or in connection with the transactions contemplated hereby

               of this Agreement, and the related indemnities, shall survive the
               Closing  until  the  expiration  of the  applicable  statutes  of

               the  representations  and  warranties  contained in Sections 3.1,
               3.2, 3.3 and 3.29 of this Agreement, and the related indemnities,
               shall survive the Closing indefinitely.

          10.9 Invalid Provisions.  If any provision of this Agreement is deemed
               or held to be illegal,  invalid or unenforceable,  this Agreement
               shall  be  considered   divisible  and  inoperative  as  to  such
               provision  to the extent it is deemed to be  illegal,  invalid or
               unenforceable,  and in all other  respects this  Agreement  shall
               remain in full force and effect;  provided,  however, that if any
               provision  of this  Agreement  is deemed  or held to be  illegal,
               invalid   or   unenforceable   there   shall  be   added   hereto
               automatically a provision as similar as possible to such illegal,
               invalid  or  unenforceable  provision  and be  legal,  valid  and
               enforceable.  Further,  should any  provision  contained  in this
               Agreement  ever be reformed or rewritten by any judicial  body of
               competent   jurisdiction,   such  provision  as  so  reformed  or
               rewritten shall be binding upon all parties hereto.

          10.10 Public  Announcements.  Neither  party  shall  make  any  public
               announcement of the transactions  contemplated hereby without the
               prior written consent of the other party, which consent shall not
               be unreasonably withheld,  unless such disclosure is required, on
               advice of  counsel,  in order to comply with  federal  securities
               laws or the listing  requirements  of NASDAQ or another  national
               stock exchange.

          10.11 Remedies Cumulative.  The  remedies  of the  parties  under this
               Agreement are cumulative and shall not exclude any other remedies
               to which any party may be lawfully entitled.

          10.1 Waiver. No  failure  or  delay  on  the  part  of any  party  in
               exercising any right,  power, or privilege hereunder or under any
               of the  documents  delivered in  connection  with this  Agreement
               shall operate as a waiver of such right, power, or privilege; nor
               shall any single or partial exercise of any such right, power, or
               privilege  preclude any other or further  exercise thereof or the
               exercise of any other right, power, or privilege.

          10.13 Further  Assurances. From time to time after the Closing, at the
               request of the Investors but without further  consideration,  the
               Company and the Stockholders  will execute and deliver such other
               instruments of conveyance, assignment, transfer, and delivery and
               take such other action as the Investors reasonably may request in
               order to consummate the transactions contemplated hereby.

          10.14 Headings. The descriptive  section  headings are for convenience
               of reference  only and shall not control or affect the meaning or
               construction of any provision of this Agreement.

EXHIBIT B

                                ESCROW AGREEMENT


                  THIS ESCROW AGREEMENT (this  "Agreement") dated this ----- day
of --------------,  1997, is entered into by and among GOLDER,  THOMA,  CRESSEY,
RAUNER FUND IV, L.P., a Delaware limited partnership ("GTCR"), and certain other
investors as are signatory  hereto  (collectively,  GTCR and the other investors
are referred to herein as the "Investors"),  -----------------------------------
(the  "Escrow  Agent"),  CAPITOL  OFFICE  SOLUTIONS,  INC.  (f/k/a  Capitol Copy
Products,  Inc.),  a Delaware  corporation  (the  "Company"),  CERBCO,  INC.,  a
Delaware corporation ("Cerbco"),  and CERBERONICS,  INC., a Delaware corporation
("Cerberonics;"  collectively,  Cerberonics and Cerbco are referred to herein as
the "Cerberonics Parties"), and ARMEN A. MANOOGIAN ("Manoogian")  (collectively,
the   Cerberonics   Parties  and   Manoogian  are  referred  to  herein  as  the
"Stockholders").


                                    Recitals

     A. The Company,  the  Investors and the  Stockholders  have entered into an
Investment,  Redemption and Stock Purchase  Agreement  dated as of February ---,
1997 (the "Investment and Redemption Agreement").

     B. Pursuant to the Investment and Redemption Agreement, (i) the Cerberonics
Parties  have  agreed  to sell to the  Company  and the  Company  has  agreed to
purchase from the  Cerberonics  Parties all the shares of the Company's  capital
stock held by Cerberonics (the "Redemption") in exchange for the price set forth
in Section 2.3 of the  Investment  and  Redemption  Agreement  (the  "Redemption
Price");  (ii) GTCR has agreed to purchase  from the Company and the Company has
agreed to sell to GTCR 49.5 shares of the Company's  Class A Common Stock and .5
shares of the  Company's  Class C Common  Stock  (the  "Investment");  and (iii)
Manoogian has agreed to sell to the  Investors and the Investors  have agreed to
purchase from Manoogian all of the shares of the Company's  Class A Common Stock
held by him and 62.5% of the  Company's  Class C Common  Stock  held by him (the
"Stock  Purchase")  in  exchange  for the price set forth in Section  2.5 of the
Investment and Redemption Agreement (the "Stock Purchase Price").

     C. This Escrow  Agreement  is entered  into for the purpose of securing and
providing a first,  but  non-exclusive  source for satisfying any amount that is
required to be paid by the Stockholders  jointly or separately to the Investors,
the Company  and/or any of the  Indemnified  Parties for the purposes and in the
manner  described  in  Section  2.7  and  Article  VIII  of the  Investment  and
Redemption Agreement.

     D.  Obligations  for amounts due to the  Investors,  the Company and/or any
Indemnified  Parties under the Investment  and Redemption  Agreement are in most
instances mutual to both the Cerberonics Parties and Manoogian,  however,  there
are  certain  limitations  on  the  Stockholders'   indemnification  obligations
provided for in Section 8.6 of the Investment and Redemption Agreement, and this
Agreement allocates certain  responsibilities  among the Cerberonics Parties and
Manoogian according to such limitations.


                                    Agreement

                  NOW, THEREFORE,  in consideration of the premises, the parties
do hereby agree as follows:

     a. Deposit of Cash and Securities.

               (a) Concurrent  with the closing  contemplated by Section 2.13 of
          the Investment and Redemption Agreement, the Company and the Investors
          shall cause to be deposited with the Escrow Agent,  in accordance with
          the following  sentence,  the sum of $1,500,000 (the "Escrow Sum") for
          the  purposes  intended  in  Section  2.7 and  Article  VIII  thereof.
          Pursuant to Section 2.7 of the Investment  and  Redemption  Agreement,
          (i) an amount  equal to  19/27ths  of the Escrow Sum shall be deducted
          from the  Redemption  Price and deposited with the Escrow Agent as the
          Cerberonics Parties' share of the Escrow Sum (i.e., $1,055,556)




                                        1

          (the "Cerbco Escrow  Account"),  and (ii) the following  shall be
          deposited with the Escrow Agent as Manoogian's share of the Escrow Sum
          (i.e., $444,444), (A) an amount of cash equal to 5/27ths of the Escrow
          Sum (i.e., $277,778),  which shall be deducted from the Stock Purchase
          Price  (the "Cash  Component")  and (B) 8.33  shares of the  Company's
          Class B Common Stock (which have a liquidation  value equal to 3/27ths
          of  the  Escrow  Sum  or  $166,667)   (the   "Securities   Component;"
          collectively, the amounts set forth in clauses (A) and (B) above shall
          be referred to herein as the "Manoogian Escrow  Account").  The Escrow
          Agent will keep accounting records which segregate the Escrow Sum into
          two separate  accounts,  the Cerbco  Escrow  Account and the Manoogian
          Escrow Account.

               (b) The Escrow Sum is to be retained by the Escrow Agent pursuant
          to this  Agreement,  and the  Escrow  Sum and  income  thereon  may be
          disbursed by the Escrow Agent only in accordance with this Agreement.

               (c) Manoogian will retain the right to vote the shares of Class B
          Common Stock deposited in the Securities Component.

     b. Investment of the Escrow Sum.

               (1) The  portion  of the Escrow  Sum which is  comprised  of cash
          shall be  invested  by the Escrow  Agent at the  direction  of all the
          Stockholders in:

                   (i) U.S. Treasury bills having maturities of 90 days or less
                       or

                  (ii) U.S. Government Securities having maturities of one yea
                       or less; or

                 (iii) Certificates  of Deposit  issued by a national  or state
                       bank  that is a member of the FDIC and has over $100
                       million of capital and surplus,  or commercial paper
                       having  a  maturity  of 120  days or less  and an 
                       A-1/P-1  or comparable rating; or

                  (iv) Other marketable debt securities at the joint written
                       direction of the Investors and the Stockholders; or

                   (v) A money  market  fund backed by the full
                       faith  and  credit  of  the  U.S.  Government
                       consisting  of securities  with a maturity of 90 days
                       or less,  and providing for funds  available on 24 hours
                       advance  notice except in the event the Federal Reserve
                       Bank is closed.

