HMG PRICE LIST


Licensing

Each volume licensed includes a hardcover book, knowledgebase data file, and if
licensed, HMG or HSIM OnLine diskette(s). The following fee schedule is per
volume and applies to the initial license. The annual renewal fee is equal to
40% of M&R's then-current license fee and is due on the anniversary date of the
license.

The knowledgebase file is designed to embed into your healthcare management
system. The data within these knowledgebase files are structured to allow
convenience access to the Guidelines. We also have a list of software vendors
who have developed applications that incorporate the Guidelines. This list is
available upon request. THE KNOWLEDGEBASE FILES DO NOT ALLOW VIEWING OR
PRINTING OF THE GUIDELINES FROM THE DISKETTE.

For those customers who do not want to create a custom application for viewing
selected guidelines, we recommend purchasing the network version of HMG or HSIM
OnLine. The HMG or HSIM OnLine network installation program supports
installation of components on a server, on a local or network Windows client,
and on stand-alone systems.

[HMG LOGO] HMG PRICE LIST


Licensing

Each volume licensed includes a hardcover book, knowledgebase data file, and if
licensed, HMG or HSIM OnLine diskette(s). The following fee schedule is per
volume and applies to the initial license. The annual renewal fee is equal to
40% of M&R's then-current license fee and is due on the anniversary date of the
license.

The knowledgebase file is designed to embed into your healthcare management
system. The data within these knowledgebase files are structured to allow
convenient access to the Guidelines. We also have a list of software vendors who
have developed applications that incorporate the Guidelines. This list is
available upon request. THE KNOWLEDGEBASE FILES DO NOT ALLOW VIEWING OR PRINTING
OF THE GUIDELINES FROM THE DISKETTE.

For those customers who do not want to create a custom application for viewing
selected guidelines, we recommend purchasing the network version of HMG or HSIM
OnLine. The HMG or HSIM OnLine network installation program supports
installation of components on a server, on a local or network Windows client,
and on stand-alone systems.

Dear Clients and Friends:

                       HMG PRICING AND LICENSING CHANGES

Enclosed is our new price list, effective May 1, 1998, for the Healthcare
Management Guidelines(TM) (HMGs). Our number one objective, like yours, is to
provide a quality product to clients at a reasonable price.

The extensive investment M&R makes to maintain a high quality product combined
with our effort to annually update the Guidelines creates a need to increase
prices. Therefore, the licensing price schedule and the price for individual
volumes for many of our publications will increase. Some clients, however, will
actually see a net decrease in cost depending on which volumes are purchased or
licensed.

The HMGs are a good value as measured by our clients' ability to reduce the
cost of healthcare. Many clients have seen a return on their HMG and related
infrastructure investment of more than 5 to 10 times the amount invested. Here
is an example that helps illustrate the potential savings when appropriately
implementing the Guidelines:

     The first year license price for a 100,000 member HMO using Volumes 1, 4,
     and 6 is $43,750. The net financial impact of reducing the length of stay
     for a patient for one day is about $1,000. A reduction of 25-bed days/1000
     for the plan over one year would save $2.5 million or about 60 times the
     cost of the initial license. Most of our clients save far more than 25-bed
     days/1000 in their first year and enjoy these savings over many years. Even
     considering the additional infrastructure sometimes required to implement
     the Guidelines, such as additional case managers, the value is far greater
     than its cost.

Highlights of the new HMG pricing:

BOOKS

-    We've introduced variable pricing per publication. For example, the content
     and extent of Volume 1 is different from that in Volume 3, so the volumes
     are priced to reflect this.

-    We now have the capability to provide Internet-based access to the HMGs.
     Internet subscriptions are discounted 10% from hardcover book prices.

-    The best healthcare management strategy is to maximize one's health status
     throughout the healthcare continuum. We are committed to this concept and
     want to encourage use of those volumes that represent the core of this
     concept. We now have a package price for purchasing a set containing

     Volumes 1, 4, 5, and 6. Previously, we offered savings for purchasing the
     Continuum of Care Package (Volumes 1, 4, and 6). Now you can save even more
     by purchasing the Primary and Continuum of Care Package which includes
     Volumes 1, 4, 6, and Volume 5, Ambulatory, Primary, and Pharmaceutical
     Care. The Volume 5 diskette will, for the time being, not be integrated
     with Volumes 1, 4, and 6 until technical issues are resolved. Nevertheless,
     the package offers a 17% discount to purchase all four volumes.

LICENSES

-    We have moved to a 12-month, annual subscription for licenses, thereby
     eliminating the need to relicense when a new edition is released. When new
     editions are released during the 12-month license you will automatically
     receive the new edition at no additional license fee. In some cases this
     could mean you would receive more than one edition during the 12-month
     period. Licenses that are not renewed within 30-days of the renewal date
     will expire and you must cease use of the HMG/HSIM products.

-    The renewal fee remains at 40% of the current standard license fee. Since
     NCQA requires current Guideline use, the annual renewal helps you meet
     those requirements.

-    We have eliminated the cumbersome, staggered renewal dates on each product
     licensed. You will now have one simple-to-implement renewal date for all
     licensed HMG/HSIM products. For example:

          You have licensed Volume 1 with an expiration date of 8/31/98 and also
          licensed Volume 5 containing an expiration date of 11/30/98. Sixty
          days prior to 8/31/98 we will send you an invoice for 40% of the
          standard licensing fee for Volume 1 plus a prorated amount (in this
          case 9/12ths) of the 40% renewal fee for Volume 5. The new renewal
          date for both Volumes 1 and 5 becomes 9/1/99.

-    We are introducing a new service: complimentary technical consulting. In
     addition to the 10% training credit currently included with your license,
     you will receive the equivalent of 5% of your license fee each contract
     year for telephone- or email-based technical consulting regarding our
     software documentation. This consulting is designed to help you integrate
     the Guidelines into your healthcare management system and is provided
     exclusively by the HMG/HSIM Information Technology group.

If you have any questions about our new pricing or licensing process, please
call our Client Services Department toll-free at 888/HMG-HSIM (888-464-4746).
We appreciate your support of the Healthcare Management Guidelines and welcome
your suggestions on making the publications even more valuable to you.

Sincerely,

THE HMG/HSIM DEPARTMENT