               (2)  Portions  of the Escrow Sum not so  invested  may be kept in
          cash pending such investment.  The portions of the Escrow Sum invested
          under  (i),  (ii) and (iii)  above or held as cash shall be valued for
          all purposes  under this Agreement at "face value." All other portions
          of the  Escrow  Sum  shall be valued as  mutually  agreed  upon by the
          Stockholders  and the  Investors  in writing at the time such  parties
          give their  consent  to the  investment.  All  assets  held under this
          Agreement shall be registered in the names of any nominees selected by
          the Escrow Agent.

     c. Duties of the Escrow Agent

               (1) The Escrow  Agent shall  receive,  hold and invest the Escrow
          Sum  pursuant to the terms of this  Agreement.  Except as  hereinafter
          provided,  on -----------,  1998 (the first anniversary of the Closing
          Date),  or as soon  thereafter  as  possible,  the Escrow  Agent shall
          deliver to the Stockholders, or to their order, all remaining portions
          of their  respective  escrow accounts then held by the Escrow Agent in
          excess of the amounts (if any) reserved  against  Claims (as such term
          is defined  pursuant to Section 3(b) hereof).  Pursuant to Section 8.6
          of the Investment and Redemption  Agreement,  not all  indemnification
          obligations  of the  Stockholders  under the Investment and Redemption
          Agreement are mutual.  Where the  indemnification  obligations  of the
          Cerberonics Parties and Manoogian are mutual (e.g., where both parties
          are required to indemnify  the Company or the  Investors,  as the case
          may be, as a result of a breach of a covenant or a representation  and
          warranty that the Stockholders collectively made), the payment of such
          Claims shall be allocated among the  Stockholders as follows:  (i) the
          Cerberonics  Parties shall be responsible for 19/27ths  (70.37037%) of
          such Claim and the Cerbco Escrow Account shall be adjusted accordingly
          and (ii) Manoogian




                                        2

<PAGE>



          shall be responsible  for 8/27ths  (29.62963%) of such Claim and,
          subject to Section 3(c) below,  the Manoogian  Escrow Account shall be
          adjusted   accordingly.   Where  Manoogian  has  sole  indemnification
          responsibility  for such Claim  (e.g.,  where  there was a breach of a
          given  representation  and  warranty but the  Cerberonics  Parties are
          found  to  be  excused  from  their   indemnification   obligation  in
          connection  therewith  because  they had no  actual  knowledge  of the
          matter  in  question,  as  per  Section  8.6  of  the  Investment  and
          Redemption   Agreement),   then  Manoogian   shall  be  solely  (100%)
          responsible  therefor,  and where the  Cerberonics  Parties  have sole
          indemnification responsibility for such Claim (e.g., where there was a
          breach of a given  representation  and warranty but Manoogian is found
          to be  excused  from  his  indemnification  obligation  in  connection
          therewith,  as  per  Section  8.6  of the  Investment  and  Redemption
          Agreement),  then  the  Cerberonics  Parties  shall be  solely  (100%)
          responsible   therefor.   (The  relevant   percentage   allocation  of
          responsibility  for a  Claim  (either  100%,  70.37037%  or 0% for the
          Cerberonics  Parties and either 100%,  29.62963% or 0% for  Manoogian)
          shall be referred  to herein as the  parties'  respective  "Percentage
          Interests.")

               (2) Upon  written  notice from the  Investors to the Escrow Agent
          and the  Stockholders  jointly or individually (in the event the claim
          is the sole  responsibility  of one  Stockholder) of any claim against
          the Escrow Sum under  Section 2.11 of the  Investment  and  Redemption
          Agreement  or under  Article  VIII of the  Investment  and  Redemption
          Agreement  against  the  Stockholders,   which  notice  sets  forth  a
          description  of the facts upon which the claim is based and the amount
          of the claim (a "Claim", with the notice thereof referred to herein as
          the "Claim  Notice"),  the Escrow Agent  immediately  shall reserve an
          amount in the  Escrow  Sum equal to the Claim  specified  in the Claim
          Notice  (the  "Reserved   Amount")  and  shall  make  the  appropriate
          allocations  to the Cerbco Escrow  Account or, subject to Section 3(c)
          below, the Manoogian Escrow Account;  provided,  however,  that if the
          Claim is based on an  indemnification  obligation  which is solely the
          responsibility of one Stockholder,  the Escrow Agent shall not reserve
          an amount  against the Escrow Sum in excess of the  current  unclaimed
          Escrow Sum allocable to such Stockholder's escrow account.

               (3) Any amounts required to be deducted from the Manoogian Escrow
          Account  in  order  to  satisfy  a  Claim  under  the  Investment  and
          Redemption  Agreement  shall be deducted first from the Cash Component
          until the Cash  Component  shall be reduced to zero, and then from the
          Securities Component.

               (4)  The  Investors   shall  notify  the  Escrow  Agent  and  the
          Stockholders  jointly or  individually  (in the event the Claim is the
          sole  responsibility  of one  Stockholder)  of a Claim by delivering a
          copy of the Claim  Notice to the  Escrow  Agent and both or one of the
          Stockholders,  as appropriate,  as provided in Section 6(f) hereof. In
          the event the  Stockholders  who are  potentially  responsible for the
          Claim do not notify the Escrow  Agent and the  Investors in writing of
          an objection  to the Claim within  fifteen (15) days of the mailing by
          the Investors of the Claim  Notice,  the Escrow Agent shall deliver to
          the Investors  from the Escrow Sum the Reserved  Amount and shall make
          all  necessary  adjustments  to the  Cerbco  Escrow  Account  and  the
          Manoogian Escrow Account.

               (5) In the event a Claim  Notice is received by the Escrow  Agent
          and the Escrow  Agent  receives a written  objection to the Claim from
          the  Stockholders  who are  potentially  responsible  therefor  within
          fifteen (15) days of the mailing by the Investors of the Claim Notice,
          the Escrow Agent shall continue to hold the Reserved  Amount  relating
          to that  Claim  Notice  until it either (i)  receives a joint  written
          direction  from the Investors and the  responsible  Stockholders  with
          respect to the  disposition of such Reserved  Amount of the Escrow Sum
          or (ii) until the  Investors  and the  responsible  Stockholders  have
          resolved the Claim.

               (6) Any  interest  or other  income  earned by the Cerbco  Escrow
          Account and the Manoogian Escrow Account, net of any transaction costs
          associated with investment  thereof,  shall be paid to the Cerberonics
          Parties  and  Manoogian,  respectively,  at the  termination  of  this
          Agreement to the extent not paid to the Company or the  Investors,  as
          the case may be, pursuant to a Claim Notice.

               (7)  The  Escrow  Agent  shall  provide  the  Investors  and  the
          Stockholders  with quarterly  reports of assets held and income earned
          by the  Escrow Sum  including  an  accounting  of amounts of the total
          Escrow Sum allocated to the Cerbco Escrow Account and to the Manoogian
          Escrow Account.

Notwithstanding  anything to the contrary above, it is the intent of the parties
that (i) with  respect to  payments  of the Escrow  Sum in  satisfaction  of the
Stockholders obligations under Section 2.11(a) of the Investment and




                                                         3

Redemption   Agreement,   such  payments  will  be  allocated  19/27ths  to  the
Cerberonics  Parties and 8/27ths to  Manoogian;  and (ii) with respect to Claims
that relate to the Stockholders'  indemnification obligations under Article VIII
of the  Investment  and Redemption  Agreement,  $444,444  (comprised of the Cash
Component and the Securities Component) of the original Escrow Sum shall be used
to fund  Claims made by the  Company or the  Investors,  as the case may be, for
which  Manoogian is responsible  and $1,055,556 of the original Escrow Sum shall
be used to fund  Claims  made by the  Investors  or the  Company  for  which the
Cerberonics Parties are responsible,  such that the Cerbco Escrow Account cannot
be used to fund  Claims  for  which  Manoogian  is solely  responsible,  and the
Manoogian Escrow Account cannot be used to fund Claims for which the Cerberonics
Parties is solely responsible.

     d. Resolution of Disputes. All disputes between the Stockholders (or either
of them) and the  Investors  with respect to (a) the Escrow Sum, (b) the payment
of Escrow  Sum  amounts  pursuant  to  Section 3 hereof,  (c) the  allowance  or
disallowance  of a Claim,  or (d) the terms of this  Agreement or the rights and
obligations of the  Stockholders  and the Investors  hereunder,  which cannot be
resolved promptly by mutual agreement,  will be resolved by binding  arbitration
in  accordance  with the rules of the American  Arbitration  Association  and in
accordance with the Arbitration Procedures attached hereto as Exhibit A.

     e. Operations.

        The Stockholders, the Company and the Investors hereby agree
        with the Escrow Agent that:

                    (1)   The   Escrow   Agent   shall   have   no   duties   or
               responsibilities   except  as  expressly  provided  for  in  this
               Agreement.

                    (2)  The  Escrow  Agent  shall  not be  responsible  for the
               identity,  authority or rights of any person, firm or corporation
               executing or  delivering or purporting to execute or deliver this
               Agreement or any document or security deposited  hereunder or any
               endorsement thereon or assignment thereof.

                    (3)  The  Escrow  Agent  shall  not be  responsible  for the
               sufficiency,  genuineness or validity of or title to any document
               or security deposited or to be deposited with it pursuant to this
               Agreement or of any endorsement thereon or assignment thereof.

                    (4) The Escrow Agent may rely upon any instrument or writing
               believed  by  it  to  be  genuine  and  sufficient  and  properly
               presented,  and shall not be liable or responsible for any action
               taken or omitted in accordance with the provisions thereof.

                    (5) The Escrow Agent shall not be liable or responsible  for
               any  act it may do or omit to do in the  exercise  of  reasonable
               care.

                    (6) In case any property held by the Escrow Agent  hereunder
               shall be  attached,  garnished  or levied upon under any order of
               any court or the delivery  thereof shall be stayed or enjoined by
               any order of any court,  or any other  order,  judgment or decree
               shall be made or entered by any court  affecting such property or
               any part  thereof  or any acts of the  Escrow  Agent,  the Escrow
               Agent is hereby authorized,  in its exclusive discretion, to obey
               and  comply  with all  writs,  orders,  judgments,  or decrees so
               entered or issued, whether with or without jurisdiction,  and, if
               the Escrow  Agent obeys and complies  with any such writ,  order,
               judgment or decree,  it shall not be liable to any of the parties
               hereto, their successors, heirs or personal representatives or to
               any  other  person,  firm  or  corporation,  by  reason  of  such
               compliance,  notwithstanding such writ, order, judgment or decree
               being subsequently  reversed,  modified,  annulled,  set aside or
               vacated.

                    (7)  The  Escrow  Agent  shall  be  entitled  to  reasonable
               compensation for its services and may employ agents and attorneys
               for the reasonable protection of the property held hereunder.

                    (8) The Investors,  the Company and the Stockholders jointly
               and  severally  agree to  indemnify  and hold  the  Escrow  Agent
               harmless  from  any  and all  costs,  expenses,  claims,  losses,
               liabilities and damages  (including  reasonable  attorneys' fees)
               that may arise out of or in  connection  with the Escrow  Agent's
               acting as Escrow Agent under the terms of this Escrow  Agreement,
               except in those  instances where the Escrow Agent has been guilty
               of gross negligence or willful misconduct.

     f. Miscellaneous.

                    (1) This  Agreement  shall be binding  upon and inure to the
               benefit of the parties hereto and their respective successors and
               permitted  assigns,  and no other  persons  shall have any rights
               herein. No transferee, successor or assign of the Stockholders or
               the Investors  shall have any rights  hereunder until each notice

               or succession is provided to Escrow Agent.

                    (2) This  Agreement  may be executed  and endorsed in one or
               more  counterparts and each of such  counterparts  shall, for all
               purposes, be deemed to be an original,  but all such counterparts
               shall together constitute one and the same instrument.

                    (3) All fees  and  expenses  of the  Escrow  Agent  shall be
               shared  equally  by the  Stockholders,  on the one hand,  and the
               Investors  on the other  hand,  except  that any  expenses of the
               Escrow Agent in connection with any litigation hereunder shall be
               paid by the party obligated for the cost of such litigation.

                    (4) A successor Escrow Agent may be appointed at any time by
               mutual agreement of the Stockholders and the Investors.

               Sum in two  segregated and separate  accounts,  the Cerbco Escrow
               Account and the Manoogian  Escrow  Account,  outside the reach of
               its general creditors.

                    (6) Any notice,  statement or other  communication  which is
               required to be given, including Claim Notices, hereunder shall be

EXHIBIT C

                                VOTING AGREEMENT


         THIS VOTING AGREEMENT (this  "Agreement")  dated as of March 7, 1997 is
by and among  Robert W.  Erikson  and  George  Wm.  Erikson  (collectively,  the
"Eriksons" or the  "Stockholders"),  CERBCO,  Inc., a Delaware  corporation (the
"Company"),  CERBERONICS,  Inc.,  a  Delaware  corporation  and  a  wholly-owned
subsidiary of the Company  ("Cerberonics"),  Capitol Office  Solutions,  Inc., a
Delaware corporation  ("Capitol"),  and Golder, Thoma, Cressey,  Rauner Fund IV,
L.P., a Delaware  limited  partnership  ("GTCR IV"),  on behalf of itself and as
agent for the other investors (collectively,  with GTCR IV, the "Investors") who
are  listed in  Schedule  1 to and are  signatory  to the  Redemption  Agreement
referenced in Recital B below.


                                    Recitals


     P.  The  Company,  through  Cerberonics,   owns  two-thirds  of  the  total
outstanding common stock of Capitol.  Armen A. Manoogian  ("Manoogian") owns the
remaining one-third of the outstanding common stock of Capitol.

     Q.  Concurrently  herewith,  the Company,  Cerberonics  and  Manoogian  are
entering  into an  Investment,  Redemption  and Stock  Purchase  Agreement  (the
"Redemption  Agreement")  with  Capitol,  GTCR IV and the other  Investors,  and
pursuant to which (i) the Investors are purchasing certain new shares of Capitol
common  stock  from  Capitol,  (ii) the  Investors  are  purchasing  certain  of
Manoogian's  shares of common  stock in Capitol,  and (iii) with the proceeds of
the purchase  referenced in clause (i) of this Recital B and certain  borrowings
to be made by Capitol,  Capitol is redeeming all of the shares of Capitol common
stock  owned  by  Cerberonics  (the  "Redemption").   (The  Redemption  and  the
transactions  described in clauses (i) and (ii) of this Recital B are  sometimes
collectively referred to herein as the "Transactions").

     R. Because the  shareholdings in Capitol  constitute a substantial asset of
the Company, the Company, Cerberonics, Capitol, Manoogian and the Investors deem
it advisable in order to effect the Transactions  that the Eriksons,  on the one
hand, and the Non-Erikson  stockholders of the Company,  on the other hand, each
be  provided  the  opportunity  to vote on the  sale of the  Company's  stake in
Capitol pursuant to the Redemption.  Accordingly, the Company's obligation under
the Redemption Agreement is effectively contingent upon, among other conditions,
the affirmative votes of (i) a majority of the votes cast by the stockholders of
the Company  other than the  Eriksons,  and (ii) a majority of the votes cast by
the Eriksons. In lieu of voting at a meeting of the stockholders of the Company,
approval of the  stockholders  of the  Company may be obtained by their  written
consents, equivalent in number to the required affirmative votes.

     S. As of the date  hereof,  the  Stockholders  own (a) 115,056  shares,  or
approximately  9.9% of the total  outstanding  Common  Stock of the Company (the
"Common  Stock") and (b) 245,318  shares,  or  approximately  78.9% of the total
outstanding Class B Common Stock of the Company (the "Class B Stock"), exclusive
of 2,246  shares of Common  Stock  and  2,246  shares of Class B Stock  owned by
George Wm. Erikson jointly with his spouse (the "GWE Joint Shares") (such shares
(again, exclusive of the GWE Joint Shares) and any other shares of the Company's
capital stock acquired by the  Stockholders  subsequent to the date hereof being
herein referred to collectively as the "Shares") and desire to (i) agree to vote
any and all Shares in favor of the Redemption (subject to the proxy described in
clause  (i) of  Section 2 and the  conditions  set forth in  Section 3) and (ii)
grant to GTCR IV an irrevocable proxy covering the Shares.

     T.  The  Investors  have  required  as a  condition  to  entering  into the
Redemption  Agreement that the Stockholders  enter into this Agreement,  and the
Company,  Cerberonics,  and Capitol desire that the Stockholders enter into this
Agreement. The Company,  Cerberonics,  Capitol and the Investors will enter into
the   Redemption   Agreement   in  part  in   reliance   on  the   Stockholders'
representations, warranties and agreements under this Agreement.

                                    Agreement




                                        1

<PAGE>




         In consideration  of the mutual  covenants and agreements  contained in
this  Agreement and other good and valuable  consideration,  and intending to be
legally bound hereby, it is agreed as follows:

         1. Agreement to Support Redemption.  The Stockholders agree, subject to
the terms and  conditions of Section 3, to vote any Shares held by them in favor
of the Redemption pursuant to the terms of Redemption Agreement. In addition, if
subsequent to the date hereof the  Stockholders  are entitled to vote the Shares
on any Designated  Matters (as defined in Section 2 below),  they shall take all
actions necessary to vote the Shares pursuant to instructions received from GTCR
IV.

         2. Limited Proxy With Respect to the Shares.  The  Stockholders  hereby
irrevocably  appoint  GTCR IV as their  attorney  and proxy,  with full power of
substitution, to vote or to express written consent or dissent in such manner as
such attorney and proxy or its substitute  shall, in its sole  discretion,  deem
proper, and otherwise act (including pursuant to any corporate action in writing
without a meeting)  with respect to all of the Shares which they are entitled to
vote at any meeting of  stockholders  (whether  annual or special and whether or
not an adjourned meeting) of the Company, or pursuant to a written consent taken
in  lieu  of  any  such  meeting  or  otherwise;  provided,  however,  that  the
Stockholders  grant a proxy  hereunder  limited to and only with  respect to the
following matters (the "Designated Matters"): (i) votes or consents with respect
to the  Redemption;  (ii)  votes or  consents  with  respect  to any  action  or
agreement  that  would  result in a breach of any  covenant,  representation  or
warranty  or any  other  obligation  or  agreement  of  the  Company  under  the
Redemption  Agreement;  (iii)  votes or consents  with  respect to any action or
agreement involving Capitol that would impede,  interfere with, delay,  postpone
or attempt to  discourage  the  Redemption,  including,  but not limited to, any
extraordinary   corporate   transaction  (other  than  as  contemplated  by  the
Redemption Agreement), such as a merger, other business combination, the sale of
material assets,  reorganization or liquidation  involving Capitol. This limited
proxy is irrevocable,  is coupled with an interest  sufficient in law to support
an irrevocable  proxy and is granted in consideration of and as an inducement to
cause Capitol and Investors to enter into the transactions  contemplated by this
Agreement and the Redemption Agreement.  With respect to the Designated Matters,
this limited proxy shall revoke any other proxy granted by  Stockholders  at any
time with  respect to the Shares and no  subsequent  proxies  will be given with
respect thereto by Stockholders.

         3.       Condition to the Stockholders' Obligations.

                  (a)  The  Stockholders'   obligations  under  this  Agreement,
including without  limitation Section 1 (with respect to their voting the Shares
in favor of the Redemption  pursuant to the Redemption  Agreement) and Section 2
(with respect to their granting a proxy to GTCR IV) are conditioned upon (i) the
Company's Board of Directors,  prior to the closing of the Redemption  Agreement
not having either (x) exercised its fiduciary duties and withdrawn,  modified or
amended  in  a  manner  adverse  to  Capitol  or  Investors,  its  approval  and
recommendation of the Redemption and the Redemption  Agreement,  or (y) approved
or  recommended  any  transaction  relating to the  acquisition  of Capitol or a
substantial  portion of its assets other than pursuant to the Redemption and the
Redemption  Agreement,  and (ii) the  Redemption  and the  Redemption  Agreement
having been approved by the  affirmative  vote of a majority of the votes of the
other holders of the Company's  capital stock (i.e.,  votes other than the votes
of  the  Stockholders),  that  vote  thereon  at  a  meeting  of  the  Company's
stockholders.

                  (b) The  obligations  of the  parties  to  perform  under this
Agreement upon its execution and  thereafter  shall be subject to the additional
condition that there shall be no  preliminary  or permanent  injunction or other
order issued by any court of competent  jurisdiction  in effect which  prohibits
(i) this  Agreement  or (ii)  the  Redemption.  The  Stockholders,  Capitol  and
Investors  agree not to seek any such  injunction  or order and agree  that they
will oppose and will seek the immediate lifting of any such injunction or order.

                  (c) The  representations,  warranties and agreements of Robert
W. Eriksons under this Agreement are qualified and conditioned upon the terms of
the  brokerage  margin  agreements  relating  to certain of his shares of Common
Stock identified in Schedule 3(c) attached hereto.

         4.       Representations and Warranties of the Stockholders.  The 
Stockholders represent and warrant to the Company, Cerberonics, Capitol and the
Investors as follows:





                                        2

<PAGE>



                  (a)  Ownership of Shares.  On the date hereof,  other than the
GWE Joint  Shares,  the Shares are all of the shares of Common Stock and Class B
Stock currently owned by the Stockholders beneficially and of record. Other than
pursuant to  outstanding  options  described in the Company's  most recent proxy
statement,  the  Stockholders  do not have any rights to acquire any  additional
shares of Common Stock or Class B Stock. The Stockholders currently have, and at
the closing of the Redemption will have, good, valid and marketable title to the
Shares,  free  and  clear of all  liens,  encumbrances,  restrictions,  options,
warrants,  rights  to  purchase  and  claims  of  every  kind  (other  than  the
encumbrances  created by this Agreement and the margin agreements  identified on
Schedule 3(c) hereto and other than  restrictions  on transfer under  applicable
Federal and State securities laws).

                  (b) Power;  Binding Agreement.  The Stockholders have the full
legal  right,  power  and  authority  to  enter  into  and  perform  all  of the
Stockholders'  obligations  under this Agreement.  The execution and delivery of
this Agreement by the Stockholders will not violate any other agreement to which
the  Stockholders  are  a  party  including,   without  limitation,  any  voting
agreement,  stockholders  agreement,  voting trust or proxy.  This Agreement has
been duly executed and delivered by the  Stockholders  and  constitutes a legal,
valid and binding agreement of the Stockholders,  enforceable in accordance with
its terms,  except as the  enforcement  thereof  may be  limited by  bankruptcy,
insolvency,  reorganization,  moratorium  and similar laws,  now or hereafter in
effect affecting  creditors' rights and remedies generally or general principles
of  equity.  Neither  the  execution  or  delivery  of  this  Agreement  nor the
consummation by the  Stockholders of the transactions  contemplated  hereby will
(i) except as disclosed  on Schedule  4(b) require any consent or approval of or
filing with any  governmental or other  regulatory body except for filings under
the Securities  Exchange Act of 1934, as amended, or (ii) constitute a violation
of,  conflict with or  constitute a default  under,  any  contract,  commitment,
agreement, understanding,  arrangement or other restriction of any kind to which
the Stockholders are a party or by which either Stockholder is bound.

         5. Termination.  This Agreement (other than the provisions  relating to
expenses and indemnification  (Section 6) and confidentiality (Section 7)) shall
terminate on the earliest of the following to occur:

     (a)  the  date  on  which  the  Company,  Capitol,  the  Investors  and the
     Stockholders mutually consent to terminate this Agreement in writing;

     (b) the date of consummation  of the Redemption  pursuant to the Redemption
     Agreement;

     (c) prior to the successful consummation of the Redemption, the termination
     of the Redemption Agreement pursuant to its terms;

     (d) prior to the successful consummation of the Redemption, the withdrawal,
     modification or amendment by the Company's Board of Directors,  in a manner
     adverse to Capitol and the Investors, of its approval and recommendation of
     the Redemption and the Redemption Agreement;

     (e) prior to the successful consummation of the Redemption, the approval or
     recommendation  by the  Company's  Board of  Directors  of any  transaction
     relating  to the  acquisition  of  Capitol  or its  assets  other  than  in
     connection with the Redemption Agreement;

     (f) the  Redemption  and the  Redemption  Agreement  shall  not  have  been
     approved  by the  affirmative  vote of a majority  of the votes cast by the
     holders of the Company's capital stock other than the Stockholders; or

     (g) September 30, 1997.

         6. Expenses; Indemnification.

     (a) Expenses.  Subject to paragraph  (b) below,  each party hereto will pay
     all of its expenses in connection  with the  transactions  contemplated  by
     this Agreement, including, without limitation, the fees and expenses of its
     counsel and other advisers.





                                        3

<PAGE>



     (b) Indemnification.  To the extent the Company's directors (other than the
     Stockholders) in the proper exercise of their fiduciary  obligations to the
     Company  were   permitted  by  law  to  have  the  Company   indemnify  the
     Stockholders in their capacity as  stockholders,  the Company agrees to pay
     promptly and to indemnify the Stockholders and hold them harmless from, all
     reasonable expenses (including  attorneys fees and other professional fees)
     and loss  reasonably  incurred by the  Stockholders  in whole or in part in
     their capacity as stockholders in connection with the following:

                           (i)      The review and negotiation of this Agreement
         and research on related issues.

                           (ii)   Any   actual   or    threatened    litigation,
         investigation  or proceeding  initiated by another  stockholder  of the
         Company  relating to this  Agreement,  the  redemption,  the Redemption
         Agreement,  or the Erikson  Consulting  and  Non-Competition  Agreement
         (collectively,  the  "Agreements").  In no event,  however,  shall such
         expenses  or losses  include  any  expense or loss  arising  out of the
         failure by the Stockholders to perform their  obligations  under any of
         the Agreements.

                           (iii)   Any   actual   or   threatened    litigation,
         investigation or proceeding  initiated by one or more of the parties to
         this  Agreement  involving  a dispute as to the  interpretation  of the
         language  of this  Agreement,  or as to the  existence,  non-existence,
         occurrence  or   non-occurrence   of  any  of  the  conditions  to  the
         Stockholders'  obligations  under this Agreement set forth in Section 3
         hereof and any  dispute as to whether  this  Agreement  has  terminated
         under Section 5 hereof.  In no event,  however,  shall such expenses or
         losses  include  any  expense  or  loss  arising  from  an  intentional
         violation  of any of the  covenants  of the  Stockholders  set forth in
         Section 8.1 hereof.

                           (iv)   Any   actual   or    threatened    litigation,
         investigation  or  proceeding  initiated  by any other person or entity
         (including any government agency) other than another stockholder of the
         Company or one or more of the parties to this Agreement relating to any
         of the Agreements, provided that the Stockholders are successful on the
         merits or to the extent they otherwise prevail.  In no event,  however,
         shall such  expenses or losses  include any expense or loss arising out
         of the failure by the Stockholders to perform their  obligations  under
         any of the Agreements.

         The rights granted to the Stockholders under this Section 6(b) shall be
in addition to and not in lieu of any other rights.

         The  Stockholders  agree,  jointly  and  severally,  that they will pay
promptly and  indemnify the Company's  other  directors,  but only to the extent
they are not otherwise  indemnified by the Company or from  insurance,  from all
reasonable expenses  (including  attorneys fees and other professional fees) and
loss reasonably  incurred by either of those directors  arising from the Company
entering into this Agreement to indemnify the Stockholders.

         In the event of a dispute under this Section 6(b) either the Company or
one or both of the  Stockholders  may initiate  Alternative  Dispute  Resolution
("ADR"). ADR shall be pursuant to the provisions of 6. Del. C. ss.ss.  7701-7721
(the "Delaware ADR Act") expect that, as permitted by 6 Del. C. ss. 7702(a), the
parties  adopt by written  agreement a method of ADR that modifies the procedure
in the Delaware ADR Act as follows:

                           (i)  ADR  shall  apply  to  all  disputes,  including
         disputes  involving  $1,000 or more in contention and disputes over the
         interpretation of this paragraph 6(b).

                           (ii)     Once the Company or one or both of the 
         Stockholders elects ADR, the ADR proceedings may not be revoked.

                           (iii) If at the regular  close of business on the day
         the  mediation  hearing  commenced,  the parties  have not resolved the
         dispute,  the ADR  Specialist  at that time or within two (2)  business
         days thereof shall make a binding  non-appealable  determination of the
         dispute.

                           (iv) Each party  involved  in the  dispute  shall pay
         their  own  attorneys'  fees and an  equal  share of the fee of the ADR
         Specialist,  provided,  however,  if the ADR Specialist makes a binding
         non-appealable  determination of the dispute,  the ADR Specialist shall
         include in the determination the




                                        4

         allocation  of  payment  among  the  parties  of all fees and  expenses
         involved in the ADR  proceedings,  including  the fees and  expenses of
         both the ADR  Specialist  and the  parties'  attorneys.  Unless the ADR
         Specialist  deems  circumstances  mandate a different  allocation,  the
         losing  party  shall pay to the wining  party the amount of the winning
         party's  attorneys'  fees and expenses that do not exceed the amount of
         the losing party's fees and expenses,  as well as the fees and expenses
         of the ADR Specialist.

         7.   Confidentiality.   The  Stockholders   recognize  that  successful
consummation  of  the  transactions  contemplated  by  this  Agreement  and  the
Redemption Agreement may be dependent upon confidentiality with respect to these
matters.  Although the Company has not executed a Confidentiality Agreement with
respect  to the  transactions  contemplated  by the  Redemption  Agreement,  the
Stockholders  agree  that,  pending  public  disclosure  by  the  Company,   the
Stockholders  will not disclose or discuss these matters with anyone (other than
their legal counsel and advisors or the Company's legal counsel and advisors, if
any) not a party to this  Agreement  or the  Redemption  Agreement,  without the
prior written consent of Capitol and the Investors,  except for filings required
pursuant to the Securities  Exchange Act of 1934, as amended,  and the rules and
regulations  thereunder or disclosures the Company's or the Stockholders'  legal
counsel  advises in writing are  necessary in order to fulfill the  Company's or
the Stockholder's  obligations  imposed by law, in which events the Stockholders
shall give prompt prior notice of such disclosure to Capitol and Investors.

         8.       Certain Covenants of the Stockholders.

                  8.1 No Shop.  Except  (i) for  brokerage  margin  requirements
identified  in Schedule A and (ii) in  accordance  with the  provisions  of this
Agreement,  the Stockholders  agree,  while this Agreement is in effect, not to,

         Company is permitted to  participate  under the  Redemption  Agreement)
         with,  or  furnish  any  information  to, or afford  any  access to the
         properties,  books or records of the Company or Capitol,  or  otherwise
         assist,  facilitate  or  encourage,  any person or entity  (other  than
         Capitol and Investors, or their officers,  directors,  representatives,
         agents,  affiliates or associates)  in connection  with any possible or

         12.  Assigns.  This  Agreement  shall be binding  upon and inure to the
benefit of the parties hereto and their respective  successors and assigns,  but
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned by any of the parties hereto without the prior written consent
of the other parties.

         13.  Governing Law.  This Agreement, and all matters relating hereto, 
shall be governed by, and construed in accordance with the laws of the State of
Delaware without giving effect to the principles of conflicts of laws thereof.

         14. Injunctive  Relief. The parties agree that in the event of a breach
of any  provision  of this  Agreement,  the  aggrieved  party may be  without an
adequate  remedy at law.  The  parties  therefore  agree  that in the event of a
breach of any  provision of this  Agreement,  the  aggrieved  party may elect to
institute and prosecute  proceedings in any court of competent  jurisdiction  to
enforce  specific  performance  or to  enjoin  the  continuing  breach  of  such
provision,  as well as to obtain  damages for breach of this  Agreement and such
aggrieved  party may take any such  actions  without the  necessity of posting a

executed in any number of  counterparts,  each of which shall be deemed to be an
original and all of which together  shall  constitute one and the same document.
The  signature  of a  party  that  is sent to the  other  parties  by  facsimile
transmission  shall be binding as evidence of such  signatory's  agreement to be
bound by the terms of this Agreement.

         16.  Severability.  Any term or  provision of this  Agreement  which is
invalid or unenforceable in any jurisdiction shall, as to such jurisdiction,  be
ineffective  to the  extent  of  such  invalidity  or  unenforceability  without
rendering  invalid or  unenforceable  the remaining terms and provisions of this
Agreement or affecting  the  validity or  enforceability  of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable such provision shall be interpreted
to be only so broad as is enforceable.

         17. Further Assurances.  Each party hereto shall execute and deliver 
such additional documents as may be reasonably necessary to consummate the 
transactions contemplated by this Agreement.

         18. Third Party Beneficiaries.  Nothing in this Agreement, expressed 
or implied, shall be construed to give any person other than the parties hereto 
any legal or equitable right, remedy or claim under or by reason of this 
Agreement or any provision contained herein.

EXHIBIT D

                               ERIKSON CONSULTING
                          AND NON-COMPETITION AGREEMENT


     THIS AGREEMENT,  dated as of -----------,  1997, is between Capitol Office
     Solutions,  Inc.,  a Delaware  corporation  (the  "Company"),  and --------
     Erikson (the "Consultant").


                                    Recitals

     1.  Pursuant to that  certain  Investment,  Redemption  and Stock  Purchase
Agreement  dated  February ---, 1997 between the Company,  the  Company's  prior
stockholders  and certain  investors (the "Redemption  Agreement"),  a change of
control of the  Company  occurred in  connection  with the  consummation  of the
transactions  contemplated  by the  Redemption  Agreement  (defined  therein and
herein as the  "Transactions"),  effective  as of the  Closing  Date (as defined
thereunder).

     2. Prior to the Closing Date, the Consultant was a major stockholder of the
Company's  ultimate parent and a long-standing  member of the board of directors
of the Company,  and in such capacity gained valuable insight into the operation
of the Company's business and the copier supply and service industry  generally,
which  insight  and  expertise  would be useful and  valuable  to the  Company's
competitors.

     3. Immediately  following the closing of the Transactions and the change of
control  effected by the  Transactions,  the  Company,  with the approval of its
newly reconstituted board of directors,  now desires to engage the Consultant as
a  consultant  with  respect  to the  Company  and,  in  addition,  to  secure a
non-competition agreement from the Consultant,  and the Consultant is willing to
enter into such arrangements, all pursuant to the terms of this Agreement.

     4. The terms of the Redemption  Agreement and all of the  Transactions  and
this  Agreement and all other  related  agreements  between the parties  thereto
and/or their affiliates have been disclosed to the stockholders of CERBCO,  Inc.
("Cerbco") in a proxy statement relating thereto,  and the Redemption  Agreement
has been approved by Cerbco's stockholders.


                                    Agreement

     In consideration of the mutual agreements and premises herein contain,  the
receipt and  sufficiency  of which is hereby  acknowledged,  the Company and the
Consultant agree as follows:

     1.  Consulting.  The Company  hereby  engages the Consultant to serve as an
advisor and consultant  with respect to the Company,  and the Consultant  hereby
accepts such engagement, on the terms and conditions of this Agreement.

     2. Term of Engagement.  The term of the Consultant's  engagement  hereunder
shall  commence as of the date first written  above,  which shall be the Closing
Date under the Redemption Agreement, and shall continue thereafter for a term of
three (3) years until ----------------,  2000. In addition to any other remedies
the Company may have, the Company may terminate  this  Agreement  immediately in
the event of any  material  breach of the  provisions  of this  Agreement by the
Consultant that is not cured within 30 days.

     3. Duties.  In  consideration  for the  Consulting  Fee  (defined  below in
Section 8) to be paid to the Consultant as  compensation  hereunder,  during the
term  of this  Agreement,  the  Consultant  shall  at all  reasonable  times  be
available to the Company on a mutually agreeable,




                                        1

"as  needed"  basis to serve  as an  advisor  and  consultant  to the  Company's
management  and/or board of directors in  connection  with the  operation of the
Company's  business  (the  "Consulting  Services").   The  Consultant  shall  be
available  at least one (1) and up to a maximum  of three (3) days per month for
Consulting Services,  upon request of the Company. The Consulting Services shall
be scheduled and  performed in a manner that will not detract from  Consultant's
performance  of  his  duties  as a  director  and  officer  of  Cerbco  and  its
subsidiaries.

     4.  Expenses.  The Company will reimburse the Consultant for all reasonable
business  expenses  incurred by the Consultant in rendering  services  hereunder
upon  submission to the Company of an  accounting  and  substantiation  for such
expenses and related receipts.


     5.  Trade  Secret  Information.   The  Consultant   acknowledges  that  the
information,  observations  and  data  obtained  by  him  while  engaged  by the
Company's  parent  and/or while a member of the  Company's  board of  directors,
concerning the business or affairs of the Company or any of its Subsidiaries (or
any of their predecessors) and the copier supply and service industry, which the
Company  or any  such  Subsidiary  considers  to be  confidential  and  which is
proprietary to the Company or any such Subsidiary  ("Trade Secret  Information")
are  the  property  of  the  Company  or any  such  Subsidiary.  Therefore,  the
Consultant agrees that he shall not disclose to any unauthorized  Person (except
(i) to the Company or, at the request of the Company, its Affiliates (as defined
in the  Redemption  Agreement),  (ii) to any entity  which shall  succeed to the
business of the Company or any such Subsidiary,  (iii) as may be required in the
regular  course of  business of the  Company or any such  Subsidiary  or (iv) as
required  by  law) or use for his own  purposes  any  Trade  Secret  Information
without the prior written consent of the Company,  unless and to the extent that
the  aforementioned  matters become  generally known to and available for use by
the public or Persons  knowledgeable  in the Company's  industry other than as a
result of the  Consultant's  acts or omissions which constitute a breach hereof.
The Consultant shall deliver to the Company at the termination of the Agreement,
or at any other time the Company  may  request,  all  memoranda,  notes,  plans,
records, reports, computer tapes, printouts and software and other documents and
data (and copies thereof) relating to the Trade Secret Information, Work Product
(as  defined  below in Section  7) or the  business  of the  Company or any such
Subsidiary which he may then possess or have under his control.

     6.  Intellectual  Property.  The Consultant  acknowledges  that any and all
intellectual  property other than the Trade Secret  Information  (including,  if
any, all inventions, innovations, improvements,  developments, methods, designs,
analyses,  drawings,  reports and all similar or related information (whether or
not patentable))  which (i) relate to the Company's or any of its  Subsidiaries'
(or any of their  predecessors)  actual or  anticipated  business,  research and
development  or existing or future  products or services or (ii) result from any
work performed by the Consultant for the Company and its Subsidiaries (or any of
their predecessors) and which are conceived, developed or made by the Consultant
while  engaged by the  Company  ("Work  Product")  belong to the Company or such
Subsidiaries.

     7. Non-Compete, Non-Solicitation.

     (a) As further  consideration  for the Non- Compete Fee  (defined  below in
Section  8) to be paid  to the  Consultant  hereunder  and  his  exposure  to or
involvement in the Trade Secret Information, the Consultant acknowledges that in
the course of his  engagement  by the  Company,  he shall become  familiar  with
business data, trade secrets and other Trade Secret  Information  concerning the
Company and its  Subsidiaries  and that his  services  have been and shall be of
special,  unique and  extraordinary  value to the Company and its  Subsidiaries.
Therefore, the Consultant agrees that, during the Non-compete Period (as defined
in Section 10 hereof),  he shall not directly or indirectly own any interest in,
manage,  control,  participate in, consult with,  render services for, or in any
manner  engage in any business  competing  with the business the Company and its
Subsidiaries,  or their successors and assigns, were engaged in at the time this
Agreement was entered into within any countries or geographical regions in which
the Company and its  Subsidiaries,  or their  successors and assigns,  engage or
plan  to  engage  in  such  business  on  the  date  of the  termination  of the
Consultant's  engagement;  provided,  however, nothing herein shall prohibit the
Consultant  from  being a passive  owner of not more than 5% of the  outstanding
stock of any class of a  corporation  which is publicly  traded,  so long as the
Consultant has no active participation in the business of such corporation.

     (b) During the  Noncompete  Period,  the  Consultant  shall not directly or
indirectly  through  another entity (i) induce or attempt to induce any employee
of the Company or any of its  Subsidiaries to leave the employ of the Company or
such  Subsidiaries,  or in any way interfere with the  relationship  between the
Company  or any of its  Subsidiaries  and any  employee  thereof,  (ii) hire any
person who was a management  employee of the Company or any of its  Subsidiaries
at any time during the one-year period prior to the termination of the Agreement
or (iii) induce or attempt to induce any customer, supplier, licensee, licensor,
franchisee or other business  relation of the Company or any of its Subsidiaries
to cease doing  business  with the Company or such  Subsidiaries,  or in any way
materially interfere with the relationship between any such customer,  supplier,
licensee  or  business  relation  and  the  Company  or any of its  Subsidiaries
(including, without limitation, making any negative statements or communications
about the Company or its Subsidiaries).

     (c) If, at the time of  enforcement  of this  Section 8, a court shall hold
that the duration,  scope or area  restrictions  stated herein are  unreasonable
under circumstances then existing,  the parties agree that the maximum duration,
scope or area reasonable under such  circumstances  shall be substituted for the
stated duration, scope or area and that the court shall be allowed to revise the
restrictions  contained  herein  to cover  the  maximum  period,  scope and area
permitted by law. The Consultant agrees that the restrictions  contained in this
Section 8 are reasonable.

     (d) In the event of any breach or  threatened  breach by the  Consultant of
any of the  provisions of this Section 8, the Company and its  Subsidiaries,  in
addition and  supplementary to other rights and remedies  existing in its favor,
may apply to any court of competent jurisdiction for specific performance and/or
injunctive or other relief in order to enforce or prevent any  violations of the
provisions  hereof (without posting a bond or other security).  In addition,  in
the event of an alleged breach or violation by the Consultant of this Section 8,
the  Noncompete  Period shall be tolled until such breach or violation  has been
duly cured.

     (e)  Subject to the  foregoing,  nothing in this  Agreement  shall  prevent
Consultant  from accepting any employment or consulting  engagements of any kind
or from otherwise accepting any business opportunity.

     8. Compensation. For the Consultant's agreements contained in Sections 5, 6
and 7 hereof,  the  Company  shall pay the  Consultant  a fee of  $150,000  (the
"Noncompete Fee") which shall be due and payable promptly after the date hereof.
For providing the Consulting  Services during the term hereof, the Company shall
pay  Consultant  a total fee of $150,0000  (the  "Consulting  Fee").  Unless the
Company and the Consultant  mutually agree to a different  installment  schedule
(e.g., monthly or quarterly), the Fee shall be paid in three annual installments
of $50,000 each.  The first payment shall be due and payable  promptly after the
date hereof, with respect to the Consultant's first year of Consulting Services.
The second  payment  shall be due and payable on the first  anniversary  of such
date, with respect to the Consultant's second year of Consulting  Services.  The
third  payment shall be due and payable on the second  anniversary  of such date
with respect to the third year of such Consulting Services. Any payment due on a
day which is not a business day shall be paid on the next business day.  Accrued
but unpaid  Fees shall bear  interest  at the rate of [eight  percent  (8%)] per
annum until paid. If at the time payment of the second or third  installment  is
due, the Consultant is unavailable or unable to perform  Consulting  Services in
that year, the Company shall not be required to make the applicable payments.

     9.  Consultant's  Representations.  The  Consultant  hereby  represents and
warrants to the Company that (i) the execution,  delivery and performance by the
Consultant of this  Agreement and all other  agreements  contemplated  hereby to
which the  Consultant  is a party do not and shall not  conflict  with,  breach,

                         Specialist  shall be as agreed  upon by the parties or,
                         absent  such  agreement,   split  equally  between  the
                         parties.

                    (iv) If at the  regular  close  of  business  on the day ADR
                         commenced,  the parties  have not resolved the dispute,
                         the ADR  Specialist  at that  time  or  within  two (2)
                         business    days   thereof   shall   make   a   binding

                         expenses  and  fees  of the ADR  Specialist  and of the
                         prevailing  party shall be paid by the losing party, as

                         stockholders   of  the   Company   (the   "Stockholders
                         Agreement").

                         to physical or mental illness such that he is unable to
                         perform his previously  assigned  duties where (A) such
                         incapacity  has been  determined to exist by either (i)
                         the Company's  disability  insurance carrier or (ii) by

     Executive  must be notified in writing  (which  writing  shall  specify the
     cause in reasonable detail) of any termination of his employment for Cause.
     Executive  will then have the  right,  within  ten days of  receipt of such
     notice, to file a written request for review by the Company.  In such case,
     Executive  will be given  the  opportunity  to be heard,  personally  or by
     counsel,  by the Board and a  majority  of the  Directors  must  thereafter
     confirm that such termination is for Cause. If the Directors do not provide
     such  confirmation,  the  termination  shall be  treated  as other than for
     Cause.

     The delivery by the Company of notice to Executive  that it does not intend
     to renew this  Agreement  as  provided in Section  1.6 shall  constitute  a
     termination  by the Company  without Cause unless such notice  fulfills the
     requirements of Section 1.5(a)(v)(A), (B), (C) or (D) above.

                    (vi) Executive's  voluntary  resignation  by the delivery to
                         the  Board of a  written  notice  from  Executive  that
                         Executive  has  resigned  with or without  Good Reason.
                         "Good Reason" shall mean  Executive's  resignation from
                         employment  with the  Company  within 30 days after the
                         occurrence of any one of the following:

                                            (A) the  failure  of the  Company to
                           pay an  amount  owing to  Executive  hereunder  after
                           Executive  has  provided  the  Company  with  written
                           notice  of such  failure  and  such  payment  has not
                           thereafter  been made within 15 days of the  delivery
                           of such written notice;

                                            (B)  the forced relocation of 
                           Executive from the Washington, D.C.
                           metropolitan area without his consent; or

                                            (C)   a   material    reduction   in
                           Executive's  title or duties  from those set forth in
                           this  Agreement  without  Executive's  prior  written
                           consent.

     (b) Rights on Termination.

                    (i)  In the event that termination is by Executive with Good
                         Reason or by the  Company  without  Cause,  the Company
                         will pay  Executive  the Base Salary for a period equal
                         to one year.

                    (ii) In the  event  termination  is by the  Company  without
                         Cause and the Company is meeting 100% of its  operating
                         income  (EBIT) budget (as such budget shall be mutually
                         agreed upon by Executive  and Golder,  Thoma,  Cressey,
                         Rauner  Fund  IV,  L.P.,   and  as  set  forth  in  the
                         then-current   Annual  Plan  approved  by  the  Board),
                         Executive  shall  have the right to  proceed  under the
                         provisions  relating  to the  sale  of the  Company  as
                         contemplated  by  Section  6(b)  of  the   Stockholders
                         Agreement and the Company shall  continue to employ the
                         Executive,  and  the  Executive  agrees  that  he  will
                         continue to serve, as the Company's President and Chief
                         Executive  Officer until, and the effective date of his
                         termination  shall  be,  the  date on  which  any  sale
                         pursuant to such Section 6(b) is consummated.

                    (iii)If the Company  terminates  Executive's  employment for
                         Cause,  if Executive dies or is disabled,  if Executive
                         resigns  without  Good Reason or in the event of a sale
                         of the Company as  contemplated  by Section 6(b) of the
                         Stockholders  Agreement,  the Company's  obligations to
                         pay any  compensation  or benefits under this Agreement
                         will cease effective  




                                        3

<PAGE>



                         the  date of  termination.  Executive's  right to
                         receive any other benefits will be determined under the
                         provisions   applicable   plans,   programs   or  other
                         coverages.

     Notwithstanding  the foregoing,  the Company's  obligation to Executive for
severance pay or other rights under either  subparagraphs (i) or (ii) above (the
"Severance  Pay") shall cease if Executive is in violation of the  provisions of
Section 1.7(a)  hereof.  The Severance Pay, if any, shall be paid by the Company
to Executive in equal monthly consecutive installments payable commencing on the
Company's   regularly   scheduled  payroll  date  next  following  the  date  of
Executive's  termination.  Until such time as Executive  has received all of his
Severance  Pay, he will be  entitled  to  continue to receive any health,  life,
accident and disability  insurance benefits provided by the Company to Executive
under  this  Agreement.  If  Executive  dies or is  permanently  disabled,  then
Executive  or his estate  shall be  entitled  to any  disability  income or life
insurance payments from any insurance policies paid for by the Company.

     1.6 Term of Employment.  Unless Executive's employment under this Agreement
is sooner  terminated as a result of  Executive's  resignation or termination in
accordance  with the provisions of Section 1.5(a) above or a sale of the Company
as  contemplated  by Section  6(b) of the  Stockholders  Agreement,  Executive's
employment  under this  Agreement  shall  commence  on the date hereof and shall
terminate  on the third  anniversary  of the date hereof (the  "Service  Term");
provided,  however,  that Executive's  employment under this Agreement,  and the
Service Term, shall be automatically  renewed for one-year periods commencing on
the third  anniversary of the date hereof and,  thereafter,  on each  successive
anniversary  of such date unless  either the Company or  Executive  notifies the
other party in writing within thirty days prior to any such  anniversary that it
or he desires to terminate Executive's employment under this Agreement.

     1.7 Covenant Not to Compete.

     (a)  Executive  agrees that,  during the Service Term and for a period (the
     "Noncompete Period") ending two years after Executive ceases to be employed
     by the Company, he will not, except with the express written consent of the
     Board,  either  directly  or  indirectly,  for  himself  or on behalf or in
     conjunction  with  any  other  person,  partnership,  corporation  or other
     entity, own, maintain, engage in, render any services for, manage, have any
     financial interest in, or permit his name to be used in connection with any
     office  equipment/copier  service or dealer  business  in any market in the
     United States in which the Company or its  subsidiaries are engaged or have
     firm  plans to enter  within  six  months  after the date that  Executive's
     employment hereunder is terminated; provided, however, that notwithstanding
     the foregoing such covenant shall not apply to Executive's  ownership of up
     to 5% of the outstanding  voting  securities of any  publicly-held  company
     which may be  engaged  in the  office  equipment/copier  service  or dealer
     business.

     (b) If, at the time of  enforcement  of any  provision  of  Section  1.7(a)
     above, a court holds that the restrictions  stated therein are unreasonable
     under  circumstances  then  existing,  the  parties  hereto  agree that the
     maximum  period,   scope  or  geographical   area  reasonable   under  such
     circumstances will be substituted for the stated period, scope or area.

     (c) In the event of a breach by  Executive  of the  provisions  of  Section
     1.7(a) above,  the Company or its successors or assigns may, in addition to
     other  rights and remedies  existing in their favor,  apply to any court of
     competent  jurisdiction for specific performance and/or injunctive or other
     relief in order to enforce  or prevent  any  violations  of the  provisions
     thereof.

     (d) After the later of (i) the date  Executive's  employment  hereunder  is
     terminated (whether due to his termination or resignation) or (ii) the date
     that  Executive  has  received  all of his  Severance  Pay (such date being
     referred to as the "Effective Date"), the Company shall advise Executive of
     its election to continue to enforce the  provisions of Section 1.7(a) above
     for the period of time desired,  in  incremental  periods of one month,  in
     writing  within 15 business days after the  Effective  Date. If the Company
     elects to continue to enforce the  provisions  of Section  1.7(a) after the
     Effective   Date,   the  Company   shall  pay   Executive,   as  additional
     consideration for Executive's  agreement not to compete, an amount equal to
     15% of  Executive's  then  monthly  Base  Salary  during  each month of the
     non-compete commencing with the first calendar month after the month of the
     Effective  Date, such amount to be paid to Executive in accordance with the
     Company's  normal  payroll  schedule.  In no event  shall such time  period
     exceed the Noncompete Period set forth in Section 1.7(a) above.

     (f)  The  provisions  of this  Section  1.7 are  independent  of any  other
     noncompete  agreement  between  the  Company  and  Executive  and  shall be
     cumulative with any such noncompete provisions set forth in such agreement.

     1.8 Confidential  Information.  Executive acknowledges that the information
and data  obtained by him during the course of his  employment  with the Company
concerning  the  business or affairs of the Company and its  affiliates  are the
property of the Company.  Therefore,  Executive agrees that he will not disclose
to any unauthorized person or use for his own benefit any of such information or
data without the Board's  prior written  consent,  unless and to the extent that
the  aforementioned  matters become  generally known to and available for use by
the  public  otherwise  than as a  result  of  Executive's  acts  or  omissions.
Executive agrees to deliver to the Company at the termination of his employment,
or at any other time the Company  may  request,  all  memoranda,  notes,  plans,
records,  reports  and other  documents  (and  copies  thereof)  relating to the
business  of the Company and its  Affiliates  which he may then  possess or have
under his control.

     1.9  Executive's  Representations  and Warranty.  Executive  represents and
warrants that he has full right and  authority to enter into this  Agreement and
fully to  perform  his  obligations  hereunder,  that he is not  subject  to any
non-competition  agreement,  and that his past,  present and anticipated  future
activities have not and will not infringe on the  proprietary  rights of others.
Executive  further  represents  and warrants that he is not obligated  under any
contract (including  licenses,  covenants or commitments of any nature) or other
agreement,  or  subject  to any  judgment,  decree  or  order  of any  court  or
administrative  agency which would  conflict with his obligation to use his best
efforts to promote the interests of the Company or which would conflict with the
Company's  business  as  conducted  or  proposed  to be  conducted.  Neither the
execution nor delivery of this  Agreement,  nor the carrying on of the Company's
business as an officer, director or employee by Executive, will conflict with or
result in a breach of the terms,  conditions  or  provisions  of or constitute a
default under any contract,  covenant or instrument under which Executive is now
obligated.

Board of Directors
CERBCO, Inc.
3421 Pennsy Drive
Landover, Maryland 20785

Gentlemen:

Capitol Office Solutions, Inc., a Delaware Corporation ("Capitol"), Cerberonics,
Inc., a Delaware Corporation  ("Cerberonics"),  and a wholly-owned subsidiary of
CERBCO,  Inc., a Delaware  Corporation  ("CERBCO"),  CERBCO and Armen Manoogian,
President and minority shareholder of Capitol,  have entered into an Investment,
Redemption and Stock Purchase  Agreement (the "Agreement")  with Golder,  Thoma,
Cressey,  Rauner Fund IV dated as of March 7, 1997.  Pursuant to the  Agreement,
the parties  thereto will enter into several  contemporaneous  transactions as a
result of which,  among other things,  Capitol will redeem all shares of Class A
common  stock,  Class B common stock and Class C common stock of Capitol held by
Cerberonics immediately prior to the closing of the transactions contemplated by
the Agreement (the "Transaction") for $19 million in cash (the "Consideration").
The Transaction is more fully described in the Agreement.

You have asked us whether,  in our opinion,  the Consideration to be received by
Cerberonics  pursuant to the Agreement is fair from a financial point of view to
CERBCO.  In  conducting  our  investigation  and analysis and in arriving at our
opinion set forth below, we have, among other things:

                    (i)  reviewed the Agreement and the proposed financial terms
                         of the Transaction;

                    (ii) reviewed  audited  financial  information  for the five
                         fiscal  years  ended  June 30,  1992  through  1996 for
                         CERBCO and Capitol,  as well as various other unaudited
                         financial information for CERBCO and Capitol;

                    (iii)compared  Capitol's  historical  results of  operations
                         with  that  of  certain  public   companies   which  we
                         considered relevant for our analysis;

                    (iv) visited    Capitol's    headquarters    and   conducted
                         discussions with Capitol's senior management concerning
                         the history and past  performance of Capitol's  current
                         business  operations,  and reviewed  certain  forecasts
                         provided  to us  in  the  course  of  such  discussions
                         relating to the business,  earnings,  cash flow, assets
                         and prospects of Capitol;

                    (v)  reviewed such other financial  studies and analyses and
                         performed  such  other  investigations  and  took  into
                         account   such   accepted   financial   and   valuation
                         procedures and considerations and such other matters as
                         we deemed relevant, including our

                           assessment of general and local economic,  market and
                           financial  conditions  which  have an  impact  on the
                           industry in which Capitol operates.

While we reviewed the  financial  terms of certain  transactions  involving  the
acquisition of companies in industries  comparable to Capitol's  operations,  we
did not  identify  a  sufficient  number  of  acquisitions  that we deemed to be
relevant for the purpose of our analysis and, accordingly, did not undertake any
analysis   comparing  the  financial  terms  of  the   Transaction   with  other
acquisitions.

In preparing our opinion, we have relied on the accuracy and completeness of all
financial and other  information  supplied or otherwise  made available to us by
CERBCO  and  Capitol,  or  which  are  publicly  available,   and  we  have  not
independently  verified such information or undertaken an independent  appraisal
or  valuation  of the assets or  liabilities  of  Capitol.  With  respect to any
financial  forecasts and projected expense reductions  provided by and discussed
with Capitol's  management,  we have assumed that such  financial  forecasts and
projected expense reductions  (together with the assumptions and bases therefor)
have been reasonably prepared and reflect the best currently available estimates
and  judgment  of  Capitol's  management  as to the  expected  future  financial
performance of Capitol.

This opinion is also given on the  assumption  that there are no  undisclosed or
unexpected  conditions  which would affect the value of Capitol's  assets or the
financial  condition or operations of Capitol or the expected  future  financial
performance of Capitol.

Our opinion is  necessarily  based upon market and general  economic  conditions
existing as of the date hereof.

The terms of our  engagement  are limited to expressing an opinion as to whether
the  Consideration  to be received by  Cerberonics  pursuant to the Agreement is
fair to  CERBCO  from a  financial  point of view and we were not  requested  to
assist and have not  participated in structuring or negotiating the terms of the
Transaction.  In addition,  our opinion does not address the relative  merits of
the Transaction and alternative business strategies involving Capitol, including
the sale of Capitol to third parties.

On the basis of, and subject to the foregoing,  were are of the opinion that the
proposed  Consideration to be received by Cerberonics  pursuant to the Agreement
is fair to CERBCO from a financial point of view.

Sincerely,
